Automatic sorter of kitchen waste

Abstract

The invention relates to the technical field of environmental equipment, in particular to an automatic sorter of kitchen waste. The automatic sorter is characterized by comprising a screen trough, a screen cover plate, a separating shaft, separating blades, a filter net and a separating motor; the upper end of the screen trough is connected with the screen cover plate, and accordingly a separating cavity forms between the screen trough and the screen cover plate; the filter net and the separating shaft are disposed inside the screen trough; a kitchen waste outlet and a liquid outlet are formed between the filter net and the screen trough; one end of the screen trough is provided with a kitchen waste inlet, and the other end of the screen trough is provided with a separated material outlet; the bottom of the screen trough is provided with the kitchen waste outlet and the liquid outlet; the inner wall of the kitchen waste inlet of the screen trough is provided with a breaker plate; one end of the separating shaft passes the center of the breaker plate and is fixedly connected with the screen trough; the other end of the separating shaft passes the screen trough and is connected with the separating motor outside the screen trough through a transmission device; the separating blades are axial. The automatic sorter has the advantages such as simple structure, use convenience, high separating efficiency, separation thoroughness, operational stability and avoidance of manual sorting.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to an automatic sorting device for kitchen waste. Background technique [0002] As we all know, with the improvement of people's living standards, the degree of kitchen waste is astonishingly high. These kitchen wastes include rice, flour, food residues, vegetables, animal and vegetable oils, flesh and blood, plastic bags and chopsticks, etc., and sometimes There are hard substances such as forks, mineral water bottles, coke bottles, beverage bottles, and fast food boxes. In order to deal with these kitchen wastes, materials that cannot be decomposed, such as plastic bags, chopsticks, and hard substances, are usually separated by manual sorting. Separated from the kitchen waste, because the kitchen waste is easy to rot and deteriorate, it will produce an unacceptable pungent smell, which will cause unnecessary pollution to the body of the person who sorts ...

AI Technical Summary

Problems solved by technology

[0003] In response to the above problems, CN102580850A discloses a pre-sorting device for kitchen waste on the Internet. The sorting device is composed of an inner and outer double-layer screen cylinder composed of a material inlet, an inner cylinder, and an outer cylinder, a separation motor, a coarse material output port, and a fine material. It is composed of an output port, which is connected to the inner cylinder through the feeding port. At the feeding port, there are bag cutting teeth for cutting the garbage bags containing garbage. There is also a magnetic separation device for collecting metals at the feeding port. The cylinder and the outer cylinder are fixed together, and the separation motor drives the inner cylinder and the outer cylinder to rotate at the same time. The inner walls of the inner cylinder and the outer cylinder are respectively equipped with spiral blades, and the outer cylinder wall is also equipped with oil-water filtration channels. The wall is provided with a number of openings for filtering mineral water bottles, coke cans, beverage bottles, fast food boxes, disposable tableware, plastic bags and other coarse waste. The coarse waste is conveyed to the The coarse material output port, the fine material falls into the space between the inner cylinder and the outer cylinder through the opening, the oil and water are discharged through the oil-water or rate channel provided on the outer cylinder wall, and the remaining kitchen waste passes through the outer cylinder wall The provided spiral blade is transported to the discharge port, and the metal substances are absorbed by the magnetic separation device entering the feed port. The disadvantages are: the structure is unreasonable and not practical. First, there is a magnetic separation device at the feed port , because metal substances are covered by kitchen waste, the magnetic effect on metal is small, which is not conducive to adsorption. It can only absorb metal substances close to the magnetic separation device, and after adsorption, it is easy to absorb Second, in the process of sorting coarse and fine materials, substances such as chopsticks or forks are easy to get stuck in the cavity between the inner cylinder and the outer cylinder, which leads to blockage, which is not conducive to kitchen waste Classification and separation of objects
