Problems solved by technology

[0002] Since the 21st century, the rapid development of my country's industrial sector has produced a large amount of industrial waste (such as steel slag, fly ash, coal gangue, ceramic waste, and construction waste). If these industrial wastes are used unreasonably, they will not only cause serious pollution to the environment, and waste resources
There are many raw materials for permeable bricks currently used, such as: coal gangue, slag, steel slag, clay, fly ash, etc., and the permeable bricks currently on the market not only have uniform pore distribution, but for road surface water, only It plays the function of water seepage, but cannot play the function of water filtration; and because coal gangue, slag, steel slag, clay, fly ash and other raw materials can also be recycled in other industries, they are used as raw materials
The cost is relatively high
At present, a large amount of ceramic solid waste is still in a state of undeveloped recycling. If this large amount of ceramic solid waste cannot be recycled, it will cause serious pollution to the environment.

Embodiment 1

[0028] A method for manufacturing gradient hole permeable bricks from ceramic solid waste, comprising the steps of:

[0029] 1. Weigh each component according to the following mass percentages: 80% ceramic solid waste, 8% kaolin, and 12% feldspar;

[0030] 2. Perform external force crushing, ball milling, and sieving of the weighed ceramic solid waste to obtain waste particles and powders with different particle sizes and meshes, and divide the particle size meshes into 10-14 meshes into one level (including 12 meshes) 16-24 mesh is divided into two grades (including 20 mesh), 30-70 mesh is divided into three grades (including 50 mesh), 100-200 mesh (including 150 mesh) is divided into four grades of powder,

[0031] 3, in step 2 gained different mesh size ranges are divided into all levels of powder and grain, add kaolin, feldspar in proportion by the actual weight of each level of powder and grain;

[0032] 4. Add the materials of all levels obtained in step 3 into the mold...

Embodiment 2

[0035] Embodiment 2, embodiment 2 is on the basis of embodiment 1, in order to further improve the various technical indicators of permeable bricks, the technical measures taken, the specific manufacturing method steps are:

[0036] 1. Weigh each component according to the following mass percentage: ceramic solid waste 75%, kaolin 3%, water glass 2%, feldspar 17%, sugar filter mud 3%,

[0037] 2. Perform external force crushing, ball milling, and sieving of the weighed ceramic solid waste to obtain waste particles and powders with different particle sizes and meshes, and divide the particle size meshes into 10-14 meshes into one level (including 12 meshes) 16-24 mesh is divided into two grades (including 20 mesh), 30-70 mesh is divided into three grades (including 50 mesh), 100-200 mesh (including 150 mesh) is divided into four grades of powder,

[0038] 3, in step 2 gained all levels of powder granules, add kaolin, water glass, dolomite and sugar filter mud in proportion by the...

Embodiment 3

[0043] 1. Weigh each component according to the following mass percentage: 80% ceramic solid waste, 5% kaolin, 5% feldspar, 5% dolomite, 3% sugar mud and 2% calcium carbonate;

[0044] 2. Perform external force crushing, ball milling, and sieving of the weighed ceramic solid waste to obtain waste particles and powders with different particle sizes and meshes, and divide the particle size meshes into 10-14 meshes into one level (including 12 meshes) 16-24 mesh is divided into two grades (including 20 mesh), 30-70 mesh is divided into three grades (including 50 mesh), 100-200 mesh (including 150 mesh) is divided into four grades of powder,

[0045] 3, in step 2 gained all levels of granules, add kaolin, feldspar, dolomite and calcium carbonate in proportion by the actual weight of granules of all levels;

[0046] 4. Put the materials of all levels obtained in step 3 into the mold in turn, and apply pre-pressure to push the indenter into the mold to flatten it, and then spray a l...

Abstract

The invention discloses a method for manufacturing water-permeable bricks with gradient holes from ceramic solid waste materials. The method includes steps that the ceramic solid waste materials are used as main raw materials for the water-permeable bricks, ball-milling variables are controlled, then grading is carried out according to the weights of screen residues and the particle size distribution of powder after ball-milling is carried out, a few adhesion agent and sintering aid mixed materials are added into different grades of raw materials at different particle size grades, the variousgrades of raw materials with the maximum mesh numbers are discharged into molds at first, then the materials at the secondary mesh number grades are discharged, and so on, pressures are ultimately applied to prepare green bricks by means of one-step forming, and the green bricks are fired by means of drying and firing at the temperatures of 900-1300 Celsius degrees for the firing time of 1-10 hours to form the water-permeable bricks with gradient hole structures. The method has the advantages that equipment is simple, the porosity and gradient structures can be controlled, the water-permeablebricks can simultaneously have water seepage and water filtration functions, the method is high in industrial waste material treatment capacity and has a high economic benefit, and the like.

Description

technical field [0001] The invention belongs to a method for manufacturing water-permeable materials, and relates to a method for manufacturing gradient hole water-permeable bricks by using ceramic solid waste. Background technique [0002] Since the 21st century, the rapid development of my country's industrial sector has produced a large amount of industrial waste (such as steel slag, fly ash, coal gangue, ceramic waste, and construction waste). If these industrial wastes are used unreasonably, they will not only cause serious pollution to the environment, And it wastes resources. However, most of the research on inorganic solid waste in our country is currently concentrated on fly ash and coal gangue, and there is very little research on the utilization of ceramic waste. [0003] Ceramic solid waste (waste) belongs to the scope of solid inorganic waste, which mainly includes damaged ceramic products, industrial ceramic fillers, ceramsite, floor and wall tiles, ceramic fil...
