The compressed air liquid knockout
Technical field
The utility model relates to a kind of liquid knockout, particularly a kind of liquid knockout that utilizes compressed air to remove the article surface residual liquid.
Background technology
At present in actual production, in order to remove the residual liquid on article surface or processing work surface, it is main that what adopt is liquid collecting place that the compressed air that will have a certain pressure is directly injected to article surface, utilize compressed-air actuated pressure and speed that the residual liquid of article surface is dispelled in the ambient air, under the more situation of liquid, be furnished with independent aspirator in addition again, and then reach the purpose of removal.Disclose a kind of method and apparatus that article dewater that is used for as patent of invention 03815673, this method is through aspirator with article delivery, when the inlet of aspirator is passed through on the surface with residual liquid, described surface to these article guides one compressed air jet at least, with with near the air of liquid this aspirator inlet is transferred on the described surface of these article, operate this aspirator simultaneously and be drawn in the inlet of aspirator with the air that will contain liquid.Also can utilize the principle of vibration, make the liquid of article surface produce heat by vibration, so atomizing, perhaps adopt high frequency compressed air oscillating jet, be directly injected to article surface, make the atomization of liquid of article surface, reach the purpose of removal.More than required time of these methods all longer, and easily liquid is dispelled other body surface, pollute other article and surrounding environment, structure is also comparatively complicated.
Summary of the invention
The utility model main purpose is to address the above problem and is not enough, a kind of liquid knockout is provided, utilize compressed air in suction pipe, to flow to make and produce negative pressure in the suction pipe, and then the residual liquid of article surface is drawn onto in the suction pipe and with compressed air discharges, simple in structure, speed is fast, and the efficient height is easy to use.
For achieving the above object, described compressed air liquid knockout:
Comprise a suction pipe with suction inlet and outlet, the central axis of described suction inlet and outlet is positioned at same plane and vertical mutually, on the suction pipe between described suction inlet and the outlet, connect an arm, described arm and described suction pipe internal communication, described arm is connected with air compressor by blowpipe, forms an angle theta between the central axis of described arm and the central axis of described outlet.
The angle theta that forms between the central axis of described arm and the central axis of outlet is 10 ° to 20 °, and optimum value is 15 °.Described outlet is connected with liquid collecting container by tube connector, or directly is connected with sewer.
Content to sum up, the utility model advantage compared with prior art are by simple arm design, compressed air to be introduced in the suction pipe, make and produce negative pressure in the suction pipe, and then the residual liquid of article surface is drawn onto in the suction pipe and discharges, simple in structure, speed is fast, and the efficient height is easy to use.

A suction pipe and a pipe composite structure schematic diagram in Fig. 2 the utility model.
As depicted in figs. 1 and 2, suction inlet 1, outlet 2, suction pipe 3, arm 4, blowpipe 5, air compressor 6, tube connector 7, liquid collecting container 8.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As depicted in figs. 1 and 2, described compressed air liquid knockout, comprise a suction pipe 3 with suction inlet 1 and outlet 2, the central axis of suction inlet 1 and outlet 2 is positioned at same plane and vertical mutually, on the suction pipe 3 between suction inlet 1 and the outlet 2, connect an arm 4, arm 4 and suction pipe 3 internal communication, arm 4 is connected with air compressor 6 by blowpipe 5, forms an angle theta between the central axis of the central axis of arm 4 and outlet 2.
Air through air compressor 6 compressions, enter in the arm 4 by blowpipe 5, when the compressed air with certain pressure and flow velocity is flowed through the crossing of suction pipe 3 and arm 4 inside, can produce negative pressure in crossing, at this moment the residual liquid of article surface will be inhaled in the suction pipe 3 from suction inlet 1 under the atmospheric effect in the external world, and along with compressed air is discharged from outlet 2 together.Angle theta is generally 10 ° to 20 °, and optimum value is 15 °, and angle theta is excessive or too small, all can make the negative pressure quantity not sufficient, and adsorption rate is slow, and adsorption effect is bad.
The material of suction pipe 3 can be selected according to the liquid that will remove, and the material of general suction pipe 3 can be selected plastics or stainless steel, if during oil suction, can adopt oil resistivity rubber tube preferably.The caliber of suction pipe 3 determines that according to compressed-air actuated pressure size in general practical application, can adopt pressure is the compressed air of 0.6MPa, and compressed-air actuated pressure is big more, just can select the thicker suction pipe of caliber 3, and adsorption rate will improve like this.
This suction pipe 3 is simple in structure, in light weight, and the operator can directly be held on the suction pipe 3 with hand, and the liquid that where is it need be removed just with suction inlet 1 alignment liquid, can siphon away liquid, and is easy to use.The operator uses for convenience, also a handle can be installed on suction pipe 3.
In addition, for the liquid that makes suction directly is not discharged in the air, environment around avoiding polluting especially when amount of liquid is many, can be connected by tube connector 7 outlet 2 with liquid collecting container 8, the liquid that sucks is collected, can concentrate discharging, also can recycling, collect if do not need, then tube connector 7 directly can be connected with sewer, the liquid that sucks directly is discharged in the sewer.
This compressed air liquid knockout also can be done another kind of the improvement, both has been applied to air wetting, and suction pipe sucks water from reservoir of water, is discharged in the environment that needs humidification by outlet with compressed air, thereby gives air wetting.
As mentioned above, given in conjunction with the accompanying drawings and embodiments scheme content can derive the similar techniques scheme.In every case be the content that does not break away from technical solutions of the utility model, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of technical solutions of the utility model according to technical spirit of the present utility model.
