[0002] There are various types of abrasives such as emery, green silicon carbide, black silicon carbide, polishing powder, etc. During the production process of emery abrasives, it is necessary to sort the abrasives according to specification requirements and screen out unqualified abrasives. Therefore, a sorting machine is required.

[0003] A Chinese patent with the publication number CN219702612U discloses an abrasive sorting machine, specifically related to the technical field of abrasive sorting machines. It includes a machine body for abrasive diversion, and a diversion component for abrasive diversion is arranged inside the machine body; a driving component for driving the diversion component is arranged at the bottom end of the machine body; a plurality of buffer components for buffering the vibration received by the machine body are arranged at the bottom end of the machine body; a protection component for anti-corrosion and anti-collision is arranged outside the buffer component. In the utility model, through the inner cylinder and the outer cylinder being sleeved inside and outside, the moving spring can be fully protected to avoid the spring being distorted and damaged by external collisions, and at the same time, it can also prevent external substances such as moisture from contacting the spring and causing the spring to be corroded. Moreover, with the help of the setting of the sealing ring, the sealing performance of the inner cylinder moving inside the outer cylinder can be enhanced, thereby avoiding external impurities from entering the inner cylinder through the gap between the inner cylinder and the outer cylinder and contacting the spring. Thus, the service life and use effect of the spring can be guaranteed.

[0004] During the screening process of existing sorting machines for abrasives, generally, only one screening of the abrasives can be carried out. A small amount of unqualified abrasives are easily mixed inside the qualified abrasives, resulting in poor purity of the abrasives. Therefore, an abrasive sorting machine is proposed to solve the above problems. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0019] Please refer to Figures 1-4 As shown, an abrasive separator includes a support frame 1. A separation box 2 is installed on the support frame 1. A first discharge hopper 3 is installed on one side wall of the separation box 2. A discharge pipe 4 is installed on the first discharge hopper 3. A cavity 5 is formed inside the discharge pipe 4. A screening mesh 6 is installed on the inner wall of the discharge pipe 4. A guide pipe 7 is installed on the side wall of the discharge pipe 4. Another side of the guide pipe 7 is installed with an aggregate box 8. The aggregate box 8 is fixedly installed on the support frame 1. A placement groove is formed inside the aggregate box 8. An aggregate box 9 is placed in the placement groove. A handle 10 is installed on the outer wall of the aggregate box 9. The right side wall of the aggregate box 9 is a filter plate. An exhaust box 11 is installed on the side wall of the aggregate box 8. Exhaust grooves 12 are formed on the two side walls of the exhaust box 11 and the right side wall of the aggregate box 8. A first motor 13 is installed on the inner wall of the exhaust box 11 through a machine base. A rotor 14 is installed on the output shaft of the first motor 13. A fan blade 15 is installed on the rotor 14. A sieve plate 16 and a guide plate 17 are installed on the inner wall of the separation box 2. A second discharge hopper 18 is installed on the other side wall of the separation box 2. A feed hopper 19 is installed on the top plate of the separation box 2; during operation, in the process of screening abrasives by the existing separator, generally only one-time screening of abrasives can be performed, and a small amount of unqualified abrasives are likely to be mixed in the qualified abrasives, resulting in poor purity of the abrasives. Pour the abrasives into the separation box 2 from the feed hopper 19. The abrasives fall onto the sieve plate 16. By operating two vibration motors 29, the vibration block 30 is driven to vibrate. The vibration block 30 drives the separation box 2 to vibrate. By setting the spring 28, the separation box 2 vibrates at a high frequency on the support frame 1. The separation box 2 drives the sieve plate 16 to vibrate at a high frequency, causing the abrasives to jump on the sieve plate 16. Small-particle abrasives fall through the sieve holes onto the guide plate 17. Then, the large-particle abrasives move from the sieve plate 16 to the first discharge hopper 3 and are discharged. The small-particle abrasives move from the guide plate 17 to the first discharge hopper 3 and are discharged;

[0020] After the abrasive is discharged from the first discharge hopper 3, the abrasive falls into the discharge pipe 4. By operating the first motor 13, the rotor 14 is driven to rotate at a high speed. The rotor 14 drives the fan blade 15 to rotate at a high speed, causing an instant vacuum in the exhaust box 11, the aggregate box 8, the material guide pipe 7, and the discharge pipe 4, creating a pressure difference with the outside world. Under the action of the pressure difference, the outside air is sucked into the cavity 5 of the discharge pipe 4. During the process of the abrasive passing through the discharge pipe 4, the small-particle abrasives in the abrasive are lighter in weight and are sucked into the cavity 5 along with the air, while the qualified large-particle abrasives are blocked by the screening mesh 6 and discharged from the discharge pipe 4 under the action of gravity. The small-particle abrasives enter the material guide pipe 7 from the cavity 5 and then enter the aggregate box 9 of the aggregate box 8. The filter plate on the right side of the aggregate box 9 filters the small-particle abrasives and air. The small-particle abrasives are collected by the aggregate box 9, and the filtered pure air is discharged from the exhaust groove 12, realizing the secondary screening of the abrasive, avoiding the mixing of a small amount of unqualified abrasives in the qualified abrasives, and being beneficial to improving the sorting purity of the abrasive.

[0021] Please refer to Figure 5 As shown, a glass window 20 is installed on the side wall of the sorting box 2. Two fixing blocks 21 are symmetrically installed on the side wall of the sorting box 2. A guide rod 22 is installed on one of the fixing blocks 21, and a lead screw 23 is rotatably installed on the other fixing block 21. A knob 24 is installed on the top side of the lead screw 23. A lifting plate 25 is sleeved on the lead screw 23 and the guide rod 22. A pushing plate 26 is installed on the bottom side of the lifting plate 25. A plate groove is opened on the top plate of the sorting box 2, and the pushing plate 26 passes through the plate groove. Four groups of connecting frames 27 are installed on the sorting box 2. A spring 28 is installed on the bottom side of the connecting frame 27, and the spring 28 is fixedly connected to the support frame 1. Two vibration motors 29 are symmetrically installed on the support frame 1 through the machine base. A vibration block 30 is installed on the output shaft of the vibration motor 29, and the vibration block 30 is fixedly connected to the bottom side of the sorting box 2. During operation, in the process of screening the abrasive by the existing sorting machine, the abrasive is prone to accumulate, which easily causes incomplete screening of the abrasive and poor sorting effect. By rotating the knob 24, the lead screw 23 is driven to rotate. The lead screw 23 drives the lifting plate 25 thereon to move vertically. The lifting plate 25 drives the pushing plate 26 to move vertically, realizing the adjustment of the distance between the pushing plate 26 and the sieve plate 16. By pouring the abrasive into the sorting box 2 from the feed hopper 19, the abrasive falls onto the sieve plate 16. The sieve plate 16 vibrates at a high frequency, driving the abrasive to vibrate at a high frequency, and the abrasive will move downward along the slope of the sieve plate 16. During the process of passing through the pushing plate 26, the pushing plate 26 blocks the accumulated abrasive, causing the abrasive between the pushing plate 26 and the sieve plate 16 to move downward. After the abrasive passes through the pushing plate 26, it is evenly spread on the sieve plate 16, and the spreading thickness is the adjusted distance. At this time, the spreading thickness of the abrasive is relatively thin, avoiding the difficulty of the abrasive jumping on the sieve plate 16 caused by the accumulation of the abrasive, realizing the effective vibration screening of the abrasive, and being beneficial to improving the sorting effect.

[0022] Working principle: During the screening process of abrasives by existing separators, generally only one-time screening of abrasives can be carried out. A small amount of unqualified abrasives are likely to be mixed inside the qualified abrasives, resulting in poor purity of the abrasives. By pouring the abrasives from the feed hopper 19 into the sorting box 2, the abrasives fall onto the sieve plate 16. Through the operation of two vibration motors 29, the vibration block 30 is driven to vibrate. The vibration block 30 drives the sorting box 2 to vibrate. By setting the spring 28, the sorting box 2 vibrates at a high frequency on the support frame 1. The sorting box 2 drives the sieve plate 16 to vibrate at a high frequency, causing the abrasives to jump on the sieve plate 16. Small-particle abrasives fall through the sieve holes onto the guide plate 17, and then the large-particle abrasives move from the sieve plate 16 to the first discharge hopper 3 and are discharged. The small-particle abrasives move from the guide plate 17 to the first discharge hopper 3 and are discharged. After the abrasives are discharged from the first discharge hopper 3, they fall into the discharge pipe 4. Through the operation of the first motor 13, the rotor 14 is driven to rotate at a high speed. The rotor 14 drives the fan blade 15 to rotate at a high speed, making the exhaust box 11, the aggregate box 8, the guide pipe 7, and the discharge pipe 4 instantly in a vacuum state, creating an air pressure difference with the outside world. Under the action of the pressure difference, the outside air is sucked into the cavity 5 of the discharge pipe 4. During the process of the abrasives passing through the discharge pipe 4, the small-particle abrasives inside the abrasives are lighter in weight and are sucked into the cavity 5 along with the air, while the qualified large-particle abrasives are blocked by the sieve mesh 6 and are discharged from the discharge pipe 4 under the action of gravity. The small-particle abrasives enter the guide pipe 7 from the cavity 5 and then enter the aggregate box 9 of the aggregate box 8. The filter plate on the right side of the aggregate box 9 filters the small-particle abrasives and air. The small-particle abrasives are collected by the aggregate box 9, and the filtered pure air is discharged from the exhaust groove 12, realizing the secondary screening of the abrasives, avoiding the mixing of a small amount of unqualified abrasives in the qualified abrasives, and being beneficial to improving the sorting purity of the abrasives. During the screening process of abrasives by existing separators, the abrasives are prone to accumulation, which easily causes incomplete screening of the abrasives and poor sorting effect. By rotating the knob 24, the lead screw 23 is driven to rotate. The lead screw 23 drives the lifting plate 25 thereon to move vertically. The lifting plate 25 drives the pushing plate 26 to move vertically, realizing the adjustment of the distance between the pushing plate 26 and the sieve plate 16. By pouring the abrasives from the feed hopper 19 into the sorting box 2, the abrasives fall onto the sieve plate 16. The sieve plate 16 vibrates at a high frequency, driving the abrasives to vibrate at a high frequency, and the abrasives will move downward along the slope of the sieve plate 16. During the process of passing through the pushing plate 26, the pushing plate 26 blocks the accumulated abrasives, causing the abrasives between the pushing plate 26 and the sieve plate 16 to move downward. After the abrasives pass through the pushing plate 26, they are evenly spread on the sieve plate 16, and the spreading thickness is the adjusted distance. At this time, the spreading thickness of the abrasives is relatively thin, avoiding the difficulty of the abrasives jumping on the sieve plate 16 caused by the accumulation of abrasives, realizing the effective vibration screening of the abrasives, and being beneficial to improving the sorting effect.
