Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment in water sample detection experiments, in particular to a reagent bottle component and a separator for separating experimental extracts. Background Art

[0002] When doing water sample detection experiments, it is often encountered that an organic extract that is immiscible with the water sample is used to extract and separate specific substances in the water sample, and then detect it. At present, the commonly used similar separators on the market are mainly catering oil-water separators and industrial oil-water separators. Catering oil-water separators are used to treat sewage in the catering industry; due to environmental protection requirements, petroleum, chemical, mechanical processing and other enterprises generally produce a large amount of oil-containing industrial wastewater in the production process. These oil-containing wastewaters are discharged into rivers, lakes and seas. The sewage generated by ships and machinery must be treated when discharged into rivers, lakes and seas. Industrial oil-water separators are required, such as the Chinese patent document with authorization announcement number CN215798607 U, which discloses a microchannel oil-water separation chip and oil-water separation system, and the Chinese patent document with authorization announcement number CN 113044903 B, which discloses an oil-water separator. These oil-water separators are all large-scale and suitable for the treatment of oily wastewater. In the laboratory, during the separation process of organic extract and water sample, the total amount of water sample is small, and contamination between different samples needs to be prevented, so the existing oil-water separator is not applicable.

[0003] At present, the traditional solution in the laboratory is to extract by oscillation in a separatory funnel, discard the water sample and then recover the organic extract. In this process, the organic extract volatilizes and drips, resulting in a low recovery rate and environmental pollution. The whole process is time-consuming and labor-intensive, and is not conducive to experimental management. Summary of the invention

Detailed implementation manners

[0021] Now, the present utility model will be further described in detail with reference to the accompanying drawings.

[0022] As Figure 1 、 2 、3, 4, 5, 6, 7 show an extraction liquid separator for experiments, which includes a main machine shell 1, a storage rack 2, a water tank 6, and a water pump. A sample table 101 is provided on the front side of the main machine shell 1, and a storage rack is provided on the sample table 101. A water tank 6 is provided inside the main machine shell 1. The water inlet end of the water pump is connected to the water inlet pipe, and the water inlet end of the water inlet pipe is located inside the water tank 6. The water outlet end of the water pump is provided with a water connection pipe 10. Reagent bottles 3 and test tubes 4 are placed on the storage rack 2. The water connection pipe 8 is connected to the reagent bottle 3 through the interface fixer 5. The reagent bottle 3 is connected to the oil outlet pipe 9 through the interface fixer 5. The oil outlet pipe 9 is connected to the test tube 4.

[0023] Specifically, the interface fixer 5 includes a pipe joint 501, a fixing block 502, and a sealing cover 503. A support ring 5021 is provided on the outer periphery of the fixing block 502. There are two first threaded through holes and a second threaded through hole on the fixing block 502. The pipe joint 501 is respectively assembled in the first threaded through hole and the second threaded through hole. A positioning through hole is provided at the top cover of the sealing cover 503. The lower end of the fixing block 502 is located in the bottle interface 301 of the reagent bottle 3, and the upper end of the fixing block 502 is located in the positioning through hole. The support ring 5021 is located between the top cover of the sealing cover and the upper edge of the bottle interface 301. The inner wall of the sealing cover 503 is detachably connected to the bottle interface of the reagent bottle 3 through a threaded structure. The lower surface of the fixing block 5022 is provided with a spherical groove 5022, and the second threaded through hole is located at the bottom of the spherical groove 5022 of the fixing block 502. The pipe joint 501 in the first threaded through hole is fixed with a water inlet pipe 8, and the free end of the water inlet pipe 8 extends deep into the bottom of the reagent bottle 3. The pipe joint 501 in the second threaded through hole is fixed with an oil outlet pipe 9, and the end face of the oil outlet pipe 9 is located inside the corresponding pipe joint 501, so that the organic extractant can flow out of the oil outlet pipe more effectively.

[0024] Specifically, the storage rack 2 is provided with an upper plate 201 and a lower plate 202 connected to each other. A limiting through hole 203 is opened on the upper plate 201, and a limiting groove 204 is provided on the lower plate 202. The limiting through hole 203 and the limiting groove 204 correspond to each other up and down and have the same size. The limiting through holes are provided in various sizes to adapt to different reagent bottles 3 and test tubes 4.

[0025] Specifically, it further includes a pipeline fixer 7. The pipeline fixer 7 includes a support rod 701, a cross plate 702, a vertical plate 703, and a limiting tube 704. The support rod 701 is provided on the main machine shell 1, the cross plate 702 is assembled on the support rod 701, a vertical plate 703 is provided on the side of the cross plate 702 away from the support rod 701, and a limiting tube 704 is provided on the vertical plate 703. The limiting tube 704 is in interference fit with the water inlet pipe 8 and the oil outlet pipe 9 to play a fixing role, or is connected through a rigid joint to play a fixing role. A fixing through hole is opened on the vertical plate 703 for the water inlet pipe 8 or the oil outlet pipe 9 to pass through, which plays a certain fixing role and also plays a role in adjusting the direction.

[0026] Specifically, an equipment box 105 is provided in the main machine shell 1, and a water pump is provided in the equipment box 105. The water pump is electrically connected to the power interface 102 through a power switch 103 and a speed regulator 104. Among them, the water pump uses a diaphragm liquid pump with a model of KLP04 - 320 - 24, and the speed regulator uses a KVP04 speed control board.

[0027] In actual laboratory use, the density of the extractant in the water sample is smaller than that of water, so the extractant will float on the water. The water sample is filled into the reagent bottle 3. After shaking and standing for a certain time, the water connecting pipe 8 is fixed in one of the pipe connectors, and the free end of the water connecting pipe 8 is directly connected to the bottom of the reagent bottle 3. The oil outlet pipe 10 is fixed in the other pipe connector 501, and the end of the oil outlet pipe in the reagent bottle 3 is at the top. As Figure 7 , 8 shown, when pure water slowly enters the reagent bottle 3 from the bottom of the reagent bottle 3, through the continuous injection of pure water, the upper organic extraction liquid is squeezed upward. When it is squeezed to the end of the oil outlet pipe 9, it exits the reagent bottle, separating the organic extractant in the water sample from the water in the water sample. In this way, the sealing cap 503 and the fixing block 502 are separated. When the sealing cap 503 is tightened, it will seal the fixing block 502 and the bottle interface 301 of the reagent bottle 3. When the sealing cap 503 is loosened, the fixing block 502 can be relaxed. Since the fixing block 502 is made of polytetrafluoroethylene and is sealed with the bottle interface 301 by being pressed by the sealing cap 503, when the sealing cap 503 is rotated, the fixing block 502 will disengage from it and will not rotate with it. It is very convenient to remove the reagent bottle 3 without rotating the reagent bottle 3, and the pipeline will not be disrupted. Each group of experiments uses a set of water connecting pipe 8, oil outlet pipe 9, reagent bottle 3 and test tube 4, which can effectively prevent contamination between different samples. When pure water is slowly injected, since the proportion of the organic extractant in the water sample is very small, compared with the organic extractant, a reagent bottle 3 with a large volume is used, and pure water is slowly injected, so there is enough time to squeeze the organic extractant upward. And when the organic extractant is about to reach the top, the water inlet is at the bottom, which has almost no impact on the organic extractant at the top. After many experiments, it is proved that it can effectively avoid stirring the water sample in the reagent bottle 3 and achieve oil-water separation. This device can also be equipped with a speed regulator 104 according to the situation. When the oil is about to be completely separated, the injection speed of water can be slowed down. In this way, the oily substances such as the upper organic extractant in the reagent bottle 3 can be separated by automatically injecting pure water into the sample reagent bottle 3 and squeezing it out. It is simple and fast. The extractant in the water sample is a liquid layer at the top. As it rises, it enters the oil outlet pipe and is squeezed out, and then enters the test tube 4 for collection.
