Air monitoring device for spraying workshop

Abstract

The invention relates to an air monitoring device for a spraying workshop. An air compressor and a plurality of paint spraying heads are arranged in the spraying workshop. The paint spraying heads areconnected with the air compressor. A bypass pipe is arranged at an outlet of the air compressor. A pressure test unit and an air quality monitoring unit are connected to the tail end of the bypass pipe and are located in a control center. Compared with the prior art, the invention has the advantages that air coming out of the air compressor is delivered to the control center through the bypass pipe, and then the pressure and impurity content of the air are monitored through the pressure test unit and the air quality monitoring unit, so that the air quality in the spraying workshop is guaranteed, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of spraying workshops, in particular to an air monitoring device for spraying workshops. Background technique [0002] In the production process of wooden furniture, it is necessary to color and spray paint the board. The current painting process is usually carried out in the spray booth. The painting room is to spray paint on the treated workpiece in an air-filtered airtight room. The method of spray painting is to use compressed air to atomize the paint, and then evenly adhere to the surface of the furniture. In the actual operation process, due to the large pollution in the spray booth, the automatic spraying is usually realized by the way of controlling the movement of the spray head by the mechanical arm. However, in the process, once there is a problem in the spray booth, it is difficult for workers to obtain information at the first time. For example, when the compressed air is blocked, on the one h...

Problems solved by technology

However, in the process, once there is a problem in the spray booth, it is difficult for workers to obtain information at the first time. For example, when the compressed air is blocked, on the one hand, the quality of the spray paint will be reduced, and on the other hand, it may cause an explosion due to excessive pressure, causing danger.

Therefore, it is necessary to realize real-time monitoring of the compressed air pressure in the spray booth; another example is the air quality in the spray booth, which will also seriously affect the quality of the spray paint.

In addition, due to the high corrosiveness of the air in the spray booth, if the sensor is directly installed in the spray booth, the life of the sensor is very short and the cost is high
