[0002] In the field of industrial smoke and dust removal, water film dust collectors are widely used due to their high dust removal efficiency. As the core component of water film dust collectors, the water level of the water tank directly affects the dust removal effect and the safe operation of the equipment. The water level sensor is a key component for real-time monitoring of the water level in the water tank. However, in practical applications, the reliability of the water level sensor faces many challenges.

[0003] In traditional water film dust collectors, the liquid level sensor is often installed in an exposed position. However, the circulating water in the tank inevitably carries particulate impurities, which easily adhere to the surface of the liquid level sensor. This can cause the sensor's sensing element to be covered, leading to problems such as monitoring data deviation, abnormal signal transmission, or even malfunction. This affects the normal use of the liquid level sensor. Traditional cleaning methods mostly involve disassembly, which is cumbersome and makes it difficult to automate the cleaning of the liquid level sensor, thus affecting the cleaning efficiency.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a water film dust collector water tank level early warning device, including a water film dust collector 1, a water tank 2, and a water pump 3. A second connecting pipe 5 is fixedly connected to one side of the water film dust collector 1. The end of the second connecting pipe 5 away from the water film dust collector 1 is fixedly connected to the outlet of the water pump 3. A first connecting pipe 4 is fixedly connected to the inlet of the water pump 3. The end of the first connecting pipe 4 away from the water pump 3 is fixedly connected to one end of the water tank 2. An inspection door 17 is provided on the outer surface of the water tank 2. A water inlet pipe 6 is fixedly installed on the top of the water tank 2. A liquid level sensor 11 is fixedly installed inside the water tank 2. A cleaning component is provided on the outer surface of the liquid level sensor 11. The cleaning component includes a fixing ring 12. A cleaning ring 13 is slidably installed on the inner wall of the fixing ring 12. The inner wall of the cleaning ring 13 is in the shape of a soft brush. The inner wall of the cleaning ring 13 slides in contact with the outer surface of the liquid level sensor 11. A fixing groove 14 is opened on one side of the cleaning ring 13.

[0025] Furthermore, a threaded hole 15 is provided on one side of the fixing ring 12, and a locking bolt 16 is threadedly connected inside the threaded hole 15. One end of the locking bolt 16 contacts the inside of the fixing groove 14.

[0026] Furthermore, the water storage tank 2 is internally rotatably connected to a threaded rod 8, and a limiting plate 9 is threadedly sleeved on the outer surface of the threaded rod 8. The limiting plate 9 is L-shaped, and one side of the limiting plate 9 is fixedly connected to one side of the fixing ring 12.

[0027] Furthermore, a limiting groove 10 is provided on the inner wall of the water storage tank 2, and the inner wall of the limiting groove 10 is slidably connected to the end of the limiting plate 9 away from the fixing ring 12.

[0028] Furthermore, a drive motor 7 is fixedly installed at the top of the water storage tank 2. The output end of the drive motor 7 rotates through the interior of the water storage tank 2 and is fixedly connected to the top of the threaded rod 8.

[0029] Furthermore, when the water film dust collector 1 is working, the water pump 3 draws water from the water storage tank 2 through the first connecting pipe 4 and delivers it to the water film dust collector 1 through the second connecting pipe 5 to form a circulating water path for dust removal. The liquid level sensor 11, which is fixedly installed inside the water storage tank 2, monitors the water level in the tank in real time. When the water level changes, the liquid level sensor 11 converts the liquid level information into an electrical signal and transmits it to the external control system. If the water level is lower than the preset minimum liquid level threshold or higher than the maximum liquid level threshold, the control system triggers the external early warning device to issue an audible and visual alarm, reminding the staff to deal with it in time and avoid the water level abnormality affecting the dust removal effect of the water film dust collector 1 or causing equipment failure.

[0030] Furthermore, as the water in the storage tank 2 is recycled, impurities in the water may adhere to the surface of the level sensor 11, affecting its monitoring accuracy. At this time, the cleaning assembly can be activated, followed by the start of the drive motor 7. Its output end drives the threaded rod 8 to rotate inside the storage tank 2. Since the limiting plate 9 is threadedly sleeved on the outer surface of the threaded rod 8, and one end of the limiting plate 9 is fixedly connected to the fixing ring 12, while the other end slides in the limiting groove 10, the rotation of the threaded rod 8 will cause the limiting plate 9 to move axially along the threaded rod 8, thereby driving the fixing ring 12 and the cleaning ring 13 to move up and down. Then, during the movement of the cleaning ring 13, the soft brush inside the cleaning ring 13 will contact the outer surface of the level sensor 11. The cleaning ring 13 then automatically cleans the impurities attached to its surface, thereby ensuring the normal operation of the level sensor.

[0031] Furthermore, when the cleaning ring 13 needs to be replaced, open the inspection door 17, then turn the locking bolt 16 to disengage it from the inside of the fixing groove 14, and then the cleaning ring 13 can be released from the fixing. Then slide the cleaning ring 13 downward so that it slides out at the bottom of the liquid level sensor 11, so that the cleaning ring 13 can be easily replaced.

[0032] Structural Description:

[0033] Water film dust collector 1: The core device of the entire smoke and dust removal system. Working in conjunction with water pump 3, water storage tank 2 and connecting pipes, it uses circulating water to form a water film to adsorb and filter dust particles in the flue gas, thereby achieving industrial flue gas purification. It is a key device for achieving dust removal goals.

[0034] Water storage tank 2: Serves as the "water source" for the operation of the water film dust collector 1, storing recycled water to provide a continuous and stable water supply for the entire water circulation system. An integrated liquid level sensor 11 is used to monitor the water level in real time, and the matching cleaning components ensure the normal operation of the sensor. The inspection door 17 on the outer surface facilitates equipment maintenance and replacement of the cleaning ring 13.

[0035] Water pump 3: The power heart of the water circulation system. It draws water from the water storage tank 2 and transports it to the water film dust collector 1 through the first connecting pipe 4 and the second connecting pipe 5 to maintain water circulation and provide power support for the dust removal function of the water film dust collector, ensuring that the dust removal process is uninterrupted.

[0036] First connecting pipe 4: connects the inlet of water pump 3 to water storage tank 2. It is a dedicated channel for water from the water storage tank to flow into the water pump, ensuring water flow at the beginning of the water circulation and providing a stable path for the water pump to pump water.

[0037] The second connecting pipe 5 connects the outlet of the water pump 3 to the water film dust collector 1, accurately delivering the water pumped by the water pump to the water film dust collector, allowing the water to participate in the dust removal process. It is the key transmission link for completing water circulation and realizing the dust removal function.

[0038] Water inlet pipe 6: Installed at the top of water storage tank 2, it acts as a "water replenishment channel". When the water level in the storage tank drops due to circulation, water can be replenished in time through this pipe to ensure the stability of the water level in the storage tank and thus maintain the continuous operation of the water film dust collector.

[0039] Drive motor 7: The power source for the cleaning component, installed at the top of the water tank 2. It drives the threaded rod 8 to rotate through the output end, converting the rotational power into the linear motion of the cleaning component, driving the limit plate 9, the fixing ring 12 and the cleaning ring 13 to move, thereby realizing the automated cleaning of impurities on the surface of the liquid level sensor 11.

[0040] Threaded rod 8: Rotatably connected inside the water storage tank 2 and linked with the drive motor 7. Utilizing the threaded transmission principle, it converts the rotational motion of the drive motor into the linear motion of the limit plate 9, precisely controlling the up and down movement distance and position of the cleaning components to ensure accurate and effective cleaning work.

[0041] Limiting plate 9: Threaded onto the outer surface of threaded rod 8, in an L-shape, one end connected to fixed ring 12, the other end sliding within limiting groove 10. Driven by threaded rod 8, it moves axially, causing fixed ring 12 and cleaning ring 13 to move synchronously. At the same time, limiting groove 10 constrains its movement direction, ensuring smooth movement of the cleaning assembly.

[0042] Limiting groove 10: It is formed on the inner wall of the water storage tank 2 and cooperates with the limiting plate 9 to provide a guide track for the movement of the limiting plate 9, limit its movement trajectory, prevent the limiting plate from deviating or shaking during the movement, and ensure that the cleaning component moves stably along a straight line.

[0043] Liquid level sensor 11: Installed inside water storage tank 2, this "water level monitor" monitors changes in the water level in the tank in real time and converts the liquid level information into an electrical signal, which is then transmitted to the external control system. When an abnormal water level occurs, it triggers an early warning mechanism and is the core component for realizing the liquid level early warning function.

[0044] Fixed ring 12: The mounting carrier of cleaning ring 13. The inner wall is slidably connected to cleaning ring 13, allowing the cleaning ring to move up and down. A threaded hole 15 is opened on one side, which cooperates with locking bolt 16 and fixing groove 14 of cleaning ring 13 to fix and unlock the cleaning ring, which facilitates the installation and maintenance of cleaning ring.

[0045] Cleaning ring 13: A soft brush is installed on the inner wall, which slides in contact with the outer surface of the liquid level sensor 11. It moves up and down under the drive of the drive motor 7 and the threaded rod 8. The soft brush cleans the impurities attached to the surface of the liquid level sensor, preventing the impurities from affecting the sensor's monitoring accuracy and ensuring its normal operation.

[0046] Fixed groove 14: It is formed on one side of the cleaning ring 13 and cooperates with the threaded hole 15 and locking bolt 16 of the fixed ring 12. When the locking bolt is screwed in, it is embedded in the fixed groove, which firmly fixes the cleaning ring on the fixed ring, preventing the cleaning ring from loosening during movement and ensuring the stable progress of the cleaning work.

[0047] Threaded hole 15: Located on one side of the fixing ring 12, it is threadedly connected to the locking bolt 16. By tightening or loosening the locking bolt, the cleaning ring 13 can be fixed and unlocked, which facilitates the installation, disassembly and position adjustment of the cleaning ring.

[0048] Locking bolt 16: Threaded into the threaded hole 15 of the retaining ring 12, with one end engaging with the retaining groove 14 of the cleaning ring 13. Tightening securely fixes the cleaning ring, while loosening releases the fixation, facilitating the replacement and maintenance of the cleaning ring. It is an important component ensuring the normal operation of the cleaning assembly.

[0049] Inspection door 17: Located on the outer surface of water storage tank 2, it is the "entry point" for equipment maintenance. When it is necessary to replace the cleaning ring 13 or to carry out maintenance on the inside of the water storage tank, the inspection door can be opened to facilitate the operation of personnel inside the water storage tank, thereby improving the convenience of equipment maintenance.

[0050] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
