Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and more particularly to a wastewater treatment device for producing aminosulfonic acid. Background Art

[0002] Aminosulfonic acid is an important fine chemical product with a wide range of uses. It can be used as a cleaning agent for food industry equipment, as a bleaching aid in the paper industry, and as an eliminator and fixative in the manufacture of dyes, pigments and leather dyeing.

[0003] The production process of aminosulfonic acid produces a large amount of wastewater containing high concentrations of inorganic salts and organic matter. These wastewaters need to be specially treated to meet discharge standards or be recycled and reused. Currently, the more commonly used method is membrane separation, including microfiltration, reverse osmosis, ultrafiltration and nanofiltration. Membrane separation can effectively separate solid particles and soluble substances in wastewater;

[0004] In order to avoid clogging of the separation membrane, the wastewater needs to be pretreated before membrane separation to remove solid particle impurities such as suspended matter, sharp particles and slightly soluble salts in the wastewater. Flocculants are usually added to the wastewater to make the solid particle impurities clump together to form floccules such as sediment or scum. In order to make the flocculant fully contact with the solid particles, the flocculant in the wastewater needs to be fully stirred. However, in a continuous high-speed stirring environment, the clumped floc structure is easily broken up and destroyed, thereby affecting the sedimentation or floating efficiency of the floccules. In addition, batch addition of flocculants will also cause local accumulation of flocculants, resulting in uneven distribution of flocculants, thereby affecting the formation effect of floccules. Summary of the invention

[0005] The object of the present invention is to provide a wastewater treatment device for aminosulfonic acid production to solve the problem that the stirring environment and batch addition of flocculants affect the stability of the process of solid particles forming floccules in the existing wastewater treatment process.

[0050] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0051] See also Figure 1 and Figure 2 The present invention discloses a wastewater treatment device for aminosulfonic acid production, comprising a treatment tank 100, a guide column 200, a movable plate 300, a feeding mechanism 400, a fixed plate 500, a salvaging mechanism 600 and a driving mechanism 700, wherein a support 101 is provided at the bottom of the treatment tank 100;

[0052] See also Figure 3 The guide column 200 is arranged at the center of the processing tank 100. The guide column 200 includes a column 210 vertically fixed in the processing tank 100. The column 210 is provided with a spiral groove 220 and a straight groove 230. A one-way limit assembly 240 is arranged at each intersection of the spiral groove 220 and the straight groove 230.

[0053] See also Figure 5 The movable disk 300 includes a movable disk body 310 movably mounted on the column 210, and a latch 311 adapted to one of the spiral groove 220 and the straight groove 230 is arranged on the inner side of the movable disk body 310; a plurality of feeding mechanisms 400 are arranged and evenly distributed on the movable disk body 310 in the circumferential direction, and are used to feed flocculants into the processing tank 100;

[0054] See also Fig.10 The fixed plate 500 includes a fixed plate body 510 fixedly mounted on the top of the column 210, and the fixed plate body 510 is provided with a filling assembly for supplying flocculant to the feeding mechanism 400; the salvaging mechanism 600 is provided with multiple groups and evenly distributed on the fixed plate body 510 in the circumferential direction, and is used to salvage the scum in the treatment tank 100;

[0055] The driving mechanism 700 is disposed at the bottom of the processing tank 100 and is used to drive the movable plate 300 to move;

[0056] Specifically, the wastewater to be treated is injected into the treatment tank 100. In the initial state, the movable disk 300 is located at the lower end of the guide column 200, and the latch 311 is located at the junction of the lower end of the spiral groove 220 and the lower end of the straight groove 230. The driving mechanism 700 applies a vertical upward thrust to the movable disk 300 to push the movable disk 300 to move upward along the guide column 200. During the rising process of the movable disk 300, the latch 311 slides vertically upward along the straight groove 230, and the movable disk 300 as a whole does not rotate circumferentially relative to the guide column 200, thereby minimizing the disturbance effect of the feeding mechanism 400 on the wastewater and avoiding the destruction of the formed floccules.

[0057] When the movable disk 300 reaches the upper end of the guide column 200, the movable disk 300 contacts the fixed disk 500, and the flocculant is supplied to the feeding mechanism 400 on the movable disk 300 through the filling assembly on the fixed disk 500; then the movable disk 300 moves downward along the guide column 200 under the action of gravity, and due to the limitation of the one-way limit assembly 240, the latch 311 cannot slide downward along the straight groove 230, so that the latch 311 is switched to the spiral groove 220, so that the latch 311 moves downward along the spiral groove 220. The spiral groove 220 guides and limits the moving path of the latch pin 311, so that the movable disk 300 descends vertically and rotates circumferentially relative to the guide column 200, thereby driving the feeding mechanism 400 to rotate synchronously. The feeding mechanism 400 that is continuously descending and rotating circumferentially is used to feed the flocculant into the wastewater in the treatment tank 100, which not only enables the flocculant to fully contact with the wastewater in each area, but also improves the mixing effect of the solid particles in the wastewater and the flocculant through the stirring action, thereby accelerating the formation of floccules such as scum and sediment;

[0058] The scum floats to the surface of the wastewater, while the sediment sinks to the bottom of the wastewater. The scum on the water surface is fished out by the fishing mechanism 600 on the fixed plate 500.

[0059] It should be noted that the present invention provides a movable disk 300 that can vertically rise and spirally descend along the guide column 200. When the movable disk 300 spirally descends, it drives the feeding mechanism 400 to spirally rotate, thereby promoting the flocculant to combine with the solid particles in the wastewater and quickly form sediment and scum, thereby improving the separation effect of the solid particles. When the movable disk 300 rises vertically, the feeding mechanism 400 no longer rotates, thereby minimizing the disturbance effect on the wastewater, which is conducive to the rapid sedimentation or floating of the formed flocs, thereby improving the separation efficiency of the solid particles.

[0060] In one embodiment, see Figure 3 and Figure 4 In order to realize the path switching of the bayonet 311 between the spiral groove 220 and the straight groove 230, the one-way limiting assembly 240 includes a one-way limiting plate 241 rotatably mounted on the column 210, the one-way limiting plate 241 is arranged at each intersection of the spiral groove 220 and the straight groove 230, the one-way limiting plate 241 is inclined and consistent with the slope of the spiral groove 220, the downwardly inclined end of the one-way limiting plate 241 is hinged to one side of the straight groove 230, and the upwardly inclined end of the one-way limiting plate 241 is inserted into the slot 242 on the other side of the straight groove 230;

[0061] In the initial state, one end of the one-way limiting plate 241 is always inserted into the corresponding slot 242. At this time, the inclination of the one-way limiting plate 241 is adapted to the spiral slot 220. At this time, the one-way limiting plate 241 blocks the straight slot 230, and the one-way limiting plate 241 can only be turned upward in the initial state but cannot be turned downward in the initial state.

[0062] When the driving mechanism 700 drives the movable disk 300 to rise vertically, the latch pin 311 rises synchronously along the straight groove 230. When the latch pin 311 contacts the one-way limiting plates 241 at each level, the corresponding one-way limiting plates 241 flip to one side under the vertical impact of the latch pin 311, so that the channel of the straight groove 230 is opened, so that the latch pin 311 can smoothly pass through the intersections of the straight groove 230 and the spiral groove 220 until the movable disk 300 reaches the upper end of the guide column 200. After the latch pin 311 passes the position of the corresponding one-way limiting plate 241, the one-way limiting plate 241 at that location can automatically flip downward and reset under the action of gravity.

[0063] When the movable disk 300 moves downward along the guide column 200 under the action of gravity, the one-way limit plate 241 cannot flip downward after being reset, so that the one-way limit plate 241 blocks the straight groove 230. Under the guidance of the one-way limit plate 241, the pin 311 is forced to enter the spiral groove 220 and spirally descend along the spiral groove 220. Since the one-way limit plates 241 at each intersection of the straight groove 230 and the spiral groove 220 can guide the pin 311, the pin 311 can continue to spirally descend along the spiral groove 220 until the movable disk 300 reaches the lower end of the guide column 200.

[0064] Further, considering that when the movable plate 300 reaches the upper end of the guide column 200, the latch 311 passes through the uppermost set of one-way limit plates 241, in order to facilitate the reset of the one-way limit plates 241 and the smooth switching of the path of the latch 311, please refer to Figure 4 The upper end of the straight groove 230 is provided with a buffer section 231. When the pin 311 passes through the top set of one-way limit plates 241 and enters the buffer section 231, the one-way limit plate 241 flips downward and resets under the action of gravity, and then the pin 311 falls vertically for a distance with the movable disk body 310 under the action of gravity until the pin 311 contacts the upper end surface of the top one-way limit plate 241. Since the one-way limit plate 241 cannot flip downward at this time, the pin 311 is switched to the adjacent spiral groove 220 under the guidance of the one-way limit plate 241, so as to realize the smooth switching of the path of the pin 311.

[0065] In yet another embodiment, see Figure 5 and Figure 6The feeding mechanism 400 includes a first rotating shaft 410 rotatably mounted on the movable disk body 310, a paddle 420 is mounted on one end of the first rotating shaft 410 away from the movable disk body 310, a first connector 320 is disposed on the upper end surface of the movable disk body 310, and a connecting pipe 321 is connected between the first connector 320 and each paddle 420; the movable disk body 310 is also provided with a paddle driving assembly for driving the paddles 420 on each group of the first rotating shaft 410 to flip;

[0066] Specifically, during the vertical ascent of the movable disc 310, each group of the paddles 420 is adjusted to a vertical state through the paddle driving assembly, that is, the paddles 420 as a whole are perpendicular to the horizontal plane, thereby reducing the contact area between the paddles 420 and the wastewater in the vertical direction, and the paddles 420 will not rotate circumferentially, thereby reducing the disturbance of the paddles 420 to the flocs in the wastewater, avoiding the secondary destruction of the formed flocs, and facilitating the rapid sedimentation and floating of the flocs;

[0067] When the movable disk 310 reaches the upper end of the guide column 200, the first connector 320 is connected to the filling assembly on the fixed disk 510, so that flocculant is filled into the first connector 320 through the filling assembly, and then the flocculant enters the corresponding dial plate 420 through each connecting pipe 321;

[0068] During the spiral descent of the movable disc 310, each group of the paddles 420 is adjusted to an inclined state through the paddle driving assembly, that is, the paddles 420 as a whole form a certain angle with the horizontal plane, and the angle range can be 30-60 degrees, so as to increase the contact area between the paddles 420 and the wastewater in the vertical direction; when the movable disc 310 spirally descends along the spiral groove 220, the inclined paddles 420 are driven to spirally descend synchronously, and during the spiral descent of the paddles 420, the flocculant in the paddles 420 can be continuously thrown out and enter the wastewater under the action of centrifugal force, so that the flocculant can cover all areas of the wastewater, and at the same time, the circumferential rotation of the inclined paddles 420 can accelerate the stirring and disturbance effect on the solid particles and flocculants in the wastewater, so that the flocculants can fully contact with the solid particles in the wastewater and quickly form flocs, thereby accelerating the formation of flocs;

[0069] See also Figure 7 , for the process of throwing out the flocculant in the paddle 420, the paddle 420 includes a shell 421 fixedly connected to the first rotating shaft 410 and a storage bin 422 arranged in the shell 421, and the storage bin 422 is connected to the corresponding connecting pipe 321; a plurality of feeding racks 423 are equidistantly arranged on the storage bin 422, and a sealing plate 424 is rotatably arranged at the opening of the feeding rack 423;

[0070] When the movable disk 310 contacts the fixed disk 510 , the filling assembly fills the flocculant into the storage bin 422 of each dial plate 420 through the first connector 320 ;

[0071] In the initial state, the sealing plate 424 remains in a normally closed state to block the opening of the corresponding feeding rack 423. When the dial plate 420 rotates spirally, the sealing plate 424 opens under the action of centrifugal force, so that the flocculant in the storage bin 422 is thrown out from each feeding rack 423.

[0072] It should be noted that, in view of the normally closed state of the sealing plate 424, a coil spring can be provided at the rotation connection between the sealing plate 424 and the feeding rack 423, so that the sealing plate 424 remains normally closed under the elastic force of the coil spring. When the dial plate 420 rotates spirally, the centrifugal force generated by it can overcome the elastic force of the coil spring, so that the sealing plate 424 is automatically opened. When the dial plate 420 does not rotate, the sealing plate 424 can be automatically reset and closed under the action of the coil spring.

[0073] Alternatively, the sealing plate 424 and the feeding rack 423 can be arranged to be magnetically connected, so that the sealing plate 424 remains normally closed under the action of magnetism, and when the dial plate 420 rotates spirally, the centrifugal force it generates can overcome the magnetic attraction force, so that the sealing plate 424 automatically opens, and when the dial plate 420 does not rotate, the sealing plate 424 can automatically reset and close under the action of the magnetic attraction force.

[0074] In addition, in order to allow the flocculants to have sufficient time to settle and float, after the movable disk 300 spirally descends to the lower end of the guide column 200 to complete a complete cycle, the movable disk 300 can be paused for a certain period of time until the flocculants generated in the cycle are completely settled or floated, and then the movable disk 300 is driven again by the driving mechanism 700 to move for the next cycle.

[0075] For further information, see Figure 8 and Fig. 9 The paddle driving assembly includes a first annular chamber 312 opened in the movable disk body 310, a first ring sleeve 313 is fixedly installed in the first annular chamber 312, a first bevel gear ring 314 is rotatably installed in the first ring sleeve 313, and a first bevel gear 315 meshing with the first bevel gear ring 314 is installed at one end of each first rotating shaft 410 extending into the first annular chamber 312, a first gear 316 is installed on one of the first rotating shafts 410, and a first rack 317 meshing with the first gear 316 is vertically slidably penetrated on the movable disk body 310;

[0076] Specifically, when the movable plate 310 moves to the lower end of the guide column 200, the first rack 317 contacts the driving mechanism 700, thereby pushing the first rack 317 upward, and driving one of the first rotating shafts 410 to rotate through the meshing transmission of the first rack 317 and the first gear 316. At the same time, under the meshing transmission of the first bevel gear 315 and the first bevel gear ring 314, the other first rotating shafts 410 are driven to rotate synchronously, so as to achieve synchronous adjustment of each dial plate 420, so as to synchronously adjust each group of dial plates 420 to a vertical state;

[0077] When the movable plate 310 moves to the upper end of the guide column 200, the first rack 317 contacts the fixed plate 510, thereby pushing the first rack 317 downward, and driving one of the first rotating shafts 410 to rotate through the meshing transmission of the first rack 317 and the first gear 316. At the same time, under the meshing transmission of the first bevel gear 315 and the first bevel gear ring 314, the other first rotating shafts 410 are driven to rotate synchronously, so as to achieve synchronous adjustment of each dial plate 420, so as to synchronously adjust each group of dial plates 420 to a tilted state;

[0078] It should be noted that, in actual application, the length of the first rack 317, the transmission ratio of the first rack 317 to the first gear 316, and the transmission ratio of the first bevel gear 315 to the first bevel gear ring 314 can be set so that when the first rack 317 moves to the upper stroke limit relative to the movable disk body 310, the paddle 420 is just adjusted to a vertical state; similarly, when the first rack 317 moves to the lower stroke limit relative to the movable disk body 310, the paddle 420 is just adjusted to a tilted state;

[0079] In addition, the first rack 317 can maintain its current state when there is no external force. That is, only when it reaches the upper end or the lower end of the guide column 200 and contacts the corresponding trigger component, it will slide relative to the movable disk body 310, thereby switching the posture of the dial plate 420. During the vertical ascent or spiral descent of the movable disk body 310, the first rack 317 will not slide relative to the movable disk body 310, thereby ensuring the stability of the posture of the dial plate 420 during the vertical ascent or spiral descent.

[0080] In further embodiments, see Fig.10 , Fig.11 and Fig.14The salvage mechanism 600 includes a second rotating shaft 610 rotatably mounted on the fixed disk body 510 and a mounting ring 630 detachably connected to the fixed disk body 510. A salvage frame 620 is mounted on the end of the second rotating shaft 610 away from the fixed disk body 510. A filter hole 621 is provided on the salvage frame 620. A plurality of slag collecting boxes 631 are evenly distributed circumferentially on the mounting ring 630. The slag collecting boxes 631 correspond to each salvage frame 620 one by one. A flip driving assembly for driving the salvage frames 620 on each group of the second rotating shaft 610 to flip is also provided on the fixed disk body 510.

[0081] Specifically, the second rotating shafts 610 are driven to rotate synchronously through the flipping drive assembly, thereby driving each group of salvage frames 620 to flip upward synchronously, so as to pick up the scum on the water surface and pour it into the corresponding scum collecting box 631. During the salvage process, the wastewater flows back to the treatment tank 100 through the filter hole 621 again; the salvage frame 620 is intermittently flipped, so as to achieve periodic salvage of scum on the wastewater surface, thereby preventing scum from accumulating on the wastewater surface.

[0082] It should be noted that, in order to ensure the effect of scum salvaging, multiple groups of salvage frames 620 are arranged along the circumferential direction, and the total salvage range of each salvage frame 620 can cover the entire water surface, thereby avoiding the omission of scum.

[0083] For further information, see Fig.12 and Fig.13 In order to enable the salvage mechanism 600 to automatically perform periodic salvage operations, the flip drive assembly includes a second annular chamber 511 opened in the fixed disk body 510, a second ring sleeve 512 is fixedly installed in the second annular chamber 511, a second bevel gear ring 513 is rotatably installed in the second ring sleeve 512, and one end of each second rotating shaft 610 extending into the second annular chamber 511 is installed with a second bevel gear 514 meshing with the second bevel gear ring 513, one of the second rotating shafts 610 is installed with a second gear 515, and a second rack 516 meshing with the second gear 515 is vertically slidably penetrated on the fixed disk body 510; limit blocks 517 are provided at the upper and lower ends of the second rack 516, and a spring 518 is provided between the limit block 517 at the lower end and the lower end surface of the fixed disk body 510;

[0084] Specifically, when the movable disk 310 reaches the upper end of the guide column 200, the first rack 317 on the movable disk 310 contacts the second rack 516 on the fixed disk 510. As the distance between the movable disk 310 and the fixed disk 510 gradually decreases, the first rack 317 gradually slides downward relative to the movable disk 310, thereby driving the dial plate 420 to switch to a tilted posture; and the second rack 516 gradually slides upward relative to the fixed disk 510, and the spring 518 is compressed, thereby driving the second gear 515 to rotate, so that one of the second rotating shafts 610 rotates, and under the meshing transmission of the second bevel gear 514 and the second bevel gear ring 513, the other second rotating shafts 610 are driven to rotate synchronously, so as to realize the synchronous flipping of each salvage frame 620, so as to synchronously salvage the scum on the water surface;

[0085] When the movable plate 310 is separated from the fixed plate 510 , the second rack 516 automatically slides downward relative to the fixed plate 510 and resets under the elastic force of the spring 518 , thereby driving each group of salvage frames 620 to flip and reset synchronously.

[0086] Furthermore, in the process of connecting the movable disc 310 and the fixed disc 510 to add flocculant, the lower end surface of the fixed disc 510 is provided with a second connector 520 adapted to the first connector 320, and the fixed disc 510 is also provided with a feed pipe 521 connected to the second connector 520, and the feed pipe 521 is connected to an external filling device;

[0087] When the movable disk 310 contacts the fixed disk 510, the first connector 320 and the second connector 520 are spliced ​​and connected to each other, and the flocculant is injected into the feed pipe 521 through the external filling equipment. The flocculant enters the corresponding storage bin 422 through the second connector 520, the first connector 320 and each connecting pipe 321, thereby realizing the periodic automatic filling of the flocculant. By periodically replenishing the flocculant, the flocculant can be added in batches to avoid local accumulation caused by the single batch addition of flocculant, thereby improving the contact effect between the flocculant and the solid particles.

[0088] For further information, see Figure 1 The driving mechanism 700 includes a driving cylinder 701 fixedly mounted on the bottom of the processing tank 100, a connecting plate 702 is provided at the output end of the driving cylinder 701, a plurality of lifting columns 703 that are movable and extend into the processing tank 100 are provided on the connecting plate 702, and a driving ring 704 is installed on the upper end of the lifting column 703;

[0089] When the movable disk 300 reaches the lower end of the guide column 200, the driving cylinder 701 drives the driving ring 704 to move upward, so that the driving ring 704 applies a vertical upward thrust to the movable disk 300, so that the movable disk 300 can rise vertically along the guide column 200 by itself under the action of the thrust; when the driving ring 704 drives the movable disk 300, it can also push the first rack 317 to slide upward relative to the movable disk body 310, so as to realize the switching of the vertical posture of the shift plate 420.

[0090] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
