Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a device for uniformly dispensing wastewater treatment agents. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. It is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, healthcare, and catering, and is increasingly becoming a part of everyday life. During wastewater treatment, chemical dosing devices are often used for auxiliary treatment. To prevent wastewater from impacting the environment, the Ca ions produced when quicklime dissolves in water can react with sulfate and phosphate ions in the water to form precipitates, reducing the acidity of the water and thus purifying it. In wastewater treatment operations, a portion of quicklime is typically added to the wastewater ditch to treat the wastewater. However, current quicklime addition is mainly done manually, which is not only time-consuming and labor-intensive but also prone to uneven distribution, leading to resource waste.

[0003] Chinese patent CN116514249B discloses a wastewater treatment agent dispensing machine, including a wastewater tank. A planar moving platform is connected to an ash-spreading component via a lifting mechanism. The planar moving mechanism can drive the planar moving platform to move in a horizontal plane, and the lifting mechanism can drive the ash-spreading component to move vertically. The ash-spreading component includes a base plate, an ash-spreading cylinder rotatably mounted on the base plate, a rotary drive device for driving the ash-spreading cylinder to rotate, and a spraying component communicating with the inner cavity of the ash-spreading cylinder. Several through holes are opened on the outer wall of the ash-spreading cylinder, and several spreading blades are evenly connected to the outer side of the ash-spreading cylinder. A main channel and several branch channels are opened on the inner side of the spreading blades. The main channel communicates with the inner cavity of the ash-spreading cylinder through the through holes. One end of the branch channel communicates with the main channel, and the other end of the branch channel extends to the side edge of the spreading blade.

Implementation

[0028] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides: A wastewater treatment agent uniform dispensing device includes a self-propelled frame 1 movable on top of a wastewater treatment tank, a storage tank 2, a diffusion mechanism 3, and a feeding mechanism 4. The storage tank 2 is mounted on the self-propelled frame 1 and extends along the width of the wastewater treatment tank. The diffusion mechanism 3 is evenly spaced at the bottom of the storage tank 2 along the width of the wastewater treatment tank. The diffusion mechanism 3 has a receiving cavity communicating with the storage tank 2 and longitudinally arranged diffusion holes that can diffuse the powdered agent in the receiving cavity laterally into the wastewater. The feeding mechanism 4 is disposed in the storage tank 2 and has a feeding working part extending into the receiving cavity. In operation, the feeding working part feeds the powdered agent in the storage tank 2 into the receiving cavity.

[0030] Wastewater treatment is a critical environmental protection task, but traditional wastewater treatment systems face several challenges, such as cumbersome operation, uneven chemical dosing, and difficulty in real-time monitoring. Therefore, to improve the efficiency and reliability of wastewater treatment systems, increasing research and development efforts are focused on developing innovative technologies and equipment.

[0031] In the context of digital and intelligent online operation and maintenance, automated dosing has become a key component of wastewater treatment systems. This device integrates sensor, automated control, and data analysis technologies to achieve precise dosing and real-time monitoring during the wastewater treatment process.

[0032] First, the automated dosing system employs advanced sensor technology to monitor key parameters in the wastewater treatment system in real time, such as water quality, pH level, and dissolved oxygen. These sensors can exchange data with the system's control system in real time, thereby ensuring the accuracy and timeliness of dosing.

[0033] Secondly, the automated dosing system is equipped with an intelligent control system that can automatically adjust the dosage and frequency of dosing based on data from sensor feedback. This automated dosing process can effectively control the chemical reactions in wastewater treatment and reduce the workload and errors of operators.

[0034] Furthermore, automated dosing can optimize wastewater treatment systems and provide early warnings of potential malfunctions through data analytics. By analyzing large amounts of real-time data, the system can identify potential problems and anomalies and take timely action. This predictive maintenance approach improves the reliability and operational efficiency of wastewater treatment systems.

[0035] In summary, the intelligent online operation and maintenance wastewater treatment system, through the integration of sensors, automated control, and data analysis technologies, achieves precise dosing and real-time monitoring during the wastewater treatment process. This not only improves the efficiency and reliability of the wastewater treatment system but also reduces operating costs and the risk of human error, making a significant contribution to environmental protection.

[0036] In this embodiment, the agent in the storage tank 2 is fed into the diffusion mechanism 3 through the feeding mechanism 4. The diffusion mechanism 3 is evenly distributed with diffusion holes, so that when the diffusion mechanism 3 moves in the wastewater, the agent in the diffusion mechanism 3 can continuously pass through the diffusion holes and dissolve in the wastewater.

[0037] In this embodiment, the storage tank 2 is installed on the self-propelled frame 1, allowing the storage tank 2 to move above the wastewater treatment tank. At the same time, the diffusion mechanism 3 installed at the bottom of the storage tank 2 can be inserted into the wastewater. Simultaneously, the feeding mechanism 4 is activated, allowing the feeding working part of the feeding mechanism 4 to deliver the agent from the storage tank 2 into the diffusion mechanism 3. As the self-propelled frame 1 moves, the agent in the diffusion mechanism 3 passes through the diffusion holes and dissolves in the wastewater. This allows the agent to be quickly dissolved in the wastewater treatment tank, and the agent can be evenly dissolved in wastewater at different depths.

[0038] like Figure 3 As shown, the treatment system also includes a flow disturbance mechanism 5, which is disposed outside the diffusion mechanism 3. The flow disturbance mechanism 5 is connected to the feeding unit in a transmission manner. When the feeding unit is working, the flow disturbance mechanism 5 disturbs the sewage outside the diffusion mechanism 3.

[0039] By installing the flow bypass mechanism on the outside of the diffusion mechanism 3, the wastewater flow velocity outside the diffusion mechanism 3 can be increased, thereby improving the dissolution efficiency of the reagent and wastewater in the diffusion mechanism 3 and increasing the dissolution rate of the reagent.

[0040] like Figure 3 As shown, the diffusion mechanism 3 includes a cylindrical component 31 with its bottom end closed. The cylindrical component 31 is evenly spaced at the bottom end of the storage tank 2 along the width direction of the wastewater treatment tank. The cylindrical component 31 extends longitudinally, and its inner cavity forms a receiving cavity that communicates with the storage tank 2 at its top end. A rectangular array of diffusion holes is arranged on the cylindrical component 31, and the feeding working part of the feeding mechanism 4 extends into the cylindrical component 31.

[0041] The cylindrical component 31 is arranged longitudinally at the bottom of the storage tank 2 so that the cylindrical component 31 can be inserted into the wastewater. At the same time, the inside of the cylindrical component 31 forms a receiving cavity that communicates with the storage tank 2, so that the feeding mechanism 4 can repeatedly feed the agent in the storage tank 2 into the receiving cavity, thereby ensuring that the agent can be uniformly dissolved in the wastewater.

[0042] like Figure 4 , Figure 7 and Figure 8 As shown, the diffusion mechanism 3 further includes an angle adjustment component 32, which is disposed at the bottom end of the storage bin 2. The angle adjustment component 32 includes a first fixed end and a first movable end that can rotate relative to the first fixed end by an angle, with the rotation axis extending longitudinally. The cylindrical component 31 includes an outer cylinder 311 and an inner cylinder 312, both of which have closed bottom ends. The outer cylinder 311 is coaxially disposed at the first fixed end of the angle adjustment component 32, and the outer cylinder 311 has a rectangular array on its circumferential surface. The inner cylinder 312 is coaxially disposed at the first movable end of the angle adjustment assembly 32. The inner cylinder 312 has a rectangular array of second diffuser ports 3121 on its circumferential surface. The inner cylinder 312 is located inside the outer cylinder 311. The outer circumferential surface of the inner cylinder 312 and the inner circumferential surface of the outer cylinder 311 are fitted with a clearance. The intersection of the first diffuser port 3111 and the second diffuser port 3121 forms a diffuser hole. The diameter of the diffuser hole is adjusted by adjusting the rotation angle of the first movable end relative to the first fixed end.

[0043] To adjust the speed at which the medicine in the receiving cavity passes through the diffusion hole, the aperture of the diffusion hole can be adjusted by the angle adjustment component 32. That is, the outer cylinder 311 is fixedly set at the first fixed end of the angle adjustment component 32, and the inner cylinder 312 is installed at the first movable end of the angle adjustment component 32. By adjusting the angle of the first movable end relative to the first fixed end, the intersection area of ​​the first diffusion port 3111 on the outer cylinder 311 and the second diffusion port 3121 on the inner hole can be adjusted, thereby adjusting the aperture of the diffusion hole.

[0044] like Figure 4 , Figure 7 and Figure 8As shown, the bottom of the storage bin 2 is provided with feeding hoppers 21 arranged at equal intervals along its length. The narrow opening at the bottom of the feeding hopper 21 extends downward to form a first flange ring 211. The top of the outer cylinder 311 is provided with a second flange ring 3112, and the top of the inner cylinder 312 is provided with a third flange ring 3122. The third flange ring 3122 is provided with a first arc-shaped groove 3123 coaxial with it. The angle adjustment assembly 32 includes an internal gear ring 321, a fixing pin 322, an external gear ring 323, and a first disc spring 324. The internal gear ring 321 is coaxially and fixedly disposed at the bottom of the first flange ring 211, and the second flange ring 3112 is coaxially and fixedly disposed at the bottom of the first flange ring 211. At the bottom end; the fixing pin 322 is longitudinally fixedly connected to the first flange ring 211, the internal gear ring 321, and the second flange ring 3112; the external gear ring 323 is coaxially and slidably disposed in the internal gear ring 321, and the external gear ring 323 can mesh with the internal gear ring 321; the third flange ring 3122 is coaxially and slidably disposed between the first flange ring 211 and the internal gear ring 321; the fixing pin 322 passes through the first arc-shaped groove 3123; the top end of the outer circumferential surface of the inner cylinder 312 is coaxially and interference-fitted with the inner circumferential surface of the external gear ring 323; the first disc spring 324 is sleeved on the fixing pin 322, and the first disc spring 324 is located between the third flange ring 3122 and the first flange ring 211.

[0045] By setting the feed hopper 21 at the bottom of the storage tank 2, the agent in the storage tank 2 can be evenly distributed in the feed hopper 21. When it is necessary to adjust the diameter of the diffuser hole, the third flange ring 3122 is lifted upward, so that the outer gear ring 323 and the inner cylinder 312 move upward, so that the outer gear ring 323 and the inner gear ring 321 disengage, and the inner cylinder 312 can rotate a certain angle in the outer cylinder 311. In this way, after adjusting the intersection area of ​​the first diffuser port 3111 and the second diffuser port 3121, the third flange ring 3122 is released. Under the action of the first disc spring 324, the third flange ring 3122 drives the outer gear ring 323 to slide back into the inner gear ring 321, thereby fixing the inner cylinder 312 and the outer cylinder 311 and preventing the inner cylinder 312 and the outer cylinder 311 from rotating relative to each other.

[0046] like Figure 4 As shown, the angle adjustment component 32 also includes a closed cylinder 325. The top end of the inner circumferential surface of the inner cylinder 312 is provided with a stepped groove. The closed cylinder 325 is coaxially inserted into the stepped groove. The top end of the closed cylinder 325 extends to the lower opening of the feed hopper 21. The outer circumferential surface of the closed cylinder 325 is coaxially and clearance-fitted with the lower opening of the feed hopper 21.

[0047] By placing the closed cylinder 325 at the top of the inner cylinder 312, the agent at the bottom of the feed hopper 21 is prevented from overflowing outward through the gap between the third flange ring 3122 and the first flange ring 211.

[0048] like Figure 4 As shown, a first grip 3124 extending radially is provided on the outer circumferential surface of the third flange ring 3122.

[0049] The first handle 3124 facilitates the upward lifting of the third flange ring 3122, making it easy to adjust the diameter of the diffuser hole.

[0050] like Figure 5 As shown, the feeding mechanism 4 includes a drive shaft 41, a stirring shaft 42, a driven shaft 43, a closed box 44, a first bevel gear 45, a second bevel gear 46, and a motor 47. The drive shaft 41 is rotatably arranged in the storage box 2. The stirring shaft 42 is radially distributed on the circumferential surface of the drive shaft 41. The driven shaft 43 is longitudinally arranged in the storage box 2, with its lower end extending to the bottom end of the cylindrical assembly 31. A helical blade 431, coaxial with the driven shaft 43, is arranged on its circumferential surface. The outer edge of the spiral blade 431 is clearance-fitted with the inner wall of the cylindrical assembly 31, and the bottom end of the driven shaft 43 slides through the closed bottom end of the inner cylinder 312; the closed box 44 is disposed at the intersection of the driving shaft 41 and the driven shaft 43; the first bevel gear 45 is coaxially disposed on the driving shaft 41, and the second bevel gear 46 is coaxially disposed at the top end of the driven shaft 43. The first bevel gear 45 and the second bevel gear 46 are both located in the closed box 44, and the first bevel gear 45 and the second bevel gear 46 mesh with each other; The motor 47 is located on the outside of the storage box 2, and the output shaft of the motor 47 is coaxially and fixedly connected to the drive shaft 41.

[0051] When the motor 47 is started, the drive shaft 41 drives the stirring shaft 42 to rotate, so that the medicine in the storage tank 2 can be dispersed and avoid clumping. At the same time, the first bevel gear 45 and the second bevel gear 46 drive the driven shaft 43 to rotate, so that the spiral blades 431 on the driven shaft 43 rotate, thereby feeding the material in the storage tank 2 into the cylindrical component 31.

[0052] Meanwhile, the first bevel gear 45 and the second bevel gear 46 are located in the enclosed box 44, which can prevent the agent from damaging the first bevel gear 45 and the second bevel gear 46 and affecting the transmission.

[0053] like Figure 6 , Figure 9 and Figure 10As shown, the aerodynamic mechanism 5 includes a deflection adjustment component 51, a spoiler 52, and a positioning ring 53. The deflection adjustment component 51 is coaxially rotatably disposed at the bottom end of the cylindrical component 31. The bottom end of the driven shaft 43 is connected to the deflection adjustment component 51. The deflection adjustment component 51 has a second fixed end and a second movable end that can deflect around the second fixed end. The spoiler 52 is distributed circumferentially on the outside of the cylindrical component 31. One side of the bottom end of the spoiler 52 is connected to the second fixed end, and the other side of the bottom end of the spoiler 52 is connected to the second piston end. The positioning ring 53 is coaxially disposed at the top end of the spoiler 52 with the cylindrical component 31.

[0054] When the driven shaft 43 rotates, the deflection adjustment component 51 rotates at the bottom of the cylindrical component 31, thereby driving the baffle 52 installed on the deflection adjustment component 51 to rotate. At the same time, the positioning ring 53 installed at the top of the baffle 52 can ensure the stable rotation of the baffle 52. The rotation of the baffle 52 can accelerate the flow rate of wastewater outside the cylindrical component 31, thereby accelerating the dissolution of the agent in the wastewater.

[0055] like Figure 6 , Figure 9 and Figure 10 As shown, the deflection adjustment assembly 51 includes a fixed disk 511, an adjustment disk 512, a fixed ring 513, and a second disc spring 514. The fixed disk 511 is coaxially disposed at the bottom end of the cylindrical assembly 31. The bottom end of the driven shaft 43 passes through the fixed disk 511 and is fixedly connected to it. The fixed disk 511 is provided with a second arc-shaped groove 5111 distributed along its circumference. The bottom end of the spoiler 52 is provided with a fixed post 521 and a movable post 522 on both sides respectively. The fixed post 521 is rotatably disposed on the fixed disk 511, and the movable post 522 passes through the second arc-shaped groove 5111. The bottom end of the fixed disk 511 is provided with a second arc-shaped groove 5111 distributed along its circumference. The device comprises a circumferentially distributed toothed block 5112; an adjusting disk 512 is coaxially rotatably disposed at the bottom end of the fixed disk 511, and the bottom end of the driven shaft 43 slides through the adjusting disk 512; the top end of the adjusting disk 512 is provided with a toothed groove 5122 distributed along its circumference, and when the adjusting disk 512 abuts against the fixed disk 511, the toothed groove 5122 and the toothed block 5112 mesh, and the bottom end of the movable column 522 slides through the adjusting disk 522; a fixed ring 513 is coaxially disposed at the top end of the driven shaft 43; and a second disc spring 514 is sleeved on the driven shaft 43, and the second disc spring 514 is located between the adjusting disk 512 and the fixed ring 513.

[0056] With the driven shaft 43 output torque fixed, when it is necessary to adjust the rotation of the baffle 52, the adjusting disk 512 moves downward relative to the fixed disk 511, so that the tooth block 5112 disengages from the tooth groove 5122. The adjusting disk 512 can rotate at the bottom of the fixed disk 511, so that the piston column at the bottom of the baffle 52 deflects relative to the fixed column 521. This allows the rotation angle of the baffle 52 outside the cylindrical assembly 31 to be adjusted, thereby adjusting the wastewater flow rate outside the cylindrical assembly 31 with the driven shaft 43 at a fixed torque.

[0057] The adjustment disc 512 is provided with second handles 5121 on both sides, which makes it easier to press down the adjustment disc 512 relative to the fixed disc 511.

[0058] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
