Abstract
The utility model discloses a mini-sized needle-cylinder water analysis filter, which comprises a needle cylinder, an upper cover board, a lower cover board, a multi-pore splint and a filter film. The upper cover board, the multi-pore splint and the lower cover board are arranged and installed in turn from top to bottom. The multi-pore splint is arranged in the upper cover board transversely. The filter film is installed and fixed at the surface layer of the multi-pore splint. The lower cover board is arranged in the upper cover board transversely and is at the lower layer of the multi-pore splint. A water inlet and a water outlet are respectively arranged between the upper cover board and the lower cover board and are located on the same vertical axes. The pinhole of the needle cylinder can extend into the water inlet of the upper cover board stably. The utility model has the advantages of small size, low cost, small floor area and convenient use and is more applicable to water analysis sampling.
Description
Technical field
The utility model relates to a kind of filter, especially, relates to a kind of miniature water analysis filter that adopts syringe as power source.
Background technology
At present, the filter on the market has two types of malleation and negative pressure, but all adopts air compressor machine formula vavuum pump to exert pressure or adsorb, and when water analysis is taken a sample, often water consumption is 50～60mL, and electric weight is big, volume big, it is many to take up an area of as if taking with kinetic pump, and required equipment is many.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of microneedle cartridge type water analysis filter, adopts syringe to provide private filter as power source for the water analysis process.
The novel microneedle cartridge type water analysis filter of this use specifically is achieved through the following technical solutions.
A kind of microneedle cartridge type water analysis filter comprises syringe, upper cover plate, lower cover, porous supporting plate and filter membrane, and described upper cover plate, porous supporting plate, lower cover install in the upper and lower order successively, and the porous supporting plate of laterally placing is installed in the described upper cover plate; Described filter membrane is mounted on described porous supporting plate top layer; Described lower cover is horizontally installed in upper cover plate inside, and is positioned at porous supporting plate lower floor; Described upper cover plate and lower cover centre position are respectively equipped with water inlet and delivery port, and water inlet and delivery port are positioned on the same vertical axis; Water inlet on the pin hole of described syringe and the described upper cover plate just in time can surely close and stretch into; All install with the sealing ring sealing junction between described upper cover plate, porous supporting plate and the lower cover.
Not only volume is little, cost is low for microneedle cartridge type water analysis filter of the present utility model, and do not take up an area of, easy to use, in the water analysis processing procedure, effectively solved required low wash water sampling filtering problem.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Be illustrated in figure 1 as syringe-type water analysis filter of the present utility model, it comprises syringe 1, upper cover plate 3, lower cover 5, porous supporting plate 4 and filter membrane 6, described upper cover plate 5, porous supporting plate 4, lower cover 5 install in the upper and lower order successively, in the described upper cover plate 3 the porous supporting plate of laterally placing 4 are installed; Described filter membrane 6 is installed on described porous supporting plate 4 top layers; Described lower cover 5 is horizontally installed in upper cover plate 3 inside, is positioned at porous supporting plate 4 lower floor positions; Described upper cover plate 3 and lower cover 5 centre positions are respectively equipped with water inlet 7 and delivery port 8, and water inlet 7 and delivery port 8 are positioned on the same vertical axis; The pin hole 9 of described syringe 1 just in time can surely close with the water inlet 7 of described upper cover plate 3 and stretch into; Junction between described upper cover plate 3, porous supporting plate 4 and the lower cover 5 all adopts sealing ring 2 sealings to install.
When the water analysis sampling is handled, syringe 1 takes out water sample, pin hole 9 is aimed at the water inlet 7 that injects upper cover plate 3, pushing syringe 1 syringe is pressed into described upper cover plate 3 inside with water sample, water sample is because gravity and positive pressure, penetrate the impurity that filters in the water sample etc. by filter membrane 6, flow out by the delivery port 8 in bottom lower cover 5 centre positions again through porous supporting plate 4.Described porous supporting plate can effectively reach under the effect that acts on malleation that holds up filter membrane, and sealing ring 2 can effectively stop water sample pressure to make water sample flow out from upper cover plate 3, lower cover 5 and porous supporting plate 4 junctions, prevents to filter problems such as insufficient.
