Single cone dryer with anchor stirrer

Abstract

The invention discloses a single cone dryer with an anchor stirrer. The single cone dryer comprises a cone shell, a stirrer, a top cover, a bar trap, a vacuum pump and a gas source; the stirrer is the anchor stirrer, the anchor stirrer comprises a stirring main shaft and a stirring fulcrum shaft, and the stirring fulcrum shaft is arranged at one end of the stirring main shaft; the bar trap comprises a vacuum pumping pipe and a gas back-blowing pipe arranged in parallel with the vacuum pumping pipe, filter hoods are arranged at one end of the vacuum pumping pipe and one end of the gas back-blowing pipe, and a filter medium is wrapped outside the filter hoods; and an automatic diaphragm valve is arranged between the gas back-blowing pipe and the gas source. The single cone dryer can shorten the drying time, obtain an agglomeration-free product with uniform quality, promote the drying efficiency and optimize the drying effect; and the trap has larger filter area and higher efficiency, is convenient to disassemble and clean, and avoids direct contact with a material.

Description

technical field [0001] The invention relates to drying equipment, in particular to a single-cone dryer with an anchor stirrer. Background technique [0002] The dryer is mainly used for the purification and drying of medicines. At present, a vacuum rotary dryer is usually used, its two ends are conical, and the body is cylindrical, also known as a double-cone dryer. The middle part of the body of the double-cone dryer is provided with a hollow suspension shaft to provide rotating support and related pipeline laying. The double-cone dryer is rotated to heat and dry the medicines and other products that need to be dried in the double-cone dryer. [0003] However, due to the huge volume of the double-cone dryer and its inherent drying method, the drying efficiency is low and the effect is poor during use, and the trap of the double-cone dryer is in the container, so it is inconvenient to disassemble and clean after each use , and in direct contact with the material, there is...

Problems solved by technology

[0003] However, due to the huge volume of the double-cone dryer and its inherent drying method, its drying efficiency is low and the effect is poor during use, and the trap of the double-cone dryer is in the container, so it is inconvenient to disassemble and clean after each use , and in direct contact with the material, there is a certain risk for the material with high requirements for aseptic level. In addition, the trap also has the problems of small filtration area and low efficiency
