Abstract
The invention discloses a low-resistance vortex air type powder cooler which comprises a vortex outer shell, wherein an air outlet pipe is arranged on the outer shell, and is connected to an air path system in a negative pressure state, so that the cooler runs in the negative pressure state, and cooling air subjected to heat exchange and a powdery material carried by the cooling air are discharged out of the cooler from the air outlet pipe; an air inlet communicated with atmospheric air is formed in the outer shell, and the atmospheric air is sucked into the cooler from the air inlet to be turned into the cooling air in the negative pressure state, and the cooling air runs from outside to inside to form a flow field of the cooling air in a vortex state; a material curtain moves downwards under the action of own inertia, gravity and the like, and falls into the flow field of the cooling air in the negative pressure state, and the high-temperature powdery material carried by the air runs together with the air to form heat exchange so as to be cooled; a dust hopper is arranged on the lower part of the outer shell, and is used for collecting and discharging the falling material which is not carried away by the cooling air.
Description
Technical field
The present invention relates to the cooling field of powder, specifically belong to a kind of low-resistance vortex air type powder cooler.
Background technology
Prior art is mainly the spiral cooler of vertical tube, oblique slot type cooler, Complex-cooling device etc. for the cooling of granular material, for lump material cooling, is mainly monotubular cooler, many coolers, comb formula cooler etc.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 contrasts of a several cement types of cooling " literary composition in 2008 etc.Can also consult application number is CN201310122101, open (bulletin) number is the patent of invention " 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 that also can consult China Construction Industry Press's in May, 1989 publication is: the 396th page of 2.5.5 joint of ISBN7-112-00388-1/TU.276 books < < Small and Middle Scale Cement Plants equipment worker handbook > > " chamotte cooler ", " one, single cylinder cooling machine " who comprises 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 cooling to granular material, particularly to just having gone out the finished cement etc. of mill, carries out cooling.The spiral cooler of vertical tube, except needs are connected cooling water, also must provide extra power to stir, complex structure, power consumption is large, easily, because wearing and tearing cause leaking, if leaked, does not find in time, also can cause cement setting, thereby 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 patent of invention " 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, powder material is difficult to completely shed and come, cooling effect is restricted, and has affected to a certain extent exploitation and the popularization of technology.
Existing monotubular cooler, many coolers, comb formula cooler etc. are generally used for and the lump material of high temperature are carried out cooling, particularly the high-temperature cement of firm kiln discharge be who knows etc. and to be carried out on-line cooling.This kind equipment, except providing powerful cooling with wind, also must be equipped with extra power source, and for driving moving component to do gyration or reciprocating motion, complex structure, equipment is heavy, floor space is large, it is high to invest, efficiency is low.
