Description

Technical Field

[0001] The present invention relates to the technical field of recycling and treatment, and specifically to a garbage treatment classification and screening device. Background Art

[0002] Garbage is solid waste generated in human daily life and production. Due to the large discharge volume, complex and diverse components, and its polluting, resource-based and social nature, it requires harmless, resource-based, reduction and socialized treatment. If not properly treated, it will pollute the environment, affect environmental hygiene, waste resources, damage the safety of production and life, and disrupt social harmony. Garbage treatment is to quickly remove garbage, carry out harmless treatment, and finally make reasonable use. Its purpose is harmlessness, resource utilization and reduction. Garbage can be classified into domestic garbage, production garbage, construction garbage, etc. according to different sources.

[0003] After the solid waste of domestic garbage is classified, it needs to be compressed and packaged. However, small-volume iron waste is sometimes easily mixed into the solid waste, which is likely to affect the safety of subsequent compression and packaging, and at the same time cause unnecessary waste of iron resources. Due to the complexity and diversity of domestic garbage, the traditional manual sorting method is inefficient, costly, and cannot meet the needs of large-scale treatment. Therefore, a magnetic separation treatment device has emerged. This device uses the magnetic force principle to separate magnetic metals in construction garbage through a strong magnetic field, so as to achieve efficient recycling of resources. This device usually includes important parts such as a feeding system, a magnetic separation system, and a conveying system.

[0004] However, in the actual operation process, when the garbage material is conveyed to the position of the magnetic separation cylinder, due to the relatively concentrated conveying of the material, it is easy to produce accumulation, which affects the adsorption effect of the magnetic separation cylinder on the iron waste, resulting in poor magnetic separation stability and reducing the screening effect of the iron waste in domestic garbage. Summary of the Invention

[0009] Preferably, the side wall of the plate body is fixedly connected with an elastic telescopic rod, the elastic telescopic rod is made of ferromagnetic materials, on the outer side wall of one end of the magnetic separation cylinder facing the side plate is provided a connecting groove.

[0010] Preferably, the side wall of the plate body is fixedly connected with a number of telescopic connecting rods, the other ends of the number of telescopic connecting rods are jointly and fixedly connected with an annular blanking plate, the blanking plate is sleeved outside the magnetic separation cylinder, on the side wall of the box body is provided a notch, inside the notch is provided a baffle plate with a matching shape, and on the opposite sides of the blanking plate and the baffle plate are fixedly provided connecting columns.

[0011] Preferably, the magnetic separation cylinder includes an adsorption section with magnetism and a connecting section without magnetism, and the opening of the connecting section is closed.

[0012] Preferably, on one side of the recycling table is provided an inclined feeding conveyor, on the surface of the conveyor belt of the feeding conveyor is installed a conveying component, the conveying component includes a number of conveying layers, and the conveying layers are arranged around the surface of the conveyor belt of the feeding conveyor.

[0013] Preferably, the conveying layer includes two vertical slide rails and a magnetic plate, the vertical slide rails are fixedly arranged on the conveyor belt surface of the feed conveyor, the vertical slide rails are internally slidably connected with a horizontal slide rail, a sliding plate is arranged on one side of the horizontal slide rail, a sliding groove is opened on the surface of the sliding plate, the sliding groove is slidably connected to one end of the horizontal slide rail, the side wall of the sliding groove is fixedly connected with an elastic member, and the other end of the elastic member is fixedly connected to the horizontal slide rail.

[0014] Preferably, the sliding plate is made of ferromagnetic material, and two magnetic plates are provided and fixedly disposed on the upper walls on both sides of the feed conveyor frame.

[0015] Preferably, the conveying assembly also includes a fixed bracket, one end of which is fixedly connected to the inner wall of the side plate, and a T-shaped scraper is fixedly provided on the upper surface of the fixed bracket, and the top end of the scraper is in contact with the conveyor belt of the feed conveyor.

[0016] Working principle: When in use, the electric push cylinder contracts and closes the screening box, and garbage is quantitatively added to the inside of the screening box through the feed conveyor. The iron waste is collected by the magnetic separation cylinder. At this time, the motor drives the plate body to rotate, and the plate body drives the conveying plate to rotate, driving the garbage to circulate in the screening box so that the garbage can be dispersed to avoid accumulation. It can effectively improve the collection effect of the magnetic separation cylinder on iron waste. After the garbage screening is completed, the electric push cylinder extends and drives the magnetic separation cylinder and the box body to move away from the side plate, so as to achieve the effect of automatically opening the screening box. At this time, the unabsorbed garbage in the screening box is intercepted by the ring body and is subsequently extracted by the box body. When the screening box is opened, the magnetic separation cylinder and the conveying plate are offset and the magnetic attraction disappears. The conveying plate located in the lower area slides downward under the influence of gravity, thereby increasing the spacing between the adjacent conveying plates on the lower side, so that the garbage can fall better, thereby avoiding or reducing the problem of large pieces of garbage being stuck between the conveying plates.

[0017] When the screening box is opened and drives the magnetic separation drum to move, the unloading plate drives the telescopic connecting rod to extend under the push of the impurities adsorbed on the outside of the magnetic separation drum, and when it is extended to the maximum extent, the unloading plate stops moving. Since the unloading plate has passed through the ring body, the iron waste and the screened garbage can fall on both sides of the ring body respectively to avoid re-mixing. At this time, the unloading plate can scrape off the iron waste adsorbed on the surface of the magnetic separation drum when it moves through, so as to achieve the effect of automatically removing the iron waste on the surface of the magnetic separation drum. At the same time, when the box body moves, the baffle plate remains stationary to intercept the fallen iron waste, and after the box body and the baffle plate are staggered, some of the fallen iron waste falls and is discharged.

[0018] When the box body moves and closes against the side plate, it drives the magnetic separation cylinder through the elastic telescopic rod. The magnetic separation cylinder applies a magnetic suction force to the elastic telescopic rod, causing the bottom end of the elastic telescopic rod to slide downward until it abuts against the magnetic separation cylinder. When the subsequent plate rotates, it drives the elastic telescopic rod to rotate. When the elastic telescopic rod rotates and aligns with the connecting groove, the elastic telescopic rod extends again and inserts into the connecting groove. Thus, when the plate rotates, it drives the magnetic separation cylinder to rotate through the elastic telescopic rod. When the magnetic separation cylinder rotates, it can adjust the overall adsorption area, enabling the entire magnetic separation cylinder to fully perform adsorption and utilization. Moreover, the magnetic separation cylinder does not require additional driving equipment, which can reduce costs, realize the multi-functional application of a single motor, and achieve the application of more functions with the least input of structure and equipment.

[0019] The elastic force of the elastic member pushes the sliding plate, causing the two sliding plates to close and push the garbage. When the sliding plate moves to the lower side of the feeding conveyor, due to the action of gravity, the horizontal slide rail slides downward along the vertical slide rail, maintaining a certain gap between the sliding plate and the conveyor belt. At the same time, when the sliding plate moves through the magnetic plate, the magnetic separation suction force of the magnetic plate drives the sliding plate to move outward, leaving a vacancy on the relative side of the two sliding plates for the scraper to pass through, avoiding running interference. Thus, when the sliding plate passes through the scraper, it remains open, enabling the scraper to clean the surface of the conveyor belt, reducing the residue of garbage, and keeping the surface of the conveyor belt relatively clean.

[0020] The present invention provides a garbage treatment and classification screening device. It has the following beneficial effects:

[0021] 1. The present invention collects iron waste through the magnetic separation cylinder, and when the conveying plate rotates, it drives the garbage to circulate in the screening box, dispersing the garbage to avoid accumulation, which can effectively improve the collection effect of the magnetic separation cylinder on iron waste.

[0022] 2. After the magnetic separation cylinder is inserted, through the automatic docking of the elastic telescopic rod and the connecting groove, when the plate rotates, it drives the magnetic separation cylinder to rotate through the elastic telescopic rod. When the magnetic separation cylinder rotates, it can adjust the overall adsorption area, enabling the entire magnetic separation cylinder to fully perform adsorption and utilization. Moreover, the magnetic separation cylinder does not require additional driving equipment, which can reduce costs, realize the multi-functional application of a single motor, and achieve the application of more functions with the least input of structure and equipment.

[0023] 3. When the box body moves and opens, through the blanking plate, the iron waste adsorbed on its surface can be scraped off when the magnetic separation cylinder moves through, achieving the effect of automatically removing the iron waste on the surface of the magnetic separation cylinder. And when the iron waste moves to the connecting section under the interception of the blanking plate, the magnetic force adsorbing the iron waste disappears, causing the waste to fall off, achieving the effect of completely cleaning and dropping the iron waste on the surface of the magnetic separation cylinder, and avoiding the iron waste from being adsorbed on the side end of the magnetic separation cylinder.

[0024] 4. The present invention closes and pushes garbage through two sliding plates, and automatically opens when the sliding plates pass through the scraper, so that the scraper passes through the gap between the sliding plates to clean the surface of the conveyor belt, reducing the residue of garbage and keeping the surface of the conveyor belt relatively clean.

[0037] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to the attached Figure 1 - attached Figure 5 As shown in the figure, an embodiment of the present invention provides a garbage treatment and classification screening device, including a recycling table 1. A U-shaped screening box 2 is arranged on the upper surface of the recycling table 1. The screening box 2 includes a U-shaped box main body 201 and side plates 202. A screening component 3 is installed inside the screening box 2. The screening component 3 includes a ring body 301, a circular plate body 302 and a magnetic separation cylinder 303. A plurality of annularly distributed conveyor plates 304 are slidably connected to the opposite sides of the ring body 301 and the circular plate body 302. The outer side wall of the plate body 302 is rotatably connected to the inner side wall of the side plate 202. A plurality of support rods 11 are fixedly connected to the opposite sides of the ring body 301 and the circular plate body 302. A motor 10 is fixedly connected to the outer wall of the side plate 202. The driving end of the motor 10 penetrates through the side plate 202 and is fixedly connected to the center of the plate body 302. The magnetic separation cylinder 303 is arranged inside the screening box 2, and one end of the magnetic separation cylinder 303 is rotatably connected to the side wall of the box main body 201. The conveyor plate 304 is made of ferromagnetic material.

[0039] Specifically, the ring body 301 is connected to the plate body 302 through the support rod 11. When in use, the screening box 2 is closed, and garbage is put into the screening box 2. The iron waste is collected by the magnetic separation cylinder 303. At this time, the motor 10 drives the plate body 302 to rotate, and the plate body 302 drives the conveying plate 304 to rotate, driving the garbage to circulate in the screening box 2 so that the garbage can be dispersed to avoid accumulation, which can effectively improve the collection effect of the magnetic separation cylinder 303 on iron waste. After the garbage screening is completed, the box body 201 is pushed to move away from the side plate 202 to open the screening box 2. At this time, the unabsorbed garbage in the screening box 2 is intercepted by the ring body 301 and gradually falls out when the box body 201 is withdrawn later. The effect of quickly discharging the screened garbage is achieved. When the subsequent screening box 2 is closed again, the magnetic separation cylinder 303 is inserted into the center of the annular conveying plate 304. The magnetic attraction between the magnetic separation cylinder 303 and the conveying plate 304 can drive the conveying plate 304 to slide and retract to the minimum amplitude as a whole, so that the conveying plate 304 is inserted into the box body 201 for use. When the screening box 2 is opened, the magnetic separation cylinder 303 and the conveying plate 304 are offset and the magnetic attraction disappears, so that the conveying plate 304 rotated to the lower area slides downward under the influence of gravity, thereby increasing the distance between the adjacent conveying plates 304 on the lower side, so that the garbage can fall better, thereby avoiding or reducing the problem of large pieces of garbage being stuck between the conveying plates 304.

[0040] Please refer to the attached Figure 3 -Attached Figure 4 An electric push cylinder 306 is coaxially arranged inside the magnetic separation cylinder 303, and a connecting piece 305 is fixedly connected to the outer cylinder body wall of the electric push cylinder 306, and the driving end of the electric push cylinder 306 is rotatably connected to the plate body 302, one end of the connecting piece 305 extends into the interior of the magnetic separation cylinder 303 and is rotatably connected to the magnetic separation cylinder 303, and the outer side wall of the connecting piece 305 is fixedly connected to the box body 201.

[0041] Specifically, the connecting piece 305 is used to connect the electric push cylinder 306, the magnetic separation cylinder 303 and the box body 201, so that when the electric push cylinder 306 is running, it synchronously drives the magnetic separation cylinder 303 and the box body 201 to move. When the electric push cylinder 306 is extended, it drives the magnetic separation cylinder 303 and the box body 201 to move away from the side plate 202, thereby achieving the effect of automatically opening the screening box 2. When the electric push cylinder 306 is contracted, it drives the magnetic separation cylinder 303 and the box body 201 to move in the direction facing the side plate 202, thereby achieving the effect of automatically closing the screening box 2.

[0042] Please refer to the attached Figure 2 -Attached Figure 4The outer wall of the side panel 202 is fixedly connected to the recycling platform 1 through the supporting leg 203, and the outer wall of the box body 201 is slidably connected to the upper surface of the recycling platform 1 through the slide plate 204. An iron recovery port 5 and a garbage separation port 6 are provided on the upper surface of the recycling platform 1. A partition 7 is provided between the iron recovery port 5 and the garbage separation port 6. The bottom end of the partition 7 is fixedly connected to the upper surface of the recycling platform 1, and the partition 7 is located directly below the ring body 301. An iron conveyor 16 is provided below the iron recovery port 5, and a garbage conveyor 17 is provided below the garbage separation port 6.

[0043] Specifically, the partition 7 is used to separate the iron recovery port 5 and the garbage separation port 6, and the side plate 202 is supported by the support leg 203, and the box body 201 is slidably supported by the sliding plate 913. When the screening box 2 is opened, the screened garbage inside it falls through the garbage separation port 6 and is transported away to the garbage conveyor 17 for further processing, and the iron waste is separated from the magnetic separation cylinder 303 and falls from the iron recovery port 5 to the iron conveyor 16 for recycling, thereby achieving the effect of recycling and utilizing iron solid waste and realizing the reuse of iron solid waste.

[0044] Please refer to the attached Figure 4 -Attached Figure 5 The side wall of the plate body 302 is fixedly connected with an elastic telescopic rod 307, which is a spring self-contracting telescopic rod. The elastic telescopic rod 307 is made of ferromagnetic material, and a connecting groove 308 is provided on the outer side wall of one end of the magnetic separation cylinder 303 facing the side plate 202.

[0045] Specifically, initially the elastic telescopic rod 307 remains contracted so that its bottom end is higher than the magnetic separation tube 303 to avoid operation interference when the magnetic separation tube 303 moves through. When the magnetic separation tube 303 passes through the elastic telescopic rod 307, the magnetic separation tube 303 applies magnetic suction to the elastic telescopic rod 307 so that the bottom end of the elastic telescopic rod 307 slides downward until it contacts the magnetic separation tube 303, and drives the elastic telescopic rod 307 to rotate when the plate body 302 rotates subsequently. When the elastic telescopic rod 307 rotates to align with the connecting groove 308, the elastic telescopic rod 307 extends again and is inserted into the connecting groove 308, thereby driving the magnetic separation tube 303 to rotate through the elastic telescopic rod 307 when the plate body 302 rotates. When the magnetic separation tube 303 rotates, the overall adsorption area can be adjusted, so that the magnetic separation tube 303 as a whole can be fully adsorbed and utilized, and the magnetic separation tube 303 does not require additional driving equipment, which can reduce costs, realize the multi-functional application of the single motor 10, and realize more functional applications with minimal investment in structure and equipment.

[0046] Please refer to the attached Figure 5The inner wall of the plate body 302 is fixedly connected with a plurality of telescopic connecting rods 309, and the other ends of the plurality of telescopic connecting rods 309 are commonly fixedly connected with a ring-shaped unloading plate 310, which is sleeved on the outer side of the magnetic separation cylinder 303. A notch is opened on the side wall of the box body 201, and a baffle 205 of a matching shape is arranged inside the notch, and a connecting column is fixedly arranged on the opposite side of the unloading plate 310 and the baffle 205.

[0047] Specifically, the maximum spacing of the telescopic connecting rod 309 is greater than the length of the support rod 11, and the minimum spacing of the telescopic rod is the same as the length of the support rod 11. Therefore, when the screening box 2 is closed, the unloading plate 310 is pushed to be in the ring body 301 to prevent garbage from falling into the ring body 301. When the screening box 2 is opened to drive the magnetic separation cylinder 303 to move, the unloading plate 310 drives the telescopic connecting rod 309 to extend under the push of the impurities adsorbed on the outside of the magnetic separation cylinder 303. When the unloading plate 310 is extended to the maximum extent, the unloading plate 310 stops moving. 0 has passed through the ring body 301, so that the iron waste and the screened garbage can fall on both sides of the ring body 301 respectively to avoid re-mixing, and at this time, the unloading plate 310 can scrape off the iron waste adsorbed on the surface of the magnetic separation cylinder 303 when it moves through, so as to achieve the effect of automatically removing the iron waste on the surface of the magnetic separation cylinder 303, and at this time, when the box body 201 moves, the baffle 205 remains stationary to intercept the fallen iron waste, and after the box body 201 and the baffle 205 are staggered, some of the fallen iron waste falls and is discharged.

[0048] Please refer to the attached Figure 4 The magnetic separation cylinder 303 includes a magnetic adsorption section 3031 and a non-magnetic connection section 3032, and the opening of the connection section 3032 is closed, leaving only a circular hole for the electric push cylinder 306 to pass through to prevent garbage from entering.

[0049] Specifically, when the magnetic separation cylinder 303 passes through the discharge plate 310 for cleaning and the connecting section 3032 passes through the discharge plate 310, the iron waste previously adsorbed on the adsorption section 3031 moves to the connecting section 3032 under the interception of the discharge plate 310. Since the connecting section 3032 has no magnetic attraction, this part of the iron waste will fall off, thereby achieving the effect of completely cleaning and dropping the iron waste on the surface of the magnetic separation cylinder 303, and preventing the iron waste from being adsorbed on the side end of the magnetic separation cylinder 303.

[0050] Please refer to the attached Figure 6 A tilted feed conveyor 8 is provided on one side of the recovery platform 1 , and a conveying assembly 9 is installed on the conveyor belt surface of the feed conveyor 8 . The conveying assembly 9 includes a plurality of conveying layers 91 , and the conveying layers 91 are arranged around the conveyor belt surface of the feed conveyor 8 .

[0051] Specifically, a plurality of storage spaces are demarcated on the surface of the feeding conveyor 8 through the conveying layer 91 for placing garbage, and when the feeding conveyor 8 conveys upward, it prevents the garbage from sliding down.

[0052] Please refer to the attached Figure 7 - attached Figure 9 , the conveying layer 91 includes two vertical slide rails 911 and magnetic plates 915. The vertical slide rails 911 are fixedly arranged on the surface of the conveyor belt of the feeding conveyor 8. A horizontal slide rail 912 is slidably connected inside the vertical slide rail 911. One side of the horizontal slide rail 912 is provided with a sliding plate 913. A chute is formed on the surface of the sliding plate 913, and the chute is slidably connected with one end of the horizontal slide rail 912. A side wall of the chute is fixedly connected with an elastic member 914. The elastic member 914 can be a leaf spring, a helical spring, a torsion bar spring, a rubber spring, etc. In this embodiment, a helical spring is adopted. The other end of the elastic member 914 is fixedly connected with the horizontal slide rail 912. The sliding plate 913 is made of a ferromagnetic material. Two magnetic plates 915 are provided and are respectively fixedly arranged on the upper walls of both sides of the frame of the feeding conveyor 8. The conveying assembly 9 further includes a fixed bracket 92. One end of the fixed bracket 92 is fixedly connected with the inner side wall of the side plate 202. A T-shaped scraper 93 is fixedly arranged on the upper surface of the fixed bracket 92. The top end of the scraper 93 fits the conveyor belt of the feeding conveyor 8.

[0053] Specifically, the elastic force of the elastic member 914 pushes the sliding plate 913, so that the two sliding plates 913 are closed to push the garbage. When the sliding plate 913 moves to the lower side of the feeding conveyor 8, the horizontal slide rail 912 slides down along the vertical slide rail 911 under the action of gravity, so that a certain gap is maintained between the sliding plate 913 and the conveyor belt. At the same time, when the sliding plate 913 moves past the magnetic plate 915, the magnetic attraction of the magnetic plate 915 drives the sliding plate 913 to move outward, so that a vacancy is left on the relative side of the two sliding plates 913 for the scraper 93 to pass through, avoiding running interference. Thus, the sliding plate 913 remains open when passing through the scraper 93, so that the scraper 93 passes through the vacancy between the two sliding plates 913 to clean the surface of the conveyor belt, reducing the residue of garbage and keeping the surface of the conveyor belt relatively clean.

[0054] Please refer to the attached Figure 7 , for two corresponding sliding plates 913, one end of one of them protrudes outward to form an insertion block 12, and one end of the other one is recessed inward to form a groove 13. When the two sliding plates 913 are butted, the insertion block 12 is inserted into the inside of the groove 13, thereby connecting the two sliding plates 913, which can improve the fastening of the butt joint of the sliding plates 913.

[0055] Please refer to the attached Figure 8, a side guard plate 14 is fixedly arranged on the upper surface of the frame of the feeding conveyor 8. The distance between the two side guard plates 14 is the same as the length when the two sliding plates 913 are butted. Thus, while preventing the garbage from falling laterally through the side guard plate 14, the sliding plate 913 is laterally limited. A limiting layer 15 is fixedly arranged on the side wall of the side guard plate 14. The distance between the limiting layer 15 and the frame is the same as the height of the sliding plate 913. When the sliding plate 913 moves below the limiting layer 15, the sliding plate 913 is vertically limited by the limiting layer 15 to maintain the stability of the sliding plate 913 when conveying garbage. The bottom end of the limiting layer 15 is partially upturned to form a bend. At the same time, the bottom end of the side guard plate 14 is partially bent outwards so that the sliding plate 913 can pass through the limiting layer 15 and the side guard plate 14 better.

[0056] Please refer to the appendix Figure 10 - appendix Figure 11 , a buffer plate 18 is rotatably connected to the inner side wall of the garbage separation opening 6 through a shaft. The upper surface of the buffer plate 18 is rotatably connected to a shaking rod 19 through a universal coupling. A fixing seat 20 is arranged outside the shaking rod 19. One end of the fixing seat 20 is fixedly connected to the partition plate 7. The upper surface of the fixing seat 20 is rotatably connected to a rotating plate 21 through a shaft. A flexible connecting rope 22 is fixedly arranged on the lower surface of the rotating plate 21. The bottom end of the connecting rope 22 is fixedly connected to the shaking rod 19. The lower surface of the box body 201 is rotatably connected to a plurality of pressing plates 23 through a shaft. And the connecting rotating shaft of the pressing plate 23 is arranged on the side away from the side plate 202. A through hole for the pressing plate 23 to pass through is opened on the upper surface of the partition plate 7.

[0057] Specifically, by obliquely arranging the buffer plate 18, the falling garbage can be intercepted, the impact force on the garbage conveyor 17 when the garbage falls can be buffered, and the service life of the garbage conveyor 17 can be prolonged. And when the box body 201 moves and opens, it drives the pressing plate 23 to move laterally and pass through the rotating plate 21 in sequence. By the movement of the pressing plate 23 to press the rotating plate 21, the rotating plate 21 is driven to rotate. The rotating plate 21 rotates and pulls the connecting rope 22 upwards through the connecting rope 22, and the shaking rod 19 drives the buffer plate 18 to move upwards. And after the pressing plate 23 and the rotating plate 21 are staggered, the buffer plate 18 moves downwards. Thus, the buffer plate 18 generates shaking, so that the garbage on the buffer plate 18 can slide better, preventing the garbage from accumulating on the buffer plate 18. There is no need to set a vibrator, thus the cost can be saved.
