Anode cylinder inner wall spraying device and control method

Abstract

The invention relates to the technical field of spraying equipment, in particular to an anode cylinder inner wall spraying device and a control method. The device is composed of a hollow sleeve, a foldable three-layer telescopic supporting leg, a slidable rotary spraying gun main body, an electric movable pulley, a controller and a remote controller, wherein the foldable three-layer telescopic supporting leg is arranged on the hollow sleeve; the slidable rotary spraying gun main body is divided into three layers from inside to outside, wherein the inner layer is a sliding layer, and the spraying gun main body is controlled to move upwards and downwards in the direction of the hollow sleeve through the electric movable pulley device; the middle layer is an electric turntable and drives a high-pressure storage tank of the outer layer to rotate, a plurality of atomizing nozzles are arranged on the outer wall of the high-pressure storage tank, an infrared distance measuring probe is installed on the outer wall, and a remote and automatic control mode is adopted. According to the special spraying device for the hollow cylinder, the coating can be sprayed on the inner wall of the cylinder rapidly, conveniently and uniformly, the good protection can be achieved for the device which is installed a workpiece similar to a cathode pin at the center of the cylinder; and the device is suitable for internal spraying work of various hollow cylindrical workpieces.

Description

technical field [0001] The invention relates to the technical field of spraying equipment, in particular to a spraying device and a control method for the inner wall of an anode cylinder. Background technique [0002] The spraying of the inner wall of the cylinder has always been a problem, especially when it is necessary to go to the application site for spraying, it is extremely complicated to disassemble the workpiece and spray the inner wall of the cylinder, and it is difficult to achieve uniform coating on the inner wall of the cylinder regardless of whether it is disassembled or not. The walls are even difficult to paint. The anode cylinder is a common cylinder, which is widely used in various fields of waste gas treatment. The electrostatic adsorption electric field formed together with the cathode needle is an important means of waste gas treatment. The oily fumes and water drops will adhere to the inner wall of the anode cylinder, which is difficult to clean. For t...

Problems solved by technology

[0005] The existing anode tube spraying equipment is suitable for factory spraying. If the anode tube has been installed on the project site, it is very difficult to spray the hydrophobic and oleophobic coating, especially the cathode needle is installed in the center of the anode tube, which makes the inner wall of the anode tube more difficult. Spraying is difficult, and there are many applications where the workpiece is installed in the center of the anode cylinder, so a device that can spray the installed anode cylinder is developed
