[0025] It needs to be explained that, due to the problems of traditional sand filter wall, such as difficulty in replacing filter material, easy to be blocked and inconvenient to clean, etc., limiting its application effect and service life, the detachable design of the scheme not only significantly improves the maintenance convenience of the equipment and reduces the maintenance cost, but also ensures the regular replacement of the filter wall body 6 and its filter material; this design enables the operator to easily plug, clean and replace the filter wall body 6 and its components, thereby maintaining the filtering efficiency and performance of the equipment and prolonging the service life of the equipment; at the same time, the filtering function of the filter wall body 6 effectively removes suspended solids, organic matter and other impurities in the water, significantly improving the water quality; this efficient purification process not only meets the water quality requirements of rainwater after filtration for reuse or subsequent system water inlet, but also provides safe and reliable protection for production, life and environmental water.

[0026] Specifically, in the present embodiment, the scheme mainly includes a sedimentation tank 1; first, the water to be treated enters the pre-filtering pool 2 part of the sedimentation tank 1 through a specific channel; in the pre-filtering pool 2, the larger particles and impurities in the water will naturally settle due to gravity, preliminarily purifying the water quality; then, the water after preliminary sedimentation flows through the water treatment assembly installed in the sedimentation tank 1; the water treatment assembly includes a mounting bracket 4, which is internally separated into multiple independent installation cavities by a side plate 5; each installation cavity is installed with a filter wall body 6, and these filter wall bodies 6 are the key to further purifying water quality;

[0027] The side wall of the filter wall body 6 is provided with a limiting strip 8 matched with the limiting groove 7 of the lower side wall of the installation cavity; this clamping design not only ensures the stability of the filter wall body 6 in the installation cavity, but also enables the filter wall body 6 to be easily plugged and unplugged, facilitating subsequent offline cleaning or replacement; when the water flow passes through the filter wall body 6, the filter material inside the filter wall body 6 effectively removes suspended solids, organic matter and other impurities in the water, further improving the water quality;

[0028] Above the filter wall body 6, assembly grooves 9 are formed in the upper side walls of the mounting bracket 4 and the side plate 5; a connecting spring 10 and a damper are arranged in the assembly groove 9, and they jointly act on a feeding plate 11; when the water flow exerts pressure on the filter wall body 6, the feeding plate 11 will be adjusted slightly under the buffering action of the connecting spring 10 and the damper, ensuring that the filter wall body 6 always maintains in the best working state, while reducing the vibration and noise caused by water flow impact.

[0029] As shown in the further preferred embodiment of the utility model, Figure 4 The upper end side of the filter wall body 6 is provided with an open end; an end cover 12 is arranged at the open end, a plurality of threaded holes 13 are formed in the four corner positions of the end cover 12 opposite to the filter wall body 6, and a same fastening bolt 14 is threadedly matched in the corresponding two threaded holes 13.

[0030] In the embodiment, when the operator places the end cover 12 at the opening of the filter wall body 6, they can firmly fix the end cover 12 on the filter wall body 6 by rotating the fastening bolts 14 into the corresponding threaded holes 13; this fastening mode is not only simple and effective, but also can ensure the close connection between the end cover 12 and the filter wall body 6, preventing the filter material from leaking from the opening under the impact of the water flow; at the same time, since the fastening bolts 14 are located at the four corner positions, they can also provide uniform support force for the end cover 12, keeping the end cover 12 stable and firm.

[0031] When the filter wall body 6 needs to be cleaned or the filter material needs to be replaced, the operator can easily unscrew the fastening bolts 14, remove the end cover 12, and then perform the corresponding operation; this detachable design greatly improves the maintenance convenience of the equipment, enabling the operator to easily complete the cleaning of the filter wall body 6 and the replacement of the filter material.

[0032] In further preferred embodiments of the utility model, as shown in Figure 4 The filter wall body 6 is provided with a filter cavity, and the filter cavity is filled with filter material.

[0033] In the embodiment, when the water flow to be treated passes through the filter wall body 6, the water flow enters the filter cavity and fully contacts the filter material; in this process, the filter material adsorbs impurities in the water and fixes them on the surface or inside of the filter material; as the water flow continues to wash, the filter material gradually saturates, at which time the filter wall body 6 can be taken out of the water treatment system for cleaning or replacement by offline cleaning, thereby restoring its filtering capacity.

[0034] In further preferred embodiments of the utility model, as shown in Figure 4 The side wall of the filter wall body 6 is provided with a plurality of filter holes 15, and the inner diameter size of the filter holes 15 is smaller than the particle size of the filter material.

[0035] In the embodiment, it is ensured that the water flow can smoothly pass through the filter material layer when penetrating the filter wall body 6, and the filter material itself cannot flow out due to its excessive size, which not only maintains the structural integrity of the filter wall body 6, but also greatly improves the filtering efficiency.

[0036] In further preferred embodiments of the utility model, as shown in Figure 1 The sedimentation tank 1 is provided with a water inlet channel 16 adjacent to one side of the pre-filtering tank 2.

[0037] In the embodiment, the main function of the water inlet channel 16 is to introduce the water flow to be treated into the pre-filtering tank 2 part of the sedimentation tank 1.

[0038] In further preferred embodiments of the utility model, as shown in Figure 1As shown, the sedimentation tank 1 is adjacent to one side of the post-filter tank 3, and a drainage channel 17 is provided in the post-filter tank 3.

[0039] In this embodiment, the main function of the drainage channel 17 is to guide the filtered water from the post-filter tank 3 to the subsequent water treatment process or directly to the use point.

[0040] In further preferred embodiments of the present application, as shown in Figure 4 A bottom groove 18 is provided at the bottom of the mounting cavity.

[0041] In this embodiment, the bottom groove 18 and the filter wall body 6 improve the stability and durability of the equipment, as the filter wall body 6 can be firmly installed on the bottom groove 18 during installation, so it can better withstand the impact and vibration of the water flow, thereby prolonging the service life of the equipment.

[0042] In further preferred embodiments of the present application, as shown in Figure 4 The inner diameter of the bottom groove 18 is adapted to the outer diameter of the filter wall body 6.

[0043] In this embodiment, not only the stable installation and sealing performance of the equipment are ensured, but also the stability and durability of the equipment are improved, providing a strong guarantee for the continuous and efficient operation of the water treatment system.

[0044] Working principle: when the device is in use, the water to be treated first enters the pre-filter tank 2 of the sedimentation tank 1 through the water inlet channel 16; in the pre-filter tank 2, the wastewater to be treated flows through the water treatment assembly installed in the sedimentation tank 1; the water treatment assembly includes a mounting bracket 4, which is ingeniously divided into multiple independent mounting cavities by a side plate 5; a filter wall body 6 is installed in each mounting cavity, and these filter wall bodies 6 are responsible for water purification;

[0045] A limiting strip 8 is provided on the side wall of the filter wall body 6, which matches the limiting groove 7 of the lower side wall of the mounting cavity; this clamping design not only ensures the stability of the filter wall body 6 in the mounting cavity, but also gives the filter wall body 6 the flexibility of easy plugging and unplugging, providing great convenience for subsequent offline cleaning or replacement;

[0046] When the water flow passes through the filter wall body 6, it will enter the filter cavity provided in the interior of the filter wall body 6; here, the filter material will fully contact with the water flow and exert its strong adsorption capacity, effectively removing suspended solids, organic matter and other impurities in the water, so as to significantly improve the water quality;

[0047] In order to ensure that the filter wall body 6 is always kept in the best working condition, the assembly groove 9 is arranged on the upper side wall of the installation support 4 and the side plate 5, the connecting spring 10 and the damper are arranged in the assembly groove 9, and the connecting spring 10 and the damper jointly act on the feeding plate 11; when the water flow generates pressure on the filter wall body 6, the feeding plate 11 is finely adjusted under the buffering action of the connecting spring 10 and the damper, so that the vibration and noise generated by the water flow impact are effectively reduced;

[0048] The stability and durability of the equipment are further improved by the adaptability design of the bottom groove 18 and the filter wall body 6; the filter wall body 6 can be firmly installed on the bottom groove 18 during installation, so that the impact and vibration of the water flow can be better resisted, thereby prolonging the service life of the equipment;

[0049] When the operator needs to clean or replace the filter material of the filter wall body 6, the filter wall body 6 can be taken out from the installation cavity, then the fastening bolts 14 located at four corner positions of the filter wall body 6 are unscrewed, the end cover 12 is removed, and the corresponding operation is performed; the detachable design greatly improves the maintenance convenience of the equipment;

[0050] The clean water filtered by the filter wall body 6 is finally smoothly guided out of the post-filtering pool 3 through the drainage channel 17 and flows into the subsequent water treatment link or is directly discharged to the use point; the processing flow ensures the continuous purification and efficient utilization of the water quality.
