Abstract
The invention relates to an air speed stabilizing device for a range hood, which is arranged on an exhaust pipeline of a range hood, belonging to the technical field of detection and analysis of tobacco. The air speed stabilizing device for the range hood consists of an exhaust buffer of which one end is connected with an exhaust pipeline (5), and a secondary exhaust fan (6) which is connected with the exhaust buffer through the exhaust pipeline (5) and is provided with an air purifying device (7) at the air outlet end, wherein the exhaust buffer consists of a buffering box (1), a sponge body (2) arranged in the buffering box (1) and air suction pipes (3, 4) arranged at one end of the buffering box (1). The air speed stabilizing device for the range hood is made of market-purchased products and materials with the conventional method. The air speed stabilizing device has the advantages of simple structure, low cost, stable air speed and good effect.
Description
Technical field:
The present invention relates to a kind of smoking machine wind speed stabilising arrangement that places on the smoking machine air draft pipeline, belong to tobacco check and analysis technical field.
Background technology:
The raising of the Along with people's level of consumption, the enhancing of health perception, also increasingly high for the check and analysis requirement of various compositions in the tobacco.The detection of cigarette chemical constitution comprises two types of tobacco component and smoke components, and wherein, smoking machine is the indispensable link of all smoke components testings, carries out various chemical composition analysis after capturing the flue gas of cigarette burning through smoking machine.Therefore, the stability of smoking machine work has material impact to the accuracy of flue gas check and analysis.Smoking machine is when work, and the stability of exhaust system is most important to the influence of smoking machine flue gas trapping accuracy.Generally speaking, the smoking machine exhaust system motor exhaust that relies on smoking machine to carry is discharged to waste gas outdoor.Because outdoor airflow influence; And one through type pipeline configuration of exhaust system; Usually make that the wind speed of smoking machine is unstable; The detected wind speed of anemoscope is up and down, and smoking machine is difficult to be stabilized to normal operation in the standard wind speed scope, also has a strong impact on the accuracy and the stability of smoking machine work.For this reason, the inventor has developed a kind of device that is used for stablizing the air draft wind speed to the problem that existing smoking machine exhaust system exists.
Summary of the invention:
The objective of the invention is to overcome the deficiency of prior art, and provide a kind of simple in structure, working stability is reliable, integrates the smoking machine wind speed stabilising arrangement of stablizing wind speed and auxiliary air-exhausting function.
The objective of the invention is to realize like this:
The smoking machine wind speed stabilising arrangement that places on the smoking machine air draft pipeline of the present invention; The air draft impact damper that is connected with exhaust duct (5) by an end, and be connected with the air draft impact damper and its outlet air end is provided with secondary air draft blower fan (6) composition of air cleaning unit (7) through exhaust duct (5).Wherein: the air draft impact damper is by cushioning casing (1), placing the cavernous body (2) that cushions casing (1), aspiration channel (3, the 4) formation that places buffering casing (1) one end.
Smoking machine wind speed stabilising arrangement of the present invention, the product and the material that adopt market to buy prepare by conventional method.
Principle of work of the present invention is: the waste gas of smoking machine is extracted in the impact damper through carrying blower fan; Because the volume of impact damper is much bigger than pipeline, the space that air-flow arrives increases suddenly, plays the effect of buffering and savings air-flow; After air-flow is saved bit by bit certain pressure; Waste gas flows to discharge pipe, under the suction of secondary air draft blower fan, discharges outdoor with stable flow velocity.
The invention has the advantages that: simple in structure, cost is low, wind speed is stable, effect is good.
Description of drawings:
Fig. 1 is one-piece construction of the present invention and duty configuration schematic diagram.
Embodiment
Below in conjunction with accompanying drawing invention is explained.
The smoking machine wind speed stabilising arrangement that places on the smoking machine air draft pipeline of the present invention; The air draft impact damper that is connected with exhaust duct 5 by an end, and be connected with the air draft impact damper and its outlet air end is provided with secondary air draft blower fan 6 compositions of air cleaning unit 7 through exhaust duct 5.Wherein: the air draft impact damper by buffering casing 1, place buffering casing 1 cavernous body 2, place the aspiration channel 3 and 4 of buffering casing 1 one ends to constitute.
Smoking machine wind speed stabilising arrangement of the present invention, the product and the material that adopt market to buy prepare by conventional method.
Wherein: secondary air draft blower fan 6 is installed in apart from 1～2 meter of air outlet for buying, and maximum wind velocity is 260,000 meter per seconds.Baffle-box 1 is long to be 800mm, and wide is 500mm, and height is 500mm, and air draught import 3 and 4 pipe diameter are 100mm, and the diameter of exhaust duct 5 is 200mm.
The course of work of the present invention:
The waste gas that original smoking machine work produces through original air exhauster suction and entering air-suction duct 3 and 4, pours into baffle-box main box 1 then; Because cabinet space increases, air-flow slows down and is detained, along with constantly pouring into of waste gas; Air-flow is slowly through cavernous body 2, and the slack-off air-flow of speed arrives the inlet of exhaust duct 5, because the strong pumping of secondary air draft blower fan 6; Air-flow quickens and through exhaust duct 5, after air cleaning unit 7 filters, discharges outdoor.
After using apparatus of the present invention, do not reduced by 30～50% before the gas flow measurement value coefficient of variation on the smoking machine is more used, made that the smoking machine anemoscope is more stable, impelled flue gas trapping work more reliable, improved the accuracy of smoke components check and analysis.
Claims (2)
1. smoking machine wind speed stabilising arrangement; It is characterized in that placing the smoking machine wind speed stabilising arrangement on the smoking machine air draft pipeline; The air draft impact damper that is connected with exhaust duct (5) by an end, and be connected with the air draft impact damper and its outlet air end is provided with secondary air draft blower fan (6) composition of air cleaning unit (7) through exhaust duct (5).
2. the described smoking machine wind speed of claim 1 stabilising arrangement is characterized in that the air draft impact damper is by cushioning casing (1), placing the cavernous body (2) that cushions casing (1), aspiration channel (3, the 4) formation that places buffering casing (1) one end.
