Since the solid materials are relatively hard, any slight imbalance can cause vibration and noise increase of the equipment. It is a challenge to maintain the stability of the equipment under high-speed operation (not less than 800 r / min) to withstand the impact force and vibration force generated in the breaking process. Therefore, there is an urgent need for a new solution to solve the above problems. SUMMARY
[0003] To solve the above problems, the application discloses a bottom-entry type breaker, which comprises a cylinder body, a breaking mechanism fixedly connected to the middle part of the cylinder body, and a fixed sleeve fixedly connected to the lower middle part of the cylinder body. The breaking mechanism works to break and mix the materials in the cylinder body, and the fixed sleeve supports the breaking mechanism to improve the stability of the breaking mechanism operation.

Through the bearing, the fixed sleeve supports the rotating shaft, reduces the dynamic imbalance caused by the radial runout of the breaking mechanism under stress during operation, and realizes the rotation of the rotating sleeve through the transmission of the rotating hub.
[0005] The side wall of the rotating sleeve is provided with a plurality of screw rods, the screw rods are sleeved with a plurality of lower cutters and distance rings arranged at intervals, the distance between the lower cutters is adjusted according to the replacement of distance rings of different height specifications, so that the height of the materials in the cylinder body is adapted. During the operation of the stirring mechanism, the height of the materials in the cylinder body is different each time, but in the existing scheme, the breaking cutters are mostly fixed, and there are problems in the breaking efficiency and equipment operation. Therefore, the screw rods are provided, and the left and right lower cutters and distance rings are inserted on the screw rods, the distance rings of different heights are replaced according to the liquid level of the materials, so that the lower cutters are uniformly up and down, the height is adjustable, suitable for breaking treatment of materials of different heights, and the dynamic balance stability of the lower cutters can be maintained.
[0006] Preferably, the upper part of the rotating shaft is sleeved with an upper blade and a conical sleeve, the rotating shaft is fixedly connected with a fixed cap, and the upper blade, the conical sleeve and the rotating hub are sequentially fastened downwards. In the process of material falling, the fixed material will hit the upper end of the rotating shaft and cause damage, so the upper blade is arranged to break or throw the material radially, and the conical surface of the conical sleeve can guide the flow and reduce the damage caused by impact.
[0007] Preferably, a sealing ring is arranged in the gap between the fixed sleeve and the rotating sleeve. The sealing ring is made of polytetrafluoroethylene, which avoids entering the fixed sleeve and the rotating sleeve.
[0008] Preferably, a plurality of support legs are fixedly connected to the lower side wall of the cylinder at equal angles. The support legs support the cylinder, and the lower end of the support leg is a fixed plate.
[0009] Preferably, a plurality of spoiler plates are fixedly connected to the inner wall of the cylinder at equal angles. The spoiler plates improve the crushing effect of the crushing mechanism.
[0010] Preferably, the upper and lower side walls of the cylinder are fixedly connected with discharge pipes, respectively. The lower discharge pipe is horizontally arranged to discharge liquid material, and the upper discharge pipe is inclined by 30°, and a screw conveyor is connected to the upper discharge pipe. The solid particles after being broken are floated by the buoyancy of water and collected by the screw conveyor.
[0011] The beneficial effects of the present application are as follows: the screw, a plurality of lower cutters and distance rings are arranged, the distance between the lower cutters is realized by replacing different distance rings, in the actual action process, the height of the cutter is adjusted according to the height of the material liquid surface, and the upper end of the rotating shaft is supported, so that all the lower cutters of the crushing mechanism can be as consistent as possible to withstand the impact force and vibration force generated in the breaking process, and the stable operation of the equipment is ensured.
