Abstract

The utility model relates to an oblate inner heating pipe double-cone vacuum drying machine which belongs to the technical field of heat exchange. The oblate inner heating pipe double-cone vacuum drying machine is used for indirectly heating and performing vacuum drying on filter cake of medicine and chemical product. The oblate inner heating pipe double-cone vacuum drying machine is composed of the following components: a steam inlet, a condensed water outlet, double cones, oblate inner heating pipes, a left (right) rotating shaft, a left (right) bearing support, a vacuum sealing member, a tail gas filter, a driving machine, etc. The driving machine drives the double cones to rotate in a same direction. A plurality of oblate inner heating pipes are directly welded on the double cones at two sides of a man hole at a rotation center of the drying machine, and are communicated with a heating jacket. The compression resistance of each oblate pipe is far larger than that of a flat plate. Therefore inner reinforcing structure treatment of welding is not required, and trouble for welding quality of the inner reinforcing structure can be prevented. The oblate inner heating pipe double-cone vacuum drying machine further has the following advantages: simple structure, saved labor, saved powder, and reduced treatment cost. After the oblate inner heating pipes are equipped, the heating area of the double-cone vacuum drying machine is increased for 1-2 times. Therefore one set of the oblate inner heating pipe double-cone vacuum drying machine is equivalent with 2-3 sets of traditional double-cone vacuum drying machines.

Description

Heating tube bipyramid vacuum drier in oblate

Affiliated technical field

The utility model relates to a kind of oblate interior heating tube bipyramid vacuum drier, belongs to the medication chemistry technical field of heat exchange, supplies sticking wall sex medicine of various nothings and fine chemical product filter cake to carry out the dynamic vacuum drying.

Background technology

Tradition bipyramid vacuum drier leans on the very thick bicone internal surface area heating of wall thickness; Because the bicone internal surface area becomes quadratic relation with the diameter of equipment; Its volume then becomes cube relation, enlarged can make too great disparity and the difficult actual employing of ratio of volume and the area of equipment with the diameter of equipment.If interior heating is the most desirable measure that this indirect heated component heating surface (area) (HS is amplified.Traditional drying equipment adopts hollow heated plate to make interior heater; Because of the big reason thin of heating surface (area) (HS with requiring slab-thickness, must in flat board, establish pillar plug welding strengthening measure, to establish thousands of pillar plug weldings in many flat boards in the large-sized drying machines; Because plate is thin; Be difficult to the bevel for welding of consent on the thousands of flat boards is processed very standard,, expose the quality problems of welding more easily again because of the face of weld in the medicine drying machine requires sanding and polishing; As long as there is a problems of welded quality in the thousands of plug welding hard point, will cause whole drying machine paralysis.

Summary of the invention

The utility model purpose is for the amplification that overcomes bipyramid vacuum drier heating surface (area) (HS and eradicates because of area amplifies and establish the quality problems that interior strengthening measure is brought, a kind of oblate interior heating tube bipyramid vacuum drier is provided.Technical scheme of the present invention is: it is made up of steam inlet, steam condensation water outlet, steam swivel joint, a left side (right side) bearing block, a left side (right side) rotating shaft, external jacket, bicone, manhole, oblate interior heating tube, tail vapour filter, vacuum seal, drive sprocket, driving machine, exhaust tube, bleeding point etc.Its feature is: external jacket and bicone welding constitute one; A left side (right side) is revolved axle one end and is fixed in the spin balancing of bicone in the heart; A left side (right side) rotating shaft is bearing on the bearing block of a left side (right side); Drive sprocket is located on the dextral shaft, and driving machine drives drive sprocket and drives bicone and rotates to a direction; Many oblate interior heating tubes equidistantly are arranged in drying machine pivot both sides; The long axis direction of oblate tube section is perpendicular to rotating shaft; Leave the maintenance flushing channel that is equivalent to the manhole diameter width between the both sides; The heating tube two ends are passed and directly are welded on the bicone in oblate, establish the gap of cleaning between the oblate interior heating tube; Primary steam and steam condensation water are through steam swivel joint input (going out) heating jacket, and vacuum exhaust pipe passes vacuum seal and gets in the bicone, establishes exhaust gas filter at its end, and tail gas is discharged through bleeding point.

The oblate interior heating tube compressive resistance of the equal wall thickness of cause is much larger than the hollow heated plate of equal wall thickness; Do not strengthen structure so need not establish welding in oblate in the heating tube; Employing need not welded the oblate interior heating tube bipyramid vacuum drier after the reinforcement structure; Just do not exist welding to strengthen the trouble and worry of architecture quality problem, oblate interior heating tube directly is welded on the bicone, and saving labor helps reducing equipment cost; Dried material contacting and reducing flow resistance during oblate interior heating tube shape helped and rotation is flowed; Structure is simplified the cleaning that also helps equipment significantly, establish oblate in behind the heating tube heating surface (area) (HS of bipyramid vacuum drier can increase by 1～2 times, one can be supported 2～3 traditional bipyramid vacuum driers.
