Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically, to a device for treating wastewater from the dyeing of elastic fibers. Background Technology

[0002] In the process of wastewater treatment and reuse, it is necessary to treat the wastewater from dyeing elastic fibers to achieve reuse and reduce the waste of water resources. The biological process in the wastewater treatment device mainly utilizes the biofilm method. Through the metabolic activities of microorganisms, the pollutants in the wastewater are efficiently removed and the resources are utilized. Microorganisms decompose large organic molecules such as dyes, auxiliaries, and fiber fragments in the wastewater into smaller molecules by secreting enzymes such as proteases, lipases, and oxidases.

[0003] Among existing publicly available documents, patent publication number CN214735212U discloses a wastewater and waste gas treatment device. This technology utilizes a biofilm installed inside a waste gas treatment tank, several second liquid distributors, second nozzles mounted on the second liquid distributors, a plant sap inlet pipe connected to the second liquid distributors, an exhaust port at the top of the waste gas treatment tank, and a second drain pipe at the bottom of the waste gas treatment tank. This utility model offers good treatment results and prevents filter clogging, possessing high practical and promotional value in the field of environmental protection technology. However, this patent has the following drawbacks.

[0004] When treating wastewater from elastic fiber dyeing, a microbial substrate needs to be attached to the biofilm. Although the biofilm has a certain degree of elasticity and needs to be limited within a specified range, changes in the influent volume of the elastic fiber dyeing wastewater, sometimes requiring the treatment of large volumes while maintaining high flow rates, can lead to significant deformation of the biofilm due to fluid impact. Excessive deformation can damage the biofilm, making it difficult to self-protect against the impact. Consequently, the biofilm is easily damaged and its durability deteriorates during the treatment of elastic fiber dyeing wastewater. Summary of the Invention

[0026] In a preferred embodiment, a positioning frame is slidably installed on the inner wall of the support frame and on the other side of the biofilm. Both positioning frames are fixedly connected to the biofilm, and a microbial base layer is provided between the two positioning frames.

[0027] The technical effects and advantages of this invention are as follows:

[0028] 1. This invention utilizes a reset protection mechanism. When excessive deformation of the biofilm occurs, the guide bar drives the support column and itself to move to the left along the inner wall of the frame, simultaneously pushing the reset bar and ring bar to the left. This causes the ring bar to compress the circumference of the biofilm, the branch bar to support multiple corner positions on the edge, and the curved bar to compress the curved area of ​​the support frame. This achieves large-area leftward deformation reset of the biofilm, preventing excessive deformation and restoring the biofilm within a specified elastic range. Based on the changes in the flow rate and impact force of the elastic fiber dyeing waste liquid, the invention dynamically protects the biofilm by resetting it, avoiding damage caused by excessive deformation and improving the durability of the biofilm.

[0029] 2. This invention employs a deformation detection component. When the biofilm deforms to the right, it sequentially drives the connecting column and connecting block to move to the right, causing the bottom end of the elastic rope to move to the right. The top end of the rope pulls the sensing end of the tension sensor. Once the tension value exceeds the threshold set by the controller, it indicates that the biofilm is impacted by a large flow of elastic fiber dyeing waste liquid, resulting in excessive deformation of the biofilm. At this time, the controller can immediately activate the electric cylinder to intervene and achieve reset protection. It can monitor the deformation state of the biofilm in real time and accurately, detect excessive deformation of the biofilm in a timely manner, and respond quickly, effectively protecting the biofilm, avoiding damage to the biofilm due to excessive deformation, and extending the service life of the biofilm.

[0030] 3. The present invention uses a drive component to guide the output end of the electric cylinder to slide down along the inner wall of the processing box, causing the triangular plate, the inclined pressure frame and the slide groove to move down. In this way, the sliding shaft slides along the inner wall of the slide groove, and at the same time, the sliding shaft drives the guide bar to move to the left. By using the linear motion of the electric cylinder, the guide bar moves laterally to the left, thereby achieving precise power control for the deformation and restoration of the biofilm, and avoiding the problem of excessive deformation and damage to the biofilm.

[0031] In summary, through the interaction of the above-mentioned multiple functions, firstly, when the tension value sensed by the tension sensor exceeds the tension threshold set by the controller, it is known that excessive deformation of the biofilm has begun. Secondly, the sliding shaft drives the guide bar to move to the left. Finally, a large-area leftward displacement and deformation of the biofilm is restored, preventing excessive deformation and damage to the biofilm. In conclusion, based on the changes in the impact force of the elastic fiber dyeing wastewater flow, the biofilm can be protected and restored, avoiding excessive deformation and damage, and improving the durability of the biofilm.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] like Figure 1 - Figure 9 The device for treating wastewater from dyeing elastic fibers is shown. The device is equipped with a reset protection mechanism, a deformation detection component, and a drive component. The various mechanisms and components are configured to protect and reset the biofilm 3 according to the changes in the flow rate and impact force of the wastewater from dyeing elastic fibers, so as to avoid excessive deformation of the biofilm 3 and damage, thereby improving the durability of the biofilm 3. The specific structural settings of each mechanism and component are as follows.

[0044] In this embodiment, as Figure 1 - Figure 4As shown, the inner wall of the treatment box 1 is fixedly connected to two support frames 2, and a biofilm 3 is provided between the two support frames 2. A reset protection mechanism is provided on one side of the biofilm 3. The reset protection mechanism includes: a reset strip 4, located on one side of the biofilm 3, with a ring strip 5 fixedly connected to the top of the reset strip 4; multiple branch strips 6, all circumferentially distributed and fixedly connected to the outer wall of the ring strip 5, with multiple curved strips 7 fixedly connected to the inner wall of the ring strip 5; a support column 8, fixedly connected to one side of the reset strip 4, with a guide strip 9 fixedly connected to the outer wall of the support column 8 for guiding and limiting; a sleeve 10 is slidably connected to the outer wall of the guide strip 9, and the sleeve 10 is used to guide the slide of the support column 8; a deformation detection component is provided on one side of one of the support frames 2, and a drive component is installed on one side of the guide strip 9. When the deformation detection component detects that the deformation threshold of the biofilm 3 exceeds the set threshold, the drive component is used to drive the guide strip 9 to move to the left. The biofilm 3 is made of polyethylene elastic material, and there is a gap between the ring strip 5 and the biofilm 3. The guide bar 9 is fixedly connected to the reset bar 4, and multiple curved bars 7 are also fixedly connected to the reset bar 4. One end of the sleeve 10 is fixedly connected to the treatment box 1. This is so that if the deformation threshold of the biofilm 3 exceeds a set threshold, the biofilm 3 will be subjected to the impact force of a large flow of elastic fiber dyeing waste liquid, causing excessive deformation of the biofilm 3. The drive assembly is used to move the guide bar 9 to the left, which in turn moves the support column 8 to the left. Both the support column 8 and the guide bar 9 move the reset bar 4 to the left, causing the ring bar 5 to be pressed against the circumference of the biofilm 3. Multiple branch bars 6 can support the biofilm 3 at the edge corners, and multiple curved bars 7 can provide compression support for the support frame 2 in various curved areas. This allows for large-area leftward deformation and reset of the biofilm 3, ensuring dynamic reset protection of the biofilm 3 based on the impact force changes of the elastic fiber dyeing waste liquid flow rate, thus preventing excessive deformation and damage to the biofilm 3.

[0045] In this embodiment, as Figure 5 - Figure 6As shown, the deformation detection assembly includes: a support block 11, fixedly connected to one side of one of the support frames 2, with a tension sensor 12 fixedly connected to the lower inclined surface of the support block 11; an elastic rope 13, with its top end fixedly connected to the tension sensing end of the tension sensor 12, and a connecting block 14 fixedly connected to its bottom end; a connecting post 15, fixedly connected to the bottom end of the connecting block 14, and fixedly connected to the biofilm 3. The connecting post 15 is used to pull the connecting block 14 when the biofilm 3 deforms. The controller 27 is electrically connected to the tension sensor 12. The elastic rope 13 is made of polyethylene elastic material, and the connecting block 14 and the connecting post 15 are both made of stainless steel. The center point of the elastic rope 13 and the center point of the connecting block 14 are on the same inclined line, and the cross-sectional shape of the connecting block 14 is circular. So that the deformation of the biofilm 3 to the right will cause the connecting column 15 to deform to the right. Under the action of the deformation tension, the connecting block 14 will cause the bottom end of the elastic rope 13 to move to the right. The top end of the elastic rope 13 pulls the tension sensing end of the tension sensor 12. The support block 11 provides support force to the upper surface of the tension sensor 12. When the tension value sensed by the tension sensor 12 exceeds the tension threshold set by the controller 27, the electric cylinder 20 will be activated immediately by the controller 27, so as to reset and protect the over-deformed biofilm 3 in time.

[0046] In this embodiment, as Figure 7 - Figure 8 As shown, the drive assembly includes: a sliding shaft 16, fixedly connected to one side of the guide bar 9, with a slidable pressure frame 17 slidably connected to the outer wall of the guide bar 9; a sliding groove 18, formed on the inner wall of the slidable pressure frame 17, the sliding groove 18 being inclined and slidably connected to the sliding shaft 16; a triangular plate 19, fixedly connected to the upper inclined surface of the slidable pressure frame 17, the triangular plate 19 being used to provide vertical extrusion force to the slidable pressure frame 17; an electric cylinder 20, installed on the upper surface of the processing box 1, the output end of the electric cylinder 20 being slidably connected to the processing box 1, and the output end of the electric cylinder 20 being fixedly connected to the triangular plate 19, the electric cylinder 20 being electrically connected to the controller 27, a limit ring 21 being slidably connected to one side of the slidable pressure frame 17, and the limit ring 21 being fixedly connected to the sliding shaft 16. So that the output end of the electric cylinder 20 can slide down along the inner wall of the processing box 1, so that the triangular plate 19 will drive the inclined pressure frame 17 to move down. Under the action of the inclined pressure frame 17, the sliding shaft 16 slides along the inner wall of the slide groove 18, ensuring that the sliding shaft 16 drives the guide bar 9 to move to the left, so that the guide bar 9 can move to the left in time.

[0047] In this embodiment, as Figure 1 - Figure 2As shown, a filter screen 22 is provided on the other side of the support frame 2. One end of the treatment tank 1 is fixedly connected to an outlet pipe 24. An activated adsorption layer 23 is fixedly connected to one side of the support frame 2 near the outlet pipe 24. A pump 25 is fixedly connected to one end of the outlet pipe 24, and the pump 25 is electrically connected to the controller 27. An inlet pipe 26 is fixedly installed at the other end of the treatment tank 1. The activated adsorption layer 23 is made of activated carbon, and the center point of the inlet pipe 26 is higher than the center point of the outlet pipe 24. This allows a large amount of elastic fiber dyeing waste liquid to be transported into the treatment tank 1 through the inlet pipe 26. Impurities are filtered by the filter screen 22, and the elastic fiber dyeing waste liquid is subjected to microbial degradation treatment by the microbial substrate 28. After adsorption by the activated adsorption layer 23, the waste liquid is guided to the outlet pipe 24, and the pump 25 causes the outlet pipe 24 to transport the treated elastic fiber dyeing waste liquid out for the next step of treatment. This achieves wastewater treatment and recycling of elastic fiber dyeing waste liquid.

[0048] In this embodiment, as Figure 9 As shown, a positioning frame 29 is slidably installed on the inner wall of the support frame 2 and on the other side of the biofilm 3. Both positioning frames 29 are fixedly connected to the biofilm 3. A microbial base layer 28 is provided between the two positioning frames 29 so that the positioning frames 29 can be supported by the support frame 2. The positioning frames 29 support the biofilm 3, ensuring that the biofilm 3 stably supports the microbial base layer 28. The microbial base layer 28 can achieve microbial treatment of the elastic fiber dyeing waste liquid.

[0049] The working principle of the elastic fiber dyeing wastewater treatment device of the present invention is as follows:

[0050] Firstly, in the treatment of elastic fiber dyeing wastewater according to this invention, during the wastewater treatment and recycling process, the inlet pipe 26 needs to be connected to the pipeline transporting the elastic fiber dyeing wastewater, while the output end of the pump 25 is connected to the output pipeline. Thus, a large amount of elastic fiber dyeing wastewater is transported to the treatment tank 1 through the inlet pipe 26. Impurities are filtered through the filter screen 22, and the wastewater undergoes microbial degradation treatment through the microbial substrate 28. It then flows through the biofilm 3 to the activated adsorption layer 23 for adsorption, and after adsorption, it flows through the activated adsorption layer 23 to the outlet pipe 24. The pump 25 then transports the treated elastic fiber dyeing wastewater through the outlet pipe 24 for the next processing step. The large amount of elastic fiber dyeing wastewater exerts pressure on the microbial substrate 28, causing the microbial substrate 28 to compress the biofilm 3. The positioning frame 29 is supported by the support frame 2, and the positioning frame 29 supports the biofilm 3. The biofilm 3 is subjected to a large amount of elastic fiber dyeing waste liquid fluid impact force, causing the right side of the biofilm 3 to deform and stretch. This deformation and stretching of the biofilm 3 can form a channel structure, increase the surface area to volume ratio, promote the diffusion and absorption of nutrients such as carbon source and oxygen, thereby improving the activity of microorganisms. Therefore, the biofilm 3 needs a certain deformation range.

[0051] Secondly, during deformation detection, the rightward deformation of the biofilm 3 causes the connecting column 15 to deform to the right, which in turn causes the connecting block 14 to deform to the right, which in turn causes the bottom end of the elastic rope 13 to deform to the right. The top of the elastic rope 13 pulls the tension sensing end of the tension sensor 12, which in turn supports the support block 11 through the support frame 2. The support block 11 provides support force to the upper surface of the tension sensor 12, and the tension sensor 12 begins to sense the tension value of the elastic rope 13. When the tension value sensed by the tension sensor 12 exceeds the tension threshold set by the controller 27, the biofilm 3 will be subjected to the impact force of a large flow of elastic fiber dyeing waste liquid, causing the biofilm 3 to begin to deform excessively. In this case, the controller 27 immediately activates the electric cylinder 20.

[0052] Then, when the present invention is driven, the processing box 1 provides support to the outer shell of the electric cylinder 20, and the output end of the electric cylinder 20 slides down along the inner wall of the processing box 1. At the same time, the output end of the electric cylinder 20 drives the triangular plate 19 to move downward, and the triangular plate 19 drives the inclined pressure frame 17 to move downward. The inclined pressure frame 17 drives the slide groove 18 to move downward. The slide groove 18 inside the inclined pressure frame 17 can squeeze the slide shaft 16 in an inclined state. Under the action of the inclined pressure of the inner wall of the inclined pressure frame 17, the slide shaft 16 slides along the inner wall of the slide groove 18. At the same time, the slide shaft 16 drives the limiting ring 21 to slide along the inclined pressure frame 17. In this way, the slide shaft 16 begins to drive the guide bar 9 to move to the left.

[0053] Finally, during the reset protection process, the guide bar 9 drives the support column 8 to move to the left. The support column 8 moves to the left along the inner wall of the sleeve 10, and the guide bar 9 also moves to the left along the inner wall of the sleeve 10. Both the support column 8 and the guide bar 9 drive the reset bar 4 to move to the left. The reset bar 4 drives the ring bar 5 to move to the left, and the ring bar 5 presses against the circumference of the biofilm 3. At the same time, the ring bar 5 drives multiple branch bars 6 to press against the biofilm 3, and the multiple branch bars 6 can provide support for the biofilm 3 at the edge corners. Simultaneously, the ring bar 5 drives multiple curved bars 7 to press against the biofilm 3, so that the multiple curved bars 7 can provide compression support for the support frame 2 in various curved areas. In this way, the biofilm 3 begins to deform and reset to the left, avoiding excessive deformation of the biofilm 3. This allows the biofilm 3 to undergo large-area leftward deformation and reset, thereby driving the connecting column 15 to move to the left. The connecting column 15 drives the connecting block 14 to move to the left, and the connecting block 14 no longer exerts a large tension on the elastic rope 13. When the tension value of the elastic rope 13 on the tension sensor 12 decreases, and the tension value sensed by the tension sensor 12 drops to the pressure value range set by the controller 27, the electric cylinder 20 is shut off by the controller 27. At this time, the biofilm 3 can be reset within the specified deformation range, avoiding excessive deformation damage to the biofilm 3 when subjected to the impact force of a large flow of elastic fiber dyeing waste liquid. Based on the change in impact force according to the flow rate of elastic fiber dyeing waste liquid, dynamic reset protection of the biofilm 3 is achieved, improving the durability of the biofilm 3.
