Bio-organic fertilizer double-roller extrusion granulator

Abstract

The invention belongs to the field of organic fertilizer manufacturing equipment, and more specifically relates to a bio-organic fertilizer double-roller extrusion granulator. The bio-organic fertilizer double-roller extrusion granulator comprises a rack, a pair of extrusion rollers and a demolding mechanism; the extrusion rollers are mounted on the rack, and hemispherical grooves are formed on the outer circular surfaces of the extrusion rollers; the demoulding mechanism comprises ejection pillars, traction magnets and reset mechanisms; each extrusion roller is provided with a sliding tract communicated with the corresponding semispherical groove, and the sliding track is arranged along the radial direction of the extrusion roller; the ejection pillars are arranged in sliding fit with thesliding tracks; the traction magnets are installed on the rack and below the extrusion rollers; the acting force of the reset mechanisms on the ejection pillars is designed to face the axis of the extrusion rollers. According to the invention, the traction magnets are arranged below the extrusion rollers, so that the ejection pillars rotating to be below the extrusion rollers are driven to stretch out for ejection out of organic fertilizer particles in the semispherical groove, and the ejection pillars rotate to be above the extrusion rollers are driven to retract into the sliding tracks under the action of the reset mechanisms, so that entering of organic fertilizer raw materials into the semispherical grooves is not influenced, and the quality of the organic fertilizer particles can beensured.

Description

technical field [0001] The invention relates to the field of organic fertilizer manufacturing equipment, in particular to a bio-organic fertilizer double-roll extrusion granulator. Background technique [0002] Organic solid waste usually refers to animal and plant waste such as animal manure or plant residues. Organic fertilizer manufacturers usually use organic solid waste as raw materials to make organic fertilizers. The production process of organic fertilizer mainly includes mixing, crushing, granulating, drying, cooling, screening and packaging. Among them, granulating organic fertilizers can not only make the appearance of organic fertilizers beautiful and facilitate preservation, but also play a role in slow release and prolong the fertilizer effect time of organic fertilizers. The roller extrusion granulator is a commonly used granulation method for organic fertilizers. equipment. The double-roll extrusion granulator includes a pair of extrusion rollers, which are...

AI Technical Summary

Problems solved by technology

This twin-shaft pair-roller extrusion granulator has the following disadvantages: (1) the air blown by the blower blows out through the air hole, which will hinder the raw material from entering the groove, resulting in a decrease in the density of the organic fertilizer particles, which not only affects the quality of the organic fertilizer, but also The decrease in density makes it harder for the particles to leave the hemispherical groove; (2) The powdery organic fertilizer raw material will be squeezed into the pores, which not only affects the shape of the organic fertilizer particles, but also makes it more difficult for the organic fertilizer particles to leave the hemispherical groove
