Description
Technical field
The utility model relates to a kind of chute device that is used for powder concentrator, is applicable in the powder concentrator of grinding system in the industries such as building materials, chemical industry, metallurgy, power plant, mine.
Background technology
Powder concentrator is one of important grinding system equipment, material enters powder concentrator from chute, by chute material is imported the grinding unit, material is entered powder concentrator by levigate back with the internal gas flow direction, the double action of guide vane in powder concentrator and rotation cage wheel issue estranged from.Fine powder continues to rise and flows out from the powder concentrator air outlet, gathers dust and collects via rotoclone collector, bag.Meal sedimentation under cage wheel centrifugal force and self gravitation effect enters grinding unit grinding once more via the powder concentrator ash bucket.Because of each manufacturer's raw material sources difference and production technology and purpose have bigger difference, the material attribute difference that enters from chute is very big.Generally speaking, if the material hardness of feeding higher, it is just big more to wearing and tearing of institute's contact material, to a certain degree will cause the damage of chute and causes shutdown maintenance when wearing and tearing run up to.If the material institute water content of feeding bigger, then cause the bonding of material and chute inwall easily, make more and more littler finally the blocking fully in chute blanking cross section and cause shutdown maintenance.Above problem often takes place in the powder concentrator use repeatedly, especially when feeding raw material is slag, because of slag abrasiveness and humidity are bigger, causes regular shutdown to overhaul, and has a strong impact on normal production.Also proposed multiple solution now both at home and abroad, the method for main flow is to add the wearability that abrasion-proof backing block improves chute, uses air bubble to prevent the chute putty.But traditional regular liner plate has following defective: the liner plate seam crossing does not have the high-abrasive material protection easily to cause the wearing and tearing of chute body; the liner plate fixed form is difficult to change for welding causes liner plate; the most serious is because very close to each other between regular liner plate and the chute; the air gun tube can only could insert in the chute in the abrasion-proof backing block upper shed; material from chute by the time stop up the air gun tube because do not block easily in the air gun tube, to heap; under air bubble pipe plug plug situation, carry out the air bubble winding-up and cause device damage easily; and the air gun tube can't be installed by material blanking direction and cause blowing direction and cutting mode inconsistent, and the block clearing effect is limited.In fact because of above reason, the scheme that abrasion-proof backing block adds air bubble is difficult to realize and abandoned substantially that single abrasion-proof backing block or air bubble injection method can not solve wear-resisting and anti-blocking problem again simultaneously in reality.Secondly, traditional this body section of blanking chute mostly is rectangle, and the defective in the blanking cross section of rectangle is: the cross section wearing and tearing are inhomogeneous, the dead angle is arranged, easy buildup.
The utility model content
The purpose of this utility model is: at the deficiencies in the prior art, provide a kind of and can reach a kind of powder concentrator chute device that wear-resisting requirement can prevent putty again.
The purpose of this utility model realizes by following technical proposals:
A kind of wear-resisting anti-blocking chute device that is used for powder concentrator, comprise the chute body, abrasion-proof backing block, air bubble and air gun tube thereof, also comprise air ducting, described some abrasion-proof backing blocks begin downwards arranged stacked continuously from the charging aperture of chute body, overlap in a last abrasion-proof backing block lower edge and adjacent next abrasion-proof backing block upper edge, and leave the gap between both overlapping parts up and down, described air ducting is located at the gap location of abrasion-proof backing block lower edge and chute body, the chute body of corresponding described air ducting position is provided with opening, and the air gun tube of described air bubble is communicated with described air ducting by this opening.
As optimal way, described abrasion-proof backing block is small top and big bottom watt shape, and bottom face is provided with leg.
In the such scheme, small top and big bottom structure is convenient to up and down that abrasion-proof backing block superposes continuously, and leg makes the perk of liner plate rear end, both has been convenient to stack, also makes up and down between abrasion-proof backing block of stack, and produces the gap between abrasion-proof backing block and chute body.
As optimal way, described abrasion-proof backing block inserts the chute body by its leg and fixes.
In the such scheme, fixing simple and reliable, easy installation and removal is convenient to change.
As optimal way, described chute body and abrasion-proof backing block cross section all are the C type.
In the such scheme, chute body and abrasion-proof backing block cross section are the C type, can effectively prevent the dead angle putty, and block clearing is convenient, handling ease.
As optimal way, described air ducting is uncovered box-like of bottom surface and downside.
The beneficial effects of the utility model: adopted a watt shape liner plate owing to abandoned traditional regular liner plate, after this watt shape liner plate superposes continuously, up and down between abrasion-proof backing block of stack, and leave the gap between abrasion-proof backing block and chute body, make chute have enough spaces that air gun tube and air ducting are installed below watt shape liner plate, realized the perfect adaptation of the wear-resisting and choke preventing function of chute when allowing material pass through smoothly.Because watt shape liner plate tool wearability and be modularization and fix with inserted mode has realized the wearability of chute by irregular replacing.Under the rectified action of air ducting, the winding-up wind that air bubble sends enters chute by the air gun tube, can precisely impact choke preventing function from chute to the material that bonds that realize.Because chute body and abrasion-proof backing block cross section are the C type, can effectively prevent the dead angle putty, block clearing is convenient, handling ease.The utility model compactness simple for structure is changed easily, and is easy to maintenance, solved puzzlement technical problem for many years, reduced the multiple loss that stop production to overhaul brings, and improved the effective running rate of equipment.
