Description
Technical field
The present invention relates to a kind of combustion experimental devices for preventing powder from reuniting in transit, in particular to a kind of to utilize motor
The combustion experimental device that powder is reunited during transportation is prevented, mechanical engineering field is belonged to.
Background technique
With being constantly progressive for science and technology and popularizing for automated production mode, powder feeder unit is in many occasions
It is used widely, such as metallurgy, medical treatment and each field of food processing.Stability when people work to powder feeder unit simultaneously
More stringent requirements are proposed, most basic requirement be powder supply must it is continuous and cannot breaking down property interrupt.
And in currently used powder feeder unit, meal outlet mostly uses capillary to connect, and since capillary diameter is too small, holds
Easily there is the case where powder reunion blocking capillary, powder supplies is caused to be interrupted.It therefore, is the continuous of guarantee powder supplies
Smooth, designing a kind of can effectively prevent the powder feeder unit that powder is reunited in transit and is very important.
Summary of the invention
The problem of the purpose of the present invention is to solve powder reunion blocking capillaries, providing one kind prevents powder from transporting
The combustion experimental device of middle reunion, the combustion experimental device are made of powder feeder unit, igniter and detection device three parts.
The purpose of the present invention is what is be achieved through the following technical solutions.
A kind of combustion experimental device for preventing powder from reuniting in transit, including powder feeder unit, igniter and detection dress
It sets.Powder feeder unit includes high pressure gas cylinder, pressure reducer, valve, flowmeter, hose, air inlet pipe, powder tank, motor, stirring bar,
Capillary and pipeline are several；Igniter includes reaction vessel, housing, pedestal and ignition wire；Detection device includes spectrometer.
Connection relationship: in powder feeder unit, between high pressure gas cylinder, pressure reducer, valve and flowmeter, pipeline phase is successively used
Connection, air are sent into powder tank from high pressure gas cylinder by pipeline transportation and air inlet pipe.It is opened on the bottle cap of powder tank
There are two apertures, install air inlet pipe and capillary herein, are respectively used to air inlet and out powder.The bottom of powder tank is also provided with small
Stirring bar is protruded into powder tank from the aperture, and guarantees that movement interference does not occur with air inlet pipe and capillary in it by hole.Agitation
Stick is fixedly connected with motor, and the two keeps rotating synchronously, and motor is mounted on the bottom of powder tank, and should be guaranteed that the outer of motor
Shell can seal the aperture of powder tank bottom well.It should be noted that avoid remaining experimental provision because of the excitation of motor
And vibrate, it needs that hose is added in the outlet end of the arrival end of air inlet pipe, capillary respectively, air inlet pipe and capillary should all pass through
Hose could be connected with normal pipeline.When the vibration of motor is transferred to hose, the particularity meeting decay amplitude of hose material reaches
To the purpose of buffering vibration, reliability when whole system operation, safety and stability have been ensured.
The effect of above-mentioned powder feeder unit is to extract powder from storage tank, and igniter is supplied to burn.
Igniter is arranged in the outlet end of capillary, is made of ignition wire, pedestal, housing and reaction vessel.There are two being opened in pedestal
Aperture, intermediate aperture can light the powder in reaction vessel for installing ignition wire, ignition wire after being powered；Chassis side it is small
Hole is used to convey the powder flowed out from capillary.Housing is placed on pedestal, and aperture is provided on housing, and powder is from capillary stream
It after out, is transported up by the side opening of pedestal, enters combustion chamber using the aperture on housing.Combustion chamber by housing, pedestal and
Reaction vessel is formed, and combustion reaction carries out here.Spectrometer is arranged near igniter as detection device, and right
The reaction of combustion chamber is detected in igniter.
Air is depressurized through pressure reducer first from high pressure gas cylinder, then respectively through valve, flowmeter, hose and air inlet
Pipe enters powder tank, and since stirring bar follows motor to rotate synchronously, the stirring action of stirring bar can make the powder one in storage tank
It is straight to keep motion state without reuniting.Powder is sent from capillary blowout to igniting and is filled by the air-flow come out from air inlet pipe
In setting.Wherein, due to the buffer function of hose, the vibration of powder tank will not influence the normal work of remaining device.
Powder is from inlet point fire device after capillary outflow, and powder is transported up from the aperture of chassis side, into housing
It is interior, then the combustion chamber as composed by ignition wire, pedestal, housing and reaction vessel is entered by the aperture on housing, by ignition wire
After energization, powder starts to burn.Spectrometer is responsible for detecting combustion reaction.
Beneficial effect
It, can not only using the mixing effect that motor rotates 1. the stirring bar being connected to the motor is protruded into tank inside by the present invention
So that the powder for sinking to tank bottom originally is suspended, prevents from reuniting, powder is made to be easier to be blown out by air, and can dredge in time stifled
The capillary of plug guarantees that powder supplies are continuously smooth.
2. combustion experimental device of the present invention is using hose as intermediate medium, buffer motor brings system its remaining part
The vibration of part guarantees the reliability of system.
3. combustion experimental device structure according to the present invention is simple, at low cost, it is easy to accomplish, it can guarantee efficient, lasting
Ground powder supply.
