Technical field
The present invention relates to a kind of method for conveying pressed block of silicon powder and special conveying equipment thereof, be mainly used in the silica flour preparation field of the monocrystalline silicon and the polysilicon that are raw material.
Background technology
Silica flour is a kind of thin small and light particle, easily produces and flies upward and oxidation.In the process of silica flour being purified, can run into a series of problem with monocrystalline or polycrystalline furnace.At first, when vacuumizing, silica flour is easy to be taken away by vavuum pump, loss silicon material, even silica flour is attached on the vacuum pipe, blocking pipe; Secondly, silicon powder particle is small and light, is easy to produce fly upward, and the people is produced very big harm; Moreover the density of silica flour is little, and the disposable charging in the crucible is just few, has not only wasted resource but also inefficiency.So, when purifying, silica flour should be pressed into bulk with monocrystalline or polycrystalline furnace.
Secondly, silico briquette is combined by mechanicals efforts by the graininess silica flour, so it has the following character: more crisp, fall slag easily, have certain compression strength again simultaneously, can bear certain pressure, but can not be subjected to the shearing force effect, can not be impacted.By analyzing the character of above silico briquette; will find when silico briquette is implemented carrying and transportation, to have certain difficulty; for this reason; the necessary cover protective device of designing; should realize the loading of silico briquette easily and unload; can play fixedly silico briquette again, make it in transit can be not defeated and dispersed because being subjected to vibration, impact or shearing force.
Summary of the invention
The technical problem to be solved in the present invention is: for solve silico briquette character more crisp, fall slag thereby carrying and transportation difficult technologies problem easily, the invention provides a kind of method for conveying pressed block of silicon powder and special conveying equipment thereof.
The technical solution adopted for the present invention to solve the technical problems is: a kind of method for conveying pressed block of silicon powder has following steps:
A. pressed block of silicon powder; With hydraulic press silica flour is pressed into silico briquette; Described hydraulic press has drift, mould and the following block of " T " font by Driven by Hydraulic Cylinder, is sealed and matched between the inwall of drift, following block and mould, and the three surrounds the silica flour blanketed zone;
B. the demoulding, put on the shelf; Demoulding frame jacking mould is deviate from silico briquette and following block, and silico briquette is put into the hole of the following protection carriage of special conveying equipment under block supports down;
C. close frame, carrying; Carry out the silico briquette carrying after being combined in last protection bay cover on the following protection carriage that silico briquette is housed;
D. take; Silico briquette is removed to the destination, taken off the protection carriage, take out silico briquette.
A kind of special conveying equipment of aforesaid method for conveying pressed block of silicon powder; comprise that offering going up of several holes respectively protects carriage and following protection carriage; hole on last protection carriage and the following protection carriage is the die cavity of corresponding synthetic ccontaining silico briquette one by one; the shape of die cavity size is adaptive with silico briquette, on protect carriage and following detachable connection of protection carriage.
For each cavity energy that makes protection carriage and following protection carriage just in time lumps together, described going up on protection carriage and the following protection carriage also has the assist location part.
For protection carriage and following protection carriage are fitted together better; be convenient to carrying; the described protection carriage of going up all has at least one group of stiff end that is oppositely arranged with following protection carriage, and device has the securing member that last protection carriage and following protection carriage are detachably linked together on the stiff end.
Aforesaid securing member is bolt, pin or clip.
The invention has the beneficial effects as follows: adopt method for conveying pressed block of silicon powder of the present invention, increased silico briquette in carrying and stability in transit, thereby greatly reduce because the defeated and dispersed phenomenon of silico briquette that vibration or other factors cause can realize carrying, the transportation and long time stored of long distance.Simultaneously, also reduced the defeated and dispersed rate of silico briquette when silico briquette is put into silica crucible.Both save the cost of purification crystal pulling, improved productivity effect again.
