Description

Technical Field

[0001] This utility model pertains to a type of boiler, specifically a boiler with a dual-color water level display. Background Technology

[0002] In existing technologies, boilers in thermal power plants have very strict requirements for the amount of water inside them during operation. Too much or too little water can lead to accidents. Therefore, the water level inside the boiler must be displayed. Currently, the water level display devices used on boilers are generally in the form of glass tubes. That is, a glass tube with a certain strength is placed vertically on the outside of the boiler. The height of the glass tube is the same as the standard water level height when the boiler is running. The upper end of the glass tube is connected to the boiler steam pipe, and the lower end is connected to the boiler water inlet pipe. In other words, the water level inside the boiler can be seen through the glass tube.

[0003] To prevent scale buildup in boilers, thermal power plants need to periodically add chemicals (phosphates and their solutions, etc.) for scale prevention treatment. This process produces soft sludge such as basic calcium phosphate. While this treatment method can prevent scale buildup, the sludge produced can also negatively impact boiler water level monitoring. The sludge may accumulate inside the glass tube, affecting the water level observation inside the glass tube and thus the accuracy of the water level monitoring. Utility Model Content

[0017] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0018] like Figure 1-2As shown, a boiler with a dual-color water level display includes a body 1. One end of the body 1 has a first pipe 11 and a second pipe 12 communicating with the interior of the body 1, and a dual-color water level display device 2 communicating with the first pipe 11 and the second pipe 12. The dual-color water level display device 2 includes a fixing plate 21 and a glass tube 22 located in the middle of the fixing plate 21. The first pipe 11 and the second pipe 12 are respectively connected to the internal chamber of the body 1, allowing the transport of a cleaning fluid mixture inside the boiler body 1. The cleaning fluid mixture is fed into the glass tube 22 to achieve circulation. The upper and lower ends of the glass tube 22 are respectively connected to the first pipe 11 and the second pipe 12. A coaxially arranged part is provided at the connection point between the end of the first pipe 11 and the upper end of the glass tube 22 for... The pressurization pipe 3 enhances the impact force of the liquid entering the glass tube 22. When the cleaning fluid mixture is sent into the glass tube 22 from the upper end of the first pipe 11, the pressurization pipe 3 can enhance the impact force of the liquid entering the glass tube 22, achieving rapid and powerful flushing of the inside of the glass tube 22 without blind spots, and avoiding water residue in the glass tube 22 that would affect the accuracy of the water level monitoring display. The connection between the end of the second pipe 12 and the lower end of the glass tube 22 is provided with a drain pipe 4 that is coaxial with the glass tube 22 and can be opened and closed. The drain pipe 4 allows the liquid mixture that is rapidly flushed out of the glass tube 22 to be quickly discharged from the drain pipe 4, achieving effective flushing of the glass tube without blind spots, ensuring the cleanliness of the glass tube and the accuracy of the water level monitoring.

[0019] like Figure 2-3 As shown, the lower end of the pressurizing pipe 3 is coaxially connected to and communicates with the glass tube 22. The side wall of the pressurizing pipe 3 is provided with several evenly distributed and downwardly inclined air outlets 31. The side wall of the pressurizing pipe 3 is provided with a ventilation chamber 32 that communicates with each air outlet 31. An air pipe 33 communicating with the ventilation chamber 32 is provided on the outside of the pressurizing pipe 3. An air pump 34 connected to the air pipe 33 is provided at the upper end of the pressurizing pipe 3. The lower end of the pressurizing pipe 3 is coaxially connected to the glass tube 22. When the air pump 34 is started, the gas is delivered to the ventilation chamber 32 through the air pipe 33. Finally, the gas is blown towards the glass tube 22 through the air outlets 31 to form a negative pressure structure, thereby accelerating the liquid flow rate and pressure in the glass tube 22 and enhancing the cleaning and rinsing effect on the glass tube.

[0020] like Figure 2 and 4As shown, the upper end of the drain pipe 4 is coaxially connected to and communicates with the glass tube 22. The second pipe 12 is located radially to the drain pipe 4 and communicates laterally with the drain pipe 4. The drain pipe 4 is equipped with a control pipe 41 that can move up and down to control the opening and closing of the second pipe 12. The outer wall of the control pipe 41 is in contact with the inner wall of the drain pipe 4. The lower end of the glass tube 22 and the second pipe 12 are connected inside the control pipe 41. The lower end of the control pipe 41 is open and communicates with the outside to facilitate sewage discharge. The side wall of the control pipe 41 is provided with a through hole 411 that communicates with the second pipe 12. The lower end of the drain pipe 4 is open and is provided with a sealing device for the control pipe 4. When the control tube 41 moves upward, the through hole 411 on the side wall of the control tube 41 connects with the second pipe 12, the upper end of the control tube 41 connects with the lower end of the glass tube 22, and the lower end of the control tube 41 is sealed by the sealing plug 43, forming a normal water level monitoring state; after the control tube 41 moves downward, the through hole 411 moves downward and is sealed by the side wall of the drain pipe 4, the second pipe 12 is sealed by the side wall of the control tube 41, and the sealing plug 43 separates from the control tube 41, opening the lower end of the control tube 41, so that the liquid mixture generated by rinsing the glass tube 22 can be directly discharged from the drain pipe 4, realizing rapid sewage discharge.

[0021] like Figure 2 and 4As shown, the upper end of the drain pipe 4 is connected to the glass tube 22, and the end is provided with an annular limiting part 42 for limiting the control pipe 41. The annular limiting part 42 limits the upward movement of the control pipe 41 to prevent the control pipe 41 from moving too far upward and affecting the normal connection of the pipeline. The inner wall of the drain pipe 4 is provided with an axially arranged limiting strip 44, and the outer wall of the control pipe 41 is provided with a limiting groove 412 that cooperates with the limiting strip 44. The upper end of the sealing plug 43 can be threaded to the control pipe 41. The cooperation of the limiting strip 44 and the limiting groove 412 is designed to facilitate the movement of the control pipe 41. To prevent the control pipe 41 from deflecting and causing the through hole 411 to misalign with the second pipe 12, thus preventing the second pipe 12 from connecting to the control pipe 41, and to limit the control pipe 41 when the sealing plug 43 is threadedly connected to the control pipe 41, ensuring that the control pipe 41 does not rotate with the sealing plug 43 when it is rotated and tightened, thus preventing the sealing plug 43 from not being able to be smoothly tightened, the lower end of the sealing plug 43 is provided with a limiting block 431 located outside the end of the drain pipe 4, and the connection between the limiting block 431 and the sealing plug 43 is provided with a connecting part 432. 31 limits the sealing plug 43 to ensure a stable seal between the sealing plug 43 and the control pipe 41. An annular inner protrusion 45 is provided at the inner edge of the lower end of the drain pipe 4. The connecting part 432 is threadedly connected to the annular inner protrusion 45. This threaded connection between the connecting part 432 and the annular inner protrusion 45 allows the sealing plug 43 to fix the position of the control pipe 41 when its through hole 411 connects to the second pipe 12 after the control pipe 41 moves upward. This is achieved through the threaded connection between the connecting part 432 and the annular inner protrusion 45, and the threaded connection between the sealing plug 43 and the control pipe 41, preventing the control pipe from being blocked. The movement of pipe 41 causes misalignment between through hole 411 and second pipe 12. Simultaneously, during sewage discharge, sealing plug 43 can be rotated in the opposite direction to separate connecting part 432 from annular inner protrusion 45. Thus, the control pipe 41 can be pulled through the threaded connection between sealing plug 43 and control pipe 41, causing control pipe 41 to move downward and form a seal on second pipe 12. Furthermore, the inner diameter of annular inner protrusion 45 is larger than the outer diameter of sealing plug 43, allowing sealing plug 43 to be unscrewed from control pipe 41, opening the lower end of control pipe 41, and enabling rapid sewage discharge of the rinsing liquid mixture in glass tube 22.

[0022] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
