Problems solved by technology

[0002] In the construction of construction projects, the work of sandblasting and rust removal of steel components is relatively heavy, and dry sand is required for sandblasting. The current dry sand dehumidification method is still the original method of spreading and drying, which takes a long time and is low in efficiency. labor intensive
At the same time, it is easy to cause dust to fly during sandblasting and rust removal, which seriously pollutes the environment.

Embodiment Construction

[0018] The wet sand delivery device includes a conveyor belt 17 .

[0019] like figure 2 As shown, the conveyor belt 17 is provided with a sand spreading grate 18, which spreads the wet sand to facilitate subsequent drying.

[0020] The wet sand drying device includes a drying hopper 19, the upper opening of the drying hopper 19 is used as the wet sand inlet 2, and one side of the upper opening is located below the discharge end of the conveyor belt 17, and is connected to the conveyor belt 17. A fan 20 is provided on the other side of the opening of the upper end opposite to the discharge end of the belt 17 . The below of the delivery end of the conveyor belt is provided with a sand baffle 28, and the wet sand falling from the delivery end of the conveyor belt 17 is blown and dehumidified under the action of the blower fan, and the sand baffle prevents the sand particles from being blown out of the drying bucket by the wind.

[0021] The bottom of the drying hopper 19 is p...

Abstract

The present invention discloses a sand blasting rust removal apparatus, which comprises: a wet sand conveying device, a wet sand drying device, a dry sand tank, a sand blasting head, an air compressor, an air heating tank, and a hot air nozzle. During sand blasting rust removal operation, dry sand enters the dry sand tank, air is conveying into the air heating tank through the air compressor to be heat to form high pressure hot air, the dry sand is directly blasted on a steel workpiece under a high pressure hot air effect to carry out rust removal operation, a surface effect of the rust-removed steel workpiece is good, an anticorrosion standard of paints is achieved, the hot air nozzle can directly blow the high pressure hot air to the steel workpiece so as to produce a good rust removal effect and reduce a use amount of the sand, and rust removal can be performed only by using the high pressure hot air without the dry sand if the rust of the workpiece is less. In addition, the surface of the rust-removed workpiece is heated, paint adhesion is strong, and an anticorrosion effect is strong.

Description

technical field [0001] The invention relates to the field of derusting equipment, in particular to a sandblasting and derusting device. Background technique [0002] In the construction of construction projects, the work of sandblasting and rust removal of steel components is relatively heavy, and dry sand is required for sandblasting. The current method of dry sand dehumidification is still the original method of spreading and drying, which takes a long time and is low in efficiency. Labor intensity is high. At the same time, it is easy to cause dust to fly during sandblasting and rust removal, which seriously pollutes the environment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sandblasting and derusting device with good effect of sandblasting and derusting, which can effectively reduce environmental pollution and labor intensity. [0004] In order to solve the above-mentioned technical problems, the te...
