AI Technical Summary

Technical Problem

Existing raw material crushing and impurity removal devices for sintered bricks are unable to effectively remove plant stems and aquatic weeds when processing river or lake bottom silt, resulting in the formation of pores or cavities during high-temperature sintering, which affects the strength and durability of silt sintered bricks.

Method used

Design a raw material pretreatment and impurity removal device for sintered brick production using silt, including a preliminary filtration and impurity removal device and a post-screening device. Utilize a filtration and screening roller and a metal impurity adsorption mechanism to screen and remove plant stems and aquatic weeds in advance, preventing them from entering the silt after crushing.

Benefits of technology

It improves the internal structural consistency and strength of sintered silt bricks, enhances product quality, avoids the formation of pores or cavities due to carbonization of impurities at high temperatures, and strengthens product durability.

Abstract

The purpose of this invention is to provide a raw material pretreatment and impurity removal device for the production of sludge sintered bricks. This device pre-screens plant stems or aquatic weeds before crushing, preventing them from entering the sludge sintered bricks after crushing. This improves the internal structural consistency and strength of the sludge sintered bricks, thus enhancing product quality. The device comprises a hollow outer shell. Within the internal cavity, from top to bottom, are arranged a preliminary filtration and impurity removal device, a guide plate, and a post-screening device. The preliminary filtration and impurity removal device includes a filtering and screening roller that rotates around a fixed central axis. The filtering and screening roller is hollow inside and open at one end. The outer wall of the filtering and screening roller is formed by a layer of filter screen material, which confines impurities from the sludge raw material entering the filtering and screening roller to its interior.
