Description

TECHNICAL FIELD

[0001] The utility model relates to the kitchen garbage drying field especially, relate to a kind of kitchen garbage drying machine. BACKGROUND

[0002] The existing kitchen garbage processing mode is mainly through the combination of stirring and breaking and heating and dewatering or using hot air drying to reduce the moisture in solid kitchen garbage, thereby significantly reducing the volume and weight of kitchen garbage, reducing odor, while retaining part of organic matter, facilitating subsequent composting or energy utilization.

[0003] The existing kitchen garbage drying equipment, such as the invention patent with the authorized announcement No. CN106660085B, provides a miniaturized and excellent applicability reduction and volume reduction processing device and the airflow forming mechanism used by the reduction and volume reduction processing device, which can prevent the spoilage of waste and the odor during the storage of waste by contacting the heated air with the waste containing moisture for drying. At the same time, through the dewatering process, the waste can be reduced and volume-reduced. Compared with the traditional combination of stirring and breaking and heating and dewatering, the drying equipment has the following advantages: 1. The heated air is more uniform, and the dewatering effect is more significant; 2. There is no need to stir and break the solid kitchen garbage, which will not cause wear and tear of the equipment; 3. During the heating of the kitchen garbage, the inner wall of the container will not be burned and stuck, which is convenient for cleaning; 4. The filter effectively filters the evaporated moisture and odor, removes the odor, and avoids environmental pollution.

[0004] However, the existing kitchen garbage drying equipment still has some shortcomings: first, the bottom of the ordinary drying machine drum is easy to be blocked by the accumulated garbage, which causes poor drainage and difficulty for hot air to penetrate to the bottom of the kitchen garbage, resulting in low heat exchange efficiency; second, the filtered wastewater has no precise guide path after heating, and the steam flow path is chaotic and the discharge efficiency is low; third, the container for containing kitchen garbage has insufficient volume, and the single drying capacity is limited, resulting in low drying efficiency.

[0020] The beneficial effects of the technical scheme of the utility model mainly include:

[0021] 1. The high-speed airflow is formed by the fan, and the heating ring is used for rapid heating and the hot air cover is used for heat preservation and air guide. Since the upper limit of the heating temperature that can be reached by the heating ring is high, the high-speed airflow passing through the heating ring can be rapidly heated to form high-speed hot airflow blown into the inner cylinder along the axial direction. The high-temperature and high-speed hot airflow can improve the dehydration efficiency and drying effect of the kitchen waste. The high-speed hot airflow is blown into the water storage space at the bottom of the inner cylinder along the gap of the kitchen waste, and forms steam. Then the steam enters the hot air chamber again through the steam passage. The residual heat of the steam can preheat the inside of the hot air chamber, thereby improving the drying efficiency in the subsequent drying process and realizing the air internal circulation of the kitchen waste dryer.

[0022] 2. The draining grid at the bottom of the inner cylinder is provided with an upwardly protruding anti-blocking support part. When the kitchen waste is placed in the inner cylinder, the anti-blocking support part lifts the kitchen waste at the bottom, thereby avoiding the direct blocking of the kitchen waste on the surface of the draining grid and ensuring that the high-speed hot airflow can smoothly enter the water storage space to form steam. The guide groove on the outer periphery of the inner cylinder forms a plurality of downward guiding paths between the inner cylinder and the base, which can directionally transport the steam in the water storage space to the hot air chamber. At the same time, since the guide groove can provide steam output space, the width of the steam passage can be narrowed to expand the overall volume and capacity of the inner cylinder.

[0023] 3. The air in the hot air cavity is continuously extracted by the fan, so that the air pressure in the hot air cavity is lower than the external air pressure. Therefore, the steam in the steam passage will not directly discharge from the air inlet after entering the hot air cavity, but will be extracted by the fan into the hot air cover again. Since the outlet of the fan is communicated with the hot air cover, the air pressure in the hot air cover is relatively high, and two air flows are output. One air flow is heated by the heating ring and then blown to the inner cylinder through the hot air outlet. The other air flow is blown into the filtering device and then discharged from the air outlet after being filtered. The filtering device can adsorb odors and disinfect the discharged air, realizing environmental protection and hygiene during use. BRIEF DESCRIPTION OF DRAWINGS
