[0033] Embodiment:

[0034] Such as Figures 1 to 4As shown in the figure, an automatic liquid level control system in an alkali condensate water tank of the present utility model includes an alkali condensate water tank 1, a magnetic flap level gauge 2, and a liquid discharge booster pump 3. The magnetic flap level gauge 2 is communicated with the inner cavity of the alkali condensate water tank 1, and the liquid level height in the magnetic flap level gauge 2 is the same as the liquid level height in the alkali condensate water tank 1. The liquid discharge booster pump 3 is communicated with the inner cavity of the alkali condensate water tank 1, and the liquid discharge booster pump 3 is used to discharge the liquid in the alkali condensate water tank 1. The magnetic flap level gauge 2 is electrically connected to the liquid discharge booster pump 3, and the magnetic flap level gauge 2 controls the start or stop of the liquid discharge booster pump 3. In this embodiment, the magnetic flap level gauge 2 is used to monitor the liquid level height in the alkali condensate water tank 1 in real time, and the start or stop of the liquid discharge booster pump 3 is controlled by the monitoring structure of the magnetic flap level gauge 2. When the liquid level height in the alkali condensate water tank 1 is too low, the liquid discharge booster pump 3 is shut down, and the cooled roasted alkali steam is continuously introduced into the alkali condensate water tank 1. When the liquid level height in the alkali condensate water tank 1 is too high, the liquid discharge booster pump 3 is started, and the rapid discharge effect of the alkali condensate liquid is achieved through the liquid discharge booster pump 3. Specifically, the magnetic flap level gauge 2 includes a liquid level cavity 21, the liquid level cavity 21 is fixed on the side wall of the alkali condensate water tank 1, an upper liquid level switch 22 and a lower liquid level switch 23 are arranged in the liquid level cavity 21, and both the upper liquid level switch 22 and the lower liquid level switch 23 are electrically connected to the liquid discharge booster pump 3. When the upper liquid level switch 22 is triggered, the liquid discharge booster pump 3 starts. When the lower liquid level switch 23 is triggered, the liquid discharge booster pump 3 stops.

[0035] In this embodiment, in combination with the structural characteristics of the magnetic flap level gauge 2, both the upper liquid level switch 22 and the lower liquid level switch 23 are magnetic switches, and a magnetic float 24 is arranged in the liquid level cavity 21. The magnetic float 24 floats up and down with the liquid level in the liquid level cavity 21. The specific switch triggering situation is as follows. When the magnetic float 24 rises to the upper liquid level switch 22, the upper liquid level switch 22 is in a triggered state. When the magnetic float 24 drops to the lower liquid level switch 23, the lower liquid level switch 23 is in a triggered state.

[0036] The magnetic flap level gauge 2 further includes an indicating magnetic flap 25 and a magnetic flap cavity 26. The magnetic flap cavity 26 is fixed on the side wall of the liquid level cavity 21, and a plurality of indicating magnetic flaps 25 are rotatably arranged in the magnetic flap cavity 26. During the rising process of the magnetic float 24, the indicating magnetic flap 25 is driven to flip to the front side. During the descending process of the magnetic float 24, the indicating magnetic flap 25 is driven to flip to the back side. In this embodiment, the magnetic flap cavity 26 can isolate the indicating magnetic flap 25 from the liquid, thereby avoiding the influence of the liquid on the flipping of the indicating magnetic flap 25, so that the situation where it cannot flip normally does not occur, and different colors are applied to the front and back sides of the indicating magnetic flap 25, so as to more conveniently understand the liquid level height in the alkali condensate water tank 1.

[0037] The magnetic flap level gauge 2 further includes an upper connecting pipe 27 and a lower connecting pipe 28. One end of the upper connecting pipe 27 is communicated with the vacuum space at the top of the alkali condensate tank 1, and one end of the lower connecting pipe 28 is communicated with the alkali condensate at the bottom of the alkali condensate tank 1. The other end of the upper connecting pipe 27 is communicated with the top of the liquid level chamber 21, and the other end of the lower connecting pipe 28 is communicated with the bottom of the liquid level chamber 21. In this embodiment, the upper connecting pipe 27 and the lower connecting pipe 28 can effectively realize the connection between the alkali condensate tank 1 and the liquid level chamber 21, and a structure similar to a communicating vessel is formed between the alkali condensate tank 1 and the liquid level chamber 21, so as to ensure that the liquid level height in the liquid level chamber 1 is the same as the liquid level height in the alkali condensate tank 1.

[0038] The magnetic flap level gauge 2 further includes an alkali-resistant and waterproof cover 29 made of polyurethane material, and the upper liquid level switch 22 and the lower liquid level switch 23 are both covered with a layer of the alkali-resistant and waterproof cover 29. In this embodiment, the alkali-resistant and waterproof cover 29 can effectively protect the upper liquid level switch 22 and the lower liquid level switch 23 from being corroded by alkali liquid and damaged, ensuring that they can normally transmit control signals to the driver of the liquid discharge booster pump 3, and further controlling the working state of the liquid discharge booster pump 3.

[0039] It should be noted that a liquid discharge port 11 is provided at the bottom of the alkali condensate tank 1, and the liquid discharge port 11 is communicated with the water inlet of the liquid discharge booster pump 3. A vacuum discharge port 12 is provided at the top of the alkali condensate tank 1, and the vacuum discharge port 12 is communicated with the air inlet of the vacuum pump 4. A liquid inlet 13 is further provided on the side wall of the tank body of the alkali condensate tank 1, and the liquid inlet 13 is communicated with the liquid outlet of the cooler 5.

[0040] It should be noted that the circuit connection structure and the control program between the magnetic flap level gauge 2 and the liquid discharge booster pump 3 in this embodiment are all conventional technical means, so they will not be elaborated here.

[0041] The specific embodiments described above further elaborate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
