[0027] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example:

[0029] like Figures 1 to 7As shown, a sewage detection pretreatment device includes a base 1, a mixing tank 5 is fixedly provided on the left side of the upper end face of the base 1, a plurality of dosing components 4 are evenly provided on the top of the mixing tank 5, a water storage cylinder 22 is provided inside the mixing tank 5, a liquid outlet pipe 7 is connected to the left side of the annular surface of the water storage cylinder 22, and the left end of the liquid outlet pipe 7 passes through the mixing tank 5 and extends out, and a liquid outlet tap 6 is equipped with the end of the liquid outlet pipe 7, a second filter cartridge 12 is provided at intervals on the right side of the mixing tank 5, a first filter cartridge 3 is provided on the upper side of the second filter cartridge 12, a transparent observation tube 13 is connected to the left side of the annular surface of the second filter cartridge 12, the upper end of the transparent observation tube 13 is connected to a connecting pipe 9, the left end of the connecting pipe 9 extends into the interior of the mixing tank 5 and is located above the water storage cylinder 22, a water adding head 11 is fixedly connected to the upper right side of the annular surface of the first filter cartridge 3, and a filter screen is provided inside the second filter cartridge 12 19. It is used to capture and intercept large particles of impurities in sewage. A driving motor 10 is installed on the top of the first filter cartridge 3. A threaded screw 18 is vertically provided inside the first filter cartridge 3, and the upper end of the threaded screw 18 is fixedly connected to the output end of the driving motor 10. A piston plate 16 is screwed on the threaded screw 18 through a thread. The piston plate 16 is driven up and down by the threaded screw 18 to achieve pressurized filtration of sewage and improve the filtration efficiency of sewage. This design solves the problem that when sewage is tested, sewage often contains a large amount of complex components such as suspended matter, large particles of impurities and pollutants. These components will interfere with the normal operation of the detection equipment and reduce the accuracy of the test results. At the same time, they will accumulate in the detection equipment, causing blockage of the internal pipes of the detection equipment and affecting the normal operation of the detection equipment.

[0030] In this embodiment, the piston plate 16 is covered with a rubber sheath 17. The annular surface of the rubber sheath 17 is tightly connected to the inner wall of the first filter cartridge 3 through friction. The rubber sheath 17 has excellent elasticity and sealing properties, ensuring a tight fit between the piston plate 16 and the inner wall of the first filter cartridge 3. This seal effectively prevents wastewater leakage during treatment and ensures the overall treatment efficiency and effectiveness of the device. The friction between the rubber sheath 17 and the inner wall of the first filter cartridge 3 stabilizes the piston plate 16 during its vertical movement, preventing it from rotating with the threaded screw 18.

[0031] In this embodiment, the first filter cartridge 3 and the second filter cartridge 12 are detachably connected, with the lower end of the first filter cartridge 3 threadedly engaged with the second filter cartridge 12. This threaded connection allows operators to easily disassemble the first filter cartridge 3 and the second filter cartridge 12 without the need for complex tools or procedures. Furthermore, after disassembly, the filter screen 19 in the second filter cartridge 12 can be easily removed for cleaning, removing accumulated dirt and impurities, ensuring effective filtration and ensuring equipment hygiene.

[0032] In this embodiment, the bottom of the second filter cartridge 12 is an upwardly protruding conical structure, which facilitates the guidance of sewage to the surrounding areas of the bottom. The filter screen 19 is detachably connected to the second filter cartridge 12, and the filter screen 19 is set to a conical structure. The conical structure makes it easier for impurities to gather at the bottom of the filter screen 19 during the filtration process, which is convenient for subsequent discharge and cleaning.

[0033] In this embodiment, a first discharge pipe 14 is connected to the right side of the annular surface of the second filter cartridge 12 for discharging sewage from the second filter cartridge 12. A first valve 15 is mounted on the first discharge pipe 14 to control the discharge of sewage, making it easier for operators to adjust and control the discharge.

[0034] In this embodiment, a second discharge pipe 21 is provided at the bottom of the mixing tank 5, and the upper end of the second discharge pipe 21 is connected to the interior of the water storage cylinder 22, which is used to discharge the sewage in the mixing tank 5 or the wastewater when cleaning the mixing tank 5. The second discharge pipe 21 is equipped with a second valve 20, which can control the discharge of wastewater.

[0035] In this embodiment, the dosing assembly 4 includes a connecting plate 41, a syringe 42, a dosing head 43 and an electric push rod 44. The dosing head 43 is embedded in the top of the mixing tank 5, and its lower end extends into the interior of the mixing tank 5 and is located directly above the water storage cylinder 22. The dosing head 43 is detachably connected to the syringe 42, and an electric push rod 44 is provided on the inner side of the syringe 42. A connecting plate 41 is fixed to the output end of the electric push rod 44, and the bottom surface of the outer end of the connecting plate 41 is in contact with the handle of the syringe 42. The syringe 42 is used to load and inject the detection reagent, making the dosing process more accurate and controllable. At the same time, the electric push rod 44 is electrically driven to provide thrust to the syringe 42, thereby controlling the injection speed and amount of the drug, making the dosing process more automated and accurate. The dosing assembly 4 is configured to accurately add the detection reagent to the water storage cylinder 22, realizing an automated and accurate dosing process.

[0036] In this embodiment, a stirring frame 23 is mounted within the water storage cylinder 22. The lower end of the stirring frame 23 is fixedly connected to the output of the stirring motor 8. The stirring frame 23 promotes uniform mixing of the detection reagent and wastewater within the water storage cylinder 22, thereby improving treatment efficiency. The rotation of the stirring frame 23 creates eddy currents and shear forces between the wastewater and the detection reagent within the water storage cylinder 22, thereby promoting mixing and reaction between the wastewater and the detection reagent, thereby enhancing treatment effectiveness.

[0037] The working principle of this sewage detection and pretreatment device: in actual use, sewage is first added to the first filter cartridge 3 through the water filling head 11, and the sewage passes through the flow channel of the first filter cartridge 3 into the second filter cartridge 12, and flows through the filter screen 19. The filter screen 19 captures and intercepts large particles of impurities in the sewage. At the same time, in the first filter cartridge 3, the drive motor 10 is started, driving the threaded screw 18 to rotate. The threaded screw 18 drives the piston plate 16 to move downward, pressurizing and filtering the sewage, accelerating the flow rate of the sewage, and improving the filtration efficiency of the sewage. At the same time, the filtered sewage flows into the transparent observation tube 13 under the pressure of the piston plate 16, and then flows into the mixing tank 5 through the connecting pipe 9 on the transparent observation tube 13. The transparent observation tube 13 makes it convenient for the operator to observe the sewage filtration situation in the second filter cartridge 12, so as to adjust the treatment parameters in time;

[0038] In the mixing tank 5, sewage flows into the water storage cylinder 22 through the connecting pipe 9. At this time, the dosing assembly 4 starts working, and the electric push rod 44 drives the syringe 42 to accurately add the detection reagent to the water storage cylinder 22 through the dosing head 43. Multiple sets of syringes 42 can be used to add different types of detection reagents. At the same time, the stirring motor 8 starts, driving the stirring frame 23 to rotate, promoting uniform mixing of the sewage and detection reagent, and improving treatment efficiency. Then, the liquid outlet tap 6 is opened to sample and test the mixed sewage.

[0039] In summary, the sewage detection pretreatment device effectively removes complex components such as suspended matter, large particle impurities and pollutants in sewage through precise steps such as dosing, mixing, pressurized filtration and discharge, providing clean samples for subsequent sewage detection, ensuring the accuracy of the test results and the normal operation of the detection equipment.

[0040] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
