Stirring and uniform mixing device for preparation of sludge ceramsite

Abstract

The invention discloses a stirring and uniform mixing device for preparation of sludge ceramsite. The stirring and uniform mixing device comprises a mounting table. A stirring barrel is fixedly mounted on the mounting table. A stirrer driven by a motor a is arranged in the stirring barrel. A feeding hopper communicated with the stirring barrel is arranged at the top of the stirring barrel. A material conveying barrel mounted on a support is communicated with the bottom of the stirring barrel. A material conveying device driven by a motor b is arranged in the material conveying barrel. A discharging hopper communicated with the material conveying barrel is arranged at the bottom of the material conveying barrel. When the stirring and uniform mixing device is used, materials are added to thestirring barrel from the feeding hopper, the motor a drives a homogenizing shaft to rotate so as to drive a stirring shaft to rotate, a disc-shaped crushing knife is used for crushing the materials,meanwhile L-shaped homogenizing rods are used for stirring the materials, L-shaped stirring rods on the stirring shaft stir plugging materials again, then the materials enter the material conveying barrel, the motor b drives a material conveying shaft to rotate so as to drive a propeller to rotate, the materials are stirred and mixed while the materials are conveyed, the purpose of uniform mixingis achieved, the materials are discharged from the discharging hopper, and discharging is convenient.

Description

technical field [0001] The invention relates to a stirring and mixing device for preparing sludge ceramsite, belonging to the technical field of sludge treatment equipment. Background technique [0002] Ceramsite is a kind of lightweight aggregate, which has the advantages of low density, high strength, good heat preservation and heat insulation performance, etc. It is a new type of building basic material with excellent performance, and the market demand is very large. Traditional ceramsite is made of clay minerals. Due to the impact of clay mineral prices, the production cost is high, which limits the output of clay ceramsite and restricts the vigorous development of related industries. Using sludge as a raw material to prepare ceramsite not only can use the organic matter in the sludge as a gas product to make the ceramsite form a porous structure and reduce the consumption of other fuels, but also the inorganic components in the sludge can also be utilized. At the same ...

AI Technical Summary

Problems solved by technology

The existing method of making ceramsite from sludge is mainly to dry the wet sludge in a drier to become semi-dry sludge, and then mix the semi-dry sludge with other materials (clay and coal ash) evenly and then dry it in a granulator. The material balls are made in the middle, and then sent to the roasting kiln for roasting. The high-temperature ceramsite roasted in the roasting kiln enters the cooling cylinder for cooling and then sieves. The current mixing and mixing device has poor mixing effect and the discharge Inconvenient question
