However, there is a drawback in that the blade continues to rotate together with the blade pieces 8 '...
本考案の目的は、ポンプの吸込口の口径よりも長大な布
帛等の固形物が汚水中に混在していても、容易に切断し
て汚水と共に吸引し得るグラインダーポンプを提供する
ことにある。An object of the present invention is to provide a grinder pump capable of easily cutting and sucking together with sewage even if solid matter such as a cloth having a size larger than the diameter of the suction port of the pump is mixed in the sewage.

翼片よりも肉厚を薄く形成せられているのである。In the grinder pump according to the present invention, a fixed blade is arranged on the inner circumference of an annular guiding lower wall which is guided from a central hole of a suction cover facing a lower surface of a vane plate of a pumping impeller in a pump swirl chamber. A rotating body fitted with the annular guiding lower wall is fixed below the blade, and two blades for cutting, which are guided from the upper portion of the rotating body and whose outer edge faces the fixed blade, are paired on the outer periphery of the rotating body. In the grinder pump that is installed, the guiding lengths of the lower edges of both of the above cutting blades are made asymmetric so that one cutting blade has a lower edge below the rotating body. Reaching the end surface, the other cutting wing piece has a concave stepped portion formed without the lower edge portion reaching the lower end surface of the rotating body, and
The wing piece with a long lower edge is made thinner than the wing piece with a shorter edge.

…６と斜交状に対向させる。In the drawings of the embodiment, 1 is a pump swirl chamber, 2 is a pump impeller housed in the pump swirl chamber 1, and 3 is a pump impeller 2.
The suction cover 4 and the suction cover 3 facing the lower surface of the blade plate.
The central holes 5 are annular guiding walls which are guided down from the central hole 4, and a fixed groove 6 in the form of a vertical groove serving as a suction path is provided on the inner periphery thereof.
A large number of 6 are engraved. Reference numeral 7 denotes a rotating body that fits with the inner circumference of the annular guiding lower wall 5 with a slight gap, and is fixed below the boss so as to rotate together with the pumping impeller 2. Reference numerals 8a and 8b denote two blades for cutting, which are provided on the outer periphery of the rotating body 7 so that the outer edges thereof face the fixed blades 6 ... 6, and the guiding lengths of the lower edges of these blades. The length of the cutting blade 8a becomes asymmetrical due to the difference in length, and the lower edge of one blade 8a for cutting reaches the lower end surface 7a of the rotating body 7, while the lower edge of the blade 8b for cutting has its lower edge. A wing piece that has a concave step portion D that does not reach the lower end surface 7a of the rotating body 7 and has a lower edge portion that has a longer wall thickness than that of the wing piece 8a that has been guided shortly. By forming it thinner than 8b, the weight balance can be retained. 9 ... 9 are arcuate recesses formed in the lower portion of the outer periphery of the rotating body 7 by the protruding portions of the cutting blades 8a, 8b. Further, a spiral groove 10 that winds up in the counter-rotational direction so as to communicate with the arcuate recesses 9 ... 9 into the pump swirl chamber 1 is engraved in the upper portion of the outer periphery of the rotary body 7, and the fixed blades 6 ...
... and 6 in an oblique pattern.

ことになる。When the pump is driven, the rotary body 7 rotates together with the pumping impeller 2, and the solid blades are finely cut by the intersection of the fixed blades 6 ... 6 and the blades 8a, 8b for cutting. The long solid 11 straddling between the wing blades moves in the centrifugal direction due to the resistance difference between the wing blades 8a and 8b having an unbalanced guiding length, and moves from the concave step D to the inside of the annular guiding wall 5. It is sucked into the circumference and crushed finely, and the solid matter after crushing is spiral groove 10 and fixed blade 6 ...
6 is forcibly pushed up by the oblique crossing with 6, and is discharged from the discharge port 12 through the pump swirl chamber 1 together with the pumping.

う利点がある。In the grinder pump of the present invention, the guide length of the lower edge of the blade for cutting has a difference in length, so that a long solid substance straddling a plurality of blades also moves in the centrifugal direction due to the resistance difference. Then, there is an advantage that it is easily sucked into the inner circumference of the annular guiding lower wall from the concave step portion and finely crushed by the intersection of the fixed blade and the blade for cutting.
