Abstract
The utility model provides a ceramic closed constant temperature electric furnace, which comprises a control box, wherein a circuit board is arranged in the control box, four columns are erected on the control box, a lug boss is fixed on the columns, electric heating wires are distributed on the lug boss, a ceramic table-board covers the lug boss, and the periphery of the ceramic table-board and the bottom of the lug boss are clamped and closed by a metal plate, thereby the closed ceramic constant temperature electric furnace is formed. The electric heating wires are woven and wrapped by silicate fiber and then sintered at a high temperature to enable the silicate fiber to seal the electric heating wires. The lug boss arranged on the columns is the metal plate, and the plate is provided with anti-deformation square holes. The electric furnace has the advantages that the temperature is steady, and the error is minus/plus 2 degrees centigrade (DEG C); since the electric heating wires are woven and wrapped by silicate fiber and then sintered at a high temperature to enable the silicate fiber to seal the electric heating wires, the electric heating wires are not contacted with air, so that the electric heating wires can achieve a high temperature of 800 DEG C and is difficult to damage; and since a closed furnace core is arranged below the ceramic table-board, the temperature of the furnace core is centralized on the ceramic table-board, so the temperature of the table-board can reach up to more than 550 DEG C.
Description
Technical field
The utility model relates to a kind of electric furnace that heats usefulness.
Background technology
The present electrothermal stove that adds generally all is naked light, and is both dangerous, and energy consumption is big, and particularly temperature does not reach requirement, particularly for ceramic electric furnace, and the temperature requirement height, at present, domestic still do not have a kind of temperature of ceramic electric furnace can reach more than 550 ℃.
Summary of the invention
For solving the problem of aforementioned existence, the utility model is for the closed constant temperature electric furnace of a kind of pottery, and this electric furnace comprises a control cabinet, and circuit board is arranged in the control cabinet, erect four root posts on the control cabinet, fix a boss on the column, be furnished with heating wire on the boss, it is characterized in that, the boss top is covered with ceramic table top, periphery and boss bottom are clamped sealing by metallic plate around the pottery table top, constitute closed ceramic thermostatic electric furnace.
Described heating wire holds the back high temperature sintering with silicate fiber braiding, makes silicate fiber sealed electrical heated filament, is lined with the insulating ceramics cotton below the heating wire.
Circuit board in the described control cabinet is connected with temperature sensor in the electric furnace, and circuit board also is connected with LCDs on the control cabinet panel, the real-time temperature of demonstration electric furnace, and cut off the electricity supply when making ceramic table top temperature above 551 ℃.
Boss on the described column is a metallic plate, and distortion-free square hole is arranged on the plate.
The utility model has the advantages that, temperature stabilization, error is ± 2 ℃, because heating wire holds braiding back high temperature sintering with silicate fiber, makes silicate fiber sealed electrical heated filament, and heating wire is not contacted with air, thereby can make heating wire reach a high temperature 800 ℃, and heating wire is not fragile.Because ceramic table top below is the combustion chamber of sealing, makes the combustion chamber temperature Centralized in ceramic table top, make the table top temperature can be, and programming rate be also express up to more than 550 ℃, electric furnace is warmed up to 550 ℃ and only needs 16 minutes under the normal temperature state; In addition, because boss has the anti-deformation hole, so boss can not be out of shape under long-time high temperature yet.
Description of drawings
Accompanying drawing 1 is a front view of the present utility model.
Accompanying drawing 2 is front views of ceramic table top.
Accompanying drawing 3 is side views of Fig. 2.
The number in the figure explanation:
The 1-control cabinet, 2-column, 3-cage, 4-metallic plate, 5-boss, 7-heating wire, 8-pottery table top, 9-insulating epoxy plate, 10-display screen, 11-power switch, 12-press button, 13-power supply indicator, the indication of 14-temperature, 15-electric furnace footing, 16-temperature adjustment turn-knob.
The specific embodiment
See also shown in the accompanying drawing 1,2,3, the utility model comprises a control cabinet 1, in the control cabinet 1 circuit board is arranged, erect four root posts 2 on the control cabinet 1, fix a boss 5 on the column 2, be furnished with heating wire 7 on the boss 5, boss 5 tops are covered with ceramic table top 8, periphery and boss bottom are clamped sealing by metallic plate around the pottery table top 8, constitute closed ceramic thermostatic electric furnace.
The braiding of described heating wire 7 usefulness silicate fibers holds the back high temperature sintering, makes silicate fiber sealed electrical heated filament, is lined with the insulating ceramics cotton below the heating wire.
Circuit board in the described control cabinet 1 is connected with temperature sensor in the electric furnace, and circuit board also is connected with LCDs 10 on the control cabinet panel, the real-time temperature of demonstration electric furnace, and cut off the electricity supply when making ceramic table top 8 temperature above 551 ℃, to protect ceramic table top.
Temperature adjustment turn-knob 16 on the described control cabinet panel has scale, can be transferred to the furnace temperature that needs.
At the top of control cabinet 1, be coated with epoxy insulating board 9, insulation board 9 usefulness cages 3 cover, and are filled with insulation material in the cage 3.
