Description

Technical Field

[0001] This utility model relates to the field of boiler dosing technology, and in particular to an electrode-type electric boiler dosing and mixing device. Background Technology

[0002] In the operation of large power plants, boilers, as the core heat energy conversion equipment, directly affect the power generation capacity and economic benefits of the entire power plant through their operating efficiency and safety. With prolonged use, various minerals and impurities, such as calcium and magnesium hardness ions, gradually accumulate in the boiler water. Under high temperature and pressure conditions, these components easily form scale, which deposits on the boiler's heating surfaces. This not only reduces the boiler's heat transfer efficiency and increases energy consumption but can also lead to serious accidents such as overheating, deformation, or even tube rupture. Simultaneously, dissolved oxygen, carbon dioxide, and inappropriate pH values ​​in the boiler water accelerate the corrosion of the boiler's metal components, further shortening its service life and increasing maintenance costs.

[0003] To address the aforementioned issues, power plants commonly employ in-boiler water treatment technology. This involves adding specific chemical agents, such as phosphates, hydrazine, and sodium hydroxide, to the boiler water to control its quality and prevent scaling and corrosion. These agents react with hardness ions in the water to form insoluble precipitates, which are then discharged outside the boiler via the blowdown system. Alternatively, they can inhibit corrosion by adjusting the pH and redox properties of the boiler water. Currently, liquid and powdered chemicals are commonly used. However, if powdered chemicals are directly added to the boiler, their dissolution rate is slow, resulting in a slower onset of action. Therefore, this issue needs to be addressed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an electrode-type electric boiler chemical mixing device. When using this device, the addition of powdered chemicals can be pre-mixed to facilitate rapid onset of action after subsequent application.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electrode-type electric boiler dosing and mixing device includes a base plate, two connecting plates symmetrically fixedly connected to the upper end of the base plate, and a housing fixedly connected to the upper ends of the two connecting plates; an agitation mechanism, including a drive motor installed at the lower end of the housing, the output shaft of the drive motor extending into the housing and fixedly connected to a first rotating tube, multiple exhaust pipes fixedly connected to the bottom side wall of the first rotating tube, all of the exhaust pipes communicating with the first rotating tube, the other ends of the exhaust pipes being sealed, and multiple exhaust holes being opened at the inner top of each exhaust pipe; a gas supply mechanism, which cooperates with the agitation mechanism; and an auxiliary mechanism for improving the agitation effect.

[0007] Preferably, the inner top of the shell is provided with a feeding port, and the inner bottom of the shell is provided with a drain pipe.

[0008] Preferably, a sealing cap is installed at the feeding port, and a manual valve is installed at the drain pipe.

[0009] Preferably, the air supply mechanism includes an air pump installed on the upper end of the housing, the air pump's outlet end extending into the housing and communicating with the upper end of the first rotating tube via a rotary joint.

[0010] Preferably, the auxiliary mechanism includes a second rotating tube disposed outside the first rotating tube, a plurality of stirring rods being fixedly connected to the outside of the second rotating tube, a guide groove being disposed inside the second rotating tube, and a guide strip cooperating with the guide groove being disposed outside the first rotating tube.

[0011] Preferably, a connecting plate is provided inside the housing, the second rotating tube passes through the connecting plate and is rotatably connected to the connecting plate via a bearing, and an electric telescopic rod is fixedly connected to the inner top of the housing, the telescopic end of the electric telescopic rod being fixedly connected to the upper end of the connecting plate.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By starting the air pump to inject gas, the gas enters multiple exhaust pipes through the first rotating pipe and is discharged from the exhaust port. This process not only promotes the flow of water, but also the shear force generated when the bubbles rise and burst effectively enhances the mixing effect. At the same time, the rotation of the first rotating pipe drives the rotation of the exhaust pipe, ensuring that the bubbles are evenly distributed and further improving the uniformity of mixing.

[0014] 2. In addition to the gas rising to promote mixing, a first rotating tube driven by a drive motor is designed to rotate, and a second rotating tube and its stirring rod are rotated and reciprocated up and down through the cooperation of a guide sleeve and a guide groove. This compound motion mode greatly enhances the mixing effect and ensures that the reagent and water are fully mixed in a short time.

[0015] 3. After mixing, high-pressure gas is injected using an air pump, and the mixed liquid is forced into the boiler through the drain pipe, achieving efficient and stable injection operation. By dissolving before injection, the onset speed of the agent is effectively improved. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-3 An electrode-type electric boiler dosing and mixing device includes a base plate 2, two connecting plates 3 are symmetrically fixedly connected to the upper end of the base plate 2, and a shell 1 is fixedly connected to the upper end of the two connecting plates 3. A feeding port 6 is provided at the top inner part of the shell 1, and a drain pipe 4 is provided at the bottom inner part of the shell 1. The other end of the drain pipe 4 is connected to the inside of the boiler. A sealing cover is installed at the feeding port 6, and a manual valve is installed at the drain pipe 4.

[0022] The device also includes a stirring mechanism, which includes a drive motor 14 installed at the lower end of the housing 1. The output shaft of the drive motor 14 extends into the housing 1 and is fixedly connected to a first rotating tube 8 (a rotating sealing gasket is installed at the point where the drive motor 14 passes through the housing 1). Multiple exhaust pipes 12 are fixedly connected to the side wall of the bottom part of the first rotating tube 8. All the exhaust pipes 12 are connected to the first rotating tube 8. The other end of the multiple exhaust pipes 12 is sealed. Multiple exhaust holes 13 are opened in the inner top of each exhaust pipe 12.

[0023] It also includes an air supply mechanism, which works in conjunction with the stirring mechanism. The air supply mechanism includes an air pump 5 installed on the upper end of the housing 1. The air outlet of the air pump 5 extends into the interior of the housing 1 and is connected to the upper end of the first rotating pipe 8 through a rotary joint 9. The use of the rotary joint 9 ensures the sealing of the rotating connection. The air pump 5 here is a plunger type air pump. The plunger type air pump has a high pressure output capacity and is suitable for use in high-pressure applications.

[0024] The system also includes an auxiliary mechanism to improve the stirring effect. The auxiliary mechanism includes a second rotating tube 10 located outside the first rotating tube 8. Multiple stirring rods 11 are fixedly connected to the outside of the second rotating tube 10. A guide groove 17 is provided on the inside of the second rotating tube 10. A guide strip 16 that cooperates with the guide groove 17 is provided on the outside of the first rotating tube 8. A connecting plate 15 is provided inside the housing 1. The second rotating tube 10 passes through the connecting plate 15 and is rotatably connected to the connecting plate 15 through a bearing. The bearing connection provides good support and ensures rotatable connection. An electric telescopic rod 7 is fixedly connected to the top inside the housing 1. The telescopic end of the electric telescopic rod 7 is fixedly connected to the upper end of the connecting plate 15.

[0025] In this invention, when in use, the sealing cover is opened, the manual valve is closed, and an appropriate amount of medicine and water are added from the feeding port 6. Then, the air pump 5 and the drive motor 14 are started. After the air pump 5 is started, the injected gas will enter multiple exhaust pipes 12 through the first rotating pipe 8 and finally be discharged from multiple exhaust holes 13. The rising of the gas will promote the flow of water and achieve the purpose of mixing. In addition, some bubbles rise and break in the water, and the shear force generated can also play a good mixing role. The start of the drive motor 14 will drive the first rotating pipe 8 to rotate, and the rotation of the first rotating pipe 8 will drive the multiple exhaust pipes 12 to rotate, so that the bubbles rise evenly and the mixing uniformity is improved.

[0026] In addition, the rotation of the first rotating tube 8 will also cause the second rotating tube 10 to rotate through the cooperation of the guide bar 16 and the guide groove 17, and finally cause multiple stirring rods 11 to rotate, further improving the mixing effect. During this process, the electric telescopic rod 7 can be activated to extend and retract back and forth, and the connecting plate 15 can be used to make the second rotating tube 10 move up and down back and forth, which, together with its rotation, further improves the mixing effect.

[0027] After mixing is complete, the sealing cap is installed, the manual valve is opened, and the air pump 5 is started. With the injection of high-pressure gas, the liquid inside the shell 1 can be forced into the boiler through the drain pipe 4 to realize the injection operation.
