Description

Technical Field

[0001] The present invention relates to the field of sewage treatment, and in particular to an integrated sewage treatment device. Background Art

[0002] During the production process of the textile industry, textile fabrics need to be cleaned, and the resulting textile wastewater will contain textile fluff impurities. During wastewater treatment, multiple filtration methods are needed to intercept and filter the textile fluff impurities contained in the textile wastewater.

[0003] Chinese Patent Publication No. CN115057555B discloses an integrated sewage treatment device, including a device body, wherein a textile fluff cleaning device is provided on one side of the interior of the device body. Through the provision of the textile fluff cleaning device, the barbs on the hollow through-hole hook licker-in roller will hook the fluff and fibers in the textile sewage during the rotation of the hollow through-hole hook licker-in roller, thereby avoiding the problem of impurities such as fluff and fibers clogging the filter screen, thereby improving the efficiency of textile sewage treatment. Through the provision of an anti-particulate water treatment agent precipitation device, a fork-shaped spring plate deforms and drives the mixed water treatment agent to flow toward the through-holes of the hollow through-hole hook licker-in roller, so that the suspended particulate water treatment agent can be evenly discharged from the through-holes of the hollow through-hole hook licker-in roller. When the fork-shaped spring plate deforms, it drives the flipping blade to swing and stir the mixed water treatment agent, thereby further avoiding the problem of precipitation of the particulate water treatment agent.

[0023] Example 1

[0024] like Figure 1-Figure 5 As shown, the integrated sewage treatment equipment 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 bulb tube 3, a cleaning pipe 4, a first connecting pipe 5, a second bulb tube 6 and a second connecting pipe 7 connected in sequence. The first bulb 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 confluence 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 connects with the outlet pipe 9 through both ends of the confluence pipe 8.

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

[0029] like Figure 1 As shown, a water treatment agent tank 10 is filled with liquid water treatment agent and connected to the top of the water inlet pipe 1. A first control valve 11 is provided at the bottom. The liquid water treatment agent in the water treatment agent tank 10 can be added to the water inlet pipe 1 by opening the first control valve 11. The water treatment agent mixes with the textile wastewater, and as the wastewater circulates, it flocculates the fluff in the wastewater, facilitating 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 open and closed states, that is, when the passage at one end of the shunt pipe 2 is open, the other end is closed.

[0031] There are two groups of intercepting and cleaning components, which are located at the two connecting pipe groups respectively, 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 on 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 projected outline of the filter component is flush with the rear end of the sewage pipe 33. When collecting fluffy dirt, the bottom end of the filter component 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 inside 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 opens the connecting pipe group. When blocked, the lint is pushed down only by the rotation of the filter assembly itself. When opened, the sewage flowing through the other connecting pipe group is filtered by the inner filter assembly, and the purified water is then transferred backward to the manifold 8. Some of this purified water flows out through the outlet pipe 9, while the remaining purified 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, flushing away the lint on the front side of the filter assembly, improving the cleaning effect and extending the service life of the filter assembly.

[0033] A second control valve 331 is provided at the lower portion of the sewage pipe 33. When the second control valve 331 is opened, fluff and dirt can be discharged. Figure 5 As shown, a plurality of sewage guide plates 34 are staggeredly arranged 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 fluff and removes the fluff through rotation and backwashing, 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 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, enabling normal sewage treatment. 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.

[0035] Example 2

[0036] like Figure 1-Figure 5As shown, this embodiment proposes an integrated sewage treatment equipment. Compared with the first embodiment, in this embodiment, the linkage valve assembly includes two first valve plates 12 that are rotatably arranged on the inner walls of the two first bulbs 3, a second rotating shaft 20 that is inclined at 45 degrees to the horizontal plane and connected to the first valve plates 12, and a switching assembly for driving the two second rotating shafts 20 to rotate simultaneously. The second rotating shaft 20 is rotatably arranged on the first bulb 3. The switching assembly includes two groups of linkage assemblies distributed side by side, a first shell 13 arranged on the connecting pipe group, a telescopic mechanism 14 arranged in the first shell 13, and a rack 15 connected to the end of the telescopic mechanism 14. The telescopic mechanism 14 can adopt an electric push rod, a hydraulic cylinder, or an air cylinder. A slide rail can also be provided in the first shell 13, and the rack 15 is slidably set 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 provided on the first rotating shaft 17 and meshingly connected to the rack 15, a first bevel gear 18 provided 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 meshedly 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 drives the rack 15 to reciprocate, which in turn rotates two first gears 16. The first gear 16 then rotates a first bevel gear 18 via a first rotating shaft 17. The first bevel gear 18 then rotates a second bevel gear 19. The second bevel gear 19 then rotates the first valve plate 12 via a second rotating shaft 20, thereby switching the first valve plate 12 between a horizontal and vertical position. Switching between these two positions requires rotating the second rotating shaft 20 180°.

[0038] Example 3

[0039] like Figure 1-Figure 5 As shown, this embodiment provides an integrated sewage treatment device. Compared to the first embodiment, the filter assembly in this embodiment includes a cylindrical filter frame 31 that is rotatably mounted on the inner wall of the cleaning tube 4 and a filter element 32 disposed inside the filter frame 31. The filter element 32 filters fluff on the inside, while the filter frame 31 rotates on the outside. Increasing the speed of the filter frame 31 can help remove fluff from the filter element 32 using centrifugal force.

[0040] The second valve plate 38 is rotatably mounted on the inner wall of the second bulb 6. The drive device includes a second housing 21 mounted on the cleaning tube 4, a motor 22 mounted within the second housing 21, a second gear 23 connected to the output end of the motor 22, a third shaft 25 rotatably mounted on the second housing 21, a third gear 24 mounted on the third shaft 25 and meshingly connected to the second gear 23, a third bevel gear 26 and a fifth bevel gear 35 respectively mounted at both ends of the third shaft 25, a mounting cover 29 extending through the cleaning tube 4, a fourth shaft 28 rotatably mounted on the mounting cover 29, a fourth bevel gear 27 respectively mounted at both ends of the fourth shaft 28, a connecting frame 30, a fifth shaft 37 rotatably mounted on the second bulb 6, and a sixth bevel gear 36 mounted at one end of the fifth shaft 37 and meshingly connected to the fifth bevel gear 35. The connecting frame 30 is connected to the filter assembly. The fourth shaft 28 and the fifth shaft 37 form a 45° angle. The fifth shaft 37 is connected to the second valve plate 38. The second valve plate 38 is in a blocking 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 drives the second gear 23 to rotate. The second gear 23 drives the third rotating shaft 25 to rotate via 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 via the fourth rotating shaft 28 and the connecting frame 30, thereby pushing and cleaning fluff and dirt. The fifth bevel gear 35 drives the second valve plate 38 to rotate via the sixth bevel gear 36 and the fifth rotating shaft 37. To switch the second valve plate 38 between a vertical and horizontal position, the fifth rotating shaft 37 needs to be rotated 180 degrees.

[0042] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
