Description
Technical field
The utility model relates to a kind of rigid impeller feeding machine with roller.
Background technology
Revolving plow reclaimer takes turns feeder, star discharge valve, rotary feeder, electric lock pneumatic device etc. also known as lattice, and it is the one machinery being widely used in carrying powder or granule materials in the industries such as mine, metallurgy, building materials, chemical industry and processing.The structure of revolving plow reclaimer is grouped into primarily of vane rotor (or claiming star rotor), shell, transmission device and motor part.The upper and lower side of shell is provided with material import and export, and the import of upper end is generally be connected with feed bin, and the outlet of lower end can be opened wide and also can be connected with the machinery such as downstream load transfer device as required.Between the blade that during work, material directly falls into box-shrouded impeller rotor from the import of upper end (being commonly called as lattice room), then with blade rotary, fall to exit, lower end material by self gravitation.The rotation of rotor is generally drive with electrical motor, is provided with transmission and speed reduction gearing between rotor and electrical motor.During rotor turns, material flows out, and when rotor does not turn, material can not flow out, and when rotor turns is fast, streams output is large, and when rotor turns is slow, streams output is little, but rotor can not reverse.So revolving plow reclaimer has feed and lock material or locks airway dysfunction, namely has the function of valve concurrently.
Revolving plow reclaimer belongs to low-speed running machinery substantially, and rotating speed is generally no more than 60prm, and mostly at 20prm-30prm, the inventory of process is generally also no more than 100m
3/ h.
The characteristics influence that the mechanical characteristics of revolving plow reclaimer work is subject to processing material is very large, such as, the granularity of material, the cohesiveness of material, hardness of material etc., causes the process of the cisco unity malfunctions such as impeller is stuck, Scale of blade, frequent burning motor to happen occasionally thus.
Summary of the invention
It is few that the purpose of this utility model is to provide a kind of mechanical breakdown, the rigid impeller feeding machine of the band roller that mechanical efficiency is high.
In rotation or rotary machine, between rotor and stator (such as casing), leave gap be inevitable, this is the needs of relative motion.The size in gap or the determination of title fit dimension size have very large relation with processed material.Process powder or granule materials are different from process gas and liquid, because gas and liquid have flowing power and deformability, but to powder or granule materials, although also there is certain flowing power, but the ability of deformability is just much poor, and powder or particulate matter also have moisture knot block and incompressible feature.Like this, the factor of play such as considered in the rotary machine such as centrifugal pump and centrifugal compressor, that will consider in revolving plow reclaimer just may be completely different.
For revolving plow reclaimer, the determination of gap length is not only a mechanical efficiency problem, perhaps prevents the stuck impeller of material to be only the problem of overriding concern.For this reason, the impeller form of revolving plow reclaimer divides again elasticity impeller and rigidity impeller.So-called elasticity impeller refers to that the blade of impeller adopts elastomeric or spring plate system.Blade with turn Grains and tilt backwards an angle along hand of rotation and be fixed on and turn on Grains, between blade and casing, gap can be very little, and the extruding running into material can make blade produce bending backward a little.So-called rigidity impeller refers to the blade of impeller and turns hub and be made into an entirety or casting matrix, and blade is generally all abundant, shows as rigidity, and blade arrangement radially.At first sight, elasticity turbine has little, the telescopic feature in gap concurrently, and seem to be better than rigidity turbine completely, actually this is not so.Elasticity turbine also has the weakness of oneself and limits Applicable scope, and such as, very thin when running into material, cohesiveness is large; Or raw meal particle size and all large occasion of hardness, stuck impeller and cisco unity malfunction also have.Elasticity turbine does not belong to key content of the present invention, therefore does not provide its accompanying drawing at this.
The blade outer rim of rigidity impeller and the gap general control of casing arc surface are at about 2mm.Certainly, require that this gap size also can customized design for different material.But for the intensity of rigidity impeller, blade always has again certain thickness, no matter large or little gap then between blade outer rim and casing arc surface is, relative to the particle ensureing absolute uniform surely that differs, capital more or less forms angle of nip and clamp effect to some particles, particularly when running into hard particulate matter, if when impeller squeese pressure is not enough to pulverizing particulate, the phenomenon of stuck impeller just there occurs.
The utility model is achieved in that it comprises material inlet, wheel shaft, vane rotor, shell, material outlet, it is characterized in that roller is equipped with in each blade outer rim end of vane rotor.
The diameter of roller as above is equal with blade thickness, and the length of roller is less than the width of blade, and the Width along blade is embedded on blade, and roller two ends adopt thimble to fix.The form of thimble is a bearing pin, one crown is lived and is supported roller, one to adopt with blade and is threaded, for preventing the model pine that is threaded of thimble, mosaic holding screw is provided with in the side, threaded connection place of blade and thimble, the center of thimble is provided with when needing with oilway can lubricate, and the end of thimble is provided with hexagon socket head so that mounting or dismounting.
Material inlet as above and material outlet design are also features of this patent design, the position that material inlet is connected with shell is that the intersection point of material inlet madial wall and shell Inner arc turns to right avertence from shell vertical line of centers 13 ° ~ 15 ° along vane rotor, material inlet madial wall and material inlet lateral wall respectively with the point of intersection with shell Inner arc for fulcrum is respectively towards flare Dou, material inlet madial wall and material inlet lateral wall are 15 ° ~ 18 ° with the angle of the point of intersection perpendicular line of shell Inner arc respectively.The intersection point of material outlet madial wall and shell Inner arc departs from shell vertical line of centers 15 ° ~ 18 ° along vane rotor port.
Material import and export size, namely lateral dimension and width dimensions can be determined according to the flow of material handling and flow velocity.
From the motion of band roller vane rotor, then when unloaded blade one forwards this angle to, material is gravity and storehouse material pressure from import to impeller lattice room power, descending material will slip into lattice room along this angle, along with vane rotary, this lattice room is filled up by material, process is entered at material, the material falling into lattice room is subject to the storehouse material pressure on top or the downward application force of gravity one always, impeller vane promotes the power that will apply a circumferencial direction when lattice room material rotationally moves to material, the material of lattice room can be subject to downward with two application forces that are circumferencial direction, but due to feed entrance point on the right side of feeder vertical center line 13 ° ~ 15 °, the down direction of blade or lattice room, the angle tilted makes the suffered and upwards application force of material greatly extenuate downwards, and material gravity and blade tangential forces also can form combined action at hand of rotation, thus the effect not only economizing merit but also reduce express material can be realized.In like manner, deviate from an angle 15 ° ~ 18 ° due to madial wall to a shell vertical center line left side in the outlet of material, material vertically can not be fallen from lattice room, can only slide to be greater than this angle, thus reduce coupled below machinery impact.Also have a benefit to be exactly that the material that can promote feeder blocks gas ability to vertical center line left avertence from an angle.
Can freely rotate with roller turbine roller relative vane while blade rotation, when running into the gap that particle object appears between blade outer rim and shell arc surface, application force a little just can make roller rotate, and realizes dodging, thus avoids whole impeller to be stuck.Blade with roller turbine also has a function to be exactly when it is through the arc surface at material inlet place, with the cutting of the form of friction of rolling with through the bed of material because roller can rotate, do not have the blade of roller to be then with the cutting of the form of cliding friction and pass the bed of material, the arc length at material inlet place occupies suitable high range whole depositing in material shell arc length, and friction of rolling is just little relative to the power of the little consumption of contact surface cliding friction.
The utility model has the following advantages with there being tool compared with technology:
1. consumed power reduces, the corresponding reduction of power of motor;
2. can realize dodging, can avoid material that whole impeller is stuck;
3., because discharging opening and vertical center line deviate from an angle, the impact to upstream device can be effectively reduced;
4. charging and discharging mouth is not on vertical center line, can further improve dense block gas performance.
