Description

Technical Field

[0001] The present invention relates to the field of advanced environmental protection industries, and particularly to an environment-friendly air purification device for a production line for producing mildew-proof color-coated plates. Background Art

[0002] With the increasing demand for surface protection and decoration in the fields of construction, household appliances and industrial equipment, the production process of mildew-proof color-coated plates has been gradually popularized. In the production process of color-coated plates, the painting process is one of the key links. The exhaust gas containing paint mist, volatile organic compounds (VOCs) and heavy metal ions (such as lead, chromium, etc.) generated by it directly affects the workshop environment and the health of operators, and pollutes the atmosphere. Therefore, it is generally necessary to use a civil indoor air purifier to purify the air in the painting booth. In the prior art, an activated carbon adsorption device is mostly used to treat the exhaust gas in the painting booth as an air purification device in the production line for producing mildew-proof color-coated plates. However, the activated carbon in the traditional activated carbon purification device is prone to a rapid decline in adsorption performance due to pore blockage or chemical saturation, and usually needs to be replaced every 3-7 days, with high maintenance costs and affecting production continuity. Moreover, in the later stage of purification, due to the accumulation of more paint mist, volatile organic compounds and heavy metal ions on the activated carbon, it will affect the efficient adsorption of these harmful substances by the activated carbon, and then affect the air purification effect in the painting booth, resulting in unqualified purified air being discharged, still polluting the atmosphere and affecting the workshop environment and the health of operators.

[0014] The beneficial effects of the environment-friendly air purification device for the production line of the mildew-proof color-coated board provided by the present invention are as follows: 1. When the discharged clean gas passes through the first air bin, it will blow the first air wheel to rotate, and then drive the driving gear to rotate through the first driving shaft, and then drive the runner to rotate through the toothed ring. Thus, the air entering the purification bin can always be filtered by new activated carbon particles, ensuring that the filtered air can meet the emission standards, and avoiding the reduction of the efficiency of the activated carbon in filtering air after filtering air for a period of time, resulting in the emission of air not meeting the environmental protection emission standards.

[0015] 2. When the gas passes through the second air bin, the second air wheel drives the third driving shaft to rotate. Then, through the cooperation of the cam and the spring rod, the screen is driven to rotate up and down, so that the activated carbon can be evenly spread on the upper end of the screen and conveyed to the right, enabling the used activated carbon to be completely restored. Moreover, the third driving shaft synchronously drives the fourth belt wheel to rotate through the third belt wheel and the second transmission belt, and then drives the conveying belt to rotate through the cooperation with the driven roller, so that the restored activated carbon can be conveyed back to the purification bin again.

[0016] 3. When the discharge pipe rotates to the vertical state, that is, when the discharge pipe blocks the upper opening of the heating bin, the activated carbon particles no longer fall at this time. At the same time, the worm drives the turbine to rotate, so that the gas inside the fourth connecting pipe no longer enters, and the other ventilation hole rotates to the lower end of the fifth connecting pipe, allowing the high-temperature and high-pressure gas to enter the sixth connecting pipe. At the same time, the fan is started to blow hot air to the activated carbon particles between the conveying belt and the feeding bin, so that the activated carbon particles are dried before entering the purification bin. Thus, the used activated carbon particles can be restored, dried and conveyed back to the runner inside the purification bin again, further reducing the possibility that the emission of air fails to meet the standards due to untimely manual replacement, and reducing the cost of using activated carbon particles.

[0017] 4. The cooled hot steam re-enters the spray pipe network through the sixth connecting pipe to wash the screen. Meanwhile, the cam also drives the screen to vibrate, so that the stains remaining on the screen can be washed and shaken off. Moreover, the driving roller drives the sixth pulley to rotate through the fifth pulley and the third transmission belt, and then drives the second bevel gear to rotate through the fourth driving shaft and the first bevel gear. Furthermore, the blower and the driving block drive the air outlet to reciprocate above the screen, so that the air entering the feeding bin by the blower can be evenly blown onto the upper end of the screen through the air collecting flexible square pipe and the air outlet, so that some small water droplets that are not easily shaken off at the upper end of the screen can be completely blown off, fall onto the inner bottom wall of the reduction bin and then enter the sewage bin for storage, further improving the cleaning quality of the screen, and thus ensuring the subsequent reduction effect of the activated carbon particles.

Detailed implementation mode

[0021] The following combines the description drawings of the specification and the embodiments to make a more detailed description of the specific implementation mode of the present invention.

A mounting ring 2 is fixedly connected to the front end of the purification bin 1. A central part of the upper end of the purification bin 1 is fixedly connected to an air inlet 6. A first air chamber 7 is fixedly connected to the front end of the mounting ring 2. An air outlet 8 is fixedly connected to the upper end of the first air chamber 7. A first connecting pipe 9 is fixedly connected to the lower end of the first air chamber 7. An air outlet pipe 10 is fixedly connected to the lower end of the first connecting pipe 9. A first air wheel 11 is rotatably connected inside the first air chamber 7. A driving shaft 12 is fixedly connected to the middle of the first air wheel 11. A driving gear 13 is fixedly connected to the outer periphery of the rear end of the driving shaft 12. The driving gear 13 is meshed with a toothed ring 14. A runner 15 is fixedly connected to the middle of the toothed ring 14. A mounting seat 16 is rotatably connected inside the runner 15. A first pulley 20 is fixedly connected to the outer periphery of the rear end of the runner 15. The first pulley 20 is connected to a second pulley 22 through a first transmission belt 21.

[0023] Specifically, connect the air inlet 6 to the exhaust duct of the spray booth and connect the air outlet 8 to the discharge duct. Start the heating plate 28 in the heating chamber 27 to heat the cleaning liquid in the heating chamber 27 to boiling and increase the pressure. Particles such as paint mist, volatile organic compounds, and heavy metal ions first pass through the activated carbon filtration in the runner 15. Then, the clean gas enters the inside of the air outlet pipe 10 through the opening above the mounting seat 16, and then passes through the first connecting pipe 9, the first air chamber 7, and the air outlet 8 to enter the discharge duct for discharge. When the discharged clean gas passes through the first air chamber 7, it will blow the first air wheel 11 to rotate, and then drive the driving gear 13 to rotate through the driving shaft 12, and then drive the runner 15 to rotate through the toothed ring 14. Thus, it is realized that the air entering the inside of the purification bin 1 can always be filtered by new activated carbon particles, ensuring that the filtered air can meet the emission standards and avoiding the reduction of the efficiency of the activated carbon in filtering air after filtering air for a period of time, resulting in the discharged air not meeting the environmental protection emission standards.

[0024] In this embodiment, the activated carbon reduction section includes a reduction bin 18 and a third driving shaft 31.

[0025] In this embodiment, a first protective plate 3 is fixedly connected to the outer periphery of the rear end of the purification bin 1.

A second protective plate 4 is fixedly connected to the right part of the rear end of the reduction bin 18.

[0027] Specifically, the rotating runner 15 drives new activated carbon particles to filter air, eliminating the need for manual replacement of activated carbon particles, reducing labor costs, and avoiding the situation where ineffective filtration of particles such as volatile organic compounds and heavy metal ions in the air due to untimely manual replacement of activated carbon leads to serious air pollution in the discharged air. When the runner 15 rotates, it drives the second pulley 22 to rotate through the first pulley 20 and the first transmission belt 21, and then drives the discharge pipe 24 to rotate through the second drive shaft 23, intermittently and quantitatively sending the activated carbon particles after filtering air to the upper end of the screen 25. At the same time, the discharge pipe 24 drives the turbine 35 to rotate through the worm 37, causing the ventilation holes 36 on one side to rotate to the lower end of the fourth connecting pipe 38, thereby connecting the fourth connecting pipe 38 and the third connecting pipe 33. The high-temperature and high-pressure gas in the heating bin 27 enters the second air bin 29 through the second connecting pipe 17, and then enters the spray pipe network 39 through the third connecting pipe 33 and the fourth connecting pipe 38, spraying onto the activated carbon particles at the upper end of the screen 25 to restore the activated carbon.

[0028] In this embodiment, the steam control assembly includes an air flow control bin 34. A turbine 35 is rotatably connected to the inside of the air flow control bin 34.

[0030] In this embodiment, the activated carbon conveying part includes a feeding bin 46. A conveying belt 44 is rotatably connected inside the feeding bin 46. A driven roller 45 is arranged in the upper inner part of the conveying belt 44. A driving roller 43 is arranged in the lower inner part of the conveying belt 44. The front end of the driving roller 43 is fixedly connected with a fourth belt pulley 42. The fourth belt pulley 42 is connected with a third belt pulley 40 through a second transmission belt 41. The middle part of the third belt pulley 40 is fixedly connected to the outer periphery of the front end of the third driving shaft 31.

[0031] In this embodiment, the front and rear ends of the driving roller 43 are rotatably connected to the front and rear parts of the lower end of the feeding bin 46, and the front and rear ends of the driven roller 45 are rotatably connected to the front and rear parts of the upper end of the feeding bin 46.

[0032] Specifically, when the gas passes through the second air chamber 29, the second wind wheel 30 drives the third driving shaft 31 to rotate, and then through the cooperation of the cam 32 and the spring rod 26, the screen 25 is driven to rotate up and down, so that the activated carbon can be evenly spread on the upper end of the screen 25 and conveyed to the right, so that the used activated carbon can be completely reduced. Moreover, the third driving shaft 31 synchronously drives the fourth belt pulley 42 to rotate through the third belt pulley 40 and the second transmission belt 41, and then drives the conveying belt 44 to rotate through the cooperation with the driven roller 45, so that the reduced activated carbon can be conveyed back to the purification chamber 1 again.

[0033] In this embodiment, the activated carbon drying part includes an I-shaped support 62. A reciprocating lead screw 59 is rotatably connected to the middle part of the I-shaped support 62. A driving block 60 is threadedly connected to the outer periphery of the reciprocating lead screw 59. The front and rear sides of the upper end of the driving block 60 are fixedly connected with air collecting flexible square pipes 51. The upper ends of the air collecting flexible square pipes 51 are fixedly connected to the middle opening of the front end of the feeding bin 46. A fan 50 is fixedly connected to the middle opening of the right end of the feeding bin 46. The left end of the reciprocating lead screw 59 is fixedly connected with a second bevel gear 58.

A heating pipe 48 is fixedly connected to the upper middle part of the feeding bin 46. The lower end of the heating pipe 48 is fixedly connected with a sixth connecting pipe 49.

[0034] In this embodiment, the outer periphery of the driving block 60 is slidably connected to the middle of the I-shaped bracket 62. The lower end of the fan 50 is fixedly connected to the upper right side of the reduction bin 18. The lower end of the sixth connecting pipe 49 is communicated with the upper end of the spray pipe network 39. The upper end of the heating pipe 48 is communicated with the upper end of the fifth connecting pipe 47.

[0035] Specifically, when the discharge pipe 24 rotates to the vertical state, that is, when the discharge pipe 24 blocks the upper opening of the heating bin 27, the activated carbon particles no longer fall at this time. At the same time, the worm 37 drives the turbine 35 to rotate, so that the gas inside the fourth connecting pipe 38 no longer enters. Instead, another vent hole 36 rotates to the lower end of the fifth connecting pipe 47, allowing the high-temperature and high-pressure gas to enter the sixth connecting pipe 49. At the same time, the fan 50 is started to blow hot air towards the activated carbon particles between the conveyor belt 44 and the feeding bin 46, drying the activated carbon particles before they enter the purification bin 1. Thus, the used activated carbon particles can be reduced, dried, and re-transported back into the runner 15 inside the purification bin 1, further reducing the possibility that the discharged air fails to meet the standards due to untimely manual replacement and reducing the cost of using activated carbon particles. The cooled hot steam re-enters the spray pipe network 39 through the sixth connecting pipe 49 to wash the screen 25. At the same time, the cam 32 also drives the screen 25 to vibrate, so that the stains remaining on the screen 25 can be washed and shaken off. Moreover, the driving roller 43 drives the pulley six 55 to rotate through the pulley five 53 and the third transmission belt 54, and then drives the bevel gear two 58 to rotate through the driving shaft four 56 and the bevel gear one 57. Then, through the fan 50 and the driving block 60, the air outlet 61 reciprocates above the screen 25, enabling the air from the fan 50 entering the feeding bin 46 to be evenly blown towards the upper end of the screen 25 through the air collecting flexible square pipe 51 and the air outlet 61, so that some small water droplets that are not easily shaken off at the upper end of the screen 25 can be completely blown off, falling onto the inner bottom wall of the reduction bin 18 and then entering the sewage bin 19 for storage, further improving the cleaning quality of the screen 25 and thus ensuring the subsequent reduction effect of the activated carbon particles.

[0036] Working principle: First, connect the air inlet 6 to the exhaust duct of the spray booth and the air outlet 8 to the discharge duct. Start the heating plate 28 in the heating chamber 27 to heat the cleaning liquid in the heating chamber 27 to boiling and increase the pressure. Particles such as paint mist, volatile organic compounds, and heavy metal ions first pass through the activated carbon filter in the rotating wheel 15. Then, the clean gas enters the interior of the outlet pipe 10 through the opening above the mounting seat 16, and then enters the discharge duct through the first connecting pipe 9, the first air chamber 7, and the air outlet 8 for discharge. When the discharged clean gas passes through the first air chamber 7, it will blow the first air wheel 11 to rotate, and then drive the driving gear 13 to rotate through the first driving shaft 12, and then drive the rotating wheel 15 to rotate through the toothed ring 14. Thus, the air entering the purification chamber 1 can always be filtered by new activated carbon particles, ensuring that the filtered air can meet the emission standards, avoiding the reduction of the efficiency of activated carbon filtering air after filtering air for a period of time, resulting in the discharged air not meeting the environmental protection emission standards. At the same time, the rotating rotating wheel 15 drives new activated carbon particles to filter air, eliminating the need for manual replacement of activated carbon particles, reducing labor costs, and avoiding the situation where the activated carbon cannot effectively filter particles such as volatile organic compounds and heavy metal ions in the air due to untimely manual replacement, causing serious air pollution. When the rotating wheel 15 rotates, it drives the second pulley 22 to rotate through the first pulley 20 and the first transmission belt 21, and then drives the discharge pipe 24 to rotate through the second driving shaft 23, thereby intermittently and quantitatively sending the activated carbon particles after filtering air to the upper end of the screen 25. At the same time, the discharge pipe 24 drives the turbine 35 to rotate through the worm 37, so that one ventilation hole 36 rotates to the lower end of the fourth connecting pipe 38, thus connecting the fourth connecting pipe 38 and the third connecting pipe 33. The high-temperature and high-pressure gas in the heating chamber 27 enters the second air chamber 29 through the second connecting pipe 17, and then enters the spray pipe network 39 through the third connecting pipe 33 and the fourth connecting pipe 38, and sprays onto the activated carbon particles at the upper end of the screen 25 to restore the activated carbon. At the same time, when the gas passes through the second air chamber 29, it drives the third driving shaft 31 to rotate through the second air wheel 30, and then drives the screen 25 to rotate up and down through the cooperation of the cam 32 and the spring rod 26, so that the activated carbon can be evenly spread on the upper end of the screen 25 and conveyed to the right, enabling the used activated carbon to be completely restored. Moreover, the third driving shaft 31 synchronously drives the fourth pulley 42 to rotate through the third pulley 40 and the second transmission belt 41, and then drives the conveyor belt 44 to rotate through the cooperation with the driven roller 45, so that the restored activated carbon can be conveyed back to the purification chamber 1 again. When the discharge pipe 24 rotates to the vertical state, that is, when the discharge pipe 24 blocks the upper opening of the heating chamber 27, the activated carbon particles no longer fall. At the same time, the worm 37 drives the turbine 35 to rotate, so that the gas inside the fourth connecting pipe 38 no longer enters, and the other ventilation hole 36 rotates to the lower end of the fifth connecting pipe 47, allowing the high-temperature and high-pressure gas to enter the sixth connecting pipe 49. At the same time, start the fan 50,Hot air is blown onto the activated carbon particles between the conveyor belt 44 and the feed bin 46, so that the activated carbon particles are dried before entering the purification chamber 1. Thus, the used activated carbon particles can be reduced and dried, and then re-transported back into the runner 15 inside the purification chamber 1, further reducing the possibility that the discharged air fails to meet the standards due to untimely manual replacement, and reducing the cost of using activated carbon particles. The cooled hot steam enters the spray pipe network 39 again through the sixth connecting pipe 49 to wash the screen 25. At the same time, the cam 32 also drives the screen 25 to vibrate, so that the stains remaining on the screen 25 can be washed and shaken off. Moreover, the driving roller 43 drives the pulley six 55 to rotate through the pulley five 53 and the third transmission belt 54, and then drives the bevel gear two 58 to rotate through the driving shaft four 56 and the bevel gear one 57. Then, the blower 50 and the driving block 60 drive the air outlet 61 to reciprocate above the screen 25, so that the air entering the feed bin 46 by the blower 50 can be evenly blown onto the upper end of the screen 25 through the air collecting flexible square pipe 51 and the air outlet 61, so that some small water droplets that are not easily shaken off at the upper end of the screen 25 can be completely blown off, fall onto the inner bottom wall of the reduction chamber 18 and then enter the sewage bin 19 for storage, further improving the cleaning quality of the screen 25, and thus ensuring the subsequent reduction effect on the activated carbon particles.
