Description
Technical field
The present invention relates to building material field, and in particular to a kind of Ardealite block brick microwave drying process.
Background technology
Ardealite is a kind of solid waste, is mainly derived from phophatic fertilizer production process.At present, ardealite utilization rate is relatively low,
It is larger to ambient contamination mainly based on stacking.Ardealite is used to make building block brick, can both realize solid waste
Recycling, and can are beautified the environment.Ardealite is chronically at dampness, has harmful effect, main table to Ardealite block brick
It is now：Intensity decreases, the raw bacterium in surface, return frost etc..Thus Ardealite block needs to dry in a short time after shaping.And in reality
In production process, Ardealite block yield is limited by drying time is long, and Ardealite block brick stoving process is still immature.
The more difficult drying of Ardealite block, filled main reason is that the multi-pore structure of ardealite causes Ardealite block to contain large quantity of moisture
Reprimand is in pore.Gypsum block drying technology scheme application at present at present it is most be mainly tunnel type drying technique.Tunnel
Road formula stoving process can realize batch production.Existing tunnel formula stoving process exist floor space is larger, drying effect by
The problems such as being restricted to length of tunnel.Problem be present for existing stoving process, the present invention proposes microwave drying process being incorporated into
In ardealite drying course, to improve drying efficiency.How microwave drying process is incorporated into ardealite drying course, simultaneous
While caring for economic benefit, make drying course more efficient, be that the present invention needs to solve the problems, such as.
The content of the invention
The present invention provides a kind of Ardealite block brick microwave drying process, mainly solves existing tunnel formula stoving process, dries
Do the problems such as inefficient and drying effect is restricted by length of tunnel.The present invention can be realized under shorter length of tunnel, i.e.,
Excellent drying effect can be obtained, saves space, reduces land used cost.
The technical solution adopted by the present invention is：
A kind of Ardealite block brick microwave drying process, comprises the following steps：
Step 1：Ardealite block brick after shaping is being dried, first time microwave is carried out after drying；
Step 2：Ardealite block after first time microwave is dried, second of microwave is carried out after drying；
Step 3：Ardealite block after second of microwave is dried, third time microwave is carried out after drying；
Step 4：Ardealite block after third time microwave is dried；
Step 5：Gypsum block after drying is placed under natural conditions and dried.
Preferably Step 1: the drying temperature described in two and three is 60 DEG C -90 DEG C, drying time 30min-60min.
Preferably Step 1: the microwave time described in two and three is 1min-10min, microwave frequency 2400Hz-
2500Hz。
Compared with prior art, it is an advantage of the invention that：1st, the present invention solves tunnel type drying kiln drying effect by its length
The problem of restriction, realize and higher drying effect is can be achieved with shorter tunnel, so as to cost of saving the area；2nd, this technique
Described microwave generation system belongs to green energy resource based on electric energy, it is possible to reduce the discharge capacity of carbon dioxide in production process,
Reduce pollution.
