Bone crusher

Abstract

The invention relates to a bone crusher. The bone crusher comprises a roasting mechanism, a crushing mechanism, a grinding mechanism, and a discharging mechanism; a roasting chamber is arranged in the roasting mechanism, and the roasting chamber is provided with a roasting inlet and a roasting outlet; the crushing mechanism comprises an outer cylinder and an inner roller; the outer cylinder and the inner roller are arranged to be coaxial, the inner roller is arranged in the outer cylinder, the inner roller and the outer cylinder rotate in opposite directions, the outer surface of the inner roller is provided with a first crushing tooth, the inner surface of the outer cylinder is provided with a second crushing tooth, a crushing channel is formed between the inner roller and the outer cylinder, and one end of the crushing channel is communicated with the roasting outlet; the grinding mechanism is connected with the other end of the crushing channel far away from the roasting outlet; the discharging mechanism is arranged on the bottom of the grinding mechanism, the discharging mechanism comprises a discharging channel, and one end of the discharging channel is connected with the grinding mechanism; the inner diameter of the outer cylinder reduces from the end close to the roasting outlet to the other end gradually. The bone crusher is used for crushing and grinding animal bone, and smashing bone into powder, so that nutrients in bone can be absorbed by plant easily, and offensive odor caused by decaying of bone in long time storing is avoided.

Description

technical field [0001] The invention relates to the technical field of waste food processing, in particular to a bone crusher. Background technique [0002] With the continuous development of my country's economy, the urban population is increasing day by day, the amount of garbage brought by the urban population growth is also increasing, and the urban environment is also deteriorating, which poses a huge threat to the health of citizens living in the city. How to quickly classify garbage and how to deal with it after classification are problems that need to be solved urgently. [0003] A large part of domestic waste is food residues, such as bones of various animals. These animal bones are difficult to handle because they are relatively hard. After a long time of storage, they will produce stench and affect the environment. But the bones of animals are actually rich in nutrients, which contain a lot of nutrients needed for plant growth. If the nutrients in the bones can b...
