However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0023] Example 1
[0024] See also Figure 1-Figure 5 The utility model provides a technical solution: a grinding device for recycling unqualified PVC boards, comprising: a grinding box 1, a group of wear-resistant lining plates 2 are fixedly installed on the inner surface wall of the grinding box 1, a motor 3 is fixedly installed on one side of the outer wall of the grinding box 1, a turntable 4 is fixedly installed on the output end of the motor 3, a fixed column 5 is fixedly inserted on one side of the outer wall of the turntable 4, a group of sliders 6 are movably embedded on the inner surface wall of the turntable 4, an abrasive knife 7 is fixedly installed on the bottom of each slider 6, a metal rod 8 is fixedly inserted on one side of the outer wall of each slider 6, a disc 9 is movably sleeved on the outer wall of the fixed column 5, a group of slide grooves 10 are opened on one side of the outer wall of the disc 9, and each metal rod 8 is movably inserted on the inner surface wall of each slide groove 10, and a fixing nut 11 is movably sleeved on the outer wall of the fixed column 5.
[0025] The effect achieved by the entire embodiment 1 is that when the motor 3 is started, the turntable 4 is driven to rotate. When the turntable 4 rotates, the abrasive knife 7 is driven to rotate. At this time, the PVC material is poured into the grinding box 1. Under the friction between the high-speed rotation of the abrasive knife 7 and the wear-resistant lining 2, the PVC material is ground into powder. When the size of the PVC material particles needs to be changed, the fixing nut 11 is first loosened, and then the disc 9 is rotated. When the disc 9 rotates, the metal rod 8 slides along the slide groove 10, and then the slider 6 can be driven to move outward, so that the distance between the abrasive knife 7 and the wear-resistant lining 2 can be changed, and then the size of the PVC material particles can be changed.
[0026] Example 2
[0027] like Figure 1-Figure 5 As shown, the outer wall of the fixed column 5 is movably sleeved with a baffle 12, and the baffle 12 is arranged on one side of the outer wall of the disc 9, both sides of the outer wall of the grinding box 1 are movably embedded with movable frames 13, and both sides of the inner walls of the two movable frames 13 are fixedly installed with filter screens 14, a cooling chamber 15 is opened inside the grinding box 1, a liquid injection end 16 is arranged on the top of the grinding box 1, and a liquid discharge end 17 is arranged at the bottom of the grinding box 1, a box door 18 is arranged on one side of the outer wall of the grinding box 1, and a feeding end 19 is arranged on one side of the outer wall of the box door 18, one side of the outer wall of the grinding box 1 is fixedly connected with an exhaust pipe 20, the output end of the exhaust pipe 20 is fixedly connected with a wind tube 21, and a fan 22 is fixedly installed on the inner wall of the wind tube 21, and two legs 23 are fixedly installed at the bottom of the grinding box 1, and bottom plates 24 are fixedly installed at the bottoms of the two legs 23.
[0028] The effect achieved by the entire embodiment 2 is that the baffle 12 can prevent the powder from entering the interior of the turntable 4 and affecting the movement of the slider 6. By pulling the movable frame 13, the filter 14 can be pulled out of the grinding box 1, thereby facilitating the replacement of the filter 14. A refrigerant such as liquid nitrogen can be added to the cooling chamber 15 through the injection end 16, so that the wear-resistant box 1 can be heat-dissipated. The refrigerant in the cooling chamber 15 can be discharged through the discharge end 17. By starting the fan 22, the PVC powder that meets the requirements can be extracted, thereby achieving the collection effect.
[0029] The use method and working principle of the device are as follows: when using, first loosen the fixing nut 11, and then rotate the disc 9. When the disc 9 rotates, the metal rod 8 will slide along the slide groove 10, and then drive the slider 6 to move outward, so as to change the distance between the abrasive knife 7 and the wear-resistant lining plate 2, and then change the size of the PVC material particles. Then pull the movable frame 13 to pull the filter screen 14 out of the grinding box 1, replace the filter screen 14, and make the holes of the filter screen 14 meet the requirements. After the setting is completed, close the box door 18, and add the PVC material into the grinding box 1 through the feeding end 19, and then start the motor 3, which will drive the turntable 4 to rotate. When the turntable 4 rotates, it will drive the abrasive knife 7 to rotate. Under the friction between the high-speed rotation of the abrasive knife 7 and the wear-resistant lining plate 2, the PVC material will be ground into powder. Then start the fan 22, and the PVC powder that meets the requirements can be extracted from the filter screen 14, and then enter the container at the bottom through the air duct 21. In summary, the problems raised in the above background are solved.
