Product DescriptionDescription:Densely lined with wedge-shaped hollow shaft hollow blades, heat medium through the hollow axial flow through blades. Unit effective volume of a very large area of heat transfer, heat medium temperature from-40℃ to 320℃, can be water vapor, may also be liquid type: such as water, oil and so on. Indirect conduction heating the air does not carry away the heat, the heat are used to heat materials. Only through the device body heat loss to the environment, heat insulation layer. Wedge shaped blades with self-cleaning heat transfer surfaces. Wedge-shaped surface material particles and scrubbing effect relative movement, to wash away the wedge surface material attachments, so in operation have maintained a clean heat transfer surfaces. Blade dryer for the W-type shell, the shell of the general arrangements for 2-4hours stirring shaft. Shell with a sealed cover with the cover to prevent dust leakage and collection of materials, solvent vapor materials. Set out and exit pull a block, to ensure a high degree of material level, so that heat transfer surface is covered with fully material. Heat medium through the rotary joint, passing through the shell jacket and the hollow stirring shaft, hollow shaft stiffing according to the type of thermal media have different internal structures to ensure the best heat transfer.
Features:1. Blade dryer energy consumption is low: as indirect heating, the air does not carry away a lot of heat insulation of dryer wall has, on the slurry material, evaporation of 1kg of water vapor only 1.22kg of steam.2. Blade dryer system costs low: within the effective volume of units have a large heat transfer surface. The reduced processing time, equipment size becomes smaller. Would greatly reduce the building area and building space.3. Dealing with a wide range of materials: using a different hot medium, able to deal with heat-sensitive materials can be heat-treated materials handling. Commonly used media are: water, steam, oil, hot water, cooling water. Continuous operation can also be intermittent operation can be applied in many fields.4. Environmental pollution: do not carry air, dust entrainment few materials. Solvent evaporation of material is very small, easy to handle. To have contaminated materials or be recycled solvent conditions, can be used closed circuit.5. Operation stability: as the wedge-shaped blades of special compression expansion of stirring, so that material particles sufficient surface contact with the heat transfer in the axial zone, the material temperature, humidity, mixed density gradient is very small, thus ensuring the process stability.Blade dryer body:The blade dryer tank is cylindrical, and the equipment consists of a tank body, a stirring shaft and a blade, an end cover, a frame, a motor, a speed reducer, a control cabinet and the like. Tank body: heat transfer type for the jacket wall, outer wall insulation structure, the upper part is provided with feeding port, heat medium inlet and outlet, temperature meter nozzle, pressure gauge nozzle and so on. Agitating shaft: The blade is welded on the stirring shaft, and the blade near the barrel cleans the material attached to the wall of the cylinder during the rotation process, so that the heat transfer surface of the partition wall is continuously updated, which is favorable for material mixing and heat conduction. Sealing device: The rotary seal between the shaft and the end cap is fitted with a mechanical
seal according to the material and process requirements. End cover: with mirror, rotary seal, bearing seat and so on. Rack: It is the component that sets the drive of the paddle dryer. It is usually made of channel steel or thick-walled square tube. Discharging device: consists of valve seat, gasket, valve plate, etc. Transmission mechanism: It consists of motor and reducer. The speed reducer and the stirring shaft are directly connected by the coupling. The belt drive between the reducer and the motor can avoid the stirring blade caused by unforeseen debris entering the inside of the tank. Damage to the agitator shaft or seal when it is stuck with the tank and is not found. In order to protect the continuous and effective rotation seal, the drive motor generally adopts frequency conversion speed regulation.
Heat source:conducting oil/steam/hot waterHeating box of conducting oil Conducting oil to do with the heat medium, max drying temperature 180-300℃;Heating with electricity, power of 36kw.
Screw feeder:Helical screw conveyor is driven by the motor rotation, promote material to achieve the transport machinery, it can level, tilt or vertical transmission, is the ideal transport all kinds of powder granular equipment. Motor power 1.1kw.
Wet dust collector :The cylinder is a circular cylinder, and water enters the cylinder from the upper part of the precipitator, so that a water film is formed on the inner wall of the cylinder from top to bottom. The flue gas is tangentially entered from the lower part of the cylinder and rotates in the cylinder. Ascending, the dust-containing gas always rubs against the water film on the inner wall of the cylinder under the action of centrifugal force, so that the dust-containing gas is wetted by the water film, and the dust particles flow with the water to the bottom of the dust collector, and are discharged from the overflow hole. The bottom of the cylinder is sealed at the bottom and a water sealing groove is provided to prevent the flue gas from leaking from the lower part, and the cleaning hole is convenient for cleaning the bottom of the cylinder. After dedusting, the wastewater is discharged from the bottom overflow hole into the sedimentation tank, neutralized by precipitation, and recycled. The purified gas is taken out through the upper cone portion of the cylinder to achieve the purpose of dust removal
