During this process, part of the weaving size, lubricant, oil agent and other impurities will be mixed into the water to form wastewater.

[0003] When the gas float method is used to treat the wastewater generated in the weaving process, the air pipe is inserted into the inside of the treatment tank, the holes are arranged on the pipe, the gas can be discharged at the holes, the gas can form highly dispersed micro-bubbles, adhere to the solid or liquid particles with hydrophobic groups in the wastewater, form a three-phase mixed system of water, gas and particles, and the particles adhere to the bubbles to form flocculation with a smaller apparent density than water to float up.

[0020] Compared with the prior art, the present application has the following advantages:

[0021] First, the pipeline cleaning assembly and the lifting mechanism are arranged in the present application. After sewage is discharged, the lifting mechanism is started to drive the pipeline cleaning assembly to rotate downwardly and rotate to a horizontal state. At this time, the steel wire brush is aligned with the air pipe, and the guide rail and the air pipe are aligned vertically. The steel wire brush moves along the guide rail under the driving of the threaded rod and other components. The part of the air pipe exposed outside the mounting groove can be wiped, and the stains adhered to the outer wall of the part can be removed. At the same time, the oil removal agent spraying mechanism is arranged at the guide rail, and the oil removal agent can be sprayed to the steel wire brush. In this way, it is easier to wipe the stains and oil on the outer wall of the air pipe. The stains are usually adhered by oil, and the oil is decomposed by the oil removal agent, which reduces the difficulty of removal and improves the removal effect. The part of the air pipe in contact with the sewage is kept clean, the environment of the treatment tank is improved, and the coating on the outer surface of the air pipe can stably exist.

[0022] Second, in the present application, sewage enters the treatment tank, is intercepted by the grid plate in the filter tank, and the remaining sewage enters the air flotation treatment tank through the connecting pipe. Gas flows in the multiple air pipes on the inside bottom of the air flotation treatment tank. The gas is discharged through the gas outlet to form highly dispersed micro-bubbles, which adhere to the solid or liquid particles of the hydrophobic group in the waste water to form a three-phase mixed system of water, gas and particles. After the particles adhere to the bubbles, the apparent density of the flocculation is less than that of water, so that the flocculation floats up. At the same time, the oil in the sewage also floats on the upper layer of the water body, and the floating oil and impurities are removed through the floating material discharge pipe to treat the oil and impurities in the sewage generated during the weaving process.

[0023] Third, during the process of rotating the pipeline cleaning assembly downwardly by the lifting mechanism, the winding motor needs to be started to drive the steel wire rope winding roller to loosen the wound steel wire rope. The pipeline cleaning assembly connected by the steel wire rope rotates downwardly along the hinged seat. During this period, the steel wire rope winding roller drives the connecting rope winding roller to rotate in the opposite direction through the gear set to tighten the connecting rope wound thereon, thereby pulling the bottom plate and the plugging rod to move upwardly. When the pipeline cleaning assembly is in a horizontal state, the plugging rod blocks the gas outlet to prevent the stains from being pushed into the air pipe during the cleaning process of the pipeline cleaning assembly, thereby keeping the air pipe unobstructed.

[0037] Further, the air float type treatment pool 102 is provided with a floating material discharge pipe 4 at the top inside and a sewage discharge pipe 5 at the bottom, after the air pipe 7 passes gas into the air float type treatment pool 102, it can form highly dispersed micro-bubbles, which adhere to the hydrophobic solid or liquid particles in the wastewater, forming a three-phase mixed system of water, gas and particles, and the particles adhere to the bubbles to form a floe with a apparent density less than water, thereby floating up, at the same time, the oil in the wastewater also floats on the upper layer of the water, the floating material discharge pipe 4 is located at this liquid level, through which the floating material in the wastewater can be sucked away, and the sewage discharge pipe 5 discharges the wastewater treated by air float method in the air float type treatment pool 102 to the next process.

[0038] Further, the air float type treatment pool 102 is provided with a pipe cleaning assembly 8, which is used to clean the part of the air pipe 7 exposed outside the installation groove, and the air float type treatment pool 102 is provided with a clean water feeding pipe 6 inserted at the top, which can send clean water into the air float type treatment pool 102, when the pipe cleaning assembly 8 cleans the outer wall of the air pipe 7, the sending of clean water can flush away the stains wiped off the outer wall of the air pipe 7.

[0039] Specifically, the pipeline cleaning assembly 8 is connected with the inner wall of the air flotation treatment tank 102 through the hinged seat 9. The pipeline cleaning assembly 8 comprises a top plate 801 and a guide rail. The top plate 801 is connected with the hinged seat 9 and can rotate around the connecting rod in the hinged seat 9. A sliding block 802 is installed in the guide rail. The sliding block 802 is connected with a driving mechanism for driving the sliding block 802 to move along the guide rail. The driving mechanism comprises a threaded rod 803 and a driving motor 806. The output end of the driving motor 806 is connected with the threaded rod 803 through a shaft coupling. The threaded rod 803 is connected with the sliding block 802 through threads. The length of the threaded rod 803 is longer than the length of the air pipe 7 inserted into the air flotation treatment tank 102. A support 804 is arranged on the side of the sliding block 802 close to the air pipe 7. A steel wire brush 805 is arranged in the support 804. It is to be noted that an oil removing agent spraying mechanism 807 is arranged at the end of the guide rail away from the hinged seat 9. The oil removing agent spraying mechanism 807 comprises a storage tank in which spraying pipes are inserted. The spraying pipes are connected with a power pump for driving the oil removing agent in the storage tank to flow. When the sliding block 802 is at the point farthest away from the hinged seat 9, the outlet of the spraying pipe is aligned with the steel wire brush 805. The oil removing agent is a surfactant, such as Texent 610A. The oil removing agent is mixed with the steel wire brush 805. The steel wire brush 805 can more conveniently remove the oil stains on the outer wall of the air pipe 7 during the movement of the steel wire brush 805. The oil removing agent spraying mechanism 807 can spray the oil removing agent to the steel wire brush 805. The oil removing agent spraying mechanism 807 is arranged at the end away from the hinged seat 9. According to the principle of the lever, the gravity of the oil removing agent spraying mechanism 807 can make the top plate 801 have a tendency to rotate downward. Therefore, when the steel wire rope 1001 is loosened, the top plate 801 can fall around the hinged seat 9.

[0040] Further, the pipeline cleaning assembly 8 is connected with a lifting mechanism 10. The lifting mechanism 10 is used to drive the pipeline cleaning assembly 8 to rotate around the connecting rod in the hinged seat 9.

Figure 1 As shown in the figure, the pipeline cleaning assembly 8 is in the horizontal state. At this time, the sliding block 802 is aligned with the air pipe 7, and the guide rail is parallel to the air pipe 7. The steel wire brush 805 can move along the outer wall of the air pipe 7 during the movement of the sliding block 802 and the steel wire brush 805. The steel wire brush 805 can wipe the oil stains on the outer wall of the air pipe 7. When the pipeline cleaning assembly 8 is in the lifted state, the pipeline cleaning assembly 8 is lifted upward. The components such as the steel wire brush 805 and the sliding block 802 are separated from the sewage, so that a large amount of waste oil and waste water is not adhered to the steel wire brush 805.

[0041] Specifically, the lifting mechanism 10 includes a steel wire rope 1001, the steel wire rope 1001 is wound on a steel wire rope winding roller 1002, the steel wire rope winding roller 1002 is connected with a winding motor 1003 for driving the steel wire rope winding roller 1002 to rotate forward and backward, the winding motor 1003 has a self-locking function, one end of the steel wire rope 1001 is connected with the top plate 801, and the steel wire rope 1001 penetrates the side plate and has a gap with the inner wall of the through hole in the side plate; the gap is small.

[0042] When the pipeline cleaning assembly 8 cleans the oil and stains adhered to the outer wall of the breather pipe 7, the steel wire brush 805 moves along the outer wall of the breather pipe 7 and easily pushes the stains into the air outlet 701, and the stains enter the breather pipe 7 from the air outlet 701, which easily causes the breather pipe 7 or the air outlet 701 to be blocked, so the blocking assembly 11 is arranged in the breather pipe 7, and when the pipeline cleaning assembly 8 is in a horizontal state, the blocking assembly 11 blocks the air outlet 701 in the breather pipe 7;

[0043] Specifically, the blocking assembly 11 includes a bottom plate 1101, the bottom plate 1101 is provided with a blocking rod 1102 corresponding to the air outlet 701, the bottom plate 1101 is clamped between two left and right guide plates 1103, and the bottom plate 1101 and the front and rear guide plates 1104 can only slide up and down relative to each other, the bottom plate 1101 is provided with a connecting rope 1105, the other end of the connecting rope 1105 is wound on a connecting rope winding roller 1106, and the connecting rope winding roller 1106 and the steel wire rope winding roller 1002 are connected through a gear set, the gear set is used to make the rotating directions of the connecting rope winding roller 1106 and the steel wire rope winding roller 1002 opposite, and the steel wire rope winding roller 1002 rotates several turns while the connecting rope winding roller 1106 only rotates half a turn, the gear set includes a large gear 1107 and a small gear 1108, the large gear 1107 and the small gear 1108 are connected through tooth engagement, the large gear 1107 is arranged on the connecting rope winding roller 1106, and the steel wire rope winding roller 1002 and the connecting rope winding roller 1106 are arranged in a storage box 1109.

[0044] Specifically, the breather pipe 7 is connected with an air inlet pipeline 12, the air inlet pipeline 12 can send external gas into the breather pipe 7, and the gas is discharged through the air outlet 701 in the breather pipe 7.

[0045] Working principle:

[0046] The sewage enters the treatment tank 1, and the larger sundries are intercepted by the grid plate 2 in the filter tank 101, and the remaining sewage enters the air flotation treatment tank 102 through the communication pipe 3. The gas flows in the plurality of air pipes 7 at the bottom of the air flotation treatment tank 102, and the gas is discharged through the gas outlet 701 to form highly dispersed micro-bubbles, which adhere to the solid or liquid particles of the hydrophobic group in the wastewater to form a three-phase mixed system of water, gas and particles. After the particles adhere to the bubbles, the flocculation with a smaller apparent density than water is formed to float upwards. At the same time, the oil in the sewage also floats on the upper layer of the water body. The floating oil and impurities are removed through the floating material discharge pipe 4, and then the remaining sewage is discharged to the next process through the sewage discharge pipe 5.

[0047] After the sewage is discharged, the lifting mechanism 10 is started to drive the pipeline cleaning assembly 8 to rotate downward to the horizontal state. At this time, the steel wire brush 805 is aligned with the air pipe 7, and the guide rail is aligned with the air pipe 7 up and down. The steel wire brush 805 moves along the guide rail under the driving of the threaded rod 803 and the like to wipe the part of the air pipe 7 exposed outside the mounting groove. At the same time, the oil removal agent spraying mechanism 807 is arranged at the guide rail to spray the oil removal agent to the steel wire brush 805. In this way, it is easier to wipe the dirt and oil on the outer wall of the air pipe 7. The dirt is usually adhered by the oil, and after the oil is decomposed by the oil removal agent, the difficulty of removing the dirt is greatly reduced.

[0048] During the process of rotating the pipeline cleaning assembly 8 downward by the lifting mechanism 10, the winding motor 1003 is started to drive the steel wire winding roller 1002 to loosen the wound steel wire 1001. The pipeline cleaning assembly 8 connected by the steel wire 1001 rotates downward along the hinge seat 9. During this period, the steel wire winding roller 1002 drives the connecting rope winding roller 1106 to rotate in the opposite direction through the gear set to tighten the connecting rope 1105 wound thereon, and then pulls the bottom plate 1101 and the blocking rod 1102 to move upward. When the pipeline cleaning assembly 8 is in the horizontal state, the blocking rod 1102 blocks the gas outlet 701.

[0049] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
