Description

Technical Field

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

[0002] Waste sorting refers to the classification and sorting of household waste, separating recyclables, hazardous waste, kitchen waste, etc. Waste sorting typically includes devices such as air separators, particle separators, and magnetic separators. Based on the principles that waste has different specific gravities, different falling points, and different particle sizes and compositions after crushing, municipal household waste can be sorted into: ferromagnetic materials (including batteries), organic matter, non-recyclable combustibles, and film plastics, etc. Magnetic separators are typically installed after crushing devices and are mainly used to recycle small iron items such as wires and nails. For example, Chinese patent document CN202411121675.1 discloses a construction waste sorting and crushing device, including: a processing box; a discharge port on the side of the processing box; an electromagnet consisting of a conductor arc plate and an insulator arc plate; a second external connector fixed to the rear end of the separating shaft; and the outer ends of the electromagnet plate connected to the conductor arc plate and the second external connector via circuits. The electromagnet plate adsorbs iron items such as wires in the construction waste, and the remaining waste automatically falls to the bottom of the processing box. The device can also automatically and in linkage use a scraper to remove iron filings and iron items that have not detached from the surface of the electromagnet plate, thus achieving the recycling of iron items in the waste. However, in the above patent, the waste falls due to gravity, resulting in a very fast falling speed. Furthermore, the adsorption range of the electromagnet plate is limited, and the rapidly falling waste affects the adsorption effect. Iron items adsorbed onto the electromagnet plate further reduce its adsorption capacity.

[0003] Therefore, it is necessary for those skilled in the art to provide a waste sorting and quantitative recycling device to recover iron products from waste and improve recycling efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a quantitative recycling device for waste sorting, in order to solve the technical problem that the magnetic separation device in the existing waste sorting process has an effective adsorption range but low adsorption capacity.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a waste sorting and quantitative recycling device, including a shell and a conveyor belt movably disposed in the shell. The conveyor belt carries the waste and moves it horizontally. The shell is provided with multiple magnetic attraction devices, which are electromagnets. The magnetic attraction devices are movably disposed in the shell and can attract iron products in the waste. The shell is provided with a receiving groove, and a weighing device is provided outside the shell. Part of the magnetic attraction device can abut against the side wall of the receiving groove, and both ends of the magnetic attraction device can be placed on the weighing pan of the weighing device.

[0006] Furthermore, a magnetic cavity is formed inside the housing, and a groove is provided on the wall of the housing, which penetrates two opposite side walls of the housing. The magnetic device includes a magnetic part and a mating part. The two ends of the magnetic part are rotatably disposed in the mating part. A magnet is provided inside the magnetic part. The magnetic part is located inside the magnetic cavity, and the mating part is slidably disposed in the groove.

[0007] Furthermore, the slide includes a vertical groove and a horizontal groove, the mating part is connected to the vertical groove, and the mating part is separated from the horizontal groove; the receiving groove is located in the magnetic cavity and on one side of the vertical groove, the receiving groove is a square groove with an open top surface, and the upper opening surface of the receiving groove faces the horizontal groove.

[0008] Furthermore, the end of the receiving groove is provided with a blocking part in the horizontal groove. The blocking part opens downward from the upper opening of the receiving groove and penetrates the wall of the housing. The blocking part is composed of multiple arc-shaped grooves, and the diameter of the arc-shaped grooves on the blocking part is the same as the diameter of the magnetic attraction part.

[0009] Furthermore, the magnetic attraction device is provided with a support part that extends to the outside of the housing, and the weighing device is provided with a support device. One end of the support device abuts against the outer circumferential surface of the support part, and the other end of the support device abuts against the weighing pan of the weighing device. The support device is a telescopic rod.

[0010] Furthermore, the weighing device is an electronic scale.

[0011] Furthermore, the slide groove has a dovetail groove on the side wall of the vertical groove, and the mating part has a dovetail tenon on the surface facing the slide groove. The dovetail tenon is mated and connected in the dovetail groove. The horizontal groove has an opening that connects to the dovetail groove on the side wall of the vertical groove. The outline of the opening is larger than the outline of the dovetail tenon on the mating part.

[0012] Furthermore, the axis of the magnetic suction part on the magnetic suction device is arranged parallel to the upper plane of the conveyor belt, and there is a gap between the outer circumferential side of the magnetic suction part and the conveyor belt. The axis of one magnetic suction device is higher than the axis of the other magnetic suction device.

[0013] The beneficial effects of this invention are as follows: This invention employs a horizontal conveying method for waste sorting, with controllable conveying speed, effectively ensuring stable recycling. Simultaneously, when the conveyor belt moves at a high speed, the height of the magnetic suction device can be adjusted by changing its position within the chute, ensuring the magnetic suction part can pass through the waste, resulting in better adsorption effect and adsorption area, thus guaranteeing a higher recycling rate. Furthermore, this invention utilizes a weighing device to dynamically monitor the weight of the magnetic suction device in real time. When the weight of the magnetic suction device reaches a threshold, it is manually replaced, thereby achieving quantitative recycling, ensuring the adsorption effect of the magnetic suction device, and improving the stability of iron product recycling. Because multiple magnetic suction devices are installed, and each magnetic suction device can be replaced individually, non-stop replacement is possible, greatly improving processing efficiency.

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] Please see Figure 1This utility model provides a waste sorting and quantitative recycling device, including a housing 10 and a conveyor belt 20 movably disposed within the housing 10. A drive motor (not shown in the figure) is installed on the conveyor belt 20. The drive motor drives the conveyor belt 20 to rotate. The crushed waste is placed on the conveyor belt 20, and the conveyor belt 20 carries the waste through the housing 10. The conveyor belt 20 is a common rubber conveyor belt on the market, and its specific structure will not be described in detail here.

[0022] Further, please refer to Figure 2 , Figure 4 The housing 10 has a hollow square shell structure with a magnetic suction cavity 11 inside. A first opening 12 and a second opening 13 are respectively opened on opposite sides of the housing 10. The first opening 12 and the second opening 13 penetrate the wall of the housing 10 and connect to the magnetic suction cavity 11. Part of the conveyor belt 20 passes through the first opening 12 and the second opening 13, thereby realizing the conveying of garbage into the magnetic suction cavity 11.

[0023] In use, the first opening 12 can spread the piled-up garbage on the conveyor belt 20 before it enters the magnetic suction cavity 11, ensuring that the iron products inside can be adsorbed and improving the recycling efficiency.

[0024] Further, please refer to Figure 3 , Figure 5 A groove 14 is formed on the wall of the housing 10 between the first opening 12 and the second opening 13. The groove 14 penetrates two opposite side walls of the housing 10 and is symmetrically arranged on both sides of the conveyor belt 20. A magnetic suction device 15 is slidably installed inside the groove 14. The magnetic suction device 15 is elongated and its two ends are connected to the groove 14. The magnetic suction device 15 is located above the conveyor belt 20. In use, the conveyor belt 20 carries the waste into the magnetic suction cavity 11. The waste passes through the magnetic suction device 15, and the magnetic force of the magnetic suction device 15 attracts iron products in the waste, thus achieving recycling.

[0025] Specifically, the magnetic suction device 15 is provided in multiple parts, each including a magnetic suction part 151 and a mating part 152. The magnetic suction part 151 is cylindrical, and its two ends are rotatably mounted in the mating part 152 using bearings. The axis of the magnetic suction part 151 is parallel to the upper plane of the conveyor belt 20. A gap is left between the outer circumferential side of the magnetic suction part 151 and the conveyor belt 20 to ensure that the waste can pass smoothly. The mating part 152 is rectangular and is fitted into the chute 14. The mating part 152 can slide along the opening direction of the chute 14. In use, when the waste passes through the magnetic suction part 151, the iron objects inside the waste are attracted to the magnetic suction part 151. The rotatable magnetic suction part 151 ensures that the iron objects are evenly distributed on the circumferential side of the magnetic suction part 151, guaranteeing the amount of attraction and improving the usage effect.

[0026] In this embodiment, the magnetic attraction part 151 is an electromagnet, which generates a magnetic field by energizing it, thereby achieving the attraction of iron products. The iron products automatically fall off after the power is turned off.

[0027] In this embodiment, a rotary motor (not shown) is provided inside the mating part 152, and the magnetic suction part 151 is fixedly connected to the output shaft of the rotary motor to ensure the stability of the rotation of the magnetic suction part 151, realize the adsorption of iron products, and improve the adsorption amount and uniformity.

[0028] In this embodiment, a limiting plate (not shown) is also provided inside the magnetic suction cavity 11. The limiting plate is located on one side of the magnetic suction part 151, and the lower plane of the limiting plate is flush with the lowest point of the circumferential surface of the magnetic suction part 151. The limiting plate flattens the passing garbage, thereby ensuring that the magnetic suction part 151 can attract the iron products inside, while preventing the garbage from scraping away the iron products attracted to the magnetic suction part 151, thus improving the stability of use. One limiting plate is provided on one side of each magnetic suction part 151. By limiting the height of different limiting plates, they are distributed in a stepped manner, thereby continuously reducing the height of the garbage, ensuring that the iron products inside are fully absorbed, and improving the use effect.

[0029] In other embodiments, the height of the first opening 12 is flush with the lowest point of the circumferential surface of the magnetic suction part 151, so that the garbage entering the magnetic suction cavity 11 is spread flat on the conveyor belt 20, thereby ensuring that the magnetic suction part 151 can attract the internal iron products, while preventing the garbage from scraping away the iron products attracted to the magnetic suction part 151, thus improving the stability of use.

[0030] Furthermore, the chute 14 has an inverted U-shaped structure and includes a vertical chute 141 and a horizontal chute 142. The vertical chute 141 is vertically arranged relative to the upper plane of the conveyor belt 20, and the horizontal chute 142 is horizontally arranged relative to the upper plane of the conveyor belt 20. The horizontal chute 142 is located above the vertical chute 141 and communicates with it. There are two vertical chute 141s arranged symmetrically. The bottom of the vertical chute 141 is higher than the upper plane of the conveyor belt 20 to ensure that after the magnetic suction device 15 is installed, its magnetic suction part 151 is also higher than the upper plane of the conveyor belt 20, so that the garbage can pass smoothly through the magnetic suction part 151. At the same time, if the garbage is piled up, the rotatable magnetic suction part 151 can spread the garbage evenly on the conveyor belt 20, thereby increasing the adsorption area of ​​the magnetic suction part 151 and ensuring adsorption efficiency.

[0031] In this embodiment, the axial height of the magnetic suction part 151 near the first opening 12 is higher than that of the magnetic suction part 151 near the second opening 12. This allows for the adsorption of waste at different heights, ensuring effective adsorption while preventing a large number of iron items from being completely adsorbed by the same magnetic suction device 15, thus ensuring the overall stability of the invention. This invention uses a horizontal waste conveying method for sorting, with controllable waste transport speed, effectively ensuring stable recycling. Furthermore, when the conveyor belt 20 moves at a high speed, the height of the magnetic suction device 15 can be adjusted by regulating its position within the chute 14, ensuring that the magnetic suction part 151 can pass through the waste, resulting in better adsorption and a higher recycling rate.

[0032] Furthermore, the housing 10 also includes a receiving groove 16 located within the magnetic suction cavity 11, between two vertical grooves 141. The receiving groove 16 is a square groove with an open top surface, its upper opening facing the horizontal groove 142. A blocking part 17 is located at the end of the receiving groove 16 within the horizontal groove 142, extending downwards from the upper opening and penetrating the wall of the housing 10. The blocking part 17 is composed of multiple arc-shaped grooves, the diameter of which is the same as the diameter of the magnetic suction part 151. In use, the magnetic suction part 151 is placed within the blocking part 17, and the power supply to the magnetic suction part 151 is disconnected, causing it to lose its magnetic field. This allows the iron product to detach and slide into the receiving groove 16, thus achieving the recycling of the iron product.

[0033] This invention places the receiving tank 16 for recycling iron products on one side of the magnetic suction device 15, thereby reducing the handling by operators and reducing labor intensity. At the same time, the magnetic suction device 15 only moves inside the housing 10, effectively preventing iron products from falling outside the housing 10, thereby reducing the loss of iron products and improving recycling efficiency.

[0034] In this embodiment, a dovetail groove is provided on the side wall of the vertical groove 141 on the slide 14, and a dovetail tenon is provided on the surface of the mating part 152 facing the slide 14. The dovetail tenon is engaged and connected in the dovetail groove, thereby ensuring that the mating part 152 can slide stably along a fixed track in the vertical groove 141. The mating part 152 is movably disposed in the horizontal groove 142. When the mating part 152 moves from the vertical groove 141 to the horizontal groove 142, the mating part 152 separates from the side wall of the horizontal groove 142, thereby allowing the mating part 152 to move freely in the horizontal groove 142. The operator holds the mating part 152 on the magnetic suction device 15, abuts the magnetic suction part 151 on the magnetic suction device 15 against the blocking part 17, and disconnects the power supply of the magnetic suction device 15, so that the iron product on the magnetic suction part 151 can be detached, completing the recycling of the iron product.

[0035] Understandably, the horizontal groove 142 is provided with an opening (not shown in the figure), which connects to the dovetail groove on the side wall of the vertical groove 141. The outline of the opening is larger than the outline of the dovetail tenon on the mating part 152, so that the mating part 152 can be separated after sliding from the vertical groove 141 to the horizontal groove 142, ensuring the stability of use.

[0036] In other embodiments, the mating part 152 of the magnetic attraction device 15 is detachably connected to the vertical groove 141 of the slide 14 using fasteners such as bolts or screws, and the mating part 152 is separately disposed from the horizontal groove 142.

[0037] In other embodiments, a cylinder is provided below the mating part 152 inside the housing 10. The telescopic rod of the cylinder abuts against the mating part 152 to push the mating part 152 from the vertical groove 141 into the horizontal groove 142, thereby reducing manual handling, lowering labor intensity, and improving the stability of use.

[0038] Furthermore, a support portion 153 is provided on the side of the magnetic attraction device 15 located away from the magnetic attraction portion 151 on the mating portion 152. The support portion 153 extends outward from the slide groove 14 to the outside of the housing 10. A weighing device 18 is also provided outside the housing 10. A support device 19 is provided on the weighing device 18. One end of the support device 19 abuts against the outer circumferential surface of the support portion 153, and the other end of the support device 19 abuts against the weighing pan of the weighing device 18.

[0039] In this embodiment, the weighing device 18 is a commercially available electronic scale, which includes a weighing pan and a weighing body. The weighing pan is used to support the item to be measured, while the weighing body provides a stable support structure. It can be purchased directly, and the specific structure of the weighing device 18 will not be described in detail here.

[0040] This invention utilizes a weighing device 18 to dynamically monitor the weight of the magnetic suction device 15 in real time. When the weight of the magnetic suction device 15 reaches or exceeds a threshold, it is manually replaced, thereby achieving quantitative recycling within a certain range and ensuring the adsorption effect of the magnetic suction device 15. Since the adsorption process of the magnetic suction device 15 is complex and its weight is prone to fluctuation, this invention directly replaces the magnetic suction device 15 after it has adsorbed a certain weight, preventing excessive adsorption from reducing its adsorption capacity and preventing excessive weight from making replacement difficult. This ensures the adsorption effect and improves the stability of iron product recycling. Furthermore, since this invention can set up multiple magnetic suction devices 15, and each magnetic suction device 15 can be replaced individually, it can achieve replacement without stopping the machine, greatly improving processing efficiency.

[0041] The support device 19 includes, but is not limited to, a telescopic rod, which provides support for the magnetic attraction device 15 while adjusting the height of the magnetic attraction device 15 to ensure the stability of the support.

[0042] The specific operation method of this utility model is as follows: Step 1: Pour the garbage onto the upper surface of the conveyor belt 20. The conveyor belt 20 drives the garbage into the magnetic suction cavity 11 of the housing 10 to complete the loading.

[0043] Step 2: The waste comes into contact with the magnetic part 151 of a magnetic suction device 15 or passes through the magnetic part 151. The rotatable magnetic part 151 spreads the waste flat on the conveyor belt 20 and attracts the iron products in the waste, completing the first attraction.

[0044] Step 3: The waste comes into contact with another magnetic attraction device 15, which further attracts and flattens the waste, completing the second attraction.

[0045] Step 4: The waste is discharged from the second opening 13, completing the sorting process.

[0046] Step 5: When the weighing device 18 reaches the threshold, manually slide a magnetic suction device 15. The mating part 152 of the magnetic suction device 15 slides along a fixed track in the vertical groove 141. When the mating part 152 moves from the vertical groove 141 to the horizontal groove 142, the mating part 152 separates from the side wall of the horizontal groove 142. The operator holds the mating part 152 on the magnetic suction device 15 and abuts the magnetic suction part 151 on the magnetic suction device 15 against the blocking part 17, disconnects the power supply of the magnetic suction device 15, and removes the iron products on the magnetic suction part 151, thus completing the quantitative recycling of the iron products.

[0047] This invention employs a horizontal waste sorting method, with controllable waste transport speed, effectively ensuring stable recycling. Simultaneously, when the conveyor belt 20 moves at a high speed, the height of the magnetic suction device 15 can be adjusted by regulating its position within the chute 14, ensuring that the magnetic suction part 151 can pass through the waste, resulting in better adsorption effect and adsorption area, thus guaranteeing a high recycling rate. Furthermore, this invention utilizes a weighing device 18 to dynamically monitor the weight of the magnetic suction device 15 in real time. When the weight of the magnetic suction device 15 reaches or exceeds a threshold, it is manually replaced, thereby achieving quantitative recycling within a certain range, ensuring the adsorption effect of the magnetic suction device 15, and improving the stability of iron product recycling. Because multiple magnetic suction devices 15 are installed, and each magnetic suction device 15 can be replaced individually, non-stop replacement is possible, greatly improving processing efficiency.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
