Description

Controllable mud discharging device of scanning formula

Technical Field

The utility model relates to the technical field of sludge pump control, in particular to a scanning type controllable sludge discharge device.

Background

Because the sludge discharged from the sedimentation tank and the sludge water in the filter washing tank produced by the waterworks are rich in organic matters, algae, heavy metals, gravels and the like, the treatment is improper, and the environment is easily polluted. Therefore, the effluent water of the waterworks is generally treated by the working procedures of regulation, concentration, dehydration and the like. Wherein, in the concentration tank, the discharged sludge and water are separated by gravity, the supernatant is discharged, and the sludge sinks. After being scraped to a mud groove by a mud scraper, the sludge is pumped to a balance tank by a mud pump and then enters a dewatering machine room. When the mud in the mud groove is continuously pumped out by the mud discharging pipe, the fluidity of the mud is weaker than that of water, after a part of the mud is discharged, the mud around the mud groove does not have time to flow into the mud groove, the water flows into the mud groove and is pumped away, the resistance for pumping the water is smaller than that for pumping the mud, the water is pumped all the time in the later period, the solid content rate is unstable, and the mud pumping efficiency is low.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provides a scanning type controllable sludge discharge device.

The technical scheme for realizing the purpose of the utility model is as follows: the utility model provides a scanning type controllable sludge discharge device which is provided with two sludge discharge pumps with parallel pipelines, wherein the pipelines of the two sludge discharge pumps are both connected with four pneumatic valves in parallel; four equal pipelines of pneumatic valve are connected in parallel to have two mud pipes, the both ends of mud pump are equipped with the service valve, pneumatic valve tube coupling the one end of mud pump to and tube coupling the one end of mud pipe all is connected with manual valve.

The maintenance valve is a normally open maintenance valve.

The manual valve is a normally open manual valve.

After the technical scheme is adopted, the utility model has the following positive effects:

the automatic scanning type sludge pumping device is simple in structure, and the sludge is discharged in a scanning manner by sequentially starting and stopping the plurality of pneumatic valves in turn (not all the pneumatic valves are started and stopped simultaneously), so that the sludge in the sludge tank is quickly sucked out, and the aim of automatically scanning type sludge pumping is fulfilled. The mud sucking machine can achieve the effects of quick response, short mud sucking time, high mud sucking efficiency, stable suction, higher solid content of the pumped mud, more uniform mud quality and cleaner suction. The problems that water is easily pumped, the solid content of mud is low, the mud suction time is long, the efficiency is low, and the mud in a mud tank cannot be sucked cleanly in the traditional mud suction mode are solved.
