At the same time, the filter net is cleaned by the cleaning assembly to prevent the filter net from being blocked, thereby solving the existing problem of being unable to perform primary filtration. The sewage treatment tank has the advantage of primary filtration.

[0004] In actual operation, workers usually add coagulants to the sewage treatment tank to accelerate the precipitation of impurities in sewage, promote the mutual adhesion and aggregation of colloidal particles in the water, and form larger flocs, which are convenient for separation from the water.

The device draws the coagulant in the drug box 6 into the tank body 1 through the metering pump 4, and the metering pump 4 can accurately measure and transport the drug solution, and can be used A plunger type, piston type or hydraulic diaphragm type is used. Before being sent into the box 1, it will pass through the drug guiding mechanism. The drug liquid first passes through the drug guiding main pipe 5 in the drug guiding mechanism, and then is diverted to two drug guiding branch pipes 9. There are also several auxiliary drug guiding pipes 12 evenly distributed on the drug guiding branch pipes 9. The drug liquid is introduced into the box 1 from different positions on the side from the several auxiliary drug guiding pipes 12. At the same time, the temperature sensor 8 is fixed to the back side of the box 1 by screws. The probe of the temperature sensor 8 is inserted into the box 1 to detect the water temperature inside the box 1 in real time. The heating mechanism inside the box 1 can control the internal water temperature to a certain extent.

[0030] Specifically, the two drug guiding branch pipes 9 are fixed at both ends of the main drug guiding pipe 5 and are connected, the auxiliary drug guiding pipes 12 are arranged on the surface of the drug guiding branch pipes 9 at equal intervals in the longitudinal direction, and the main drug guiding pipe 5 and the auxiliary drug guiding pipes 12 are both inserted into the box body 1. The main drug guiding pipe 5 introduces the drug solution from directly above the box body 1, and the two drug guiding branch pipes 9 introduce the drug solution from the side of the box body 1, so that the drug solution can be quantitatively and evenly introduced into multiple positions of the box body 1 during the introduction process, thereby improving the coagulation effect.

[0031] Further, such as Figure 3 A solenoid valve 10 is installed on the drug guiding main pipe 5, and a solenoid valve 2 11 is installed on the drug guiding branch pipe 9. The installation positions of the solenoid valve 10 and the solenoid valve 2 11 are both near the connection between the drug guiding main pipe 5 and the drug guiding branch pipe 9. The opening and closing of the solenoid valve 10 controls the drug liquid to be introduced from the drug guiding main pipe 5 into the box body 1, and the opening and closing of the solenoid valve 2 11 controls the drug liquid to be introduced from the drug guiding main pipe 5 into the drug guiding branch pipe 9, so that in actual use, the selection of the drug guiding main pipe 5 and the drug guiding branch pipe 9 can be adjusted according to needs.

[0032] In this embodiment, the heating mechanism includes a heat-conducting frame 18 and an electric heating tube 19. The heat-conducting frame 18 is fixedly connected to the inner wall of the box body 1. The electric heating tube 19 is installed in a plurality of heating grooves of the heat-conducting frame 18. The heat-conducting frame 18 can adopt a metal heat-conducting frame, such as copper, aluminum, iron, etc., and a metal frame with better anti-corrosion effect can also be adopted to cope with different types of water quality. The electric heating tube 19 is fixedly installed in a plurality of roots inside the heat-conducting frame 18. The distribution design of the electric heating tube 19 does not affect the auxiliary drug guiding tube 12, the drug guiding main tube 5, the connecting shaft 16, etc., and is staggered with the above-mentioned structure. The heat of the electric heating tube 19 is transferred to the water through the heat-conducting frame 18.

[0033] In this embodiment, a control panel 3 is connected to the front end of the box 1. The control panel 3 has a built-in central processing unit and an A / D converter. The temperature sensor 8 is signal-connected to the control panel 3, and the control panel 3 is electrically connected to the electric heating tube 19 in the heating mechanism. During use, the heating temperature is preset through the control panel 3, and the probe of the temperature sensor 8 detects the water temperature inside the box 1 in real time, and transmits the temperature information to the control panel 3 in real time. The A / D converter in the control panel 3 converts the signal into a digital signal. When the temperature is lower than the preset temperature, the control panel 3 will turn on the electric heating tube 19 until it is heated to the preset temperature.

[0034] Furthermore, a water inlet 2 and a water outlet 7 with flanges are respectively provided on the front and rear sides of the box body 1. The water inlet 2 and the water outlet 7 with flanges are convenient for connection with external pipelines, valves, etc. for the transmission of sewage.

[0035] Specifically, Figure 5A driving motor 15 is fixedly installed at the bottom of the box body 1, and the output shaft of the driving motor 15 is connected to the stirring mechanism. The stirring mechanism includes a connecting shaft 16 fixed to the output shaft of the driving motor 15, and a plurality of stirring rings 17 fixed on the outside of the connecting shaft 16. The driving motor 15 is fixed to the bottom of the box body 1 by screws. The driving shaft of the driving motor 15 passes through the box body 1 and the heat-conducting frame 18 to enter the interior and is fixed to the connecting shaft 16. The rotation of the connecting shaft 16 drives a plurality of stirring rings 17 to rotate, so as to mix and stir the internal sewage and coagulant and improve the reaction effect.

[0036] Furthermore, a medicine box 6 is fixedly installed at the lower end of the metering pump 4, and the medicine box 6 is also fixed at the upper end of the box body 1. The medicine port 13 at the upper end of the medicine box 6 is connected to the feed port at the lower end of the metering pump 4, and the lower end of the medicine port 13 is connected to the corrugated hose 14. Three medicine boxes 20 are arranged in the medicine box 6, and the other end of the corrugated hose 14 is inserted into the interior of one of the medicine boxes 20. Because: the selection of coagulant should be based on the properties, concentration and medium conditions of the colloids and fine suspended matter in the wastewater; for example, for high-concentration fine suspended matter, anionic and non-ionic polymer flocculants can be selected; if the suspended matter in the wastewater is mainly in a colloidal state and has a high electrokinetic potential, it should be considered to use inorganic coagulants in combination with organic polymer flocculants. Therefore, in actual use, multiple coagulants are often required for use. The three medicine boxes 20 can be loaded with different coagulants. When replacement is needed, since the bottom of the medicine extraction port 13 is connected to the corrugated hose 14, it is convenient to manually adjust the insertion position of the corrugated hose 14. The corrugated hose 14 can be inserted into the corresponding medicine box 20, and the medicine solution can be transferred to the metering pump 4 through the corrugated hose 14.

[0037] Working principle: When using the utility model, quantitative transmission can be achieved by using the metering pump 4 as the transmission power structure, and the input amount can be accurately controlled. The coagulant is introduced into the box body 1 through the drug guiding mechanism, and the drug guiding main pipe 5 in the drug guiding mechanism introduces the coagulant from the upper end of the box body 1. The drug guiding branch pipe 9 in the drug guiding mechanism introduces the coagulant from both sides of the box body 1. At the same time, a number of auxiliary drug guiding pipes 12 are distributed on the drug guiding branch pipe 9, which can be introduced to different positions on the side to achieve uniform drug administration in multiple positions. Before precipitation, the heating temperature can be set through the control panel 3, and then the internal real-time temperature can be detected by the temperature sensor 8. The electric heating tube 19 can heat the internal water to a preset temperature, so that a better water temperature is achieved to make the microparticles fully react and reduce the influence of the water temperature on the coagulation effect. In addition, a three-component medicine box 20 is arranged in the medicine box 6, and different types of coagulants can be stored in the medicine box 20. Due to different water quality characteristics, multiple coagulants are often required to be used in combination. Therefore, when replacing the coagulant, the corrugated hose 14 can be inserted into the designated medicine box 20, which is easy to operate.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
