Crusher with water-jet cutter

Abstract

The invention belongs to the field of mechanical equipment for crushing solid particles in a water environment, and relates to a water jet crusher, which includes a slurry box, a box cover and a collection tank. The box cover, the box cover is equipped with a material inlet, and the collection tank is equipped with a material outlet; the slurry box is equipped with a main shaft, and a number of knife groups are fixed on the main shaft. Each knife group includes several knife bodies, and the adjacent knife bodies are dislocated. Arrangement, one end of the main shaft is connected to the power output device; the inner wall of the slurry box in front and rear of the main shaft is provided with fixed blades, and the fixed blades cooperate with the cutter body. The structure design of the present invention is reasonable. When the cutter body and the fixed blade are combined for crushing and cutting, due to the dislocation arrangement of the adjacent cutter bodies, the contact time of all the cutter bodies and the fixed blade is inconsistent, so resonance is not easy to occur, and because the adjacent cutter bodies do not cut at the same time, The probability of material sticking to the cutter body is reduced, and at the same time, adjacent cutter bodies do not apply force at the same time, which avoids the occurrence of slipping and chipping.

Description

technical field [0001] The invention relates to a water jet crusher, which belongs to the field of mechanical equipment for crushing solid particles in a water environment. Background technique [0002] Most of the raw materials of the crusher are materials with irregular sizes and shapes. Crushing is a process in which external forces are applied to the crushed materials to overcome the cohesive force between the molecules of the materials and split the large materials into several small pieces. At present, part of the crusher is suitable for crushing solid particles in ordinary environments, and the other part is used for crushing solid particles in water environments, and some physical characteristics of solid particles in water environments will change, such as the viscosity of materials, etc. In addition, In the water environment, the crushing knife is prone to slipping during the crushing process. And whether it is under normal circumstances or in a water environment,...

At present, part of the crusher is suitable for crushing solid particles in ordinary environments, and the other part is used for crushing solid particles in water environments, and some physical characteristics of solid particles in water environments will change, such as the viscosity of materials, etc. In addition, In the water environment, the crushing knife is prone to slipping during the crushing process

And whether it is under normal circumstances or in a water environment, the currently used crushing knives are prone to resonance during the crushing process, damaging the machine itself, and prone to chipping, affecting work efficiency and increasing crushing costs
