A spraying device based on solar vacuum tube heat-absorbing coating

Abstract

The invention discloses a spraying device based on a heat-absorbing coating of a solar vacuum tube, which comprises a main body, the main body is provided with a gluing chamber with an opening forward, and a first placement is fixed on the bottom wall of the gluing chamber. Seat, the top surface of the first placement seat can place a vacuum tube, the first placement seat can slightly clamp the vacuum tube, and the upper side of the vacuum tube is provided with a clamping block that can press against the inner wall of the vacuum tube, so There are two groups of clamping blocks symmetrically arranged on the left and right. The invention can make the spraying process of the heat-absorbing coating on the outer periphery of the solar vacuum tube more convenient and easy. Just place the vacuum tube in the device, and the device can directly and automatically run the one-step forming spraying process. And the spraying effect is more uniform and perfect, and the whole inventive device makes the spraying process more green and environmentally friendly, ensuring the personal safety of operators.

Description

technical field [0001] The invention relates to the technical field of spraying, in particular to a spraying device based on a heat-absorbing coating of a solar vacuum tube. Background technique [0002] At present, solar water heaters are still widely used, and vacuum tube solar water heaters occupy the vast majority of the market. Solar vacuum tubes include inner glass tubes and outer glass tubes. The outer surface of the inner glass tubes needs to be sprayed with a heat absorbing coating to increase the heat absorption effect. However, the existing spraying process and spraying effect are very unsatisfactory. Manual operation is usually used, which is time-consuming and labor-intensive, and each operator's spraying technique and spraying state are different, which seriously affects the spraying effect, which will directly affect the solar vacuum tube. The heat-absorbing effect reduces the product quality. In addition, the environment of the operation workshop that usually...

[0002] At present, solar water heaters are still widely used, and vacuum tube solar water heaters occupy the vast majority of the market. Solar vacuum tubes include inner glass tubes and outer glass tubes. The outer surface of the inner glass tubes needs to be sprayed with a heat absorbing coating to increase the heat absorption effect. However, the existing spraying process and spraying effect are very unsatisfactory. Manual operation is usually used, which is time-consuming and labor-intensive, and each operator's spraying technique and spraying state are different, which seriously affects the spraying effect, which will directly affect the solar vacuum tube. The heat-absorbing effect reduces the quality of the product. In addition, the environment of the operation workshop where this kind of manual spraying is usually used is very poor and not environmentally friendly, which greatly affects the personal safety of the operators.
