Description

Technical Field

[0001] The invention relates to the technical field of crushers, in particular to a bottom-entry crusher. Background Art

[0002] Bottom-entry crushers often break solid materials into solid particles through high-speed rotation of the mixer. Due to the high hardness of solid materials, any slight imbalance may cause increased vibration and noise of the equipment. It is a challenge to maintain the stability of the equipment at high speed (not less than 800r / min) to withstand the impact and vibration generated during the crushing process. Therefore, a new solution is urgently needed to solve the above problems. Summary of the invention

[0003] In order to solve the above problems, the present invention discloses a bottom-entry crusher, comprising a cylinder, a crushing mechanism is fixedly connected to the middle of the cylinder, and a fixed sleeve is fixedly connected to the middle of the lower end of the cylinder. The crushing mechanism works to crush and mix the materials in the cylinder, while the fixed sleeve supports the crushing mechanism and improves the stability of the crushing mechanism operation.

[0004] The crushing mechanism includes a driving motor, which is fixedly connected to a flange structure preset at the lower end of a fixed sleeve, a rotating shaft is fixedly connected to the output end of the driving motor, and the rotating shaft extends upward to the inside of the fixed sleeve, a bearing is fixedly connected to the upper side wall of the rotating shaft, and the outer ring of the bearing cooperates with the inner wall of the fixed sleeve, a rotating hub is fixedly connected to the upper part of the rotating shaft, and the rotating hub is located above the bearing, a rotating sleeve is sleeved on the outer side of the fixed sleeve, and the upper end of the rotating sleeve is fixedly connected to the upper end edge of the rotating hub. The bearing realizes the support of the fixed sleeve to the rotating shaft, and reduces the dynamic balance imbalance caused by radial runout caused by force during the operation of the crushing mechanism; in addition, the rotating shaft rotates, and the rotating sleeve is rotated through the transmission of the rotating hub.

[0005] The side wall of the rotating sleeve is provided with a plurality of screws, and a plurality of lower cutters and distance rings are sleeved on the screws at intervals, so that the spacing of the lower cutters can be adjusted by replacing distance rings of different height specifications, so as to adapt to the height of the material inside the cylinder. During the operation of the stirring mechanism, the height of the material inside the cylinder is different each time, but in the existing schemes, the crushing cutters are mostly fixed, which has problems in crushing efficiency and equipment operation. Therefore, a screw is provided here, and left and right lower cutters and distance rings are interspersed on the screw. According to the liquid level of the material, the distance rings of different heights are replaced, so that the lower cutters are evenly moved up and down, and the heights are adjustable, which is suitable for the crushing of materials of different heights and can maintain its own dynamic balance and stability.

[0006] Preferably, the upper part of the rotating shaft is sleeved with an upper blade and a cone sleeve, and the rotating shaft is fixedly connected with a fixing cap, and the upper blade, cone sleeve and rotating hub are sequentially buckled downward. 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 provided to crush the material or radially throw it away, and the conical surface of the cone sleeve can guide the flow and reduce the damage caused by the impact.

[0007] Preferably, a sealing ring is sleeved in the gap between the fixed sleeve and the lower part of the rotating sleeve. The sealing ring is made of polytetrafluoroethylene to prevent it from entering between 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 a fixing plate is provided at the lower end of the support legs.

[0009] Preferably, the inner wall of the cylinder is fixedly connected with several spoilers at equal angles. The spoilers improve the crushing effect of the crushing mechanism.

[0010] Preferably, the upper and lower side walls of the cylinder are respectively fixedly connected with discharge pipes. The lower discharge pipe is arranged horizontally to discharge the liquid material, while the upper discharge pipe is arranged at an angle of 30°, where a screw conveyor is connected, and the crushed solid particles float due to the buoyancy of the water and are collected by the screw conveyor.

[0011] The beneficial effects of the present invention are as follows: a screw, a plurality of lower cutters and a distance ring are provided, and the spacing of the lower cutters is achieved by replacing different distance rings. In the actual operation process, the height of the cutter is adjusted according to the height of the material liquid level, and the upper end of the rotating shaft is supported, so that all the lower cutters of the crushing mechanism can ensure the same force as much as possible, so that they can withstand the impact force and vibration force generated in the crushing process, and ensure the stable operation of the equipment.
