Abstract
一种负压可调式排风装置，它由电动鼓风机、风箱、螺丝杆构成，所述的风箱是透明风箱，电动鼓风机的出风口嵌入于该透明风箱的入风口内，该透明风箱主风道的下端有一带倾斜角度的风箱吸风口，可上下调节位置的负压调节板与靠近电动鼓风机出风口一侧的风箱吸风道连接。在吸风道与主风道的结合部位安装了负压调节板，可将负压排风效果调整到最佳状态的负压可调式排风装置。克服了吸风道内壁形成涡流的现象。由于风箱设置为透明风箱，通过透明风箱可清楚的观察到风道内的排风情况。具有低成本、组合方便、使用灵活等特点。可广泛应用于机械抛光、集成电路腐蚀制板、化学实验室、烹饪油烟等的排风。
A negative pressure adjustable exhaust device, which is composed of an electric blower, a bellows, and a screw rod. The bellows is a transparent bellows, and the air outlet of the electric blower is embedded in the air inlet of the transparent bellows. The main air duct of the transparent bellows There is a bellows air suction port with an inclined angle at the lower end of it, and the negative pressure regulating plate which can adjust the position up and down is connected with the bellows air suction duct on the side near the air outlet of the electric blower. A negative pressure regulating plate is installed at the junction of the suction duct and the main air duct, which can adjust the negative pressure exhaust effect to the best state of the negative pressure adjustable exhaust device. The phenomenon of vortex formation on the inner wall of the suction duct is overcome. Since the bellows are set as transparent bellows, the exhaust air condition in the air duct can be clearly observed through the transparent bellows. It has the characteristics of low cost, convenient combination and flexible use. It can be widely used in exhaust of mechanical polishing, integrated circuit corrosion board, chemical laboratory, cooking fumes, etc.
Description
Technical field
The present invention relates to the adjustable air exhausting device of a kind of negative pressure, belong to air draft
Technical field.
Background technology
Existing ventilation and negative pressure ventilation device, function singleness, mostly be culinary smoke exhaust, disclose a kind of " jet, negative pressure, suction guide type smoke exhaust " as Chinese patent 03239020.3, although its power consumption is little, exhaust air rate is big, but because its negative pressure air quantity size is fixing, non-adjustable, in the course of work, very easily produce vortes interference air draft quality.And because whole oil-smoke expulsion pipe is the opaque cylindrical shell of sealing, so can't observe air channel internal operation situation.
Summary of the invention
The technical problems to be solved in the utility model is the defective at above-mentioned prior art, a kind of employing air-spray principle is provided, at the binding site of air draught road and main air duct the negative pressure adjustable plate has been installed, the ventilation and negative pressure ventilation effect can have been adjusted to the adjustable air exhausting device of negative pressure of optimum state.
Solve the problems of the technologies described above by the following technical solutions: the adjustable air exhausting device of a kind of negative pressure, it is made of electric blower, bellows, lead screw, its structural feature is: described bellows are transparent bellows, the air outlet of electric blower is embedded in the air intake vent of these transparent bellows, there is the transparent bellows inlet scoop at a band angle of inclination lower end of this transparent bellows main air duct, but the negative pressure adjustable plate of up-down adjustment position is connected with the transparent bellows air draught road of close electric blower air outlet one side.
Owing to adopted technique scheme, the electric blower of this device does not directly contact with being discharged medium, the adverse effect of having avoided dust, high temperature, greasy dirt, etchant gas etc. to cause.At the binding site of air draught road and main air duct the negative pressure adjustable plate has been installed, the ventilation and negative pressure ventilation effect can have been adjusted to the adjustable air exhausting device of negative pressure of optimum state.Overcome the phenomenon of air draught road inwall formation eddy current.Because bellows are set to transparent bellows, can clearly observe air draft situation in the air channel by transparent bellows.This device has characteristics such as low cost, combined and instant, use be flexible.Can be widely used in the air draft of machine glazed finish, integrated circuit corrosion making sheet, chemical laboratory, cooking fume etc.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model adjustable plate structural representation.
Among the figure, electric blower 1, transparent bellows air intake vent 2, blower outlet 3, transparent bellows 4, transparent bellows main air duct 5, transparent bellows air outlet 6, transparent bellows air draught road 7, transparent bellows inlet scoop 8, negative pressure adjustable plate 9, packing ring 10, nut 11, lead screw 12, long via hole 13.
The specific embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is further described.
Referring to accompanying drawing 1, the utility model is made up of electric blower 1, transparent bellows 4, negative pressure adjustable plate 9, packing ring 10, nut 11, lead screw 12.Transparent bellows 4 are by transparent bellows air intake vent 2, transparent bellows main air duct 5, and transparent bellows air outlet 6, transparent bellows air draught road 7, transparent bellows inlet scoop 8 is formed.Transparent bellows air outlet 6 is positioned at the front end of transparent bellows main air duct 5.The air outlet 3 of electric blower 1 is embedded in the air intake vent 2 of these transparent bellows 4.There is the transparent bellows inlet scoop 8 at a band angle of inclination lower end of this transparent bellows main air duct 5.Be provided with long via hole 13 near on the transparent bellows air draught road 7 of electric blower air outlet 3 one sides, referring to Fig. 2, one lead screw 12 with fixation is arranged on the negative pressure adjustable plate 9, but negative pressure adjustable plate 9 is the up-down adjustment position as required, is connected fastening with the long via hole 13 on the transparent bellows air draught road 7 of packing ring 10, nut 11 and air outlet 3 one sides of close electric blower 1.Lead screw 12 on the negative pressure adjustable plate 9 can be along the long via hole 13 upper and lower regulated at will positions of transparent bellows air draught road 7 one sides.Because bellows are transparent bellows, can with the naked eye observe the working condition in the air channel at any time.
