Description

Technical Field

[0001] The utility model relates to a scale prevention and removal device based on the scale prevention and corrosion prevention mechanism of alloy materials, belonging to the technical field of scale removal devices. Background Technique

[0002] During the operation of equipment in industries such as electric power, metallurgy, chemical industry, iron and steel, and paper making, there are serious scaling phenomena. Scaling on the surface of the equipment will increase the thermal resistance, reduce the thermal efficiency of the equipment, increase the maintenance cost, thus causing serious economic losses, and even causing explosions. Scaling in pipelines will increase the flow resistance of pipeline fluids and increase the resistance loss, etc. A series of hazards, so a scale prevention and removal device needs to be set up.

[0003] The Chinese patent discloses a scale prevention device based on a special hole-shaped alloy material chip, with the publication number CN212102976U. The technical solution disclosed in this patent document is as follows: a housing and a number of disc-shaped chips placed inside the housing, and the number of the chips are arranged at intervals; a number of through holes are distributed at intervals on the chips, and the number of the holes constitutes a hole group. The fluid flows into the hole group through an external pipeline, contacts the hole group, and flows out of the hole group; the fluid flows through each of the cores in turn.

[0004] In order to solve the problem of high cost of using chemical agents for scale removal, the prior art is to use a method of designing alloy material chips for scale removal, but there will still be a situation where overpressure protection cannot be provided for the chips. During a period of time when the external device starts or shuts down, it is extremely easy to cause an increase in the medium pressure inside the pipeline. The alloy material chips are relatively thin and have more through holes designed on the side, and the relatively large pressure will impact the alloy material chips, which is extremely easy to cause damage to the alloy material chips.

[0025] The following will make a detailed description of the embodiments of the present utility model with reference to the accompanying drawings. In the following detailed description, for the sake of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present utility model. However, one or more embodiments can also be implemented by those skilled in the art without these specific details.

[0026] As Figures 1 - 5 shown, a scale and corrosion prevention device based on the scale and corrosion prevention mechanism of alloy materials includes an input end flange 1 and an output end flange 11. A overpressure protection mechanism 2 is arranged on the right side of the input end flange 1. The left side of the output end flange 11 is fixedly connected with a scale prevention pipe body 12. The overpressure protection mechanism 2 includes a connecting pipe 21, and the connecting pipe 21 is fixedly connected to the right side of the input end flange 1. The right side of the connecting pipe 21 is fixedly connected to the left side of the scale prevention pipe body 12. A rotating shaft 23 is rotatably connected between the top and bottom of the inner wall of the connecting pipe 21. A connecting sleeve 24 is fixedly sleeved on the outer wall of the rotating shaft 23. A circular flow blocking plate 25 is fixedly installed on the outer wall of the connecting sleeve 24. A stepping motor 22 is fixedly installed on the top of the connecting pipe 21. The output shaft of the stepping motor 22 is fixedly connected to the top of the rotating shaft 23. A pressure sensor 26 is fixedly connected to the top of the connecting pipe 21. The pressure sensor 26 monitors the pressure of the medium inside the connecting pipe 21. After the pressure reaches the first preset value, the stepping motor 22 is controlled to work to drive the rotating shaft 23 to rotate. The circular flow blocking plate 25 is driven to rotate by the transmission of the connecting sleeve 24. The medium inside the connecting pipe 21 is blocked by the circular flow blocking plate 25, so as to reduce the pressure of the medium entering the inner cavity of the scale prevention pipe body 12. The pressure sensor 26 is an existing structural model and can be selected as MPX2200DP, etc. The pressure sensor 26, the solenoid valve 27, and the stepping motor 22 are all electrically connected to an external controller.

[0027] In this embodiment, a solenoid valve 27 is fixedly connected to the top of the receiving pipe 21. The top of the solenoid valve 27 is detachably connected to a shunt pipe 28. The top of the shunt pipe 28 is fixedly connected to a connecting pipe 29. One end of the connecting pipe 29 away from the shunt pipe 28 is fixedly connected to a temporary storage buffer cylinder 291. At the bottom of the inner wall of the temporary storage buffer cylinder 291, an elastic member 292 is fixedly installed. The top of the elastic member 292 is fixedly connected to a sealing slide plate 293. The outer wall of the sealing slide plate 293 is slidably connected to the inner wall of the temporary storage buffer cylinder 291. After the pressure monitored by the pressure sensor 26 reaches the second preset value, the solenoid valve 27 is controlled to open. The medium inside the receiving pipe 21 then enters the temporary storage buffer cylinder 291 through the shunt pipe 28 and the connecting pipe 29. At the same time, the medium will push the sealing slide plate 293 to slide inside the temporary storage buffer cylinder 291 to compress the elastic member 292, realizing the function of relieving pressure and protecting the receiving pipe 21. After the pressure inside the receiving pipe 21 is restored, the initial elastic force of the elastic member 292 drives the sealing slide plate 293 to slide upward, pushing the medium back into the pipeline, avoiding the problem of medium waste.

[0028] In this embodiment, a support member 13 is movably connected to the inner wall of the anti-scaling pipe body 12. A first positioning bolt 14 is threadedly connected to the inner wall of the support member 13. The threaded end of the first positioning bolt 14 is movably connected to the inner wall of the anti-scaling pipe body 12. A cross bar 15 is fixedly installed on the left side of the support member 13. A rubber ring 17 is movably connected to the inner wall of the anti-scaling pipe body 12. An alloy material chip 16 is fixedly connected to the inner wall of the rubber ring 17. A cross groove 162 is formed at the center of the side of the alloy material chip 16. The inner wall of the cross groove 162 is movably connected to the outer wall of the cross bar 15. A through hole 161 is formed on the side of the alloy material chip 16. A protruding block 163 is fixedly installed on the right side of the alloy material chip 16. A second positioning bolt 164 is threadedly connected to the top of the protruding block 163. The threaded end of the second positioning bolt 164 extends to the bottom of the protruding block 163 and is movably connected to the top of the cross bar 15. Loosen the first positioning bolt 14, and the state where the support member 13 is fixed to the inner wall of the anti-scaling pipe body 12 can be released. Then, the support member 13 and the cross bar 15 can be withdrawn from the inner cavity of the anti-scaling pipe body 12. Loosen the second positioning bolt 164, and the fixed state of the alloy material chip 16 on the outer wall of the cross bar 15 can be released. Then, the alloy material chip 16 can be disassembled and replaced on the cross bar 15. On the contrary, the alloy material chip 16 and the cross bar 15 can be reinstalled in the inner cavity of the anti-scaling pipe body 12, facilitating the maintenance work. The alloy material chip 16 is an existing alloy structure. The alloy material chip 16 is melted from a variety of metals with different electronegativities in a certain ratio. After contacting the fluid, it can change the local fluid electrostatic potential, generate a polarization phenomenon, change the local PH value, making it difficult for the cations and anions in the fluid to combine into scale. At the same time, the alloy material chip 16 can also gradually dissolve and fall off the formed scale block.

[0029] The working principle of the scale prevention and removal device based on the scale prevention and corrosion prevention mechanism of alloy materials of the present utility model is as follows: When in use, this structure is connected to the pipeline from the input end flange 1 and the output end flange 11. The medium will flow through the inner cavity of the through hole 161 and make full contact with the alloy material chip 16. The alloy material chip 16 can change the local fluid static potential, making it difficult for the cations and anions in the fluid to combine into scale. The pressure sensor 26 monitors the pressure of the medium inside the receiving pipe 21. After the pressure reaches the first preset value, the control stepper motor 22 works to drive the rotation of the rotating shaft 23, and then drives the rotation of the circular flow blocking plate 25. The circular flow blocking plate 25 performs a flow blocking process on the medium inside the receiving pipe 21, reducing the pressure of the medium entering the inner cavity of the scale prevention pipe body 12, and realizing the function of protecting the alloy material chip 16 from impact.

[0030] In this article, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
