[0027] See also Figure 1-4 The utility model provides a technical solution: a boiler drum liquid level balance container, including a drum body 1, a drain pipe 2 is fixed through the lower end of the drum body 1, the lower end outer wall of the drain pipe 2 is fixedly connected with an end cover 3, a sewage pipe 4 is installed through the surface of the end cover 3 below the drainage pipe 2, a filtering mechanism 5 is provided on the upper end outer wall of the sewage pipe 4, and a sealing cylinder 6 is movably connected to the inner wall of the end cover 3.

[0028] The drum body 1 on the side of the drain pipe 2 is connected to the monitoring mechanism 10 through a negative pressure sampling tube 7. A positive pressure sampling tube 8 is installed on the monitoring mechanism 10 on the side of the negative pressure sampling tube 7. A balancing cup 9 is provided at the upper end of the positive pressure sampling tube 8.

[0029] A return pipe 12 is installed through the drum body 1 on the side of the balancing cup 9, and the outer wall of the end of the return pipe 12 is fixedly connected to the condensation tank 11. A water inlet pipe 13 is installed through the side of the upper end of the condensation tank 11, and a sealing rubber sleeve 14 is fixedly connected to the inner wall of the upper end of the condensation tank 11. A knob 15 is movably installed on the inner wall of the condensation tank 11 inside the sealing rubber sleeve 14, and a pressure plate 16 is movably provided on the lower end of the knob 15.

[0030] In this example, the end cover 3 and the sealing cylinder 6 are threadedly connected, the positive pressure sampling tube 8 and the steam drum body 1 are set through, and the condensation tank 11 and the steam drum body 1 are fixedly connected, which makes it convenient for the user to rotate the sealing cylinder 6 to disassemble and assemble the sealing cylinder 6, and improve the stability of the positive pressure sampling tube 8 and the condensation tank 11.

[0031] The filtering mechanism 5 in this example includes a positioning cylinder 501 and a filter screen 502. The positioning cylinder 501 is sleeved on the outer wall of the sewage pipe 4, and the inner wall of the positioning cylinder 501 is fixedly connected with the filter screen 502, which facilitates the filtering of the sewage discharged from the steam drum through the filtering mechanism 5, thereby facilitating subsequent treatment of the sewage.

[0032] In this example, the positioning tube 501 and the sewage pipe 4 are threadedly arranged, and the positioning tube 501 and the end cover 3 are fitted together, so that the user can rotate the positioning tube 501 to disassemble and assemble the positioning tube 501 .

[0033] The knob 15 in this example is threadedly connected to the condensation tank 11 , and the knob 15 and the pressure plate 16 form a rotating structure, which makes it easy for the user to rotate the knob 15 so that the knob 15 moves numerically relative to the condensation tank 11 , thereby driving the pressure plate 16 to move.

[0034] In this example, the pressure plate 16 and the return pipe 12 are both fitted with the sealing rubber sleeve 14. The front view shape of the return pipe 12 is set to an "L" shape, which facilitates the movement of the pressure plate 16 to cause the sealing rubber sleeve 14 to deform and fit the return pipe 12, thereby fully sealing the condensation tank 11.

[0035] Working principle: According to Figure 1-4 As shown, the user puts the positioning cylinder 501 on the drain pipe 4 and tightens the positioning cylinder 501 so that the positioning cylinder 501 fits the end cover 3, thereby completing the installation of the filter screen 502, and then the user inserts the sealing cylinder 6 into the end cover 3 and tightens the sealing cylinder 6, thereby completing the installation of the sealing cylinder 6. Then, when the drum body 1 is working, the steam in the drum body 1 enters the condensation tank 11 through the return pipe 12, and the steam condenses into water in the condensation tank 11. Then the condensed water gradually accumulates and covers the return pipe 12. Next, the condensed water flows into the balance cup 9 through the return pipe 12, so that the positive pressure sampling tube 8 uses the condensed water. At this time, the monitoring mechanism 10 monitors the pressure difference between the negative pressure sampling tube 7 and the positive pressure sampling tube 8. When the drum body 1 needs to be repaired, the user rotates the knob 15, and then the knob 15 moves downward relative to the condensation tank 11, and then The knob 15 drives the pressure plate 16 to move downward, and then the pressure plate 16 drives the sealing rubber sleeve 14 to deform, and as the pressure plate 16 continues to move, the pressure plate 16 finally drives the sealing rubber sleeve 14 to fit the return pipe 12, thereby completing the full sealing of the return pipe 12. At this time, the condensation tank 11 is sealed, thereby preventing the evaporation of condensed water. Therefore, the effect of the device in preventing the reduction of condensed water is enhanced, which improves the practicality of the device. Then the water inlet pipe 13 is used to replenish water to the condensation tank 11. When the boiler body 1 needs to discharge the internal sewage, the user opens the valve provided on the drain pipe 2, and then the sewage in the boiler body 1 flows into the sealing cylinder 6 through the drain pipe 2. Next, the sewage in the sealing cylinder 6 is discharged from the device through the sewage pipe 4. At this time, the filter screen 502 filters the sewage discharged from the sewage pipe 4, thereby facilitating subsequent treatment of the sewage.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
