Description

Technical Field

[0001] This invention relates to the field of grinding technology, and in particular to an aluminum alloy cookware grinding workbench with a waste collection function. Background Technology

[0002] The grinding and polishing process of aluminum alloy cookware generates a large amount of metal shavings and dust mixtures with a wide particle size distribution. In the existing technology, ordinary grinding workbenches are usually only equipped with simple dust removal devices, which have the following significant drawbacks: First, in the mixed recycling waste, coarse metal shavings with high recycling value are mixed with fine dust that is difficult to melt. Fine dust will significantly increase flux consumption, prolong melting time and increase energy consumption during the remelting process, which seriously reduces the overall economic value of waste recycling. Second, traditional cyclone separators have limited ability to capture dust below the micron level, while bag filters are prone to caking or fire risks when dealing with high concentrations of metal dust. Single separation technology cannot achieve effective classification of coarse and fine mixed waste. Summary of the Invention

To this end, we propose an aluminum alloy cookware grinding workbench with waste collection function.

[0004] To achieve the above objectives, this application adopts the following technical solution: an aluminum alloy cookware polishing workbench with waste collection function, comprising: a workbench, a coarse waste collection box, a fine waste collection box, and a waste collection mechanism, wherein a polishing machine is installed on the upper end of the workbench;

Multiple piezoelectric ceramic actuators are fixedly connected to the top of the primary separation cylinder, and the multiple piezoelectric ceramic actuators are arranged in a circular array. A secondary separation cylinder is fixedly connected to the upper end of the primary separation cylinder, and an exhaust pipe is fixedly connected to the top of the primary separation cylinder. The upper end of the exhaust pipe is connected to the secondary separation cylinder.

[0006] Preferably, an electromagnetic ring is fixedly connected to the lower end of the primary separation cylinder, and the lower end of the electromagnetic ring has multiple mounting holes. The upper end of the coarse waste recycling box is fixedly connected to multiple magnetic columns that cooperate with the mounting holes.

[0007] Preferably, a secondary recovery mechanism is installed inside the secondary separation cylinder. The secondary recovery mechanism includes a conductive sleeve fixedly connected to the bottom of the secondary separation cylinder by multiple fixed shafts. The conductive sleeve is connected to an external power source through wires. An annular frame is fixedly connected to the inner wall of the secondary separation cylinder. Multiple rotating shafts are rotatably connected between the inner wall of the annular frame and the side wall of the conductive sleeve. Each rotating shaft has a blade fixedly connected to its side wall.

[0008] Preferably, the secondary recycling mechanism further includes a metal dust collection cylinder fixedly connected to the inner wall of the secondary separation cylinder, and the metal dust collection cylinder is grounded through a wire.

[0009] Preferably, both the shaft and the blades are made of a metal material with good electrical conductivity, and the edges of the blades are serrated.

[0010] Preferably, a material receiving rack is fixedly connected to the inner wall of the secondary separation cylinder, and the material receiving rack is located below the metal dust collection cylinder.

[0011] Preferably, the side wall of the secondary separation cylinder is fixedly connected to an installation ring, which is made of an electromagnet. The fine waste recycling box is made of magnetic material. The inner wall of the receiving rack is fixedly connected to multiple discharge pipes, the other end of which passes through the side wall of the installation ring. Each discharge pipe is equipped with an airlock valve on its inner wall.

[0012] Preferably, an adjustment mechanism is installed inside the conductive sleeve. The adjustment mechanism includes an insulating mounting pad fixedly connected to the top of the conductive sleeve. A micro servo motor is fixedly connected to the lower end of the insulating mounting pad. A helical gear ring is fixedly connected to the side wall of the output end of the micro servo motor via a fixing rod. One end of each of the plurality of rotating shafts extends into the conductive sleeve and is fixedly connected to a helical gear. The helical gear meshes with the helical gear ring. A light scattering sensor is fixedly connected to the inner wall of the collecting pipe. The light scattering sensor is connected to the micro servo motor via a PLC control circuit.

[0013] Preferably, multiple electromagnetic vibrators are fixedly connected to the side wall of the secondary separation cylinder.

[0014] Preferably, the upper end of the secondary separation cylinder is provided with an exhaust port, and the side wall of the workbench is provided with a ventilation port.

[0015] The technical effects and advantages of this invention are as follows:

[0016] In this invention, by setting up a waste recycling mechanism and a secondary recycling mechanism, efficient physical separation of coarse metal shavings and fine hazardous dust is achieved. The purity of coarse particles is improved, and they can be directly reused as high-quality furnace charge. Fine dust is collected centrally and safely, and can be professionally processed or utilized as a resource. This solves the problem of low smelting value and high processing cost of mixed waste from the source, and greatly improves the economic benefits of resource recycling.

[0017] In this invention, during the first-stage separation, a reverse acoustic vortex is actively generated by a piezoelectric ceramic actuator, which superimposes with the main vortex to produce strong shear turbulence, enhancing the inertial settling efficiency of large particles. During the second-stage separation, mechanical centrifugal concentration is combined with electrostatic adsorption and capture. The tip discharge effect of the cyclone plate tip rapidly charges the fine particles, which are then captured under the action of strong electrostatic force. The capture efficiency of submicron fine dust reaches an extremely high level, fundamentally reducing the risk of explosion.

[0018] In this invention, an adjustment mechanism is set up, an integrated light scattering sensor is used to monitor the dust concentration of the inlet airflow in real time, and a micro servo motor is controlled by a PLC system to dynamically adjust the blade angle. When the concentration is high, the angle is increased to enhance centrifugal concentration and ensure processing capacity. When the concentration is low, the angle is decreased to reduce resistance and energy consumption, so as to achieve a dynamic optimal balance between energy efficiency and separation efficiency, and a high level of intelligence.

Detailed Implementation

[0031] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0032] Reference Figures 1-4 As shown, the present invention provides a technical solution: an aluminum alloy cookware grinding workbench with waste collection function, including a workbench 1, a coarse waste recycling bin 2, a fine waste recycling bin 3 and a waste recycling mechanism. A grinding machine 4 is installed on the upper end of the workbench 1. The grinding machine 4 consists of a rotatable base, a rotatable cookware fixing mold, a drive motor and a grinding wheel. This is the prior art and will not be described in detail here.

[0033] The waste recycling mechanism includes a primary separation cylinder 5 fixedly connected to the inner wall of the workbench 1 via a bracket. A negative pressure chamber 6 is provided inside the workbench 1. Multiple dust suction holes 7 are provided at the top of the negative pressure chamber 6. The negative pressure chamber 6 is connected to the primary separation cylinder 5 via a collection pipe 8. A negative pressure fan 9 is fixedly connected to the inner wall of the collection pipe 8. Multiple piezoelectric ceramic actuators 10 are fixedly connected to the top of the primary separation cylinder 5, and the multiple piezoelectric ceramic actuators 10 are arranged in a circular array. A secondary separation cylinder 11 is fixedly connected to the upper end of the primary separation cylinder 5. An exhaust pipe 12 is fixedly connected to the top of the primary separation cylinder 5, and the upper end of the exhaust pipe 12 is connected to the secondary separation cylinder 11. Multiple electromagnetic vibrators 28 are fixedly connected to the side wall of the secondary separation cylinder 11. The electromagnetic vibrators 28 can use electromagnetic force to generate high-frequency, high-intensity mechanical impact to remove dust adhering to the surface of the equipment. This is existing technology and will not be described in detail here.

[0034] It should be noted that the piezoelectric ceramic actuator 10 is a precision actuator that can directly convert electrical energy into mechanical displacement or force. When energized, it will produce extremely small but rapid and precise deformation or vibration. This is existing technology and will not be elaborated here.

[0035] The cookware to be polished is placed on the mold, and then the polishing machine 4 is started. The rotating base can rotate the cookware on the mold to the polishing wheel. Then the drive motor drives the polishing wheel to rotate, and the mold rotates, which can polish the outer wall of the aluminum alloy cookware. During polishing, the negative pressure fan 9 is started at the same time to generate suction force. The waste generated by polishing is sucked into the negative pressure chamber 6 through the dust suction hole 7. Then the waste will enter the collection pipe 8 with the airflow, and finally enter the primary separation cylinder 5 tangentially from the collection pipe 8. The airflow containing waste will rotate and flow downward at high speed along the inner wall of the primary separation cylinder 5 to form the main vortex. Large particles of waste will gain a lot of centrifugal force and be thrown towards the inner wall of the primary separation cylinder 5. They will flow downward along the inner wall of the primary separation cylinder 5 and finally be discharged into the coarse particle collection box 2 through the bottom outlet. Simultaneously, the piezoelectric ceramic actuator 10 is started to apply 20-50 At a high-frequency alternating voltage of kHz, the piezoelectric ceramic actuator 10 generates rapid radial expansion and contraction vibrations. This high-frequency vibration pushes the surrounding air, exciting a high-intensity, high-frequency acoustic field in the top central region of the first-stage separation cylinder 5. This acoustic field interacts with the main vortex, forming a strong velocity shear and turbulence disturbance zone in the upper part of the first-stage separation cylinder 5. The equivalent effect of this disturbance zone is to generate a reverse momentum impact on the main vortex, thus forming a reverse vortex. When the main vortex and the reverse vortex meet, this region generates extremely high velocity shear gradients and turbulence intensity. For large particles, their inertia is large, and under the impact of violent reverse airflow and sudden changes in direction, they cannot follow the streamline, thus resulting in strong inertial collisions and turbulence. The diffusion of the flow and the rapid dissipation of kinetic energy can accelerate the settling of particles toward the wall. For fine particles and air, their inertia is small, making it easier to follow the complex composite streamline motion. Under the disturbance of the reverse vortex and the agglomeration effect of the sound wave, some fine particles are pushed into the strong centrifugal zone on the periphery of the main vortex, or are separated after agglomeration. However, most submicron-sized fine particles will flow upward with the inner swirling flow in the central area of ​​the first-stage separation cylinder 5 into the exhaust pipe 12, and then enter the second-stage separation cylinder 11 from the exhaust pipe 12. This allows the waste generated from grinding aluminum alloy cookware to be classified and recycled according to its coarseness, avoiding the increase in flux consumption, prolonged smelting time, and increased energy consumption in the waste during remelting, thus increasing the processing cost.

[0036] Reference Figure 5As shown, an electromagnetic ring 31 is fixedly connected to the lower end of the primary separation cylinder 5. The electromagnetic ring 31 is made of an electromagnet and has multiple mounting holes 14 at its lower end. Multiple magnetic pillars 13 that cooperate with the mounting holes 14 are fixedly connected to the upper end of the coarse waste recycling box 2. When the magnetic pillars 13 are inserted into the mounting holes 14, the electromagnetic ring 31 is energized and generates magnetism. The magnetic pillars 13 will be firmly attracted to the mounting holes 14 under the action of magnetic attraction, thereby installing the coarse waste recycling box 2 at the lower end of the primary separation cylinder 5 for easy waste recycling. When the electromagnetic ring 31 is de-energized, the coarse waste recycling box 2 can be removed for easy disassembly and removal of waste.

[0037] Reference Figure 6 As shown, a secondary recovery mechanism is installed inside the secondary separation cylinder 11. The secondary recovery mechanism includes a conductive sleeve 15 fixedly connected to the bottom of the secondary separation cylinder 11 by multiple fixed shafts. The conductive sleeve 15 is connected to an external power source through wires. An annular frame 16 is fixedly connected to the inner wall of the secondary separation cylinder 11. Multiple rotating shafts 17 are rotatably connected between the inner wall of the annular frame 16 and the side wall of the conductive sleeve 15. Each rotating shaft 17 has a blade 18 fixedly connected to its side wall. Both the rotating shaft 17 and the blade 18 are made of a metal material with good conductivity, and the edge of the blade 18 is serrated.

[0038] The secondary recycling mechanism also includes a metal dust collection cylinder 19 fixedly connected to the inner wall of the secondary separation cylinder 11, and the metal dust collection cylinder 19 is grounded through a wire.

[0039] A material receiving rack 20 is fixedly connected to the inner wall of the secondary separation cylinder 11, and the material receiving rack 20 is located below the metal dust collection cylinder 19.

[0040] A mounting ring 21 is fixedly connected to the side wall of the secondary separation cylinder 11. The mounting ring 21 is made of an electromagnet, and the fine waste recovery box 3 is made of magnetic material. The fine waste recovery box 3 is fitted onto the side wall of the mounting ring 21. Then, the mounting ring 21 is energized to generate magnetism, and the fine waste recovery box 3 will be firmly attracted to the side wall of the mounting ring 21, which facilitates the disassembly and retrieval of the fine waste recovery box 3. A number of discharge pipes 22 are fixedly connected to the inner wall of the receiving rack 20. The other end of each discharge pipe 22 passes through the side wall of the mounting ring 21, and each discharge pipe 22 is equipped with an airlock valve. The airlock valve is a special valve that can effectively lock the gas while continuously discharging solid materials to prevent gas leakage or cross-contamination. The airlock valve can prevent external gas from being sucked back into the secondary separation cylinder 11, and avoid disrupting the airflow organization in the secondary separation cylinder 11, thereby reducing the capture efficiency of fine dust. The airlock valve is existing technology and will not be described in detail here.

[0041] Furthermore, the airflow containing fine dust entering the secondary separation cylinder 11 flows upward. When it passes through the vortex plate composed of multiple circularly arranged inclined blades 18, the airflow is forced to rotate by the blades 18, forming a secondary vortex and generating centrifugal force. This centrifugal force pre-concentrates the dust in space to the inner wall area of ​​the secondary separation cylinder 11, significantly increasing the probability of fine particles entering the effective range of the subsequent electrostatic field. Simultaneously, the external power supply is activated, energizing the conductive sleeve 15, which in turn energizes the rotating shaft 17 and the blades 18. Since the edges of the blades 18 are serrated and have sharp points, tip discharge is formed, resulting in extremely high electric field strength at the edges of the blades 18. This ionizes the surrounding gas molecules, generating a large number of positive and negative ions. When the airflow carrying fine particles... As the particles pass through, they collide with ions and become charged within microseconds. The grounded metal dust collection cylinder 19 forms a strong radial non-uniform electric field with the high-voltage blades 18. The charged particles move towards the wall of the metal dust collection cylinder 19 under centrifugal force and are attracted by strong Coulomb force. The particles are firmly adsorbed onto the inner wall of the metal dust collection cylinder 19, achieving efficient collection of fine dust. By periodically activating the electromagnetic vibrator 28 to strike the secondary separation cylinder 11, the fine dust layer attached to the inner wall of the metal dust collection cylinder 19 will fall into the receiving rack 20. Then, the fine dust will enter the fine waste recycling box 3 through the discharge pipe 22 for collection. Finally, the clean air will be discharged through the exhaust port 29 above.

[0042] Reference Figures 7-10 As shown, an adjustment mechanism is installed inside the conductive sleeve 15. The adjustment mechanism includes an insulating mounting pad 23 fixedly connected to the top of the conductive sleeve 15. A micro servo motor 24 is fixedly connected to the lower end of the insulating mounting pad 23. A helical gear ring 25 is fixedly connected to the side wall of the output end of the micro servo motor 24 through a fixing rod. One end of multiple rotating shafts 17 extends into the conductive sleeve 15 and is fixedly connected to a helical gear 26. The helical gear 26 meshes with the helical gear ring 25. A light scattering sensor 27 is fixedly connected to the inner wall of the collection pipe 8. The light scattering sensor 27 and the micro servo motor 24 are connected through a PLC control circuit.

[0043] Furthermore, when waste enters the collection pipe 8, the light scattering sensor 27 can monitor the dust concentration. When the dust concentration in the monitored airflow is high, the light scattering sensor 27 will send a signal, which will control the micro servo motor 24 to rotate forward via the PLC control circuit. This will drive the helical gear ring 25 to rotate forward, which in turn drives the helical gear 26 to rotate forward, thereby driving the rotating shaft 17 to rotate forward. This will increase the opening angle between the multiple blades 18. At this time, the airflow passing through the blades 18 will generate a stronger vortex, which in turn will generate a stronger centrifugal force. The greater centrifugal force can carry more and more dust particles. Fine particles are thrown toward the cylinder wall area, enabling more effective spatial concentration of dust before it enters the electrostatic area, reducing the burden on the subsequent electrostatic field. When the light scattering sensor 27 detects a low dust concentration, it will cause the micro servo motor 24 to reverse, reducing the opening angle between the blades 18. The airflow passing through the blades 18 will generate a smaller vortex, thereby reducing system energy consumption, improving electrostatic collection efficiency, and thus reducing the noise of the entire system during operation. Therefore, by monitoring the dust concentration and automatically adjusting the angle of the blades 18, a dynamic optimal balance can be achieved between energy efficiency and collection efficiency.

[0044] The upper end of the secondary separation cylinder 11 is provided with an exhaust port 29, and the clean air inside the secondary separation cylinder 11 will be discharged through the exhaust port 29. The side wall of the workbench 1 is provided with a ventilation port 30.

[0045] Working principle: First, the magnetic column 13 is inserted into the mounting hole 14. Then, the electromagnetic ring 31 is energized to generate magnetism, and the magnetic column 13 will be firmly attracted to the mounting hole 14 under the action of magnetic attraction. This allows the coarse waste recycling box 2 to be installed at the lower end of the primary separation cylinder 5, facilitating waste recycling. Next, the fine waste recycling box 3 is fitted onto the side wall of the mounting ring 21. The mounting ring 21 is then energized to generate magnetism, causing the fine waste recycling box 3 to be firmly attracted to the side wall of the mounting ring 21. The pot to be ground is then placed on the mold. The grinding machine 4 is then started. The rotating base rotates the pot on the mold to the grinding wheel. The drive motor then drives the grinding wheel to rotate, and the mold rotates as well, thus... The outer wall of the aluminum alloy cookware is polished. Simultaneously, a negative pressure fan 9 is activated to generate suction, drawing the polishing debris into the negative pressure chamber 6 through the suction hole 7. The debris then flows with the airflow into the collection pipe 8, and finally tangentially into the primary separation cylinder 5. The airflow containing debris rotates downwards at high speed along the inner wall of the primary separation cylinder 5, forming a main vortex. Larger particles experience significant centrifugal force and are thrown against the inner wall of the primary separation cylinder 5, flowing downwards and finally exiting through the bottom outlet into the coarse waste collection box 2. Simultaneously, the piezoelectric ceramic actuator 10 is activated, applying 20-50... At a high-frequency alternating voltage of kHz, the piezoelectric ceramic actuator 10 generates rapid radial expansion and contraction vibrations. This high-frequency vibration pushes the surrounding air, exciting a high-intensity, high-frequency acoustic field in the top central region of the first-stage separation cylinder 5. This acoustic field interacts with the main vortex, forming a strong velocity shear and turbulence disturbance zone in the upper part of the first-stage separation cylinder 5. The equivalent effect of this disturbance zone is to generate a reverse momentum impact on the main vortex, thus forming a reverse vortex. When the main vortex and the reverse vortex meet, this region generates extremely high velocity shear gradients and turbulence intensity. For large particles, their inertia is large, and under the impact of violent reverse airflow and sudden changes in direction, they cannot follow the streamline, thus resulting in strong inertial collisions and turbulence. The diffusion of the flow and the rapid dissipation of kinetic energy can accelerate the settling of particles toward the wall. For fine particles and air, their inertia is small, making it easier to follow the complex composite streamline motion. Under the disturbance of the reverse vortex and the agglomeration effect of the sound wave, some fine particles are pushed into the strong centrifugal zone on the periphery of the main vortex, or are separated after agglomeration. However, most submicron-sized fine particles will flow upward with the inner swirling flow in the central area of ​​the first-stage separation cylinder 5 into the exhaust pipe 12, and then enter the second-stage separation cylinder 11 from the exhaust pipe 12. This allows the waste generated from grinding aluminum alloy cookware to be classified and recycled according to its coarseness, avoiding the increase in flux consumption, prolonged smelting time, and increased energy consumption in the waste during remelting, thus increasing the processing cost.

[0046] The airflow containing fine dust entering the secondary separation cylinder 11 flows upward. When it passes through the vortex formed by multiple circularly arranged inclined blades 18, the airflow is forced to rotate by the blades 18, forming a secondary vortex and generating centrifugal force. This centrifugal force pre-concentrates the dust in space to the inner wall area of ​​the secondary separation cylinder 11, significantly increasing the probability of fine particles entering the effective range of the subsequent electrostatic field. Simultaneously, the external power supply is activated, energizing the conductive sleeve 15, which in turn energizes the rotating shaft 17 and the blades 18. Because the edges of the blades 18 are serrated and have sharp points, tip discharge is formed, resulting in extremely high electric field strength at the edges of the blades 18. This ionizes the surrounding gas molecules, generating a large number of positive and negative ions. When the airflow carrying fine particles passes through... At that time, fine particles collide with ions and are charged within microseconds. The grounded metal dust collection cylinder 19 forms a strong radial non-uniform electric field with the high-voltage blades 18. The charged fine particles move towards the wall of the metal dust collection cylinder 19 under the drive of centrifugal force, while being attracted by a strong Coulomb force. The fine particles are firmly adsorbed on the inner wall of the metal dust collection cylinder 19, achieving efficient collection of fine dust. By periodically activating the electromagnetic vibrator 28 to strike the secondary separation cylinder 11, the fine dust layer attached to the inner wall of the metal dust collection cylinder 19 will fall into the receiving rack 20. Then, the fine dust will enter the fine waste recycling box 3 through the discharge pipe 22 for collection. Finally, the clean air will be discharged through the exhaust port 29 above.

[0047] In addition, when waste enters the collection pipe 8, the light scattering sensor 27 can monitor the dust concentration. When the dust concentration in the monitored airflow is high, the light scattering sensor 27 will send a signal, which will control the micro servo motor 24 to rotate forward through the PLC control circuit, driving the helical gear ring 25 to rotate forward, which in turn drives the helical gear 26 to rotate forward, thereby driving the rotating shaft 17 to rotate forward. This increases the opening angle between the multiple blades 18. At this time, the airflow passing through the blades 18 will generate a stronger vortex, which in turn generates a stronger centrifugal force. The greater centrifugal force can disperse more and finer particles. The particulate matter is thrown towards the cylinder wall area, which enables the dust to be more effectively concentrated in space before entering the electrostatic area, reducing the burden on the subsequent electrostatic field. When the light scattering sensor 27 detects that the dust concentration is low, the micro servo motor 24 will reverse, which will reduce the opening angle between the blades 18. The airflow passing through the blades 18 will generate a smaller vortex, thereby reducing the system energy consumption, improving the electrostatic collection efficiency, and thus reducing the noise of the entire system during operation. Therefore, by monitoring the dust concentration and automatically adjusting the angle of the blades 18, a dynamic optimal balance can be achieved between energy efficiency and collection efficiency.
