Description

Technical Field

[0001] This utility model relates to the field of non-metallic mineral processing technology, and in particular to a high-efficiency non-metallic mineral crushing device. Background Technology

[0002] Non-metallic minerals refer to natural mineral resources that are widely used in industry and daily life, such as quartz, feldspar, kaolin, talc, and barite. These minerals not only have important applications in building materials, ceramics, and glass, but also play an indispensable role in industries such as electronics, chemicals, and pharmaceuticals. With the development of modern industry, higher requirements have been placed on the processing precision and efficiency of non-metallic minerals, especially in the field of ultrafine powder materials, where non-metallic minerals need to be pulverized to the micron or even nanometer level to meet the needs of high-performance materials.

[0003] Patent CN221108374U discloses a crushing and processing equipment for non-metallic mineral products. This patent includes a crushing chamber and crushing rollers located inside the crushing chamber and distributed horizontally. Guide plates are fixedly connected to both sides of the outer wall of the crushing chamber. The lower ends of each guide plate are slidably connected to a sliding plate via a first slide rail. A separation chamber is fixedly connected between the lower ends of the two sliding plates. A separation plate is slidably connected between the front and rear sides of the inner wall of the separation chamber via two second slide rails. The patent uses a second cylinder to drive the separation plate to slide to the right along the two second slide rails until the right side of the separation plate slides to the right side of the separation chamber. The coarser materials that do not meet the pulverization requirements and are located at the top of the separation plate also fall down and are collected. This process facilitates the separation of materials that meet the pulverization requirements from those that do not, allowing for the re-pulverization of the materials that do not meet the requirements. However, this patent still has some shortcomings in practical applications. When pulverizing non-metallic mineral products, a single pulverization operation is insufficient to fully meet the pulverization requirements of non-metallic mineral products. It requires repeated manual feeding and pulverization, which is cumbersome. Furthermore, the separation and re-pulverization of materials rely on manual intervention, which not only increases the labor intensity of workers but also reduces pulverization efficiency.

[0004] Therefore, there is an urgent need to provide a non-metallic mineral crushing device that can crush multiple times and achieve high efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of existing non-metallic mineral crushing devices, which have limited single-time crushing effect, require repeated manual feeding for multiple crushing operations, and have low crushing efficiency, this utility model provides a non-metallic mineral crushing device that can crush multiple times and has high crushing efficiency.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a high-efficiency non-metallic mineral crushing device, comprising a support barrel, a symmetrically distributed feed pipe connected and communicated to the top of the support barrel, a first motor installed at the center of the top of the support barrel, a crushing barrel rotatably disposed inside the support barrel, the top of the crushing barrel being connected to the output shaft of the first motor, and the surface of the crushing barrel having several raised textures, a raised ring surrounding the inner wall of the support barrel, a support frame installed at the bottom of the support barrel, an isolation plate hinged to the side of the support frame, a second motor installed inside the support frame, a grinding basin fixed to the top of the support frame, a grinding disc installed inside the grinding basin, the grinding disc being divided into upper and lower sections, the lower disc being fixed on a grinding bench, and the upper disc being located above the lower disc, its top being rotatably connected to the support barrel, and its bottom being connected to the output shaft of the second motor; furthermore, the upper disc having a grinding hole, and the mating surfaces of the upper and lower discs also having orderly raised and recessed grinding teeth.

[0007] Optionally, the top of the grinding disc is provided with symmetrically distributed protrusions, and the protrusions are provided with grooves. A limiting rod is engaged in each groove. The upper end of the limiting rod is provided with a locking hole, and the side of the groove is provided with a convex ball that matches the locking hole. The convex ball is connected to the inner wall of the groove by a spring. The lower end surface of the limiting rod is provided with an external thread, and a cleaning brush for cleaning the grinding disc is installed at its lower end. The cleaning brush is provided with an internal thread that matches the external thread of the limiting rod.

[0008] Optionally, a screw is threadedly provided at the bottom of the crushing barrel, and a stirring blade is provided at the bottom end of the screw.

[0009] Optionally, a baffle is provided on the rear side of the grinding basin.

[0010] Optionally, a detachable isolation net is provided at the top of the feed pipe.

[0011] Optionally, ventilation openings are provided on the isolation plate.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By adopting a two-stage crushing method, the non-metallic minerals can be crushed step by step with a single feeding, ensuring that the material reaches the required particle size, guaranteeing the crushing effect, increasing the overall crushing efficiency, and reducing the overall labor intensity of the workers.

[0013] 2. The automatic cleaning function of the inner wall of the grinding bowl is realized by the cooperation of the limit rod and the cleaning brush. During the operation of the grinding bowl, the cleaning brush rotates with it and continuously contacts the inner wall of the grinding bowl, effectively removing the attached residual materials, preventing blockage or contamination, and ensuring the stable operation of the device.

[0014] 3. By combining the screw and the stirring blades, the material is agitated, making it evenly distributed and gradually moving towards the grinding holes. This significantly improves the efficiency of material entering the grinding holes, reduces material residence time, and speeds up the entire crushing process. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] Example 1: Please refer to Figures 1-4A high-efficiency non-metallic mineral crushing device includes a support barrel 1. The top of the support barrel 1 is connected to and communicates with symmetrically distributed feed pipes 9 for adding non-metallic minerals to be crushed. A detachable isolation net 17 is installed at the top of the feed pipes 9. During the crushing process, fine dust can easily escape from the feed pipes 9, causing air pollution and affecting the operating environment. The isolation net 17 effectively prevents dust leakage and keeps the working area clean. A first motor 2 is installed at the center of the top of the support barrel 1. A crushing barrel 3 is rotatably installed inside the support barrel 1. The top of the crushing barrel 3 is connected to the output shaft of the first motor 2. The crushing barrel 3 has a design that is narrower at the top and wider at the bottom, facilitating the sliding of crushed particles along its surface. The surface of the crushing barrel 3 has several raised grooves. A raised ring 4 is arranged around the inner wall of the support barrel 1. The interaction between the raised ring 4 and the raised grooves on the surface of the crushing barrel 3 generates shearing force, thereby performing preliminary crushing of the non-metallic minerals. The support frame 5 is installed at the bottom of the support barrel 1. An isolation plate 51 is hinged to the rear side of the support frame 5. A ventilation opening 18 is provided on the isolation plate 51. The design of the ventilation opening 18 can enhance the air circulation inside the support frame 5. A second motor 6 is installed inside the support frame 5. A grinding basin 7 is fixed to the top of the support frame 5. A grinding disc 8 is installed inside the grinding basin 7. The grinding disc 8 is divided into upper and lower discs. The lower disc is fixed on the grinding stool, while the upper disc is located above the lower disc. Its top is rotatably connected to the support barrel 1, and its bottom is connected to the output shaft of the second motor 6. In addition, the upper disc has a grinding hole for adding non-metallic minerals that have been pre-crushed. The mating surfaces of the upper and lower discs are also engraved with orderly concave and convex grinding teeth. A baffle 16 is provided on the rear side of the grinding basin 7. During the crushing process, non-metallic minerals may splash due to the centrifugal force generated by the high-speed rotation of the upper and lower discs. The design of the baffle 16 can effectively prevent materials from flying out of the grinding basin 7, avoiding waste and pollution of the working environment.

[0025] When this device is in use, the non-metallic minerals to be crushed enter the support barrel 1 through two feed pipes 9. The first motor 2 starts and drives the crushing barrel 3 to rotate. The material slides down the crushing barrel 3 under the action of gravity. The surface of the crushing barrel 3 is provided with several raised textures, and the inner wall of the support barrel 1 is surrounded by raised rings 4. When the crushing barrel 3 rotates, strong friction and shearing force are generated between the raised rings 4 and the raised textures, thereby performing preliminary crushing of the non-metallic minerals. Since the crushing barrel 3 is designed to be narrow at the top and wide at the bottom, the material that meets the particle size requirements will slide down the surface of the crushing barrel 3 to the bottom. Larger particles that do not meet the particle size requirements will remain in the upper part of the crushing barrel 3 and continue to participate in the crushing process until they meet the particle size requirements before falling down. The material after preliminary crushing falls from the bottom of the crushing barrel 3 to the grinding disc 8. The crushed material then enters the joint surface between the upper and lower discs through the grinding holes of the upper disc. The second motor 6 starts and drives the upper disc to rotate. The relative movement between the upper and lower discs applies a strong grinding force to the material, further crushing the material into finer particles. The crushed material falls into the outer periphery of the grinding basin 7.

[0026] Example 2: Based on Example 1, please refer to... Figure 5 and 6 The grinding disc 8 has symmetrically distributed protrusions on its top. Each protrusion has a groove, and a limiting rod 10 is engaged in each groove. The upper end of the limiting rod 10 has a locking hole, and a convex ball 12 matching the locking hole is slidably arranged on the side of the groove. The convex ball 12 is connected to the inner wall of the groove by a spring 11. The function of the spring 11 is to allow the convex ball 12 to automatically extend and retract to engage or disengage from the locking hole, thereby fixing or disassembling the limiting rod 10. The lower end surface of the limiting rod 10 has an external thread, and a cleaning brush 13 for cleaning the grinding disc 7 is installed at its lower end. The cleaning brush 13 has an internal thread that matches the external thread of the limiting rod 10. Through the combination of the internal and external threads, the cleaning brush 13 can be firmly installed at the lower end of the limiting rod 10.

[0027] When cleaning the grinding basin 7 is required, insert the limiting rod 10 into the groove. At this time, the convex ball 12 automatically springs into the locking hole of the limiting rod 10 under the action of the spring 11, thereby firmly fixing the limiting rod 10 to the protrusion structure. Then, install the cleaning brush 13 at the lower end of the limiting rod 10, and then turn on the second motor 6 to make the upper plate run. During this process, the cleaning brush 13 rotates with the upper plate and continuously contacts the inner wall of the grinding basin 7 to remove the residual material attached to the grinding basin 7 and prevent blockage or contamination. When it is necessary to remove the limiting rod 10, simply press the convex ball 12 manually to disengage it from the locking hole, and the limiting rod 10 can be easily pulled out of the groove.

[0028] Please see Figure 7The bottom of the crushing barrel 3 is threaded with a screw 14. The threaded connection facilitates the installation and disassembly of the screw 14, making maintenance and replacement convenient. The bottom end of the screw 14 is provided with a stirring blade 15. The function of the stirring blade 15 is to stir the material in the grinding disc 8, so that the material enters the grinding hole more evenly, thereby improving the crushing efficiency.

[0029] When the crushing barrel 3 rotates, the screw 14 rotates together with the crushing barrel 3. The stirring blades 15 stir the material by rotating, causing the material to gradually move towards the grinding hole and enter the grinding hole evenly. This process significantly improves the efficiency of material entering the grinding hole and reduces the material residence time, thereby speeding up the entire crushing process.

[0030] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
