Description

Technical Field

[0001] This utility model relates to the field of crushing equipment, specifically to a high-quality, long-life silicon crusher. Background Technology

[0002] Silicon crushers are mainly used to process high-hardness silicon-based materials. Their core function is to crush large raw materials to the required particle size to meet different industrial needs. Silicon materials are widely used in semiconductor manufacturing, photovoltaic industry, metallurgy and alloy processing, and construction and building materials industries. Factors affecting the lifespan of silicon crushers include high temperature and vibration caused by overload. Vibration caused by overload is an important factor that reduces the lifespan of the crusher. Therefore, it is necessary to design a high-quality, long-life silicon crusher. Summary of the Invention

[0003] The purpose of this invention is to provide a high-quality, long-life silicon crusher with the advantages of high quality and long life.

[0004] The technical solution adopted is as follows:

[0005] A high-quality, long-life silicon material crusher includes a shell with two crushing rollers rotatably mounted inside. A drive mechanism is located outside the shell, comprising two drive shafts connected to the crushing rollers by a torque sensor. A controller is located outside the shell, connected to both the torque sensor and the drive mechanism. A feed pipe is located at the upper end of the shell, with a uniform feeding mechanism at the upper end of the feed pipe. A discharge port is located at the lower end of the shell.

[0006] Preferably, the lower end of each crushing roller is provided with a dust suction pipe, which extends to the outside of the outer shell and is connected to a dust collection box. The dust collection box is connected to a negative pressure fan, and an air filter is provided between the negative pressure fan and the dust collection box.

[0007] Preferably, the lower end of the discharge port is connected to a first screw feeder.

[0008] Preferably, the uniform feeding mechanism includes a second screw feeder, and the upper end of the second screw feeder is provided with a feed inlet.

[0009] Preferably, the crushing roller is detachably equipped with a roller skin made of tungsten carbide composite material.

[0010] Preferably, each bearing of the crushing roller is provided with an oil cooling mechanism. The oil cooling mechanism includes a housing, which is sleeved on the outside of the bearing. The housing and the shaft are connected by a rotary seal, and the housing is filled with lubricating oil.

[0011] Preferably, the outer surface of the housing is provided with multiple heat dissipation fins.

[0012] Compared to existing technologies, the advantages are:

[0013] 1. This utility model utilizes a uniform feeding mechanism to uniformly feed material into the interior of the outer shell, avoiding overload and vibration caused by excessive feeding. At the same time, the torque sensor transmits torque data to the controller. When the torque exceeds the set value, the drive mechanism stops, preventing damage to the crushing roller due to overload, thereby extending the service life of the silicon crusher.

[0014] 2. This utility model utilizes a negative pressure dust collection mechanism to reduce dust inside the outer casing, reduce dust entering the bearing, reduce bearing wear, and extend service life. Attached Figure Description

[0020] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 4 As shown:

[0021] Example 1: A high-quality, long-life silicon material crusher includes a shell 1, with two crushing rollers 2 rotatably arranged inside the shell 1. A drive mechanism 3 is arranged outside the shell 1. The drive mechanism 3 includes two drive shafts 4. The drive shafts 4 are connected to the crushing rollers 2 by a torque sensor 5. The drive mechanism 3 drives the two crushing rollers 2 to rotate through the drive shafts 4 and the torque sensor 5, thereby crushing the silicon material. The torque sensor 5 monitors the torque of the crushing rollers 2.

[0022] A controller 12 is installed on the outside of the housing 1. The controller 12 is connected to both the torque sensor 5 and the drive mechanism 3. The torque sensor 5 transmits the detected torque data to the controller 12. When the torque exceeds the set threshold, the controller 12 controls the drive mechanism 3 to stop to prevent damage to the crushing roller 2 due to overload.

[0023] The upper end of the outer shell 1 is provided with a feed pipe 13, the upper end of the feed pipe 13 is provided with a uniform feeding mechanism 14, and the lower end of the outer shell 1 is provided with a discharge port 15. The uniform feeding mechanism 14 uniformly conveys the silicon material into the outer shell 1, avoiding overload and vibration caused by excessive feeding, which can lead to mechanical fatigue and shorten the life of the crusher.

[0024] Example 2: A high-quality, long-life silicon material crusher includes a housing 1. Two crushing rollers 2 are rotatably arranged inside the housing 1. The crushing rollers 2 are detachably equipped with tungsten carbide composite material roller skins. A drive mechanism 3 is arranged outside the housing 1. The drive mechanism 3 includes two drive shafts 4. The drive shafts 4 are connected to the crushing rollers 2 by a torque sensor 5. The drive mechanism 3 drives the two crushing rollers 2 to rotate through the drive shafts 4 and the torque sensor 5, thereby crushing the silicon material. The torque sensor 5 monitors the torque of the crushing rollers 2.

[0025] The bearings of the crushing roller 2 are all equipped with an oil cooling mechanism. The oil cooling mechanism includes a housing 6, which is sleeved on the outside of the bearing. The housing 6 is connected to the shaft by a rotary seal. The housing 6 is filled with lubricating oil, and multiple heat dissipation fins 7 are provided on the outside of the housing 6. The oil cooling mechanism dissipates heat and lubricates the bearings that are prone to high temperatures, thus extending the service life of the bearings.

[0026] The lower end of each crushing roller 2 is equipped with a dust suction pipe 8, which extends to the outside of the outer shell 1 and is connected to a dust collection box 9. The dust collection box 9 is connected to a negative pressure fan 10, and an air filter element 11 is installed between the negative pressure fan 10 and the dust collection box 9. The negative pressure dust suction mechanism reduces the dust inside the outer shell 1, reduces the dust entering the bearing, reduces the wear of the bearing, and extends its service life.

[0027] A controller 12 is installed on the outside of the housing 1. The controller 12 is connected to both the torque sensor 5 and the drive mechanism 3. The torque sensor 5 transmits the detected torque data to the controller 12. When the torque exceeds the set threshold, the controller 12 controls the drive mechanism 3 to stop to prevent damage to the crushing roller 2 due to overload.

[0028] The upper end of the outer shell 1 is provided with a feed pipe 13, and the upper end of the feed pipe 13 is provided with a uniform feeding mechanism 14. The uniform feeding mechanism 14 includes a second screw feeder. The upper end of the second screw feeder is provided with a feed port, and the lower end of the outer shell 1 is provided with a discharge port 15. The lower end of the discharge port 15 is connected to a first screw feeder 16. The uniform feeding mechanism 14 uniformly conveys silicon material into the outer shell 1, avoiding overload and vibration caused by excessive feeding, which can lead to mechanical fatigue and shorten the life of the crusher.

[0029] The working principle is as follows: The controller 12 controls the drive mechanism 3 to start, thereby driving the two crushing rollers 2, starting the uniform feeding mechanism 14, the first spiral feeder 16 and the negative pressure fan 10. The uniform feeding mechanism 14 feeds material evenly into the interior of the outer shell 1, avoiding overload and vibration caused by excessive feeding. During the crushing process of the crushing rollers 2, the torque sensor 5 transmits the torque data to the controller 12. When the torque exceeds the set value, the drive mechanism 3 stops to avoid damage to the crushing rollers 2 due to overload, thereby extending the service life of the silicon crusher. The negative pressure dust collection mechanism reduces dust inside the outer shell 1, reduces dust entering the bearing, reduces bearing wear, and extends service life. The crushed silicon material is discharged from the first spiral feeder 16.

[0030] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
