During the working process of the evaporator, liquid level control is a key factor in ensuring evaporation efficiency and preventing equipment damage. Therefore, we need a liquid level control device.

[0004] However, in the above-mentioned comparative documents, the boiling of the liquid inside the evaporator will generate bubbles, liquid flow and vibration, all of which may affect the stability of the float. In particular, when the boiling is more intense, the float may be subjected to a greater impact force, causing its position to shift or shake, thereby causing the position of the sensor set above the float and the external sensor to be unable to be accurately aligned as the liquid boils, thereby causing inaccurate detection data;

[0005] In order to solve the above problems, a liquid level control device is proposed in the present application. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-3 A liquid level control device includes a pipeline body 1, the inner side wall of the pipeline body 1 is fixedly connected to a limit rod 2, the outer side wall of the limit rod 2 is penetrated with a slide groove 3, the limit rod 2 is slidably connected with a slide rod 4 through the slide groove 3, two slide rods 4 are provided, the two slide rods 4 are distributed in a linear array, the outer side walls of the two slide rods 4 are adapted to the inner side wall of the slide groove 3, the outer side walls of the two slide rods 4 are fixedly connected with a float 5, the float 5 is spherical, and a cavity 6 is opened inside the float 5 to facilitate improving the buoyancy of the float 5, so as to facilitate more accurate detection of the height of the liquid, the outer side wall of the float 5 is opened with a slot 7, the float 5 is fixedly inserted with a sensor 8 through the slot 7, the outer side wall of the pipeline body 1 is fixedly penetrated with a sensor 9, the position of the sensor 9 corresponds to the position of the sensor 8, in When in use, since the cavity 6 is provided inside the float 5, the float 5 can float on the liquid surface. As the liquid level changes, the float 5 will slide up and down along the direction of the chute 3 along the change of the liquid level. When the sensor 9 senses that the sensing body 8 is gradually moving away from the sensor 9, a signal is emitted to add liquid to the pipeline body 1 to avoid dry burning due to too little liquid inside the pipeline body 1. When the float 5 floats up to the position corresponding to the sensor 9 following the liquid level, the sensor 9 senses the sensing body 8, thereby stopping the addition of liquid to avoid excessive liquid. Since the position of the limit rod 2 is fixed and the float 5 slides inside the chute 3 through the slide rod 4, the position of the float 5 is limited by the chute 3, thereby avoiding the horizontal position of the float 5 changing during the up and down movement, thereby avoiding inaccurate liquid level detection.

[0024] Reference Figure 4The outer walls of the two sliding rods 4 are rotatably connected with connecting rings 10, and the outer walls of the two connecting rings 10 are fixedly connected with scrapers 11. The outer walls of the two scrapers 11 are adapted to the inner walls of the limiting rod 2. When the float 5 moves up and down following the liquid level, the connecting rings 10 and the scrapers 11 will be driven to move synchronously. Since the outer walls of the two scrapers 11 are adapted to the inner walls of the limiting rod 2, the two connecting rings 10 and the scrapers 11 will clean the inner walls of the limiting rod 2 during the movement, thereby avoiding the float 5 from getting stuck during the movement.

[0025] Reference Figure 4 A fixing groove 12 is provided at the bottom of the limiting rod 2, and a connecting port 13 is provided at the bottom of the limiting rod 2. The opening diameter of the connecting port 13 is the same as the inner wall diameter of the limiting rod 2. When in use, the impurities cleaned inside the limiting rod 2 will be discharged along the connecting port 13.

[0026] Reference Figure 4 The limit rod 2 is provided with a connecting block 14 through the fixing groove 12, and the outer wall of the connecting block 14 is provided with a mounting groove 15, and the interior of the mounting groove 15 is provided with a mounting hole. The connecting block 14 is slidably connected with a fixing block 16 through the mounting groove 15, and a spring is installed on the side of the fixing block 16 close to the mounting groove 15, and the fixing block 16 is located inside the mounting groove 15, and the outer wall of the fixing block 16 is adapted to the inner wall of the mounting groove 15. When in use, the staff can insert the connecting block 14 into the fixing groove 12. During the insertion process, the outer wall of the fixing block 16 is squeezed, thereby squeezing the spring. When the fixing block 16 is retracted into the interior of the mounting groove 15, it can be inserted. When it is fully inserted, due to the gradual expansion of the space, the fixing block 16 pops out of the interior of the mounting groove 15, thereby fixing the connecting block 14.

[0027] Reference Figure 4 The bottom of the connecting block 14 is fixedly connected to a storage box 18, and the top of the storage box 18 is fixedly connected to a connecting tube 17. The outer wall of the connecting tube 17 is adapted to the inner wall of the limiting rod 2. When in use, the connecting tube 17 is inserted into the interior of the limiting rod 2 along the connecting port 13 to collect impurities inside the limiting rod 2.

[0028] Reference Figure 1 The top of the pipeline body 1 is fixedly connected with a liquid inlet pipe 19, which is convenient for the staff to add liquid to the inside of the pipeline body 1 to avoid scaling caused by dry burning inside the pipeline body 1.

[0029] Working principle: When in use, since the cavity 6 is provided inside the float 5, the float 5 can float on the liquid surface. As the liquid level changes, the float 5 will slide up and down along the direction of the chute 3 along the change of the liquid level. When the sensor 9 senses that the sensing body 8 is gradually moving away from the sensor 9, a signal is emitted to add liquid to the pipeline body 1 to avoid dry burning due to too little liquid inside the pipeline body 1. When the float 5 floats up to the position corresponding to the sensor 9 following the liquid level, the sensor 9 senses the sensing body 8, thereby stopping the addition of liquid to avoid excessive liquid. Since the position of the limit rod 2 is fixed and the float 5 slides inside the chute 3 through the slide rod 4, the position of the float 5 is limited by the chute 3, thereby avoiding the horizontal position of the float 5 changing during the up and down movement, thereby avoiding inaccurate liquid level detection.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
