Description
Technical field
The utility model relates to powder cooling technology field, and relating generally to is a kind of bend shape slow flow type powder cooler.
Background technology
Prior art for the cooling mainly spiral cooler of vertical tube, oblique slot type cooler, the Complex-cooling device etc. of granular material, for cooling mainly monotubular cooler, many coolers, the comb formula coolers etc. of lump material.Can consult middle figure classification number is: " the spiral cooler of 1.1 vertical tube " and " 1.2 oblique slot type cooler " in the periodical " Sichuan cement " of TQ172.622.4 in the 4th phase paper of the 8th page " the Energy Efficiency Analysis contrast of a several cement type of cooling " literary composition in 2008 etc.
Can also consult application number is CN201310122101, open (bulletin) number is the utility model patent " a kind of aerial cooler " of CN103225959A, and application number is CN201320670900, open (bulletin) number is the utility model patent " composite cooling powder cooler " of CN203561231U.
The book number also can consulting China Construction Industry Press's in May, 1989 publication is: ISBN7-112-00388-1/TU.276 books " Small and Middle Scale Cement Plants equipment worker handbook " the 396th page of 2.5.5 joint " who knows cooler ", comprise " one, single cylinder cooling machine " of the 396th page, " two, planetary cooler " of the 398th page, and " three, slide slotted cooler " of the 401st page etc.
The spiral cooler of existing vertical tube and oblique slot type cooler, be generally used for the cooling to granular material, particularly cools the finished cement etc. just going out mill.The spiral cooler of vertical tube, except cooling water connected by needs, also must provide extra power to stir, complex structure, power consumption is large, easily because wearing and tearing cause leaking, does not have Timeliness coverage if leaked, also can cause cement setting, thus scrap cooler.
Existing oblique slot type cooler, the powder material streamlined flow on it, speed is too fast.On the one hand, the time of contact of heat pipe and material is too of short duration, and heat transmits insufficient, and heat-transfer effect is poor.On the other hand, heat pipe directly contacts with the powder material of high speed slide, and wear problem is difficult to solve.
Open (bulletin) number is the utility model patent " a kind of aerial cooler " of CN103225959A, and open (bulletin) number is the utility model patent " composite cooling powder cooler " of CN203561231U, all because of highly high, volume is large, need supportingly to arrange dust collection device, have impact on exploitation and the popularization of technology to a certain extent.
Existing monotubular cooler, many coolers, comb formula coolers etc. are generally used for and cool the lump material of high temperature, particularly to who knows etc. the high-temperature cement of firm kiln discharge and carry out on-line cooling.This kind equipment, except needing to provide powerful cooling wind, also must be equipped with extra power source, do gyration or reciprocating motion for brought into motion parts, and complex structure, equipment are heavy, floor space is large, it is high to invest, efficiency is low.
