technical field

The utility model relates to a field water purification device, in particular to a water purification device suitable for field scientific investigation.

Background technique

When conducting scientific investigations in the field, field workers cannot carry a large amount of drinking water due to their high mobility, and can only fetch water locally. Field water sources include ordinary surface water such as rivers, lakes, ponds, swamps, rainwater and groundwater, and most of them are non-drinkable. Water sources and water quality are complex. At present, there are two main ways to treat drinking water for field workers. First, after obtaining the wild water source, the obtained wild water is sterilized by drugs, precipitated, and boiled for consumption. This method is inconvenient to use, has poor sanitation and safety, and is difficult to meet the demand for wild domestic water. Second, use the outdoor water source purification system to purify the obtained outdoor water for consumption, but the general outdoor water source purification system has problems such as large volume, inconvenient use, and high cost. Therefore, during field scientific investigations, it is an issue that must be considered to provide clean and hygienic drinking water for field workers to effectively protect the life and health of scientific expedition members.

The above-mentioned first filter layer is made of quartz sand and activated carbon.

The above-mentioned second filter layer is composed of a low-pressure high-efficiency microfiltration membrane and polyiodine resin.

The above-mentioned third filter layer is composed of low-pressure high-efficiency microfiltration membrane and polyiodine resin.

Advantage of the utility model and the beneficial effect that produce are:

1. The design of this utility model can make water safer and healthier after three times of filtration, solve the problems of water quality in wild water sources such as impurities, different colors, and peculiar smells, realize efficient purification of wild water sources, and make the work of scientific investigations in the field The personnel can drink clean and hygienic water, and the survival and working ability of field workers can be improved.

2. The utility model is small in size, light in weight, low in cost, low in technological requirements, easy to disassemble, clean, and replace, and is convenient for field scientific investigation staff to use, and also provides a reliable guarantee for advanced scientific research.

Detailed ways

Below in conjunction with accompanying drawing embodiment the utility model is further described:

As shown in Figure 1, a water purification device suitable for field scientific investigations includes a water inlet pipe 1, a foot-operated pressure pump 2, a first filter layer 3, a hollow ultrafiltration membrane filter element 4, a second filter layer 5, and a third filter layer. The filter layer 6, the water pipe 7, the first water tank 8, the second water tank 9, the third water tank 10, and the outlet pipe 11 are characterized in that: the top of the first water tank 8 is provided with a foot-operated pressure pump 2; There is a first filter layer 3; the top of the second water tank 9 is provided with a hollow ultrafiltration membrane filter element 4; the second water tank 9 is provided with a second filter layer 5; the third water tank 10 is provided with a third filter layer 6; the water inlet pipe 1 is connected to the first water tank 8; the first water tank 8 is connected to the second water tank 9 through the water pipe 7; the second water tank 9 is connected to the third water tank 10 through the water pipe 7; the third water tank 10 is connected to the outlet pipe 11.
