There are three positioning rods 121 distributed in a ring shape with equal distances. A fixing ring 122 is welded inside the filter shell 3, and three groups of countersunk holes 123 are opened on both sides of the fixing ring 122. Pushing components 124 are welded inside the three groups of countersunk holes 123.

[0024] As a technical optimization scheme of the utility model, two groups of filter elements 120 are provided to filter impurities in water, thereby improving the cooling effect of the cooling tower body 1, and positioning rods 121 are provided to fix the positions of the two groups of filter elements 120 inside the filter housing 3 to prevent the two groups of filter elements 120 from moving under the impact of water pressure.

[0025] refer to Figure 3 The pushing assembly 124 includes a spring 1240 , and three groups of pushing blocks 1241 are arranged on both sides of the fixed ring 122 . One end of the spring 1240 is welded inside the three groups of countersunk holes 123 , and the other end of the spring 1240 is welded to the side of the three groups of pushing blocks 1241 close to the fixed ring 122 .

[0026] As a technical optimization solution of the utility model, by setting the cooperation between the spring 1240 and the three groups of push blocks 1241, when replacing the two groups of filter elements 120, the object can be automatically pushed out from the inside of the three groups of countersunk holes 123, and at the same time it also has the function of tightening the two groups of filter elements 120.

[0027] refer to Figure 2 and Figure 3 One end of the two groups of filter elements 120 is sleeved inside the card slot 11, the positioning rod 121 is inserted into the three groups of countersunk holes 123, and one end of the positioning rod 121 is in contact with the push block 1241.

[0031] refer to Figure 2 The sealing groove 9 is arranged in a circular shape, the sealing ring 10 is arranged in a circular shape, and the sealing ring 10 is made of rubber material.

[0032] As a technical optimization solution of the present invention, a sealing ring 10 made of rubber material is provided to have good elasticity and sealing effect, thereby preventing leakage of filtered water.

[0033] The working principle and use process of the utility model are as follows: when in use, the sealing ring 10 is sleeved inside the sealing groove 9, and then one end of the two groups of filter elements 120 is sleeved inside the card groove 11, the positioning rod 121 is inserted into the three groups of countersunk holes 123, and then the sealing plate 5 is pressed against one side of the filter housing 3, the positions of the through hole 1 4 and the through hole 2 6 are aligned with each other, the bolt 7 passes through the through hole 1 4 and the through hole 2 6, and then the nut 8 is threadedly connected with the bolt 7. After the nut 8 is tightened, the gap between the sealing plate 5 and the filter housing 3 is sealed to prevent water seepage. When the two groups of filter elements 120 need to be replaced, the nut 8 is unscrewed from the bolt 7, and the handle 50 is pulled. When the sealing plate 5 is separated from the filter housing 3, the spring 1240 pushes the push block 1241 to move through its own elasticity, and the push block 1241 pushes the positioning rod 121 out of the three groups of countersunk holes 123, and then the two groups of filter elements 120 are separated from the filter housing 3.

[0034] To sum up: this filtering device of a chemical cooling tower, by setting the cooperation of the sealing groove 9 and the sealing ring 10, is used to seal the gap between the filter housing 3 and the sealing plate 5 to prevent the filtered water from leaking.
