Problems solved by technology

[0003] Also, the double-cone vacuum dryer is the main drying equipment for many raw materials at present, but the vacuum seals in the existing traditional double-cone vacuum dryer have structural pollution risks
The vacuum seal in the dryer is operated under the condition of dryness, dust and no lubricant for a long time, and the sealing ring in the seal will inevitably be worn and damaged. Because of the v

Abstract

The invention relates to a d double-cone vacuum drier with a narrow-wedge internal heating plate, belonging to the field of a pharmaceutical chemical heat exchange technology and aiming at carrying out dynamic vacuum low-temperature drying meeting GMP standard requirements on pharmaceutical and fine chemical product filter cakes. The double-cone vacuum drier with the narrow-wedge internal heating plate comprises a double-cone body, a low-temperature saturated vapor generator, a vapor heating jacket, a left (right) rotating shaft, a left (right) bearing seat, a narrow-wedge internal heating plate, a filter, a hidden hazard free vacuum sealing piece, a driving machine and an exhaust pipe, wherein the low-temperature saturated vapor generator supplies a low-temperature saturated vapor heat source of 30-100-DEG C for vacuum drying; the heating area of the double-cone drier with the narrow-wedge internal heating plate is 2-3 times that of the traditional double-cone drier; and the wall thickness of the internal heating plate is one fourth-one third that of the double-cone body, heat resistance is low and the equipment weight is greatly reduced, thus the manufacturing cost of the drier is greatly lowered while improving the efficiency of the drier; and the hidden hazard free vacuum sealing piece has no structure pollution hazard of the traditional sealing piece, thus the drier truly meets the GMP standard requirements.

Description

Technical field [0001] The invention relates to a double-cone vacuum dryer with a narrow wedge-shaped inner heating plate, which belongs to the technical field of heat exchange in medicine and chemical industry, and is used for dynamic vacuum low-temperature drying of various non-adhesive medicine and fine chemical filter cakes that meet the requirements of GMP regulations. Background technique [0002] The existing traditional double-cone vacuum dryer is heated by the surface area of ​​the double cone. Since the surface area of ​​the equipment cylinder has a quadratic relationship with the diameter of the equipment, and the volume of the equipment has a cubic relationship with the diameter of the equipment, expanding the diameter will increase the volume and area. The expansion ratio is too disparate to be practically adopted. Setting the inner heating plate is the most desirable measure to enlarge the heating area of ​​the equipment. Due to the wide width of the straight ...
