Abstract
A kind of novel biochemical oxygen demand sampling bottle, including narrow-mouthed bottle and guiding device, wherein guiding device are fixed on inside narrow-mouthed bottle by narrow-mouthed bottle lid.Guiding device is made up of water conservancy diversion pipe close, water conservancy diversion straight tube, helical form mozzle, horn-like kuppe.Wherein helical form mozzle both ends connection water conservancy diversion straight tube and horn-like kuppe, horn-like kuppe lower end are 0.2mm apart from narrow-mouthed bottle bottom wall.Water sample after reduction flow velocity after water conservancy diversion straight tube, helical form conduit by horn-like kuppe by being slowly injected into inside narrow-mouthed bottle, due to horn-like kuppe inwall and the active force and reaction force of narrow-mouthed bottle bottom wall, reduce impulsive force of the current to bottom wall, effectively control bubble produces, slowly air in bottle is extruded by rising liquid level, water conservancy diversion pipe close is inserted after filling water sample.A kind of novel biochemical oxygen demand sampling bottle of the present utility model is simple in construction, easy to use, can uniformly exclude air in bottle will not produce a kind of sampling bottle of other interference again, the storage for water sample mesophytization oxygen demand provides a kind of novel sampling bottle.
Description
Technical field
A kind of sampling bottle is the utility model is related to, is made for surface water and the storage of the water sample of waste water mesophytization oxygen demand project
With.Belong to environmental monitoring technology field.
Background technology
When carrying out surface water and waste water mesophytization oxygen demand project measure in environmental monitoring, thin mouth vial is used to make
It is used to store water sample sample for sampling bottle.According to Specifications of Monitoring Technology, sampling bottle should be filled and reduce air surplus in bottle, purpose
It is to suppress bioactivity, reduces the influence to sample mesophytization oxygen demand project in transportation.Common practice is to utilize post
After shape samplers sample water sample, the silica gel catheter carried using sampler is put in narrow-mouthed bottle, prolongs inwall by water sample by sampler
Inject in sampling bottle, silica gel catheter is taken out after filling.Thus easily cause current injection it is too fast, sampling bottle inwall is easily retained
Bubble, bubble can not exclude in time in bottle, while easily cause silica gel pipe outer wall and produce interference effect to water in bottle sample, so as to lead
Cause to have an impact the measure of biochemical oxygen demand (BOD).
The content of the invention
The utility model is a kind of simple in construction to solve the problems, such as to provide in above-mentioned background technology, easy to use, can be by bottle
Interior additional air uniformly excludes that a kind of sampling bottle of other interference effects, the storage for water sample mesophytization oxygen demand will not be produced again
Deposit and provide a kind of novel sampling bottle.
To reach above-mentioned purpose, the technical solution of the utility model is：
A kind of novel biochemical oxygen demand sampling bottle, including narrow-mouthed bottle（3）With water sample guiding device, it is characterised in that in thin mouth
Bottle cap（2）Place's installation water sample guiding device, guiding device is by water conservancy diversion pipe close（1）, water conservancy diversion straight tube（6）, helical form mozzle
（4）, horn-like kuppe（5）Composition.Wherein helical form mozzle（4）Both ends connect water conservancy diversion straight tube（6）With horn-like kuppe
（5）, horn-like kuppe（5）Lower end is 0.2 millimeter apart from narrow-mouthed bottle bottom wall, 10 centimetres of helical form water conservancy diversion length of tube.Water conservancy diversion is straight
Pipe front end connects water conservancy diversion pipe close（1）, end connection helical form mozzle（4）.Helical form mozzle（4）End connection is horn-like to be led
Stream cover（5）.
The beneficial effects of the utility model are：It is simple in construction to provide one kind, it is easy to use, can be by additional air in sampling bottle
Uniformly exclude that a kind of sampling bottles of other interference effects will not be produced again, a kind of new adopt is provided for measure biochemical oxygen demand (BOD)
Sample bottle.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, water conservancy diversion pipe close（1）, narrow-mouthed bottle lid（2）, narrow-mouthed bottle（3）, helical form mozzle（4）, horn-like kuppe
（5）, water conservancy diversion straight tube（6）.
Embodiment
The utility model is further illustrated with implementation below in conjunction with the accompanying drawings.To surface water and the aerobic quantifier of waste water mesophytization
When mesh gathers sample, water conservancy diversion pipe close is pulled out first, columnar sampler silica gel catheter is directly connected at sampling bottle water conservancy diversion straight tube, adopted
Water sample is slowly injected into carefully by reducing flowing velocity after water conservancy diversion straight tube, helical form mozzle by horn-like kuppe in sample device
Inside mouth bottle.Due to horn-like kuppe inwall and the active force and reaction force of narrow-mouthed bottle bottom wall, current are reduced to bottom wall
Impulsive force, reduce bubble and produce.Slowly air in bottle is extruded by rising liquid level, water conservancy diversion pipe close is inserted after filling water sample.
