Description

Technical Field

[0001] The utility model relates to the technical field of cooling unit cleaning, and more specifically, to a cooling unit cleaning device. Background Art

[0002] Central air-conditioning chillers are a big energy consumer for any user, so the cooling efficiency of chillers is the most concerned issue for users. Condensers are an important part of chillers, and their heat exchange efficiency directly affects the cooling efficiency of chillers. Although circulating cooling water systems generally use water treatment methods using chemical water stabilizers or electronic processors, when we open the heads of condensers or heat exchangers at any time after running for a period of time, we can see that there is always a layer of slime, scale, rust and other mixtures attached to the inner surface of the tubes. The thermal resistance of this mixture is much greater than the design limit resistance of the central air-conditioning condenser, which reduces the refrigeration efficiency of the chiller and increases energy consumption. The existing traditional method of removing dirt is chemical cleaning and periodic mechanical brushing, which has certain damage to pipelines and heat exchangers.

[0003] In this regard, China applied for patent number: CN201822106772.X, which discloses a rubber ball cleaning device for condenser cooling pipes of steam turbine generator sets, including a distributor, a ball loading chamber, a rubber ball pump, a ball collecting net and a secondary filter screen, the shaft sleeve is rotatably connected to a rotating shaft inside, the surface of the rotating shaft and the inside of the ball collecting net shell are fixedly connected with a grid plate, the bottom side of the surface of the ball collecting net shell is connected to a ball collecting pipe, the surface side of the grid plate and the position of the ball collecting pipe are fixedly connected with a guide plate, the bottom side of the surface of the rotating shaft is fixedly connected with a handle, the direction of the grid plate is consistent with the direction of the water flow, and a locking device is provided between the two sides corresponding to the lock plate and the handle. The utility model relates to the field of rubber ball cleaning technology. The rubber ball cleaning device for condenser cooling pipes of steam turbine generator sets achieves a high rubber ball recovery rate and a locking effect, has a simple structure, is easy to use, reduces manual labor, has a high rubber ball recovery rate, a good cleaning effect, and improves work efficiency.

[0004] The cooling pipe can be cleaned better by setting a rubber ball cleaning device. However, the cleaning device cannot clean the rubber balls during use, so they are collected in the grid plate and put into use again. The surface of the used rubber balls is adhered to the mixture, and when used again, the mixture is brought into the device, causing the mixture to accumulate inside the device, increasing the frequency of maintenance.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a cleaning device for a cooling unit. Utility Model Content
