Rotary table filter distribution valve electric lifting device

Abstract

The invention provides a rotary table filter distribution valve electric lifting device. A rotary table filter comprises a central stand column. The electric lifting device is integrally mounted in the center stand column. The electric lifting device comprises an electric hoist, a steel wire rope, a lifting bracket, a lifting rail, a travel switch and a mechanical protection device. The electric lifting device is integrally located in the center stand column and does not occupy any external space, and adjustment and maintenance of the filter are facilitated. The corresponding electric hoist isselected as a power source, the steel wire rope is used as a lifting medium, a hydraulic power unit and a hydraulic cylinder are replaced, the production cost is greatly reduced, and operation is simpler. In addition, a lifting protection measure is mounted in the electric lifting device, the lifting protection device can be used, the safety of personnel and equipment are ensured, the synchronization is improved, and the failure rate is relatively low.

Description

technical field [0001] The invention relates to a turntable filter, in particular to an electric lifting device for a distribution valve of a turntable filter. Background technique [0002] The rotary table vacuum filter is a high-efficiency vacuum filter equipment that operates continuously. The slurry to be filtered is continuously fed from the upper hopper. The cake is conveyed and discharged by the unloading screw after being washed several times and blotted dry. The filter rotates horizontally for one week, and completes the basic process of feeding—(back blowing)—filtering—washing—drying—discharging. The speeds of the main turntable and the unloading screw are controlled by frequency conversion to meet the needs of different process operations. The turntable vacuum filter has the characteristics of simple structure, good process adaptability, stable operation, fast dehydration, and good washing effect. For the suspension with fast desizing, it has the advantage of la...

AI Technical Summary

Problems solved by technology

The lifting of the traditional distribution valve adopts mechanical screw lifting, the manual operation intensity of this process is relatively high, and the maintenance time of the equipment is long

Later, manual lifting was changed to hydraulic lifting. After years of market application and user feedback, the following problems were found: 1. The cost is relatively high; 2. The debugging work is cumbersome, and multiple exhaust and deflation operations are required; 3. 1. There is hydraulic oil leakage during use and adjustment, which pollutes the environment; 4. Since the hydraulic system is often out of use for a long time, it will be out of sync when it is used again; 5. The skill level of the operator has a great impact on the use effect
