[0043] The top of the room body 1 is provided with a discharge port 13 connected to the paint spraying space, and the discharge port 13 is usually located at the center of the top of the room body 1. The ventilation device 2 is used to guide the air outside the room body 1 to enter the paint spraying space from bottom to top through the first air inlet channel 11 and the second air inlet channel 12, and discharge from the discharge port 13. The ventilation device 2 is usually installed at the discharge port 13. The ventilation device 2 powerfully and continuously sucks the paint mist generated during the painting process, so that the paint mist in the room body 1 is quickly discharged from the discharge port 13. According to the principle of fluid mechanics, the air is taken in from the bottom to the top on the left and right sides of the room body 1, and the exhaust is upward on the top of the room body 1, which can quickly discharge the exhaust gas. After the operator holds the spray gun to spray paint, the paint mist can be greatly reduced, the health impact of the paint mist on the operator can be reduced, and the quality of the paint spraying and the efficiency of the paint spraying work can be improved. In the paint spraying room, especially the spray gun nozzle and the surrounding area of ​​the painted workpiece can be replaced with fresh air in time, and the direct effect is to eliminate the paint mist in the paint spraying room infinitely close.

[0044] Specifically, the ventilation device 2 includes a fan and an exhaust pipe, the fan is arranged in the exhaust pipe, and the exhaust pipe is connected to the discharge port 13. When the fan is started, the discharge port 13 generates a large suction force, and the external air enters the painting space from bottom to top through the first air inlet channel 11 and the second air inlet channel 12, and then is discharged from the discharge port 13 at the top of the painting space.

[0045] The clean paint spraying room further comprises a conveying mechanism 3, which is arranged along the first air inlet passage 11, the paint spraying space and the second air inlet passage 12. The conveying mechanism 3 can adopt a linear single assembly line structure or a ring-shaped double assembly line structure.

[0046] Specifically, the conveying mechanism 3 includes an annular support track 31, an annular conveying chain 32 and a driving device 33. The annular support track 31 sequentially passes through the first air inlet channel 11, the paint spraying space and the second air inlet channel 12. The annular conveying chain 32 is arranged along the annular support track 31. The annular conveying chain 32 is provided with a hanging part. The driving device 33 is used to drive the annular conveying chain 32 to move along the annular support track 31. Among them, the driving device 33 includes a driving motor, and the driving motor is connected to a driving gear, and the driving gear and the annular conveying chain 32 are meshed with each other. The workpiece is arranged on the hanging part, and the driving device 33 is used to drive the annular conveying chain 32 to circulate along the annular support track 31 to realize the input, painting and output of the workpiece. The operator can control the running speed, pause or operation of the annular conveying chain 32 to complete the painting.

[0047] Preferably, the ring-shaped conveying chain 32 includes a first upward feeding section, a first paint spraying section, a first downward discharging section, a second upward feeding section, a second paint spraying section and a second downward discharging section which are connected end to end; the first upward feeding section and the second downward discharging section are both arranged along the first air inlet channel 11; the first paint spraying section and the second paint spraying section are both arranged in the paint spraying space; the first downward discharging section and the second upward feeding section are both arranged along the second air inlet channel 12; and an infrared drying device is provided above the first downward discharging section and the second downward discharging section.

[0048] The room body 1, the first air inlet channel 11 and the second air inlet channel 12 are all provided with partitions, thus forming two production lines. The room body 1 is divided into two compartments, front and back. The two compartments are relatively independent spray painting rooms with the same functions, sharing the conveying mechanism 3, the first air inlet channel 11 and the second air inlet channel 12. Two shifts of personnel can work at the same time, or only one room can be used and the other spray painting room can be idle. The two spray painting rooms each have an upward channel, a downward channel and a ladder 15, and the two opposite sides of the spray painting room are set to be the A side and the B side respectively. The assembly line of the front spray painting room is A up and B down, and the assembly line of the rear spray painting room is B up and left A. The infrared drying device is built into the downward channel to quickly dry the surface paint surface after spraying.

[0049] The hanging member includes a hanging ring 34, which is fixed on the endless conveying chain 32. Preferably, the hanging member also includes a hanging frame 35, and a hook 36 is rotatably provided on the top of the hanging frame 35, and the hook 36 is hung on the hanging ring 34. For some workpieces that can be hung directly, they can be hung directly on the hanging ring 34; for some workpieces that cannot be hung directly, they can be placed directly on the hanging frame 35, and the hanging frame 35 can rotate 360 ​​degrees using the hook 36, which is convenient for painting the workpiece.

[0050] In many cases, some workpieces (such as U-bolts of railway embedded parts, end cover casings of motor factories, electric vehicle racks, etc.) do not need to be placed on the hanging rack 35, but can be directly hung on the hanging ring 34 (the hanging ring 34 can also be designed to rotate 360 ​​degrees) for transportation and painting; there are also auxiliary workers at both ends of the suspension assembly line in the paint spraying room, who are responsible for hanging and unloading the workpieces respectively. The workpieces are placed on special process vehicles. The unpainted workpieces are sent to the upper channel entrance by the process vehicle, and the auxiliary workers hang them on the hanging assembly line. After painting, the workpieces are unloaded by the auxiliary workers at the lower channel entrance.

[0051] In a specific embodiment, the discharge port 13 is equipped with a purification device. The purification device purifies the exhaust gas from the discharge port 13 to reduce environmental pollution. Specifically, the purification device includes an activated carbon purification mechanism 4 and a water mist purification mechanism 5, and the activated carbon purification mechanism 4 and the water mist purification mechanism 5 are both used to purify the gas discharged from the discharge port 13. The present invention utilizes the activated carbon purification mechanism 4 and the water mist purification mechanism 5 to purify the exhaust gas, thereby reducing the external emission of toxic gases and ensuring that the factory's environmentally friendly emissions meet high-quality standards. The fan inlet is connected to the exhaust duct on the top of the room, and the fan outlet is connected to the inlet of the activated carbon purification mechanism 4; multiple activated carbon purification mechanisms 4 can be connected in series or in parallel, with the aim of purifying the paint mist more purely.

[0052] Among them, the activated carbon purification mechanism 4 includes an activated carbon purification box 41, which is provided with an air inlet 42 and an air outlet 43. The air inlet 42 is connected to the outlet of the fan. After the exhaust gas of the room body 1 is discharged from the exhaust port 13, it enters the inside of the activated carbon purification box 41 through the air inlet 42, and is discharged from the air outlet 43 after purification. A rotating shaft 44 is rotatably provided in the activated carbon purification box 41, and a plurality of activated carbon filter pages are provided on the peripheral side of the rotating shaft 44. The rotating shaft 44 is connected to a driving member, and the driving member is used to drive the rotating shaft 44 to rotate so as to switch different activated carbon filter pages to the position of the air inlet 42 of the activated carbon purification box 41. Preferably, the air inlet 42 and the air outlet 43 are relatively arranged on both sides of the activated carbon purification box 41, and the air inlet 42 and the air outlet 43 are both offset from the center of the activated carbon purification box 41. A paint mist monitoring point is set at each inlet and outlet of the activated carbon purification mechanism 4, and it is determined whether to rotate and shift the activated carbon filter page or replace all the activated carbon filter pages according to the monitoring point.

[0053] When the activated carbon purification mechanism 4 is used, the position of each activated carbon filter page is rotated and adjusted one by one according to the working time of each activated carbon filter page placed at the air inlet 42, so that each activated carbon filter page can be fully utilized to achieve effective purification of the exhaust gas in the paint spraying room. The present invention has a simple structure, and through the rapid switching of the activated carbon filter pages, it helps the purification device to maintain a good exhaust gas treatment capacity for a long time and improve the exhaust gas purification effect. The activated carbon purification mechanism 4 has a number of activated carbon filter pages to form an activated carbon filter layer (each layer is equivalent to a filter wall). The paint mist encounters the front row of activated carbon filter pages from the air inlet, and is filtered one by one by the activated carbon filter pages behind. When it reaches the air outlet, it has become relatively qualified air, and there is still a little odor or impurities, and then enters the water mist purification mechanism 5 for filtration.

[0054] Specifically, the activated carbon filter page includes a filter cartridge 45, and the filter cartridge 45 is filled with activated carbon. After the activated carbon filter page is used for a period of time, the activated carbon can be replaced. The driving member includes an operating rod 46, and the operating rod 46 is rotatably connected to one end of the rotating shaft 44 extending to the outside of the activated carbon purification box 41. The surface of the activated carbon purification box 41 is provided with a plurality of fixing buckles 47 arranged in a ring shape, and the fixing buckle 47 is used to fix the operating rod 46. The operating rod 46 controls the rotating shaft 44 to rotate a certain angle. After completing the switching of the activated carbon filter page, the operating rod 46 is stuck on the fixing buckle 47 to keep the operating rod 46 and the rotating shaft 44 in a fixed state. The activated carbon filter page of the air inlet 42 is the front position for removing paint mist. The activated carbon filter page is rotated irregularly, and the purpose is to place multiple activated carbon filter pages in turn at the front to remove paint mist. After using it for a period of time, depending on the filtering situation, the top cover of the activated carbon purification box 41 is removed and replaced with a new activated carbon filter page. The present invention rotates the activated carbon filter pages, so that each activated carbon filter page can filter paint mist on both sides, which is superior to the existing drawer activated carbon box, making full use of the activated carbon in each activated carbon filter page to fully exert the function of absorbing paint mist particles.

[0055] In a specific embodiment, the purification device further includes a water mist purification mechanism 5, which is connected to the air outlet 43 of the activated carbon purification box 41. The exhaust gas from the paint spraying room is purified by the activated carbon purification mechanism 4 and the water mist purification mechanism 5 in turn, thereby improving the exhaust gas purification effect and minimizing the pollution of the exhaust gas to the environment.

[0056] Specifically, the water mist purification mechanism 5 includes a water mist purification chimney 51, the side wall of the water mist purification chimney 51 is provided with a lateral inlet 52 connected to the air outlet 43, the top of the water mist purification chimney 51 is provided with a water mist ejector 53, and the bottom of the water mist purification chimney 51 is provided with a purification pool 54. Preferably, a water supply pipe is provided between the purification pool 54 and the water mist ejector 53, and a driving pump is provided on the water supply pipe to realize the recycling of water resources. A filter element is provided at the inlet end of the water supply pipe, and the water supply pipe delivers pressurized clean water to the water mist ejector. The purification pool 54 is a pool for filtering waste residues of the deposited paint mist chimney, and the purification pool 54 needs to be cleaned and the filter element replaced from time to time.

[0057] A first guide plate 55 and a second guide plate 56 are provided in the water mist purification chimney 51. The first guide plate 55 is used to guide the gas from the side inlet 52 to move toward the water mist injector 53; the second guide plate 56 is arranged below the first guide plate 55, and the second guide plate 56 is used to guide the liquid inside the water mist purification chimney 51 into the purification water pool 54.

[0058] The waste gas filtered by the activated carbon purification mechanism 4 may still contain a small amount of harmful substances. The waste gas enters the water mist purification chimney 51 through the side inlet 52. The first guide plate 55 guides the waste gas to flow to the upper part of the water mist purification chimney 51. An annular water mist injector 53 is provided on the top of the water mist purification chimney 51. The annular tube of the water mist injector 53 is densely covered with fine nozzles along the circumferential direction. The fine streams are ejected to collide with each other or spray onto the inner wall of the water mist purification chimney 51, splashing to form dense water mist. The upward exhaust gas and the falling water mist blend together, and the exhaust gas separates pure air and overflows into the water mist purification chimney 51 to be discharged into the atmosphere, while the trace particles in the exhaust gas follow the water mist and condense into water droplets and fall to the lower part of the water mist purification chimney 51, and then flow along the second guide plate 56 to the purification pool 54. The water surface of the purification pool 54 submerges the lower mouth of the water mist purification chimney 51, so the exhaust gas will not be discharged from the lower part of the water mist purification chimney 51, and only the smoke particles will flow into and settle to the bottom of the pool, and the bottom of the pool only needs to be cleaned regularly.

[0059] In a specific embodiment, a support frame 14 is provided at the bottom of the room body 1. The support frame 14 raises the room body 1, which is conducive to air intake. A ladder 15 is connected to the room body 1 to facilitate operators to enter the painting space for painting operations.

[0060] The present invention innovatively provides an environmentally friendly paint spraying room, which elevates the room body 1 to the upper layer, the exhaust port 13 is at the top of the room body 1, the air inlet is located at the lower layer of the room body 1, and there is no overflow port in the surrounding space parallel to the paint spraying space. According to the principle of fluid mechanics, the airflow in the room body 1 is smooth, and the operators are rarely affected by paint mist pollution. The direct effect is to improve the quality of paint spraying, increase the mass production of paint spraying per unit time, and reduce the consumption of paint. Because, in a clear environment, the operator's vision is not blurred, the paint spraying point is accurately grasped, and excessive blind spraying or blurred spraying operations are avoided. Compared with the field spreading method, more than 35% of paint is saved. In addition, the operator changes from full-field active spraying to fixed-point operation, avoiding the waste of time running back and forth, so that the work efficiency is improved by more than 30%, the factory's environmental protection emissions are of high quality and meet the standards, the working environment is greatly improved, and the phenomenon of randomly placing workpieces on the ground in the factory is changed, so that the objects are placed in an orderly manner and the operation channel is smooth.
