Abstract

The invention relates to the construction industry, in particular to batch chambers for the heat treatment of concrete and reinforced concrete products. The purpose of the invention is to improve the uniformity of heating products and simplify the design. The Yamna chamber contains steam supply manifolds with a switch and steam-air mixers located in two rows on the walls of the chamber. Each steam supply collector is connected to steam-air mixers of one of the lower and one of the upper rows, spaced on opposite walls of the chamber, with the steam-air mixers directed downward by the nozzles. The temperature difference along the height of the chamber does not exceed 1.5-2 ° C. 3 il.

With the passage of the gaps, the air mixture part of its thermal energy gives to the product and comes to the opposite wall with a lower temperature. In order to eliminate uneven heating of products at opposite walls of the chamber, switch 5 periodically switches the steam supply from collector 3 to collector 4. When steam is supplied to collector 4, the direction of steam supply in the gaps changes, i.e. steam is supplied from the opposite wall to collector 3.

The mixing chamber is provided in my chamber both in the vertical and horizontal planes of the vapor-air mixture.

The invention relates to the construction industry, in particular to batch chambers for the heat treatment of concrete and reinforced concrete products. The purpose of the invention is to improve the uniformity of heating products and simplify the design.

FIG. 1 shows me the camera, a general view; in fig. 2 is a diagram of the distribution of vapor-air flows, cross section; in fig. 3 shows the node I in FIG. 1. The Yamna chamber consists of walls 1, covers 2 of collectors 3 and 4 with a switch 5. Steam-air mixers 6, located in the lower row near one of the walls and in the upper row at the opposite side. 15 As a result, the temperature difference along the positive wall is attached to the collection height of the camera does not exceed 1.5-2 °. In the retor 3, and steam-air mixers 7, as a result of the upper and lower products, are installed, respectively, to the collections they collect almost simultaneously

toru 4.: strength. Eliminated overheating of the upper

The camera works as follows. Rus products, resulting in savings

After the chamber has been loaded, approximately 228 kg of steam per day for one product is covered with a lid 2, a chamber,

and steam is supplied to the collectors 3 or 4 alternately. When steam is supplied to the collector 3, the lower row mixers create suction on one wall of the chamber and direct the vapor-air mixture 25 into the gap between the chamber floor and the products against the flow of the steam-air mixture of the upper row mixers 6. As a result, a pressure zone is created near the wall with working mixers of the upper row, and in the zone of heating products and simplifying the opposite, a zone of reduced pressure pressure, each steam supply manifold

it is connected to steam-air mixers of one of the lower and one of the upper rows located on the opposite walls of the chamber, with the engine and its direction downwards, i.e., the intermixed air mixers are directed downstream by the mixture.

Claims (1)

Invention Formula A pit chamber containing wall barriers, a bottom, a lid and steam supply manifolds with a switch and steam-air mixers arranged in two rows on the walls of the chamber, characterized in that, in order to increase uniformity. Therefore, the vapor-air mixture rushes into the gaps between the products, and the vapor-air mixture is constantly taken at the top of the chamber. With the passage of the gaps, the air mixture part of its thermal energy gives to the product and comes to the opposite wall with a lower temperature. In order to eliminate uneven heating of products at opposite walls of the chamber, switch 5 periodically switches the steam supply from collector 3 to collector 4. When steam is supplied to collector 4, the direction of steam supply in the gaps changes, i.e. steam is supplied from the opposite wall to collector 3. The mixing chamber is provided in my chamber both in the vertical and horizontal planes of the vapor-air mixture. As a result, the temperature difference in the height of the chamber does not exceed 1.5-2 °. In renaissance heating products and simplifying the design, each steam supply collector Invention Formula A pit chamber containing wall barriers, a bottom, a lid and steam supply manifolds with a switch and steam-air mixers located in two rows on the walls of the chamber, characterized in that, in order to increase uniformly FIG.
