Description

Technical Field

[0001] This utility model belongs to the field of self-priming pump technology, and specifically relates to a vortex self-priming pump. Background Technology

[0002] Self-priming pumps all adopt an axial return pump body structure. The pump body consists of a suction chamber, a liquid storage chamber, a vortex chamber, a return hole, and a gas-liquid separation chamber. After the pump starts normally, the impeller draws in the liquid stored in the suction chamber and the air in the suction pipe together, and they are completely mixed in the impeller. Under the action of centrifugal force, the liquid carries the gas and flows towards the outer edge of the vortex chamber.

[0003] When a self-priming pump is in use, impurities in the water will remain inside the pump. Over time, this accumulation will not only cause blockages inside the pump but also corrode the inner wall, affecting the performance of the device. Furthermore, the filter of existing self-priming pumps is usually installed inside the pump, making cleaning and maintenance extremely inconvenient for staff. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing a vortex self-priming pump with a filtering effect and an easy-to-clean filter screen.

[0005] The objective of this utility model can be achieved through the following technical solution: A vortex self-priming pump, comprising a pump body and a drive motor, wherein a pump cover is sealed at the front end of the pump motor, and an inlet pipe for water intake and an outlet pipe for water discharge are provided on the pump cover. The pump cover is characterized in that the drive shaft of the drive motor extends into the pump cover and is connected to an impeller assembly; a filter assembly is provided inside the pump cover and between the inlet pipe and the internal cavity; the filter assembly includes a filter sleeve, a movable rod, and a return spring; a slot is provided at the front end of the pump cover for the filter assembly to move; a fixing part is provided inside the pump cover for the movable rod to pass through; the fixing part has several water passage holes for water to pass through; one end of the filter sleeve abuts against the fixing part; a filter screen is provided inside the filter sleeve; and several filter holes are provided on the outer peripheral wall of the filter sleeve.

[0006] In the aforementioned vortex self-priming pump, one end of the movable rod is provided with a pull rod, the other end of the movable rod is provided with a mounting part, one end of the return spring is connected to the mounting part, and the other end of the return spring is connected to the fixed part.

[0007] In the aforementioned vortex self-priming pump, a sealing cover is provided on the pump cover relative to the slot, and a sealing ring for enhancing the seal is provided on the sealing cover.

[0008] In the aforementioned vortex self-priming pump, the impeller assembly consists of two impeller bodies, both of which are mounted on the drive shaft of a drive motor and rotate under the drive of the drive motor.

[0009] Compared with existing technologies, this vortex self-priming pump filters the liquid entering the cavity by installing a filter sleeve between the inlet pipe and the cavity, thus avoiding damage to the impeller and affecting its service life. In addition, the filter sleeve can extend outside the pump cover, making it convenient for staff to clean and maintain it. Attached Figure Description

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figure 1 , Figure 2 As shown, this vortex self-priming pump includes a pump body 1 and a drive motor. A pump cover 2 is sealed at the front end of the pump motor. The pump cover 2 is provided with an inlet pipe 3 for water intake and an outlet pipe 4 for water discharge. The drive shaft of the drive motor extends into the pump cover 2 and is connected to an impeller assembly. A filter assembly 5 is provided inside the pump cover 2, between the inlet pipe 3 and the internal cavity. The filter assembly 5 includes a filter sleeve 6, a movable rod 7, and a return spring 8. The front end of the pump cover 2 has a slot for the filter assembly 5 to move. A fixing part 9 is provided inside the pump cover 2 for the movable rod 7 to pass through. The fixing part 9 has several water passage holes for water to pass through. One end of the filter sleeve 6 abuts against the fixing part 9. A filter screen 10 is provided inside the filter sleeve 6. Several filter holes are provided on the outer peripheral wall of the filter sleeve 6.

[0015] To elaborate further, the liquid enters through the inlet pipe 3, then is filtered through the filter holes on the filter sleeve 6 and the filter screen 10 inside the filter sleeve 6. After filtration, it enters the cavity through the water passage hole of the fixing part 9, and finally flows out through the outlet pipe 4.

[0016] To elaborate further, when it is necessary to clean the internal filter sleeve 6, open the sealing cover 13, pull the lever 11 to compress the return spring 8, and pull the filter sleeve 6 to the outside, so as to facilitate the cleaning of impurities inside the filter sleeve 6. After cleaning is completed, release the lever 11, the return spring 8 will spring back, and the filter sleeve 6 will return to its original position.

[0017] To elaborate further, one end of the movable rod 7 is provided with a pull rod 11, and the other end of the movable rod 7 is provided with a mounting part 12. One end of the return spring 8 is connected to the mounting part 12, and the other end of the return spring 8 is connected to the fixing part 9.

[0018] To elaborate further, a sealing cover 13 is provided on the water pump cover 2 and relative to the slot, and the sealing cover 13 is provided with a sealing ring for strengthening the seal.

[0019] To elaborate further, the impeller assembly consists of two impeller bodies 14, both of which are mounted on the drive shaft of the drive motor and rotate under the drive of the motor. The multi-stage impeller configuration enhances the efficiency of liquid intake, thereby improving the operating efficiency of the water pump.
