Referring to fig. 3 and 4, the filter assembly 4 includes a housing 41, a plurality of second partitions 42, and a plurality of filter members 43.

The casing 41 is a hollow rectangular parallelepiped structure, the casing 41 is mounted on one side of the casing 1 near the top, and the casing 41 and the mixing pipe 32 are located on the same side of the casing 1. In this embodiment, the housing 41 is preferably supported by a bracket to be mounted on the case 1, and the longitudinal direction of the housing 41 is preferably perpendicular to the longitudinal direction of the case 1 after the housing 41 is mounted.

The plurality of second partition plates 42 are installed inside the casing 41, and are separated inside the casing 41 to form a second flow passage 411 with an S-shaped track in the vertical direction, the top of the mixing pipeline 32 is externally connected with a pipeline fixedly connected with the casing 41 and communicated with the starting point position at the upstream of the second flow passage 411, the casing 41 is externally connected with a pipeline connected with the box body 1, and two ends of the pipeline are respectively communicated with the ending point position at the downstream of the second flow passage 411 and the starting point position at the upstream of the first flow passage 14.

In the process that the mixed solution flows upwards in the second flow passage 411, the difficulty of the suspended matters in the process that the suspended matters move along with the flow of the mixed solution is increased under the influence of the gravity of the suspended matters, so that the quantity of the suspended matters moving along with the flow passage of the mixed solution can be reduced; at the same time, the mixed solution flows downwards through the filter element 43, which can facilitate the filtration of the mixed solution through the filter element 43, and reduce the probability of the filtration process being affected due to too slow flow rate of the mixed solution through the filter element 43.

The filter 43 has a rectangular plate-like structure as a whole, and a plurality of filter holes 431 for the mixed solution to pass through are formed in the filter 43. In this embodiment, the filter 43 is preferably an activated carbon plate, and after the mixed solution contacts with the filter 43, the filter 43 can remove a part of free chlorine in the mixed solution, and can filter out suspended matters with a certain particle size, so that suspended matters and free chlorine in the mixed solution entering the disinfection tank 13 after passing through the filter assembly 4 are reduced, and further the disinfection effect of the subsequent mixed solution in the disinfection tank 13 can be improved.

The filter elements 43 are each mounted in a vertically downward flowing section of the second flow channel 411, i.e. the filter elements 43 are mounted between two second partition plates 42, when the number of second partition plates 42 is greater, the filter elements 43 will be distributed between different adjacent second partition plates 42. The plurality of filter elements 43 are equally spaced apart in the vertical direction, and in this embodiment, the filter assembly 4 preferably includes three filter elements 43; in other embodiments, the number of filter elements 43 may be greater as desired.

The rotation of the filter element 43 is limited, when the filter element 43 rotates to the limit position along the flow direction of the position of the second flow passage 411, the filter element 43 is in an inclined state, and a space exists between one end of the filter element 43 away from the rotation axis and the adjacent second partition plate 42; when the filter element 43 is rotated to the extreme position against the flow direction of the position thereof in the second flow passage 411, the filter element 43 is in a horizontal state at this time, and the end of the filter element 43 away from the own rotation axis is brought into contact with the adjacent second partition plate 42 at this time.

In this embodiment, the first elastic member 44 is preferably a torsion spring, and since the torsion spring is a conventional technology, only the installation position of the torsion spring is shown in the drawings, and the structure of the torsion spring is omitted from the description.

When the filter holes 431 on the filter element 43 are blocked by the suspended matter, the acting force of the mixed solution flow on the filter element 43 drives the filter element 43 to rotate against the acting force of the first elastic element 44, and the larger the number of the filter holes 431 blocked by the suspended matter is, the larger the rotating angle of the filter element 43 is. When the number of the filter holes 431 blocked by the suspended matters exceeds a certain number, the filter element 43 rotates to an inclined state with the maximum angle at the limit position, and at this time, the space between one end of the filter element 43 away from the rotation axis and the adjacent second partition plate 42 can be used for the suspended matters blocking the filter holes 431 of the filter element 43 to pass through.

Referring to fig. 4 and 6, further, the filter assembly 4 further includes a plurality of blocking members 45 and a plurality of second elastic members 46.

When the blocking member 45 slides to the limit position in a direction approaching the rotation axis of the corresponding filter member 43, the relief hole 452 is aligned with the corresponding filter hole 431. When the filter holes 431 on the filter 43 are blocked by the suspended matters, the suspended matters will also block the corresponding yielding holes 452; when the filter 43 rotates under the force of the mixed solution flowing, the force of the mixed solution flowing on the extension 451 drives the blocking member 45 to slide against the force of the second elastic members 46 during the process of flowing the mixed solution from the space between the filter 43 and the second partition 42; when the filter 43 is rotated to the limit position, the blocking remover 45 slides to the limit position in a direction away from the rotation axis of the corresponding filter 43, and the extension 451 comes into contact with the adjacent second partition 42.

After the blocking removing member 45 slides relative to the filtering member 43, the blocking removing member 45 will squeeze the suspended matters forming the blocking, so that the suspended matters leave from the openings at the two ends of the corresponding filtering holes 431, thereby realizing the blocking removing effect.
