Description
Technical field
The present invention relates to the transmission of solid material, technical field of drying, and in particular to the useless silicon mud of Buddha's warrior attendant wire cutting is granulated into
Transhipment, the drying of the silicon particle of type.
Background technique
The dry technology of solid material is widely used in numerous industrial productions.Traditional sunning method be it is most easy,
Economic dry materials method, but require broad place and rate of drying slowly takes a long time, working efficiency is low, also by weather
Equal many factors influence, therefore difficulty is used in industrial circle.In photovoltaic industry, silicon wafer cuts (monocrystalline silicon, polycrystalline
Silicon) a large amount of cutting silicon powder can be generated, it is universal with Buddha's warrior attendant line cutting technology, silicon wafer cutting form mix large quantity of moisture,
The useless silicon mud of a large amount of silicon powders and a small amount of impurity.Since the value high (market price 8 ~ 100,000 yuan/ton) of silicon powder, particle are thin (average
Partial size is less than 2.5 microns), it is allowed to be stacked and not only results in the wasting of resources and have very big pollution to environment, be to resource
Change the waste of processing.For the ease of needing useless silicon mud drying and moulding to the cutting silicon powder progress resource regeneration in useless silicon mud,
In favor of in regenerative process transport, feed intake.In order to improve the added value of useless silicon mud reconstituted product, the processing of useless silicon mud is reduced
Cost improves the main target that treatment effeciency is relevant enterprise, develops advanced, efficient, energy-efficient useless silicon mud dry technology and work
Skill has important meaning.
There are many drying means of country's solid material at present, such as micro-wave drying method, expansion drying, air-flowing type are dry.Its
The energy utilization rate of middle micro-wave drying method is higher, dry materials are uniform, but the silicon particle after being granulated can be made broken and greatly reduced
Balling ratio (only about 15%), is unfavorable for subsequent material transportation and resource regeneration.And expansion drying is mainly used for powder drying, institute
The temperature needed is higher, can go bad because of high-temperature oxydation silicon powder.Air-flowing type dry (vibrated fluidized bed, spray dryer) is to make solid
Particle is suspended in drying in heat medium, is also easy to produce silica soot, easily causes dust concentration excessively high in this way and explode.
In addition, traditional material transmission mostly uses greatly the mode of manual handling, speed is slow, low efficiency, personnel labor intensity
It is larger, the high production cost of enterprise.To overcome problem above, it is necessary to using based on mechanical equipment, it is artificial supplemented by sender
Formula.Common transmission equipment has roller, belt, chain delivery equipment and row to hang, hydraulic tracting vehicle etc..These transmission devices behaviour
Make simplicity, run smoothly, and security performance is high, this is carried out for material, and convenient, safe, quickly transport provides equipment guarantee.
In order to realize material efficiently transmission during granulation, dry etc., rationally designed, by effective group of various transmission equipments
It closes, production efficiency could be improved.
Summary of the invention
It is an object of the invention to overcome in the prior art, provide a kind of drying effect is good, operational efficiency is high,
Transmission, drying means and the device for the silicon particle that safe and reliable useless silicon mud granulating and forming obtains.
For achieving the above object, the present invention specifically adopts the following technical scheme that
A kind of transmission of useless silicon mud granulating and forming silicon particle, drying means, it is characterised in that include the following steps:
Step 1: entering disk, and silicon particle that granulating and forming obtains is conveyed obliquely using belt feeder, then by buffer board slide to
In material disc；
Step 2: the double-layer staggered formula of silicon particle in material disc is stacked, is then placed on stainless steel Conveyor by restocking
It is conveyed；The height for adjusting material frame is hung using row, and material disc is transferred to material frame not in the end of Conveyor
With in the bed of material；The material frame row of full charging tray, which is hung, to be transferred on ground guide, is drawn using track hydraulic tracting vehicle uniform rectilinear
Enter drying chamber；
Step 3: dry, material frame double discharge arranged side by side in sealing drying chamber carries out static dry；
