Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, in particular to a sewage agent quantitative dosing device. Background Art

[0002] The dosing device for sewage treatment is a device used to add chemical agents to sewage. It aims to promote chemical reactions in the sewage treatment process, thereby efficiently removing pollutants and improving water quality. Its main components include chemical storage tanks, metering pumps, agitators, control systems, pipes and valves, as well as safety facilities. In the process of sewage treatment, the dosing equipment is required to first mix the drug powder and water evenly to form a solution, and then transport the evenly mixed solution to the pool that needs to be treated to achieve sewage treatment.

[0003] Chinese patent authorization announcement No. CN11917659B discloses a dosing device for sewage treatment, which relates to the field of sewage treatment and includes: a dosing component, which is composed of a liquid supply mechanism and a discharge mechanism. The dosing component can realize the function of discharging a drug at different positions of the sewage, so that by discharging the drug from the inside of the sewage, the sewage at different heights can be quickly and evenly reacted with the drug to achieve the corresponding treatment effect, and the use height of the discharge mechanism can be freely adjusted and used, so that it can adapt to the dosing treatment of sewage of different depths and types. It solves the problem that the drug of the dosing device for sewage treatment is added at the top of the stirring tank and then mixed with the sewage in the tank by stirring, which causes the deep sewage to be unable to react with the drug in a timely, rapid and uniform manner, resulting in poor sewage treatment effect.

[0004] The above-mentioned prior art solutions have the following deficiencies:

[0005] 1. Existing sewage chemical dosing equipment has many problems in the mixing process. Its stirring direction is often limited to a single dimension, and can only achieve one-way or a few fixed directions of stirring. This single-direction stirring mode makes it difficult for sewage and chemicals to contact and merge in all directions and at a deep level during the mixing process. Compared with multi-directional stirring, it cannot fully break the flow resistance and concentration gradient within the liquid, greatly limiting the improvement of stirring quality. At the same time, during the process of mixing and blending the drug and sewage, the drug is very likely to precipitate, which not only causes drug waste, but also seriously affects the sewage treatment effect and makes it difficult to meet the strict requirements of the sewage treatment process for uniform distribution of drugs.

[0006] 2. Existing sewage dosing equipment lacks an effective monitoring mechanism during dosing tasks, making it difficult for operators to grasp the remaining amount of drugs in real time. Without accurate information on the remaining amount, it is difficult to replenish drugs on time and in the correct amount based on actual consumption, making it difficult to achieve the key function of timely and quantitative replenishment. At the same time, when the stirring component operates at high speed, a large number of bubbles are inevitably generated. These bubbles occupy a certain space in the liquid, changing the physical properties and flow characteristics of the liquid. On the one hand, the bubbles interfere with the force transmission of the stirring component to the liquid, reducing the actual stirring efficiency. On the other hand, the presence of bubbles hinders the effective collision and reaction between the drug and sewage molecules, which has a very negative impact on the quality of subsequent stirring work, resulting in a significant reduction in the effectiveness of the entire sewage treatment process.

[0007] 3. The existing sewage quantification mainly focuses on treating sewage so that it can eventually meet the discharge standards. In the entire treatment process, this type of equipment has obvious deficiencies in the water quality monitoring link, and it is difficult to effectively sample sewage at different depths, resulting in an inability to comprehensively and accurately determine whether sewage at each depth has met the corresponding discharge standards. The key to this problem lies in the large defects in the sampling structure design of the equipment, and the lack of functional components that can flexibly and accurately obtain sewage samples at different depths, which seriously restricts the work of conducting a comprehensive and detailed evaluation of the sewage treatment effect.

[0008] In view of the above situation, in order to overcome the above technical problems, the present invention provides a sewage reagent quantitative dosing device. Summary of the Invention

[0009] The present invention provides a sewage reagent quantitative dosing device, which solves the problem of realizing the anti-sedimentation function during the stirring and fusion process, promotes the better fusion of the medicine and sewage, and thus makes the sewage treatment effect more significant. At the same time, through the sampling structure, it can be detected whether the sewage meets the national emission standards, which promotes the sewage treatment device to treat sewage effectively.

[0010] In order to achieve the above object, the present invention provides the following technical solutions:

[0011] A sewage agent quantitative dosing device comprises a drug quantitative dosing tank, a tank cover is fixed on the top of the drug quantitative dosing tank, and a first motor is fixed on the top of the tank cover, a second stirring rod is connected to the output end of the first motor, and a stirring seat is provided on the outer side of the second stirring rod, an inner stirring blade is fixed on the inner side of the stirring seat, an accommodating chamber is provided inside the drug quantitative dosing tank, and the bottom end of the accommodating chamber is rotatably connected to the first stirring rod, and a third motor is fixed to the bottom end of the first stirring rod, an outer stirring blade is fixed on the outer side of the first stirring rod, and four groups are provided, each group is provided with two, and the first stirring A first bevel gear is fixed to the outside of the rod, and a first rotating shaft and a second rotating shaft are rotatably connected to the inner wall of the accommodating cavity, and a tipping bucket is fixed to the outside of the first rotating shaft and the second rotating shaft, and the first rotating shaft and the second rotating shaft are respectively connected to the third bevel gear and the second bevel gear on the side close to the first stirring rod. The first bevel gear, the second bevel gear and the third bevel gear are meshed with each other, and a support frame is fixed in four directions below the quantitative drug dosing tank, a discharge pipe is fixed below the quantitative drug dosing tank, a control box is fixed at the front end of the quantitative drug dosing tank, and a single-chip microcomputer is fixed above the control box.

[0012] Preferably, a sampling box is movably connected to the interior of the first stirring rod on one side of the stirring seat, and a sampling groove is provided inside the sampling box. Three groups of sampling grooves are provided, a built-in groove is provided on one side of the sampling groove, and a threaded rod is rotatably connected to the interior of the built-in groove. A threaded sleeve is provided on the outer side of the threaded rod, and a sealing door is fixedly connected to one end of the threaded sleeve. A liquid inlet funnel is fixed to the interior of the sampling box below the built-in groove, and the liquid inlet funnel is electrically connected to the built-in groove.

[0013] In the above scheme, based on existing technology, the sampling structure can detect the fusion of drugs and sewage at different depths at any time to see whether they are stirred and fused evenly to meet national emission standards.

[0014] Preferably, the inner stirring blades and the outer stirring blades are cross-distributed and have opposite rotation directions.

[0015] In the above solution, based on the single structure of the existing stirring component, bidirectional stirring technology is used as an innovative optimization solution. It can stir from two different directions at the same time on the basis of the original stirring mode. This unique operation mode greatly enhances the stirring force, allowing the medicine and sewage to blend more fully and quickly. The stirring effect is more significant than the traditional method, and the efficiency is also greatly improved.

[0016] Preferably, a plurality of groups of bubble cones are fixed on the outer surface of the tipping bucket, and the outer shape of the bubble cones is conical.

[0017] In the above solution, based on the existing technology, a large number of bubbles will appear when the stirring component is stirring. These bubbles will affect the subsequent stirring work and make it difficult to proceed smoothly and efficiently. Improvements to this can enhance market competitiveness.

[0018] Preferably, sealing blocks are fixed on the inner sides of the sealing doors, and the sizes of the sealing blocks fit the sampling slots.

[0019] In the above solution, the sealing block can improve the sealing effect of the sealing door, making the sampling results more efficient and accurate.

[0021] Preferably, a slow-flow channel is provided inside the medicine quantitative box below the liquid inlet funnel, and the shape of the channel is wavy.

[0022] In the above scheme, the slow-flow channel can slow down the flow rate of the drug, making the subsequent filtration structure smoother and more high-quality, thereby filtering out impurities in the drug and ensuring the purity of the drug.

[0023] Preferably, the output end of the background transmission module is electrically connected to the input end of the single-chip microcomputer through a wire, and the output end of the single-chip microcomputer is electrically connected to the input end of the second control valve through a wire, the output end of the weighing sensor is electrically connected to the input end of the single-chip microcomputer through a wire, and the output end of the single-chip microcomputer is electrically connected to the input end of the first control valve and the second motor through a wire.

[0024] In the above scheme, due to a series of electrical relationships, it can play the role of quantitative reminder, prompting the device to discharge materials in a quantitative manner for sewage treatment. At the same time, it can also play the role of monitoring drugs and replenish them in time.

[0025] The beneficial effects of the present invention are as follows:

[0026] 1. Compared with the existing sewage drug quantitative dosing equipment, the present invention starts the first motor to drive the second stirring rod and the outer stirring seat to rotate, and at the same time starts the third motor to drive the first stirring rod and the outer stirring blade to rotate. The outer stirring blade and the inner stirring blade have opposite directions, which can fully break the flow resistance and concentration gradient inside the liquid, greatly improve the quality of stirring, and promote the full fusion of medicine and sewage. The third motor drives the first stirring rod to rotate through the meshing connection, and then drives the tipping buckets on both sides to rotate to prevent the precipitation of medicine, which not only causes waste of medicine, but also seriously affects the sewage treatment effect. In the stirring process, bubbles will appear due to the high-speed stirring of the stirring component. These bubbles occupy a certain space in the liquid, changing the physical properties and flow characteristics of the liquid. The bubble cone can be used to defoam, which makes the stirring and fusion work more efficient and smooth.

[0027] 2. The present invention sets a sampling structure, and the treated sewage flows into the interior of the sampling tank. At this time, the liquid inlet funnel is started and under the action of the threaded connection, the sealing door can be driven to move, covering the outside of the sampling box, thereby achieving a sealing effect. Subsequent staff can take it out for testing. Through the sampling structure, a comprehensive and detailed inspection of the treatment effectiveness of different depth levels in the sewage treatment system can be carried out. The structure can accurately obtain water samples at various depths. Through professional testing processes and analysis methods, the content and related indicators of various pollutants in the sewage can be evaluated in detail. After rigorous comparison and judgment, it is determined whether each layer of sewage has successfully met the strict emission indicators stipulated by the state after treatment, thereby ensuring the quality and compliance of sewage treatment.

[0028] 3. The present invention installs a drug quantitative box. With the cooperation of the slow-flow channel and the filter screen, the drug can be filtered efficiently and with high quality to remove impurities therein, thereby ensuring the purity of the drug. At the same time, with the cooperation of the carrier box and the weighing sensor, the drug can be quantitatively administered. With the cooperation of the scale, the staff can observe the status of the drug at any time and make timely replenishment preparations. The quantitative structure can accurately control the amount of drug administered, allowing pollutants in the sewage to fully react with the drug, effectively removing various harmful substances in the sewage, thereby avoiding drug waste caused by excessive administration. This not only saves drug costs, but also reduces the resources consumed by drug production, transportation, and storage. BRIEF DESCRIPTION OF THE DRAWINGS
