Description
Technical field
The utility model relates to a kind of coal screening feed hopper, particularly relates to a kind of colliery even distribution type and enters to sieve coal supply buffering hopper.
Background technology
Coal mine separation vibratory sieve is mainly used to the different coal cinder of sorting granule size, and the effect of its screening is relevant in the distribution of compass screen surface with coal cinder.Coal cinder is good at the compass screen surface then screening effect that is evenly distributed, otherwise screening effect is just poor.Coal cinder to flow into coal in compass screen surface distribution and sieve orientation and have relation, and coal stream just enters to sieve to compass screen surface, then coal stream easily scatters, and greatly, screening effect is good, also little to the impulsive force of sieve plate for distribution area.Coal stream enters sieve from side, then easy in the longitudinally one-tenth line style accumulation of compass screen surface coal dropping point, at compass screen surface skewness, screening effect is poor, to large, the fragile sieve plate of sieve plate impact forces.
Utility model content
The purpose of this utility model to provide a kind of colliery even distribution type to enter to sieve coal supply buffering hopper, no matter make to screen coal to flow can make coal cinder be evenly distributed at compass screen surface after which angle enters hopper, solve coal stream screening effect poor, compass screen surface is impacted large, the flimsy problem of sieve plate.
The purpose of this utility model is achieved in that this hopper comprises: blow tank, adjustable spillplate, changed course coal guide plate, jack, guiding hopper, coal guide plate, triangular guide rail, all distributing trough, hinged seat, adjustable buffer board, first leads coal track, buffering fixed head, second leads coal track, external jack and buffering lattice plate; Blow tank, guiding hopper are linked in sequence into hopper from top to bottom with equal distributing trough, corresponding adpting flange is all had in the junction of each hopper, adjustable spillplate and changed course coal guide plate is welded with in blow tank, changed course coal guide plate is fixedly welded on blow tank, adjustable spillplate one end is hinged on blow tank, the other end is fixed by jack and blow tank, can rotate under the drive of jack, changes gear coal angle; Guiding hopper right flank is coal guide plate, coal guide plate is welded with the triangular guide rail in fan-shaped layout; Be welded with hinged seat in equal distributing trough, adjustable buffer board one end is connected with hinged seat, adjustable buffer board is welded with first and leads coal track, and the adjustable buffer board other end is connected with external jack, and adjustable buffer board is adjustable angle under external jack effect; Also be welded with buffering fixed head in equal distributing trough, buffering fixed head is welded with second and leads coal track; Buffering lattice plate is in the lower end of equal distributing trough, and side iron chains is fastened on equal distributing trough, and the other end is placed on oscillating screen, layout of freely dangling in incline direction.
Beneficial effect, the geometry of hopper and internal structure for the desirable guide mode of guarantee and working condition extremely important.Owing to have employed such scheme, the coal stream shipped from raw coal belt is injected in blow tank with certain speed, adjustable spillplate and changed course coal guide plate is welded with in blow tank, under the stop and the guide effect of changed course coal guide plate of adjustable spillplate, coal stream deflection hopper side slips down in next stage deflector chute.Adjustable spillplate, changed course coal guide plate and blow tank surrounding side plate use manganese steel plate make, resist pound wear-resisting.Changed course coal guide plate is fixedly welded on blow tank; adjustable spillplate one end is hinged on blow tank; the other end is fixed by jack and blow tank; can rotate under the drive of jack; coal stream angle is stopped to change it; being convenient to coal stream imports simultaneously to the deceleration of coal stream in next stage guiding hopper smoothly, protection next stage hopper.After flowing to guiding hopper from upper level blow tank coal out, first coal stream impact on the coal guide plate on the guiding hopper right side, coal guide plate is number manganese steel plate that 30mm is thick, it is welded with the triangular guide rail in fan-shaped layout, triangular guide rail surface inserting has to resist pounds wear-resisting high-molecular polythene wear-resistant plate.Coal stream glides along triangular guide rail, slows down and progressively increases discharging area, finally skidding off guiding hopper, enter in equal distributing trough.Triangular guide rail is sharp Mitsubishi cone, is convenient to coal downslide dispersion.Flow in equal distributing trough from guiding hopper coal out, first coal stream slows down after penetrating and touching adjustable buffer board, and coal track downslide increase coal is wandering opens area to force coal stream to be led along first of welding on it, the coal stream scattered subsequently, again penetrate after touching buffering fixed head and slow down again, lead coal track along second to glide and the area that scatters increasing coal stream further, last coal stream skids off from equal distributing trough with low speed uniformly, injects on buffering lattice plate.Adjustable buffer board is adjustable angle under external jack effect, to control coal flow path direction and to protect adjustable buffer board, prevents from being pounded.Directly change after adjustable buffer board wearing and tearing.Buffering lattice plate is a monoblock 2000mm*1500mm, and thickness is that the 16# manganese steel plate of 16mm makes.Dig out 8,18*18mm hole, 16, surrounding 16*16 hole in the middle of buffering lattice plate, specification is slightly larger than the hole 15*15 of sieve plate, and each angle of spot hole arc chord angle of falling 30mm, upside chain link is fastened on equal distributing trough, and lower end is placed on compass screen surface freely.Play anti-directly impact sieve plate and guide the effect of coal stream, sieve plate face is directly smashed for preventing the bulk in coal stream, and main coal stream is imported on rear sieve plate of integration type face smoothly, ensure to need the fraction coal of screening draining on lower floor's compass screen surface by also can directly screen during these lattice plate simultaneously.
Advantage: hopper each other opening is large, and adjustable by jack, can avoid bulk coal, spoil blocking, bridging, inaccessible material mouth.Coal stream can be forced to alter course continuously in groove, and feed is comparatively loose, and continuously, compass screen surface is evenly distributed, exit point is accurate, is convenient to screening.Structure is simple, realizes sealing feed, not airborne dust, and reliable operation, use are extensively.
