AI Technical Summary

Technical Problem

Existing sludge drying hoppers have low drying efficiency and are prone to clogging when processing materials with smaller particle sizes, especially the air guide column and side air outlet area, which are easily blocked by the dried material.

Method used

An exhaust plate and an inverted U-shaped exhaust plate are installed in the hopper. The side wall of the exhaust plate is equipped with an air outlet and an extension cover. An extension cover is installed above the air outlet to prevent material from entering, increase the conveying position of flowing air and prevent blockage.

Benefits of technology

It improves material drying efficiency, avoids clogging, and ensures that flowing air can continuously deliver material to multiple locations, thus improving the drying effect.

Abstract

本实用新型公开了一种增强型污料干化料斗，料斗本体包括围板和底板，围板与底板之间形成干化腔，底板上设有多个与干化腔相连通的进气孔，侧排风结构设置于围板的内侧壁上，侧排风结构包括多个排风板，排风板呈倒U形结构，并具有与干化腔的底部相连通的进气腔，排风板的侧壁上设有多个与进气腔相连通的出气口，且位于出气口的上方设有延伸罩，延伸罩向下弯折并与出气口之间形成间隙，且出气口的水平投影位于延伸罩的水平投影内。本实用新型通过设置排气板可以增加物料内部输送流动空气的位置，并在排气板的出气口上侧设置延伸罩可以避免物料通过出气口进入进气腔内，保证排风板输送流动空气的效果，提高物料的干化效率。
