DETAILED DESCRIPTION

[0017] To make the purpose, technical scheme and advantage of the utility model embodiment more clear, the technical scheme in the utility model embodiment will be described clearly and completely below in combination with the embodiment of the utility model, obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor are within the scope of the utility model protection.

[0018] The following will be combined with the drawings Figures 1-5 The utility model will be described in further detail below in combination with the drawings and specific embodiments:

[0019] A pipeline sewage treatment device includes a main outlet pipe 6, a main inlet pipe 1, and a main discharge pipe 9 arranged horizontally from top to bottom. The middle sections of the main outlet pipe 6 and the main inlet pipe 1 are respectively horizontally connected to the main outlet pipe 7 and the main inlet pipe 2. The main inlet pipe 1 on both the left and right sides of the main inlet pipe 2 is equipped with an inlet electric valve 11. The lower side of the middle section of the main discharge pipe 9 is vertically connected to the main discharge pipe 9. The main discharge pipe 9 on both the left and right sides of the main discharge pipe 10 is equipped with a discharge electric valve 12. The main outlet pipe 7 is equipped with an outlet flow meter 13.

[0020] In this embodiment, preferably, the inlet electric valve 11, the drain electric valve 12, and the outlet flow meter 13 are all electrically connected to the controller. The controller is used to control the opening and closing of the inlet electric valve 11 and the drain electric valve 12 by the flow data detected by the outlet flow meter 13. The controller is a further application of prior art in this application, and its specific structure will not be described in detail.

[0021] Both sides of the main water inlet pipe 1 are provided with water distribution pipes 3 connected to it. A filter device 5 is provided on the upper side of the water distribution pipe 3. The upper and lower ends of the filter device 5 are connected to the main water outlet pipe 6 and the water distribution pipe 3 respectively. The filter device 5 includes a filter cylinder 51. The upper and lower ends of the filter cylinder 51 are connected to the main water outlet pipe 6 and the water distribution pipe 3 respectively through connecting flanges 4. The filter cylinder 51 is provided with a filter chamber 52 connected to the main water outlet pipe 6 and the water distribution pipe 3. A flexible filter screen 53 is provided in the middle of the filter chamber 52. The flexible filter screen 53 is detachably connected to the inner wall.

[0022] In this embodiment, preferably, the flexible filter screen 53 is a filter screen that can move flexibly up and down with the water flow. Its advantage is that the filtered deposits can be effectively detached and peeled off as the flexible filter screen 53 moves flexibly.

[0023] like Figure 4 As shown in the diagram, the arrows indicate the direction of water flow. Wastewater flows from below the filter chamber 52 upwards, and impurities and deposits in the wastewater are filtered out below the flexible filter screen 53. The water flowing through the flexible filter screen 53 becomes relatively clean water, and after passing through the main outlet pipe 6, it is discharged from the secondary outlet pipe 7.

[0024] A sludge storage device 8 is provided on the lower side of the water distribution pipe 3. The upper and lower ends of the sludge storage device 8 are respectively connected to the water distribution pipe 3 and the main sewage discharge pipe 9. The sludge storage device 8 includes a sludge storage cylinder 81. The upper and lower ends of the sludge storage cylinder 81 are respectively connected to the water distribution pipe 3 and the main sewage discharge pipe 9 through connecting flanges 4. The sludge storage cylinder 81 has a sludge storage cavity 82 that is connected to the water distribution pipe 3 and the main sewage discharge pipe 9.

[0025] In this embodiment, as Figure 5The arrow direction in the figure is the water flow direction. When the water flows in the opposite direction, i.e. the relatively clean water flows downward, the flexible filter screen 53 moves downward, and the dirt and attachments adhered to the flexible filter screen 53 can fall off in large quantities during the flexible movement from top to bottom, and enter the dirt storage cavity 82. At this time, the corresponding dirt discharge electric valve 12 has been opened, and the dirt and attachments together with the accumulated dirt in the dirt storage cavity 53 are discharged from the dirt discharge auxiliary pipe 10 along with the water flow through the dirt discharge main pipe 9.

[0026] Working principle:

[0027] (1) Water supply starts

[0028] At this time, the flexible filter screen 53 does not adhere to dirt and attachments. Both of the water inlet electric valves 11 are opened, and both of the dirt discharge electric valves 12 are closed. The water flows into the water inlet main pipe 1 through the water inlet auxiliary pipe 2, and then flows into the filter device 5 through two paths, i.e. left and right paths. After the dirt and attachments in the sewage are filtered by the flexible filter screen 53, the sewage becomes relatively clean water, which is discharged from the water outlet auxiliary pipe 7 through the water outlet main pipe 6.

[0029] (2) After running for a period of time,

[0030] When the water supply runs for a period of time, the dirt and attachments adhered to the flexible filter screen 53 increase, and the water flow decreases. When the water outlet flow meter 13 detects that the water outlet flow decreases to the set lower limit of the flow, the controller controls the two water inlet electric valves 11 and the two dirt discharge electric valves 12 to work according to the program setting:

[0031] ① The water inlet electric valve 11 on the left side of the water inlet main pipe 1 is closed, and at the same time, the dirt discharge electric valve 12 on the left side is opened. At this time, the water flow of the water inlet main pipe 1 can only pass through the right water distribution pipe 3 and the filter cavity 52. After passing through, part of the water flow continues to be discharged through the water outlet main pipe 6 and the water outlet auxiliary pipe 7, and the other part of the water flow flows reversely downward through the water outlet auxiliary pipe 7 and the water outlet main pipe 6 on the left side, and the water flow flows through the left filter cavity 52 to wash the left flexible filter screen 53, and the flexible filter screen 53 moves downward. During the flexible movement from top to bottom, the dirt and attachments adhered to the flexible filter screen 53 can fall off in large quantities, enter the dirt storage cavity 82, and then be discharged from the dirt discharge auxiliary pipe 10 through the dirt discharge main pipe 9.

[0032] ② Then the left water inlet electric valve 11 is opened, and at the same time, the left dirt discharge electric valve 12 is closed. The right water inlet electric valve 11 is closed, and at the same time, the right dirt discharge electric valve 12 is opened. Repeat step ① to wash the right flexible filter screen 53.

[0033] ③ After the washing is completed, both of the water inlet electric valves 11 are opened, and both of the dirt discharge electric valves 12 are closed, and the water flow through the flexible filter screen 53 increases, and the normal water discharge amount is restored or approaches.
