[0003] In order to better implement the policy of energy conservation, emission reduction and green development, the treatment method for waste cables is to reprocess cable particles, so as to achieve the effect of recycling. At present, the treatment method for waste cable particles is to directly screen them. However, impurities and dust will adhere to the waste cables themselves. The method of directly filtering and using them cannot guarantee the quality of the cable particles. Moreover, during the screening process of cable particles at present, the sieve holes are prone to blockage, and workers need to dredge them, which greatly increases the workload of the workers.

[0014] Preferably, a filter screen is provided on the inner wall of the fixed cylinder, and the filter screen is communicated with the fourth slot.

[0015] Compared with the prior art, the beneficial effects of the present invention are: In the present invention, by providing a fixed cylinder, a fixed ring and a movable plate, when the cable particles need to be processed, the cable particles are filled into the inner part of the feeding ring. Subsequently, by stirring them with the movable plate, the impurities on the cable particles can be preliminarily shed. Then, the cable particles are classified and screened through the sieve holes. When the falling cable particles pass through the filter screen on the inner wall of the fixed cylinder, the fixed cylinder will further remove the remaining impurities on the cable particles. Subsequently, the automatic cleaning of the dust attached to the cable particles is completed; Inject a preset amount of cable material particles into the inner part of the feeding ring through the feeding pipeline. Subsequently, drive the movable plate to move downward to the preset use position by the electric lifting rod. At this time, start the rotating motor to drive the movable plate to rotate. By rotating the movable plate, the cable material particles in the feeding ring can rub against each other, so that the impurities attached to the cable material particles fall off; In the process of unloading the cable particles, by adjusting the position of the movable plate in the loading ring and then stirring the cable particles in the loading ring through the movable plate, the unloading smoothness of the cable particles in the loading ring can be increased. At the same time, through this stirring method, the small-sized cable particles and the large-sized cable particles in the loading ring can be stirred and separated, so that the device can separate the large-sized cable particles from the small-sized cable particles more thoroughly. After the separation of the cable particles is completed, the top of the plug-in rod rises to a position at the same horizontal use height as the top of the movable bottom plate, and the top of the lifting plate rises to a position at the same horizontal use height as the top of the feeding ring. Then the movable plate rotates to a use state perpendicular to the fixed rod, and the electric lifting rod extends downward so that the bottom of the movable plate abuts against the top of the movable bottom plate. Then, the sliding electric slider slides in the sliding groove so that the movable plate can scrape the cable particles on the movable bottom plate and scrape the cable particles on the movable bottom plate into the inside of the fixed ring, completing the automatic unloading of the cable particles on the movable bottom plate. After the device has been used for a period of time, when the sieve holes are blocked, the sieve holes can be automatically cleared by moving the plug-in rod in the sieve holes, thereby increasing the functional stability and convenience of the device.

[0016] The present invention is provided with a plug-in rod and a lifting plate. After the plug-in rod rises to a preset use height position, the fan installed at the bottom of the lifting plate is started, and the air outlet jets outward. In combination with the movable plate, the cable material particles are stirred. Not only can the stirring rate of the cable material particles by the device be accelerated by the rising airflow blowing the cable material particles to turn them over, but also the dust falling off when the cable material particles are stirred can be blown upwards and then sucked away through the dust suction pipe preset above the device. Not only can smoke and dust be prevented from spreading on the site, but also the floating dust generated during the stirring of the cable material particles can be removed in advance, which is convenient for the stability of the subsequent functions of the device. After the stirring of the cable material particles is completed, the sieve holes are opened, and the cable material particles fall from the sieve holes to the top of the lifting plate, and at the same time, the rotating motor is started, and the rotating motor drives the lifting plate to rotate. Through the rotation of the lifting plate, the cable particles that fall on the lifting plate can be swung around, and the cable particles hit the inner wall of the fixed cylinder, so that the impurities remaining on the cable particles can be shaken off on the inner wall of the fixed cylinder by impact, and then the cable particles roll downward on the inner wall of the fixed cylinder, and at this time, the dust suction fan connected to the third slot is started, and during the rolling process of the cable particles, the residual dust on the cable particles will pass through the filter on the inner wall of the fixed cylinder into the interior of the fourth slot and then be adsorbed and removed.

And the lifting plate 15 is provided with an opening corresponding to the air inlet hole 25. The air outlet holes 24 jet air outwards. Combining with the way of stirring the cable material particles by the movable plate 4, not only can the stirring rate of the device for the cable material particles be accelerated by the rising air flow to blow the cable material particles to turn over, but also the dust shed during the stirring of the cable material particles can be blown upwards, and then be sucked away through the preset dust suction pipe above the device. This can not only prevent the site from being filled with smoke and dust, but also remove the floating dust generated during the stirring process of the cable material particles in advance, which is convenient for the use stability of the subsequent functions of the device.

[0029] As a technical optimization solution of the present invention, a filter screen is provided on the inner wall of the fixed cylinder 1, and the filter screen is communicated with the fourth slot 19.

[0030] When the present invention is in use, the device is used for the case where there are many dust impurities attached to the cable material particles. The electrical equipment used in the device is powered by connecting to an external power supply through wires. In the device, the electrical equipment in the device is controlled by setting a control system. A blower is provided at the bottom of the lifting plate 15, and the air outlet of the blower is connected to a plurality of conduit branch pipes through a main conduit. The end of the conduit branch pipe far from the blower passes through the opening at the bottom of the lifting plate 15 and is connected to the air inlet hole 25. The aperture of the filter screen provided on the inner wall of the fixed cylinder 1 is smaller than the aperture of the cable material particles falling thereon. A suction feeding device is connected at the first slot 5. The suction feeding device is a mature existing technology, so no more elaboration will be made on it. A feeding conveyor device is provided below the second slot 8. The feeding conveyor device can be a conveyor belt or a conveying pipe. A dust suction pipe is preset above the top of the feeding ring 26. The dust suction pipe is a mature existing technology, so no more elaboration will be made on it. The bottom of the third slot 9 is connected to a dust suction blower preset outside the device through a pipe. The distribution of the plugging rods 16 allows the cable material particles to flow above the lifting plate 15.

[0031] When the device needs to process the cable material particles, a feeding pipe is provided above the top of the feeding ring 26. The feeding pipe is a mature existing technology, so no more elaboration will be made on it. A preset amount of cable material particles is injected into the interior of the feeding ring 26 through the feeding pipe. Subsequently, the electric lifting rod 6 drives the movable plate 4 to move downward to the preset use position. At this time, the rotary motor 7 is started, thereby driving the movable plate 4 to rotate. By rotating the movable plate 4, the cable material particles in the feeding ring 26 can be rubbed against each other, so that the impurities attached to the cable material particles fall off. When agitating the cable material particles, the electric telescopic rod 21 makes a contraction movement, combined with the upward movement of the electric extension rod 18, so as to drive the plugging rod 16 to move upward inside the sieve hole 14. After the plugging rod 16 rises to the preset use height position, the blower installed at the bottom of the lifting plate 15 is started, and the air outlet hole 24 jets air outwards. Combined with the way of agitating the cable material particles by the movable plate 4, not only can the rate of agitating the cable material particles by the device be accelerated by blowing the cable material particles to turn over through the upward airflow, but also the dust falling off when the cable material particles are agitated can be blown upwards, and then sucked away through the dust suction pipe preset above the device. This can not only prevent the site from being filled with smoke and dust, but also remove the floating dust generated during the agitation of the cable material particles in advance, facilitating the use stability of the subsequent functions of the device.

[0032] After the stirring of the cable material particles ends, it moves downward through the electric extension rod 18. Combining with the usage mode of the electric telescopic rod 21 extending downward, the insertion rod 16 moves downward until the top of the insertion rod 16 moves to the usage height position below the bottom of the sieve hole 14. At this time, the sieve hole 14 opens, and the cable material particles fall from the sieve hole 14 to the top of the lifting plate 15. At the same time, the rotation motor 20 is started, and the rotation motor 20 drives the lifting plate 15 to rotate. Through the rotation of the lifting plate 15, the cable particles falling on the lifting plate 15 can be swung around. The cable particles hitting the inner wall of the fixed cylinder 1 can cause the impurities remaining on the cable particles to be shaken off at the inner wall of the fixed cylinder 1 by means of impact. Subsequently, the cable particles roll downward on the inner wall of the fixed cylinder 1, and at this time, the dust suction fan connected to the third slot 9 is started. During the rolling process of the cable particles, the residual dust on the cable particles will pass through the filter screen on the inner wall of the fixed cylinder 1 and enter the inside of the fourth slot 19 and then be adsorbed and removed.

[0033] During the feeding process of the cable particles, at this time, by adjusting the position of the movable plate 4 in the feeding ring 26, and then by stirring the cable particles in the feeding ring 26 through the movable plate 4, the feeding fluency of the cable particles in the feeding ring 26 can be increased. At the same time, through this stirring method, the small-sized cable particles and large-sized cable particles in the feeding ring 26 can be stirred and separated, so that the separation of the large-sized cable particles and small-sized cable particles by the device is more thorough.

[0034] After the separation of the cable particles is completed, at this time, the insertion rod 16 moves upward inside the sieve hole 14, and the top of the insertion rod 16 rises to the position where it is at the same horizontal usage height as the top of the movable bottom plate 13. Subsequently, by extending the electric extension rod 18, the lifting plate 15 rises inside the feeding ring 26 until the top of the lifting plate 15 rises to the position where it is at the same horizontal usage height as the top of the feeding ring 26. Subsequently, the movable plate 4 rotates to the usage state perpendicular to the fixed rod 3, and by extending the electric lifting rod 6 downward, the bottom of the movable plate 4 abuts against the top of the movable bottom plate 13. Subsequently, by sliding the sliding electric slider 11 in the sliding groove 10, the movable plate 4 can scrape the cable particles on the movable bottom plate 13 and scrape the cable particles on the movable bottom plate 13 into the inside of the fixed ring 2, completing the automatic feeding of the cable particles on the movable bottom plate 13.

[0035] When the sieve hole 14 is blocked after the device has been used for a period of time, by moving the insertion rod 16 in the sieve hole 14, the automatic dredging of the sieve hole 14 can also be completed, increasing the functional use stability and use convenience of the device.

[0036] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
