Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a dual-shaft staggered toothed roller crushing equipment for silicon material crushing. Background Technology

[0002] With the increasing global demand for clean energy, the photovoltaic industry, as an important component of renewable energy, has experienced rapid development. Crystalline silicon, as the main material for photovoltaic cells, is also in high demand. To meet the needs of large-scale production, efficient and reliable silicon material crushing equipment is required to process large quantities of silicon material. The quality of silicon material has a crucial impact on the performance and conversion efficiency of photovoltaic cells. The dual-axis staggered toothed roller crusher uses two rollers with staggered teeth rotating relative to each other to squeeze, shear, and stretch the silicon material, quickly and effectively crushing it into the required particle size, greatly improving crushing efficiency. The dual-axis staggered toothed roller crusher can achieve fine crushing of silicon material, ensuring uniform particle size and regular shape, thereby improving the quality of the silicon material and providing a guarantee for the production of high-performance photovoltaic cells.

[0003] Modern photovoltaic silicon wafer production processes are highly automated. Crushed silicon material is more suitable for feeding and processing by automated equipment. From silicon material production to waste disposal, crushing is a key link connecting upstream raw materials and downstream applications. Its core objective is to match the particle size, shape, and uniformity of materials with process requirements through physical processing, ultimately achieving the industrial production goals of improved efficiency, reduced costs, and controllable quality. In existing technologies, electric motors provide power, and the motors are reduced in speed by a reducer to obtain greater torque. The reduced power is transmitted to the driven shaft through gear transmission or direct-drive worm gear reducer motor, causing relative motion between the blades or teeth on the drive shaft and the driven shaft. However, this crushing method cannot change the degree of crushing. If objects that need fine crushing are coarsely crushed, the resulting volume will be too large, making subsequent operations difficult. Conversely, if objects that need coarse crushing are finely crushed, excessive fine powder will be generated due to over-crushing, wasting crushing energy and requiring additional dust removal equipment, increasing energy consumption and environmental costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a dual-shaft staggered toothed roller crushing device for silicon material, which aims to improve the problem that the existing technology can only crush materials with the same degree of crushing, and cannot change the crushing process, thus reducing the flexibility and practicality of the equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dual-shaft interlaced toothed roller crushing device for silicon material crushing, comprising an inclined shell, the bottom of which is connected to a hollow shell, waterproof shells being fixedly connected to the front and rear ends of the right side of the outer wall of the hollow shell, a support shell being connected to the bottom of the hollow shell, a crushing mechanism being provided on the inner wall of the hollow shell, the crushing mechanism being used to crush the material to different degrees, and a control mechanism being provided on the inner wall of the inclined shell, the control mechanism being used to control the feeding speed;

[0006] The crushing mechanism includes a partition plate, the outer wall of which is fixedly connected to the inner wall of the inclined shell. Baffles are fixedly connected to the front and rear ends of the left side of the outer wall of the partition plate. A power assembly is provided on the inner wall of the waterproof shell. A fine crushing assembly is provided on the left side of the outer wall of the power assembly, and a coarse crushing assembly is provided on the right side of the outer wall of the power assembly.

Rotating components are provided on the left and right sides of the top of the inclined shell. A transmission component is provided on the inner wall of the partition.

[0009] As a further description of the above technical solution:

[0010] The power assembly includes a motor, the outer wall of which is fixedly connected to the inner wall of the waterproof shell, and a rotating shaft is fixedly connected to the output end of the motor.

[0011] As a further description of the above technical solution:

[0012] The coarse crushing assembly includes a crushing roller, the inner wall of which is fixedly connected to the right side of the outer wall of the rotating shaft, and a plurality of crushing blocks are fixedly connected to the outer wall of the crushing roller.

[0013] As a further description of the above technical solution:

[0014] The fine crushing assembly includes a second crushing roller. The inner wall of the second crushing roller is fixedly connected to the left side of the outer wall of the rotating shaft. A second crushing block is fixedly connected to the outer wall of the second crushing roller. Protrusions are fixedly connected to both the left and right sides of the second crushing block.

[0015] As a further description of the above technical solution:

[0016] The rotating assembly includes two rotating columns, the outer walls of which are rotatably connected to the top left and right sides of the inclined shell, and a rotating plate is fixedly connected to the left side of the outer wall of each rotating column.

[0017] As a further description of the above technical solution:

[0018] The transmission assembly includes a second motor, the outer wall of which is fixedly connected to the inner wall of the waterproof shell, and a transmission column is fixedly connected to the output end of the second motor.

[0019] As a further description of the above technical solution:

[0020] The inner wall of the support shell is provided with a collection mechanism, which includes a collection box. The outer wall of the collection box is slidably connected to the front side of the inner wall of the support shell. A fixing plate is fixedly connected to the inner wall of the collection box, and a handle is fixedly connected to the front side of the collection box.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the material is poured into the right side of the partition, the motor is started, and the rotating shaft and the crushing roller work together to crush the material. If a higher degree of crushing is required, the material is poured into the left side of the partition, and the crushing roller, the crushing block, and the protruding block work together to crush the material.

The transmission column then drives the double-rail pulley to rotate. The double-rail pulley pulls the rope and lifts the rotating plate. The rotating plate rotates around the rotating column, reducing the opening of the inclined shell and reducing the material entry speed. This achieves control over the feeding speed and prevents the feeding speed from being too fast, which would lead to excessive workload on the equipment and reduce its service life.

[0042] Working principle: When a lower degree of crushing is required, the material is poured into the right side of the partition 201, and then the motor 2031 is started. The motor 2031 drives the rotating shaft 2032 to rotate, which in turn drives the crushing roller 2041 to rotate. During the rotation, the crushing roller 2041 crosses with the crushing roller 2041 on the other side, and the crushing block 2042 crushes the poured material. When a higher degree of crushing is required, the material is poured into the left side of the partition 201, and the crushing roller 2051 drives the crushing block 2052 to rotate. During the crushing process by the crushing block 2052, the material is further crushed by the protruding blocks 2053 on both sides. This allows for the classification of materials with different degrees of crushing and the simultaneous crushing of two types of materials, thereby improving the practicality of the equipment.

[0043] When the feeding speed needs to be controlled, motor 3051 is started. Motor 3051 drives transmission column 3052 to rotate, which in turn drives double-rail pulley 302 to rotate. During the rotation, double-rail pulley 302 pulls the pull ropes 303 on both sides inward, thereby pulling up the rotating plates 3042 on both sides. This causes the rotating plates 3042 to rotate around the outer wall of rotating column 3041, which reduces the opening size of inclined shell 1 and thus reduces the material entry speed. This achieves control of the feeding speed and prevents the feeding speed from being too fast, which would lead to excessive workload on the equipment and reduce its service life.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
