DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand: the present invention is further explained below in conjunction with specific implementation methods.

[0030] like Figures 1 to 7 As shown, the present invention provides a technical solution: a device for treating wastewater produced by spunlaced nonwoven fabrics, comprising a wastewater treatment box 1, a water inlet pipe 2 is arranged on one side of the wastewater treatment box 1, a water outlet pipe 3 is arranged on the other side of the wastewater treatment box 1, the water inlet pipe 2 and the water outlet pipe 3 are used to discharge wastewater in and out of the wastewater treatment box 1, a filter plate 4 is arranged inside the wastewater treatment box 1, the outer wall of the filter plate 4 is slidably connected to the inner wall of the wastewater treatment box 1, the water inlet pipe 2 is located above the filter plate 4, the water outlet pipe 3 is located below the filter plate 4, a pull rope assembly is arranged on the top of the wastewater treatment box 1, the pull rope assembly is used to pull the filter plate 4 to the top of the wastewater treatment box 1, a tilting assembly is arranged on the top of the filter plate 4, the tilting assembly enables the filter plate 4 to tilt when it rises, a stirring assembly is arranged on the bottom of the filter plate 4, the stirring assembly is located inside the wastewater treatment box 1, and the stirring assembly can make the stirring assembly work when the filter plate 4 rises.

[0031] During operation: In the wastewater generated by the existing non-woven fabric production, the treatment of suspended matter and solid sediment is the most important link. When the wastewater enters the treatment box, the wastewater will pass through the filter plate, so that the solid sediment is filtered onto the filter plate, and then the filter plate is raised to the top of the treatment box, which can collect the solid sediment from the filter plate while also being able to salvage the suspended matter. However, after the filter plate is taken out, there is still a large amount of wastewater on its surface. Slowly controlling the drying of the wastewater will prolong the time of the entire treatment process, resulting in reduced treatment efficiency, thereby increasing the time and cost of treatment. Through the embodiment of this scheme, during specific use, the water inlet pipe 2 is connected to the wastewater discharge port, so that the wastewater enters the wastewater treatment box 1, and the water outlet pipe 3 is connected to the next step of wastewater treatment device, so that the treated wastewater is discharged from the wastewater treatment box 1. When the wastewater enters the wastewater treatment box 1, and when the incoming amount submerges the filter plate 4, the injection of wastewater is stopped, and the wastewater will pass through the filter plate 4. The filter plate 4 is filtered through the filter plate 4, so the solid sediment will be filtered to the top of the filter plate 4, and then the filter plate 4 is raised to the top of the wastewater treatment tank 1 through the pull rope assembly. During the rising process of the filter plate 4, the suspended matter and the solid sediment on the filter plate 4 can be separated from the water, and the filter plate 4 is driven to rise, and the filter plate 4 will drive the stirring assembly to work during the rising process, so that the reactant and the wastewater are fully mixed and reacted. When the filter plate 4 rises to a certain height, it will touch the tilting assembly, so that the filter plate 4 is in a tilted state just above the wastewater treatment tank 1, so that the wastewater attached to its surface quickly flows into the wastewater treatment tank 1, reducing the time that the wastewater stays on the surface of the filter plate, effectively reducing the phenomenon of slowly drying, and can also reduce the residue of wastewater on the surface of the filter plate. The filter plate 4 is in a tilted state, which is convenient for the staff to better clean the suspended matter and solid sediment on the surface of the filter plate 4.

[0032] like Figure 5 to Figure 6 As shown, both sides of the filter plate 4 are fixedly connected with an articulated seat 1 5, and the tops of the two articulated seats 1 5 are fixedly connected with an articulated seat 2 6. The pull rope assembly includes two rope rings 7, and the two rope rings 7 are respectively fixedly connected to the tops of the two articulated seats 2 6. The outer walls of the two rope rings 7 are fixedly connected with a pulling rope 8, and the ends of the two pulling ropes 8 away from the rope rings 7 are fixedly connected with a rope winding shaft 9. A driving assembly is provided on one side of the rope winding shaft 9, and the driving assembly is used to drive the two rope winding shafts 9 to rotate simultaneously.

[0033] When working: start the driving component, the two rope winding shafts 9 will rotate at the same time. When the rope winding shafts 9 rotate, the tension ropes 8 will be wound around the outer walls of the rope winding shafts 9, thereby pulling the filter plate 4 upward, so that the filter plate 4 can rise from the inside of the wastewater treatment tank 1 to the top of the wastewater treatment tank 1. The filter plate 4 can salvage suspended matter in the wastewater during the rising process, and after rising to the top of the wastewater treatment tank 1, it is convenient for the staff to collect these debris, which is convenient for the subsequent use of the filter plate 4. Similarly, the filter plate 4 can also be lowered and restored to its original position through the driving component.

[0034] like Figure 5 to Figure 6 As shown, the driving assembly includes a motor 15, which is fixedly installed on one side of the wastewater treatment tank 1, and the output shaft of the motor 15 is fixedly connected to a driving gear 14, the outer wall of the driving gear 14 is transmission-connected to a transmission tooth chain 13, and the inner walls of both ends of the transmission tooth chain 13 are transmission-connected to driven gears 12, and one side of the two driven gears 12 is fixedly connected to a rotating rod 10, and the two rotating rods 10 are respectively fixedly connected to two rope winding shafts 9, and the outer wall of the rope winding shaft 9 is rotationally connected to a clamping member 11, and the clamping member 11 is fixedly installed on the outer side of the wastewater treatment tank 1.

[0035] During operation: start the motor 15, and its output shaft will drive the driving gear 14 to rotate. When the driving gear 14 rotates, it will drive the transmission tooth chain 13 to transmit. When the transmission tooth chain 13 transmits, it will drive the two driven gears 12 to rotate. The two driven gears 12 will drive the rope winding shaft 9 to rotate through the two rotating rods 10, so that the tension rope 8 can be wound around the outer wall of the rope winding shaft 9, so as to achieve the effect of lifting the filter plate 4. The clamping part 11 fixes the position of the rotating rod 10 and the rope winding shaft 9, thereby improving the stability of the tension rope 8 when it is pulled up.

[0036] like Figure 5 to Figure 6 As shown, the outer walls of the two tension ropes 8 are respectively connected to a movable pulley 16 and a movable pulley 17, the movable pulley 17 is located directly above the rope ring 7, and the movable pulley 16 is located directly above the rope winding shaft 9. The rotating shafts of the movable pulley 16 and the movable pulley 17 are both rotatably connected to a double-axis clamp 18.

[0037] During operation: the pulling direction of the tension rope 8 is changed by the movable pulley 16 and the movable pulley 2 17. The movable pulley 2 17 is located directly above the rope ring 7, so that the filter plate 4 always maintains a vertical state during the rising process, and has higher stability, and can accurately touch the tilting component when it rises. The movable pulley 16 is located directly above the rope winding shaft 9, so that the other end of the tension rope 8 can always be wound on the outer wall of the rope winding shaft 9, and the double-axis clamp 18 fixes the position of the movable pulley 16 and the movable pulley 2 17.

[0038] like Figure 2 and Figure 6 As shown, a connecting rod 19 is fixedly connected between the two hinged seats 6 , a round block 20 is symmetrically fixedly connected to the top of the connecting rod 19 , and the tilting assembly is located directly above the round block 20 .

[0039] During operation: when the filter plate 4 rises, the round block 20 will also rise. When the round block 20 rises to a certain height, it will enter the tilting assembly and will be squeezed by the tilting assembly as it continues to rise, causing the round block 20 to rotate a certain angle. Therefore, the connecting rod 19 will also rotate a certain angle, and the filter plate 4 will rotate a certain angle through the hinge seat 2 6 and the hinge seat 1 5, thereby achieving the effect of the filter plate 4 being tilted.

[0040] like Figure 6 to Figure 7 As shown, the tilting assembly includes a right-angle table 24, and the dual-axis clamps 18 are fixedly installed on the top of the right-angle table 24. A connecting frame 25 is fixedly connected to one side of the right-angle table 24, and the connecting frame 25 is fixedly installed on one side of the wastewater treatment tank 1. The tilting surface of the right-angle table 24 is symmetrically fixedly connected to a tilting seat 22, and side slide grooves 23 are provided on both sides of the tilting seat 22. The two sides of the two round blocks 20 are fixedly connected to the limiting blocks 21.

[0041] During operation: since the two tilting seats 22 are fixedly mounted on the tilted surface of the right-angle platform 24, the tilting seat 22 always maintains an inclined state. During the rising process of the filter plate 4, the round block 20 will slowly enter the inner wall of the tilting seat 22, and when the round block 20 completely enters the inner wall of the tilting seat 22, when the round block 20 continues to rise, the shafts on both sides of the round block 20 will slide along the side slide grooves 23, and the round block 20 will slide along the inner wall of the tilting seat 22, so that the connecting rotating rod 19 rotates a certain angle, and the limit block 21 can maintain stability during the sliding process. The side slide groove 23 is provided with multiple gears. When the round block 20 slides inside the tilting seat 22 so that the connecting rotating rod 19 rotates, the shaft of the round block 20 will pass through different gears. Therefore, when the shaft of the round block 20 is above different gears, the filter plate 4 is tilted at different angles. The higher the position, the greater the inclination angle, thereby effectively controlling the flow rate of the downstream wastewater. When the connecting rotating rod 19 drives the filter plate 4 to tilt, the wastewater retained on the surface of the filter plate 4 will flow down quickly under the action of gravity and return to the interior of the wastewater treatment tank 1 without waiting for a long time to dry. When the shaft rods on both sides of the round block 20 slide along the side slide groove 23, the inclination angle of the filter plate 4 gradually increases, and according to actual conditions, the round block 20 can drive the filter plate 4 to tilt at an angle that is just enough to control the water while not affecting the falling of impurities. By tilting the filter plate 4, the wastewater can flow back from the surface of the filter plate 4 to the wastewater treatment tank 1 more quickly and effectively, which contributes to the smoothness and efficiency of the overall treatment process, significantly reduces the time that the wastewater stays on the surface of the filter plate, and effectively reduces the phenomenon of slow drying.

[0042] It is explained that in the process of tilting the filter plate 4 to control the moisture on the surface, the angle at which the filter plate needs to be tilted is very important, and the tilting angle can be determined according to the scheduling formula θ=arctan(L⋅T / W⋅g⋅K)⋅F, wherein θ (tilt angle), W (weight or volume of residual moisture), g (gravitational acceleration), K (a comprehensive coefficient related to the material and structure of the filter plate), L (length or width of the filter plate, used to calculate the distance from the gravity line of the residual moisture to the tilting axis), T (thickness of the filter plate), and F (safety factor). During specific control, the optimal tilting angle of the filter plate 4 is calculated through the scheduling formula, and the motor 15 is operated through the control panel to drive the length of the tension rope 8 wound on the rope winding shaft 9, thereby driving the round block 20 to rise. As the round block 20 gradually rises, the tilting angle of the filter plate 4 gradually increases.

[0043] like Figure 4 As shown, a collecting box 33 is arranged on the top of the wastewater treatment box 1, and a filter screen 34 is fixedly connected to the bottom of the inner side of the collecting box 33.

[0044] During operation: when the filter plate 4 is tilted, the suspended matter and solid sediment on its surface will flow into the collection box 33 under the action of gravity, and the staff can knock on the surface of the filter plate 4 with tools to make these impurities fall into the collection box 33 more completely, and then the collection box 33 can be removed to clean the impurities, and the filter screen 34 can be used to allow a part of the water flowing into the collection box 33 to flow into the wastewater treatment box 1 through the filter screen 34 in the tilted state.

[0045] like Figures 2 to 3 As shown, the stirring assembly includes two stirring rods 31, and the outer walls of the two stirring rods 31 are fixedly connected with a plurality of stirring blades 32. The outer walls at the center of the two stirring rods 31 are fixedly connected with an internal gear 30. A linkage assembly is provided on one side of the internal gear 30, and the linkage assembly drives the two internal gears 30 to rotate.

[0046] During operation: when the filter plate 4 rises, the internal gear 30 will rotate through the linkage assembly. When the internal gear 30 rotates, it will drive the stirring rod 31 to rotate. When the stirring rod 31 rotates, the stirring blade 32 will stir the wastewater inside the wastewater treatment box 1, so that the added reactant and the wastewater can fully react, ensuring that the reactant and the pollutants in the wastewater are fully in contact and react, thereby accelerating the removal or conversion process of the pollutants.

[0047] like Figures 2 to 3 As shown, the linkage assembly includes two articulated seats 5, the bottoms of the two articulated seats 5 are fixedly connected to two connecting rods 27 respectively, the bottoms of the two connecting rods 27 are both articulated sliders 28, one side of the two sliders 28 is fixedly connected with a rack plate 29, and the teeth of the two rack plates 29 are respectively meshed with the teeth of the two internal gears 30.

[0048] During operation: when the filter plate 4 rises, the rack plate 29 is driven to rise through the connecting rod 27 and the slider 28. When the rack plate 29 rises, the internal gear 30 meshing with it is rotated, so that the stirring assembly can fully stir the wastewater and the reactant. The slider 28 is connected to the hinge seat 5 by a hinge, so that when the hinge seat 5 rotates and tilts, the slider 28 and the rack plate 29 connected at the bottom will not tilt.

[0049] like Figures 2 to 3 As shown, the inner side of the wastewater treatment box 1 is symmetrically provided with inner slide grooves 26 , and the hinge seat 2 6 , the hinge seat 1 5 and the slide block 28 are all slidably connected to the inner wall of the inner slide groove 26 .

[0050] During operation: through the inner slide groove 26, the hinge seat 2 6, the hinge seat 1 5 and the slider 28 can always be located in the inner wall of the inner slide groove 26 when entering the interior of the wastewater treatment box 1, so that the wastewater treatment box 1 and the filter plate 4 can always maintain a fitting relationship. Since the filter plate 4 rises from the wastewater, a certain buoyancy resistance will be generated. Through the sliding restriction, the hinge seat 1 5 will not be affected by the buoyancy and shake during the rising process.

[0051] Working process: First, the water inlet pipe 2 is connected to the wastewater outlet so that the wastewater enters the wastewater treatment tank 1, and the water outlet pipe 3 is connected to the wastewater next treatment device so that the wastewater is discharged from the wastewater treatment tank 1. When the wastewater enters the wastewater treatment tank 1, a reactant is added to the wastewater treatment tank 1 to mix with the wastewater, and the microorganisms present in the wastewater are treated, and the solid sediment will be filtered to the top of the filter plate 4, and then the motor 15 is started, and its output shaft will drive the driving gear 14 to rotate. When the driving gear 14 rotates, it will drive the transmission tooth chain 13 to transmit. When the transmission tooth chain 13 is driven When the transmission is in progress, the two driven gears 12 will be driven to rotate, and the two driven gears 12 will drive the rope winding shaft 9 to rotate through the two rotating rods 10. When the rope winding shaft 9 rotates, the tension rope 8 will be wound around the outer wall of the rope winding shaft 9, thereby pulling the filter plate 4 upward, so that the filter plate 4 can rise from the inside of the wastewater treatment tank 1 to the top of the wastewater treatment tank 1. The filter plate 4 can salvage the suspended matter in the wastewater during the rising process, and after rising to the top of the wastewater treatment tank 1, it is convenient for the staff to collect these debris, which is convenient for the subsequent use of the filter plate 4.

[0052] The pulling direction of the tension rope 8 is changed by movable pulley 16 and movable pulley 2 17. Movable pulley 2 17 is located directly above the rope ring 7, so that the filter plate 4 always maintains a vertical state during the ascending process, and has higher stability, and can accurately touch the tilting component when ascending. Movable pulley 16 is located directly above the rope winding shaft 9, so that the other end of the tension rope 8 can always be wound around the outer wall of the rope winding shaft 9.

[0053] Secondly, when the filter plate 4 rises, the rack plate 29 will be driven to rise through the connecting rod 27 and the slider 28. When the rack plate 29 rises, the internal gear 30 meshing with it will rotate. When the internal gear 30 rotates, it will drive the stirring rod 31 to rotate. When the stirring rod 31 rotates, the stirring blade 32 will stir the wastewater inside the wastewater treatment box 1, so that the added reactants and wastewater can fully react, ensuring that the reactants are fully in contact and react with the pollutants in the wastewater, thereby accelerating the removal or conversion process of the pollutants, and the slider 28 is connected to the hinge seat 5 by a hinge, so that when the hinge seat 5 rotates and tilts, the slider 28 and the rack plate 29 connected at the bottom will not tilt.

[0054] Then, since the two tilting seats 22 are fixedly mounted on the tilting surface of the right-angle platform 24, the tilting seats 22 always maintain a tilted state. During the rising process of the filter plate 4, the round block 20 will slowly enter the inner wall of the tilting seat 22, and when the round block 20 completely enters the inner wall of the tilting seat 22, when the round block 20 continues to rise, the shafts on both sides of the round block 20 will slide along the side slide grooves 23, and the round block 20 will slide along the inner wall of the tilting seat 22, so that the rotating rod 10 rotates a certain angle, and the limit block 21 can maintain stability during the sliding process. When the connecting rotating rod 19 drives the filter plate 4 to tilt, the wastewater retained on the surface of the filter plate 4 at this time Under the action of gravity, it will flow down quickly and return to the interior of the wastewater treatment box 1 without waiting for a long time to dry. When the shafts on both sides of the round block 20 slide along the side slide groove 23, the inclination angle of the filter plate 4 gradually increases, and according to actual conditions, the round block 20 can drive the filter plate 4 to tilt at an angle that is just enough to drain the water without affecting the falling of impurities. By tilting the filter plate 4, the wastewater can flow back from the surface of the filter plate 4 to the wastewater treatment box 1 more quickly and effectively, which contributes to the smoothness and efficiency of the overall treatment process, significantly reduces the time that the wastewater stays on the surface of the filter plate, and effectively reduces the phenomenon of slow drying.

[0055] Finally, when the filter plate 4 is tilted, the suspended matter and solid sediment on its surface will flow into the collection box 33 under the action of gravity, and the staff can knock on the surface of the filter plate 4 with tools so that these impurities can fall into the collection box 33 more completely, and then the collection box 33 can be removed to clean the impurities, and the filter screen 34 can be used to allow a portion of the water flowing into the collection box 33 to flow into the wastewater treatment tank 1 through the filter screen 34 in the tilted state.
