[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] 1. The utility model adopts a zoned and closed hierarchical exhaust structure. When the paint impregnation gas overflows from the vacuum paint impregnation chamber, the workshop gas concentration detector in the working area detects the change in the concentration of organic matter in the air and sends a signal to the control host. The control host feeds back the signal to the variable frequency blower and the electric control air duct valve in the working area, opens the electric control air duct valve and increases the power of the variable frequency blower, thereby extracting the polluted gas in the working area along the electric control air duct valve and the exhaust main pipe.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely 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.
[0025] See also Figure 1-4 The utility model provides an embodiment of a vacuum varnishing odor sealing structure, comprising a closed chamber 1, an access door 6 being installed on the outer wall of the closed chamber 1, a peripheral area 2 being provided inside the closed chamber 1, a working area 3 being provided on one side of the peripheral area 2, a vacuum varnishing chamber 7 being installed inside the working area 3, and an operating door 8 being installed on the outer wall of the vacuum varnishing chamber 7;
[0026] Also includes:
[0027] A partition 4 is installed between the peripheral area 2 and the working area 3. An isolation door 5 is installed on the partition 4, and two isolation doors 5 are provided. One-way ventilation fans (not shown in the figure) are provided at the front ends of the peripheral area 2 and the working area 3;
[0028] An exhaust main pipe 9 is installed above the vacuum immersion paint chamber 7. One end of the exhaust main pipe 9 is connected to the inner cavity of the vacuum immersion paint chamber 7, and the other end of the exhaust main pipe 9 passes through the partition 4 and extends to the outside of the closed chamber 1.
[0029] The branch pipe 14 is installed on the outer wall of the exhaust main pipe 9. There are two branch pipes 14, and the two branch pipes 14 are respectively arranged inside the peripheral area 2 and the working area 3. An extension pipe 11 is installed at one end of the branch pipe 14, and an electric-controlled air duct valve 12 is installed at one end of the extension pipe 11.
[0030] See also Figure 2A variable frequency fan connector 10 is installed at the other end of the extension tube 11, and the extension tube 11 is connected to the variable frequency blower through the variable frequency fan connector 10. A workshop gas concentration detector 15 is installed inside the peripheral area 2 and the working area 3. The variable frequency blower has multi-stage adjustment and can adjust the power according to the number of openings of the electric-controlled air duct valve 12. The model of the workshop gas concentration detector 15 is SK / MIC-600-TVOC-Y, which can be used to detect the concentration of volatile organic compounds in the workshop air, thereby determining whether the air is polluted.
[0031] See also Figure 4 The output end of the workshop gas concentration detector 15 is electrically connected to the input end of the control host, and the output end of the control host is electrically connected to the input end of the electric control duct valve 12 and the variable frequency blower. There are two workshop gas concentration detectors 15, which are located in the peripheral area 2 and the working area 3 respectively, and can be used to independently detect the air quality of the two areas. When people enter and exit the vacuum immersion paint room 7, the immersion paint gas overflows from the room. At this time, the workshop gas concentration detector 15 in the working area 3 detects the change in the concentration of organic matter in the air and sends a signal to the control host. The control host feeds back a signal to the variable frequency blower and the electric-controlled air duct valve 12 in the working area 3, opens the electric-controlled air duct valve 12 and increases the power of the variable frequency blower, thereby extracting the polluted gas in the working area 3 along the electric-controlled air duct valve 12 along the exhaust main pipe 9. When the polluted gas further overflows to the peripheral area 2, the gas concentration detector 15 in the peripheral area 2 will further send a signal to the control host, opens the electric-controlled air duct valve 12 in the peripheral area 2 and further increases the power of the variable frequency blower, thereby realizing zoned and graded exhaust control.
[0032] See also Figure 3 An arc-shaped plate 16 is installed inside the extension tube 11. There are multiple arc-shaped plates 16, and the multiple arc-shaped plates 16 are equidistantly distributed. If the gas flows along the exhaust main pipe 9 to the extension tube 11, the arc-shaped concave structure of the arc-shaped plate 16 will cause certain obstruction to the gas flow, thereby avoiding gas backflow during exhaust to a certain extent. A guide protrusion 17 is installed at the front end of the arc-shaped plate 16. When the gas enters the extension tube 11 and flows toward the exhaust main pipe 9, the arc-shaped plate 16 cooperates with the guide protrusion 17 at the front end to divert the gas. The diverted gas re-converges after passing through the arc-shaped plate 16, which increases the flow speed of the gas in the extension tube 11 to a certain extent and ensures the exhaust efficiency.
[0033] See also Figure 2 Two reinforcing rods 13 are installed between the extension pipe 11 and the exhaust main pipe 9, and the two ends of the reinforcing rod 13 are welded to the extension pipe 11 and the exhaust main pipe 9 respectively. The reinforcing rod 13 ensures the structural strength of the extension pipe 11 and the exhaust main pipe 9.
[0034] Working principle: When the equipment in the vacuum varnishing room 7 is running, the variable frequency blower at the end of the exhaust main pipe 9 is in the normally open state, and the polluted gas generated by vacuum varnishing is discharged along the exhaust main pipe 9. When people enter and exit the vacuum varnishing room 7, the varnishing gas overflows from the room. At this time, the workshop gas concentration detector 15 in the working area 3 detects the change in the concentration of organic matter in the air and sends a signal to the control host. The control host feeds back the signal to the variable frequency blower and the electric control air duct valve 12 in the working area 3, opens the electric control air duct valve 12 and increases the power of the variable frequency blower, thereby extracting the polluted gas in the working area 3 along the electric control air duct valve 12 along the exhaust main pipe 9. When the polluted gas further overflows to the peripheral area 2, the gas concentration detector 15 of the peripheral area 2 will further send a signal to the control host, open the electric-controlled air duct valve 12 of the peripheral area 2, and further increase the power of the variable-frequency blower, thereby realizing zoned and graded exhaust control. When exhausting, the arc plate 16 and the guide protrusion 17 arranged in the extension pipe 11 cooperate to divert the gas. The diverted gas re-converges after passing through the arc plate 16, which increases the flow speed of the gas in the extension pipe 11 to a certain extent and ensures the exhaust efficiency. At the same time, when the gas in the pipe refluxes, the groove structure of the arc plate 16 will cause certain obstructions to avoid the contaminated gas in the exhaust main pipe 9 from flowing back and overflowing along the extension pipe 11.
