The furnace is characterized in that: the multiple hydrothermal kettles can be accommodated in a single crystal growth furnace, the temperature interference of upper and lower heating zones in hydrothermal equipment is prevented by a temperature isolation plate, and the furnace has a simple structure, controls temperature accurately and is energy-saving and environment-friendly. According to the technical scheme, the novel hydrothermal crystal growth furnace capable of accommodating the multiple hydrothermal kettles comprises a graphite hearth capable of accommodating the multiple hydrothermal kettles, the temperature isolation plate, an electric furnace heating wire, a temperature measurement and control device, a top thermal insulation cover, a thermal insulation filler and a shell.
Description
Technical field
The present invention relates to a kind of development of holding the novel hydrothermal method crystal growing furnace of a plurality of water heating kettles, belong to Hydrothermal Growth crystal technical equipment field.
Background technology
The Hydrothermal Growth crystal is meant: pour mineralizer solution into water heating kettle, the baffle plate with holes in the water heating kettle is divided into two zones with the water heating kettle liner, and lower area is called dissolve area; Place the hydrothermal growth culture material, last zone is called the vitellarium, places seed crystal; Through temperature control technique, make dissolve area be in the condition of high temperature, and the vitellarium is in low-temperature condition; The saturated solution of dissolve area is transported to the vitellarium through the aperture on the baffle plate like this, because temperature reduces, saturated solution becomes supersaturated solution; Oversaturated part will be separated out on seed crystal, make seed crystal constantly grow up.
There are two big defectives at present traditional hydro-thermal crystal growing furnace; First furnace tube can only be placed a water heating kettle; Therefore there is the low and bigger problem of energy consumption of growth efficiency; It two is to go up the heating zone to have the temperature interference problem with following heating zone the decline of heating zone temperature-controlled precision about usually causing.Therefore, if develop a kind of crystal growing furnace of placing a plurality of water heating kettles,
To in energy-conserving and environment-protective, increase substantially growth efficiency.Is but a difficult problem of developing this equipment existence: the temperature control accuracy that how could guarantee all water heating kettles? How just can prevent the temperature interference between heating zone and the following heating zone?
In order to improve the temperature control accuracy of water heating kettle; The present invention intends and adopts the extraordinary graphite material of heat conductance to do furnace tube; In order to prevent or to reduce up and down the temperature of heating zone and interfere; The present invention's plan level between last process furnace silk and following process furnace silk is laid an annular thermal insulative board, and the thermal insulative board material adopts the very poor lagging material of heat conductance.
Summary of the invention
The invention provides a kind of novel hydrothermal method crystal growing furnace that holds a plurality of water heating kettles; Its characteristics are can hold a plurality of water heating kettles in the single crystal growing furnace, and use thermal insulative board to prevent the temperature of heating zone interference up and down in the water heating apparatus, and are simple in structure; Temperature control is accurate, energy-conserving and environment-protective.The present invention adopts following technical scheme: comprising: graphite burner hearth, thermal insulative board, heating electric stove wire, temperature regulating device, top insulation cover, insulation filler and housing.It is characterized in that: use the very high graphite of thermal conductivity coefficient to do furnace tube, this furnace tube can hold a plurality of water heating kettles, peripheral having heaters of furnace tube and measuring and controlling temp system, and well heater uses electric stove wire, globars or Si-Mo rod material.The insulation filler is filled between warming plate and the furnace tube, and the insulation filler is a pearlstone.Warming plate is adjacent at the furnace shell inwall, and thermal insulative board is positioned over up and down between the heating zone, and warming plate and thermal insulative board all adopt pure aluminium silicate, Calucium Silicate powder, Natural manganese dioxide, beryllium oxide, zirconium white, in the silit one or any several kinds.The steel plate of housing after by 3mm processed.Thermometric and temperature controlling system adopt thermopair and temperature controller combination.
The novel hydrothermal method crystal growing furnace that can hold a plurality of water heating kettles uses step to comprise:
1. a plurality of water heating kettles are positioned in the graphite furnace tube, cover the top insulation cover.
2. will go up temperature control inserts in the graphite furnace tube with following temperature-control heat couple.
3. the temperature control program is set, and through 6 hours intensification, last heating zone arrived holding temperature with following heating zone, and the temperature of following heating zone is higher than the heating zone.
4. passed through certain soaking time, cooling process has been set, let the body of heater cool to room temperature.
5. open the top insulation cover, hang out water heating kettle.
