Solid-liquid separation device for preparing biological organic fertilizer and solid-liquid separation method of solid-liquid separation device

Abstract

The invention discloses a solid-liquid separation device for preparing a biological organic fertilizer and a solid-liquid separation method of the solid-liquid separation device. The solid-liquid separation device comprises a bottom table, a plurality of supporting rods are symmetrically and fixedly connected to the bottom side of the bottom table; the bottom side of each supporting rod is fixedly connected with a buffering pad, and the upper side of the bottom table is symmetrically and fixedly connected with a plurality of fixing rods. The upper end of the fixed rod is fixedly connected with a separation box; a discharging opening is formed in one side of the separating box, the discharging opening is connected with a side door through a hinge, a pressing plate and a filtering plate are slidably connected into the separating box, and a plurality of filtering holes are formed in the filtering plate. The pressing plate moves up and down through the hydraulic telescopic rod, feeding and discharging are facilitated, when the hydraulic telescopic rod continuously applies pressure, the pressing plate begins to extrude raw materials on the upper layer of the filter plate, liquid in the materials is rapidly squeezed out under the action of pressure, and therefore the solid-liquid separation speed is greatly increased.

Description

technical field [0001] The invention relates to the technical field of bio-organic fertilizer preparation, in particular to a solid-liquid separation device for bio-organic fertilizer preparation and a solid-liquid separation method thereof. Background technique [0002] With the development of aquaculture enterprises, the country's requirements for environmental protection are becoming more and more stringent, and more efforts are being made to control the environment polluted by sewage and feces from farms. More and more sewage and feces from farms can be used as raw materials for the production of bio-organic fertilizers; [0003] In the preparation process of bio-organic fertilizer, solid-liquid separation is an important step. For example, when using animal feces as raw materials for the processing of bio-organic fertilizers, in the process of large-scale animal husbandry, due to the washing of breeding facilities or breeding grounds or the leakage of water equipment fo...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to solve the problem in the prior art that "the separated solid still has a small amount of water, and the separation efficiency is low; after the solid-liquid separation, workers need to collect and transport the liquid and solid respectively, which affects the bio-organic fertilizer. The shortcoming of the overall preparation efficiency of ", and proposed a kind of solid-liquid separation device and its solid-liquid separation method for bio-organic fertilizer preparation
