[0012] Wherein, an air guide structure is arranged on the vertical tube, and the air guide structure is used to form a negative pressure inside the vertical tube.

[0013] Furthermore, the air guide structure includes an air pump fixed on the barrel, the input end of the air pump is connected to the vertical cylinder through a first air pipe, one output end of the air pump is connected to the high-pressure pipe through a second air pipe, a third air pipe is provided on the other output end of the air pump, a pressure regulating valve is provided on the third air pipe, an air diffusion pipe is provided in the recoil zone on the barrel, the third air pipe is connected to the air diffusion pipe, and a plurality of exhaust holes are provided on the side wall of the air diffusion pipe facing the filter disc.

[0014] The control method of the high-efficiency non-metallic mineral ultrafine pulverizer of the present invention comprises the following steps:

[0015] S1, driving the main shaft and multiple push plates to rotate through the motor;

[0016] S2, control to start the air pump, so that negative pressure is formed in the vertical cylinder, and high pressure is formed in the recoil area of ​​the high-pressure pipe and the drum;

[0017] S3, the raw materials are introduced into the horizontal cylinder through the feed pipe, and the rotating push plate pushes the raw materials to circulate between the crushing area and the return area.

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0037] like Figures 1 to 3 As shown, the high-efficiency non-metallic mineral ultrafine pulverizer of the present invention comprises a horizontal cylinder 1, the axis of the horizontal cylinder 1 is horizontal, a filling plate 2 is arranged in the horizontal cylinder 1 along the axis direction of the horizontal cylinder 1, and the filling plate 2 divides the internal space of the horizontal cylinder 1 into a left-side crushing zone 3, a right-side return zone 4, an upper-side feeding zone and a lower-side discharging zone, the crushing zone 3 is vertical, the return zone 4 is cylindrical, the feeding zone is inclined downward toward the crushing zone 3, and the discharging zone is inclined downward toward the return zone 4;

[0038] A main shaft 5 is rotatably provided in the return zone 4, and a plurality of push plates 6 are provided on the outer wall of the main shaft 5. A feed pipe 7 for supplying raw materials into the horizontal cylinder 1 is provided on the horizontal cylinder 1. The feed pipe 7 is located at one end of the horizontal cylinder 1, and a discharge structure is provided at the other end of the horizontal cylinder 1.

[0039] In detail, the left side of the internal space of the horizontal cylinder 1 is arc-shaped, and the right side is square. The filling plate 2 divides the internal space of the horizontal cylinder 1 into multiple areas. The side wall of the filling plate 2 facing the crushing area 3 is vertical, and the side wall of the filling plate 2 facing the return area 4 is set to be arc-shaped, and its radius is equal to the radius of the arc on the right side of the inside of the horizontal cylinder 1. Therefore, the main shaft 5 and the push plate 6 can rotate smoothly in the return area 4, and the feeding area and the discharge area on the upper and lower sides of the filling plate 2 are inclined, which can facilitate the flow of raw materials between the crushing area 3 and the return area 4. The feeding pipe 7 is connected to the crushing area 3, and the raw material enters the crushing area 3 through the feeding pipe 7. The raw material in the crushing area 3 naturally rolls down to the return area 4 through the lower discharge area.

[0040] When in use, the external motor provides rotational power to the main shaft 5, and the main shaft 5 drives multiple push plates 6 to perform synchronous circular motion. The raw material is introduced into the horizontal cylinder 1 through the feeding pipe 7, and the push plate 6 drives the raw material to perform centrifugal motion, and the push plate 6 pushes the raw material upward. When the raw material moves to the loading area, the raw material naturally passes through the loading area due to centrifugal force and enters the crushing area 3. The raw material reciprocates on the left and right inner walls of the crushing area 3, thereby crushing the raw material. The raw material in the crushing area 3 falls and re-enters the return area 4 through the lower side discharge area. The rotating push plate 6 will push the raw material upward centrifugally again and repeatedly enter the crushing area 3, thereby realizing continuous and repeated impact and crushing processing of the raw material. Since the raw material reciprocates on the left and right inner walls of the crushing area 3, the raw materials also collide with each other and crush. With the continuous supply of raw materials, the raw material in the horizontal cylinder 1 increases, and the raw material moves toward the unloading structure while impacting and crushing. The crushed raw material is discharged through the unloading structure, thereby realizing multiple and repeated crushing processing of the raw material, and the raw material realizes a continuous crushing processing mode.

[0041] Through the continuous rotation of the main shaft 5 and the plurality of push plates 6, the raw material can be centrifugally moved and continuously flow between the crushing zone 3 and the return zone 4. Since the raw material is impacted and crushed in the crushing zone 3, the raw material can be continuously and repeatedly impacted and crushed by this method. In addition, since the raw material reciprocates and rebounds against the inner wall of the crushing zone 3 in the crushing zone 3, and the raw materials also collide with each other, the crushing effect of the raw material can be greatly improved. Since the raw material is directly accelerated and impacted, the space for crushing the raw material is increased, the amount of raw material crushed is increased, and the crushing efficiency and speed are improved. By adopting the continuous feeding and continuous crushing methods, the raw material is continuously crushed in the crushing zone 3 and the return zone 4. While forming a circular crushing between the zones 4, the raw materials are conveyed in the horizontal cylinder 1, thereby realizing continuous crushing of the raw materials, which greatly improves the production efficiency and output; since the raw materials are circulated and crushed by their own centrifugal force and gravity, the demand for additional energy is reduced. Compared with the traditional crushing method, this design is more energy-efficient, and its structure is simple, and it is extremely convenient to process, assemble, operate, and maintain; in summary, this technical solution effectively solves the problems of low efficiency, high energy consumption, and unsatisfactory crushing effect existing in traditional crushing technology through innovative structural design and working principle, and provides a more efficient, economical and flexible solution for ultrafine grinding of non-metallic minerals.

[0042] like Figure 3 As shown, a high-pressure pipe 8 is rolled on the outer wall of the horizontal cylinder 1, and the high-pressure pipe 8 is connected to the crushing area 3 through a plurality of nozzles 9, and the nozzles 9 are inclined downward.

[0043] In detail, while the raw materials are impacted and crushed in the crushing zone 3, the high-pressure air in the high-pressure pipe 8 will be blown into the crushing zone 3 through multiple nozzles 9, thereby accelerating the impact effect of the raw materials through the airflow, realizing a pneumatic impact method. At the same time, since the nozzles 9 are tilted downward, the airflow discharged from the nozzles 9 can make the air in the crushing zone 3 flow downward, and the air enters the return zone 4 through the lower discharge area and is then pushed to flow upward by multiple push plates 6. The airflow enters the crushing zone 3 again through the upper feeding area, thereby accelerating the circulation flow speed of the raw materials with the help of the airflow, facilitating the transportation of the raw materials, and improving the circulation flow effect of the raw materials between the crushing zone 3 and the return zone 4, avoiding that part of the raw materials only circulate in the return zone 4, resulting in the inability to effectively crush this part of the raw materials. At the same time, the airflow improves the impact efficiency and impact effect between the raw materials in the crushing zone 3, thereby improving the raw material crushing effect.

[0044] like Figure 3 As shown, a reflux pipe 10 is provided on the transverse cylinder 1, and both ends of the reflux pipe 10 are respectively connected to the two ends of the transverse cylinder 1, and the height of the reflux pipe 10 gradually increases along the direction from the feed pipe 7 to the discharge structure.

[0045] In detail, the raw materials with larger particles among the raw materials near the unloading structure position in the horizontal cylinder 1 are centrifugally pushed by the pushing plate 6, and the raw materials are centrifugally entered into the reflux pipe 10. Since the height of the reflux pipe 10 gradually changes, the raw materials naturally roll down in the reflux pipe 10 and move to the end of the horizontal cylinder 1 where the feeding pipe 7 is provided. In this way, the raw materials with larger particles are moved back to the head end of the horizontal cylinder 1 and circulated and crushed again between the crushing zone 3 and the return zone 4 in the horizontal cylinder 1. This can facilitate the thorough crushing of the raw materials and improve the crushing effect.

[0046] like Figure 3 As shown, a plurality of guide plates 11 are arranged in the feed area, the plurality of guide plates 11 are arranged along the axis direction of the transverse cylinder 1 , and the guide plates 11 are inclined relative to the axis of the transverse cylinder 1 .

[0047] In detail, when the raw materials pass through the feeding area and enter the crushing area 3, the guide plate 11 can guide the raw materials so that the raw materials move a small distance toward the unloading structure position in the axial direction of the horizontal cylinder 1. This can help the raw materials to move laterally in the horizontal cylinder 1, thereby avoiding continuous accumulation of raw materials at the head end of the horizontal cylinder 1.

[0048] like Figure 4 As shown, the unloading structure includes a barrel 12 fixed at the end of the horizontal cylinder 1, the barrel 12 is connected to the return zone 4, a filter disc 13 is rotatably provided in the barrel 12, the filter disc 13 is fixedly connected to the main shaft 5, and a partition 14 is transversely arranged in the barrel 12, and the partition 14 divides the internal space of the barrel 12 into a recoil zone on the upper side and a filtration zone on the lower side.

[0049] In detail, the raw materials in the horizontal cylinder 1 can pass through the filter disc 13 corresponding to the filter area on the lower side of the drum 12 to enter the filter area, and the filter disc 13 filters the raw materials. The larger particles of raw materials intercepted by the filter disc 13 can be moved to the head end of the horizontal cylinder 1 through the reflux pipe 10 for repeated crushing. The main shaft 5 will drive the filter disc 13 to rotate, and part of the filter disc 13 corresponding to the filter area will move to the recoil area. The high-pressure air in the recoil area can blow the filter disc 13 in the opposite direction, so that the raw materials blocked on the filter disc 13 fall off, thereby ensuring that the filter disc 13 can filter the raw materials stably for a long time.

[0050] like Figure 4 As shown, a vertical cylinder 15 is provided at the bottom of the drum 12, and a filter bag 16 is provided in the vertical cylinder 15. One end of the filter bag 16 is connected to the filter area, and the other end of the filter bag 16 faces and is used for discharging materials;

[0051] The vertical tube 15 is provided with an air guide structure, and the air guide structure is used to form a negative pressure inside the vertical tube 15 .

[0052] In detail, the air guide structure will form a negative pressure inside the vertical cylinder 15, and the negative pressure will suck the crushed raw materials in the filter area into the filter bag 16. The raw materials in the horizontal cylinder 1 can also use the negative pressure to enter the filter area, thereby helping the raw materials to be discharged. Since there is air flow in the vertical cylinder 15 and the filter bag 16, the air flow will blow the filter bag 16 to shake, which can make the crushed raw materials deposited on the inner wall of the filter bag 16 fall off, so that the raw materials can be naturally discharged through the bottom opening of the filter bag 16.

[0053] Since there is negative pressure inside the vertical cylinder 15, the raw materials discharged from the bottom opening of the filter bag 16 will not be randomly dispersed due to the airflow, which can prevent dust from flying randomly and affecting the environment.

[0054] like Figure 1 As shown, the air guide structure includes an air pump 17 fixed on the barrel 12, the input end of the air pump 17 is connected to the vertical cylinder 15 through a first air pipe 18, one output end of the air pump 17 is connected to the high-pressure pipe 8 through a second air pipe 19, and a third air pipe 20 is provided on the other output end of the air pump 17, and a pressure regulating valve 21 is provided on the third air pipe 20. A diffuser pipe 22 is provided in the recoil zone on the barrel 12, and the third air pipe 20 is connected to the diffuser pipe 22. The diffuser pipe 22 is provided with a plurality of exhaust holes on the side wall facing the filter disc 13.

[0055] In detail, the air pump 17 can extract the air in the vertical cylinder 15 through the first air pipe 18, and the air extracted by the air pump 17 can be discharged into the high-pressure pipe 8 and the diffuser pipe 22 through the second air pipe 19 and the third air pipe 20 respectively. The pressure regulating valve 21 can be used to control the amount of air entering the diffuser pipe 22, so as to ensure that there is sufficient air pressure in the high-pressure pipe 8. The air in the diffuser pipe 22 can be sprayed onto the filter disc 13 through multiple jet holes, so as to perform a backwash treatment on the filter disc 13.

[0056] The air in the horizontal cylinder 1 can enter the filtering area through the corresponding part of the filter disc 13 in the reverse direction, so that the air in the horizontal cylinder 1 can carry the crushed raw materials into the drum 12 to help the raw materials to be discharged quickly.

[0057] The control method of the high-efficiency non-metallic mineral ultrafine pulverizer of the present invention comprises the following steps:

[0058] S1, driving the main shaft 5 and multiple push plates 6 to rotate through the motor;

[0059] S2, control to start the air pump 17, so that negative pressure is formed in the vertical cylinder 15, and high pressure is formed in the recoil area of ​​the high-pressure pipe 8 and the barrel 12;

[0060] S3, the raw material is introduced into the horizontal cylinder 1 through the feed pipe 7, and the pushing plate 6 in the rotating state pushes the raw material to circulate between the crushing area 3 and the return area 4. The raw material in the crushing area 3 performs impact crushing movement, and the impact intensity of the raw material in the horizontal cylinder 1 is adjusted by adjusting the motor speed;

[0061] S4, the high-pressure air in the high-pressure pipe 8 is blown into the crushing area 3 and helps the crushing area 3 to perform a more effective crushing process;

[0062] S5. With the help of the guide plate 11, the raw materials are circulated and crushed in the horizontal cylinder 1 while moving toward the discharge structure;

[0063] S6. The crushed raw materials are discharged through the unloading structure. By adjusting the air flow of the air pump 17, the air flow intensity of the high-pressure pipe 8 spraying into the crushing area 3 through the nozzle 9 is adjusted, and the speed of the air flow carrying the raw materials into the unloading structure is adjusted, thereby adjusting the unloading efficiency.

[0064] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
