Problems solved by technology

If the slurry feeding speed is lower than the pumping speed of the slurry pump, the liquid level of the slurry in the slurry storage tank is too low, which will cause the slurry pump to suck up and seriously affect the service life of the slurry pump
For purifiers with manual monitoring and manual adjustment, the operator usually patrols the site and immediately adjusts the pulp intake manually, resulting in a lag in manual adjustment
Ultrasonic liquid level gauges also have disadvantages such as high cost, and the measurement accuracy cannot be guaranteed for slurry with large concentration fluctuations.

Abstract

A slurry separation device, the slurry inlet pipe is located above the coarse screen, the slag outlet of the cyclone separation device is located above the fine screen, the coarse screen and the fine screen are located above the slurry storage tank; the liquid outlet of the cyclone separation device is located Above the middle storage tank, the middle storage tank is located above the slurry storage tank, the bottom of the middle storage tank is equipped with a slurry replenishing pipe, the bottom of the slurry replenishing pipe is located in the slurry storage tank, and the bottom of the slurry replenishing pipe is equipped with a buoy liquid level control device; the slurry storage tank The bottom of the slurry pump is connected to the slurry inlet of the cyclone separation device. The liquid level balance device and the slurry separation device provided by the present invention can realize the automatic balance function of the liquid level by controlling the liquid level of the slurry storage tank by using the middle storage tank and the buoy liquid level control device. The buoy liquid level control device is connected by connecting pins, which is convenient for disassembly, replacement and maintenance.

Description

technical field [0001] The invention relates to the field of mud treatment in the field of environmental protection, in particular to a liquid level balance device and a slurry separation device. Background technique [0002] In the field of sludge or construction mud treatment, it is necessary to realize mud-water separation, river and lake dredging, urban pipe network sludge reduction treatment, tailings dry discharge, urban sewage treatment plant sludge desanding, etc. The requirements for the treated slurry When the discharge standard or recycling standard is met, the solid waste residue is landfilled, incinerated or recycled. [0003] In the previous mud treatment equipment, the adjustment of the slurry flow was by manual monitoring, manual adjustment or ultrasonic liquid level gauge. If the slurry feeding speed is higher than the pumping speed of the slurry pump, the slurry storage tank will overflow. If the slurry feeding speed is lower than the pumping speed of the...
