Description
Affiliated technical field
The utility model belongs to a kind of material disintegrating apparatus, relate generally to a kind of vertical impact crusher emission impeller with two emission ports, be specially adapted to hard, ultrahard material in the industry processing such as water power, building materials, highway, refractory material, require the product particle shape to be cube, the poor operation in small, broken bits of faller gill shape, and the application of industry such as artificial sand making.
Background technology
In industries such as water power, urban architecture, highway, refractory materials, need a large amount of artificial sand building stones and refractory material.These raw materials not only need certain rigidity, and processing after finished product be cube, faller gill shape content is few.The equipment in small, broken bits that relatively is applicable at present these materials of processing mainly is vertical impact crusher (JB/T7353-94).Vertical impact crusher mainly is made up of emission impeller and whirling motion chamber that level is installed, and impeller rotates at a high speed will treat that broken material quickens, get rid of to around liner plate or backing strap in the whirling motion crusher chamber, bounce-back is returned and the stone collision of getting rid of ejaculation again.The emission impeller is the main components of this disintegrating machine, now used impeller emission port is at 3～12, be illustrated in figure 1 as a kind of following impeller disk 5 of emission impeller of three emission ports, it also has with it to being much of the impeller disk, on the impeller disk 5, be evenly equipped with three gussets 1, the middle part has a cloth cone 2, the last impeller disk is fixed by gusset with the following impeller disk and is formed an impeller, the impeller disk middle part on top is provided with a charging aperture, whole impeller is divided into three outlets by gusset, and the upper and lower lobes wheel disc at the runner place of the outlet of impeller is provided with one deck runner liner plate 3, and a wear body 4 is set on the gusset of exit one side, above-mentioned structure is owing to there are three emission outlets (or more), then remove last, outside the following impeller disk, all the other parts are doubled and redoubled, gusset, consumable accessory quantity is more, the discharging opening that forms is less, easily stops up.The impeller own wt is heavier, and power consumption is big, the expense height
Summary of the invention
The purpose of this utility model provides a kind of emission impeller of vertical impact crusher, makes it have two emission outlets, and is simple in structure, few easy workout part, and it is easy, rapid to change, and material is difficult for stopping up.
The purpose of this utility model can adopt following technical scheme to realize: it has symmetrically arranged two impeller disks up and down, middle part at the last impeller disk is provided with material inlet, the impeller disk middle part of bottom is provided with a cloth cone, the bottom is provided with an axis hole, between the upper and lower impeller disk, be fixed with two gussets, gusset becomes two material outlets with the space segmentation between the upper and lower impeller, one side of material outlet place gusset is provided with wear body, and the impeller disk at upper and lower lobes wheel disc material outlet place is provided with the runner liner plate.
Because vertical impact crusher is to adopt liner plate in material that impeller launches and the whirling motion chamber all around or material lining that bump takes place and fragmentation belongs to the probability fragmentation.As long as the inventory that emission port was launched in the unit interval is identical, then the production capacity of vertical impact crusher is also identical.Be not that emission port is many more, production capacity is big more.And the inventory that the impeller emission port sends:
Q＝ρVω
2R
ρ-material density V-impeller emission port volume sum is V=nV
1V
1-single emission port volume
N-emission port quantity ω-impeller angular velocity of rotation ω=π n/60 R-impeller radius.
Because to same specification vertical impact crusher, ρ, ω, R are definite value, as long as V=nV1 is a definite value, then the inventory sent of impeller emission port also is definite value.V=nV
1In the blade wheel structure design process, be easy to realize by adjusting impeller height or other physical dimension.Therefore, the impeller of two emission ports is with the impeller of three above emission ports, and the inventory of launching in the unit interval is identical, and its production capacity is also identical.
By said structure and principle as can be seen, the utility model is by being made up of the upper and lower impeller disk, two pairs of gussets, two pairs of runner plates, two groups of wear body.Compare with existing three emission port impellers that generally use, gusset consumable accessory quantity all reduces 1/3, and is simple in structure, and the runner mouth of formation is big, and consumable accessory quantity is few, and own wt is light, and the power consumption that works together is little, is difficult for stopping up, and it is few to change consumable accessory quantity, and the time is short.Because single discharging opening enlarges, feed size increases to hard crisp material less than 150mm by being generally less than 50mm, and the toughness rock is less than 80mm.At same specification vertical impact crusher, under the same production capacity, motor power consumption descends 15%～20%, the dust content that gives off descends more than 10%, and the consumable accessory of rotor reduces relatively, and the abrasion expense descends more than 20%, the single discharging opening of impeller is big, be difficult for stopping up, consumable accessory quantity is few, and it is easy, rapid to change.Under identical impeller size and rotating speed, product has identical particle distribution curve.Two emission port impellers replace three above emission port impellers, under same specification equivalent production capacity and like products granularity composition situation, it is big that two emission port vertical impact crushers have a feed size, discharging opening is difficult for stopping up, the consumable accessory expense is low, power consumption is little, effluxes the few characteristics of dust content.
