Device for extracting and enriching micro-plastics in livestock and poultry excrement

Abstract

The invention discloses an extraction and enrichment device for micro-plastics in livestock and poultry excrement. The device comprises a device body, idler wheels, a cabinet door, an observation window, a feeding port, a first motor, a water pump, a water pipe, a second motor, a control panel, a shell, a water tank, supporting legs, an enrichment box, a bearing, a threaded rod, a third filter plate, rectangular grooves, a first filter plate, a threaded sleeve, a scraper, a second filter plate, a stirring box, an electric valve, fixed blocks, stirring blades, a rotating shaft and a spray head.The device has the beneficial effects that: the rectangular grooves are formed in one sides of the third filter plate, the second filter plate and the first filter plate, centralized collection of micro-plastics is facilitated, the four idler wheels are arranged, the device is convenient to move according to actual needs, filter holes of the third filter plate, the second filter plate and the first filter plate are sequentially increased, the micro-plastics with different diameters can be conveniently filtered and recycled, a small-aperture filter screen is adopted at the bottom of the enrichment box, the collected micro-plastics are convenient to enrich, and the working efficiency is improved.

Description

technical field [0001] The invention relates to an extraction and enrichment device, in particular to an extraction and enrichment device for microplastics in livestock and poultry feces, and belongs to the technical field of solid waste treatment. Background technique [0002] Compared with materials such as wood and metal, plastic products are low in cost and have advantages such as greater weight strength, lower thermal conductivity, durability and biological inertness. They are used in various fields, for example, from household products to personal Hygienic products, from the packaging industry to construction materials and so on. While enjoying the great convenience brought by plastic products, the problem of garbage pollution from a large number of plastic products also plagues people. A large number of plastic products are gradually decomposed into small particles of plastic through photodegradation, biological erosion, physical degradation, etc. This kind of plasti...

AI Technical Summary

Problems solved by technology

A large number of plastic products are gradually decomposed into small particles of plastic through photodegradation, biological erosion, physical degradation, etc. This kind of plastic material fibers, particles and fragments with a size of less than 5mm are defined as microplastics. When raising poultry and livestock , These poultry and livestock will inevitably ingest a certain amount of microplastics, which cannot be digested and will be excreted with feces, causing secondary pollution to the environment. Therefore, it is necessary to extract and enrich the microorganisms in poultry and livestock feces

[0003] The structure of the existing extraction and enrichment device is relatively simple. First, the existing device lacks a mechanism for soaking and mixing feces, so that the subsequent extraction is not thorough. Second, the existing device is not easy to move and is troublesome to use. Third, the existing device does not filter the microplastics in the feces thoroughly, causing many unnecessary losses
