Cow dung extrusion dehydration device

Abstract

The invention discloses a cow dung extrusion dehydration device, and relates to the technical field of cow dung dehydration devices. Cow dung is convenient to add and is discharged after being extruded, continuous operation is formed, the cow dung does not need to be removed from the extrusion position, and thus the manual labor intensity is reduced. The cow dung extrusion dehydration device comprises a shell, a pressure-bearing plate is arranged inside the shell, a plurality of drainage holes are formed in the pressure-bearing plate in a penetrating mode, and a filter cloth is arranged at theupper end of the pressure-bearing plate; and a roller shaft is arranged in the middle of the lower end of the pressure-bearing plate, the two ends of the roller shaft are rotationally connected withthe inner wall of the shell, supporting assemblies located on the two sides of the roller shaft correspondingly are further detachably arranged at the lower end of the pressure-bearing plate, a pressure-applying plate is arranged above the pressure-bearing plate, a feeding cylinder is arranged at the upper end of the pressure-applying plate, a positioning bulge mutually matched with the inner wallof the feeding cylinder is arranged at the upper end of the pressure-bearing plate, and a vibrating discharging device is obliquely arranged below the pressure-bearing plate.

Description

technical field [0001] The invention relates to the technical field of cow dung dehydration devices, in particular to a cow dung extrusion dehydration device. Background technique [0002] Dry cow dung contains 10%-20% of crude protein, 1%-3% of crude fat, 20%-30% of nitrogen-free extract, 15%-30% of crude fiber, so it has high nutrients. Cow dung can loosen the soil, improve soil compaction, chelate trace elements in the land, improve soil fertility, etc., so a lot of cow dung is used as fertilizer, but because cow dung contains a certain amount of water when collected, it is not easy to store and transport, so generally All need to be dehydrated and then made into fertilizer for fertilization. [0003] However, the existing dry cow dung extrusion device is inconvenient to feed. A large amount of cow dung is often added at one time, and then the cow dung is squeezed to squeeze out the moisture in the dung. However, due to the accumulation of dung, the moisture in the dung ...

[0002] Dry cow dung contains 10%-20% of crude protein, 1%-3% of crude fat, 20%-30% of nitrogen-free extract, 15%-30% of crude fiber, so it has high nutrients. Cow dung can loosen the soil, improve soil compaction, chelate trace elements in the land, improve soil fertility, etc., so a lot of cow dung is used as fertilizer, but because cow dung contains a certain amount of water when collected, it is not easy to store and transport, so generally All need to be dehydrated and then made into fertilizer for fertilization

[0003] However, the existing dry cow dung extrusion device is inconvenient to feed. A large amount of cow dung is often added at one time, and then the cow dung is squeezed to squeeze out the moisture in the dung. However, due to the accumulation of dung, the moisture in the dung after extrusion The residual amount is large, and the water extruded from the upper layer of feces penetrates downward. During the infiltration process, a part of the water often remains on the surface of the lower layer of feces; after the extrusion of cow manure, it is necessary to manually remove and clean the cow manure The next cow dung extrusion dehydration can only be carried out after the cow dung has been cleaned. The work efficiency is low and the labor intensity of the workers is high; during the extrusion process, part of the cow dung residue is mixed with water to form a solid-liquid mixture. The liquid mixture is discharged, causing a waste of resources and affecting the environment
