In order to achieve the above object, the utility model provides a following technical scheme:

a sewage pump shell comprises a pump shell body, wherein two ends of the pump shell body are respectively connected with a water inlet pipe and a water outlet pipe; the pump shell comprises a pump shell body and is characterized in that a front cover plate of the pump shell body is provided with guide vanes, a plurality of guide vanes are arranged on the guide vanes at intervals in a rotating mode along the circumferential direction, a water feeding channel formed by surrounding of the guide vanes along the direction towards a water outlet pipe is sequentially reduced, the rotating direction of the guide vanes is the same as the direction of rotation of a pump impeller, and the height of the guide vanes is increased from the lowest value to the maximum value along the direction of a guide vane height curve and then is reduced to the lowest value.

As a further aspect of the present invention: the top of the pump shell body is installed through a plurality of screws.

As a further aspect of the present invention: one side of the pump shell body is provided with an outlet flange (8).

As a further aspect of the present invention: a sewage pump comprising a pump housing as claimed in any one of the preceding claims, said pump housing being mounted on the sewage pump.

Compared with the prior art, the beneficial effects of the utility model are that:

the guide vane with the same rotation direction as the pump impeller is arranged, the height of the guide vane changes along the height curve of the guide vane, the guide vane changes from the minimum to the maximum at the beginning and then changes from the maximum to the minimum at the tail, and the fiber in the liquid in the pump shell body can be prevented from being wound on the guide vane due to the height change. Thereby realized the promotion to pump efficiency, also strengthened the ability of passing through granule and long fiber in the pump case body simultaneously.

Fig. 3 is a top view of the present invention.

Notations for reference numerals: the pump casing comprises a pump casing body 1, a front cover plate 2, guide vanes 3, a pump impeller steering direction 4, a medium flow direction 5, a guide vane height curve 6, screws 7 and an outlet flange 8.

Detailed Description

The present invention will be described in detail with reference to the following embodiments, wherein like or similar elements are designated by like reference numerals throughout the drawings or description, and wherein the shape, thickness or height of the various elements may be expanded or reduced in practical applications. The embodiments of the present invention are provided only for illustration, and not for limiting the scope of the present invention. Any obvious and obvious modifications or alterations to the present invention can be made without departing from the spirit and scope of the present invention.

Referring to fig. 1 to 3, in an embodiment of the present invention, a pump case of a sewage pump includes a pump case body 1, wherein two ends of the pump case body 1 are respectively connected to a water inlet pipe and a water outlet pipe; the pump shell comprises a pump shell body 1 and is characterized in that a front cover plate 2 of the pump shell body 1 is provided with guide vanes 3, a plurality of guide vanes 3 are arranged on the guide vanes 3 at intervals along the circumferential direction in a rotating mode, a water feeding channel formed by surrounding of the guide vanes 3 along the direction towards a water outlet pipe is sequentially reduced, the rotating direction of the guide vanes 3 is the same as the direction of a pump impeller steering direction 4, and the height of the guide vanes 3 is increased from the lowest value to the maximum value along the direction of a guide vane height curve 6 and then is reduced to the lowest value.

In the present embodiment, the top of the pump casing body 1 is mounted by a plurality of screws 7.

Preferably, one side of the pump housing body 1 is an outlet flange 8. Facilitating flange mounting of the pump housing body 1.

The working principle is as follows: the guide vanes 3 which have the same rotating direction as the rotating direction 4 of the pump impeller are arranged on the front cover plate 2 of the pump shell body 1, so that fibers or impurities in liquid in the pump shell body 1 are accelerated to be pumped out of the pump shell body 1 along the flowing direction 5 of a medium, meanwhile, the rotating direction 4 of the pump impeller is the same as the flowing direction 5 of the medium, partial vortex in the pump shell of the pump shell body 1 can be recovered by coupling the rotating direction 4 of the pump impeller and the rotating impeller of the pump, and the efficiency of the pump is improved.
