Abstract

The invention relates to a vacuum glassed steel drier and belongs to the technical field of heat exchange. The vacuum glassed steel drier is used for vacuum drying of chemical medicine products containing highly corrosive media and is composed of a steam rotary connector, a left rotary shaft, a right rotary shaft, a driving chain wheel, a driver, a heating jacket, a heating and evaporating coiled tube, a glassed steel hollow corrugation inner heating component serving as an inner cylinder, a filter, a rotary vacuum sealing part and the like, wherein the left rotary shaft and the right rotary shaft are fixed on the two diagonal lines of an end socket of the heating jacket respectively and pitch up by 20 degrees from left to right, and the driver drives the driving chain wheel fixed on the left rotary shaft to rotate in one direction to achieve a mixed function of radial rotation and axial reversing. Low-temperature saturated steam is adopted as a heat source for heating and drying, the tail gas filter and the rotary vacuum sealing part are connected in series, solid pollutants contained in leaked gas generated from the leaked sealing part can only be sucked into the filter instead of being in contact with the medicine being dried, and then medicine quality is guaranteed.

Description

Enamel vacuum drier

Technical field

The present invention relates to a kind of enamel vacuum drier, belong to technical field of heat exchange, for the various chemical and medicine industry product vacuum drying containing high corrosion medium.

Background technology

Tradition glass lining double conic vacuum drier only relies on the enamel inner barrel heat drying that heating surface (area) (HS is very little, drying efficiency is very low, difficulty meets the needs of production development, can only produce with many same drying machine parallel operations, for many years always in so greatly waste of manpower, material resources and energy consumption.

Summary of the invention

The present invention is the shortcoming that overcomes existing traditional glass lining double conic vacuum drier, and a kind of enamel vacuum drier of establishing interior heater is provided.Technical scheme of the present invention is: it is by heating steam import, steam swivel joint, solidifying water out, left shaft holder, left-handed rotating shaft, drive sprocket, driving machine, left-handed rotating shaft steam condensation water interface, heating jacket steam condensation water interface, heating jacket, heating evaporation coil pipe, enamel end socket, the manhole feed inlet and outlet of holding concurrently, tail gas connects the mouth of pipe, the hollow ripple heating plate of enamel member, filter, dextral shaft tail gas connects the mouth of pipe, right bearing seat, vacuum exhaust pipe, dextral shaft, rotation vacuum seal, tail gas is extracted the compositions such as mouth out.Its feature is: in the enamel consisting of the hollow ripple heating plate of polylith enamel, the welding of the enamel end socket at heater and two ends is integrally formed, the end socket of drying machine forms an entirety with heating jacket welding again, left and right rotating shaft is fixed in two diagonal positions of heating jacket end socket, and the 20 ° of angles of facing upward from left to right, guarantee that exhaust gas filter position is more than material level, left-right rotary rotating shaft is placed in Y-axis bearing, and driving machine drives and is fixed on the drive sprocket in left-handed rotating shaft and drives drying machine to a direction rotation; On heating jacket inwall, fix heating evaporation coil pipe, and in heating jacket preset pure water, steam condensation water interface on steam inlet and left-handed rotating shaft and the heating jacket of heating steam on steam swivel joint enters heating evaporation coil pipe, heating evaporation pure water produces≤100 ℃ of desiccant saturated vapor thermals source, and the solidifying water out that the steam condensation water in heating evaporation coil pipe enters on steam condensation water interface and the steam swivel joint in rotating shaft on heating jacket and left-handed is discharged; Filter connects the mouth of pipe by tail gas and is fixed on position more than the highest material, and tail gas connects the mouth of pipe through tail gas and is connected mouth of pipe connection with the dextral shaft tail gas on dextral shaft, and the bleeding point of last tail gas in vacuum exhaust pipe and rotation vacuum seal discharged; Wet stock and dry products are all via doubling as the manhole input of input and output material or discharging.

The hollow ripple heating plate of enamel be to follow glass-lined equipment structure principle, integral surface is continuous circular arc shape ripple, THS is long-pending is to be equivalent to many times of inner barrel internal surface area, so make to establish the drying machine drying efficiency after heater in enamel, also expand many times, making a drying machine be equivalent to tradition does not have many times of interior heater drying machine, naturally makes the cost performance of drying machine significantly promote.The vacuum seal of drying machine is arranged and is different from traditional double-cone vacuum dryer, vacuum seal is shifted out outside drying machine, while guaranteeing vacuum seal because of wearing and tearing gas leakage, gas leakage is carried various wearing and tearing secretly and is polluted foreign matters and can only fall into filter inner side and can not pollute dry products, avoids medicine contaminated and cause and produce adverse drug reaction.Drying machine is used low temperature saturated vapor instead and is substituted the inefficient hot water heating of tradition, is conducive to improve dry heat temperature difference and improves dry efficiency.
