Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and in particular to a wastewater treatment and recovery device and method for chemical fiber production. Background Art

[0002] Wastewater treatment is the use of physical, chemical and biological methods to treat wastewater, purify wastewater, reduce pollution, and even achieve wastewater recovery and reuse, so as to make full use of water resources. Generally, when treating wastewater generated in the chemical fiber production process, it is necessary to first filter the impurities in the wastewater, and then flocculate, precipitate and add purification agents to the filtered wastewater, and achieve purification and recovery of the wastewater through multi-stage treatment of the discharged wastewater.

[0003] When multi-stage treatment of wastewater is carried out, large particles of impurities in the wastewater need to be filtered through filter plates. After a period of filtration, the filter plates will be blocked, so the staff needs to replace the filter plates. However, since the filter plates are installed in the filter bin, the degree of blockage of the filter plates cannot be clearly known. Therefore, when the filter plates are blocked, the filter plates cannot be replaced quickly, which will affect the treatment efficiency of the wastewater. After that, flocculants need to be added to the filtered wastewater for flocculation and sedimentation treatment. Since the wastewater is in a flowing state in the multi-stage treatment procedure, the mixing time of the filtered wastewater and the flocculant will be shorter, thereby affecting the subsequent sedimentation effect of the wastewater.

[0016] S2: The wastewater and flocculant are fully mixed through the diversion mixing element. The wastewater mixed with the flocculant will flow into the sedimentation tank through the water pump and pipeline for sedimentation treatment;

[0017] S3: The precipitated wastewater will flow into the sterilization barrel and then be discharged through the wastewater recovery pipe;

[0018] S4: As the amount of waste material accumulated on the top of the filter plate increases, some of the filter holes on the filter plate are blocked, so the amount of wastewater discharged from the wastewater discharge pipe into the wastewater purification barrel will be greater than the amount of wastewater discharged from the filter plate, so that part of the wastewater is still located above the filter plate.

[0019] S5: The staff can then close the valve and remove the filter plate for replacement.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. By setting the flow measuring piece, when most of the filter holes on the top of the filter plate are blocked, part of the wastewater will remain on the top of the filter plate. At this time, the floating block will rise relative to the first connecting chamber under the action of buoyancy, so that the oblique connecting plate squeezes the horizontal pin. When the plug hole is aligned with the longitudinal plug pin, the longitudinal plug pin is inserted into the plug hole. At this time, the buzzer will work, and the staff can close the valve. The wastewater remaining on the top of the filter plate will flow to the bottom of the filter plate through the filter holes on the filter plate, so that the second moving contact piece and the second static contact piece will contact again. At this time, the indicator light will work. When the buzzer and the indicator light work at the same time, the staff can remove the filter plate for replacement, so as to monitor the blockage degree of the filter plate and control the replacement time of the filter plate, thereby ensuring the utilization rate of the filter plate to the greatest extent and further improving the wastewater treatment efficiency.

[0022] 2. By setting the diversion mixing parts, the wastewater passing through the filter plate will fall into the collecting hopper and then be discharged through the bottom of the collecting hopper. The wastewater discharged through the bottom of the collecting hopper will impact one side of the paging plate, so that the paging plate can rotate relative to the buffer bin, so that the third transmission shaft can drive the rotating blades to rotate through the second bevel gear and the third bevel gear. At this time, the flocculant discharged from the flocculant discharge pipe will fall on the rotating blades in a rotating state through the diversion pipe, so that the flocculant is dispersed around the rotating blades. At the same time, as the wastewater increases, the wastewater passing through the buffer bin will accumulate inside the conical connecting bucket. After filling the inside of the conical connecting bucket, the wastewater will overflow from the top edge of the conical connecting bucket, so that the wastewater falls in an annular structure. At this time, the flocculant around the rotating blades will fully contact with the wastewater, thereby achieving full mixing of the flowing wastewater and the flocculant, further enhancing the equipment's wastewater treatment effect.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0034] See also Figures 1 to 8 In an embodiment of the present invention, a wastewater treatment and recovery device for chemical fiber production includes a mounting base 1, a wastewater purification barrel 2 is mounted on the top of the mounting base 1, a wastewater discharge pipe 3 is mounted on the top of the wastewater purification barrel 2, a valve 4 is arranged on the wastewater discharge pipe 3, a filter plate 801 extending to the inside of the wastewater purification barrel 2 is bolted to the outside of the wastewater purification barrel 2, a sedimentation barrel 5 arranged side by side with the wastewater purification barrel 2 is mounted on the top of the mounting base 1, a sterilization barrel 6 located on the side of the sedimentation barrel 5 away from the wastewater purification barrel 2 is mounted on the top of the mounting base 1, a wastewater recovery pipe 7 is arranged on the sterilization barrel 6, a flow measuring part located above the filter plate 801 is mounted inside the wastewater purification barrel 2, a flow dividing and mixing part located below the filter plate 801 is mounted inside the wastewater purification barrel 2, and the sedimentation barrel 5 and the wastewater purification barrel 2, and the sterilization barrel 6 and the sedimentation barrel 5 are connected through a water pump and a pipeline.

[0035] In this embodiment, the wastewater is first discharged into the wastewater purification barrel 2 through the wastewater discharge pipe 3. At this time, the wastewater entering the wastewater purification barrel 2 is filtered by the filter plate 801. During this process, the blockage degree of the filter plate 801 is detected by the flow measuring element. The wastewater filtered by the filter plate 801 will fall to the bottom of the wastewater purification barrel 2. At this time, the wastewater and the flocculant are fully mixed through the diversion mixing element. The wastewater mixed with the flocculant will flow into the sedimentation barrel 5 through the water pump and the pipeline for sedimentation treatment. The precipitated wastewater will flow into the sterilization barrel 6 and then be discharged through the wastewater recovery pipe 7. As the amount of waste material accumulated on the top of the filter plate 801 increases, some of the filter holes on the filter plate 801 are blocked. In this way, the amount of wastewater discharged from the wastewater discharge pipe 3 into the wastewater purification barrel 2 will be greater than the amount of wastewater discharged from the filter plate 801, so that part of the wastewater is still located above the filter plate 801. At this time, the flow measuring piece is operating, and the staff can close the valve 4 and then remove the filter plate 801 for replacement.

[0036] Please refer to Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8The flow measuring device includes a first connecting chamber 803 installed on the top of the wastewater purification barrel 2 and arranged side by side with the wastewater discharge pipe 3, an indicator light 827 is installed on the top of the first connecting chamber 803, a second connecting chamber 822 is installed on the side of the first connecting chamber 803 away from the wastewater discharge pipe 3, a buzzer 825 is installed on the side of the second connecting chamber 822 away from the first connecting chamber 803, a baffle 804 located above the filter plate 801 is installed on the inner wall of the wastewater purification barrel 2, and the first connecting chamber 803 is provided with an indicator light 827. A movable rod 823 extending to the inside of the baffle 804 is inserted into the interior of the movable rod 823, a floating block 824 is installed at the bottom of the movable rod 823, an oblique connecting plate 829 located on the inside of the first connecting chamber 803 is installed on the top of the movable rod 823, and a transverse latch 836 extending to the inside of the first connecting chamber 803 and located above the oblique connecting plate 829 is inserted into the interior of the second connecting chamber 822, a plug hole 830 is opened on the transverse latch 836, and a plug hole 830 is provided on the end of the transverse latch 836 away from the first connecting chamber 803. A second return spring 834 connected to the inner wall of the second connection chamber 822, a first static contact piece 833 located above the second return spring 834 is installed on the inner wall of the second connection chamber 822, a first movable contact piece 835 located above the second return spring 834 and flush with the first static contact piece 833 is installed at one end of the transverse latch 836, a longitudinal latch 826 extending into the interior of the second connection chamber 822 and located above the transverse latch 836 is plugged into the top of the second connection chamber 822, and the longitudinal latch A first return spring 832 connected to the top of the second connecting bin 822 is provided on 826, a guide rod 831 located above the transverse latch 836 is installed on the top of the inner wall of the first connecting bin 803, a support frame 828 connected to the movable rod 823 is slidably connected to the guide rod 831, a second static contact piece 837 located on the inner side of the support frame 828 is installed at the bottom end of the guide rod 831, and a second movable contact piece 838 located above the second static contact piece 837 is installed on the inner side of the support frame 828.

[0037] In this embodiment, the wastewater discharged through the wastewater discharge pipe 3 will fall on the top of the filter plate 801, and then the wastewater will be filtered through the filter plate 801. As the amount of wastewater injected into the wastewater purification barrel 2 increases, the waste in the wastewater will accumulate on the top of the filter plate 801. As the waste accumulates, some of the filter holes on the top of the filter plate 801 are blocked by the waste. When most of the filter holes on the top of the filter plate 801 are blocked, the amount of wastewater discharged from the wastewater discharge pipe 3 into the wastewater purification barrel 2 will be greater than the amount of wastewater passing through the filter plate 801, which will cause some of the wastewater to remain on the filter plate. 801, as the level of the retained wastewater increases, the float block 824 will rise relative to the first connecting chamber 803 under the action of buoyancy, so that the inclined connecting plate 829 squeezes the transverse latch 836, so that the transverse latch 836 moves away from the first connecting chamber 803, and at the same time, the second movable contact piece 838 separates from the second static contact piece 837. When the socket 830 is aligned with the longitudinal latch 826, the longitudinal latch 826 will be inserted into the socket 830 under the action of the elastic restoring force of the first return spring 832, so as to position the transverse latch 836. At the same time, the first movable contact piece 838 is 835 contacts the first static contact piece 833, thereby making the buzzer 825 operate. When the buzzer 825 operates, the staff can close the valve 4, and the wastewater remaining above the filter plate 801 will flow to the bottom of the filter plate 801 through the filter holes on the filter plate 801. In this process, the movable rod 823 moves downward relative to the first connecting chamber 803 as the wastewater level above the filter plate 801 decreases, thereby making the second movable contact piece 838 contact the second static contact piece 837 again. At this time, the indicator light 827 operates. When the buzzer 825 and the indicator light 827 operate at the same time, the staff can close the valve 4. The staff can remove the filter plate 801 for replacement, thereby monitoring the blockage degree of the filter plate 801 and controlling the replacement timing of the filter plate 801, thereby ensuring the utilization rate of the filter plate 801 to the greatest extent and further improving the wastewater treatment efficiency. After the filter plate 801 is replaced, the longitudinal latch 826 is pulled to separate the longitudinal latch 826 from the socket 830, so that the transverse latch 836 moves to the top of the oblique connecting plate 829 under the action of the elastic restoring force of the second return spring 834. At this time, the buzzer 825 stops working and only the indicator light 827 is in operation.

[0038] Please refer to Figure 7 , Figure 8 The second static contact piece 837 and the first moving contact piece 835 are both electrically connected to the external power supply through wires, the second moving contact piece 838 is electrically connected to the indicator light 827 through a wire, and the first static contact piece 833 is electrically connected to the buzzer 825 through a wire.

[0039] In this embodiment: by setting this structure, the buzzer 825 operates when the first moving contact piece 835 contacts the first stationary contact piece 833, and the indicator light 827 operates when the second stationary contact piece 837 contacts the second moving contact piece 838, thereby controlling the operating timing of the indicator light 827 and the buzzer 825.

[0040] Please refer to Figure 7 The bottom end of the longitudinal latch 826 and the end of the transverse latch 836 away from the second return spring 834 are both rotatably connected to balls via a rotating shaft, and the diameter of the hole 830 is equal to the bottom of the longitudinal latch 826.

[0041] In this embodiment: this structure is provided to reduce the friction between the transverse pin 836 and the diagonal connecting plate 829, and between the longitudinal pin 826 and the transverse pin 836, while also increasing the stability of the transverse pin 836 after the bottom of the longitudinal pin 826 is inserted into the insertion hole 830.

[0042] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5The diversion mixed liquid component includes a collecting hopper 805 installed on the inner wall of the wastewater purification barrel 2 and located below the filter plate 801, a buffer bin 809 is installed at the bottom of the collecting hopper 805, a conical connecting bucket 807 is installed at the bottom of the buffer bin 809, a flocculant discharge pipe 802 extending to the bottom of the conical connecting bucket 807 is installed on the outside of the wastewater purification barrel 2, a paging plate 819 is rotatably connected to the inner side of the buffer bin 809 through a rotating shaft, and one end of the rotating shaft connecting the paging plate 819 and the buffer bin 809 is provided with a first transmission spur gear 817 located on the outside of the buffer bin 809, a C-type connecting frame 808 is installed on the outer wall of the buffer bin 809, and a second transmission shaft 810 is arranged on the top of the C-type connecting frame 808, and a second transmission shaft 818 meshing with the first transmission spur gear 817 is installed at one end of the second transmission shaft 810 close to the buffer bin 809, and the second transmission shaft 810 is away from the second transmission shaft 810. A fourth bevel gear 821 is installed at one end of the spur gear 818, and the side of the C-type connecting frame 808 away from the buffer bin 809 is rotatably connected to the first transmission shaft 806 through a bearing, and the inner side of the C-type connecting frame 808 is rotatably connected to the third transmission shaft 814 through a bearing, and second bevel gears 816 are installed at both ends of the third transmission shaft 814, and first bevel gears 815 are installed at both ends of the first transmission shaft 806. The first bevel gears 815 at both ends of the first transmission shaft 806 are respectively meshed with the fourth bevel gear 821 and the second bevel gear 816, and a diverter pipe 811 located below the conical connecting bucket 807 is installed at the bottom end of the flocculant discharge pipe 802, and a positioning rod 812 is installed at the bottom of the diverter pipe 811, and a rotating blade 813 is rotatably connected to the positioning rod 812 through a bearing, and a third bevel gear 820 meshing with the second bevel gear 816 is installed at the bottom end of the rotating blade 813.

[0043] In this embodiment, the wastewater passing through the filter plate 801 will fall into the collecting hopper 805, and then be discharged from the bottom of the collecting hopper 805. The wastewater discharged from the bottom of the collecting hopper 805 will impact one side of the paging plate 819, so that the paging plate 819 can rotate relative to the buffer bin 809. At this time, the paging plate 819 will drive the third transmission shaft 814 to rotate through the first transmission spur gear 817, the second transmission spur gear 818, the second transmission shaft 810, the fourth bevel gear 821, the first transmission shaft 806, the first bevel gear 815, and the second bevel gear 816, so that the third transmission shaft 814 can drive the second bevel gear 816 and the third bevel gear 820 to drive the third transmission shaft 814 to rotate. The rotating blades 813 rotate, and the flocculant discharged from the flocculant discharge pipe 802 will fall on the rotating blades 813 in a rotating state through the diversion pipe 811, so that the flocculant is dispersed around the rotating blades 813. At the same time, as the amount of wastewater increases, the wastewater passing through the buffer bin 809 will accumulate inside the conical connecting bucket 807. After the inside of the conical connecting bucket 807 is filled, the wastewater will overflow from the top edge of the conical connecting bucket 807, so that the wastewater falls in an annular structure. At this time, the flocculant around the rotating blades 813 will be in full contact with the wastewater, thereby achieving full mixing of the flowing wastewater and the flocculant, further enhancing the equipment's treatment effect on wastewater.

[0044] Please refer to Figure 4 The buffer bin 809 is a hollow bottomless rectangular structure. The top of the buffer bin 809 is provided with a through hole that fits with the bottom of the collecting hopper 805. The diameter of the top of the conical connecting bucket 807 is greater than the length and width of the bottom cross-section of the buffer bin 809.

[0045] In this embodiment, this structure is provided to make all wastewater discharged from the buffer bin 809 fall into the inner side of the conical connecting bucket 807 , thereby preventing wastewater discharged from the buffer bin 809 from being discharged from around the conical connecting bucket 807 .

[0046] Please refer to Figure 4 , the vertical center axis of the paging plate 819 and the vertical center axis of the collecting hopper 805 are in a misaligned state.

[0047] In this embodiment: by setting this structure, the waste water discharged from the bottom of the collecting hopper 805 can push one side of the paging plate 819 when falling, so that the paging plate 819 can rotate as the waste water is discharged from the collecting hopper 805.

[0048] Please refer to Figure 2 The diameter of the top of the collecting hopper 805 is equal to the diameter of the inner wall of the wastewater purification barrel 2.

[0049] In this embodiment, by setting this structure, the waste water discharged from the filter plate 801 is discharged through the bottom of the collecting hopper 805.

[0050] Please refer to Figure 7 The horizontal height of the oblique connecting plate 829 close to the second connecting chamber 822 is lower than the horizontal height of the oblique connecting plate 829 away from the second connecting chamber 822.

[0051] In this embodiment, this structure is provided to enable the insertion hole 830 to move in a direction away from the first connection compartment 803 when the oblique connecting plate 829 moves upward.

[0052] In combination with the above-mentioned wastewater treatment and recovery device for chemical fiber production, a method for treating and recovering wastewater for chemical fiber production is provided, which specifically includes the following steps:

[0053] S1: First, the wastewater is discharged into the wastewater purification barrel 2 through the wastewater discharge pipe 3. At this time, the wastewater entering the wastewater purification barrel 2 is filtered by the filter plate 801, and the indicator light 827 is in operation;

[0054] S2: As the amount of wastewater injected into the wastewater purification barrel 2 increases, waste materials in the wastewater will accumulate on the top of the filter plate 801. As the waste materials accumulate, part of the filter holes on the top of the filter plate 801 are blocked by the waste materials.

[0055] S3: The wastewater passing through the filter plate 801 will fall into the collecting hopper 805, and then be discharged from the bottom of the collecting hopper 805. The wastewater discharged from the bottom of the collecting hopper 805 will impact one side of the paging plate 819, so that the paging plate 819 can rotate relative to the buffer bin 809. At this time, the paging plate 819 will drive the third transmission shaft 814 to rotate through the first transmission spur gear 817, the second transmission spur gear 818, the second transmission shaft 810, the fourth bevel gear 821, the first transmission shaft 806, the first bevel gear 815, and the second bevel gear 816, so that the third transmission shaft 814 can rotate through the second bevel gear 816 and the third bevel gear 820. The rotating blades 813 rotate, and the flocculant discharged from the flocculant discharge pipe 802 will fall on the rotating blades 813 in a rotating state through the diverter pipe 811, so that the flocculant is dispersed around the rotating blades 813. At the same time, as the wastewater increases, the wastewater passing through the buffer bin 809 will accumulate inside the conical connecting bucket 807. After the conical connecting bucket 807 is filled, the wastewater will overflow from the top edge of the conical connecting bucket 807, so that the wastewater falls in an annular structure. At this time, the flocculant around the rotating blades 813 will fully contact with the wastewater, thereby achieving full mixing of the flowing wastewater and the flocculant, further enhancing the wastewater treatment effect of the equipment;

[0056] S4: The wastewater mixed with the flocculant will flow into the sedimentation tank 5 through the water pump and the pipeline for sedimentation treatment;

[0057] S5: The precipitated wastewater flows into the sterilization barrel 6 and is then discharged through the wastewater recovery pipe 7;

[0058] S6: When most of the filter holes on the top of the filter plate 801 are blocked, the amount of wastewater discharged from the wastewater discharge pipe 3 into the wastewater purification barrel 2 will be greater than the amount of wastewater passing through the filter plate 801, which will cause part of the wastewater to remain on the top of the filter plate 801. As the water level of the retained wastewater increases, the floating block 824 will rise relative to the first connecting chamber 803 under the action of buoyancy, so that the inclined connecting plate 829 squeezes the horizontal pin 836, so that the horizontal pin 836 moves away from the first connecting chamber. The first movable contact piece 835 is moved in the direction of the receiving bin 803, and the second movable contact piece 838 is separated from the second static contact piece 837. When the insertion hole 830 is aligned with the longitudinal latch 826, the longitudinal latch 826 is inserted into the insertion hole 830 under the elastic restoring force of the first return spring 832, so as to position the transverse latch 836. At the same time, the first movable contact piece 835 is in contact with the first static contact piece 833, so as to operate the buzzer 825. When the buzzer 825 is operating, the staff can close the valve 4.

[0059] S7: At the same time, the wastewater remaining on the filter plate 801 will flow to the bottom of the filter plate 801 through the filter holes on the filter plate 801. During this process, the movable rod 823 moves downward relative to the first connecting chamber 803 as the wastewater level above the filter plate 801 decreases, so that the second movable contact piece 838 and the second static contact piece 837 are in contact again. At this time, the indicator light 827 operates. When the buzzer 825 and the indicator light 827 operate at the same time, the staff can remove the filter plate 801 for replacement;

[0060] S8: After the filter plate 801 is replaced, the longitudinal pin 826 is pulled to separate the longitudinal pin 826 from the socket 830, so that the transverse pin 836 moves to the top of the diagonal connecting plate 829 under the elastic restoring force of the second return spring 834. At this time, the buzzer 825 stops working and only the indicator light 827 is in operation.

[0061] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
