4.Working principle

Hollow Blade Dryer heat transfer surface have blades, stirring shaft parts, wall, etc., and leaves a large part of the heat transfer area, the equipment, compact structure, large heat transfer area per unit volume. In addition, the stirring and mixing the material turning violent, resulting in very high heat transfer coefficient, so the area is very small and space, saving the plant capital costs. Drying process with less gas, the flow rate is low, being less dust entrained gas, so convenient drying gas dust recovery, recycling equipment, small size, can save equipment investment. The need for recovery of the solvent drying process, can greatly improve the solvent concentration. Due to the special blade structure, the material received alternately squeezing and relaxation during the drying process, and strengthen the dry. A high rate of drying chamber filled materials, can reach 80% -90%, the residence time of materials by adjusting the feed rate, stirring shaft speed, full of material and other parameters is adjustable from a few minutes to a few hours be adjusted. In addition, the material in the Dryer from the feed port to the outlet of a substantially piston movement, residence time distribution is narrow, and thus uniform product moisture content. Paddle agitator shaft having an axial angle, the material can be dried continuously.



5.Structure

In two-axle example to explain the structure (hollow blades Dryer can be divided into single, double, four). It consists of jacketed end faces W-shaped casing, cover, two bladed hollow shaft, end caps at both ends, through a rotary joint media, metal hose and gears, sprockets and other parts of the transmission mechanism comprises composition.

It is the core equipment and welding two hollow shaft stirring blade in the hollow shaft. Blade shape of a hollow semi-circular wedge, can pass into the heating medium. Apart from the stirring effect, but also the heat transfer body of the device. Heat two main beveled side of the blade, so when the material in contact with the slope, with the rotation of the blades, the particles quickly slid the incline, the heat transfer surface constantly updated, enhanced heat transfer. At the bottom of the blade has a triangular blade to the bottom of the material deposited on the shell blowing and prevent dead.

Blade arrangement and the size of each part have certain requirements, but also in the feed zone, drying zone, the discharge zone in addition to the blades, the other an auxiliary mechanism to ensure the stability of the whole operation, uniform drying. In addition, the residence time can also be adjusted.



6.Application

Heat generated by the equipment required for drying depend on heat conduction indirectly heated, so the drying process without or with little gas away wet parts. Greatly reducing the loss of heat was taken away this part of the airflow, improving heat efficiency, it is an energy-saving Drying equipment. Paddle Dryer is widely used in drying petrochemical, chemical, metallurgy, food, medicine, pesticide and other industries powder, granular, cake-like slurry-like material.


On the basis of absorbing foreign advanced technology, improve and optimize the design of the wedge-shaped hollow blades Dryer, can paste, granules, powders, slurries indirect heating or cooling can be accomplished drying, cooling, heating, sterilization, reaction, low temperature calcination unit operation. Devices special wedge heat stirring blades, has a high heat transfer efficiency and heat transfer surface self-cleaning function.

It has been successfully used in the food, chemical, petrochemical, dyes, industrial sludge and other fields. Heat transfer equipment, cooled, stirred solution of the following characteristics makes it possible to complete the unit operations: calcination (low temperature), cooled, dried (solvent recovery), heating (melting), the reaction and sterilization. Stirring blades while the heat transfer surface, so that the heat transfer area per unit effective volume is increased, the processing time is shortened. Wedge-shaped blade heat transfer surface and having a self-cleaning function. Compression - expansion of the material mixture evenly mixing function. Material axially into a "plug flow" movement in the axial zone, material temperature, humidity, mixing gradient is very small.


Used to do medium heat, paddles Dryer work to be completed by low temperature calcination. Such as: calcium sulfate dihydrate (CaSO4 · 2H2O) calcining is converted to calcium sulfate hemihydrate (CaSO4 · 1 / 2H2O). Sodiumbicarbonate (NaHCO3) into calcined soda ash (Na2CO3) and the like.

Pass into a cooling medium, such as water, salt water, etc. can be used to cool the cooling. Such as: used in the soda ash industry paddle cooler base machine, replace the old air-cooled cooler base machine, energy saving and exhaust gas treatment equipment, reduce operating costs, but also for titanium, nickel-iron alloy powder and various granular powder cooling the material. In a single machine in the material can be cooled from 1000 ℃ to less than 40 ℃.


Drying, the main function of the device, do not use hot air, the solvent recycling, energy consumption, environmental control in the ideal state tractable. To be recovered solvents, flammable material is particularly heat-sensitive oxide adaptation. It has been widely used in chemical, petrochemical and dye industries.

Axial area, temperature, humidity, degree of mixing uniformity, so that the device can be used to heat or melt, some of the solid material or the reaction. It has been successfully used in the fertilizer industry and modified starch. Dryer blade can be used for sterilization of food and flour. Unit effective volume of large heating area, will soon be heated to the sterilization temperature, avoiding prolonged heating to change the quality of materials.
