Description

Technical Field

[0001] This invention relates to the field of copper scrap recycling technology, specifically to a drying and forming device for copper scrap recycling. Background Technology

[0002] The milling process of copper tubes continuously generates a large amount of copper shavings. These shavings have high recycling value and can be collected, processed, and recast to achieve resource recycling. During milling, cutting fluid is sprayed to cool and lubricate the tools and workpieces. As a result, the copper shavings contain a large amount of cutting fluid. If they are directly fed into the furnace, the high water content of the copper shavings will cause the water vapor to vaporize rapidly during smelting, leading to splashing in the furnace, generating a large amount of smoke, damaging the purity of the molten copper, reducing the quality of the finished copper tubes, and increasing smelting energy consumption and safety hazards.

[0003] The current industry standard for processing copper shavings is to use multi-stage conveyors to collect the shavings produced by the milling machine into a silo, then transfer them to an independent spin dryer to remove the cutting fluid. The dried shavings are then fed into an extrusion machine to be pressed into blocks. These blocks are easier to transport, stack, and remelt. However, existing complete processing equipment still has many shortcomings: First, traditional equipment lacks an integrated and coordinated layout. The copper shavings collection, drying, and extrusion molding units operate independently. During the transfer process, copper shavings are prone to scattering and cutting fluid is prone to leaking, polluting the workshop environment. In addition, the material conveying continuity is poor and the production efficiency is low. Secondly, the extrusion molding equipment relies on a single pushing structure for material discharge. During the pushing process, residual fine copper shavings are easily adhered to the inner wall of the conveyor cylinder. Long-term accumulation will block the channel and affect the normal discharge of block copper shavings. Manual cleaning is difficult and downtime is long. In summary, existing copper scrap recycling equipment suffers from problems such as easy leakage during material transfer, difficulty in cleaning copper accumulation on the inner wall of the extrusion cylinder, easy rolling off of the formed copper blocks during transport, poor linkage between processes, and inability to achieve continuous and stable automated production. These issues make it difficult to meet the needs of high-efficiency recycling of large quantities of copper scrap in copper tube milling production lines. Therefore, we propose a drying and forming device for copper scrap recycling. Summary of the Invention

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.

[0019] Example 1

[0020] Please see Figures 1-9 The figure shows a drying and molding device for copper scrap recycling, including an extrusion molding box 101 and a screw conveyor 102 for conveying copper scrap. The extrusion molding box 101 is provided with a mold component 103 for assisting in extruding copper scrap into blocks, and a conveyor plate 104 for conveying the copper scrap after molding is provided on the extrusion molding box 101. It should be noted here that: through transmission, the screw conveyor 102 evenly pushes the dry and loose copper shavings into the mold component 103 inside the extrusion molding box 101. After the dry copper shavings fill the cavity inside the mold component 103, the hydraulic pressure mechanism of the extrusion molding box 101 is activated to apply high pressure to the loose copper shavings in the cavity. Under the pressure, the copper shavings undergo plastic deformation, and the copper shaving particles interlock and interlock tightly to form a dense and non-loose block copper billet. In addition, the screw conveyor 102 and the mold component 103 are conventional components in this application, and their working principle, structural composition and control method will not be described in detail here. Also includes: The feeding assembly is used to feed and convey the processed copper chips. A spin-drying assembly for separating the cutting fluid from the copper chips is provided between the feeding assembly and the screw conveyor 102. The discharge component is located inside the extrusion molding box 101 and is used to assist in the discharge of the extruded copper chips. The extrusion molding box 101 is equipped with a push component for assisting in the discharge and a cleaning component for assisting in the cleaning process during the push. The copper chips are conveyed toward the conveyor plate 104 under the pushing action of the push component. And, a limiting component provided on the conveyor plate 104 for limiting the movement of the pushed blocky copper chips; It should be noted that the integrated feeding, drying, and extrusion molding processes are carried out in a coordinated manner. The closed conveying system prevents leakage and contamination of copper shavings and cutting fluid. The copper shavings have a low moisture content after drying, eliminating the safety and quality risks associated with remelting. During the feeding process, the cleaning brush 702 is driven to clean the inner wall of the conveyor cylinder 401. Combined with the separation tank 403, the broken copper is screened, reducing downtime for cleaning and improving raw material utilization. The elastic limit component of the conveyor plate 104 buffers the copper blocks and prevents them from rolling back. The entire set of equipment operates in a fully automatic cycle. The formed copper billets are dense and easy to transport, which greatly improves the efficiency of copper shavings recycling and reduces production and maintenance costs.

[0021] Preferably, the feeding assembly includes a first conveyor 202 and a storage bin 201. One end of the first conveyor 202 is connected to the copper chip outlet of the milling machine, and the other end of the first conveyor 202 is located above the storage bin 201. It should be noted here that the copper tube milling machine produces wet copper chips mixed with a large amount of cutting fluid during the cutting process. These chips fall directly into the feed end of the first conveyor 202. The first conveyor 202 continuously conveys the copper chips upwards, and the chips fall into the storage bin 201 for centralized temporary storage. In addition, the working principle and control method of the first conveyor 202 are common technologies and will not be described in detail here.

[0022] Preferably, the spin-drying assembly includes a mounting frame 301, on which a spin dryer 302 is provided for spin-drying and separating the cutting fluid from the copper chips. A second conveyor 303 for conveying copper chips is provided between the spin dryer 302 and the storage bin 201, and a third conveyor 304 for conveying copper chips is provided between the spin dryer 302 and the screw conveyor 102. It should be noted that: wet copper shavings are discharged from the bottom outlet of the storage box 201 and conveyed by the second conveyor 303 to the inside of the spin dryer 302 fixed on the mounting frame 301. The spin dryer 302 rotates at high speed and uses centrifugal force to separate and throw out the cutting fluid trapped in the gaps of the copper shavings, thus completing the drying and dehydration of the copper shavings. The dried copper shavings are discharged from the bottom of the spin dryer 302 and transferred to the screw conveyor 102 by the third conveyor 304. The screw conveyor 102 pushes the dried and loose copper shavings evenly into the mold component 103 inside the extrusion molding box 101. In addition, the working principle and control method of the second conveyor 303 and the spin dryer 302 are conventional feeding components and spin drying components, respectively. As well-known technologies, they will not be described in detail here.

[0023] Preferably, the discharge assembly includes a conveying cylinder 401 fixed inside the extrusion molding box 101, a discharge channel 402 for assisting discharge is provided between the conveying cylinder 401 and the mold component 103, and multiple sets of separation grooves 403 for separating excess copper chips from the block copper chips are provided on the conveying cylinder 401. It should be noted here that after the extrusion molding is completed, the cylinder 602 drives the moving plate 601 to move forward horizontally. The moving plate 601 simultaneously drives the push rod 501 and the extrusion plate 502 to slide forward along the inside of the conveying cylinder 401. During the sliding process, the extrusion plate 502 passes through the feeding channel 402 and pushes the block copper chips formed in the mold forward.

[0024] Preferably, the feeding assembly includes an extrusion disc 502 slidably connected inside the conveying cylinder 401 for extruding and conveying blocky copper shavings. A push rod 501 is fixed on the extrusion disc 502. A moving assembly for moving the push rod 501 is provided on the extrusion molding box 101. The moving assembly includes a moving plate 601 disposed inside the extrusion molding box 101. One end of the push rod 501 is fixed to the moving plate 601. A cylinder 602 for driving the moving plate 601 is installed on the extrusion molding box 101. It should be noted here that after the extrusion molding is completed, the cylinder 602 drives the moving plate 601 to move forward horizontally. The moving plate 601 simultaneously drives the push rod 501 and the extrusion plate 502 to slide forward along the inside of the conveying cylinder 401. During the sliding process, the extrusion plate 502 passes through the feeding channel 402 and pushes the block copper chips formed in the mold forward.

[0025] Preferably, the cleaning component includes a mounting sleeve 701, which is rotatably connected to the outside of the push rod 501 in a sleeved state. Multiple sets of cleaning brushes 702 for cleaning copper shavings remaining on the inner wall of the conveying cylinder 401 are fixed to the outside of the mounting sleeve 701. A rotating component for rotating the mounting sleeve 701 is provided between the mounting sleeve 701 and the conveying cylinder 401. The rotating component includes a fixing sleeve 801 fixed to one side of the mounting sleeve 701. The fixing sleeve 801, the push rod 501 and the mounting sleeve 701 are concentrically arranged. A spiral groove 802 is provided on the fixing sleeve 801. A transmission pin 803 is fixed inside the conveying cylinder 401. One end of the transmission pin 803 is slidably connected to the spiral groove 802. It should be noted that during the forward linear movement of push rod 501, the transmission pin 803 fixed on the inner wall of conveying cylinder 401 slides relative to each other in the spiral groove 802 of fixed sleeve 801. During the relative movement, the linear feed motion of push rod 501 is converted into the circumferential rotation of fixed sleeve 801 and mounting sleeve 701. Multiple sets of cleaning brushes 702 on the outer side of mounting sleeve 701 rotate synchronously to scrape the fine copper shavings adhering to and accumulating on the inner wall of conveying cylinder 401 in all directions. Multiple sets of separation grooves 403 are opened on the cylinder wall of conveying cylinder 401. The scattered copper shavings adhering to the surface of the copper block fall from the separation grooves 403 and are recycled during the pushing process. Only the whole block copper shavings are conveyed forward.

[0026] Preferably, the limiting component includes a U-shaped frame 901 fixed on the conveyor plate 104, a mounting plate 902 connected to the U-shaped frame 901 via a telescopic component, a limiting baffle 903 fixed on the mounting plate 902, and an inclined surface 904 for resisting the ejected blocky copper chips on one side of the limiting baffle 903. It should be noted that: the extrusion disc 502 pushes the block copper shavings out of the conveyor cylinder 401. The copper block slides onto the conveyor plate 104 on the outside of the extrusion molding box 101 and slides forward. During the sliding process, the front end of the copper block contacts the inclined surface 904 of the limiting baffle 903. The inclined surface 904 transmits the thrust, pushing the mounting plate 902 to move outward. During the movement, the T-shaped rod 1001 slides along the U-shaped frame 901 to compress the spring 1002. The spring 1002 generates buffer resistance in the opposite direction, offsetting the impact force of the copper block and slowing down the sliding speed of the copper block. After the copper block has slid past the limiting baffle 903, the limiting baffle 903 is reset by the elastic force of the spring 1002. The reset of the limiting baffle 903 limits and blocks the moved copper block, preventing it from flowing back into the conveyor cylinder 401 and causing obstruction of the discharge.

[0027] Preferably, the telescopic assembly includes multiple sets of T-shaped rods 1001 slidably connected to the U-shaped frame 901, one end of the T-shaped rod 1001 is fixed to the mounting plate 902, and a spring 1002 is sleeved on the outside of the T-shaped rod 1001; It should be noted here that: multiple sets of T-shaped rods 1001 guide the movement of the mounting plate 902 after it is subjected to force, and together with the spring 1002, they facilitate the reset of the mounting plate 902 after movement.

[0028] In this solution: a drying and forming device for copper scrap recycling includes the following steps: The copper tube milling machine produces wet copper chips mixed with a large amount of cutting fluid during cutting. These chips fall directly into the feed end of the first conveyor 202, which continuously conveys them upwards. The chips then fall into a storage bin 201 for temporary storage. The wet copper chips are discharged from the bottom outlet of the storage bin 201 and transported by the second conveyor 303 to a centrifuge 302 fixed on the mounting frame 301. The centrifuge 302 rotates at high speed, using centrifugal force to separate and remove the cutting fluid trapped in the gaps of the copper chips, thus completing the drying and dehydration of the copper chips. The material exits from the bottom of the dryer 302 and is transferred to the screw conveyor 102 via the third conveyor 304. The screw conveyor 102 evenly pushes the dry and loose copper shavings into the mold component 103 inside the extrusion molding box 101. After the dry copper shavings fill the cavity inside the mold component 103, the hydraulic pressing mechanism of the extrusion molding box 101 is activated to apply high pressure to the loose copper shavings in the cavity. Under the pressure, the copper shavings undergo plastic deformation, and the copper shaving particles interlock and interlock tightly to form a dense and non-loose block copper billet. After extrusion molding is completed, cylinder 602 drives moving plate 601 to move forward horizontally. Moving plate 601 synchronously drives push rod 501 and extrusion plate 502 to slide forward along the inside of conveying cylinder 401. During the sliding process, extrusion plate 502 passes through feeding channel 402 and pushes the block copper chips formed in the mold forward. During the forward linear movement of push rod 501, transmission pin 803 fixed on the inner wall of conveying cylinder 401 slides relative to each other in spiral groove 802 of fixed sleeve 801. During the relative movement, the linear feed motion of push rod 501 is converted into circumferential rotation of fixed sleeve 801 and mounting sleeve 701. Multiple sets of cleaning brushes 702 on the outside of mounting sleeve 701 rotate synchronously to scrape the fine copper chips adhering to and accumulating on the inner wall of conveying cylinder 401 in all directions. Multiple sets of separation grooves 403 are opened on the cylinder wall of conveying cylinder 401. Scattered copper chips attached to the surface of copper block fall from the separation grooves 403 and are recycled during the pushing process. Only the complete block copper chips are conveyed forward. The extrusion disc 502 pushes the block copper shavings out of the conveyor cylinder 401. The copper block slides onto the conveyor plate 104 on the outside of the extrusion molding box 101 and slides forward. During the sliding process, the front end of the copper block contacts the inclined surface 904 of the limiting baffle 903. The inclined surface 904 transmits the thrust, pushing the mounting plate 902 to move outward. During the movement, the T-shaped rod 1001 slides along the U-shaped frame 901 to compress the spring 1002. The spring 1002 generates buffer resistance in the opposite direction, offsetting the impact force of the copper block and slowing down the sliding speed of the copper block. After the copper block slides under the limiting baffle 903, the limiting baffle 903 is reset by the elastic force of the spring 1002. The reset of the limiting baffle 903 limits and blocks the moved copper block, preventing it from flowing back into the conveyor cylinder 401 and causing the discharge to be obstructed. After a single feeding, cleaning, and conveying process is completed, the cylinder 602 drives the moving plate 601, push rod 501, and extrusion plate 502 to retract and reset. During the retraction process, the transmission pin 803 slides in the opposite direction along the spiral groove 802, and the cleaning brush 702 rotates in the opposite direction to perform secondary cleaning on the inner wall of the conveying cylinder 401. After resetting, the entire device returns to the standby feeding state and continuously repeats the entire process of feeding, drying, extrusion, pushing, cleaning, and limiting conveying, realizing fully automatic continuous drying, forming, and recycling of copper scraps.
