[0026] Specifically, in use, the setting of the driving element can drive the spiral blade 6, the spiral plate tooth 7 and the throwing air blade 8 to rotate, the spiral blade 6 pushes the residual film mixture to the spiral plate tooth 7, and the residual film mixture is impacted and scattered by the spiral plate tooth 7, at the same time, the rotating throwing air blade 8 generates negative pressure in the separation bin 2, the residual film with light weight moves to the film outlet pipe 4 and is discharged, while the heavier cotton stalk, soil particles and other impurities fall on the separation concave screen 9 and are discharged, thereby realizing rapid impurity removal and separation of the residual film mixture, greatly improving the recycling rate of the residual film, and reducing environmental pollution and resource waste.
[0027] The driving element includes a motor 51 fixedly installed on the rack 1, and the shaft of one end of the drum 5 and the output end of the motor 51 are fixedly connected with a belt-connected pulley 52.
[0028] Specifically, in use, the output end of the motor 51 drives the pulley 52 and the drum 5 to rotate continuously by starting the motor 51, which can drive the spiral blade 6, the spiral plate tooth 7 and the throwing air blade 8 to rotate together, and realize rapid impurity removal and separation of the residual film mixture.
[0029] The material pipe includes an inlet pipe 3 and an outlet pipe 4 communicated at the top of the separation bin 2, the inlet pipe 3 is located directly above the spiral blade 6, and the outlet pipe 4 is located directly above the throwing air blade 8.
[0030] Specifically, the setting of the inlet pipe 3 and the outlet pipe 4 can facilitate the feeding and discharging of the residual film mixture.
[0031] The outlet of the outlet pipe 4 is fixedly connected with a mounting frame 41, and the surface of the mounting frame 41 is provided with a mounting hole 42.
[0032] Specifically, by the installation of the frame 41 and the installation hole 42, the external conveying pipe can be conveniently connected, so that the separated residual film can be conveniently conveyed to the designated position.
[0033] In the present residual film mixture impurity removal device, in order to improve the smoothness of the axial conveying of the film impurities, the feeding section La adopts a spiral structure, and during operation, the spiral blade 6 moves the film impurities in the form of intermittent spiral to the separation section Lb, and then blows out through the discharge section Lc.
[0034] In the present residual film mixture impurity removal device, during the separation of the residual film and the impurities such as cotton stalks, it is required that the spiral plate tooth 7 has strong impact and scattering functions, and also has strong axial air conveying performance. Therefore, the spiral plate tooth 7 is made of spiral blade shearing with a thickness Mh=10mm and a pitch of 500mm, a central angle θt of 40°, and the end surface of the spiral plate tooth 7 is treated with a circular arc to avoid winding of the residual film.
[0035] In addition, the tooth root circle diameter Dto of the spiral plate tooth 7 is equal to the diameter Dz of the separation bin 2. If the diameter Dz of the separation bin 2 is too small, the residual film is easy to wind, and at the same time, the effective area of the separation concave screen 9 is reduced. However, if the diameter Dz of the separation bin 2 is too large, the operation power consumption will increase. Therefore, the circumference of the diameter Dz of the separation bin 2 should be greater than 1.5 times the length of the residual film.
[0036] The tooth top circle diameter Dth of the spiral plate tooth 7 is equal to the sum of the diameter Dz of the separation bin 2 and twice the height Ht of the spiral plate tooth 7, and is less than the radius of the separation concave screen 9, i.e.
[0037]
[0038] Dz——diameter of separation bin 2
[0039] Lp——average residual film length
[0040] Ht——height of spiral plate tooth 7

According to the maximum length of 308.5mm, it can be obtained that the tooth root circle diameter Dto of the spiral plate tooth 7 should be greater than or equal to 294.6mm, and the tooth top circle diameter Dth is 600mm. The arrangement of the spiral plate tooth 7 has an important influence on the operation stability, power consumption and film impurity separation efficiency. In order to eliminate the circumferential force generated during operation, the spiral plate tooth 7 adopts a double-head spiral line arrangement, and the arrangement mode is as shown in Figure 7
[0042] In the device, in order to meet the demand of resource utilization of the broken cotton stalks, the length of the broken cotton stalks should be less than 50mm, in order to ensure the smooth penetration of the broken cotton stalks through the screen hole, the length hk of the screen hole is 70mm, the width dk of the screen hole is 15mm, in order to improve the screening efficiency, the lateral hole distance ck is 30mm, and the longitudinal hole distance kk is 100mm, and the opening rate of the separation concave screen 9 is 33.39% through calculation.
[0043] Working principle: in the use process of the device, the motor 51 is started, then the residual film mixture is put into the separation bin 2 through the film inlet pipe 3, the output end of the motor 51 drives the belt pulley 52 and the roller 5 to rotate continuously, and drives the spiral blade 6, the spiral plate tooth 7 and the throwing fan blade 8 to rotate together, the spiral blade 6 pushes the residual film mixture to the spiral plate tooth 7, and impacts and scatters the residual film mixture through the spiral plate tooth 7, and cooperates with the rotating throwing fan blade 8, so that the negative pressure is generated in the separation bin 2, under the action of the negative pressure, the residual film with light weight moves to the film outlet pipe 4 and is discharged, and the heavy cotton stalks, soil particles and other impurities fall on the separation concave screen 9 and are discharged, so that the rapid impurity separation of the residual film mixture is realized, the recycling rate of the residual film is greatly improved, and thus the environmental pollution and resource waste are reduced.
