Abstract
The utility model relates to a novel drying roller, including the cylinder body, the cylinder body includes outer barrel, middle level barrel, inner layer cylinder body, the outer barrel and the cooperation of middle level barrel position of the feed end department of cylinder body set up first closing plate, the middle level barrel and the cooperation of inner layer cylinder body position of the discharge end department of cylinder body set up the second closing plate. The utility model discloses can increase the speed of marcing of fast material, avoid the material condition that long -pending material blockked up to appear, avoid the material phenomenon of carbonization to appear.
Description
Technical field
The utility model relates to plant equipment, particularly relates to a kind of novel drying roller.
Background technology
Roller drying machine is primarily of revolving body, lifting blade, and transmission device, bracing or strutting arrangement and seals and other component form.Drying machine is one and slightly becomes the cylinder of inclination with horizontal direction, and material adds from higher one end, and high-temperature hot flue gas and material also flow to into cylindrical shell, and along with the rotation of cylindrical shell, material runs to lower one end due to the effect of gravity.Cylinder inner wall is equipped with flight, material is taken up and spills down, the contact surface of material and air-flow is increased, to improve rate of drying and to promote that material moves ahead.Dried product is from bottom collective low.
But there is following defect in the cylindrical shell of existing drying roller, existing high-temperature gas is retrograde manner with the mode of advancing of material in the middle level cylindrical shell of cylinder, and high-temperature gas overall walking line in cylinder is short out, and heat exchanger time is short, heat exchange is insufficient, and thermal loss is large.Drive in the wrong direction in process at middle level hot blast drum and material, light material is under the acting in conjunction of flight and wind direction, and the gait of march of material is slow, occurs that buildup blocks time serious.At cylinder feed end, material by middle level transfer enter skin time, easily cause material carbonization, breaking out of fire time serious because the high and material of temperature is dry.
Summary of the invention
For the defect that prior art exists, the utility model proposes a kind of novel drying roller, the gait of march of material can be speeded, avoid material to occur the situation that buildup blocks, avoid material to occur the phenomenon of carbonization.
For achieving the above object, the utility model proposes a kind of novel drying roller, comprise roll body; Described roll body comprises outer layer barrel, middle level cylindrical shell, internal layer cylinder; Outer layer barrel at the feed end place of described roll body and cylindrical shell position, middle level are equipped with the first sealing plate; Middle level cylindrical shell at the discharge end place of described roll body and internal layer cylinder position are equipped with the second sealing plate.
Described first sealing plate is metal foil, and the first sealing plate enables hot-air enter drums inside from internal layer cylinder.
Described second sealing plate is metal foil, and the second sealing plate coordinates with the first sealing plate enables hot-air first enter the space between middle level cylindrical shell and internal layer cylinder from internal layer cylinder, then makes hot-air enter into space between middle level cylindrical shell and outer layer barrel.
Beneficial effect:
The outer layer barrel of the utility model by arranging, middle level cylindrical shell, internal layer cylinder, the first sealing plate and the second sealing plate, make high-temperature gas walking route in cylinder long, heat exchanger time is long, and heat exchange is abundant, and thermal loss is little; The gait of march of material is accelerated, and single solution buildup clogging also improves the production capacity of equipment.At cylinder feed end, material by middle level transfer enter skin time, overcome and easily cause material carbonization because the high and material of temperature is dry, and the generation of fire.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
1. outer layer barrel, 2. middle level cylindrical shell, 3. internal layer cylinder, 4. the second sealing plate, 5. discharge end, 6. roll body, 7. feed end, 8. the first sealing plate.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in the figure, a kind of novel drying roller, comprises roll body 6; Described roll body 6 comprises outer layer barrel 1, middle level cylindrical shell 2, internal layer cylinder 3; Outer layer barrel 1 at feed end 7 place of described roll body 6 and middle level cylindrical shell 2 position are equipped with the first sealing plate 8; Middle level cylindrical shell 2 at discharge end 5 place of described roll body 6 and internal layer cylinder 3 position are equipped with the second sealing plate 4.
Described first sealing plate 8 is metal foils, and the first sealing plate 8 enables hot-air enter drums inside from internal layer cylinder 3.
Described second sealing plate 4 is metal foils, second sealing plate 4 coordinates with the first sealing plate 8 enables hot-air first enter the space between middle level cylindrical shell 2 and internal layer cylinder 3 from internal layer cylinder 3, then makes hot-air enter into space between middle level cylindrical shell 2 and outer layer barrel 1.
This novel drying roller makes high-temperature gas walking route in cylinder long, and heat exchanger time is long, and heat exchange is abundant, and thermal loss is little.Have to drive in the wrong direction at middle level hot blast drum and material and become direct motion, lightweight dry material is under the acting in conjunction of flight and wind direction, and the gait of march of material is accelerated, and singly solves the production capacity that buildup clogging also improves equipment.At cylinder feed end, material by middle level transfer enter skin time, overcome and easily cause material carbonization because the high and material of temperature is dry, and the generation of fire.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
