Description

Technical Field

[0001] This invention relates to the technical field of resource recycling and reuse, specifically to a crushing and filtering mechanism for recycling special copper materials. Background Technology

[0002] Crushing and filtering equipment typically consists of a crushing device and a filtering device. It can crush materials into fine particles and remove impurities and unwanted components through the filtering device. Adopting an environmentally friendly and energy-saving design concept, it can reduce energy consumption and environmental pollution. It usually adopts an automated control system to achieve automated crushing and filtering, reduce manual labor intensity, and improve production efficiency. The crushing and filtering mechanism for special copper material recycling is a very practical piece of equipment. It can efficiently crush and filter special copper materials, improve the efficiency and quality of recycling, and at the same time reduce energy consumption and environmental pollution.

[0003] The current equipment still has many inconveniences in its use;

[0004] The specific defects are as follows:

[0005] Firstly, in the recycling of special copper materials, the crushed material is filtered through a filter screen to remove impurities and larger particles. The crushed material of special copper materials is sticky or finely chopped, which easily adheres to the filter screen and gradually accumulates. As filtration continues, impurities gradually accumulate on the filter screen, causing it to become clogged and affecting filtration efficiency. Moreover, since the filter screen is usually located inside the equipment, it is difficult to clean the impurities on the surface of the filter screen. Traditional cleaning methods require stopping the machine and disassembling the filter screen, and the existing disassembly process is cumbersome, requiring the entire device to be disassembled. This is not only time-consuming and labor-intensive, but also affects production efficiency.

[0006] Secondly, during the recycling of special copper materials, due to their stickiness, corrosiveness, or other special properties, prolonged contact between these materials and the filter screen can lead to clogging, wear, or damage. Furthermore, during the crushing and filtration process, impurities and particles in the special copper materials gradually accumulate on the filter screen. Prolonged friction can cause the filter screen pores to enlarge, affecting the filtration effect. Since existing filter screens are usually fixed inside the filtration mechanism to ensure sealing, they are inconvenient to replace. Filter screens that have been used for a long time will need to be replaced due to clogging or wear. The filter screen replacement process is complex and time-consuming, which will increase equipment downtime and reduce production efficiency.

[0007] Therefore, this invention proposes a special copper material recycling crushing and filtering mechanism to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0008] (a) Technical problems to be solved

[0009] To address the shortcomings of existing technologies, this invention provides a special copper material recycling crushing and filtration mechanism, which solves the problems mentioned in the background art, such as easy clogging and difficulty in cleaning of the filter screen surface and difficulty in replacing the filter screen inside the device.

[0012] The flipping mechanism includes an adjustable sliding bottom frame that controls the reverse flipping of the filter screen;

[0013] The fixing mechanism includes a side block for controlling the fixing state of the filter screen.

[0014] The flipping mechanism includes a sliding adjustment block slidably connected to the inside of the filter top frame. An adjustable sliding bottom frame is slidably connected to the inside of the filter top frame. An adjustable sliding top frame, which is inverted L-shaped, is fixedly connected to the surface of the adjustable bottom frame. A central rotating shaft is rotatably connected inside the sliding adjustment block. A sliding crossbar is fixedly connected to one end of the central rotating shaft near the adjustable bottom frame. A rotating lever, also L-shaped, is fixedly connected to the surface of the sliding crossbar. Both ends of the rotating lever are fixedly connected to actuating shafts. A surface-fitting slider is fixedly connected to the surface of the adjustable sliding base frame. The surface-fitting slider is triangular. An outer sleeve rod is fixedly connected to the surface of the end of the central rotation axis away from the surface-fitting slider. A limit fixing shaft is fixedly connected to the surface of the sliding adjustment block. A second pull shaft is fixedly connected to the end of the outer sleeve rod away from the central rotation axis. A bottom pull rod is fixedly connected to the lower surface of the sliding adjustment block. A first pull shaft is fixedly connected to the surface of the bottom pull rod. Fixed hooks are fixedly connected to the surfaces of both the second pull shaft and the first pull shaft. A pull spring is fixedly connected between the two fixed hooks.

[0015] The horizontal portion of the adjusting sliding base frame is located within the sliding path of the actuating circular shaft, and the limiting fixing shaft is located on the rotation path of the outer sleeve rod.

[0016] The filter top frame has a rotating groove inside, and the height of the adjustable sliding bottom frame is equal to the height of the rotating groove inside the filter top frame.

[0017] The adjustable sliding base frame surface has two horizontal portions, and the two horizontal portions of the adjustable sliding base frame surface are symmetrical about the sliding crossbar.

[0018] The fixing mechanism includes a sliding push rod, which is slidably connected to the inside of the filter top frame. A sliding crossbar is slidably connected to the inside of the sliding push rod. A sliding filter plate is slidably connected to the inside of the filter top frame. The sliding push rod is slidably connected to the inside of the sliding filter plate. A side block is fixedly connected to the end of the sliding crossbar away from the sliding adjustment block. A center crossbar is slidably connected to the inside of the sliding crossbar. An outer push plate is slidably connected to the surface of the sliding crossbar. A center crossbar is slidably connected to the inside of the sliding crossbar. The center crossbar and the outer push plate are fixedly connected. A second spring is fixedly connected to the inside of the sliding crossbar. The second spring and the center crossbar are fixedly connected. A locking block is slidably connected to the inside of the sliding push rod. A first spring is fixedly connected between the sliding push rods. The first spring and the locking block are fixedly connected.

[0019] There are two locking blocks, which are arranged symmetrically about the second spring.

[0020] The side of the locking block away from the side block is set as an inclined surface, and the side of the side block away from the sliding adjustment block is set as an inclined surface.

[0021] (III) Beneficial Effects

[0022] The special copper material recycling crushing and filtering mechanism provided by this invention has the following beneficial effects:

[0023] 1. By using the filter top frame in conjunction with the flipping mechanism, the sliding filter plate inside the device is flipped over, and then the material on the surface of the sliding filter plate is cleaned by vibration. This solves the problem of easy clogging and difficulty in cleaning the filter screen surface. When one side of the sliding filter plate is blocked by impurities, the flipping mechanism flips the sliding filter plate over and cleans the surface of the sliding filter plate by vibration, reducing cleaning resistance and improving cleaning efficiency. Furthermore, since the impurities are evenly distributed on both sides of the sliding filter plate, rather than concentrated on one side, the flipping mechanism can reduce local wear of the sliding filter plate, extend the service life of the sliding filter plate, and reduce operating costs.

[0024] 2. By using the filter top frame in conjunction with the fixing mechanism, and by releasing the fixed state between the sliding push rod and the sliding crossbar, the sliding adjustment block can be pulled out from inside the device. This allows the device to be opened and the sliding adjustment block to be directly removed, thus replacing the sliding filter plate. This solves the problem of the sliding filter plate inside the device being difficult to replace. Timely replacement of worn or clogged adjusting sliding bottom frames ensures the filtration effect of the crushing and filtering mechanism. Maintaining good filtration performance helps improve the quality of recycled special copper materials and reduces the impact of impurities on subsequent processes. Furthermore, the design of easy-to-replace adjusting sliding bottom frames allows for the selection of appropriate adjusting sliding bottom frame specifications and materials according to different recycling needs and material characteristics. This allows for flexible adjustment of filtration accuracy and processing capacity to adapt to diverse special copper material recycling tasks.

[0025] 3. By using the flipping mechanism in conjunction with the fixing mechanism, the flipping mechanism controls the fixing state of the sliding filter plate. The flipping mechanism can flip the sliding filter plate to a fixed position, and the fixing of the sliding filter plate can only be released when it reaches the fixed position. This reduces the chance of the operator coming into contact with the filter screen, reducing the risk of accidental injury. In addition, the flipping mechanism can quickly flip the sliding filter plate to a fixed position, thereby reducing the time the operator spends adjusting the position of the sliding filter plate and improving operating efficiency.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] refer to Figures 1 to 9 According to a preferred embodiment of the present invention, a special copper material recycling crushing and filtering mechanism will be described in detail below. The special copper material recycling crushing and filtering mechanism includes a support 1, a filter top frame 2 is fixedly connected to the top of the support 1, a flipping mechanism 3 for cleaning the filter screen surface is provided inside the filter top frame 2, and a fixing mechanism 4 for easy filter screen replacement is provided inside the filter top frame 2.

[0041] The flipping mechanism 3 includes an adjustable sliding bottom frame 312 for controlling the reverse flipping of the filter screen;

[0042] The fixing mechanism 4 includes a side block 413 for controlling the fixing state of the filter screen.

[0043] The flipping mechanism 3 includes a sliding adjustment block 311, which is slidably connected to the inside of the filter top frame 2. An adjusting sliding bottom frame 312 is slidably connected to the inside of the filter top frame 2. An adjusting sliding top frame 313, which is L-shaped, is fixedly connected to the surface of the adjusting bottom frame 312. A central rotating shaft 318 is rotatably connected inside the sliding adjustment block 311. A sliding crossbar 314, which is L-shaped, is fixedly connected to the end of the central rotating shaft 318 near the adjusting bottom frame 312. A rotating lever 315, which is inverted L-shaped, is fixedly connected to the surface of the sliding crossbar 314.

Fixed hooks 3115 are fixedly connected to the surfaces of both the second pull shaft 3114 and the first pull shaft 3112. A pull spring 3113 is fixedly connected between the two fixed hooks 3115. The horizontal part of the adjusting sliding bottom frame 312 is located within the sliding path of the actuating round shaft 316. The limiting fixed shaft 3110 is located on the rotation path of the outer sleeve rod 319. A rotation groove is opened inside the filter top frame 2. The height of the adjusting sliding bottom frame 312 is equal to the height of the rotation groove inside the filter top frame 2. There are two horizontal parts on the surface of the adjusting sliding bottom frame 312. The two horizontal parts on the surface of the adjusting sliding bottom frame 312 are symmetrically arranged about the sliding crossbar 314.

[0044] The effects achieved by this embodiment are as follows: In the special copper material recycling process, the crushed material is filtered through a filter screen to remove impurities and larger particles. The crushed material of the special copper material may be sticky or finely chopped, easily adhering to the filter screen and gradually accumulating. As filtration proceeds, impurities gradually accumulate on the filter screen, causing it to become clogged. By flipping the sliding filter plate 412 inside the device and replacing the material collection frame inside the device, and then using vibration to collect and clean the material on the surface of the sliding filter plate 412, the problem of easy clogging and difficulty in cleaning the filter screen surface is solved. When one side of the sliding filter plate 412 is clogged by impurities, flipping the sliding filter plate 412 and cleaning the surface of the sliding filter plate 412 by vibration reduces cleaning resistance and improves cleaning efficiency.

[0045] The fixing mechanism 4 includes a sliding push rod 411, which is slidably connected to the inside of the filter top frame 2. A sliding crossbar 314 is slidably connected to the inside of the sliding push rod 411. A sliding filter plate 412 is slidably connected to the inside of the filter top frame 2. The sliding push rod 411 is slidably connected to the inside of the sliding filter plate 412. A side block 413 is fixedly connected to the end of the sliding crossbar 314 away from the sliding adjustment block 311. A center crossbar 418 is slidably connected to the inside of the sliding crossbar 314. An outer push plate 417 is slidably connected to the surface of the sliding crossbar 314. The center crossbar 418 is slidably connected to the inside of the sliding crossbar 314. Rod 418 is fixedly connected to outer push plate 417. A second spring 416 is fixedly connected inside sliding crossbar 314. The second spring 416 is fixedly connected to central crossbar 418. A locking block 415 is slidably connected inside sliding push rod 411. A first spring 414 is fixedly connected between sliding push rods 411. The first spring 414 is fixedly connected to locking block 415. There are two locking blocks 415. The two locking blocks 415 are symmetrically arranged about the second spring 416. The side of locking block 415 away from side block 413 is set as an inclined surface. The side of side block 413 away from sliding adjustment block 311 is set as an inclined surface.

[0046] The effects achieved by this embodiment are as follows: During the crushing and filtration process, impurities and particles in the special copper material gradually accumulate on the filter screen. Long-term friction will cause the filter screen pore size to increase, affecting the filtration effect. Since the existing filter screen is usually fixed inside the filtration mechanism to ensure sealing, it is not convenient to replace. The filter screen will need to be replaced due to blockage or wear after long-term use. The filter screen replacement process is complicated and time-consuming, which will increase the downtime of the equipment and reduce production efficiency. The locking block 415 enters the interior of the sliding push rod 411 under the push of the inclined surface of the outer push plate 417, thereby releasing the fixed state between the sliding push rod 411 and the sliding crossbar 314, thereby pulling the sliding adjustment block 311 out of the device. The device can be opened and the sliding filter plate 412 can be taken out directly for replacement. This solves the problem that the sliding filter plate 412 inside the device is not easy to replace. Timely replacement of worn or blocked sliding filter plates 412 can ensure the filtration effect of the crushing and filtration mechanism. Maintaining good filtration performance helps to improve the quality of recycled special copper materials.

[0047] The following is the complete working process and working principle of the above embodiments:

[0048] Initially: The filter top frame 2 is equipped with an electric telescopic rod. The sliding adjustment block 311 is fixedly connected to the electric telescopic rod. The rotating shaft 316 is in contact with the surface of the sliding block 317. The pulling spring 3113 is in an unstretched state. The locking block 415 is located inside the limiting groove of the sliding crossbar 314. The second spring 416 and the first spring 414 are both in an uncompressed state. The outer push plate 417 is located at the end of the locking block 415 near the side block 413. The sliding crossbar 314 is located inside the sliding push rod 411.

[0049] During operation: When the crushed special copper material adheres to and gradually accumulates on the filter screen, clogging it, the device is opened to replace the internal material receiving frame. Since the sliding adjusting block 311 is fixedly connected to the electric telescopic rod, when cleaning the filter screen surface, the electric telescopic rod pushes the sliding adjusting block 311 upwards. The upward movement of the sliding adjusting block 311, through the sliding crossbar 314, drives the rotating lever 315 upwards. Because the horizontal portion of the adjusting sliding top frame 313 is located within the sliding path of the actuating shaft 316, the sliding crossbar 314 slides upwards, and the actuating shaft 316 contacts the horizontal portion of the adjusting sliding top frame 313, providing a thrust to the actuating shaft 316, thereby driving the rotating lever 315 upwards. The movable lever 315 rotates around the sliding crossbar 314 inside the rotating groove of the filter top frame 2. Since the sliding crossbar 314 is fixedly connected to the central rotating shaft 318 and the outer sleeve 319 is fixedly connected to the surface of the central rotating shaft 318, the rotation of the sliding crossbar 314 drives the outer sleeve 319 to rotate through the central rotating shaft 318. The second pull shaft 3114 is stretched under the pull of the second pull shaft 3114. When the rotation angle of the outer sleeve 319 exceeds 90 degrees, the outer sleeve 319 limits the rotation of the sliding crossbar 314 under the pull of the second pull shaft 3114, thereby flipping the sliding filter plate 412 on the surface of the sliding push rod 411 by 180 degrees through the sliding crossbar 314.

[0050] When the sliding filter plate 412 is flipped, the sliding adjustment block 311 is slid downwards via the electric telescopic rod, opening the device and replacing the material collection frame inside the filter top frame 2. The vibration during device operation shakes down the clogging material on the surface of the sliding filter plate 412, which is then collected by the new material collection frame. By flipping the sliding filter plate 412 inside the device and then cleaning the material on its surface through vibration, the problem of easy clogging and difficulty in cleaning the filter screen surface is solved. When one side of the sliding filter plate 412 is clogged by impurities, the flipping mechanism 3 flips the sliding filter plate 412, and the vibration cleans the clogging material on the surface of the sliding filter plate 412. The new material collection frame collects the clogging material on the surface of the sliding filter plate 412, reducing cleaning resistance and improving cleaning efficiency. Furthermore, since the impurities are evenly distributed on both sides of the sliding filter plate 412, rather than concentrated on one side, the flipping mechanism 3 can reduce local wear on the sliding filter plate 412, extend the service life of the sliding filter plate 412, and reduce operating costs.

[0051] Furthermore, when materials with special properties come into prolonged contact with the filter screen, causing it to become clogged, worn, or damaged, necessitating replacement, the sliding push rod 411 is manually pushed towards the adjusting sliding base frame 312. Since the sliding crossbar 314 has an internal locking groove, and the locking block 415 is located within this groove, and the sliding push rod 411 secures the sliding filter plate 412, when replacing the sliding filter plate 412, the sliding push rod 411 is manually pushed towards the adjusting sliding base frame 312. The bottom frame 312 slides in the direction of adjustment. Since the side of the locking block 415 near the adjusting sliding bottom frame 312 is set as an inclined surface, the sliding push rod 411 slides in the direction of adjusting sliding bottom frame 312. The inclined surface of the locking block 415 fits with the surface limiting groove of the sliding crossbar 314, thereby giving the locking block 415 an upward force, thus pushing the locking block 415 to slide in the direction of the first spring 414. The first spring 414 is compressed under the push of the locking block 415. When the outer push plate 417 contacts the locking block 415, the locking block 415 is pushed by the outer push plate 417. Under the push of spring 17, the locking block 415 is completely inside the sliding push rod 411. When the locking block 415 is located on the side of the outer push plate 417 away from the side block 413, the locking block 415 is located inside the sliding path of the outer push plate 417 under the push of spring 1 414. By manually pushing the sliding push rod 411 to slide away from the sliding crossbar 314, the locking block 415 contacts the outer push plate 417, and pushes the outer push plate 417 to slide towards the side block 413. Due to the center crossbar 418 and spring 2 416 The device is fixedly connected and the second spring 416 is compressed by the central crossbar 418. As the outer push plate 417 slides towards the side block 413 under the push of the locking block 415, the inner limiting groove of the sliding crossbar 314 is blocked. When the side block 413 is in contact with the outer push plate 417, the locking block 415 enters the interior of the sliding push rod 411 under the push of the inclined surface of the outer push plate 417, thereby releasing the fixed state between the sliding push rod 411 and the sliding crossbar 314, thereby pulling the sliding adjustment block 311 out of the device.

[0052] The device can be opened to directly remove the sliding filter plate 412 for replacement, solving the problem of the sliding filter plate 412 being difficult to replace inside the device. Timely replacement of worn or clogged adjusting sliding bottom frame 312 ensures the filtration effect of the crushing and filtering mechanism. Maintaining good filtration performance helps improve the quality of recycled special copper materials and reduces the impact of impurities on subsequent processes. The design of easy-to-replace adjusting sliding bottom frame 312 allows for the selection of appropriate specifications and materials according to different recycling needs and material characteristics. This allows for flexible adjustment of filtration accuracy and processing capacity to adapt to diverse special copper material recycling tasks.

[0053] 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.
