Fluorescent spraying device for U-shaped electric heating tube of electric heater

Abstract

The invention discloses a fluorescent spraying device for a U-shaped electric heating tube of an electric heater. The fluorescent spraying device comprises a bottom plate, wherein a stirring tank is arranged on the bottom plate; a storage barrel is arranged in the stirring tank; an inner barrel body is arranged in the storage barrel; the surface of the inner barrel body is of a microporous structure; a first drive motor is arranged on the stirring tank; the first drive motor is connected with a drive shaft; a stirring blade is arranged at the lower end of the drive shaft; the stirring blade is arranged in the inner barrel body; a temperature control plate is arranged on the inner bottom of the storage barrel; the temperature control plate is distributed on the outer bottom of the inner barrel body; a temperature controller is arranged on the inner bottom of the stirring tank; a grinding pipeline is arranged on the top of the stirring tank; a feeding hole is formed in the top of the stirring tank; a spraying chamber is formed in the bottom plate. According to the fluorescent spraying device disclosed by the invention, the storage barrel and the inner barrel body are integrally heated, so that fluorescent powder and glue solution mixed liquor are stirred in a constant-temperature environment, and a fluorescent coating effect can be realized on the surface of the U-shaped electric heating tube of the electric heater.

Description

technical field [0001] The invention relates to a fluorescent spraying device, in particular to a fluorescent spraying device for a U-shaped electric heating tube of an electric heater. Background technique [0002] Spraying is a coating method in which spray guns or disc atomizers are dispersed into uniform and fine droplets by means of pressure or centrifugal force and applied to the surface of the object to be coated. It can be divided into air spraying, airless spraying, electrostatic spraying and various derived methods of the above basic spraying forms, such as large flow and low pressure atomization spraying, thermal spraying, automatic spraying, multi-group spraying, etc. The spraying operation has high production efficiency and is suitable for manual operation and industrial automation production. It is widely used in hardware, plastics, furniture, military industry, ships and other fields. It is the most commonly used coating method today; spraying operations req...
