Description

Technical Field

[0001] The invention relates to the technical field of metal waste recycling, in particular to a metal waste recycling device. Background Art

[0002] Metal scrap refers to metal materials that no longer have economic value or cannot be reused in the production process. These metal scraps may come from the processing of manufacturing, construction, automobile dismantling and other scrap metal products. There are many types of scrap metal. By recycling and reusing metal scrap, we can reduce dependence on natural resources, reduce energy consumption and emissions, reduce the environmental impact of producing new metals, and also help save costs.

[0003] In the existing manufacturing industry, when recycling waste materials such as copper foil or aluminum chips generated by other processing methods such as turning, drilling or cutting, the above-mentioned types of waste are usually curled. When stacked in the transfer vehicle, the waste is very fluffy and the gaps between individual wastes are large, resulting in a low single stacking volume in the transfer vehicle and the inability to efficiently utilize the storage space in the transfer vehicle. Secondly, this type of metal waste is usually attached with powder particles generated by processing. In the subsequent recycling process, the powder particles will float around at will, which not only pollutes the on-site environment but also affects the health of the staff. Summary of the invention

[0004] The purpose of the present invention is to provide a metal waste recovery device with extrusion and filtering functions to solve the technical problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions.

[0006] A metal waste recycling device comprises a chassis, a transfer vehicle body, a pushing plate and a filtering system. A feed port is provided on one side of the top of the chassis, and an exhaust port is provided on the other side. A material guiding pipe and an extrusion chamber are provided in sequence below the feed port in the chassis. The material guiding pipe is communicated with the feed port and the extrusion chamber respectively. The transfer vehicle body is arranged on one side of the chassis and corresponds to the position of the extrusion chamber, and is used to receive the waste in the extrusion chamber. The pushing plate is slidably installed in the extrusion chamber. A filtering chamber and an installation chamber are provided in sequence below the exhaust port in the chassis. A driving mechanism for driving the pushing plate to translate and adjust is provided in the installation chamber. The filtering system is arranged in the filtering chamber, and is used to filter out powder and particles in the recovered metal waste.

[0007] By driving the pushing plate to move through the operation of the driving mechanism, the metal waste can be squeezed, the accumulated metal waste is compressed, and then pushed into the transfer vehicle body, thereby greatly reducing the gaps between the wastes, avoiding excessive fluffiness of the waste, and making efficient and reasonable use of the internal space of the transfer vehicle. In addition, in the process of metal waste falling in the material guide pipe, the filtering system generates negative pressure airflow, which can absorb and collect the powder particles attached to the surface of the waste. On the one hand, it can prevent the powder particles from scattering randomly in the subsequent recycling process and causing pollution. On the other hand, the powder particles are collected as waste, which is convenient for later recycling and reuse, reducing the waste rate of metal raw materials, killing two birds with one stone.

[0008] Preferably, the driving mechanism includes a fixed seat, an electric push cylinder and a connecting seat, the fixed seat is fixed in the installation cavity, the electric push cylinder is horizontally fixed to the side of the fixed seat, and the telescopic rod extends through to the other side of the fixed seat, the connecting seat is installed on the end of the telescopic rod of the electric push cylinder, the connecting seat is fixedly connected to the surface of the pushing plate, a sliding sleeve is fixed through the fixed seat, a guide rod is fixed on the pushing plate, and the guide rod slides through and is installed in the sliding sleeve.

[0009] Working through the electric push cylinder, its telescopic rod and the connecting seat can drive the pushing plate to slide synchronously, providing drive for the extrusion and reset actions of the pushing plate. When the pushing plate moves, it can drive the guide rod to slide synchronously in the sliding sleeve, playing a guiding and limiting role for the pushing plate, ensuring that the movement process of the pushing plate is smooth and stable enough.

[0010] The driving mechanism drives the pushing plate to move, and the metal waste falling into the extrusion chamber is pushed from the rectangular discharge frame into the transfer vehicle body by the pushing plate. Under the blocking effect of the counterweight block seat, the loosely accumulated waste can be squeezed and compressed. Then the driving mechanism needs to continue to work to push the pushing plate to continue feeding, thereby pushing the waste and the counterweight block seat to move, making room for the next waste to enter, until the waste in the transfer vehicle body is full, the transfer vehicle body is withdrawn from the side of the chassis, and the transfer vehicle body is used to facilitate the transfer of the waste to the next process. Secondly, the driving mechanism drives the pushing plate to move, and the waste is pushed into the transfer vehicle body by the driving mechanism. The push plate is moved, and the metal scraps falling into the extrusion cavity are pushed from the rectangular discharge frame to the transfer vehicle body by the push plate, so the scraps can be automatically transferred from the extrusion cavity to the transfer vehicle body, with a high degree of automation, replacing traditional manual operations, saving time and effort, and having high work efficiency. After the scraps are extruded by the cooperation of the push plate and the counterweight block seat, the driving mechanism continues to work to push the push plate to feed, thereby pushing the scraps and the counterweight block seat to move, making room for the next scrap to enter, ensuring that the multiple pushing processes are more continuous, and the overall structural layout is reasonable and highly practical.

[0011] Preferably, a rectangular discharge frame protruding outward is fixed to the side of the chassis, the rectangular discharge frame is communicated with the extrusion chamber, and the pushing plate can slide through the rectangular discharge frame in a matching manner. A material guide port for the rectangular discharge frame to be inserted into one side of the transfer vehicle body is provided, and universal wheels are respectively installed at the four top corners of the bottom of the transfer vehicle body, each universal wheel has a braking effect, and a counterweight block seat is placed in the transfer vehicle body, and the counterweight block seat slides and fits with the inner wall of the transfer vehicle body.

[0012] Preferably, a cover plate is provided on the top of the transfer vehicle body, and the cover plate has a flip-up opening and closing effect.

[0013] By setting a cover plate, the top port of the transfer vehicle body is blocked to prevent the waste inside the transfer vehicle body from spreading upward under the squeeze and leaking to the outside. When taking the material, just flip the cover plate open, which is convenient and quick to operate.

[0014] Preferably, a full material sensor is provided on the inner wall of the extrusion chamber, and the full material sensor is electrically connected to a controller for controlling the operation of the electric push cylinder. A micro-touch switch is installed on the inner wall of the transfer vehicle body away from the material guide port, and the micro-touch switch is electrically connected to an alarm arranged on the transfer vehicle body.

[0015] When the full material sensor detects that the amount of waste material in the extrusion chamber has accumulated to a predetermined amount, it sends a signal to the controller, which controls the electric push cylinder to work to push the pushing plate to move to achieve the extrusion of the waste material, thereby effectively controlling the amount of waste material accumulated in the extrusion chamber to avoid excessive accumulation of waste material and spreading into the material guide pipe, causing the waste material to move over the pushing plate to the other side and affect the normal extrusion of the waste material. In addition, when the counterweight stop seat contacts the micro-touch switch during the process of being pushed and transferred, it means that the transfer vehicle is fully loaded. The micro-touch switch sends a signal to the alarm, triggering the alarm to alert the staff to the full load of the transfer vehicle so that they can deal with it in time, thereby achieving real-time monitoring of the loading volume of the transfer vehicle.

[0016] Preferably, the filtration system includes a pair of filter cartridges, an air guide mechanism and a first guide pipe, the two filter cartridges are symmetrically arranged in the filter chamber, the filter chamber is communicated with the exhaust port, the air guide mechanism is arranged in the filter chamber and located above the filter cartridge, and is used to form a vertical upward airflow in the filter chamber, one end of the first guide pipe is communicated with the input end of one of the filter cartridges, and the other end is communicated with the material guide pipe near its bottom end, the air guide mechanism includes a mounting frame installed in the filter chamber, an impeller installed on the mounting frame, and a drive motor, and the output shaft of the drive motor is fixedly connected to the shaft end of the impeller.

[0017] When the waste falls in the material guide pipe, an upward negative pressure airflow is generated through the operation of the air guide mechanism, and the airflow flows from the exhaust port to the outside of the chassis. Under the connection of the first air guide pipe, the airflow in the material guide pipe can be sucked into the filter cartridge, and the powder particles attached to the waste are sucked into the filter cartridge for filtration under the action of negative pressure suction and accumulated in the filter cartridge, thereby achieving effective filtration and collection of powder particles.

[0018] Preferably, the input end of the other filter cartridge is connected to a second flow guide pipe, the other end of the second flow guide pipe is connected to the material guide pipe near its top end, a first control valve is installed on the first flow guide pipe, a second control valve is installed on the second flow guide pipe, and interception nets are installed in the first flow guide pipe near the material guide pipe and in the second flow guide pipe near the material guide pipe.

[0019] By closing the first guide pipe and opening the second guide pipe, the powder and particles at the upper part of the material guide pipe can be filtered and collected. By utilizing the alternating opening and closing of the first guide pipe and the second guide pipe, the filtering effect of the powder and particles in the material guide pipe can be guaranteed. By setting an interception net, small weight waste can be effectively prevented from being sucked into the first guide pipe or the second guide pipe to cause pollution.

[0020] Preferably, a precision filter is installed in the exhaust port.

[0021] The air can be filtered more finely through precision filters to ensure the quality of the exhausted air.

[0022] Preferably, maintenance ports communicating with the filter chamber are respectively provided at positions corresponding to the two filter cartridges on the sides of the chassis, and two sealing plates respectively used to seal the maintenance ports are detachably mounted on the sides of the chassis.

[0023] The maintenance port is provided to facilitate maintenance and replacement of the filter cartridge when excessive dust and particles accumulate in the filter cartridge.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0025] 1. The present invention utilizes the operation of the driving mechanism to push the pushing plate to move in the extrusion chamber, which can squeeze and shrink the metal waste falling into the extrusion chamber, and then when the waste is transferred to the transfer vehicle body, the gap between the wastes can be greatly reduced to avoid excessive fluffiness of the waste, and the space inside the transfer vehicle body can be efficiently and reasonably utilized. In addition, after each operation of the driving mechanism to push the pushing plate to perform an extrusion action, the driving mechanism resets the pushing plate to slide and reset, and the space in the extrusion chamber can be re-released, so that the metal waste can fall into the extrusion chamber again to repeat the waste extrusion work, and the overall structural layout is reasonable.

[0026] 2. In the process of metal waste falling in the material guiding pipe, the filtering system of the present invention generates negative pressure airflow, which can absorb and collect the powder particles attached to the surface of the waste. On the one hand, it prevents the powder particles from scattering randomly in the subsequent recycling process and causing pollution. On the other hand, the powder particles are collected as waste, which is convenient for later recycling and reuse, reducing the waste rate of metal raw materials, thus killing two birds with one stone.

[0027] 3. The present invention drives the pushing plate to move through the operation of the driving mechanism, and utilizes the pushing plate to push the metal waste that falls into the extrusion cavity from the rectangular discharge frame into the transfer vehicle body, so that the waste can be automatically transferred from the extrusion cavity to the transfer vehicle body, with a high degree of automation, replacing the traditional manual operation, saving time and effort, and having high work efficiency. In addition, after the waste is extruded by utilizing the cooperation of the pushing plate and the counterweight block seat, the driving mechanism continues to work to push the pushing plate to feed, thereby pushing the waste and the counterweight block seat to move, making room for the next waste entry, ensuring that the multiple pushing processes are more coherent, and the overall structural layout is reasonable and highly practical.

[0028] 4. When the full material sensor of the present invention detects that the amount of waste material in the extrusion chamber has accumulated to a predetermined amount, it sends a signal to the controller, and the controller controls the electric push cylinder to work, so as to push the pushing plate to move to realize the extrusion of the waste material, thereby effectively controlling the amount of waste material accumulated in the extrusion chamber, avoiding excessive accumulation of waste material and spreading it into the material guide pipe, causing the waste material to move over the pushing plate to the other side and affect the normal extrusion of the waste material. In addition, when the counterweight stop seat contacts the micro-touch switch during the process of being pushed and transferred, it means that the transfer vehicle body is fully loaded. The micro-touch switch sends a signal to the alarm, triggering the alarm to alarm, reminding the staff to pay attention to the full load of the transfer vehicle body so that they can deal with it in time, thereby realizing real-time monitoring of the loading amount in the transfer vehicle body.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 10 The present invention provides a metal waste recycling device, including a chassis 1, a transfer vehicle body 2, a pushing plate 3 and a filtering system 5. A feed port 11 is provided on one side of the top of the chassis 1, and an exhaust port 17 is provided on the other side. A material guide pipe 13 and an extrusion chamber 12 are sequentially provided below the feed port 11 in the chassis 1. The material guide pipe 13 is communicated with the feed port 11 and the extrusion chamber 12 respectively. The transfer vehicle body 2 is arranged on one side of the chassis 1 and corresponds to the position of the extrusion chamber 12, and is used to receive the waste in the extrusion chamber 12. The pushing plate 3 is slidably installed in the extrusion chamber 12. A filter chamber 16 and an installation chamber 15 are sequentially provided below the exhaust port 17 in the chassis 1. A driving mechanism 4 for driving the pushing plate 3 to translate and adjust is provided in the installation chamber 15. The filtering system 5 is arranged in the filter chamber 16, and is used to filter out the powder particles in the recovered metal waste.

[0033] When the metal waste recycling device is used to recycle metal waste, the metal waste is put into the material guide pipe 13 from the feed port 11. Under the action of gravity, the metal waste will eventually fall downward into the extrusion chamber 12. When the metal waste in the extrusion chamber 12 is filled, the driving mechanism 4 drives the pushing plate 3 to move, so that the metal waste can be squeezed, the accumulated metal waste is compacted, and then pushed into the transfer vehicle body 2, thereby greatly reducing the gap between the wastes, avoiding excessive fluffiness of the waste, and making efficient and reasonable use of the internal space of the transfer vehicle.

[0034] In addition, when the metal waste falls in the material guide pipe 13, the negative pressure airflow is generated by the operation of the filtering system 5, which can absorb and collect the powder particles attached to the surface of the waste. On the one hand, it can prevent the powder particles from floating around in the subsequent recycling process and causing pollution. On the other hand, the powder particles are collected as waste, which is convenient for later recycling and reuse, reducing the waste rate of metal raw materials, killing two birds with one stone.

[0035] In addition, first guide wheels 31 are respectively installed at the four top corners of the pushing plate 3, and second guide wheels 32 are installed on both sides of the pushing plate 3. When the pushing plate 3 slides, the two upper first guide wheels 31 roll against the inner top wall of the extrusion cavity 12, the two lower first guide wheels 31 roll against the inner bottom wall of the extrusion cavity 12, and the two second guide wheels 32 roll against the inner walls on both sides of the extrusion cavity 12, thereby reducing the friction force on the pushing plate 3 and ensuring that the pushing plate 3 moves more smoothly.

[0036] Specifically, the driving mechanism 4 includes a fixed seat 41, an electric push cylinder 42 and a connecting seat 43. The fixed seat 41 is fixed in the installation cavity 15. The electric push cylinder 42 is horizontally fixed on the side of the fixed seat 41, and the telescopic rod extends through the other side of the fixed seat 41. The connecting seat 43 is installed on the end of the telescopic rod of the electric push cylinder 42. The connecting seat 43 is fixedly connected to the surface of the pushing plate 3. When the electric push cylinder 42 works, its telescopic rod is connected to the connecting seat 43 to drive the pushing plate 3 to slide synchronously, thereby providing drive for the extrusion and reset actions of the pushing plate 3.

[0037] A sliding sleeve 44 is fixed through the fixed seat 41, and a guide rod 45 is fixed on the pushing plate 3. The guide rod 45 is slidably installed in the sliding sleeve 44. When the pushing plate 3 moves, the guide rod 45 can be driven to slide synchronously in the sliding sleeve 44, which plays a guiding and limiting role for the pushing plate 3, thereby ensuring that the movement process of the pushing plate 3 is smooth and stable enough.

[0038] Specifically, a rectangular discharge frame 14 protruding outward is fixed to the side of the chassis 1, and the rectangular discharge frame 14 is communicated with the extrusion chamber 12. The pushing plate 3 can slide through the rectangular discharge frame 14 in a matching manner. A guide port 21 is provided on one side of the transfer vehicle body 2 for the rectangular discharge frame 14 to be inserted into. Universal wheels 201 are respectively installed at the four top corners of the bottom of the transfer vehicle body 2, and each universal wheel 201 has a braking effect. A counterweight block seat 22 is placed in the transfer vehicle body 2, and the counterweight block seat 22 slides and fits with the inner wall of the transfer vehicle body 2, pushing the transfer vehicle body 2 to the side of the chassis 1, and ensuring that the rectangular discharge frame 14 is aligned and inserted into the guide port 21, so as to realize the connection between the transfer vehicle body 2 and the extrusion chamber 12. At the same time, the universal wheel 201 needs to be adjusted to a braking state to prevent the transfer vehicle body 2 from moving at will and ensure the stability of the transfer vehicle body 2 during loading.

[0039] The driving mechanism 4 is used to push the pushing plate 3 to move, and the pushing plate 3 is used to push the metal waste falling into the extrusion chamber 12 from the rectangular discharge frame 14 to the transfer vehicle body 2. Under the blocking action of the counterweight block seat 22, the fluffy accumulated waste can be squeezed and compressed. Then the driving mechanism 4 needs to continue to work to push the pushing plate 3 to continue feeding, thereby pushing the waste and the counterweight block seat 22 to move, making room for the next waste entry, until the waste in the transfer vehicle body 2 is full, the transfer vehicle body 2 is withdrawn from the side of the chassis 1, and the transfer vehicle body 2 is used to facilitate the transfer of the waste to the next process. Secondly, the driving mechanism 4 is used to push the pushing plate 3 to move, and the pushing plate 3 is used to push the metal waste falling into the extrusion chamber 12 from the rectangular discharge frame 14 to the transfer vehicle body 2, so that the waste can be automatically transferred from the extrusion chamber 12 to the transfer vehicle body 2, with a high degree of automation, replacing traditional manual operations, saving time and effort, and high work efficiency.

[0040] After the waste is squeezed by the cooperation of the pushing plate 3 and the counterweight block seat 22, the driving mechanism 4 continues to work to push the pushing plate 3 to feed, thereby pushing the waste and the counterweight block seat 22 to move, making room for the next waste to enter, ensuring that the multiple pushing processes are more coherent, the overall structural layout is reasonable, and the practicality is high.

[0041] Specifically, a cover plate 24 is provided on the top of the transfer vehicle body 2, and the cover plate 24 has a flip-up opening and closing effect. By setting the cover plate 24, the top port of the transfer vehicle body 2 is blocked to prevent the waste in the transfer vehicle body 2 from spreading upward under the extrusion and leaking to the outside. When taking the material, the cover plate 24 can be flipped open, which is convenient and quick to operate.

[0042] Specifically, a full material sensor 121 is provided on the inner wall of the extrusion chamber 12. The full material sensor 121 is electrically connected to a controller (not shown in the figure) for controlling the operation of the electric push cylinder 42. The full material sensor 121 can be used to monitor the amount of waste accumulated in the extrusion chamber 12. When the full material sensor 121 detects that the amount of waste accumulated in the extrusion chamber 12 reaches a predetermined amount, a signal is sent to the controller, and the controller controls the electric push cylinder 42 to work, so as to push the pushing plate 3 to move and realize the extrusion of the waste. Therefore, the amount of waste accumulated in the extrusion chamber 12 can be effectively controlled to avoid excessive accumulation of waste and spread to the material guide pipe 13, causing the waste to move over the pushing plate 3 to the other side and affect the normal extrusion of the waste.

[0043] A micro-touch switch 23 is installed on the inner wall of the transfer vehicle body 2 away from the material guide port 21. The micro-touch switch 23 is electrically connected to an alarm (not shown in the figure) arranged on the transfer vehicle body 2. When the counterweight block seat 22 contacts the micro-touch switch 23 during the process of being pushed and transferred, it means that the transfer vehicle body 2 is fully loaded. The micro-touch switch 23 sends a signal to the alarm, triggering the alarm to alert the staff to pay attention to the full load of the transfer vehicle body 2 so that they can deal with it in time, thereby realizing real-time monitoring of the loading amount in the transfer vehicle body 2.

[0044] Specifically, the filtration system 5 includes a pair of filter cartridges 51, an air guide mechanism 52 and a first air guide pipe 53. The two filter cartridges 51 are symmetrically arranged in the filter chamber 16. The filter chamber 16 is communicated with the exhaust port 17. The air guide mechanism 52 is arranged in the filter chamber 16 and is located above the filter cartridges 51, and is used to form a vertical upward airflow in the filter chamber 16. One end of the first air guide pipe 53 is communicated with the input end of one of the filter cartridges 51, and the other end is communicated with the material guide pipe 13 near its bottom end. When the waste falls in the material guide pipe 13, an upward negative pressure airflow is generated by the operation of the air guide mechanism 52, and the airflow flows from the exhaust port 17 to the outside of the chassis 1. Under the communication effect of the first air guide pipe 53, the airflow in the material guide pipe 13 can be sucked into the filter cartridge 51, and the powder particles attached to the waste are sucked into the filter cartridge 51 under the action of the negative pressure suction force for filtration and accumulated in the filter cartridge 51, thereby achieving effective filtration and collection of the powder particles.

[0045] The air guide mechanism 52 includes a mounting frame 521 installed in the filter chamber 16, an impeller 522 installed on the mounting frame 521, and a driving motor 523. The output shaft of the driving motor 523 is fixedly connected to the shaft end of the impeller 522. When the driving motor 523 works, its output shaft drives the impeller 522 to rotate, thereby realizing the function of suction and air guiding.

[0046] Specifically, the input end of the other filter cartridge 51 is connected to the second guide pipe 54, and the other end of the second guide pipe 54 is connected to the material guide pipe 13 near its top end. The first control valve 531 is installed on the first guide pipe 53, and the second control valve 541 is installed on the second guide pipe 54. By adjusting the first control valve 531 and the second control valve 541, it is convenient to control the on-off of the first guide pipe 53 and the second guide pipe 54. Intercepting nets (not shown in the figure) are installed near the material guide pipe 13 in the first guide pipe 53 and near the material guide pipe 13 in the second guide pipe 54, which can effectively prevent small weight waste from being sucked into the first guide pipe 53 or the second guide pipe 54 and causing pollution.

[0047] By closing the first guide tube 53 and opening the second guide tube 54, the powder and particles at the upper part of the material guide tube 13 can be filtered and collected. The alternating opening and closing of the first guide tube 53 and the second guide tube 54 can ensure the filtering effect of the powder and particles in the material guide tube 13.

[0048] Specifically, a precision filter 171 is installed in the exhaust port 17, and the air after the powder particles are filtered out is discharged from the exhaust port 17. The air can be filtered more finely again through the precision filter 171, so as to ensure the quality of the discharged air.

[0049] Specifically, maintenance ports 511 that penetrate the filter chamber 16 are respectively provided at positions corresponding to the positions of the two filter cartridges 51 on the sides of the chassis 1. Two sealing plates 512 that are respectively used to block the maintenance ports 511 are detachably installed on the sides of the chassis 1. By providing the maintenance ports 511, it is convenient to maintain and replace the filter cartridge 51 when excessive dust and particulate matter accumulates in the filter cartridge 51.
