Technical Field

[0001] This utility model belongs to the field of mechanical engineering technology, specifically relating to a self-cleaning, anti-clogging sand mill. Background Technology

[0002] A sand mill, also known as a grinding mill or ball mill, is mainly used for fine and ultrafine grinding of materials. It usually achieves material refinement through the mutual friction and impact between the grinding media (such as balls, rods, etc.) inside the rotating cylinder and the material. It is widely used in industries such as chemical, mineral, pigment, paint, pharmaceutical, and food industries to crush various materials such as ores, chemicals, ceramics, and coatings to achieve the required particle size.

[0003] In existing technologies, traditional sand mills often experience blockages at key points such as the feed inlet, screen, and discharge outlet when processing highly viscous, wet, or fibrous materials. Each cleaning may require interrupting the normal production process, leading to increased equipment downtime and affecting production efficiency. In addition, conventional cleaning methods usually require stopping the machine and performing manual cleaning, which is not only time-consuming and labor-intensive, but if the cleaning is not thorough, residual materials may mix into subsequent batches of products, affecting product quality and consistency.

[0026] Example

[0027] Reference Figures 1-4 This is an embodiment of the present invention, which provides a self-cleaning, anti-clogging sand mill, comprising:

[0028] The supporting mechanism 100 includes a frame 101, a sand mill body 102 disposed on the top of the frame 101, and a feed inlet 103 fixedly installed on the outer surface of the sand mill body 102;

[0029] The drive mechanism 200 includes a water tank 201 fixedly installed on the outer surface of the frame 101, a water pump 202 connected to the water tank 201, a water pump 203 connected to one end of the water pump 202, a drain pipe 204 connected to the other end of the water pump 203, a drain outlet 205 fixedly connected to the outer surface of the sand mill body 102, an anti-clogging component 206 for extracting the material processed by the sand mill body 102, and a filter component 207 that cooperates with the anti-clogging component 206 to screen the material.

[0030] The anti-clogging component 206 includes a material extraction pipe 206a connected to the main body 102 of the sand mill, a material extraction pump 206b connected to the material extraction pipe 206a, and a guide pipe 206c connected to the other end of the material extraction pump 206b.

[0031] Specifically, the anti-clogging component 206 also includes a discharge box 206d fixedly installed on the outer surface of the frame 101 and a discharge port 206e connected to the discharge box 206d. The guide pipe 206c is connected to the discharge box 206d.

[0032] When it is necessary to clean the inner cavity of the sand mill body 102, water can be drawn from the water tank 201 by starting the water pump 203 and transported to the inner cavity of the sand mill body 102 through the drain pipe 204 for rinsing. After the cleaning process is completed, the sewage and residual materials can be smoothly discharged through the drain port 205 set on the sand mill body 102.

[0033] Furthermore, the water pump 203 is fixedly installed on the outer surface of the frame 101, and the drain outlet 205 is connected to the main body 102 of the sand mill.

[0034] Furthermore, the filter assembly 207 includes a motor 207a adapted to be installed on the outer surface of the discharge box 206d, and a connecting rod 207b fixedly connected to the output end of the motor 207a via a coupling, the connecting rod 207b penetrating the inner surface of the discharge box 206d.

[0035] Furthermore, the filter assembly 207 also includes blades 207c fixedly connected to the outer surface of the connecting rod 207b, a filter screen 207d disposed on the surface of the discharge box 206d, and a collection box 207e located in the inner cavity of the discharge box 206d.

[0036] When it is necessary to clean the discharge box 206d, the pump 206b can be started. The pump will draw clean water from the inner cavity of the sand mill body 102 and inject it into the discharge box 206d through the guide pipe 206c. The motor 207a will be started, and the motor 207a will drive the connecting rod 207b and the blade 207c to rotate, effectively cleaning the inside of the discharge box 206d and the filter screen 207d.

[0037] Preferably, a bearing sleeve for rotation is installed at the connection between the connecting rod 207b and the discharge box 206d, and the outer surface of the blade 207c is in contact with the inner wall of the discharge box 206d.

[0038] It should be noted that the surface of the discharge box 206d has through holes, and the filter screen 207d is located in the through holes.

[0039] When the main body 102 of the sand mill finishes processing the material, the pump 206b is started. The pump draws the material from the main body 102 of the sand mill through the suction pipe 206a and guides the material into the discharge box 206d through the guide pipe 206c. The motor 207a is started and drives the connecting rod 207b to rotate through the coupling. The blades 207c on the connecting rod rotate accordingly, so that the material can pass through the filter screen 207d in batches for screening. The filtered material falls into the collection box 207e, while the material that fails to pass through the filter screen 207d is collected in the discharge box 206d and finally discharged through the discharge port 206e.

[0040] In operation, the material first enters the main body 102 of the sand mill through the feed inlet 104 to begin processing. After processing, the suction pump 206b is started, which draws the material from the main body 102 of the sand mill through the suction pipe 206a and guides it into the discharge box 206d through the guide pipe 206c. At the same time, the motor 207a is started, which drives the connecting rod 207b to rotate through the coupling. The blades 207c on the connecting rod rotate accordingly, allowing the material to pass through the filter screen 207d in batches for screening. The filtered material falls into the collection box 207e, while the material that fails to pass through the filter screen is temporarily stored in the discharge box 206d and eventually discharged through the discharge port 206e. When it is necessary to clean the inner cavity of the main body 102 of the sand mill, the water pump 203 can be started. It draws water from the water tank 201 and delivers it to the main body 102 of the sand mill through the drain pipe 204. The inner cavity of the mill 102 is rinsed. After cleaning, the wastewater and residual materials can be smoothly discharged through the drain outlet 205 set on the main body of the mill 102, ensuring the cleanliness of the equipment and reducing the risk of blockage caused by residual materials. For cleaning the discharge box 206d, the pump 206b can be started to extract the clean water source in the inner cavity of the main body of the mill 102 and inject it into the discharge box 206d through the guide pipe 206c. Then, the motor 207a is started, and the motor drives the connecting rod 207b and the blade 207c to rotate, effectively cleaning the inside of the discharge box 206d and the filter screen 207d. Since the connecting rod 207b is equipped with a bearing sleeve for rotation at the connection between it and the discharge box 206d, and the outer surface of the blade 207c is in close contact with the inner wall of the discharge box 206d, this not only improves the cleaning efficiency, but also ensures the long-term stable operation of the equipment.

[0041] In summary, through the cooperation of the bearing mechanism 100 and the drive mechanism 200, the self-cleaning process of the sand mill can be effectively completed, and blockage can be effectively prevented, thereby improving production efficiency and reducing maintenance costs caused by material residue or blockage.
