Problems solved by technology

[0010] However, when stirring the domestic waste put into the rotary drum with the stirring blade, the domestic waste may be involved or entangled with the stirring blade, resulting in failure to operate, or when the moisture content decreases during the drying process of the domestic waste, Since the sliding resistance of the stirring blade increases, it is necessary to predict a large amount of stirring power, etc.
[0011] In addition, the heating method is also an indirect heating method in which the heater is used to increase the temperature of the atmosphere in the box accommodated in the rotating bucket, so the heat cannot be sufficiently transferred to the domestic waste, and the thermal efficiency is poor.
Therefore, in order to heat domestic waste, more heating energy is required

Abstract

The invention relates to a vacuum drying apparatus of domestic garbage that is an apparatus for vacuum drying of domestic garbage by rotary barrel, and is also an apparatus for improving reducing of stirring power and thermoconductivity by a heater installed on a stirring vane. The apparatus has: an input and output opening (2) of domestic garbage installed at one side, the rotary barrel (1) rotatably supporting the center at the other side by a rotary joint (3) connected with a vacuum air pump (P); the stirring vane (5) installed at the internal wall of the rotary barrel and provided with the heater (4); and a vacuum absorption mechanism (7) having an absorption port (6) usually stressed by an upper coercive power pointing the upper part of the rotary barrel.

Description

technical field [0001] The present invention relates to a vacuum drying device for domestic waste, which is a device for putting domestic waste into a rotating bucket and stirring it while performing vacuum drying. The heater is a device that improves the reduction of stirring power and thermal conductivity to reduce heating energy. Background technique [0002] In the past, when carrying out the drying of domestic garbage, there are known normal pressure drying devices and vacuum drying devices. Among them, the normal pressure drying device is a device for drying domestic waste by spraying hot air under atmospheric pressure. A device for evaporating and drying household waste at low temperature under vacuum. [0003] In the case of reusing domestic waste as feed, it is undesirable to cause changes in properties when drying domestic waste at a high temperature, so there is a problem of reduced-pressure drying such as vacuum drying. [0004] A domestic waste treatment devic...
