Generally, in this type of crushing pump, a rotatable impeller is provided in the flow path, a crushing lattice plate is provided adjacent to one side of the impeller, and a plurality of radial shapes penetrating both sides of the crushing lattice plate are provided. The solid material is crushed between the respective edges of the corresponding impeller and the grid holes of the crushing grid plate, and the crushed solid material is sent through the grid holes. Conventionally, this solid material was compressed and forced into the grid holes at the moment of crushing, so it could return due to elasticity and clog the inner walls of the grid holes at the moment the crushing was completed.

In the present invention, the circumferential width of the lattice holes of the crushing lattice plate is gradually increased from the side facing the impeller at the inlet to the side opposite to the outlet. The circumferential width of the lattice holes increases in the direction in which the material passes through the lattice holes, so even if the solid material after crushing returns due to elasticity, the compressive force between it and the side wall is reduced. The purpose is to make it easier for solids to separate and eliminate clogging.

In addition, "increasing size gradually from the side surface on the impeller side to the side surface on the opposite side" means that the crushed solids gradually increase in size from the side surface on the impeller side, where the crushed edge of the crushed lattice plate is located, to the side surface on the opposite side. This refers to a gradual change in the width of the lattice hole in the direction in which it passes through the hole, and includes shapes that suddenly become larger in stages and shapes that gradually become larger with an incline. Therefore, this also includes the fact that there is no part where the width becomes smaller on the way from the entrance to the exit of the lattice hole.

In the above embodiments, a drive device (not shown)
When actuated, the rotating shaft 25 is rotated through the flange 49.
The rotation of the impeller 17 causes the liquid to be sucked into the suction passage 11 of the suction casing 5, and the liquid is sucked into the suction passage 11 of the suction casing 5.
It passes through the inside and is discharged to the outside from the discharge passage 13.
The solids mixed into the liquid are removed by the cutting blade 37 and the impeller 1.
The solids crushed between the blade portion 35 of the blade 7 and passed through the impeller 17 are further finely crushed between the blade portion 43 and the edges of the lattice holes 65 of the crushing lattice plate 15, and then passed through the lattice holes 65. It passes through and is discharged from the discharge passage 13. When the solid material is crushed between the blade portion 43 and the edge of the grid hole 65, it is compressed and deformed, and the solid material is crushed into the grid hole 6.
The deformation returns within the lattice hole 65 and it is pressed against the inner wall, but since the width of the inner wall of the lattice hole 65 is set larger than the width of the entrance, it will not become clogged, or even if it is clogged, the pressing force will be reduced. It is small and easily detached by the flow of liquid.
