Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of sewage tank dredging device. BACKGROUND

[0002] Gold mining enterprises engaged in gold ore mining extract ore from veins. Subsequently, the ore is crushed, ground and beneficiated, etc. process to extract gold from it. This process usually involves complex chemical and physical methods and produces a large amount of industrial wastewater. These industrial wastewater is accumulated in the sewage tank for further treatment and discharge.

[0003] The above-mentioned sewage tank is equipped with a sewage treatment system. After being treated by the sewage treatment system, the flocculent particulate suspended matter carried in the production wastewater gradually deposits and accumulates in the tank. This kind of flocculent particulate suspended matter has poor fluidity and needs to be dredged regularly. In addition, a large amount of sediment also needs to be cleaned regularly after a period of time. If dredging is not timely, it will reduce the effective volume of the sewage tank and directly affect the quality of the discharged water. The traditional dredging method is to suspend the sewage discharge state and then empty the tank water, and then implement mechanical dredging. The main disadvantage of this method is that it affects production and normal operation of the sewage system.

[0004] The Chinese utility model with the authorized publication number CN202810932U discloses an "automatic pumping device for water accumulation in stope pit", which comprises a floating boat, a floating ball liquid level control switch and a submerged sewage pump.

The floating ball of the floating ball liquid level control switch is placed in the water collecting tank, and the floating ball liquid level control switch controls the submerged sewage pump. In use, the floating boat is placed in the water collecting tank, and the submerged pump start-up upper limit water level and the submerged pump shutdown lower limit water level of the floating ball liquid level control switch are adjusted. The floating boat rises and falls with the water level of the water collecting tank. When the floating boat rises with the water level of the water collecting tank to the upper limit water level, the floating ball liquid level control switch automatically opens, and the submerged pump installed on the floating boat starts to work. When the floating boat descends with the water level of the water collecting tank to the lower limit water level, the floating ball liquid level control switch automatically closes, and the submerged pump installed on the floating boat stops working. The device of the utility model automatically pumps water within the set water level range, takes water from the surface layer of the water body in the water collecting tank in the stope pit, ensures normal production, and improves the quality of pumped water. An important feature of the device is that the submerged pump always takes clean water. Although the floating boat of the patent has good floating effect and can be used for water operation and pumping of sewage in the tank, it does not affect production and normal operation of the sewage system, but it is not suitable for cleaning the sediment at the bottom of the tank. In addition, such floating sewage cleaning devices have a problem that the sewage discharge pipeline and the cable for connecting the submerged sewage pump are easily entangled or deformed by sediment under water during movement and operation, which affects the normal operation of the device.
