Description

High temperature bench vehicle type electrical resistance furnace

Technical field

The utility model belongs to the industrial processes electric furnace, is specifically related to a kind of high temperature bench vehicle type electrical resistance furnace.

Background technology

Existing bench vehicle type electrical resistance furnace is to improve among a small circle by old-fashioned structure of the sixties substantially, structural design is unreasonable, energy consumption is high, intensification is slow, heat-insulating property is poor, oven door sealing is not tight, chassis and body of heater can't effectively seal, the cloth silk is unreasonable, furnace temperature is inhomogeneous, temperature-controlled precision is low, and furnace temperature is low, can't satisfy to connect 1200 ℃ of heat treatments or sintering process needs.

Summary of the invention

The purpose of this utility model is to provide a kind of high temperature bench vehicle type electrical resistance furnace of good sealing effect, to address the above problem.

The technical solution of the utility model is: high temperature bench vehicle type electrical resistance furnace, it comprises body of heater, heat-insulation layer of establishing in the body of heater and furnace lining, establish on the furnace lining and put a brick, put on the brick and establish heater element, the base plate in the body of heater is divided into heater element, connect fire door and fire door hoisting mechanism on the body of heater, body of heater peripheral hardware chassis, drive unit and track, the chassis periphery is established the automatic sealing device of chassis and body of heater, establishes oven door sealing mechanism on the body of heater.

This stove good sealing effect can automatically be finished multiple Technology for Heating Processing and diamond oil bit sintering process such as quenching to machine components and foundry goods, normalizing, tempering, timeliness.This does not have any pollution to environment, and high energy saving can continuous 1200 ℃ of hot operations, and furnace temperature is even, the temperature-controlled precision height, and sealing is tight, can realize microcomputer-recognized intelligent chemical control system, can precision finish any heat treatment cycle curve and sintering process.

The specific embodiment

As shown in Figure 1, establish fire door hoisting mechanism 8 on the body of heater 1, this mechanism is electronic belt hoisting mechanism, and its end is connected with fire door 18.Establish oven door sealing mechanism 9 on the body of heater 1; Oven door sealing mechanism 9 comprises the oil cylinder 91 that is located on the fire door, articulated linkage 93 on the piston rod 92 of oil cylinder, and hinged shift fork 94 on the connecting rod 93, the other end of shift fork 94 are located in the guide rail 19 on the fire door 18.Connection chain transmission device 12 between the roller 22 that the power intake roller 21 of chassis 20 is adjacent.Establish chassis headstock 11 on the chassis 20.Chassis 20 is located on the track 13.

As shown in Figure 2, heat-insulation layer of establishing in the body of heater 1 14 and furnace lining 5 are established on the furnace lining 5 and are put a brick 6, put and establish heater element 7 on the brick 6, and the base plate 16 in the body of heater 1 is divided into heater element 17.Furnace roof 4 is energy-conservation layer, and it can be efficient light energy saving brick or overall height aluminum fiber furred ceiling.

As shown in Figure 1, 2, the automatic sealing device that the chassis periphery is established chassis and body of heater comprises the skewed slot steel guide rail 23 that body of heater 1 is divided into, and sand cutter 24 is established in body of heater 1 following peripheral, the sand cutter 25 that chassis 20 peripheries are established; Chassis 20 peripheries are established sand launder 10, and moving sand launder 10 is provided with the slide mechanism 26 relative with skewed slot steel guide rail 23.Above-mentioned chassis 20 peripheries and body of heater 1 following peripheral are three limits.

The automatic sealing device sealing principle that the chassis periphery is established chassis and body of heater is: in the time of in chassis sails stove into, under the effect of the moving 45 ° of slide mechanisms 26 of husky groove of individual skewed slot steel guide rail 23 under body of heater and chassis, moving husky groove 10 will rise automatically, with on body of heater 1 and the chassis 20 2 decide the sand cutter tightly to be sealed in sand seal close in sand sealing groove, seal extremely tight; When chassis rolls away from, husky groove will descend automatically, deviate from two limits and decide the sand cutter.Do not scrape a dot encapsulation sand, owing to without any need for the electrical equipment interlocking, also do not need power, it is reliable to be perfectly safe, and very effective, only this invention will reduce electric furnace 15% heat loss, and temperature uniformity is improved greatly.

Connection chain transmission device 12 can solve the skidding of chassis 20 effectively between the roller 22 that the power intake roller 21 of chassis 20 is adjacent.

The oil cylinder 91 of oven door sealing mechanism 9 is located at outside the fire door both sides groove steel rail of body of heater 1, and every limit oil cylinder drives two shift forks with connecting rod, makes fire door and fire door compress sealing, has thoroughly solved medium-and-large-sized oven door sealing hard nut to crack.

As shown in Figure 3,45 ° of oblique rails 30 of weldering in the fire door both sides designs channel-section steel descend fire door 18 to rely on 45 ° of inclined-planes when closing that deadweight compresses sealing with fire door by fire door, during rise because 45 ° of tracks, fire door laterally breaks away from fire door earlier and makes progress, can not produce friction with masonry like this.
