Description
Technical field
The invention belongs to the technical fields of the production equipment of bio-fuel, specifically disclose a kind of bio-fuel particle screening
Device.
Background technology
Bio-fuel refers to regarding biological material burning as fuel, and generally mainly agriculture and forestry organic waste material, such as stalk are sawed
End, bagasse, rice chaff etc. are a kind of a kind of Novel clean-fuels that can directly burn.Its manufacturing process is by crushing, mixing
The techniques such as conjunction, extruding, drying, are made various moldings, China is generally formed into the cylinder of strip by above-mentioned waste.
Currently, the comminutor of the bio-fuel in China is all be made into strip cylindric mostly, cylinder is called in the following text
Grain, but can have a large amount of bio-fuel powder, spheric granules or impurity during manufacture, it needs these powder
End, circular granular and impurity all screen.In the prior art, be mostly using sieve come by cylindrical particles powder,
What circular granular and impurity screened out, but if cylindrical particles when sieving powder just at vertical state, cylindrical particles
It can cause partial cylinder particle that can be sifted out by sieve.
Invention content
The purpose of the present invention is to provide a kind of bio-fuel particle screening devices, to solve to have powder in bio-fuel particle
The problem of end, circular granular and impurity.
In order to achieve the above object, base case of the invention is:Bio-fuel particle screening device, including rack, leakage
Bucket and the first slideway, the funnel and first slideway be arranged in rack, one end of the first slideway be connected to funnel and
First slideway is downwardly inclined, and the lower part of the funnel is in cuboid, and several guide cylinders, institute are in a row equipped with vertically in lower portion
It states and is equipped with several sliding slots in the first slideway along its length, the sliding slot is in semi-cylindrical, and sliding slot is located at the lower section of guide cylinder;Machine
The second slideway is also provided tiltedly on frame, the angle of inclination of second slideway is identical as the first slideway, and the second slideway and first is slided
There are gap between road, the length in the gap is less than the length of bio-fuel particle;Second slideway is equipped with several groups
Motivation structure, the toggle mechanism include the cavity being arranged on the second slideway close to the end of the first slideway, are equipped with and turn round in cavity
Spring is equipped with turntable on torsional spring with one heart, and the upper end of turntable is hinged with bullet block, and one end of bullet block extends to outside the side wall of the second slideway,
The lower end of turntable is hinged with the first pushing plate, and one end in the first pushing plate close to the first slideway is hinged with the second pushing plate, the
The middle part of two pushing plates rotates in rack and is obliquely installed, and the inclined direction of the second pushing plate is identical as the second slideway and it inclines
Rake angle is more than the second slideway, and the second pushing plate offsets close to one end of the first slideway and the end of the first slideway.
The operation principle of this base case is:Cylindrical particles to be sieved are poured into funnel, cylindrical particles are from funnel
In enter guide cylinder, since guide cylinder is vertically arranged, thus after cylindrical particles enter guide cylinder its direction straight down, by
It is located at the lower end of guide cylinder in sliding slot, so cylindrical particles can be fallen directly into sliding slot and slide downward.When spheric granules, powder
Its movement locus is parabola after end or impurity are detached from the first slideway, and can be directly fallen in the second pushing plate, and from second
It is slipped to the first pushing plate in pushing plate, is finally dropped out from the first pushing plate.When cylindrical particles will be disengaged from the first slideway, i.e.,
When the center of gravity of cylindrical particles is located at outside the first slideway, since its length is longer, so only most cylindrical particles are detached from the
When one slideway, cylindrical particles can just tilt down, and when it is tilted down, the lower end of cylindrical particles can touch bullet block and will
Bullet block inwardly pushes a distance, bullet block that turn disc, rotating disc can be driven to drive the first pushing plate to the first slideway again
Direction is moved, and the second pushing plate pushes the lower end of the first pushing plate again, due to being rotatably connected on rack in the middle part of the first pushing plate
On, so the upper end of the first pushing plate can make the movement of arc to the direction of the second slideway and dial up cylindrical particles, make
Cylindrical particles can enter in the second slideway.
The advantageous effect of this base case is:In the present solution, when spheric granules, powder and impurity are skidded off from the second slideway
After can directly fall in the second pushing plate, and cylindrical particles can be fallen in the first slideway under the stirring of the second pushing plate from
It is dropped out in one slideway, realizes the screening of cylindrical particles, and be not in problems of the prior art.Meanwhile this programme
In, cylindrical particles are after guide cylinder and sliding slot, straight uniform of arranging, convenient for collecting bag-in-container.
Further, further include acceleration mechanism, the acceleration mechanism includes motor and accelerating pulley, and the motor is arranged in rack
On, accelerating pulley is arranged on the output end of motor, and the lower sides of the funnel are equipped with opening, and the side wall of accelerating pulley is extend into
In opening.Using this programme, accelerating pulley is extend into the opening of side wall, so accelerating pulley can contact with cylindrical particles and make circle
Column Particle Acceleration moves downward.
Further, the side wall on the funnel top is elastic wall, is additionally provided with cam on the motor, drawing is hinged on cam
Bar, it is hinged with elastic wall close to one end of elastic wall on pull rod.Motor band moving cam rotates, and cam driven pull rod moves back and forth,
Pull rod drives elastic wall to move back and forth.When a large amount of cylindrical particles pour into funnel, cylindrical particles may be blocked in guiding
On cylinder, and this programme is used, elastic wall continual reciprocation can constantly move the cylindrical particles in funnel, prevent it stifled
Plug, while can also improve screening efficiency.
Further, bristle is equipped in the guide cylinder.Using this programme, when cylindrical particles pass through guide cylinder, bristle energy
Under enough dusts or powder brush by cylindrical particles.
Further, 1-2 times of the diameter of the guide cylinder equal to bio-fuel particle diameter.Using this programme, guide cylinder
In can accommodate a cylindrical particles, also have enough spaces that spheric granules, powder etc. is made to fall.
Further, the lower end of second slideway is equipped with collecting box, and the lower end of the first pushing plate is equipped with slag case.Collecting box is used
In collecting cylindrical particles, slag case is for collecting spheric granules, powder etc..
