Description
Technical field
The utility model relates to the technical field of water sample filtration system, is specifically related to the filter for ammonia nitrogen instrument sample analysis, particularly filter interior structure.
Background technology
When detecting the content of ammonia nitrogen in water body, require tested water body no suspended substance lamp impurity.Filter, as providing ammonia nitrogen instrument water sample pretreating containers, is for the necessary device in ammonia nitrogen instrumental analysis, so the work of its normal table serves very important effect.There is following shortcoming in the ammonia nitrogen filter of current use:
1) volume is too large: general all at 500mm × 400 about mm × 400mm, needs the devices such as very many electric, pipeline, auxiliary equipment simultaneously.
2) installation requirement is high: equipment installation requirement pipeline Inlet and outlet water etc. all meets equipment requirement, and the auxiliary equipment such as electrical equipment exist the problems such as installation specification is high equally.
3) easily block: easy incrustation blocking under the environment of water quality inferiority, the situation dirt of unreasonable structure cannot be cleared up, although there are the equipment such as backwash still cannot solve the problems such as blocking.
4) easily overflow: the equipment such as general filter are not water-tight equipments, overflow occur under the abnormal conditions of pipe water more, cause website and rack stained.
5) later stage cost of upkeep: because filter requires high, the cost of manufacture of materials'use is high, causes the later stage to change the equipment costs such as filtering material high.
Summary of the invention
The purpose of this utility model is to provide the filter for ammonia nitrogen instrument sample analysis, and it adopts embedded filter core structure, and it is convenient that filter material is changed, and cost is lower, and filter integral sealing, effectively prevents overflow.
In order to realize this purpose, the technical solution of the utility model is as follows: a kind of filter for ammonia nitrogen instrument sample analysis, comprise filter body, it is different from prior art and is: described filter body top is provided with lamina tecti, longitudinal cartridge groove is provided with in filter body, this cartridge groove forms cylindrical, hollow cavity, at least one filter element body is provided with in cartridge groove, the bottom of filter element body props up cartridge groove bottom land, the top of filter element body props up sealing ring, sealing circle is between filter body and lamina tecti, above-mentioned filter element body is cylindric, and the post heart is hollow form cavity, annular gap is formed between filter element body and the cell wall of cartridge groove, filter body offers water inlet near bottom place, this water inlet and annular gap UNICOM, lamina tecti place offers delivery port, the post cavity body UNICOM in the heart of this delivery port and filter element body, above-mentioned water inlet is connected with at least one peristaltic pump water side.
The utility model discloses a kind of filter for ammonia nitrogen instrument sample analysis, it adopts embedded replaceable filter cartridge construction, effectively can filter the suspended impurity removed in sampling water body, in actual use, solve existing filter and inconvenience, easily blocking, easily overflow, the unfavorable phenomenon of regular maintenance high in cost of production are installed, this filter installation is simultaneously convenient, cleaning process is easy, regular maintenance cost is lower, can provide good water sample environment for ammonia nitrogen instrument sample analysis.

Fig. 3 is lamina tecti structural representation.
Detailed description of the invention
The utility model discloses a kind of filter for ammonia nitrogen instrument sample analysis, it comprises filter body 1, it is different from prior art and is: described filter body 1 top is provided with lamina tecti 2, longitudinal cartridge groove 3 is provided with in filter body 1, this cartridge groove 3 forms cylindrical, hollow cavity, at least one filter element body 4 is provided with in cartridge groove 3, the bottom of filter element body 4 props up cartridge groove 3 bottom land, the top of filter element body 4 props up sealing ring 5, sealing circle 5 is between filter body 1 and lamina tecti 2, filter body 1 and lamina tecti 2 place are equipped with mutually corresponding sealing ring installation position 12, sealing ring 5 is located in upper and lower two sealing ring installation positions 12, above-mentioned filter element body 4 is in cylindric, and the post heart is hollow form cavity 11, annular gap 6 is formed between the cell wall of filter element body 4 and cartridge groove 3, filter body 1 offers water inlet 7 near bottom place, this water inlet 7 and annular gap 6 UNICOM, lamina tecti 2 place offers delivery port 8, the post cavity body UNICOM in the heart of this delivery port 8 and filter element body 4, above-mentioned water inlet 7 is connected with at least one peristaltic pump 9 water side.
In the specific implementation, the power end of described peristaltic pump 9 is connected with control instrument, is connected with dry point 10 for the water inlet end controlling peristaltic pump 9.
In the specific implementation, be screwed between described lamina tecti 2 and filter body 1.
In the specific implementation, described filter element body 4 outer wall is provided with helical form interception groove or ring-type interception groove, and said structure effectively can increase the footprint on filter element body surface, and contributes to the sedimentation of suspended impurity.This filter element body 4 is the cotton material of PP, and the price that this material commercially buys is very cheap, contributes to controlling maintenance cost.
During use, peristaltic pump power supply connects instrument and controls, by the sample introduction of instrument controlling filter; Peristaltic pump water intaking termination pipeline or dry point, filter is taken in water side; Intake under filter upper water-out, install filter core in the cartridge groove of filter bottom, top top cover fastens filter core, sealed by sealing ring, filter core is hollow material, and water sample is interior through filter core by cartridge groove, clear water is from the hollow bulb water outlet at filter core center, and impurity is staying filter core outer wall through filter core.
