Production system and production process for producing bricks by utilizing paper pulp sludge

Abstract

The invention belongs to the technical field of construction materials, in particular relates to a production system and a production process for producing bricks by utilizing paper pulp sludge, and aims to solve the technical problems of unreasonable design, complicated production process and the like in the prior art. The system sequentially comprises a brick making material conveying device used for conveying a brick making material, an agitation device used for agitating the brick making material, a molding device used for processing the brick making material into an adobe and a brick kiln used for firing the adobe into a brick finished product, as well as a paper pulp sludge adding mechanism used for adding paper pulp sludge into the brick making material, wherein the blanking end of the paper pulp sludge adding mechanism is positioned above the brick making material conveying device. The production process comprises the following steps: A, preparing raw materials; B, fermenting; C, molding an adobe; and D, firing a brick. The production system and the production process have the advantages of more reasonable design, simpler structure and simple process, and is easy to operate and produce.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a production system and a production process for producing bricks from pulp sludge. Background technique [0002] Environmental pollution is caused by unreasonable production or unadvanced technology, for example: In the paper industry, papermaking is a highly polluting and energy-intensive industry that produces waste, including waste water and sludge, etc. , Pulp sludge is produced by wood pulp manufacturing or recycled waste paper in the process of deinking, rinsing and pulping. It is flammable and generally dry and hard. At present, the sludge produced by papermaking is generally only It can be processed through centralized landfilling and incineration. These processing methods have at least the following defects: when using centralized landfilling, if the total amount of sludge is large, it needs to occupy a large amount of land resources. This not on...

[0002] Environmental pollution is caused by unreasonable production or unadvanced technology, for example: In the paper industry, papermaking is a highly polluting and energy-intensive industry that produces waste, including waste water and sludge, etc. , Pulp sludge is produced by wood pulp manufacturing or recycled waste paper in the process of deinking, rinsing and pulping. It is flammable and generally dry and hard. At present, the sludge produced by papermaking is generally only It can be processed through centralized landfilling and incineration. These processing methods have at least the following defects: when using centralized landfilling, if the total amount of sludge is large, it needs to occupy a large amount of land resources. This not only affects the surrounding environment, but also easily produces secondary pollution, especially the groundwater below the surface; when incineration is used, harmful gases will be generated during incineration, which will of course cause environmental pollution. In addition, the incineration cost is relatively high

[0004] The above-mentioned first scheme improves production efficiency and reduces labor production intensity to a certain extent, but this scheme also has at least the following defects: the structure of the entire manufacturing equipment is relatively complicated, and the production efficiency cannot meet the production requirements. In addition, through this The bricks produced by the scheme have low structural strength; the second scheme has achieved the purpose of turning waste into treasure and recycling resources to a certain extent, but this scheme fails to make full use of papermaking sludge, and there is a need for further optimization and improvement
