Description

Technical Field

[0001] This utility model relates to the technical field of glass tempering equipment, specifically to a vertical rotary tempering furnace. Background Technology

[0002] Glass tempering is a process that significantly increases the strength of ordinary glass through heat treatment. The main steps are to put the glass into a tempering furnace, heat it to near its softening point, and then blow high-pressure cold air onto both sides of the glass, causing the surface to cool and solidify instantly, creating a stress difference between the inner and outer surfaces of the material, thereby increasing the strength of the glass.

[0003] This process is already very mature in the production of tempered glass. However, when cooling the glass surface, it is necessary to open the furnace to remove the glass. Frequent opening of the furnace will inevitably lead to a large amount of heat loss and energy waste.

[0004] In view of this, the applicant proposes a new tempering furnace equipment that can complete the cooling process inside the furnace, thereby effectively reducing heat loss, improving production efficiency, and also playing a role in energy conservation and emission reduction. Utility Model Content

[0005] Therefore, this utility model provides a vertical rotary tempering furnace to solve the problem of heat loss caused by frequent furnace opening in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model discloses a vertical rotary tempering furnace, including:

[0008] The furnace body has air-cooled fans symmetrically arranged on both sides. The air-cooled fans are adapted to blow air into the furnace body and form heat dissipation convection.

[0009] The rotary working tube is equipped with a lifting cover at the top, and a stacking frame is installed in the middle of the lifting cover. The stacking frame is located at the center of the rotary working tube, and the rotary working tube is rotatably arranged at the axis of the furnace body.

[0010] A heat-conducting base is equipped with thermoelectric batteries at both ends, which are connected to the air-cooled fan circuit. A servo motor is installed in the middle of the heat-conducting base, which is adapted to drive the rotary working tube to rotate.

[0011] The furnace body generates heat and transfers it to the stack within the rotary working chamber. Glass is placed inside the stack. When the glass temperature reaches close to its softening temperature, the rotary working chamber rotates 90 degrees to transfer the heat through the heat-conducting base to the thermoelectric battery. The thermoelectric battery generates current to drive the air-cooling fan to cool the glass.

[0012] Furthermore, the rotary working tube includes:

[0013] The heat insulation tube body has a retaining ring at the top, which is slidably mounted on the top of the furnace body, and a toothed ring is coaxially mounted at the bottom of the heat insulation tube body;

[0014] Two heat conduction grooves are symmetrically arranged on the side of the heat insulation tube, and a heat release port is provided at the bottom of the heat insulation tube.

[0015] Furthermore, the heat-conducting base includes:

[0016] The seat body has a sealing disc in the middle, and the sealing disc is located inside the gear ring;

[0017] The drive gear is located inside the sealing disc and meshes with the gear ring for transmission. The drive gear is coaxially connected to the servo motor for transmission.

[0018] A pair of battery slots, each containing the thermoelectric battery, with the bottom of the battery slots connected to a heat inlet via a heat conduction channel:

[0019] The heat inlet is located on the sealing disc and is adapted to communicate with the heat outlet.

[0020] Furthermore, the air-cooled fan includes a housing, an industrial fan, and a dust removal screen. A pair of housings are installed on both sides of the furnace body. Multiple industrial fans are provided on the back side of each housing, and the dust removal screen is provided on the front side.

[0021] Furthermore, the furnace body includes:

[0022] The heating plate has several electric heating units on the inner side and a heat insulation layer on the outer side.

[0023] The furnace chamber has heating plates on the front and rear sides, and air inlets on the left and right sides. A rotating inner cavity is located in the center of the furnace chamber, and the rotating inner cavity is connected to the heating plates and the air inlets.

[0024] Furthermore, the stacking frame includes slots, a frame body, and fixing screw holes. The lifting cover is fixedly connected to the end of the frame body. Multiple layers of slots are vertically arranged inside the frame body. The fixing screw holes are provided outside the slots. The fixing screw holes are suitable for installing fasteners and fixing the glass in the slots with fasteners.

[0025] Furthermore, a temperature sensor is installed inside the lifting cover, and the temperature sensor is connected to a microcontroller circuit, which in turn is connected to a buzzer circuit.

[0026] Specifically, when the temperature sensor detects that the furnace body temperature is higher than 700 degrees Celsius, the microcontroller drives the servo motor to rotate 90 degrees; when the furnace body temperature is lower than 50 degrees Celsius, the buzzer emits a warning sound.

[0027] This utility model has the following advantages:

[0028] This utility model discloses a vertical rotary tempering furnace with a rotatable working tube installed inside. The furnace body for heating the glass and an air-cooling fan for cooling are arranged orthogonally outside the working tube. When the temperature inside the working tube approaches the soft point of the glass, the working tube rotates 90 degrees, releasing a high-speed airflow through the air-cooling fan to cool the glass. Furthermore, no external power supply is required; the heat inherent in the glass is converted into electricity to drive the air-cooling fan. In contrast, existing technologies require repeated furnace opening and closing to cool the product, resulting in significant heat loss. Therefore, this product has the advantages of high heat utilization and low heat loss compared to existing technologies, and can significantly shorten production time. Attached Figure Description

Detailed Implementation

[0038] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] Please refer to this as well. Figures 1-6 This utility model discloses a vertical rotary tempering furnace, which is mainly used for the physical tempering of glass. It can effectively reduce the number of furnace openings, reduce heat loss, and improve energy utilization. The technical solution disclosed in this utility model will be described below by way of specific embodiments.

[0040] In one specific embodiment disclosed in this utility model, such as Figure 1 The main structure of the vertical rotary tempering furnace includes a furnace body 1, a rotary working tube 3, and a heat-conducting base 5. Air-cooled fans 2 are symmetrically arranged on both sides of the furnace body 1. These fans are driven by electricity supplied by thermoelectric batteries 6 and blow air into the furnace body 1, which then enters the rotary working tube 3. A lifting cover 4 is installed at the top of the rotary working tube 3, and a stacking frame 7 is installed in the center of the cover 4. The rotary working tube 3 is driven to rotate by a servo motor 8. The furnace body 1 generates heat, which is transferred to the glass inside the rotary working tube 3. When the glass temperature reaches near its softening temperature, the rotary working tube 3 rotates 90 degrees, transferring the heat through the heat-conducting base 5 to the thermoelectric batteries 6, creating a thermoelectric potential difference. This generates current that drives the air-cooled fans 2 to blow air from both sides of the furnace body 1 into the rotary working tube 3, thus forming heat dissipation convection to cool the glass.

[0041] In this embodiment, as Figure 4Thermoelectric batteries 6 are installed at both ends of the heat-conducting base 5, and the thermoelectric batteries 6 are connected to the air-cooled fan 2. A servo motor 8 is installed in the middle of the heat-conducting base 5, and the servo motor 8 is suitable for driving the rotary working tube 3 to rotate. Based on this structure, a temperature sensor is installed inside the lifting cover 4. The temperature sensor is connected to the microcontroller circuit, and the microcontroller is connected to the buzzer circuit. When the temperature sensor detects that the temperature of the furnace body 1 is higher than 700 degrees Celsius, the microcontroller drives the servo motor 8 to rotate 90 degrees. When the temperature of the furnace body 1 is lower than 50 degrees Celsius, the buzzer sounds an alarm to remind the worker to remove the product.

[0042] In this embodiment, the rotary working tube 3 includes an insulated tube body 31 and a heat-conducting groove 32. The insulated tube body 31 is made of heat-insulating material, and a retaining ring 35 is provided at its top end. The retaining ring 35 can be slidably set at the top of the furnace body 1 to prevent the insulated tube body 31 from falling. A gear ring 33 is coaxially provided at the bottom of the insulated tube body 31. The gear ring 33 is meshed with the drive gear 53 for transmission, and the drive gear 53 is coaxially connected with the servo motor 8, thereby improving the output power and reducing the size of the servo motor 8.

[0043] In this embodiment, two heat-conducting grooves 32 are symmetrically arranged on the side of the heat insulation tube 31, and a heat dissipation port 34 is provided at the bottom of the heat insulation tube 31 to effectively utilize heat.

[0044] Specifically, in some embodiments, the thermal base 5 includes a base 51, a drive gear 53, and a battery compartment 55. When cooling of the glass is required, the servo motor 8 drives the heat insulation tube 31 to rotate 90 degrees, so that the heat conduction groove 32 faces the air-cooling fan 2. At the same time, the heat dissipation port 34 and the heat conduction channel 52 are connected. Since the battery compartment 55 contains a thermoelectric battery 6, and the bottom of the battery compartment 55 is connected to the heat inlet 56 through the heat conduction channel 52, and the heat inlet 56 is set on the sealing plate 54 and adapted to be connected to the heat dissipation port 34, the thermoelectric battery 6 can sense the heat from the glass, thereby generating a voltage difference in the thermoelectric battery 6, which in turn drives the air-cooling fan 2 to run. Furthermore, as heat dissipation progresses, the voltage difference generated by the thermoelectric battery 6 will further increase, thereby causing the air-cooling fan 2 to run at full power and accelerate the cooling speed of the glass.

[0045] In this embodiment, a sealing disk 54 is provided in the middle of the base 1. The sealing disk 54 is located inside the gear ring 33, and the drive gear 5 is located inside the sealing disk 54 and meshes with the gear ring 33 for transmission. The drive gear 53 is coaxially connected to the servo motor 8 for transmission.

[0046] In this embodiment, as Figure 3The air-cooled fan 2 includes a housing 21, an industrial fan 22, and a dust filter 23. A pair of housings 21 are installed on both sides of the furnace body 1. Multiple industrial fans 22 are installed on the back side of each housing 21, and a dust filter 23 is installed on the front side to prevent dust from entering and falling on the tempered glass.

[0047] In a specific embodiment of this utility model, the stacking frame 7 includes a slot 71, a frame body 72, and a fixing screw hole 73. The lifting cover 4 is fixedly connected to the end of the frame body 72. Multiple slots 71 are vertically arranged inside the frame body 72. The fixing screw hole 73 is provided outside the slot 71. The fixing screw hole 73 is suitable for installing fasteners and fixing the glass in the slot 71 by fasteners.

[0048] In this embodiment, the furnace body 1 includes a heating plate 11 and a furnace chamber 13. The inner side of the heating plate 1 is provided with several electric heating units 12, and the outer side is coated with a heat insulation layer to reduce heat loss. The front and rear sides of the furnace chamber 13 are provided with heating plates 11, and the left and right sides of the furnace chamber 13 are provided with air inlets 14. A rotating inner cavity 15 is provided at the center of the furnace chamber 13. The rotating inner cavity 15 is connected to the heating plate 11 and the air inlets 14. The air inlets 14 are funnel-shaped, which can effectively increase the air velocity and thus improve the cooling speed.

[0049] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
