[0020] The utility model discloses a water inlet treatment device for filtering and exhausting cooling water entering a cooling tower, so that the cooling water entering the cooling tower has a stable water flow and clean water quality. The water inlet treatment device has a water inlet, which is arranged below the water inlet treatment device. One or more water outlets are arranged according to actual needs. In the utility model, there are two water outlets, which are arranged at the side of the water inlet treatment device. The water inlet is connected to the external cooling water network through a pipeline, and the side water outlet is connected to the water distributor in the pipeline cooling tower. The water inlet treatment device is composed of a molded shell as the main body, the inside of the shell is a cavity, a filter cartridge is installed in the cavity, the filter cartridge is fixed on the shell, the bottom of the shell is the water inlet, the two sides are the water outlets, and the top is the exhaust port. The bottom end of the filter cartridge is fixed on the shell, and the inside of the shell has a water receiving and fixing part for fixing the filter cartridge, which is mainly used to fix the filter cartridge and to receive and store the water filtered from the filter cartridge. A sealing structure is arranged above the filter cartridge so that the cooling water cannot overflow from the top. In order to exhaust the cooling water, an exhaust hole is also arranged above the sealing mechanism. The float in the utility model is arranged in the filter cartridge. When there are bubbles in the cooling water, the float rises with the bubbles during the exhaust process of the exhaust hole. When the gas is exhausted, it blocks the exhaust hole at the top, so that the cooling water cannot flow out through the exhaust hole. At the same time, in order to prevent the float from falling from the lower water inlet when there is no cooling water delivery, a crossbeam is provided at the water inlet to prevent it from falling. Under the pumping of the water pump, the external cooling water enters the water inlet treatment device from the lower water inlet, and then enters the filter cartridge. Under the action of water pressure, it is filtered through the filter holes on the cylinder body and retained in the water receiving fixed part, and then transported to the water distributor of the cooling tower from the side water outlets on both sides. In this way, after being filtered through the filter holes, the dirt and impurities in the cooling water are retained in the water inlet treatment device.

[0021] like Figure 5 As shown, Figure 5 for Figure 3 An enlarged schematic diagram of part A in the figure; as to how the water receiving and fixing part realizes water receiving and fixing the filter cartridge, preferably, the water receiving and fixing part 114 includes an annular water receiving plate 115 integrally connected to the inner wall of the shell 11 and an annular groove 116 integrally connected to the annular water receiving plate 115, and the bottom end of the cylinder body 121 is clamped and fixed in the annular groove 116.

[0022] The water receiving fixing part is a functional structure extending from the inside of the shell, and is composed of an annular water receiving plate and an annular groove extending from the inner wall of the shell. The annular groove fixes the cylinder body of the filter cartridge. The cooling water filtered from the filter holes of the filter cartridge is stored in the annular water receiving plate between the cylinder body and the inner wall of the shell. When the cooling water overflows from the annular water receiving plate, the cooling water is transported to the cooling tower from the side water outlet.

[0023] In order to further improve the fixing strength of the filter cartridge, preferably, the filter cartridge 12 also includes a rubber strip 124, and the rubber strip 124 is adhered and fixed to the bottom end portion of the cylinder body 121, and the bottom end of the cylinder body 121 adhered with the rubber strip 124 is clamped and fixed in the annular groove 116.

[0024] Rubber strips are glued to the lower part and the bottom end of the filter cartridge body, and the filter cartridge body is clamped in the annular clamping groove, so that the friction resistance between the filter cartridge and the shell is greater and the fixing strength is also greater.

[0025] In order to reduce the filtering resistance of cooling water from the filtering hole, preferably, the filtering hole 123 is located higher than the side water outlet 113 .

[0026] The filter hole is arranged in the middle and upper part of the filter cylinder, so that the cooling water is sprayed out from the filter hole in the middle and upper part. The height of the filter hole is higher than the height of the side water outlet. The cooling water sprayed out of the filter hole directly falls on the receiving area of ​​the annular water receiving plate without being sprayed inside the receiving area, thereby reducing the filtering resistance of the cooling water from the filter hole.

[0027] Compared with the prior art, the beneficial effects of the utility model are: by using the water inlet treatment device, the dirt and impurities in the cooling water in the circulation system can be effectively filtered out, and the device is convenient to disassemble, clean and maintain; by arranging an exhaust hole above the filter cartridge, the bubbles entering the filter cartridge can be discharged. After the bubbles are discharged, the pulse fluctuation of the cooling water flow is avoided, which causes uneven water distribution, and the exhaust hole is blocked by the floating ball to prevent water backflow.

[0028] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The above embodiments only express the preferred implementation of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
