Technical Field

[0001] This utility model relates to the field of water sample treatment technology, specifically to a pretreatment device for filtering, defoaming, and separating water samples. Background Technology

[0002] Before water samples are tested, they need to undergo defoaming, filtration, and separation. The core functions of this pretreatment process include removing suspended solids, eliminating bubble interference, and efficiently separating target components.

[0003] Currently, water samples are typically filtered, defoamed, and separated in multiple steps. This requires several containers to hold and transport the pre-treated water samples, which can affect the overall efficiency of subsequent water sample testing. In addition, the use of defoaming agents to eliminate foam in water samples can leave residual chemicals in the samples, potentially affecting subsequent test results. Utility Model Content

[0014] 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.

[0015] Please see Figure 1-5 As shown, a pretreatment device for filtering, defoaming, and separating water samples includes a water storage tank 1. A collar 2 is detachably connected to the top of the water storage tank 1, and a collar 3 is detachably connected to the top of the collar 2. Both the water storage tank 1 and the collar 2 have slots 4 at their tops. Retaining rings 5 ​​are fixedly connected to the bottoms of both the collar 2 and the collar 3, engaging with the slots 4. The engagement of the slots 4 and the retaining rings 5 ​​reinforces the stability and sealing of the collar 2 and the collar 3 after installation. A filter plate 6 and a drainage hopper 7 are fixedly connected inside the collar 2. The filter plate 6 is positioned above the drainage hopper 7, which guides the filtered water sample through the drainage hopper 7. More preferably, the staff can lay filter cloth on the filter plate 6 to improve the filtration effect. An air supply mechanism 8 is installed on one side of the water storage tank 1. The air supply mechanism 8 includes an air box 81 set on one side of the water storage tank 1. Vertical plates 84 are fixedly connected to the surfaces of both sides of the air box 81. The surface of one vertical plate 84 is fixedly connected to the surface of the water storage tank 1. An air injection pipe 9 and an air exhaust pipe 10 are fixedly connected through the interior of the two vertical plates 84 respectively. One end of the air injection pipe 9 and the air exhaust pipe 10 are connected to the air box 81. The other end of the air injection pipe 9 passes through the interior of the water storage tank 1. A one-way valve is connected to the surface of the air injection pipe 9 and the air exhaust pipe 10.

[0016] The one-way valve on the surface of the air injection pipe 9 facilitates the input of air from inside the water storage tank 1 into the air box 81. The one-way valve on the surface of the exhaust pipe 10 facilitates the input of air from inside the air box 81 to the outside, reducing the possibility of reverse air flow. A lifting rod 83 slides through the top of the air box 81, and a piston plate 82 is slidably connected to the inner wall of the air box 81. The bottom of the lifting rod 83 is fixedly connected to the top of the piston plate 82. When the operator moves the lifting rod 83, the piston plate 82 can be moved up and down inside the air box 81 to extract air from inside the water storage tank 1 and discharge it through the exhaust pipe 10. The air discharged through the exhaust pipe 10 can be injected into the water sample. When the water sample produces foam due to the injection of air, surface active substances such as grease, protein, or detergent inside the sample are separated out with the foam. The active substances attached to the surface of the foam may interfere with optical detection or clog instrument components.

[0017] A bracket 11 is fixedly connected to the top of the water storage tank 1. The surface of the exhaust pipe 10 contacts the inner wall of the bracket 11, and the bracket 11 supports the exhaust pipe 10. A cleaning mechanism 12 that can skim off foam is installed inside the collar 2 3. The cleaning mechanism 12 includes a collection cylinder 121 fixedly connected to the inner wall of the collar 2 3. Several triangular plates 122 are embedded in the top of the collection cylinder 121. A cleaning plate 123 is hinged between two adjacent triangular plates 122. A pull rope 124 is fixedly connected to one side of the bottom of the inner wall of the cleaning plate 123. A reinforcing ring 125 is fixedly connected to the top of the pull rope 124. Guide ropes 126 that can move with the lifting rod 83 are fixedly connected to both sides of the top of the reinforcing ring 125. The lifting rod 83 A disc 14 is fixedly fitted onto the surface of the water tank 1. A groove 15 is formed on the surface of the disc 14. The surface of the guide rope 126 contacts the inner wall of the groove 15. At this time, the guide rope 126 is connected to the disc 14. When the lifting rod 83 descends, the guide rope 126 is stressed and can pull the reinforcing ring 125 to rise. The pull rope 124 is stressed and can drive the cleaning plate 123 to rotate. When the cleaning plate 123 rotates, it can skim off the foam in the water. Fixing frames 13 are fixedly connected to both sides of the top of the water tank 1. Guide wheels are rotatably connected to both ends of the fixing frames 13. The surface of the guide rope 126 contacts the surface of the guide wheel. The fixing frame 13 and the guide wheel cooperate to support the guide rope 126 so that the guide rope 126 can move better.

[0018] Working principle: The operator first lays the filter cloth inside the filter plate 6, and then assembles the device. Figure 1As shown in the diagram, the staff can then pour the water sample into the second ring 3. The drain hopper 7, in conjunction with the filter cloth, filters out larger impurities in the water sample, preventing them from clogging the water quality testing instrument used later. After filtration, the water flows through the drain hopper 7 into the water storage tank 1. During this process, the staff can repeatedly press and lift the lifting rod 83. When the lifting rod 83 descends, the piston plate 82 descends accordingly, squeezing out the air inside the air box 81. The exhaust pipe 10 discharges the air into the water sample. The injection of air causes some of the active substances in the water sample to adhere to the bubbles. To prevent such active substances from affecting subsequent testing operations, the piston plate 82 is raised so that air inside the water storage tank 1 can be drawn into the air box 81 through the air injection pipe 9. This not only provides air reserves for subsequent air injection into the water sample, but also improves filtration efficiency through negative pressure. When the lifting rod 83 is pressed down, the disc 14 descends accordingly and can be lifted by the pull rope 124 through the guide rope 126 and the reinforcing ring 125. At this time, the cleaning plate 123 is flipped by force and the foam in the water sample is skimmed off. Afterwards, under the action of gravity, the cleaning plate 123 rotates in the opposite direction for subsequent use.
