[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] like Figures 1-3The lamp tube recycling and processing device shown includes a processing box 1, a tube crushing mechanism 2, a discharge pipe 4, and a slag conveyor belt 6. The processing box 1 is used to process lamp tubes. The processing box 1 has a tube crushing working chamber 11 inside. During operation, the lamp tubes are first piled up in the tube crushing working chamber 11. The tube crushing mechanism 2 is installed in the tube crushing working chamber 11 and can crush the lamp tubes (mainly the glass tube body). The discharge pipe 4 is connected to the bottom of the processing box 1 and can communicate with the tube crushing working chamber 11. The processed material is output through the discharge pipe 4. The processed material includes unbreakable lamp heads and broken lamp tube glass shards. These two are not processed together. Therefore, this invention has a screening mechanism 5 installed in the middle section of the discharge pipe 4 to screen the slag. The sorting mechanism 5 separates the large, unbreakable lamp holders from the broken glass fragments of the lamp tubes. The fragment conveyor belt 6 is installed below the outlet of the discharge pipe 4. The sorted glass fragments continue to fall down the discharge pipe 4 and finally land on the fragment conveyor belt 6 for centralized output. The large lamp holders are intercepted and separated by the sorting mechanism 5. This invention can efficiently complete the pre-processing of lamp tubes and effectively separate the glass fragments and large lamp holders. This invention has the advantages of high processing efficiency and good screening effect, and can well meet the application needs of enterprises in lamp tube recycling. This invention is generally used for the recycling of fluorescent tubes, and can also be used for the recycling of other lamp tube products with similar fluorescent tube structures (lamp tube products whose main body is a lamp holder and a glass tube body).
[0022] The processing of lamps generates some waste gas, which cannot be directly discharged into the external environment. Therefore, such as Figure 2 As shown, a waste gas processor 3 is installed on the top of the treatment box 1. The waste gas processor 3 is connected to the tube crushing chamber 11. The waste gas processor 3 generates negative pressure to extract the waste gas generated during the lamp tube processing. Figure 1 As shown, a sealing door 12 is movably installed on the front of the processing box 1. When the sealing door 12 is opened, the lamp tube product to be processed is placed in. After the sealing door 12 is closed, the front of the tube crushing working chamber 11 is sealed. The top and back of the tube crushing working chamber 11 are sealed, and the bottom is sealed by the tube crushing mechanism 2. With the front sealing, a closed working environment is formed inside the tube crushing working chamber 11, which facilitates the exhaust gas processor 3 to extract and remove the exhaust gas.
[0023] like Figure 2As shown, the pipe crushing mechanism 2 includes a pressure plate assembly 21 and a base plate assembly 22. The pressure plate assembly 21 includes a pressing cylinder 211 and a pressing plate 212. The pressing cylinder 211 is vertically installed on the top of the processing box 1. The pressing plate 212 is disposed in the pipe crushing working chamber 11. The size of the pressing plate 212 matches the transverse cross-sectional size of the pipe crushing working chamber 11. The pressing plate 212 is connected to the piston rod end of the pressing cylinder 211. When the piston rod of the pressing cylinder 211 extends or retracts, it can drive the pressing plate 212 to move up and down. The base plate assembly 22 includes a guide plate seat 221, a base plate 222, and a translational cylinder 223. The guide plate seat 221 is fixedly installed on the side wall of the processing box 1. The base plate 222 is laterally matched and inserted into the guide plate seat 221. The guide plate seat 221 plays a role in guiding the movement of the base plate 222. A single-point support is provided. The translational push cylinder 223 is horizontally mounted on the top of the processing box 1. A linkage rod 224 is vertically connected to the base plate 222. The top end of the linkage rod 224 is connected to the piston rod end of the translational push cylinder 223. The extension and retraction of the piston rod of the translational push cylinder 223 acts on the base plate 222 through the linkage rod 224, allowing the base plate 222 to move laterally. When the piston rod of the translational push cylinder 223 retracts, the base plate 222 can pass through the guide plate seat 221 and move into the tube-breaking working chamber 11. Finally, the base plate 222 can close the bottom of the tube-breaking working chamber 11. The extrusion plate 212 is located above the base plate 222. Lamp tube products are stacked on the base plate 222. Driving the extrusion plate 212 downwards can extrude and break the glass tube of the lamp tube. To ensure the stable installation of the base plate 222, such as... Figure 2 As shown, a bottom support strip 225 is installed inside the tube crushing chamber 11. The bottom support strip 225 is located on the opposite side of the guide plate seat 221. After the bottom plate 222 moves into position, one end of the bottom plate 222 can rest on the bottom support strip 225. The bottom support strip 225 and the guide plate seat 221 provide two-point support below the bottom plate 222, ensuring the stability of the bottom plate 222. The bottom of the tube crushing chamber 11 is designed to be open. After the bottom plate 222 moves into position, it can close the bottom opening of the tube crushing chamber 11. At this time, the discharge pipe 4 is not connected to the tube crushing chamber 11. At this time, the lamp tube crushing operation can be performed. The downward movement of the extrusion plate 212 does not need to contact the bottom plate 222; it only needs to move down to crush the glass tube. During this process, the glass tube... The glass tube is crushed into fragments, while the lamp head component retains its basic shape (this is because lamp heads are generally made of plastic or metal). The final product is a mixture of glass fragments and the lamp head component. After the tube crushing operation, the base plate 222 moves outward from the processing box 1, and the discharge pipe 4 gradually connects with the tube crushing chamber 11. The product on the base plate 222 falls into the discharge pipe 4. The extrusion plate 212 of this invention is a frame plate welded from grid strips. This has two advantages: firstly, the grid strips have a small working area, making it easier to compress the glass tube; secondly, the grid plate has many holes, allowing the exhaust gas generated during the tube crushing operation to rise along the holes and be extracted by the exhaust gas processor 3.
[0024] like Figure 2 As shown, the discharge pipe 4 includes a screening section 41 and an outlet section 42. The screening section 41 is located in the middle of the discharge pipe 4, and the outlet section 42 is connected below the screening section 41. The screening section 41 is vertically installed to facilitate the installation of the screen 51. The screen 51 is horizontally fixed inside the screening section 41. The screen 51 is designed to allow glass fragments to pass through, but to trap large lamp head wastes. The outlet section 42 is inclined, and the inclination is intended to allow the screened glass fragments to slide down onto the fragment conveyor belt 6 below for collection. The output screening mechanism 5 includes a screen 51 and a screen cleaning assembly 52. The screen cleaning assembly 52 is installed above the screen 51 and can clean the screen surface of the screen 51 and remove the large lamp head parts that are trapped. The screen cleaning assembly 52 includes a screen cleaning push cylinder 521 and a vertical plate 522. The screen cleaning push cylinder 521 is installed on the outer wall of the screening section 41, and the vertical plate 522 is connected to the piston rod end of the screen cleaning push cylinder 521. The vertical plate 522 contacts the screen surface of the screen 51, and can clean the screen surface of the screen 51 as the vertical plate 522 moves. Figure 3 As shown, a large item outlet 411 is provided on the outer wall of the screening section 41. The vertical plate 522 can move towards the large item outlet 411 by the screen cleaning push cylinder 521. A large item recycling hopper 53 is installed on the outer wall of the outlet section 42. The large item recycling hopper 53 is connected to the large item outlet 411. The large items of lamp heads intercepted by the screen 51 can be pushed to the large item outlet 411 for output by the movement of the vertical plate 522. Finally, they are recycled into the large item recycling hopper 53. A hopper base 421 is installed on the outer wall of the outlet section 42. The hopper base 421 plays the role of installing and fixing the large item recycling hopper 53. The large item recycling hopper 53 is clamped in the hopper base 421. A handle 531 is connected to the outer wall of the large item recycling hopper 53. The large item recycling hopper 53 can be easily lifted and moved by the handle 531.
