Description

Technical Field

[0001] This invention relates to the field of textile wastewater treatment technology, specifically to a wastewater treatment device for nonwoven fabric waste. Background Technology

[0002] Nonwoven fabric is a type of textile fabric. During the production of nonwoven fabric, a large amount of wastewater is generated from washing or dyeing. In order to achieve the sustainable development of washing or dyeing, the treatment of nonwoven fabric wastewater is extremely necessary.

[0003] Currently, the treatment of non-woven fabric wastewater mainly adopts a combination of pretreatment, biological treatment and advanced treatment processes. In the existing pretreatment stage of non-woven fabric wastewater, fibers, large particulate impurities or flocculated dirt in the wastewater need to be intercepted by grids or filters. However, this interception method has great drawbacks. As the amount of dirt on the grids or filters increases, the flow rate of wastewater through the grids or filters will be greatly hindered. In severe cases, the grids or filters may be damaged due to excessive water pressure. With the increase of the service time, the interception efficiency of the grids or filters for dirt will become lower and lower.

[0004] In view of this, a wastewater treatment device for non-woven fabrics was designed to solve the above problems. Summary of the Invention

[0011] In a preferred embodiment, the present invention may be further configured such that: a sludge-collecting hood is fixedly installed on the outside of the sewage hood, and a sloping groove for storing sludge is reserved inside the sewage hood and the sludge-collecting hood.

[0012] In a preferred embodiment, the present invention can be further configured as follows: a clamp is fixedly installed on the guide tube, two supports are installed inside the clamp, and a sludge storage tank is fixedly installed at the bottom of the two supports.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0022] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of a nonwoven wastewater treatment device provided by the present invention.

[0024] Example 1: Combination Figures 1 to 8 As shown, the present invention provides a wastewater treatment device for non-woven fabric waste, including a wastewater removal mechanism 100, a protective power supply mechanism 200 installed on the wastewater removal mechanism 100, and an auxiliary mechanism 300 installed in the wastewater removal mechanism 100 and the protective power supply mechanism 200. The wastewater removal mechanism 100 includes a water storage tank 110, inside which is installed a built-in vertical pipe 120. Symmetrically distributed inlet pipes 130 and outlet pipes 140 are installed on both sides of the bottom of the water storage tank 110, with a filter screen 1401 installed at the top of the outlet pipe 140. A sludge hood 160 is installed on the top of the water storage tank 110, and baffles 1602 are installed in three recesses at the top of the sludge hood 160. A shaft 160 is inserted into each baffle 1602. 3. The shaft 1603 is installed in the inner wall of the groove. Three symmetrically distributed support plates 1604 are fixedly installed on the inner wall of the drain cover 160. The support plates 1604 are located at the bottom of the groove. A tension spring 1605 is fixedly installed on the support plate 1604. The top of the tension spring 1605 is fixedly connected to the baffle 1602. A sludge collection cover 1601 is fixedly installed on the outside of the drain cover 160. The drain cover 160 and the sludge collection cover 1601 are reserved with inclined grooves for storing sludge. The outer surface of the sewage hood 160 and the inner wall of the sewage collection hood 1601 are both covered with a smooth enamel layer. The protective power supply mechanism 200 includes a guide outer pipe 210 fixedly installed on the built-in vertical pipe 120. The outer wall and bottom of the guide outer pipe 210 are provided with slots. A load-bearing frame 240 is fixedly installed in the middle of the guide outer pipe 210. A housing 250 is fixedly installed on one side of the load-bearing frame 240. A motor 2501 is installed inside the housing 250. A deflection gear 2502 is installed on the motor 2501. Two symmetrical through holes are provided in the middle of the load-bearing frame 240. The assist mechanism 300 includes a cable 320 that extends through the guide pipe 210 and the water storage tank 110. Multiple anti-seepage pads 330 are evenly distributed on the cable 320. Three soft rubber rods 3301 are symmetrically distributed on the anti-seepage pads 330. A main shaft 350 is movably installed in two through holes. A drive wheel 3501 is installed on the main shaft 350. A gear 3502 is fixedly installed at one end of the main shaft 350. The gear 3502 is adapted to mesh with the deflection gear 2502. The drive wheel 3501 is located inside the load-bearing frame 240, and multiple corner plates on the side of the drive wheel 3501 are adapted to bear pressure on the seepage-proof pad 330, which helps the cable 320 and multiple seepage-proof pads 330 to rotate at a constant speed along the inner cavity of the guide outer pipe 210 and the built-in vertical pipe 120. The anti-seepage pad 330 has a funnel-shaped structure. Three adjacent soft rubber rods 3301 are fixedly installed on the pipe section at the top of the anti-seepage pad 330, and anti-seepage rubber rings are provided on the side of the anti-seepage pad 330.

[0025] When in use, the water storage cylinder 110 is fixedly installed on the workbench using an external clamp. Then, the outer end of the inlet pipe 130 is connected to the sewage pipe. As the sewage is drawn into the inner cavity of the water storage cylinder 110 through the inlet pipe 130, the sewage with added flocculant will increase the aggregation of large pieces of dirt when it enters the inner cavity of the water storage cylinder 110. As motor 2501 starts and runs, motor 2501, in conjunction with deflection gear 2502, drives gear 3502, which in turn drives main shaft 350 to rotate. Ultimately, drive wheel 3501 rotates at a constant speed along the interior of load-bearing frame 240. This constant rotation of drive wheel 3501 propels multiple evenly distributed anti-seepage pads 330. At this time, the multiple anti-seepage pads 330 connected to cable 320 are guided and pressure-bearing by guide tube 210 and internal vertical tube 120. The multiple anti-seepage pads 330 and cable 320, pushed by drive wheel 3501, move along the guide tube 210 and internal vertical tube 120. The outer pipe 210 and the built-in vertical pipe 120 rotate at a constant speed. When the anti-seepage pad 330 and the three soft rubber rods 3301 on its pipe section enter the inner cavity of the water storage tank 110, the large clumps of flocculated dirt in the sewage in the inner cavity of the water storage tank 110 will be intercepted and hooked by the soft rubber rods 3301. Finally, the dirt intercepted and hooked by the soft rubber rods 3301 will be transferred to the outside of the drain cover 160. Until the moment the soft rubber rods 3301 move and stick to the top pipe section of the guide outer pipe 210, the soft rubber rods 3301, which are bent by pressure, will quickly discharge the dirt. Finally, the discharged dirt will be stored in the drain cover 160 and the dirt collection cover 1601.

[0026] Example 2: Combination Figure 4 As shown, based on Embodiment 1, a clamp 220 is fixedly installed on the guide tube 210. Two brackets 2201 are installed inside the clamp 220, and a sludge storage tank 230 is fixedly installed at the bottom of the two brackets 2201. A cover plate 2301 is provided at the outer end of the sludge storage tank 230. Two bolts 2302 are inserted into the cover plate 2301, and the two bolts 2302 are threaded into the sludge storage tank 230. The ports at the top of the sludge storage tank 230 and the cover plate 2301 are located directly below the bottom slot of the guide pipe 210 and are used to store sludge remaining on the slope of the anti-seepage pad 330.

[0027] Preferably, two brackets 2201 are welded to the plate end of the sludge storage tank 230. The distance between the top of the sludge storage tank 230 and the bottom groove of the guide tube 210 is adjusted by using the clamp 220 until the top port of the sludge storage tank 230 and the top port of the cover plate 2301 are adapted and aligned with the bottom groove of the guide tube 210. As the cable 320 and multiple anti-seepage pads 330 rotate at a constant speed inside the guide pipe 210, when the anti-seepage pads 330 pass through the bottom pipe of the guide pipe 210 and its bottom groove, the dirt remaining on the inclined surface of the anti-seepage pads 330 will be quickly discharged from the bottom groove of the guide pipe 210 and effectively stored by the sludge storage tank 230 and the cover plate 2301. The inner wall of the guide tube 210 has a smooth coating structure.

[0028] Example 3: Combination Figures 4 to 7 As shown, in the above embodiment, a transmission pulley 3503 is fixedly installed at the other end of the main shaft 350. A transmission belt 340 is connected to the transmission pulley 3503. A linkage pulley 3103 is connected to the other end of the transmission belt 340. An impeller 3102 is installed inside the linkage pulley 3103. A bellows 310 is provided outside the impeller 3102. An insertion hole 3101 is provided on the back of the bellows 310. The water storage cylinder 110 has multiple air holes 1101 on its cylinder wall. An annular air cover 150 is installed on the outside of the water storage cylinder 110. A guide pipe 1501 is installed on the annular air cover 150, and the other end of the guide pipe 1501 is fixedly installed in the insertion hole 3101. An outer pad 1102 and an inner pad 1103 are fixedly installed at the bottom of the inner cavity of the water storage cylinder 110. The inner wall of the outer pad 1102 and the outer wall of the inner pad 1103 are both arc-shaped structures.

[0029] Preferably, the guide pipe 1501 is welded inside the insertion hole 3101, and the air box 310 has a ventilation opening on the plate surface away from the annular air cover 150. As the main shaft 350 drives the transmission pulley 3503 to rotate, the transmission pulley 3503 will drive the transmission belt 340 and the linkage pulley 3103. Finally, the linkage pulley 3103 will drive the impeller 3102 to rotate at high speed, and the air in the environment will be actively drawn into the inner cavity of the air box 310. As the airflow continues to enter the interior of the annular air cover 150, the airflow will be transferred from the groove on the inner wall of the annular air cover 150 and the corresponding multiple air holes 1101 to the sewage in the inner cavity of the water storage tank 110. During the process of cleaning and removing impurities from the sewage, the water quality can be improved by aeration, further enhancing the aggregation of flocculated matter in the sewage.

[0030] The working principle and usage process of this invention: Non-woven fabric wastewater treatment requires pretreatment to intercept large suspended solids in the wastewater. After pretreatment, the wastewater needs to undergo coagulation and flotation treatment. Small particles of dirt in the wastewater are flocculated by adding coagulants or oil removers. Then, the flocculated wastewater undergoes further treatment, and then the further treated wastewater is further treated and disinfected for reuse. In the above process, the treatment of flocculated sludge in the pretreatment stage and the coagulation and flotation treatment stage will cause the grid or filter screen to become clogged. As the amount of flocculated sludge gradually increases, the mesh of the grid or filter screen will deform due to the increase in water pressure. Therefore, this device can replace the pretreatment tank and the coagulation and flotation treatment tank as a highly efficient purification device for removing impurities. Wastewater from non-woven fabric is pre-introduced into the inner cavity of the storage tank 110 through the inlet pipe 130. Then, the motor 2501 is started via the client. The motor 2501, in conjunction with the deflection gear 2502, drives the gear 3502. At this time, the gear 3502, main shaft 350, and transmission pulley 3503 are driven, and the drive wheel 3501 drives the bellows 310 and multiple evenly distributed anti-seepage pads 330 to rotate at a constant speed. The rotating anti-seepage pads 330 rotate regularly along the inner cavity of the guide pipe 210. The bottom section of the guide pipe 210 is fixedly connected to the bottom end of the built-in vertical pipe 120. Therefore, the evenly distributed anti-seepage pads 330 rotate upwards along the inside of the built-in vertical pipe 120, and the anti-seepage pads... After the three soft rubber rods 3301 on the seepage pad 330 detach from the inside of the built-in vertical pipe 120 and enter the inner cavity of the water storage tank 110, the three soft rubber rods 3301, which lose pressure, will quickly expand and straighten, and the flocculated and suspended waste in the sewage in the inner cavity of the water storage tank 110 can be intercepted. Until the soft rubber rods 3301 rise from the bottom slope of the baffle 1602, the baffle 1602, which is squeezed, will quickly flip outward until the soft rubber rods 3301 transfer the intercepted dirt to the top of the drain hood 160. When the soft rubber rods 3301 contact the top pipe section of the guide outer pipe 210, the compressed soft rubber rods 3301 bend to the side and quickly discharge the intercepted dirt. Finally, the dirt will be stored in the drain hood 160 and the inclined groove of the dirt collection hood 1601. Meanwhile, the transmission pulley 3503 drives the transmission belt 340, which in turn drives the linkage pulley 3103 and the impeller 3102. As the impeller 3102 rotates, outside air is drawn into the inner cavity of the air box 310. Finally, the airflow enters the interior of the annular air hood 150 through the guide pipe 1501. The airflow entering the annular air hood 150 is then sent towards the inner cavity of the water storage tank 110 along multiple air holes 1101. The sewage inside the water storage tank 110 is efficiently aerated, and the flocculated sludge is accelerated to rise and be dynamically intercepted by the rotating air box 310, multiple anti-seepage pads 330, and multiple soft rubber rods 3301. While the sewage is being dynamically cleaned, the drain pipe 140 and the filter screen 1401 can further purify the sewage inside the water storage tank 110.
