Description
Technical field
The present invention relates to powder body cooling field, particularly belong to a kind of low-resistance swirled air formula powder body cooler.
Background technology
Prior art for the cooling of granular material be mainly the spiral cooler of vertical tube, oblique slot type cooler,
Complex-cooling devices etc., are mainly monotubular cooler, many coolers, comb formula for the cooling of lump material cold
But device etc..See figure classification number is: in the periodical " Sichuan cement " of TQ172.622.4 2008 the 4th
" 1.1 vertical tube spirals in the phase paper of page 8 " the Energy Efficiency Analysis contrasts of a several cement types of cooling " literary composition
Formula cooler " and " 1.2 oblique slot type cooler " etc..Application No. CN201310122101 can also be referred to,
Open (bulletin) number is the patent of invention " a kind of air cooler " of CN103225959A, and application number
For CN201320670900, open (bulletin) number is that the utility model patent of CN203561231U is " compound
Cooled powder body cooler ".
The book number that also see 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's handbook " page 396 2.5.5
Joint " chamotte cooler ", comprises " one, single cylinder cooling machine " of page 396, page 398 " two, many
Cooler ", and " three, slide slotted cooler " of page 401 etc..
The spiral cooler of existing vertical tube and oblique slot type cooler, be generally used for the cooling to granular material,
Particularly the finished cement etc. just going out mill is cooled down.The spiral cooler of vertical tube connects cooling water except needs
Outside, it is necessary to the power providing extra is stirred, and structure is complicated, and power consumption is big, easily leads because of abrasion
Cause is leaked, and finds the most in time if leaked, and also results in cement setting, thus scraps cooler.
Existing oblique slot type cooler, powder material streamlined flow thereon, speed is the fastest.On the one hand,
Heat pipe is the ofest short duration with the time of contact of material, and heat transmission is 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 patent of invention " a kind of air cooler " of CN103225959A, and
Open (bulletin) number is the utility model patent " composite cooling powder body cooler " of CN203561231U,
All because height is high, volume is big, powder material is difficult to shed completely come, and cooling effect is restricted, necessarily
Exploitation and the popularization of technology is have impact in degree.
Existing monotubular cooler, many coolers, comb formula coolers etc. are generally used for the bulk to high temperature
Material cools down, particularly to the high-temperature cement of firm kiln discharge somehow etc. carry out on-line cooling.This kind equipment except
Need to provide beyond powerful cooling wind, it is necessary to be equipped with extra power source, be used for driving moving component to do
Gyration or reciprocating motion, structure is complicated, equipment is heavy, floor space is big, investment is high, efficiency is low.
