The working principle and model of the vertical dryer
Vertical dryer is drying in my company after a lot of practice, developed a highly efficient energy-saving products, has formed two invention patents, 6 utility model patents. The novel and unique structure of this vertical dryer, thermal efficiency, good drying effect, superior performance and technical indicators in a leading position in the peer, with international advanced level, is the replacement products for all kinds of domestic dryer.
vertical dryer manufacturer
Vertical dryer compared with today flowback drying oven, the investment amount reduced by 1/2; covers an area of its 1/5-1/3; significantly reduce energy consumption and operating costs.
The vertical dryer is designed for briquette and mineral powder pressed pellets dehydration. The key technology is to make the material can be decentralized as much as possible in the vertical dryer, hot flue gas and material contact area, and control materials in the various regions of the dryer flow rate and residence time, the hot flue gas and the material fully convective , radiation, conduction heat transfer.
Vertical dryer features:
Match the vertical dryer, easy connectivity and automated production lines and other equipment. Equipment easy to operate and simple maintenance. Drying furnace body without mechanical moving parts, and daily maintenance-free. Continuous operation, high efficiency, large output. Stick, dry coal to a large fertilizer plant, and achieved good results: coal rods into the gas furnace, water down to about 3%, gas production was significantly improved; save a lot of manpower, reduce labor intensity; save the site to expand the production.
The main structure of the vertical dryer:
Vertical dryer mainly consists of a fixed cylinder, air inlet device, and out equipment, heat exchange devices, thermal insulation devices constitute. This product is used in the dynamic vertical drying technology enables materials dispersed as much as possible to improve the area of the hot flue gas contact with the material, so that the hot flue gas and the material to full convection, radiation, conduction heat transfer within the dryer.
1.Saving investment, covers an area of 25㎡，no need workshop.
2.Internal adopts heat-resisting & wear-resisting alloy castings, long service life, convenient maintenance.
3. Thoroughly solved the big air leakage, not easy seal problem between dryer and furnace.
4. Countercurrent operation, high thermal efficiency, fast drying speed. Small exist concentration, just for 10g/m3.
5. Rely on gravity fall, no need power.
6. It Can use multiple grate basin, grate cone, adopts different angles and different spacing design; and its strong adaptability, suitable for drying slag, clay and sand, coal, iron powder, ore etc.
7. The microcomputer automatic detection control system can optimize adjust the dryer technological parameter on-line.
Vertical dryer it works:
After forming the “water polo” transported by belt conveyor to the furnace top, evenly distributed by the fabric devices to total cross section of the roof. Briquette side of its orbit by gravity slow down the side of the heat exchange with the strong winds. The briquette evaporation of moisture by the strong winds random away. Briquette evaporation process in about two hours to reach dry.
When temperature is showed from 400°C to 500°C by temperature controller on the bottom, materials, whose granularity is not more than 25mm, will be raised to preheating zone by lifter under the instruction of intelligent material level controller; When temperature is showed from 150°C to 250°C by temperature controller on the top, materials will be sent into cross vibration chute by electric shutoff device to take the second preheating. During the vibration-preheating course, materials are dried and loose and evenly distributed into several overlapped distribution cones to take the third drying process till the materials are completely dried and finally discharged.

This type of vertical dryer is made of steel structure; inner lining adopts heat preservation materials to keep warm; multilayer high temperature castings are adopted in the roaster; there are vibration system, interception system, temperature control system and intelligent control system installed on some relevant parts of the machine; vapor and smoke are collected with the application of a draught fan and a cyclone dust collector.
vertical dryer Application:
1. Coal powder is pressed into shapes by briquette press machine; the moisture is usually at 12%-14%. After dried, the moisture can reduce to 2-4%, also can satisfy the request of hardness, storage and transportation. On that basis, then through adaptability reform, the moisture can reduce to less than 1.5%; Also can dry briquetting，coal rods etc. Particulate matter.
2. Vertical dryer is mainly used for some spherality or granular materials which contain much moisture, for making them reach the desired strength after drying. Compared with the rotary dryer, the best feature is that vertical dryer can reduce the crash between finished products and barrel & lifting plate during the drying process, guarantee the final products failure reduce to the lowest level.
