Description

A sludge chelating brick making machine

Technical Field

The utility model relates to the technical field of sludge brick making equipment, in particular to a sludge chelating brick making machine.

Background Art

As we all know, with the accelerated urbanization process in my country, the treatment of landfill leachate has received more and more attention from all regions. The sludge after landfill leachate treatment contains pollutants such as heavy metals, which has become a difficulty in landfill leachate treatment. In order to truly carry out full-scale treatment and maximize resource utilization, sludge solidification resource brick making equipment has appeared on the market, which can make sludge into blocks for secondary use.

For example, a Chinese utility model patent discloses a high-efficiency sludge brick-making equipment (CN218195927U), which involves the field of sludge brick-making equipment, including a sludge brick-making machine, a brick-making mold is provided on the sludge brick-making machine, a support plate is fixedly installed on one side of the brick-making mold, a material frame is movably installed on the top side of the support plate, and a bottom plate is fixedly installed on one side of the sludge brick-making machine. Through the arrangement of linkage motor, sludge silo, linkage gear and other structures, the linkage motor can be started when the sludge material is loaded, and the sludge silo can be reciprocated under the action of the linkage motor. When the sludge silo moves, the unloading roller is driven to rotate under the action of the linkage gear, so that the material can be intermittently dropped out, and the reciprocating movement of the sludge silo can be coordinated to make the material evenly sprinkled into the material frame to prevent the material from piling up, thereby ensuring that the material can evenly enter the mold during brick making, and improving the effect of the finished brick.

However, when the inventors implemented this device, they found the following defects: in the process of making sludge bricks, it is often necessary to add appropriate amounts of additives and curing agents, and the additives and curing agents are often directly in contact with the sludge and then mixed by traditional stirring methods, but the mixing uniformity and mixing effect are poor, and the concentrated addition of additives and curing agents can easily cause local sludge particles to solidify, which has certain limitations in use.
