Description

Technical Field

[0001] The utility model relates to the technical field of thick-film electronic stainless steel tubes, in particular to a corrosion-resistant thick-film electronic stainless steel tube. Background Art

[0002] Thick film electronic stainless steel pipes can be used as electrical heating elements and can be used to transport and heat fluids. When thick film electronic stainless steel pipes are used for a long time, scale often adheres to their inner wall. This is because when the fluid flows in the pipe, the temperature rises or falls, which may cause the solubility of certain substances to change, thereby causing the precipitation of scale. Or the fluid contains a large amount of dissolved salts, hard water components and other soluble solids. When these dissolved substances are concentrated to a certain extent, they will precipitate to form scale.

[0003] The presence of scale can easily form local electrochemical imbalance on the inner wall of thick film electronic stainless steel pipes, causing corrosion. In severe cases, it can also damage the pipe structure and reduce its life. Workers often need to regularly dismantle thick film electronic stainless steel pipes to clean scale, which results in long downtime and troublesome operation. To this end, we propose a corrosion-resistant thick film electronic stainless steel pipe. Utility Model Content

[0019] See also Figure 1 and Figure 2 In the figure, the rotating assembly includes a rotating disk 3, which is fixedly connected to the top of the rotating rod 8, and a rotating column 2 is fixedly connected to the upper edge of the rotating disk 3; specifically, hold the rotating rod 8 and rotate it, the rotating rod 8 can drive the rotating disk 3 to rotate, and the rotating disk 3 can drive the rotating rod 8 to rotate, thereby facilitating the rotation of the rotating rod 8.

[0020] See also Figure 2 In the figure, the outer wall of the rotating column 2 is provided with a plurality of anti-skid grooves 10, and the plurality of anti-skid grooves 10 are arranged in a circular array around the center of the rotating column 2; specifically, by providing the anti-skid grooves 10, an anti-skid effect can be achieved when the rotating column 2 is rotated.

[0021] See also Figure 3 and Figure 4 In the figure, the reset assembly includes a connecting ring 6, which is fixedly sleeved on the outer wall of the rotating rod 8. A spring 14 is fixedly connected between the lower end of the connecting ring 6 and the outer wall of the conical block 11, and the spring 14 is slidably sleeved on the outer wall of the rotating rod 8.

[0022] See also Figure 2 In the figure, each group of blades 9 has three blades, and the three blades 9 are arranged in a linear array from top to bottom; specifically, the multiple blades 9 are evenly and orderly distributed, so as to have a better stirring effect on the descaling agent and the fluid.

[0023] See also Figure 3 In the figure, the conical block 11 is made of rubber material; specifically, the conical block 11 made of rubber material has good sealing performance.

[0024] Working principle: When it is necessary to clean the scale attached to the inner wall of the tube body 5, first, the outlet end of the injection pump is connected to the connecting tube 4 through a pipeline, and the inlet end of the injection pump can be connected to the descaling agent storage container through a pipeline, and then the descaling agent can be injected into the injection tube 1 by starting the injection pump. The injection pump is a well-known prior art and will not be described in detail.

[0025] Then, the rotating rod 8 can be rotated through the rotating assembly, and the rotating rod 8 can drive the conical block 11, the connecting disk 12, the connecting ring 6, the spring 14, the connecting column 15 and the two sets of blades 9 to rotate together. When the connecting column 15 rotates to contact the inclined surface of the arc block 13 under the blocking ring 7, as the connecting column 15 continues to rotate, the connecting column 15 will rotate and move downward along the inclined surface of the arc block 13, then the conical block 11 and the connecting disk 12 can rotate and move downward, and the conical block 11 can stretch the spring 14 connected to the connecting ring 6 until the connecting column 15 leaves the arc block 13. Under the action of the spring 14, the conical block 11 and the connecting disk 12 will automatically move up and reset.

[0026] It should be noted that when the conical block 11 moves downward and leaves the blocking ring 7, the descaling agent will fall into the fluid in the tube body 5 along the gap between the blocking ring 7 and the conical block 11, and when the conical block 11 moves upward, it will block the blocking ring 7, thereby preventing the descaling agent from continuing to fall into the fluid in the tube body 5. With the rotation of the rotating rod 8, the descaling agent can be intermittently released in the fluid in the tube body 5. The intermittent release of the descaling agent can more evenly integrate the descaling agent into the fluid in the tube body 5, and with the rotation of the two sets of blades 9, the descaling agent and the fluid in the tube body 5 can be more fully mixed together, so that the contact effect between the descaling agent and the scale attached to the inner wall of the tube body 5 is better, and the effect of cleaning the scale is better. Then, the fluid in the tube body 5 can be discharged and replaced.
