[0026] Please see Figure 1-5A water quality testing pretreatment device further includes a combinable filter assembly. The combinable filter assembly includes a placement rack 9, which is disposed between one side of a partition 3 and a baffle 4. The placement rack 9 has multiple sets of grooves 10 inside, and multiple sets of anthracite filter elements 11, quartz sand filter elements 15, gravel filter elements 16, and manganese sand filter elements 17 are sequentially inserted into the grooves 10 from left to right. Plastic-coated iron rings 14 are fixedly connected to the outside of the 7. A concave opening top cover 12 is fixedly connected to the top of the plastic-coated iron rings 14, and an outward opening bottom cover 13 is fixedly connected to the bottom of the plastic-coated iron rings 14. A crossbar 18 is fixedly connected to the top of the placement rack 9. Two sets of circular fixing rails 19 are fixedly connected to the left side of the front end of the back plate 2. Spare cups 20, anthracite filter element 11, quartz sand filter element 15, gravel filter element 16, and manganese filter element 16 are inserted into the interior of the circular fixing rails 19 from top to bottom. The sand filter element 17 protrudes from the baffle 4. The groove 10, quartz sand filter element 15, gravel filter element 16 and manganese sand filter element 17 are arranged at equal intervals. The placement frame 9 is fixedly connected to the front end of the back plate 2 and one side of the partition 3 and baffle 4. The outer diameter of the plastic-coated iron ring 14 is consistent with the inner diameter of the filter cup 8. The plastic-coated iron ring 14 can be pulled up and down along the inside of the filter cup 8. The inner wall of the fixing plate 6 is tightly fitted with the outer wall of the filter cup 8. The bottom of the filter cup 8 protrudes from the fixing plate 6. The inner diameter of the groove 10 is consistent with the outer diameter of the plastic-coated iron ring 14. The plastic-coated iron ring 14 can be pulled back and forth along the inside of the groove 10. The shape and size of the inside of the circular fixing rail 19 are consistent with the shape and size of the outside of the spare cup 20. The spare cup 20 can be pulled up and down along the inside of the circular fixing rail 19. The surface of the concave opening top cover 12 and the convex opening bottom cover 13 is provided with evenly distributed holes. The inner diameter of the holes is smaller than the inner diameter of the material inside the plastic-coated iron ring 14, which facilitates the free combination of internal filter elements.

[0027] Specifically, such as Figure 1 , Figure 3 and Figure 5 As shown, during use, the groove 10, quartz sand filter element 15, gravel filter element 16, and manganese sand filter element 17 are arranged in descending order of volume and placed into the filter cup 8. Different filter materials can be placed according to different testing requirements. The concave opening top cover 12 and the convex opening bottom cover 13 are adapted to each other and fit tightly when placed into the filter cup 8. Insert the filter cup 8 into the fixing plate 6 and pour the water to be tested into the filter cup 8. Because the concave opening top cover 12 is concave downward, the water flows towards the center and does not overflow to the surrounding area. The water flows into the receiving beaker 5 after being filtered by the groove 10, etc., thus completing the pretreatment of the test water. If multiple sets of water quality comparison tests are required, the spare cup 20 can be removed and the above steps can be repeated to filter simultaneously, so that the data of the two samples can be compared. If the filter cup 8 is damaged and needs to be replaced, the spare cup 20 can also be removed for use. The internal filter elements can be freely combined.

[0028] Example 2: A magnet 21 is provided at the top of the crossbar 18. A handle 22 is fixedly connected to the top of the magnet 21. The internal shape and size of the filter cup 8 and the spare cup 20 are consistent with the external shape and size of the magnet 21.

The shape and size of the bottom of the magnet 21 are adapted to the shape and size of the concave opening top cover 12, which makes it convenient to pick up the internal filter element after filtration.

[0029] Specifically, such as Figure 3 and Figure 4 As shown, when using the filter cup 8, after the water filtration is complete, remove the handle 22 and insert the magnet 21 into the filter cup 8. After the magnet 21 contacts the plastic-coated iron ring 14, it will attract the plastic-coated iron ring 14. At this time, lift the magnet 21 upwards, and the groove 10 will be pulled out by the magnet 21. Then remove the groove 10. Repeat the above steps to remove the remaining filter material in the filter cup 8. After filtration, it is convenient to remove the internal filter element.

[0030] Example 3: The bottom of the shelf 9 is provided with a rectangular groove 23, and a storage box 24 is provided inside the rectangular groove 23. A handle 25 is fixedly connected to the front end of the storage box 24. The shape and size of the inside of the rectangular groove 23 are consistent with the shape and size of the inside of the storage box 24. The storage box 24 can be pulled back and forth along the inside of the rectangular groove 23 for easy storage.

[0031] Specifically, such as Figure 1 and Figure 2 As shown, when in use, unused beakers can be placed in the circular fixed compartment 19, and excess filter material can be placed in the storage box 24. After a test is completed, check the missing material in the empty groove 10, pull the handle 25, pull the storage box 24 forward, take the corresponding material from the storage box 24 and fill it into the groove 10. Excess tools and gloves can also be placed in the storage box 24 for convenient storage of tools, filter materials and other items.

[0032] Working Principle: In use, the groove 10, quartz sand filter element 15, gravel filter element 16, and manganese sand filter element 17 are arranged in descending order of volume and placed into the filter cup 8. Different filter materials can be used according to different testing requirements. The concave top cover 12 and the convex bottom cover 13 are shaped to fit together tightly when placed into the filter cup 8. The filter cup 8 is then inserted into the fixing plate 6. The water to be tested is poured into the filter cup 8. Because the concave top cover 12 is recessed downwards, the water flows towards the center and does not overflow. The water, after being filtered through the groove 10, flows into the receiving beaker 5, thus completing the pretreatment of the test water. If multiple sets of water quality comparison tests are needed, the spare cup 20 can be removed, and the above steps can be repeated to filter simultaneously, allowing for comparison of the data from two samples. If the filter cup 8 is damaged... When replacement is needed, the spare cup 20 can also be removed for use. When using, after the water filtration test is completed, take the filter cup 8 upwards, remove the handle 22, insert the magnet 21 into the filter cup 8, and after the magnet 21 contacts the plastic-coated iron ring 14, it will attract the plastic-coated iron ring 14. At this time, lift the magnet 21 upwards, and the groove 10 will be pulled out by the magnet 21. Then remove the groove 10. Repeat the above steps to remove the remaining filter material in the filter cup 8. When using, the idle beaker can be placed in the circular fixing rack 19, and the excess filter material can be placed in the storage box 24. After one test is completed, check the missing material in the empty groove 10, pull the handle 25, pull the storage box 24 forward, take the corresponding material from the storage box 24 and fill it into the groove 10. Excess tools and gloves can also be placed in the storage box 24.
