[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] As Figures 1 to 4 shown, the present invention provides a filter for an underwater engineering low-temperature water tank, including: a device body 1, the device body 1 is composed of an input connector 2, a three-channel filtering device 3, and an output connector 4. The two ends of the three-channel filtering device 3 are respectively connected to the input connector 2 and the output connector 4 and fixed by bolts and nuts; the three-channel filtering device 3 includes a first filtering channel 5, a second filtering channel 6, a third filtering channel 7, and a stabilizing rod 8. Among them, the first filtering channel 5, the second filtering channel 6, and the third filtering channel 7 are distributed horizontally at equal distances. There are two stabilizing rods 8, which are respectively arranged between the first filtering channel 5 and the second filtering channel 6 and between the second filtering channel 6 and the third filtering channel 7; filter elements 9 are arranged in the first filtering channel 5, the second filtering channel 6, and the third filtering channel 7.

[0019] During use, water flows into the input connector 2 through a chiller. The input connector 2 divides the water flow through the first connecting channel pipe 19, the second connecting channel pipe 20, and the third connecting channel pipe 21, and then respectively conveys it to the first filtering channel 5, the second filtering channel 6, and the third filtering channel 7 in the three-channel filtering device 3 for separate filtering work. In this way, the efficiency of water filtration is greatly improved.

[0020] Among them, connection rings 10 are respectively arranged at both ends of the first filtering channel 5, the second filtering channel 6, and the third filtering channel 7. A sealing gasket 11 is arranged at the outer end of the connection ring 10. The sealing gasket 11 is integrally in a ring structure and is made of rubber material. The sealing gasket 11 is arranged between the connection ring 10 and the input connector 2 or the output connector 4. The setting of the sealing gasket 11 can increase the sealing performance of the connection part after the connection ring 10 is connected with the input connector 2 or the output connector 4.

[0021] Among them, the filter element 9 includes a filter housing 12, a primary filter plate 13, a secondary filter plate 14, and a tertiary filter plate 15. The filter housing 12 is in a cylindrical structure and has a through structure inside. The primary filter plate 13, the secondary filter plate 14, and the tertiary filter plate 15 are sequentially installed in the filter housing 12. The primary filter plate 13 is arranged at one end close to the input connector 2, and the tertiary filter plate 15 is arranged at one end close to the output connector 4. The primary filter holes 16 are evenly formed on the surface of the primary filter plate 13, and the primary filter holes 16 are in a cross shape. The secondary filter holes 17 are evenly formed on the surface of the secondary filter plate 14, and the secondary filter holes 17 are in a square shape. The tertiary filter holes 18 are evenly formed on the surface of the tertiary filter plate 15, and the tertiary filter holes 18 are in a conical shape.

[0022] When water enters the filter element 9, the water will sequentially pass through the primary filter plate 13, the secondary filter plate 14, and the tertiary filter plate 15 in the filter housing 12. The primary filter plate 13 blocks and filters large impurities. The cross shape of the primary filter holes 16 is to prevent the filter holes from being blocked by impurities. The square secondary filter holes 17 on the surface of the secondary filter plate 14 can block and filter medium-sized impurities. The funnel-shaped tertiary filter holes 18 on the surface of the tertiary filter plate 15 can facilitate the blocking and filtering of smaller impurities.

[0023] Among them, a first connection channel pipe 19, a second connection channel pipe 20, and a third connection channel pipe 21 are respectively arranged at one end of the input connector 2 and the output connector 4. The first connection channel pipe 19, the second connection channel pipe 20, and the third connection channel pipe 21 are respectively docked with the first filtering channel 5, the second filtering channel 6, and the third filtering channel 7. A total channel pipe 22 is arranged at the other end of the input connector 2 and the output connector 4. The first connection channel pipe 19, the second connection channel pipe 20, and the third connection channel pipe 21 in the input connector 2 and the output connector 4 are used to be respectively connected with the first filtering channel 5, the second filtering channel 6, and the third filtering channel 7, so as to further facilitate the input and output of water. The total channel pipe 22 in the input connector 2 is used to facilitate the input of water, and the total channel pipe 22 of the output connector 4 is used to facilitate the output of water.

[0024] The working principle and usage process of the present utility model:

[0025] During operation, water flows into the input connector 2 through the chiller. The input connector 2 divides the water flow through the first connecting channel pipe 19, the second connecting channel pipe 20, and the third connecting channel pipe 21, and then delivers the water to the first filtering channel 5, the second filtering channel 6, and the third filtering channel 7 in the triple-filtering device 3 for separate filtering operations. The water enters the filter element 9, and successively passes through the filter housing 12, the first-stage filter plate 13, the second-stage filter plate 14, and the third-stage filter plate 15. The first-stage filter plate 13 blocks and filters large impurities. The cross-shaped first-stage filter holes 16 are designed to prevent clogging of the filter holes by impurities. The square second-stage filter holes 17 on the surface of the second-stage filter plate 14 can block and filter medium-sized impurities. The funnel-shaped third-stage filter holes 18 on the surface of the third-stage filter plate 15 are convenient for blocking and filtering smaller impurities. After the filtering is completed, the water flows out through the output connector 4 and is further delivered to the cold water pool for use.
