Abstract

The utility model relates to a directional heating resistance furnace which comprises a furnace body which is provided with a furnace cavity, heating elements which run through the furnace cavity and are arranged on the lower part of the furnace body, and a thermocouple which is fixed on the inner wall on the upper part of the furnace cavity of the furnace body. The utility model also comprises insulators, wherein, one sides of frame structures of the insulators are opened, and the heating elements are arranged inside the frame structures of the insulators. A great part of each heating element of the utility model is surrounded by each insulator which is made of heat-insulating materials, and heat is concentrated and transmitted by a part of the heating element without heat-insulating materials; the heat of the heating elements is concentrated to required directions and combined with an appropriate radiating structure in the furnace, thereby an aim of directional localized heating is reached. Moreover, the insulators of the heating elements can be lengthened, thereby directional localized heating can be performed on a plurality of or dozens of materials which need heating.

Description

The directed heater of a kind of resistance furnace

Technical field

The utility model relates to heater, the directed heater of particularly a kind of resistance furnace.

Background technology

Owing to the restriction of power and the needs of insulation, a large amount of insulating bricks and refractory brick are arranged in the furnace construction in traditional resistance-heated furnace, to reach the purpose that stove heats up.The stove of this structure can not reach the purpose of local orientation's heating in stove.The method that is commonly used to directed heating has the directed heating of infrared ray, the directed heating of halogen light modulation and laser orientation heating etc., and the induction coil of intermediate frequency or high frequency also can reach the purpose of local heat, widely applies in temperature gradient furnace and zone-melting heating furnace.These orientations or local heat measure are general only to the single body heating, and a plurality of objects are heated difficulty simultaneously.

Summary of the invention

The purpose of this utility model is to design the directed heater of a kind of resistance furnace, the heat of heater can be focused on the direction that needs.

For achieving the above object, the technical solution of the utility model is, resistance furnace is used in a kind of directed heating, comprise, and body of heater, it has a burner hearth; Heater runs through burner hearth and is arranged at the body of heater bottom; Thermocouple is fixed in the burner hearth of the furnace body upper inside wall; Also comprise, insulator, its shaped as frame structure, a side opening, heater are arranged in the insulator shaped as frame structure.

Again, body of heater described in the utility model outwards is followed successively by refractory brick, insulating brick, heat-preservation cotton, furnace shell from the burner hearth cavity.

Described insulator is a square frame shape.

The beneficial effects of the utility model

Heater of the present utility model is most of to be surrounded by the insulator of making of heat-insulating material, heat is concentrated and is sent by the part that does not have heat-insulating material, the heat of heater focuses on the direction that needs, and combines with radiator structure suitable in the stove, to reach the purpose of directed local heating; In addition, the insulator of heater can extend, and therefore can need the material of heating to carry out the directed local heating to many or tens of.

Description of drawings

Fig. 1 is the structural representation of the utility model one embodiment;

Fig. 2 is the A-A enlarged diagram of Fig. 1.

The specific embodiment

Referring to Fig. 1, Fig. 2, resistance furnace is used in directed heating of the present utility model, comprise, and body of heater 1, it has a burner hearth 100, and it outwards is followed successively by refractory brick 101, insulating brick 102, heat-preservation cotton 103, furnace shell 104 from burner hearth 100 cavitys; Heater 2 runs through burner hearth 100 and is arranged at body of heater 1 bottom; Thermocouple 3 is fixed in burner hearth of the furnace body 100 upper inside wall; Insulator 4, its square frame shape structure, a side opening 401, heater 2 are arranged in the insulator 4 shaped as frame structures, are supported by brigade brick 5.

The heat of heater 2 is dispersed from insulator 4 one side openings 401, realizes directed heating.

The utility model focuses on the direction that needs by the heat with heater, combines with radiator structure suitable in the stove, realizes the directed local heating; And, can realize the mass processing to the object that needs the directed local heating.
