Description

Technical Field

[0001] The utility model relates to the technical field of air flow crushing, in particular to an air flow crusher capable of automatically feeding materials. Background Art

[0002] In the process of pesticide production, the raw materials used need to be crushed so as to facilitate the preparation of different pesticides and achieve the desired drug effect. In the existing process of crushing pesticide raw materials, an air flow crusher is generally used for crushing. The basic principle of the air flow crusher is as follows: after high-pressure compressed air is filtered and dried, it is sprayed into the crushing chamber through multiple nozzles. The materials are repeatedly collided, rubbed and sheared at the intersection of multiple high-pressure air flows and crushed. At the same time, an induced draft fan is also connected to the crushing chamber, and the induced air volume of the induced draft fan is greater than the high-pressure air flow entering the crushing chamber. In this way, a negative pressure environment is formed in the crushing chamber, and the crushed materials flow out of the inside of the crushing chamber under the suction of the induced draft fan.

[0003] The currently disclosed patent: CN220071920U discloses an air flow crusher. The air flow crusher crushes the materials in the inner cavity of the crushing cylinder by starting the air flow crushing device, and blows the materials upward. The rising materials are blocked by the filter screen, so that large particles with poor crushing effect are blocked by the filter screen. Then, the servo motor 1 is started to drive the rotating rod to rotate, and the beating block is driven to beat the filter screen by the rotation of the rotating rod, so as to beat and drop the materials that may block the filter holes of the filter screen, thereby preventing the materials from blocking at the filter holes of the filter screen.

[0004] Based on the above search, the following problems exist when the above patent is used: when the air flow crusher is used, large particles with poor crushing effect are blocked by the filter screen, and the beating block is driven to beat the filter screen by the rotation of the rotating rod, which can prevent the filter holes from being blocked. However, the crusher directly adds materials into the inside of the crushing chamber through the feeding pipe, and the materials directly enter the inside of the crushing chamber without spreading out. A large amount of materials gather together, reducing the contact area with the air flow, and further affecting the crushing effect of the materials. Summary of the Utility Model

[0005] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide an air flow crusher capable of automatically feeding materials, which can solve the problem that the materials directly enter the inside of the crushing chamber without spreading out, a large amount of materials gather together, reducing the contact area with the air flow, and further affecting the crushing effect of the materials.

[0006] To achieve the above object, the utility model provides the following technical solution: An air flow pulverizer with automatic feeding, including a pulverizing tank, a filter screen is fixedly installed inside the pulverizing tank, a discharge pipe is fixedly connected to the top of the pulverizing tank, an induced draft fan is fixedly installed on the top of the pulverizing tank, and an automatic feeding device is arranged inside the pulverizing tank;

[0007] Among them, the automatic feeding device includes a feeding pipe, the feeding pipe is fixedly connected inside the pulverizing tank, a screw conveyor for adding materials is rotatably connected inside the feeding pipe, and the right end of the screw conveyor is fixedly connected to the output end of the driving motor.

[0008] Preferably, a feed pipe is fixedly connected to the surface of the feeding pipe, and a conical hopper is fixedly connected to the top of the feed pipe.

[0014] (1) For this air flow pulverizer with automatic feeding, the screw conveyor rotates and gradually conveys the materials to the left through the grooves on the surface. The materials gradually move to the left, pass through the elbow pipe and fall on the surface of the conical disc. The materials are diffused in a circular shape through the conical disc and fall into the inside of the pulverizing tank, avoiding a large amount of materials gathering together, increasing the diffusion range of the materials inside the pulverizing tank, thereby increasing the contact area between the materials and the air flow, and finally improving the pulverizing effect of the materials.

[0015] (2) For this air flow pulverizer with automatic feeding, after the materials fall from the surface of the conical disc, the air compressor inputs high-pressure gas into the inside of the annular pipe.

A filter screen 2 is fixedly installed inside the pulverizing tank 1. A discharge pipe 3 is fixedly connected to the top of the pulverizing tank 1. An induced draft fan 4 is fixedly installed on the top of the pulverizing tank 1. A feeding pipe 5 is fixedly connected inside the pulverizing tank 1. A driving motor 6 is fixedly installed at the right end of the feeding pipe 5;

[0027] Among them, a screw conveyor 7 for adding materials is rotatably connected inside the feeding pipe 5, and the right end of the screw conveyor 7 is fixedly connected to the output end of the driving motor 6;

[0028] Among them, a feed pipe 8 is fixedly connected to the surface of the feeding pipe 5, and a conical hopper 9 is fixedly connected to the top of the feed pipe 8;

[0029] Among them, one end of the feeding pipe 5 far from the driving motor 6 is fixedly connected to an elbow pipe 10, and four connecting rods 11 are fixedly connected to the bottom of the elbow pipe 10. The lower ends of the four connecting rods 11 are fixedly connected to a conical disc 12 for dispersing materials;

[0030] When the air flow pulverizer with automatic feeding is in use, the staff first pour the materials into the conical hopper 9, and then start the driving motor 6. The materials inside the conical hopper 9 flow into the feeding pipe 5 through the feed pipe 8. The output end of the driving motor 6 rotates and drives the screw conveyor 7 to rotate. At this time, the screw conveyor 7 rotates and gradually conveys the materials to the left through the grooves on the surface. The materials gradually move to the left through the elbow pipe 10 and fall on the surface of the conical disc 12. The materials are spread out in a circular shape through the conical disc 12 and fall into the pulverizing tank 1, avoiding a large amount of materials gathering together, increasing the diffusion range of the materials inside the pulverizing tank 1, and then increasing the contact area between the materials and the air flow, and finally improving the pulverizing effect of the materials.

[0031] Among them, an air compressor 13 is fixedly installed at the bottom of the pulverizing tank 1, and an annular pipe 14 is fixedly connected to the output end of the air compressor 13;

[0032] Among them, nozzles 15 are fixedly installed on the surface of the annular pipe 14, and the nozzles 15 are evenly distributed in a circular shape on the surface of the annular pipe 14.

[0033] After the materials fall from the surface of the conical disc 12, the air compressor 13 inputs high-pressure gas into the annular pipe 14. After the high-pressure gas enters the annular pipe 14, it is sprayed outwards through multiple nozzles 15. The materials are repeatedly collided, rubbed, and sheared at the intersection of multiple high-pressure airflows and are pulverized. And by spraying high-pressure gas at different positions through multiple nozzles 15, it is more conducive to the contact between the materials and the high-pressure gas, and it is more conducive to the pulverization treatment of the materials.

[0034] Working principle: For this air classifier mill with automatic feeding, the staff pour the materials into the inside of the conical hopper 9, and then start the drive motor 6. The materials inside the conical hopper 9 flow through the feed pipe 8 into the inside of the feeding pipe 5. The drive motor 6 drives the auger 7 to rotate. The auger 7 rotates and gradually conveys the materials to the left through the grooves on its surface. The materials fall on the surface of the conical disc 12, and the materials are spread in a circular shape through the conical disc 12 and fall into the inside of the pulverizing tank 1, increasing the diffusion range of the materials inside the pulverizing tank 1. After the materials fall from the surface of the conical disc 12, the air compressor 13 inputs high-pressure gas into the inside of the annular pipe 14 and sprays it out through multiple nozzles 15. The materials are repeatedly collided, rubbed, and sheared at the intersection of multiple high-pressure airflows and pulverized. And by spraying high-pressure gas at different positions through multiple nozzles 15, it is more conducive to the contact between the materials and the high-pressure gas for pulverization treatment.
