Abstract
Description
Technical Field
[0001] This invention relates to the field of wastewater treatment technology, specifically to an intelligent dosing device for wastewater treatment. Background Technology
[0002] In the wastewater treatment process, processes such as coagulation and flocculation, pH neutralization, nitrogen and phosphorus removal, and water disinfection all require the addition of chemical dosing devices to quantitatively add PAC, PAM, acid and alkali solutions, phosphorus removal agents, and other chemicals. The accuracy of chemical dosing, the homogeneity and stability of the chemical solution, and the uniformity of the mixing between the chemical and the wastewater directly determine the stability of the effluent quality and the cost of chemical consumption. These are the core supporting equipment of the wastewater treatment plant.
[0003] However, in existing wastewater treatment dosing processes, chemicals are usually added at the top of the wastewater reaction tank. But because a large amount of sludge and foam often accumulates on the surface of the wastewater tank, this sludge and foam will coat the chemicals added at the top, hindering the diffusion of the chemicals. Under large water volume conditions, the mixing of surface water and chemicals is limited, resulting in low effective utilization of chemicals. At the same time, the chemicals in the dosing tank will have the problem of sedimentation and stratification after long-term use, causing a large difference in the concentration of chemicals in the tank. As a result, the actual dosage cannot meet the process requirements, the effluent quality fluctuates significantly, and the consumption of chemicals increases dramatically.
[0004] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention comprises a drive shaft, a rotating shaft, a guide groove, stirring blades, a sleeve, a pull rod, a guide groove, and a guide rod. A drive motor drives the drive shaft to rotate continuously. This continuous rotation causes sliding rods on both sides of the rotating shaft to slide within a wave-shaped, interconnected guide groove. This allows the rotating shaft to move rhythmically up and down while rotating. Combined with the elastic restoring effect of a first spring, the stirring blades automatically switch postures during their up-and-down movement, guided by a spiral structure. During downward movement, the blades gradually turn to a vertical position, penetrating deep into the bottom layer of sewage to agitate the high-concentration chemicals. During upward movement, the blades gradually turn to a horizontal position, stirring the upper water layer. This fully elevates and diffuses the high-concentration chemicals from the bottom sewage, achieving thorough mixing without dead zones and preventing the upper-layer chemicals from being affected by floating sludge and foam.
[0016] 2. This invention comprises a drug delivery pipe, a contact plate, a support rod, a push plate, a disturbance plate, a contact block, a push rod, and a push block. A screw module drives the moving plate to move laterally. Combined with the arc-shaped push block and the push rod and spring reset structure, the disturbance plate reciprocates up and down. Simultaneously, the inclined contact block enables the disturbance plate to slide radially, creating a combined disturbance effect of surging up and down and radial diffusion. Compared to traditional fixed static drug storage structures, this structure continuously disperses and mixes the drug that has settled and clumped at the bottom of the storage tank, effectively solving the problem of stratified sedimentation within the tank and ensuring a uniform and stable output drug concentration throughout the process. Simultaneously, a wastewater concentration sensor provides real-time feedback on water quality concentration, allowing the controller to adaptively adjust the drug dosage of the delivery pump, effectively avoiding excessive drug waste or insufficient flocculation due to insufficient dosage. This significantly reduces drug consumption and maintenance costs, demonstrating a high degree of intelligence. Attached Figure Description

[0019] 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.
[0020] Please see Figures 1-8 The present invention provides a technical solution: an intelligent dosing device based on sewage treatment, including a sewage treatment tank 1, a screw drive module installed on both sides of the top of the sewage treatment tank 1, a movable plate 2 installed on the top of the screw drive module, a storage tank 3 fixedly connected to the middle area of the top of the movable plate 2, a accommodating shell 4 fixedly connected to both sides of the storage tank 3 on the top of the movable plate 2, a cover plate 5 installed on the top of the sewage treatment tank 1, a stirring and homogenizing mechanism installed inside the accommodating shell 4, and an anti-sedimentation mechanism installed inside the storage tank 3; The device as a whole relies on the screw drive module to drive the moving plate 2 to move laterally along the top of the sewage treatment tank 1, so that the storage tank 3 and the container shell 4 on the top of the moving plate 2 move synchronously, and the flocculant in the storage tank 3 is continuously transported to the bottom liquid surface of the sewage treatment tank 1 through the drug delivery pipe 71. The mixing mechanism includes a drive shaft 61 rotatably connected to the inner wall of the top of the container 4. The drive shaft 61 is driven by a drive motor installed on the top of the container 4. A rotating shaft 62 is sleeved on the surface of the drive shaft 61 away from the drive motor and extends into the sewage treatment tank 1. The rotating shaft 62 is vertically limited and slidable on the surface of the drive shaft 61. A guide groove 63 is provided on the inner wall of the container 4. Sliding rods 64 are fixedly connected to both sides of the end of the rotating shaft 62 located inside the container 4. A drive bevel gear 65 is rotatably connected to the inner wall of one end of the rotating shaft 62 inside the sewage treatment tank 1. Driven bevel gears 66 are provided on both sides of the drive bevel gear 65. The output end of the driven bevel gear 66 extends out of the rotating shaft 62 and is fixedly connected to the stirring blade 67. The guide groove 63 is opened along the inner wall of the housing 4 in a wave-like structure with the ends connected. The end of the sliding rod 64 away from the rotating shaft 62 is limited and slides in the guide groove 63. The tooth surfaces of the drive bevel gear 65 and the driven bevel gear 66 mesh with each other. Four sets of drive bevel gears 65 and driven bevel gears 66 are vertically and equidistantly arranged inside the rotating shaft 62. A drive assembly is provided on the top of the drive bevel gear 65. The drive motor continuously drives the drive shaft 61 to rotate, and the drive shaft 61 drives the outer rotating shaft 62 to rotate synchronously. The sliding rods 64 fixed on both sides of the rotating shaft 62 slide within the wave-shaped guide groove 63 that connects the beginning and end. Under the constraint of continuous rotational motion, the rotating shaft 62 can synchronously generate regular up-and-down reciprocating motion, and cooperate with the first spring to achieve elastic reset, ensuring smooth and continuous lifting motion. The up-and-down movement of the rotating shaft 62 drives the stirring blade 67 to move up and down as a whole, and rotate circumferentially.
[0021] In one embodiment of the present invention, the drive assembly includes a sleeve 681 fixedly connected to the top of the drive bevel gear 65, a pull rod 682 fixedly connected to the bottom of the drive shaft 61, a first spring sleeved on the surface of the pull rod 682, one end of the first spring fixedly connected to the bottom of the drive shaft 61, and the other end fixedly connected to the inner wall of the top of the rotating shaft 62, a guide groove 683 is provided on the inner wall of the sleeve 681, the pull rod 682 extends into the sleeve 681 and is fixedly connected to a guide rod 684, the sleeve 681 is provided with four sets corresponding to the drive bevel gear 65, the pull rod 682 vertically passes through the sleeve 681 and the drive bevel gear 65 in sequence, the guide groove 683 is opened in a spiral structure along the wall of the pull rod 682, and four sets of guide rods 684 are provided on the surface of the pull rod 682 corresponding to the position of the guide groove 683 inside the pull rod 682, and the guide rods 684 are limited to slide within the guide groove 683; The pull rod 682 at the bottom of the drive shaft 61 moves relative to the rotating shaft 62 as it moves up and down. The guide rod 684 fixed on the outside of the pull rod 682 slides within the spiral guide groove 683 on the inner wall of the sleeve 681, converting the relative movement of the pull rod 682 into the circumferential reciprocating rotation of the sleeve 681. The reciprocating rotation of the sleeve 681 drives the bottom active bevel gear 65 to continuously reciprocate. The active bevel gear 65 meshes with the driven bevel gears 66 on both sides to reciprocate synchronously. The reciprocating rotation of the driven bevel gears 66 drives the stirring blade 67 to reciprocate. As the stirring blade 67 moves down with the rotating shaft 62, it gradually switches to a vertical state based on the limiting and guiding effect of the spiral guide structure. The blade vertically penetrates into the bottom of the sewage, disturbing the sewage with high concentration of chemicals at the bottom and breaking the stagnant zone of the bottom water. As the stirring blade 67 moves up with the rotating shaft 62, it gradually rotates to a horizontal state, which can continuously lift and fully diffuse the mixed water of high concentration of chemicals and sewage at the bottom.
[0022] In one embodiment of the present invention, the anti-sedimentation mechanism includes a drug delivery pipe 71 fixed to the bottom of the drug storage tank 3. The drug delivery pipe 71 is connected to the drug storage tank 3 and extends to the bottom of the sewage treatment tank 1. An abutment plate 72 is sleeved around the drug delivery pipe 71 above the moving plate 2. Support rods 73 are fixedly connected to both sides of the top of the abutment plate 72. The support rods 73 extend into the inside of the drug storage tank 3 and are fixedly connected to a push plate 74. A disturbance plate 75 is laterally limited and slidable on the top of the push plate 74. An abutment block 76 is fixedly connected to the top of the inside of the drug storage tank 3 corresponding to the disturbance plate 75. The top of the disturbance plate 75 is located on the surface of the abutment block 76. The sliding groove is designed to limit the movement of the slide. The bottom of the contact plate 72 is fixedly connected to the push rod 77. The top of the cover plate 5 is fixedly connected to the push rod 77. The top of the drug delivery pipe 71 is equipped with a delivery pump 8. The outer surface of the drug delivery pipe 71 located inside the sewage treatment tank 1 is equipped with a sludge concentration sensor 9. The sludge concentration sensor 9 is connected to the delivery pump 8 through an electrical signal. A controller 10 is installed on one side of the outer periphery of the sewage treatment tank 1. The bottom end of the push rod 77 passes through the moving plate 2 and is rotatably connected to a roller. Several sets of push blocks 78 are set on the surface of the cover plate 5. The positive cross section of the several sets of push blocks 78 is set as an arc structure. The support rod 73 is fitted with a second spring, the middle area of the push plate 74 has a circular notch, the disturbance plate 75 is evenly arranged in four groups around the surface of the push plate 74, the abutting block 76 is arranged in four groups corresponding to the position of the disturbance plate 75, the sliding surface of the abutting block 76 is set as an inclined structure, and the surface of the disturbance plate 75 has several groups of through holes. The push rod 77, which is fixedly connected to the bottom of the contact plate 72, moves synchronously with the moving plate 2, causing the push rod 77 and rollers at the bottom of the contact plate 72 to roll along the surface of multiple sets of arc-shaped push blocks 78 on the top of the cover plate 5. The arc-shaped push structure of the push block 78 drives the contact plate 72 to move upward, and then the support rod 73 at the top of the contact plate 72 drives the push plate 74 and the disturbance plate 75 to move upward as a whole. When the push rod 77 leaves the high point of the push block 78, under the elastic reset action of the second spring, the contact plate 72 and its top structure quickly move downward and reset, realizing the continuous up and down reciprocating motion of the disturbance plate 75 in the medicine storage tank 3. At the same time, the disturbance plate 75 is slidably assembled on the surface of the inclined contact block 76, so that the disturbance plate 75 generates radial expansion sliding motion synchronously during the up and down movement.
[0023] Working principle: During use, the device relies on the screw drive module to drive the moving plate 2 to move laterally along the top of the sewage treatment tank 1, so that the storage tank 3 and the container shell 4 on the top of the moving plate 2 move synchronously. The flocculant in the storage tank 3 is continuously transported to the bottom liquid surface of the sewage treatment tank 1 through the delivery pipe 71. During operation, the drive motor continuously drives the drive shaft 61 to rotate, and the drive shaft 61 drives the outer rotating shaft 62 to rotate synchronously. The sliding rods 64 fixed on both sides of the rotating shaft 62 slide within the wave-shaped guide groove 63 connected end to end. Under the constraint of continuous rotational motion, the rotating shaft 62 can synchronously generate regular up and down reciprocating motion, and with the help of the first spring, it can achieve elastic reset, ensuring smooth and continuous lifting motion. The up and down movement of the rotating shaft 62 drives the stirring blade 67 to move up and down as a whole, and rotate circumferentially. Meanwhile, the pull rod 682 at the bottom of the drive shaft 61 moves up and down with the rotating shaft 62, generating relative movement. The guide rod 684 fixed on the outside of the pull rod 682 slides within the spiral guide groove 683 on the inner wall of the sleeve 681, converting the relative movement of the pull rod 682 into the circumferential reciprocating rotation of the sleeve 681. The reciprocating rotation of the sleeve 681 drives the bottom active bevel gear 65 to continuously reciprocate. The active bevel gear 65 meshes with the driven bevel gears 66 on both sides to reciprocate synchronously. The reciprocating rotation of the driven bevel gears 66 drives the stirring blade 67 to reciprocate. As the stirring blade 67 moves down with the rotating shaft 62, it gradually switches to a vertical state based on the limiting and guiding effect of the spiral guide structure. The blade vertically penetrates into the bottom of the sewage, disturbing the sewage with high concentration of chemicals at the bottom and breaking the stagnant zone of the bottom water. As the stirring blade 67 moves up with the rotating shaft 62, it gradually rotates to a horizontal state, which can continuously lift and fully diffuse the mixed water of high concentration of chemicals and sewage at the bottom, greatly improving the reaction and fusion effect of chemicals and sewage. During the movement of the movable plate 2, the push rod 77 fixedly connected to the bottom of the contact plate 72 moves synchronously with the movable plate 2, causing the push rod 77 and rollers at the bottom of the contact plate 72 to roll along the surface of multiple sets of arc-shaped push blocks 78 on the top of the cover plate 5. The arc-shaped push structure of the push blocks 78 drives the contact plate 72 to move upward, and then the support rod 73 at the top of the contact plate 72 drives the push plate 74 and the disturbance plate 75 to move upward as a whole. When the push rod 77 disengages from the high point of the push block 78, under the elastic reset action of the second spring, the contact plate 72 and its top structure quickly move downward and reset, realizing the continuous up-and-down reciprocating motion of the disturbance plate 75 inside the medicine storage tank 3. At the same time, the disturbance plate 75 is slidably assembled on the surface of the inclined contact block 76, so that the disturbance plate 75 moves up and down during the process. The synchronous radial expansion sliding action, combined with the through-hole on the surface of the disturbance plate 75, creates an up-and-down surging and radial diffusion action inside the storage tank 3 to further disturb the agent in the storage tank 3. This continuously disturbs, lifts, and disperses the agent at the bottom of the storage tank 3, thoroughly breaking up any deposits or clumps of agent at the bottom of the tank, ensuring a uniform concentration of the output agent from the storage tank 3. At the same time, the sludge concentration sensor 9 installed around the delivery pipe 71 collects the sewage pollutant concentration signal in real time and feeds it back to the controller 10. The controller 10 dynamically and adaptively adjusts the operating power and delivery flow of the delivery pump 8 according to the real-time water quality concentration. When the sewage concentration increases, the dosage is automatically increased; when the sewage concentration decreases, the dosage is automatically decreased, precisely matching the real-time sewage treatment conditions and achieving intelligent on-demand dosing.
