When the water sample needs to be sealed and stored, the temporary rubber seal can be connected with the sampling device to store the water sample. This set of water sample draw device lightly easily carries and collects and filters the extraction water sample, drainage discharge water sample, seals up in the short time and deposits the water sample as an organic whole, very big save the sample time, improved experiment work efficiency.
Description
Technical Field
A portable water sample drawing device relates to the field of water treatment experiments.
Background
The sewage treatment purification and water sample extraction experiment is an important part in environmental engineering all the time, and the sewage treatment purification can effectively recycle water resources and effectively save water resources. In the process of sewage treatment and purification, the extraction of a water sample for experiment is an essential link. So a portable water sample draw device has brought conveniently for filtering extraction water sample, ration discharge water sample to and the short time internal seal water sample of depositing. The device is portable and easy to carry, the operation method is simple and easy to learn, the sampling time is greatly saved, and the experimental work efficiency is improved.
Disclosure of Invention
1. Objects of the invention
A portable water sample drawing device is designed in a water experiment. This device can effectually filter aquatic suspended solid, rust, red worm, large granule material such as silt through the cotton filter core of PP, through granule active carbon adsorption tiny particle suspended solid, adsorbs the peculiar smell heterochrosis, filters the impurity irrelevant with the experiment. And a certain volume of water sample is discharged through milliliter scale marks and a drainage joint which are arranged on the device. When the water sample cannot be used temporarily, the water sample can be preserved in a short time through the temporary rubber seal.
2. Technical scheme of the invention
In order to achieve the purpose, the invention designs a portable water sample drawing device, which is characterized in that: from taking the device of getting of milliliter scale mark, the device is got to the volume has four different specifications. The filtering joint with the threaded connection comprises a stainless steel filter screen, a PP cotton filter element and granular activated carbon. A drainage connector with a threaded connection. Temporary rubber seals with threaded connections.
From volume of taking milliliter scale mark device, volume specification has 50ml,100ml,150ml,200ml, has corresponding filter joint according to every specification, drainage joint to and interim rubber seal, can select suitable portable water sample according to the experiment needs and draw the device.
The filter joint who contains stainless steel filter screen, the cotton filter core of PP, granule active carbon, when extracting the water sample, the stainless steel filter screen can play the effect of fixed cotton filter core of PP and granule active carbon, the cotton filter core of PP plays and filters the aquatic suspended solid, the rust, the red worm, large granular substance such as silt, granule active carbon plays and adsorbs the tiny particle suspended solid, adsorbs the heterochrosis of peculiar smell effect.
The drainage tube joint with threaded connection can discharge a certain amount of water samples according to milliliter scale marks and the drainage tube joint on the device when the water samples are needed.
Can seal the temporary rubber of depositing the water sample in the short time seal, when temporarily can not use the water sample, can seal the water sample through temporary rubber and carry out the short time internal seal to deposit, inorganic glass in the rubber seals can guarantee the original shape nature of water sample.
The invention has the beneficial effects that: the invention relates to a portable water sample drawing device, which can filter large granular substances such as suspended matters, rust, red worms, silt and the like in water through a PP (polypropylene) cotton filter element when a water sample, particularly river water, pond water and other sewage is drawn, and granular activated carbon plays a role in adsorbing small granular suspended matters and peculiar smell and heterochrosis. When a water sample is needed, a certain amount of water sample can be discharged according to the measuring device of the milliliter scale lines and the drainage joint, the drainage joint is made of hard smooth plastic, the water outlet is in an oblique arc shape, so that a small amount of water sample can be smoothly slid off, and the accuracy of water sampling is ensured. When can't use the water sample in the short time, can seal the water sample through interim rubber seal and keep, be the rubber material around interim rubber seal, can guarantee its leakproofness, the former form nature of water sample can be guaranteed to the middle inorganic glass that adopts. The device is light and easy to carry, the operation method is simple, the water sample extraction, the quantitative water sample discharge and the water sample sealing and storing in a short time are integrated, the time for people to extract the water sample is greatly saved, and the experiment work efficiency is improved.

Detailed description of the preferred embodiments
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1, the water sample extraction includes: (1) a water pumping handle, (2) a rubber plug, (3) a bottom water absorption plate, (4) a filtering joint, and (12) threaded connection. The water sample discharging device comprises: (1) a water pumping handle, (2) a rubber plug, (3) a bottom water absorption plate, (6) a drainage joint, and (12) threaded connection. The temporary water sample sealing device comprises: (1) a water pumping handle, (2) a rubber plug, (3) a bottom water absorption plate, (10) a temporary rubber seal, (11) inorganic glass, and (12) threaded connection.
As shown in figure 1, when the water sampling device is used and a water sample is extracted, the filtering joint (4) is firstly installed on the bottom water absorption plate (3) through the threaded connection (12), then the device is placed in the water sample to be extracted, the PP cotton filter element in the filtering joint (4) is used for filtering suspended matters, iron rust, red worms, silt and other large granular substances in water, the granular activated carbon is used for adsorbing small granular suspended matters and adsorbing peculiar smell and heterochrosis, and the water sampling device can extract the filtered water sample due to the action of atmospheric pressure by upwards pulling the water pumping handle (1).
