Description

Technical Field

[0001] The utility model relates to the technical field of liquid separation devices, in particular to a liquid separation device for environmental protection detection. Background Art

[0002] The liquid separator in environmental testing is a device used to separate different components in a mixed liquid, especially in the field of water environment and sewage treatment. This device is usually used to separate solid and liquid components in water samples, or liquid components at different densities, such as oil-water separation. The liquid separator helps environmental workers to more accurately analyze and detect water quality to ensure the cleanliness of the water environment and comply with relevant environmental standards. When existing environmental workers conduct environmental testing, the samples to be tested may contain interfering substances, which may lead to deviations in the detection of target substances, thereby affecting the accuracy and reliability of the test results. Therefore, we propose a liquid separator for environmental testing to solve the above problems. Utility Model Content

[0003] In order to overcome the problem that when existing environmental workers conduct environmental testing, the samples to be tested may contain interfering substances, which may lead to deviations in the detection of target substances, thereby affecting the accuracy and reliability of the test results.

[0005] Preferably, the sealing round cover is first driven by the snap-in column to be positioned and connected with the liquid separation barrel through the snap-in hole, and then the receiving box is driven by the mounting column to be positioned and connected with the liquid separation barrel through the mounting hole, and then the water sample to be tested is poured into the liquid separation barrel through the liquid inlet tube through the round hole. After the water sample enters the liquid separation barrel, it is first subjected to preliminary solid-liquid separation through a large-pore filter plate, leaving larger substances on the large-pore filter plate, and then the water sample is further subjected to solid-liquid separation through a small-pore filter plate, leaving smaller substances on the small-pore filter plate. During this process, the arc-shaped column provides firm support for the liquid separation barrel. After the separation of the water sample to be tested is completed, the valve is opened, and the water sample flows out of the liquid outlet pipe into the container. Then, through the drive of the driver, the circular slider drives the placement ring sleeve to slide along the second annular groove and connect with the load-bearing base. In this way, in conjunction with the switch of the valve, each group of containers is loaded with water samples, and multiple groups of tests are performed to reduce the error of the test results.

The fixed plate is fixedly connected to the rotating column through the first annular groove. The arc-shaped slider is slidably connected to the rotating column along the first annular groove. A driver is installed inside the arc-shaped slider. The small hole filter plate can further separate the solid and liquid of the water sample and leave smaller substances on the small hole filter plate. When all the water samples are separated and packaged, the arc-shaped slider drives the scraper to slide along the first annular groove and connect with the rotating column through the drive of the driver, thereby cleaning and collecting smaller substances on the small hole filter plate.

After the water sample enters the liquid separation barrel, it is firstly separated from the liquid by a large hole filter plate, and the relatively large solid is separated. Large substances remain on the large-pore filter plate, and then the water sample is further separated into solid and liquid through the small-pore filter plate, leaving the smaller substances on the small-pore filter plate. In this process, the arc-shaped column firmly supports the liquid separation barrel. When the water sample to be tested is separated, the valve is opened, and the water sample flows out of the liquid outlet pipe into the container.

After the large-pore filter plate is cleaned, the arc-shaped slider drives the scraper to slide along the first annular groove and connect with the rotating column through the drive of the driver, thereby cleaning and collecting the smaller substances on the small-pore filter plate. At the same time, the telescopic push rod drives the arc-shaped push plate to slide along the strip groove and connect with the fixed plate through the drive of the telescopic driver, thereby pushing the smaller substances through the rectangular notch and reaching the receiving box. Then the receiving box is disassembled and the smaller substances inside are detected and analyzed, thereby improving the accuracy and reliability of the detection results.

[0025] When working, the sealing round cover 2 is first driven by the clamping column 201 to be positioned and connected with the liquid separation barrel 1 through the clamping hole 102, and then the receiving box 105 is driven by the installation column 106 to be positioned and connected with the liquid separation barrel 1 through the installation hole 108, and then the water sample to be tested is poured into the liquid separation barrel 1 through the liquid inlet pipe 203 through the circular hole 202. When the water sample enters the liquid separation barrel 1, it is firstly separated from the liquid by a large-pore filter plate 104, and the larger substances are retained on the large-pore filter plate 104.
