Description

Technical Field

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

[0002] At present, the traditional process flow for treating textile wastewater is generally as follows: first, large particle impurities such as fiber debris are removed through screening and grating, and then the pH value of the wastewater is adjusted by neutralization; in the core treatment stage, organic pollutants and suspended solids are degraded through coagulation and sedimentation combined with biological treatment (such as activated sludge or biofilm method), and advanced oxidation technology (such as ozone oxidation) is used to decolorize and decompose difficult-to-degrade dye substances; finally, residual pollutants are deeply treated through activated carbon adsorption or membrane separation technology, and after disinfection, they are discharged or reused in compliance with standards.

[0003] During the coagulation and sedimentation treatment, a coagulation and sedimentation device is required to separate and filter the impurities in the wastewater. The coagulation and sedimentation device mainly achieves the precipitation effect of impurities by adding coagulants and coagulants to the wastewater. Therefore, the addition effect of coagulants and coagulants directly affects the wastewater treatment efficiency. For the existing coagulation and sedimentation devices, most of them adopt a mobile automatic dosing system, but there are two major technical pain points in actual operation: first, the dynamic water flow environment causes the accuracy of additive dosing to be impaired. Although accurate control can be achieved through the integrated flow rate and flow online monitoring system, the sensor maintenance and system upgrade costs are high, which restricts the feasibility of technical transformation of existing treatment facilities; second, the mixing uniformity of the additive and the wastewater is restricted by the fluid dynamics characteristics. Even if a mechanical stirring device is configured, its mixing efficiency still fluctuates due to the turbulent state of the water flow, resulting in a concentration gradient of the agent in the local area, which affects the sufficiency of the flocculation reaction. Therefore, there is an urgent need for a new treatment device that has both low-cost transformation adaptability, dynamic compensation dosing accuracy and enhanced hydraulic mixing effect.

[0012] As a further optimization solution of the present invention, the fixed gear is an incomplete gear with a non-meshing section, and the non-meshing section of the incomplete gear corresponds to the position of the liquid inlet pipeline.

[0013] As a further optimization scheme of the present invention, a contraction drive assembly for driving the partition plate to contract toward the inner side of the rotating drum is provided on the liquid inlet cylinder body, and the contraction drive assembly includes a track plate and the same number of sliding wheels and return springs as the partition plate, the track plate is fixedly mounted on the inner side of the liquid inlet cylinder body, a traction groove is provided on one side of the track plate, and several sliding wheels are rollingly connected with the traction groove, the traction groove is composed of a first arc groove coaxial with the rotating drum and a second arc groove with the center of the circle facing the inner side of the liquid inlet cylinder body, the second arc groove is arranged near the discharge port, and an active groove corresponding to the partition plate is provided on the inner side of the rotating drum, one end of several sliding wheels slides through the corresponding active groove and is fixed to the corresponding side of the partition plate, one end of several return springs is fixed to one side of several sliding wheels in a one-to-one manner, and the other end of several return springs is fixed to the inner side of the corresponding active groove.

[0021] Mechanical beat control is adopted, and the low-speed rotation of the drum drives the periodic displacement of the pretreatment chamber. The gradually expanding diversion and drainage port is used to achieve the smooth spreading of the mixed liquid, forming a "discrete treatment-continuous discharge" working beat, which not only ensures the mixing time of a single chamber but also maintains the system processing flux;

[0022] The built-in three-dimensional mixing structure is adopted, and the curved stirring component is integrated in the drum shaft system. The vertical swirl flow and radial shear flow are synchronously stimulated during the rotation of the cavity, and the mass transfer efficiency in a limited space is enhanced through the multi-directional eddy current coupling effect.

[0023] The treatment agent addition mechanism system fundamentally solves the contradiction between dynamic dosing accuracy and mixing uniformity: the static dosing environment of the pretreatment chamber replaces the flow sensor closed-loop control, while the cavity geometry constraints and the composite flow field generation mechanism synergistically improve the dynamic efficiency of the mixing process, and ultimately achieves process indicators that can only be achieved by traditional electronic control systems through a purely mechanical structure.

DETAILED DESCRIPTION

[0034] 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.

[0035] Please refer to Figures 1 to 3A textile wastewater treatment device comprises: a treatment tank body 1, a stirring mechanism 2 and a treatment agent adding mechanism 3. The treatment agent adding mechanism 3 is installed at one end of the treatment tank body 1 where water enters, and the treatment agent adding mechanism 3 comprises a liquid inlet cylinder 31, a liquid inlet pipe 32, a treatment agent delivery pipe 33, a rotating drum 34, a rotating drive assembly 35, an agitating assembly 36 and four partition plates 38. Among them, the liquid inlet cylinder 31 is detachably installed on one side of the treatment tank body 1, the liquid inlet pipe 32 and the treatment agent delivery pipe 33 are both connected to the outside of the liquid inlet cylinder 31, the liquid inlet pipe 32 is connected to an external wastewater delivery mechanism, and the treatment agent delivery pipe 33 is connected to an external treatment agent delivery mechanism, and the liquid inlet pipe 32 is located at the upper left of the liquid inlet cylinder 31, and the treatment agent delivery pipe 33 is located in the middle of the top of the liquid inlet cylinder 31. The bottom of the liquid inlet cylinder 31 is provided with a discharge port 39 facing one side of the treatment tank body 1, and the rotating drum 34 is coaxially rotatably installed on the inner side of the liquid inlet cylinder 31. Four partition plates 38 are evenly slidably installed along the circumference of the outer annular surface of the rotating drum 34. One end of the four partition plates 38 away from the rotating drum 34 is slidably fitted with the inner wall of the liquid inlet cylinder 31. A pretreatment chamber for temporarily storing quantitative wastewater is formed between every two partition plates 38. The surface of the partition plates 38 is provided with an anti-corrosion coating. The rotary drive assembly 35 is matched with one end of the rotating drum 34 for driving the rotating drum 34 to rotate in the liquid inlet cylinder 31. The stirring assembly 36 is arranged on the rotating drum 34, and the wastewater stored in each pretreatment chamber is stirred by the stirring assembly 36.

[0036] It should be noted that when the above-mentioned treatment device is used to treat textile wastewater, the wastewater is introduced into the liquid inlet cylinder 31 through the liquid inlet pipe 32 and enters the corresponding pretreatment chamber. The rotary drive component 35 drives the drum 34 to rotate slowly, and the partition plate 38 rotates with the drum 34, so that the first pretreatment chamber filled with wastewater gradually moves away from the liquid inlet pipe 32. At the same time, the treatment agent is quantitatively introduced into the pretreatment chamber through the treatment agent delivery pipe 33. After that, the next pretreatment chamber moves to the position corresponding to the liquid inlet pipe 32, and the wastewater begins to enter the pretreatment chamber, while no more wastewater enters the first pretreatment chamber. The wastewater in the first pretreatment chamber is stirred by the stirring component 36, so that the treatment agent and the wastewater can be quickly mixed. Since the wastewater temporarily stored in the pretreatment chamber The amount is small, and the volume of the wastewater remains basically unchanged during the activity. In addition, the drum 34 rotates at a low speed, so that the wastewater is in a slowly flowing state. At this time, the treatment agent and the wastewater can be quickly and evenly mixed, and the amount of treatment agent added can also be kept accurate. Since it takes a certain amount of time for the first pretreatment chamber to move to the drain port 39, the stirring component 36 is sufficient to fully mix the wastewater and the treatment agent during this period of time. When the first pretreatment chamber moves to the drain port 39, the mixed wastewater will be directly discharged downward from the drain port 39 into the treatment tank body 1, and then the second pretreatment chamber moves to the drain port 39 to continue to discharge the mixed wastewater. In this way, the wastewater can be continuously introduced into the treatment tank body 1 without causing too much impact on the wastewater transportation speed.

[0037] Please refer to Figures 3 to 5 The stirring assembly 36 includes a rotating driving member and four stirring blades 361. The rotating driving member is arranged on the inner side of the rotating drum 34. The four stirring blades 361 are installed to rotate evenly along the circumference of the outer ring surface of the rotating drum 34, and each stirring blade is located between two adjacent partition plates 38. The rotating driving member is respectively connected to the four stirring blades 361 in transmission, and the rotating driving member drives the plurality of stirring blades 361 to rotate synchronously with the rotating drum 34. The rotating driving member includes a fixed gear 362 and a transmission part having the same number as the stirring blades 361. The axis of the fixed gear 362 coincides with the axis of the rotating drum 34, and one side of the fixed gear 362 is fixed to the liquid inlet cylinder 31. A plurality of transmission parts are evenly distributed on the outer side of the fixed gear 362. The transmission part includes a transmission gear 363 and two bevel gears 364. The transmission gear 363 is meshed with the outer side of the fixed gear 362. One of the bevel gears 364 is fixed to one side of the corresponding transmission gear 363, and the other bevel gear 364 is fixed to the rotating end of the stirring blade 361. The two bevel gears 364 are meshed, and the radius of the fixed gear 362 is at least twice that of the transmission gear 363.

[0038] It should be noted that when the above-mentioned stirring assembly 36 is in use, the drum 34 starts to rotate under the driving action of the rotating drive assembly 35. Since the fixed gear 362 is fixed to the liquid inlet cylinder 31, it will not rotate with the drum 34, while the transmission part and the stirring blade 361 rotate with the drum 34. The transmission gear 363 starts to rotate around the outer side of the fixed gear 362. The rotation of the transmission gear 363 can drive the two bevel gears 364 to rotate together, and finally the stirring blade 361 can rotate in the corresponding pretreatment chamber, so as to stir and mix the wastewater.

[0039] Please refer to Figure 5 Based on the above-mentioned stirring component 36 scheme, the present invention is further optimized, specifically: the fixed gear 362 is an incomplete gear with a non-meshing section, and the non-meshing section of the incomplete gear corresponds to the position of the liquid inlet pipe 32.

[0040] It should be noted that, with the above-mentioned optimization scheme, when the stirring blade 361 moves to the position corresponding to the liquid inlet pipe 32, the transmission gear 363 corresponding to the stirring blade 361 just moves to the non-meshing section of the incomplete gear 362, so that the transmission gear 363 no longer rotates, and the stirring blade 361 also stops rotating. In this way, when the wastewater enters the corresponding pretreatment chamber, the problem of wastewater splashing around due to the rotation of the stirring blade 361 can be avoided.

[0041] Please refer to Figure 4 , Figure 6 , Figure 7 and Figure 8 Based on the above-mentioned processing device scheme, the present invention continues to be optimized, specifically: a contraction drive assembly 37 for driving the partition plate 38 to contract toward the inner side of the rotating drum 34 is provided on the liquid inlet cylinder 31, and the contraction drive assembly 37 includes a track plate 371 and the same number of sliding wheels 372 and a return spring 375 as the partition plate 38. The track plate 371 is fixedly installed on the inner side of the liquid inlet cylinder 31, and a traction chute 373 is provided on one side of the track plate 371. A plurality of sliding wheels 372 are rollingly connected with the traction chute 373, and the traction chute 373 is connected with the rotating drum 34. The cylinder 34 is composed of a first arc groove with the center facing the inner side of the liquid inlet cylinder 31. The second arc groove is arranged near the discharge port 39. The inner side of the rotating cylinder 34 is provided with a movable groove 374 corresponding to the partition plate 38. After one end of the four sliding wheels 372 slides through the corresponding movable groove 374, it is fixed to the corresponding side of the partition plate 38. One end of the four reset springs 375 is fixed to one side of the four sliding wheels 372 in a one-to-one correspondence, and the other end of the four reset springs 375 is fixed to the inner side of the corresponding movable groove 374.

[0042] It should be noted that when the above-mentioned contraction drive assembly 37 is in use, the drum 34 starts to rotate under the driving action of the rotation drive assembly 35, and the partition plate 38 rotates with the drum 34. In the process of the partition plate 38 moving from the position of the liquid inlet pipe 32 to the position of the liquid outlet, the sliding wheel 372 first rolls along the first arc groove. When the partition plate 38 reaches the liquid outlet, the sliding wheel 372 enters the second arc groove and starts to roll along the second arc groove, and drives the corresponding partition plate 38 to gradually slide and contract toward the inside of the drum 34, and the return spring 375 The partition plate 38 is compressed synchronously. During the contraction process of the partition plate 38, the pretreatment chamber is opened quickly, and the wastewater therein can flow out quickly. In addition, the outer side of the partition plate 38 can scrape off the impurities adsorbed on its surface by cooperating with the drum 34, and the scraped impurities will fall into the treatment tank body 1 below under the action of gravity. In this way, by setting the contraction drive assembly 37, on the one hand, the wastewater discharge speed can be accelerated, so that the mixed wastewater can enter the treatment tank body 1 as soon as possible for precipitation, and on the other hand, the self-cleaning function of the partition plate 38 can be realized. After the sliding wheel 372 rolls to the deepest position of the second arc groove, it starts to drive the partition plate 38 to extend to the outside of the drum 34, and the reset spring 375 provides an outward force for the partition plate 38, so that the partition plate 38 can be smoothly extended outward until the rolling wheel enters the first arc groove again, and the telescopic action of the partition plate 38 is completed.

[0043] Please refer to Figure 3 The partition plate 38 is composed of a rectangular plate and three sealing strips. The sealing strips are fixedly installed on the side where the rectangular plate contacts the inner side of the liquid inlet cylinder 31. The sealing strips are used to seal the gap between the rectangular plate and the inner side of the liquid inlet cylinder 31.

[0044] It should be noted that the sealing strip can be made of fluororubber with good wear resistance. The sealing strip not only plays a sealing role, but also, during the rotation of the partition plate 38, the end of the sealing strip can slide in contact with the inner wall of the liquid inlet cylinder 31, thereby scraping away impurities adsorbed on the inner wall of the liquid inlet cylinder 31.

[0045] Please refer to Figure 6 The rotating drive assembly 35 includes a driving motor 351, a transmission belt 352 and two pulleys 353. The driving motor 351 is fixedly installed on the outside of the liquid inlet cylinder 31. The driving motor 351 can be a servo motor, and its rotation speed can be adjusted according to actual usage requirements. The two pulleys 353 are respectively fixed to the driving end of the driving motor 351 and the rotating end of the rotating drum 34, and the two pulleys 353 are connected by a transmission belt 352.

[0046] It should be noted that when the above-mentioned rotating drive assembly 35 is in use, the driving motor 351 can rotate, which can drive the pulley 353 connected thereto to rotate, and under the transmission cooperation of the transmission belt 352, the rotating drum 34 can eventually rotate synchronously to achieve low-speed rotation of the rotating drum 34 on the inner side of the liquid inlet cylinder 31.

[0047] Please refer to Fig. 9 The liquid inlet cylinder 31 includes a cylinder 311 with openings at both ends, two sealing plates 312 and two support frames 313. The two sealing plates 312 are detachably mounted on the two ends of the inner side of the cylinder 311, and the two ends of the outer side are rotatably connected to the two sealing plates 312. The two support frames 313 are fixedly mounted on the two ends of the liquid inlet cylinder 31, and the bottoms of the two support frames 313 are detachably mounted on the top of the treatment pool body 1.

[0048] Please refer to Figure 1 The stirring mechanism 2 is composed of three rotary stirrers, which are all installed on the top of the treatment tank body 1. The three rotary stirrers stir the wastewater in different cavities of the treatment tank body 1 respectively.

[0049] It should be noted that the mixed wastewater enters the treatment tank body 1, passes through the coagulation chamber and the sedimentation chamber of the treatment tank body 1, and is further stirred by the corresponding stirring mechanism 2 to accelerate the precipitation of impurities in the wastewater.

[0050] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
