Description

Technical Field

[0001] This utility model relates to the field of coagulation wastewater treatment technology, specifically a novel coagulation-flotation wastewater treatment equipment. Background Technology

[0002] Coagulation primarily targets fine suspended particles and colloidal particles in wastewater, which are difficult to separate from the water using natural sedimentation. Coagulation technology involves adding coagulants to wastewater to disrupt the stability of colloids, causing fine suspended particles and colloidal particles to aggregate into larger particles, which then settle and separate from the water, thus purifying the wastewater. Coagulation is a commonly used method in wastewater treatment, used to reduce turbidity, color, and COD in wastewater, and to remove various high-molecular-weight organic compounds, certain heavy metals, and radioactive substances.

[0003] Coagulation experiments are crucial for determining the amount of coagulant added, sludge quality, and operating costs during wastewater treatment. Traditional methods mainly employ coagulation sedimentation, which is time-consuming and inconvenient for users. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a new type of coagulation and flotation wastewater treatment equipment, which solves the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel coagulation-flotation wastewater treatment device includes a stirring assembly. Multiple sets of coagulation reaction components are arranged at the lower end of the stirring assembly. A dissolved air water distribution assembly is connected to one side of each set of coagulation reaction components. A dissolved air water production assembly is connected to the side of the dissolved air water distribution assembly away from the coagulation reaction components. An electrical control assembly is connected to the dissolved air water production assembly and is electrically connected to the stirring assembly. The coagulation reaction components are used for wastewater coagulation reaction and purification. The stirring assembly provides the power for uniform mixing of coagulant and wastewater. The dissolved air water production assembly supplies dissolved air water. The dissolved air water distribution assembly distributes the dissolved air water into the coagulation reactor. The electrical control assembly controls the entire device. This control enables automated control of the novel coagulation-flotation wastewater treatment device during operation, improving its intelligence.

[0006] Furthermore, the coagulation reaction assembly includes a beaker container, a dissolved gas water release pipe, a quick-connect fitting, a sampling valve, and a connection port. The beaker container is placed on a flat platform, and the dissolved gas water release pipe is installed inside the bottom of the beaker container and connected to the quick-connect fitting in a circular shape. The quick-connect fitting connects to the connection port. The outlet of the dissolved gas water distribution assembly is connected to the connection port in the coagulation reaction assembly via a pipe. The sampling valve is used for sampling and measuring the experimental water. The sampling valve allows for faster extraction of the experimental water, improving the overall efficiency of the experiment for sampling and measuring the experimental water.

[0007] Furthermore, the stirring assembly mainly includes a fixed plate, a motor, a coupling, and a stirring rod. The motor is mounted and fixed on the fixed plate and connected to the stirring rod in sequence through the coupling. The stirring assembly is installed at the upper end of the beaker container, and the stirring rod is inserted into the interior of the beaker container to stir and mix the wastewater and the reagent inside the beaker container.

[0008] Furthermore, the dissolved air water manufacturing component is used to allow air to dissolve into water to the maximum extent in the shortest time, forming supersaturated water. The dissolved air water distribution component mainly includes a distributor and a regulating valve, wherein the regulating valve is installed at the rear end of the distributor, and the dissolved air water manufacturing component is connected to the inlet end of the distributor through a pipeline network.

[0009] Furthermore, the electrical control components mainly include an electrical control box, a touch screen, a PLC programmable controller, and a main power switch. The PLC programmable controller is electrically connected to the touch screen. This electrical connection allows user operations on the touch screen to be converted into point signals and transmitted to the PLC programmable controller, enhancing the intelligence of the new coagulation flotation wastewater treatment equipment. Beneficial effects

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This invention adds air flotation technology to conventional coagulation experiments, eliminating the need for settling time. The flocs are directly carried to the upper surface of the beaker by dissolved air water, and then samples are taken directly through the sampling port for testing. This avoids the problem of waiting for sedimentation caused by adding coagulant and then allowing it to settle, which is a traditional method. This method greatly saves time for school teaching, small-scale tests in research institutions, and routine testing in sewage treatment plants, especially in dealing with emergency water pollution situations.

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0018] Example

[0019] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4This application will be described in further detail below. A novel coagulation-flotation wastewater treatment device includes a stirring assembly 2. Multiple sets of coagulation reaction components are installed at the lower end of the stirring assembly 2. A dissolved air water distribution assembly 4 is connected to one side of each set of coagulation reaction components. A dissolved air water production assembly 3 is connected to the side of the dissolved air water distribution assembly 4 away from the coagulation reaction components. An electrical control assembly 5 is connected to the dissolved air water production assembly 3 and is electrically connected to the stirring assembly 2. The coagulation reaction components are used for wastewater coagulation reaction purification. The stirring assembly 2 provides the power for uniform mixing of the coagulant and wastewater. The dissolved air water production assembly 3 supplies dissolved air water. The dissolved air water distribution assembly 4 distributes the dissolved air water into the coagulation reactor. The electrical control assembly 5 controls the entire device. The coagulation reaction components include a beaker container 1, a dissolved air water release pipe 7, a quick-connect fitting 19, a sampling valve 8, and a connection port 9. The beaker container 1 is placed on a flat platform 6. The dissolved air water release pipe 7 is installed inside the bottom of the beaker container 1 and connected to the quick-connect fitting 19 in a circular shape. The quick-connect fitting 19 is connected to the connection port 9. The outlet of the distribution component 4 is connected to the connection port 9 in the coagulation reaction component via a pipe. The sampling valve 8 is used for sampling and measuring the experimental water. The stirring component 2 mainly includes a fixed plate 10, a motor 11, a coupling 12, and a stirring rod 13. The motor 11 is mounted and fixed on the fixed plate 10 and connected to the stirring rod 13 in sequence via the coupling 12. The stirring component 2 is installed at the upper end of the beaker container 1, and the stirring rod 13 is inserted into the interior of the beaker container 1 to stir and mix the wastewater and reagents in the beaker container 1. The dissolved air water production component 3 is used to allow air to dissolve into the water to the maximum extent in the shortest time, forming supersaturated water. The dissolved air water distribution component 4 mainly includes a distributor 14 and a regulating valve 15. The regulating valve 15 is installed at the rear end of the distributor 14. The dissolved air water production component 3 is connected to the inlet end of the distributor 14 via a pipeline network. The electrical control component 5 mainly includes an electrical control box, a touch screen 16, a PLC programmable controller 17, and a main power switch 18. The PLC programmable controller 17 is electrically connected to the touch screen 16.

[0020] The working principle of the PLC programmable controller 17 can be divided into four basic steps: input, processing, output, and feedback. First, the PLC programmable controller 17 receives input signals from external devices or users, such as button presses or information detected by sensors. Next, the PLC programmable controller 17 processes the input signals, performs calculations and judgments according to the set algorithms and logic, and then generates corresponding output signals based on the processing results to control the working status and display information of external devices.

[0021] The sampling valve 8 works by adding a bypass to a normal industrial pipeline to extract samples without affecting the pipeline's normal operation. Specifically, the sampling valve contains a piston or valve inside. When sampling is required, the operator can open the valve to allow fluid to pass through, thus allowing the sample to flow into the sampling tube or container. The design of the sampling valve enables it to quickly and accurately acquire samples during system operation, and it is widely used in quality control and monitoring in industrial production processes. Since the sampling valve 8 is a mature existing technology, it is not described in detail in this utility model.

[0022] Since the touch screen 16, PLC programmable controller 17, main power switch 18, regulating valve 15 and shunt 14 are all common models on the market, and it is necessary to explain that the electrical components and control components of the technical solution of this application are all connected to an external controller and are all prior art. The technical solution of this application has not improved them and does not affect the integrity of the technical solution of this application. Furthermore, the parts not involved or not disclosed in detail are the same as or implemented using prior art. Therefore, this utility model does not elaborate on the above-mentioned devices.

[0023] Among them, the electrical control component 5 is mainly used for the overall control of the stirring component 2, the dissolved air water production component 3 and the dissolved air water distribution component 4, so as to realize intelligent monitoring.

[0024] The working principle of this utility model is explained below: This utility model adds air flotation technology to the conventional coagulation experiment. The dissolved air water production component 3 is controlled by the electrical control component 5 to produce dissolved air water. The dissolved air water produced by the dissolved air water production component 3 is distributed into the coagulation reaction component through the dissolved air water distribution component 4. At this time, the stirring component continuously stirs the coagulation reaction component. No settling time is required. The flocculants are directly brought to the upper surface of the beaker by the dissolved air water. Then, samples are directly taken for testing through the sampling port. This avoids the problem of waiting for sedimentation caused by the traditional method of adding coagulant and then settling. This method greatly saves the time of school teaching, small-scale tests in research institutions and routine tests in sewage treatment plants. In particular, it improves the practicality and intelligence of the new coagulation air flotation sewage treatment equipment, especially in the treatment of water pollution emergencies.

[0025] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
