Abstract
Disclosed are a hollow brick sintered by coal ash and boiler waste residue and a producing method. Clay is adopted as a raw material of hollow bricks generally at present, the clay contains few sand grains, is large in stickiness and plasticity, poor in air permeability and formed through wet plastic extrusion, and semi-finished products are prone to cracks; and coal adding is mainly depended on in a sintering process, energy consumption is large, and the environmental protection requirement cannot be satisfied. The hollow brick comprises 0.32-0.51 part of the coal ash, 1.2-1.9 parts of boiler waste residues and 2.47-3.93 parts of clay. The hollow brick is used as a building material.
Description
Technical field:
the present invention relates to a kind of flyash, boiler emission useless quarrel agglomerating hollow brick and making method.
Background technology:
The starting material of
hollow brick production now adopt clay as starting material mostly, and clay contains that sand grains is few, viscosity is big, plasticity is big, it is poor to see through gas property, mould extrusion molding through wet, and work in-process are prone to chap; The main external putting-in coal that leans in the sintering procedure, it is very big to waste energy, and can't reach environmental protection requirement.
The drying process of
hollow brick production at present remains traditional seasoning method, and drying cycle is long, influenced greatly by Changes in weather, is a very big constraint for quality product.
natural production hollow brick process is because main raw material is flyash, clay, and the chemical ingredients difference of flyash is very big, is not easy to be grasped by the people; Constraint to the hollow brick production process is very big; The difference of quality product is also very big, and clay is because classification is more numerous and diverse, and different clays has different chemical ingredientss; Be difficult to grasp its performance for the brickmaking industry, it can serious restriction quality product.
Summary of the invention:
the purpose of this invention is to provide a kind of flyash, boiler emission useless quarrel agglomerating hollow brick prescription and making method; Adopt the hollow brick mechanical property of the present invention's production good, be convenient to construction; Reduce the usage quantity of external putting-in coal in the production process, reached the effect of energy-saving and emission-reduction.
Above-mentioned purpose realizes through following technical scheme:
The useless quarrel of
a kind of flyash, boiler emission agglomerating hollow brick is become by the following raw materials in parts by weight array: 0.32 ~ 0.51 part flyash, 1.2 ~ 1.9 boiler emission is useless to be cut, 2.47 ~ 3.93 parts clay.
The making method of above-mentioned flyash, the useless quarrel of boiler emission agglomerating hollow brick, this method comprises the steps:
(1) the useless quarrel of described boiler emission is pulverized the diameter≤3mm of the useless quarrel of the boiler emission after the pulverizing;
(2) be that 0.32 ~ 0.51 described flyash, parts by weight are that the useless quarrel of boiler emission and the parts by weight of 1.2 ~ 1.9 pulverizing are that 2.1 ~ 2.5 water is mixed with parts by weight;
(3) just parts by weight to be that the mixture of 2.47 ~ 3.93 described clay, step (2) gained is incremental put into that stirrer is soft to stir, the stirring revolution is 38r/min;
(4) mixture that step (3) is stirred carries out secondary stirring, incrementally puts into that stirrer is soft to stir, and stirs 38r/ min;
(5) material that step (4) is obtained gets into the material storehouse through the soft stirring extruding of vacuum, therefrom extracts the air that contains in the material and excessive moisture content out, and vacuum is extruded work in-process mud bar, and extrusion pressure does1.2
~2
Mpa;
(6) described work in-process mud bar is transported to through mud bar machine cuts wall telephone set, cut into the water planting of required model;
(7) get into drying zone, through 7 ~ 8 days natural dryings, smash frame, go here and there the upper strata to lower floor, promote the inner face string drying to make water planting airing Cheng Ganpei to the outside through artificial;
(8) the kiln roasting is put in described dried training, kiln temperature is 800 ℃, and roasting time is 2 hours;
(9) inspection after construction.
Beneficial effect:
are 1. in the production process of hollow brick; The useless quarrel of boiler emission through mixing a certain proportion of flyash, pulverizing has changed the performance of original technology medium clay soil as tackiness agent, problem such as solved that air permeability is poor, viscosity big, bad plasticity, work in-process are difficult for dehydration, drying cycle is long.[0009] 2. reduces the use of external putting-in coal in the sintering procedure of hollow brick, practiced thrift the energy greatly, played the effect of environmental protection.
through this technology and elite ratio of weight and number, the hollow brick mechanical property of production is good, intensity is high, be convenient to construction, has sound insulation, heat insulation, not hollowing, the characteristics that do not chap, do not sink.
