Description

Technical Field

[0001] This patent relates to the field of silicon carbide grinding technology, specifically a silicon carbide grinding device. Background Technology

[0002] A silicon carbide micron powder grinding device is a device used to grind silicon carbide particles or block materials into fine silicon carbide micron powder particles. These micron powder particles are commonly used in various industrial fields, including the manufacture of ceramics, coatings, refractory materials, abrasives, electronic components, and grinding processes in multiple fields. Existing silicon carbide grinding devices directly put large silicon carbide particles into the grinding cylinder for grinding. However, some of the large silicon carbide particles contain dust and impurities. After crushing, the micronized silicon carbide contains dust, which affects the quality of the micronized powder. Therefore, we propose a silicon carbide grinding device. Utility Model Content

[0020] The present patent is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.

[0021] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This is a schematic diagram of the structure of this patent. A silicon carbide grinding device includes a housing 1. A feed pipe 2 is embedded in the top of the housing 1. A motor is installed on the outer side wall of the housing 1. The rotating shaft of the motor passes through the side wall of the housing 1 and two grinding rollers 3 are fixedly installed. The bottom front end of the grinding rollers 3 is hinged to a swing rod 4 through a rotating shaft. The bottom end of the swing rod 4 is hinged to a connecting plate 5 through a hinge seat. A stirring rod 6 is fixedly installed at the bottom of the connecting plate 5. Limiting parts 7 are provided at both the left and right ends of the stirring rod 6. A filter screen 8 is hinged to the inner side wall of the housing 1. The filter screen 8 is located below the stirring rod 6. Cleaning water is provided inside the housing 1.

[0022] The limiting component 7 is used to limit the movement trajectory of the stirring rod 6, so that it can only move up and down.

[0023] A sealing door 19 is installed on the bottom right side wall of the housing 1. A support block 20 is installed on the left side of the sealing door 19. The top of the support block 20 is attached to the bottom of the filter screen 8. A grinding cylinder 21 is provided on the lower right side of the sealing door 19. A grinding mechanism is provided on the upper side of the grinding cylinder 21.

[0024] The grinding mechanism consists of a mounting plate, which is fixed to the right side of the housing 1. A hydraulic cylinder is mounted on the mounting plate, and a grinding motor is mounted at the bottom of the piston rod of the hydraulic cylinder. A grinding disc is mounted at the bottom of the motor shaft.

[0025] A limiting frame 9 is fixedly installed on the top of the inner side wall of the box 1. The limiting frame 9 is located directly below the feed pipe 2. Triangular plates 10 are integrally formed at both the front and rear ends of the bottom of the limiting frame 9. The two triangular plates 10 are located between the upper sides of the two grinding rollers 3.

[0026] like Figure 1As shown, the placement of the limiting frame 9 and the triangular plate 10 can prevent some of the silicon carbide that falls from the feed pipe 2 from falling from the front and rear ends of the two grinding rollers 3, thus failing to achieve the grinding effect.

[0027] Specifically, a water injection pipe can be embedded in the side wall of the housing 1, and a sealing door is provided on the side wall of the housing 1, with the sealing door corresponding to the position of the filter screen 8.

[0028] The sealed door allows for easy opening to clean residual silicon carbide microparticles from the filter screen 8 into the grinding cylinder 21.

[0029] Specifically, the stirring rod 6 includes a rod body 11, and the side wall of the rod body 11 is provided with an inner arc groove 12, and there are four inner arc grooves 12.

[0030] like Figure 4 As shown, the inner arc groove 12 is designed to facilitate the insertion of the stirring rod 6 into the silicon carbide micro-particles when it moves downwards.

[0031] Specifically, the limiting component 7 includes a mounting plate 13, which is fixedly installed at the end of the stirring rod 6. The outer side of the mounting plate 13 is provided with two mounting grooves, and the mounting grooves are connected to the limiting wheel 14 through a rotating shaft. The inner sidewall of the housing 1 is provided with wheel grooves 15 at both ends, and the limiting wheel 14 is rolled in the wheel grooves 15.

[0032] Specifically, the feed pipe 2 includes a pipe body 16, which is embedded in the top of the box 1. A left plate 17 is fixedly installed on the left end of the inner wall of the pipe body 16, and a right plate 18 is fixedly installed on the right end of the inner wall of the pipe body 16.

[0033] Specifically, both the left plate 17 and the right plate 18 are tilted.

[0034] The left plate 17 and the right plate 18 are designed to prevent large silicon carbide particles from splashing upwards when being ground by the grinding roller 3, and can be shielded by the left plate 17 and the right plate 18.

[0035] Working principle: Cleaning water is injected into the chamber 1 through the water injection pipe on the side wall of the chamber 1, and silicon carbide is injected through the feed pipe 2. Large silicon carbide particles can be ground by two grinding rollers 3, and small powder particles fall onto the filter screen 8. At the same time, the grinding rollers 3 drive the stirring rod 6 to move up and down through the swing rod 4, thereby agitating and cleaning the cleaning water and small powder particles in the chamber 1. After cleaning, the sewage valve at the bottom of the chamber 1 is opened to discharge the sewage. Then the sealing door 19 is opened, and the support block 20 no longer supports the filter screen 8. The filter screen 8 flips down along the right end of the hinge point, so that the silicon carbide on the filter screen 8 falls into the grinding cylinder 21. Then the grinding motor is controlled by the oil cylinder to move downward, and the grinding disc is driven by the grinding motor to grind the small silicon carbide particles in the grinding cylinder 21.

[0036] It should be noted that the device structure and accompanying drawings of this patent mainly describe the principle of this patent. In terms of the technical aspects of this design principle, the setting of the device's power mechanism, power supply system and control system is not fully described. However, those skilled in the art who understand the principle of the above patent can clearly understand the specifics of its power mechanism, power supply system and control system.

[0037] This patented technology involves installing a grinding roller inside a housing. The front end of the grinding roller is hinged to a swing arm via a pivot, and the bottom end of the swing arm is hinged to a connecting plate via a hinge seat. Multiple stirring rods are installed at the bottom of the connecting plate, and a filter screen is installed on the bottom side of the inner wall of the housing. After the grinding roller grinds the large silicon carbide particles, the micro-powder particles fall onto the filter screen. At the same time, the grinding roller drives the stirring rods to move up and down via the swing arm, thereby agitating and cleaning the cleaning water and micro-powder particles inside the housing, removing dust and impurities from the silicon carbide, and ensuring the quality of the micro-powdered silicon carbide.
