Hydraulic driving device for thickener

Abstract

The invention discloses a hydraulic driving device for a thickener. The hydraulic driving device for the thickener comprises a driving device formed by a power source, a speed reducer and an output shaft, wherein the power source is connected with the speed reducer. The hydraulic driving device for the thickener is further provided with a hydraulic lifting device formed by a hydraulic oil cylinder and a guiding shaft, the hydraulic oil cylinder and the guiding shaft are connected through a piston rod, the hydraulic oil cylinder is arranged above a connecting plate, and the guiding shaft is arranged below the connecting plate. An advanced and reliable electrohydraulic combined control system is adopted, pressure of a hydraulic system serves as control signals, the hydraulic driving device for the thickener can automatically lift a rake according to the resistance which a rake arm is subjected to, signal detection is comprehensive and accurate, motions are safe and reliable, and rake pressing is avoided.

Description

technical field [0001] The invention relates to a gravity settling separation thickener driving transmission device for a clarification tank. Background technique [0002] The thickener is the main equipment used in various industries to realize the gravity sedimentation separation of the homogeneous liquid-solid mixture. It is a kind of production equipment with large volume, low power, low speed and high torque. Most of them operate continuously for a long time. , has high requirements for the safe operation of the equipment, and the driving device is the main component of the thickener. Most of the original thickener driving devices are driven by a reducer to drive a large worm gear reducer. The transmission route is: motor → reducer → chain drive → worm gear reducer → worm gear drives the output shaft to output torque, because the worm gear reducer It has disadvantages such as low efficiency and high heat generation. The total transmission efficiency of the entire drive...

AI Technical Summary

Problems solved by technology

Depending on the specifications of the driven thickener and the difference in the settling medium, there will be an output that requires greater torque; and the power source used by the thickener is an asynchronous motor, and there are differences in the production process of the intermediate drive, plus the self-locking, The input and output cannot be reversible. If you want to use multiple reducers to drive a worm reducer, it will not work properly due to synchronization problems, and there is even a danger of damaging the worm reducer.

When it is necessary to output a large torque, the specifications and models of the final worm gear reducer increase accordingly. As a result, the entire drive device is bulky and heavy, and the direct consequence is that the design requirements of the bridge bracket supporting the drive device are high. There are many consumables and high cost; during use and maintenance, it is difficult to repair the worm gear after wear and tear in the future, and the replacement cost is high
