Description

Technical Field

[0001] This invention relates to the field of waste recycling equipment technology, and more specifically to a dismantling device for recycling waste electrical appliances. Background Technology

[0002] After waste electrical appliances are recycled, they need to be crushed and dismantled to facilitate the subsequent collection of valuable metal and non-metal materials. To facilitate the crushing and dismantling of waste electrical appliances, workers often use crushing equipment to crush them under existing technology. However, existing waste electrical appliance recycling and dismantling devices still have the following shortcomings in actual use. First, when using existing crushing and dismantling devices, the electrical components often generate a large amount of dust and debris during the crushing process. This dust and debris need to be removed by a dust collection device. As this dust and debris adheres to the dust collection holes, the size of the dust collection holes gradually decreases or even becomes completely blocked as the dust collection work progresses, thus affecting the dust collection work. Secondly, under the existing technology, after dismantling waste electrical appliances, the metal and non-metal materials are often mixed together, which is inconvenient for subsequent separation. The existing technology does not have the effect of initial separation of the materials after crushing and dismantling. Therefore, in order to solve the above problems, there is a need to provide a dismantling device for recycling waste electrical appliances. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a dismantling device for recycling waste electrical appliances, so as to solve the problems existing in the background art.

A closing door is movably installed on the feeding port via the side shafts. A front magnetic suction strip is provided on the closing door, and a rear magnetic suction strip is provided on the feeding port. When the closing door is closed, the front and rear magnetic suction strips attract each other. A cavity is provided inside the other side of the dust collection cover chamber. Dust collection holes are evenly distributed and located on the inner side of the cavity of the dust collection cover chamber. A dust collection box is fixedly installed on the outer side of the dust collection cover chamber, and the internal space of the dust collection box communicates with the cavity of the dust collection cover chamber. A filter plate is installed inside the dust collection box, and an exhaust fan is installed on the bottom outer side of the dust collection box. Sealing plates are installed on both sides of the dust collection box.

[0009] Furthermore, the cavity of the dust collection cover is provided with a track groove, which passes through the dust collection holes in the same row. The side through holes are opened and connected between the dust collection holes, and a through groove is opened and connected between the side through holes and the track groove.

[0010] Furthermore, a cavity slide is movably sleeved inside the cavity of the dust collection cover, and the back-blowing hole is opened on the inner side of the cavity slide and corresponds to the dust collection hole in the same row. A rail is fixedly installed outside the back-blowing hole, and the rail is movably sleeved with the rail groove. A blow groove is opened on the rail.

[0011] Furthermore, the cavity slide has arc-shaped telescopic folding plates at the upper and lower ends on both sides of the dust collection cover. An air pump is fixedly installed on one side of the dust collection cover, and an air pipe is fixedly connected to the output end of the air pump. The air pipe is connected to the cavity slide and communicates with its internal space. A support rod is fixedly connected to the outer end of the cavity slide on the other side of the dust collection cover. A connecting plate is fixedly sleeved on the support rod. A servo motor is fixedly installed on this side of the dust collection cover. The drive shaft of the servo motor is fixedly sleeved on the connecting plate. The drive shaft of the servo motor is located at the center of the arc of motion of the cavity slide.

[0012] Furthermore, the upper and lower ends of the connecting plate are provided with contactors, and the upper and lower outer sides of the dust collection cover are equipped with contact switches. The contact switches are electrically connected to the servo motor. When the contact switch is triggered by the contactor on the same side, the rotation direction of the drive shaft of the servo motor is changed.

[0013] Furthermore, the sorting component includes a discharge bin, which is fixedly installed at the bottom of the crushing chamber. A horizontal blowing groove is provided on one side wall of the discharge bin, and a blower box is installed on the outer side of the horizontal blowing groove. A permeable plate is provided on the other side wall of the discharge bin. A bottom material bin is fixedly installed at the bottom of the discharge bin, and the bottom material bin has three adjacent arc grooves. A partition plate is provided between the arc grooves. An installation plate is fixedly installed at the outer end of the bottom material bin. A push motor corresponding to the arc groove is installed on the outer side of the installation plate.

The support plate is fixedly installed at the bottom of the discharge bin. A collection box is fixedly installed at the bottom of the discharge bin, and the collection box is connected to the discharge end of the arc groove of the bottom material bin.

[0014] The technical effects and advantages of this invention are as follows: When dust and debris are sucked in through the suction hole, they tend to adhere to the hole walls. The air pump blows air into the cavity slide through the air pipe, and the airflow blows out from the back-blowing hole. The servo motor drives the cavity slide to reciprocate in the suction cover cavity through the connecting plate. When the back-blowing hole moves to align with the suction hole, the airflow blows out in the opposite direction from the suction hole along its hole direction. When the back-blowing hole moves between adjacent suction holes, the airflow blows out from the blow groove and enters the side through hole through the through groove, thus blowing out on both sides of the suction hole wall. By combining back-blowing and side-blowing, the dust and debris adhering to the suction hole wall are thoroughly blown away, thereby preventing the hole diameter from decreasing or even becoming blocked. When small raw materials generated from the crushing and dismantling of waste electrical appliances fall downwards through the gaps, the blower box blows air into the material hopper through the horizontal blowing channel, forming an air curtain. As the raw materials fall through the air curtain, heavier metal materials are blown along a shorter path, while lighter non-metal materials are blown along a longer path, causing them to fall into the three arc grooves at the bottom. The push motor drives the stacked screw shaft to rotate, thereby pushing these materials to accumulate and collect in the collection box. In this way, the device achieves the initial material separation function. Attached Figure Description

When the closing door 304 is closed, the front magnetic suction strip 305 and the rear magnetic suction strip... 306 are mutually adsorbed. A cavity is opened inside the other side of the dust collection cover 301. The inner side of the cavity of the dust collection cover 301 is provided with uniformly distributed dust collection holes 307. A dust collection box 308 is fixedly installed on the outside of the dust collection cover 301. The internal space of the dust collection box 308 is connected to the cavity of the dust collection cover 301. A filter plate 309 is installed inside the dust collection box 308. An exhaust fan 310 is installed on the bottom outside of the dust collection box 308. Sealing plates 311 are installed on both sides of the dust collection box 308. When the device is in use, when dust and debris are generated during the crushing and dismantling of waste electrical appliances, the exhaust fan 310 exhausts the exhaust to the outside. The dust and debris are sucked into the dust collection box 308 through the dust collection hole 307 and are intercepted and filtered by the filter plate 309. In this way, the dust collection effect during the crushing and dismantling of waste electrical appliances is achieved.

[0021] Reference Figures 5-10 The cavity of the dust collection cover 301 is also provided with a track groove 312. The track groove 312 passes through the dust collection holes 307 in the same row. The dust collection holes 307 are connected by a side through hole 313. A through groove 314 is opened and connected between the side through hole 313 and the track groove 312.

The upper and lower outer sides of the dust collection cover 301 on this side are equipped with contact switches 326. The contact switches 326 are electrically connected to the servo motor 324. When the contact switch 326 is triggered by the contactor 325 on the same side, it changes the rotation direction of the drive shaft of the servo motor 324. When the device is in use, when dust and debris are sucked in through the suction hole 307, these dust and debris easily adhere to the wall of the suction hole 307. The air pump 320 blows air into the cavity slide strip 315 through the air pipe 321, and the airflow blows outward from the back-blowing hole 316. The servo motor 324 drives the cavity slide strip 315 to reciprocate in the cavity of the dust collection cover 301 through the connecting plate 323. When the back-blowing hole 316 moves to be aligned with the suction hole 307, The airflow will blow out in the opposite direction from the suction hole 307 along its hole direction. When the back-blowing hole 316 moves to the position between the adjacent suction holes 307, the airflow will blow out from the blow groove 318 and enter the side through hole 313 through the through groove 314, thereby blowing out on both sides of the hole wall of the suction hole 307. By combining back-blowing and side-blowing, the dust and debris adhering to the hole wall of the suction hole 307 are fully blown away, thereby preventing the hole diameter from decreasing or even becoming blocked.

The collection box 411 is connected to the discharge end of the arc groove of the bottom material bin 405. When the device is in use, as small raw materials generated from the crushing and dismantling of waste electrical appliances fall downwards through the gaps, the blower box 403 blows air into the inside of the material drop hopper 401 through the horizontal blowing groove 402, forming an air curtain. When the raw materials fall through the air curtain, the heavier metal materials are blown along a shorter path, while the lighter non-metal materials are blown along a longer path, so that they fall into the three arc grooves at the bottom respectively. The push motor 408 drives the stacked screw shaft 409 to rotate, thereby pushing these materials to accumulate and collect in the collection box 411. The device achieves the initial material separation function in the above manner.

[0023] The working principle of this invention is as follows: When the device is in use, waste electrical appliances are put into the crushing box 101. The crushing motor 204 drives the drive shaft 203 to rotate the rotating shaft 103. Under the transmission action of the driven gear 201 and the drive gear 202, the crushing teeth 104 on the two rotating shafts 103 rotate towards each other, thereby crushing the waste electrical appliances on them. The crushed material leaks downward from the gaps between the crushing teeth 104 and the side teeth 102. When waste electrical appliances generate dust and debris during crushing and dismantling, the exhaust fan 310 exhausts the exhaust to the outside. The dust and debris are sucked into the dust collection box 308 through the dust collection hole 307 and are intercepted and filtered by the filter plate 309. This method achieves the dust collection effect during the crushing and dismantling of waste electrical appliances. When dust and debris are sucked in through the suction hole 307, these particles easily adhere to the walls of the suction hole 307. The air pump 320 blows air into the cavity slide 315 through the air pipe 321, and the airflow is blown outwards from the back-blowing hole 316. The servo motor 324 drives the cavity slide 315 to reciprocate within the cavity of the suction cover 301 via the connecting plate 323. When the back-blowing hole 316 moves to align with the suction hole 307, the airflow will... The airflow blows out in the opposite direction from the suction hole 307 along its hole direction. When the back-blowing hole 316 moves to a position between adjacent suction holes 307, the airflow blows out from the blow groove 318 and enters the side through hole 313 through the through groove 314, thereby blowing out on both sides of the hole wall of the suction hole 307. By combining back-blowing and side-blowing, the dust and debris adhering to the hole wall of the suction hole 307 are fully blown away, thereby preventing the hole diameter from decreasing or even becoming blocked. When small raw materials generated from the crushing and dismantling of waste electrical appliances fall downwards through the gaps, the blower box 403 blows air into the material drop hopper 401 through the horizontal blowing groove 402, forming an air curtain. When the raw materials fall through the air curtain, the heavier metal materials are blown along a shorter path, while the lighter non-metal materials are blown along a longer path, so that they fall into the three arc grooves at the bottom respectively.
