Description

Technical Field

[0001] The present invention relates to the technical field of printing and dyeing, and in particular to a waste dye liquor recovery system. Background Art

[0002] The waste dye liquor recovery system is a device that can recycle and reuse waste dye liquor and make the waste water meet the reuse standards.

[0003] Existing waste dye liquor recovery systems typically pass the waste dye liquor through activated carbon-filled columns, allowing the activated carbon to adsorb the waste dye molecules, so that the wastewater meets the reuse standards. At the same time, the activated carbon particles or powder that have adsorbed the waste dye can be regenerated through high-temperature calcination and other methods to recover the dye and realize the recycling and reuse of the waste dye liquor. However, since the activated carbon-filled columns are directly connected to the waste liquid pipeline, the replacement of the activated carbon-filled columns and the recovery of the activated carbon after dye adsorption require a long time, which is relatively inconvenient to operate. Summary of the Invention

[0004] The present invention aims to provide a waste dye liquor recovery system, which has the effect of improving the convenience of waste dye liquor recovery operation.

[0005] The above-mentioned technical objectives of the present invention are achieved through the following technical solutions: it includes a recovery pool, a recovery wall and a liquid inlet pipe connected to the bottom of the recovery pool, the recovery pool is connected to a liquid outlet pipe at one end away from the liquid inlet pipe, a recovery component for recovering waste dye liquid is movably arranged in the recovery pool, the recovery component includes a plurality of recovery frames with rectangular cross-sections and filter holes evenly arranged on the recovery frames, and there is a set distance between adjacent recovery frames, the bottom of the recovery frame can be movably attached to the inner wall of the recovery pool, the recovery frame is filled with activated carbon particles, and a plurality of partitions are vertically arranged in the recovery pool to cooperate with the recovery frames, and the two sides of the partition are movably attached to two adjacent recovery frames respectively, one end of the partition is fixedly connected to the inner wall of the recovery pool, and the other end of the partition is at a set distance from the inner wall of the recovery pool, and a serpentine recovery channel is formed between the plurality of partitions and the inner wall of the recovery pool.

[0006] By setting up a recovery pool, recovery components, etc., when it is necessary to recover waste dye liquor, the liquid inlet pipe is opened, so that the waste dye liquor enters the recovery pool through the liquid inlet pipe. After entering the recovery pool, the waste dye liquor flows along the serpentine recovery channel formed by the partition plate and the recovery pool. During the flowing process, it sequentially enters the recovery frame through the filter holes. The activated carbon particles in the recovery frame adsorb the dyes in the waste dye liquor. Then, the waste dye liquor flows out of the recovery frame through the filter holes. Through the adsorption of the activated carbon particles in multiple sequentially arranged recovery frames, the dye molecules in the waste dye liquor are removed, making the remaining waste liquid meet the reuse standard. Finally, the waste liquid flows out through the liquid outlet pipe for reuse. Therefore, through the serpentine recovery channel formed by the partition plate and the recovery pool, in cooperation with multiple recovery frames, the flowing path of the dye waste liquid in the recovery pool is greatly extended, thereby greatly increasing the contact time between the waste dye liquor and the activated carbon particles, improving the adsorption time of the activated carbon particles for the waste dye liquor, and enabling the remaining waste liquid to meet the reuse standard. At the same time, the recovery frame is movably connected to the recovery pool. When the activated carbon particles need to be transferred and replaced, only need to sequentially take out the recovery frames upward to recover and replace the activated carbon particles, which is simple and convenient to operate, and improves the convenience of the waste dye liquor recovery operation.

[0007] A further setting of the present invention is that: connecting plates are symmetrically arranged along the vertical direction at the top of the recovery component.

[0008] By setting up the connecting plates, multiple recovery frames are connected. When it is necessary to replace the activated carbon particles in the recovery frames, only need to lift and take out the whole recovery component upward, without having to sequentially take out multiple recovery frames, thereby further improving the convenience of the waste dye liquor recovery operation.

[0009] A further setting of the present invention is that: two groups of lifting ropes are arranged between the two connecting plates. A lifting rod that can cooperate with a hoisting trolley is movably arranged horizontally directly above the recovery component. Hoisting wheels that can cooperate with the lifting ropes are symmetrically arranged at both ends of the lifting rod.

[0010] By setting up the lifting ropes, lifting rod, etc., when it is necessary to take out the recovery component, connect the lifting hook of the hoisting trolley to the lifting rod, and connect the two groups of lifting ropes to the two hoisting wheels respectively, then the hoisting trolley can be driven (it should be noted that) to move upward to lift the whole recovery component for transfer (it should be noted that the hoisting trolley is a prior art, so the hoisting trolley is not drawn in the drawings, which does not affect the understanding of the actually protected technical scope of the present solution by those skilled in the art); setting the lifting rod and hoisting wheels can, compared with the hoisting trolley directly hoisting the lifting ropes, increase the stability of the whole recovery component during the hoisting process through the horizontally arranged lifting rod, thereby improving the safety of the process of hoisting the recovery component.

[0011] A further setting of the present invention is that: clamping rings are symmetrically arranged at the bottom end of the recovery member, and a blanking member for transferring the activated carbon particles and capable of cooperating with the clamping rings is arranged on one side of the recovery wall.

[0012] A further setting of the present invention is that: the blanking member includes first blanking rods which are arc-shaped and symmetrically arranged in the horizontal direction and second blanking rods which are arranged vertically upward at the ends of the first blanking rods, and the two clamping rings can be respectively clamped on the two second blanking rods.

[0013] By arranging the clamping rings and the first blanking rods, etc., when it is necessary to recover and replace the activated carbon particles in the recovery box, first lift the recovery box by a hoist, then horizontally move it to one side of the recovery wall, and then the hoisting crane moves the hoisting rod downward, so that the recovery member moves downward. In this process, the clamping rings on one side of the recovery member are respectively clamped on the two second blanking rods, and then the clamping rings abut against the first blanking rods. The hoisting rod continues to descend, and the whole recovery member abuts against the first blanking rods through the clamping rings. Since one side of the recovery member abuts against the first blanking rods through the clamping rings, the other side of the recovery member turns downward, making the opening of the recovery member face downward. Workers can directly transfer the activated carbon particles in the recovery box through tools. Then, the activated carbon particles adsorbed with dyes can be regenerated, the dyes can be recovered, and at the same time, new activated carbon particles are filled into the recovery box. Then, drive the hoisting crane to rise, drive the hoisting rod and the recovery member to rise until the recovery member is separated from the second blanking rod, then drive the hoisting rod to horizontally move to directly below the recovery box, drive the hoisting rod to move downward until the recovery box fits against the partition and descends to abut against the bottom of the recovery pool, and then the waste dye liquor can be continuously recovered; Therefore, by arranging the clamping rings and the first blanking rods, etc., and cooperating with each other, the hoisting crane can directly hoist the recovery member to be clamped on the first blanking rod, realizing the automatic downward turning of the recovery box, facilitating workers to transfer the activated carbon particles therein, thereby facilitating the recovery and replacement of the activated carbon particles in the recovery box and improving the convenience of the waste dye liquor recovery operation.

[0014] A further setting of the present invention is that: a limiting plate is horizontally arranged at the top end of the recovery box, and adjacent two limiting plates are fixedly connected, and the bottom end of the limiting plate can abut against the top end of the partition.

[0015] By arranging the limiting plates, the connection between adjacent recovery boxes is further strengthened, and the stability during the movement of the whole recovery member is improved.

[0016] A further setting of the present invention is that: a water quality monitor is arranged at one end of the liquid outlet pipe close to the recovery pool, a reflux pipe is communicated between the liquid outlet pipe and the liquid inlet pipe, and a reflux pump is arranged on the reflux pipe.

[0017] By setting up a water quality detector, a reflux pipe, etc., the treated wastewater flowing out of the recovery tank is first detected by the water quality monitor. When the detection is unqualified, the control valves of the liquid outlet pipe and the liquid inlet pipe are closed, and the control valve of the reflux pipe is opened. The reflux pump drives the wastewater to flow back to the end of the water inlet pipe, and then enters the recovery tank from the water inlet pipe for recycling and adsorption again. This cycle repeats until the detection is qualified, and then the control valve of the liquid outlet pipe is driven to open. The qualified treated wastewater is reused through the liquid outlet pipe; by setting up a reflux pipe, etc., the dyeing wastewater can be recycled and adsorbed multiple times in the recovery tank, ensuring that the wastewater finally flowing out of the liquid outlet pipe meets the reuse standard. Therefore, even under the condition of limited recovery tank and recovery channel, it can ensure that the requirements of recovery and reuse are met through multiple adsorption and recovery, greatly increasing the applicable range of the waste dye recovery system.

[0018] The further setting of the present invention is: a guiding member matching with the recovery member is vertically arranged at the top end of the recovery tank. The guiding member includes four first guiding blocks with an L-shaped cross-section vertically arranged at the top end of the recovery tank, and the four corners of the recovery member can be respectively and movably attached to the inner sides of the four first guiding blocks.

[0019] The further setting of the present invention is: a second guiding block is arranged at the top end of the first guiding block, and the projected area of the top end of the second guiding block in the vertical direction is larger than the projected area of the bottom end of the second guiding block in the vertical direction.

[0020] By setting the first guiding block and the second guiding block, when hoisting the recovery member downward to the recovery tank, it is convenient to determine the descending position that the hoisting crane needs to align with when hoisting the recovery member downward through the guidance of the second guiding block, and then ensure the accurate connection between the recovery frame and the partition through the first guiding block, so as to facilitate the operator to control the hoisting crane to achieve the accurate connection between the recovery member and the recovery tank.

[0021] The further setting of the present invention is: an annular hoisting ring is arranged at the top end of the hoisting rod.

[0022] By setting the hoisting ring, the hook of the hoisting crane is connected to the hoisting rod through the hoisting ring. Through the limit of the hoisting ring, the shaking of the hoisting rod during hoisting is reduced, thereby improving the stability of the recovery member during hoisting.

[0023] The beneficial effects of the present invention are:

[0024] 1. By setting up a serpentine recovery channel formed between the partition board and the recovery pool, and cooperating with multiple recovery frames at the same time, the flow path of the dye waste liquid in the recovery pool is greatly extended, thereby greatly increasing the contact time between the waste dye liquid and the activated carbon particles, improving the adsorption time of the activated carbon particles for the waste dye liquid, so that the remaining waste liquid meets the standard for reuse; at the same time, the recovery frame is movably connected to the recovery pool. When the activated carbon particles need to be transferred and replaced, only need to take out the recovery frames upward in turn to recover and replace the activated carbon particles, which is simple and convenient to operate, and improves the convenience of the waste dye liquid recovery operation.

[0025] 2. By setting up snap rings and the first pouring rod, etc., and cooperating with each other, the hoisting crane can directly hoist the recovery part to be clamped on the first pouring rod, realizing the automatic downward turnover of the recovery frame, facilitating the workers to transfer the activated carbon particles therein, thus facilitating the recovery and replacement of the activated carbon particles in the recovery frame, and improving the convenience of the waste dye liquid recovery operation.

[0026] 3. By setting up a reflux pipe, etc., the dye wastewater can be recycled and adsorbed multiple times in the recovery pool, ensuring that the wastewater finally flowing out from the liquid outlet pipe meets the reuse standard. Therefore, even under the condition of limited recovery pool and recovery channel, it can also ensure that the requirements of recovery and reuse are met through multiple adsorption and recovery, greatly increasing the application range of the waste dye liquid recovery system.

[0033] The present invention provides a waste dye liquor recovery system, as Figures 1 to 3 shown, including a recovery pool 1, a recovery wall 2, and a liquid inlet pipe 3 connected to the bottom of the recovery pool 1. An outlet pipe 4 is connected to one end of the recovery pool 1 away from the liquid inlet pipe 3. A recovery member 5 for recovering waste dye liquor is movably arranged in the recovery pool 1. The recovery member 5 includes a plurality of recovery frames 5a with a rectangular cross-section and filter holes 5b uniformly arranged on the recovery frames 5a. There is a set distance between adjacent recovery frames 5a. The bottom of the recovery frame 5a can be movably attached to the inner wall of the recovery pool 1. Activated carbon particles are filled in the recovery frame 5a. A plurality of partition boards 6 matching the recovery frames 5a are vertically arranged in the recovery pool 1. Both sides of the partition board 6 are movably attached to two adjacent recovery frames 5a respectively. One end of the partition board 6 is fixedly connected to the inner wall of the recovery pool 1, and there is a set distance between the other end of the partition board 6 and the inner wall of the recovery pool 1. A serpentine recovery channel 7 is formed between a plurality of partition boards 6 and the inner wall of the recovery pool 1.

[0034] Further, connecting plates 8 are symmetrically arranged along the vertical direction at the top end of the recovery member 5.

[0035] Further, two groups of lifting ropes 9 are arranged between the two connecting plates 8. A lifting rod 10 that can cooperate with a hoisting crane is movably arranged horizontally directly above the recovery member 5. Lifting wheels 11 that can cooperate with the lifting ropes 9 are symmetrically arranged at both ends of the lifting rod 10.

[0036] Further, snap rings 12 are symmetrically arranged at the bottom end of the recovery member 5. A tipping member 13 for transferring the activated carbon particles and capable of cooperating with the snap rings 12 is arranged on one side of the recovery wall 2.

[0037] Further, the emptying member 13 includes first emptying rods 13a that are arc-shaped and symmetrically arranged in the horizontal direction, and second emptying rods 13b that are vertically upwardly arranged at the ends of the first emptying rods 13a. The two snap rings 12 can be respectively snapped onto the two second emptying rods 13b.

[0038] Further, a limiting plate 14 is horizontally arranged at the top end of the recovery box 5a. Adjacent two limiting plates 14 are fixedly connected, and the bottom end of the limiting plate 14 can abut against the top end of the partition plate 6.

[0039] Further, a water quality monitor 15 is arranged at one end of the liquid outlet pipe 4 close to the recovery pool 1. A return pipe 16 is communicatively arranged between the liquid outlet pipe 4 and the liquid inlet pipe 3, and a return pump 17 is arranged on the return pipe 16.

[0040] Further, a guiding member that cooperates with the recovery member 5 is vertically arranged at the top end of the recovery pool 1. The guiding member includes four first guiding blocks 18 with an L-shaped cross-section that are vertically arranged at the top end of the recovery pool 1. The four corners of the recovery member 5 can respectively be movably attached to the inner sides of the four first guiding blocks 18.

[0041] Further, a second guiding block 19 is arranged at the top end of the first guiding block 18. The projected area of the top end of the second guiding block 19 in the vertical direction is larger than the projected area of the bottom end of the second guiding block 19 in the vertical direction.

[0042] Further, a ring-shaped lifting ring 20 is arranged at the top end of the lifting rod 10.

[0043] When it is necessary to recycle the waste dye liquor, the liquid inlet pipe 3 is opened, so that the waste dye liquor enters the recovery tank 1 through the liquid inlet pipe 3. After entering the recovery tank 1, the waste dye liquor flows along the serpentine recovery channel 7 formed by the partition plate 6 and the recovery tank 1. During the flowing process, it sequentially enters the recovery frame 5a through the filter holes 5b. The activated carbon particles in the recovery frame 5a adsorb the dye in the waste dye liquor. Then the waste dye liquor flows out of the recovery frame 5a through the filter holes 5b again. Through the adsorption of the activated carbon particles in a plurality of sequentially arranged recovery frames 5a, the dye molecules in it are removed. Then the treated waste water flowing out of the recovery tank 1 is first detected by the water quality monitor 15. When the detection is unqualified, the control valves of the liquid outlet pipe 4 and the liquid inlet pipe 3 are closed, and the control valve of the driving return pipe 16 is opened. The return pump 17 drives the waste water to flow back to the end of the water inlet pipe. Then it enters the recovery tank 1 from the water inlet pipe and is recycled and adsorbed again. This process is repeated until the detection is qualified, and then the control valve of the liquid outlet pipe 4 is driven to open. The treated qualified waste water is reused through the liquid outlet pipe 4. Then when it is necessary to recycle and replace the activated carbon particles in the recovery frame 5a, first lift the recovery frame 5a, then horizontally move it to one side of the recovery wall 2, and then the overhead crane moves the lifting rod 10 downward, so that the recovery part 5 moves downward. During this process, the snap rings 12 on one side of the recovery part 5 are respectively engaged with the two second blanking rods 13b. Then the snap ring 12 abuts against the first blanking rod 13a. The lifting rod 10 continues to descend, and the whole recovery part 5 abuts against the first blanking rod 13a through the snap ring 12. Since one side of the recovery part 5 abuts against the first blanking rod 13a through the snap ring 12, the other side of the recovery part 5 turns downward, so that the opening of the recovery part 5 faces downward. Workers can directly transfer the activated carbon particles in the recovery frame 5a through tools. Then the activated carbon particles adsorbed with dye can be regenerated, the dye can be recycled, and at the same time new activated carbon particles are filled into the recovery frame 5a. Then drive the overhead crane to rise, drive the lifting rod 10 and the recovery part 5 to rise until the recovery part 5 is separated from the second blanking rod 13b. Then drive the lifting rod 10 to horizontally move to directly below the recovery frame 5a, and drive the lifting rod 10 to move downward until the recovery frame 5a fits against the partition plate 6 and descends to abut against the bottom of the recovery tank 1. Then the waste dye liquor can be recycled continuously; Therefore, through the serpentine recovery channel 7 formed by the partition plate 6 and the recovery tank 1, and in cooperation with a plurality of recovery frames 5a, the flow path of the dye waste liquid in the recovery tank 1 is greatly extended, so that the contact time between the waste dye liquor and the activated carbon particles is greatly increased, the adsorption time of the activated carbon particles to the waste dye liquor is improved, and the remaining waste liquid meets the standard for reuse; At the same time, the recovery frame 5a is movably connected to the recovery tank 1. When the activated carbon particles need to be transferred and replaced, only the recovery frame 5a needs to be taken out upward in sequence to recycle and replace the activated carbon particles. The operation is simple and convenient, which improves the convenience of the waste dye liquor recovery operation.

[0044] By setting up the connecting plate 8, multiple recovery boxes 5a are connected. When it is necessary to replace the activated carbon particles in the recovery box 5a, the entire recovery component 5 can be lifted upward and removed, without the need to remove multiple recovery boxes 5a one by one, thus further improving the convenience of the waste dye liquor recovery operation.

[0045] By setting up the lifting ropes 9, lifting rods 10, etc., when it is necessary to remove the recovery component 5, connect the lifting hook of the overhead crane to the lifting rod 10, and connect the two groups of lifting ropes 9 to the two lifting wheels 11 respectively, then the overhead crane (it should be noted that) can be driven to move upward to lift the entire recovery component 5 for transfer (it should be noted that the overhead crane is a prior art, so the overhead crane is not drawn in the attached drawings, which does not affect the understanding of the actual protected technical scope of this solution by those skilled in the art); setting the lifting rod 10 and the lifting wheel 11 can, compared with the overhead crane directly lifting the lifting rope 9, increase the stability of the overall recovery component 5 during the lifting process through the horizontally arranged lifting rod 10, thus improving the safety of the process of lifting the recovery component 5.

[0046] By setting up the snap ring 12 and the first tipping rod 13a, etc., and cooperating with each other, the overhead crane can directly lift the recovery component 5 to be clamped on the first tipping rod 13a, realizing the automatic downward tipping of the recovery box 5a, which is convenient for workers to transfer the activated carbon particles therein, thus facilitating the recovery and replacement of the activated carbon particles in the recovery box 5a and improving the convenience of the waste dye liquor recovery operation.

[0047] By setting up the limiting plate 14, the connection between adjacent recovery boxes 5a is further strengthened, and the stability during the movement of the entire recovery component 5 is improved.

[0048] By setting up the return pipe 16, etc., the dye liquor wastewater can be recycled and adsorbed multiple times in the recovery tank 1, ensuring that the wastewater finally flowing out from the outlet pipe 4 meets the standard of reuse. Thus, even under the limited conditions of the recovery tank 1 and the recovery channel 7, it can be ensured that the requirements of recovery and reuse are met through multiple adsorption recoveries, greatly increasing the applicable range of the waste dye liquor recovery system.

[0049] By setting up the first guiding block 18 and the second guiding block 19, when the recovery component 5 is lifted downward to the recovery tank 1, the second guiding block 19 is used to facilitate determining the descending position that the overhead crane needs to align with when lifting the recovery component 5 downward, and then the first guiding block 18 is used to ensure that an accurate connection can be made between the recovery box 5a and the partition plate 6, thus facilitating the operator to control the overhead crane to achieve an accurate connection between the recovery component 5 and the recovery tank 1.

[0050] By setting the lifting ring 20, the hook of the overhead crane is connected to the lifting rod 10 through the lifting ring 20. Through the limit of the lifting ring 20, the sway of the lifting rod 10 during the lifting process is reduced, thereby improving the stability of the recovered part 5 during the lifting process.

[0051] It should be noted that the various embodiments in this specification are described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other.

[0052] The above description is only a description of the preferred embodiments of the present invention, and does not limit the scope of the present invention in any way. Any changes and modifications made by those of ordinary skill in the art of the present invention based on the above disclosure shall fall within the protection scope of the claims.
