[0041] like Figures 1 to 10 As shown, this embodiment provides an assembled precision filter, which is used in the field of resource and environmental technology and is suitable for precise deep treatment of effluent to ensure the quality of effluent. This assembled precision filter is a device used for deep treatment of effluent from sewage treatment plants. For example, it can reduce the suspended solid content in drainage water from 20 mg / L to below 10 mg / L, and the total phosphorus content from 1 mg / L to below 0.5 mg / L, ensuring that the effluent quality meets the Class A standard in these two aspects. This embodiment upgrades the precision filter to an assembled structure, adopts a segmented design, and provides a richer range of parameter specifications. Sewage treatment plants can assemble equipment in an individualized manner according to the processing volume requirements, so that the equipment performance is closer to the use requirements. At the same time, parts can be prefabricated in batches, shortening the product manufacturing cycle, reducing storage costs and transportation costs, and improving product competitiveness.

[0042] Specifically, the assembled precision filter mainly includes an inlet end plate 10, an outlet end plate 20, a fluid trough body 30, a drive device 40 and a filter drum 50. Among them, the inlet end plate 10 and the outlet end plate 20 are respectively arranged at both ends of the length direction of the fluid trough body 30, and the inlet end plate 10 and the outlet end plate 20 are used to close the fluid trough body 30. The filter drum 50 is rotatably arranged in the fluid trough body 30 with the length direction of the fluid trough body 30 as the axial direction. The filter drum 50 is used to filter suspended solids in sewage. During the filtering or cleaning process, the filter drum 50 can be rotated so that each position on the circumference of the filter drum 50 can evenly participate in the filtration or cleaning. The drive device 40 is connected to the filter drum 50, and the drive device 40 is used to drive the filter drum 50 to rotate. The fluid trough body 30 includes a trough body assembled by a plurality of trough modules 31 arranged along the length direction of the fluid trough body 30. Different numbers of trough modules 31 can be connected according to actual needs to obtain the required length of the fluid trough body 30. The filter drum 50 includes a drum body assembled from a plurality of drum modules 51 arranged along the length direction of the fluid tank body 30 . Different numbers of drum modules 51 can be connected according to actual needs to obtain the required length of the filter drum 50 .

[0043] The assembled precision filter of this embodiment divides the fluid trough body 30 and the filter drum 50 into multiple sections, which can be assembled using different numbers of modules according to actual needs to meet different processing requirements. In addition, each section can be standardized and serialized, and prefabricated in batches, which shortens the product manufacturing cycle, reduces storage and transportation costs, and improves product competitiveness. When the assembled precision filter of this embodiment is working, sewage enters the fluid trough body 30 from the water inlet end plate 10, is filtered by the filter drum 50, and is then discharged through the water outlet end plate 20. During the filtering or cleaning process of the filter drum 50, the drive device 40 drives the filter drum 50 to rotate.

[0044] In some examples, the assembled precision filter also includes a backwash system 60, which is used to clean the filter drum 50 in the opposite direction of the sewage flow during filtration. Backwashing can be performed simultaneously with filtration or in steps. The backwash system 60 includes a backwash pipe group 61, a slag receiving tank 62 and a backwash water inlet device 63. The backwash pipe group 61 is provided on the outside of the filter drum 50 and is used to flush water from the outside to the inside of the filter drum 50 so that the solid slag attached to the inside of the filter drum 50 can be separated from the filter drum 50. The slag receiving tank 62 is provided on the inside of the filter drum 50 and is used to receive the solid slag separated from the filter drum 50. The slag receiving tank 62 extends to the outside of the fluid tank body 30 and discharges the solid slag on the outside of the fluid tank body 30. The water outlet end of the backwash pipe group 61 faces the slag receiving tank 62, and the slag receiving tank 62 can receive the solid slag flushed out by the backwash pipe group 61. The backwash water inlet device 63 is arranged on the outside of the fluid tank body 30. The backwash water inlet device 63 can be easily installed on the outside of the fluid tank body 30, avoiding the complex structure inside the fluid tank body 30 and the inconvenience of installation. It is also beneficial to the power connection and maintenance of the backwash water inlet device 63. The outlet of the backwash water inlet device 63 is connected to the backwash pipe group 61, thereby supplying water to the backwash pipe group 61.

[0045] In some examples, the slag receiving trough 62 is detachably connected to the water inlet end plate 10, the water outlet end plate 20 or the fluid trough body 30, which facilitates the transportation, storage and installation of the slag receiving trough 62. The backwash pipe group 61 is detachably connected to the water inlet end plate 10, the water outlet end plate 20 or the fluid trough body 30, which facilitates the transportation, storage and installation of the backwash pipe group 61. The backwash water inlet device 63 is detachably connected to the backwash pipe group 61, which facilitates the transportation, storage and installation of both. For example, the backwash water inlet device 63 is detachably connected to the backwash pipe group 61 through a hose 64, and the backwash water inlet device 63 can be placed in a suitable position according to the actual installation environment, with high installation flexibility. Each component is detachable and standardized in design, has high interchangeability, can be positioned and connected on site, and is simple and practical.

[0046] In some examples, the inlet of the backwash water inlet device 63 is detachably connected to the bottom end of the fluid tank body 30 through a hose 64. The backwash water inlet device 63 receives a portion of the filtered water from the bottom end of the fluid tank body 30 and uses it for backwashing, which can save water resources.

[0047] In some examples, the backwash tube assembly 61 includes a tube body assembled from multiple tube modules arranged along the length direction of the fluid tank body 30 . The backwash tube assembly 61 can be assembled into a suitable length according to actual needs to better cooperate with the filter drum 50 .

[0048] In some examples, the slag trough 62 extends to the outside of one of the inlet end plate 10 and the outlet end plate 20. The end of the slag trough 62 has an inclined slag discharge port 65. The slag discharge port 65 can avoid the port 12 of the inlet end plate 10 or the outlet end plate 20 to avoid interference. In some examples, the drive device 40 includes a power input mechanism 41 disposed on the outside of the other of the inlet end plate 10 and the outlet end plate 20. The power input mechanism 41 and the slag discharge port 65 are separately provided, which makes the component layout more reasonable and helps to reduce the size of the assembled precision filter.

[0049] In some examples, the backwash pipe group 61 is arranged above the filter drum 50. When sewage is filtered, the sewage will gather below under the action of gravity. The backwash pipe group 61 is arranged above to facilitate the separation of backwashing and filtration.

[0050] In some examples, the slag receiving trough 62 opens upward and has an inverted trapezoidal cross-section to facilitate slag receiving.

[0051] In some examples, the drive device 40 includes a power input mechanism 41, a rotating shaft 42, a driving wheel 43, and a driven wheel 44. The power input mechanism 41 is detachably connected to the outside of the inlet end plate 10 or the outlet end plate 20 for ease of assembly. The power input mechanism 41 is connected to the rotating shaft 42. The driving wheel 43 and the driven wheel 44 are located within the fluid tank body 30. The rotating shaft 42 is connected to the driving wheel 43, which meshes with the driven wheel 44. The driven wheel 44 is connected to the filter drum 50. The gear transmission method is efficient, stable, and easy to repair and maintain.

[0052] In some examples, all tank modules 31 and all drum modules 51 are identical, facilitating standardized module manufacturing. The filter drum 50 further includes a first connector 52 and a second connector 53, respectively, disposed at either end of the filter drum 50. The first connector 52 is located near the inlet end plate 10 and extends toward the water inlet of the inlet end plate 10, thereby extending the filtration area and guiding the wastewater. The second connector 53 is located near the outlet end plate 20 and is equipped with a filter screen to prevent unfiltered wastewater from being discharged directly from the end of the filter drum 50.

[0053] In other examples, at least two trough modules 31 are different, and at least two drum modules 51 are different. Standardized modules with different parameters can be manufactured, and by selecting modules with different size parameters for assembly, it can be more flexibly adapted to different sewage treatment needs. Different modules can be designed at the water inlet and outlet to meet different filtration requirements at the water inlet and outlet. For example, the drum module 51 includes a first drum module 51 disposed near the water inlet end plate 10 and a second drum module 51 disposed near the water outlet end plate 20. The end of the first drum module 51 extends toward the water inlet of the water inlet end plate 10, and the end of the second drum module 51 is provided with a filter.

[0054] In some examples, the filter drum 50 is hollow and, aside from the slag trough 62, contains no other components, such as a rotating shaft, thereby reducing resistance to the wastewater. Both ends of the filter drum 50 are rotatably connected to the inlet end plate 10, the outlet end plate 20, or the fluid tank body 30, for example, via bearings.

[0055] In some examples, the fluid tank body 30 further includes a reinforcing rib 32 . The reinforcing rib 32 is disposed at the bottom end of the fluid tank body 30 , thereby increasing the strength of the fluid tank body 30 .

[0056] In some examples, the assembled precision filter further includes a movable cover 70 movably connected to the top of the fluid tank body 30 . The movable cover 70 allows the fluid tank body 30 to be easily opened, thereby facilitating repair and cleaning.

[0057] In some examples, the movable cover 70 is assembled from multiple sections of cover modules arranged along the length direction of the fluid tank body 30 , and can be assembled into a suitable length according to actual needs to facilitate cooperation with the fluid tank body 30 .

[0058] In some examples, a first positioning structure 33 is provided on the top of the fluid tank body 30 , and a second positioning structure is provided on the movable cover plate 70 .
