Description
Technical Field
[0001] This invention relates to the field of wastewater treatment technology, specifically to a multi-stage wastewater treatment system for the production of fabric disinfectants. Background Technology
[0002] In the existing technology, wastewater is generated during the production of fabric disinfectants in the processes of raw material cleaning, equipment cleaning, rinsing and waste treatment. The wastewater contains harmful substances such as residual fertilizers, pesticides, dyes and auxiliaries in the raw materials, as well as high concentrations of organic matter and chemical substances left over from the chemical reaction process.
[0003] Existing technologies require multi-stage treatment of wastewater generated during the production of fabric disinfectants to eliminate impurities. Firstly, pretreatment is necessary, requiring workers to pass the wastewater through screens to remove suspended solids and large particulate impurities, protecting subsequent treatment equipment and improving efficiency. Furthermore, wastewater discharge during production may be intermittent and exhibit fluctuating composition. For example, changes in temperature, pressure, and pH during chemical reactions can affect the formation of reaction products and byproducts, thus influencing wastewater composition. Increased temperature may lead to increased concentrations of certain dissolved substances, necessitating water quality adjustment and wastewater agitation to ensure stable operation of subsequent treatment processes.
[0004] To ensure the uniformity of the wastewater's internal composition, existing technologies often use a stirring device to slowly agitate the wastewater inside the treatment equipment. However, during the agitation process, various impurities in the wastewater may accumulate on the inner wall of the treatment equipment. The various components in the wastewater may react with each other and eventually adhere to the inner wall. Furthermore, some fabric disinfectants contain certain highly corrosive components during their production process. These substances will enter the wastewater treatment equipment along with the wastewater and react with other substances during the treatment process, further corroding the inner wall of the equipment and reducing its service life.
[0005] To address this issue, we propose a multi-stage wastewater treatment system for fabric disinfectant production. Summary of the Invention

[0022] (III) Beneficial Effects
[0023] Compared with the prior art, the present invention provides a multi-stage wastewater treatment device for the production of fabric disinfectants, which has the following beneficial effects:
[0024] By simultaneously compressing the support spring and the buffer spring, when the wastewater flow decreases or the impact force exerted by the water flow on the trapezoidal block changes, the force on the support spring and the buffer spring decreases, and they tend to rebound upwards. This further buffers the filter screen through the support spring and the buffer spring, while also causing the filter screen to vibrate during use. This prevents large particles of impurities from clogging the filter screen and affecting the initial filtration of wastewater.
[0025] By setting the trapezoidal block as a stepped platform with a rounded top and the inner diameter of the stepped platform gradually increasing in the vertical direction, and simultaneously opening through holes for filtration on the trapezoidal block, it can also be regarded as part of the filtration device. The design of the trapezoidal block's arc surface, inclined surface, and flat surface can significantly improve filtration efficiency and fluid dynamic performance. The arc and inclined surface can increase the filtration area under the same volume or space conditions, thereby improving filtration efficiency, helping the fluid to flow naturally and reducing eddies and dead corners, making filtration more efficient. In addition, the structural design of the arc and inclined surface helps to distribute the impact force from the fluid more evenly, thereby enhancing the overall structure's compressive strength and durability.
[0026] By contacting the inclined surface at the top of the support rod with the bottom of the trapezoidal block and supporting it, a triangular support is formed between the support rod, the trapezoidal block and the compression rod. The triangular support can distribute the force acting on the structure to the three corners, thereby reducing the burden on individual corner points, enhancing the overall load-bearing capacity, and further dispersing the direct impact force from wastewater on the trapezoidal block.
[0027] The movement of the positioning frame and the swing block causes turbulence and flow inside the wastewater during the stirring process, resulting in a disordered flow of the liquid inside the wastewater. At this time, the swing block, which is rotated and connected inside the positioning frame, will be impacted by the disordered water flow in the wastewater during the movement. Several swing blocks will swing with different trends inside different positioning frames. During the swing, one side of the reciprocating spring is stretched and the other side of the reciprocating spring is compressed. Under the action of the water flow, the swing blocks will swing in a disordered manner, and the swing amplitude will be increased by the reciprocating spring, thereby further agitating the wastewater and accelerating the mixing of various components in the wastewater.
[0028] By using the combination of the oscillating block and the friction element, when the inner wall of the filter chamber is covered with substances that are difficult to clean, the oscillating block moves randomly, causing the friction block to move. The friction block then comes into contact with the substances attached to the inner wall of the filter chamber, and these substances exert a reverse force on the friction block, which in turn causes the oscillating block to move in the opposite direction. This process is repeated when another friction block comes into contact with the same substance. Thus, when cleaning the substances attached to the inside of the filter chamber, forces can be applied to the substances in different directions through the interaction of forces, thereby enhancing the cleaning effect and preventing corrosion of the device.
[0029] By configuring the drain pipe as a combination of two symmetrically arranged inclined pipes and a vertical pipe between them, the wastewater flowing out of the filter chamber is accelerated along the downward-sloping inclined pipe and then flows through the vertical pipe before exiting from the other inclined pipe. At this point, the wastewater is affected by the inclined pipes and flows out in a parabolic shape along the tangent of the inclined pipe outlet. Both the wastewater and flocculant splash onto the trapezoidal blocks and collide with the top surface of the trapezoidal blocks. This collision allows the wastewater and flocculant to come into full contact, thus allowing the impurities in the wastewater to be fully affected by the flocculant, forming flocculent precipitates. This process precipitates the harmful impurities in the wastewater and purifies it.
[0030] By designing the ladder-like blocks into progressively larger steps, with each level having a circular arc-shaped horizontal surface, the design increases the contact area between the liquid and solid surfaces. When wastewater and flocculant pass through these steps, each arc-shaped horizontal surface provides additional contact area, promoting greater flocculation. As the fluid passes through the arc-shaped steps, the boundary layer is continuously broken and reformed; this constant disturbance helps improve mass transfer efficiency, allowing the flocculant to better contact suspended solids in the wastewater. Furthermore, because the ladder-like blocks increase in size downwards, the wastewater encounters resistance at each step, slowing the flow rate. The circular horizontal surfaces effectively guide the fluid along a predetermined path, avoiding dead zones and short-circuiting. The regular arrangement of the ladder-like blocks helps form regular flow channels, preventing the flocs from being agitated again during settling, thus improving sedimentation efficiency.

[0057] The auxiliary sedimentation mechanism includes a sedimentation chamber 41 that is detachably and fixedly installed at the bottom of the filter chamber 11 by bolts.

One end of the diversion pipe 43 is located in the center of the sedimentation tank 41. The ladder block 45 is set in a step shape that gradually increases from top to bottom.
[0059] The multi-stage wastewater treatment equipment for fabric disinfectant production also includes a chemical treatment mechanism located below the sedimentation tank 41;
[0060] The chemical treatment mechanism includes a treatment chamber 51 that is detachably and fixedly installed at the bottom of the sedimentation chamber 41 by bolts. A discharge pipe 52 is fixedly connected to one side of the treatment chamber 51, and a bracket 53 is fixedly connected to the bottom of the treatment chamber 51.
[0061] The bottom end of the second drain pipe 42 is detachably and fixedly installed on the outer wall of the treatment chamber 51 via a connector. The second drain pipe 42 consists of two symmetrically arranged inclined pipes and a vertical pipe between the two inclined pipes.
[0062] The overall working process and principle of the above embodiments are as follows:
[0063] Initial preparation:
[0064] Staff members connect the inlet pipe 13 to the device using pipes and other connecting equipment, and then pass the wastewater generated during the production of fabric disinfectant into the device through the inlet pipe 13. The end of the drainage pipe 43 located outside the sedimentation tank 41 is fixedly connected to the output end of the external flocculant storage device.
[0065] Preliminary filtration of wastewater:
[0066] After the wastewater enters the filter chamber 11 through the inlet pipe 13, since the inlet pipe 13 is located at the center of the filter chamber 11, the wastewater will fall from the center of the filter chamber 11 onto the trapezoidal block 33, and then flow onto the filter screen 32 through the arc surface and slope of the top of the trapezoidal block 33. The wastewater will be initially filtered through the filter screen 32, which can remove suspended solids and large particulate impurities contained in the wastewater.
[0067] During the above process, the trapezoidal block 33 will be subjected to pressure and impact from the wastewater flow, which will cause the fixed frame 31, which is fixedly connected to it, to slide downward inside the filter chamber 11, and compress the support spring 312 in the process.
[0068] During the downward movement of the trapezoidal block 33, the support rod 36 and the extrusion rod 34 located below the trapezoidal block 33 will move synchronously, and the fixed block 35 fixedly connected to the support rod 36 and the extrusion rod 34 will move downward synchronously. The downward movement of the extrusion rod 34 will cause the driven member 37 fixedly connected to its bottom to move downward. Since the driven member 37 has a sliding cavity inside, and a round rod 39 is slidably connected inside the sliding cavity, and the bottom end of the round rod 39 is fixedly connected to the center of the inner wall of the filter chamber 11, the buffer spring 311 located between the round rod 39 and the driven member 37 will be compressed synchronously during the downward movement of the driven member 37.
[0069] Furthermore, the compression of the support spring 312 and the compression of the buffer spring 311 occur simultaneously. When the wastewater flow decreases or the impact force exerted by the water flow on the trapezoidal block 33 changes, the force on the support spring 312 and the buffer spring 311 decreases, and they tend to rebound upwards. Thus, the support spring 312 and the buffer spring 311 further buffer the filter screen 32, while also causing the filter screen 32 to vibrate during use, preventing large particles of impurities from clogging the filter screen 32 and affecting the initial filtration of wastewater.
[0070] It should be noted that the trapezoidal block 33 is designed as a trapezoidal platform with a rounded top, and the inner diameter of the platform gradually increases in the vertical direction. The trapezoidal block 33 is also provided with through holes for filtration, so it can also be regarded as part of the filtration device. The design of the arc surface, inclined surface and flat surface of the trapezoidal block 33 can significantly improve the filtration efficiency and fluid dynamic performance. The arc and inclined surface can increase the filtration area under the same volume or space conditions, thereby improving the filtration efficiency, helping the fluid to flow naturally and reducing eddies and dead corners, making the filtration more efficient. In addition, the structural design of the arc and inclined surface helps to distribute the impact force from the fluid more evenly, thereby enhancing the overall structural resistance and durability.
[0071] It should be further explained that the top of the support rod 36 contacts the inclined surface at the bottom of the trapezoidal block 33 and supports it, so that the support rod 36, the trapezoidal block 33 and the compression rod 34 form a triangular support. The triangular support can distribute the force acting on the structure to the three corners, thereby reducing the burden on a single corner point, enhancing the overall load-bearing capacity, and further dispersing the direct impact force from the wastewater on the trapezoidal block 33.
[0072] After the filter screen 32 has initially filtered out the impurities, the staff can open the cover 12 to quickly clean the large particles of debris remaining on the filter screen 32, so as to avoid affecting the use of the filter screen 32.
[0073] Stirring the wastewater:
[0074] During the process described above, when the driven member 37 moves down, the columnar slide rod 38, which is symmetrically fixedly connected to its outer surface, moves down synchronously. Because the columnar slide rod 38 is slidably connected to the spiral groove 22 opened on the inner wall of the rotating member 21, the columnar slide rod 38 will squeeze the spiral groove 22 during its movement, thus driving the rotating member 21 to rotate inside the filter chamber 11. As the water flow gradually decreases and the support spring 312 and the buffer spring 311 rebound, the upward movement of the columnar slide rod 38 drives the rotating member 21 to rotate in the opposite direction, thereby realizing the reciprocating rotation of the rotating member 21 inside the filter chamber 11.
[0075] During the movement of the rotating component 21, it will drive the positioning frame 24 to reciprocate inside the filter chamber 11 via the crossbar 23. Since the swing block 25 is rotatably connected to the inside of the positioning frame 24, and reciprocating springs 27 are fixedly connected between the side walls of the swing block 25 and the positioning frame 24, the wastewater will be disturbed synchronously as the positioning frame 24 and the swing block 25 rotate inside the filter chamber 11, thereby stirring the impurities inside the wastewater evenly, which is convenient for the next step of wastewater treatment.
[0076] During the aforementioned stirring process, the movement of the positioning frame 24 and the swing block 25 causes turbulence and flow within the wastewater, resulting in a disordered flow of the liquid. Simultaneously, the swing block 25, rotatably connected inside the positioning frame 24, is impacted by the disordered water flow within the wastewater. Several swing blocks 25 will swing with different trends within different positioning frames 24. During this swinging process, one side of the reciprocating spring 27 is stretched, while the other side is compressed. Under the influence of the water flow, this cycle repeats, causing the swing blocks 25 to swing disorderly, and the reciprocating springs 27 amplify the swing amplitude. This further agitates the wastewater, accelerating the mixing of various components. Since wastewater discharge during production may be intermittent and its composition may fluctuate (mainly due to factors such as discontinuous production operations, changes in process conditions, equipment cleaning and maintenance, batch differences in raw materials, and seasonal and production plan changes), the fluctuation in wastewater composition may cause the originally designed treatment process to be unable to effectively adapt to the changed water quality conditions, resulting in poor treatment effect or even treatment failure. By fully agitating the wastewater, the various components in the wastewater can be more evenly distributed, providing favorable conditions for further wastewater treatment.
[0077] It should be noted that a friction element 26 is fixedly connected to one side of the swing block 25, and the friction element 26 is set to fit against the inner wall of the filter chamber 11. Therefore, during the movement of the swing block 25, the friction element 26 will continuously contact the inner wall of the filter chamber 11, thereby generating friction and cleaning the inner wall of the filter chamber 11. This avoids the situation where some impurities adhere to the inner wall of the filter chamber 11 during the process of uniformly mixing the wastewater, causing corrosion of the filter chamber 11.
[0078] Furthermore, through the arrangement of the swing block 25 and the friction element 26, when there are substances that are difficult to clean attached to the inner wall of the filter chamber 11, the disorderly swing block 25 drives the friction block to move. Subsequently, the friction block comes into contact with the substances attached to the inner wall of the filter chamber 11. The substances will exert a reverse force on the friction block, and through the friction block, drive the swing block 25 to move in the opposite direction. Then, when another friction block comes into contact with the substances at that location, the above process is repeated. Thus, when cleaning the substances attached to the inside of the filter chamber 11, forces can be applied to the attached substances in different directions through the interaction of forces, thereby enhancing the cleaning effect of the attached substances.
[0079] Further flocculation treatment of wastewater:
[0080] The staff then opened the solenoid valve inside the drain pipe 28. The stirred wastewater would enter the sedimentation chamber 41 through the drain pipe 28 located between the filter chamber 11 and the sedimentation chamber 41. The wastewater would then mix with the drainage pipe 43 connected to the external flocculant storage device inside the sedimentation chamber 41. Since the end of the drainage pipe 43 located inside the sedimentation chamber 41 is directly above the center of the ladder block 45, the flocculant would fall directly onto the top center of the ladder block 45.
[0081] In the above process, since the drain pipe 28 consists of two axially symmetrically arranged inclined pipes and a vertical pipe between the two inclined pipes, the wastewater flowing out of the filter chamber 11 will accelerate along the inclined pipes that are inclined downwards and then flow out through the vertical pipe, and then out through the other inclined pipe. At this time, the wastewater will be affected by the inclined pipes and flow out in a parabolic shape along the tangent of the inclined pipe outlet, and spray towards the center of the sedimentation chamber 41, mix with the flocculant flowing out of the drainage pipe 43, and come into contact with the ladder block 45.
[0082] Furthermore, during the contact process between wastewater and flocculant, both wastewater and flocculant will splash onto the ladder-shaped block 45 and collide with the top surface of the ladder-shaped block 45. The collision allows the wastewater and flocculant to come into full contact, thereby allowing the impurities in the wastewater to be fully affected by the flocculant, forming flocculent precipitates, which facilitates further treatment of the wastewater.
[0083] It should be noted that the ladder-shaped blocks 45 gradually increase in size from top to bottom, and each level of the ladder-shaped blocks 45 has a circular arc-shaped horizontal surface. The design of the ladder-shaped blocks 45 makes each step arc-shaped, which increases the contact area between the liquid and the solid surface. When wastewater and flocculant pass through these steps, each arc-shaped horizontal surface provides additional contact area, thereby promoting more flocculation reactions. As the fluid passes through the arc-shaped steps, the boundary layer is constantly broken and reformed. This continuous disturbance helps improve mass transfer efficiency, allowing the flocculant to better contact the suspended solids in the wastewater. Furthermore, because the ladder-shaped blocks 45 gradually increase in size downwards, the wastewater encounters a certain resistance when flowing through each step, thereby slowing down the flow velocity. The circular arc-shaped horizontal surfaces can effectively guide the fluid to flow along the set path, avoiding dead zones and short-circuiting phenomena. The regular arrangement of the ladder-shaped blocks 45 helps to form regular flow channels, preventing the flocs from being agitated again by the water flow during the settling process, thus improving sedimentation efficiency.
[0084] As wastewater and flocculant are injected and sedimentation is completed in sedimentation chamber 41, the staff will open the solenoid valve inside drain pipe 42 to discharge the secondary treated wastewater into treatment chamber 51 through drain pipe 42.
[0085] During the above process, the flocculent impurities generated by the reaction between wastewater and flocculant inside the sedimentation tank 41 will fall onto the sludge collection plate 44 located at the bottom of the trapezoidal block 45 along the arc surface of the trapezoidal block 45. After the wastewater treatment is completed, the staff can manually hold the handle extending from the outer surface of the worm gear 46 and make the worm gear 46 rotate. At this time, the sludge collection plate 44, which is fixedly connected to the worm gear 46, will rotate synchronously with the connection point between the worm gear 46 and the sedimentation tank 41 as the fulcrum. This allows the sediment on the sludge collection plate 44 to be poured into the treatment tank 51, thereby cleaning the impurities on the sludge collection plate 44 and quickly cleaning the generated flocculent sediment.
[0086] During the above process, the worm wheel 46 and the worm 47 mesh, and the worm 47 rotates under the action of the worm wheel 46. When the worm wheel 46 stops rotating, the worm wheel 46 and the worm 47 have self-locking properties, which restricts the position of the worm wheel 46 through the worm 47, and further restricts the position of the sludge collecting disc 44, thereby controlling the tilt angle of the sludge collecting disc 44 during the cleaning process and fixing its position, so as to clean the impurities in the sludge collecting disc 44 more quickly.
[0087] Further treatment of wastewater:
[0088] Wastewater entering the treatment chamber 51 will undergo further treatment within the chamber. By adding anaerobic and aerobic bacteria to the treatment chamber 51, the wastewater can be further degraded by microorganisms. After treatment, the wastewater can be discharged from the device through the discharge pipe 52, thus achieving a multi-stage treatment effect.
