Electrodusting chamber bottom cleaning device and method for cleaning static powder by applying same

Abstract

The invention relates to an electrodusting chamber bottom cleaning device which comprises a negative pressure exhaust pipe arranged at the bottom of a dusting chamber, wherein the top end of the exhaust pipe is provided with a plurality of powder guiding devices, the top ends of the powder guiding devices are ridge tops or sharp tops, two sides of the powder guiding devices are provided with guide inclines, a gap used for exhausting powder is arranged between bottoms of adjacent guide inclines of every two adjacent power guiding devices, and the powder guiding devices guide the power to slide to the gaps along the guide inclines to enter the exhaust pipe, thus the powder accumulation is reduced, and the power exhausting effect is good. The electrodusting chamber bottom cleaning device provided by the invention has the advantages of simple and more compact structure, low manufacture cost and easiness in cleaning.

Description

technical field [0001] The invention relates to a device for cleaning the bottom of an electrostatic powder spraying chamber and a method for cleaning electrostatic powder using the device. Background technique [0002] like figure 1 As shown, the traditional electrostatic powder spraying room is generally composed of an upper top wall 011, a side wall 012 and a lower bottom wall 013. The bottom wall 013 is provided with an exhaust pipe device for absorbing powder. The exhaust pipe 02 of the suction port 021, the top surface of the exhaust pipe 02 is a plane, and the port of the exhaust pipe 02 is equipped with an exhaust fan (not shown in the figure). When the workpiece enters the powder spraying room, use the spray gun to spray the electrostatic powder to the workpiece , and the electrostatic powder that has not been sprayed on the workpiece will fall down due to its own weight, and under the action of the negative pressure of the draft, this part of the electrostatic pow...

AI Technical Summary

Problems solved by technology

This structure has the following disadvantages: the top surface of the exhaust pipe is flat, and powder will accumulate on the top and both sides of it, and the effect of powder extraction is poor, which brings relatively large troubles to cleaning

Generally, this kind of spray booth needs to be equipped with cleaning devices on both sides of the exhaust pipe, but the structure is complicated, the manufacturing cost is high, the structure is not compact, the cleaning is time-consuming and laborious, and the cleaning effect is not good.
