The sampling apparatus that is used for sediment layering situation in observation, the measurement cesspool
Technical field
The utility model relates to the sampling apparatus that the precipitate situation is observed and lift height is measured in the water body in a kind of water-treatment technology field.
Background technology
In dirty (giving up) water-treatment technology field, comprise liquid object and mud, sand (solid-state) sediment etc. of energy layering in the cesspool.So far, there is no the interface that any device (or instrument) can directly be measured liquid and layering thing in all kinds of cesspools in the sewage treatment area, the thickness of each layer more can't take out the layering liquid sample of each layer.But technical field of sewage is store pond (groove) sampling, measured stratified fluid is again very important, the research work of the favourable support wastewater treatment of detection data that it provides.
Summary of the invention
In order very intuitively to find out the layering situation of sewage intracisternal material, measure the thickness of layering, take out the sample liquid of each layer, the utility model provides a kind of sampling apparatus for sediment layering situation in observation, the measurement cesspool.
The technical scheme that the utility model adopts is:
Be used for the sampling apparatus of sediment layering situation in observation, the measurement cesspool, connected to form successively by sampling short tube 1, non-return valve 2, three-way connector 3, sampling pipe mount pad 4 and the sampling pipe more than one 5; The lower port of described sampling short tube 1 is thief hatch, upper port is being threaded connection the entrance point of non-return valve 2, the endpiece of non-return valve 2 is connected with the first port 31 of web member 3, the second port 32 of web member 3 is connecting an end of sampling pipe mount pad 4, and the other end of sampling pipe mount pad 4 is connecting an end of sampling pipe 5; The other end of sampling pipe 5 is provided with capping 6; Described sampling pipe 5 is comprised of inner and outer tubes, and its inner tube is sample hose 51, and outer tube is protection tube 52.
The two ends of described sample hose 51 and protection tube 52 are equipped with external thread; Connect by internal thread sleeve pipe 61 between adjacent two sample hoses 51, connect by external thread sleeve 62 between adjacent two protection tubes 52.
Described sampling pipe mount pad 4 is straight-tube shape, establishes stepped hole in it, establishes internal thread on the stepped hole hole wall; Large aperture one end matches with the caliber of the outer field protection tube 52 of sampling pipe; Small-bore one end matches with the caliber of the sample hose 51 of sampling pipe internal layer.
Described every protection tube 52 pipe shafts are provided with plural observation window 53.
Be arranged with rubber tube 34 on the 3rd port 33 of described web member 3.
Described sample hose 51 is plexi-glass tubular.
Internal thread is established in described capping 6, is connected with sample hose 51 tops.
The utility model is reasonable in design, use safety, handled easily, intuitively observed the layering situation of sewage intracisternal material, measures lift height, and takes out layering sample liquid for the sewage quality detection, and is very convenient.When device uses, can be as required couple together uses with many group sampling pipes, the fractionation sampling pipe is placed separately when leaving unused.The sample hose of organic glass is provided with protection tube outward, has strengthened the bulk strength of device, damages when avoiding using.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
A kind of for observation, measure the sampling apparatus of sediment layering situation in the cesspool, connect to form successively (Fig. 1) by sampling short tube 1, non-return valve 2, three-way connector 3, sampling pipe mount pad 4 and two sampling pipe 5; The lower port of sampling short tube 1 is thief hatch, upper port is being threaded connection the entrance point (Fig. 3) of non-return valve 2, the endpiece of non-return valve 2 is connected with the first port 31 of web member 3, the second port 32 of web member 3 is connecting an end of sampling pipe mount pad 4, and the other end of sampling pipe mount pad 4 is connecting an end of sampling pipe 5; The other end of sampling pipe 5 is provided with capping 6; Be arranged with rubber tube 34(Fig. 4 on the 3rd port 33 of web member 3).Sampling pipe 5 is comprised of inner and outer tubes, and its inner tube is sample hose 51, and outer tube is protection tube 52.
Sample hose 51 is equipped with external thread for the two ends of plexi-glass tubular and protection tube 52; Connect by internal thread sleeve pipe 61 between adjacent two sample hoses 51, connect by external thread sleeve 62 between adjacent two protection tubes 52.Every protection tube 52 pipe shafts are provided with three observation window 53(Fig. 2).
Sampling pipe mount pad 4 is straight-tube shape (Fig. 5), establishes stepped hole in it, establishes internal thread on the stepped hole hole wall; Large aperture one end matches with the caliber of the outer field protection tube 52 of sampling pipe; Small-bore one end matches with the caliber of the sample hose 51 of sampling pipe internal layer.
Principle of work is as follows: (not adding a cover capping 6) slowly inserted in the pond to be measured after the assembling of tubulose stratified sampler is complete, liquid in the pond is entered in the sampling pipe 5 by sampling short tube 1, non-return valve 2, web member 3 and sampling pipe mount pad 4 by hydrostatic pressure, harden and to enter smoothly in observation-sampler such as the pond bottom sediment, can the move in the direction of the clock top of stratified sampler is by the loosening thing and promote sediment and enter in the sampling pipe 5 of hardening of sampling short tube 1; Then cover capping 6, slowly take out stratified sampler.Non-return valve 2 is the complete outflows that stop sampling pipe 5 interior samples of retaining valve sampling in a whole set of accessory; Be used for setting-out liquid after sheathed rubber tube 34 is taken a sample on web member the 3rd port 33, clamp rubber tube 34 with clip during sampling, take off clip during setting-out liquid and get final product; The sample hose 51 of organic glass is used for preserving sample, waits layering thing thickness to be measured and stratified sampling.
