Description
Technical field
The utility model belongs to cigarette smoke physical and chemical inspection technical field, is specifically related to a kind of atmospheric pressure automatic regulating apparatus changing highlands atmospheric environment and affect smoking machine.
Background technology
It is reported, cigarette smoke contains 5000 Multiple components, wherein comprises the condensed-nuclei aromatics that trace is harmful.The objectionable impuritiess such as the condensed-nuclei aromatics that cigarette burning produces are present among tar.Because the determination step of condensed-nuclei aromatics is various, analysis efficiency is low, cannot be used widely in reality performs.By contrast, tar measures then fast fairly simple, therefore in the world the height of current tar content as one of the index of the security of evaluating cigarette.
The measurement result of tar content in cigarette is built consensus by the impact of atmospheric pressure, its Influencing Mechanism is that atmospheric pressure difference causes oxygen content in the air of same volume also different, can have an impact to the burning of cigarette undoubtedly, correspondingly analysis result be affected.In more international and domestic common experimental study processes, and in daily cigarette product quality supervision and test work, all find that the measurement result of laboratory, high altitude localities tar content in cigarette and carbon monoxide in flue gas amount and laboratory, normal atmospheric pressure area exist significant difference.
European Union thinks that in 2004 tar content in cigarette, nicotine content in smoke and carbon monoxide in flue gas amount are of paramount importance 3 fume indications of cigarette, and starts to control the highest limitation.Cigarette industry China's " cigarette " national standard after 10 years development proposes bound control overflow to tar content in cigarette, nicotine content in smoke and carbon monoxide in flue gas amount.
How to solve the difference of different regions test result, for cigarette product quality supervision and manufacturing enterprise's internal quality control all most important, carry out specific aim research and propose practicable solution for the cigarette industry quality of production control significant.
Utility model content
For the deficiencies in the prior art, the utility model proposes a kind of Pressure chamber that can be used for Different Altitude Regions cigarette smoke physical and chemical inspection.
The purpose of this utility model is realized by following technical measures:
Change the Pressure chamber that highlands atmospheric environment affects smoking machine, for placing smoking machine wherein and support equipment carries out cigarette smoke physical and chemical inspection, comprising base and being arranged on the warehouse on base; The front of described warehouse is provided with the first door and the second door of splitting setting, is also provided with the 3rd door below the first door and the second door; The top of described warehouse is provided with inlet end compressed air interface, is provided with pressurizing valve with the pipeline of inlet end compressed air interface; Described warehouse top is also provided with blowdown valve; The side of described warehouse is also provided with exhaust end fume emission interface, and the seam crossing on described warehouse is tightly connected.
Further, described base is provided with universal wheel and horizontal adjustment bolt.
Further, described warehouse is provided with touch screen controller.
Further, described door edge is provided with integrated pressure proof sealing strip.
Further, the wall of described warehouse is make with the steel plate of reinforcement.
Further, the edge of the wall of described warehouse adopts coupling type structure, and centre is integral type sealing strip, and along with the rising of warehouse internal pressure, the sealing property between interconnective two walls increases.
Further, described warehouse is demountable structure.
The utility model adopts partition principle, and inside have employed clean steel shelf structure, dismountable modular design, at laboratory Assembling, solves due to problem that is bulky, that cannot enter.The base of Pressure chamber installs four universal wheels and horizontal adjusting bolt, overcomes a difficult problem for short-distance movement difficulty and horizontal Installation and Debugging in laboratory.During Pressure chamber work, warehouse inside is in high pressure conditions, and it is inevitable that very large warehouse produces microdeformation, but the warehouse caused thus leaks gas, sealing property is deteriorated and must be resolved.Adopt the sealing problem between local characteristics principle process warehouse wall, wall edges of plate adopts coupling type structure,
Between be integrated pressure proof sealing strip, utilize the pressure of warehouse inside outwards to push wall steel plate, pressure is higher, coupling type structure produce strength larger, sealing is better.The sealing problem of door and doorframe, adopt precharge principle, doorframe is fixing steel frame construction, is integrated pressure proof sealing strip between doorframe and door, utilizes door latch mechanism precharge sealing strip, seals.Pressure chamber chamber portions is little as far as possible under the prerequisite meeting normal use, to save the energy, to shorten the time reaching specified pressure value, increases work efficiency.Adopting and remove principle, smoking machine is taken the servicing unit that volume is larger---blower fan and variable-frequency speed-regulating controller are installed to Pressure chamber outside, neither affect use, have saved warehouse space simultaneously.Smoking machine will be placed in Pressure chamber inside, and carries out regular job, maintenance to smoking machine.Adopt the local property principle of smoking machine operation, at Pressure chamber Front-end Design three road door, can open (inserting smoking machine) simultaneously, also can open separately (operate, safeguard smoking machine).
Compared to prior art, the utility model Pressure chamber directly raises the pressure of smoking machine test environment, to meet the pressure requirements of national regulations atmospheric environment, eliminates highlands atmospheric environment detects data impact on smoking machine.The experimental situation of different atmospheric pressure can be simulated in same laboratory, complete corresponding flue gas analysis experiment.
