Novel sewage pump

Abstract

The utility model provides a novel sewage pump, and belongs to the technical field of water pumps. The problem that an existing sewage pump is low in sealing performance is solved. The novel sewage pump comprises a pump body and a water inlet filter cover connected to the bottom of the pump body, a sealing device is arranged between the water inlet filter cover and the pump body and comprises a sealing body inserted between the pump body and the water inlet filter cover, the upper end and the lower end of the sealing body are each provided with a sealing clamping part extending outwards, and the longitudinal section of each sealing clamping part is of a rectangular structure. The outer rings at the upper and lower ends of the water inlet filter cover radially extend to form connecting rings. The sealing structure has the advantage that the sealing performance is improved.

Description

Technical Field

[0001] The utility model belongs to the technical field of water pumps, and relates to a sewage pump, in particular to a new type of sewage pump. Background Art

[0002] There is a lack of a sealing structure between the water inlet filter cover at the bottom of the existing sewage pump and the pump body, resulting in fine impurities entering the pump body through the gap between the two, affecting the service life of the internal structure of the pump body. Summary of the Invention

[0003] The purpose of the utility model is to provide a new type of sewage pump with improved sealing performance for the above problems existing in the prior art.

[0004] The purpose of the utility model can be achieved by the following technical solutions: a new type of sewage pump, including a pump body and a water inlet filter cover connected to the bottom of the pump body, characterized in that a sealing device is provided between the water inlet filter cover and the pump body, and the sealing device includes a sealing body inserted between the pump body and the water inlet filter cover. Both upper and lower ends of the sealing body have sealing clamping parts extending outward, the longitudinal section of the sealing clamping part is a rectangular structure, and connecting rings are formed by radially extending the outer circumferences of the upper and lower ends of the water inlet filter cover.

[0005] In the above new type of sewage pump, both left and right ends of the sealing clamping part have a number of inwardly recessed elastic grooves, and the outer edge of the sealing clamping part is provided with rounded corners.

[0006] In the above new type of sewage pump, the connecting ring and the pump body are connected by screws.

[0007] Compared with the prior art, the new type of sewage pump has the advantage of improving the sealing performance. Brief Description of the Drawings

[0008] Figure 1 is a perspective view of the new type of sewage pump.

[0009] Figure 2 is a partial cross-sectional view of the new type of sewage pump.

[0010] In the figure, 1, pump body; 2, water inlet filter cover; 3, sealing body; 4, sealing clamping part; 5, connecting ring; 6, screw; 7, elastic groove. Detailed Description of the Embodiments

[0011] The following are specific embodiments of the utility model in combination with the drawings, and the technical solutions of the utility model will be further described, but the utility model is not limited to these embodiments.

[0012] Such as Figure 1 , Figure 2As shown, the novel sewage pump comprises a pump body 1 and a water inlet filter cover 2 connected to the bottom of the pump body 1, a sealing device is provided between the water inlet filter cover 2 and the pump body 1, the sealing device comprises a sealing body 3 inserted between the pump body 1 and the water inlet filter cover 2, the upper and lower ends of the sealing body 3 both have a sealing clamping part 4 extending outward, the longitudinal section of the sealing clamping part 4 is a rectangular structure, the upper and lower ends of the outer ring of the water inlet filter cover 2 radially extend outward to form a connecting ring 5, and the sealing device connection is more stably provided by the clamping arrangement of the sealing body 3 and the sealing clamping part 4.

[0013] To elaborate further, the left and right ends of the sealing clamping part 4 are provided with a plurality of inwardly recessed elastic grooves 7, and the outer edge of the sealing clamping part 4 is provided with rounded corners. The provision of the elastic grooves 7 makes the installation more stable, and the sealing clamping part 4 undergoes a certain deformation under pressure during installation, so that the position of the sealing clamping part 4 between the two elastic grooves 7 can be squeezed, more closely fitting the corresponding wall surface, and having better sealing performance.

[0014] Preferably, the connecting ring 5 and the pump body 1 are connected via screws 6 .

[0015] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0016] Although the terms such as pump body 1, water inlet filter housing 2, sealing body 3, sealing clamping part 4, connecting ring 5, screw 6, elastic groove 7 are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
