[0024] In the description of the invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood broadly. For example, "connected" may refer to a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the invention based on the specific circumstances.

[0025] See also Figure 1-9 The present invention provides a technical solution: an air flow pulverizing system for medicinal herbs, comprising a feeder 1, wherein the feeder 1 is connected to a pulverizing mechanism 2, the pulverizing mechanism 2 is connected to an air-powder separation system 3, and the air-powder separation system 3 is connected to a filtering mechanism 4.

[0026] The feeder 1 includes a barrel 11, which is provided with an upper cover 12. The herbs to be crushed are poured into the barrel 11. A twin-screw conveying mechanism 13 is provided at the bottom of the barrel 11. The twin-screw conveying mechanism 13 can perform preliminary grinding on the herbs to form herb residue. A venturi feed hopper 14 is connected to the bottom of the twin-screw conveying mechanism 13, and the herb residue falls into the venturi feed hopper 14. A high-pressure air flow inlet pipe 15 is provided below the venturi feed hopper 14, one end of the high-pressure air flow inlet pipe 15 is connected to the crushing mechanism 2, and the other end is connected to the high-pressure air pump 16. Since the gas flowing in the high-pressure air flow inlet pipe 15 forms a negative pressure area, the herb residue in the venturi feed hopper 14 will be sucked in, so that the herb residue enters the crushing mechanism 2.

[0027] The pulverizing mechanism 2 includes a pulverizing chamber 21, in which a plurality of high-pressure nozzles 22 are evenly distributed. A suction pipe 23 is provided above the pulverizing chamber 21, and the suction pipe 23 is connected to the gas-powder separation system 3. The high-pressure nozzles 22 evenly distributed in the pulverizing chamber 2 blow supersonic airflow into the pulverizing chamber 2 to form a high-speed airflow vortex. The high-speed airflow vortex will drive the herbal residue to move at high speed. During the high-speed movement, the slower particles collide violently with the faster particles and are crushed. The centrifugal force generated thereby will cause the large-particle powder to run on the periphery of the pulverizing chamber 2, and the particles that meet the particle size requirements will converge to the center, and are collected and transported to the gas-powder separation system 3 through the suction pipe 23 arranged in the center.

[0028] The gas-powder separation system 3 includes a tank body 31, and a powder collecting cylinder 33 is provided at the bottom of the tank body 31. The solid powder entering the tank body 31 spirally settles and is collected by the powder collecting cylinder 33. A mounting plate 5 is provided in the tank body 31, and a filter bag 51 is installed on the mounting plate 5. The airflow entering the tank body 31 contains ultrafine powder, which is captured on the inner wall of the filter bag 51 by the filter bag 51. A plurality of pairs of telescopic rods 6 are provided around the mounting plate 5. The telescopic rods 6 move alternately to achieve the shaking of the mounting plate 5, thereby driving the filter bag 51 to shake, and the powder is cleaned from the filter bag 51. The cleaned powder finally falls into the powder collecting cylinder 33. A first exhaust pipe 32 is provided on the tank body 31, and a pump is provided on the first exhaust pipe 32. The first exhaust pipe 32 is connected to the filter mechanism 4, and the remaining gas enters the filter mechanism 4 through the suction of the pump.

A first-level fixing ring 54 and a second-level fixing ring 55 are also provided on the filter bag frame 52. The first-level fixing ring 54 is located on the outside of the second-level fixing ring 55. The sides of the first-level fixing ring 54 and the second-level fixing ring 55 are provided with multiple sliding grooves, and the filter bag frame 52 is stuck in the sliding grooves, so that the first-level fixing ring 54 and the second-level fixing ring 55 can achieve linear up and down movement on the filter bag frame 52. A first-level filter layer is provided between the upper fixing ring 53 and the first-level fixing ring 54, and a second-level filter layer is provided between the upper fixing ring 53 and the second-level fixing ring 55. The bottom of the upper fixing ring 53 is provided with two circles of fixing grooves, which are respectively used to fix the first-level filter layer and the second-level filter layer.

[0030] The first-level filter layer includes a first-level filter bag 71, which is provided with a plurality of small holes. The first-level filter bag 71 is passed through a plurality of first positioning lines 72, and the first positioning lines 72 pass through each small hole. The two ends of the first positioning line 72 are respectively wound around the first winder 73 and the second winder 74. There are multiple first winders 73 and second winders 74. The first winder 73 is arranged in the upper fixing ring 53, and the second winder 74 is arranged at the bottom of the filter bag frame 52. The first positioning line 72 passes through the first fixing ring 54 and is fixed in the first fixing ring 54.

[0031] When the first winder 73 is winding, the second winder 74 rotates in the opposite direction, the primary fixing ring 54 moves upward, and the primary filter bag 71 can be folded and retracted; when the second winder 74 is winding, the first winder 73 rotates in the opposite direction, the primary fixing ring 54 moves downward, and the primary filter bag 71 can be unfolded and lowered.

[0032] The secondary filter layer includes a secondary filter bag 81, which is provided with a plurality of small holes. The secondary filter bag 81 is passed through a plurality of second positioning lines 82, which pass through each small hole. The two ends of the second positioning line 82 are respectively wound around the third winder 83 and the fourth winder 84. There are multiple third winders 83 and fourth winders 84. The third winder 83 and the fourth winder 84 are arranged. The third winder 83 is arranged in the upper fixing ring 53, and the fourth winder 84 is arranged at the bottom of the filter bag frame 52. The second positioning line 82 passes through the secondary fixing ring 55 and is fixed in the secondary fixing ring 55.

[0033] When the third winder 83 is winding, the fourth winder 84 rotates in the opposite direction, the secondary fixing ring 55 moves upward, and the secondary filter bag 81 can be folded and retracted; when the fourth winder 84 is winding, the third winder 83 rotates in the opposite direction, the secondary fixing ring 55 moves downward, and the secondary filter bag 81 can be unfolded and lowered.

[0034] The minimum particle size of the medicinal powder that can be filtered by the first-level filter bag 71 is 50 mesh, and the minimum particle size of the medicinal powder that can be filtered by the second-level filter bag 81 is 300 mesh. According to the required particle size of the medicinal powder, the first-level filter bag 71 and the second-level filter bag 81 can be flexibly replaced and used at the same time.
