Abstract
The key of a wearable chute lies in that a guard is provided in the foot of the chute and the inner walls of the two sides of the chute. So at the time of transporting materials the early passed materials will be hindered by the inner guard of the chute, and accumulate between the guards. Following the increase of the passed materials, the materials between the guards will be more and thicker, and a material wearable layer basing on the guards forms gradually. The followed materials will contact with the wearable layer, but not scuff the inner wall of the chute directly, thereby achieving the wearable purpose. The chute of the utility model which is simple in structure and easily produced can effectively prolong the service life of the chute and save the costs of the material and the maintenance.
Description
One, technical field
The utility model relates to the chute of a kind of industrial and mining enterprises widespread usage convey materials.
Two, background technology
At present, industrial and mining enterprises such as coal preparation plant propose from mine from raw coal, through series of process flow processs such as fragmentation, screening, jigging, flotation, filtration, press filtrations, divided the products such as hand picked refuse, lump coal, last raw coal, fine cleaned coal, washing cash, last cash, black water of hanking, these finished products or half-blank carry, in the transfer process, because of constituent, density, and the difference of hardness, very severe to the chute wearing and tearing of carrying them, interior diabase lining, though wear-resisting, to collide frangiblely, maintenance cost is very high.Though abrasion resistance materials such as the rare earth of employing or wear-resisting sand are also arranged,, fail generally to use because cost is too high.
Three, summary of the invention
The purpose of this utility model is a kind of novel wear resistant chute of design, to overcome the deficiency that prior art exists.
Implementation procedure of the present utility model is such: bottom and both sides inwall at chute evenly are provided with little block.Block can be herringbone or rhombus according to the object flow direction and be distributed in chute bottom and chute both sides inwall; With respect to the bigger material of particle, block density is can design-calculated smaller slightly, and with respect to the less material of particle, block density is can design-calculated big.
Good effect of the present utility model is: simple in structure, easy to manufacture, can effectively prolong life-span that is to use of chute, and saved material cost and maintenance cost simultaneously again.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the cross sectional drawing of the utility model under running condition
Five, the specific embodiment
As shown in Figure 1, in chute 2 of the present utility model, be provided with circular and chevron pointing block 3, chute 2 is when carrying washing cash or last cash like this, washing cash that flows through at first or last cash will be subjected to the obstruction of chute 2 internal stops 3, and between block 3, pile up, along with flowing through increasing of medium, washing cash or last cash are cumulative between block 3, long-pending more thick more, form the spoil wearing layer 4 of one deck gradually based on block 3.After through washing cash or last cash, can contact with this wearing layer 4, and the inwall of the chute 2 that directly do not wear and tear, thus reach the abrasion resistant purpose.
Claims (2)
1, a kind of wear-resisting chute is characterized in that: be provided with block (3) on the bottom of chute (2) and both sides inwall.
2. wear-resisting chute according to claim 1 is characterized in that: block (3) can be herringbone or rhombus is distributed on the bottom and both sides inwall of chute (2) according to the object flow direction.
