Description

Technical Field

[0001] This invention relates to the field of waste treatment technology, and more particularly to a sorting device for waste treatment. Background Technology

[0002] Garbage is waste generated in human daily life and production. Due to its large volume, complex and diverse composition, and polluting nature, proper garbage disposal is necessary. Garbage disposal involves sorting garbage, quickly removing it, treating it to render it harmless, and finally making it reasonable. Garbage sorting is divided into many types, classified according to size, material, shape, etc. In the market, most sorting is still done manually, which is both time-consuming and labor-intensive.

[0003] With the development of waste treatment technology, waste sorting operations no longer rely heavily on manual labor. However, most existing sorting devices crush the waste before applying magnetic adsorption, and often use fixed magnetic plates or unidirectional rotating stirring structures. This makes it easy for magnetic materials in the waste to be encapsulated by non-magnetic impurities or deposited at the bottom, resulting in insufficient contact between the electromagnet and the magnetic materials. This reduces the sorting rate of waste containing magnetic materials. Secondly, existing technologies rely on gravity drainage or static filtration, which increases the time required for liquid separation for kitchen waste and sludge components with high water content. Furthermore, the solid residue after separation still has a high water content, which increases the energy consumption of subsequent processing. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing technology has the disadvantages of incomplete sorting of magnetic materials, low efficiency of liquid and solid separation, and poor coordination of multiple mechanisms.

[0006] A magnetic sorting and agitating mechanism is fixed above the top frame. The magnetic sorting and agitating mechanism is connected to the stirring roller and hinged to the electromagnet. The magnetic sorting and agitating mechanism drives the stirring roller to perform longitudinal reciprocating movement and cyclic rotation synchronously. Through the rotation and agitation of the stirring roller, the electromagnet is linked to perform up and down reciprocating movement to adsorb and sort magnetic substances in the waste to be processed.

[0007] The liquid sorting mechanism is fixedly installed on the top frame and located on the side of the magnetic sorting and stirring mechanism away from the elevator. The liquid sorting mechanism cooperates with the stirring roller so that when the stirring roller rotates, it abuts and squeezes the liquid sorting mechanism, and the liquid substances in the waste to be processed are collected through the outlet of the water group.

The pusher plate is slidably attached to the inner wall of one side of the pusher slot.

[0028] The technical effects and advantages of this invention are as follows:

[0029] In this invention, the magnetic sorting and agitation mechanism drives the threaded rod 11 to rotate via a second motor, causing the sliding sleeve inclined rod to move longitudinally along the smooth rod. Simultaneously, the drive gear on the sliding sleeve inclined rod meshes with the toothed plate, driving the stirring roller to rotate cyclically via a belt, forming a composite motion trajectory of "longitudinal movement + circumferential agitation". At the same time, the silicone pad on the stirring roller rod penetrates into the waste layer for flexible agitation, avoiding waste clumping caused by hard agitation. When the drive gear rotates, it links the upper and lower movable frames via a hinged drive rod, causing the electromagnet under the cross frame plate to move up and down along the limiting slide groove. This, combined with the longitudinal movement of the sliding sleeve inclined rod, forms a magnetic attraction path of "dynamic scanning + vertical oscillation". This structure effectively solves the technical defects of existing static magnetic attraction devices, such as magnetic materials being easily encapsulated and deposited by non-magnetic waste and insufficient contact with the magnetic attraction elements.

[0030] In this process, due to the linkage of the hinged drive rod, when one of the sub-rods of the mixing roller stirs the waste layer to the top, the hinged drive rod drives the electromagnet to move downward, thereby shortening the distance to the waste layer and further improving the efficiency of magnetic sorting.

[0031] In this invention, the liquid sorting mechanism adopts a mechanical extrusion mode in which the stirring rollers agitate against the extrusion plate. This allows a portion of the waste layer to be continuously extruded against the extrusion plate while the stirring rollers agitate against it. The pressure is provided by the springs, and in conjunction with the flow guiding structure of the water-spraying platform, the free liquid in the waste is quickly separated through the outlet of the water effluent group. This helps to reduce the moisture content of the solid residue after separation and reduce the subsequent incineration or landfill treatment costs.

[0032] In this invention, the feeding hood of the crushing mechanism is directly connected to the inclined cylinder of the solid sorting mechanism. The crushing wheel assembly and the spiral feeding component form an integrated process of "crushing-conveying-grading", which realizes the precise grading of solids of different particle sizes. Furthermore, by linking various motors and hydraulic cylinders through the operation panel, the "lifting-magnetic sorting-liquid sorting-crushing-solid sorting" process can be started with one click, reducing manual intervention and lowering labor costs.

Detailed Implementation

[0048] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments.

[0049] Reference Figures 1 to 14 As shown, the present invention provides a technical solution: a sorting device for waste treatment, including a sorting body 1, an operation panel 3, a hoist 5 and a first motor 4 are fixedly installed on one side surface of the sorting body 1, the output end of the first motor 4 is fixedly connected to the drive end of the hoist 5, a top frame 2 is fixedly installed on the upper center surface of the sorting body 1, and the surface of the top frame 2 is respectively provided with a feed inlet 6 and a water outlet 20. The sorting device for waste treatment also includes a stirring roller 15 and an electromagnet 19.

[0050] A magnetic sorting and stirring mechanism is fixed above the top frame 2. The magnetic sorting and stirring mechanism is connected to the stirring roller 15 and hinged to the electromagnet 19. The magnetic sorting and stirring mechanism drives the stirring roller 15 to perform longitudinal reciprocating movement and rotation in sync. Through the rotation and stirring action of the stirring roller 15, the electromagnet 19 is linked to perform up and down reciprocating movement to adsorb and sort magnetic substances in the waste to be processed.

[0051] The liquid sorting mechanism is fixedly installed on the top frame 2 and located on the side of the magnetic sorting and stirring mechanism away from the elevator 5. The liquid sorting mechanism cooperates with the stirring roller 15. When the stirring roller 15 rotates, it abuts and squeezes the liquid sorting mechanism, and the liquid substances in the waste to be processed are collected through the water outlet 20.

[0052] The crushing mechanism is fixedly installed inside the sorting body 1 and below the feed inlet 6 to receive the waste to be processed entering through the feed inlet 6, and crush the solid material of the waste to be processed under the pushing action of the rotating and agitating action of the mixing roller 15.

[0053] The solid sorting mechanism is fixedly installed below the crushing mechanism to receive the waste to be processed after being crushed by the crushing mechanism, and to sort the solid materials of different sizes in the waste to be processed.

[0054] In this embodiment: First, the garbage bin is placed on the elevator 5. The sorting operation of the sorting body 1 is started through the operation panel 3. The first motor 4 drives the elevator 5 to operate, transporting the garbage to be processed in the garbage bin to the groove formed by the sorting body 1 and the top frame 2, that is, the upper surface of the top frame 2. The magnetic picking and stirring mechanism above the top frame 2 drives the stirring roller 15 to move longitudinally and rotate simultaneously, thereby three-dimensionally stirring the garbage layer. Due to the hinge between the magnetic picking and stirring mechanism and the electromagnet 19 and the reciprocating drive of the stirring roller 15, the electromagnet 19 is driven to form a magnetic attraction path of "dynamic scanning + vertical oscillation". When the stirring roller 15 rotates, it abuts against the squeezing liquid picking mechanism, squeezing the free liquid in the garbage to the outlet 20 of the water group for liquid sorting and collection. The pre-treated garbage enters the crushing mechanism through the feed inlet 6. Under the pushing action of the stirring roller 15, the crushing wheel group 31 shears and crushes the solid material. The crushed solid garbage falls into the solid sorting mechanism, and is transported and sorted according to the particle size difference.

[0055] Reference Figures 1 to 13 As shown in this embodiment, the magnetic picking and agitation mechanism includes:

[0056] The second motor 10 is fixedly installed on the surface of the sorting body 1 away from the elevator 5. The inner walls of the two sides of the sorting body 1 above the top frame 2 are respectively connected to the threaded rod 11 and the smooth rod 12. The output end of the second motor 10 is fixedly connected to the transmission end of one side of the threaded rod 11. (It is worth noting that the second motor 10 and the threaded rod 11 in this application can be replaced by a hydraulic cylinder or an electric push assembly. Specifically, the hydraulic cylinder can be fixedly installed on the surface of the sorting body 1 away from the elevator 5. The telescopic rod of the hydraulic cylinder slides through the sorting body 1 and is fixedly connected to the sliding sleeve inclined rod 13.) A set of sliding sleeve inclined rods 13 are symmetrically sleeved on the outside of the threaded rod 11 and the smooth rod 12. The stirring roller 15 is driven between the sliding sleeve inclined rods 13. The two sets of stirring sub-rods of the stirring roller 15 are fixedly connected with silicone pads 16.

[0057] A cavity is provided inside the sliding sleeve slant rod 13 near the second motor 10. A drive gear 141 is provided on the other side of the sliding sleeve slant rod 13 that is close to the second motor 10 and away from the stirring roller 15. The drive end of the drive gear 141 and the drive end on one side of the stirring roller 15 are both driven inside the cavity. A belt 142 is driven outside the drive end of the drive gear 141 and the drive end on one side of the stirring roller 15. A toothed plate 14 is fixedly installed on one side of the upper surface of the sorting body 1. The teeth of the drive gear 141 mesh and drive within the toothed plate 14.

[0058] The upper and lower movable frames 17 are connected above the stirring roller 15. The upper and lower movable frames 17 and the drive gear 141 are hinged together by a hinged drive rod 171. The upper surface of the sliding sleeve inclined rod 13 is fixedly connected to the limiting seat 131. The limiting seat 131 has a limiting groove 132 on one side surface. The limiting groove 132 is slidably connected to the limiting slider 172. The lower surface of the upper and lower movable frames 17 is fixedly connected to the cross frame plate 18. The electromagnet 19 is fixedly installed on the lower surface of the cross frame plate 18.

[0059] In this embodiment, the sorting operation of the magnetic sorting and agitation mechanism specifically includes: when the elevator 5 is running, the magnetic sorting and agitation mechanism is located on one side of the liquid sorting mechanism, thereby providing a dumping position for the processed waste. After the elevator 5 has finished dumping the processed waste, the second motor 10 drives the threaded rod 11 to rotate, and drives the sliding sleeve inclined rod 13 to move smoothly back and forth along the smooth rod 12 through the threaded connection. The sliding sleeve inclined rod 13 synchronously drives the upper and lower movable frames 17 and the cross frame plate 18 to move until it moves to the dumping position close to the elevator 5. When the sliding sleeve inclined rod 13 moves, the drive gear 141 inside it meshes with the toothed plate 14 on the sorting body 1. The mixing roller 15 is driven by the belt 142 to rotate in a cyclical manner, so that the silicone pad 16 on the mixing rod penetrates into the waste layer at the dumping position to achieve flexible stirring. This not only avoids the clumping of waste caused by hard contact, but also effectively moves the waste piled up at the dumping position toward the liquid sorting mechanism. While the drive gear 141 rotates, the upper and lower movable frames 17 are pushed and pulled by the hinged drive rod 171, so that the limiting slider 172 slides up and down along the limiting groove 132 of the limiting seat 131, thereby driving the electromagnet 19 under the cross plate 18 to oscillate vertically, enhancing the adsorption capacity of magnetic substances in deep waste.

[0060] The electromagnet 19 moves longitudinally with the sliding sleeve inclined rod 13 to form a "horizontal scanning path," while its reciprocating up-and-down motion forms a "vertical oscillation path." The superposition of these two actions achieves a three-dimensional magnetic coverage of the waste layer. Furthermore, due to the linkage of the hinged drive rod 171, when one set of sub-rods of the stirring roller 15 tumbles the waste layer to the top, the hinged drive rod 171 will simultaneously drive the electromagnet to move downward, thereby shortening the distance to the waste layer. Combined with the tumbling action of the silicone soft pad 16, this further improves the efficiency of magnetic sorting, increases the probability of magnetic material exposure, and solves the contact blind zone problem of traditional static magnetic attraction.

[0061] It is worth noting that the silicone pad 16 reduces interference from non-magnetic impurities, while the symmetrical distribution structure of the threaded rod 11 and the smooth rod 12 ensures that the sliding sleeve inclined rod 13 does not shift or move, and improves the uniformity of contact between the electromagnet 19 and the waste layer.

[0062] Furthermore, a second hydraulic cylinder 39 is fixedly installed on the side surface of the sorting body 1 near the toothed plate 14. The output end of the second hydraulic cylinder 39 extends into the interior of the sorting body 1, and a pusher frame 40 is fixedly connected to the output end of the second hydraulic cylinder 39.

[0063] A pusher slot 41 is provided on the other side surface of the sorting body 1, which is symmetrical to the pusher frame 40. A third hydraulic cylinder 42 is fixedly installed in the internal cavity of the sorting body 1 near the light rod 12. A pusher plate 43 is fixedly connected to the output end of the third hydraulic cylinder 42. The pusher plate 43 is slidably attached to the inner wall of one side of the pusher slot 41.

[0064] It should be noted that after all the garbage sorting operations are completed, the second motor 10 drives the sliding sleeve inclined rod 13 and the cross frame plate 18 to move to one side of the elevator 5. At this time, the electromagnet 19 is de-energized, and the second hydraulic cylinder 39 and the third hydraulic cylinder 42 are started at the same time. The magnetic material adsorbed on the electromagnet 19 falls to the upper surface between the pusher frame 40 and the pusher slot 41 of the top frame 2. The output end of the second hydraulic cylinder 39 pushes the pusher frame 40, and the pusher frame 40 pushes the fallen magnetic material to move towards the pusher slot 41. The output end of the third hydraulic cylinder 42 drives the pusher plate 43 away from the pusher slot 41, thereby providing an outlet for the magnetic material and realizing the automatic discharge of the magnetic material.

[0065] Reference Figures 1 to 10 As shown in this embodiment, the liquid sorting mechanism includes:

[0066] The extrusion plate 22 is located above the water outlet 20. A water-spreading platform 21 is fixedly installed on the upper surface of the top frame 2 near the water outlet 20. Several sets of sliding grooves 23 are opened on the upper surface of the water-spreading platform 21, which penetrate into the sorting body 1. Slide plates 24 are slidably installed in the sliding grooves 23. The slide plates 24 are fixedly connected to the lower surface of the extrusion plate 22. Several sets of springs 25 are welded between the extrusion plate 22 and the inner wall of the sorting body 1 on the side of the sliding groove 23. The arc surface of the silicone pad 16 abuts and presses against the surface of the extrusion plate 22 away from the springs 25.

[0067] The top frame 2 is fixedly installed with a transfer cavity 26 on the lower surface of the water outlet 20. The bottom wall of the center of the transfer cavity 26 is fixedly connected with a water outlet pipe 27. The sorting body 1 is fixedly installed with a water collection tank 28 inside the water outlet pipe 27.

[0068] In this embodiment, the sorting operation of the liquid sorting mechanism specifically includes: when the stirring roller 15 rotates, the arc surface of the silicone pad 16 periodically abuts against the extrusion plate 22, pushing the extrusion plate 22 to slide inward along the slide groove 23, and the compression spring 25 generates the extrusion force. The extrusion of the extrusion plate 22 and the silicone pad 16 further extrudes the waste layer, so that the free liquid in the waste layer is extruded and guided by the water-spraying platform 21, discharged to the outlet 20 of the water group, and after being buffered by the transfer cavity 26, it is discharged into the water collection tank 28 through the water outlet pipe 27.

[0069] After the stirring roller 15 rotates away, the spring 25 resets and drives the extrusion plate 22 to move back, forming a "extrusion-reset" cycle to continuously separate the liquid.

[0070] Among them, the inclined flow guiding structure of the water-spraying platform 21 avoids liquid residue, and the sliding cooperation between the chute 23 and the slide plate 24 prevents garbage from getting stuck.

[0071] Reference Figures 1 to 14 As shown in this embodiment, the crushing mechanism includes:

[0072] The main crushing housing 30 is fixedly installed on the lower surface of the top frame 2 around the feed inlet 6. The crushing wheel assembly 31 is installed inside the main crushing housing 30. A fourth motor 29 is fixedly installed on one side of the main crushing housing 30. The output end of the fourth motor 29 is fixedly connected to the transmission end of one of the crushing wheels in the crushing wheel assembly 31. The other transmission end of the crushing wheel assembly 31 is fixedly connected to a gear set 32 ​​that meshes with each other.

[0073] The upper and lower surfaces of the main crushing housing 30 are interconnected through grooves, and a feeding hood 33 is fixedly connected to the lower surface of the main crushing housing 30.

[0074] In this embodiment, the sorting operation of the crushing mechanism specifically includes: the fourth motor 29 drives the crushing wheel group 31 to rotate synchronously in the opposite direction through the gear group 32, and shears and crushes the waste to be processed falling from the feed port 6. The crushed solids fall through the through groove that connects the upper and lower parts of the crushing main shell 30, and are directionally introduced into the solid sorting mechanism through the feeding cover 33.

[0075] Among them, the gear set 32 ​​ensures that the two crushing wheels rotate synchronously in opposite directions and the shearing force is uniform, while the direct connection design of the feeding hood 33 avoids the exposure of the crushed material, reducing dust diffusion and odor leakage.

[0076] Reference Figures 1 to 14 As shown in this embodiment, the fixed sorting mechanism includes:

[0077] An inclined cylindrical body 35 and a discharge cover 33 are fixedly covered on the outer surface of the inclined cylindrical body 35, and a slot connected to the discharge cover 33 is opened on the upper surface of the inclined cylindrical body 35 inside the discharge cover 33.

[0078] A fifth motor 34 is fixedly installed on the side of the inclined cylinder 35 near the fourth motor 29. The fifth motor 34 is also fixedly installed inside the sorting body 1. The output end of the fifth motor 34 is fixedly connected to a spiral feeding component 36. The spiral feeding component 36 is rotated inside the inclined cylinder 35. The lower surfaces of the two ends of the inclined cylinder 35 are connected to the first sorting pipe 37 and the second sorting pipe 38 respectively.

[0079] In this embodiment, the sorting operation of the solid sorting mechanism specifically includes: the fifth motor 34 drives the spiral feeder 36 to rotate inside the inclined cylinder 35, conveying the crushed waste along the inclined direction. During the process, the particle size is separated by screening. Small-diameter solids are discharged through the first sorting pipe 37 at the beginning of the conveying, while large-diameter solids are spirally pushed by the spiral feeder 36 to the end and discharged through the second sorting pipe 38.

[0080] The seamless connection between the feeding hood 33 and the inclined cylinder 35 achieves integrated crushing and grading, reducing intermediate transfer links.

[0081] In addition, refer to Figures 1 to 4 As shown in this embodiment: a first hydraulic cylinder 7 is also fixedly installed inside the sorting body 1. A feed baffle 8 is fixedly connected to the output end of the first hydraulic cylinder 7. The feed baffle 8 is slidably disposed on the lower surface of the feed inlet 6. A scraper 9 is fixedly connected to the inner wall of the feed inlet 6 near the first hydraulic cylinder 7. The scraper 9 is obliquely abutting against the upper surface of the feed baffle 8.

[0082] In this embodiment: the first hydraulic cylinder 7 drives the feed baffle 8 to slide along the lower surface of the feed inlet 6. The falling speed of the garbage is adjusted by controlling the opening and closing degree of the baffle. The scraper 9 obliquely abuts against the upper surface of the feed baffle 8 and scrapes off the attached garbage during the sliding process of the feed baffle 8 to avoid residual accumulation.

[0083] Among them, the first hydraulic cylinder 7 is adapted to the feeding requirements of garbage with different moisture content, preventing the feed inlet 6 from being blocked, while the automatic cleaning design of the scraper 9 reduces the frequency of manual cleaning.

[0084] It should be noted that any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should also be within the scope of protection of this invention.
