Description

Multi-pipe simultaneous descaling and dusting operation system

The invention relates to the technical field of metal surface technology processing auxiliary equipment, in particular to a multi-pipe simultaneous descaling powder spraying operation system. Background technique

Pipes such as steel pipes and cast iron pipes are widely used in China's petroleum, chemical, water supply and drainage, power stations, paper, leather, ventilation and extraction corrosive gas smoke, but steel pipes and cast iron pipes are good conductors for electricity. During storage and use, local battery reactions may occur due to chemical and electrochemical effects. The surface is highly rusty and tends to contaminate the transport medium. Therefore, it is often necessary to carry out special rust and rust removal treatment on the surface.

With the increasing awareness of environmental protection in China and the gradual improvement of relevant laws and regulations, the environmental protection requirements for various types of projects are getting higher and higher, and many construction methods and equipment that seriously pollute the environment will be gradually replaced or eliminated. Pre-corrosion cleaning of the outer surface of large tanks is a technology that needs improvement. All along, the surface of the large tank outer wall before the anti-corrosion cleaning, the use of open sandblasting and rust removal operations. Although this method can meet the requirements of surface cleaning quality, since the sand material is not recycled after being sprayed onto the surface of the tank, the consumption of sand on site is large, resulting in a large waste of raw materials, and more seriously, in the sandblasting process. In the middle of the scene, the dust is pervasive, the environmental pollution is very serious, and the operators work at high altitude under such harsh conditions, which poses a great threat to life safety and physical health. It also affected the normal construction of other work types around.

At present, there are mainly two kinds of steel pipe conveying methods and devices in the rust removal treatment of steel pipes and steel bars. One is that the motor drives the parallel lumps and wheels at the same time and rotates in the same direction through the chain and the transmission rod, thereby driving the steel pipe toward The transmission mode of the front linear movement; the second is the simultaneous rotation of the motor through the cardan shaft or by two radial parallel, rubber wheels with appropriate distances and axially intersecting rubber wheels. The transmission method that drives the steel pipe to move straight forward.

The main disadvantage of the two types of conveyors currently in common use is that only one steel pipe can be delivered at a time. Therefore, the efficiency of the work of conveying the steel pipe is low, and the cost in the production process is increased to some extent; in addition, the adjustable range of the angle of the rubber wheel is small, and the adjustment work is cumbersome, time-consuming, and cannot be conveniently and quickly. Adjust the speed of the steel pipe by adjusting the angle of the rubber wheel.

In addition, the applicant's name is "Transport and Derusting Device for Multiple Steel Pipes" on December 13, 2006, and the Chinese invention patent of Application No. 200610165832.4, the publication number is CN1962197, and the publication date is 2007. On the 16th of the month, it describes a transmission and descaling device for a plurality of steel pipe reinforcements and a transmission method for a plurality of pipes. By providing a driving wheel and providing a driven wheel on both sides of the upper portion of the driving wheel, the driving wheel can be On the top, a plurality of pipes are placed between the two driven wheels, and the synchronous transmission of the plurality of pipes is realized by the friction between the driving wheel and the pipe and the pipe and the pipe.

The above technical solution satisfactorily solves the shortcoming that the previous pipeline transmission method can only transmit one steel pipe at a time, and the work efficiency is low, but when the pipeline is subjected to rust removal or dusting operation, due to the relationship between the plurality of steel pipes There is contact with each other, entering the descaling process of the descaling equipment or entering the dusting process of the dusting equipment. The rust removal effect or dusting of the contact area is sometimes not ideal, and secondary rust removal or dusting is required to achieve the desired effect.

The self-operating machine is moved by the control of the left and right motor speeds. In addition, there is a gas supply system, which connects the air compressor to the powder spray tank through a pipeline to supply high pressure gas to deliver the spray material to the spray gun.

The advantages of the present invention over the prior art:

1. Real multi-tube transfer through the transfer manifold.

2. The small wheel on the separation frame is used to reduce the resistance and realize the multi-tube simultaneous operation, which greatly improves the work efficiency. A small wheel on the support fork, a small wheel is arranged on the support forks on both sides, and a plurality of small wheels are arranged on the inner support fork, and the small wheel can move up and down relative to the support fork through the small wheel moving hole.

3. Improvement of the dusting bin. In the past, the spray guns in the powder spray bin were a cluster. As long as the single pipe is used, it can now be transported by multiple pipes. Therefore, the spray gun is arranged around the circumference of the dusting bin to make the dusting more uniform. . In the present invention, the frequency heating machine is also used to preheat the pipeline to increase the adhesion of the powder during dusting.
