Abstract
A chute with a block coal anti-broken device is characterized in that the chute is provided with a block coal anti-broken device using a rubber roller. The device mainly includes a rubber roller and a supporting driver shaft, the walls of the sides of the chute are provided with runners, and the supporting driver shaft is penetrated into the runner. The block coals slow down quickly because of the collision with the rubber roller when the block coals slip. The successive block coals slipping from the upper portion squeeze the subjacent block coals, and the rubber roller is jacked up by the subjacent block coals which get across the rubber roller. In this way, the impact of the block coal to the wall of the chute and the loss of the block coal are reduced, and the economic benefits and the income are increased.
Description
One, technical field
The utility model relates to a kind of coal preparation plant has anti-lump coal breaking when carrying lump coal chute.
Two, background technology
At present, in coal production, the course of processing, lump coal is the very wide and price high product of a kind of use, and therefore, improve lump coal rate is the target of pursuing all the time in the coal separation process always.In lump coal conveying, the transfer process, lump coal is because inertia or self gravitation, the speed that falls is very fast, when lump coal falls in chute or during change of direction, the lump coal that rapidly slides will impinge upon at the bottom of the inwall or storehouse of chute with very big momentum, the lump coal that is clashed into will be cracked, damaged, and lump coal rate will reduce.
Three, summary of the invention
The purpose of this utility model provides a kind of chute that has anti-lump coal breaking device, to reduce the fragmentation of lump coal in transportation, reprinting process, improves lump coal rate.
Technical solution adopted in the utility model is: be provided with the stagnant stop block coal anti-crushing device of a rubber rollers on chute, it mainly is made up of rubber rollers and support turning cylinder, correspondence is provided with two perpendicular chutes on the chute two side, and the axial length of rubber rollers is slightly less than the width of chute.
The utility model good effect is: simple in structure, can effectively slow down lump coal with speed before obstacle clashes into mutually, reduce the momentum of lump coal bump obstacle, reduce the lump coal loss, increase economic efficiency, increase income.
Four, description of drawings
Accompanying drawing is a running condition scheme drawing of the present utility model.
Five, the specific embodiment
As shown in drawings, chute of the present utility model is the chute that has anti-lump coal breaking device, promptly on chute 1, be provided with the stagnant stop block coal anti-crushing device of a rubber rollers, this device mainly is made up of rubber rollers 3 and two end supports turning cylinder 6, correspondence is provided with two vertical chutes 5 on the chute two side, the support turning cylinder 6 at rubber rollers 3 two ends penetrates respectively in two chutes 6, and the axial length of rubber rollers 3 is slightly less than the width of chute 1.
Rubber rollers 3 preferably is located at the end of chute 1 in the utility model, during installation chute of the present utility model had anti-lump coal breaking device, an end that promptly has rubber rollers 3 is installed in the bottom of this section chute, that is to say and be installed in before the change of direction, as shown in drawings, or be installed in and connect before next equipment.
At a high speed the lump coal 2 that glides enters when gliding the bottom behind the chute 1, lump coal 2 is subjected to being located at the stagnant resistance of the rubber rollers 3 in the chute 1, after the lump coal 2 that glides impinges upon on the rubber rollers 3 at a high speed, because of rubber rollers has elasticity, so lump coal 2 is subjected to very little momentum effect, and descending speed descends suddenly, the extruding of lump coal above relying on, following lump coal jack-up rubber rollers 3, and from rubber rollers 3 below by, lump coal 2 after the deceleration is when arriving the hypomere chute of change of direction, even run into the sidewall of hypomere chute 4 again, because the speed of lump coal 2 has dropped to very low, until arriving zero, move ahead by wriggling, therefore be subjected to very little momentum, thereby play the purpose that prevents lump coal breaking.
