Abstract

The invention discloses a sinuosity type single port gravity settling air clarifying device which is a cover body comprising a inner space. The cover body has an up-down air passageway which upper port is communicated to a through hole set on wall of cover body upper part. Outer contour outline shape and size of microbial cultivation pipe port are same to inner contour outline shape. An air hole is set on port of the microbial cultivation pipe. The cover incorporating the invention is rotatablely mounted on port of microbial cultivation pipe which can communicate air hole of microbial cultivation pipe and the through hole of the cover and also can enclose air hole of microbial cultivation pipe and the through hole of the cover to isolate the microbial cultivation pipe from the outer air. Microbiology in the air is difficult to enter the cultivation pipe to pollute the culture medium so the safety of the microbial cultivation is improved because the air exchanging in and out the microbial cultivation pipe is carried out in diffusion type and not generating turbulent flow or vortex flow.

Description

Blending type single-end gravity settling air cleaning facility

Technical field

The present invention relates to a kind of air cleaning unit of microorganism culturing device, particularly a kind of blending type single-end gravity settling air cleaning facility.

Background technology

At present, the cultivation of microorganism is to be inoculated in the aseptic culture medium in culture dish or the culture tube desiring cultured microorganism kind or thing to be checked, the culture dish or the culture tube of substratum will be housed then, put into Pei Yang Kuang, again Pei Yang Kuang is put in the microbiological incubator afterwards and cultivates, this microbiological incubator has forced ventilation equipment, force air in the microbiological incubator is flowed, this kind mode has following shortcoming, because of the air in the microbiological incubator is a forced-flow, air produces turbulent flow or eddy current in microbiological incubator, so, various microorganisms will enter in the culture dish from the slit of culture dish lid in the air, have polluted substratum, make cultured microorganism easily contaminated and impure, cause the microorganism culturing failure.

Summary of the invention

The objective of the invention is to solve existing microbiological incubator and make the easy contaminated problem of cultured microorganism, and provide a kind of overcome above-mentioned shortcoming, can prevent the contaminated blending type single-end gravity settling air cleaning facility of cultured microorganism.

The present invention is a lid with internal space, and the zigzag air passageways on this lid has to descending offers through hole on the wall on lid top, and the upper port of air passageways is communicated with this through hole.

Use of the present invention is:

The outer contoured shape of the mouth of pipe of microorganism culturing pipe is identical with the interior outline shape of lid, the corresponding cooperation of size, the mouth of pipe place of microorganism culturing pipe offers ventilating pit, upper shield of the present invention is on the mouth of pipe of microorganism culturing pipe, the two can relatively rotate, the ventilating pit at the mouth of pipe place of microorganism culturing pipe is communicated with the through hole of lid, at this moment, the air passageways of air outside by lid to down and on complications enter in the microorganism culturing pipe, also can make the ventilating pit at the mouth of pipe place of microorganism culturing pipe leave the through hole of lid, make microorganism culturing pipe and extraneous air isolated.

Principle of work of the present invention is:

The mouth of pipe place that upper shield of the present invention is had the culture tube of microorganism in inoculation, and culture tube is communicated with extraneous air, microorganism absorbs oxygen in cultivating reproductive process, give off carbon dioxide, and plant is absorbing carbon dioxide, emits oxygen, cause in the culture tube carbon dioxide in air and concentration of oxygen ratio with the carbonic acid gas in the extraneous air and concentration of oxygen ratio imbalance, according to the second law of thermodynamics, generation concentration difference between air that culture tube is interior and the air outside and spreading; The setting of tortuous air passageways, make before extraneous air enters in the culture tube, a process that contacts with the air passageways inwall is arranged, and the purpose of this contact process is to make koniology and microorganism sedimentation or stick on the wall and can not enter into culture tube, plays the effect that purifies air.

Embodiment

See also Fig. 1, Fig. 2, shown in Figure 3, be the first embodiment of the present invention, it is a lid 1 with internal space, in this embodiment, lid 1 with internal space is a taper lid, offer through hole 3 on the wall on taper lid top, be arranged with a ventpipe 2 on the outer wall of taper lid, the lower port of this ventpipe 2 is communicated with space outerpace, the through hole of offering on upper port and the conical lid body wall 3 is communicated with, this ventpipe 2 promptly is an air passageways, and this ventpipe 2 also can be dioptric type and be attached on the outer wall of taper lid; The inner top of taper lid is down protruding 4 shapes, and the water vapor of rising after the condensation, can drop onto in the microorganism culturing pipe from this time protruding 4 herein again.

See also shown in Figure 4, be the second embodiment of the present invention, it is a lid 1 with internal space, in this embodiment, lid 1 with internal space is a double layered cone lid, the double layered cone lid is to be formed by internal layer taper lid 11 and outer taper lid 12 fits, offer through hole 3 on the wall on internal layer taper lid 11 tops, be arranged with division board 13 between internal layer taper lid 11 and the outer taper lid 12, the division board 13 of this winding forms air passageways 5 with the space between internal layer taper lid 11 and the outer taper lid 12, the lower port of this air passageways 5 is communicated with space outerpace, the through hole of offering on upper port and internal layer taper lid 11 walls 3 is communicated with, the inner top of internal layer taper lid 11 is protruding 4 shapes down, the water vapor that rises after the condensation, can drop onto in the microorganism culturing pipe from this time protruding 4 herein again.
