Description
Technical field
The present invention relates to a kind of brick-making method of building brick.
Background technology
A large amount of projects of tearing down and building make that the demand of building brick is increasing, and present building brick nearly all is to adopt clay to fire to form, and need a large amount of diggings to plough, and cause a large amount of cultivated land resource losses and waste.The quantity discharged sharp increase of industrial waste such as flyash, coal gangue as not being used, will take a large amount of storage ash places, also contaminate environment.In order to reduce the clay consumption of brickmaking industry, accelerate the recycling of industrial wastes such as flyash, coal gangue, a lot of brickmaking enterprises begin to utilize flyash, coal gangue etc. to produce vitrified brick.Yet, traditional brickmaking technology coal consumption height, power consumption height, the calcium oxide content of some brick exceeds standard, and great quality accident takes place in quality instability easily, and overcast and rainy dry humidity discharging efficient is very low.
Summary of the invention
The object of the invention provides a kind of brick-making method, and this method coal consumption is low, power consumption is low, the steady quality of institute's product brick.
For achieving the above object, the technical solution used in the present invention is: a kind of brick-making method, and raw materials used is coal gangue, slag, shale, flyash and clay, produces according to the following steps:
(1) raw material is smashed worn into particle, granularity is below 2 ㎜;
(2) feed particles is mixed, add warm water and stir, make pug, carry out ageing then and handle, the time is more than 24 hours;
(3) adopt vacuum extruder that pug is made adobe, the main motor of vacuum extruder adds frequency transformer, and the vacuum tightness of vacuum extruder is ﹣ 0.07MPa～﹣ 0.08MPa, and moulding moisture is 13.5%～14.5%;
(4) adobe is placed into concentrated humidity discharging drying in the dry hole;
(5) utilize the residual carbon of feed coal spoil, slag and flyash, adopting internal combustion is that main, external combustion is that the method for assisting is carried out roasting;
(6) cool off finished product, detect the content of calcium oxide.
Coal gangue, slag, shale, flyash and clay constitutive material mixture, coal gangue, slag and shale are formed and are gathered materials, the calorific value of raw mix is 280～320kcal/kg, during the production standard brick, ratio 〉=20% gathers materials, the plasticity of raw mix is 7%～12%, the calcium oxide content of raw mix≤5%, when producing perforated brick, the ratio of gathering materials 〉=50%, the plasticity of raw mix is 9%～14%, the calcium oxide content of raw mix≤4.5%, when producing hollow brick, the ratio of gathering materials 〉=40%, the plasticity of raw mix is 11%～16%, the calcium oxide content of raw mix≤4%.
During the production standard brick, digestion time is more than 24 hours, and when producing perforated brick and hollow brick, digestion time is more than 72 hours.
During the production standard brick, the frequency of frequency transformer is 40～45Hz, and when producing perforated brick, the frequency of frequency transformer is 35～38Hz, and when producing hollow brick, the frequency of frequency transformer is 29～32Hz.
The adobe humidity discharging uses dry hole to concentrate moisture discharge device in the step (4), and the moisture discharging opening of described device is communicated with by the humidity discharging pipe, and humidity discharging pipe air outlet place is provided with induced exhaust, and induced exhaust is provided with vacuum fan, and the outlet of induced exhaust is communicated with the chimney stack sidepiece.
The present invention takes speed control by frequency variation because the main motor of vacuum extruder adds frequency transformer, adapting to the production of many kinds brick, thereby has reached the effect of economize on electricity, as following table:
| The production kind | Frequency converter frequency (Hz) | Power savings |
| Standard brick | 40～45 | 10～20% |
| Perforated brick | 35～38 | 24～30% |
| Hollow brick | 29～32 | 36～42% |
Detect calorific value, plasticity, calcium oxide content and the moisture content of each raw material earlier, make the Excel form, the ratio of adjusting each raw material makes the calorific value of raw mix, plasticity and calcium oxide content reach corresponding requirements.Coal gangue: calorific value 1200cal/kg, moisture 6%, plasticity 5%, calcium oxide 4%; Flyash: calorific value 800cal/kg, moisture 28%, plasticity 0%, calcium oxide 0%; Shale: calorific value 0cal/kg, moisture 8%, plasticity 18%, calcium oxide 5%; Clay: calorific value 0cal/kg, moisture 10%, plasticity 8%, calcium oxide 0%.
Made Excel form during with above raw material production perforated brick:
C4=B6*C6*(1-F6)+B7*C7*(1-F7)
D4=B6*D6*(1-F6)+B7*D7*(1-F7)+B8*D8*(1-F8)+B9*D9*(1-F9)
E4=B6*E6*(1-F6)+B7*E7*(1-F7)+B8*E8*(1-F8)+B9*E9*(1-F9)
F4=B6*F6+B7*F7+B8*F8+B9*F9
Thereby draw each raw material proportion, coal gangue 25%, flyash 5%, shale 30%, clay 40%.When the raw mix calorific value of coal gangue, slag, shale, flyash and clay composition is in 280～320kcal/kg, because coal gangue, slag and flyash itself have certain combustibility, in the roasting process, combustiblematerials in the brick body provides calorific value, thereby reduced outside coal consumption, coal consumption amount is ten thousand of 0～10kg/, thereby has reached the effect of economizing on coal.Because the content of calcium oxide in the raw mix has been controlled in strictness, has prevented exceeding standard of calcium oxide content, has guaranteed the quality of product.Adopt special dry hole, vacuum fan by extracting out in the moisture discharging opening, arrives the damp atmosphere in the dry hole in chimney stack by induced exhaust, is discharged in the middle of the atmosphere, has realized concentrated humidity discharging, has improved drying efficiency, when especially overcast and rainy, does not influence drying efficiency.
