Detailed Description
In the prior art, paint spray booths for finish-painting repair of heat-insulating decorative boards are composed of a manual wiping area, a manual paint spray area, a robot automatic paint spray area, a manual paint repair area, and a drying area, and are arranged in sequence from upstream to downstream (as shown in fig. 1). The following description is made in detail with reference to specific embodiments, and fig. 1 shows a schematic structural diagram of a first implementation manner of the air supply and exhaust system of the paint spray booth with heat-preservation decorative boards of the present invention, which mainly comprises a fresh air conditioner 1, a first circulating air conditioner 2, a second circulating air conditioner 3, a third circulating air conditioner 4, a fourth circulating air conditioner 5, and so on, wherein independent air supply is performed for an artificial cleaning area, a manual painting area, an automatic painting area of a robot, a manual painting area, and a drying area by means of the fresh air conditioner 1, so as to ensure air quality and temperature and humidity in each area. It should be emphasized that the air inlets of the first circulating air conditioner 2, the second circulating air conditioner 3, the third circulating air conditioner 4 and the fourth circulating air conditioner 5 are respectively communicated with the manual wiping area, the manual painting area, the manual paint supplementing area and the drying area, and the air outlets of the first circulating air conditioner, the second circulating air conditioner, the third circulating air conditioner and the fourth circulating air conditioner are respectively communicated with the automatic painting area of the robot. Therefore, the air supply and exhaust of the paint spray booth are recycled, the fresh air supply amount is cyclically replaced in a local system of the paint spray booth, the energy consumption caused by fresh air updating is greatly reduced, and the cost for repairing the finish paint of the heat-insulation decorative board is reduced.
The starting point of the technical scheme is that the manual wiping area, the manual painting area and the manual paint repair area need to be entered and participated by workers, fresh air needs to be supplied into the manual wiping area, and personal safety of the workers is guaranteed. The robot automatic paint spraying area does not need workers, and the requirement standard for air toxicity is low, so that the air exhausted from the manual wiping area, the manual paint spraying area, the manual paint replenishing area and the air drying area can be input into the robot automatic paint spraying area again for recycling.
Fig. 2 shows a schematic structural diagram of a second embodiment of the air supply and exhaust system of the paint spray booth with middle heat-insulating decorative boards, which is different from the first embodiment in that: the air supply and exhaust system is additionally provided with a circulating gas pretreatment part 6 which is communicated among the first circulating air conditioner 2, the second circulating air conditioner 3, the third circulating air conditioner 4, the fourth circulating air conditioner 5 and an automatic paint spraying area of the robot. The circulating gas pretreatment unit 6 is composed of a primary filter element 61, a heating element 62, a spray humidification element 63, and a secondary filter element 64, which are arranged in this order along the gas flow direction. It should be noted that the filtering of large particle impurities in the air is realized by means of the primary filter component 61, then the humidifying and temperature-adjusting treatment is performed by means of the heating component 62 and the spray humidifying component 63, and finally the final filtering of the air is realized by means of the intermediate filter component 64.
As a further optimization of the air supply and exhaust system of the insulated decorative panel painting booth, the heating unit 62 includes a pipe 621 through which air flows, an electric heating wire 622, and an asbestos insulation layer 623. Wherein, the electric heating wire 622 is wrapped between the pipe 621 and the asbestos insulation layer 623, and spirally wound on the outer side wall of the pipe 621 (as shown in fig. 4). The pipe 621 is preferably made of a material having high thermal conductivity and transparency. Thus, the air has a high temperature rise rate effectively, and the energy consumption is reduced to the maximum extent.
As is known, when air is normally circulated in the pipe 621, the air generally takes on a laminar flow, which is not beneficial to heat exchange with the inner wall of the pipe 621, and in order to improve the heat exchange efficiency of the air in the pipe 621, a plurality of spoilers 624 (shown in fig. 4) which are staggered up and down may be fixed in the inner cavity of the pipe 621 along the length direction of the pipe 621. The existence of the spoiler 624 can effectively break the laminar state of the air and improve the temperature rise speed of the air.
Fig. 3 shows a schematic structural diagram of a third embodiment of the air supply and exhaust system of the paint spray booth with middle heat-insulating decorative boards, which is different from the first embodiment in that: the air supply and exhaust system is additionally provided with an exhaust machine 7 so as to discharge tail gas in time. The exhauster 7 is disposed at an exhaust port of the robot automatic painting area. In addition, the air supply and exhaust system also comprises a paint mist catching device 8 and a VOC treatment device 9 which are sequentially arranged at the downstream of the exhauster 7, so that tail gas exhausted from a paint spraying chamber is effectively cleaned, and the pollution to the atmosphere is avoided.
Finally, a photochemical decomposition section 10 composed of a transparent gas flow duct and a nano photocatalyst layer fixed to the inner wall of the transparent gas flow duct may be provided between the mist trap 8 and the VOC treatment device 9. It is known that the nano photocatalyst layer can generate a photocatalytic reaction similar to photosynthesis under the irradiation of natural light, and then generate free hydroxyl and active oxygen with extremely strong oxidizing power, and the nano photocatalyst layer has a very strong photo-oxidation-reduction function and can decompose tail gas circulating in a pipeline, so that the purification rate and the purification effect of organic waste gas are improved.
It is known that the nano-sized titanium dioxide photocatalyst layer has the characteristics of strong oxidizing ability, stable chemical properties, no toxicity and the like, and therefore, the nano-sized titanium dioxide photocatalyst layer is preferably a nano-sized titanium dioxide photocatalyst layer.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
