Spray coating machine having conveying pipe storing function and used for treating methanal

Abstract

The invention relates to a spray coating machine having a conveying pipe storing function and used for treating methanal. The spray coating machine comprises a main body, a conveying pipe and a spraying gun and further comprises a contracting and releasing mechanism and a cleaning mechanism. The contracting and releasing mechanism comprises a rotating connector, a drum, a drive pipe, a drawing pipe, a power pump, a screw rod, a sliding rod, a moving block, a second gear, a third gear, two first bearings, two second bearings and two supports. The cleaning mechanism comprises two clamping blocks, two elastic ropes, two cleaning brushes and four connecting assemblies. A drive assembly comprises a motor and a first gear. Each connecting assembly comprises a cylindrical notch, a connecting column and a spring. According to the spray coating machine having the conveying pipe storing function and used for treating methanal, by means of the contracting and releasing mechanism, winding and storing of a conveying pipe can be achieved, use convenience of the spray coating machine is improved, by means of the cleaning mechanism, the conveying pipe is cleaned, abrasion speed of the conveying pipe is reduced, and practicality of the spray coating machine is improved.

Description

technical field [0001] The invention relates to the field of formaldehyde treatment equipment, in particular to a spraying machine for formaldehyde treatment with a storage function of a feeding pipe. Background technique [0002] Formaldehyde is a colorless and irritating gas, also known as formaldehyde. Colorless, irritating to human eyes and nose. Soluble in water and ethanol. Reducing, especially in alkaline solution, the reducing ability is stronger. Can burn, vapor and air form explosive mixture. It can be produced by the dehydrogenation or oxidation of methanol under the catalysis of silver, copper and other metals, and it can also be separated from the oxidation products of hydrocarbons. It can be used as raw materials for phenolic resin, urea-formaldehyde resin, vinylon, urotropine, pentaerythritol, dyes, pesticides and disinfectants.

AI Technical Summary

Problems solved by technology

[0003] In the process of domestic formaldehyde treatment, it is usually necessary to use a sprayer to spray biological enzymes. The sprayer in the prior art is usually equipped with a long pipeline. However, the pipeline does not have an effective storage device, which reduces the convenience of the sprayer. Not only In this way, when the spraying machine in the prior art is in use, the pipes tend to drop to the ground, causing dust and debris to accumulate on the pipes, causing wear and corrosion of the pipes, and shortening the service life of the pipes
