Description

Technical Field

[0001] The invention relates to the technical field of resource recovery and reuse, and in particular to a crushing and filtering mechanism for recovering special copper materials. Background Art

[0002] The crushing and filtering equipment is usually composed of a crushing device and a filtering device. It can crush the material into fine particles and remove impurities and unnecessary components through the filtering device. It adopts an environmentally friendly and energy-saving design concept, which 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 recycling special copper materials is a very practical equipment. It can efficiently crush and filter special copper materials, improve recycling efficiency and quality, and also reduce energy consumption and environmental pollution.

[0003] There are still many inconveniences in the use of current equipment;

[0004] The specific defects are as follows:

[0005] First, in the process of recycling special copper materials, the crushed materials will be filtered through a filter to remove impurities and larger particles. The crushed special copper materials are sticky or finely divided, and are easy to adhere to the filter and gradually accumulate. As the filtration proceeds, impurities will gradually accumulate on the filter, causing the filter to be blocked, affecting the filtration efficiency. Moreover, since the filter is usually located inside the equipment, it is difficult to clean the impurities on the surface of the filter. The traditional cleaning method requires shutting down and disassembling the filter, and the existing disassembly process is cumbersome and requires the entire device to be disassembled, which is not only time-consuming and labor-intensive, but also affects production efficiency.

[0006] Secondly, during the recycling process of special copper materials, since the special copper materials have sticky, corrosive or other special characteristics, these materials with special characteristics are in contact with the filter for a long time, which will cause the filter to be blocked, worn or damaged, and during the crushing and filtering process, impurities and particulate matter in the special copper materials will gradually accumulate on the filter. Long-term friction will cause the filter aperture to become larger, affecting the filtering effect. In order to ensure the sealing, the existing filter is usually fixed inside the filtering mechanism, which is not convenient for replacement. The filter that has been used for a long time will need to be replaced due to blockage or wear. The filter replacement process is complicated and time-consuming, which will increase equipment downtime and reduce production efficiency.

[0007] Therefore, the present invention proposes a crushing and filtering mechanism for recycling special copper materials to make up for and improve the shortcomings of the prior art. Summary of the invention

[0024] 2. Through the coordinated use of the filter top frame and the fixing mechanism, the fixing state between the sliding push rod and the sliding cross bar is released, so that the sliding adjustment block can be pulled out from the inside of the device, so that the sliding adjustment block can be directly taken out by opening the device, so as to replace the sliding filter plate, thereby solving the problem that the sliding filter plate inside the device is not easy to replace. Timely replacement of the worn or clogged adjusting sliding bottom frame can ensure the filtering effect of the crushing and filtering mechanism. Maintaining good filtering performance is conducive to improving the quality of recycled special copper materials and reducing the impact of impurities on subsequent processes. The design of the easy replacement adjusting sliding bottom frame allows the selection of appropriate adjusting sliding bottom frame specifications and materials according to different recycling needs and material characteristics, so that the filtering accuracy and processing capacity can be flexibly adjusted to adapt to a variety of special copper recycling tasks.

[0025] 3. Through the coordinated use of the flipping mechanism and the fixing mechanism, the flipping mechanism is used to control the fixing state of the fixing mechanism of the sliding filter plate. The sliding filter plate can be flipped to a fixed position through the flipping mechanism, and the fixing of the sliding filter plate can be released only when it reaches the fixed position, thereby reducing the chance of operators contacting the filter screen and reducing the risk of accidental injury. The sliding filter plate can be quickly flipped to a fixed position through the flipping mechanism, thereby reducing the time for operators to adjust the position of the sliding filter plate and improving operating efficiency.

[0040] refer to Figures 1 to 9 A crushing and filtering mechanism for recycling special copper materials according to a preferred embodiment of the present invention will be described in detail below. A crushing and filtering mechanism for recycling special copper materials includes a bracket 1, a filter top frame 2 is fixedly connected to the top of the bracket 1, a flip mechanism 3 for cleaning the filter screen surface is arranged inside the filter top frame 2, and a fixing mechanism 4 for facilitating filter screen replacement is arranged inside the filter top frame 2;

[0041] The flipping mechanism 3 includes an adjustable sliding bottom frame 312 for controlling the filter screen to flip in the opposite direction;

[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, and an adjusting sliding bottom frame 312 is slidably connected to the inside of the filter top frame 2. The surface of the adjusting sliding bottom frame 312 is fixedly connected to the adjusting sliding top frame 313, and the adjusting sliding top frame 313 is L-shaped. The interior of the sliding adjustment block 311 is rotatably connected to a central rotating shaft 318, and one end of the central rotating shaft 318 close to the adjusting sliding bottom frame 312 is fixedly connected to a sliding cross bar 314, and the surface of the sliding cross bar 314 is fixedly connected to a rotating lever 315, and the rotating lever 315 is an inverted L-shape.

The lateral part of the adjusting sliding bottom frame 312 is located in the sliding path of the dial circular shaft 316, and the limit fixed shaft 3110 is located on the rotating path of the outer sleeve rod 319. A rotating groove is opened inside the filtering top frame 2, and the height of the adjusting sliding bottom frame 312 is equal to the height of the rotating groove inside the filtering top frame 2. There are two lateral parts of the surface of the adjusting sliding bottom frame 312, and the two lateral parts of the surface of the adjusting sliding bottom frame 312 are symmetrically arranged with the sliding cross bar 314 as the axis.

[0044] The effects achieved by this embodiment are as follows: in the process of recycling special copper materials, the crushed materials will be filtered through a filter to remove impurities and larger particles. The crushed special copper materials may be sticky or finely divided, and are easy to adhere to the filter and gradually accumulate. As the filtering proceeds, impurities will gradually accumulate on the filter, causing the filter to be blocked. By turning over the sliding filter plate 412 inside the device and replacing the material receiving frame inside the device, the materials on the surface of the sliding filter plate 412 are centrally cleaned and collected by vibration, thereby solving the problem that the filter surface is easy to be blocked and difficult to clean. When one side of the sliding filter plate 412 is blocked by impurities, the sliding filter plate 412 is turned over and the surface of the sliding filter plate 412 is cleaned by vibration, thereby reducing the cleaning resistance and improving the 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 cross bar 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, the end of the sliding cross bar 314 away from the sliding adjustment block 311 is fixedly connected to the side block 413, the inside of the sliding cross bar 314 is slidably connected to the center cross bar 418, the surface of the sliding cross bar 314 is slidably connected to the outer push plate 417, the inside of the sliding cross bar 314 is slidably connected to the center cross bar 418, and the center cross bar The rod 418 is fixedly connected to the outer push plate 417, the sliding cross bar 314 is fixedly connected with a No. 2 spring 416 inside, the No. 2 spring 416 and the center cross bar 418 are fixedly connected, the sliding push rod 411 is slidably connected with a positioning block 415, the sliding push rod 411 is fixedly connected with a No. 1 spring 414, the No. 1 spring 414 and the positioning block 415 are fixedly connected, two positioning blocks 415 are arranged symmetrically with the No. 2 spring 416 as the axis, the side of the positioning block 415 away from the side block 413 is arranged as an inclined surface, and the side of the side block 413 away from the sliding adjustment block 311 is arranged as an inclined surface.

[0046] The effects achieved by this embodiment are as follows: during the crushing and filtering process, impurities and particulate matter in the special copper material will gradually accumulate on the filter screen. Long-term friction will cause the filter screen aperture to become larger, affecting the filtering effect. Since the existing filter screen is usually fixed inside the filtering mechanism to ensure sealing, it is not convenient to replace. The filter screen that has been used for a long time will need to be replaced due to blockage or wear. The filter screen replacement process is complicated and time-consuming, which will increase the equipment downtime and reduce production efficiency. The positioning 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 cross bar 314, so that the sliding adjustment block 311 is pulled out of the device, so that the sliding filter plate 412 can be directly taken out by opening the device, so as to replace the sliding filter plate 412, which solves the problem that the sliding filter plate 412 inside the device is not easy to replace. Timely replacement of the worn or blocked sliding filter plate 412 can ensure the filtering effect of the crushing and filtering mechanism, and maintaining good filtering performance is conducive to improving the quality of recovered special copper materials.

[0047] The following is the entire working process and working principle of the above embodiment:

[0048] Initially: an electric telescopic rod is arranged inside the filter top frame 2, the sliding adjustment block 311 is fixedly connected to the electric telescopic rod, the circular shaft 316 is moved to fit the surface of the veneer slider 317, the pulling spring 3113 is in an unstretched state, the positioning block 415 is located inside the limiting groove inside the sliding cross bar 314, the No. 2 spring 416 and the No. 1 spring 414 are both in an uncompressed state, the outer push plate 417 is located at the positioning block 415 close to one end of the side block 413, and the sliding cross bar 314 is located inside the sliding push rod 411.

[0049] During operation: when the crushed materials of the special copper material adhere to the filter screen and gradually accumulate, thereby clogging the filter screen, the device is opened to replace the material receiving frame inside the device. Since the sliding adjustment block 311 is fixedly connected to the electric telescopic rod, when the surface of the filter screen is cleaned, the electric telescopic rod pushes the sliding adjustment block 311 to slide upward, and the sliding adjustment block 311 slides upward and drives the rotating lever 315 to slide upward through the sliding cross bar 314. Since the lateral part of the adjusting sliding top frame 313 is located inside the sliding path of the toggle circular shaft 316, the sliding cross bar 314 slides upward, and the toggle circular shaft 316 contacts the lateral part of the adjusting sliding top frame 313, giving the toggle circular shaft 316 a thrust, thereby driving the rotating lever 315 The movable lever 315 rotates around the sliding cross bar 314 in the rotating groove inside the filter top frame 2. Since the sliding cross bar 314 is fixedly connected to the central rotating shaft 318, and the outer sleeve rod 319 is fixedly connected to the surface of the central rotating shaft 318, the sliding cross bar 314 rotates to drive the outer sleeve rod 319 to rotate through the central rotating shaft 318, and the second pull shaft 3114 is stretched under the pull of the second pull shaft 3114. When the rotation angle of the outer sleeve rod 319 exceeds ninety degrees, the outer sleeve rod 319 limits the rotation of the sliding cross bar 314 under the pull of the second pull shaft 3114, so that the sliding filter plate 412 on the surface of the sliding push rod 411 is turned over 180 degrees through the sliding cross bar 314;

[0050] When the sliding filter plate 412 is turned over, the sliding adjustment block 311 is driven by the electric telescopic rod to slide downward, the device is opened and the material receiving frame inside the filter top frame 2 is replaced, the blocked materials on the surface of the sliding filter plate 412 are shaken down by the vibration of the device when working, and are collected centrally by the new material receiving frame, and the sliding filter plate 412 inside the device is turned over, and the materials on the surface of the sliding filter plate 412 are cleaned by vibration, thereby solving the problem that the filter surface is easy to be blocked and difficult to clean. When one side of the sliding filter plate 412 is blocked by impurities, the sliding filter plate 412 is turned over by the turning mechanism 3, and the blocked materials on the surface of the sliding filter plate 412 are cleaned by vibration, and the blocked materials on the surface of the sliding filter plate 412 are collected centrally by the new material receiving frame, thereby reducing the cleaning resistance and improving the cleaning efficiency. Moreover, since the impurities are evenly distributed on both sides of the sliding filter plate 412 instead of being concentrated on one side, the turning mechanism 3 can reduce the local wear of the sliding filter plate 412, extend the service life of the sliding filter plate 412, and reduce the operating cost.

[0051] Furthermore, when materials with special characteristics come into contact with the filter screen for a long time, resulting in clogging, wear or damage to the filter screen, and the filter screen needs to be replaced, the sliding push rod 411 is manually pushed to slide in the direction of the adjusting sliding bottom frame 312. Since a positioning groove is provided inside the sliding cross bar 314, and the positioning block 415 is located in the positioning groove inside the sliding cross bar 314, and the sliding push rod 411 fixes the sliding filter plate 412, when the sliding filter plate 412 is replaced, the sliding push rod 411 is manually pushed to slide in the direction of the adjusting sliding bottom frame 312. The bottom frame 312 slides in the direction of the bottom frame 312. Since the side of the positioning block 415 close to the adjustment sliding bottom frame 312 is set as an inclined surface, the sliding push rod 411 slides in the direction of the adjustment sliding bottom frame 312, and the inclined surface of the positioning block 415 fits with the surface limiting groove of the sliding cross bar 314, thereby giving the positioning block 415 an upward force, thereby pushing the positioning block 415 to slide in the direction of the No. 1 spring 414, and the No. 1 spring 414 is compressed under the push of the positioning block 415. When the outer push plate 417 contacts the positioning block 415, the positioning block 415 is pushed on the outer push plate 4 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 the No. 1 spring 414. When the sliding push rod 411 is pushed away from the sliding cross bar 314 by manual pushing, the locking block 415 contacts the outer push plate 417, and the outer push plate 417 is pushed to slide toward the side block 413 by the locking block 415. The second spring 416 is compressed by the central cross bar 418. As the outer push plate 417 slides toward the side block 413 under the push of the positioning block 415 and blocks the internal limiting groove of the sliding cross bar 314, when the side block 413 fits the outer push plate 417, the positioning 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 cross bar 314, so that the sliding adjustment block 311 is pulled out of the device.

[0052] Therefore, the sliding filter plate 412 can be directly taken out by opening the device, so that the sliding filter plate 412 can be replaced, which solves the problem that the sliding filter plate 412 inside the device is difficult to replace. Timely replacement of the worn or clogged adjusting sliding bottom frame 312 can ensure the filtering effect of the crushing and filtering mechanism. Maintaining good filtering performance is conducive to improving the quality of recycled special copper materials and reducing the impact of impurities on subsequent processes. The design of the easy-to-replace adjusting sliding bottom frame 312 allows the selection of appropriate specifications and materials of the adjusting sliding bottom frame 312 according to different recycling needs and material characteristics, so that the filtering accuracy and processing capacity can be flexibly adjusted to adapt to a variety of special copper recycling tasks.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
