Crayfish shell recycling, drying and dehydrating device

Abstract

The invention discloses a crayfish shell recycling, drying and dehydrating device. The crayfish shell recycling, drying and dehydrating device comprises a box body; a feeding hopper is fixed to the left side of the outer wall of the top of the box body; furthermore, a material guiding pipe is fixedly inserted between the feeding hopper and the box body; a rotating wheel is rotationally installed in the material guiding pipe; multiple hinge shafts distributed at equal intervals are fixedly hinged to the circumferential outer wall of the rotating wheel; crushing plates are rotatably mounted on the hinge shafts; springs are fixed between the crushing plates and the circumferential outer wall of the rotating wheel; triangular protruding blocks with the same number as the crushing plates are fixed to the circumferential outer wall of the rotating wheel; first triangular teeth distributed at equal intervals are fixed to the outer walls, close to the inner side faces of the crushing plates, of the triangular protruding blocks; second triangular teeth distributed at equal intervals are fixed to the inner side face of the crushing plate; and a grinding table matched with the rotating wheelis fixed to the inner wall of the left side of the material guiding pipe. The crayfish shell recycling, drying and dehydrating device disclosed by the invention can effectively crush and dry crayfishshells and improve the drying efficiency.

Description

technical field [0001] The invention relates to the technical field of recycling and drying equipment for shrimp shells, in particular to a drying and dehydrating device for recycling shrimp shells of crayfish. Background technique [0002] Crayfish are native to northern Mexico and the southern United States. Its whole body is dark red, the carapace part is nearly black, there is a wedge-shaped stripe on the back of the abdomen, and the pincers are narrow and long. The middle part of the carapace is not separated by mesh-like gaps, there are obvious grains on the carapace, and the frontal sword has lateral spines or the frontal sword end has notches. Fast growing and adaptable, it inhabits permanent streams and swamps. [0003] A large number of discarded shrimp shells are produced every year due to the consumption of shrimp in the world. The discarded shrimp shells are rich in nitrogenous substances such as chitin, protein, and CaCO3. The total amount of these discarded...

AI Technical Summary

Problems solved by technology

In my country, only a small number of discarded shrimp shells are made into animal feed, and the vast majority of shrimp shells are treated as a waste of agricultural and sideline products. In the process of recycling shrimp shells, shrimp shells need to be dried. There are some shortcomings in the use of drying equipment. For example, if the head and gills of crayfish are not crushed, the drying will not be sufficient and cannot meet the drying needs.
