Detailed Description
To facilitate an understanding of the present invention by those skilled in the art, specific embodiments thereof are described below with reference to the accompanying drawings.
As shown in fig. 1 to 3, the utility model provides a water pumping device with a filtering and cleaning function, which comprises a water tank 1 and a water pump 14, wherein a clamping groove 13 is formed in the water tank 1, and a filter screen 12 is detachably fixed in the clamping groove 13. The filter screen 12 divides the water tank 1 into two parts, one part is a sewage area connected with a water inlet described below, the other part is a water purification area connected with a water outlet described below, and sewage in the sewage area is filtered by the filter screen 12 to become purified water in the water purification area so as to be used by the water supply pump 14.
The water tank is characterized in that a large opening is formed in the top of the water tank 1, a flange cover 8 is detachably arranged on the large opening, a water tank emptying valve 4 and a raw water port are arranged on the flange cover 8, and a raw water pipe 6 is arranged on the raw water port. One end of the raw water pipe 6 is provided with a filter screen cleaning structure, the other end of the raw water pipe is connected with a raw water source, a raw water valve 5 is arranged on the raw water pipe 6, and the raw water valve 5 is arranged outside the water tank 1. Wherein the filter screen cleaning structure is a multi-directional water flow distributor 7
The upper half part of the side wall of the water tank 1 is provided with a water inlet, the water inlet is connected with one end of a water tank inlet pipe 9, and the other end of the water tank inlet pipe 9 is placed at the bottom of a water tank 10 and is immersed in liquid to be extracted.
The lower half part of the side wall of the water tank 1 is provided with a water outlet, the water outlet is connected with one end of a water tank outlet pipe 2, and the other end of the water tank outlet pipe 2 is connected with a water inlet of the water pump 14. And a water outlet of the water pump 14 is provided with a water pump outlet pipe 15, and a water pump emptying valve 11 is arranged on the water pump outlet pipe 15.
Further, in order to avoid impurities from entering the water pump 14, a gap is reserved between the lower edge of the water outlet and the bottom of the water tank 1. Thus, the impurities which are not filtered due to the breakage of the filter screen 12 or other reasons can be deposited on the bottom of the water tank 1 instead of directly entering the water pump 14.
The bottom of the water tank 1 is provided with a drain valve 3, the bottom of the water tank 1 inclines to the position of the drain valve 3, and the drain valve 3 is arranged at the lowest point of the bottom of the water tank 1.
