Single-cone dryer with single-layer progressive stirrer

Abstract

The invention discloses a single-cone dryer with a single-layer progressive stirrer. The dryer comprises a conical shell, a top cover, a bar type trap, a vacuum pump, the single-layer progressive stirrer and an air source, wherein the top cover, the bar type trap and the vacuum pump are arranged above the conical shell; the bar type trap comprises a vacuumizing tube and an air blowback tube whichis arranged with the vacuumizing tube side by side; one end of the vacuumizing tube and one end of the air blowback tube are respectively provided with a filter hood; the filter hood is wrapped by filter media; the bar type trap is installed on the top cover; the vacuumizing tube is connected with the vacuum pump; the air blowback tube is connected with the air source; an automatic diaphragm valve is arranged between the air blowback tube and the air source; the single-layer progressive stirrer is vertically arranged inside the conical shell; the single-layer progressive stirrer comprises a stirring main shaft and a stirring fulcrum shaft arranged at one end of the stirring main shaft; and the whole stirrer is in an inverted T shape. The single-cone dryer is provided with the bar type trap and the single-layer progressive stirrer and has the following beneficial effects: the filtering area is big, the efficiency is high, and the drying efficiency and effect are improved.

Description

technical field [0001] The invention relates to a drying device, in particular to a single-cone dryer with a single-layer progressive agitator. Background technique [0002] The dryer is mainly used for product purification and drying. The working principle of the dryer is: put the material to be dried into the container, then pass hot water into the jacket of the container to raise the temperature, and then vacuumize the container, because the boiling point of water rises in the vacuum state, the inside of the container The water evaporates into gas and is pumped away, so as to achieve the purpose of drying. [0003] A trap is usually installed in the dryer, and the trap is a device used to trap condensable vapor in the vacuum system. It uses the principle that certain substances have adsorption properties (physical adsorption and chemical adsorption) to capture condensable vapors, which are widely used in the pipeline between vacuum pumps and diffusion pumps (or pumped c...

AI Technical Summary

Problems solved by technology

[0004] like figure 1 As shown, at present, the commonly used dryer is a double-cone dryer 1, its two ends are conical, the container body is cylindrical, and the catcher 2 of the double-cone dryer 1 is in the container. It is inconvenient to disassemble and clean, and it is in direct contact with materials, so there is a certain risk for materials with high requirements on aseptic level. In addition, the trap 2 also has the problems of small filtration area and low efficiency

[0005] In addition, 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 when it is used.
