Abstract
The utility model discloses a closed ceramic thermostatic electric furnace. An insulating epoxy board is fixed at the top of one case and is provided with four columns; a saddle is arranged at the top of the columns. The periphery of the saddle is provided with clamps and a ceramic platform covers the saddle. The edge of the ceramic platform is clamped by the clamps. An electric heating wire made of winded ceramic cotton is arranged on the saddle; temperature sensing probe heads are respectively arranged under the saddle and on the electric heating wire. An isolation cover is arranged above the insulating epoxy board; thermal insulation materials are filled in the isolation cover. Thermal insulation materials are arranged under the saddle and at the upper part between the clamps. Insulting ceramic cotton is underlaid under the electric heating wire and a temperature controlled circuit board is arranged in the case. A temperature display is arranged on the board of the case. The utility model has the advantages of stable temperature, low heat energy waste and high heat efficiency.
Description
Technical field
The utility model relates to the electrothermal stove that adds that a kind of laboratory uses.
Background technology
The existing electrothermal stove that adds generally all is naked light at present, and is both dangerous, and energy consumption is big again, and domestic existing pottery electric furnace does not mostly reach desired temperature, does not still reach the practical stage.
Summary of the invention
In order to solve the problem that aforementioned electric furnace exists, the utility model provides a kind of both safety, save the ceramic closed constant temperature electric furnace of energy consumption again, it is to fix an insulating epoxy plate at a box body top, four root posts are installed on the epoxy plate, a saddle is fixed on the column top, the saddle periphery is fixed with clamping plate, one ceramic table top is placed on the saddle top, and ceramic mesa edge is clamped by clamping plate, is furnished with the heating wire of the cotton coiling of insulating ceramics on the saddle, below the saddle and be respectively arranged with temperature sensor probe above the heating wire, be provided with temperature control circuit board in the box body, be provided with temperature display and temperature adjustment turn-knob before the box body panel, above the insulating epoxy plate, cage is arranged, be filled with the heat-insulation and heat-preservation material in the cage, below saddle and above the clamping plate middle part, be filled with the heat-insulation and heat-preservation material, below heating wire, be lined with the insulating ceramics cotton; The advantage of the closed constant temperature electric furnace of this pottery is, temperature stabilization, its error is ±≤2 ℃, with the heating wire combustion chamber that high temperature fiber and general fiber turn to, combustion chamber short time temperature can reach 800 ℃, because ceramic table top has sealed combustion chamber, the temperature Centralized that makes combustion chamber is on ceramic table top, below combustion chamber, the heat-insulation and heat-preservation material is arranged again, so heat energy loss is very little, thermal efficiency height.
