Description
Technical field
The present invention relates to a kind of drying equipment, especially relate to a kind of vertical stirring vacuum drier.
Background technology
At present, tray drier, vacuum rake dryer etc. are at medicine, chemical industry, agricultural chemicals, the widely used drying plant of food service industry.Tray drier generally is used for dried particles and the less material of viscosity, but it is unsuitable for cream is stuck with paste the drying of strong material; And rake type drier, though can stick with paste strong material by dry cream, but its discharging is unclean, if produce continuously, can influence the quality of back batch materials, simultaneously also can reduce original drying efficiency, and complex structure, bulky, whole dry heat transfer rate is the end relatively, production cost is higher, so above-mentioned drying equipment more and more can not satisfy the demand in market.
Summary of the invention
The objective of the invention is to propose a kind of vertical stirring vacuum drier, this drying equipment is applicable to the drying of the material particles of different viscosity, and particularly to the drying of pasty state or plaster material, its discharging is clean, and floor space is little, the heat transfer rate height.
Vertical stirring vacuum drier of the present invention comprises cylindrical shell, charging aperture, discharging opening, vacuum interface and the agitator that is provided with heating jacket, main shaft is connected with drives structure by shaft coupling, heating jacket is provided with heating agent inlet tube and leakage fluid dram, said cylindrical shell is vertical, the upper end is provided with end cap, and vacuum interface and charging aperture are located on the end cap, and the agitator main shaft stretches into cylindrical shell by end cap, the main shaft lower end is provided with symmetrically arranged rake arm, and the rake arm is provided with a plurality of blades.
Blade on the rake arm is even, the symmetrical distribution in center with the main shaft.
Described blade is the straight-plate-type rectangular configuration; Blade and the air line distance of tube between the end can effectively be turned over the material in the body like this and copy, mix less than 1cm, accelerate the rate of drying of material, and the while can be rapidly, clean material is discharged from discharging opening.
Described blade and the axial formation certain angle of harrowing arm, angulation are-45＜α＜45 degree.When the rake arm was made circular motion with main shaft, blade produced tangential thrust to the material of barrel, and the quickening material contacts with the cylindrical shell perisporium, improves the heat transfer efficiency of barrel, accelerates material and is heated dry speed.
Described end cap is provided with Butterworth Hatch, so that the cleaning in the tube.
Described heating jacket is provided with heat-insulation layer and outer seal outward.
Between described main shaft and end cap, black box is set, so that better reach the requirement of vacuum.
Be provided with support on described end cap, driving mechanism and shaft coupling are fixed on the support, to improve transmission efficiency.
Many group symmetry rake arms can be set on the main shaft.
Drying machine of the present invention adopts vertical cylindrical shell, and is simple in structure, and volume is little, greatly reduces the floor space of equipment; When dry tide material, do not return and overflow; The ratio of material and barrel contact area, frequency of exposure all improves a lot, and has accelerated dry efficient, has improved heat transfer rate, and after drying finishes, the discharge cylindrical shell that material can be clean very efficiently; Simultaneously since the direction of motion of blade and rake arm all perpendicular to self gravity direction, so its stressed relatively balance, evenly.
Description of drawings
Fig. 1 is the structural representation of vertical stirring vacuum drier of the present invention;
Fig. 2 is the A-A cutaway view of presentation graphs 1;
Fig. 3 is another embodiment of A-A cutaway view.
Among the above-mentioned figure: 1 is that supporting leg, 2 is that cylindrical shell, 3 is heating jacket for harrowing arm, 4,5 is end cap, 6 for advance the heating agent mouth of pipe, 7 for leakage fluid dram, 8 for charging aperture, 9 for Butterworth Hatch, 10 for discharging opening, 11 for main shaft, 12 for blade, 13 for black box, 14 for shaft coupling, 15 for variable-speed motor, 16 for motor, 17 for vacuumizing interface, 18 is support, 19 is heat-insulation layer, and 20 is outer seal.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.
Embodiment one: shown in Fig. 1 to 2: vertical support cylindrical shell 2 is provided with supporting leg 1, cylindrical shell 2 outsides are provided with heating jacket 4, heating jacket 4 is provided with into the heating agent mouth of pipe 6 and leakage fluid dram 7, heating jacket 4 outer heat-insulation layer 19 and the outer seals 20 of being provided with, cylindrical shell 2 upper ends are provided with end cap 5, end cap is provided with charging aperture 8, vacuumize interface 17, Butterworth Hatch 9 and support 18, barrel is provided with discharging opening 10, driving mechanism comprises variable-speed motor 15 and motor 16, be fixed on the support 18, driving mechanism is connected with main shaft 11 by shaft coupling 14, the lower end of main shaft 11 is stretched in the cylindrical shell 2 from end cap 5 centers, and with rake 3 vertical linking to each other of arm, it is even to harrow arm 3, be symmetrically distributed with blade 12, blade 12 is 0.5cm with cylindrical shell 2 distances from bottom.When main shaft 11 was driven in rotation, rake arm 3 rotated thereupon, and stirs by 12 pairs of materials of blade.Blade 12 is 45 degree with the axis angle [alpha] of rake arm 3.End cap 5 is fixedlyed connected with cylindrical shell 2, is provided with sealing ring therebetween, and black box 13 also is set between main shaft and end cap.
Main shaft is equipped with two groups of rake arms as shown in Figure 3, even can be more.
Specific implementation process is: material is by the charging aperture input, make in the cylindrical shell by heating jacket and to heat up, vacuumize by empty the adapter in 17 pairs of tubes of Zhao, material is heated drying under vacuum condition, agitator main shaft 11 is driven after reductor 15 speed governing by motor 16 simultaneously, drive the rotation of rake arm, mix by 12 pairs of materials of blade, because blade blade 12 barrel directions tilt, help material and constantly contact, improve the heat transfer rate of material, accelerated the drying of material with cylinder inboard wall, the moisture content of air in the cylindrical shell and dry evaporation is extracted out outside the cylindrical shell by vacuum subassembly, has improved drying efficiency; After drying finishes, open the valve of discharging opening because material is subjected to tangential force, help the discharge of material, simultaneously since at blade and an end gap less, material is easy to emptying.
