Abstract

The invention relates to a single-cone vacuum drying machine which belongs to the technical field of heat exchange and is used for 30-160 DEG C heating and vacuum drying of medicine and chemical engineering products and recovery of organic solvents. The single-cone vacuum drying machine comprises an inner barrel body, a steam heating jacket, a left (right) bearing seat, a left (right) rotating shaft, an inner heating member, a driving chain wheel, a driving machine and the like, wherein one end of the inner barrel body is an elliptical sealing head, and the other end of the inner barrel body is a cone-shaped body, so that the products can be fast and completely unloaded, and volume and the inner heating area also can be increased; the two ends of the heating jacket are better-stressed elliptical sealing heads; saturated steam is adopted for replacing the traditional hot-water heating; the inner heating member is formed by welding thin-wall flat pipes with better inner-pressure stressing and two acute-angled sides; and after the inner heating member is arranged, the total heating area of the drying machine is increased by 3-4 times than that of the traditional double-cone vacuum drying machine. As the thickness of the wall of the flat pipe is 1/4-1/2 of that of one cone body, the production efficiency of one single-cone vacuum drying machine can be equivalent to that of 2-3 traditional double-cone vacuum drying machines; and therefore, the investment can be saved and lots of power consumption and stainless steels are also 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, supply sticking wall sex medicine of various nothings and chemical products to carry out 30～160 ℃ of heating, vacuum dryings.

Background technology

There is the structure large-scale problem in tradition bipyramid vacuum drier; Be far smaller than the exaggerated scale of bicone volume because of the exaggerated scale of the back bicone outer wall heating surface (area) (HS that maximizes; And the bipyramid vacuum drier of dependence heating surface (area) (HS heat drying, maximization can not reach the key purpose that heating surface (area) (HS maximizes.The patent No.: 200720199358.Heating, vacuum drying machine in 7 pairs of temperature is employed in and establishes heating plate in the thin type hollow in the bicone, has solved the purpose that bipyramid vacuum drier dry heat area maximizes.But heating plate receives internal pressure in the large tracts of land thin type hollow, must make structural strengthening.Motherboard punching carrying out plug welding is adopted in the tradition reinforcement, because the face of weld of medicine machine equipment must polish polishing, makes the plug welding quality very unreliable.The patent No. 200820154931.Though the 7 harmless structure heating plate technology mother metals of strengthening can not punch; But in a large tracts of land, weld hundreds and thousands of strengthening parts in the middle of the heating plate; And to guarantee that each pad welding quality is perfectly safe; As long as a pad quality has problem, the explosion of a point will influence the success or failure of entire plate and whole drying machine.

Summary of the invention

Heater did not need a kind of single awl vacuum drier of reinforcement in the object of the invention provided, and technical scheme of the present invention is: it by steam inlet, steam condensation water outlet, steam swivel joint, left shaft holder, left-handed rotating shaft, Steam Heating chuck, inner barrel, manhole, weld interior heater, tail gas filtering plate, tail gas exhaust tube, right bearing seat, dextral shaft, drive sprocket, driving machine, exhaust tube holder and the bleeding point etc. that constitute by the flat pipe and form.Be characterized in: inner barrel one end is that bullet constitutes for the ellipsoidal head other end; Steam Heating chuck two ends are welded by ellipsoidal head entirely; Establish heater in the polylith in the inner barrel; Left and right rotating shaft is fixed on cylindrical shell spin balancing center, and left and right rotating shaft is bearing on the left and right bearing block, 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 manhole up and down and make the maintenance flushing channel; Establish the interior heater of polylith perpendicular to the maintenance flushing channel in maintenance flushing channel both sides, steam and steam condensation water are by the steam condensation water UNICOM mouth and the Steam Heating chuck welding UNICOM and fixing at interior heater two ends; Pass dextral shaft by the fixing tail gas exhaust tube of exhaust tube holder and get into inner barrel, get into inner barrel and establish the tail gas filtering plate parallel with interior heater 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 pass left-handed rotating shaft devaporation heating jacket, pass after the left-handed rotating shaft outlet of the steam condensation water on the steam swivel joint again from the steam condensation water of Steam Heating chuck and discharge.

Inner barrel is an employing bullet only; And an end adopts stressed normal ellipsoidal head preferably; Can take into account the heating surface (area) (HS of the volume and the interior heater of inner barrel; Neat and tidy characteristics when not losing bullet again and unloading dry products, the Steam Heating chuck is complete to adopt stressed good normal ellipsoidal head, and the wall thickness that helps the attenuate chuck is used material with saving.

Interior heater is made up of the flat pipe welding of thin-walled; The flat pipe has bigger specific area; The flat pipe can bear the internal pressure more much bigger than the large-area flat-plate of same wall thickness; So no longer need establish the reinforcement and the suitable wall thickness of attenuate flat pipe in the flat pipe, help reducing thermal resistance and reduction equipment manufacturing cost.
