Description

Technical Field

[0001] This utility model relates to the field of cooling towers, and in particular to an adjustable cooling tower water-blocking structure. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and release it into the atmosphere to lower the water temperature. Its cooling effect is achieved by the heat exchange between water and air flow to generate steam. The steam evaporates and carries away the heat, thus dissipating the waste heat generated in industrial processes or refrigeration and air conditioning systems to lower the water temperature and ensure the normal operation of the system. The device is generally barrel-shaped, hence the name cooling tower.

[0003] In an open cooling tower, the cooled liquid enters an open space, where it is sprayed into the cooling space through nozzles via a delivery pipe. With the help of the cooling airflow generated by the circulating fan (airflow is transported from bottom to top), the liquid exchanges heat with the cold air during the transport process, and the cooled liquid falls into the recovery chamber.

[0004] During the use of the cooling tower, the liquid level of the treatment fluid in the recovery chamber needs to be monitored. If the liquid level is too high, the treatment fluid will flow out from the airflow inlet, which will waste resources. However, since it often takes time to close the valve of the delivery pipe, some treatment fluid will still flow out from the airflow inlet.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] To address the aforementioned deficiencies, the purpose of this utility model is to provide an adjustable cooling tower water-blocking structure, which can set the guide plate as a movable structure, and use a sensing push plate to sense the liquid level in the recovery chamber, and further block the air inlet as needed to increase the liquid storage capacity of the equipment.

[0007] To achieve the above objectives, this utility model provides an adjustable cooling tower water-blocking structure, including a cooling chamber and a recovery chamber from top to bottom; the cooling chamber has an air inlet on its side wall, and a guide plate is installed at the air inlet. A drive unit is provided on one side of the guide plate to sense the liquid height and drive the guide plate to switch angles; after the angle is switched, the guide plate enters a blocking state from an inclined state to cover the air inlet.

[0008] According to the adjustable cooling tower water-blocking structure of this utility model, the air inlet is installed at the air inlet in a hinged manner.

[0009] According to the adjustable cooling tower water-blocking structure of this utility model, the driving part is a sensing push plate that is set at an angle to the guide plate.

[0010] According to the adjustable cooling tower water-blocking structure of this utility model, the sensing push plate is provided with a float structure, which senses the buoyancy of the water to generate a driving force to drive the guide plate to switch operation.

[0011] According to the adjustable cooling tower water-blocking structure of this utility model, the cooling chamber wall and the two sides of the sensing push plate are provided with baffles, which are semi-circular.

[0012] According to the adjustable cooling tower water-blocking structure of this utility model, the float structure is an airbag.

[0013] This utility model provides an adjustable cooling tower water-blocking structure, including a cooling chamber and a recovery chamber from top to bottom. The cooling chamber has an air inlet on its side wall and a water spray pipe and guide vanes inside. A guide vane is installed at the air inlet, which is hinged to the air inlet. During operation, the guide vane can swing up and down around the hinge point. In its normal state (when the liquid level in the recovery chamber is below a preset value), the guide vane is tilted. In this state, the guide vane mainly increases the angle of the introduced airflow, allowing the cooling airflow entering from the air inlet to fully contact the liquid being cooled, increasing heat exchange efficiency. It also blocks some impurities (such as stones). A drive unit is provided on one side of the guide vane to sense the liquid level and drive the guide vane to switch angles. After the angle is switched, the guide vane moves from the tilted state to a sealed state, closing the air inlet. When the guide plate is in a blocked state, it completely blocks the air inlet, preventing liquid levels above the inlet from draining out, thus providing temporary storage. This invention allows the guide plate to be configured as a movable structure, working in conjunction with a sensing push plate to detect the liquid level in the recovery chamber, further blocking the air inlet as needed to increase the equipment's liquid storage capacity.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0020] See Figure 1 , Figure 2 and Figure 3 This utility model provides an adjustable cooling tower water-blocking structure, which includes a cooling chamber 11 and a recovery chamber 12 from top to bottom; the cooling chamber 11 is provided with an air inlet 2 on its side wall, and is provided with a water spray pipe, a guide vane, etc. inside.

[0021] A guide plate 3 is installed at the air inlet 2. Specifically, in this embodiment, the air inlet 2 is installed at the air inlet 2 in a hinged manner. When moving, it can swing up and down around the hinge point. Under normal conditions (when the liquid level in the recovery chamber 12 is lower than the preset value), the guide plate is in an inclined state. In this state, the guide plate is mainly used to increase the elevation angle of the introduced airflow, so that the cooling airflow entering from the air inlet 2 can come into more sufficient contact with the liquid to be processed (the liquid to be cooled), thereby increasing the heat exchange efficiency. On the other hand, it can also block some impurities (such as stones).

[0022] One side of the guide plate 3 is provided with a drive unit that senses the liquid level and drives the guide plate 3 to switch angles; after the angle is switched, the guide plate enters a blocking state from the tilted state to cover the air inlet 2. When the guide plate 3 is in the blocking state and completely blocks the air inlet 2, the liquid level above the air inlet 2 will not be discharged, which can achieve the effect of temporary storage.

[0023] See Figure 2 and Figure 4 In the first embodiment, the driving unit is a sensing push plate 4 arranged at an angle to the guide plate 3. When the liquid level is higher than a preset value, the sensing push plate 4 is pushed upward by water pressure (direction upward), causing it to flip upward and further drive the guide plate 3 to block the air inlet 2. At this time, the liquid level can be higher than the height of the already blocked air inlet 2.

[0024] Preferably, the cooling chamber 11 has baffles 5 on both sides of the sensing push plate 4. The baffles 5 are semi-circular. By setting the baffles 5, the sensing push plate 4 can be pushed upward by water pressure (direction upward), preventing water from flowing into the upper part of the sensing push plate 4 and thus reducing the upward pushing effect.

[0025] See Figure 3In the second embodiment, the driving unit is a sensing push plate 4 arranged at an angle to the guide plate 3. The sensing push plate 4 is equipped with a float structure 6 (which is an airbag), which senses the buoyancy of the water to generate a driving force to switch the operation of the guide plate 3. The buoyancy of the float structure 6 is used as the driving force to drive the guide plate 3 to block the air inlet 2.

[0026] In summary, this utility model provides an adjustable cooling tower water-blocking structure, including a cooling chamber and a recovery chamber from top to bottom. The cooling chamber has an air inlet on its side wall, and a water spray pipe and guide vanes are installed inside. A guide vane is installed at the air inlet, which is hinged to the air inlet. During operation, the guide vane can swing up and down around the hinge point. Under normal conditions (when the liquid level in the recovery chamber is below a preset value), the guide vane is in an inclined state. In this state, the guide vane mainly increases the elevation angle of the introduced airflow, allowing the cooling airflow entering from the air inlet to fully contact the liquid being processed (the liquid to be cooled), increasing heat exchange efficiency. It also blocks some impurities (such as stones). A drive unit is provided on one side of the guide vane to sense the liquid level and drive the guide vane to switch angles. After the angle is switched, the guide vane moves from the inclined state to a sealed state, closing the air inlet. When the guide plate is in a blocked state, it completely blocks the air inlet, preventing liquid levels above the inlet from draining out, thus providing temporary storage. This invention allows the guide plate to be configured as a movable structure, working in conjunction with a sensing push plate to detect the liquid level in the recovery chamber, further blocking the air inlet as needed to increase the equipment's liquid storage capacity.

[0027] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
