SU435506A1 - DEVICE FOR REGULATING THE LEVEL OF REDUCED MATERIAL - Google Patents

Description

one

The invention is intended to control the level of a material having a high temperature, for example, expanded clay gravel, produced by rotating and glowing to a luminescence temperature.

A device for adjusting the level of a hot material containing a radiation pyrometer, sighted on the opposite wall of the bunker, a regulator and a discharger is known.

The known device has a number of disadvantages: high inertia, due to the large thermal inertia of the bunker itself, its low control accuracy and, as a result, significant fluctuations in the regulated level.

The purpose of the invention is to reduce the inertia and increase the accuracy of regulation.

The goal is achieved by the fact that the device is equipped with a thin plate that is installed in the sighting zone of the pyrometer and cooled to a temperature below the luminescence temperature.

The invention is illustrated in the drawing.

The red-hot luminous material 1 enters the receiving bin 2, in the wall of which a dark spot is arranged, which is a metal thin plate 3, embedded into the lining of the bunker wall and

cooled by a fan 4. A dark pyrometer 5 is sensed on a dark spot, the signal of which is perceived by controller 6 acting through a magnetic starter 7 and a servomotor 8 on a variator 9 that changes the speed of the plate unloading device 10.

The proposed device works as follows.

By reducing the level of material 1 in the receiving bin 2, the thin plate 3 is opened. The radiation pyrometer 5, sighted on a thin plate 3, sends a signal to the controller 6, which through the magnetic starter 7 and the servomotor 8 acts on the variator 9, reducing the speed of the plate unloading device 10. This leads to an increase in the level of the material in the receiving hopper. If the thin plate overlaps the material,

Then the radiation pyrometer 1B enters the radiation of incandescent light of the naked material. The signal of the radiation pyrometer through the controller increases the speed of the material unloading. Thus, the level is adjusted in the area of the thin plate.
