[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-3This utility model provides a technical solution: a fine grinding device for preparing raw materials for ceramic wear-resistant materials, including a fine grinding device body 1, a mounting shell 3 on the fine grinding device body 1, and a crushing roller 4, a screening screen 5, a first moving grinding disc 6 and a second moving grinding disc 8 installed sequentially from top to bottom inside the mounting shell 3. The first moving grinding disc 6 and the second moving grinding disc 8 are connected and fixed by connecting rods, so that the first moving grinding disc 6 and the second moving grinding disc 8 can rotate synchronously under the drive of a reduction motor to achieve fine grinding. The upper end of the mounting shell 3 is bent to form a guide plate 305, and a support base 303 is screwed to the bottom of the mounting shell 3. The upper end of the support base 303 is fastened with three superimposed stationary grinding discs 7 by a through screw structure. This structure can be controlled by the guide plate 305. 05. The raw materials introduced by the feeding conveyor belt 2 are guided to the crushing roller 4. The crushing roller 4 is a reverse synchronous driven roller shaft, which can further crush the raw materials and effectively reduce large particles. The crushed raw materials can be screened by the screening screen 5 to remove large particles. At the same time, small particles can be finely crushed by the first moving grinding disc 6 and the second moving grinding disc 8 in sequence. The stationary grinding disc 7 is reliably positioned by the support base 303, so that the stationary grinding disc 7 can work in conjunction with the first moving grinding disc 6 and the second moving grinding disc 8. The mounting shell 3 is equipped with a feeding dust cover 304, and the feeding conveyor belt 2 is set at the side opening of the feeding dust cover 304. The feeding conveyor belt 2 can carry the ceramic wear-resistant material. The raw materials are conveyed into the main body 1 of the fine grinding device. An induced draft fan 11 is installed on the outside of the mounting shell 3. Driven by a motor, the induced draft fan 11 rotates the impeller, causing the exhaust pipe 1103 to extract the dust-laden gas from the feed dust cover 304 to prevent powder from escaping and being wasted. The inlet and outlet ends of the induced draft fan 11 are connected to the exhaust pipe 1103 and the outlet pipe 1101, respectively. The stationary grinding discs 7 have symmetrically arranged conical hole structures at their upper and lower ends. The first moving grinding disc 6 and the second moving grinding disc 8 are engaged between two adjacent stationary grinding discs 7. In this structure, the uppermost stationary grinding disc 7 can be guided through the upper conical hole, while the lowermost stationary grinding disc 7 can be discharged through the lower conical hole. The exhaust pipe 1103 is connected to the feed dust cover 304, and is equipped with... A dust collector 10 is provided to filter the extracted dust for utilization. Simultaneously, the generated high-pressure gas is transported through an exhaust pipe 1101 to an exhaust branch pipe 1102, and then from the exhaust branch pipe 1102 to the arc-shaped pipe 12. The arc-shaped pipe 12 allows the high-pressure gas to be blown through nozzles 1201 onto the sides of the first moving grinding disc 6 and the second moving grinding disc 8, thereby promoting material flow at the first and second moving grinding discs 6 and 8, preventing blockages during grinding, and ensuring a fine grinding effect. The outer side of the mounting shell 3 is also equipped with arc-shaped pipes 12 corresponding to the positions of the first and second moving grinding discs 6 and 8, respectively. The distance between the upper and lower surfaces of the first and second moving grinding discs 6 and 8 and the upper and lower stationary grinding discs 7 gradually decreases.This structure allows the raw materials to be gradually and finely crushed. A discharge conveyor belt 9 is located below the main body 1 of the fine crushing device, and the width of the discharge conveyor belt 9 is greater than the diameter of the opening at the lower end of the stationary grinding disc 7. This structure allows the finally crushed raw materials to fall onto the discharge conveyor belt 9 for transport. Nozzles 1201 are evenly spaced on the inner side of the arc-shaped pipe 12, and exhaust branch pipes 1102 connected to the arc-shaped pipe 12 are attached to the side of the exhaust pipe 1101. The screening screen 5 is installed at an angle inside the mounting shell 3, and a discharge hole 302 is opened on the side of the mounting shell 3 to engage with the lower position of the screening screen 5. A protective cover 301 is welded and fixed to the outer side of the mounting shell 3 at the discharge hole 302. This structure uses a vibrating motor to drive the vibration of the screening screen 5, allowing the screening screen 5 to screen the crushed raw materials, removing large particles that are unsuitable for grinding. The discharge hole 302 is used for discharging large particles, and the protective cover 301 is used for dust prevention during discharge.
[0018] Working Principle: When using this ceramic wear-resistant material preparation raw material fine crushing device, the ceramic wear-resistant material preparation raw material is first initially crushed and then conveyed to the feeding dust cover 304 by the feeding conveyor belt 2. Then, it is guided between the crushing rollers 4 by the guide inclined plate 305. The crushing rollers 4 crush the material to make the material particles more uniform. The blower 11 uses negative pressure to draw the dust-laden gas at the feeding dust cover 304 into the dust collector 10 through the exhaust pipe 1103 for filtration. Then, the clean gas is conveyed to the exhaust branch pipe 1102 through the exhaust pipe 1101, and then to the arc pipe 12. The crushed raw material is screened through the screening screen 5, so that large particles are discharged from the discharge hole 302. The protective cover 301 serves to discharge material and prevent dust. The material falling below the screening screen 5 is guided by the uppermost stationary grinding disc 7 into the space between the first moving grinding disc 6 and the stationary grinding disc 7. Through the cooperation of the first moving grinding disc 6 and the second moving grinding disc 8 with the stationary grinding disc 7, the raw material is gradually finely crushed. The high-pressure gas in the arc-shaped tube 12 is sprayed onto the sides of the first moving grinding disc 6 and the second moving grinding disc 8 through the nozzle 1201 to promote the flow of powder and avoid blockage. The mounting shell 3 supports the stationary grinding disc 7 through the support base 303. Finally, the powder is discharged from the lowermost stationary grinding disc 7 and falls onto the discharge conveyor belt 9, realizing the efficient grinding of ceramic wear-resistant material raw materials by the main body 1 of the fine crushing device, thus completing a series of tasks.
[0019] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
