Description
Technical Field
[0001] This utility model relates to the technical field of self-priming bucket equipment, specifically to a filter device for a self-priming bucket. Background Technology
[0002] Self-priming containers typically refer to containers or devices with self-priming capabilities. Their working principle is based on the siphon principle, which draws liquid by creating negative pressure.
[0003] The structure of self-priming tanks varies in related technologies, mainly depending on their application scenarios and functional designs. However, they typically include a device for creating negative pressure and a pipe for extracting liquid. For example, in a wastewater circulation device for a spray tower, the supernatant formed after the wastewater passes through a three-stage sedimentation tank flows into the clear water tank and then enters the clear water tank through a suction pipe installed at the inlet end of the self-priming tank. By discharging gas or liquid at the outlet end of the self-priming tank, the pressure inside the tank is reduced, creating a negative pressure (low pressure) effect, which draws the liquid in the clear water tank into the self-priming tank through the suction pipe.
[0004] Most existing self-priming tanks can only achieve the purpose of self-priming water, but the recycled water formed after filtration in the clear water tank contains a lot of flocculent matter that cannot be completely settled. It will enter the self-priming tank with the recycled water and then enter the pump body. After long-term use, it will cause wear on the pump impeller and thus affect the service life of the corrosion-resistant pump. To solve the above problems, a filtration device for self-priming tanks is proposed. Utility Model Content
[0005] In view of this, the present invention provides a filtration device for a self-priming pump. The present invention performs primary filtration of the recycled water flowing into the self-priming pump through an inlet filter cylinder, secondary filtration of the recycled water entering the self-priming pump through a second filter screen, primary filtration of the recycled water exiting the self-priming pump through a first filter screen, and secondary filtration of the recycled water exiting the self-priming pump through an outlet filter cylinder. This improves the quality of the inlet and outlet water of the self-priming pump, thereby reducing flocculent matter in the recycled water, reducing wear on the pump impeller, and extending the service life of the corrosion-resistant pump.

[0010] The second tube has a second internal thread at both the front and rear ends, which is used for sealing connection with the second external thread.
[0011] An extension pipe is provided at the outlet end of the inlet filter cartridge.
