Automated control method for shaft kiln distributing device and the device

Abstract

The invention relates to the automatic control method of the shaft cloth implement and its device, the method is joining the signal which controls the cloth implement rotated into the cloth implement by the procedure controller; the cloth implement rotates one lap that is set one lap of the cloth in the cloth region; when the cloth implement rotates N times, set N lap cloth in the cloth region; joining the signal which controls the steel wire rotated of the rotating machine into the rotating machine; the angle of the sprinkler of the cloth and the horizontal changes between 0 and 90 degree; based on the cloth region the circle divided into three or more circle layer with one heart to carry on the bed cloth automatically; the interval distance of the different circle and the circle centre and the cloth lap of the different circle are controlled by the process controller. The merit: optionally select the multiple circumferential surface area or space cloth, control the time of the region cloth, and realize the aim of the shaft shut operation, reduce the discharge of the smoke from the kiln door, keep the kiln temperature, and reduce the energy cost of the ripe cloth burning, save the cost. It reduced the labor intensity, not blocking the kiln.

Description

technical field [0001] The invention relates to an automatic control method and device for a vertical kiln distributor. The invention belongs to the technical field of cement building materials. Background technique [0002] The distribution of shaft kiln cement is a major difficulty in the shaft kiln clinker production process. In the shaft kiln cement production process, after water is added to the raw meal powder, spherical raw meal balls are formed from the ball forming disc, and then the distributor is evenly distributed to the wet material layer in the kiln according to the kiln conditions. The method currently used for cement kiln distribution is mainly to manually observe the kiln surface, and then control the distributor to perform distribution. Cement shaft kiln material distribution is carried out continuously, and the material distribution device is evenly distributed to the kiln surface, but the smoke concentration on the kiln surface is high, it is difficult ...

AI Technical Summary

Problems solved by technology

Cement shaft kiln material distribution is carried out continuously, and the distributor is evenly distributed to the kiln surface, but the smoke concentration on the kiln surface is high, it is difficult to visually observe the condition of the kiln surface, and the firing conditions in the kiln are changeable, which greatly affects the uniformity and accuracy of the material distribution. influential

The temperature of the kiln surface is high. After the kiln door is opened, the labor intensity of the workers is high, which will affect the temperature change in the kiln and increase energy consumption.

It also affects the dust collection equipment of the shaft kiln, especially the large bag dust collector. If the flue gas entering the dust collector is too low, it will cause the cloth tape of the dust collector to stick, condensation, corrosion, etc., and the maintenance work of the dust collector volume increase

cause direct or indirect economic loss
