Description

Technical Field

[0001] The utility model relates to the technical field of TPU waste film recovery, in particular to an anti-sticking material crusher. Background Art

[0002] Some waste will be generated in the process of producing TPU film. These TPU waste can be recycled and reused after reprocessing. The TPU waste film crushing and recycling equipment can refer to the Chinese utility model patent with application number CN202321376723.2, named a TPU waste film crusher. The decomposed TPU film pieces are recycled into the barrel through the fan and pipeline for subsequent processing. When the existing recycling barrel recycles the TPU film pieces, the TPU film pieces are easy to adhere to the barrel wall, resulting in incomplete recycling and increasing the cost of manual cleaning. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an anti-sticking material crusher to prevent the TPU film fragments from adhering to the barrel wall.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: an anti-sticking material crusher, including a crushing box, a recovery cylinder, a recovery trough and a fan;

[0005] The recovery cylinder is a cylindrical cylinder with a hollow interior and a feed port and a discharge port respectively provided at the upper and lower ends. The feed port is connected to the crushing box, and the discharge port is connected to the recovery trough. The inner wall of the recovery cylinder is provided with a spirally arranged air guide groove. The recovery cylinder is provided with an air inlet at the top of the air guide groove, and the air inlet is connected to the fan.

[0006] Furthermore, the fan is connected to the air inlet through an air inlet pipe, and the air inlet pipe is arranged along the tangent of the recovery cylinder.

[0007] Furthermore, the cross-sectional shape of the air guide groove is arched.

[0008] Furthermore, the groove depth of the air guide groove gradually decreases from an end close to the feed inlet to an end close to the discharge outlet.

[0009] Furthermore, a conical discharge hopper is provided at the bottom of the recovery cylinder, and the discharge port is located at the bottom of the conical discharge hopper.

[0010] The beneficial effect of the utility model is that: an anti-sticking material crusher is provided with a spiral air guide groove on the inner wall of the recovery cylinder. After the wind enters the inner cavity of the recovery cylinder from the air inlet, it moves downward along the spiral air guide groove, blowing off the TPU broken film sheets adhered to the inner wall of the recovery cylinder, thereby preventing the TPU broken film sheets from adhering to the barrel wall.

[0015] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0016] The utility model provides an anti-sticking material crusher which is applied to TPU broken film recovery equipment.

[0017] Please refer to Figure 1 to Figure 2 As shown, an anti-sticking material crusher of the utility model comprises a crushing box 1, a recovery cylinder 2, a recovery tank 3 and a fan 4;

[0018] The recovery cylinder 2 is a cylindrical cylinder with a hollow interior and a feed port 21 and a discharge port 22 at the upper and lower ends respectively. The feed port 21 is connected to the crushing box 1, and the discharge port 22 is connected to the recovery trough 3. The inner wall of the recovery cylinder 2 is provided with a spirally arranged air guide groove 23. The recovery cylinder 2 is provided with an air inlet 24 at the top of the air guide groove 23, and the air inlet 24 is connected to the fan 4.

[0019] From the above description, it can be seen that the beneficial effect of the utility model is: an anti-sticking material crusher, a spiral air guide groove 23 is arranged on the inner wall of the recovery cylinder 2, and the wind enters the inner cavity of the recovery cylinder 2 from the air inlet 24 and moves downward along the spiral air guide groove 23, blowing off the TPU broken film pieces adhering to the inner wall of the recovery cylinder 2, thereby preventing the TPU broken film pieces from adhering to the barrel wall.

[0020] In an optional embodiment, the fan 4 is connected to the air inlet 24 via an air inlet pipe 41 , and the air inlet pipe 41 is arranged along a tangent line of the recovery cylinder 2 .

[0021] From the above description, it can be known that the air inlet pipe 41 is arranged along the tangential direction, which is beneficial for the wind to move spirally downward along the air guide groove 23 after entering the inner cavity of the recovery cylinder 2.

[0022] In an optional embodiment, the cross-sectional shape of the air guide groove 23 is an arcuate shape.

[0023] From the above description, it can be seen that the cross-section design of the air guide groove 23 as an arch can reduce the adhesion of TPU film fragments to the wall of the recovery cylinder 2, and is also conducive to the wind entering the inner cavity of the recovery cylinder 2 and moving downward along the air guide groove 23 in a spiral.

[0024] Furthermore, the groove depth of the air guide groove 23 gradually decreases from an end close to the feed port 21 to an end close to the discharge port 22 .

[0025] From the above description, it can be known that such a design can reduce the adhesion of TPU film fragments to the wall of the recovery cylinder 2 and avoid the accumulation of TPU film fragments in the bottom discharge structure.

[0026] Furthermore, a conical discharge hopper 25 is provided at the bottom of the recovery cylinder 2 , and the discharge port 22 is located at the bottom of the conical discharge hopper 25 .

[0027] Please refer to Figure 1 to Figure 2 As shown, the first embodiment of the utility model is: an anti-sticking material crusher, comprising a crushing box 1, a recovery cylinder 2, a recovery tank 3 and a fan 4;

[0028] The recovery cylinder 2 is a cylindrical cylinder with a hollow interior and a feed port 21 and a discharge port 22 at the upper and lower ends respectively. The feed port 21 is connected to the crushing box 1, and the discharge port 22 is connected to the recovery trough 3. The inner wall of the recovery cylinder 2 is provided with a spirally arranged air guide groove 23. The recovery cylinder 2 is provided with an air inlet 24 at the top of the air guide groove 23, and the air inlet 24 is connected to the fan 4.

[0029] The fan 4 is connected to the air inlet 24 through an air inlet pipe 41, and the air inlet pipe 41 is arranged along the tangent of the recovery drum 2. The cross-sectional shape of the air guide groove 23 is an arcuate shape. The slot depth of the air guide groove 23 gradually decreases from the end close to the feed inlet 21 to the end close to the discharge port 22. A conical discharge hopper 25 is provided at the bottom of the recovery drum 2, and the discharge port 22 is located at the bottom of the conical discharge hopper 25.

[0030] To sum up, the anti-sticking material crusher of the utility model is provided with a spiral air guide groove on the inner wall of the recovery cylinder. After the wind enters the inner cavity of the recovery cylinder from the air inlet, it moves downward along the spiral air guide groove, blowing off the TPU broken film sheets adhering to the inner wall of the recovery cylinder, thereby preventing the TPU broken film sheets from adhering to the barrel wall.

[0031] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
