Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste gas treatment, in particular to a color-coated plate waste gas treatment device and method. BACKGROUND

[0002] Color-coated plate is a plate material obtained by coating one or more layers of liquid paint on a cold-rolled steel strip or galvanized steel strip as a base plate through roll coating, and then baking and cooling. After color coating, the color-coated plate has the advantages of light weight, beauty, and good corrosion resistance, and is widely used in the construction industry, shipbuilding industry, vehicle manufacturing industry, furniture industry, and electrical industry.

[0003] The main production processes of color-coated plate are: uncoiling, pretreatment, coating, baking, post-treatment, and winding. In the coating and baking processes, due to the dispersion of paint mist, the color-coated waste gas contains a large amount of particulate impurities and solvents mainly in the form of paint mist. Direct emission of paint mist can cause air pollution and damage to the respiratory system of the human body. Therefore, in the production process of color-coated plate, a waste gas treatment device is needed to treat the color-coated waste gas. Due to the large amount of paint mist in the color-coated waste gas, a spray tower is often used to realize the atomization and adsorption treatment of paint mist in the color-coated waste gas by using internal filtering fillers such as plastic balls, Raschig rings, Pall rings, and stepped rings.

[0004] As disclosed in Chinese patent CN113209750A, a paint spraying waste gas purification system is disclosed. This paint spraying waste gas purification system uses a water curtain spray table to purify the inhaled waste gas, then uses a pre-filter to pre-filter the waste gas, uses a spray tower to spray and filter the waste gas, and uses a photo-oxygen purifier to photo-oxygen purify the waste gas, and finally uses an activated carbon adsorption box to adsorb and filter the waste gas.

[0005] However, during the filtering and intercepting process of paint mist in the spray coating waste gas, a large amount of paint mist impurities and residual water mist entraining impurities often remain in the fillers after each filtering process. Long-term retention and adhesion result in a significant reduction in the filtering and intercepting characteristics of the filtering fillers, greatly slowing down the effectiveness of the spray filtering process of paint mist in the waste gas.

The lifting plates 14 are pushed in cycles by the transmission belt 13 to cycle the filtered filler 8 after vibration and removal of impurities to the lifting plates 14 at the bottom, and the filtered filler 8 after vibration and removal of impurities at the bottom is lifted and turned to the other side at the top by the transmission of the lifting plates 14, so that the filtered filler 8 at the bottom of the slope 74 is continuously fed, and the filtered filler 8 is cycled up and down.

[0055] In addition, the upper middle part of the filler hole plate 71 is provided with a driving assembly for driving the rotating shell 11 and the transmission belt 13 to rotate, so that the paddle 12 on the rotating shell 11 rotates and reciprocates to stretch and shrink, and the filtered filler 8 at the bottom of the slope 74 is vibrated and pushed to the lifting plates 14 of the transmission belt 13, and the lifting plates 14 driven by the transmission belt 13 turn the filtered filler 8 at the bottom to the other side at the top. By driving of the driving assembly, the paddle 12 and the lifting plate 14 are integrally linked to vibrate and remove impurities from the filtered filler 8, and at the same time, the filtered filler 8 is turned up and down, so that the filtered filler 8 is removed and kept in a uniform mixing state to keep the impurities in the color-coated waste gas being efficiently filtered and retained.

[0056] Please refer to Figures 4-6 、 Figures 8-18 To realize the pushing and vibration of the filtered filler 8, the driving assembly includes a machine shell 10 arranged above the middle part of the filler hole plate 71, and a first driving shaft 16 arranged inside the machine shell 10. The bottom end of the first driving shaft 16 is sequentially provided with a bevel gear one 20 and a bevel gear two 21 from outside to inside. A third driving shaft 26 is arranged at the bottom end of the machine shell 10, one end of the third driving shaft 26 is connected with the rotating shell 11, and the other end of the third driving shaft 26 is provided with a bevel gear one 22 engaged with the bevel gear one 20. By driving of a driving motor 15 arranged on the machine shell 10, the first driving shaft 16 is driven to rotate, and then the bevel gear one 20 is driven to rotate. By engagement transmission of the bevel gear one 20 and the bevel gear two 21, the third driving shaft 26 is driven to rotate, and the rotating shell 11 and the paddle 12 are driven to rotate in linkage, so that the filtered filler 8 at the bottom of the slope 74 is continuously pushed and sent to the side near the transmission belt 13.

[0057] As a further aspect of the present embodiment, the driving assembly further comprises a fourth driving shaft 27 extending through the third driving shaft 26 into the interior of the rotating shell 11, the fourth driving shaft 27 being provided with a driving end along its axial direction for intermittently rotating the rotating seat 33, and the fourth driving shaft 27 being provided with a bevel gear 23 engaged with the second bevel gear plate 21, wherein the driving end comprises a transmission gear plate 36 provided on one side of the rotating seat 33, a second support 29 provided inside the rotating shell 11 away from the first support 28, the second support 29 being provided with at least one set of transmission gears 38 engaged with the transmission gear plate 36, and a sector gear 39 provided on the axial direction of the fourth driving shaft 27, the sector gear 39 being intermittently engaged with the transmission gears 38. When the driving motor 15 drives the first driving shaft 16 to rotate, the second bevel gear plate 21 is synchronously rotated, the fourth driving shaft 27 is driven to rotate by the engagement transmission between the second bevel gear plate 21 and the bevel gear 23, and then the sector gear 39 is driven to rotate. At this time, the engagement combination between the transmission gears 38 and the transmission gear plate 36 is synchronously rotated with the paddle 12, but when the sector gear 39 is rotated to be engaged with the transmission gears 38, the engagement transmission between the sector gear 39 and the transmission gears 38 is maintained, the transmission gear plate 36 is intermittently rotated, and the intermittent thrust is generated to intermittently rotate the rotating seat 33.

[0058] Further, Figures 10-18 , the rotating shell 11 is provided with the first support 28, the middle part of the first support 28 is provided with the rotating shaft 34, the first support 28 and the rotating shaft 34 have the clockwork 35 therebetween, one end of the rotating shaft 34 is provided with the rotating seat 33, the rotating seat 33 is provided with at least one set of arm force push rods 32 along its circumferential direction, the arm force push rods 32 are connected with the paddle 12 and drive the paddle 12 to stretch and contract, the rotating seat 33 is intermittently rotated, on one hand, the rotating seat 33 drives the arm force push rods 32 to synchronously rotate, and the rotating thrust of the arm force push rods 32 pushes the paddle 12 out of the rotating shell 11, on the other hand, the rotating seat 33 drives the clockwork 35 on the rotating shaft 34 to tighten, and then, after the intermittent rotation thrust of the rotating seat 33 disappears, the clockwork 35 is reset to generate the reset thrust, the rotating seat 33 is rotated to reset, the paddle 12 is driven to inductively retract into the rotating shell 11, and then the reciprocating stretching and contraction of the paddle 12 generates the stretching and contraction thrust, the stretching and contraction thrust vibrates the filter filler 8 between the paddles 12 to vibrate and separate the impurities inside the filter filler 8.

[0059] In addition, the gear transmission ratio of the bevel gear one 22 and the bevel gear two 23 is greater than the gear transmission ratio of the bevel gear two 23 and the bevel gear one 22. According to the principle that the greater the gear transmission ratio, the slower the rotation speed, the gear transmission ratio of the bevel gear one 22 and the bevel gear two 23 is greater, so the rotation speed of the third drive shaft 26 driving the rotating shell 11 is slower, the rotation speed of the internal transmission gear 38 and the transmission gear plate 36 is slower, and the gear transmission ratio of the bevel gear two 23 and the bevel gear one 22 is smaller, so the rotation speed of the fourth drive shaft 27 relative to the rotating shell 11 is faster, and the shaft rod of the fourth drive shaft 27 can overcome the rotation speed of the transmission gear 38 and the transmission gear plate 36 and intermittently mesh with them to generate an active intermittent driving force.

[0060] It should be noted that by providing the sealing gasket strip 31 on the rotating shell 11 to seal and guide the extension and contraction of the paddle 12, the air and water mist outside can be isolated when the paddle 12 extends and contracts, so as to reduce the entry of water mist and air into the rotating shell 11, and by providing the anti-extrusion boss 30 at the tail end of the paddle 12, the paddle 12 can be prevented from sliding out of the rotating shell 11 when it extends and contracts.

[0062] It should be noted that a channel is reserved between the partition baffle 73 and the transmission belt 13 to provide the turnover of the lifting plate 14, so that the lifting plate 14 can be circulated and transported along the partition baffle 73, and when the lifting plate 14 is turned to the side close to the paddle 12, the plate surface of the lifting plate 14 is arranged to be inclined upward. By the arrangement of the partition baffle 73 and the transmission belt 13, the filter filler 8 is divided into multiple parts, and under the transmission and driving of the transmission belt 13 to the lifting plate 14, the filter filler 8 can be moved up and down to the adjacent part in turn, and by arranging the lifting plate 14 to be inclined upward when it is close to the paddle 12 side, the lifting plate 14 is turned to the side of the paddle 12, which has the ability to collect and lift the filter filler 8. At this time, since the lifting plate 14 turned to the bottom has accumulated filter filler 8 when it is gradually transported upward, it will not collect filter filler 8 in the middle or upper part in the continuous upward channel, so as to maintain the continuous upward turning of the bottom filter filler 8, and mix the filter filler 8 up and down.

[0063] In addition, please refer to Figures 1-2 In order to realize the periodic unloading, cleaning or replacement of the filter filler 8, the maintenance end cover 6 is arranged on the spray tower 1, the maintenance end cover 6 is arranged on the spray tower and is staggered with the rotating shell 11 and the transmission belt 13, and the maintenance end cover 6 is arranged in the same plane with the filler hole plate 71. When it is necessary to replace or clean the filter filler 8 in the later period, only the maintenance end cover 6 needs to be opened. At this time, the filter filler 8 is transported to the area close to the maintenance end cover 6 in turn by the combination of the transmission belt 13 and the lifting plate 14, and when the filter filler 8 is turned to the area close to the maintenance end cover 6, the filter filler 8 is discharged from the maintenance end cover 6 for cleaning or replacement, which does not need to disassemble the spray tower 1, and is more convenient and efficient for daily replacement and cleaning of the filter filler 8.

[0064] In addition to the above, it also includes the air inlet 2 arranged at the bottom of the spray tower 1, the exhaust port 3 arranged at the top of the spray tower 1, the blowdown port 5 arranged at the bottom of the spray tower 1, and the spray ring pipe 92 arranged above the filter filler 8. The spray ring pipe 92 is arranged on the spray tower 1 through the support frame 91, and is provided with at least one set of atomizing nozzles 93 along the circumference. The spray ring pipe 92 is connected with the external water supply device through the water supply pipe 4. When the color-coated waste gas is treated by spraying, the color-coated waste gas is transported into the spray tower 1 through the air inlet 2, so that the color-coated waste gas is transported and circulated in a downward flow manner. In the flow process, the paint mist and impurities in the color-coated waste gas are filtered and intercepted by the filter filler 8. The clean water is transported into the spray assembly composed of the support frame 91, the spray ring pipe 92 and the atomizing nozzle 93 through the water supply pipe 4 by the pumping of the external water supply device. The clean water is atomized and sprayed out through the atomizing nozzle 93 to form a uniform water mist surface. The impurities in the waste gas are adsorbed and settled, and the water mist is dispersed into the filter filler 8 to further enhance the combination and adsorption efficiency of the impurities in the color-coated waste gas. Then, the waste gas treated by spraying is discharged through the exhaust port 3 for further treatment, and the sewage produced by spraying is finally discharged through the blowdown port 5.
