Method and device for automatic control of thermal state in chamber-type drying chamber for block wet billets

Abstract

The invention discloses a method and a device for automatically controlling the thermal state of a block-shaped wet billet chamber-type drying chamber. The hot air with residual heat is sent into the block wet billet drying chamber, and then the gas discharged from the block wet billet drying chamber is discharged into the exhaust pipe, and part of the discharged gas is introduced into the block wet billet drying chamber Adjust the humidity in the room; through the computer control device, the electric air volume adjustment valve, the electric tide valve and the controllable heat supply fan are controlled, so as to realize the closed-loop automatic control of the thermal state of the block wet billet chamber drying chamber . The invention not only has the advantages of effectively reducing human resources and rationally utilizing energy, but also has the advantages of simple structure, good product quality and high production efficiency.

Description

technical field [0001] The invention relates to a method and a device for automatically controlling the thermal state of a block-shaped wet billet chamber-type drying chamber, and belongs to the technical field of automatic control of drying block-shaped wet billets. Background technique [0002] At present, most domestic sintered brick factories have a low degree of automation, which keeps the production cost high and causes great economic losses to the enterprise. In order to solve this problem, many brick factories use computers to control the controllable heat supply fans, that is, to automatically adjust the temperature of the drying chamber through the computer control of the controllable heat supply fans. This single open-loop control method, although the temperature of the drying room can be controlled in the required range, the humidity in the drying room and the temperature rise and fall time cannot be effectively controlled automatically, so the product quality is...

[0002]At present, most domestic sintered brick factories have a low degree of automation, which keeps the production cost high and causes great economic losses to the enterprise

In order to solve this problem, many brick factories use computers to control the controllable heat supply fans, that is, to automatically adjust the temperature of the drying chamber through the computer control of the controllable heat supply fans. This single open-loop control method, although the temperature of the drying room can be controlled within the required range, the humidity in the drying room and the temperature rise and fall time cannot be automatically controlled effectively, so the product quality is still not ideal.

In particular, the existing open-loop control method cannot reduce the gas discharge, which not only wastes energy, but also causes great pollution to the environment.

Therefore, the existing method for controlling the thermal state of the block-shaped wet billet drying chamber is still not ideal.
