Abstract
The utility model discloses a double-cone rotary vacuum drying machine which comprises a drying tank. The drying tank comprises a drying tank casing, a drying chamber arranged in the drying tank casing and a drying tank clamp sleeve arranged between the drying tank casing and the drying chamber, and the double-cone rotary vacuum drying machine further comprises a heating device used for providing a heat conducting medium for the drying tank clamp sleeve, a drawing device used for drawing water vapor in the drying chamber and a nitrogen cylinder communicated with the drying chamber through a stainless steel ball valve. The double-cone rotary vacuum drying machine avoids secondary damping of a material caused by the fact that the material absorbs air with heavy moisture or residue moisture in a pipeline at high temperature after the material is dried in vacuum back-to-zero mode. During discharging, the material is cooled for a period of time by feeding nitrogen to be contacted with air at low temperature, so that degree of oxidation of the material is effectively controlled.
Description
Technical field
The utility model relates to the vacuum drying field, is specifically related to a kind of double conic rotary vacuum dryer, is applicable to the drying of material that aridity and oxidizability are had relatively high expectations.
Background technology
Double conic rotary vacuum dryer is widely used in the combination drying of the materials such as powder or granule of the industries such as medicine, food, chemical industry as the New Dryer that integrates mixing-drying.
The vacuum drying principle is for to pass into heat energy (such as hot water, low-pressure steam or conduction oil) in airtight interlayer, heat is passed to the material that is dried through inner casing.Under power drive, tank body is made slow circumvolve, and material constantly mixes in the tank, strengthens dry purpose thereby reach.Material is in vacuum state, and vapour pressure decline makes the moisture content (solvent) on material surface reach capacity state and evaporated, and in time discharges recovery by vavuum pump.The moisture content of material inside (solvent) constantly to surface infiltration, evaporation, discharge, constantly carry out by three processes, and material reaches drying purpose within very short time.
But this equipment is complete in drying in the prior art, sees in easily part steam or the globule when vacuum returns zero in the stove, causes material again moist; Material also keeps higher temperature (about 70 ℃) when coming out of the stove, and it is not enough to control on the material of degree of oxidation protection for some.
The utility model content
The purpose of this utility model is the problems referred to above that are for the prior art existence, a kind of double conic rotary vacuum dryer is provided, simple in structure, easy to operate, thereby material sucks moisture remaining in the very heavy air of moisture or the pipeline and causes material secondary humidity when avoiding dry complete final vacuum to return zero in the time of higher temperature, effectively controls the degree of oxidation of material.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions:
A kind of double conic rotary vacuum dryer, comprise drying chamber, drying chamber comprises the drying chamber shell, be arranged on the hothouse in the drying chamber shell and be arranged on drying chamber chuck between drying chamber shell and the hothouse, also comprises for the heater of heat-transfer working medium being provided to the drying chamber chuck and being used for extracting the draw-out device of the water vapour in the hothouse.
Aforesaid heater comprises heating cabinet, and heating cabinet provides heat-transfer working medium by circulating pump for the drying chamber chuck.
Aforesaid draw-out device comprises water ring vacuum pump and condensation water tank, water ring vacuum pump comprises air entry, exhaust outlet and water inlet, the air entry of water ring vacuum pump is communicated with hothouse by stop valve, the water inlet of water ring vacuum pump is communicated with condensation water tank by water intaking valve, and the exhaust outlet of water ring vacuum pump is communicated with condensation water tank.
Also be provided with between the exhaust outlet of aforesaid water ring vacuum pump and the condensation water tank and let out vacuum valve.
A kind of double conic rotary vacuum dryer also comprises nitrogen cylinder, and nitrogen cylinder is communicated with hothouse by a stainless steel ball valve.
The utility model compared with prior art has the following advantages:
Thereby material sucks moisture remaining in the very heavy air of moisture or the pipeline and causes material secondary humidity when 1, avoiding dry complete final vacuum to return zero in the time of higher temperature;
2, in discharging, utilize and pass into nitrogen cooling a period of time, the ingress of air so that material is come out of the stove in the time of lower temperature, thus effectively control the degree of oxidation of material.
