Description

Technical Field

[0001] This utility model relates to the field of pipe wall coating technology, and in particular to a pipe wall coating machine. Background Technology

[0002] A pipeline is a device used to transport gases, liquids, or fluids containing solid particles. Some pipelines are often used to transport corrosive media, therefore, corrosion resistance is one of the important quality standards for crossbeam pipelines. In order to extend the service life of the pipeline, a protective film is sprayed on the inner wall of the pipeline, which plays a good protective role. However, it is quite difficult to coat the inner wall of some existing pipelines, and there is no existing device for coating thin pipes. Therefore, we designed a simple device for coating thin pipes. Utility Model Content

[0003] To overcome the technical defects of the existing technology, this utility model provides a pipe wall coating machine, which has the characteristics of simple structure and easy operation. During the traction process, the nozzles facing the inner wall of the pipe will evenly spray the coating material onto the inner wall of the pipe.

[0004] The technical solution adopted by this utility model is: a pipe wall coating machine, including a paint supply device and a moving block that moves along the inner wall of the pipe. The moving block is equipped with a spray pipe, and the front end of the spray pipe is equipped with multiple connecting pipes facing the periphery of the pipe. Each connecting pipe is equipped with a nozzle. The moving block is equipped with a ring at the front end of the spray pipe, and the ring is hooked with a first traction rope that pulls the moving block forward along the pipe. The liquid outlet of the paint supply device is connected to the end of the spray pipe via a liquid supply pipe. The end of the moving block is equipped with a second traction rope that pulls the moving block backward along the pipe.

[0005] Preferably, the movable block is adapted to the inner diameter of the pipe.

[0006] Preferably, the second traction rope pulls the moving block backward along the pipe at a constant speed.

[0007] Preferably, there are 4-6 spray nozzles, which are evenly distributed around the periphery of the spray pipe.

[0008] Preferably, guide portions are provided at both ends of the movable block.

[0009] Preferably, a sponge cleaning block is fixed to the front end of the movable block, and the surface of the sponge cleaning block is in close contact with the inner wall of the pipe.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model features a movable block that moves along the inner wall of a pipe. A spray pipe is mounted on the movable block, and nozzles facing the inner wall of the pipe are mounted on the spray pipe. First, a first traction rope is passed through the pipe. Then, the movable block is pulled forward along the pipe to the other end. The first traction rope is then removed, and the paint supply equipment is turned on for spraying. A second traction rope pulls the movable block backward along the pipe. During this pulling process, the nozzles facing the inner wall of the pipe evenly spray the coating onto the inner wall of the pipe. This design is simple in structure and easy to operate.

[0012] 2. The front end of the movable block of this utility model is fixed with a sponge cleaning block. The surface of the sponge cleaning block is in close contact with the inner wall of the pipe. In this way, when the movable block moves forward, it cleans the inner wall of the pipe, so that the spray coating is combined with the inner wall of the pipe. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0019] like Figures 1-3As shown, this embodiment provides a pipe wall coating machine, including a paint supply device 1 and a moving block 3 that moves along the inner wall of a pipe 2. The moving block is provided with a spray pipe 4, and the front end of the spray pipe 4 is provided with multiple connecting pipes 5 facing the periphery of the pipe 2. Each connecting pipe 5 is equipped with a nozzle 6. The moving block 3 is provided with a ring 7 at the front end of the spray pipe 4, and the ring 7 is hooked with a first traction rope 8 that pulls the moving block 3 forward along the pipe. The liquid outlet of the paint supply device 1 is connected to the end of the spray pipe 4 via a liquid supply pipe 9. The end of the moving block 3 is provided with a second traction rope 10 that pulls the moving block 3 backward along the pipe 2. By setting a movable block 3 that moves along the inner wall of pipe 2, a spray pipe 4 is provided on the movable block 3, and a nozzle 6 facing the inner wall of pipe 2 is provided on the spray pipe 4. First, the first traction rope 8 is passed through the inside of pipe 2, and then the movable block 3 is pulled forward along pipe 2 to the other end of pipe 2. Then the first traction rope 8 is removed, and then the paint supply equipment 1 is turned on for spraying. The movable block 3 is pulled backward along pipe 2 by the second traction rope 10. During the pulling process, the nozzles 6 facing the inner wall of pipe 2 evenly spray the coating onto the inner wall of pipe 2. It has the characteristics of simple structure and easy operation.

[0020] The movable block 3 is adapted to the inner diameter of the pipe, which provides a good limiting effect on the movable block and prevents it from shaking too much.

[0021] The second traction rope 10 pulls the moving block 3 backward along the pipe 2 at a constant speed. The second traction rope 10 can be pulled by a machine or manually, as long as the speed is constant.

[0022] The spray nozzles 6 are provided in 4-6 units and are evenly distributed around the periphery of the spray pipe 4, so that there are no dead corners in the spraying and the spraying layer can be evenly sprayed onto the inner wall of the pipe.

[0023] The movable block 3 is provided with guide parts 11 at both ends, which facilitates installation and cleaning.

[0024] The front end of the movable block 3 is fixed with a sponge cleaning block 12. The surface of the sponge cleaning block 12 is in close contact with the inner wall of the pipe 2. In this way, when the movable block 3 moves forward, it cleans the inner wall of the pipe 2, so that the spray coating is bonded to the inner wall of the pipe 2. The sponge cleaning block 12 is fixed by bolts and needs to be replaced after each cleaning to avoid secondary pollution.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0026] Working principle: A moving block 3 is set up to move along the inner wall of the pipe 2. A spray pipe 4 is set on the moving block 3, and a nozzle 6 facing the inner wall of the pipe 2 is set on the spray pipe 4. First, the first traction rope 8 is passed through the pipe 2. Then, the moving block 3 is pulled forward along the pipe 2 to the other end of the pipe 2. Then, the first traction rope 8 is removed. Then, the paint supply equipment 1 is turned on to spray. The moving block 3 is pulled backward along the pipe 2 by the second traction rope 10. During the pulling process, the nozzles 6 facing the inner wall of the pipe 2 evenly spray the coating onto the inner wall of the pipe 2. It has the characteristics of simple structure and easy operation.

[0027] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
