Embodiment

[0042] Such as figure 1 The shown vacuum dryer with cooling section consists of drying chamber (1) with cooling section, hopper (2), unloading device (3), elbow (4), air duct (5), vacuum unit ( 6), bracket (7), driving device (8), heating device (9) and track (10).

[0043] Such as figure 2 The shown drying chamber (1) with cooling section is a patent applied by myself; the drying chamber (1) with cooling section is composed of outer shell (12), inner chamber (13), heat-conducting working medium (15) and safety valve (16 )composition.

[0044] The shell (12) is outside the inner chamber (13), and there is a heat-conducting working medium (16) in the cavity between the outer shell (12) and the inner chamber (13).

[0045] The end of the inner compartment (13) with the shell (12) is a drying section; the end of the inner compartment (13) without the shell (12) is a cooling section.

[0046] There are 2 safety valves (16) on the described casing (12).

[0047] The outside o...

Abstract

The invention discloses a vacuum drying machine with a cooling section. The vacuum drying machine is composed of a drying bin with the cooling section, a hopper, a discharge device, an elbow, a gas guide pipe, a support, a vacuum unit, a heating device, a driving device and rails. The drying bin with the cooling section is composed of a shell, an inner bin, a heat conduction medium and a safety valve. The support supports a feed port and a discharge port of the two ends of the inner bin. The vacuum unit sucks gas in a bin body of the inner bin through a gas guide pipe. In the material drying process, the drying bin with the cooling section can be rotated on the support through the driving device, cooling vertical pipes arrayed spirally have functions of stirring and propelling materials, no dead corners exist during material drying, materials are not prone to caking when dried in the drying section of the inner bin, material drying time is shortened, material drying quality is uniform, dried materials are cooled in the cooling section, material drying efficiency is improved, the material drying effect is optimized, and green, energy-saving and environment-friendly drying is achieved.

Description

technical field [0001] The invention relates to a dryer, in particular to a vacuum dryer with a cooling section. Background technique [0002] Vacuum drying equipment for materials such as grain, chemical products, coal, gravel, sand, mineral products, pasture, crops, and local specialties on the market. The material vacuum drying equipment performs vacuum low-temperature drying on materials under negative pressure and vacuum state, which solves the problem of The hot air temperature is high, and the quality of the material is poor after drying; the heating of the vacuum drying of the material on the market now is to dissipate heat through metal exhaust pipes placed in parallel, the heat conduction and heat dissipation efficiency is low, the exhaust efficiency is low, and the vacuum degree is not well controlled. As the water vaporization temperature rises, the heat energy required for drying will increase a lot, and the waste heat will not be utilized; the dried material ha...
