AI Technical Summary

Technical Problem

The existing pig slaughter waste treatment equipment has independent processing steps that lack coordination, resulting in a cumbersome process, low efficiency, high labor costs, and a high risk of secondary pollution.

Method used

The pretreatment unit, solid-liquid separation unit, main treatment unit, gas-solid purification unit, and graded resource utilization unit are integrated on the same main frame. The entire process is automated and linked through mechanical transmission and PLC control. Each unit is seamlessly connected, and the drive unit and control unit are integrated for synchronous operation and control.

Benefits of technology

It achieves closed-loop harmless treatment of pig slaughter waste throughout the entire process, reduces energy consumption and labor costs, avoids material leakage, sewage splashing and exhaust gas emission, and improves treatment efficiency and resource utilization.

Abstract

This invention discloses a harmless treatment device for waste from pig slaughtering, comprising a main frame and, sequentially mounted thereon, a pretreatment unit, a solid-liquid separation unit, a main treatment unit, a gas-solid purification unit, and a graded resource recovery unit. A drive unit synchronously drives each unit via mechanical transmission, and a control unit achieves fully automated control of the entire process. The pretreatment unit achieves stable feeding through adjustable arc-shaped clamps; the solid-liquid separation unit uses a vibrating grid for solid-liquid separation; the main treatment unit includes rolling rollers and a flexible peeling assembly to complete bone pyrolysis and meat separation; the gas-solid purification unit sprays and filters waste gas with activated carbon; and the graded resource recovery unit classifies and recovers bone residue, grease, organic residue, and circulating water. This invention features high integration and strong linkage, achieving a closed-loop, harmless, and resource-recovery treatment of slaughtering waste throughout the entire process, effectively preventing secondary pollution and improving treatment efficiency and resource recovery rate.
