TECHNICAL FIELD

The present disclosure relates to the technical field of kitchen waste treatment, and in particular, to a device for rapidly processing kitchen waste into an organic fertilizer.

BACKGROUND

Currently, the amount of kitchen waste is produced at an amazing speed every year, imposing a great pressure on kitchen waste treatment. This also means a broad market space. Poor waste treatment not only pollutes the atmosphere and groundwater, but also causes breeding of mosquitoes that spread diseases, and seriously restricts the sustainable development of cities as a major social public hazard. With the continuous improvement of people's living standards, the proportion of kitchen waste in daily domestic waste is increasing, and its composition is becoming increasingly complex. Treatment of the kitchen waste is an important link to solving the problem of domestic waste.

It is time-consuming and laborious to clean up kitchen waste. There are mainly four schemes for kitchen waste treatment in the market: landfill, incineration, composting, and biological treatment. When a disposer is used for decomposition in biological treatment, collected kitchen waste is usually directly poured into the kitchen waste disposer, and large particles in the kitchen waste are prone to remaining and need to be crushed.

All types of kitchen waste produced by means of Chinese cooking methods include soft waste such as peels, vegetables and leaves, and hard substances such as fishbones and bones, and the kitchen waste cannot be directly discharged through a sewer system. Therefore, in the past, a usual way was to first manually remove such large-volume kitchen waste in advance in operations after meals, which was cumbersome and easily made people feel uncomfortable, thereby causing great inconvenience. In view of this, there are many types of kitchen waste treatment devices on the market at present, which reduce such collection and cleaning operations by directly crushing kitchen waste and then discharging the kitchen waste, thereby bringing convenience to the public and many families and being widely liked by consumers.

The kitchen waste disposer is a modern novel environment-friendly electrical appliance, which provides a novel method for treating waste, and is mainly configured to crush waste food, and crush the waste food in a crushing cavity for many times mainly by means of a centrifugal force and then discharge the waste food into a sewer or reuse the waste food. By changing the form of waste food for timely harmless treatment, the waste food can be crushed into slurry liquid to be directly discharged through a sewer pipeline, which can easily achieve instant, convenient and fast kitchen cleaning, and avoid the breeding of germs, mosquitoes and peculiar smell of waste food due to storage, thereby effectively optimizing a home environment.

Cutters of an existing kitchen waste disposer have a too small effective grinding area, and the cutters are all vertical sections, which easily lead to splash after colliding with food waste. The cutters have a relatively single effect on kitchen waste. In an existing grinding structure, a grinding process of a moving cutter set and a fixed cutter set is put on the same level as a grinding process of a cutter. As a result, part of the kitchen waste goes through only one of the processes, resulting in reduced efficiency, so that part of waste food is filtered out without the grinding process. The arrangement of the cutter sets is relatively simple, so that fine grinding operations cannot be completed, and the treatment of kitchen waste is not fine enough, resulting in increased difficulty in discharge.

The classification of domestic waste has been gradually performed throughout China. According to the latest classification requirements for domestic waste, daily kitchen waste mainly includes household kitchen waste, food waste, other kitchen waste, and the like. This type of waste has a high moisture content and main components including protein, fat, carbohydrates, inorganic salts, and the like, and thus is also referred to as “wet waste” and “perishable waste”. If this type of waste is not well classified, the waste may pollute other recyclable waste and produce a strong peculiar smell. However, the existing kitchen waste disposer lacks a disassembly function, and although the existing kitchen waste disposer can purify waste gas, a filter layer cannot be replaced. As a result, the purification effect may be reduced in a long time, making it impossible to effectively purify the odor of the waste gas.

Therefore, it is necessary to provide a device for rapidly processing kitchen waste into an organic fertilizer to solve the above technical problems.

When the kitchen waste slides down along the fourth moving cutter, the first moving cutter and the second moving cutter have a greater shear force, which effectively solves the problem that the shear force is constant during cutting, which is not enough to cut waste blocks with higher hardness, resulting in frequent cutter jamming and damage of the moving cutters, so that manual intervention is reduced, and a smoother treatment process and better effect are achieved.

During treatment, the kitchen waste is heated and dried, and finally the kitchen waste is transformed into fine granular dry substances, which become an organic fertilizer for plants, and the like.
