Abstract
The invention discloses a draught fan of a fume cupboard; the draught fan is characterized by comprising a motor, an impeller, a shell, an air inlet and an air outlet, wherein the motor and the impeller are respectively arranged inside and outside the shell; the motor is connected with the impeller through a transmission shaft; and the air inlet and the air outlet are arranged on the shell. As the impeller, the shell, the air inlet and the air outlet are made of a PVC (Polyvinyl Chloride) material, the parts have the advantages of being difficult to pollute and corrode; a three-gear variable-speed motor with the low voltage of 220-volt alternating current and 300 watts of power is adopted as the motor so that the revolving speed of the motor can be selected according to the size of the fume cupboard, and the purpose of energy saving is achieved; and therefore, the operating cost and the maintenance cost are greatly saved.
Description
Technical field
The present invention relates to the experiment equipment field, be specifically related to a kind of Fume hood induced draft fan.
Background technique
Fume hood mainly is to be used for test places such as all kinds of chemical laboratories and biology laboratory; Purpose is that all kinds of waste gas and the smog guaranteeing in the experimentation to be produced can be disposed to outdoor or exhaust gas treating tower fully; Can not pollute, guarantee experimenter's safety laboratory environment.Therefore, Fume hood should be equipped with induced draft fan effectively.
The induced draft fan that current Fume hood uses adopts centrifugal blower and axial-flow blower mostly, uses them all having defective in varying degrees, and centrifugal blower is cost height but also weak effect not only, and noise of axial flow fan greatly very easily corrodes.In addition, adopt centrifuge and axial-flow blower need stringing, thereby increased the construction cost and the difficulty of construction of exhausting system in the laboratory, also further influenced environmental hygiene and the Security of experiment in the laboratory.
Summary of the invention
In view of this, the invention discloses a kind of Fume hood blower fan, reached cost low, be difficult for the effective purpose of burn into exhausting.
For achieving the above object, technological scheme of the present invention is following:
A kind of Fume hood blower fan is characterized in that, is made up of motor, impeller, shell, intake grill and exhaust outlet; Said motor and said impeller are arranged at the outside and inner of said shell respectively; Said motor is connected through transmission shaft with said impeller; Said intake grill and said exhaust outlet are arranged on the said shell.
Preferably, said shell, said intake grill and said exhaust outlet are the PVC welding fabrication.
Preferably, said impeller is the PVC molding and forming.
Preferably, said motor is the three class gear shift motor of 300 watts of 220 volts of Alternating Current Power Supplies, power.
Can find out from above-mentioned technological scheme; Shell, impeller, intake grill and the exhaust outlet of the disclosed a kind of Fume hood blower fan of the present invention can not caused corrosion by waste gas and the smog that long-term experiment produced; Said low voltage motor is rotating speed adjustable according to actual needs, thereby has reduced operating cost and maintenance cost.Improved the exhausting effect of Fume hood self greatly, more environmental protection, more energy-conservation.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technological scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the disclosed a kind of Fume hood blower fan structure schematic representation of the embodiment of the invention;
Fig. 2 is the disclosed a kind of Fume hood blower fan structure schematic top plan view of the embodiment of the invention.
The title of the corresponding part that numeral among the figure or letter are represented:
1, motor 2, impeller 3, shell 4, intake grill 5, exhaust outlet
Embodiment
To combine accompanying drawing below, the technological scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiments.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
The invention discloses a kind of Fume hood blower fan, with reach cost low, be difficult for the effective purpose of burn into exhausting.
As depicted in figs. 1 and 2, described Fume hood blower fan is made up of motor 1, impeller 2, shell 3, intake grill 4 and exhaust outlet 5; Said motor 1 is arranged at the outside and inner of said shell 3 respectively with said impeller 2; Said motor 1 and said impeller 2 are connected through transmission shaft; Said intake grill 4 is arranged on the different facial of said shell 3 with said exhaust outlet 5.Wherein, said motor 1 can adopt coupling to be connected with said impeller 2, and to this, the present invention does not do qualification.
Working principle of the present invention is following: when Fume hood needs exhausting, and starting motor 1,2 runnings of motor 1 impeller; Waste gas and smog are inhaled into shell 3 inside through intake grill 4 in the Fume hood; Under the effect of impeller 2, air flow direction exhaust outlet 5, and then with waste gas and smog emission to outdoor or exhaust gas treating tower; Can not pollute, guarantee experimenter's safety laboratory environment.
Because what motor 1 adopted is 220 volts of Alternating Current Power Supplies of general lighting voltage, the three class gear shift motor that power is 300 watts so can select rotating speed of motor according to the size of Fume hood, when Fume hood is big, can be selected high speed operation; When Fume hood hour, can select low cruise, thereby practice thrift operating cost greatly, really accomplished not only environmental protection but also energy-conservation.
When in Fume hood, doing chemical experiment or Bioexperiment; Waste gas that produces and smog mostly have pollution and corrosivity; The impeller 2 of the disclosed Fume hood blower fan of the present invention, shell 3, intake grill 4 and exhaust outlet 5 are shaped for the PVC material; Make these parts have and be difficult for contaminated and advantage that be difficult for being corroded, thereby also practiced thrift cost of production and maintenance cost greatly.Certainly, above-mentioned parts also can adopt other not perishable material that can meet the demands again to be shaped, and these will can not be limited within protection scope of the present invention.
For of the improvement of the disclosed Fume hood blower fan of the present invention to traditional centrifugal blower and axial-flow blower; Not only increased the exhausting effect of Fume hood self; Also avoided experimental situation is polluted; More effectively guarantee environmental hygiene and the Security of experiment in the laboratory, guaranteed experimenter's Security, greatly reduced the construction cost and the difficulty of construction of exhausting system in the laboratory; And can select rotating speed of motor according to the size of Fume hood, operating cost has been practiced thrift in the motor operation of low voltage greatly, has reduced the benefit pipe correlative charges and the difficulty of construction of exhausting system in the former laboratory.
More than be description,, make related domain professional and technical personnel can realize or use the present invention through above-mentioned explanation to the disclosed embodiments to the embodiment of the invention.Multiple modification to these embodiments will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments among this paper.Therefore, the present invention will can not be restricted to these embodiments shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
