Description

Technical Field

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

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. The cooling is to use water and air flow to exchange heat to produce steam, and the steam evaporates and takes away the heat to achieve evaporative heat dissipation, convection heat transfer, and radiation heat transfer. The evaporative heat dissipation device dissipates the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature to ensure the normal operation of the system. The device is generally barrel-shaped, so it is called a cooling tower. In the smelting process of molybdenum, a cooling tower is needed to cool the circulating water used in molybdenum production to save water resources. In the Chinese utility model patent (CN202020410332.8), the problem that impurities are easily precipitated and difficult to clean when draining water from a traditional cooling tower is solved. However, in actual production, the conventional cooling tower drainage device in the prior art is only provided with a filter screen. As the cooling time increases, the mesh of the filter screen is easily clogged by impurities in the cooling water in the cooling tower, resulting in inability to continue normal drainage. The cooling tower needs to be shut down to pump out the water in the cooling tower and clean the filter screen before drainage can continue. The operation is cumbersome and greatly reduces the cooling and drainage efficiency of the cooling tower. Utility Model Content

[0003] In view of this, the utility model provides a cooling tower drainage device. The utility model can filter impurities in the water cooled in the tower body of the cooling tower through the filtering component in the drainage mechanism, and can clean the impurities blocked on the filtering component through a rotatable cleaning component, and discharge the filtered cooling water through the drainage component. The filtering component can be unblocked and cleaned without pumping out the water in the cooling tower after blocking, which greatly reduces the frequency of filter screen blockage and greatly improves the drainage efficiency of the drainage component.

The traditional cooling tower drainage device only sets one filter mesh, and as the cooling time increases, the mesh of the filter mesh is easily blocked by impurities in the cooling water in the cooling tower, resulting in the inability to continue normal drainage.

[0008] The drainage assembly includes a water storage tank arranged at the lower part of the water outlet, and a plurality of drainage holes are opened on the outer wall of the water storage tank. The water storage tank is convenient for temporarily storing the cooling water filtered by the filter plate in the water outlet. The filtered cooling water can be collected through a collection bucket connected to the drainage holes, which is more convenient.

[0009] A transparent observation window is arranged on the outer wall of the water tank, through which the water level in the water tank can be observed to determine whether the filter holes of the filter plate are blocked, so as to make timely response and make operation more convenient.

[0010] The dredging rod is a rubber rod. The purpose of this is that the rubber rod has a certain toughness, which makes it easy for the rubber rod to scrape and clean the impurities blocked in the filter holes on the filter plate, thereby achieving a better dredging effect.

[0029] The use of the utility model:

[0030] First of all, it should be made clear that the drainage device involved in the utility model is mainly used for discharging and collecting the cooled water in the cooling tower. The utility model takes the working principle of the drainage mechanism 300 in the drainage device as an example to explain its use method in detail. When the water in the cooling tower is cooled, the switch valve at the water outlet 200 is opened, and the cooled water will pass through the filter holes 312 on the filter plate 311 to filter the water flowing through the water outlet 200 inside the tower body 100 of the cooling tower, so as to prevent the impurities in the cooled water from being discharged together with the cooling water, thereby reducing the content of impurities in the cooling water, and then discharge it through the water outlet 200 of the drainage component 330. When the main line of the filter hole 312 on the filter plate 311 is blocked, it can be seen through the transparent observation window that the water level in the water storage tank 331 is lower than the height of the water outlet 200, and then the output shaft of the motor 322 is started to rotate, and the rotation of the output shaft of the motor 322 drives the rotating shaft 321 to rotate together, and the rotation of the rotating shaft 321 can drive the fixed When the fixed ring 323 and the scraper 324 on the outside of the fixed ring 323 and the dredging rod 325 at the bottom of the scraper 324 rotate together, the dredging rod 325 can clean the impurities blocked on the filter plate 311. In addition, with the rotation of the dredging rod 325 and the scraper 324, the cooling speed of the cooling water can be accelerated, and the impurities in the cooling water can be suspended, which greatly reduces the frequency of clogging of the filter holes 312 on the filter plate 311. Then the drainage treatment can continue. The utility model can filter the impurities in the water cooled in the tower body 100 of the cooling tower through the filter component 310 in the drainage mechanism 300, and can clean the impurities blocked on the filter component 310 through the rotatable cleaning component 320, and discharge the filtered cooling water through the drainage component 330. The dredging and cleaning operation of the filter component 310 does not need to be pumped out of the blocked water in the cooling tower, which greatly reduces the frequency of filter mesh clogging and greatly improves the drainage efficiency of the drainage component 330. The invention solves the problem that the traditional cooling tower drainage device is only provided with a filter screen. As the cooling time increases, the mesh of the filter screen is easily blocked by impurities in the cooling water in the cooling tower, resulting in the inability to continue normal drainage. It is necessary to stop the cooling tower to pump out the water in the cooling tower and clean the filter screen before continuing to drain the water. The operation is troublesome and greatly reduces the cooling and drainage efficiency of the cooling tower.
