Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment devices, and in particular to a paint spraying waste gas treatment device. Background Technology

[0002] The paint spraying process releases volatile organic compounds (VOCs) and other harmful substances. If these exhaust gases are discharged directly into the atmosphere without treatment, they will harm the environment and human health. Therefore, it is essential to use a paint spraying exhaust gas treatment device.

[0003] A common method for treating exhaust gas is a combination of "pre-filtration + adsorption," using filters and activated carbon, particularly effective for spray painting exhaust containing paint mist, particulate matter, and volatile organic compounds (VOCs). However, when using filters, the large number of impurities in the exhaust easily clog the filters. Cleaning these particles can contaminate the ventilation pipes, and some particles may stubbornly adhere to the filters, making them difficult to remove with a brush. Therefore, this paper proposes a paint spraying exhaust gas treatment device. Utility Model Content

When cleaning the impurity particles from the filter screen, the cleaned-off impurity particles easily contaminate the ventilation pipes, and some particles may stubbornly adhere to the filter screen and cannot be easily cleaned with a brush.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A paint spraying exhaust gas treatment device includes an air inlet pipe, a filter pipe fixedly connected to one side of the air inlet pipe, two limiting rails fixedly installed at equal intervals on the inner side of the filter pipe, a cleaning box fixedly connected to one side of the filter pipe, the lower ends of the two limiting rails fixedly installed in the cleaning box, a filter plate movably installed between the two limiting rails and disposed inside the filter pipe, a first mounting groove opened on one side of the filter pipe, a connecting plate fixedly connected to one side of the filter plate, a slide fixedly connected to the outer side of the connecting plate, a first motor fixedly installed on the inner side of the cleaning box, a screw fixedly connected to the lower output end of the first motor, the slide threadedly connected to the screw, a limiting sleeve movably installed on the outer side of the lower end of the screw, and the cleaning box fixedly connected to the lower part of the limiting sleeve.

A drive shaft is fixedly connected to one output end of the second motor, and a first bevel gear is fixedly connected to one end of the drive shaft.

[0008] Furthermore, a second bevel gear is toothed on one side of the first bevel gear, a first transmission rod is fixedly connected to one side of the second bevel gear, and the first transmission rod is movably sleeved on the cleaning box. A brush plate is fixedly connected to one end of the first transmission rod, and a first limiting plate is fixedly connected to the outside of the cleaning box. The first limiting plate is movably sleeved on the outside of the transmission shaft.

[0009] Furthermore, a first pulley is fixedly sleeved on the outer side of the drive shaft, a drive belt is wound around the outer side of the first pulley, a second pulley is wound around the inner side of the drive belt, a second drive rod is fixedly connected to the inner side of the second pulley, an impact block is fixedly connected to one end of the second drive rod, and a second limiting plate is fixedly connected to the outer side of the cleaning box, the second limiting plate being movably sleeved on the outer side of the second drive rod.

[0010] Furthermore, a third transmission rod is movably sleeved on the outer side of the cleaning box, an impact hammer is fixedly connected to one end of the inner side of the third transmission rod, a transmission plate is fixedly sleeved on the outer side of the third transmission rod, a spring is fixedly connected to the inner side of the transmission plate, and the inner side of the spring is fixedly connected to the inner wall of the cleaning box.

[0011] Furthermore, an activated carbon pipe is fixedly connected to one side of the filter pipe, and a control panel is fixedly connected to the outside of the cleaning box. The control panel is electrically connected to the first motor and the second motor.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model, through the setting of a limiting sleeve, can move the filter plate into the cleaning box for individual cleaning, reducing the risk of impurities re-entering the filter pipe and preventing impurities from clogging the filter plate again. The first motor is started, and the first motor drives the slide table via a screw. The slide table drives the filter plate via a connecting plate, and the filter plate moves along the limiting track into the cleaning box for individual cleaning. This design allows the filter plate to be moved into the cleaning box for individual cleaning, reducing the risk of impurities re-entering the filter pipe and preventing impurities from clogging the filter plate again.

[0014] 2. This utility model, through the installation of a transmission belt, can simultaneously drive the impact hammer to vibrate the filter plate during brushing, improving the cleaning effect on the filter plate. The second motor is activated, driving the transmission shaft to rotate. The transmission shaft, through the first bevel gear, the second bevel gear, and the first transmission rod, drives the brush plate to rotate. The brush plate cleans the surface of the filter plate during rotation. Simultaneously, the transmission shaft, through the first pulley, the transmission belt, and the second pulley, drives the second transmission rod to rotate. The second transmission rod drives the impact block to rotate, and the impact block strikes the third transmission rod during rotation. During the impact, the third transmission rod drives the impact hammer to strike the filter plate. Simultaneously, the third transmission rod, through the transmission plate, drives the spring to stretch. When there is no impact, the spring contracts, thereby resetting the third transmission rod. As the impact block rotates, reciprocating motion is achieved. This design allows the impact hammer to vibrate the filter plate simultaneously during brushing, improving the cleaning effect on the filter plate.

[0025] like Figures 1-4 , Figure 7 As shown, a paint spraying exhaust gas treatment device includes an air inlet pipe 1, a filter pipe 2 fixedly connected to one side of the air inlet pipe 1, two limiting rails 4 fixedly installed at equal intervals on the inner side of the filter pipe 2, a cleaning box 11 fixedly connected to one side of the filter pipe 2, the lower ends of the two limiting rails 4 fixedly installed in the cleaning box 11, a filter plate 5 movably installed between the two limiting rails 4 and the filter plate 5 is set in the filter pipe 2, a first mounting groove is opened on one side of the filter pipe 2, a connecting plate 6 is fixedly connected to one side of the filter plate 5, a slide table 7 is fixedly connected to the outer side of the connecting plate 6, a first motor 9 is fixedly installed on the inner side of the cleaning box 11, a screw 8 is fixedly connected to the lower output end of the first motor 9, the slide table 7 is threadedly connected to the screw 8, a limiting sleeve 10 is movably installed on the outer side of the lower end of the screw 8, and the cleaning box 11 is fixedly connected to the lower part of the limiting sleeve 10. By adopting the above technical solution, the first mounting groove is set between the two guide rails of the limiting rail 4 on one side, and the connecting plate 6 passes through the first mounting groove.

[0026] The limiting rail 4 is fixedly installed on the filter pipe 2 and passes through the filter pipe 2. The filter pipe 2 has a connecting groove between the two limiting rails 4, and the filter plate 5 can pass through the connecting groove.

[0027] The filter pipe 2 is equipped with a sealing strip to prevent exhaust gas from passing through the first installation slot and the connecting slot, thus preventing pollution.

[0028] A baffle is installed inside the cleaning box 11 to prevent impurities and particles cleaned off the filter plate 5 from affecting the movement of the screw 8 and the slide table 7;

[0029] The bottom of the cleaning box 11 is equipped with a sealed cabinet door that can be opened. When needed, the cabinet door can be opened to remove the impurity particles removed from the filter plate 5 inside the cleaning box 11.

[0030] like Figures 1-6 As shown, a mounting box 13 is fixedly connected to the outside of the cleaning box 11. A second motor 14 is fixedly installed inside the mounting box 13. A drive shaft 15 is fixedly connected to one output end of the second motor 14. A first bevel gear 17 is fixedly connected to one end of the drive shaft 15. By adopting the above technical solution, the drive shaft 15 can drive the first bevel gear 17 to rotate.

[0031] like Figures 1-6 As shown, a second bevel gear 18 is meshed on one side of the first bevel gear 17, and a first transmission rod 19 is fixedly connected to one side of the second bevel gear 18. The first transmission rod 19 is movably sleeved on the cleaning box 11, and a brush plate 20 is fixedly connected to one end of the first transmission rod 19. A first limiting plate is fixedly connected to the outside of the cleaning box 11, and the first limiting plate is movably sleeved on the outside of the transmission shaft 15. By adopting the above technical solution, a through hole is provided on the cleaning box 11, which can limit the first transmission rod 19 to only rotate and not to move in other directions. The first transmission rod 19 is inserted into the through hole, and the through hole can support the first transmission rod 19 without being affected by size, thereby realizing a stable meshing connection between the first bevel gear 17 and the second bevel gear 18.

[0032] The position of the brush plate 20 is designed so that when the filter plate 5 moves into the cleaning box 11, the brush plate 20 can contact the filter plate 5 to clean the surface of the filter plate 5.

[0033] like Figures 1-6 As shown, a first pulley 16 is fixedly sleeved on the outer side of the drive shaft 15, a drive belt 21 is wound around the outer side of the first pulley 16, a second pulley 22 is wound around the inner side of the drive belt 21, a second drive rod 23 is fixedly connected to the inner side of the second pulley 22, an impact block 24 is fixedly connected to one end of the second drive rod 23, and a second limiting plate is fixedly connected to the outer side of the cleaning box 11. The second limiting plate is movably sleeved on the outer side of the second drive rod 23. With this arrangement, a limiting mechanism is provided on the second limiting plate, which can limit the second drive rod 23 to only rotate and prevent it from moving in other directions.

[0034] The impact block 24 is provided with a protrusion, which can impact and push the third transmission rod 25 during the rotation of the impact block 24. The protrusion is made of wear-resistant and smooth material.

[0035] like Figures 1-6As shown, a third transmission rod 25 is movably sleeved on the outer side of the cleaning box 11. An impact hammer 28 is fixedly connected to one end of the inner side of the third transmission rod 25. A transmission plate 27 is fixedly sleeved on the outer side of the third transmission rod 25. A spring 26 is fixedly connected to the inner side of the transmission plate 27. The inner side of the spring 26 is fixedly connected to the inner wall of the cleaning box 11. With this arrangement, a limit mechanism is provided on the cleaning box 11, which can limit the third transmission rod 25 to only rotate and prevent it from moving in other directions.

[0036] Furthermore, the overall structure of the cleaning box 11 is "L" shaped;

[0037] The position of the impact hammer 28 is set so that when the filter plate 5 is installed in the cleaning box 11, the impact hammer 28 is located on one side of the filter plate 5, and the impact hammer 28 can impact the filter plate 5 as pushed by the third transmission rod 25.

[0038] The impact hammer 28 is equipped with a designed shock absorption device, which can cause the filter plate 5 to vibrate when it impacts the filter plate 5 without damaging the filter plate 5.

[0039] like Figures 1-7 As shown, an activated carbon pipe 3 is fixedly connected to one side of the filter pipe 2, and a control panel 12 is fixedly connected to the outside of the cleaning box 11. The control panel 12 is electrically connected to the first motor 9 and the second motor 14. With this setup, the exhaust gas passing through the filter pipe 2 will enter the activated carbon pipe 3 for treatment, and then enter other areas.

[0040] It should be noted that during use, an external power supply is connected through the control panel 12, and exhaust gas is injected through the air inlet pipe 1. The exhaust gas then enters the filter pipe 2, is filtered by the filter plate 5, and then enters the activated carbon pipe 3 for further treatment.

[0041] When it is necessary to clean the surface of the filter plate 5, start the first motor 9. The first motor 9 drives the slide table 7 to move through the screw 8. The slide table 7 drives the filter plate 5 to move through the connecting plate 6. The filter plate 5 moves along the limit track 4 into the cleaning box 11. The filter plate 5 is cleaned separately in the cleaning box 11. The reverse operation can reset the filter plate 5.

[0042] The second motor 14 is started, which drives the transmission shaft 15 to rotate. The transmission shaft 15 drives the brush plate 20 to rotate through the first bevel gear 17, the second bevel gear 18 and the first transmission rod 19. The brush plate 20 cleans the surface of the filter plate 5 during rotation. At the same time, the transmission shaft 15 drives the second transmission rod 23 to rotate through the first pulley 16, the transmission belt 21 and the second pulley 22. The second transmission rod 23 drives the impact block 24 to rotate. The impact block 24 impacts the third transmission rod 25 during rotation. During the impact, the third transmission rod 25 drives the impact hammer 28 to impact the filter plate 5. At the same time, the third transmission rod 25 drives the spring 26 to stretch through the transmission plate 27. When there is no impact, the spring 26 contracts and drives the third transmission rod 25 to reset. As the impact block 24 rotates, reciprocating motion is achieved. The filter plate 5 is continuously vibrated by the impact and its surface is cleaned by the brush plate 20, thereby cleaning the surface of the filter plate 5.

[0043] This utility model provides a paint spraying exhaust gas treatment device, which solves the problem that when using a filter screen to treat exhaust gas, the exhaust gas contains a large number of impurity particles that easily clog the filter screen. When cleaning the impurity particles from the filter screen, the cleaned-off impurity particles can easily contaminate the ventilation pipes. Some particles may be stubbornly attached to the filter screen and cannot be easily cleaned with a brush. This device is quite practical.
