Abstract

The invention relates to a single cone vacuum drier, which belongs to the technical field of heat exchange. The single cone vacuum drier is used for vacuum drying thermally sensitive medicines and organic solvent chemical products and recovering the organic solvent and comprises an inner cylinder body, a steam heating jacket, a left rotating shaft, a right rotating shaft, a left bearing block, a right bearing block, an inner heating plate, a driving chain wheel, a driver and the like, wherein one end of the inner cylinder body adopts a standard elliptical end socket; the other end of the inner cylinder body adopts a conical body; for efficiency of a product in drying and the increase of the number of inner heating plates, the standard elliptical end sockets are respectively arranged at two ends of the steam heating jacket; the system is heated by using 40-100 low-temperature saturated water steam instead of traditional hot water; the inner heating plates are arranged, so that the total heating area of the drier is increased by 2-4 times compared with that of a traditional dual cone vacuum dryer; the thickness of stainless steel of each inner heating plate is only 1/4-1/2 of the thickness of the cone; and one single cone vacuum drier can be equivalent to a traditional dual cone vacuum dryer, thus the drying efficiency can be multiply improved and the consumption of the stainless steel and power consumption can be greatly saved.

Description

Single awl vacuum drier

Technical field

The present invention relates to a kind of single awl vacuum drier, belong to technical field of heat exchange, be applicable to the vacuum drying of medication chemistry product and recovery organic solvent that have thermal sensitivity and contain organic solvent.

Background technology

The major defect that tradition bipyramid vacuum drier structurally exists is: can't reach the heat exchange area maximization purpose that needs most during maximization, the volume exaggerated scale that makes drying machine is produced thereby have a strong impact on the drying that maximizes much larger than heat exchange area; Though the bipyramid structure helps efficiently drawing off dry products, influenced the volume of drying machine; Existing traditional bipyramid adopts the hot water sensible heat heating that has the out temperature difference, and its heat transfer coefficient is both little and increased the burdensome and investment of a cover hot water apparatus.

Summary of the invention

The object of the invention provides a kind of single awl vacuum drier, and technical scheme of the present invention is: it is made up of steam inlet, steam condensation water outlet, steam swivel joint, steam condensation water house steward, left shaft holder, left-handed rotating shaft, Steam Heating chuck, inner barrel, manhole, interior heating plate, tail gas filtering plate, tail gas exhaust tube, right bearing seat, dextral shaft, drive sprocket, driving machine, exhaust tube holder and bleeding point etc.Be characterized in: inner barrel is made up of for bullet two parts for the ellipsoidal head other end an end; Steam Heating chuck two ends are made up of ellipse head entirely; Establish heating plate in the polylith thin type in the inner barrel; The left rotation and right rotation axle is fixed on the spin balancing center of cylindrical shell, and the left rotation and right rotation axle is bearing on the Y-axis bearing, and driving machine drives the sprocket wheel on the dextral shaft and promotes cylindrical shell and rotates to a direction; Establish width on rotating shaft center's line and equal people's bore dia being parallel to; And connect the back with two manholes up and down and make the maintenance flushing channel; Establish the interior heating plate of polylith perpendicular to the maintenance flushing channel in maintenance flushing channel both sides, steam and steam condensation water are through interior heating plate two ends steam condensation water UNICOM mouth and the fixing and UNICOM of Steam Heating chuck welding; The O-ring seals that is passed in dextral shaft and the dextral shaft by the fixing tail gas exhaust tube of exhaust tube holder gets into inner barrel; Get into inner barrel and establish the tail gas filtering plate parallel with interior heating plate at slightly upward bent tail gas exhaust tube end, tail gas is after the bleeding point extraction; Heating steam on the steam swivel joint steam inlet and steam condensation water house steward and pass left-handed rotating shaft devaporation heating jacket, discharge from the steam condensation water outlet that the steam condensation water of Steam Heating chuck passes on left-handed rotating shaft, steam condensation water house steward and the steam swivel joint.

One end of inner barrel adopts stressed normal ellipsoidal head preferably, and the other end then adopts bullet, can take into account the volume that increases inner barrel and the area of interior heating plate so on the one hand, the quick totally characteristics when not losing bullet again and unloading dry products.Normal ellipsoidal head is adopted at Steam Heating chuck two ends entirely.Single awl vacuum drier and traditional bipyramid vacuum drier are relatively; Efficiently unload dry products and the fine mixed function except equally having, under same inner barrel diameter condition, after maximizing, can establish more greatly more in heating plate; The thickness of heating plates only was 1/4～1/2 of inner barrel thickness in cause was a large amount of; Can practice thrift a large amount of stainless steels, the necessary water heater funnel of cancellation bipyramid in conjunction with adopting the heating of low temperature (40～100 ℃) saturated vapor, thus can reduce the equipment making cost.Single awl vacuum drier unit volume V (m after the maximization ³) institute has a heating surface (area) (HS F (m ²) the F/V value, comparable traditional bipyramid is big 2～4 times, promptly the drying efficiency of a single awl vacuum drier supports 2～4 traditional bipyramid vacuum driers, thereby saves the electric energy of 1～3 high-power driving motor.
