Sub- dryer.The effect beneficial of both dryers is extremely similar, all possesses that precipitation range is big, one-time investment is few, occupation of land face
Product is small, the coloury feature of sand after drying.It substantially represent direction and the level of China's dryer development.But could not
Although what is recognized is that the dryer in China has the advantages of above, its compared still with the advanced dryer of foreign countries have it is a lot
Drawback.Such as：1. domestic sand dryer is easily on fire in use.The dried medium of the domestic sand dryer in China
All got by heat exchanger for hot-blast stove heating cold air.And between heat exchanger end plate and expansion joint, heat exchanger end plate with heat exchange
Between pipe, between heat exchanger and heat exchanger, because easily there is hole and crack in prolonged calcination, corrosion and aging.At this
The pressure of the outer dried medium of Shi Ruguo heat exchanger tubes is less than the pressure of heat exchange inner tube smoke, and the kindling material in flue gas will pass through this some holes
Hole and crack are drawn onto among dried medium, are then taken to due to dried medium in dryer and are caused sand to catch fire.It is this kind of to catch fire
Accident is occurred inside drier body, and operating personnel are typically not easy to find and prevent.After on fire, in cylinder
Sand will be burnt, and so as to lose value, scrapping for dryer can be caused when serious, for producing and having invested greatly
Influence.2. sand after drying machine drying is half-cooked, the amount of losing.Present most of producers using sand dryer are all in custodian
The moisture laboratory test report for the sub and dry sand of wet sand that member provides according to dried medium temperature, ambient temperature and lab technician, with warp
Test manually adjust sand discharge handset rotating speed control dry after sand moisture.After adjusting, operating personnel are not allowed at will to adjust
Whole sand machine.For this method when running into sand moisture and changing, the sand produced generally is unable to reach requirement, shadow
Production efficiency is rung, and half-cooked sand easily makes sand nest shape generate heat and bad sand accident occur.
