Technical Field

[0001] The invention relates to the technical field of powder coating waste gas recovery, and in particular to an automobile parts spraying dust recovery system. Background Art

[0002] In the process of auto parts production, auto parts need to be sprayed, and auto parts spraying refers to the process of surface treatment of auto parts to improve their appearance quality and corrosion resistance. In the spraying process, if powder coating is used, powder particles will be generated during the spraying and curing process. Even if liquid coating is used, impurities may be generated during the spraying of the coating due to poor atomization or improper operation of the spray gun.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) When the dust falls from the bottom opening of the first fan into the separation screen drum, the particulate impurities contained in the dust continue to sink under the action of gravity, thereby achieving the purpose of preliminary separation of the particulate impurities and the dust-like suspended impurities in the dust. As the separation screen drum continues to rotate, the dust-like suspended impurities separated from the separation screen drum can be adsorbed in an orderly manner by the dust collection component. At the same time, the mesh of the separation screen drum facing the dust collection component always remains unobstructed, which is conducive to ensuring the adsorption effect of the dust-like suspended impurities inside the separation screen drum. During the rotation, the rubber roller will intermittently roll on the surface of the convex block, and by utilizing the height difference between the convex block and the inner wall of the bottom of the separation protection box, the rubber roller can carry the separation screen drum to rise and then fall as a whole, and repeat the cycle, thereby causing the separation screen drum to vibrate, which is conducive to shaking off the particulate impurities adhering to the inner wall of the separation screen drum, avoiding the particulate impurities from clogging the mesh, and improving the adsorption effect of dust-like suspended impurities. In addition, the separation link of the particulate impurities adopts a non-energy-based method to provide power, which effectively reduces the energy consumption of the device during dust recovery.

[0023] (2) The circulating water pump is used to extract water from the circulating pool and spray it out through the spray pipe head, so that the separated particulate impurities and some impurities containing powdery floating matter are wetted after contact with water, and the larger particulate impurities after being wetted can smoothly fall into the circulating pool, and the remaining impurities containing a small amount of powdery floating matter can enter the dust bag through the square groove and the through hole, so as to achieve the purpose of secondary removal of particulate impurities in the dust-like suspended impurities. Compared with the traditional method of directly using dust bags to collect impurities, the particulate impurities in the impurities are first separated and then wetted, which speeds up the separation of particulate impurities, thereby ensuring the impurity filtering effect. The isolation cover can be used to separate the water containing particulate impurities in the circulating pool from the water intake of the circulating water pump, thereby preventing the circulating water pump from inhaling particulate impurities, which helps to ensure the stability of the use of the circulating water pump and increase its service life. In addition, the circulating water pump is used to circulate the water inside the circulating pool and then spray it out through the spray pipe head, which can save water.

At the same time, the mesh of the separation sieve drum 402 facing the dust collecting component 601 is always kept unobstructed, which is conducive to ensuring the absorption effect of the dust-like suspended impurities inside the separation sieve drum 402. When the separation sieve drum 402 rotates, the rubber roller 403 will be intermittent. Rolling on the surface of the protrusion 502, using the height difference between the protrusion 502 and the bottom inner wall of the separation protection box 401, the rubber roller 403 can bring the separation screen drum 402 up and down as a whole, and repeat this cycle, thereby causing the separation screen drum 402 to vibrate, which is conducive to shaking off the particulate impurities adhered to the inner wall of the separation screen drum 402, avoiding the particulate impurities from clogging the mesh, and improving the adsorption effect of dust-like suspended impurities. In addition, the power is provided in a non-energy way, which effectively reduces the energy consumption of the device during the dust recovery period.

[0041] Among them, the separated particulate impurities and some dust-like suspended impurities are wetted after contacting with water, and the wetted particulate impurities can smoothly fall into the inside of the circulation pool 801, and the remaining dust-like suspended impurities can enter the dust bag 602 through the square groove 605 and the through hole 604, so as to achieve the purpose of secondary removal of particulate impurities in the dust-like suspended impurities. The isolation cover 705 can be used to separate the water containing particulate impurities in the circulation pool 801 from the water suction port of the circulation water pump 704, so as to avoid the circulation water pump 704 from sucking in particulate impurities, which helps to ensure the stability of the circulation water pump 704 and improve its service life. In addition, the circulation water pump 704 is used to circulate and extract the water in the circulation pool 801, and then spray it out through the spray pipe head 703, which can save water. The particulate impurities collected in the circulation pool 801 flow into the sedimentation tank 802 under the effect of the height difference between the circulation pool 801 and the sedimentation tank 802;

[0042] Preferably, the outer wall of the bottom end of the collecting cover 302 is symmetrically fixedly connected with a support rod 901, the ends of the two support rods 901 are rotatably connected with the adjustment cover 902, the top side walls of the two adjustment covers 902 are hinged with a damping handle 903, and the two damping handles 903 are rotatably matched with the support rod 901;

[0043] Among them, by controlling the flipping angles of the two adjustment covers 902 through the two damping turning handles 903, the purpose of adjusting the opening size of the space enclosed by the bottom of the two adjustment covers 902 can be achieved, so that the device can meet the dust protection work of automobile parts of different sizes during spraying and avoid dust spillage;

[0044] The dust recovery system includes an air intake module, a filter module, a dust collection module, a dust recovery module and an exhaust module, wherein the air intake module, the filter module, the dust collection module, the dust recovery module and the exhaust module are connected by pipelines;

[0048] The dust recovery module is used to collect and store dust separated from the airflow;

[0049] The exhaust module is used to discharge the processed air to the outside.

[0050] The following are the complete usage steps and working principles of the above embodiment:

[0051] When the device is used, the automobile parts to be sprayed will be placed on the surface of the parts conveying platform 2, and the automobile parts will be conveyed by the parts conveying platform 2, so that the automobile parts can pass through the spraying pipe head 301 and the bottom of the collecting cover 302 in turn, and stay for a period of time, and then the automobile parts can be sprayed by the spraying component 3 in cooperation with the spraying pipe head 301. Since a large amount of impurities will be generated during the spraying process, and the impurities contain a large number of particulate impurities, the first fan 303 is started, so that the first fan 303 starts to operate, and the suction force generated will suck the impurities into the collecting cover 302. Since the inside of the collecting cover 302 is connected with the inside of the collecting pipe 304, the impurities sucked into the collecting cover 302 will be input into the first fan 303 through the collecting pipe 304, and then discharged into the inside of the recovery box 1 from the bottom opening of the first fan 303, completing the purpose of preliminary collection of impurities. Here, the impurities mainly include solid particulate impurities and solvent vapor deposits, so as to avoid the problem of impurities generated by the spraying pipe head 301 during the spraying of automobile parts and floating around to cause environmental pollution;

[0052] When impurities fall into the recovery box 1, they will first enter the separation screen drum 402. Since the bottom opening of the first fan 303 will blow out the impurities toward one side of the separation screen drum 402, under the action of wind, the rotating blades 405 can be blown to rotate with the separation screen drum 402 as a whole, so that the rubber roller 403 fixedly connected to the outer wall of the bottom end of the separation screen drum 402 can follow the rotation direction of the rotating blades 405 and roll on the bottom inner wall of the separation protection box 401, thereby ensuring that the separation screen drum 402 can rotate smoothly. In addition, the limiting ring 501 can be used to limit the rolling of the rubber roller 403, thereby ensuring the stability of the separation screen drum 402 during use. Since the impurities fall into the separation screen drum 402 from the bottom opening of the first fan 303, there is a height difference. During this period, the impurities will be in a short suspended state. At the same time, the particulate impurities contained in the impurities continue to sink under the action of gravity, so as to achieve the purpose of preliminarily separating the particulate impurities and dust-like suspended impurities in the impurities. Then the dust collection component 601 is started. The dust collecting component 601 absorbs the separated dust-like suspended impurities. As the separation sieve drum 402 continues to rotate, the separated dust-like suspended impurities inside the separation sieve drum 402 can be orderly adsorbed by the dust collecting component 601. At the same time, the mesh of the separation sieve drum 402 facing the dust collecting component 601 is always kept unobstructed, which is conducive to ensuring the adsorption effect of the dust-like suspended impurities inside the separation sieve drum 402. When the separation sieve drum 402 rotates, the rubber roller 403 will intermittently roll on the protrusion 50 2 surface, utilizing the height difference between the protrusion 502 and the bottom inner wall of the separation protection box 401, the rubber roller 403 can bring the separation screen drum 402 up and down as a whole, and repeat the cycle, thereby causing the separation screen drum 402 to vibrate, which is beneficial for shaking off the particulate impurities adhering to the inner wall of the separation screen drum 402, avoiding the particulate impurities from clogging the mesh, and improving the adsorption effect of dust-like suspended impurities. In addition, the power is provided in a non-energy way, which effectively reduces the energy consumption of the device during the impurity recovery period;

[0053] The dust-like suspended impurities entering the dust collecting component 601 will eventually enter the dust bag 602. The dust bag 602 can collect the dust-like suspended impurities and effectively remove the particulate impurities with diameters ranging from a few microns to tens of microns in the dust-like suspended impurities, thereby significantly improving the air quality of the working environment and the surrounding environment and reducing the harm to human health. When there are particulate impurities in the dust-like suspended impurities that are not completely filtered by the separation sieve 402, the particulate impurities entering the dust collecting component 601 will adhere to the surface of the sedimentation bottom plate 603 under the action of gravity. Movement, by opening a groove on the top of the sedimentation bottom plate 603, the moving speed of the particulate impurities can be reduced, and the particulate impurities in the moving state can be intercepted, so that the particulate impurities can fall evenly on the surface of the groove, and then, by using the through hole 604 and the square groove 605, the intercepted particulate impurities can fall from the inside of the dust collecting component 601 to the inside of the sedimentation tank 802, which plays a role of secondary separation. Compared with the method of directly using the dust bag 602 to collect impurities, the particulate impurities in the impurities are first separated and then wetted to ensure the impurity filtering effect, which helps to improve the separation effect;

[0054] In addition, the particulate impurities falling from the discharge hole 4011 will first pass through the guide barrel 701, and the contour shape of the guide barrel 701 is wide at the top and narrow at the bottom, so that the particulate impurities can be concentrated, which is convenient for the subsequent spraying work. As the particulate impurities fall from the bottom opening of the guide barrel 701, the circulating water pump 704 is started, so that the circulating water pump 704 draws water from the inside of the circulation pool 801 and sprays it through the spray pipe head 703. At the same time, the circulating water pump 704 can also be connected to an external pipeline to supplement the water volume in the circulation pool 801, so that the separated particulate impurities and some dust-like suspended impurities that are not completely separated are wetted after contacting with water, and the wetted particulate impurities can smoothly fall into the circulation pool 801, and the remaining dust-like suspended impurities can pass through the square groove 605 and the through hole 60 4 enters the dust bag 602 to remove particulate impurities in the dust-like suspended impurities for the second time. The isolation cover 705 can be used to separate the water containing particulate impurities in the circulation pool 801 from the water suction port of the circulation water pump 704, thereby preventing the circulation water pump 704 from sucking in particulate impurities, which helps to ensure the stability of the circulation water pump 704 and improve its service life. In addition, the circulation water pump 704 is used to circulate the water in the circulation pool 801 and spray it out through the spray pipe head 703, which can save water. The particulate impurities collected in the circulation pool 801 flow into the sedimentation tank 802 under the effect of the height difference between the circulation pool 801 and the sedimentation tank 802. When a certain amount of impurities accumulate, the staff can collect the particulate impurities in the sedimentation tank 802 uniformly to complete the recycling work;

[0055] Since various auto parts are of different sizes, before spraying, the staff holds the two damping handles 903 and presses them down at the same time, so that the two damping handles 903 with the adjustment covers 902 are flipped at the end of the support rod 901 toward the side close to the collecting cover 302, and the damping effect of the damping handles 903 is used to fix the adjustment covers 902, so that the diameter of the space enclosed by the bottom of the two adjustment covers 902 is increased, thereby improving the protection range of the bottom of the collecting cover 302, which is beneficial to improving the protection effect of impurities during spraying of larger auto parts and avoiding impurities from overflowing. For smaller auto parts, the opposite operation is required, which improves the applicability of the device.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
