[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example

[0025] Reference Figure 1-5 A low-voltage cable screw extruder with an exhaust gas suction structure includes a base 2 fixedly connected to the bottom of an extruder body 1 and a screw body 3 rotatably installed in the extruder body 1;

[0026] In this embodiment, an exhaust gas treatment mechanism is provided on one side of the extruder body 1, and the exhaust gas treatment mechanism includes:

[0027] The vacuum box 4 and the drive motor 5 are fixedly connected to the side wall of the base 2, and the drive motor 5 is fixedly installed on the top outer wall of the vacuum box 4. The output shaft of the drive motor 5 passes through the top of the vacuum box 4.

[0028] The top end of the transmission shaft 6 is coaxially fixedly connected to the output shaft of the drive motor 5 through a coupling. An exhaust hole 8 is opened at the bottom of the vacuum box 4. A support frame 9 is fixedly connected to the exhaust hole 8. The bottom end of the transmission shaft 6 is connected to the central inner wall of the support frame 9 through a bearing;

[0029] The suction fan blade 7 is fixedly mounted on the transmission shaft 6 and is located at the exhaust hole 8;

[0030] The activated carbon adsorption purification assembly includes a purification box 12 fixedly connected to the front of the air extraction box 4, three activated carbon filters 13 inserted into the air extraction box 4 and distributed at equal distances, and a connecting iron plate 15 fixedly connected to the top outer wall of the three activated carbon filters 13. One side of the purification box 12 is an open structure, and the other side of the purification box 12 is connected to the extruder body 1 through the suction pipe 14;

[0031] The transmission assembly includes a driving bevel gear 10 fixedly mounted on the transmission shaft 6 and a driven bevel gear 11 fixedly mounted on the screw body 3 and meshing with the driving bevel gear 10. One end of the screw body 3 passes through one side of the vacuum box 4. Through the transmission effect of the transmission assembly, a drive motor 5 can simultaneously drive the screw body 3 and the suction fan blade 7 to rotate, thereby simultaneously sucking the exhaust gas while the extruder is working, thereby effectively reducing the deployment and maintenance costs of the drive equipment, and being more economical and practical to use.

[0032] In this embodiment, four permanent magnets 16 are fixedly embedded on the top of the purification box 12. The four permanent magnets 16 are attracted to the connecting iron plate 15. A handle 17 is welded to the top outer wall of the connecting iron plate 15.

[0033] Then, by plugging the three activated carbon filters 13 on the connecting iron plate 15 into the purification box 12, the connecting iron plate 15 will be attracted by the four permanent magnets 16 after being plugged in. During subsequent disassembly, the three activated carbon filters 13 can be pulled out of the purification box 12 by simply lifting the connecting iron plate 15 upwards with the handle 17. In this way, the fixing effect of the three activated carbon filters 13 is achieved by magnetic attraction, which can facilitate the disassembly and replacement of the three activated carbon filters 13 and improve the disassembly and replacement efficiency.

[0034] The working principle of the utility model is as follows: first, the driving motor 5 controls the suction blades 7 and the driving bevel gear 10 on the transmission shaft 6 to rotate, and then the driven bevel gear 11 meshing with the driving bevel gear 10 controls the screw body 3 to rotate, thereby sucking out the exhaust gas while the extruder is working;

[0035] Secondly, the rotation of the suction fan blades 7 will generate suction, which will suck out the exhaust gas generated inside the extruder body 1 through the suction pipe 14 and enter the purification box 12. The exhaust gas will then pass through the three activated carbon filters 13 in the purification box 12 to complete the purification process. The purified gas will be discharged from the exhaust hole 8, which can effectively avoid the environmental pollution caused by the direct discharge of exhaust gas, which is beneficial to the health of workers.
