Description

Technical Field

[0001] This invention belongs to the field of screening and recycling technology, specifically relating to an energy-saving solid waste recycling and processing equipment. Background Technology

[0002] In the field of solid waste recycling, the efficient separation and recovery of metal components is a crucial step in achieving resource recycling. Currently, most common metal recovery methods employ magnetic separation technology, but existing equipment and processes still have several significant shortcomings in practical applications: Low sorting efficiency and poor process continuity: Traditional magnetic separators often design feeding, magnetic separation, and unloading processes as step-by-step or intermittent operations, with waiting time between each process, making it impossible to achieve continuous material processing and limiting the improvement of overall processing capacity and recycling efficiency.

[0003] Poor magnetic separation effect and recovery rate need to be improved: In many existing equipment, the material is in a static or simple translational state during the magnetic separation process, which makes it difficult for the metal material that is wrapped or located at the bottom to be fully exposed to the magnetic field, which easily leads to missed selection and reduces the metal recovery rate.

[0004] Severe equipment wear and high maintenance costs: After magnetic separation, the material is often removed from the magnetic separator drum by rigid contact methods such as scrapers. Long-term operation can easily lead to wear on the scraper and drum surfaces, which not only affects the separation effect, but also requires frequent shutdowns to replace parts, increasing operating and maintenance costs.

[0005] High energy consumption and insufficient energy conservation and environmental protection: Traditional equipment has complex drive systems and lacks effective energy recovery or reuse designs, resulting in high overall energy consumption. At the same time, few equipment uses clean energy sources such as solar energy as supplementary power, which falls short of current green and low-carbon production requirements.

[0006] Therefore, there is an urgent need to develop an integrated equipment that combines continuous vibration feeding, high-efficiency magnetic separation, flexible unloading, and energy-saving drive to solve the problems of low sorting efficiency, incomplete metal recovery, easy wear and high energy consumption in existing technologies, and to meet the urgent needs of modern solid waste resource utilization for high efficiency, low loss and energy saving and environmental protection.

[0015] In a preferred embodiment of an energy-saving solid waste recycling and treatment equipment, one side of the magnetic separation chamber is fixed to the recycling screening frame. The length of the magnetic separation chamber is greater than the width of the recycling screening frame assembly. The output end of the magnetic separation hydraulic cylinder is fixed to the top platform of the base frame. The T-shaped slider slides in the U-shaped hanger through the T-shaped slide groove.

[0016] In a preferred embodiment of an energy-saving solid waste recycling and treatment equipment, the sliding base platforms at the top of the first contact pusher plate and the second contact pusher plate slide on a U-shaped base frame via two base frame sliding grooves.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention has a magnetic separation roller assembly at the rear end of the recycling screening frame assembly for magnetic separation of the vibrating material on the recycling feed tray assembly. The magnetic separation roller assembly is equipped with a magnetic separation roller pusher assembly that elastically pushes out the magnetically separated material. In actual use, the magnetic separation roller performs magnetic separation on the material on the recycling feed tray assembly, screening out metal materials and magnetic materials. At the same time, during the magnetic separation process of the magnetic separation roller, the magnetic separation roller pusher assembly is controlled by the magnetic separation hydraulic cylinder to move laterally in the magnetic separation chamber. The magnetically separated material on the magnetic separation roller is pushed out by the second contact pusher plate and the first contact pusher plate, realizing the synchronous operation of magnetic separation and feeding.

[0019] 2. A powerful magnet is provided at one end of the electromagnetic gear arm of the present invention. When the electromagnet is energized, it generates magnetic force, which pushes the electromagnetic gear arm backward through the powerful magnet. At this time, the electromagnetic gear arm drives the push shaft to rotate clockwise through meshing with the first push gear. When the push shaft rotates clockwise, it meshes with the two push gear arms, causing the first contact push plate and the second contact push plate to move away from each other. At this time, the first contact push plate and the second contact push plate do not contact the magnetic separation roller, thus avoiding contact wear when not pushing material.

[0020] 3. The bottom of the recycling and screening frame assembly of the present invention is provided with a recycling feeding tray assembly for inclined vibration feeding. The vibration feeding and vibration turning process of solid waste, the magnetic separation recycling process and the magnetic separation material dropping process of the present invention do not interfere with each other and can be carried out simultaneously, thereby improving the efficiency of solid waste recycling.

[0049] The working principle of this invention is as follows: Metals in solid waste have high recycling value. However, there is a lack of devices for quickly recovering metals from solid waste during recycling, hindering resource reuse. Furthermore, existing technologies use magnets for metal sorting, but this method cannot simultaneously sort and feed the material, resulting in low efficiency. To overcome these problems, the rear end of the recycling screening frame assembly 100 of this invention is equipped with a recycling magnetic separation roller assembly 300 for magnetically separating the vibrating material on the recycling feeding tray assembly 200. The recycling magnetic separation roller assembly 300 contains a magnetic separation roller pusher assembly 400 that elastically pushes the magnetically separated material. Specifically, one side of the magnetic separation bin 301 is fixed to the recycling screening frame. On 101, the length of the magnetic separation chamber 301 is greater than the width of the recycling screening frame assembly 100. The output end of the magnetic separation hydraulic cylinder 304 is fixed on the top platform 410 of the base frame. The T-shaped slider 503 slides in the U-shaped hanger 413 through the T-shaped slide groove 412. The push shaft 401 is rotated and set at the top of the T-shaped slide groove 412. The electromagnetic toothed arm 501 meshes with the push shaft 401. The strong magnet 502 is directly opposite the electromagnet 408. The toothed arm end plate 504 is directly opposite the end of the U-shaped base frame 411 away from the electromagnet 408. At this time, the two ends of the toothed arm clamping spring 505 are respectively fixed on the toothed arm end plate 504 and the frame of the U-shaped base frame 411 away from the electromagnet 408. The first contact pusher plate 407 and the second contact pusher plate 414 are connected. The top slide base 405 slides on the U-shaped base 411 via two base base slide grooves 409. The pushing gear arms 404 on the top of the first contact pusher plate 407 and the second contact pusher plate 414 are respectively located on both sides of the second pusher gear 403. The two sides of the second pusher gear 403 mesh with the pushing gear arms 404 on the top of the first contact pusher plate 407 and the second contact pusher plate 414 respectively. The second contact pusher plate 414 and the first contact pusher plate 407 abut against the outer wall of the magnetic separation roller 302. In actual use, the electromagnetic gear arm 501 is pushed by the gear arm clamping spring 505, and the electromagnetic gear arm 501 slides in the U-shaped hanger 413. At this time, the electromagnetic... The gear arm 501 meshes with the first push gear 402, driving the push shaft 401 to rotate counterclockwise. At this time, the push shaft 401 meshes with the two push gear arms 404 through the second push gear 403, causing the first contact push plate 407 and the second contact push plate 414 to form a contact approach mechanism. At this time, the first contact push plate 407 and the second contact push plate 414 abut against both sides of the magnetic separation roller 302. In actual use, the magnetic separation roller 302 performs magnetic separation on the material on the recovery feed tray assembly 200, screening out metal materials and magnetic materials. At the same time, during the magnetic separation process of the magnetic separation roller 302, the magnetic separation roller push assembly 400 is controlled to move laterally within the magnetic separation chamber 301 by the magnetic separation hydraulic cylinder 304.The magnetically separated material on the magnetic separation roller 302 is pushed out by the second contact pusher plate 414 and the first contact pusher plate 407, achieving synchronous magnetic separation and unloading. Simultaneously, the contact between the second contact pusher plate 414 and the first contact pusher plate 407 on the magnetic separation roller 302 is pushed by the elastic force of the toothed arm clamping spring 505. Through the elastic action of the toothed arm clamping spring 505, on the one hand, the second contact pusher plate 414 and the first contact pusher plate 407 are prevented from making hard contact with the magnetic separation roller 302; on the other hand, when wear occurs on the second contact pusher plate 414 and the first contact pusher plate 407, this elastic contact structure ensures that the second contact pusher plate 414 and the first contact pusher plate 407 always remain in contact with the magnetic separation roller 302, thus facilitating the subsequent pushing of the magnetically separated material off the magnetic separation roller 302.

[0050] Based on the above, when it is not necessary to push the magnetic material through the second contact pusher plate 414 and the first contact pusher plate 407, in order to avoid wear between the second contact pusher plate 414 and the first contact pusher plate 407 and the magnetic separation roller 302, a strong magnet 502 is provided at one end of the electromagnetic gear arm 501. The T-shaped slider 503 slides in the U-shaped hanger 413 through the T-shaped slide groove 412. The pusher shaft 401 is rotated and set at the top of the T-shaped slide groove 412. The electromagnetic gear arm 501 meshes with the pusher shaft 401, and the strong magnet 502 is directly opposite the electromagnet 408. At this time, it is only necessary to energize the electromagnet 408. Magnet 408 generates magnetic force, and the magnetic force of electromagnet 408 pushes electromagnetic gear arm 501 to move backward through strong magnet 502. At this time, electromagnetic gear arm 501 drives push shaft 401 to rotate clockwise through meshing with first push gear 402. When push shaft 401 rotates clockwise, push shaft 401 meshes with two push gear arms 404, causing the first contact push plate 407 and the second contact push plate 414 to move away from each other. At this time, the first contact push plate 407 and the second contact push plate 414 do not contact the magnetic separation roller 302, avoiding contact wear when not pushing material.

[0051] Based on the above, in order to ensure a better magnetic separation effect of the magnetic separation roller 302 on the solid waste on the recycling feed tray assembly 200, the bottom of the recycling screening frame assembly 100 of this invention is provided with a recycling feed tray assembly 200 for inclined vibration feeding. The bottom arm of the main vibration arm 206 is rotatably mounted on the end platform 109. The L-shaped guide sliding seat 209 slides on the guide sliding rod 110 through the guide sliding hole 208. The vibration spring 205 is sleeved on the guide sliding rod 110, with one end of the vibration spring 205 abutting against the L-shaped guide sliding seat 209 and the other end abutting against the guide sliding rod 110. Through the pushing of the L-shaped guide sliding seat 209 by the vibration spring 205, the arc-shaped arm 210 at the bottom of the feed tray 201 is in a downward contact structure, and the arc-shaped arm 210 abuts against the cam 108. At this time, the arc-shaped arm 210 passes through the seat groove 103 through the seat platform 104. In actual use... The drive motor 106 drives the cam 108 to rotate, and the cam 108 frequently pushes the arc-shaped arm 210, thereby causing the recycling feed tray assembly 200 to vibrate at the bottom of the recycling screening frame assembly 100. Since the recycling feed tray assembly 200 is inclined at the bottom of the recycling screening frame assembly 100, the vibration of the recycling feed tray assembly 200 allows the solid waste on the recycling feed tray assembly 200 to slowly pass under the recycling magnetic separation roller assembly 300. At the same time, this inclined vibration allows the solid waste on the recycling feed tray assembly 200 to vibrate and turn over, ensuring that the metal or magnetic materials in the solid waste can be fully exposed, facilitating the magnetic separation of the recycling magnetic separation roller assembly 300. In this invention, the vibration feeding and turning process of solid waste, the magnetic separation recycling process, and the falling process of the magnetically separated material do not interfere with each other and can be carried out simultaneously, improving the efficiency of solid waste recycling.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
