[0005] 1. The grinding barrel contains materials, abrasives and grinding fluid, which is very heavy and has high requirements for the rotating mechanism, increasing the equipment cost;

[0006] 2. The grinding barrel is tilted to one side, so the sorting screen needs to be set on one side of the grinder, which takes up extra space. Utility Model Content

[0015] In the above implementation process, the double-headed motor drives the two screws to rotate synchronously, and then drives the slide to move up and down, thereby playing the role of lifting and lowering the enclosure.

[0016] In a specific embodiment, the filtering mechanism comprises an annular filter tank, the bottom surface of the filter tank is inclined, and a discharge nozzle is arranged at the lowest end of the filter tank.

[0027] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0028] See also Figure 1-Figure 4 The present application provides an abrasive recovery mechanism, including an enclosure 10, a base 20 and a lifting mechanism 30. The enclosure 10 and the base 20 are movably fitted to form an eddy current grinding barrel. The enclosure 10 is installed on the lifting mechanism 30. An annular filtering mechanism 40 is arranged around the joint between the lower end of the enclosure 10 and the base 20. The lifting mechanism 30 is used to drive the enclosure 10 to rise, thereby forming an annular gap between the enclosure 10 and the base 20. The material stays in the grinding barrel, while the abrasive and the grinding liquid are discharged from the gap into the filtering mechanism 40 and separated again. The lifting mechanism 30 only lifts the enclosure 10, thereby effectively reducing the power requirements and the structural cost. The annular filtering mechanism 40 surrounding the grinding barrel also makes the structure more compact and reduces the space occupation.

[0029] See also Figure 1-Figure 4 The fitting surface between the enclosure 10 and the base 20 is a conical surface, and a sealing mechanism 50 is provided at the conical surface. The fitting of the conical surface helps to improve the sealing performance, and the sealing mechanism 50 is further used to improve the sealing performance.

[0030] See also Figure 1-Figure 4 The sealing mechanism 50 includes a groove 51 and a circular expansion tube 52. The expansion tube 52 is located in the groove 51. The groove 51 is opened at the bottom of the enclosure 10. The expansion tube 52 is movably pressed against the base 20. The expansion tube 52 is a rubber tube, and the inside is connected to an external air pump. When the enclosure 10 and the base 20 are conically fitted, the air pump inflates the expansion tube 52. The expansion tube 52 expands to fill the groove 51 and presses against the base 20 to form a sealing strip. When the enclosure 10 is raised, the air pump draws out the air inside the expansion tube 52, and the expansion tube 52 shrinks in the groove 51, which can prevent the abrasive from passing through the gap and causing wear to the expansion tube 52, thereby increasing the life of the expansion tube 52.

[0031] See also Figure 1-Figure 4 The lifting mechanism 30 includes a support 31, a guide rod 32 is provided on the support 31, a slide 33 is slidably connected to the guide rod 32, and the slide 33 is fixedly connected to the enclosure 10. The lifting mechanism 30 also includes a motor 34 and a screw rod 35, the screw rod 35 is rotatably connected to the support 31, the screw rod 35 is screwed to the slide 33, and the output end of the motor 34 is connected to the screw rod 35 axis. The double-headed motor 34 drives the two screw rods 35 to rotate synchronously, thereby driving the slide 33 to move up and down, thereby playing the role of lifting the enclosure 10.

[0032] See also Figure 1-Figure 4 The filter mechanism 40 includes an annular filter tank 41, the bottom surface of the filter tank 41 is inclined, and a discharge nozzle 42 is provided at the lowest end of the filter tank 41. The filter mechanism 40 also includes an annular water tank 43, the bottom surface of the water tank 43 is inclined, and a water outlet 44 is provided at the lowest end of the water tank 43. After the enclosure 10 leaves the base 20, the abrasive and the grinding liquid flow into the filter tank 41 from the gap, and the grinding liquid passes through the filter holes on the bottom wall of the filter tank 41 and enters the water tank 43 below. The abrasive is discharged from the discharge nozzle 42, and the grinding liquid is discharged from the water outlet nozzle 44.

[0033] See also Figure 1-Figure 4 The present application further provides a vortex polishing device, including the above-mentioned abrasive recovery mechanism.

[0034] The working principle of the abrasive recovery mechanism is as follows: an eddy current mechanism is provided on the base 20 to drive the internal grinding liquid, abrasive and material to form a eddy current rotation, thereby playing a grinding and polishing role. When the abrasive needs to be recovered, the external air pump first extracts the air inside the expansion tube 52, and the expansion tube 52 shrinks in the groove 51, which can avoid the abrasive from passing through the gap and causing wear to the expansion tube 52, thereby improving the life of the expansion tube 52. Then the motor 34 drives the two screws 35 to rotate synchronously, and then drives the slide 33 and the enclosure 10 to move upward a specified distance to open an annular gap. The width of this gap is between the material and the abrasive. At the same time, the eddy current mechanism runs slowly to promote the flow of internal materials, abrasives and grinding The grinding liquid flows out from the gap, and the material remains in the grinding barrel. The abrasive and grinding liquid flow into the filter tank 41 from the gap, and the grinding liquid passes through the filter holes on the bottom wall of the filter tank 41 into the water tank 43 below. The abrasive is discharged from the discharge nozzle 42, and the grinding liquid is discharged from the water outlet nozzle 44. In summary, the lifting mechanism 30 is used to drive the enclosure 10 to rise, thereby forming an annular gap between the enclosure 10 and the base 20, and the material stays in the grinding barrel, while the abrasive and grinding liquid are discharged from the gap into the filter mechanism 40 and separated again. The lifting mechanism 30 only lifts the enclosure 10, thereby effectively reducing the power requirements and the structural cost. The annular filter mechanism 40 surrounding the grinding barrel also makes the structure more compact and reduces space occupancy.
