Description

The invention relates to the production of building materials and is intended to accelerate the curing process of building materials.

A steaming chamber is known, including a base, walls made with an inner rim, a water seal frame mounted on the walls around the perimeter, a screen whose inner surface is made with steam and water insulation coating and thermal insulation, a thermal expansion compensator, a steam pipe, a groove for condensate drain, and the base has transverse protrusions, the screen is made in the form of a frame of lightweight profile, the inner surface of the walls, base and screen of the camera are covered with a layer of liquid ceramic thermal insulation "Corundum". [ RF patent No. 110327, IPC B28B 13/00, publ. 11/20/2011. Kurbatov V.L., Fursov A.V., Fuzulutdinova N.F., Ivaschenko O.V. "Steaming chamber"].

The disadvantages of this camera is the need to use an external steam generator, as well as the absence of heat-accumulating systems.

The prototype was taken by a pool-type steaming chamber containing a grating installed above a steam-insulated chamber base, high-temperature heating elements were passed along the chamber base, and the part of the chamber between the base and the grating floor was filled with water [RF Patent No. 160980, IPC B28B 11/24, publ. 04/10/2016. Cherepov V.D., Medyakov A.A., et al. “Steaming chamber of the pool type”].

Its disadvantage is the complexity and cumbersome design.

The technical result of the invention is to save thermal energy and improve the quality of the processed materials through the use of heat and moisture treatment.

The technical result is achieved in that a steaming chamber containing a thermally insulated sealed housing, on the base of which high-temperature heating elements are hidden, hidden by a layer of water, differs in that the radial fan is installed externally on the chamber housing and connected to it via an exhaust duct on one side and the supply channel on the other, also at the outlet of the supply air duct with the help of a holder an air tubular electric heater (TEN) is installed, a humidifier is installed in the ceiling on the rails yuschaya system consisting of pipes and nozzles connected to the water supply, and the side walls having guiding chamber, in which are set to accommodate the lattice construction materials.

The steaming chamber is illustrated by drawings, where in FIG. 1 is a side view, and FIG. 2 is a front view.

The steaming chamber consists of a thermally insulated sealed enclosure 1 with a door 2, on the base of which high-temperature heating elements 3, hidden by a layer of water, are passed. Outside, a radial fan 4 is mounted on the camera’s body, connected to the camera through exhaust 5 and supply channels 6, the holder of the air heater 7. Inside the camera body there is an air heater 8, ceiling guides 9, a humidification system of pipelines 10 and nozzles 11, side rails 12 and gratings for the placement of building materials 13.

The steaming chamber operates as follows.

Inside the chamber are placed pallets with building materials, which are installed on the guides 12 and the grilles 13, so as not to touch the housing 1 of the camera and door 2. Then the chamber is hermetically closed. The heating elements 3 are turned on, and the water located in the base of the chamber as a result of heating evaporates, creating a medium of saturated water vapor in the chamber. In this case, the radial fan 4, drawing air from the chamber through the supply channel 6, passes it through the exhaust channel 5 and the air heater 8 installed using the holder 7. On the ceiling of the housing 1 of the camera on the guides 9 there is a humidification system connected to the water supply, when turned on which water through a system of pipelines 10 through nozzles 11 enters the drying space of the chamber. The number of nozzles depends on the volume of the drying chamber. At the end of the steaming of the products, the water supply stops, after cooling the product is removed from the steaming chamber.

The application of the proposed technical solution allows achieving a technical effect in comparison with the prototype: reducing heat loss, the possibility of thermal insulation in the existing design of the chamber, reducing the time of the technological process, provides more uniform temperature conditions in the chamber due to the accumulation of heat by the water located in the base of the chamber.
