Description

Technical Field

[0001] This utility model is a descaling device for a circulating cooling water tank, belonging to the field of cooling water systems. Background Technology

[0002] During long-term operation, circulating cooling water tanks gradually accumulate calcium and magnesium ions, microbial metabolites, and suspended impurities, forming a hardened layer of scale and biological slime. This scale reduces the tank's heat dissipation efficiency and affects the stable operation of the entire cooling system. Installing an ion exchanger between the return water pipe and the tank reduces the concentration of calcium and magnesium ions in the water, thus minimizing scale formation. After the used cooling water returns to the tank, an axial flow fan generates airflow to cool the returning water. During this process, the amount of cooling water in the tank decreases, necessitating the installation of a float valve on one side of the tank. The float valve plays a crucial role in water level control, but its rotating parts are constantly susceptible to contamination by debris.

[0003] The slimy biofilm formed by the continuous growth of microorganisms in the water tank, along with silt, rust debris, and slowly precipitated calcium and magnesium ions, all accumulate at rotating parts such as the connecting rod hinge points and the gaps between the valve stem and the valve body. This makes the originally flexible rotation sluggish, and the valve's opening or closing action noticeably slow, as if being dragged by an invisible resistance. Over time, the adhered debris gradually thickens and hardens, accumulating into scale in the tiny rotating gaps, making it difficult for the connecting rod to swing smoothly, and the valve stem often gets stuck during opening and closing. When these obstacles reach a certain level, the float valve loses its ability to precisely control the flow. Even if the water level in the tank has risen to the overflow outlet, the valve cannot close in time, and a large amount of water continues to gush out from the overflow outlet, resulting in unnecessary loss.

[0004] Overflowing water not only wastes resources but also flows down the outer wall of the tank, wetting the surrounding environment and accelerating the corrosion of metal parts. If the overflow flows near electrical equipment, it may also pose a safety hazard. To alleviate this problem, the float valve must be disassembled and cleaned regularly. However, frequent disassembly and assembly will aggravate the wear of rotating parts, making the gaps larger and more prone to accumulating debris, leading to a dilemma of repeated maintenance that is difficult to resolve completely. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a descaling device for circulating cooling water tanks to solve the problems mentioned in the background technology. This utility model reduces labor costs and improves the reliability of cooling water system operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a descaling device for a circulating cooling water tank, comprising:

[0007] A water tank has a ventilation chamber installed on one side of its upper end. The ventilation chamber has a top cover installed on its upper surface. Multiple ventilation holes are opened on both parallel sides of the ventilation chamber. A removable tank cover is installed on the side of the upper end of the water tank away from the ventilation chamber.

[0008] An ion exchanger is installed on one side of the ventilation chamber. A liquid outlet pipe is installed at the lower end of the ion exchanger. The lower end of the liquid outlet pipe passes through the top cover and remains in a fixed relative position with the top cover.

[0009] A water supply valve is installed on the lower part of one side of the water tank, and a handle is installed on the valve stem of the water supply valve.

[0010] A float is installed inside the water tank, and the float is movably connected to the handle via a connector.

[0011] Furthermore, the connector includes:

[0012] The vertical shaft is fixed to the float at its lower end. A guide hole is opened on the upper surface of the groove cover. The upper end of the vertical groove extends through the guide hole to the upper side of the groove cover.

[0013] A circular shaft is arranged horizontally, and one end of the circular shaft is connected and fixed to the upper end of the vertical shaft;

[0014] The upper end of the connecting plate is rotatably connected to the end of the circular shaft away from the vertical axis.

[0015] An inclined plate, one end of which is rotatably connected to the lower end of a connecting plate, and the end of the inclined plate away from the connecting plate is rotatably connected to the end of the handle away from the water supply valve via a connecting shaft;

[0016] The counterweight is rotatably mounted on the connecting shaft.

[0017] Furthermore, a lifting lug that is rotatably connected to the connecting shaft is sleeved on the connecting shaft, and a counterweight is installed at the lower end of the lifting lug.

[0018] Furthermore, a circulation pump is installed on the upper surface of the tank cover. The inlet end of the circulation pump extends to the lower part of the tank. A one-way valve is installed at the outlet end of the circulation pump. The one-way valve is open in the direction away from the circulation pump. A shut-off valve is installed at the end of the one-way valve away from the circulation pump. A pipe joint for connecting to the cooling water supply pipeline is installed at the end of the shut-off valve away from the one-way valve.

[0019] Furthermore, a support is installed at the bottom of the water tank, and support legs are installed at the four corners of the lower surface of the support;

[0020] Furthermore, two brackets are installed on the upper surface of the support, and the upper ends of the two brackets are connected and fixed by positioning sleeves. The positioning sleeves are fitted onto the ion exchanger and are fixed in a relative position to the ion exchanger.

[0021] Furthermore, a cylindrical ring for mounting an axial flow fan is installed on the upper surface of the top cover, and the cylindrical ring communicates with the interior space of the ventilation chamber.

[0022] Furthermore, the water supply valve is arranged horizontally, with one end of the water supply valve connected to the water tank via a first bend pipe, and the end of the water supply valve away from the first bend pipe is equipped with a second bend pipe for connecting to the ion exchanger.

[0023] The beneficial effects of this utility model are:

[0024] The ion exchanger adsorbs calcium and magnesium ions in the water through resin, and then sends the softened water into the water tank through the outlet pipe, reducing the material basis for scale formation at the source. With the stable fixation of the positioning sleeve and bracket, it ensures long-term efficient operation.

[0025] The float in the water tank rises and falls with the water level. Through the connecting parts formed by the vertical shaft, connecting plate, and inclined plate, it drives the handle of the water supply valve to rotate. When the water level drops, the float sinks and triggers the handle to open the water supply valve. When the water level rises again, the float rises and drives the handle to close the water supply valve. The entire process requires no manual intervention, completely replacing manual inspection and operation, reducing labor costs. The lugs on the connecting shaft and the counterweight work together to balance the force on the connecting parts formed by the vertical shaft, connecting plate, and inclined plate, ensuring that the water supply valve opens and closes accurately and sensitively, avoiding water supply delays or over-watering due to insufficient buoyancy. In this case, only the float is in the water tank, and the water supply valve and the connecting parts that control the rotation of the handle in the water supply valve are also outside the water tank, preventing debris in the water from affecting the normal opening and closing of the water supply valve and improving reliability.

[0040] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0041] Please see Figure 1 , Figure 2 and Figure 4This utility model provides a technical solution: a descaling device for a circulating cooling water tank, including a tank 1, a support 2 installed at the bottom of the tank 1, support legs 21 installed at the four corners of the lower surface of the support 2, a ventilation chamber 11 installed on one side of the upper end of the tank 1, a top cover 12 installed on the upper surface of the ventilation chamber 11, and multiple ventilation holes 14 opened on the two parallel sides of the ventilation chamber 11. A detachable tank cover 15 is installed on the upper end of the tank 1 away from the ventilation chamber 11, and a cylindrical ring 13 for installing an axial flow fan is installed on the upper surface of the top cover 12. The cylindrical ring 13 communicates with the internal space of the ventilation chamber 11. An ion exchanger 4 is installed in the tank. On one side of the ventilation chamber 11, an outlet pipe 43 is installed at the lower end of the ion exchanger 4. The lower end of the outlet pipe 43 passes through the top cover 12 and remains in a fixed relative position to the top cover 12. Two brackets 42 are installed on the upper surface of the support 2. The upper ends of the two brackets 42 are connected and fixed by a positioning sleeve 41. The positioning sleeve 41 is fitted onto the ion exchanger 4 and remains in a fixed relative position to the ion exchanger 4. As the core component of the system for inhibiting scale formation, the ion exchanger 4 is filled with ion exchange resin that can efficiently adsorb calcium and magnesium ions in the water. Through ion replacement reaction, it reduces the hardness of the circulating water and fundamentally breaks the material chain of scale formation. The treated softened water is transported through the outlet pipe 43 at the lower end, passes through the top cover 12 of the ventilation chamber 11, and is injected into the water tank 1, providing a low-hardness water source for the entire circulation system and continuously reducing the deposition of scale on the inner wall of the water tank 1 and in the pipes.

[0042] To ensure the long-term stable operation of the ion exchanger 4, two supports 42 on the upper surface of the support 2 form a stable support. The positioning sleeve 41 at the upper end of the support 42 is tightly fitted onto the outer wall of the ion exchanger 4, and is fixed in relative position with the ion exchanger 4 through a rigid connection. This effectively resists the vibration and impact during equipment operation and avoids loosening of pipe interfaces or uneven distribution of resin layer due to displacement. This fixing method not only ensures the sealing of the connection between the ion exchanger 4 and the outlet pipe 43 and the water supply valve 6, but also maintains sufficient contact between the resin layer and the water flow, ensuring long-term stable softening efficiency. This allows for continuous anti-scaling at the source, extending the cleaning cycle and service life of the water tank 1 and the entire cooling system.

[0043] See Figures 1-5The water supply valve 6 is installed on the lower part of one side of the water tank 1. The water supply valve 6 is arranged horizontally. One end of the water supply valve 6 is connected to the water tank 1 through the first bend pipe. The end of the water supply valve 6 away from the first bend pipe is equipped with a second bend pipe for connecting the ion exchanger 4. A handle 61 is installed on the valve stem of the water supply valve 6. The float ball 3 is set in the water tank 1. The lower end of the vertical shaft 31 is connected and fixed to the float ball 3. A guide hole is opened on the upper surface of the tank cover 15. The upper end of the vertical shaft 31 extends through the guide hole to the upper side of the tank cover 15. The round shaft 32 is arranged horizontally. One end of the round shaft 32... The upper end of the vertical shaft 31 is fixedly connected to the upper end of the connecting plate 33, and the upper end of the connecting plate 33 is rotatably connected to the end of the round shaft 32 away from the vertical shaft 31. One end of the inclined plate 34 is rotatably connected to the lower end of the connecting plate 33. The end of the inclined plate 34 away from the connecting plate 33 is rotatably connected to the end of the handle 61 away from the water supply valve 6 through the connecting shaft. The float ball 3 inside the water tank 1 floats on the water surface and can move synchronously with the rise and fall of the water level in the water tank 1. It forms a mechanical transmission relationship with the handle 61 of the water supply valve 6 through the linkage connecting parts composed of the vertical shaft 31, the round shaft 32, the connecting plate 33 and the inclined plate 34. When the water level in tank 1 drops due to evaporation or circulation, the float 3 sinks, causing the vertical shaft 31 to slide downwards along the guide hole of the tank cover 15. The circular shaft 32 pulls the connecting plate 33 downwards, which in turn pushes the inclined plate 34 to rotate the handle 61 around the valve stem of the water supply valve 6, opening the water supply valve 6 channel. The softened cooling water is then injected into tank 1 through the pipeline. When the water level rises back to the preset height, the float 3 floats up, the vertical shaft 31 moves upwards, the circular shaft 32 pulls the connecting plate 33 upwards, and the inclined plate 34 drives the handle 61 to rotate in the opposite direction, causing the water supply valve 6 to automatically close and stop water supply.

[0044] This entire mechanical linkage mechanism relies entirely on water level changes to trigger the opening and closing of the water supply valve 6. No manual supervision or operation is required throughout the process. This not only avoids potential oversights during traditional manual inspections (such as untimely or excessive water replenishment) but also completely replaces the manual switching of the water supply valve 6, reducing labor costs. Simultaneously, the guide hole's limiting effect on the vertical shaft 31 and the rotational coordination of each connecting component ensure the accuracy and stability of the water replenishment action, maintaining the water level in the tank 1 within a suitable range and guaranteeing the continuous and stable operation of the circulating cooling system.

[0045] See Figure 1 , Figure 3 , Figure 4 and Figure 5A lifting lug 71 is fitted onto the connecting shaft and rotatably connected to it. A counterweight 7 is installed at the lower end of the lifting lug 71. The lifting lug 71 on the connecting shaft cooperates with the counterweight 7 to balance the force on the connecting parts formed by the vertical shaft 31, the connecting plate 33, and the inclined plate 34, ensuring that the water supply valve 6 operates accurately and sensitively, and avoiding water supply delay or over-watering due to insufficient buoyancy. In this case, only the float 3 is in the water tank 2, and the water supply valve 6 and the connecting parts that control the rotation of the handle 61 in the water supply valve 6 are also outside the water tank 1, preventing debris in the water from affecting the normal opening and closing of the water supply valve 6 and improving reliability.

[0046] See Figure 1 , Figure 2 and Figure 4 A circulation pump 5 is installed on the upper surface of the tank cover 15. The inlet end of the circulation pump 5 extends to the lower part of the water tank 1, and a one-way valve 53 is installed at the outlet end of the circulation pump 5. The one-way valve 53 is open in the direction away from the circulation pump 5. A shut-off valve 52 is installed at the end of the one-way valve 53 away from the circulation pump 5, and a pipe connector 51 for connecting to the cooling water supply pipeline is installed at the end of the shut-off valve 52 away from the one-way valve 53. The circulation pump 5 draws water out of the water tank 1 and delivers it to the cooling pipeline through the one-way valve 53 and the pipe connector 51, forming a closed loop. This reduces the mixing of external impurities, lowers the probability of biological slime and suspended impurities deposition, and slows down the rate of scale formation.

[0047] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
