Cement kiln mechanically actuated arm device

Abstract

The invention relates to a mechanical operation arm device for a cement kiln. An A motor is connected with chains; the chains are connected with a gear rack retractor device; the gear rack retractor device is fixed on the chains and arranged on a side rail; the A motor is fixed on the slide rail; a gear rack is fixed on the gear rack retractor device; a drilling steel is connected with the gear rack; the slide rail, a B motor, a positioned wheel, a B roller and an A roller are fixed on a platform; and a circular rail is fixed on a kiln body. The device has the advantage of arbitrarily selecting various areas of the circumstance of a kiln surface for operation, realizing the aim of closed operation for a vertical kiln, reducing the exhaust of smoke gas from a kiln door, maintaining the kilnsurface temperature, reducing heat consumption, saving the cost of the vertical kiln cement production, and ensuring that the used dust collection device has no condensation, no attachment to a beltand low corrosion degree, etc., reducing labor intensity, and reducing the investment. The device has no mechanical faults, good running effect, no influence on normal production for the vertical kiln, stable performance and high working efficiency, and makes capacity upsizing and automatic control for the vertical kiln possible.

Description

technical field [0001] The invention relates to a cement kiln mechanical operating arm device. The invention belongs to the technical field of cement building materials. Background technique [0002] The operation of the kiln surface of the cement kiln is a major difficulty in the clinker production process of the cement kiln. During the production process of cement kiln, after water is added to the raw meal powder, spherical raw meal balls are formed from the ball forming plate, 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 surface operation is mainly to manually observe the kiln surface, and then use steel brazing to operate the kiln. The temperature of the firing zone must be maintained during kiln calcination, otherwise the quality of clinker will be affected, so the thickness of the wet material layer must be thickened to maintain the temperature in the k...

AI Technical Summary

Problems solved by technology

Now as the diameter of the kiln increases, that is, the unit cross-sectional area of ​​the kiln increases, the depth of the operation is deepening, and the steel brazing used by the workers is getting longer and heavier. Because the physical fitness of the workers cannot keep up, the kiln The operation of the kiln surface is becoming more and more difficult, the concentration of flue gas on the kiln surface is high, the firing conditions in the kiln are variable, the temperature of the kiln surface is high, and 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.
