Description

Technical Field

[0001] This invention relates to the field of metal resource recycling technology, specifically to a waste recycling and processing equipment and method for metal product manufacturing and processing. Background Technology

[0002] Metal products refer to various products made from metal materials (such as iron, steel, aluminum, copper, zinc, stainless steel, etc.) as the main raw materials through processes such as casting, forging, stamping, cutting, welding, and machining. Metal products are scrapped due to wear, corrosion (such as rust), and fatigue. Therefore, it is unavoidable that metal products generate waste during production and use when recycling scrap metal. When dealing with oxide scale and rust generated from metal product waste, the appropriate method should be selected according to the subsequent use (such as recycling, reuse or environmental disposal). A common method is mechanical peeling, which uses physical friction from brushes or abrasives to directly break the bond between the oxide layer and the substrate. This method is especially suitable for loose oxide scale or surface rust.

[0003] The prior art discloses Chinese Patent Application No. CN202310586643.8, a construction pipe waste collection device and its usage method, which discloses that four X-shaped folding frames abut against the side of the pipe, a bidirectional motor drives the drive gear to rotate clockwise, and drives the fixed grinding block and two sliding grinding blocks to rub and remove rust on the outside of the square pipe, reducing the rust on the surface of the square pipe. When the second spring telescopic rod pushes the hinge of the V-shaped hinge plate to move to the outside of the square pipe, it generates an impact force on the surface of the pipe, which makes it easier to shake off the impurities remaining on the inner wall of the pipe, increasing the quality of pipe recycling for users.

[0004] Although the above-mentioned device can perform rust removal on recycled waste materials, it still has some shortcomings in use: 1. The above-mentioned device can only remove external rust from workpieces of a specific shape (rectangular), and can only be operated in a single operation when removing rust from rectangular parts, which makes it difficult to recycle and remove rust in batches. 2. When the existing equipment removes scale and rust from the waste materials produced in batches of metal products, it is difficult to clean the surface of the waste materials that are pushed together due to the wide variety of metal products. As a result, the scale and rust on the surface of the metal waste cannot be removed effectively. Furthermore, when removing rust, the rust that falls off will stick back to the metal waste. Summary of the Invention

[0005] The purpose of this invention is to provide a waste recycling and processing equipment and method for metal product manufacturing and processing, so as to solve the problem of removing oxide scale and rust from batches of irregular metal product waste mentioned in the background art.

[0006] The objective of this invention can be achieved through the following technical solutions: A waste recycling and processing equipment for metal product manufacturing includes a processing tank, with support frames on both sides for sliding support, a central rod rotatably mounted in the middle of the processing tank, drive units on both sides of the processing tank connected to the support frames, the drive units facilitating the driving and stirring of the metal waste in the processing tank, a disassembly assembly at the bottom of the processing tank for discharging small impurities during the processing of the metal waste, discharge units on both sides of the processing tank for discharging the processed metal waste, an opening at the top of the processing tank penetrating the processing tank, and multiple friction blocks on the inner wall of the processing tank.

[0007] Preferably, when the drive unit is turned on, the shaking unit can also make the metal waste shake left and right in the processing barrel. The drive unit is also provided with a blowing component that communicates with the inner cavity of the processing barrel on one side, and a combing unit located in the inner cavity of the processing barrel is also provided on the central rod.

[0008] Preferably, the drive unit includes sleeves fitted at both ends of the central rod, with circumferentially arranged guide grooves inside the sleeves, and rectangular bars fixed to the central rod slidably installed in the guide grooves. Shafts are fixed at the ends of the sleeves on both sides, with gears installed on the shafts. The gears mesh with racks below, and the two racks are connected by a timing frame. A cylinder is installed between the timing frame and a support frame on one side.

[0009] Preferably, the shaking unit includes an arc plate fixed to the rack, a connecting plate fixed to the processing tank on one side of the arc plate, a roller rotatably mounted on the side of the connecting plate near the arc plate, a bent plate connected to the support frame on one side of the processing tank, a slide rod slidably mounted on the bent plate, a stabilizing frame connected to the processing tank fixedly mounted on one side of the slide rod, and a spring sleeved on the outside of the slide rod.

[0010] Preferably, the blowing assembly includes a fixed frame, which is fixedly connected to the side of the processing tank. An air cylinder is fixedly installed in the middle of the fixed frame, and a piston rod is slidably installed in the middle of the air cylinder. A connecting block fixedly connected to the support frame is provided on one side of the piston rod. An arc-shaped tube is fixedly installed on one side of the air cylinder, and multiple vertical tubes are provided on the arc-shaped tube, which are connected to the processing tank.

[0011] Preferably, the disassembly assembly includes a discharge pipe located at the bottom of the processing tank. The discharge pipe is rectangular and hollow. Movable grooves are opened on both sides of the inner wall of the discharge pipe. A filter plate is slidably installed in the movable groove. A spring fixed to the filter plate is provided in the movable groove. A vibration rod is fixedly installed in the middle of the lower end face of the filter plate. A bottom frame is detachably installed at the lower part of the discharge pipe. Round rods are fixedly installed on both sides of the processing tank. A locking plate for locking and fixing the bottom frame is slidably installed on the round rods.

[0012] Preferably, the discharge unit includes a cleaning box located outside the opening on one side, a push rod slidably mounted on the cleaning box, a spring sleeved on the outside of the push rod, and a push plate fixedly mounted at the end of the push rod. A discharge box is fixedly mounted on the side of the opening away from the cleaning box, and a discharge door is hinged to one side of the discharge box via a hinge. An arc-shaped groove is opened on the top of the discharge box, and a discharge plate is slidably mounted in the arc-shaped groove.

[0013] Preferably, the combing unit includes multiple I-shaped frames arranged circumferentially on a central rod, multiple steel brushes arranged on both sides of the I-shaped frames, perforated plates sleeved on the outside of the steel brushes on both sides of the I-shaped frames, ear plates fixedly installed on both sides of the I-shaped frames, and an internal rod fixed to the perforated plate slidably installed in the middle of the ear plate.

[0014] Preferably, rotating rings are installed on both sides of the central rod via electric sliders. Multiple circumferentially arranged push-pull plates are hinged to the outside of the rotating rings. A control plate that slides with the I-beam is hinged to the side of the push-pull plate away from the rotating ring. Symmetrical control slots are opened on both sides of the control plate. The side of the internal rod away from the hole plate is placed in the control slot.

[0015] Another object of the present invention is to provide a method for processing waste materials from metal product manufacturing and processing equipment, comprising the following steps: S1: Waste Disposal: Waste materials used in metal processing are dumped through the door at the top of the processing bin, and then the door is closed. S2 waste disposal: The drive unit is activated to stir the oxidized and rusted metal waste in the processing barrel with the central rod, which strengthens the contact force between the metal waste and the friction block, thereby removing the oxide scale and rust from the surface of the waste. S3: Impurity Removal After processing, the oxide scale and rust on the exterior of the metal scrap fall to the bottom of the processing tank. By disassembling the components, the impurities can be quickly cleaned up.

[0016] The beneficial effects of this invention are: 1. This invention uses a drive unit to move the central rod in a circumferential stirring motion and the processing tank to sway left and right, achieving multi-directional and full contact between the metal waste and the friction blocks, eliminating static pushing dead angles. The dual motion mode, with stirring and shaking, significantly enhances friction intensity, promoting the rapid removal of scale and rust. At the same time, the collision between waste materials further accelerates surface cleaning efficiency. The disassembly component design enables the separation and collection of scale and rust from the metal waste, facilitating centralized processing of detached impurities and preventing impurities from adhering to the surface of the cleaned waste, ensuring the durability of the treatment effect. The discharge unit discharges materials sequentially to the separated processing spaces, completely solving the problem of waste residue in traditional devices, ensuring no accumulation in the processing tank, and improving the continuity and integrity of batch processing.

[0017] 2. This invention accelerates the impact between metal scraps by sliding the processing barrel left and right, effectively removing oxide scale and rust. At the same time, the linkage blower component automatically blows air into the barrel, which not only enhances the rust removal effect but also achieves real-time cooling to avoid heat accumulation. The mechanical energy of the moving processing barrel directly drives the blower component, requiring no additional energy, reducing energy consumption, and improving system energy efficiency. The blowing not only promotes the separation of rust chips and carries away loose rust through airflow but also assists in heat dissipation, optimizing processing efficiency and equipment durability.

[0018] 3. This invention uses a cylinder-driven rack and gear transmission system in conjunction with a rotating combing component to achieve forced mixing of metal waste, causing the waste to collide with the friction blocks on the barrel wall and with each other, physically removing oxide scale and rust. The efficiency is far higher than static pickling or manual treatment. The extension and retraction of the cylinder is converted into the forward and reverse rotation of the gears through the synchronous frame, driving the sleeve to rotate in both directions, avoiding the accumulation of waste caused by unidirectional movement and improving the uniformity of mixing.

[0019] 4. This invention powerfully removes rust, scale, and loose contaminants from waste materials through the dual action of friction and impact from the steel brush. It is especially suitable for waste materials with complex shapes or uneven surfaces, leaving no dead corners in the cleaning process. Combined with the left-right shaking of the vibration unit, it enhances the dynamic impact between the steel brush and the waste material, achieving a more thorough surface cleaning. The symmetrically designed perforated plates on the frame can be driven away from each other through the control slot, automatically straightening deformed brush rods and removing attached impurities, reducing the frequency of manual maintenance and extending the service life of the steel brush. The high rigidity design of the steel brush provides stronger force, making it more efficient at treating stubborn oxide layers compared to traditional flexible brushes or chemical treatments, and eliminating the risk of chemical pollution.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0023] As attached Figure 1-10As shown, a waste recycling and processing equipment for metal product manufacturing includes a processing tank 1, with support frames 10 on both sides of the processing tank 1 for sliding support, a central rod 12 rotatably mounted in the middle of the processing tank 1, drive units connected to the support frames 10 on both sides of the processing tank 1 for driving and stirring the metal waste in the processing tank 1, a disassembly assembly for discharging small impurities during the processing of the metal waste at the bottom of the processing tank 1, discharge units for discharging the processed metal waste on both sides of the processing tank 1, an opening 15 penetrating the processing tank 1 at the top of the processing tank 1, and multiple friction blocks 11 on the inner wall of the processing tank 1. The drive unit activates the central rod 12 to agitate the metal scrap in the processing tank 1 in a circumferential manner. On one hand, the friction between the multiple metal scrap pieces and the friction blocks 11 within the processing tank 1 is enhanced, preventing dead zones caused by static pushing and ensuring that all surfaces of the scrap are uniformly treated. This accelerates the removal of oxide scale and rust from the metal scrap. On the other hand, while the drive unit agitates the central rod 12, the shaking unit also causes the processing tank 1 to sway left and right. This causes the metal waste in the processing bucket 1 to shake left and right, resulting in more collisions and further accelerating the peeling speed of the oxide scale and rust on the outside of the metal waste. Compared with the existing device, the present invention can remove the oxide scale and rust on the outside of the metal waste by stirring after the metal waste is pushed, so that the metal waste and the friction block 11 can be fully rubbed, and the processing bucket 1 can also cause the metal waste to shake left and right. At this time, the metal waste will collide inside the processing bucket 1, thereby further promoting the peeling of the oxide scale and rust on the outside of the metal waste. By setting up the disassembly components, the oxide scale and rust on the outside of the metal scrap can be cleaned and collected. After the outside of the metal scrap is treated, on the one hand, the fallen oxide scale and rust are collected in a concentrated manner, and on the other hand, by collecting the oxide scale and rust separately from the metal scrap, the oxide scale and rust can be prevented from sticking to the surface of the metal scrap again. By setting up the discharge unit, the processed metal waste can be discharged sequentially from the processing spaces of multiple metal wastes separated in the processing bucket 1, effectively avoiding the residue of metal waste in the processing bucket 1 due to incomplete discharge after processing.

[0024] When the drive unit is turned on, the metal waste can be shaken left and right in the processing bucket 1 by the setting of the shaking unit. The drive unit is also equipped with a blowing component that communicates with the inner cavity of the processing bucket 1 on one side. The center rod 12 is also equipped with a combing unit located in the inner cavity of the processing bucket 1. The drive unit drives the shaking unit to move the processing barrel 1 left and right on the support frame 10. At the same time, the blowing component can be activated when the processing barrel 1 moves, so when the processing barrel 1 moves to accelerate the impact of the metal scrap, the blowing component can also blow air into the processing barrel 1. By blowing air into the processing barrel 1, the rust on the outside of the metal scrap can be blown off. On the other hand, the heat generated inside the processing barrel 1 during the processing of the metal scrap can be cooled down. Compared with the existing device, the present invention can use the processing barrel 1 to slide left and right on the support frame 10 to accelerate the removal of oxide scale and rust on the outside of the metal scrap inside the processing barrel 1, while simultaneously driving the blowing component to blow air into the processing barrel 1, accelerating the removal of rust and cooling down the inside of the processing barrel 1.

[0025] The drive unit includes sleeves 13 fitted at both ends of the central rod 12. A circumferentially arranged guide groove 131 is provided in the sleeve 13. A rectangular strip 121 fixed to the central rod 12 is slidably installed in the guide groove 131. A shaft 132 is fixed at the far end of each sleeve 13. A gear 133 is installed on the shaft 132. The gear 133 meshes with a rack 32 below. The two racks 32 are connected by a timing frame 31. A cylinder 3 is installed between the timing frame 31 and the support frame 10 on one side. When the drive unit is activated to remove scale and rust from the metal waste in the processing tank 1, cylinder 3 is activated to extend and retract. When cylinder 3 pushes forward, it moves the timing frame 31 and rack 32 toward one side of the processing tank 1. At this time, rack 32 drives gear 133 to rotate clockwise. Conversely, when cylinder 3 retracts, timing frame 31 and rack 32 move away from the processing tank 1. At this time, gear 133 rotates counterclockwise. When gear 133 rotates, it drives sleeve 13 through shaft 132. As the sleeve 13 rotates, the central rod 12 rotates synchronously with the sleeve 13 because the multiple rectangular bars 121 are located in the multiple guide grooves 131. When the central rod 12 rotates, it can drive the combing assembly to stir the metal waste stored in the processing bucket 1. When the waste is stirred, it comes into uniform contact with the friction blocks 11 distributed on the inner wall of the processing bucket 1. At the same time, the waste can also collide with each other, accelerating the peeling and shedding of the oxide scale and rust on the outside of the metal waste from the metal waste.

[0026] The shaking unit includes an arc plate 55 fixed to the rack 32. A connecting plate 53 fixed to the processing tank 1 is provided on one side of the arc plate 55. A roller 54 is rotatably installed on the side of the connecting plate 53 near the arc plate 55. A bent plate 5 connected to the support frame 10 is provided on one side of the processing tank 1. A slide rod 51 is slidably installed on the bent plate 5. A stabilizing frame 52 connected to the processing tank 1 is fixedly installed on one side of the slide rod 51. A spring is sleeved on the outside of the slide rod 51. When the drive unit is activated, the rack 32 moves to stir the metal waste in the processing tank 1. Simultaneously, because one side of the rack 32 has an arc plate 55, the movement of the rack 32 also drives the arc plate 55 to move. As the arc plate 55 moves, it intermittently squeezes the roller 54. After being squeezed, the roller 54 moves the connecting plate 53, thus pushing the processing tank 1 away from the arc plate 55. At this time, the stabilizing frame 52 moves with the processing tank 1, causing the sliding rod 51 to slide. The stabilizing frame 52 and the sliding rod 51 compress the spring as they move. When the rack 32 moves the arc plate 55 to release the pressure on the roller 54 and the connecting plate 53, the spring pushes the stabilizing frame 52, causing it and the processing tank 1 to reset. When the drive unit is activated, the center rod 12 rotates to stir the metal waste in the processing tank 1. Simultaneously, with the vibration unit, the metal waste in the processing tank 1 is shaken left and right, further enhancing the removal efficiency of the external oxide scale and rust on the metal waste.

[0027] The blowing assembly includes a fixed frame 4, which is fixedly connected to the side of the processing tank 1. An air cylinder 41 is fixedly installed in the middle of the fixed frame 4. A piston rod 45 is slidably installed in the middle of the air cylinder 41. A connecting block 44 fixedly connected to the support frame 10 is provided on one side of the piston rod 45. An arc-shaped tube 42 is fixedly installed on one side of the air cylinder 41. Multiple vertical tubes 43 are provided on the arc-shaped tube 42, which are equidistantly distributed and communicate with the processing tank 1. When the shaking unit drives the processing barrel 1 to reciprocate on the support frame 10, the fixed frame 4 synchronously drives the air cylinder 41 to move with the processing barrel 1. Since the connecting block 44 is fixed to the support frame 10, when the air cylinder 41 moves toward the connecting block 44, the piston rod 45 compresses the gas in the air cylinder 41. The air pressure in the air cylinder 41 is transmitted to multiple vertical pipes 43 through the arc-shaped pipe 42. The multiple vertical pipes 43 are connected to multiple spaces separated by the combing unit in the processing barrel 1, so that when the gas in the air cylinder 41 is compressed, the multiple vertical pipes 43 blow air into the working space in the multiple processing barrels 1. When the air cylinder 41 moves away from the connecting block 44, the hot air in the processing barrel 1 will be discharged through the exhaust port on the side of the air cylinder 41. By blowing air into the processing barrel 1, the temperature inside the processing barrel 1 is cooled and dissipated. On the other hand, by blowing air onto the surface of the waste, the speed at which the oxide scale and rust fall off the metal waste can be accelerated.

[0028] The disassembly assembly includes a discharge pipe 14 located at the bottom of the processing tank 1. The discharge pipe 14 is rectangular and hollow. Movable grooves 141 are opened on both sides of the inner wall of the discharge pipe 14. A filter plate 142 is slidably installed in the movable grooves 141. A spring is provided in the movable grooves 141 to fix the filter plate 142. A vibration rod 143 is fixedly installed in the middle of the lower end face of the filter plate 142. A bottom frame 147 is detachably installed at the lower part of the discharge pipe 14. Round rods 145 are fixedly installed on both sides of the processing tank 1. A locking plate 146 for locking the bottom frame 147 is slidably installed on the round rods 145. The filter plate 142 is designed to remove scale and rust from waste materials during external removal. The scale and rust pass through the filter plate 142 and eventually fall into the bottom frame 147. When the scale and rust that fall off during the external treatment of waste materials used in metal product manufacturing are dumped, the sliding plate 146 on the round rod 145 moves the two side plates 146 away from each other, releasing the jamming on the bottom frame 147. The bottom frame 147 is then manually released, allowing the scale and rust impurities inside to be dumped. After the bottom frame 147 is released, the support for the vibrating rod 143 is removed, and the filter plate 142 moves down in the moving groove 141. When the bottom frame 147... When 47 is reinstalled on the feed pipe 14, the bottom frame 147 moves upward and pushes the vibrating rod 143. At this time, the vibrating rod 143 simultaneously drives the filter plate 142 to move upward and reset. When the filter plate 142 is pushed upward by the vibrating rod 143, the vibrating rod 143 can also knock and vibrate the filter plate 142, thereby clearing the oxide scale and rust blocking the filter plate 142. Compared with the existing device, the present invention can dump the oxide scale and rust impurities generated during the external processing of metal waste without affecting the external processing of metal waste. It can complete the separation of metal waste and impurities without separately processing the oxide scale and rust impurities in the metal waste.

[0029] The discharge unit includes a cleaning box 16 located outside the opening 15 on one side. A push rod 161 is slidably mounted on the cleaning box 16. A spring is sleeved on the outside of the push rod 161. A push plate 162 is fixedly mounted at the end of the push rod 161. A discharge box 17 is fixedly mounted on the side of the opening 15 away from the cleaning box 16. A discharge door 171 is hinged to one side of the discharge box 17 via a hinge. An arc-shaped groove 172 is opened on the top of the discharge box 17. A discharge plate 173 is slidably mounted in the arc-shaped groove 172. By manually pushing the push rod 161, the push rod 161 drives the push plate 162 to move, thereby moving the waste material that has undergone external oxide scale and rust treatment to the discharge box 17. After opening the discharge door 171, the discharge plate 173 in the sliding arc groove 172 can discharge the waste material.

[0030] The combing unit includes multiple I-shaped frames 6 arranged circumferentially on the central rod 12, multiple steel brushes 62 arranged on both sides of the I-shaped frame 6, perforated plates 61 sleeved on both sides of the I-shaped frame 6 and ear plates 63 fixedly installed on both sides of the I-shaped frame 6, and an internal rod 68 fixed to the perforated plate 61 is slidably installed in the middle of the ear plate 63. By using the steel brush 62 to generate friction and impact on the surface of the waste, rust, scale, and loose contaminants attached to the surface of the metal waste can be effectively scraped off. It can effectively handle waste with complex shapes or uneven surfaces. Furthermore, the steel brush 62, following the stirring of the central rod 12, can ensure full contact between the steel brush 62 and all surfaces of the waste, avoiding dead corners and improving overall cleaning efficiency. At the same time, the rigidity of the steel brush 62 can make more powerful contact with the outside of the waste. While stirring the waste, the steel brush 62 can also perform a comprehensive cleaning operation when the waste is shaken left and right by the shaking unit and impacts the steel brush 62. Compared with existing devices, the steel brush 62 used in this invention can effectively treat the outside of the waste and powerfully remove scale and rust from the outside of the waste.

[0031] A rotating ring 64 is mounted on both sides of the central rod 12 via an electric slider. Multiple circumferentially arranged push-pull plates 65 are hinged to the outside of the rotating ring 64. A control plate 66 that slides with the I-frame 6 is hinged to the side of the push-pull plate 65 away from the rotating ring 64. Symmetrical control slots 67 are opened on both sides of the control plate 66. The side of the built-in rod 68 away from the perforated plate 61 is placed in the control slot 67. When the built-in rod 68 slides outward on the ear plate 63, the perforated plates 61 on both sides of the I-frame 6 move away from each other. When the two perforated plates 61 on the I-frame 6 move away from each other, the perforated plates 61 can straighten the deformed brush rod of the steel brush 62 after a certain period of use, and can also clean the impurities on the steel brush 62. The electric slider opens and drives the rotating ring 64 to rotate. When the rotating ring 64 rotates, it simultaneously drives multiple push-pull plates 65 to rotate. When the push-pull plates 65 rotate, they push multiple control plates 66. At this time, the control slots 67 on the control plates 66 cause both sides to move.

[0032] Another object of the present invention is to provide a method for processing waste materials from metal product manufacturing and processing equipment, comprising the following steps: S1: Waste Disposal: Waste materials used in metal processing are dumped through the door at the top of processing bin 1, and then the door is closed. S2 waste disposal: The drive unit is turned on to make the center rod 12 stir the oxidized and rusted metal waste in the processing barrel 1, and strengthen the contact force between the metal waste and the friction block 11, thereby removing the oxide scale and rust on the surface of the waste. S3: Impurity Removal After processing, the oxide scale and rust on the outside of the metal scrap fall to the bottom of the processing tank 1. By disassembling the components, the impurities can be quickly cleaned up.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
