Description

one

The invention relates to the production of products, materials and products that are subjected to heat and moisture treatment during the production process and can be applied to the enterprise. x industry building materials c.

A known installation for the thermal and moisture treatment of materials and products, comprising a heat generating unit of aerodynamic action and a chamber divided by a heat-emitting screen into a working volume AND closed screen.

The purpose of the invention is to provide the possibility of adjusting the processing parameters in a wide range and to increase the efficiency of the installation.

This is achieved by the fact that the tenlo-emitting screen and the enclosure of the chamber are made with a system of openings blocked by shut-off regulating devices, and the heat generating unit of aerodynamic action is connected to the chamber with the possibility of circulating the coolant through the screen of the closed cavity and through the working volume of the chamber. The aerodynamic unit is equipped with an additional heater, for example, and an induction, mounted, suction and discharge pipe.

FIG. 1 shows the proposed installation, the general view; in fig. 2 - section along

A-A in FIG. one; in fig. 3 - section along B - C

FIG. 3; in fig. 5 - section along Gyg on fit. four.

The installation consists of a chamber} and a power unit, which is a combination of a unit of aerodynamic action 2 with an induction heater 3, which in turn is a metal hollow insert connecting the suction 4 and

The discharge 5 branch pipes of the aerodynamic heat unit, which are wrapped in special conductor by needles, which provide additional 1-induction heating of the coolant.

Chamber 1 contains a heat insulating barrier 6 and a heat radiating screen 7, which separates the chamber / into a working volume 8 and a closed screen 9.

The heat-emitting screen is made up of a system of holes a, covered by 3anopiHiiMH regulating devices, equipped with removable cover plates, slide gates or louvered grilles with electromechanical or other types of drives, which allow changing the cross-sectional area of the holes in the screen and thereby adjusting the rate of suction. heat carrier of bodies (air, gas, vapor-air mixture)

through the working volume of the camera.

On the stationary part of the overlap of the working chamber / capacity 10, filled with water, is mounted. The humidification system of the working space of the chamber consists of piped distributing pipes with nozzles-distributors 11 connected to the vessel Yu by means of shut-off valves 12. In the enclosure of the chamber there are openings blocked by lids or shutters of regulating devices 13 that provide air circulation in the working volume eight.

The loading window in the stationary part of the overlap of the chamber / blocked by a removable or hinged lid 14.

Installing ra: bots next; im the way.

Products, materials or products to be processed: they are thermally treated, fed to the working chamber 8 and closed with a lid 14. The power unit is turned on. When the power unit is in operation, the coolant begins to circulate in the screen space 9, which has the ability to circulate through the working volume 8 through the system of holes a in the heat-emitting screen 7, and the rate of suction (circulation) through the working volume depends on the degree of overlap of the bore through sections gates or louvres. The type of overlap of the holes is chosen depending on the purpose of the installation and the requirements of the process of thermal and moisture treatment.

If necessary, fine adjustment in a wide range of speed. Parameters of the coolant orifices are covered with louvered grilles. If the heat treatment process requires less precise, but in a fairly wide range, the adjustment of the velocity parameters of the coolant, the holes are blocked by rotary or with sliding gates. And finally, if it is necessary to change the rate of heat carrier suction through the working volume of the chamber not during the heat treatment cycle, but when changing the type of product, material or product, the holes are covered with overlays (sheets) that are attached to the heat radiating screen 7 bolts or other types of fasteners in order to completely or partially overlap or, on the contrary, open holes.

The water supply system to the heat-emitting screen 7 includes, if necessary, an increase in humidity in the working volume, and with the help of shut-off regulating devices 13 dry air is supplied to the working volume and ejected from it into the atmosphere of humid air or steam, i.e., air is exchanged working volume.

The amount of heat supplied during the heat treatment cycle to products, materials and products placed into the working volume is varied in time by periodically turning on and off the power unit or changing its heat output.

The installation can also be performed with a tunnel-type chamber for the purpose of continuous heat treatment of materials and products.
