Description

Technical Field

[0001] This invention relates to the field of dyeing wastewater treatment, and more particularly to a device for treating dyeing wastewater from chemical fiber fabrics. Background Technology

[0002] The dyeing and printing processes in the textile industry produce a large volume of wastewater with high color intensity and complex composition. The wastewater contains fuels, slurries, auxiliaries, acids, alkalis, fiber impurities, and various inorganic salts. In the process of purifying the wastewater, wastewater decolorizing agents are usually added. The wastewater decolorizing agents will flocculate the impurities in the wastewater and remove the pigments. The flocculated matter usually settles to the bottom of the wastewater by gravity, and the upper layer of liquid in the wastewater will be clean and clear.

[0003] For example, the invention patent with publication number CN118598234B discloses a fabric dyeing wastewater recycling and treatment device, including a reaction tank. The top of the reaction tank is provided with a top cover. Above the top cover are multiple storage cylinders for holding chemicals. Below the storage cylinders are multiple corrugated pipes for discharging materials. Below the multiple storage cylinders are dosing devices. A locking mechanism is provided between the multiple storage cylinders and the dosing devices. A swing mechanism is provided between the top cover and the dosing devices.

[0004] As can be seen from the above, in the prior art, in the process of treating dye wastewater, it is necessary to add decolorizing agent and flocculant to the wastewater, and stir in the reaction tank to make the decolorizing agent and flocculant react fully with the wastewater. Then, stop stirring, let the wastewater stand, and let the impurities precipitate and settle. Then, discharge the supernatant of the wastewater, and finally discharge the impurities at the bottom.

[0005] The above solution still has the following drawbacks: since the impurities that precipitate out after the wastewater is left to stand usually appear in the form of flocculent matter, which contains a large amount of wastewater, when the flocculent matter that has settled to the bottom is discharged, a large amount of wastewater will be discharged at the same time, which will require secondary treatment and thus increase the difficulty of wastewater treatment.

[0043] Compared with the prior art, the present invention has the following beneficial effects:

[0044] I. This invention, by setting up a rotatable inner shell, a drain pipe, a sealing block, a pressing block, and a filter block, allows flocculent matter in the wastewater to remain in the drain pipe during the drainage process. Then, the pressing block and the filter block squeeze each other to complete the dehydration of the flocculent matter, reducing the amount of wastewater residue in the flocculent matter. No secondary treatment is required, thereby reducing the difficulty of treating dyeing wastewater.

[0045] Second, by setting up an annular plate and a scraper, the annular plate cannot rotate during the rotation of the inner shell, thereby causing relative movement between the scraper and the inner wall of the inner shell. This facilitates the scraping off of flocculent material attached to the inner wall of the inner shell. When the drain pipe moves to the scraper, under centrifugal force, the flocculent material at the scraper enters the drain pipe, collecting as much flocculent sediment as possible in the inner shell and reducing the residue of flocculent sediment in the inner shell.

[0046] Third, this invention, by setting up a filter screen and an arc-shaped pressing block, causes the filter screen to deform as the pressing block approaches and squeezes it. The two connecting plates then move closer together, and the third spring is stretched and generates elastic force, thereby increasing the contact area between the arc-shaped pressing block and the filter screen. This facilitates the thorough squeezing and dewatering of the flocculent precipitate. When the pressing block moves away from the filter screen, the elastic force of the third spring causes the two connecting plates to reset the filter screen. At the moment the filter screen resets, the waste residue attached to it is shaken off, thus quickly detaching and reducing residue residue on the filter screen, thereby reducing clogging.

Detailed Implementation

[0057] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0058] like Figures 1 to 9 The device for treating wastewater from dyeing synthetic fiber fabrics shown includes:

[0059] The outer shell 1 is rotatably connected to the inner shell 3. Several drain pipes 4 are fixedly connected to the bottom of the inner shell 3. A sealing block 6 is slidably connected inside the drain pipes 4. The sealing block 6 is slidably connected to the bottom of the inner shell 3. A first spring 7 is fixedly connected to the end of the sealing block 6. A pressure block 8 is fixedly connected to the end of the first spring 7.

[0060] A drainage chamber 101 is formed inside the outer casing 1, and a first annular sealing plate 102 is rotatably connected inside the drainage chamber 101.

[0061] Several connecting pipes 9 are fixedly connected to the first annular sealing plate 102 at the positions corresponding to the drain pipe 4. A filter block 10 is slidably connected inside the connecting pipe 9. A second spring 11 is fixedly connected between the filter block 10 and the connecting pipe 9. The end of the filter block 10 extends toward the end of the drain pipe 4 and contacts the end of the drain pipe 4.

[0062] The first pushing mechanism is used to move the sealing block 6.

[0063] Rotary drive mechanism, used to drive the inner shell 3 to rotate;

[0064] The second driving mechanism is used to move the filter block 10.

[0065] It also includes a water inlet pipe 2, the top of which passes through the outer shell 1 and is rotatably connected to the inner shell 3;

[0066] Specifically, in existing technologies, impurities precipitated after wastewater settle typically appear in the form of flocculent matter containing a large amount of wastewater. This means that discharging the settled flocculent matter often results in the simultaneous discharge of a large amount of wastewater, necessitating secondary treatment and increasing the difficulty of wastewater treatment. This technical solution can address the above problems, and the specific operation is as follows:

[0067] First, the mixture of wastewater, decolorizing agent and flocculant is injected into the inner shell 3 through the water inlet pipe 2. Then, it is stirred by the stirring mechanism. After stirring is completed, the sealing block 6 is moved together with the pressure block 8 by the first pushing mechanism. The pressure block 8 is disengaged from the drain pipe 4, and the seal on the drain pipe 4 is removed, so that the wastewater in the inner shell 3 is discharged through the drain pipe 4. After the sewage passes through the drain pipe 4, it will reach the filter block 10. The filter block 10 is used to filter the flocculent precipitate in the wastewater and make the flocculent precipitate deposit in the drain pipe 4.

[0068] After the pressure block 8 is removed from the drain pipe 4 to cancel the seal on the drain pipe 4, the rotary drive mechanism is activated. The rotary drive mechanism causes the inner shell 3 to rotate. Under the action of centrifugal force, the particles in the wastewater will move in the direction with a larger rotation radius and settle to the bottom, and finally enter the drain pipe 4. This helps to increase the settling speed of the particles in the wastewater. In addition, under the action of centrifugal force, the wastewater will pressurize the filter block 10, which helps to increase the wastewater discharge speed.

[0069] After the wastewater is discharged, the sealing block 6 moves the pressure block 8 through the pushing mechanism to reseal the drain pipe 4. During the movement of the sealing block 6 and the pressure block 8, a large amount of flocculent material is present in the drain pipe 4, which occupies the space of the drain pipe 4 and puts pressure on the pressure block 8 in the opposite direction, causing the first spring 7 to be compressed and deformed. Since the forces are mutual, the flocculent material in the drain pipe 4 will be compressed during the continuous movement of the sealing block 6 pushing the pressure block 8, and then the wastewater in the flocculent material will be squeezed out. The squeezed-out wastewater enters the drain chamber 101 through the filter block 10 and the connecting pipe 9. The wastewater in the drain chamber 101 is discharged through the external pipe.

[0070] After extrusion, the filter block 10 is moved into the connecting pipe 9 by the second pushing mechanism, thereby creating a discharge space between the filter block 10 and the pressing block 8. Under the action of gravity, the waste residue between the filter block 10 and the pressing block 8 falls out and is discharged.

[0071] After completing the above operations, the filter block 10 is moved closer to the end of the drain pipe 4 and makes contact with the end of the drain pipe 4 by the second pushing mechanism. Then the sealing block 6 re-seals the drain pipe 4. Next, the wastewater to be treated is injected through the water inlet pipe 2, and then the wastewater treatment is carried out again according to the above operations.

[0072] This wastewater treatment device consists of a rotatable inner shell 3, a drain pipe 4, a sealing block 6, a pressing block 8, and a filter block 10. During the drainage process, the flocculent matter in the wastewater remains in the drain pipe 4. Then, the pressing block 8 and the filter block 10 squeeze each other to dehydrate the flocculent matter, reducing the amount of wastewater residue in the flocculent matter. No secondary treatment is required, thus reducing the difficulty of treating dyeing wastewater.

[0073] As a further embodiment of the present invention, the first pushing mechanism includes:

[0074] Drive rod 15, the bottom end of drive rod 15 passes through the top end of inner shell 3 and is slidably connected to inner shell 3, the bottom end of drive rod 15 extends into inner shell 3, and the bottom end of drive rod 15 is rotatably connected to mounting block 18.

[0075] Several connecting rods 19, the top ends of which are rotatably connected to the side wall of the mounting block 18, and the other ends are rotatably connected to the sealing block 6 at the corresponding position;

[0076] Rotary seat 20 is rotatably connected to the top of drive rod 15;

[0077] Cylinder 21 is fixedly connected to the top of housing 1 via the first bracket, and the bottom end of the telescopic rod of cylinder 21 is fixedly connected to the top of rotating seat 20.

[0078] Specifically, by setting up a drive rod 15 and a cylinder 21, when it is necessary to discharge the wastewater in the inner shell 3, the cylinder 21 is activated, causing the cylinder 21 to pull the rotating seat 20 upward, thereby causing the drive rod 15 to move upward. Under the pull of the connecting rod 19, the sealing block 6 pulls the pressure block 8 to move, and the pressure block 8 disengages from the drain pipe 4, thereby canceling the seal on the drain pipe 4 and allowing the wastewater to be discharged through the drain pipe 4.

[0079] After the wastewater is discharged, the telescopic rod of cylinder 21 pushes the rotating seat 20 downward to move and reset, causing the drive rod 15 to move downward. Under the push of the connecting rod 19, the sealing block 6 is reinserted into the drain pipe 4, sealing the drain pipe 4. At the same time, the pressure block 8 squeezes the flocculent material in the drain pipe 4, causing the flocculent material to dehydrate.

[0080] As a further embodiment of the present invention, the rotary drive mechanism includes:

[0081] The drive motor 22 is fixedly connected to the top of the housing 1 via the second bracket, and the output shaft of the drive motor 22 is slidably inserted into the drive rod 15.

[0082] Upper bushing 23 is fixedly connected to the top of the inner shell 3. The upper bushing 23 has a first slot 2301 symmetrically opened inside, and a first annular groove 2302 is opened below the first slot 2301 inside.

[0083] Two first locking blocks 16 are symmetrically fixedly connected to the outer wall of the drive rod 15, and the first locking blocks 16 are slidably connected inside the upper bushing 23;

[0084] It also includes a stirring mechanism, which includes:

[0085] The lower bushing 24 is rotatably connected to the bottom end of the upper bushing 23. A second annular groove 2401 is provided inside the lower bushing 24, and a second slot 2402 is symmetrically provided below the second annular groove 2401 inside the lower bushing 24.

[0086] Two second locking blocks 17 are symmetrically fixedly connected to the outer wall of the drive rod 15, and the second locking blocks 17 are slidably connected inside the lower bushing 24.

[0087] Several stirring rods 25 are fixedly connected in an array to the outer wall of the bottom end of the lower bushing 24;

[0088] Specifically, by setting up a drive motor 22 and an upper bushing 23, during the upward movement of the drive rod 15, the first locking block 16 enters the first locking groove 2301 from the first annular groove 2302, and the second locking block 17 enters the second annular groove 2401 from the second locking groove 2402. Then, the drive motor 22 causes the drive rod 15 to rotate, and under the action of locking, the inner shell 3 rotates synchronously.

[0089] As the drive rod 15 moves downward, the first locking block 16 enters the first annular groove 2302 from the first locking slot 2301, and the second locking block 17 enters the second locking slot 2402 from the second annular groove 2401. Then, the drive rod 15 is rotated by the drive motor 22. Under the action of locking, the lower bushing 24 drives the stirring rod 25 to rotate, thereby stirring the wastewater in the inner shell 3.

[0090] As a further embodiment of the present invention, the second driving mechanism includes:

[0091] U-shaped drive plate 26, which is slidably connected to the outer wall of the top end of the drain pipe 4, and a first pushing slope is provided at the end of the U-shaped drive plate 26;

[0092] Push block 27 is fixedly connected to the top of filter block 10, and the end of push block 27 is provided with a second push slope that is adapted to the first push slope.

[0093] Drive slot 2601 is formed at the top of U-shaped drive plate 26. Drive slot 2601 has straight slot and oblique slot.

[0094] The push frame 28 has a push pin fixedly connected to one end, which is slidably connected in the drive groove 2601. The other end of the push frame 28 passes through the inner shell 3 and is slidably connected to the inner shell 3. The end of the push frame 28 is fixedly connected to the sealing block 6.

[0095] Specifically, by setting up a U-shaped drive plate 26 and a pusher block 27, during the process of the sealing block 6 driving the pressure block 8 to insert into the drain pipe 4, the pusher frame 28 first moves along the straight groove, and then enters the inclined groove. Under the drive of the inclined groove, the U-shaped drive plate 26 moves away from the pusher block 27. Under the action of the second spring 11, the filter block 10 moves away from the end of the drain pipe 4 quickly, thereby completing the slag discharge work.

[0096] As the sealing block 6 moves the pressure block 8 away from the drain pipe 4, the pusher 28 first moves along the inclined groove and then enters the straight groove. Driven by the inclined groove, the U-shaped drive plate 26 approaches the pusher 27, thereby pushing the filter block 10 to move towards the end of the drain pipe 4 and contacting the end of the drain pipe 4 to complete the sealing and filtration of the end of the drain pipe 4. During the process of pushing the filter block 10 towards the end of the drain pipe 4, the second spring 11 is stretched and stores elastic potential energy to facilitate the next slag discharge operation.

[0097] As a further embodiment of the present invention, it also includes:

[0098] The slag discharge chamber 103 is located at the bottom of the inner shell 1 and is used to receive slag material.

[0099] The second annular sealing plate 104 is rotatably connected to the slag discharge chamber 103.

[0100] Several isolation covers 5 are fixedly connected to the outer wall of the inner shell 3 at the positions corresponding to the drain pipe 4, so as to cover the filter block 10 and the drain pipe 4. The bottom end of the isolation cover 5 passes through the second annular sealing plate 104 and is fixedly connected to the second annular sealing plate 104. The filter block 10 is slidably connected to the isolation cover 5.

[0101] Specifically, by setting up a slag discharge chamber 103 and an isolation cover 5, the isolation cover 5 covers the filter block 10 and the end of the drain pipe 4, so that even if there is a gap between the filter block 10 and the drain pipe 4 and wastewater leaks, it can still enter the slag discharge chamber 103 through the isolation cover 5, avoiding contamination of the equipment. It can also guide the slag discharge, thereby achieving precise material discharge into the slag discharge chamber 103.

[0102] As a further embodiment of the present invention, it also includes:

[0103] The annular plate 29 is rotatably connected to the bottom of the inner shell 3. The bottom surface of the annular plate 29 is fixedly connected to the bottom surface of the outer shell 1. The top of the annular plate 29 is fixedly connected with an array of scrapers 30, which are in contact with the inner wall of the inner shell 3.

[0104] Specifically, by setting up annular plate 29 and scraper 30, the annular plate 29 cannot rotate during the rotation of inner shell 3, thereby causing relative movement between scraper 30 and inner wall of inner shell 3. This facilitates the scraping of flocculent material attached to inner wall of inner shell 3. When drain pipe 4 moves to scraper 30, under centrifugal force, the flocculent material at scraper 30 enters drain pipe 4, collecting as much flocculent sediment as possible in inner shell 3 and reducing the residue of flocculent sediment in inner shell 3.

[0105] As a further embodiment of the present invention, it also includes:

[0106] An arc-shaped groove 1001 is formed at the end of the filter block 10. A connecting plate 12 is symmetrically slidably connected to both sides of the end of the filter block 10. A third spring 13 is fixedly connected between the connecting plate 12 and the filter block 10.

[0107] The filter screen 14 is fixedly connected to two connecting plates 12 on both sides.

[0108] The ends of the pressure block 8 are arc-shaped;

[0109] Specifically, by setting up a filter screen 14 and an arc-shaped pressure block 8, as the pressure block 8 approaches and squeezes the filter screen 14, the filter screen 14 deforms, the two connecting plates 12 move closer to each other, and the third spring 13 is stretched and generates elastic force, thereby increasing the contact area between the arc-shaped pressure block 8 and the filter screen 14, which is conducive to fully squeezing and dewatering the flocculent sediment; when the pressure block 8 moves away from the filter screen 14, under the elastic force of the third spring 13, the two connecting plates 12 drive the filter screen 14 to reset. At the moment the filter screen 14 resets, the waste residue attached to the filter screen 14 is shaken, thereby completing the rapid removal, which helps to reduce the residue residue on the filter screen 14 and reduce clogging.

[0110] Working principle of this invention:

[0111] First, the mixture of wastewater, decolorizing agent and flocculant is injected into the inner shell 3 through the water inlet pipe 2. Then, it is stirred by the stirring mechanism. After stirring is completed, the sealing block 6 is moved together with the pressure block 8 by the first pushing mechanism. The pressure block 8 is disengaged from the drain pipe 4, and the seal on the drain pipe 4 is removed, so that the wastewater in the inner shell 3 is discharged through the drain pipe 4. After the sewage passes through the drain pipe 4, it will reach the filter block 10. The filter block 10 is used to filter the flocculent precipitate in the wastewater and make the flocculent precipitate deposit in the drain pipe 4.

[0112] After the pressure block 8 is removed from the drain pipe 4 to cancel the seal on the drain pipe 4, the rotary drive mechanism is activated. The rotary drive mechanism causes the inner shell 3 to rotate. Under the action of centrifugal force, the particles in the wastewater will move in the direction with a larger rotation radius and settle to the bottom, and finally enter the drain pipe 4. This helps to increase the settling speed of the particles in the wastewater. In addition, under the action of centrifugal force, the wastewater will pressurize the filter block 10, which helps to increase the wastewater discharge speed.

[0113] After the wastewater is discharged, the sealing block 6 moves the pressure block 8 through the pushing mechanism to reseal the drain pipe 4. During the movement of the sealing block 6 and the pressure block 8, a large amount of flocculent material is present in the drain pipe 4, which occupies the space of the drain pipe 4 and puts pressure on the pressure block 8 in the opposite direction, causing the first spring 7 to be compressed and deformed. Since the forces are mutual, the flocculent material in the drain pipe 4 will be compressed during the continuous movement of the sealing block 6 pushing the pressure block 8, and then the wastewater in the flocculent material will be squeezed out. The squeezed-out wastewater enters the drain chamber 101 through the filter block 10 and the connecting pipe 9. The wastewater in the drain chamber 101 is discharged through the external pipe.

[0114] After extrusion, the filter block 10 is moved into the connecting pipe 9 by the second pushing mechanism, thereby creating a discharge space between the filter block 10 and the pressing block 8. Under the action of gravity, the waste residue between the filter block 10 and the pressing block 8 falls out and is discharged.

[0115] After completing the above operations, the filter block 10 is moved closer to the end of the drain pipe 4 and makes contact with the end of the drain pipe 4 by the second pushing mechanism. Then, the sealing block 6 re-seals the drain pipe 4. Next, the wastewater to be treated is injected through the water inlet pipe 2, and then the wastewater treatment is carried out again according to the above operations.

[0116] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
