Description
The present invention relates to a pipe coating apparatus, and more particularly, to an annular pipe coating apparatus capable of uniformly and rapidly resin coating inner and outer surfaces of a pipe.
In general, piping is installed in various plant facilities or in industrial facilities to be used for powder or fluid transportation, and is widely used as a component of a machine or a structure.
If the pipe is used for a certain period of time, corrosion will occur and rust will be generated, and the pipe will be narrowed due to the rust nodule, so that the flow rate will be reduced.
There is a problem in that when the corrosive fluid is transported through the pipe, corrosion is generated in the pipe and the service life of the pipe is shortened.
In addition, the corroded scale is solidified as time elapses, and acts as a cause of obstructing the inside of the pipe, thereby causing another problem that the flow of the fluid is inhibited.
Therefore, in order to use such a pipe as an industrial material, it needs to be processed so as to have a certain diameter and length and to be coated to improve durability or corrosion resistance.
Therefore, in the case of piping for transporting corrosion-inducing fluids, an anti-corrosive material for preventing corrosion is coated or paint is applied to the inner diameter. Depending on the use of the piping, the piping itself may be made of a zinc- Tube.
However, in the case of the piping coated with the anticorrosive material, a homogeneous coating can not be obtained, and since the coating thickness is thin and the adhesive force is weak, there is a problem that it is easily peeled off.
In the case of paint coating, since the surface is not smooth and rough, recently synthetic resin is coated by mechanical device, but in most cases, it is often a device which can mainly coat only the outer diameter of the pipe.
Therefore, coating of the inside diameter of the pipe is not easy, so that the inside of the pipe is easily corroded to shorten the life span, and the corroded debris causes the pipe to be clogged, which hinders the flow of the fluid.
It is an object of the present invention to provide an annular pipe coating apparatus capable of uniformly and quickly resin-coating inner and outer surfaces of a pipe to improve the satisfaction of resin-coated pipe products. The purpose is to provide.
In order to accomplish the object of the present invention, an annular pipe line coating apparatus is provided in an annular pipe line coating apparatus, which is formed in an annular shape bending along a circumferential direction of the pipe line in a pipe line to be coated, An air fuel supply member communicating with one side of the body and supplying air and fuel to the inside of the body, and a plurality of air injection nozzles An inner surface coating part composed of a raw material compressed air supplying member for supplying a raw material and compressed air into the inside of the body so as to spray the raw material; And a support portion for supporting the inner surface coating portion.
Here, the inner surface of the conduit can be coated while being reciprocally rotated at a predetermined angle along the circumferential direction of the conduit.
Further, a separate heating unit for preheating the channel may be provided on the front and rear of the inner surface coating unit along the moving direction of the inner surface coating unit.
In addition, a temperature sensor for measuring the surface temperature of the channel in real time may be provided on one side of the channel.
The support portion is fixed to the inner side of the inner surface coating portion and extends along the longitudinal direction of the pipe, and is disposed along the circumferential direction of the inner surface coating portion. The support portion is fixed to one side of the extension bar, And a plurality of support bars rotatably installed at an end of the support bar in contact with the inner surface of the channel.
The support bars may be installed at the front and rear of the inner surface coating portion with respect to the inner surface coating portion, respectively.
The outer surface of the channel overlaps the inner surface coating portion so that the outer surface of the channel can be coated simultaneously with the inner surface. The outer surface of the channel is formed in an annular shape bent along the circumferential direction of the channel, An air fuel supply member communicating with one side of the body and supplying air and fuel to the inside of the body, and a plurality of air injection nozzles An outer surface coating part composed of a raw material compressed air supplying member for supplying a raw material and compressed air into the inside of the body so as to spray the raw material; And a supporting portion for supporting the outer surface coating portion may be provided.
The support portion may include a plurality of extension bars fixed to the outer side of the outer surface coating portion and extending along the longitudinal direction of the pipe and disposed along the circumferential direction of the inner surface coating portion, And a plurality of support bars rotatably installed at an end of the support bar in contact with the outer surface of the channel.
