Background technology
At present, the combustion systems of powders (being powdered fuel) such as use coal dust, petroleum coke powder as comburant appearred.In this system, the conveying that powder is carried stabilizing device through powder, burn in the combustion zone that arrives powder.Wherein, powder carries stabilizing device to comprise inlet point, and inlet point is connected with powder delivering pipe, is provided with spiral feeder in the powder delivering pipe, and spiral feeder is connected with engine installation.Like this, engine installation drives spiral feeder and rotates, and will get into carrying of powder extruding in the powder delivering pipe by inlet point.Its defective is: 1, carry powder stable inadequately, and 2, scurry wind easily when utilizing strength to carry powder and leak.Therefore be necessary to improve.
Summary of the invention
To the deficiency that above-mentioned prior art exists, the purpose of this invention is to provide a kind of powder and carry stabilizing device, it has carries powder steadily and no leak, do not have the characteristics of scurrying wind.
To achieve these goals; The technical scheme that the present invention adopted is: powder is carried stabilizing device, comprises inlet point, and inlet point is connected with powder delivering pipe; Be provided with spiral feeder in the powder delivering pipe; Spiral feeder is connected with engine installation, and the pitch of the helicallobe on the left of being positioned on the said spiral feeder is greater than the pitch of the helicallobe that is positioned at the right side, and the junction of spiral feeder and engine installation is provided with the sealing device for preventing leakage.
Said sealing device for preventing leakage comprises the labyrinth type grease.
Said sealing device for preventing leakage comprises the oil immersion packing.
Said powder delivering pipe right side is connected with fluidising chamber, and fluidising chamber is connected with high-pressure air hose and high velocity stream is penetrated pipe, and high-pressure air hose and high velocity stream penetrate the pipe junction and be provided with blending bin, and this blending bin and powder delivering pipe exit match.
The exit of said powder delivering pipe is provided with airlock.
Said airlock comprises the lock windshield plate, and this lock windshield plate is hinged in the exit of powder delivering pipe, and the lock windshield plate is connected with stage clip.
Said stage clip is furnished with pressure-regulating device.
After adopting said structure, the present invention compares the advantage that is had with prior art and is: 1, carry powder steady, form the material envelope, no leak.Powder of the present invention carries the pitch of stabilizing device through making spiral feeder by diminishing greatly gradually, and the delivery pressure that powder receives increases gradually, thereby powder progressively compresses and forms fine and close material seal, and then it is comparatively steady that powder is carried.Be provided with the sealing device for preventing leakage in the junction of spiral feeder and engine installation, avoided powder to reveal and air leakage phenomena effectively.After the optimization, use labyrinth type grease and oil immersion packing and sealing gland as the sealing device for preventing leakage, then sealing effectiveness is better.2, powder is carried smooth and easy.Powder mixes with high-pressure blast in fluidising chamber, thereby gets into high velocity stream when penetrating in the pipe, and powder has high flow velocity and pressure.That is powder carried out fluidization treatment, thus the conveying of powder has possessed the flowing power as liquid is carried, and then carry smooth and easyly, be difficult for blocking pipe.3, promote the powder economic combustion.Powder of the present invention after the acceleration of high-pressure blast and pressurization, the raising that the powder flowing power obtains, and air quantity, blast are constant, thus after getting into the combustion zone, have degree of dispersion and degree of uniformity preferably, and then combustion performance is improved.

Among the figure: 1, inlet point; 2, powder delivering pipe; 3, spiral feeder; 4, sealing device for preventing leakage, 41, the labyrinth type grease, 42, the oil immersion packing; 5, engine installation; 6, fluidising chamber; 7, blending bin; 8, high-pressure air hose; 9, high velocity stream is penetrated pipe; 10, airlock, 101, the lock windshield plate, 102, stage clip, 103, pressure-regulating device.
The specific embodiment
The following stated is merely preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
Embodiment, see illustrated in figures 1 and 2: powder is carried stabilizing device, comprises inlet point 1.Inlet point 1 is connected with powder delivering pipe 2, is provided with spiral feeder 3 in the powder delivering pipe 2, and spiral feeder 3 is connected with engine installation 5.Engine installation 5 can be motor and auxiliary facility thereof.Obviously, spiral feeder 3 is provided with helicallobe.Like this, through the drive of engine installation 5, the helicallobe rotation drives powder and in powder delivering pipe 2, carries from left to right.The pitch of helicallobe that is positioned at the left side on the spiral feeder 3 is greater than the pitch of the helicallobe that is positioned at the right side, i.e. variable pitch structure, and along the throughput direction of powder, pitch reduces gradually.Like this, impel helicallobe that powder is pressurizeed gradually, powder is progressively compressed form fine and close material seal, and then it is comparatively steady that powder is carried, prevent to leak out and scurry the wind phenomenon.For fear of the leakage of powder, the junction of spiral feeder 3 and engine installation 5 is provided with sealing device for preventing leakage 4.Optimize, sealing device for preventing leakage 4 comprises labyrinth type grease 41, also can include oil immersion packing 42 and air seal structure etc. simultaneously.
See shown in Figure 3ly, in order further to increase the flowing power of powder, powder delivering pipe 2 is connected with fluidising chamber 6.Fluidising chamber 6 is connected with high-pressure air hose 8 and penetrates pipe 9 with high velocity stream, and high-pressure air hose 8 penetrates pipe 9 junctions with high velocity stream and be provided with blending bin 7, and this blending bin 7 matches with powder delivering pipe 2 exits.That is, powder flow to blending bin 7 from powder delivering pipe 2, is pressurizeed by the high pressure in the high-pressure air hose 8, high speed winds at blending bin 7 places afterwards, and the powder that then has elevated pressures and speed gets into high velocity stream and penetrates pipe 9.Like this, powder is carried out the height fluidization treatment, made it to have possessed extraordinary flowing power.Force powder to flow backward in the powder delivering pipe 2 for fear of high-pressure blast, the exit of powder delivering pipe 2 is provided with airlock 10.Like this, airlock 10 further forces the exit of powder delivering pipe 2 to form the material seal of certain density.Airlock 10 can be taked multiple modes such as electron steering, optimization, airlock 10 comprises lock windshield plate 101, this lock windshield plate 101 is hinged in the exit of powder delivering pipe 2, and lock windshield plate 101 is connected with stage clip 102.Like this, lock windshield plate 101 presses powder under the compressing of stage clip 102, thereby avoids high-pressure blast compressing the powder here to form refluence and scurry wind.Further, stage clip 102 is furnished with pressure-regulating device 103.This pressure-regulating device 103 can be adjustable column, regulate bolt etc., is used to regulate the initial pressure of stage clip 102.
