Transferred via translate.google.com The country is actively under construction. Constructed in urban areas. Constructed in rural areas. In this regard, a rapid rise in the prices of construction materials, brick, gazosilikatnye material. I offer you the technology to the disclosure of know-how and working drawings for the device through which you can frit, gazosilikatnye units directly at the construction site erected facility, near the sources of construction sand. Gazosilikatnye blocks are obtained in 2-3 times cheaper. So: A project installation - steam autoclave, producing steam and accumulated in a sealed tank with a pressure and forcing it to ferry food, material, raw material, in this capacity original idea - combine steam boiler and an autoclave in a single device, with the possibility of transporting this device pulling the vehicle in any places. The source of thermal energy are heating oil, gas, diz.toplivo. The proposed device has no analogues in the world. It is mounted on trailers with two axles. Has drawings. The basic element in the development of derived container on the trailer, produced by JSC "Bobruiskagromash (MZHT-F-8). Obtained a patent for the invention. Authoring. Silicate materials are sintered at a temperature of 150-200 degrees in an atmosphere of saturated steam. Cellular concrete, gazosilikatnye blocks are sintered at a temperature of 175 degrees and a pressure of 0.07 MPa. Simplifies the entire procedure. Installation is not subject to RULES OF THE DEVICE AND SAFE OPERATION pressure vessels PB 03-576-03. He does not need to register. He does not need a license. This device is the internal capacity of an autoclave is warming up to more than 200 degrees, from the steam boiler, which is the convex part of the domestic capacity autoclave. Furthermore, piped water is not passed, and couples. This device, with the formation of calcium gidrosilikatov water consumption occurs in the form of saturated steam. As the reduction of moisture vapor, water is sprayed over the source and the storage of thermal energy. Steam passing through the storage of heat energy is warming up to teperatury 150-200 degrees. At the same time, pressure must be no higher than 0.07 MPa. if the increased need стравить. Couples enrolled in the autoclave, with a temperature of 150-200 degrees Celsius and a pressure of 0.07 MPa. forms a vortex rotational motion, for better penetration of steam into the kernel gazosilikatnyh blocks. Gazosilikaty autoclave hardening cheaper than foam and cellular concrete, close to the environmentally friendly building materials. Background radiation from them is lower than that of construction materials, the main components of astringent which is cement. Although in both cases, they do not go beyond the SNIP. In the future, gazosilikaty autoclave hardening will be further developed and out of the facilities housing foam blocks neavtoklavnogo hardening. Technology to gazosilikatov with characteristics similar to a tree at the beginning of XX century, was invented by Swedish architect A. Eriksson. In 1924, this story has received international patents, and recognition. In the simplest set of technological equipment for the production gazosilikata autoclave hardening under conditions of small-scale production include: -sg; -autoclave; - A mechanical sieve for screening of coarse fractions; -doser for dosing the filing of sand in a wet grinding mill (In a small-scale production can be produced dose-dimensional volume buckets); ball-mill; mechanical sieve to separate the coarse fraction of residual sludge and sand milling bodies; -mortel -mixer for mixing the aluminum paste; form for gazosilikatnyh or penosilikatnyh blocks; The technological process of production gazosilikatnyh blocks from the date of the invention is not changed: Wet sand is fed to a mechanical sieve, in a small-scale production, in a hand, shovels. Here he is separated from the coarse fractions. Next, the sand is fed into the ball mill for grinding. The process of grinding is carried out by milling bodies. At the exit from the mill sludge through the discharge opening falls on a sieve, through which eliminated the residual coarse fraction and milling body. Further, in certain proportions: sand screened out, melkomolotaya quicklime and water are served in the appropriate temperature mortel. In mortel components are mixed, with the participation in the process of mixing steam. Pre-mixing of the aluminum paste is happening in the intermediate tank with agitator (mixer). After adding aluminum mortel dispersion and mixing with the bulk silicate mixture is poured into a container. From tanks silicate mixture to a certain dosage forms to be submitted. Forms must be constantly on the warmed up state. In the process of chemical reaction between aluminum powder and calcium oxide hydrate allocated hydrogen, which vspuchivaet silicate mixture. At a certain time when it begins to acquire a rigid structure, vspuchennuyu of the silicate masses need prikatat or cut. Then gazosilikatny unit shall be exempt from the raw form and is fed into an autoclave for sintering. In an atmosphere of saturated steam at a temperature of 150-200 degrees, and the corresponding pressure of 8-10 atm., The formation of calcium gidrosilikatov - water resistant and durable monolith. Saturated superheated steam is fed into a steam autoclave, who may make steam boilers In order to organize small-scale production gazosilikata needed: 1. Mechanical. sieve for screening coarse fractions (eg deck shale shaker AC-3) - 22000rub. 2.Sharovaya mill (for example MSh-2, the mass loading 350kgyu) - 725000rub. 3. Mechanical sieve to separate the residual coarse fractions sand slurry and milling bodies (eg deck shale shaker AC-3-22000rub. 4.Rastvorosmesitel (eg CM-Mini) - 37000rub. 5.Formy for gazosilikatnyh or penosilikatnyh blocks (For example, the form of a metal volume of 1 cubic meters, 35 blocks, the size of 500h300h200)-45000rub. 6.Parogenerator (for example, boiler steam "Luga-Lotus CWR 1.0 MW light obmurovke, steam 1200kg/chas)-413700rub. with the value obmurovki. 7.Avtoklav for the sintering of silicate materials, min. Price -1000000 rub. 8. Obmurovka autoclave, foundation preparation, installation -100000 rub. 9. Production area -3000000 rub. 10. The main steam to the steam. - 10000 rub. Total: EUR -5374700. The amount is impressive for a novice entrepreneur. But do not lose heart and abandon the intended target. Consider, without which you can do in the first stages of the production process .. Mechanical sieve, mortel, forms for gazosilikatnyh and penosilikatnyh blocks necessary expenses for their purchase amount - 104000rub. Ball mill is designed for fine grinding siliceous sand. Grinding increases the specific surface siliceous component and enhances its chemical activity. As a result of mixing sand fine grinding with the other components are obtained gazosilikatnye blocks of good quality. Deletion of the ball mill process, we are obliged to introduce cement, to improve the strength characteristics. It is quite possible. Basic equipment, without which no organization can process: steam, autoclave, obmurovka and more productive area for an autoclave, the main steam - 4523700rub. Ways to reduce the cost of capital investments. Offer a steam autoclave and use steam autoclave, steam generating and accumulating in a sealed tank, with excess pressure, and the impact of this steam to the food product, material, raw material. Obmurovka it is not needed, as well as inside the bars, he skinned hardwood and download to the internal plating centralizers. It is producing steam in the mobile version. What this gives: 1. Mobility. At the time of production gazosilikatov and capacity release have the need for its displacement. 2.Mnogofunktsionalnost. In spring and summer can be gazosilikatnye blocks, and creating a reserve, in the autumn to switch to the formulation of essential oils (fir, pine, spruce, etc.) or the sterilization / pasteurization of canned foods. (this is in the southern regions of the country) 3. There is no need for the construction of major buildings. Enough overhang. A technical documentation on a mobile version of steam autoclave, capacity of 6 cubic meters, based on the reconstruction of tanks on the trailer, produced by JSC «Bobruiskagromash». 1610mm diameter tank. The technological regime of installation, you can choose different. From the temperature of 150-175 degrees Celsius and pressures up to 0.07 MPa, to a temperature of 175-190 degrees Celsius and pressures up to 0.8 MPa. In the second case requires registration at the Kotlonadzora. The cost of acquiring capacity on the trailer, second hand rub -100000. The cost of reconstruction - 150000 rub. Total: - 250000 rub. Total cost: EUR -354,000. Calculate the cost of production gazosilikatnyh blocks (4 cubic meters of silicate mass, part of the autoclave for sintering) Raw materials: 1.Kvartsevy sand is 3.6 cubic meters - 500rub. 2. Quicklime, fine grinding 0.4 cubic meters (300kg) - 600 rub. GOST 9179-77 -- 3. Cement (50kg) - 350 rub. 4.Alyuminievaya paste the PAC-3, or PAC-4, (2 kg) -300 rubles. Energy: 4. The source of thermal energy, wood (2 cubic meters) - 1000 rub. 5. Electricity. - 300 rub. 6.Zarabotnaya charges two employees for a cycle (12 hours) - 2000 rub. Total: -5050 rub. Cost of products 5050:4 = 1262.5 rubles / m³. Sale price of producers - 3400rub/kub.m. Profit without tax - 2,134.5 rubles per cub. The most blatant is estimated for the 6 month pay off all costs of acquisition and construction oborudotaniya.
