Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a cooling tower with a water circulation function. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant, absorbs heat from a system and discharges it into the atmosphere to lower the water temperature. In some factories, a large amount of flue gas is generated during the production process, and this flue gas has a relatively high temperature.

[0003] In order to prevent the high-temperature flue gas from being discharged into the air and affecting the ecology, it is usually necessary to cool the flue gas through a cooling tower before discharging it into the air. In order to save water resources, most cooling towers are equipped with water circulation devices.

[0004] For example, a cooling tower with a water circulation function disclosed in Chinese patent CN218973269U filters impurities in the flue gas through a filter plate. Water and filter holes of the filter plate will produce a water curtain, which will contact the flue gas more fully, thereby achieving a better cooling effect. At the same time, the filter screen is used to protect the water inlet pipe opening to prevent sludge and impurities generated by dust in the water tank from entering the pump body through the water inlet pipe, thereby ensuring the service life and performance of the pump body and making it more convenient to repair the filter screen later.

[0005] However, a cleaning structure is provided on the left side of the filter screen of the cooling tower, so that when the cooling water in the cooling tower is pumped, the dirt therein will be adsorbed to the left side of the filter screen, clogging the filter screen and affecting the normal pumping of the cooling water.

[0006] For this reason, we urgently need to provide a cooling tower with water circulation function that can clean the filter screen in time. Utility Model Content

[0007] The purpose of the utility model is to provide a cooling tower with a water circulation function to solve the problem proposed in the above-mentioned background technology that a cleaning structure is set on the left side of the filter screen of the cooling tower, so that when the cooling water in the cooling tower is sucked, the dirt therein will be adsorbed to the left side of the filter screen, blocking the filter screen and affecting the normal suction of the cooling water.

[0009] The cooling unit includes a first filter, a water pump, a connecting pipe, a nozzle, a liquid extraction pipe, a connecting ring, a second filter, a support plate, a motor, a scraper and a shield. The first filter is fixedly connected to the middle position of the inner side of the tower body, the water pump is fixedly connected to the lower right end of the tower body, the connecting pipe is fixedly connected to the upper end of the water pump, the nozzle is fixedly connected to the lower end of the connecting pipe away from the water pump at an equal distance, the liquid extraction pipe is fixedly connected to the left end of the water pump, the connecting ring is connected to the outer left end of the liquid extraction pipe, the second filter is fixedly connected to the left side of the connecting ring, the support plate is fixedly connected to the inner bottom end of the tower body at a position to the left of the liquid extraction pipe, the motor is fixedly connected to the upper left end of the support plate, the scraper is fixedly connected to the outer right end of the output shaft of the motor, and the shield is fixedly connected to the left side of the support plate at the outer end of the motor.

Thus, after the connecting ring is threadedly connected to the outer side of the left end of the liquid extraction pipe until the right side of the second filter screen contacts the left side of the liquid extraction pipe, the cooling water entering the liquid extraction pipe can be filtered.

[0011] A further improvement is that the outer right end of the scraper is slidably connected to the left side of the second filter screen. Therefore, when the motor is started and its output shaft rotates to drive the scraper to rotate, the scraper will continuously slide along the left side of the second filter screen, and the left side of the second filter screen can be continuously cleaned to prevent dirt from clogging the left side of the second filter screen.

[0012] A further improvement is that the end of the connecting pipe away from the water pump is located at the upper end of the tower body. Therefore, when the water pump is started, the cooling water at the bottom of the tower body can be pumped into the water pump through the connecting pipe, then enter the connecting pipe, and then sprayed downward from the nozzle to cool and clean the flue gas entering the tower body from the air inlet pipe.

Therefore, after the sealing plate is rotated into the through slot and the moving block is moved to the left end of the fixed block, the threaded rod is threadedly connected to the threaded hole in the fixed block and then to the thread groove in the moving block, so that the fixed block and the moving block can be fixed to the outer side of the threaded rod, and the sealing plate can be fixed to the inner side of the through slot.

[0015] A further improvement is that a rubber pad is fixedly connected to the outer edge of the sealing plate, so that after the sealing plate is fixed to the through groove, the rubber pad on the outer side of the sealing plate contacts the inner side of the through groove, so that the contact between the outer side of the sealing plate and the inner side of the through groove at the front end of the tower body can be kept sealed, thereby preventing cooling water from leaking out of the through groove during cooling operation.

[0016] In summary, the present application discloses a cooling tower with a water circulation function.
