DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

The interior of the dust collection and processing box 1 is provided with a dust filter bin 13 and a dust collection bin 14 from top to bottom. A dust filter plate 15 is fixedly arranged between the dust filter bin 13 and the dust collection bin 14. An inner bracket 18 is fixedly arranged on the inner side wall of the dust filter bin 13. A double-layer filtering mechanism 8 for intercepting dust is installed on the inner bracket 18. The tops of both sides of the dust collection and processing box 1 are fixedly installed with shaking mechanisms for cleaning the surface of the double-layer filtering mechanism 8, a storage box 16 is placed at the bottom of the dust collection bin 14, and a dust suction mechanism for dust removal of the outer skin crusher of the wire and cable is fixedly installed on one side of the dust collection and processing box 1. The front of the dust filter bin 13 is hinged with an inspection bin door 10, and a timer 9 is fixedly installed on the surface of the inspection bin door 10. The front of the dust collection bin 14 is hinged with a cleaning bin door 11, and one end of the exhaust gas recovery pipe 3 is fixedly installed with a connecting flange 4;

[0021] When in use, the exhaust gas recovery pipe 3 is connected to the air inlet of the environmental protection equipment through the connecting flange 4. When working, under the negative suction of the environmental protection equipment, negative pressure will be generated at the dust suction mechanism. The dust suction mechanism is facing the wire and cable sheath crusher, and the dust generated during the crushing is sucked into the dust collection and treatment box 1, and filtered through the dust filter plate 15 and the double-layer filtering mechanism 8 to purify the dust in the exhaust gas. The filtered exhaust gas then enters the environmental protection equipment through the exhaust gas recovery pipe 3 for treatment.

[0022] See also Figure 1 and Figure 2 Further, the dust collection mechanism includes a dust collecting pipe 2 and a dust collecting hood 5 fixedly installed at one end of the dust collecting pipe 2, a pre-filter 6 is fixedly arranged at the bottom of the dust collecting hood 5, the other end of the dust collecting pipe 2 extends to the inside of the dust collecting and processing box 1, and the dust collecting pipe 2 is arranged below the dust filter plate 15;

[0023] When in use, the dust hood 5 faces the wire and cable sheath pulverizer, and the airflow containing dust will directly pass through the dust hood 5 into the dust collecting pipe 2, and finally enter the dust collection and processing box 1. The pre-filter 6 is used to intercept large-volume debris to prevent large-volume debris from entering the dust collecting pipe 2 and causing blockage.

[0024] See also Figure 1 , Figure 2 and Figure 5 , further, the shaking mechanism includes a support frame 7 and a driving motor 12 fixedly mounted on the top of the support frame 7, a cam 17 is fixedly mounted on the output end of the driving motor 12, and the driving motor 12 is electrically connected to the external power supply through the timer 9;

[0025] When in use, the timer 9 will control the driving motor 12 to work regularly, and the driving motor 12 will drive the cam 17 to rotate, thereby squeezing the double-layer filter mechanism 8 through the cam 17, causing it to shake on the inner bracket 18, thereby shaking off the dust attached to the surface of the double-layer filter mechanism 8, preventing the filter mesh from being blocked, and improving the smoothness of airflow filtration.

[0026] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 , further, the double-layer filtering mechanism 8 includes two frames 81 and a connecting rod 82 fixedly arranged between the two frames 81, the four corners at the bottom ends of the two frames 81 are installed with elastic sliding column assemblies, the four corners at the top ends of the two frames 81 are rotatably provided with locking components 83, a first steel wire filter 84 is installed in the middle of the top end of one frame 81, and a second steel wire filter 85 is fixedly installed in the middle of the top end of the other frame 81, the cam 17 is arranged opposite to the edge of the frame 81, the elastic sliding column assembly includes a plug-in column 86 and a threaded cap 88 sleeved on the bottom end of the plug-in column 86, a spring 87 is sleeved on the surface of the plug-in column 86, and the plug-in column 86 is slidably arranged on the inner bracket 18;

[0027] When in use, the airflow passes through the second steel wire filter 85 and the first steel wire filter 84 from bottom to top in turn. After two filtrations, the second steel wire filter 85 and the first steel wire filter 84 are both 100-mesh filters, which can intercept 10-100um dust particles. When the dust collection and treatment box 1 is not in use, the staff can regularly open the maintenance compartment door 10, and turn the locking parts 83 in turn to disengage them from the filter. Then the filter can be removed from the frame 81 for cleaning or replacement, which is convenient for maintenance.

[0028] When the embodiment of the present application is in use: the exhaust gas recovery pipe 3 is connected to the air inlet of the environmental protection equipment through the connecting flange 4, and the suction force of the environmental protection equipment is used. The airflow containing dust will directly pass through the dust collecting hood 5 and immerse into the dust collecting pipe 2, and finally enter the dust collection and treatment box 1. The dust is first filtered by the dust filter plate 15. At this time, the large volume of particulate matter will sink into the storage box 16 under the action of gravity. The airflow of the preliminary filtration will rise, pass through the second wire filter 85 and the first wire filter 84 in turn, and the filtered gas will be recovered by the exhaust gas. The tube 3 enters the environmental protection equipment and is purified by the environmental protection equipment. During the filtration period, the timer 9 controls the driving motor 12 to work regularly. The driving motor 12 drives the cam 17 to rotate, thereby squeezing the frame 81 through the cam 17. Under the transmission of the connecting rod 82, the two frames 81 squeeze the spring 87 on the inner bracket 18 to contract. When the raised part of the cam 17 is separated from the frame 81, under the elastic force of the spring 87, the frame 81 drives the wire filter to reset and shake, thereby shaking off the dust attached to the surface to ensure the smoothness of gas circulation.
