Description

Technical Field

[0002] In today's industrial production environment, open cooling towers, as key heat exchange equipment, are crucial to the overall production system in terms of operational efficiency and stability. However, cooling tower maintenance, especially cleaning, remains challenging.

[0003] First, existing open cooling towers rely primarily on manual cleaning, requiring workers to carry cleaning equipment into or around the cooling tower to perform manual cleaning. This method is not only labor-intensive and inefficient, but also poses significant safety risks. Working at height increases the risk of falling, and direct contact with cleaning agents and water mist can also pose a health risk to workers. Furthermore, manual cleaning often fails to fully reach every corner of the cooling tower, resulting in suboptimal cleaning results and impacting the cooling tower's heat dissipation efficiency and service life.

[0004] Secondly, the existing cleaning method has serious problems in saving water. In the traditional cleaning process, a large amount of clean water is directly used to flush the cooling tower wall to achieve the decontamination effect. However, this method not only wastes a lot of water resources, but also increases the operating costs of the enterprise.

[0005] Therefore, it is necessary to provide a new cooling tower inner and outer wall flushing device to solve the above technical problems. Utility Model Content

[0033] The working principle of the cooling tower inner and outer wall flushing device provided by the utility model is as follows:

[0034] Initial state and preparation:

[0035] The device is installed near the cooling tower, the support base 1 is placed firmly, and the L-shaped connecting rod 2 is connected to the top of the support base 1 through a sliding connection and is in the initial position (i.e. the lowest point);

[0036] The U-shaped cleaning rod 4 is rotatably connected to the end of the L-shaped connecting rod 2 through a connecting shaft, ensuring that the angle can be flexibly adjusted to meet the cleaning needs of the inner and outer walls of the cooling tower;

[0037] A certain amount of clean water is pre-filled into the water storage tank 5 and connected to the water collection basin 6 through a conduit to form a circulating water system;

[0038] Lifting and positioning:

[0039] Start the electric push rod 3, and its output end pushes the L-shaped connecting rod 2 to slide and rise along the top of the support base 1 until the two ends of the U-shaped cleaning rod 4 are respectively inserted into the inner wall and outer wall of the cooling tower; at this time, the axis of the L-shaped connecting rod 2 coincides with the axis of the cooling tower, ensuring that the cleaning rod can evenly cover the entire wall surface;

[0040] Cleaning process:

[0041] Pour clean water into the overflow chamber to an appropriate water level and start the water pump at the end of the telescopic tube 11; the water pump works to deliver clean water to each nozzle through the telescopic tube 11 and the pipe inside the U-shaped cleaning rod 4;

[0042] The motor 12 is started, driving the driving gear 13 to rotate; since the driving gear 13 is engaged with the driven gear 14, the driven gear 14 rotates accordingly, thereby driving the connecting shaft and the U-shaped cleaning rod 4 to rotate;

[0043] The motor 12 is controlled by a specific program to realize an alternating working mode of rotating clockwise for one circle and then counterclockwise for one circle; this rotation mode helps to clean the cooling tower wall more comprehensively and avoid cleaning dead corners;

[0044] As the motor 12 rotates, the water pump at the end of the telescopic tube 11 starts, and clean water is delivered to the nozzle through the telescopic tube 11 and the U-shaped cleaning rod 4; the nozzle sprays high-pressure water flow onto the inner and outer walls of the cooling tower to flush away dirt;

[0045] The nozzle sprays clean water onto the inner and outer walls of the cooling tower at the same time, forming a high-pressure water flow to effectively wash away dirt, microorganisms and scale on the wall surface;

[0046] During the cleaning process, the flushing water on the inner wall of the cooling tower naturally flows into the water collection basin 6 at the bottom through its internal structure; while the flushing water on the outer wall flows directly down along the wall surface and is also collected in the water collection basin 6;

[0047] Water recycling and reuse:

[0048] The cleaning water collected in the water collection basin 6 is transported back to the water storage tank 5 through the conduit; first it enters the water receiving chamber and collides with the impact plate 9, which slows down the water flow and avoids direct impact on the bottom of the water receiving chamber, while preliminarily removing some impurities;

[0049] Impurities in the cleaning water gradually settle at the bottom of the water receiving chamber and the sedimentation chamber under the action of gravity; when the water level in the sedimentation chamber rises above the second baffle 8, the clean water flows into the overflow chamber through the opening on the baffle, achieving separation of water and impurities;

[0050] The clean water in the overflow chamber is pumped out again by the water pump for the next round of cleaning operation, forming a closed-loop water circulation system. This design not only reduces the waste of water resources, but also reduces the discharge of cleaning wastewater, thus protecting the ecological environment.

[0051] Secondary flushing and end:

[0052] After the initial cleaning is completed, clean water can be added to the overflow chamber as needed for secondary flushing to ensure that the inner and outer walls of the cooling tower are thoroughly cleaned;

[0053] After cleaning is completed, the water pump and the electric push rod 3 are turned off, and the L-shaped connecting rod 2 slowly descends back to the initial position under the action of gravity or the auxiliary mechanism, and the U-shaped cleaning rod 4 is separated from the wall of the cooling tower;

[0054] Operators can remotely monitor the entire cleaning process through a wireless remote control to ensure the safety and efficiency of the operation.

Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
