Description
Technical field
The present invention relates to a kind of methods with cow dung dry method baking ceramsite, belong to haydite manufacture technology field.
Background technology
Haydite density is small, portion's hole is more, form and ingredient are uniform, and intensity is high, wear-resistant, and with good anticorrosive
Property, freeze-proof, shock resistance and insulating（Heat preservation, heat-insulated, sound insulation, moisture resistance）, so be widely used in building materials, agricultural,
Industry, gardening, fire-resistant heat insulating material, environmental project and other field.Currently, there are many method of production haydite, the use such as Zhu Xiang
Sludge, cow dung wet method has burnt out Superlight ceramsites, but embryo material moisture content itself is high, has a large amount of vapor to go out in drying process
It is existing, so that product is cracked, intensity is relatively low, and water absorption rate is higher, and technique is more complex；The flyash such as Du Xin, clay and sludge dry method
Burn out high-strength ceramic granule, but cost is higher, and current clay has become China and needs resources to be protected.Therefore, existing
The method for producing haydite is not ideal enough.
Invention content
The present invention provides a kind of method with cow dung dry method baking ceramsite, solve because occurring in the drying process big
Amount vapor and make that haydite density is big, water absorption rate is higher, compression strength is relatively low, and preparation method is complicated, and cost is higher, with country
The technical problems such as the clay resource of protection.And raw material is waste, it can be achieved that refuse reclamation, while being replaced with bentonite glutinous
Soil has saved resource.
The technical scheme is that：A method of it is described to fire pottery with cow dung dry method with cow dung dry method baking ceramsite
The method of grain is as follows：
Step1, batch mixing；Auxiliary material cow dung is added in major ingredient bentonite, forms material, which includes bentonite, cow dung,
Bentonite, cow dung are 4 by weight：1 ratio is stirred；Cow dung used is the discarded cow dung in vaccary, and cow dung is existed
It dries at 100~110 DEG C, is then crushed with pulverizer, then the cow dung that size is 80~120 mesh is filtered out with sieve；
Step2, granulation；By the material mixed powder compressing machine compression moulding, briquetting pressure is 6.5~8.0Mpa,
Dwell time is 20~35s, is pressed into a diameter of 30mm, the cylinder of a height of 10mm；
Step3, pretreatment；The material of compression moulding is placed in crucible, then is moved into Muffle furnace, temperature be 300~
Puffing 10~30min is dried at 400 DEG C；
Step4, high-temperature roasting；So that Muffle furnace is warming up to 1180~1220 DEG C, by dry it is puffing after material constant temperature burn it is swollen
10~20min；
Step5, cooling；By the material cooled to room temperature of high-temperature roasting, haydite finished product is obtained.
The beneficial effects of the invention are as follows：
Haydite density that the present invention burns out is small, portion's hole is more, form and ingredient are uniform, and intensity is high, wear-resistant, and has
Good corrosion resistance, freeze-proof, shock resistance and insulating (heat preservation, heat-insulated, sound insulation, moisture resistance), density, resists water absorption rate
Compressive Strength meets national standard.Preparation method is simple, at low cost, it is easy to accomplish continuous production, product quality are stablized, do not polluted
It is environment, corrosion-free, and raw material is waste, it can be achieved that refuse reclamation, while clay is replaced with bentonite, save resource.
