Description

Technical Field

[0001] This utility model relates to the field of air separator technology, specifically an air separator for grain processing. Background Technology

[0002] An air separator is a device that uses wind power to separate materials. It achieves the purpose of removing or separating impurities by utilizing the difference in aerodynamic properties between materials and impurities. It is widely used in many industries such as medicinal materials, ores, and waste treatment.

[0003] The patent with publication number CN218610404U discloses an air separator for grain processing. It includes a main body, with a feed hopper connected to the upper end of the main body and a discharge hopper connected to the lower end of the main body. A first leg and a second leg are symmetrically connected to the lower end of the main body, and a fixing plate is connected between the first leg and the second leg. The device is started by a motor, which causes the fan and spiral blades to rotate. The fan performs air separation on the introduced grain, blowing impurities into the slag discharge hopper and discharging them into the collection box for easy cleaning.

[0004] However, this device directly introduces the grain that needs to be air-separated from the feed hopper and uses a fan to blow away impurities. With only one fan, it is not only difficult to ensure that impurities inside the grain are removed, but also some grain will be blown into the top of the baffle during the blowing process, thus affecting the grain air separation effect. Therefore, an air separator for grain processing is proposed to solve the problem that the existing air separator is difficult to screen grain comprehensively. Utility Model Content

[0009] Preferably, the slopes of the first guide slope and the second guide slope are both smooth, the first collection box, the second collection box, and the collection box all pass through one end of the machine body and are slidably arranged, one end of the first collection box, the second collection box, and the collection box is fixedly connected to a handle, and a filter screen is provided in the exhaust port.

[0010] Preferably, the spring is located at the bottom of the contact block and on the outer ring of the guide rod, and the top and bottom of the spring are respectively connected to the contact block and the fixing seat.

[0011] Preferably, the feeding mechanism includes a feeding seat fixedly connected to the top of the machine body. The top and bottom of the feeding seat are respectively provided with a first feeding groove and a second feeding groove. A rotating groove is provided on one side of the feeding seat. The inner cavity of the rotating groove is rotatably connected to the top of the feeding seat with a first sealing plate and a second sealing plate.

[0012] Preferably, the first sealing plate and the second sealing plate are connected by a linkage shaft that passes through the feeding seat, the first sealing plate and the second sealing plate are centrally symmetrically distributed, and the bottom diameter of the first feeding trough is smaller than the top diameter of the second feeding trough.

[0013] Preferably, a sealing frame is slidably provided on the outer ring of the feeding seat, and an adhesive strip is fixedly connected to the sealing frame and the feeding seat at the contact point. The adhesive strip is pressed against the feeding seat, and limit strips are fixedly connected to both ends of the feeding seat.

[0014] (III) Beneficial Effects

[0015] 1. This air separator for grain processing operates by simultaneously turning on a blower to blow air onto the grain as it enters through the feed inlet. Lighter impurities are blown onto the first guide slope and then collected in the area of ​​the first collection box. The initially air-separated grain falls onto the screen plate, where the screen plate rotates in conjunction with the rotating shaft and the electric push rod inside the fixed base. The vibration generated by the reset screen plate, using guide rods, springs, and contact blocks, screens the impurities into the second collection box, while the grain is discharged into the collection box. This solves the problem that existing air separators are unable to fully separate grain.

[0016] 2. In this air separator for grain processing, when adding grain, the first sealing plate is rotated into the trough to block the second feeding trough. The grain is placed into the first feeding trough, and then the second sealing plate is rotated to the top of the feeding seat. During this process, in conjunction with the linkage shaft, the first sealing plate rotates out of the trough, and the grain is discharged into the second feeding trough and enters the feed inlet. After the grain enters the machine body, the first sealing plate can be reset to block the second feeding trough and prevent dust from overflowing. At the same time, grain can continue to be added into the first feeding trough for subsequent discharge and processing, improving the convenience of feeding the air separator for grain processing.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Please refer to Figure 1-5 A grain processing air separator includes a body 1, a feed inlet 2 at the top of the body 1, a feeding mechanism 3 at the top of the body 1, a fan 4 at one end of the body 1, a fixed plate 5 fixedly connected to the inner cavity of the body 1, a first guide slope 6 fixedly connected to the top of the fixed plate 5, a screen plate 7 at the bottom of the fixed plate 5, the screen plate 7 being rotatably connected to the inner cavity of the body 1 via a rotating shaft 8, a fixed seat 9 fixedly connected to the bottom of the inner cavity of the body 1, an electric push rod 10 provided on the inner wall of the middle part of the fixed seat 9, guide rods 11 symmetrically and penetratingly provided on the top of the fixed seat 9, springs 12 symmetrically provided on the top of the fixed seat 9, contact blocks 13 fixedly connected to the top of both the electric push rod 10 and the guide rod 11, a first collection box 14 and a second collection box 15 and a collection box 16 penetratingly provided on the top of the fixed plate 5 and the bottom of the inner cavity of the body 1, respectively, a second guide slope 17 provided on the top of the inner cavity of the body 1, and an exhaust port 18 opened on the left side of the body 1.

[0025] Furthermore, the slopes of the first guide slope 6 and the second guide slope 17 are both smooth. The first collection box 14, the second collection box 15, and the collection box 16 all pass through one end of the machine body 1 and are slidably arranged. One end of the first collection box 14, the second collection box 15, and the collection box 16 is fixedly connected to a handle. A filter screen is provided inside the exhaust port 18.

[0026] Furthermore, the spring 12 is located at the bottom of the contact block 13 and at the outer ring of the guide rod 11, and the top and bottom of the spring 12 are connected to the contact block 13 and the fixing seat 9, respectively.

[0027] Furthermore, the feeding mechanism 3 includes a feeding seat 301 fixedly connected to the top of the machine body 1. The top and bottom of the feeding seat 301 are respectively provided with a first feeding groove 302 and a second feeding groove 303. A rotating groove 304 is provided on one side of the feeding seat 301. The inner cavity of the rotating groove 304 and the top of the feeding seat 301 are respectively rotatably connected with a first sealing plate 305 and a second sealing plate 306.

[0028] Furthermore, the first sealing plate 305 and the second sealing plate 306 are connected by a linkage shaft 307 that passes through the feeding seat 301. The first sealing plate 305 and the second sealing plate 306 are centrally symmetrically distributed. The bottom diameter of the first feeding trough 302 is smaller than the top diameter of the second feeding trough 303. When adding grain, the first sealing plate 305 is rotated into the rotating groove 304 to block the second feeding trough 303. The grain is placed into the first feeding trough 302. Then, the second sealing plate 306 is rotated to the top of the feeding seat 301. During the process, in coordination with the linkage shaft 307, the first sealing plate 305 rotates out of the rotating groove 304, and the grain is discharged into the second feeding trough 303 and enters the feed inlet 2. After the grain enters the machine body 1, the first sealing plate 305 can be reset to block the second feeding trough 303 to prevent dust from overflowing. At the same time, grain can continue to be added into the first feeding trough 302 for subsequent discharge and processing, improving the convenience of feeding the air separator used for grain processing.

[0029] Furthermore, a sealing frame 308 is slidably provided on the outer ring of the feeding seat 301. A rubber strip 309 is fixedly connected to the contact point between the sealing frame 308 and the feeding seat 301. The rubber strip 309 is pressed against the feeding seat 301. Limiting strips 3010 are fixedly connected to both ends of the feeding seat 301. When the first sealing plate 305 rotates out of the rotating groove 304 to discharge grain into the feed inlet 2 so that it enters the machine body 1 for processing, the sealing frame 308 is moved down to contact the limiting strip 3010, thereby sealing the rotating groove 304 to prevent dust from overflowing. Conversely, when it is necessary to rotate the first sealing plate 305 into the rotating groove 304, the sealing frame 308 is moved up, and the rubber strip 309 is used to limit the sealing frame 308, which facilitates the addition of grain.

[0030] Working Principle: When using this air separator for grain processing, the grain to be air-separated is added into the machine body 1 through the feed inlet 2. During the process, the blower 4 is turned on to blow air and screen the grain, causing lighter impurities to be blown onto the first guide slope 6 and then collected in the area of ​​the first collection box 14. The initially air-separated grain falls onto the screen plate 7. The electric push rod 10 in the rotating shaft 8 and fixed base 9 rotates the screen plate 7. The vibration generated by the return screen plate 7 using the guide rod 11, spring 12 and contact block 13 screens the impurities into the second collection box 15, while the grain is discharged into the collection box 16, thus solving the problem of... The existing air separator has the problem of not being able to screen grains completely. By cooperating with the second guide slope 17 and the first guide slope 6, the lighter impurities blown out of the grain can be smoothly guided to the area of ​​the first collection box 14. Even if some grain is blown to the first guide slope 6 along with the lighter impurities during the blowing process, the grain can stay on the first guide slope 6 under its own gravity. So when the fan 4 is stopped, the grain on the first guide slope 6 can roll onto the screen plate 7 and then fall into the collection box 16, avoiding waste or the need to re-screen the collected impurities later.
