The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in figure 1, a pump body with a filtering structure, a pump body 1 is fixedly installed on a base, a pipeline 2 is fixedly connected to the inlet end of the pump body 1 in the horizontal direction, a position close to the inlet end of the pump body 1 in the pipeline 2 is connected with a filter screen 3 through a vibration mechanism 8, and a first separating mechanism 5 and a second separating mechanism 6 are sequentially arranged at the inlet end of the pipeline 2 from outside to inside. After the pump body 1 is opened, in sewage got into pipeline 2 in the sewage pond, and in order through first partition mechanism 5, second partition mechanism 6 and filter screen 3 carry out the operation and filter to sewage, make and get into in the pump body 1 sewage impurity particle size meet the requirements, prevent because impurity particle is too big to cause the harm to the blade, prevent simultaneously that the granule from excessively causing the blade card pause phenomenon, guarantee that sewage smoothly pumps.

In this embodiment, as shown in fig. 2 and 3, the vibration mechanism 8 includes a plurality of sliding rods 83, the number of the sliding rods 83 is preferably four, the four sliding rods 83 are respectively parallel to the central line of the pipeline 2, the four sliding rods are uniformly arranged in the pipeline in the circumferential direction, two ends of each sliding rod 83 are respectively fixed on the pipeline 2 through a support 81, each sliding rod 83 is slidably sleeved with a sliding sleeve 84, the sliding rods 83 are respectively sleeved with springs 82 at two sides of the sliding sleeve 84, one end of each spring 82 is fixedly connected with the sliding sleeve 84, and the other end of each spring is fixedly connected with the support. The structure of the filter screen 3 is as shown in fig. 5, the filter screen 3 is fixed in the fixing ring 32, four avoiding notches 31 corresponding to the sliding sleeve 84 are formed in the outer ring of the fixing ring 32 in an inwards concave manner, the sliding sleeve 84 is arranged in the avoiding notches 31, the sliding sleeve 84 and the fixing ring 32 are fixedly connected in a welding or other manner, and the structure can ensure that the gap between the filter screen 3 and the inner wall of the pipeline 2 is small. Since the sliding rod 83 is provided with the springs 82 at two ends of the sliding sleeve 84, the bracket 81 functions as a spring seat, and only a force is applied to the filter screen 3 along the axial direction of the pipe 2, for example, as shown in fig. 1, a rightward force is applied to the filter screen 3, at this time, the spring 82 at the right side of the sliding sleeve 84 is compressed and deformed, the spring 82 at the left side is stretched and deformed, and when the force is removed, the spring 82 at the right side which is compressed and the spring 82 at the left side which is stretched rebound, respectively, and the filter screen 3 moves back. Because the springs are arranged at the two ends of the sliding sleeve respectively, the spring 82 can generate elastic deformation repeatedly, namely the spring 82 can compress and stretch repeatedly, and the filter screen 3 vibrates repeatedly, so that impurities attached to the spring drop, and the passing performance of the filter screen is ensured. Or the spring 82 is a compression spring, namely the springs 82 on the two sides of the sliding sleeve 84 are respectively in a compression deformation state after assembly, and the reciprocating vibration of the filter screen 3 can be realized. In this embodiment, after the pump body 1 is opened, sewage gives the filter screen 3 a large impact force, which is an acting force for reciprocating vibration of the spring, and after the pump body 1 is stopped, the impact force disappears, and at this time, the filter screen 3 starts reciprocating vibration.

In this embodiment, for the adnexed impurity on the quick detach filter screen, and in order to collect the impurity that the filter screen dropped, the filter screen adopts the slope mode of setting up, and its incline direction leans out for 3 tops of filter screen. Slide bar 83 avoids the 2 lowest end settings of pipeline, the discharge gate that corresponds with this filter screen 3 is seted up in filter screen 3 front side position department to 2 pipe wall lowest ends of pipeline, and this discharge gate can be dismantled and be equipped with collecting vessel 7. And after the pump body stops running, the impurities attached to the filter screen drop into the collecting barrel to be collected. The slide bar 83 avoids the topmost end of the pipeline 2 to be arranged, the topmost end of the pipe wall of the pipeline 2 is provided with a water inlet corresponding to the filter screen at the position of the rear side of the filter screen 3, the water inlet corresponds to a water inlet joint 4, and the water inlet joint 4 is matched with a plug. When the filter screen 3 needs to be thoroughly cleaned, the water inlet connector 4 is plugged, the water inlet connector 4 is connected with the high-pressure water inlet pipe, high-pressure water is sprayed to the filter screen 3 through the water inlet connector 4, the filter screen is reversely washed, impurities attached to the filter screen are washed clean, and the passing performance of the filter screen is guaranteed.

Because can deposit in the sewage pond and have the clod, still have debris such as branch, because suction is very big, cause the filter screen harm when avoiding great hard piece to strike filter screen 3, in this embodiment, as shown in fig. 4, first segmentation mechanism 5 and second segmentation mechanism 6 include a plurality of bar cutters that set up side by side respectively, the cutting edge of bar cutter sets up outwards, and bar cutter arrangement direction is perpendicular in first segmentation mechanism 5 and the bar cutter arrangement direction in the second segmentation mechanism. During the suction operation, first segmentation mechanism 5 and second segmentation mechanism 6 at first play preliminary filtering function, prevent that branch, the great hard silt piece of volume from impacting filter screen 3 in getting into pipeline 2, and secondly this first segmentation mechanism 5 and second segmentation mechanism 6 can be cut apart into little volume structure with the great mud piece of volume, then sewage in pipeline transportation process, and the mud piece can be dissolved and form mud in sewage, finally through the output of pump body 1.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
