Automatic pumping, sample-sending and acquiring suction filter

Abstract

The invention relates to an automatic pumping, sample-sending and acquiring suction filter. The shell of the suction filter is connected with a lower frame through a screw; the lower frame is connected with a base through a screw; a suction filter system comprises a battery, a vacuum air pump, a clamping base, an exhaust pipe, a gasket, a polyethylene liquid collecting bottle, a filtering membrane, a suction filter top cover and a connector; an operation display system comprises a display panel, an operation button, a circuit board and a print system; the shell is printed with a two-dimensional code; communication between a mobile phone of a sampling person and the suction filter is realized through APP software in a smartphone; a printer is controlled to print two-dimensional code label of water sample acquisition time and place information; the two-dimensional code label is stuck on the polyethylene liquid collecting bottle; and thus, artificial falsification is prevented. By adoption of the automatic pumping, sample-sending and acquiring suction filter in the invention, the polyethylene liquid collecting bottle can be directly stored as a sample bottle; a water sample is directly extracted from an original water sample; the step of artificially adding the water sample in the traditional suction filter is avoided; and the automatic pumping, sample-sending and acquiring suction filter is simple to operate, light in weight and convenient to carry.

Description

technical field [0001] The invention relates to an environmental analysis instrument, in particular to a suction filter for automatic water pumping, sample sending and collection. Background technique [0002] Water resource sampling is an important part of environmental protection. It is necessary to collect and detect the content of particles, organic matter and other soluble elements in water for water resource protection. Therefore, the demand for related environmental protection instruments is very urgent, and the suction filter is mainly used for water sampling. In the collection process, the relevant national regulations clearly stipulate that when measuring soluble elements, the collected water samples must be immediately filtered with a 0.450 μm microporous membrane on site and then placed in a polyethylene liquid collection bottle, which puts forward the following requirements for the suction filter: The suction filter should be easy to carry and have an independen...

Problems solved by technology

[0004] The purpose of the present invention is to provide a suction filter for automatic water pumping and sampling collection, which can solve the problems existing in the existing suction filter, and the sampling personnel can communicate with the suction filter with a smart phone, and obtain a second file containing water sample collection time and location information through a printer. Dimensional code label to prevent fraud; the polyethylene liquid collection bottle is directly stored as a sample bottle, which is convenient to disassemble and connect, and saves the step of pouring the filtrate of the liquid collector into the polyethylene liquid collection bottle in the traditional suction filter to prevent water The sample is mixed with impurities; the suction filter uses a vacuum pump to form a negative pressure, and the water sample is directly drawn from the original water sample device through the suction filter top cover, eliminating the manual steps of adding water samples to the traditional suction filter, so the operation is simple; the shell is made of plastic material , the interior is made of aluminum alloy metal frame, light in weight, the outer deck of the sampler, polyethylene liquid collection bottle, connector and suction filter top cover can be disassembled, so it is easy to carry
