Jiangsu haihua Sleeve type double tube dryer

The material moisture can reach 1-0.5% below after drying. Reduce operator, save labor resources

thisDouble tube of horizontal dryer mainly used for drying certain humidity and particle size range particle materials, such as the dry mix mortar industry used the yellow sand ranks, foundry industry of various kinds of specifications with sand, building materials with blast furnace slag cement industry, small size clay, chemical industry can't afford for chemical changes, not afraid of high temperature and dust dirty little particle materials. According to the different industries to end after drying materials water requirements, after drying of material moisture can reach 1-0.5% below.Enter the materials in the dryer with not sticky and Yang materials plate inner advisable. The exchange of gases into the dryer internal temperature higher than 750 °C is unfavorable for special requirement high temperature drying, the entrance of the dryer tube and Yang materials plate heat resistant steel manufacturing available.

Working principleAbout fluidized bed by produced by burning hot flue gas, through the mixing chamber adjustment, the temperature of 800 ~ 850 °C state into the dryer, feeding system will be less than 30 mm material feeding the dryer gets the tropical, the incoming spiral, spiral shape of the horns of the disc and Yang Yang figure all under the action of material combination of material was pushed, scatters, preheating, gradually entered the drying belt.

Drying of material in the corner with shape Yang disc and all glyph Yang material common role in the cylinder body formed whole section of material and heat flow evenly, fully contact and be drying, after drying of material in the corner form disc push to raise between inside and outside cylinder. In the tropical, drying with through the process of dry, with, materials and heat flow constantly heat, heat convection and radiation, conduction by way of transfer to the material, the last in the material and material spiral guide material cone under the common function of unloading unable to fall into the device. The material of water evaporation out with dusty gas from the dryer vent unloading the upper portion of the pipe into the device used to collect dust, the clean air into air, take the dust and drying of material inventory has together. Can be seen from the material flow, material by a tube in internal air drying directly at the same time, they were another in the cylinder heat indirect drying, low temperature and the temperature of the tube to the inner cylinder have adiabatic effect. The tube is the material and hot gas heat radiation, between with convection heat transfer for the Lord; And outside tube, hot gas high humidity, temperature is lower, the material, the cylinder wall is an endlessly picturequre scene, the heat conduction, convection heat transfer to simultaneously. The mechanism of drying, scientific and advanced reasonable.

Structure:I company of production HHSH double tube of horizontal dryer is a direct heat transfer type of rotary dryer, mainly by inside the cylinder body, the barrel, "wheel, LunDai support device, gearing, feeding intake device by unloading equipment etc.
