Description

Technical Field

[0001] The utility model relates to the field of sewage treatment equipment, in particular to a mobile sewage discharge device. Background Art

[0002] In underground mine production activities, as the mining depth continues to deepen, water seepage and water dripping problems often occur at the work site, affecting the normal production of the mine. Therefore, in order to ensure the smooth progress of production, the seepage and dripping of the mine must be collected and discharged, which requires the installation of a drainage system in the mine. The drainage system includes ditches, water tanks, water pumps and drainage pipes. The inlet and outlet water is generally collected in the water tank through the ditch, and then the water pump discharges the collected water in the water tank to the surface through the pipe. However, due to the particularity of underground production, the collected water in the water tank is usually a sludge mixture formed by mud and water in the mining site. In the subsequent process of discharging the collected water to the surface by the water pump, due to the sludge in the water, it often causes damage to the water pump and blockage of the pipeline, which seriously affects the normal sewage discharge work and the smooth progress of underground production. Therefore, it is necessary to provide a mobile sewage discharge device in combination with the underground mine production environment. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The sewage discharge device provided by the utility model is to place the water tank at the lowest point of the water tank to collect water, use the filter net and the filter partition to perform multiple filtration, separate the sludge and water in the mine sludge mixture to ensure that the sludge is settled at the bottom of the water tank, and the filtered clean water is discharged to the surface through a water pump, which is practical and convenient.

[0012] 2. The sewage discharge device provided by the utility model places the water pump in the water tank instead of the sludge mixture in the water tank, which can protect the water pump from damage during drainage, reduce the occurrence of blockage, and ensure smooth drainage.

[0013] 3. A water level sensor switch is provided in the water tank of the sewage discharge device. When the collected water in the water tank rises to the set height, the water level sensor switch transmits a signal to the controller. The controller receives the signal and starts the water pump to discharge the filtered collected water in the water tank. It is intelligent and efficient.

[0014] 4. A tee is connected to the sewage pipe of the sewage discharge device, and one end of the tee is facing the pump body. When the water pump is working to discharge water, part of the collected water is flushed onto the water pump through the tee to cool it down, preventing the water pump from being damaged by high temperature due to continuous operation, thereby extending the service life of the water pump.

[0015] 5. The sewage discharge device provided by the utility model is provided with a lifting assembly on the top of the water tank to ensure that the mud and water sewage discharge device is movable.
