Device and method for preparing selenium-rich organic fertilizer from traditional Chinese medicine residues

Abstract

The invention discloses a device and method for preparing a selenium-rich organic fertilizer from traditional Chinese medicine residues. The device comprises a feeding hopper, the feeding hopper is a rectangular hopper, and the outlet end of the lower portion of the feeding hopper is connected to a fermentation cavity through a filter plate in a penetrating mode; a pair of stirring paddles are symmetrically arranged in the fermentation cavity, the tail ends of the stirring paddles are connected with a stirring driving device outside the fermentation cavity, and the stirring driving device enables the stirring paddles to rotate in opposite directions; and a vertically-arranged partition plate is fixed to the center of the interior of the feeding hopper and divides the interior of the feeding hopper into two symmetrical side spaces, an extrusion plate is arranged in each side space, and the extrusion plates are rotationally connected with the upper end of the feeding hopper. Compared with the prior art, the extrusion plates perform intermittent extrusion action, so that materials with different hardness and toughness can be crushed, gaps between central filter rods are synchronously and intermittently changed under the connection action of adjusting connecting rods, so that materials can be effectively prevented from being blocked in the gaps between the filter rods.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a device and a method for preparing selenium-enriched organic fertilizer by using traditional Chinese medicine residue. Background technique [0002] With the development of the traditional Chinese medicine pharmaceutical industry, the discharge of the main solid waste of the pharmaceutical factory, the dregs, is also increasing day by day. The existing pharmaceutical companies mainly landfill or incinerate the dregs, which brings pollution to the environment and wastes resources. . Most traditional Chinese medicines are composed of plant roots, stems, leaves, flowers, fruits, seeds, and limbs, organs, and shells of poultry, animals, insects, and fish, as well as some minerals. Chinese medicine residues are rich in organic and inorganic minerals. Substances (including nutrients such as nitrogen, phosphorus, and potassium needed for plant growth), but also include ...

AI Technical Summary

Problems solved by technology

In the prior art, there is a way to use the medicinal residues by drying and chopping the medicinal residues and then mixing them with other materials for fermentation. However, due to the complex composition of traditional Chinese medicine materials, there are hard and flexible materials, it is difficult to uniformly chop them, and they have to be dried. It is convenient to process after drying and sorting, and it needs to be collected and then fermented. The processing process is long and the processing efficiency is reduced.
