[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0035] Please see the appendix Figure 1-3This invention provides an industrial degreasing and dust removal device, including a base plate 1. Two filter sections are arranged side-by-side along a first direction on the base plate 1, and two flow guide sections are arranged side-by-side along a second direction on each of the filter sections. An electrical box 13 is mounted on the base plate 1, and a battery is installed inside the electrical box 13 to provide power to the various electrical components. A controller 14 is mounted on a fixed plate 5 on the cylinder, and the controller 14 is connected to the electrical box 13. The first direction in this application is the front-to-back direction, and the second direction is the left-to-right direction. Each filter section is equipped with two flow guide sections, ensuring both the compactness of the device structure and the independent use of each flow guide section. The controller 14 is a conventional PLC controller. The electrical box 13 and the controller 14 serve as conventional power distribution facilities, enabling control of the entire device's operating status through the controller 14 and allowing the user to determine the device's operating status by observing the controller 14. The PLC is equipped with a display screen, allowing the user to issue different operation commands via the touch screen.
[0036] Specifically, please refer to the appendix. Figure 4-5 The filtration unit includes a storage box 2, a lower fixing plate 3, an outlet filter 4, an upper fixing plate 5, a primary filter 8, and a secondary filter 9. The lower fixing plate 3 is located on top of the storage box 2, and the outlet filter 4 is located on top of the lower fixing plate 3. The outlet filter 4 has air outlets from its side and is used to adsorb smoke particles in the flue gas. The upper fixing plate 5 is located on top of the outlet filter 4, and the secondary filter 9 is located inside the storage box 2, with its top extending to the lower surface of the lower fixing plate 3. The secondary filter 9 has air outlets from its bottom and side. In this application, the outlet filter 4 is a sintered metal mesh or an activated carbon filter. The special material of the outlet filter 4 adsorbs smoke particles in the flue gas, preventing smoke particles from flowing back into the air. The secondary filter 9 can also be a sintered metal mesh to enhance the filtration effect.
[0037] It should be noted that the mesh size of the primary filter 8 in this application is larger than that of the secondary filter 9. The primary filter 8 in this application mainly isolates larger impurities such as iron filings attached to the surface of the workpiece, so an ordinary metal filter can be used instead of expensive materials, thus reducing costs.
[0038] Specifically, please refer to the appendix. Figure 4-5 The flow guide includes a cylinder 6, a hopper 7, and a fan system 10. The cylinder 6 extends from top to bottom through the upper fixing plate 5 and the lower fixing plate 3 and into the secondary filter 9. The hopper 7 is located at the top of the cylinder 6, and the primary filter 8 is located at the top of the hopper 7. The fan system 10 is located inside the cylinder 6 and is used to create negative pressure inside the cylinder 6 while collecting energy. In this application, the hopper 7 has an upper circular structure and a lower circular structure, which minimizes the gap between the tops of the four hoppers 7, providing a maximum operating platform for welding operations. At the same time, the bottoms of the four hoppers 7 can be directly inserted into the four cylinders 6, which is convenient for disassembly and assembly.
[0039] The secondary filter 9 and the cylinder 6 form a first filtration space, and the exhaust filter 4 and the cylinder 6 form a second filtration space. The lower fixed plate 3 of the cylinder is provided with a guide hole 301, which connects the first filtration space and the second filtration space. In use, depending on the size or quantity of the workpiece, the workpiece is placed on one or two primary filters 8, and one or more fan systems 10 are selected to participate in the operation, so that negative pressure is generated in the hopper 7. The oil stains on the workpiece and the welding fumes flow downward through the hopper 7 and the cylinder 6 under the action of negative pressure and enter the first filtration space. The oil stains fall from the bottom of the secondary filter 9 into the storage box 2 under the action of gravity. The fumes flow upward in the opposite direction after passing through the first filtration space and enter the second filtration space through the guide hole 301. Finally, the smoke particles are filtered from the side of the exhaust filter 4 and discharged from the equipment.
[0040] To ensure the airtightness of the air outlet filter 4, sealing rings are respectively installed between the lower fixing plate 3 of the cylinder and the air outlet filter 4, between the upper fixing plate 5 of the cylinder and the air outlet filter 4, between the lower fixing plate 3 of the cylinder and the cylinder 6, and between the upper fixing plate 5 of the cylinder and the cylinder 6.
[0041] This application effectively extends the entire filtration path, achieving the purpose of oil and dust removal through three filtrations. Compared with existing oil and dust removal equipment, it has a more compact structure, controllable airflow, avoids resource waste, centrally treats oil pollution, purifies the environment, and the equipment is more in line with the new concept of energy conservation and environmental protection.
[0042] Please refer to the appendix in this application. Figure 5-6 The fan system 10 includes a first retainer 1001, a second retainer 1002, a pneumatic motor 1003, a motor output shaft 1005, an impeller 1006, and a generator 1007.
[0043] The first retainer 1001 and the second retainer 1002 are spaced apart from top to bottom on the inner wall of the cylinder 6. The pneumatic motor 1003 is mounted on the first retainer 1001. The motor output shaft 1005 is mounted on the output end of the pneumatic motor 1003 and is coaxially arranged with the cylinder 6. The other end of the motor output shaft 1005 is connected to one end of the central hole of the impeller 1006. The generator 1007 is mounted on the second retainer 1002. The input end of the generator 1007 is connected to the other end of the central hole of the impeller 1006. In this application, the generator 1003 is electrically connected to the battery in the electrical box. When the pneumatic motor 1004 drives the impeller 1006 to rotate, a negative pressure is generated inside the cylinder 6. The rotation of the impeller 1006 drives the input end of the generator 1007 to rotate, storing energy in the battery and completing energy recovery.
[0044] Specifically, the first retainer 1001 and the second retainer 1002 are respectively provided with multiple hollow parts so that the smoke can pass through the first retainer 1001 and the second retainer 1002.
[0045] Please refer to the appendix in this application. Figure 6 To improve the starting safety of the pneumatic motor 1003, a pneumatic switch 1004 is eccentrically arranged inside the cylinder 6. The pneumatic switch 1004 is connected to the pneumatic motor 1003 through a bend 1009. The eccentrically arranged start switch 1004 is closer to the inner wall of the hopper 7, which not only makes it easier to fix, but also avoids impurities from entering the hopper 7 under negative pressure as much as possible.
[0046] A coupling 1008 is provided between the other end of the central hole of the impeller 1006 and the generator 1007.
[0047] Please refer to the appendix in this application. Figure 2 and 6 The pneumatic switch 1004 has two first air inlet / outlet connection holes 1004a on its side, and the hopper 7 has a second air inlet / outlet connection hole 701 corresponding to the first air inlet / outlet connection holes 1004a on its side. The first air inlet / outlet connection holes 1004a and the second air inlet / outlet connection holes 701 are connected by pipe joints to facilitate air intake and exhaust of the pneumatic switch 1004. Furthermore, in order to better control the start of the pneumatic motor 1003, a solenoid valve is provided at the air inlet of the second air inlet / outlet connection hole 701. The solenoid valve is electrically connected to the electrical box 13 and the controller 14 respectively. When the solenoid valve is opened, the pneumatic switch 1004 drives the pneumatic motor 1003 to work.
[0048] Please refer to the appendix in this application. Figure 1 To facilitate the assembly and disassembly of the cylinder 6 and the secondary filter 9, multiple cylinder fixing brackets 11 are evenly connected between the outer surface of the cylinder 6 and the upper surface of the upper fixing plate 5 of the cylinder; a positioning groove is provided at the bottom of the lower fixing plate 3 of the cylinder, and the top of the secondary filter 9 is inserted into the positioning groove; specifically, the cylinder fixing bracket 11 has an L-shaped structure, so that the cylinder 6 is installed perpendicular to the upper fixing plate 5 of the cylinder when it is installed.
[0049] Please refer to the appendix in this application. Figure 2 An oil trough 501 is recessed on the upper surface of the fixed plate 5 on the cylinder body, and an oil leakage hole 502 is provided on the fixed plate 5 on the cylinder body. The oil leakage hole 502 connects the oil trough 501 and the second filtration space. When oil stains fall from the gap between the hoppers 7 onto the fixed plate 5 on the cylinder body, they can pass through the oil leakage hole 502 into the second filtration space, and then pass through the bottom of the secondary filter screen 9 into the storage box 2.
[0050] Please refer to the appendix in this application. Figure 2A pressure sensor 702 is installed on the inner wall of the hopper 7. The top of the pressure sensor 702 is in contact with the primary filter screen 8. The pressure sensor 702 is electrically connected to the electrical box. When a workpiece is placed on the primary filter screen 8, the pressure sensor 702 senses the workpiece and feeds the signal back to the controller 14. The controller 14 controls the solenoid valve to open, and the pneumatic motor 1003 starts immediately.
[0051] Please refer to the appendix in this application. Figure 1 The secondary filter 9 is equipped with a liquid level sensor (not shown in the figure) and a flow sensor. An oil pump 12 is installed on the base plate 1, and an oil drain hole 201 is provided on the side of the storage tank 2. The input end of the oil pump 12 is connected to the oil drain hole 201. The liquid level sensor and the oil pump 12 are electrically connected to the controller 14. The liquid level sensor provides feedback on the oil level in the storage tank 2, and controls the oil pump 12 to work, so as to discharge the oil in the storage tank 2 through the oil drain hole 201, thereby achieving the purpose of cleaning the oil. The flow sensor provides feedback on the flow rate. When the flow rate is less than the set value, it indicates that the secondary filter 9 is blocked. At this time, the flow sensor sends a signal to facilitate timely replacement of the secondary filter 9.
[0052] To facilitate the movement and transportation of this equipment within the welding workshop, casters 15 are provided at the bottom of the base plate 1.

[0055] The liquid level sensor monitors the liquid level in the oil storage tank 2. When the warning liquid level is reached, the oil pump 12 will pump out the oil from the storage tank 2.
[0056] When a large amount of welding slag and impurities fall onto the secondary filter 9 and affect the airflow, the flow sensor inside the secondary filter 9 sends a signal to prompt the replacement or cleaning of the secondary filter 9; or the pressure sensor inside the hopper 7 monitors the negative pressure value and determines the magnitude of the negative pressure value within the normal range. When the negative pressure warning value is reached, an alarm will also be triggered to prompt the replacement or cleaning of the secondary filter 9.
