Embodiment Construction

[0014] Such as figure 1 with figure 2 As shown, a powder internal repair machine includes a spray gun 1, a powder storage tank 2, a powder pump 3, and a spray head group 4. The muzzle of the spray gun 1 is connected to the air inlet of the powder pump 3 through a through joint 5. The powder storage tank 2 The powder outlet pipe 6 is connected with the powder inlet of the powder pump 3, the spray gun 1 is connected with an air source through a hose 7, and the powder outlet of the powder pump 3 is connected with the nozzle assembly 4 through a telescopic tube 8.

[0015] The spray gun 1 and the hose 7 are connected by a quick connector 9. The telescopic tube 8 is provided with a support seat 10, and the spray head group 4 is composed of three horn-shaped spray heads, and the gas source is 0.4-0.6 MPa.

[0016] The invention is mainly suitable for the internal repair operation of the weld seam during the anti-corrosion construction of small-caliber steel pipes. The specific internal ...

Abstract

The invention discloses a powder interior repairing machine which comprises a spray gun, a powder storage tank, a powder pump and a nozzle assembly, wherein the muzzle of the spray gun is communicated with a gas inlet of the powder pump through a straight joint, the powder storage tank is communicated with a powder inlet of the powder pump through a powder outlet pipe, the spray gun is connected with a gas source through a flexible pipe, and a powder outlet of the powder pump is connected with the nozzle assembly through a telescoping tube. The powder interior repairing machine provided by the invention has a simple structure and is convenient to use; with the design of the telescoping tube, the powder interior repairing machine can realize repairing at different crator positions in a steel pipe through adjusting the length of the telescoping tube; and because the nozzle assembly is designed to be composed of three trumpet-shaped nozzles, the jet area of powder is great, the speed of repairing is fast, effective and complete repairing of any crator position at the inner wall of the steel pipe can be realized, and safety in use of an integral pipeline is guaranteed.

Description

Technical field [0001] The invention relates to a steel pipe internal repair device, in particular to a powder internal repair machine. Background technique [0002] Generally, the conveying pipe is connected by several steel pipes with a length of less than 12 meters. When the steel pipes are connected by welding, the inner wall coating of the plastic-coated steel pipes will be damaged by high temperature, posing safety hazards and requiring timely repair. This equipment specializes in repairing the plastic coating on the inner wall of the pipe weld, which is easy to operate and ensures the safety of the overall pipeline. Summary of the invention [0003] The purpose of the present invention is to provide a powder internal repairing machine, which solves the problem of repairing the plastic coating on the inner wall of the weld joint when the pipeline is connected, thereby ensuring the safety of the entire pipeline. [0004] In order to achieve the above objectives, the technical...
