DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] Depend on Figure 1-10The present invention relates to a workpiece spraying waste gas collection and treatment device, comprising an air suction hood 1, a first fan 2, a filter 3, an adsorption box 4, an exhaust pipe 5, a second fan 6 and a catalytic combustion device 7, the air suction hood 1 is connected to the first fan 2, the first fan 2 is connected to the filter 3, the filter 3 is connected to the adsorption box 4, the adsorption box 4 is connected to the exhaust pipe 5, one end of the second fan 6 is connected to the adsorption box 4, the other end of the second fan 6 is connected to the catalytic combustion device 7, the four corners of the interior of the adsorption box 4 are fixedly provided with vertical baffles 8, and the interior of the adsorption box 4 is also fixedly provided with a plurality of horizontal baffles 9 , wherein an activated carbon adsorption mechanism is arranged on the inner side of four vertical baffles 8, and horizontal baffles 9 are distributed inside the activated carbon adsorption mechanism, the activated carbon adsorption mechanism comprises a driving member, a plurality of belt rollers 10 and a conveyor belt 11, the plurality of belt rollers 10 are connected by the conveyor belt 11, wherein the driving member is used to drive one of the belt rollers 10 to rotate, mounting grooves 12 are evenly provided on the conveyor belt 11, an activated carbon adsorption member is fixedly arranged inside the mounting grooves 12, a curved portion 13 for adsorbing and filtering the exhaust gas and a horizontal portion 14 for recycling the activated carbon adsorption member are formed on the conveyor belt 11;

[0032] With such a design, when in use, the exhaust gas generated by the workpiece spraying is sucked in through the suction hood 1, and then transported to the inside of the filter 3 for filtration through the first fan 2, and the paint mist and dust in the exhaust gas are filtered through the filter 3, and the treated exhaust gas enters the inside of the adsorption box 4, and the adsorbable gas in the exhaust gas is adsorbed and treated by the activated carbon adsorption mechanism, and then discharged through the exhaust pipe 5, wherein a UV lamp can be fixedly arranged at the axis of the exhaust pipe 5, and part of the gas in the exhaust gas can be photocatalytically treated. When the adsorption effect of the activated carbon adsorption mechanism decreases, the activated carbon adsorption mechanism can be heated by heating, so that the gas adsorbed in the activated carbon adsorption mechanism is released after being heated, and then the released gas is transported to the inside of the catalytic combustion device 7 for treatment through the second fan 6, thereby realizing the treatment process of the workpiece spraying exhaust gas;

[0033] Taking into account that during use, the activated carbon adsorbent located on the front side of the adsorption box 4 contacts the exhaust gas more fully, and then the exhaust gas passes through the activated carbon adsorbent located on the front side of the adsorption box 4 and contacts the activated carbon adsorbent on the rear side of the adsorption box 4 again. Since the exhaust gas has been adsorbed and treated by the activated carbon adsorbent located on the front side of the adsorption box 4, the activated carbon adsorbent located on the front side of the adsorption box 4 is more easily saturated. This will cause the activated carbon adsorbent located on the front side of the adsorption box 4 to lose its function and need to be replaced or treated, while the activated carbon adsorbent located on the rear side of the adsorption box 4 can still be adsorbed. If they are replaced at the same time, the activated carbon adsorbent mechanism will undoubtedly be insufficiently utilized. Therefore, after a period of time, the belt roller 10 can be driven to rotate by the driving member, and the conveyor belt 11 can be driven to move by the belt roller 10, so that the activated carbon adsorbent located on the rear side of the adsorption box 4 is transferred to the front side of the adsorption box 4, thereby realizing full utilization of the activated carbon adsorption mechanism.

[0034] Specifically, the driving component includes a driving motor 15, a small gear 16 and a large gear 17, wherein the driving motor 15 is fixedly arranged on the adsorption box 4, the small gear 16 is fixedly arranged on the output shaft of the driving motor 15, the large gear 17 is fixedly arranged on the corresponding belt roller 10, and the small gear 16 is meshed with the large gear 17; with such a design, when in use, the driving motor 15 drives the small gear 16 to rotate, the small gear 16 drives the large gear 17 to rotate by meshing, and the large gear 17 drives the corresponding belt roller 10 to rotate, thereby realizing the driving process of the belt roller 10.

[0035] Specifically, the activated carbon adsorbent includes an activated carbon powder layer 18, two filter cotton layers 19 and two filter mesh layers 20, wherein the activated carbon powder layer 18 is arranged in the middle of the installation groove 12, the two filter cotton layers 19 are respectively on both sides of the activated carbon powder layer 18, the two filter mesh layers 20 are distributed on both sides of the two filter cotton layers 19, and the two filter mesh layers 20 are fixed to the installation groove 12; with this design, since the activated carbon powder layer 18, the filter cotton layer 19 and the filter mesh layer 20 can all move with the movement of the conveyor belt 11, when passing the corner of the conveyor belt 11, the activated carbon powder layer 18 can be loosened to avoid the activated carbon powder layer 18 from agglomerating after being placed for a long time, thereby ensuring the use effect of the activated carbon powder layer 18.

[0036] Furthermore, two recycling mechanisms are fixedly arranged inside the adsorption box 4, and the two recycling mechanisms are distributed on both sides of the horizontal portion 14, one of which is fixedly arranged on the corresponding horizontal baffle 9, and the other is fixedly arranged on the inner wall of the adsorption box 4 and connected to the second fan 6;

[0037] The recycling mechanism includes an open shell 21, and two heaters 22 and four telescopic parts are fixedly arranged inside the open shell 21, wherein the four telescopic parts are fixedly arranged on the corresponding horizontal baffles 9, and the two heaters 22 are symmetrically fixedly arranged with heat-conducting rings 23, and the heat-conducting rings 23 at both ends of each heater 22 are respectively sleeved on the outside of the corresponding telescopic parts; the telescopic parts include a cylinder 24, a piston rod 25 and a telescopic spring 26, wherein the cylinder 24 is fixedly arranged on the inner side of the open shell 21, the piston rod 25 is slidably arranged inside the cylinder 24, and the telescopic spring 26 surrounds the outer side of the piston rod 25 and is located between the piston rod 25 and the cylinder 24;

[0038] With this design, when in use, when the activated carbon adsorbent that has been used for a long time is driven by the conveyor belt 11 to enter between the two recycling mechanisms, the interior of the open shell 21 can be heated by the heater 22, and the heat generated by the heater 22 is transferred to the interior of the cylinder 24 through the heat-conducting ring 23, and the air in the cylinder 24 is heated, so that the air pressure in the cylinder 24 becomes higher. Under the action of the air pressure, the cylinder 24 moves in the direction close to the conveyor belt 11, and the cylinder 24 squeezes the telescopic spring 26, so that the open shell 21 fits closely to the conveyor belt 11. Since two recycling mechanisms are arranged on the conveyor belt 11, the activated carbon adsorbent on the conveyor belt 11 can be closed from both sides through two open shells 21, and then the activated carbon adsorbent located between the two open shells 21 can be heated by the heater 22 to release the gas from the activated carbon adsorbent, and then the released gas can be transported to the inside of the catalytic combustion device 7 for treatment through the second fan 6 to realize the recycling of the activated carbon adsorbent, wherein a one-way air valve is fixedly embedded on the open shell 21 to ensure the flowability of the gas;

[0039] After the activated carbon adsorbent is heated, the heater 22 is stopped and the air pressure in the cylinder 24 is reduced with natural cooling. Under the action of the air pressure, the cylinder 24 moves away from the conveyor belt 11, thereby preventing the open shell 21 from affecting the use of the conveyor belt 11.

[0040] Furthermore, a receiving groove 27 is formed at the open end of the open shell 21, a sealing strip 28 is fixedly disposed inside the receiving groove 27, a cavity 29 is formed inside the sealing strip 28, and the cavity 29 is connected to the inside of the corresponding cylinder 24 through a conduit;

[0041] With such a design, when the open shell 21 contacts the conveyor belt 11, the air pressure in the cylinder 24 will also be transmitted to the cavity 29 in the sealing strip 28, causing the sealing strip 28 to expand. The expanded sealing strip 28 improves the sealing performance between the open shell 21 and the conveyor belt 11; and when the air pressure in the cylinder 24 decreases, the sealing strip 28 will also retract, so that the sealing strip 28 can be stored in the interior of the accommodating groove 27, which is more convenient.

[0042] Considering that after long-term use, some dust will accumulate on the surface of the conveyor belt 11 and needs to be processed, two closed chambers 30 are formed between the corresponding vertical baffles 8, the corresponding horizontal baffles 9, the conveyor belt 11 and the adsorption box 4, and dust cleaning mechanisms are provided inside the two closed chambers 30. The top of the adsorption box 4 is provided with a dust suction pipe 31, a dust suction fan 32 and a filter box 33, wherein the two ends of the dust suction pipe 31 are respectively connected to the two closed chambers 30, the middle part of the dust suction pipe 31 is connected to the dust suction fan 32 through a conduit, the dust suction fan 32 is connected to the filter box 33, and the dust suction fan 32 and the filter box 33 are both fixedly arranged on the adsorption box 4;

[0043] The dust cleaning mechanism includes a dust cleaning brush rod 34, a first gear 35 and a second gear 36, wherein the dust cleaning brush rod 34 is rotatably arranged in the closed cavity 30, the first gear 35 is fixedly arranged on the dust cleaning brush rod 34, and the second gear 36 is fixedly arranged on the belt roller 10 corresponding thereto, the first gear 35 is meshed with the second gear 36, and the diameter value of the first gear 35 is smaller than the diameter value of the second gear 36;

[0044] With such a design, during the movement of the conveyor belt 11, the second gear 36 on the belt roller 10 drives the first gear 35 to rotate by meshing, and the first gear 35 drives the corresponding cleaning brush rod 34 to rotate. The dust on the surface of the conveyor belt 11 is cleaned by the cleaning brush rod 34, and the cleaned dust remains inside the closed cavity 30. The dust in the closed cavity 30 is extracted by the dust suction fan 32, and then transported to the inside of the filter box 33 for filtration and discharge.

[0045] It should be noted that the filter 3 and the filter box 33 mentioned above are both provided with filter screens and filter elements inside, which are all conventional settings and thus will not be described in detail.

[0046] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
