Description of drawings
For the content that makes the utility model is more clearly understood, below basis specific embodiment and combine accompanying drawing, the utility model is done further detailed explanation, wherein
Fig. 1 is the structural representation of the mud of the utility model with drying machine;
Fig. 2 is the cross-sectional view of the mud of Fig. 1 with drying machine.
Embodiment
See Fig. 1,2, the mud of present embodiment comprises with drying machine: be suitable for through chuck heating housing 1, axially be located at many groomed oar rachises 2 in the housing 1, be distributed in a plurality of wedge type paddles 3 on this groomed oar rachis 2; The end of said groomed oar rachis 2 links to each other with heat-transfer medium transfer lime 4 through swivel joint; The end of said groomed oar rachis 2 is in transmission connection through a step-down gear 6 and a driving motor 5.
The bottom section of said housing 1 is the W type.
The top of contiguous said housing 1 front end is provided with a plurality of charging openings 11, and the bottom of contiguous said housing 1 rear end is provided with discharge port 12, and the top of contiguous said housing 1 rear end is provided with cleanout opening 13, and contiguous said housing 1 central top is provided with moisture exhausting port 14.
The mud of present embodiment is with the products characteristics of drying machine:
Because indirect heating is not carried air in a large number and taken away heat, HU can reach 80%-90%.The moisture eliminator outer wall is provided with thermal insulation layer again, and to pasty material, evaporation 1KG water only needs 1.2KG water vapour.
Compact equipment, the plant area area is little.Can know that by device structure dry institute heat requirement mainly is to be provided by the many hollow blade walls that are arranged in thick and fast on the tubular shaft, and the heat transfer capacity of chuck wall only accounts for few part.Have huge heat-transfer surface in the unit useful volume, just shortened the treatment time, equipment size diminishes.Floor area of building and space have just greatly been reduced.
Use different thermal mediums, both can handle heat-sensitive material, can handle the material that needs pyroprocessing again.Typical media has: water vapour, thermal oil, hot water, water coolant etc.But but both also off-line operations of operate continuously can understood the field application very much.
Gas usage is few, can reduce or save the part utility appliance accordingly.Owing to do not need to heat, therefore greatly reduced gas usage in the drying process with gas.Adopt wedge shape oar blade type moisture eliminator only to need little of gas to be used to carry and evaporate to wet and divide.Gas usage seldom need only satisfy under the drying operation temperature condition, the noncondensing dew of dehumidification system.
Because gas usage is few, gas flow rate is low in the moisture eliminator, and the dust of being carried under one's arms out by gas is few, and it is convenient that the fuel gas and dust of dry back system reclaims, and can dwindle the cyclonic separator size, saves or dwindles sack cleaner.Gas heater, scales such as gas blower all can be dwindled, and save facility investment.
This equipment normal running, only 1 hour/day/people.Stirring at low speed and rational structure.Abrasion loss is little, and maintenance cost is very low.
Because the special compression of wedge type paddle--expansion stirring action, material particles is fully contacted with heat-transfer surface, between axial area in, material temperature, humidity, mixedness gradient are very little, thereby have guaranteed the stability of technology.
The material wide adaptability, product drying is even.Establish overflow weir in the moisture eliminator, can regulate material lagging amount in the moisture eliminator according to material properties and drying conditions.Can make the interior material lagging amount of moisture eliminator reach cylindrical shell volumetrical 70%-80%, increase the residence time of material, to adapt to the dry requirement of difficult dried material and high moisture material.In addition, also the rotating speed of adjustable feed rate, axle and thermal barrier temperature etc. are being planted and arbitrarily selected residence time of material between several hours somewhat.Therefore all be suitable for for being prone to dry and being difficult for dried material.Moisture content has only 0.1%, existing examples of industrial application.In addition, though in the moisture eliminator many agitating vanes are arranged, mixing of materials is even, and still, material flows to the mobile piston flow that is basically of discharge port from charging opening in moisture eliminator, residence time narrowly distributing, and product drying is even.
Be applicable to multiple drying operation.Before addressed wedge shape oar blade type drying and can regulate the drying process condition through several different methods, and its operation easy to control than fluidised bed drying, air stream drying is so be applicable to multiple operation.
Because the automatic cleaning action of paddle can be handled viscosity rerum natura, plaster material.The wedge shape blade has self-purification capacity, can improve the blade heat transfer effect.The dispersion force that associated reaction produced of the scarp of revolving vane and particle or powder bed makes the material that is attached on the heating inclined-plane be easy to automatically remove, and makes blade keep heat transmission function efficiently.In addition, because the reverse rotation of diaxon blade, the material on alternately segmentation compression (on diaxon blade inclined-plane at a distance of recently the time) and when furthest (at the diaxon paddle face) inclined-plane that expands makes near the material of heat-transfer surface stirred by fierceness, has improved heat-transfer effect.Wedge type oar blade type agitator drier heat transfer coefficient is higher.
Obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not to be qualification to the embodiment of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation that these spirit that belong to the utility model are extended out or change still are among the protection domain of the utility model.
