Peripheral pump

Abstract

The utility model provides a peripheral pump, and belongs to the technical field of water pumps. The vortex pump solves the problem that due to the fact that an existing vortex pump is lack of a filtering structure, impurities enter the pump to abrade an impeller. The peripheral pump comprises a pump body and a water inlet end arranged at the end of the pump body, the water inlet end is externally connected with a pipeline, a filtering structure is arranged at the water inlet end and between the water inlet end and the pipeline, the filtering structure comprises an outer framework and a filtering disc which is arranged in the middle of the outer framework and integrally formed with the outer framework, and a partition groove is formed between the filtering disc and the outer framework. A plurality of filtering holes are formed in the filtering disc, the longitudinal section of each filtering hole is of a reaming structure, holes with large inner diameters on the filtering holes face the impeller, the filtering disc is sleeved with a filtering net cover, an elastic ring is arranged on the outer ring of the filtering net cover, and the elastic ring is arranged in the partition groove in a sleeved mode and tightened on the peripheral wall of the filtering disc. The filtering device has the advantage of good filtering effect.

Description

Technical Field

[0001] The utility model belongs to the technical field of water pumps and relates to a vortex pump. Background Art

[0002] Currently, the water inlet position of the vortex pump head on the market lacks a filtering structure. Since the water flows through the water inlet end and directly contacts the impeller, if the water flow with impurities enters the pump, it will directly collide with the impeller, which may easily cause damage to the impeller and affect the service life of the pump. Summary of the Invention

[0003] The purpose of the utility model is to provide a vortex pump with a longer service life and improved filtering effect in order to solve the above problems existing in the prior art.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a vortex pump, comprising a pump body and a water inlet end arranged at the end of the pump body, the water inlet end is externally connected to a pipeline, characterized in that a filtering structure is arranged on the water inlet end and between the pipeline, the filtering structure comprises an exoskeleton and a filter disc arranged in the middle of the exoskeleton and integrally formed with the exoskeleton, a partition groove is provided between the filter disc and the exoskeleton, and a plurality of filter holes are provided on the filter disc, the longitudinal section of the filter hole is an expanded hole structure, the hole with a large inner diameter on the filter hole faces the impeller, the filter disc is sleeved with a filter screen cover, the outer ring of the filter screen cover has an elastic ring, and the elastic ring is sleeved in the partition groove and tightened on the outer peripheral wall of the filter disc.

[0005] In the above-mentioned vortex pump, the outer end wall of the outer skeleton is curved.

[0006] In the above-mentioned vortex pump, the outer ring of the outer skeleton has an outwardly protruding positioning ring.

[0007] Compared with the prior art, the vortex pump has the advantage of good filtering effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] In the figure, 1. pump body; 2. water inlet end; 3. pipeline; 4. exoskeleton; 5. filter plate; 6. partition groove; 7. filter hole; 8. elastic ring; 9. positioning ring. DETAILED DESCRIPTION

[0010] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0011] like Figure 1As shown, the vortex pump includes a pump body 1 and a water inlet end 2 arranged at the end of the pump body 1, the water inlet end 2 is connected to the outside of the pipe 3, and a filtering structure is arranged on the water inlet end 2 and between the pipe 3, the filtering structure includes an exoskeleton 4 and a filter disc 5 arranged in the middle of the exoskeleton 4 and integrally formed with the exoskeleton 4, a partition groove 6 is provided between the filter disc 5 and the exoskeleton 4, and a plurality of filter holes 7 are opened on the filter disc 5, the longitudinal section of the filter hole 7 is an expanded hole structure, and the holes with large inner diameters on the filter holes 7 face the impeller, which can achieve slow flow to a certain extent, and a filter screen cover is provided on the filter disc 5, and the outer ring of the filter screen cover has an elastic ring 8, and the elastic ring 8 is sleeved in the partition groove 6 and tightened on the outer peripheral wall of the filter disc 5, and the filter screen cover can be disassembled to block fine particles.

[0012] Preferably, the outer end wall of the outer skeleton 4 is curved.

[0013] To be more specific, the outer ring of the outer skeleton 4 has an outwardly protruding positioning ring 9 to prevent the filter structure from axial displacement.

[0014] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.

[0015] Although this document frequently uses terms such as pump body 1, water inlet end 2, pipeline 3, exoskeleton 4, filter disc 5, partition 6, filter hole 7, elastic ring 8, and positioning ring 9, the use of other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations is contrary to the spirit of the present invention.
