[0028] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explaining the present invention and are not intended to limit the present invention.

[0029] The following is combined with Figures 1-8 This embodiment is described in further detail.

[0030] like Figure 1 and Figure 2As shown, a device for separating plastic parts and wood residue from waste furniture in this embodiment includes an inner shell 210 and an outer shell 100 covering the inner shell 210. A wind separation component is provided in the inner shell 210, a filter component is provided in the outer shell 100 and below the inner shell 210, and a cleaning component for cleaning filter residue discharged from the filter component is provided outside the outer shell 100 and at the bottom. The separation device in this embodiment can screen the mixture of crushed waste furniture wood to separate the plastic parts and wood residue in the mixture; Specifically, the inner shell 210 is fixed to the top of the outer shell 100, wherein the top of the outer shell 100 is formed with a feed port 103 connected to the inner shell 210, thereby allowing the mixed material to be screened to be added to the inner shell 210. The air separation component can air separate the mixed material entering the inner shell 210, so that the plastic parts and wood chips in the mixed material are screened and then enter the outer shell 100, and the wood residue with greater gravity is collected at the bottom of the inner shell 210; Among them, Figure 3 As shown, a notch 301 is provided on the side wall of the inner shell 210, and an openable and closable side door is provided at the notch 301, thereby facilitating the discharge of wood residues in the inner shell 210; of course, an opening and closing door is provided on one side surface of the outer shell 100 corresponding to the side door, so as to facilitate the maintenance of the equipment in the outer shell 100 and the discharge of wood residues in the inner shell 210; The filter assembly is provided to filter the plastic parts and wood chips that enter the housing 100, so that the wood chips are filtered and collected at the bottom of the housing 100, and the plastic parts are left on the filter assembly to form filter residue. The cleaning assembly is provided so that the filter residue remaining on the filter assembly can be discharged from the housing 100 and enter the cleaning assembly for cleaning, that is, the plastic parts can be cleaned to remove the wood chips attached thereto. Specifically, in order to discharge the wood chips at the bottom of the housing 100, a discharge hopper 201 is provided at the bottom of the housing 100. In order to install the discharge hopper 201, supporting feet 111 for supporting it are provided at the bottom of the housing 100.

[0031] In this embodiment, the air separation assembly includes baffles 220 spaced apart from top to bottom, an air inlet end is provided on one side of the inner shell 210, and a filter end is provided on the other side. A swing assembly for driving the baffles 220 to swing is provided outside the inner shell 210; In this embodiment, the air inlet end is an air duct 102 extending through the outer shell 100, and the filter end is a filter screen 302 provided on the other side of the inner shell 210. The baffles 220 are arranged relative to each other and staggered, and one side of the baffle 220 extends to the center of the inner shell 210. As a result, when the mixed material entering the inner shell 210 from the feed inlet 103 falls, it is blocked and rebounded by the baffle 220, which can extend the falling time of the mixed material in the inner shell 210. Specifically, the air duct 102 is connected to an existing fan, so that the air inlet end supplies air to the inner shell 210, and the plastic parts and wood chips in the falling mixed material are separated by air so that they can enter the outer shell 100 through the filter end. Among them, through the setting of the swing component, it can drive the baffle 220 to swing, which can impact the falling mixed material and then break up the mixed material, so as to improve the air separation effect of the air separation component on the mixed material.

[0032] In this embodiment, the filter assembly includes a filter plate 230 in the shape of a boss. A slag discharge port 101 is provided on the four side walls of the housing 100. The lower end of the filter plate 230 extends downward to form an extension portion 231 for blocking the slag discharge port 101. A lifting assembly is provided at the bottom of the housing 100 for driving the filter plate 230 to rise and fall to open the slag discharge port 101. The swing assembly is also used to drive the filter plate 230 to swing up and down. In this embodiment, the extension portion 231 slides against the inner wall of the housing 100 to ensure the filtering effect of the filter plate 230. The lifting assembly drives the filter plate 230 upward so that the extension portion 231 blocks the slag discharge port 101. At this time, the plastic parts and wood chips that enter the housing 100 fall due to gravity and fall onto the filter plate 230 for filtration. The wood chips are filtered by the filter plate 230 and discharged through the discharge hopper 201, while the plastic parts remain on the filter plate 230. When the lifting assembly drives the filter plate 230 to move downward, the extension portion 231 moves downward, and the slag discharge port 101 is opened. At this time, because the filtering surface of the filter plate 230 is in a boss shape, the plastic parts on the filter plate 230 roll toward the corresponding slag discharge port 101 under the action of gravity, and are then discharged therefrom; The filter plate 230 is driven to swing up and down by the swing assembly, thereby improving the filtering effect of the filter plate 230 on plastic parts and wood chips.

[0033] In this embodiment, the cleaning assembly includes a cleaning pool 110 arranged around the shell 100 and located at the bottom. An aeration assembly is provided in the shell 100. When the swing assembly is working, it is used to drive the aeration assembly to aerate the cleaning pool 110.

[0034] In this embodiment, the cleaning tank 110 stores cleaning liquid, wherein the plastic parts discharged from the slag discharge port 101 can enter the cleaning tank 110 so that the plastic parts can be immersed and cleaned; Wherein, by setting the aeration component, the swing component drives the aeration component to aerate the cleaning tank 110 to stir the cleaning liquid, thereby improving the immersion effect of the plastic parts.

[0035] Combine Figure 4-Figure 5 As shown, in this embodiment, a rotating shaft 501 extending through the inner shell 210 is provided on the opposite side walls of the baffle 220, and a sprocket 510 is provided at the protruding end of the rotating shaft 501. The sprockets 510 located in the upper and lower directions are connected by a chain 520. The swing assembly includes a lifting rod 240 located on opposite sides of the inner shell 210 and capable of being raised and lowered. A bracket 410 is provided on the lifting rod 240, and a rack 530 is provided on the bracket 410. A gear 540 meshing with the corresponding rack 530 is provided on the rotating shaft 501. A driving member for driving the lifting rod 240 to rise and fall is provided at the top inside the outer shell 100.

[0036] In this embodiment, a rotating shaft 501 is provided through opposite side walls of the inner shell 210 to achieve rotatable installation of the baffle 220 within the inner shell 210. The sprocket 510 and chain 520 are provided so that, in actual use, the baffles 220 on the same side of the inner shell 210 can swing synchronously. Among them, a gear 540 is provided on the rotating shaft 501 located at the same horizontal height, and the driving member drives the lifting rod 240 to rise and fall synchronously on the opposite sides of the inner shell 210, thereby driving the rack 530 to move up and down, driving the gear 540 to rotate forward and reverse, and then driving the rotating shaft 501 to rotate, thereby realizing the reciprocating swing of the baffle 220.

[0037] Combine Figure 6 As shown, in this embodiment, the driving member includes a mounting cylinder 400, in which a rotatable rotating shaft 610 and a lifting cylinder 620 sleeved on the rotating shaft 610 are provided. The lifting cylinder 620 is connected to the corresponding lifting rod 240 through a connecting rod 401 that passes through the mounting cylinder 400. The outer wall of the rotating shaft 610 is provided with a wavy sliding groove 611 connected end to end along its circumference. A sliding column sliding in the sliding groove 611 is relatively provided on the inner wall of the lifting cylinder 620. The rotating shaft 610 is rotated to drive the lifting cylinder 620 to rise and fall.

[0038] In this embodiment, the upper end of the mounting tube 400 is open, and the open end extends outward to form a flange portion, which is mounted on the top wall of the housing 100 by screws, thereby achieving the installation of the driving member; In actual use, a limiting groove is provided on the outer side wall of the connecting rod 401 along its axial direction, and a through hole is provided on the bottom wall of the mounting cylinder 400 for the connecting rod 401 to pass through. A limiting block is provided on the side wall of the through hole and slides in the limiting groove. Thus, the connecting rod 401 is restricted, and even the lifting cylinder 620 is restricted and cannot rotate circumferentially. The sliding groove 611 and the sliding post are arranged so that the rotation of the rotating shaft 610 can cause the side wall of the sliding groove 611 to squeeze the sliding post, thereby driving the lifting cylinder 620 to rise and fall in the installation cylinder 400, that is, to achieve the lifting and lowering of the lifting rod 240, thereby driving the baffle 220 to swing back and forth; In order to realize the rotation of the rotating shaft 610 , a motor 120 for driving the corresponding rotating shaft 610 to rotate is provided at the top end of the housing 100 .

[0039] In this embodiment, a tension spring 250 is provided at the bottom end of the inner shell 210 for pulling the filter plate 230 upward. The lower end of the lifting rod 240 abuts against the filter plate 230, and the lifting rod 240 is raised and lowered to drive the filter plate 230 to swing up and down.

[0040] Through the structure of this embodiment, in actual use, when the motor 120 drives the lifting rod 240 to rise and fall, it can drive the filter plate 230 to move downward, and cooperate with the pulling action of the tension spring 250 to drive the filter plate 230 to swing up and down, thereby better filtering and screening plastic parts and wood chips.

[0041] In this embodiment, a mounting portion 430 is provided on the extension portion 231 , and the lifting assembly includes a cylinder 260 . The output end of the cylinder 260 is provided with a threaded rod 261 passing through the mounting portion 430 , and a limiting nut is threadedly connected to the through end of the threaded rod 261 .

[0042] In this embodiment, the setting of the limiting nut allows, in actual use, when the cylinder 260 drives the threaded rod 261 to move upward, the limiting nut can avoid limiting the mounting portion 430. At this time, the tension spring 250 can pull the filter plate 230 upward, thereby causing the extension portion 231 to move upward to block the slag discharge port 101. At this time, the lifting rod 240 can be lifted and lowered to push the filter plate 230 to rock up and down. During this process, the extension portion 231 always blocks the slag discharge port 101. When the cylinder 260 drives the threaded rod 261 downward, the limit nut can be moved downward, so that it abuts the mounting portion 430 and drives the filter plate 230 downward, thereby opening the slag discharge port 101 so that the plastic parts can be discharged into the cleaning tank 110 through the slag discharge port 101.

[0043] Combine Figure 4-8As shown, in this embodiment, the aeration assembly includes an aeration tube 420 arranged at the bottom of the cleaning tank 110, and aeration holes are arranged on the aeration tube 420. The aeration assembly also includes an aeration component arranged in the outer shell 100, and the lifting rod 240 is raised and lowered to drive the aeration component to pump air into the aeration tube 420.

[0044] Through the structure of this embodiment, the lifting rod 240 can be raised and lowered to enable the aerator to supply air into the aeration pipe 420, thereby aerating the aeration holes, so as to disturb the cleaning liquid in the cleaning tank 110 and improve the cleaning effect of the plastic parts.

[0045] In this embodiment, the aerating component includes an air box 270 with an opening at the upper end, and a piston plate 710 that can be raised and lowered is provided in the air box 270. The piston plate 710 is provided with a connecting rod 701 that extends through the air box 270 and is connected to the lifting rod 240. An air supply pipe 130 connected to the aeration pipe 420 is provided at the bottom of the air box 270, and an air hole is provided on the piston plate 710, and an air inlet component that can be opened and closed is provided at the air hole.

[0046] In this embodiment, the air inlet member includes a blocking plate 810 provided on the lower side of the piston plate 710 through a torsion spring. The blocking plate 810 is used to seal the air hole. The upward movement of the piston plate 710 is used to drive the blocking plate 810 to rotate to open the air hole.

[0047] In this embodiment, two air pumping boxes 270 are provided on the same side of the inner shell 210, and are respectively located on both sides of the corresponding lifting rod 240. The two air pumping boxes 270 are provided to increase the air supply to the aeration pipe 420, thereby improving the aeration effect. The air box 270 is fixedly mounted on the inner wall of the housing 100. In actual use, the connecting rod 701 connects the piston plate 710 and the lifting rod 240, so that the lifting rod 240 can drive the piston plate 710 to move up and down in the corresponding air box 270. When the piston plate 710 moves upward in the air pumping box 270, the centrifugal force exerted on the blocking plate 810 can overcome the torsion force of the torsion spring, so as to rotate the blocking plate 810 away from the piston plate 710 to open the air hole, and enter the air pumping box 270 below the piston plate 710 to connect to the outside world, so as to allow outside air to enter and prevent the cleaning liquid from entering the air pumping box 270, so that the piston plate 710 moves downward and supplies air to the aeration pipe 420 again.

[0048] The present invention also provides a method for separating plastic parts and wood residue from waste furniture, which uses the above-mentioned device for separating plastic parts and wood residue from waste furniture and specifically includes the following steps: S1. Using existing crushing equipment to crush waste furniture wood to produce a mixed material; S2. The mixed material in step S1 is added into the inner shell 210 through the feed port 103. At this time, the motor 120 is started to drive the baffle 220 to swing back and forth in the inner shell 210, thereby impacting and breaking up the mixed material falling in the inner shell 210. At the same time, the fan is started to supply air from the air inlet end into the inner shell 210 to separate the mixed material, so that the plastic parts and wood chips enter the outer shell 100 through the filter end; S3. During step S2, the cylinder 260 is started to drive the threaded rod 261 upward, so that the filter plate 230 moves upward under the action of the tension spring 250, so that the extension portion 231 blocks the slag discharge port 101. At the same time, the motor 120 is started to drive the filter plate 230 to shake up and down, so that the filter plate 230 can better filter and screen the plastic parts and wood chips entering the housing 100, thereby separating the plastic parts and wood chips. S4. After the filter assembly has filtered for a period of time, the cylinder 260 is started to drive the threaded rod 261 downward, so that the filter plate 230 moves downward and the slag discharge port 101 is opened. At this time, the plastic parts on the filter plate 230 enter the cleaning tank 110 through the slag discharge port 101. After the slag discharge is completed, the cylinder 260 is started to drive the threaded rod 261 upward, so that the filter plate 230 is reset under the action of the tension spring 250, so that the plastic parts and wood chips can continue to be filtered and screened. S5. When the motor 120 is started, the lifting rod 240 can drive the piston plate 710 to move up and down in the air pump box 270, so that the aeration pipe 420 can aerate the cleaning tank 110, thereby improving the cleaning effect of the plastic parts in the cleaning tank 110.
