Cow dung extrusion dehydration device

Abstract

The invention discloses a cow dung extrusion dehydration device, which relates to the technical field of cow dung dehydration devices, which facilitates the addition of cow dung and the discharge of cow dung after extrusion, forming a continuous operation without manual removal of cow dung from extrusion In addition, reduce the labor intensity. The present invention comprises a shell, a pressure bearing plate is arranged inside the housing, several drainage holes are opened through the pressure bearing plate, a filter cloth is arranged on the upper end of the pressure bearing plate; The end is connected with the inner wall of the shell in rotation, the lower end of the pressure bearing plate can be detachably provided with support components located on both sides of the roller shaft, the upper part of the pressure bearing plate is provided with a pressure applying plate, and the upper end of the pressure applying plate is provided with a feeding cylinder. The top of the pressure plate is provided with a positioning protrusion which is compatible with the inner wall of the feeding cylinder, and the lower part of the pressure plate is provided with a vibration unloading device.

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 cow dung. However, due to the accumulation of cow dung, the cow dung afte...

[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 cow dung. However, due to the accumulation of cow dung, the cow dung after extrusion There is a large amount of residual water in the cow dung, and the water extruded from the upper layer of cow dung penetrates downward, and a part of the water often remains on the surface of the lower cow dung during the infiltration process; after the cow dung is squeezed, it needs to be manually cleaned The dung is removed and cleaned, and 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 slag is mixed with water to form a solid-liquid mixture , if the solid-liquid mixture is discharged directly, it will cause waste of resources and affect the environment
