Description

Technical Field

[0001] The invention relates to the field of tank production, in particular to an inner lining spraying device for tanks. Background Art

[0002] In the chemical, petroleum, food processing and other industries, tanks are key equipment for storing and transporting various liquid or gaseous media. The quality of their internal coating is directly related to the corrosion resistance, service life and safety of the stored substances of the container.

[0003] The Chinese patented method for anti-corrosion of steel tank body with plastic lining, application number 200810060879.3, comprises the following steps: removing the oxide layer and oil layer on the inner surface of the steel tank body; preparing phosphating liquid to phosphate the surface of the steel tank body, washing the steel tank body with clean water and drying it after phosphating; preparing adhesive, and evenly coating the adhesive on the inner surface of the steel tank body; pasting plastic sheets with a thickness of 0.5 to 30 mm on the inner surface of the steel tank body, leaving a seam of 0.1 to 10 cm between different plastic sheets; sealing each interface of the steel tank body with a blind plate, and injecting compressed air into the steel tank body to reach the curing time of the adhesive under the condition of constant pressure of 0.03 to 0.1 MPa; after the adhesive is cured, the gaps between the plastic sheets are filled with welding rods.

[0004] In the Chinese patent application number 202121860117.9, a spraying device for cement lining of cast iron pipes includes a bearing mechanism for bearing and driving the cast iron pipe to rotate. The key is that the spraying device also includes a moving mechanism, a feeding mechanism arranged above the moving mechanism, and a material distribution nozzle, and also includes a hollow shaft motor arranged between the material distribution nozzle and the feeding mechanism and fixedly connected to the feeding mechanism. The inlet end of the material distribution nozzle is connected to the outlet end of the feeding mechanism by means of the hollow shaft of the hollow shaft motor, and the material distribution nozzle has a degree of freedom of rotation by means of the hollow shaft motor. The problem that the cast iron pipe is easy to shake during high-speed rotation in the related technology is solved, so the safety needs to be improved, and the cement lining is easy to delaminate, affecting the product quality.

[0005] However, there are still the following problems in practical applications, specifically:

When the sliding frame 61 moves, the vacuum cleaner 626 is controlled to work, so as to collect the sprayed sand for subsequent spraying work.

[0061] During spraying, the driving motor 53 is controlled to work, thereby driving the corresponding supporting wheel 52 to rotate and rotating the tank. The coating is sprayed onto the inner lining through the spraying tube 632 and the spraying head 633, and the uniform distribution of the coating and the quality of the spraying are ensured by the moving sliding frame 61 and the rotating tank. Under the action of the spring 636, the swing rod 634 swings upward, and the scraping cotton 635 abuts against the inner lining, so as to scrape the inner lining after spraying and evenly distribute the coating. The exhaust fan 640 and the exhaust fan 649 are controlled to work, and the mist generated during spraying is drawn into the collection box 637 through the air inlet 638, and at the same time drawn into the processing box 641 through the connecting pipe 639 and the air inlet pipe 644. At this time, the atomized liquid sprayed out from the spray port is mixed with the mist, thereby condensing the mist into liquid and storing it inside the processing chamber. At the same time, the gas is drawn into the exhaust chamber 643 through the foam breaking net 647 under the action of the exhaust fan 649, and is discharged to the outside through the exhaust port 648 to ensure the health of the operator.

[0062] The first hydraulic rod 7 is controlled to work, and the end of the bottom plate 2 can be swung upward around its hinged end, so as to collect the paint dripping after spraying. The paint is poured into the temporary storage chamber 13 along the bottom of the tank to facilitate subsequent recycling.
