Description
Technical field
This utility model belongs to Work machine, is specifically related to dissipate material separating sieve.
Background technology
The scattered material screening such as existing coal, when the raw coal that screening moisture, content of ashes do not exceed standard, generally can be normal
Run, complete sizing operation.But in current China, because of the shadow such as human factors of raw ore quality, exploitation and the process of circulation
Ringing, arrive at the raw coal of user, mostly being aqueous colm many, that ash is big has become undisputable fact.This kind is used for a large amount of
The thermal power plant of raw coal, hence it is evident that add the intractability into fired fuel.Outstanding behaviours is in link of screening coal, and stifled sieve phenomenon is generally deposited
, cause coal screen to be not normally functioning and even pause, affect power plant's integral production efficiency.Although person skilled in art was once
Propose the corrective measure of different angles, different modes, but have no the feasible technical scheme that can thoroughly solve problem.
Utility model content
The purpose of this utility model is to provide a kind of bar mesh screen face coal screen having material toggling to comb, for scattered materials such as coals
Screening, it is achieved High water cut, high ash dispersed material sieve the most thoroughly, overcome and sieve common High water cut, high-ash raw coal in China
There is no the present situation of corresponding screening machine.
Technical scheme one
A kind of bar mesh screen face coal screen having material toggling to comb, including complete machine frame, imports the material bin of sieve nest, relatively by supplied materials
The plane sieve nest that ground inclination is installed, the sieve nest reciprocating swing driving means being made up of motor, reducing gear, driving member,
Sieve and the most thoroughly sieve material downstream equipment grass-hopper thoroughly, improvements introduced is: the screen cloth in sieve nest is by parallel by setting spacing
The grating of arrangement is constituted, and forms strip-type screen mesh between grating, and grating intersects with stream direction or be arranged in parallel, below screen cloth
Having by comb and multiple comb are fixed sieve screen apertures material toggling comb (anti-blocking comb) that comb seat (comb back) in a row forms, material toggling is combed
Comb seat arranged in a crossed manner with grating, material toggling comb comb extend upwardly in corresponding sieve screen apertures, in screen frame and comb seat institute
Having, in the frame of position, place, the two groups of slideways being parallel to each other, screen frame and comb seat are separately mounted on two groups of slideways, in frame
The drive mechanism driving sieve nest and material toggling to comb mutually opposing motion is installed.
Technical scheme two:
A kind of bar mesh screen face coal screen having material toggling to comb, transports including complete machine frame, rack-mounted sieve nest and sieve nest
Dynamic drive mechanism, improvements introduced is: sieve nest by screen frame, be fixed on grating arranged in parallel on screen frame, sieve at grating two ends
The side material retaining net erect on body or side block flitch are constituted, and form strip-type screen mesh between grating, and sieve nest is by grating direction
The wheel of rolling, the track of rack-mounted constraint wheel, or directly carry sieve nest by arranging along grating direction
Slideway, or be arranged on as interface components by being arranged in frame the one group of suspending rod swung along grating direction or support bar
In frame, the grating of the sieve nest in frame intersects with stream direction, and charging (supplied materials) end of sieve nest is held higher than discharge (discharging)；
By by comb with multiple comb to be secure rows of at the sieve screen apertures that toothholder forms material toggling comb, material toggling below sieve nest
The comb seat of comb is arranged in a crossed manner with grating, and the comb of material toggling comb extends upwardly in corresponding sieve screen apertures, and material toggling comb passes through support
It is fixedly mounted in frame；
Described sieve nest drive mechanism by rack-mounted motor, reductor, be arranged on speed reducer output shaft
Crank or wheel, crank or wheel and sieve nest between drive sieve nest to form along the reciprocating connecting rod in grating direction, or be arranged on
Between frame and sieve nest drive sieve nest along grating direction reciprocating telescopic hydraulic drive mechanism, or be arranged on frame with
Between sieve nest drive sieve nest along grating direction reciprocating flexible pneumatic drive mechanism.
For making compass screen surface have bigger bearing capacity and reach the optimum efficiency that gravity sieves thoroughly, grating therein selects lamellar bar,
Lamellar grating width face is at vertical direction.
For preventing grating from significantly bending occurring when load, set up parallel with grating between the screen frame at grating two ends
Screen frame fixes the central sill of the grating of several support.
For avoid central sill to comb formed moving disorder and reduce comb shift motion with compact frame, at a sieve nest
Lower waving direction along sieve nest and arrange multiple rows of comb, the comb seat of each row's comb of portable material toggling comb is fixed on same combo box
On, combo box is arranged on slideway and connects drive mechanism.
For obtaining the screening machine of high yield, same portion screening machine sets stepped linking arrangement multiple sieve nests and with
Many groups material toggling comb that each sieve nest coordinates.
For preventing material from forming local stoppages at central sill, each section of central sill between adjacent grating is installed with central sill it is
The sagging rotational swing rod of axle, it is clipped between grating anti-jamming mechanism at the central sill that the pendulum rotating tooth with fork disjunctor is constituted, central sill
Place's anti-jamming mechanism is with being adjacent on comb the top rod driving pointing to fork arranged.
For preventing the fines fallen from screen cloth to be detained formation blocking between comb, then affect follow-up fines and thoroughly sieve,
Reduce the work efficiency of screening machine.Be fixed with corresponding each comb gap on the downside of grating, length is slightly less than comb, stretch to lower section
Comb gap cleaning plate, material toggling comb and sieve nest swing time, cleaning plate can enter or reciprocate through the gap of adjacent fingers.
For promoting the material in grating gap (sieve screen apertures) descending, the crown position of comb has in two sides of moving direction
Inclined-plane towards side-lower.
Described thoroughly sieves and the most thoroughly sieves material downstream equipment grass-hopper usually belt feeder or transfer trolley.
Good effect of the present utility model is: designed and mutual position at component with strip-type screen mesh by material toggling comb
Put, the cooperation of movement relation, it is achieved that the mutual cleaning in work, have and moment is arrested in the material of sieve screen apertures forces to dial and remove
Function, the screening of coal is not affected by ature of coal, eliminates aqueous many, probability that ash is big, viscosity is high colm blocks up sieve,
No longer there is the phenomenon of the conventional stifled sieve as normality, solve the technical barrier of long-standing problem domestic thermal power plant.Meanwhile, phase is completed
Can also reduce, than existing screening machine, the energy consumption that half is many with the screening of quantity colm.
