[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] ReferenceFigure 1 - Figure 2 This utility model provides an embodiment of a multi-channel filtration device for environmental testing, comprising a base plate 1, a diverter cylinder 2 fixedly connected to the top of the base plate 1 via a fixing frame 3, an inlet pipe fixedly connected to the top of the diverter cylinder 2, and a sealing cap provided above the inlet pipe for sealing the upper end of the inlet pipe when not in use. Samples after initial filtration and uniform stirring can be added to the diverter cylinder 2 through the inlet pipe. A wastewater box 4 is provided above the base plate 1, and a limiting frame is fixedly connected above the base plate 1. The size of the limiting frame is adapted to the size of the wastewater box 4, and the bottom of the wastewater box 4 can be used to place... The sample is placed within a limiting frame to ensure stable placement and prevent displacement that could affect the centralized collection of waste liquid. The bottom surface of the diversion cylinder 2 is fixedly connected to several inlet cylinders 5 in a circular array. The interior of the diversion cylinder 2 is interconnected with the interior of each inlet cylinder 5, allowing the sample in the diversion cylinder 2 to be evenly distributed into each inlet cylinder 5. A solenoid valve 6 is fixedly connected to the outside of each inlet cylinder 5, controlling the opening and closing of the bottom of the inlet cylinder 5. The solenoid valve 6 is positioned identically on each inlet cylinder 5, ensuring that the internal space of each inlet cylinder 5 remains the same when the solenoid valve 6 is closed.

[0032] Reference Figure 2 - Figure 4 The adjacent water inlet cylinders 5 are connected by a connecting pipe 7, and the samples in the adjacent water inlet cylinders 5 can be exchanged through the connecting pipe 7, so that the liquid level of the sample in each water inlet cylinder 5 is kept consistent. This can further improve the uniformity of the amount of sample discharged downward in each water inlet cylinder 5 when the solenoid valve 6 is opened. A drain pipe 8 is set below the connecting pipe 7. The connecting pipe 7 is located directly below the drain pipe 8, and the drain pipe 8 is located directly above the sewage box 4. The liquid that has been filtered after entering the drain pipe 8 can be discharged downward into the sewage box 4 for collection. The outer diameter of the water inlet cylinder 5 and the drain pipe 8 is the same.

[0033] A moving unit 9 is provided on the outside of the sewage pipe 8. The moving unit 9 includes a fixed plate 91, which is fixedly connected to the outside of the sewage pipe 8. The fixed plate 91 is used to fix all the sewage pipes 8 so that all the sewage pipes 8 can move synchronously. An electric telescopic rod 92 is fixedly connected to the bottom surface of the fixed plate 91. The bottom end of the electric telescopic rod 92 is fixedly connected to the upper surface of the base plate 1. When the electric telescopic rod 92 is running, it can drive all the sewage pipes 8 to move up and down synchronously through the fixed plate 91. A filter cylinder 10 is inserted into the upper end of the sewage pipe 8. A filter screen 11 is fixedly connected inside the filter cylinder 10. The filter screen 11 can enter the sample in the filter cylinder 10 for filtration. By setting filter screens 11 with different pore sizes, different target objects can be filtered and captured.

[0034] Reference Figure 2 - Figure 3A sealing unit 12 is provided on the outer side of the filter screen 11. The sealing unit 12 includes an edge ring plate 121, which is fixedly connected to the upper outer side of the filter cylinder 10. The outer diameter of the edge ring plate 121 is larger than the outer diameter of the water inlet cylinder 5. When the filter cylinder 10 is inserted into the upper end of the drain pipe 8, the edge ring plate 121 can limit the filter cylinder 10, so that the filter cylinder 10 can be stably placed on the upper end of the drain pipe 8 and will not fall downward. A sealing ring 122 is fixedly connected to the bottom end of the water inlet cylinder 5 and the upper end of the drain pipe 8.

[0035] After inserting the filter cartridge 10 above the drain pipe 8, the electric telescopic rod 92 can be activated to move the drain pipe 8 upward through the fixing plate 91.

[0036] Working principle: After the operator inserts the filter cylinder 10, which is equipped with filter screens 11 of different pore sizes, into the upper end of the drain pipe 8, the electric telescopic rod 92 is activated, which drives all the drain pipes 8 upward through the fixing plate 91. This causes the edge ring plate 121 to fit and be compressed against the sealing rings 122 at the bottom of the inlet cylinder 5 and the upper end of the drain pipe 8. The sealing rings 122 deform and compress to fill the gaps between the edge ring plate 121 and the bottom of the inlet cylinder 5 and the upper end of the drain pipe 8, thus keeping the outside of the filter cylinder 10 sealed and preventing leakage during sample filtration. The filtered sample can then be filtered... The initially filtered and thoroughly stirred sample is added to the diverter 2 through the inlet pipe, allowing the sample to be diverted into each inlet cylinder 5. Samples in adjacent inlet cylinders 5 can be exchanged through the connecting pipe 7, ensuring that the sample volume in each inlet cylinder 5 remains consistent, thereby improving the accuracy of the filtration structure. Once the liquid level in the inlet cylinder 5 is stable, the solenoid valve 6 is opened, allowing the sample to flow downwards through the bottom of the inlet cylinder 5 to the filter cylinder 10 for filtration. The desired target material is filtered out by the filter screen 11, and the generated waste liquid is discharged downwards through the drain pipe 8 into the wastewater box 4 for centralized collection.

[0037] After filtration is completed, the staff can activate the electric telescopic rod 92 to move the drain pipe 8 down, so that the filter cylinder 10 is exposed. Then the staff can directly and quickly disassemble and remove the filter cylinder 10 through the edge ring plate 121 for easy subsequent testing. The structure is simple and the operation is convenient.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
