Abstract
The invention discloses a kind of hollow brick manufacture crafts, and gangue and cinder crushing are first filtered out the coal gangue particle that partial size is 2-3mm and the coal slag granules that partial size is 3-5mm respectively；Gangue and clay are aged 3-5 days again, then coal slag granules are individually aged 1-3 days；Mixture and cinder are stirred to get into pug according to the proportion of 1:0.1-1:0.2 again, pug is added to extrusion molding in extruder, by molding hollow brick naturally dry 2-3 days；The temperature of dry kiln is first raised at 140-150 DEG C dry 4-6h；The temperature of dry kiln is raised at 170-180 DEG C dry 2-4h again；The temperature of dry kiln is raised at 230-240 DEG C dry 2-3h again；Hollow brick after drying is fired in firing kiln and obtains finished product hollow brick.The present invention is improved by the manufacture craft to hollow brick, realizes increasing substantially for hollow brick intensity.
Description
Technical field
The present invention relates to a kind of hollow brick manufacture crafts.
Background technique
Since the raw material of hollow brick light weight, consumption is few, compared with existing solid brick, can largely save soil soil and
It bakes bricks fuel, mitigates shipping mass；Labor intensity when mitigating brickmaking and laying bricks, accelerates construction progress, and mitigates oneself of building
Weight, reduces the cost in house, and therefore, hollow brick gradually becomes instead of solid brick commonly to be built in building trade in recent years
Build material；But by the defect of hollow brick also gradually being found, in order to enable hollow brick is energy saving for a long time to the use of hollow brick
Building materials, the advantage of light quality are more prominent, so that the compression strength of hollow brick is greatly cut down, result in using hollow brick in this way
The requirement of Construction intensity is not achieved in the wall of renovation, therefore, behind just occurred that 4-6 grade of earthquake occurs, hollow brick renovation
There is the case where large area is collapsed in house, and not only causes serious damage to the property of people, even results in people and has lost treasure
Expensive life.
Therefore, now in order to enable hollow brick is not replaced gradually on the market, how most of producers all change in research
Into the strength problem of hollow brick, everybody is to realize mentioning for hollow brick intensity how research improves the ingredient of hollow brick now
Rise, but current research achievement be or the intensity of hollow brick change less or be exactly in order to reach the intensity of target,
So that the cost of material of hollow brick is higher by 1 times or so than the manufacturing cost of original hollow brick.
Summary of the invention
For the above problem in the prior art, the invention proposes a kind of hollow brick manufacture crafts, solve present sky
The intensity difference of heart brick, the technical problems such as production cost height of improved hollow brick.
The technical solution of the present invention is as follows: a kind of hollow brick manufacture craft, includes the following steps:
1) gangue transported from coal yard is crushed, smashed gangue is ground by grinder, screening
Obtain the coal gangue particle of 2-3mm；The effect that grinding gangue is aged gangue and clay is more preferable, also makes below
The tightness of the molding hollow brick of compacting is more preferable.
2) cinder is crushed, screening obtains the coal slag granules of 3-5mm；
3) clay of 30%-50% is added in mass ratio and is stirred for grate coal spoil particle in step 1), stirs
Suitable water is added while mixing, so that the water content of mixture is 15%-17%；
4) mixture in step 3) is aged 3-5 days in ageing tank；Cinder in step 2) is individually aged
1-3 days；
5) by after ageing mixture and cinder be added in agitating device and stir according to the proportion of 1:0.1-1:0.2
It mixes, while suitable water being added into agitating device, so that the water content of the pug after stirring is 18%-20%；It is suitable
Cinder, which is added, makes the permeability of hollow brick more preferable, so that the drying of back hollow brick and firing effect are more preferable, sky can be improved
The intensity of heart brick.
6) pug in step 5) is added to the hollow brick of extrusion molding in extruder, then certainly to molding hollow brick
So dry 2-3 days；
7) molding hollow brick obtained in step 6) is transported in dry kiln again and carries out dynamic drying, first by dry kiln
Temperature is raised at 140-150 DEG C dry 4-6h；Then the temperature of dry kiln is raised at 170-180 DEG C dry 2-4h again；Finally
The temperature of dry kiln is raised at 230-240 DEG C dry 2-3h again；Last dry kiln carries out Temperature fall；Make it possible in this way by
The drying effect of molding hollow brick entirety is uniform, can guarantee that hollow brick can be fired uniformly in this way, avoid local firing
Effect is poor, influences the intensity of entire hollow brick.
8) hollow brick finished dry in step 7) to be fired in firing kiln, the temperature of firing kiln is 900-1000 DEG C,
Hollow brick finished product is finally obtained, the control firing time is 60-64h.
Further, the partial size for the coal gangue particle that screening obtains in the step 1) is 2.5mm.
Further, the partial size for the coal slag granules that screening obtains in the step 2) is 4mm；
Further, 40% clay is added in the step 3) in mass ratio in coal gangue particle.
Further, the temperature of dry kiln is raised at 145 DEG C dry 5h first in the step 7)；Then it will dry again
The temperature of kiln is raised at 175 DEG C dry 3h；The temperature of dry kiln is finally raised at 235 DEG C dry 2.5h again；Last dry kiln
Carry out Temperature fall.
Further, the firing temperature of hollow brick is 965 DEG C in the step 8), finally obtains hollow brick finished product, is controlled
Firing time is 62h.
Compared with prior art, the beneficial effects of the present invention are:
The present invention by by hollow brick on the basis of existing raw material forms the appropriate adjustment composition ratio of raw material, then
Basic improvement has been carried out from the burning process of hollow brick, and improves the crushing and screening process of raw material, the ageing work of raw material
The intensity of sequence, dynamic drying process etc., the hollow brick fired through the invention in this way can reach 41.3MPa, with existing MU30
The intensity of hollow brick is compared, and 10MPa or more is improved, so that the strength character of hollow brick is more preferable, but the life of hollow brick
Cost is produced to be basically unchanged.
