Description

Technical Field

[0001] The invention relates to a cleaning device in the steel pipe industry, and in particular to a circulation system for cleaning and purifying floating dust on the inner wall of a steel pipe. Background Art

[0002] At present, the whole society is actively advocating the construction of a resource-saving, environmentally friendly and innovative society. Energy conservation and emission reduction have become the main theme of the development of major enterprises. The problem of unorganized dust pollution caused by steel pipe production enterprises during the anti-corrosion operation of the inner and outer walls of steel pipes has attracted social attention.

[0003] During the post-processing of steel pipes, it is necessary to carry out anti-corrosion operations on the inner and outer walls of the steel pipes. In order to make the anti-corrosion materials deeply integrated with the steel pipes and improve the adhesion of the anti-corrosion materials to the surface of the steel pipes, the surface of the steel pipes needs to be cleaned. The outer surface of the steel pipe is exposed to the working environment, so it is convenient to clean this part of the surface, but it is very difficult to clean the inner wall of the pipe. Since the length of the pipeline is generally around 12 meters (or even longer), it is impossible to achieve a thorough and clean cleaning effect by using air cannons for impact, especially the floating dust adhering to the inner wall of the steel pipe is difficult to clean. Therefore, the traditional cleaning method not only consumes a lot of energy, but also has poor cleaning effect, cannot meet the requirements of the anti-corrosion process of the inner wall of the steel pipe, and may affect the quality of the steel pipe. This is an urgent problem to be solved in the field of cleaning the inner wall of the steel pipe today.

[0004] In view of this, researchers in the field of steel pipe corrosion protection are committed to developing new cleaning devices to improve the traditional methods of cleaning the inner wall of steel pipes. Summary of the invention

[0005] The task of the present invention is to provide a circulation system that integrates cleaning and purification of dust on the inner wall of a steel pipe. The wind energy discharged from the dust removal pipe is used to drive the cyclone cleaning system to perform dust removal operations. The dust adhering to the inner wall of the steel pipe can be cleanly and thoroughly removed, and the residual dust on the inner wall of the pipe can be strictly controlled. It plays a positive role in improving the anti-corrosion quality and the emission of unorganized dust, and solves the problems existing in the above-mentioned prior art.

[0010] The purification system is equipped with a filter device and a vibrator. The filter device is provided with filter material. The vibrator is placed above the filter device to vibrate the floating dust in the cylinder after filtering and purification.

[0011] The ash unloading system is arranged below the ash hopper, and is equipped with an ash unloading valve and an ash unloading pipe. The filtered and purified floating dust falls into the ash hopper under the vibration of the vibrator and is discharged externally by the ash unloading system.

[0012] The clean air chamber and the fan are arranged above the purification system. When the fan is started, the purified gas is discharged upward through the pipeline and enters the circulation pipeline for wind energy to drive the working cleaning system for circulation.

[0013] The flocculent material is selected from polyester fiber or wear-resistant fabric.

[0014] The present invention is a circulation system that utilizes wind energy to drive the cleaning work to clean and purify floating dust on the inner wall of a steel pipe.

[0026] See also Figures 3 to 5 The working cleaning system 3 is provided with a frame, a transmission device 4 and a guide device 5, and the transmission device 4 and the guide device 5 are installed on the frame.

[0027] The transmission device 4 is equipped with blades, flocculent material, a shaft with a vortex rod, a bearing assembly and a sector gear conversion assembly. The blades are wind blades with more than three blades, and can be four-blade wind blades, five-blade wind blades, or six-blade wind blades. The specific number of blades can be determined according to the diameter of the inner wall of the steel pipe. The blades are installed on the shaft with a vortex rod, and the blades are provided with a fluid channel. The flocculent material is a flocculent flexible wear-resistant material, and polyester fiber or wear-resistant fabric can be selected. The length of the flocculent material is about 50mm, and the length of the flocculent material can be determined according to needs. The flocculent material is evenly distributed along the circumference of the blade and pressed and fixed.

[0028] The guide device 5 is equipped with a worm wheel, a conversion gear, a power wheel and a support wheel. The turbine is connected to the worm shaft and the conversion gear respectively, the conversion gear is connected to the power wheel, and several support wheels are installed on the frame, wherein the worm on the worm shaft drives the turbine, the turbine drives the forward conversion gear, the conversion gear drives the power wheel forward, and is guided smoothly and moves forward at a constant speed with the support and assistance of several support wheels. The cyclone power working part throws the flocculent flexible wear-resistant material into an arc and flushes the inner wall of the steel pipe 2, which plays a role in powerfully cleaning the floating dust on the inner wall of the steel pipe.

[0029] like Figure 1 and Figure 2 As shown in FIG. 1 , the purification system 6 is equipped with a filter device 8 and a vibrator 9. The filter device 8 is provided with filter material, and the vibrator 9 is arranged above the filter device 8, and the vibrator 9 applies vibration to the floating dust in the cylinder after filtering and purification.
