Description

Technical Field

[0001] This utility model belongs to the field of silicon carbide processing technology, specifically, it relates to a silicon carbide raw material crushing and processing device. Background Technology

[0002] Silicon carbide is a crystal with high hardness, strong cutting ability, stable chemical properties, and good thermal conductivity. It has a wide range of applications, mainly as an abrasive and refractory material. Abrasive particles are usually used in a very narrow particle size range. Jaw crushers or impact crushers are often used to crush them, and then a grinder is used to grind them into the required particle size.

[0003] In existing technologies, the crushing and processing of silicon carbide raw materials generates a large amount of dust. Due to the high hardness of silicon carbide, the intense friction and collision between particles during crushing causes fine dust particles to fly around, seriously polluting the air quality in the workshop, endangering the health of operators, and causing occupational health problems such as respiratory diseases. Moreover, the dust dispersion also causes material loss and increases production costs. Furthermore, the mechanical work and frictional heat generation during crushing are significant. Without effective heat dissipation measures, the temperature in the crushing area rises rapidly. Under high-temperature environments, especially when the raw material contains impurities, silicon carbide is prone to chemical reactions, changing its own physicochemical properties, resulting in a decline in product quality. This makes it impossible to meet the stringent requirements for raw material quality in high-precision fields such as electronic-grade silicon carbide. Therefore, this utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a silicon carbide raw material crushing and processing device that can overcome the above problems or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: a silicon carbide raw material crushing and processing device, including a water tank, with support rods vertically fixedly connected to the four corners of the water tank, and further including: a top plate, fixedly connected to the upper ends of the four support rods; a mounting plate, connected to two support rods located on the same side; two crushing chambers used in conjunction, symmetrically arranged between the two mounting plates, with the two crushing chambers rotatably connected to the adjacent mounting plates respectively, and the mounting plates having openings for use with the crushing chambers; a hydraulic telescopic rod, rotatably connected to the lower end of the mounting plate, with the telescopic end of the hydraulic telescopic rod rotatably connected to the bottom of the crushing chamber on the same side; a lifting cylinder, fixedly connected to the top plate; an impact hammer, located at the lower end of the top plate and fixedly connected to the telescopic end of the lifting cylinder; and spray pipes, equidistantly fixedly connected to both sides of the top plate, with the spray nozzles of the spray pipes angled downwards towards the crushing chamber for conveying water from the water tank to the conveying assembly of the spray pipe, which is installed on the water tank.

[0006] Furthermore, the conveying assembly includes a suction cylinder, a second tension spring, a piston rod with a piston, and a suction pipe. The suction cylinder is fixedly connected at equal intervals to both sides of the upper end of the water tank. The lower end of the second tension spring is fixedly connected to the bottom of the suction cylinder. The piston rod is slidably connected inside the suction cylinder, and its bottom is fixedly connected to the upper end of the second tension spring. The upper end of the piston rod is fixedly connected to a mounting plate. The mounting plate is slidably connected to two support rods on the same side. A one-way valve is provided in both the inlet and outlet of the suction cylinder. The suction pipe is connected to the inlet of the suction cylinder. The end of the suction pipe away from the suction cylinder extends downward into the water tank. The inlet of the spray pipe is connected to the outlet of the suction cylinder.

[0007] To further improve the uniformity of silicon carbide crushing and reduce the adhesion of silicon carbide to the inner wall of the crushing chamber, two first tension springs are symmetrically fixedly connected to the lower end of the mounting plate. The lower end of the first tension springs is fixedly connected to the upper end of the water tank. Fixing columns are symmetrically fixedly connected to both sides of the top plate near the mounting plate.

[0008] Furthermore, it also includes a collection filter box, which is located below the middle of the two crushing chambers, and the water tank is provided with a slide rail that works in conjunction with the collection filter box.

[0009] To ensure the collection filter box is securely positioned on the water tank and to prevent displacement caused by vibration from the mounting plate impacting the fixing column, a first magnetic plate is embedded in the collection filter box near the side wall of the water tank, and a second magnetic plate that magnetically attracts the first magnetic plate is embedded in the water tank.

[0010] To facilitate the removal of gravel and dust that fall from the silicon carbide into the water and into the collection filter box, thus preventing the suction pipe from being blocked, two filter plates are symmetrically arranged on both sides of the collection filter box in the pool, and the suction pipe is located on the side of the filter plate away from the collection filter box.

[0011] After adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: This utility model cleverly utilizes the impact force of the impact hammer during the crushing process to drive the suction cylinder to pump water and automatically spray water to the crushing area through the spray pipe. This design can not only effectively suppress dust generation and prevent a large amount of dust from drifting to the outside world, protecting the surrounding environment and reducing the harm of dust to the respiratory health of operators, but also effectively control the heat generated by mechanical work and particle friction during crushing, preventing the temperature from being too high. In particular, when there are impurities in the raw materials, it can prevent the silicon carbide chemical reaction caused by high temperature, ensuring that the performance of silicon carbide is not damaged, guaranteeing product quality, and laying the foundation for subsequent high-quality silicon carbide applications.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0023] Example 1:

[0024] Reference Figures 1-7A silicon carbide raw material crushing and processing device includes a water tank 1, with support rods 2 vertically fixedly connected to each of the four corners of the water tank 1. It also includes: a top plate 3 fixedly connected to the upper ends of the four support rods 2; a mounting plate 201 connected to two support rods 2 on the same side; two cooperating crushing chambers 5 symmetrically arranged between the two mounting plates 201, with each crushing chamber 5 rotatably connected to the adjacent mounting plate 201; and openings on the mounting plates 201 for cooperation with the crushing chambers 5; and a hydraulic telescopic rod 2. 02, Rotatably connected to the lower end of the mounting plate 201, the telescopic end of the hydraulic telescopic rod 202 is rotatably connected to the bottom of the crushing chamber 5 on the same side; Lifting cylinder 301 is fixedly connected to the top plate 3; Impact hammer 302 is set at the lower end of the top plate 3 and is fixedly connected to the telescopic end of the lifting cylinder 301; Spray pipe 404 is fixedly connected at equal intervals to both sides of the top plate 3, the spray nozzle of the spray pipe 404 faces downwards towards the crushing chamber 5 to transport water in the water tank 1 to the conveying assembly of the spray pipe 404, which is installed on the water tank 1.

[0025] The conveying assembly includes a suction cylinder 4, a second tension spring 401, a piston rod 402 with a piston, and a suction pipe 403. The suction cylinder 4 is fixedly connected to both sides of the upper end of the water tank 1 at equal distances. The lower end of the second tension spring 401 is fixedly connected to the bottom of the suction cylinder 4. The piston rod 402 is slidably connected inside the suction cylinder 4, and its bottom is fixedly connected to the upper end of the second tension spring 401. The upper end of the piston rod 402 is fixedly connected to the mounting plate 201. The mounting plate 201 is slidably connected to two support rods 2 on the same side. One-way valves are provided in the inlet and outlet of the suction cylinder 4. The suction pipe 403 is connected to the inlet of the suction cylinder 4. The end of the suction pipe 403 away from the suction cylinder 4 extends downward into the water tank 1. The inlet of the spray pipe 404 is connected to the outlet of the suction cylinder 4.

[0026] It also includes a collection filter box 101, which is located in the lower position between the two crushing chambers 5, and a slide rail is provided on the water tank 1 to cooperate with the collection filter box 101.

[0027] When silicon carbide raw materials need to be crushed for subsequent grinding, the pre-treated silicon carbide raw materials can be placed into the crushing chamber 5. After adding a certain amount of silicon carbide raw materials, the lifting cylinder 301 can be activated. The lifting cylinder 301 will drive the impact hammer 302 to move up and down, reciprocatingly hammering and crushing the silicon carbide raw materials in the crushing chamber 5. When the impact hammer 302 impacts and crushes the silicon carbide raw materials downward, the mounting plate 201 will overcome the elasticity of the second tension spring 401 under the action of the impact force, causing the piston rod 402 to compress the water in the suction cylinder 4 downward. Then, the water drawn from the water tank 1 through the suction pipe 403 in the suction cylinder 4 will be transported. Water is sprayed into the spray pipe 404, and then sprayed through the spray nozzle onto the silicon carbide raw material, the impact hammer 302, and the crushing chamber 5. This not only reduces dust generated during crushing, preventing large amounts of dust from drifting to the outside world and affecting the environment and the health of workers, thus improving the environmental friendliness of the device, but also prevents the temperature from rising due to friction between silicon carbide particles and between particles and the crushing equipment during the crushing process, which could affect the performance of silicon carbide. For example, the presence of some impurities may trigger a chemical reaction in silicon carbide. Water spraying can cool the silicon carbide, preventing the temperature from getting too high and effectively ensuring the quality of silicon carbide.

[0028] After the silicon carbide raw material is crushed, the hydraulic telescopic rod 202 can be activated to drive the crushing chamber 5 to rotate downwards. Then, the crushed silicon carbide in the crushing chamber 5 will fall into the collection filter box 101 for temporary storage.

[0029] It should be noted that, in order to ensure that the two crushing chambers 5 used in conjunction can move up and down synchronously, such as... Figure 7 As shown, the two mounting plates 201 can be fixedly connected by a connecting rod, thereby ensuring that the two crushing chambers 5 can move upward synchronously.

[0030] Example 2:

[0031] Reference Figures 1-7 A silicon carbide raw material crushing and processing device is basically the same as that in Example 1, but further: two first tension springs 203 are symmetrically fixedly connected to the lower end of the mounting plate 201, the lower end of the first tension springs 203 is fixedly connected to the upper end of the water tank 1, and fixed columns 204 are symmetrically fixedly connected to both sides of the top plate 3 near the mounting plate 201.

[0032] When the impact hammer 302 moves upward, the second tension spring 401 can move upward quickly with the cooperation of the first tension spring 203, so that the mounting plate 201 hits the fixed column 204. Then, under the action of vibration, the silicon carbide in the crushing chamber 5 will fall into the cavities between the large silicon carbide, while the large silicon carbide cannot enter the cavities between the small silicon carbide. Therefore, the small silicon carbide will accumulate at the bottom, while the large silicon carbide will remain at the top. This allows the impact hammer 302 to fully impact and crush the larger silicon carbide, which can not only improve the uniformity of silicon carbide crushing, but also improve the crushing efficiency to a certain extent. At the same time, under the action of vibration, the adhesion of silicon carbide to the inner wall of the crushing chamber 5 can also be reduced, so that the crushed silicon carbide can be discharged into the collection filter box 101 more fully.

[0033] Example 3:

[0034] Reference Figures 1-7 A silicon carbide raw material crushing and processing device is basically the same as that in Example 2, but with a further improvement: a first magnetic plate 103 is embedded in the collection filter box 101 near the side wall of the water tank 1, and a second magnetic plate 104 is embedded in the water tank 1 and magnetically attracted to the first magnetic plate 103. Through the cooperation of the first magnetic plate 103 and the second magnetic plate 104, the collection filter box 101 can be stably positioned on the water tank 1, avoiding the vibration caused by the mounting plate 201 moving upward and hitting the fixing column 204, which would cause the collection filter box 101 to shift and thus affect the subsequent collection effect of crushed silicon carbide.

[0035] Two filter plates 102 are symmetrically arranged on both sides of the collection filter box 101 in the water tank 1. The suction pipe 403 is located on the side of the filter plate 102 away from the collection filter box 101. The arrangement of the two filter plates 102 can block the gravel and dust that fall from the silicon carbide into the collection filter box 101 and fall into the water, so as to avoid clogging the suction pipe 403 and thus affecting the water spray volume of the spray pipe 404, effectively ensuring the stability of the suction cylinder 4 in pumping water.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
