[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] The modular filter box of the utility model is as follows: Figure 1 , Figure 2 and Figure 3 As shown, it includes a rectangular box body 1, wherein the box body 1 has a filter cavity inside, and an openable and closable top cover 8 is arranged on the top of the filter cavity, and the filter cavity is divided into a plurality of filling cavities by a horizontal partition 2, and a filter filler 3 is arranged in each filling cavity, and the particle size of the filter filler 3 decreases from bottom to top; a plurality of water holes are arranged on the top cover 8, the side plate, the bottom plate and the partition 2 of the box body 1, and the diameter of the water hole is smaller than the particle size of the filter filler 3; the outer walls of the two mutually parallel side plates of the box body 1 are respectively provided with vertical guide grooves 4 and guide convex plates 5, and the top surfaces of the other two side plates of the box body 1 are provided with positioning screw holes 6.

[0019] The housing 1 can be a metal housing, which is welded by metal plates and has high strength. The top cover 8 can close the upper port of the filter cavity to prevent the filter filler 3 from falling outside the housing 1, and can also open the filter cavity to add the filter filler 3 to the filter cavity or remove the filter filler 3 in the filter cavity. The top cover 8 can be connected to the side plate of the housing 1 by bolts, or one end of the top cover 8 is hinged to the housing 1, and the other end is connected to the housing 1 by a locking member, and the locking member can be a conventional buckle, lock, etc. The partition 2 is used to separate the filter fillers 3 of different particle sizes. By setting a plurality of filter fillers 3 of different particle sizes, water can be filtered in multiple stages to improve the filtering effect. Many evenly distributed water holes are set on the housing 1 and the partition 2 to ensure that water can quickly enter and exit the housing 1 and the filter filler 3. The guide groove 4, the guide convex plate 5 and the positioning screw hole 6 play a role in enhancing the stability of the modular filter box.

[0020] The modular filter box of the utility model can be produced, transported and installed separately. During installation, a horizontal support plate is first set in the water treatment, and a through hole is set on the support plate. The water in the treatment pool flows from bottom to top. The support plate can be a reinforced concrete plate. The modular filter box is placed on the support plate of the water treatment pool, and the support plate can support the box body 1. When installing the next modular filter box, align the guide convex plate 5 of the next modular filter box with the guide groove 4 of the previous modular filter box, and then lower the next modular filter box so that the guide convex plate 5 extends into the guide groove 4. Any two adjacent modular filter boxes are assisted in positioning by the guide convex plate 5 and the guide groove 4, so that each row of modular filter boxes becomes a whole and can stand stably on the support plate. The weight of a single modular filter box is relatively light and easy to operate. When it is necessary to replace or clean the filter filler 3, each modular filter box can be directly hoisted to the outside of the water treatment pool using a lifting device, and all the filter fillers 3 can be quickly taken out, and the construction efficiency is high.

[0021] The guide groove 4 can be in the shape of a rectangular groove, a semicircular groove, etc. Preferably, the guide groove 4 is two dovetail grooves, and the guide convex plate 5 is two dovetail-shaped convex plates. The dovetail groove has a better positioning effect and can prevent the guide convex plate 5 from escaping from the guide groove 4.

[0022] There are two, three, or four partitions 2, which are determined according to the filtering requirements. When there are two partitions 2, the filter cavity is divided into three filling cavities, each of which is filled with a filter filler 3. Specifically, the filter filler 3 includes pebble fillers, coarse sand fillers, and quartz sand fillers arranged in sequence from bottom to top. The pebble filler is filled in the bottom filling cavity, the coarse sand filler is filled in the middle filling cavity, and the quartz sand filler is filled in the top filling cavity. Water flows from bottom to top, and can perform multi-stage filtration on the water, fully removing solid impurities of various particle sizes in the water to ensure the filtering effect.

[0023] In order to facilitate the lifting of the modular filter box, a lifting ring 7 is provided on the top cover 8 , and the lifting ring 7 can be welded to the top cover 8 .

[0024] In order to facilitate the loading of the multi-stage filter filler 3 into the box body 1, the inner wall of the side plate of the box body 1 is provided with a vertical positioning boss 9, the edge of the partition 2 is provided with a notch, the positioning boss 9 is located in the notch and slides with the notch, and the edge of the partition 2 slides with the inner wall of the box body 1. Since the partition 2 slides with the inner wall of the box body 1, when loading the filter filler 3 into the box body 1, all the partitions 2 can be taken out first, and then a proper amount of large-particle filler is added to the box body 1, and then a partition 2 is loaded into the box body 1, and the partition 2 is positioned by the positioning boss to keep the partition 2 horizontal, and then the intermediate-particle filler is added to the box body 1, and the intermediate-particle filler uses its own gravity to press the partition 2, and then another partition 2 is loaded into the box body 1, and finally the small-particle filler is added and the top cover 8 is covered. Since the position of the partition 2 is not fixed at a certain height, the thickness of each filter filler 3 can be flexibly adjusted.

[0025] This paper uses a new type of multi-stage filtration component, such as Figure 4 As shown, including multiple rows Figures 1 to 3 In the modular filter box shown, in each row of modular filter boxes, the guide protrusion 5 of the box body 1 is inserted into the guide groove 4 of the adjacent box body 1; a connecting plate 10 is provided on the top of two adjacent rows of modular filter boxes, and a plurality of connecting bolts 11 with a clearance fit with the connecting plate 10 are provided on the connecting plate 10, and the connecting bolts 11 are threadedly connected to the positioning screw holes 6.

[0026] The size of each modular filter box is determined according to the area of ​​the water treatment tank to ensure that the length of each row of modular filter boxes is exactly the same as the length or width of the water treatment, and all modular filter boxes can just fill the water treatment tank. The connecting plate 10 is used to connect two adjacent rows of modular filter boxes into one, thereby improving the stability of the entire filter assembly. The connecting plate 10 is provided with a plurality of groups of through holes, and the connecting bolts 11 can pass through the through holes. After all the modular filter boxes are placed in the water treatment tank, the connecting plate 10 is then placed on the upper surface of the modular filter boxes, and it is ensured that the through holes on the connecting plate 10 are aligned with the positioning screw holes 6, and then the connecting bolts 11 are installed into the positioning screw holes 6.

[0027] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
