Description

Technical Field

[0002] A cooling tower is a device that dissipates the heat generated during industrial production or refrigeration processes into the atmosphere, bringing the heat-carrying medium into full contact with the air or other media for heat exchange, thereby achieving a cooling effect. Traditional YBN counterflow closed cooling towers will discharge a large amount of steam into the atmosphere along with the gas during cooling, and the heat exchange is uneven and cannot fully dissipate the heat.

[0003] A Chinese patent with publication number CN112815738A has been proposed in the prior art to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: The present invention discloses a YBN countercurrent closed cooling tower, comprising a cooling tower shell, the cooling tower shell is in a bottle-mouth shape, and an air outlet is opened on the top of the cooling tower shell, and a motor connected to a power supply is welded to the inner wall of the air outlet through a bracket, and a hole is opened on the upper half of the cooling tower shell from the front and rear ends of the side wall, and a cooling pipe is inserted into the hole.

[0004] Although the device can effectively cool the liquid, after the device has been working for a long time, a large amount of impurities will be mixed in the water collection tank. When the impurities follow the cooling water in the cooling cycle, they will affect the cooling speed of the cooling water itself, resulting in a reduction in the cooling effect of the cooling tower.

DETAILED DESCRIPTION

[0031] The present invention is further described in detail below in conjunction with the embodiments:

[0032] Example 1

[0036] In this embodiment, when the tower shell 29 needs to be repaired, the repair door 23 is opened to repair the components inside the tower shell 29. The shutter 24 is convenient for the repairman to observe the inside of the tower shell 29. A limit plate 3 is installed on the top of the water storage, and a stepper motor 5 is installed in the limit plate 3. A fixed plate 4 is installed opposite to the limit plate 3 to limit the movement of the movable plate 7. A waterproof plate 8 is installed on the top of the movable plate 7 to prevent the stepper motor from getting wet and to prevent the first brush 11 and the second brush 13 from colliding with the water storage tank 1 and the filter plate 14. The stepper motor 5 drives the threaded rod 6 to rotate so that the moving plate 7 moves, and the servo motor 9 drives the rotating rod 10 to rotate the first brush 11. The bottom of the first brush 11 is provided with a connecting plate 12, and the bottom of the connecting plate 12 is provided with a second brush 13.

After the water is discharged, the valve 28 is finally closed, and then replaced with clean water to complete the cleaning.

[0037] Example 2

[0038] like Figure 1-5 As shown, based on Example 1, the utility model provides a technical solution: preferably, a filter plate 14 is fixedly connected to the inner wall of the water reservoir 1.

[0040] In this embodiment, a filter plate 14 is provided in the water reservoir 1 to prevent the spray pump 19 from drawing dirt into the water inlet pipe 20. The outer wall of the water reservoir 1 has four groups of outer shells 15, each of which has a power supply 16. Each power supply 16 is connected to an electric heating rod 17 for heating the water in the water reservoir 1 so that the water can be maintained within five to thirty-five degrees to prevent the circulating water from freezing.
