Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to multi-stage wastewater treatment equipment for the production of fabric disinfectants. Background Art

[0002] In the prior art, wastewater is generated during the production of fabric disinfectants in the process of raw material cleaning, equipment cleaning, flushing, and waste treatment. The wastewater contains harmful substances such as fertilizers and pesticides, dye additives, etc. remaining in the raw materials, as well as high-concentration organic matter and chemical substances retained during the chemical reaction process;

[0003] The existing technology requires multi-stage treatment of the wastewater generated during the production of fabric disinfectants to eliminate impurities contained in the wastewater. First, the wastewater needs to be pretreated, and the staff needs to remove the wastewater through a screen, etc. The main purpose is to remove suspended matter and large particle impurities to protect subsequent treatment equipment and improve treatment efficiency. In addition, the discharge of wastewater during the production process may be intermittent and have fluctuating composition. For example, changes in temperature, pressure, pH value and other conditions during the chemical reaction process will affect the formation of reaction products and the generation of by-products, thereby affecting the composition of the wastewater. The increase in temperature may lead to an increase in the concentration of certain dissolved substances. Therefore, water quality adjustment is required, and the wastewater needs to be stirred to ensure the stable operation of the subsequent treatment process.

[0004] In order to ensure the uniformity of the internal components of the wastewater, the existing technology often uses a stirring device to slowly stir the wastewater inside the treatment equipment. However, during the stirring process, the various impurities contained in the wastewater may accumulate on the inner wall of the treatment equipment, and the various components contained in the wastewater may react with each other and eventually adhere to the inner wall. In addition, some fabric disinfectants contain certain highly corrosive components during the 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 device and reducing the service life of the treatment equipment.

[0005] In this regard, we propose a multi-stage wastewater treatment equipment for the production of fabric disinfectants to solve the above problems. 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 compressing the support spring and the buffer spring simultaneously, when the wastewater flow decreases or the impact force exerted by the water flow on the trapezoidal block changes, the force acting on the support spring and the buffer spring decreases, and there is a tendency to rebound upward, thereby further buffering the filter through the support spring and the buffer spring, and at the same time making the filter vibrate during use, preventing large particles of impurities from clogging the filter and affecting the initial filtration of the wastewater.

[0025] By setting the trapezoidal block as a terrace with an arc-shaped curved surface at the top, and the inner diameter of the terrace gradually increasing in the vertical direction, a through hole for filtering is simultaneously opened on the trapezoidal block, so it can also be regarded as a part of the filtering device. The design of the arc surface, inclined surface and plane of the trapezoidal block can significantly improve the filtering efficiency and fluid dynamics performance. The arc and inclined surface can increase the filtering area under the same volume or space conditions, thereby improving the filtering efficiency, facilitating the natural flow of the fluid and reducing eddy currents and dead corners, making the filtration more efficient. In addition, the structural design of the arc surface and inclined surface helps to more evenly distribute the impact force from the fluid, thereby enhancing the pressure resistance and durability of the overall structure.

[0026] The top of the support rod is in contact with the inclined surface of the bottom end of the trapezoidal block and supports it, so that a triangular support is formed between the support rod, the trapezoidal block and the extrusion rod. The triangular support can disperse the force acting on the structure to three corners, thereby reducing the burden on a single corner point and enhancing the overall bearing capacity, thereby further dispersing the direct impact force from the wastewater on the trapezoidal block.

[0027] Through the movement of the positioning frame and the swing block, turbulence and turbulence will appear in the wastewater during the stirring process, so that the liquid in the wastewater will flow in a disordered state. At this time, the swing block connected to 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 in different positioning frames, and stretch the reciprocating spring on one side and compress the reciprocating spring on the other side during the swinging process. Under the action of the water flow, the swing block will swing back and forth in a disordered manner, and the swing amplitude will be increased by the reciprocating spring, so as to further stir the wastewater and accelerate the mixing of various components in the wastewater.

[0028] Through the arrangement of the swing block and the friction part, when there is material that is difficult to clean attached to the inner wall of the filter bin, the disorderly swinging swing block drives the friction block to move, and then the friction block contacts the material attached to the inner wall of the filter bin. The material will apply a reverse force to the friction block, and drive the swing block to move in the opposite direction through the friction block. Then, when another friction block contacts the material at that location, the above process is repeated. Therefore, when cleaning the attached material inside the filter bin, forces in different directions can be applied to the attached material through the interaction of forces, thereby enhancing the cleaning effect on the attached material and avoiding corrosion of the device.

[0029] By configuring the drain pipe to consist of two axially symmetrically arranged inclined pipes and a vertical pipe arranged between the two inclined pipes, the wastewater will be accelerated along the inclined pipe inclined downward when flowing out of the filter bin, and will flow out along the vertical pipe and then from another inclined pipe. At this time, the outflowing wastewater will be affected by the inclined pipe, and will flow out in a parabolic shape in the direction of the inclined pipe and along the tangent of the inclined pipe outlet. The wastewater and flocculant will both splash on the ladder block and collide with the top surface of the ladder block. The collision can make the wastewater fully contact with the flocculant, so that the impurities in the wastewater can be fully affected by the flocculant to form flocculent precipitated impurities, thereby precipitating harmful impurities contained in the wastewater and purifying the wastewater.

[0030] By setting the ladder blocks to be gradually enlarged from top to bottom, and the horizontal surface of each layer of the ladder blocks is arc-shaped, the design of the ladder blocks makes each layer of steps present an arc shape, which increases the contact area between the liquid and the solid surface. When the wastewater and flocculant pass through these steps, each arc-shaped horizontal surface can provide additional contact area, thereby promoting more flocculation reactions. When the fluid passes through the arc-shaped steps, the boundary layer will be constantly interrupted and re-formed. This constant disturbance helps to improve the mass transfer efficiency, so that the flocculant can better contact with the suspended matter in the wastewater. Because the ladder blocks gradually increase downward, the wastewater will encounter a certain resistance when flowing through each step, thereby slowing down the flow rate. The arc-shaped horizontal surface can effectively guide the fluid to flow along the set path, avoiding dead corners and short-flow phenomena. The regular arrangement of the ladder blocks helps to form a regular flow channel, so that the floccules are prevented from being stirred up again by the water flow during the sedimentation process, which can improve the sedimentation efficiency.

The ladder block 45 is arranged to be a step that gradually increases from top to bottom.

[0059] The multi-stage wastewater treatment equipment for the production of fabric disinfectants also includes a chemical treatment mechanism disposed below the sedimentation bin 41;

[0060] The chemical treatment mechanism includes a treatment chamber 51 detachably fixed to 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 drainage pipe 42 is detachably fixedly mounted on the outer wall of the processing chamber 51 through a connector, and the second drainage pipe 42 is composed of two axisymmetrically arranged inclined pipes and a vertical pipe arranged between the two inclined pipes.

[0062] The working process and principle of the overall content of the above embodiment are as follows:

[0063] Initial preparation:

[0064] The staff is fixedly connected with the water inlet pipe 13 through a connecting device such as a pipeline, and the wastewater generated during the production of the fabric disinfectant is passed into the device through the water inlet pipe 13. One end of the drainage pipe 43 disposed outside the sedimentation bin 41 is fixedly connected to the output end of the external flocculant storage device;

[0065] Initial filtration of wastewater:

[0066] After the wastewater enters the filter bin 11 through the water inlet pipe 13, since the water inlet pipe 13 is arranged at the center position above the filter bin 11, the wastewater will fall onto the trapezoidal block 33 from the center above the filter bin 11, and then flow onto the filter screen 32 through the arc surface and the inclined surface at the top of the trapezoidal block 33, and the wastewater will be preliminarily filtered through the filter screen 32, so that the suspended matter and large particle impurities contained in the wastewater can be removed;

[0067] In the above process, the trapezoidal block 33 is subjected to the pressure and impact force from the wastewater flow, thereby driving the fixed frame 31 fixedly connected thereto to slide downward inside the filter bin 11, and in the process, compressing the support spring 312;

[0068] During the downward movement of the trapezoidal block 33, the support rod 36 and the extrusion rod 34 arranged below the trapezoidal block 33 will be driven to move synchronously, and the fixed block 35 fixedly connected to the support rod 36 and the extrusion rod 34 will be driven to move downward synchronously. The downward movement of the extrusion rod 34 will prompt the follower 37 fixedly connected to its bottom to move downward. Since a sliding cavity is provided inside the follower 37, 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 position of the inner wall of the filter bin 11, the buffer spring 311 arranged between the round rod 39 and the follower 37 will be compressed synchronously during the downward movement of the follower 37.

[0069] The compression of the support spring 312 and the compression of the buffer spring 311 are carried out synchronously. When the wastewater flow decreases or the impact force exerted by the water flow on the trapezoidal block 33 changes, the force acting on the support spring 312 and the buffer spring 311 decreases, and there is a tendency to rebound upward, thereby further buffering the filter screen 32 through the support spring 312 and the buffer spring 311, and at the same time making the filter screen 32 vibrate during use, to prevent large particles of impurities from blocking the filter screen 32 and affecting the initial filtration of the wastewater.

[0070] It should be noted that the trapezoidal block 33 is configured as a terrace with an arc-shaped curved surface at the top, and the inner diameter of the terrace gradually increases in the vertical direction. A through hole for filtering is simultaneously opened on the trapezoidal block 33, so it can also be regarded as a part of the filtering device. The design of the arc surface, inclined surface and plane of the trapezoidal block 33 can significantly improve the filtering efficiency and fluid dynamics performance. The arc and inclined surface can increase the filtering area under the same volume or space conditions, thereby improving the filtering efficiency, facilitating the natural flow of the fluid and reducing eddy currents and dead corners, making the filtration more efficient. In addition, the structural design of the arc surface and inclined surface helps to more evenly distribute the impact force from the fluid, thereby enhancing the pressure resistance and durability of the overall structure.

[0071] It should be further explained that the top of the support rod 36 contacts the inclined surface of the bottom end of the trapezoidal block 33 and supports it, so that a triangular support is formed between the support rod 36, the trapezoidal block 33 and the extrusion rod 34. The triangular support can disperse the force acting on the structure to three corners, thereby reducing the burden of a single corner point and enhancing the overall bearing capacity, thereby further dispersing the direct impact force from the wastewater on the trapezoidal block 33;

[0072] After the filter 32 has initially filtered out the impurities, the staff can open the shielding cover 12 to quickly clean up the large particles of debris remaining on the filter 32 to avoid affecting the use of the filter 32.

[0073] Mixing of wastewater:

[0074] During the above process, when the follower 37 moves downward, the columnar slide bar 38 symmetrically fixedly connected to its outer surface will move downward synchronously. Because the columnar slide bar 38 is slidably connected to the spiral groove 22 opened on the inner wall of the rotating member 21, the columnar slide bar 38 will squeeze the spiral groove 22 during the movement to drive the rotating member 21, so that the rotating member 21 rotates inside the filter bin 11, and when the water flow gradually decreases and the support spring 312 and the buffer spring 311 rebound, the rotating member 21 is driven to rotate in the opposite direction by moving upward of the columnar slide bar 38, thereby realizing the reciprocating rotation of the rotating member 21 inside the filter bin 11.

[0075] During the movement of the rotating member 21, the horizontal bar 23 drives the positioning frame 24 to reciprocate inside the filter bin 11. Since the swing block 25 is rotatably connected to the inside of the positioning frame 24, and a reciprocating spring 27 is fixedly connected between the side walls of the swing block 25 and the positioning frame 24, as the positioning frame 24 and the swing block 25 rotate inside the filter bin 11, the wastewater will be disturbed synchronously, thereby evenly stirring the impurities inside the wastewater, which is convenient for the next step of wastewater treatment.

[0076] During the above stirring process, with the movement of the positioning frame 24 and the swing block 25, turbulence and turbulence will occur inside the wastewater during the stirring process, causing the liquid inside the wastewater to flow in a disordered state. At this time, the swing block 25 that is rotatably connected to the inside of the positioning frame 24 will be simultaneously impacted by the disordered water flow in the wastewater during the movement. Several swing blocks 25 will swing with different trends inside different positioning frames 24, and in the process of swinging, the reciprocating spring 27 on one side is stretched and the reciprocating spring 27 on the other side is compressed. Under the action of the water flow, the swing block 25 swings back and forth in a disordered manner, and the swing amplitude is increased by the reciprocating spring 27. Thereby further agitating the wastewater and accelerating the mixing of various components in the wastewater. Since the discharge of wastewater in the production process may be intermittent and the composition fluctuates (mainly due to the discontinuity of production operations, changes in process conditions, equipment cleaning and maintenance, differences in raw material batches, and seasonal and production plan changes), the volatility of 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 effects or even treatment failure. By fully stirring the wastewater, the various components in the wastewater can be more evenly distributed, providing favorable conditions for the subsequent further treatment of the wastewater.

[0077] It should be noted that a friction member 26 is fixedly connected to one side of the swing block 25, and the friction member 26 is configured to fit the inner wall of the filter bin 11. Therefore, during the movement of the swing block 25, the friction member 26 will synchronously and continuously contact the inner wall of the filter bin 11, thereby generating friction therewith, cleaning the inner wall of the filter bin 11, thereby preventing some impurities from adhering to the inner wall of the filter bin 11 during the process of evenly stirring the wastewater, causing corrosion of the filter bin 11.

[0078] And through the setting of the swing block 25 and the friction member 26, when the inner wall of the filter bin 11 is attached with substances that are difficult to clean, the disorderly swinging swing block 25 drives the friction block to move, and then the friction block contacts the substances attached to the inner wall of the filter bin 11. The substances will apply a reverse force to the friction block, and drive the swing block 25 to move in the reverse direction through the friction block. Then, when another friction block contacts the substances at that location, the above process is repeated. Therefore, when cleaning the substances attached to the inside of the filter bin 11, forces in different directions can be applied to the attached substances through the interaction of forces, thereby enhancing the cleaning effect of the attached substances.

[0079] Further flocculation treatment of wastewater:

[0080] Then the staff opens the solenoid valve inside the drain pipe 28. The wastewater after stirring will enter the sedimentation tank 41 through the drain pipe 28 arranged between the filtration tank 11 and the sedimentation tank 41, and be mixed inside the sedimentation tank 41 and through the drainage pipe 43 connected to the external flocculant storage device. Since one end of the drainage pipe 43 inside the sedimentation tank 41 is located directly above the center of the ladder block 45, the flocculant will directly fall on the top center of the ladder block 45.

[0081] In the above process, since the drain pipe 28 is composed of two axially symmetrically arranged inclined pipes and a vertical pipe arranged between the two inclined pipes, the wastewater flowing out of the filter tank 11 will be accelerated along the inclined pipe tilted downward, and along the vertical pipe, and then flow out from the other inclined pipe. At this time, the outflowing wastewater will be affected by the inclined pipe, and flow out in a parabolic shape in the direction of the inclined pipe and along the tangent of the inclined pipe outlet, and sprayed toward the center of the sedimentation tank 41, mixed with the flocculant flowing out of the drainage pipe 43, and contacted on the ladder block 45.

[0082] In the process of contact between the wastewater and the flocculant, both the wastewater and the flocculant will splash on the ladder block 45 and collide with the top surface of the ladder block 45. The collision can make the wastewater and the flocculant fully contact, so that the impurities in the wastewater can be fully affected by the flocculant to form flocculent precipitated impurities, which is convenient for further treatment of the wastewater.

[0083] It should be noted that the ladder block 45 is in the shape of a step that gradually increases from top to bottom, and the horizontal surface of each layer of the ladder block 45 is arc-shaped. The design of the ladder block 45 makes each layer of the step present an arc shape, which increases the contact area between the liquid and the solid surface. When the wastewater and flocculant pass through these steps, each arc-shaped horizontal surface can provide additional contact area, thereby promoting more flocculation reactions. When the fluid passes through the arc-shaped steps, the boundary layer will be continuously interrupted and re-formed. This continuous disturbance helps to improve the mass transfer efficiency, so that the flocculant can better contact with the suspended matter in the wastewater. Since the ladder block 45 increases step by step downward, the wastewater will be subject to a certain resistance when flowing through each step, thereby slowing down the flow rate. The arc-shaped horizontal surface can effectively guide the fluid to flow along the set path, avoiding dead corners and short-flow phenomena. The regular arrangement of the ladder block 45 helps to form a regular flow channel, so that the flocculent body is prevented from being stirred up again by the water flow during the sedimentation process, which can improve the sedimentation efficiency.

[0084] With the injection of wastewater and flocculant, and the completion of sedimentation in the sedimentation bin 41 , the staff will open the solenoid valve arranged inside the second drain pipe 42 , thereby discharging the wastewater after secondary treatment into the treatment bin 51 through the second drain pipe 42 .

[0085] During the above process, the flocculent impurities generated by the reaction of the wastewater in the sedimentation bin 41 with the flocculant will fall along the arc surface of the ladder block 45 onto the sludge collection tray 44 arranged at the bottom of the ladder block 45, and after the subsequent wastewater treatment is completed, the staff can manually hold the handle extending from the outer surface of the worm gear 46 and cause the worm gear 46 to rotate. At this time, the sludge collection tray 44 fixedly connected to the worm gear 46 will synchronously rotate with the connection point between the worm gear 46 and the sedimentation bin 41 as the fulcrum, and then the sediment on the sludge collection tray 44 can be poured into the interior of the processing bin 51, and then the impurities on the sludge collection tray 44 can be cleaned, thereby quickly cleaning the generated flocculent sediment.

[0086] During the above process, the worm wheel 46 and the worm screw 47 are meshed, and the worm screw 47 rotates under the action of the worm wheel 46. When the worm wheel 46 stops rotating, the worm screw 47 limits the position of the worm wheel 46 and further limits the position of the sludge collection tray 44 due to the self-locking property of the worm wheel 46 and the worm screw 47. The tilt angle of the sludge collection tray 44 during the cleaning process is controlled and its position is fixed, so that the impurities in the sludge collection tray 44 can be cleaned faster.

[0087] Further treatment of wastewater:

[0088] The wastewater entering the treatment chamber 51 will be further treated in the treatment chamber 51. The staff can add anaerobic bacteria and aerobic bacteria in the treatment chamber 51 to further perform microbial degradation treatment on the wastewater, and after the treatment is completed, the wastewater can be discharged from the device through the discharge pipe 52, thereby achieving a multi-stage treatment effect.
