A device for composting kitchen waste

Abstract

The invention discloses a device for composting kitchen waste, which comprises: a first box body, a connecting section and a second box body arranged in sequence from left to right in the horizontal direction, and the outer wall of the first box body is fixed around the There are solar panels, and a constant temperature heating rod hangs downward from the center of the top in the first box. A battery is placed on the side of the bottom of the first box away from the second box, and an inclined plate is set to connect the battery with the rest of the first box. The internal space is isolated; in the second box, a vertical cylinder is suspended in the middle, the bottom of the cylinder is a mesh plate, and a cylindrical carbon mesh is set inside the cylinder, and a fan is arranged inside the carbon mesh. The side of the bottom of the second box away from the first box is constructed with an inclined sieve plate and the side wall of the second box to form a space, which is filled with anthracene-based metal-organic framework material, and an ultraviolet lamp and a xenon lamp are also arranged in the center; The connecting section is provided with a horizontal screw propeller. The device of the invention can process kitchen waste with zero power consumption and high efficiency and obtain compost.

Description

technical field [0001] The invention belongs to the field of fertilizer manufacture, and in particular relates to equipment for fertilizer manufacture made from household or municipal garbage. Background technique [0002] In domestic waste, kitchen waste accounts for up to 50% to 70%, and kitchen waste is the main pollution source of urban domestic waste. The source separation of kitchen waste can not only avoid the mutual pollution between the various components of the waste, but also greatly reduce the pressure of terminal treatment. Kitchen waste is rich in organic matter, oil, and nutrients (nitrogen, phosphorus, potassium, calcium, and various trace elements), and has high utilization value. The treatment method is mainly resource-oriented. Looking at the kitchen waste treatment models of various countries, most of the United States composts kitchen waste and yard waste on a household basis; Japan promotes the reduction of the total amount of food waste, recycling as ...

AI Technical Summary

Problems solved by technology

However, there are still a series of problems in the anaerobic treatment of kitchen waste: there is no mature professional technology and equipment, and there is a gap compared with foreign countries, and the technical equipment has not met the requirements of commercialization and industrialization; moreover, during the composting process, Excessive moisture content will affect the heating process of the compost, which will directly affect the composting cycle. At the same time, the high moisture content will also reduce the volume load of the device and reduce the efficiency of the device.
