Problems solved by technology

[0003] At present, the thickener does not have a torque measurement and automatic control system, so it is impossible to know the change of the torque of the rotary rake after starting, let alone effectively control the operation of the thickener at different stages, parking and the lifting of the rake body. The operation is difficult. Sometimes high power drives small loads, and the power factor is low; sometimes overloaded operation can easily cause equipment and electrical failures, or even damage

Embodiment Construction

[0013] With reference to the attached drawings, the automatic torque control system of thickener is mainly composed of torque measuring device and torque control part. The torque measuring device is mainly composed of housing 1, spline bushing 2, sliding sleeve 3, butterfly spring 4, sensing shaft 5 and torque pointer 6. The spline bushing 2 and sensing shaft 5 are located on the same axis Inside the housing 1, the front and rear central holes of the housing 1 are respectively passed through. The end of the sensing shaft 5 that is adjacent to the spline sleeve 2 is a mating end 7, and the mating end 7 extends into the center hole of the spline sleeve 2. The spline bushing 2 and the reducer shaft are connected by a spline, and the two can be axially displaced relatively. The sliding sleeve 3 and the butterfly spring 4 are located in the housing 1, and a bearing is provided in the sliding sleeve 3 for supporting the spline shaft sleeve 2. The limit plate 8 is fixed on the inner side...

Abstract

The automatic torque controlling system for thickener consists of mainly a torque measurer and a torque controller. The torque controller includes cams of different sizes on the rotation shaft meshed with the sensor shaft in the torque measurer, micro switches on one side of each cam, and relay connected to the micro switches and with contacts connected serially in the circuit comprising thickener driving motor and lifting motor. The activating micro switch feeds signal to the relay in the circuit comprising thickener driving motor and lifting motor, so that the relay turns on or off the circuit. The present invention can control the operation of the rotating harrow effectively according to the varying load while showing real-time torque. The present invention has convenient operation and low fault rate.

Description

[0001] This application is a divisional application of the patent application with the application number: 2004100138770 and the invention title: thickener torque measuring device and torque automatic control system. The original application date is January 12, 2004. Technical field [0002] The invention relates to an automatic torque control system for a thickener. Background technique [0003] The current thickener does not have a torque measurement and automatic control system, so it is impossible to know the change in the torque of the rotary harrow after starting, let alone effectively control the operation of the thickener in different positions, stopping and the lifting of the harrow body, which is difficult to operate. Sometimes high power drives a small load with low power factor; sometimes overload operation can easily cause equipment and electrical equipment failures or even damage. Summary of the invention [0004] In order to overcome the inability in the prior art ...
