Water curtain air filtering device for spraying

Abstract

The invention relates to a water curtain air filtering device for spraying, comprising an operating region and a workbench arranged in the operating region, wherein a water curtain wall is arranged on a vertical surface at the front part of the operating region, an overflow pipe is arranged above the water curtain wall, and a water collecting tank is arranged below the water curtain wall. The water curtain air filtering device is characterized in that the vertical surfaces at two sides of the operating region and the vertical surface on the top of the operating region are of closed structures, the lower edge of the water curtain wall is suspended above the water collecting tank, a folded edge is arranged at the lower edge of the water curtain wall, and the folded edge is at least provided with two rows of spraying holes distributed alternately; an airflow channel is arranged at the back of the water curtain wall, and an exhaust fan is arranged at the top of the airflow channel; and an overflow trough is arranged on the surface of the workbench, close to one side of the water curtain wall, water overflowing from the overflow trough falls into the water collecting tank, and the water collecting tank is communicated with the overflow pipe and the overflow trough by a water pump and a pipe. The water curtain air filtering device has the characteristics of being smart in conception and simple in structure and integrating water curtain adsorption and spraying filtering, is especially suitable for use in the paint spraying process, and can adsorb and filter a great amount of paint mist suspending in air, so as to reduce pollution of direct exhaust to air.

Description

Technical field: [0001] The invention belongs to the field of water curtain dedusting air filtration, and in particular relates to a spraying water curtain air filtration device, which can remove a large amount of suspended dust mist generated during the spraying process and play the role of filtering air. Background technique: [0002] Spray painting is a conventional surface treatment process, which is widely used in the production of products and spare parts. Most of them require a special painting workshop with necessary dust removal facilities to improve the working environment and ensure the quality of finished products. For small-scale spraying equipment, there is no professional dust removal facility at present. The traditional method is to install a fan in front of the spraying operation area, and use the fan to suck away the excess dust and mist generated during the spraying process without any air filtration treatment. Especially during the painting process, a lar...

Problems solved by technology

This system only solves the dust removal for the cleaning treatment of the surface of the workpiece before painting. Even if it can also be used to remove the dust generated during the spraying process, it is also an in-line solution. Although the filter cotton is used to filter the air, the dust accumulated on the filter cotton Dust will still cause secondary pollution
