Description

Technical Field

[0001] This utility model relates to the field of solid waste recycling technology, and in particular to a solid waste treatment and recycling device. Background Technology

[0002] Solid waste refers to solid and semi-solid waste materials generated by humans in production, construction, daily life, and other activities that cannot be utilized at a certain time and place and are discarded, thus polluting the environment. Currently, in order to facilitate the recycling and utilization of solid waste, it is necessary to crush it.

[0003] A search revealed a solid waste treatment and recycling device with authorization announcement number CN219273925U. Addressing the problem that existing technologies suffer from wear and tear on the grid plate due to the varying sizes and angularity of solid waste during actual use, which can damage the grid plate and affect its vibration-induced separation of solid waste and overall work efficiency, the following solution is proposed: The device includes a housing and a grid plate. Inclined plates are symmetrically fixedly connected to the inner wall of the housing. The grid plate is movably connected to the inner wall of the housing. Insert blocks are fixedly connected to both the front and rear sides of the grid plate. Fixed boxes are symmetrically fixedly connected to the inner wall of the housing.

[0004] However, the solid waste treatment and recycling device mentioned above still has shortcomings in use. Because the stone particles produced during the crushing of construction waste vary in size, and different types of stone are used in different scenarios, the crushed stone needs to be screened in multiple stages after crushing. The above-mentioned device can only perform single-stage screening of the crushed solid waste and cannot perform multi-stage fine screening. At the same time, it is inconvenient to screen out and recycle metallic magnetic objects in construction waste, thereby avoiding the waste of metallic magnetic objects. Therefore, we propose a solid waste treatment and recycling device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings mentioned above by proposing a solid waste treatment and recycling device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A solid waste treatment and recycling device includes a box for treating and recycling solid waste. A feeding hopper is fixedly connected to the top of the box. A crushing mechanism for crushing solid waste is provided between the box and the feeding hopper. A magnetic debris screening mechanism is provided inside the box. Two screen plates are rotatably connected to the inner walls of the front and rear sides of the box. Screens are fixedly connected to the screen plates. The upper screen has a larger aperture than the lower screen. A high-efficiency multi-stage screening mechanism is provided between the two screen plates, the box, and the feeding hopper. Guide plates are fixedly connected to the inner walls of both sides of the box.

[0008] As a preferred embodiment of the present invention, the crushing mechanism includes a drive motor fixedly connected to the top of the housing, and a rotating shaft rotatably connected to the inner walls on both sides of the feed hopper. The output shaft of the drive motor is fixedly connected to one end of the rotating shaft, and a plurality of crushing blades are fixedly connected to the outer side of the rotating shaft.

[0009] As a preferred embodiment of this utility model, a bearing seat is fixedly connected to the top of the housing, a bearing is fixedly sleeved inside the bearing seat, and the rotating shaft is fixedly sleeved inside the inner ring of the bearing.

[0010] In a preferred embodiment of this invention, two openings are provided on one side of the housing. The high-efficiency multi-stage screening mechanism includes a worm gear rotatably connected to one side of the housing, and a worm fixedly connected to the end of the rotating shaft away from the drive motor. The worm meshes with the worm gear. A drive column is fixedly connected to the front side of the worm gear. A moving rod is movably abutted against the outer side of the drive column. The bottom end of the moving rod is fixedly connected to the top of the upper screen plate. The two screen plates are rotatably connected to the same connecting rod. A return spring is fixedly connected to the top inner wall of the opening. The bottom end of the return spring is fixedly connected to the top of the corresponding screen plate.

[0011] As a preferred embodiment of this utility model, a baffle is fixedly connected to one inner wall of the box body, and the baffle corresponds to the opening.

[0012] As a preferred embodiment of this utility model, the magnetic debris screening mechanism includes a mounting frame that is slidably fitted inside the box. Slider blocks are fixedly connected to both sides of the mounting frame. Sliding grooves are provided on the inner walls of both sides of the box. The two sliders are slidably fitted into the corresponding sliding grooves. Electromagnetic rods for adsorbing magnetic debris are fixedly connected to the inner walls of the front and rear sides of the mounting frame.

[0013] As a preferred embodiment of this utility model, a screw is threadedly connected to the other side of the housing, and the slider on the right side is fixedly connected to the right side groove by the screw.

[0014] As a preferred embodiment of this utility model, two discharge ports are provided on the other side of the box body, the discharge ports are corresponding to the screen plate, and a collection box is slidably sleeved inside the box body.

[0015] In this utility model, a solid waste treatment and recycling device is described. The crushed solid waste falls along the guide plate into the gap between the electromagnetic rods in the installation frame. The electromagnetic rods are energized and then magnetized, which attracts magnetic impurities in the solid waste onto the electromagnetic rods. After screening is completed, the screws are loosened so that they do not fix the slider to the installation frame. The installation frame is pulled out and the electromagnetic rods are de-energized, causing the electromagnetic rods to lose their magnetism. At this time, the magnetic impurities fall down for recycling and reuse.

[0016] In this utility model, a solid waste treatment and recycling device is described. The crushed solid waste falls onto an upper screen plate and is screened by two screens with different apertures. The largest particles are discharged from the upper outlet, the intermediate particles are discharged from the lower outlet, and the smallest particles fall into a collection box for collection. This allows for multi-stage screening, separating solid waste of different sizes in one pass, thus improving screening efficiency. Furthermore, the rotating shaft drives the rotation of a worm gear. The worm gear rotates, which in turn drives the drive column to rotate. The drive column then causes the moving rod and the upper screen plate to deflect. Through the transmission of the connecting rod, the upper screen plate causes the lower screen plate to deflect upwards, compressing the return spring. When the drive column is no longer in contact with the moving rod, the screen plate will deflect downwards and return to its original position under the force of the return spring. This drives the two screen plates to deflect up and down repeatedly, which not only improves the screening efficiency but also facilitates the discharge of solid waste particles and prevents impurities from getting on the screen.

[0017] This utility model features a reasonable structural design and a highly efficient multi-stage screening mechanism. It can not only perform multi-stage screening of crushed solid waste, separating solid waste particles of different sizes in one go and improving screening efficiency, but also has a screen plate that can deflect up and down to further improve screening efficiency. It also facilitates the discharge of solid waste particles and can screen out and recycle magnetic impurities in solid waste particles, avoiding the waste of metallic magnetic objects.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4 A solid waste treatment and recycling device includes a box 1 for treating and recycling solid waste. A feed hopper 2 is fixedly connected to the top of the box 1. A crushing mechanism 3 for crushing solid waste is provided between the box 1 and the feed hopper 2. A magnetic debris screening mechanism 4 is provided inside the box 1. Two screen plates 510 are rotatably connected to the inner walls of the front and rear sides of the box 1. A screen 509 is fixedly connected to the screen plate 510. The aperture of the upper screen 509 is larger than that of the lower screen 509. A high-efficiency multi-stage screening mechanism 5 is provided between the two screen plates 510, the box 1 and the feed hopper 2. Guide plates 7 are fixedly connected to the inner walls of both sides of the box 1.

[0025] Furthermore, refer to Figure 1-3 As shown, the crushing mechanism 3 includes a drive motor 32 fixedly connected to the top of the housing 1, and a rotating shaft 33 rotatably connected to the inner walls on both sides of the feed hopper 2. The output shaft of the drive motor 32 is fixedly connected to one end of the rotating shaft 33, and a number of crushing blades 34 are fixedly connected to the outer side of the rotating shaft 33.

[0026] The above method involves placing the solid waste to be treated and recycled into the feed hopper 2, and driving the rotating shaft 33 and the crushing blade 34 to rotate via the drive motor 32, thereby crushing the solid waste.

[0027] Furthermore, a bearing seat 31 is fixedly connected to the top of the housing 1, and a bearing is fixedly sleeved inside the bearing seat 31. The rotating shaft 33 is fixedly sleeved inside the inner ring of the bearing, which helps to support the rotating shaft 33 and make its rotation more stable.

[0028] Furthermore, refer to Figure 1-3As shown, two openings 506 are provided on one side of the housing 1. The high-efficiency multi-stage screening mechanism 5 includes a worm gear 502 rotatably connected to one side of the housing 1, and a worm 501 fixedly connected to the end of the rotating shaft 33 away from the drive motor 32. The worm 501 meshes with the worm gear 502. A drive column 503 is fixedly connected to the front side of the worm gear 502. A moving rod 504 is movably abutted against the outer side of the drive column 503. The bottom end of the moving rod 504 is fixedly connected to the top of the screen plate 510 above. The same connecting rod 508 is rotatably connected between the two screen plates 510. A return spring 507 is fixedly connected to the top inner wall of the opening 506. The bottom end of the return spring 507 is fixedly connected to the top of the corresponding screen plate 510.

[0029] Using the above scheme: After screening by two screens 509 with different apertures, the largest particles are discharged from the upper outlet 8, the intermediate particles (crushed solid waste) are discharged from the lower outlet 8, and the smallest particles (crushed solid waste) fall into the collection box 6 for collection. This allows for multi-stage screening, separating solid waste of different sizes in one pass, improving screening efficiency. Furthermore, the rotating shaft 33 drives the worm gear 501 to rotate, which in turn drives the worm wheel 502 to rotate, which in turn drives the drive column 503 to rotate. 03 drives the moving rod 504 to deflect the upper screen plate 510. Through the transmission of the connecting rod 508, the upper screen plate 510 drives the lower screen plate 510 to deflect upward and squeeze the return spring 507. When the driving rod 503 is not in contact with the moving rod 504, the screen plate 510 will deflect downward and return to its original position under the elastic force of the return spring 507. This drives the two screen plates 510 to deflect up and down, which not only improves the screening efficiency, but also facilitates the discharge of solid waste particles and avoids the occurrence of impurities on the screen 509.

[0030] Furthermore, a baffle 505 is fixedly connected to one inner wall of the box 1. The baffle 505 corresponds to the opening 506. The baffle 505 blocks the solid waste from being discharged from the opening 506.

[0031] Furthermore, refer to Figure 1-4 As shown, the magnetic impurity screening mechanism 4 includes a mounting frame 41 that is slidably fitted inside the housing 1. Slider 43 is fixedly connected to both sides of the mounting frame 41. Slide grooves 42 are provided on the inner walls of both sides of the housing 1. The two sliders 43 are slidably fitted into the corresponding slide grooves 42. Electromagnetic rods 45 for adsorbing magnetic impurities are fixedly connected to the inner walls of the front and rear sides of the mounting frame 41. Screws 44 are threadedly connected to the other side of the housing 1. The slider 43 on the right side is fixedly connected to the slide groove 42 on the right side by the screws 44.

[0032] Using the above scheme: The crushed solid waste falls along the guide plate 7 into the gap between the electromagnetic rods 45 in the mounting frame 41. Through the magnetism of the electromagnetic rods 45 after being energized, magnetic impurities in the solid waste can be attracted to the electromagnetic rods 45. After screening is completed, the screws 44 are loosened so that the screws 44 do not fix the slider 43 to the mounting frame 41. The mounting frame 41 is pulled out, and the electromagnetic rods 45 (a rechargeable energy storage device can be set on the mounting frame 41 to supply power to the electromagnetic rods 45) are de-energized, so that the electromagnetic rods 45 lose their magnetism. At this time, the magnetic impurities fall down for recycling and reuse.

[0033] Furthermore, two discharge ports 8 are provided on the other side of the box body 1. The discharge ports 8 correspond to the screen plate 510. A collection box 6 is slidably fitted inside the box body 1 to facilitate the discharge and collection of solid waste particles of different sizes.

[0034] In this invention, during use, the solid waste to be treated and recycled is placed into the feed hopper 2. The drive motor 32 drives the rotation of the rotating shaft 33 and the crushing blade 34, thereby crushing the solid waste. The crushed solid waste falls along the guide plate 7 into the gap between the electromagnetic rods 45 in the mounting frame 41. Through the magnetism of the electromagnetic rods 45 after being energized, magnetic impurities in the solid waste can be attracted to the electromagnetic rods 45. The crushed solid waste falls onto the screen plate 510 above. After being screened by two screens 509 with different apertures, the largest particles are discharged from the upper discharge port 8, the middle particles of crushed solid waste are discharged from the lower discharge port 8, and the smallest particles of crushed solid waste fall into the collection box 6 for collection. This allows for multi-stage screening and can separate different sizes of solid waste at once. The granular solid waste is screened out, improving screening efficiency. The rotating shaft 33 drives the worm 501 to rotate, which in turn drives the worm wheel 502 to rotate. The worm wheel 502 drives the drive column 503 to rotate, which in turn drives the moving rod 504 to deflect the upper screen plate 510. Through the transmission of the connecting rod 508, the upper screen plate 510 drives the lower screen plate 510 to deflect upward and squeeze the return spring 507. When the drive column 503 is not in contact with the moving rod 504, the screen plate 510 will deflect downward and return to its original position under the elastic force of the return spring 507. This drives the two screen plates 510 to deflect up and down repeatedly, which not only improves screening efficiency but also facilitates the discharge of solid waste particles and avoids the occurrence of impurities on the screen 509.

[0035] After screening is completed, loosen screw 44 so that screw 44 does not fix slider 43 to mounting frame 41, pull out mounting frame 41, and disconnect power to electromagnetic rod 45 (a rechargeable energy storage device can be installed on mounting frame 41 to power electromagnetic rod 45), so that electromagnetic rod 45 loses magnetism. At this time, magnetic debris falls down for recycling and reuse.
