Inlet and outlet ports are opened at the middle of the left and right sides of the glass tempering furnace body. A fixing groove is opened at the middle of the front surface of the tabletop. Several servo motors are fixedly connected to the middle of the front surface of the glass tempering furnace body. The output ends of the servo motors penetrate the glass. The inner cavity of the glass tempering furnace body is fixedly connected to a transmission roller. Heating wires are fixedly connected to both the upper and lower ends of the left side of the inner cavity of the glass tempering furnace body. An asbestos board is fixedly connected to the inner cavity of the glass tempering furnace body. Conveyor belts are installed on both the left and right sides of the upper surface of the platform. The heating wires are activated by an external controller, allowing simultaneous heating of the top and bottom of the glass plate. The asbestos board provides insulation, preventing heat loss and achieving fast and uniform heating. This solves the problems of slow and uneven heating in existing glass tempering furnaces, which lead to high energy consumption and uneven temperature, affecting product quality.

[0004] The aforementioned patented resistance wire is located inside the furnace body, but the furnace has a certain space. When restarting, it will consume a lot of energy to raise the temperature inside the furnace. This not only consumes a lot of time during operation but also causes a certain amount of resource waste. Therefore, we propose a rapid heating glass tempering furnace. Utility Model Content

[0005] The purpose of this invention is to provide a rapid heating glass tempering furnace to solve the problem mentioned in the background art that when restarting, a large amount of energy is still needed to raise the temperature inside the furnace, which not only consumes a lot of time during operation but also causes certain resource waste.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid heating glass tempering furnace, comprising a tempering furnace body, a warning light, and a heating chamber. The heating chamber is formed inside the tempering furnace body, and a warning light is fixedly installed at one top corner of the tempering furnace body. A circular tube is fixedly installed at the bottom of the inner cavity of the heating chamber. The circular tube includes a storage chamber, a support, a heat insulation layer a, and a heating wire. The storage chamber is formed inside the circular tube, and a support is embedded at the bottom of both ends of the storage chamber. The heating wire is wound around the outer wall of the support. The inside of the circular tube is filled with the heat insulation layer a, and both ends of the circular tube have circular openings.

[0007] Preferably, the top two sides of the tempering furnace body are fixedly connected to pipes, and the pipes are fixedly connected to the blower through fixing sleeves.

[0008] Preferably, the interior of the tempering furnace body includes a heat insulation layer b, a movable air cavity, a clamping plate, and a heat-conducting plate. The movable air cavity is formed inside the tempering furnace body, and the clamping plate is sleeved inside the movable air cavity. The bottom of the clamping plate is fixedly connected to the bottom of the tempering furnace body. The interior of the tempering furnace body is filled with the heat insulation layer b, and the heat-conducting plates are fixedly connected to the four outer walls of the clamping plate.

[0009] Preferably, the heat-conducting plate has an internal cavity filled with silver-plated particles, and the heat-conducting plate is corrugated.

[0010] Preferably, the thickness of the clamping plate is three to five centimeters, and the bottom two sides of the clamping plate are provided with connection ports, which are connected to the circular opening.

[0011] Preferably, the diameter of the active air chamber is five times the inner diameter of the connecting port and the circular port.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By combining the designed circular tube and the heat insulation layer a, the heat generated by the heating wire during operation can be quickly accumulated and stored inside the circular tube. Compared with the existing installation method, this heating method can quickly form and accumulate heat.

[0014] 2. By using a combination of fan and pipe, the airflow inside the active air chamber is continuously driven to move. When moving, the airflow passes through the inside of the circular pipe and carries out heat. Through the airflow, the heat can be quickly transferred to the inside of the heat-conducting clamp, so that the clamp can quickly generate heat. This heating speed is faster than the existing heating method, and one set of heating wires can heat the top and bottom. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a rapid heating glass tempering furnace, including a tempering furnace body 1, a warning light 4, and a heating chamber 2. The heating chamber 2 is opened inside the tempering furnace body 1. The warning light 4 is fixedly installed at one corner of the top of the tempering furnace body 1. A round tube 3 is fixedly installed at the bottom of the inner cavity of the heating chamber 2. The inside of the round tube 3 includes a storage chamber 301, a support 302, a heat insulation layer a303, and a heating wire 304. The storage chamber 301 is opened inside the round tube 3. The support 302 is embedded at the bottom of both ends of the storage chamber 301. The heating wire 304 is wound around the outer wall of the support 302. The inside of the round tube 3 is filled with the heat insulation layer a303. Both ends of the round tube 3 have round openings. Pipes 5 are fixedly connected to the top two sides of the tempering furnace body 1. The pipes 5 are fixedly connected to the fan 7 through a fixing sleeve 6.

[0022] In this embodiment, by setting up the circular tube 3, the radiation distance can be reduced, allowing the interior of the circular tube 3 to quickly generate high temperatures.

[0023] Specifically, the tempering furnace body 1 includes an insulation layer b101, a movable air chamber 102, a clamping plate 103, and a heat-conducting plate 104. The movable air chamber 102 is opened inside the tempering furnace body 1, and the clamping plate 103 is sleeved inside the movable air chamber 102. The bottom of the clamping plate 103 is fixedly connected to the bottom of the tempering furnace body 1. The interior of the tempering furnace body 1 is filled with the insulation layer b101. The heat-conducting plate 104 is fixedly connected to the four outer walls of the clamping plate 103. The heat-conducting plate 104 has a cavity 1041 inside, and the cavity 1041 is filled with silver-plated particles 1042. The heat-conducting plate 104 is wavy. The thickness of the clamping plate 103 is three to five centimeters, and the bottom two sides of the clamping plate 103 are provided with connection ports. The connection ports and the round opening are interconnected. The diameter of the movable air chamber 102 is five times the inner diameter of the connection port and the round opening.

[0024] In this embodiment, after the high temperature is formed, the fan 7 is started, so that the pipe 5 connected to one end of the fan 7 will generate suction, while the other end of the pipe 5 will generate exhaust. This causes the air to circulate. During the circulation, the air will pass through the inside of the circular pipe 3. During the process, the air can heat up quickly. When it is discharged, it can ensure that the hot airflow comes into contact with the clamp 103 quickly, so that the clamp 103 can heat up quickly.

[0025] Working principle:

[0026] Step 1: During the operation, pipe 5 is installed on top of the tempering furnace body 1 and connected to the blower 7.

[0027] Step two: The heating wire 304 is then activated, generating heat. Because the inside of the circular tube 3 is filled with a heat insulation layer a303, the heat generated by the heating wire 304 is stored inside the storage cavity 301. The fan 7 is then started. Upon startup, one end of the tube 5 generates suction, drawing out the gas from the movable air cavity 102. During this high-speed airflow, the heat stored inside the circular tube 3 is drawn out. This heat comes into contact with the heat-conducting plate 104, which is corrugated to increase the contact area with the heated gas. The heat-conducting plate 104 can quickly transfer heat into the interior of the clamping plate 103, and the gas can be discharged through the pipe 5 connected to the other end of the fan 7. When discharged, the gas will enter the interior of the circular tube 3 through the connection port. When the gas passes through the interior of the circular tube 3, the gas can be heated by the heating wire 304. Then it is extracted by the pipe 5 at one end. The interior of the movable air chamber 102 is sealed, which allows the airflow to circulate continuously and carry the heat out of the interior of the circular tube 3. When it is carried out, it can come into contact with the outer wall of the clamping plate 103, so that the heat can be quickly transferred, thus facilitating heating.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
