Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, specifically to an environmentally friendly waste gas treatment device for spray painting equipment. Background Technology

[0002] Spray painting equipment is a specialized industrial tool used to uniformly spray paint onto metal or non-metal surfaces to achieve a protective or decorative layer. Waste gas treatment devices are environmental protection systems specifically designed to collect and purify harmful gases and particulate matter generated during the spray painting process, ensuring they meet national emission standards.

[0003] Currently, the conventional process for treating exhaust gas generated by painting equipment involves first using filter cotton to intercept and filter paint mist particles in the exhaust gas, and then using activated carbon to adsorb and remove organic harmful gases in the exhaust gas. This treatment method is widely used because of its simple structure and low cost. However, in actual use, both filter cotton and activated carbon are consumables that are easily saturated. When they are saturated, they need to be manually removed and replaced with new consumables. This not only involves frequent maintenance operations and cumbersome procedures, but also results in high manpower consumption and high maintenance costs, making it difficult to meet the needs of continuous and efficient exhaust gas treatment.

[0007] Furthermore, filter holes are provided on the surfaces of both the outer and inner support cylinders, and the axes of the outer and inner support cylinders coincide.

[0008] Furthermore, the conveying blade is spiral-shaped and slidably connected to the outer support cylinder.

[0009] Furthermore, the plug is conical, and the axis of the plug coincides with the axis of the discharge hole.

[0010] Furthermore, the replacement component includes a second bevel gear set.

A guide rod seat is slidably connected to one side of the sliding frame, and a compression spring is provided on one side of the guide rod seat. A side box is placed on the top of the guide rod seat. A rubber-coated roller is fixedly connected to the upper outer side of the gear shaft. A fixed shaft is rotatably connected to the middle of the side box, and a take-up roller is placed on the outer side of the fixed shaft. A second damping shaft is rotatably connected inside the side box, and an unwinding roller is provided on the outer side of the second damping shaft. Limit rollers are symmetrically arranged at one end of the middle of the side box.

[0011] Furthermore, the central part of the synchronous shaft is prismatic, and the synchronous shaft is rotatably connected to the guide rod seat.

[0012] Furthermore, the sliding frame is rotatably connected to the bevel gear sleeve, and the sliding frame is slidably connected to the side box.

[0013] Furthermore, a limiting plate is fixedly connected to the bottom of the side box, and a pulley rod is slidably connected to the middle of the limiting plate.

[0015] This invention provides an environmentally friendly waste gas treatment device for spray painting equipment, which has the following beneficial effects: 1. After the device is started, the present invention can form a stable negative pressure inside to efficiently draw in waste gas. The waste gas passes through the filter cotton belt to intercept sticky paint mist and activated carbon particles to adsorb harmful gases. When it is necessary to replace the activated carbon particles, the adsorption chamber can be driven to rotate through the linkage structure, so that the ineffective activated carbon is automatically and directionally discharged to the collection box under the push of the internal blades. After discharge, the discharge port is automatically sealed to prevent the loss of effective filler. This process can realize the automatic replacement of activated carbon and waste collection without manual disassembly. At the same time, the rotation action can also disperse the activated carbon in the storage tank to avoid arching and ensure stable and continuous adsorption effect.

[0016] 2. This invention enables simultaneous and stable winding of saturated filter tape and unwinding of new filter tape while operating activated carbon. The constant pressure clamping structure ensures no slippage during winding, while the constant tension unwinding structure ensures the filter tape remains taut. Furthermore, the design uses a rubber-coated roller with a fixed outer diameter for winding, ensuring a precise and constant length of filter tape for each replacement. This effectively avoids length errors caused by variations in the diameter of the winding roller, preventing material waste and ensuring effective filter tape replacement, thus improving utilization and replacement accuracy.

[0017] 3. In this invention, the activated carbon discharge, new activated carbon replenishment, filter cotton belt winding and unwinding, and the opening and closing of the pressing mechanism are all controlled by a single motor through mechanical structures such as cams and gear sets. During the replacement process, each component can automatically connect according to a preset sequence. First, the filter cotton belt pressing mechanism is released synchronously, then the waste discharge and new filter cotton belt replacement actions are performed in a coordinated manner, and finally the filter cotton belt is automatically re-pressed to ensure that it fits tightly with the outer cylinder without gaps. The entire process is achieved by pure mechanical linkage without the need for an additional power source, which greatly simplifies the structure, reduces costs, and improves the synchronization, stability, and ease of operation of the device.

[0020] Please see Figures 1 to 5This invention provides a technical solution: an environmentally friendly waste gas treatment device for spray painting equipment, comprising a housing 1 and a conveying assembly 6. An exhaust pipe 2 is installed on the outer side of the housing 1, and an outer support cylinder 3 is fixedly connected inside the housing 1. A storage tank 4 is installed on the top of the outer support cylinder 3, and a fan 5 is connected to the top of the storage tank 4. The conveying assembly 6 is located at the bottom of the housing 1 and includes a motor 601. The motor 601 is installed at the bottom of the housing 1, and a cam 602 is connected to the output end of the motor 601. A toothed gear ring 603 is fixedly connected to the bottom of the cam 602. A hanging plate 604 is fixedly connected to the bottom of the housing 1, and a first damping shaft 605 is rotatably connected inside the hanging plate 604. A drive gear 606 is installed on the outer side of the middle part of the first damping shaft 605, and a first bevel gear set 607 is provided at one end of the first damping shaft 605. An inner support cylinder 608 is connected to the top of the first bevel gear set 607. A conveying blade 609 is fixedly connected to the outer side of the outer support cylinder 608. The housing 1 is rotatably connected to the inner support cylinder 608, and the inner support cylinder 608 is rotatably connected to the storage tank 4. Filter holes are provided on the surfaces of both the outer support cylinder 3 and the inner support cylinder 608, and the axes of the outer support cylinder 3 and the inner support cylinder 608 coincide. The conveying blade 609 is spiral-shaped and slidably connected to the outer support cylinder 3. A dispersing rod 610 is provided on the upper outer side of the inner support cylinder 608, and a discharge hole is provided at the bottom of the housing 1. 611, and a hanging seat 612 is installed at the bottom of the housing 1, a spring seat 613 is installed at the top of the hanging seat 612, and a plug 614 is fixedly connected to the top of the spring seat 613. The plug 614 is conical, and the axis of the plug 614 coincides with the axis of the discharge hole 611. A waste box 615 is installed at the bottom of the housing 1. A replacement component 7 is connected to one end of the first damping shaft 605, and a clamping component 8 is installed above the middle of the first damping shaft 605. The specific operation is as follows: After starting the fan 5, a stable negative pressure is formed inside the inner support cylinder 608. Relying on the negative pressure suction, the exhaust gas generated by the painting equipment can be continuously and efficiently drawn through the exhaust pipe 2. At this time, when the exhaust gas enters the housing 1, the filter cotton belt wrapped on the outside of the outer support cylinder 3 can fully intercept and adsorb the sticky paint mist particles in the exhaust gas. Then the exhaust gas will enter the adsorption cavity between the outer support cylinder 3 and the inner support cylinder 608. The activated carbon particles arranged in the middle can fully adsorb the organic harmful gases in the exhaust gas, greatly improving the exhaust gas purification effect. The purified clean gas is discharged from the equipment with the fan 5. When it is necessary to replace the activated carbon particles, the motor 601 is started to drive the toothed ring 603 under the cam 602 to rotate one revolution. When the toothed ring 603 meshes with the drive gear 606, it can drive the first damping shaft 605 to rotate, and then drive the inner support cylinder 608 to rotate through the first bevel gear set 607, so that the conveying blade 609 can directionally downwards the activated carbon particles during the rotation. The conveying process generates a continuous downward thrust, which pushes the plug 614 downward under the compression of the activated carbon particles. The exhausted activated carbon can then be automatically discharged through the discharge hole 611 into the waste bin 615 for centralized collection, eliminating the need for frequent manual replacement. When the conveying stops, the spring seat 613 will push the plug 614 to quickly close the discharge hole 611 under the limit of the hanging seat 612, preventing the activated carbon above from falling and being lost, which would lead to insufficient filler in the adsorption chamber and ensure that the subsequent waste gas filtration and adsorption effect is stable and meets the standards. In addition, during the rotation of the inner support cylinder 608, it can also drive the dispersing rod 610 to continuously stir the activated carbon particles in the storage tank 4, effectively breaking up the clumps of material and preventing arching and jamming during subsequent conveying, ensuring smooth discharge of activated carbon. Therefore, there is no need to frequently disassemble and replace the internal filter element manually, which greatly reduces the labor intensity of the users, while improving the continuity and stability of the overall operation of the device and reducing the frequency of maintenance downtime.

[0021] Please see Figure 2 , Figure 3 and Figure 6The replacement component 7 includes a second bevel gear set 701. One end of the first damping shaft 605 is provided with the second bevel gear set 701, and one end of the second bevel gear set 701 is connected to a synchronous shaft 702. A bevel gear sleeve 703 is slidably connected to the outer side of the synchronous shaft 702, and a gear shaft 704 meshes with the top of the bevel gear sleeve 703. A sliding frame 705 is rotatably connected to the outer side of the gear shaft 704, and the sliding frame 705 is rotatably connected to the bevel gear sleeve 703. A guide rod seat 706 is slidably connected to one side of the sliding frame 705, and a compression spring 707 is provided on one side of the guide rod seat 706. The middle part of the synchronous shaft 702 is prismatic. Furthermore, the synchronous shaft 702 is rotatably connected to the guide rod seat 706, the top of the guide rod seat 706 is provided with a side box 708, the sliding frame 705 is rotatably connected to the bevel gear sleeve 703, and the sliding frame 705 is slidably connected to the side box 708. The upper outer side of the gear shaft 704 is fixedly connected with a rubber-coated roller 709, the middle of the side box 708 is rotatably connected with a fixed shaft 710, and the outer side of the fixed shaft 710 is provided with a take-up roller 711. The inside of the side box 708 is rotatably connected with a second damping shaft 712, and the outer side of the second damping shaft 712 is provided with an unwinding roller 713. The middle end of the side box 708 is symmetrically provided with limit rollers 714. The specific operation is as follows: During the rotation of the first damping shaft 605, the second bevel gear set 701 will also cause the synchronous shaft 702 to rotate synchronously. This, in turn, will drive the rubber-coated roller 709 to rotate stably via the bevel gear sleeve 703 and gear shaft 704. At this time, the compression spring 707 will continuously push the sliding frame 705 under the limit of the guide rod seat 706, ensuring that the rubber-coated roller 709 always presses tightly against the filter cotton belt on the take-up roller 711. This effectively increases the contact friction between the filter cotton belt and the take-up roller 711 and the rubber-coated roller 709, preventing slippage and free rotation during the winding process. Therefore, when the rubber-coated roller 709 rotates, it can stably drive the take-up roller 711 to wind up the saturated filter cotton belt. At this time, the second damping shaft 712 will provide a constant damping tension to the unwind roller 713, allowing the unwind roller 713 to synchronously unwind new filter cotton belt. Throughout the process, the filter cotton belt is kept taut to prevent it from becoming too loose. This prevents wrinkles from affecting the tightness of the fit between the filter cotton belt and the outer support cylinder 3 during subsequent wrapping, thus ensuring a stable paint mist filtration effect. This allows for fully automatic winding and replacement of the filter cotton belt on the outside of the outer support cylinder 3, eliminating the need for frequent manual disassembly and assembly. Furthermore, the rotation of the rubber-coated roller 709 is used to wind the filter cotton belt. Since its outer diameter remains constant, the number of rotations per cycle is fixed, allowing for precise control of the length of the filter cotton belt to be changed each time. This prevents excessive deviations in the length of a single winding due to the increased thickness of the stacked filter cotton belt on the outside of the winding roller 711 and the gradual increase in the roll diameter. This avoids wasting filter cotton belt material due to excessive winding and also prevents winding too short, which would prevent effective replacement. This improves the utilization rate and replacement accuracy of the filter cotton belt.

[0022] Please see Figure 3and Figure 7 The bottom of the side box 708 is fixedly connected to a limiting plate 801, and a pulley rod 802 is slidably connected to the middle of the limiting plate 801. A drive column 803 is installed on the top surface of the middle of the pulley rod 802, and a slotted plate 804 is slidably connected to the outer side of the drive column 803. A torsion spring shaft 805 is provided at one end of the slotted plate 804, and a pressure plate 806 is provided on the upper outer side of the torsion spring shaft 805. Fastening straps 807 are connected to both the upper and lower ends of the pressure plate 806, and a lifting rope 808 is provided in the middle of the fastening strap 807. The lifting rope 808 is fixedly connected to the housing 1, and the housing 1 is rotatably connected to the torsion spring shaft 805. The specific operation is as follows: When replacing the filter cotton belt, when the convex part on the cam 602 driven by the motor 601 moves away from the pulley rod 802, the torsion spring shaft 805 will automatically rotate under the elastic reset action of its own torsion spring. Its lower end will smoothly drive the pulley rod 802 to move towards the cam 602 through the slotted plate 804 and the drive column 803, while its upper end will simultaneously drive the pressure plate 806 to loosen the filter cotton belt. At the same time, the fastening belt 807 will also loosen the upper and lower sides of the filter cotton belt, and the middle part of the fastening belt 807 will be flexibly limited by the suspension rope 808 to prevent it from falling too much and shifting when it is loosened. Subsequently, the toothed ring 603 at the bottom of the cam 602 will mesh with the drive gear 606, synchronously controlling the conveying component 6 and the replacement component 7 to complete the linkage action of waste material discharge and new material replacement. After the replacement is completed, when the toothed ring 603 separates from the drive gear 606, the damping of the first damping shaft 605 will be activated. The limiting performance effectively maintains the static stability of the first damping shaft 605, preventing inertial movement of components. Subsequently, the convex part of the cam 602 pushes the pulley rod 802 again, causing it to slide directionally inside the limiting plate 801. It then pushes the slotted plate 804 through the drive column 803, thereby causing the torsion spring shaft 805 to rotate precisely and reset, evenly pressing the filter cotton belt onto the outside of the outer support cylinder 3. At this time, the pressure plate 806 also simultaneously pulls the fastening belt 807, ensuring that both the upper and lower ends of the filter cotton belt are tightly fitted to the outer support cylinder 3, eliminating the problem of paint mist escape due to air leakage from gaps, and thus continuously maintaining the stable filtration effect of the device. Therefore, in the entire process of replacing the filter cotton belt, all actions are driven by a single motor 601 to achieve mechanical linkage, without the need for additional electric or pneumatic drive sources. This simplifies the device structure, reduces equipment costs, and makes operation and use more convenient and reliable, while also improving the synchronization and stability of the device operation.

[0023] In summary, this environmentally friendly waste gas treatment device for spray painting equipment is used as follows: First, after the fan 5 is started by the controller, a stable negative pressure is formed inside the inner support cylinder 608. Relying on the negative pressure suction, the exhaust gas generated by the painting equipment can be continuously and efficiently sucked through the exhaust pipe 2. When the exhaust gas enters the housing 1, the filter cotton belt wrapped on the outside of the outer support cylinder 3 can fully intercept and adsorb the sticky paint mist particles in the exhaust gas. Then the exhaust gas will enter the adsorption chamber between the outer support cylinder 3 and the inner support cylinder 608. The activated carbon particles arranged in the middle fully adsorb the organic harmful gases in the exhaust gas, greatly improving the exhaust gas purification effect. The purified clean gas is discharged from the equipment with the fan 5. Secondly, when it is necessary to replace the activated carbon granules, the starting motor 601 drives the toothed ring 603 under the cam 602 to rotate one revolution. During this process, the protrusion on the cam 602 will move away from the pulley rod 802, and the torsion spring shaft 805 will automatically rotate under the elastic reset action of its own torsion spring. Its lower end will smoothly drive the pulley rod 802 to move towards the cam 602 through the slotted plate 804 and the drive column 803, while its upper end will simultaneously drive the pressure plate 806 to loosen the filter cotton belt. At the same time, the fastening belt 807 will also loosen the upper and lower sides of the filter cotton belt, and the middle part of the fastening belt 807 will be flexibly limited by the hanging rope 808 to prevent it from falling too much and shifting when it is loose. Next, the toothed gear ring 603 at the bottom of the cam 602 meshes with the drive gear 606, driving the first damping shaft 605 to rotate. This, in turn, drives the inner support cylinder 608 to rotate via the first bevel gear set 607. This allows the conveying blade 609 to directionally convey the activated carbon particles downwards during rotation, generating a continuous downward thrust. Therefore, under the pressure of the activated carbon particles, the plug 614 is pushed downwards, and the degraded activated carbon is automatically discharged through the discharge hole 611 into the waste bin 615 for centralized collection, eliminating the need for frequent manual replacement. Afterwards, when conveying stops, the spring seat 6... 13 will push the plug 614 to quickly seal the discharge hole 611 under the limit of the hanging seat 612, so as to prevent the activated carbon above from falling and losing, resulting in insufficient filling of the adsorption chamber, and ensuring that the subsequent waste gas filtration and adsorption effect is stable and meets the standard. In addition, during the rotation of the inner support cylinder 608, it can also drive the dispersing rod 610 to continuously stir the activated carbon particles in the storage tank 4, effectively breaking up the clumps of material, preventing arching and jamming during subsequent conveying, and ensuring smooth discharge of activated carbon. Therefore, there is no need to frequently disassemble and replace the internal filter element manually, which greatly reduces the labor intensity of the user. Then, during the rotation of the first damping shaft 605, the second bevel gear set 701 will cause the synchronous shaft 702 to rotate synchronously, which in turn will drive the rubber-coated roller 709 to rotate stably through the bevel gear sleeve 703 and the gear shaft 704. At this time, the compression spring 707 will continue to push the sliding frame 705 under the limit of the guide rod seat 706, so that the rubber-coated roller 709 always presses the filter cotton belt on the take-up roller 711, effectively increasing the contact friction between the filter cotton belt and the take-up roller 711 and the rubber-coated roller 709, preventing slippage and free rotation during the winding process. Therefore, when the rubber-coated roller 709 rotates, the rubber-coated roller 709 rotates. When the 9-axis rotates, it can stably drive the take-up roller 711 to take up the saturated filter cotton tape. At this time, the second damping shaft 712 will provide constant damping tension to the unwinding roller 713, so that the unwinding roller 713 keeps the filter cotton tape taut during the synchronous unwinding of the new filter cotton tape, avoiding the filter cotton tape being too loose, and preventing the loose wrinkles from affecting the tightness between it and the outer support cylinder 3 during subsequent wrapping, thereby ensuring that the paint mist filtration effect is always stable. Thus, the filter cotton tape on the outside of the outer support cylinder 3 can be automatically wound and replaced without frequent manual disassembly and assembly. Finally, after the replacement is completed, when the toothed ring 603 separates from the drive gear 606, the damping limiting performance of the first damping shaft 605 effectively maintains its static stability, preventing inertial movement of the components. Subsequently, the protrusion of the cam 602 pushes the pulley rod 802 again, causing it to slide directionally inside the limiting plate 801, and pushes the slotted plate 804 through the drive column 803, thereby causing the torsion spring shaft 805 to precisely rotate and reset, evenly pressing the filter cotton belt onto the outside of the outer support cylinder 3. At this time, the pressure plate 806 will also tighten the fastening belt 807 simultaneously, so that both the upper and lower ends of the filter cotton belt are tightly fitted with the outer support cylinder 3, eliminating the problem of paint mist escaping due to air leakage in the gaps, and thus continuously maintaining the stable filtration effect of the device. Therefore, in the entire process of replacing the filter cotton belt, all actions are driven by a single motor 601 to achieve mechanical linkage, without the need to add additional electric or pneumatic drive sources. This simplifies the device structure, reduces equipment costs, and makes operation and use more convenient and reliable, while also improving the synchronicity and stability of the device operation.
