A kind of Multi-layer vibration dryer
Technical field
The utility model is a kind of Multi-layer vibration dryer, is applicable to the technical field of drying of Powdered, graininess, bulk, the material such as spherical, is applicable to the technical field of drying of the solid material of the industries such as chemical industry, food, medical treatment.
Background technology
Be dried in the production process of the industries such as chemical industry, food, medical treatment and usually relate to; and be very important operation; be not only Separation of Solid and Liquid process, last procedure of usually still producing, the quality of product depends on the comprehensive condition that dry technology and equipment use to a great extent.Consider from economic angle, drier is expensive, and construction investment is larger.On the other hand, dry is again highly energy-consuming process, and the thermal efficiency fluctuates in a big way, and the running expense of equipment and the design selection of drier have very close relationship, so the policymaker of enterprise always relatively payes attention to this.The kind of material of being dried has many, and their physicochemical property has again very big-difference.The production technology that even same kind is different, the product requirement that same kind is different, cause drying condition all to have any different, so just determined the complexity of dry engineering.As can be seen here, dry run has higher technical compared with other unit operations.
For being dried of solid material, the domestic extensive drying equipment using now comprises normal pressure baking, drying under reduced pressure, fluidized drying, pneumatic conveying drying etc., and wherein first two drying equipment energy consumption is large, and the thermal efficiency is low, causes environmental pollution simultaneously; Although latter two equipment is improved in energy consumption and thermal efficiency utilization, it uses and is mainly limited to solid particle, seems helpless for the dry of material such as block, spherical.In addition, that solid material dry also can adopt is infrared, microwave, the modern advanced drying equipment such as freezing, but the drawbacks limit such as energy consumption is high, expensive, maintenance cost is high the use of these equipment.
For solving the problems such as energy consumption, the thermal efficiency, cost and environmental pollution, there is in recent years a series of improving equipment.For example, improved multicompartment fluidized bed, vibrated fluidized bed etc.In recent years also occurred more multi-layer vibration drying equipment, basic device is all box-type drying structure, inner placement of multiple layers basin, and heat supply in case, places vibrating motor for vibration in bottom.In these equipment, basin mainly contains spirality, circle, taper, stairstepping and swash plate etc.Heat-supplying mode is mainly divided in case two kinds of heating and case air-flow heat supply outward, in case, heating is top or the lower part equipment heater at drying box, the outer air-flow heat supply of case is from top or bottom is blown into hot-air or steam in drying box, how equipment arranges inner core in drying box is moved for hot gas, equipment component arranges opening for heating at inner core and each dish junction, also there is a small amount of equipment not establish inner core and directly in drying box bottom or top, air inlet is set, in addition, also there is equipment that the device of chuck heat supply is set in basin bottom.
Reduced energy consumption although improve fluid unit, improved the thermal efficiency, its limitation does not improve, and device structure complexity, does not utilize maintenance simultaneously.Multi-layer vibration drying equipment moves material and hot blast simultaneously, has reduced energy consumption, has improved the thermal efficiency, and usage range is also relatively extensive, but existing drying equipment exists some problems.First, basin shape is single, for circular basin, material only moves under the effect of vibration force, though can keep growing run duration, reaches good drying effect, but long the dry of heat sensitive material that be unfavorable for of heat time, also drying efficiency also can not get improving simultaneously; For basins such as spirality, taper, stairsteppings, material moves downward under the double action of vibration force and gravity, though can improve drying efficiency, run duration is relatively short, and material may can not get fully dry.Secondly, hot blast opening is to be improved, and the basin hot blast opening of the said equipment is too simple, because hot blast is to supply with whole casing to be dried, this certainly will, by reducing drying efficiency, also can make partial material fall from hot-air channel simultaneously, occurs the phenomenons such as uneven drying is even.
In sum, obviously there is the shortcomings such as energy consumption is large, the thermal efficiency is low, environmental pollution is serious in the solid drying equipment of present industrial extensive use, and the application of fluidized drying and pneumatic conveying drying is limited by material, and New drying equipment is expensive.Meanwhile, carry out for above-mentioned reasons improved serial drying equipment, still have the series of problems such as basin shape is single, hot blast opening is to be improved.
The patent No. is ZL 2,011 2 0365120.3, name is called in the Chinese utility model patent of " Multilayer countercurrent vibrating dryer " and discloses a kind of Multilayer countercurrent vibrating dryer, comprise cabinet, support, vibrating motor, cabinet is arranged on support, vibrating motor is arranged in support, cabinet is core structure, charging aperture, exhaust outlet is on top, discharging opening, hot blast import is in bottom, in cabinet, interlaced arrangement has circle, taper basin, circular basin feed opening is arranged on edge, the feed opening of taper basin is arranged on center, in basin, be uniformly distributed the moving sieve aperture of heat supply fate.Simple in structure, be easy to safeguard, reliable, be suitable for various materials, dry mass is good, has good drying efficiency and the thermal efficiency, consumes energy low, can carry out continuous, low temperature drying.But, due in pharmaceutical production, because GMP has requirement to air purity, this equipment can only integral installation at clean area, collect folk songs at clean area, can greatly affect like this air quantity, the blast of clean area, destroy clean area environment, increase clean area energy consumption; Because equipment only has air blast, device interior blast is larger, and heat loss is serious, and energy consumption increases; Blast pipe and discharge pipe show without temperature, wind speed, are not easy to production operation, therefore, are necessary to develop in fact a kind of multi-layer vibration drying equipment that is applicable to medicine clean area production and application.
