Description

Technical Field

[0001] This application relates to the field of waste collection, and in particular to a corrugated cardboard waste recycling device. Background Technology

[0002] Corrugated cardboard is a multi-layered adhesive, consisting of at least one layer of corrugated core paper (commonly known as "corrugated sheet," "corrugated paper," "corrugated core," "corrugated base paper") and one layer of cardboard, giving it high mechanical strength. Corrugated cardboard production often generates a lot of scrap material.

[0003] In related technologies, to recycle scrap materials, the scrap materials are fed into a crusher for crushing, and the crushed scrap materials are formed into corrugated paper pellets. The corrugated paper pellets are then moistened to form pulp, thus allowing the scrap materials of corrugated cardboard to be reused.

[0004] However, the process of crushing scrap materials in the crusher generates a large amount of dust from corrugated cardboard. Excessive dust in the factory can affect the health of construction workers. Summary of the Invention

[0005] To reduce dust in factories, this application provides a corrugated cardboard waste recycling device.

[0006] The corrugated cardboard waste recycling device provided in this application adopts the following technical solution:

[0007] A corrugated cardboard waste recycling device includes a duct, one end of which is fixedly connected to a dust collection hood. A suction fan is installed on the duct, and a filter plate is installed inside the duct. An opening is provided on the bottom wall of the duct near the filter plate. A collection box with an open top is connected to the opening. A locking component is connected to the collection box to lock it to the duct. A sealing plate is slidably connected to the upper opening of the collection box to seal it. An adjustment component is connected to the sealing plate to drive the sealing plate to slide and thus open or close the upper opening of the collection box.

[0008] By adopting the above technical solution, when the crusher is crushing scrap material, the dust collection hood is aligned with the crusher, and then the suction fan is started. At this time, the dust generated by the crusher is discharged from the factory along the duct. During this process, the filter plates intercept the dust, which then slides down the filter plates into the collection box, where it is collected. When it is necessary to clean the dust in the collection box, the locking assembly is adjusted to lock the collection box to the duct, and the sealing plate is slid relative to the collection box by adjusting the assembly, thereby sealing the upper opening of the collection box. The collection box is then separated from the duct. Thus, during the disassembly of the collection box, the dust inside is less likely to be stirred up again through the upper opening, reducing dust in the factory.

[0009] Preferably, the locking assembly includes outward-folding rods fixed to the two outer side walls of the collection box, and two mounting rods fixedly connected to the outer bottom wall of the air duct. The opening is located between the two mounting rods, and each of the two mounting rods has a insertion groove on one side wall that is close to each other. Each outward-folding rod is slidably inserted into a corresponding insertion groove.

[0010] By adopting the above technical solution, each outward-folding rod is aligned with the corresponding insertion slot. Then, the collection box is pushed towards the inside of the insertion slot so that each outward-folding rod slides into the corresponding insertion slot until each outward-folding rod is fully inserted into the corresponding insertion slot. At this time, the upper opening of the collection box is aligned with the through-hole, and the installation between the collection box and the air duct is completed. The operation is simple and convenient.

[0011] Preferably, the adjustment assembly includes sliders fixedly connected to the two side walls of the sealing plate, and sliding grooves are provided on the two opposing inner side walls of the collection box. Each slider is slidably connected to the corresponding sliding groove. Each sliding groove is provided with an adjustment spring. One end of the adjustment spring is fixedly connected to the slider, and the other end is fixedly connected to one side wall of the sliding groove. Adjustment grooves are provided on the opposite sides of the two outward-turning rods. An adjustment block is slidably connected in each adjustment groove. One adjustment block corresponds to one slider, and an adjustment rope is fixedly connected between the adjustment block and the slider. A driving block is fixedly connected to one end of each insertion groove. When the outward-turning rod is slidably inserted into the insertion groove, the driving block is slidably inserted into the adjustment groove and abuts against the corresponding adjustment block.

[0012] By adopting the above technical solution, the outward-folding rod is aligned with the corresponding insertion slot, and each driving block is aligned with the corresponding adjustment slot. The collection box is pushed towards the inside of the insertion slot, and the outward-folding rod gradually inserts into the insertion slot. At this time, the driving block gradually slides into the adjustment slot. The collection box is continued to be pushed until the driving block contacts the adjustment block, and the driving block pushes the adjustment block to slide along the adjustment slot. The movement of the adjustment block is caused by the adjusting rope pulling the slider in the opposite direction to the adjustment block. The movement of the slider causes the sealing plate to gradually move away from the collection box, thus opening the upper opening of the collection box and stretching the adjusting spring. When the collection box is pulled in the opposite direction, causing the outward-folding rod to gradually disengage from the insertion slot, the slider, under the force of the adjusting spring, causes the sealing plate to move towards the collection box until the sealing plate closes the upper opening of the collection box. Thus, when the collection box is installed with the duct, the sealing plate automatically opens the upper opening of the collection box; during the gradual disassembly of the collection box from the duct, the sealing plate automatically closes the upper opening of the collection box.

[0013] Preferably, a holding box is fixedly connected to the outer bottom wall of the air duct. The holding box is located on the side of each mounting rod away from the drive block. The side wall of the holding box near the mounting rod has a holding opening. When each outward-turning rod is inserted into the insertion slot, the sealing plate slides open the upper opening of the collection box, and the end of the sealing plate that slides out of the collection box is inserted into the holding box.

[0014] By adopting the above technical solution, during the process of connecting the outward-folding rod and the insertion slot, the sealing plate gradually moves away from the collection box and gradually inserts into the collection box from the holding opening. The setting of the collection box limits the occurrence of accidental contact with the sealing plate.

[0015] Preferably, the inner bottom wall of the container gradually slopes towards the air duct from the direction away from the mounting rod.

[0016] By adopting the above technical solution, during the process of gradually inserting the sealing plate and the holding box, the bottom wall of the holding box pushes the sealing plate to move closer to the air duct, and the sealing plate drives the collection box to move closer to the collection box, so that the upper edge of the collection box gradually presses against the outer bottom wall of the air duct, thus limiting the occurrence of leakage at the air duct opening.

[0017] Preferably, a connecting assembly is installed on the duct. The connecting assembly includes two support rods fixedly connected to the inner top wall of the duct. Several support grooves are opened on the side walls of the two support rods that are close to each other. A connecting block is slidably connected in each support groove. A support spring is installed between each connecting block and the bottom wall of the support groove. Several connecting grooves are opened at the upper end of the filter plate. One connecting block corresponds to one connecting groove, and one end of the connecting block is inserted into the connecting groove. The end of the connecting block that is inserted into the connecting groove is hemispherical.

[0018] By adopting the above technical solution, when cleaning the filter plate is required, pull the filter plate away from the top wall of the duct from the opening. The inner top wall of the connecting groove applies force to the connecting block, causing the hemispherical connecting block to gradually retract into the support groove and detach from it. Continue pulling the filter plate to complete the disassembly. This facilitates cleaning of the filter plate, and the method of disassembling and assembling the filter plate is simple, convenient, and easy to operate.

[0019] Preferably, the filter plate includes a filter frame and a filter screen installed in the middle of the filter frame. The filter plate is detachably connected to the air duct. A shielding assembly is installed on the filter plate. The shielding assembly includes two hollow storage rods fixedly connected to the bottom wall of the filter frame. A rotating shaft is rotatably connected inside each storage rod. A torsion spring is installed at one end of the rotating shaft. One end of the torsion spring is fixedly connected to the rotating shaft, and the other end is fixedly connected to the inner wall of the storage rod. A shielding curtain is wound around the rotating shaft. Each of the two storage rods has an elongated opening on its opposite side. One end of each shielding curtain passes through the corresponding elongated opening and extends out of the storage rod. The shielding assembly also includes a drive component for pulling the end of each shielding curtain extending out of the storage rod upward.

[0020] By adopting the above technical solution, when the filter panel needs to be disassembled, the drive unit pulls each shielding curtain to unroll it, and the end of each shielding curtain extending from the storage rod moves upward. In this way, the two shielding curtains on both sides of the filter panel can shield the filter screen in the middle of the filter panel, and the torsion spring is in a stored state. At this time, the filter panel is disassembled, which reduces the occurrence of dust adhering to the filter panel falling everywhere due to vibration during the disassembly process.

[0021] Preferably, the filter frame has two mounting chambers. Each mounting chamber has mounting holes on both sides of its upper end. Each curtain extends out of the storage rod and is fixedly connected to two drive ropes. The drive mechanism includes two drive ropes placed in each mounting chamber. The upper ends of the two drive ropes near the same end of the storage rod pass through the mounting holes and are fixedly connected to the same drive rope. One end of each drive rope extends downward through the inner bottom wall of the mounting chamber and is fixedly connected to a pull block. A magnet is fixedly connected to both sides of the upper end of the filter frame. Each curtain extends out of the storage rod and is fixedly connected to two magnets for attracting each other with the magnets.

[0022] By adopting the above technical solution, pulling down the two pull blocks causes each of the two pull blocks to unroll and move upward through each drive rope and each drive rope until magnet one and magnet two attract each other, at which point the curtain will cover the filter screen.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Reduced dust in the factory;

[0025] 2. As the collection box is gradually disassembled from the air duct, the automatic seal will close the upper opening of the collection box to reduce dust generation.

[0026] 3. It reduces the occurrence of dust adhering to the filter plates falling everywhere due to vibration during the disassembly process. Attached Figure Description

Detailed Implementation

[0034] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0035] This application discloses a corrugated cardboard waste recycling device. (Refer to...) Figure 1 and Figure 2 The recycling device includes a duct 1 for fixed installation on the factory ceiling. One end of the duct 1 is fixedly connected to a dust collection hood 2, and the other end extends into the factory. A suction fan 3 is installed on the duct 1, located at the end of the duct 1 furthest from the dust collection hood 2.

[0036] The duct 1 is equipped with three filter plates 4, which are arranged sequentially as a primary filter plate 4, a secondary filter plate 4, and a tertiary filter plate 4 in the direction away from the dust collection hood 2. Each filter plate 42 includes a filter frame 41 and a filter screen 42 installed in the middle of the filter frame 41. The filtration intensity of the primary filter plate 4, the secondary filter plate 4, and the tertiary filter plate 4 increases sequentially.

[0037] Three collection boxes 5 are installed on the lower surface of the duct 1, with each collection box 5 corresponding to a filter plate 4. The collection boxes 5 are located on the side of the filter plate 4 closest to the dust collection hood 2. The lower surface of the duct 1 has three openings 11. The upper surface of each collection box 5 is open. When each collection box 5 is installed on the duct 1, the upper opening of the collection box 5 is aligned with the opening 11 on the duct 1.

[0038] When the suction fan 3 is started, the dust collection hood 2 collects the dust generated during the crushing of corrugated cardboard by the crusher. The dust then enters the air duct 1 and is filtered by three filter plates 4. After the dust is filtered by the filter plates 4, the dust trapped on the filter plates 4 falls down into the corresponding collection box 5.

[0039] In order to increase the area of ​​the filter plate 4 for filtering dust, each filter plate 4 is set at an angle, and the dust intercepted by the filter plate 4 can easily slide down along the filter plate 4 into the collection box 5.

[0040] Reference Figure 2 and Figure 3 Each collection box 5 is equipped with a locking assembly 6 that locks the collection box 5 to the air duct 1. The locking assembly 6 includes outward-folding rods 61 fixedly connected to the two outer side walls of the collection box 5, and mounting rods 62 on both sides of each through hole. Each mounting rod 62 is fixedly connected to the outer bottom wall of the air duct 1. Insertion slots 621 are provided on the sides of the two mounting rods 62 that are close to each other. One outward-folding rod 61 corresponds to one insertion slot 621, and the outward-folding rod 61 and the insertion slot 621 are slidably inserted into each other.

[0041] Slide the collection box 5 laterally away from the opening 11. The collection box 5 drives each outward flipping rod 61 to gradually slide along the insertion groove 621 and disengage from one end of the insertion groove 621. This completes the disassembly of the collection box 5, making it easier to centrally clean the dust particles formed by the corrugated cardboard inside the collection box 5.

[0042] Then, during the disassembly of the collection box 5, the movement of the collection box 5 can easily cause the dust collected inside the collection box 5 to be stirred up again. In order to solve this problem, a sealing plate 51 is slidably connected to the upper opening of the collection box 5 to seal the upper opening of the collection box 5. An adjustment component 7 is connected to the sealing plate 51 to drive the sealing plate 51 to slide along the collection box 5, thereby opening or closing the upper opening of the collection box 5.

[0043] Reference Figure 3 and Figure 4 The collection box 5 has sliding grooves 52 on both inner side walls, and adjustment grooves 611 on the side walls of the two outward-turning rods 61 that are opposite to each other. Both the sliding grooves 52 and adjustment grooves 611 are arranged along the length of the outward-turning rods 61. Slider blocks 511 are fixedly connected to both side walls of the sealing plate 51. Each slider 511 corresponds to one sliding groove 52, and both sliders 511 are located at the same end of the sealing plate 51. Each slider 511 is slidably connected to the sliding groove 52. The adjustment assembly 7 includes an adjustment spring 71 installed in each sliding groove 52. One end of the adjustment spring 71 is fixedly connected to the slider 511, and the other end is fixedly connected to the side wall of the sliding groove 52 away from the adjustment block 72. When the sealing plate 51 seals the upper opening of the collection box 5, the adjustment spring 71 is in its normal state.

[0044] Each adjusting slot 611 is slidably connected to an adjusting block 72, with each adjusting block 72 located at the end of the adjusting slot 611 furthest from the slider 511. One adjusting block 72 corresponds to one slider 511, and each adjusting block 72 is connected to the adjacent slider 511 by an adjusting rope 73, one end of which is fixedly connected to the adjusting block 72, and the other end to the slider 511. Each insertion slot 621 is fixedly connected to a driving block 74, located at one end of the insertion slot 621.

[0045] Place the collection box 5 on the side of each mounting rod 62 near the drive block 74, then align each outward-folding rod 61 with the corresponding insertion slot 621, and align the drive block 74 in each insertion slot 621 with the corresponding adjustment slot 611. Then push the collection box 5 towards the inside of the insertion slot 621, and each outward-folding rod 61 gradually inserts into the corresponding insertion slot 621.

[0046] Simultaneously, each drive block 74 slides into its corresponding adjustment slot 611. After entering the adjustment slot 611, the drive block 74 gradually pushes the adjustment block 72 to slide along the adjustment slot 611. The movement of the adjustment block 72 pulls the slider 511 gradually away from the adjustment spring 71 through the adjustment rope 73, stretching the adjustment spring 71. The movement of the slider 511 causes the sealing plate 51 to gradually move away from the collection box 5 until the outward flip rod 61 is fully inserted into the insertion slot 621. At this time, the sealing plate 51 slides to one end of the collection box 5, the upper opening of the collection box 5 is opened, and the opening of the collection box 5 is aligned with the through-hole 11.

[0047] In the event that the sealing plate 51 is accidentally touched, causing it to close the opening of the collection box 5, three holding boxes 75 are fixedly connected to the outer bottom wall of the duct 1. Each holding box 75 corresponds to one collection box 5, and each holding box 75 is located on the side of the pair of mounting rods 62 away from the drive block 74. A holding opening 751 is provided on the side wall of the holding box 75 near the pair of mounting rods 62, and the holding opening 751 extends through the interior of the holding box 75.

[0048] Reference Figure 2 and Figure 3 After each outward-folding rod 61 is inserted into the corresponding insertion slot 621, the end of the sealing plate 51 extending out of the collection box 5 is inserted into the holding box 75 from the holding port 751, and the holding box 75 restricts accidental contact with the sealing plate 51.

[0049] The inner bottom wall of each holding box 75 is sloped, gradually sloping towards the air duct 1 away from the pair of mounting rods 62. As the sealing plate 51 is gradually inserted into the holding box 75, the bottom wall of the holding box 75 pushes the sealing plate 51 to move towards the air duct 1. The movement of the sealing plate 51, in turn, drives the collecting box 5 to gradually press against the outer bottom wall of the air duct 1, thereby reducing the occurrence of large gaps between the upper surface of the collecting box 5 and the outer bottom wall of the air duct 1.

[0050] Reference Figure 1 and Figure 5 In order to facilitate the cleaning of the filter plate 4, a connecting component 8 is connected to the air duct 1 to lock the filter plate 4 to the air duct 1.

[0051] Three pairs of support rods 81 are fixedly connected to the inner top wall of the duct 1, and each pair of support rods 81 corresponds to a filter plate 4. On the side of the two support rods 81 in a pair that are close to each other, multiple support grooves 811 are provided. The connecting assembly 8 includes a connecting block 82 that slides into each support groove 811. Each support groove 811 is provided with a support spring 83. One end of the support spring 83 is fixedly connected to the connecting block 82, and the other end is fixedly connected to the bottom wall of the support groove 811.

[0052] Each filter frame 41 has multiple connecting slots 411 on both sides of its upper end. The upper end of the filter frame 41 is inserted between one end support rod 81. One connecting slot 411 is aligned with one support slot 811, and one end of the connecting block 82 is inserted into the connecting slot 411, while the other end remains in the connecting slot 411. Each connecting slot 411 is hemispherical, and the end of each connecting block 82 facing away from the bottom of the support slot 811 is also hemispherical.

[0053] When it is necessary to disassemble the filter plate 4, pull the filter plate 4 away from the support rod 81 from the opening 11. This causes the connecting block 82 to move relative to the connecting groove 411. The inner wall of the connecting groove 411 abuts against the connecting block 82, thereby pushing the connecting block 82 gradually into the support groove 811 and then out of the connecting groove 411, compressing the support spring 83. In this way, the filter plate 4 can be disassembled, which is simple and convenient.

[0054] When the filter plate 4 needs to be installed, push the filter plate 4 between a pair of support rods 81. The filter plate 4 pushes each connecting block 82 toward the inside of the support groove 811 until the connecting block 82 is completely inserted into the support groove 811. At this time, continue to push the filter plate 4 between the pair of support rods 81 until each support groove 811 is aligned with the corresponding connecting groove 411. In this way, each connecting block 82 is inserted into the corresponding connecting groove 411 under the force of the support spring 83.

[0055] Reference Figure 6 During the disassembly of filter plate 4, dust that remains on filter plate 4 may fall everywhere. To reduce the occurrence of this situation, each filter plate 4 is equipped with a shielding component 9.

[0056] The shielding assembly 9 includes two storage rods 91 fixedly connected to the bottom wall of the filter frame 41. Each storage rod 91 is a hollow structure, and the two storage rods 91 are stacked and fixedly connected to each other. A rotating shaft 92 is rotatably connected inside each storage rod 91. A torsion spring 93 is sleeved on one end of each rotating shaft 92. One end of the torsion spring 93 is fixedly connected to the rotating shaft 92, and the other end is fixedly connected to an inner wall of the storage rod 91.

[0057] Each rotating shaft 92 is wrapped with a shielding curtain 94. Each of the two storage rods 91 has an elongated opening 911 on one side wall facing away from each other. One end of each shielding curtain 94 extends from the corresponding elongated opening 911 onto the storage rod 91 and is fixedly connected to a sealing rod 95, which is used to block the corresponding elongated opening 911. A drive component 96 is connected to the filter frame 41 to pull the two sealing rods 95 upwards.

[0058] By pulling the two sealing rods 95 upwards via the drive component 96, the two sealing plates move upwards, which in turn pulls each shielding curtain 94 to gradually unroll and cover the filter screen 42. Each torsion spring 93 gradually accumulates power. When the two shielding curtains 94 sandwich the filter screen 42 in the middle and cover it, the filter plate 4 can be removed at this time to reduce the occurrence of dust falling from the filter plate 4.

[0059] The filter frame 41 has two mounting chambers 412, and the filter screen 42 is located between the two mounting chambers 412. Mounting holes 413 are provided on both sides of the upper end of each mounting chamber 412. The driving component 96 includes a driving rope 961 fixedly connected to both ends of each sealing rod 95, and a driving rope 962 provided in each mounting chamber 412. Each driving rope 961 corresponds to one mounting hole 413. Each driving rope 961 extends upward and passes through the corresponding mounting hole 413. One end of each of the two driving ropes 961 at the same end of the two sealing rods 95 is fixedly connected to the upper end of the driving rope 962. Each driving rope 962 extends downward along the mounting chamber 412 and passes through the bottom wall of the mounting chamber 412. A pull block 963 is fixedly connected to one end of each driving rope 962 extending out of the mounting chamber 412. Each filter screen 42 has a magnet 964 fixedly connected to both sides of its upper end, and each sealing rod 95 has two magnets 965 fixedly connected to its upper surface.

[0060] At the same time, pull down the two pull blocks 963. The two pull blocks 963 pull each sealing rod 95 gradually rise through each drive rope 962 and each drive rope 961 until the two magnets 965 and the corresponding magnet 964 on each sealing rod 95 attract each other. At this time, the pull blocks 963 can be released, and each shielding curtain 94 will cover the filter screen 42.

[0061] The implementation principle of the corrugated cardboard waste recycling device in this application embodiment is as follows: When it is necessary to disassemble the collection box 5, the collection box 5 is pulled away from the corresponding holding box 75. The collection box 5 drives each mounting rod 62 to gradually move away from the inside of the insertion slot 621. At this time, each adjusting spring 71 applies force to the corresponding slider 511, causing the slider 511 to drive the sealing plate 51 to gradually move away from the inside of the holding box 75. When the collection box 5 is disengaged from the mounting rod 62, the sealing plate automatically seals the upper opening of the collection box 5. At this time, the collection box 5 and the air duct 1 can be completely disassembled.

[0062] When the collection box 5 is detached from the air duct 1, and it is necessary to clean the dust inside the collection box 5, simply pull the sealing plate 51 away from the collection box 5 to open the upper opening of the collection box 5.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
