Abstract
The utility model relates to drum-type drying equipment in a kind of microwave vacuum case, it is characterized in that: be made up of critical pieces such as microwave vacuum case, cylinder, digital pressure switch, microwave magnetron, microwave power controller, sealed rotation shaft, buncher, vavuum pumps.Cylinder is contained in microwave vacuum case, drive dry materials, supported by rolling wheel support bottom drum front end, drum rear wall central authorities connect sealed rotation shaft, sealed rotation shaft is fastening by two ends sealing flange, and separately there is silicone rubber for sealing circle centre, rear end connection for transmission chain, drive and variable-speed motor, and control the vacuum in microwave vacuum case, to ensure that in microwave vacuum case, vacuum remains on the vacuum ranges of setting by high accuracy number pressure switch.Make material under vacuum microwave condition along with cylinder rotates thermally equivalent, to obtain good drying effect.
Description
One, technical field
The utility model relates to vacuum microwave processing unit (plant), particularly drum-type drying device in microwave vacuum case.
Two, background technology
Micro-wave vacuum is expanded refers to the dry expanding processing utilizing microwave energy to carry out material under vacuum.Microwave penetration power is strong, can go deep into internal batch, and make inside and outside simultaneously intensification of material form overall heating, drying time shortens greatly; Due to internal moisture rapid vaporization and migration, produce powerful in external driving force, expandable interior institutional framework, loose, the uniform microcellular structure of product formation can be made, play Swelling Functions; Meanwhile, vacuum environment can allow moisture rapid evaporation at a lower temperature, makes material can carry out drying under cryogenic, also can prevent the oxidation reaction of material simultaneously.Current domestic vacuum microwave drying device is that material is positioned in vacuum cavity pallet substantially, with pallet tumble dried, material self is static, there is material moisture discharge fast and can not evaporate in time, vacuum is caused to decline, material is heated the uneven dry mass affecting material, and single treatment amount is little, has placed restrictions on industrialization production.
Three, summary of the invention
Technical problem
The purpose of this utility model is to provide a kind of cylinder being contained in adjustable rotating speed in microwave vacuum case, make material realize self stirring in dry run thus be more conducive to the timely evaporation of moisture content, and compressed switch by numeral and automatically control vacuum in microwave vacuum case, make it remain on drum-type vacuum microwave processing unit (plant) in setting vacuum ranges.
Technical scheme
1) the purpose of this utility model is the deficiency avoiding existing technology, a kind of cylinder that can rotate in microwave vacuum case is provided, make material realize self stirring thermally equivalent transpiring moisture in dry run, structure is simple, micro-wave vacuum equipment easy to use.
2) for achieving the above object, the technical scheme that the utility model is taked is: a kind of microwave vacuum drum-type drying equipment, comprise bottom drum front end and being supported by rolling wheel support, drum rear wall central authorities connect sealed rotation shaft, sealed rotation shaft is fastening by two ends sealing flange, separately there is sealing rubber ring centre, rear end connection for transmission chain, drive and variable-speed motor, is regulated the rotating speed of cylinder by buncher.
3) vacuum in microwave vacuum case is controlled further by high accuracy number pressure switch, when vacuum force value is higher than setup pressure value, vacuum pumping pump shuts down automatically, when low vacuum in casing is in the value set, vavuum pump starts running rapidly automatically, and in microwave vacuum case, vacuum remains in the scope of setting.
Compared with prior art, the beneficial effects of the utility model are: device cylinder in microwave vacuum casing, make in dry materials process, can thermally equivalent, reduce the inhomogeneities of material moisture evaporation, and by Automated condtrol microwave enclosure vacuum, make material moisture pass through to vacuumize mode and discharge in time, dry materials better effects if.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, utility model is further described.
Accompanying drawing is a kind of drum-type vacuum microwave dryer schematic diagram
In figure: 1, vavuum pump 2, device housings 3, microwave power controller 4, vacuum-pumping tube 5, rolling wheel support 6, door for vacuum chamber 7, microwave vacuum case 8, microwave magnetron 9, digital pressure switch 10, " S " scraping blade 11, cylinder 12, sealed rotation shaft 13, draining valve 14, driving chain 15, buncher 16, drive 17, equipment distribution box 18, universal wheel
Detailed description of the invention:
Below in conjunction with accompanying drawing, (but not being the restriction to the utility model scope) is elaborated to concrete structure of the present utility model
As shown in Figure 1, feature of the present utility model is that a kind of cylinder (11) is arranged in microwave vacuum case (7), drum front end is supported by rolling wheel support (5), drum rear wall central authorities connect sealed rotation shaft (12), sealed rotation shaft is fastening by two ends sealing flange, separately there is sealing rubber ring centre, sealed rotational shaft rear end connection for transmission chain (14), drive (16) and buncher (15), the rotating speed of buncher adjustable rollers.Cylinder is built with " S " type scraping blade (10).
Vavuum pump (1) is driven by precision digital pressure switch (9) setting vacuum, by vacuum-pumping tube, setting vacuum is evacuated to vacuum chamber, then carry out microwave drying, vacuum chamber top is equipped with microwave magnetron (8) and is regulated microwave power by microwave controller.Aqueous vapor in vacuum cavity is discharged in time by vavuum pump and draining valve.
Claims (1)
1. a drum-type drying equipment in microwave vacuum case, is characterized in that cylinder (11) is contained in microwave vacuum case (7), drives dry materials; Supported by rolling wheel support (5) bottom drum front end, drum rear wall central authorities connect sealed rotation shaft (12), sealed rotation shaft is fastening by two ends sealing flange, separately there is silicone rubber for sealing circle centre, rear end connection for transmission chain (14), drive (16) and variable-speed motor (15); And control the vacuum in microwave vacuum case by high accuracy number pressure switch (9), when vacuum is higher than setting value, vacuum pumping pump shuts down automatically, when low vacuum in microwave vacuum case is in the value set, vavuum pump starts running rapidly automatically, remains in the scope of setting to make the vacuum in microwave vacuum case.
