Description

Technical Field

[0001] The utility model relates to the technical field of closed cooling towers, in particular to a spray device of a closed cooling tower. Background Art

[0002] A closed cooling tower is a cooling device used in industrial production processes. Its working principle is to achieve cooling effects through heat exchange between water and air. Unlike an open cooling tower, a closed cooling tower does not come into contact with the external environment during the cooling process, so it can reduce water evaporation and pollution risks. A closed cooling tower is mainly composed of a cooling tower body, a cooling water circulation system, a cooling medium, a cooling fan, etc. The cooling water circulates in the cooling tower body, and the air introduced by the cooling fan exchanges heat with the cooling water to take away the heat, thereby achieving a cooling effect. The cooling medium can be water, ethylene glycol, etc. Since it does not come into contact with the external environment, the evaporation of cooling water in a closed cooling tower is low, which saves water resources. A closed cooling tower can reduce the pollution risk of cooling water and reduce the impact on the environment. The closed cooling tower has high operational safety and can ensure the stability of the industrial production process. Closed cooling towers play an important role in industrial production and can provide reliable cooling effects while protecting the environment and saving resources.

[0003] In the prior art, when a closed cooling tower is in use, its multiple cooling water nozzles are exposed to a large amount of substances. After long-term use, some nozzles may become clogged. In order to facilitate the inspection and dredging of the nozzles, we propose a spray device for a closed cooling tower. Utility Model Content

[0007] Preferably, the positioning device includes a fixing plate fixedly connected to the other end of the water collecting plate, two second magnetic plates are fixedly connected to the side wall of the fixing plate, and a plurality of first magnetic plates are fixedly connected to the side wall of the positioning plate, and the plurality of first magnetic plates and the corresponding plurality of second magnetic plates are magnetically attracted to each other.

[0008] Preferably, the guide device includes two guide rods fixedly connected to the side wall of the positioning plate, and guide grooves are provided through the two water collecting plates at corresponding positions. Both guide rods penetrate the fixed plate and are slidably connected in the corresponding guide grooves, and the guide grooves are not connected to the water trough inside the water collecting plate.

[0009] Preferably, a sealing gasket is provided at the side wall of the sealing plate.

[0010] Preferably, the size of the fixing plate is equal to the size of the opening.

[0011] Preferably, a handle is fixedly connected to the outer side wall of the sealing plate.

[0012] Preferably, the two guide rods will not disengage from the corresponding guide grooves.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] In the utility model, by setting a positioning device and a guiding device to cooperate with each other, the water collecting plate and multiple nozzles arranged in the cooling tower can be pulled out of the corresponding water collecting plate by pulling the sealing plate once, so that the multiple nozzles are exposed, so that the operator can easily clear the corresponding nozzles in time. When the water collecting plate moves outward, the corresponding guide rod can prevent the water collecting plate from tilting. When the water collecting plate is fully pulled out, the corresponding fixed plate will come to the opening. At this time, the guide rod just moves to the maximum distance in the guide groove, and the multiple nozzles are fully exposed. The fixed plate plays a role of temporarily blocking the opening.
