Description

Technical Field

[0001] This utility model relates to the field of grain air separation, and in particular to an air separation cleaning device. Background Technology

[0002] Air separation cleaning equipment is a device that uses airflow principles to separate and clean materials. It separates impurities of different densities, shapes, or sizes from raw materials by adjusting the airflow speed and direction. This equipment is commonly used in industries such as grain processing and recycled material handling, where it can efficiently remove impurities, improving product quality and production efficiency.

[0003] While existing technologies can achieve certain grain screening effects, they have drawbacks: existing air-separation cleaning equipment lacks efficient separation of batch rice husks, iron filings, and minerals in a flow-limiting manner. This results in a large quantity and high speed of feeding, leading to discharge before screening can be completed, thus affecting the screening effect of the device. In view of this, we propose an air-separation cleaning device that solves the above problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing an air separation cleaning device.

[0005] The technical solution of this utility model is as follows: an air separation cleaning device, including a box, a feed inlet, a baffle, a guide channel and a guide plate. The feed inlet is embedded in one side of the upper end of the box. The baffle is fixed at the lower end of the feed inlet. An inclined nozzle is fixed below the baffle on the inner wall of the box. A guide channel is provided below the nozzle. An electromagnetic plate is fixed on the outer wall of one side of the inner wall of the guide channel. A guide plate is provided at the lower end of the guide channel.

[0006] When using this device, the material is poured in through the feed inlet. The rotating motor drives the cam to rotate continuously. The cam drives the moving screen with an elastic mechanism to move relative to the fixed screen, causing the material to fall alternately through the gap between the two. This achieves a certain flow restriction effect. After the material falls, it passes the lower end of the baffle. The lighter rice husks are blown by the nozzle to the top of the baffle and then fall into the box, exiting from the discharge port. The remaining material, including minerals and iron, passes through the guide channel. At this time, the electromagnetic generator is turned on, and the servo motor drives the baffle to rotate counterclockwise to its limit position. Iron filings are adsorbed on one side of the guide channel, while other materials are discharged from the lower end of the guide channel through the guide plate and exit from the discharge port. After the batch processing of materials is completed, the servo motor drives the guide plate to rotate clockwise to its limit, and then the electromagnetic generator is turned off. The iron filings are discharged from the discharge port along the guide plate. This device has efficient batch processing of rice husks, minerals, and iron filings by air separation and has high practicality.

[0007] Preferably, the upper opening of the feed inlet is designed to be expanded, a fixed screen is fixed inside the feed inlet, an installation groove is provided on one side of the upper end of the fixed screen, a movable screen is movably installed inside the installation groove, a spring is fixed between one end of the movable screen and the inner wall of the installation groove, and the screen openings are distributed in a linear array on the surfaces of the fixed screen and the movable screen.

[0008] Preferably, a mounting frame is fixed to one side of the outer wall of the feed inlet, and a cam is rotatably mounted between the mounting frames. The surface of the cam is in contact with the outer wall of the moving screen. A rotating motor is fixed to the upper end of the mounting frame, and the output shaft of the rotating motor is fixedly connected to the rotation center of the upper end of the cam.

[0009] Preferably, a blower is fixed to one outer wall of the box body, the blower is connected to the nozzle, a base is fixed to the lower end of the box body, the lower end of the box body is designed with a slope, and a discharge port one, a discharge port two and a discharge port three are arranged in sequence below the box body, a collection trough is fixed to the lower end of one side of the box body, and a glass plate is fixed to one outer wall of one side of the box body.

[0010] Preferably, a third baffle is provided on one side of the first baffle, the lower end of the third baffle is fixedly connected to the lower end of the box body, and a second baffle is provided at the lower end of the first baffle, the lower end of the second baffle is fixedly connected to one side of the upper end of the guide channel, and the other side is fixedly connected to one side of the third baffle.

[0011] Preferably, an electromagnetic generator is provided on one side of the guide channel, and the electromagnetic generator is fixed to the outer wall of one side of the baffle.

[0012] Preferably, a baffle four is fixed at the lower end of the guide channel, a guide plate is rotatably installed at the lower outlet of the guide channel, a servo motor is fixed on one side of the outer wall of the guide channel, and the output shaft of the servo motor is fixedly connected to the rotation center of one side of the guide plate.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] I. When using this utility model, a blower and nozzle can be used to blow rice husks away from the material. Then, other materials enter the guide channel and, with the participation of an electromagnetic generator, iron filings and other minerals are separated.

An inclined nozzle 12 is fixed below the baffle 13 on the inner wall of the housing 1. The guide channel 10 is provided below the nozzle 12. An electromagnetic plate 9 is fixed on the outer wall of one side of the inner wall of the guide channel 10. The guide plate 27 is provided at the lower end of the guide channel 10.

[0030] When using this device, material is poured in through the feed inlet 7. The rotating motor 23 drives the cam 24 to rotate continuously. The cam 24 drives the moving screen 22 with an elastic mechanism to move relative to the fixed screen 21, causing the material to fall alternately through the gap between the two. This achieves a certain flow restriction effect. After falling, the material passes the lower end of the baffle 13. The lighter rice husks are blown by the nozzle 12 to the top of the baffle 8 and then fall into the box 1, exiting from the discharge outlet 18. The remaining material, including minerals and iron, passes through the guide channel 10. At this time, the electromagnetic generator 15 is turned on, and the servo motor 26 drives the baffle to rotate counterclockwise to the limit position. The iron filings will be attracted to one side of the guide channel 10, and other materials will be discharged from the lower end of the guide channel 10 through the guide plate 27 and out of the discharge port 16. After the batch processing of materials is completed, the servo motor 26 drives the guide plate 27 to rotate clockwise to the limit, and then the electromagnetic generator 15 is turned off. The iron filings are discharged from the discharge port 17 along the guide plate 27. This device has efficient batch air separation processing of rice husks, minerals and iron filings, and has high practicality.
