DETAILED DESCRIPTION

[0023] Embodiment 1

[0024] like Figure 1-Figure 5 As shown, an integrated sewage treatment device proposed in this embodiment includes a pipe body, a water treatment agent box 10, a linkage valve assembly and an interception and cleaning assembly.

[0025] The pipe body includes an inlet pipe 1, an outlet pipe 9, a diverter pipe 2 connected to the inlet pipe 1 in the middle, a confluence pipe 8 connected to the outlet pipe 9 in the middle, and two groups of connecting pipe groups respectively connected between one end of the diverter pipe 2 and one end of the confluence pipe 8, that is, one group of connecting pipe groups has two ends connected to one end of the diverter pipe 2 and one end of the confluence pipe 8, and the other group of connecting pipes has two ends connected to the other end of the diverter pipe 2 and the other end of the confluence pipe 8.

[0026] like Figure 1 and Figure 2 As shown, the connecting pipe group includes a first ball tube 3, a cleaning pipe 4, a first connecting pipe 5, a second ball tube 6 and a second connecting pipe 7 which are connected in sequence. The first ball tube 3 is connected to the diverter pipe 2, and the second connecting pipe 7 is connected to the confluence pipe 8.

[0027] like Figure 1 and Figure 2 As shown, the diverter pipe 2 and the converging pipe 8 are both semicircular tubular structures. The sewage can be diverted from the middle of the diverter pipe 2 and can also be converged to the middle where it is connected to the outlet pipe 9 through the two ends of the converging pipe 8.

[0028] like Figure 2 As shown, the first connecting tube 5 and the second bulb tube 6 as well as the second bulb tube 6 and the second connecting tube 7 form a Venturi tube structure, and when sewage flows to these two areas, the flow rate can be increased. When water flows from the second bulb tube 6 to the intercepting and cleaning component, the backwashing effect is good.

[0029] like Figure 1 As shown, the water treatment agent box 10 is filled with liquid water treatment agent, which is connected to the top of the water inlet pipe 1, and a first control valve 11 is provided at the bottom. The water treatment agent box 10 contains liquid water treatment agent, and by opening the first control valve 11, the water treatment agent can be added to the water inlet pipe 1 and mixed with the textile wastewater. As the wastewater circulates, the fluff in the wastewater can be flocculated, which is convenient for subsequent interception and filtration.

[0030] The linkage valve assembly is used to switch the passages at both ends of the shunt pipe 2 to opposite opening and closing states, that is, when the passage at one end of the shunt pipe 2 is opened, the other end is closed.

[0031] There are two groups of interception and cleaning components, which are respectively located at the two connecting pipe groups, including a sewage pipe 33 connected to the bottom of the connecting pipe group, a filter component that is obliquely distributed and rotatably arranged on the inner wall of the connecting pipe group, a second valve plate 38 located at the rear side of the filter component, and a driving device arranged on the connecting pipe group. The driving device drives the filter component to rotate, and drives the second valve plate 38 to intermittently block or conduct the connecting pipe group. The front end of the projection contour of the filter component is flush with the rear end of the sewage pipe 33. When the filter component collects fluffy dirt, the bottom end is at the rear side of the sewage flow direction, and the top end is at the front side of the sewage flow direction, which is convenient for collecting fluffy dirt at the bottom of the inner side of the cleaning pipe 4 below the filter component. When the filter component rotates, it can push the dirt into the sewage pipe 33 through its own structure. At this time, the first valve plate 12 corresponding to the connecting pipe group here is adjusted to a vertical closed state in advance.

[0032] The second valve plate 38 intermittently blocks or conducts the connecting pipe group. When blocking, the fluff dirt is pushed down by the rotation of the filter assembly itself. When conducting, the sewage flowing in the other connecting pipe group is filtered by the inner filter assembly and the clean water obtained will flow backward to the manifold 8. Part of the clean water flows out through the outlet pipe 9, and the other part of the clean water flows back through the manifold 8 to the second connecting pipe 7, the second bulb 6, the first connecting pipe 5 and the cleaning pipe 4, and reversely flushes the fluff dirt on the front side of the filter assembly, thereby improving the cleaning effect and extending the service life of the filter assembly.

[0033] A second control valve 331 is provided at the lower part of the sewage pipe 33. When the second control valve 331 is opened, fluff and sewage can be discharged. Figure 5 As shown, a plurality of sewage guide plates 34 are staggeredly arranged up and down on both sides of the inner wall of the sewage guide pipe 33. The sewage guide plates 34 are distributed obliquely downward, so that the sewage is not easy to flow upward into the cleaning pipe 4.

[0034] This embodiment uses a liquid water treatment agent to flocculate the fluff, and cleans the fluff by rotation and backwashing, thereby achieving multi-stage sewage treatment. One of the two connecting pipe groups is selected for sewage treatment. When the filter assembly in one connecting pipe group needs to clean the fluff, the first valve plate 12 corresponding to the connecting pipe group is adjusted to a vertically closed state. At this time, the first valve plate 12 corresponding to the other connecting pipe group is in a horizontally open state, and normal sewage treatment can be performed. Textile sewage flows from the water inlet pipe 1 to the other end of the diversion pipe 2 and enters the other connecting pipe group. The fluff is filtered by the corresponding filter assembly on the inside. The filter assembly is tilted, and the second valve plate 38 on the rear side is in a horizontally open state.

Compared with the first embodiment, in the present embodiment, the linkage valve assembly includes two first valve plates 12 which are respectively rotatably arranged on the inner walls of the two first bulb tubes 3, a second rotating shaft 20 which is inclined at 45° to the horizontal plane and connected to the first valve plate 12, and a switching assembly for driving the two second rotating shafts 20 to rotate simultaneously, and the second rotating shaft 20 is rotatably arranged on the first bulb tube 3. The switching assembly includes two groups of linkage assemblies arranged side by side, a first housing 13 arranged on the connecting pipe group, a telescopic mechanism 14 arranged in the first housing 13, and a rack 15 connected to the end of the telescopic mechanism 14, and the telescopic mechanism 14 can adopt an electric push rod or a hydraulic cylinder or a cylinder. A slide rail can also be arranged in the first housing 13, and the rack 15 is slidably arranged on the slide rail to improve the stability of the horizontal sliding of the rack 15. The linkage assembly includes a first rotating shaft 17 rotatably arranged on the cleaning tube 4, a first gear 16 arranged on the first rotating shaft 17 and meshingly connected to the rack 15, a first bevel gear 18 arranged on the first rotating shaft 17, and a second bevel gear 19 connected to the outer end of the second rotating shaft 20. The second bevel gear 19 is meshingly connected to the first bevel gear 18. When one first valve plate 12 is in a horizontally open state, the other first valve plate 12 is in a vertically closed state.

[0037] In this embodiment, the telescopic mechanism 14 can drive the rack 15 to reciprocate, the rack 15 drives the two first gears 16 to rotate, the first gear 16 drives the first bevel gear 18 to rotate through the first rotating shaft 17, the first bevel gear 18 drives the second bevel gear 19 to rotate, and the second bevel gear 19 drives the first valve plate 12 to rotate through the second rotating shaft 20, so as to switch the first valve plate 12 between the horizontal state and the vertical state. When switching between these two states, the second rotating shaft 20 needs to be rotated 180°.

[0039] like Figure 1-Figure 5 As shown, the present embodiment proposes an integrated sewage treatment device. Compared with the first embodiment, in the present embodiment, the filter assembly includes a cylindrical filter frame 31 rotatably arranged on the inner wall of the cleaning tube 4 and a filter element 32 arranged inside the filter frame 31. The filter element 32 performs fluff filtering on the inside, and the filter frame 31 rotates on the outside. If the rotation speed of the filter frame 31 is increased, the centrifugal force can be used to assist in getting rid of the fluff on the filter element 32.

[0040] The second valve plate 38 is rotatably arranged on the inner wall of the second bulb 6, and the driving device includes a second housing 21 arranged on the cleaning tube 4, a motor 22 arranged in the second housing 21, a second gear 23 connected to the output end of the motor 22, a third shaft 25 rotatably arranged on the second housing 21, a third gear 24 arranged on the third shaft 25 and meshingly connected with the second gear 23, a third bevel gear 26 and a fifth bevel gear 35 respectively arranged at both ends of the third shaft 25, a mounting cover 29 penetrating the cleaning tube 4, a fourth shaft 28 rotatably arranged on the mounting cover 29, a fourth bevel gear 27 and a connecting frame 30 respectively arranged at both ends of the fourth shaft 28, a fifth shaft 37 rotatably arranged on the second bulb 6, and a sixth bevel gear 36 arranged at one end of the fifth shaft 37 and meshingly connected with the fifth bevel gear 35.

The second valve plate 38 is in a blocked state when it is vertically distributed, and is in a conducting state in other states. However, the conducting effect is best when the second valve plate 38 is horizontally distributed.

[0041] In this embodiment, the motor 22 can drive the second gear 23 to rotate, the second gear 23 drives the third rotating shaft 25 to rotate through the third gear 24, the third rotating shaft 25 drives the third bevel gear 26 and the fifth bevel gear 35 to rotate, the third bevel gear 26 drives the fourth bevel gear 27 to rotate, the fourth bevel gear 27 drives the filter assembly to rotate through the fourth rotating shaft 28 and the connecting frame 30, and the filter assembly is used to push and clean the fluff dirt.
