Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-4, a dredge pump with impurity filtering function, includes pump inlet 1, and 1 fixed surface of pump inlet installs interface 2, and the mounting hole has been seted up to interface 2 side surface, and movable mounting has bolt 3 in the mounting hole, and interface 2 passes through nut 4 with bolt 3 to be fixed, and 3 surfaces of bolt are provided with prevents stifled filter equipment.

Further, prevent stifled filter equipment and include filter 5, filter 5 is the cylinder structure, and filter 5 is fixed through articulated with bolt 3.

Set up filter equipment at the pump mouth, prevent to block up because of silt too much leads to the pump mouth in the pond, influence work efficiency, the later stage of being convenient for is washd and is maintained in 4 installations of accessible nut and dismantlement.

Further, filter hole 501 has been seted up on a surface of filter 5, filter hole 501 all arrays at a surface of filter 5, filter hole 501 inner wall has been seted up spout 502, spout 502 bottom fixed mounting has spring 503, spring 503 one end fixed mounting has slider 504, a slider 504 fixed surface installs clearance net 505, clearance net 505 movable mounting is at filter hole 501 inner wall.

Sludge enters the pump body through the filter holes 501, the cleaning net 505 is extruded inwards under the suction action of the sludge discharge pump, if the filter holes 501 are blocked by the sludge, the cleaning net 505 drives the cleaning net 505 to be ejected out of the filter holes 501 through the elastic force of the spring 503, and the blocked filter holes 501 are dredged.

Further, the cleaning net 505 is made of stainless steel, one end of the cleaning net 505 is in a conical structure, and a blade 506 is fixedly mounted at one end of the cleaning net 505.

The cleaning mesh 505 is pushed against the sludge in the filter holes 501, the sludge is cut by the blade 506, the sludge is further dredged, and larger impurities are filtered by the cleaning mesh 505.

Furthermore, a wear-resistant layer 507 is fixedly arranged on one surface of the filter plate 5, and the wear-resistant layer 507 is made of rubber.

The sludge is prevented from being mixed with hard stones or glass to damage the surface of the device.

Furthermore, a filter screen 6 is fixedly arranged on one surface of the filter plate 5, and the diameter of the mesh of the filter screen 6 is smaller than that of the filter holes 501.

After the cleaning web 505 has been filtered, it is further filtered.

The working principle is as follows:

mud passes through the filtration hole 501 and gets into the pump body, because of the suction effect of dredge pump, clearance net 505 is inwards extruded, if filter hole 501 is blockked up by mud, clearance net 505 will drive clearance net 505 to filter hole 501 hole outer top through the elasticity of spring 503, will filter the outside top of mud in the hole 501, thereby the mediation is blockked up filters hole 501, and when clearance net 505 outwards pushed up, through blade 506 cutting mud, further dredge mud, and filter great impurity through clearance net 505, the installation of accessible nut 4 and dismantlement, be convenient for later stage washing and maintenance.
