Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of glass tempering furnaces, specifically a rapid heating glass tempering furnace. Background Technology
[0002] A tempering furnace is a device that produces tempered glass using physical or chemical methods. It includes two types: physical tempering equipment and chemical tempering equipment. Physical tempering equipment uses a technique of heating and then rapidly cooling flat glass to create compressive stress on the surface of the cooled glass and tensile stress inside the glass, thereby increasing the strength of the glass and turning ordinary annealed glass into tempered glass.
[0003] However, in existing glass tempering furnaces, the glass is first fed into the furnace by a conveyor belt, and then heated by heating wires. Although the asbestos mesh provides some insulation during the heating process, the limited sealing still makes it easy for the heat generated by the heating wires to dissipate, resulting in heat loss and reducing the rate of glass heating. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, this utility model provides a rapid heating glass tempering furnace, which effectively solves the problem of heat loss in the current glass tempering furnace.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a rapid heating glass tempering furnace, comprising a furnace body, a sealing mechanism on the outside of the furnace body, a heating mechanism inside the furnace body, openings on both sides of the furnace body, multiple support rollers rotatably connected at equal intervals inside the furnace body, and two symmetrical ventilation openings on the outside of the furnace body.
[0006] The sealing mechanism includes a U-shaped plate fixed to the top of the furnace body. A drive motor is fixedly installed on the inner side of the U-shaped plate. A double-acting screw is fixedly connected to the drive motor. The end of the double-acting screw away from the drive motor is rotatably connected to the U-shaped plate. Two guide plates are symmetrically threaded onto the outer side of the double-acting screw. A guide post is fixedly connected to the inner side of the U-shaped plate. Both guide plates are movably sleeved on the outer side of the guide post. A U-shaped round rod is fixedly connected to the top of both guide plates. A lifting plate is movably sleeved on the outer side of both U-shaped round rods. A bracket is fixedly connected to the side of the two lifting plates that is far from each other. A sealing plate is fixedly connected to the bottom of both brackets. The furnace body is located between the two sealing plates.
[0007] Preferably, the bottom of the lifting plate is fixedly connected to an abutment post, which is located above the guide plate.
[0008] Preferably, a support plate is fixedly installed on the inner side of the U-shaped plate, the support plate is fixedly sleeved on the outer middle of the guide column, a two-way screw rod passes through the support plate and is rotatably connected to the support plate, a cylinder is fixedly connected to the top of the support plate, a top plate is fixedly connected to the output end of the cylinder, and both lifting plates are movably sleeved on the outer side of the top plate.
[0009] Preferably, the heating mechanism includes a U-shaped tube located inside the furnace body. Both ends of the U-shaped tube are fixedly connected to hollow plates. Heating wires are provided inside the two hollow plates. Multiple air outlets are provided on the side of the two hollow plates that are close to each other. A connecting pipe is fixedly connected to the U-shaped tube. The end of the connecting pipe away from the U-shaped tube extends to the outside of the furnace body and is fixedly connected to an air inlet. A fan is provided inside the air inlet.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. The cooperation between the cylinder, top plate, lifting plate, U-shaped rod and bracket facilitates the descent of the two sealing plates. The cooperation between the drive motor and the double-acting screw, as well as the guide plate and guide column, facilitates the two sealing plates to come close to each other and fit against the furnace body, thereby blocking and sealing the two openings and preventing heat loss from the furnace body.

Multiple air outlets 302 are provided on the side of each hollow plate 303 that is close to each other. A connecting pipe 304 is fixedly connected to the U-shaped tube 301. The end of the connecting pipe 304 away from the U-shaped tube 301 extends to the outside of the furnace body 1 and is fixedly connected to an air inlet duct 305.
