The filter device has the advantages that all points are stressed evenly, and no dead angles exist in the use process of the screen plates; the effect of intermittently and periodically removing blocking of the screen plates is achieved through the simple ratchet wheel and ratchet mechanism; materials flow out more easily on the basis of the resonance principle.
Description
Technical field
The utility model relates to a kind of filter of pebble coal box, relates in particular to a kind of stone coal bin screen cloth filter.
Background technology
Pebble coal is the pyrite not being grated and the spoil of being carried secretly and the coal grain that coal pulverizer is discharged from bottom in running.Because its impurity content is many, pebble coal, before entering next step operation or using, needs removal of impurities, that is to say and need filter, the filter of present stage is to utilize pebble coal box mostly, and the structure of pebble coal box is a truncated rectangular pyramids taper hollow shell, this housing top is provided with feeding mouth, bottom is discharging opening, is provided with the sieve plate of filtration in box, and pebble coal is from feeding mouth enters, through sieve plate, impurity is retained on sieve plate, and pebble coal flows out from discharging opening, completes the process of filtration.This technology in use, often, because the size of the hollow out of sieve plate is too small with respect to impurity, causes the obstruction of sieve plate through hole, affects follow-up filter effect.And due to the compact conformation of this casing own, inside is not suitable for installing and makes its vibratory equipment significantly sieving, the problem that sieve plate stops up is difficult to solve.
In Chinese patent literature CN200380096U, announced a kind of stone coal bin filter, its technical scheme is mainly to have increased knocking device on the sieve plate of pebble coal, and timing is beaten sieve plate, prevents hollow out obstruction, improves filter effect.But its weak point is, reciprocal beaing the damage of sieve plate is large, affects the service life of sieve plate, increases production cost.
Summary of the invention
The utility model is intended to solve the filtration of pebble coal box in prior art and easily stops up, and after beaing, affects sieve plate service life, the problem that production cost is high.A kind of stone coal bin screen cloth filter is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
Stone coal bin screen cloth filter of the present utility model, the top of sieve plate in stone coal bin, described filter comprises ratchet ratch mechanism, is arranged on the vibrator bar on ratchet ratch mechanism ratchet and is arranged on the block on sieve plate, and the distance that is arranged on the above ratchet center of described sieve plate and block with the axle coordinating of described ratchet is less than the distance of described ratchet center and vibrator bar end.
As preferred embodiment, described vibrator bar is arc.
As preferred embodiment, described baffle plate is distributed in sieve plate surrounding.
As preferred embodiment, described vibrator bar (2) be the vibrations bar that 65Mn makes.
As preferred embodiment, described sieve plate is the reinforcing bar being crisscross arranged, and the two ends of this reinforcing bar are placed in the groove corresponding with its shape of described stone coal bin edge setting.
As another embodiment, described ratchet ratch mechanism replaces with the stepper motor of circuit control, and described vibrator bar is connected with motor output shaft.
The beneficial effects of the utility model show as:
(1) each point is stressed evenly, and sieve plate uses without dead angle;
(2) utilize simple ratchet ratch mechanism to realize the obstruction effect of the eliminating sieve plate at periodic intermittence, time saving and energy saving;
(3) utilize resonance principle that material is more easily flowed out.

Detailed description of the invention
Embodiment 1
The stone coal bin screen cloth of the present embodiment is shown in Fig. 1 to Fig. 2 with filter, the top of sieve plate in stone coal bin, described filter comprises ratchet ratch mechanism, is arranged on the vibrator bar 2 on ratchet ratch mechanism ratchet and is arranged on the block 1 on sieve plate 7, and the distance that is arranged on the above ratchet center of described sieve plate and block 1 with the axle coordinating of described ratchet 3 is less than the distance of described ratchet 3 centers and vibrator bar 2 ends.
Described vibrator bar 2 is arc, and the material of vibrator bar is 65Mn.Described baffle plate 1 is distributed in sieve plate 7 surroundings.
The reinforcing bar of described sieve plate 7 for being crisscross arranged, the two ends of this reinforcing bar are placed in the groove corresponding with its shape of described stone coal bin edge setting.
As general knowledge as well known to those skilled in the art, the ratchet outer cover of ratchet ratch mechanism is equipped with spring and is used for locating and resetting.
In use procedure, to ratchet 5 to the stone coal bin internal direction application of force.Ratchet 5 drives ratchet 3 to rotate, and in the time that external force disappears, spring drives ratchet 5 returns, realize the intermittent rotary of ratchet 3, in each rotation of ratchet 3, drive vibrator bar 2 to rotate, 2 of vibrator bars are as circularoscillations bar, in the process of rotating, material is played to the effect of leading and advancing, meanwhile, the edge of vibrator bar 2 bumps with baffle plate 1 in the process of rotating, in collision, drive sieve plate 7 to vibrate, this vibration causes material can on sieve plate 7, not stop up.
The vibration of cyclical intermission has ensured to realize vibrating function and crushing function, can also have the independently process of material process.Vibration that can be not simply and affect the performance level of screening process.
The reinforcing bar of sieve plate 7 for being crisscross arranged, and the edge of two ends fixed word stone coal bin has ensured the adjustable of 7 spacing of sieve plate, when requiring when high, sieve plate 7 spacing are little, in the time that screening is less demanding, the spacing that sieve plate is 7 is large, simultaneously, the design of adjustable interval has reduced the installation difficulty of ratchet ratchet means on sieve plate 7, when installation, installs by installing component 6.
The material of vibrator bar 2 is 65Mn.Namely conventional spring steel, what object was to ensure vibrator bar 2 can resilience, and vibration in springback process, and vibrator bar 2 completes the application of force to stone coal charge in the process of vibration, prevents from stopping up.Baffle plate 1 is arranged at the surrounding of sieve plate, and object is the equilibrium that ensures the surrounding application of force, makes blanking without dead angle.
In process of production, the effect that prevents that sieve plate from stopping up has been played in the vibration of vibrator bar 2 incessantly, has also played to a certain extent the effect that bulky grain is smashed by vibration.Thereby the output capacity of the finished product further improving.
In Fig. 1,6 is installing component, has specifically played the effect of fixed ratchet wheel ratchet on sieve plate.
