Description
Technical field
The present invention relates to silicon carbide waste mortar process field, be specifically related in a kind of silicon chip waste mortar for wire cutting to remove silicon and
Silicon dioxide device.
Background technology
Photoelectric technology is an important sources of cleaning electric energy, and the market demand of photovoltaic cell grows beyond 25% every year.
In the cost structure of battery, silicon chip accounts for more than the 35% of its cost.In order to reduce mechanical stress during silicon chip cutting processing
And thermal stress, the stability of security system cutting process, the most first by high for hardness, little and centralized particle diameter the carborundum of granularity is micro-
Powder joins according to a certain percentage with in the Polyethylene Glycol (PEG) water solublity as primary raw material or oil soluble liquid, is configured to all
Even stable silicon chip cutting fluid.Along with the carrying out of cutting, carborundum hexagonal profile is passivated, until trending towards spherical.Additionally
The cutting heat produced in cutting process, also results in the rotten of cutting liquid itself, makes cutting power reduce, and causes the silicon wafer obtained
Sheet deteriorated accuracy, therefore needs constantly to discharge old mortar in working angles and supplements fresh sand slurry.Cutting waste mortar main component
Including SiC, PEG, Si and Fe etc..As important material, carborundum production process is complicated, and energy consumption is big, and price is high., recovery is cut
Cutting the SiC in waste mortar, move in circles use, can improve service efficiency with energy efficient, obtain bigger economic benefit.But
Being possibly together with substantial amounts of silicon and silicon dioxide in waste mortar solid material, the precision of SiC is reclaimed in impact.Silicon and silicon dioxide are permissible
React with alkali (NaOH), generate soluble silicate and gas.
Summary of the invention
For problem of the prior art, it is an object of the invention to provide a kind of silicon chip waste mortar for wire cutting is removed silicon and
Silicon dioxide device.
The technical scheme is that in a kind of silicon chip waste mortar for wire cutting and remove silicon and silicon dioxide device, including stirring
Mixing machine, band filter one, band filter two, washing pool and reaction tank, described blender enters with band filter one
Mouth is connected, and the upper outlet of band filter one is connected with washing pool, is connected with reaction tank bottom washing pool, reaction tank
Outlet is connected with the entrance of band filter two.
Described reaction tank is provided with agitating device, during work, adds NaOH.
Apparatus of the present invention use alkali wash to remove silicon and silicon dioxide in waste mortar, make the silicon in waste mortar solid material and
Silicon dioxide and alkali reaction, generate soluble silicate and remove from material, and to obtain highly purified carborundum, idiographic flow is such as
Under:
1) add water in silicon chip waste mortar for wire cutting be transported to blender mixing；
2) mixed material is separated by band filter one, draw the block one of filter liquor one and solid-state, filter
Going out liquid one and do liquid waste processing, the block one of reservation is containing residual Polyethylene Glycol；
3) block is transported to clear water reserviors, is carried out with water；
4) material after cleaned is transported to reaction tank, adds alkali (NaOH) stirring and makes the silicon in material and silicon dioxide the most anti-
Should, the gas of generation does exhaust-gas treatment；
5) reacted material is transported to band filter two, draws the block two of filter liquor two and solid-state, and filter liquor one is done
Liquid waste processing, the block two of reservation has removed silicon and silicon dioxide；
6) block two is centrifuged dehydration, is transported to microwave dryer and is dried, i.e. can get highly purified carborundum.
Beneficial effect: apparatus of the present invention can well remove the silicon in silicon chip dicing waste mortar and silicon dioxide, obtains
Highly purified carborundum.May use the row such as silicon chip cutting, refractory material, fine ceramics after highly purified carborundum is classified
Industry, has significant industrial application value.

Fig. 1 present invention removes silicon and the structural representation of silicon dioxide device.
Detailed description of the invention
As it is shown in figure 1, a kind of silicon chip waste mortar for wire cutting removes silicon and silicon dioxide device, including blender, belt
Filter one, band filter two, washing pool and reaction tank, wherein blender is connected with the entrance of band filter one,
The upper outlet of band filter one is connected with washing pool, is connected with reaction tank bottom washing pool, reaction tank outlet and band
The entrance of formula filter two is connected.
In the present embodiment, reaction tank is provided with agitating device, during work, adds NaOH.
In the present embodiment, use alkali wash to remove silicon and silicon dioxide in waste mortar, make the silicon in waste mortar solid material
With silicon dioxide and alkali reaction, generating soluble silicate and remove from material, to obtain highly purified carborundum, flow process is such as
Under:
1) add water in silicon chip waste mortar for wire cutting be transported to blender mixing；
2) mixed material is separated by band filter one, draw the block one of filter liquor one and solid-state, filter
Going out liquid one and do liquid waste processing, the block one of reservation is containing residual Polyethylene Glycol；
3) block is transported to clear water reserviors, is carried out with water；
4) material after cleaned is transported to reaction tank, adds alkali (NaOH) stirring and makes the silicon in material and silicon dioxide the most anti-
Should, the gas of generation does exhaust-gas treatment；
5) reacted material is transported to band filter two, draws the block two of filter liquor two and solid-state, and filter liquor one is done
Liquid waste processing, the block two of reservation has removed silicon and silicon dioxide；
6) block two is centrifuged dehydration, is transported to microwave dryer and is dried, i.e. can get highly purified carborundum.
