Dual crushing device for bio-based organic fertilizer processing

Abstract

The invention relates to the technical field of organic fertilizer processing, and discloses a dual crushing device for bio-based organic fertilizer processing, and aims to solve the problem that when organic fertilizer materials are screened and crushed at present, soot blowing on a screen is not uniform, and consequently the screen is partially blocked. The dual crushing device for bio-based organic fertilizer processing comprises a box body, and a feeding hopper is installed on the outer wall of the box body; and a screening part is mounted on the inner wall of the box body. According to the dual crushing device, air is blown to screening holes of the screening part through an air outlet pipe, and therefore the screening part is prevented from being blocked; when the air outlet pipe rotates along with a rotating part, the end, close to the screening part, of the air outlet pipe inclines towards the inner wall of the box body under the action of centrifugal force, and effective inclination of the air outlet pipe is guaranteed through the weight of a balance weight part; along with rotation of the rotating part, a fixing piece jacks the balance weight part in a reciprocating manner, and therefore the air outlet pipe is pushed to incline away from the box body and reciprocates; and the processes are repeatedly executed, the air outlet pipe is in a reciprocating swing state, it is guaranteed that air is comprehensively blown to the screen holes of the screening part, and therefore the screening efficiency of the screening part is improved.

Description

Technical field [0001] The present invention relates to the field of organic fertilizer processing techniques, and more particularly to a dual crushing device for biological organic fertilizer processing. Background technique [0002] Organic fertilizers are mainly biomass, animal and plant waste, plant-residue processing, contain a variety of organic acids, peptides, and rich nutrient elements, can provide comprehensive nutrients for crops, one of common fertilizers. [0003] During the process of biological organic fertilizer, the material is needed to be pulverized, and the existing bio-organic fertilizer processing crushing device is generally provided with a screen for sieving materials, in order to avoid blockage of the screen. The screen is blown up, and the material in the screen is blown up, but there is currently a problem in blowing when the screen is blown, resulting in a decrease in sieving and crushing efficiency. Inventive content [0004] It is an object of the p...

Problems solved by technology

[0003] During the processing of bio-based organic fertilizers, the materials need to be pulverized first. The existing crushing devices for processing bio-based organic fertilizers are generally equipped with screens for screening materials. In order to avoid blockage of the screens , the screen will be blown to remove the material in the screen hole in time, but at present, there is a problem of incomplete blowing when blowing the screen, which leads to the reduction of screening and crushing efficiency
