Dropped bottom intermediate air knife double-turning plate quick color changing spraying room

Abstract

The invention discloses a dropped bottom intermediate air knife double-turning plate quick color changing spraying room. The spraying room comprises a spraying room body and a dust clearing device which is arranged on the bottom of the spraying room body, wherein the dust clearing device comprises a bottom plate with an inverse V-shaped cross section, an air knife which is arranged on the top of the bottom plate and a recycling cavity for recycling dust, a plurality of air holes are formed in the side wall of the air knife and are connected with an air source, gaps are left between the bottom ends of the bottom plate and the side wall of the spraying room body, an inlet of the recycling cavity is communicated with the gaps, and an outlet of the recycling cavity is communicated with an air pipe. The bottom plate with the inverse V-shaped cross section is adopted, the dust falls onto the bottom plate and then slides towards the gaps under the action of self gravity, and in the meanwhile, air holes in the side wall of the air knife blow air outside to accelerate the dust to slide towards the gaps. Consequently, after the spraying room with the structure is adopted, the dust removing efficiency is higher, the air source with high air pressure does not need to be configured, and the spraying room is simple in structure and is low in cost.

Description

technical field [0001] The invention relates to a rapid color-changing spray booth with air knife double flaps in a convex bottom. Background technique [0002] The spray booth is the place where the workpiece is sprayed. The workpiece will generate a lot of dust during the spraying process. Therefore, the spray booth needs to be equipped with a device for removing and recovering dust. The device is generally installed at the bottom of the spray booth. In the existing dust removal and recovery devices, the bottom of the spray booth is generally set in a flat structure, and then air knives are set in the middle or at both ends to blow the dust on the bottom surface to the entrance of the dust collection device; the removal and recovery of such structures Because the dust device adopts a flat bottom surface, it is not conducive to the movement of dust towards the inlet of the dust collection device, and its dust removal and recovery efficiency is low, and the air knife needs t...

Problems solved by technology

In the existing dust removal and recovery devices, the bottom of the spray booth is generally set in a flat structure, and then air knives are set in the middle or at both ends to blow the dust on the bottom surface to the entrance of the dust collection device; the removal and recovery of such structures Because the dust device adopts a flat bottom surface, it is not conducive to the movement of dust towards the inlet of the dust collection device, and its dust removal and recovery efficiency is low, and the air knife needs to be equipped with a high-pressure air source, and dust will often accumulate on the bottom surface. Therefore, It is necessary to provide a spray booth with higher dust removal efficiency
