Specific embodiments

[0028] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] Refer to Figures 1 to 7As shown in the figure, the technical solution adopted in this specific embodiment is as follows: A rotary filter for sewage treatment, including a pool body 1, a rotating rod 2 rotatably arranged in the pool body 1 and horizontally arranged, a rotating motor 3 arranged between the rotating rod 2 and the side end face of the pool body 1 for driving the rotating rod 2 to rotate, a water inlet end 4 arranged at the right end of the pool body 1, a drainage end 5 arranged at the left end of the pool body 1, and a plurality of filter turntables horizontally and equidistantly arranged on the rotating rod 2. The filter turntable includes a plurality of turntable bodies 6 horizontally and equidistantly arranged on the rotating rod 2, a plurality of placement openings 7 annularly and equidistantly opened on each turntable body 6, a sliding frame plate 8 slidably arranged on the turntable body 6 and located in the placement openings 7, a filter element arranged in the sliding frame plate 8 for filtering impurities in the sewage, a plurality of fixed support plates 9 arranged on the peripheral side of the turntable body 6 and on both sides of each placement opening 7, a limiting plate 10 arranged at the upper end of the sliding frame plate 8 and above the fixed support plates 9, and a fixing member arranged between the limiting plate 10 and the fixed support plates 9 for fixing or releasing the fixing of the limiting plate 10 to the fixed support plates 9. Two fixed support plates 9 are symmetrically arranged on both sides of each placement opening 7 on the turntable body 6. There are a total of six placement openings 7, and the six placement openings 7 are annularly and equidistantly opened on the turntable body 6. The number of the sliding frame plates 8 corresponds to that of the placement openings 7.

[0030] The filter element includes a fixed frame 11 fixedly arranged on the sliding frame plate 8, a left mounting frame 12 and a right mounting frame 13 arranged on the sliding frame plate 8 and respectively located on the left and right sides of the fixed frame 11, a primary filter layer 14 arranged on the right mounting frame 13 for filtering particulate impurities, a secondary filter layer 14 arranged on the fixed frame 11 for reducing the color and odor in the sewage after the sewage passes through the particulate filter layer, and a tertiary filter layer 16 arranged on the left mounting frame 12 for reducing the metal substances in the sewage after the sewage passes through the secondary filter layer 14.

[0031] The left mounting frame 12 and the right mounting frame 13 are respectively in clearance fit with the sliding frame plate 8. Clamping protrusions 17 are respectively arranged on the upper and lower end faces of the left mounting frame 12 and the right mounting frame 13. Clamping grooves 18 are respectively opened on the sliding frame plate 8 on the left and right sides of the fixed frame 11. The number of the clamping protrusions 17 corresponds to that of the clamping grooves 18, and the clamping protrusions 17 and the clamping grooves 18 are in clamping fit.

[0032] The primary filter layer 14 is a grille membrane layer. The grille membrane is a structure similar to a grid, usually made of aluminum alloy or plastic. Its characteristic is that the pore size is relatively large, which is more suitable for filtering large-particle pollutants and cannot filter tiny particles and microorganisms such as bacteria. However, for some pollutants such as large particles or excess solid impurities, the filtering effect of the grille membrane is relatively good.

[0033] The secondary filtration layer 14 is an activated carbon filter element layer. The activated carbon filter element is mainly used to remove the color, odor, and residual chlorine in water, and can change the taste of water. It can be a granular filter element or a compressed activated carbon filter element, and the latter is usually used for the secondary filtration of household water purification equipment.

[0034] The tertiary filtration layer 16 is a ceramic filter element layer or a resin filter element layer. The ceramic filter element is mainly used for filtering, antibacterial, and activation treatment of drinking water, and can effectively remove harmful substances in water, including residual chlorine, suspended pollutants, organic chemicals, color and odor, and soluble heavy metal ions. The resin filter element is mainly used for softening water quality. By the principle of ion exchange, it adsorbs calcium and magnesium ions in water, thereby reducing the hardness of water and improving the usage experience.

[0035] Extension plates 19 are respectively arranged on the left end face of the left mounting frame 12 and the right end face of the right mounting frame 13.

[0036] The fixing member includes mounting openings 20 respectively opened on the upper end face of the fixing support plate 9, fitting clamping rods 21 respectively arranged on the lower end face of the limiting plate 10 and in clearance fit with the mounting openings 20, side end openings 22 opened on the side end face of the fixing support plate 9 and communicating with the mounting openings 20, corresponding card slots 23 opened on the side end face of the fitting clamping rod 21 for corresponding to the side end openings 22 after the fitting clamping rod 21 and the mounting openings 20 are fitted, and fixing bolts 24 threadedly connected to the fixing support plate 9 and located in the side end openings 22. The screw part of the fixing bolt 24 is engaged with the corresponding card slot 23. When it is necessary to fix the limiting plate 10 to the upper end of the fixing support plate 9, align the fitting clamping rod 21 with the mounting opening 20 and insert it. After the fitting clamping rod 21 and the mounting opening 20 are completely fitted, the positions of the corresponding card slot 23 and the side end opening 22 correspond. At this time, screw the fixing bolt 24 into the fitting clamping rod 21 until the screw part of the fixing bolt 24 is stuck in the corresponding card slot 23, so as to limit the lifting position of the fitting clamping rod 21 in the mounting opening 20, and fix the limiting plate 10 to the upper end of the fixing support plate 9.

[0037] A pulling handle 25 is arranged on the upper end face of the limiting plate 10.

[0038] Working principle of the present utility model: When it is necessary to remove the turntable from the rotating rod 2 for cleaning, push the turntable body 6 or drive the rotating rod 2 to rotate through the rotating motor 3 until the top of the sliding frame plate 8 to be removed faces directly upward. At this time, release the fixing of the limiting plate 10 on the fixing support plate 9 through the fixing member, and pull the sliding frame plate 8 upward so that it rises in the placement opening 7 until the sliding frame plate 8 is taken out from the placement opening 7, then the filter element on the sliding frame plate 8 can be cleaned. The part to be cleaned can be taken out separately according to customer needs, which can improve the cleaning efficiency of the turntable;

[0039] When sewage is discharged from the water inlet end 4 into the pool body 1, the rotating motor 3 drives the rotating rod 2 to rotate, thereby driving each turntable body 6 to rotate in the pool body 1. The water flow passes through the primary filter layer 14, secondary filter layer 15, and tertiary filter layer 16 in the sliding frame plate 8, and the sewage is filtered through the primary filter layer 14, secondary filter layer 15, and tertiary filter layer 16. After the sewage is filtered multiple times, it flows out from the drainage end 5;

[0040] When the sliding frame plate 8 is removed from the turntable body 6, the left mounting frame 12 and the right mounting frame 13 can be pulled outwards to be removed from the sliding frame plate 8, so as to facilitate the cleaning of each filter layer. When it is necessary to install the left mounting frame 12 and the right mounting frame 13, the left mounting frame 12 and the right mounting frame 13 are respectively pushed from the left side and the right side of the sliding frame plate 8 until the engaging protrusion 17 and the engaging groove 18 are engaged and connected, so as to form a resistance to the lateral movement of the left mounting frame 12 and the right mounting frame 13, and fix the two on the sliding frame plate 8;

[0041] The extension plate 19 can facilitate the hand to directly apply force to the left mounting frame 12 and the right mounting frame 13, so as to facilitate the removal of the left mounting frame 12 and the right mounting frame 13 from the sliding frame;

[0042] Pulling the handle 25 can facilitate the hand to directly pull the limiting plate 10 upward.
