Description

Technical Field

[0001] The invention belongs to the technical field of grinding equipment, and in particular relates to a high-energy air flow mill with a pressurization structure. Background Art

[0002] All-solid waste cementitious material is a new type of building material obtained by processing industrial waste. This material is not only environmentally friendly, but also has high utilization value. When producing all-solid waste cementitious material, phosphogypsum is one of the important raw materials, which can save costs. However, since phosphogypsum mainly comes from industrial production processes such as phosphate fertilizer plants, it is a waste with large emissions and difficult to handle. It is usually necessary to use grinding methods to comprehensively utilize phosphogypsum.

[0003] The air flow mill is a device that uses high-speed airflow to perform ultra-fine grinding of materials. The high-speed rotating airflow causes the materials to continuously rotate, collide and rub in the airflow, thereby achieving the crushing effect of phosphogypsum. It can not only crush phosphogypsum and improve the fineness and uniformity of the product, but also ensure that the original properties of the material are not destroyed, thus meeting the high quality requirements for powder materials in industrial production.

[0004] When using the current air flow mill, the air flow it outputs lacks sufficient air pressure support, which weakens the impact force between the abrasive and the workpiece, resulting in a slower grinding speed and longer processing time. It also affects the particle size uniformity and physical properties of the powder, reducing the overall quality of the product. Therefore, it needs to be improved and optimized.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 7 As shown, an embodiment of the present invention provides a high-energy airflow mill with a supercharging structure, comprising a base 1 and a fixed plate 2, the top of the base 1 is fixedly mounted with the fixed plate 2, a grinding chamber 3 is fixedly mounted inside the fixed plate 2, a first ventilation pipe 4 is fixedly mounted on the outer wall of the grinding chamber 3, a main airflow pipe 5 is fixedly mounted on the inner wall of the grinding chamber 3, and the first ventilation pipe 4 and the main airflow pipe 5 are connected to each other;

[0031] A fixed seat 7 is fixedly installed on the top of the base 1, and a rotating disk 10 is rotatably installed on the top of the fixed seat 7. The top of the rotating disk 10 is rotatably connected to the grinding chamber 3. The left and right sides of the inner wall of the rotating disk 10 are fixedly installed with pressurized air flow pipes 12. The front, back, left and right sides of the fixed seat 7 are all fixedly installed with booster chambers 15, and the tops of the four groups of booster chambers 15 penetrate to the top of the fixed seat 7. One end of the booster chamber 15 is fixedly installed with an air delivery pipe 16, and the top of the air delivery pipe 16 is fixedly installed with an air intake valve 21. An air outlet valve 24 is fixedly installed on the inner wall of the pressure chamber 15, and the air supply pipe 16 and the boost chamber 15 are connected to each other through the air outlet valve 24. A second ventilation pipe 13 is fixedly installed on the top of the air inlet valve 21, and a piston rod 17 is movably installed inside the air supply pipe 16. One end of the piston rod 17 is rotatably connected to a connecting rod 18, and the other end of the connecting rod 18 is rotatably connected to a driving block 19. A second motor 20 is fixedly installed inside the fixed seat 7, and the output shaft of the second motor 20 is fixedly connected to the driving block 19.

[0032] When the material needs to be ground, the staff puts the material inside the hopper 37 and then starts the conveying motor 40. At this time, the auger 39 rotates, so that the material is conveyed to the inside of the grinding bin 3 through the feed pipe 38, and the external air pump conveys the air flow to the inside of the first ventilation pipe 4 through the first air inlet 6 and sprays it out from the main air flow pipe 5, so that the material is blown upward and further ground in the grinding bin 3. During the grinding, the external air pump conveys the air to the inside of the second ventilation pipe 13 through the booster bin 15, and When the air pressure inside the second ventilation pipe 13 increases, the first plug 22 moves downward along the air inlet valve 21, allowing the gas to enter the air delivery pipe 16 and enter the booster chamber 15 through the air outlet valve 24. At this time, the left and right groups of booster chambers 15 perform normal air supply operations through the pressurized air flow pipe 12, and the tops of the booster chambers 15 on the front and rear sides are blocked by the rotating disk 10, so that the internal gas of the booster chamber 15 is compressed. During the compression, the second motor 20 operates to drive the driving block 19 to rotate, and the rotation of the driving block 19 is connected to the connecting rod 18. The piston rod 17 is driven to translate inside the air pipe 16, and the displacement of the piston rod 17 draws air from the inlet valve 21 into the air pipe 16, and is filled into the boosting chamber 15 by the outlet valve 24 to perform auxiliary boosting. This method can shorten the boosting time and increase the density of air compression. It is worth noting that at this time, the inlet valve 21 cooperates with the first plug 22 and the first spring 23 to allow air to enter the air pipe 16 in one direction, while the outlet valve 24 cooperates with the second plug 25 and the second The cooperation of the spring 26 ensures that the air inside the air pipe 16 can only enter the inside of the boosting chamber 15 in one direction to prevent gas loss. After the air inside the boosting chamber 15 is compressed, the operation of the first motor 8 drives the gear 9 to rotate, and the gear 9 drives the rotating disk 10 to rotate through the teeth 11, so that the pressurized air flow pipes 12 on the left and right sides rotate to the front and rear sides. At this time, the boosting chambers 15 on the front and rear sides will spray out the pressurized gas inside from the pressurized air flow pipes 12, and at this time, the left and right groups of boosting chambers 15 begin to pressurize the gas to ensure uninterrupted airflow.

[0033] By setting up four groups of booster chambers 15 in the front, back, left and right directions, when the second motor 20 is operated to drive the piston rod 17 to perform piston movement inside the air pipe 16, so that two groups of booster chambers 15 perform airflow supply operations, the other two groups of booster chambers 15 will compress the gas inside the booster chamber 15 through the piston movement of the piston rod 17. When the pressurized airflow pipe 12 and the booster chamber 15 are aligned, the compressed air can increase the contact pressure between the airflow grinding material and the surface of the processed material. The airflow speed after boosting is faster, and the number of impacts on the surface of the processed material is greater, which can significantly reduce the processing time. This not only improves production efficiency, but also reduces production costs. More importantly, it makes the grinding effect of the material better and the grinding more thorough.

A shell 34 is fixedly installed on the front and rear sides of the material storage box 27, and a transmission rod 35 is rotatably installed inside the shell 34. A driving motor 36 is fixedly installed on the outer wall of the material storage box 27, and the output shaft of the driving motor 36 is fixedly connected to the second plug 25.

[0036] After the material is ground inside the grinding bin 3, it will be conveyed to the inside of the storage box 27 through the conveying pipe 28. At this time, the driving motor 36 operates to drive the transmission rod 35 to rotate. The rotation of the transmission rod 35 drives the moving block 32 abutting against it to move up and down along the limit groove 31. When the moving block 32 moves, the moving block 32 is always abutted against the transmission rod 35 through the return spring 33 to ensure the stability of the vibration of the screen plate 29. The vibration of the screen plate 29 will screen the material to prevent unqualified material from being collected.

[0037] The material is conveyed to the storage box 27 through the conveying pipe 28, and the transmission rod 35 is rotated by the operation of the driving motor 36, and the conveying pipe 28 is driven by the moving block 32 to vibrate up and down along the limit groove 31 to screen the material.

[0039] The staff starts the conveying motor 40, and the auger 39 rotates. The material will be evenly conveyed to the inside of the grinding bin 3 by the auger 39, so that the material is conveyed to the inside of the grinding bin 3 through the feed pipe 38, so as to achieve uniform feeding.

[0040] The conveying motor 40 is operated to rotate the auger 39, and the material in the hopper 37 is further conveyed to the grinding bin 3 through the feed pipe 38. Compared with the traditional device, the device ensures the stability of the material distribution and flow state in the grinding bin 3 through stable and uniform feeding, avoids the problem of poor grinding effect caused by material accumulation, improves production efficiency, and ultimately ensures the consistency and high quality of the product.

[0041] Among them, a first air inlet 6 is fixedly provided on the outer wall of the first ventilation pipe 4, and a second air inlet 14 is fixedly installed on the top of the fixing seat 7. The second air inlet 14 and the boosting chamber 15 are connected to each other.

[0043] Among them, a first motor 8 is fixedly installed on the top of the fixed seat 7, and a gear 9 is fixedly installed on the output shaft of the first motor 8. The gear 9 is rotatably installed on the top of the fixed seat 7. The outer wall of the rotating disk 10 is provided with teeth 11, and the teeth 11 and the gear 9 are meshed with each other.

[0044] After the air inside the boost chamber 15 is compressed, the operation of the first motor 8 drives the gear 9 to rotate, and the gear 9 drives the rotating disk 10 to rotate through the teeth 11, so that the pressurized air flow pipes 12 on the left and right sides rotate to the front and rear sides.

[0048] The air outlet valve 24 can only allow the air in the air delivery pipe 16 to enter the pressurizing chamber 15 in one direction through the cooperation of the second plug 25 and the second spring 26 inside the air outlet valve 24 .

[0049] The left and right groups of booster chambers 15 and the pressurized air flow pipe 12 are connected to each other, and the tops of the front and rear groups of booster chambers 15 are blocked by the rotating disk 10 .

[0050] When the booster chambers 15 on the left and right sides discharge the air, the front and rear groups of booster chambers 15 compress the air. As the rotating disk 10 rotates, the booster chambers 15 on the left and right sides perform compression operations, while the front and rear booster chambers 15 discharge the compressed air.

[0052] The rotation of the transmission rod 35 drives the moving block 32 abutting against the transmission rod 35 to move up and down along the limiting groove 31 .

[0053] Working principle and usage process:

[0054] When the material needs to be ground, the staff puts the material inside the hopper 37 and then starts the conveying motor 40. At this time, the auger 39 rotates, so that the material is conveyed to the inside of the grinding bin 3 through the feed pipe 38, and the external air pump conveys the air flow to the inside of the first ventilation pipe 4 through the first air inlet 6 and sprays it out from the main air flow pipe 5, so that the material is blown upward and further ground in the grinding bin 3. During the grinding, the external air pump conveys the air to the inside of the second ventilation pipe 13 through the booster bin 15, and When the air pressure inside the second ventilation pipe 13 increases, the first plug 22 moves downward along the air inlet valve 21, allowing the gas to enter the air delivery pipe 16 and enter the booster chamber 15 through the air outlet valve 24. At this time, the left and right groups of booster chambers 15 perform normal air supply operations through the pressurized air flow pipe 12, and the tops of the booster chambers 15 on the front and rear sides are blocked by the rotating disk 10, so that the internal gas of the booster chamber 15 is compressed. During the compression, the second motor 20 operates to drive the driving block 19 to rotate, and the rotation of the driving block 19 is connected to the connecting rod 18. The piston rod 17 is driven to translate inside the air pipe 16, and the displacement of the piston rod 17 draws air from the inlet valve 21 into the air pipe 16, and is filled into the boosting chamber 15 by the outlet valve 24 to perform auxiliary boosting. This method can shorten the boosting time and increase the density of air compression. It is worth noting that at this time, the inlet valve 21 cooperates with the first plug 22 and the first spring 23 to allow air to enter the air pipe 16 in one direction, while the outlet valve 24 cooperates with the second plug 25 and the second The cooperation of the spring 26 ensures that the air inside the air pipe 16 can only enter the inside of the boosting chamber 15 in one direction to prevent gas loss. After the air inside the boosting chamber 15 is compressed, the operation of the first motor 8 drives the gear 9 to rotate, and the gear 9 drives the rotating disk 10 to rotate through the teeth 11, so that the pressurized air flow pipes 12 on the left and right sides rotate to the front and rear sides. At this time, the boosting chambers 15 on the front and rear sides will spray out the pressurized gas inside from the pressurized air flow pipes 12, and at this time, the left and right groups of boosting chambers 15 begin to pressurize the gas to ensure uninterrupted airflow.

[0055] After the material is ground inside the grinding bin 3, it will be conveyed to the inside of the storage box 27 through the conveying pipe 28. At this time, the driving motor 36 operates to drive the transmission rod 35 to rotate. The rotation of the transmission rod 35 drives the moving block 32 abutting against it to move up and down along the limit groove 31. When the moving block 32 moves, the moving block 32 is always abutted against the transmission rod 35 through the return spring 33 to ensure the stability of the vibration of the screen plate 29. The vibration of the screen plate 29 will screen the material to prevent unqualified material from being collected.
