Problems solved by technology
[0002] The spraying process often produces a large amount of exhaust gas during the processing process. The exhaust gas contains a large amount of paint particles, which will not only be inhaled into the human body and affect the health of the operator, but also be deposited on the processing equipment and auxiliary equipment to cause damage to the equipment.
In the existing technology, there is also the exhaust gas generated during the spraying process by means of fan suction, but because the coating used for spraying has high viscosity and high strength after curing, it is difficult to clean when it adheres to the fan blades. The fans in the technology often need to clean and maintain the blades frequently, and cleaning is difficult at the same time, and the cost of directly replacing the fan blades is too high, which is not conducive to the promotion of manufacturers

Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0018] The invention provides a waste gas recovery method of a spraying line, which comprises
[0019] Step 1. Direct the nozzle on the spraying line toward the entrance 1.1 of the front chamber 1, so that the exhaust gas generated by the nozzle spraying the workpiece enters the front chamber 1;
[0020] Step 2. Turn on the fan 3 communicating with the rear chamber 2 to extract the air in the rear chamber 2. A water tank 4 is provided at the bottom of the rear chamber 2, and the water tank 4 extends horizontally to the front chamber 1 The bottom of the front chamber 1 and the rear chamber 2 is provided with a partition 5, and there is a gap 6 between the bottom of the partition 5 and the horizontal surface in the water tank 4, and the air in the front chamber 1 passes through the gap 6 Enter back chamber 2;
[0021] Step 3, turn on the water ...

The invention discloses a waste gas recycling method for a spraying and coating line. The waste gas recycling method for the spraying and coating line is characterized by comprising the following steps: step 1 of arranging a nozzle on the spraying and coating line to face towards a position where an entry of a front chamber is located, so that waste gas produced by spraying and coating workpieces enters the front chamber; step 2 of starting a fan that is communicated with a rear chamber to pump away air in the rear chamber, wherein a water tank is arranged at the bottom of the rear chamber, and extends to the bottom of the front chamber along a horizontal direction, a separating plate is arranged between the front chamber and the rear chamber, a gap is reserved between the lower part of the separating plate and the horizontal plane of the inside of the water tank, and the air in the front chamber enters the rear chamber through the gap; and step 3 of starting a water pump to realize circulation of waste water in the water tank and a water treatment system. The waste gas recycling method for the spraying and coating line disclosed by the invention has the advantages of good waste gas recycling effect, low maintenance frequency and low maintenance cost.
