Description

Technical Field

[0001] The utility model relates to the technical field of spraying and drying equipment, in particular to a spraying part heating and drying device for a PVC spray booth. Background Technique

[0002] At present, for the workpieces processed by spraying in a spray booth, corresponding heating and drying equipment is required for post-treatment. With the continuous development of spraying technology in recent years, the heating and drying equipment suitable for use in spray booths is also developing towards diversification and high quality. For example, the patent document with the application number 201821187941.0 proposes "a spraying part heating and drying device for a spray booth of the present utility model. An air outlet pipe is arranged at the bottom of the spray booth, and the air outlet pipe is connected to a plasma waste gas purifier. The plasma waste gas purifier can decompose the paint mist waste gas in the spray booth in a very short time and carry out subsequent various reactions to achieve the purpose of degrading pollutants, making the waste gas in the spray booth meet the discharge standards and reducing environmental pollution. The air outlet of the plasma waste gas purifier is connected to the air inlet of a blower through a circulation pipe. Since the gas discharged from the spray booth still has residual heat, the discharged gas is reused to enter the blower to heat the spraying parts in the spray booth again, reducing power consumption and improving the utilization rate of resources", "Filter layers are provided at the air inlet and air outlet of the air inlet pipe 3. The filter layer 4 includes two metal mesh layers, and a filter cotton layer is clamped between the two metal mesh layers. The air flow entering the blower 2 is filtered by the filter layer 4 before entering the spray booth 1 to prevent solid impurities or ash layers contained in the air flow from entering and polluting the surface of the spraying parts".

[0033] Working principle:

[0034] Embodiment 1

[0035] When the air quality of the use environment is good, open the valves of the first air supply valve pipe 10 and the third air supply valve pipe 12, start the blower 2, and the blower 2 conveys the outside air to the interior of the first processing box 5, and then the filter support assembly 7 and the filter cotton layer 8 arranged inside the first processing box 5 are filtered and processed to enter and exit the dust removal and purification, and the purified air enters the heating assembly 3 through the first air supply valve pipe 10 and the third air supply valve pipe 12, and then the heating assembly 3 heats the purified air, and the heated air enters the interior of the paint spraying room 1 through the main air duct 4, and the sprayed workpieces inside the paint spraying room 1 are heated and dried.

[0036] Embodiment 2

[0037] When the air quality of the use environment is poor, the valve of the first gas transmission valve pipe 10 is opened, the valve of the third gas transmission valve pipe 12 is closed, and the valve of the second gas transmission valve pipe 11 is opened, and the blower 2 is started, and the outside air is transported to the inside of the first treatment box 5 by the blower 2, and then the air is filtered and purified by the filter support assembly 7 and the filter cotton layer 8 arranged inside the first treatment box 5, and the purified air enters the inside of the second treatment box 6 through the first gas transmission valve pipe 10 and the transition pipe 13. Similarly, the second filtering is performed under the action of the filter support assembly 7 and the filter cotton layer 8 arranged inside the second treatment box 6;

[0038] The second purified air enters the interior of the heating component 3 through the second air supply valve pipe 11 and the third air supply valve pipe 12, and the purified air is then heated by the heating component 3. The heated air enters the interior of the paint spraying room 1 through the main air duct 4 to heat and dry the sprayed workpieces inside the paint spraying room 1.

[0039] Embodiment 3

[0040] To judge the quality of the purified air, open the valves of the first air delivery valve pipe 10 and the third air delivery valve pipe 12, start the blower 2, and let the blower 2 deliver the outside air into the interior of the first treatment box 5. Then, the air enters and exits the dust removal and purification process under the filtration of the filter support assembly 7 and the filter cotton layer 8 arranged inside the first treatment box 5. The purified air enters the heating assembly 3 through the first air delivery valve pipe 10 and the third air delivery valve pipe 12. At the same time, open the valves of the two branch valve pipes 143, and the purified air flows in a circular motion inside the transition box 141 through the two branch valve pipes 143, and then is captured and detected by the dust sensor 142, and data on the quality of the purified air is output.

[0041] Example 4

[0042] For the replacement of the filter cotton layer 8 inside the first treatment box 5 and the filter cotton layer 8 inside the second treatment box 6, the equipment can be paused and replaced synchronously, that is, start the brake servo motor 91 and the two electromagnetic chucks. The brake servo motor 91 drives the two straight tooth plates 93 through the meshing of the gear 92, so that the two straight tooth plates 93 drive the two filter support assemblies 7 to move away from each other through the transmission crank rods 94 connected to them respectively until the filter cotton layer 8 gives way to the first treatment box 5 or the second treatment box 6. Turn the nut, take out the used filter cotton layer 8, then put on the new filter cotton layer 8, and reset and lock the nut.

[0043] Or, without pausing the equipment, replace them individually, that is, start the brake servo motor 91 and a designated electromagnetic chuck. The brake servo motor 91 drives the two straight tooth plates 93 through the meshing of the gear 92, so that the two straight tooth plates 93 drive a designated filter support assembly 7 to move linearly through the transmission crank rods 94 connected to them respectively until the filter cotton layer 8 gives way to the first treatment box 5 or the second treatment box 6. Turn the nut, take out the used filter cotton layer 8, then put on the new filter cotton layer 8, and reset and lock the nut.

[0044] And if replacing the filter cotton layer 8 inside the first treatment box 5, conduct air delivery according to the flow channel of Example 2, and if replacing the filter cotton layer 8 inside the second treatment box 6, conduct air delivery according to the flow channel of Example 1.
