Abstract
The invention relates to a chamber type electric furnace which comprises a furnace body and a furnace door. The furnace door is arranged on the furnace body, air cylinders enabling the furnace door to move vertically are arranged on the two sides of the furnace door, the furnace door and the furnace body are in sliding connection, the furnace body comprises an outer shell and an inner shell, a vacuum clearance is arranged between the outer shell and the inner shell, the inner wall of the inner shell is covered with heat resistant bricks, heating elements are arranged between the heat resistant bricks on the two side faces of the inner wall of the inner shell, two parallel vertical heat insulation plates are fixed to the top face of the inner wall of the inner shell, and a clearance is arranged between the lower ends of the heat insulation plates and the bottom face of the inner wall of the inner shell. The air cylinders are adopted by the chamber type electric furnace to push the furnace door, labor is saved, heat transfer is led through the heat insulation plates additionally arranged in the furnace body, the heating effect is more even, and due to the fact that a vacuum layer is additionally arranged between the outer shell and the inner shell, the heat preservation effect is improved.
Description
Technical field
The present invention relates to Equipment for Heating Processing field, particularly a kind of chamber type electric resistance furnace.
Background technology
Resistance furnace is that heat treatment industry uses comparatively frequently with a kind of Equipment for Heating Processing, be mainly to utilize electric current to make the heating element heater evolution of heat of resistance furnace inside, thereby workpiece or the material realized body of heater inside heats.
Also there is refractory brick to carry out heat insulation and insulation although the body of heater of traditional resistance furnace is inner, but do not reach desirable effect.Because hot-air moves upward, so when the workpiece in body of heater is heated, the workpiece in top is better than the workpiece heating effect of below, make various test datas uneven thereby cause a collection of workpiece because heating is inhomogeneous again.In prior art, what fire door generally adopted is that the method that manual rotation chain gear transmission fire door rises or declines realizes unlatching or closes fire door, and this mode is labor intensive relatively.
Summary of the invention
The technical problem to be solved in the present invention is: in order to overcome the deficiencies in the prior art, provide a kind of automaticity high, and simple to operate, safe chamber type electric resistance furnace.
The technical solution adopted for the present invention to solve the technical problems is: a kind of chamber type electric resistance furnace, comprise body of heater and fire door, described fire door is arranged on body of heater, described fire door both sides are provided with the cylinder that can make fire door move up and down, fire door and body of heater are slidably connected, described body of heater comprises shell and inner casing, between described shell and inner casing, be provided with vacuum gap, on the inwall of described inner casing, be coated with heat resisting brick, between the heat resisting brick of the inwall two sides of described inner casing, be equipped with heating element heater, on the inwall end face of described inner casing, be fixed with two vertical thermal insulation boards, the end face sealing of described thermal insulation board upper end and inner casing inwall, between the bottom surface of described thermal insulation board lower end and inner casing inwall, there is gap.
Thermal insulation board is arranged on to the both sides in stove, just to heating element heater, the heat that heating element heater is sent after energising cannot be directly delivered to body of heater middle part, but along thermal insulation board from top to bottom, go out along the gap between thermal insulation board lower end and the bottom surface of inner casing inwall, then transmit from bottom to top, make the workpiece in body of heater be subject to ratio of specific heat originally more even.
In order to improve heat insulation effect, described body of heater and fire door junction are provided with sealing ring.
For heat resisting brick is sticked together better, soft sticky bonding by fiber between described heat resisting brick.
In order to increase inner heating space, described two thermal insulation boards are symmetrical, are separately positioned on the two ends of the inwall end face of inner casing.
The invention has the beneficial effects as follows: this chamber type electric resistance furnace is by adopting cylinder to push fire door, save labour, dominated the transmission of heat by set up thermal insulation board in body of heater, made heating effect more even, by set up vacuum layer between shell and inner casing, improve heat insulation effect.
