Technical Field

[0001] The utility model relates to the technical field of glass processing, in particular to a glass tempering furnace. Background Art

[0002] A glass tempering furnace is a device used to enhance the physical properties of glass. It heats and rapidly cools the glass. The main function of the glass tempering furnace is to transform ordinary glass into tempered glass, enhancing its physical properties to meet the requirements of specific applications, making it have higher strength and hardness.

[0003] When the glass enters the interior of the glass tempering furnace, the lower surface of the glass is heated by ceramic roller rods on the lower surface, and the upper surface of the glass is heated by hot air flow after the air flow passes through heating wires by a heating fan. Since the distances of different positions of the glass from the outlet of the heating hot air flow are different, there are differences in the heating effects, resulting in problems such as warping and deformation of the processed glass. Therefore, we propose a glass tempering furnace to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems of warping and deformation caused by uneven heating of different regions on the glass in the prior art, and to propose a glass tempering furnace.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A glass tempering furnace includes a lower furnace body, a ceramic heating roller is installed on the lower furnace body, an upper furnace body is installed on the lower furnace body, a furnace chamber is opened on the upper furnace body, a heating component is installed in the furnace chamber, a fan is installed on the upper furnace body, and a plurality of mounting holes are provided on the lower end surface of the upper furnace body, and a ventilation pipe is installed on the mounting holes.

[0007] A further scheme of the utility model is that the heating component is an electric heating wire installed in the furnace chamber. The electric heating wire is tubular and is connected and located in the same plane, and the temperature of each part of the electric heating wire is the same. The fan is installed at the upper end of the upper furnace body, and the fan is communicated with the furnace chamber.

[0008] A further scheme of the utility model is that ventilation holes are provided on the lower side of the ventilation pipe, the ventilation holes communicate the furnace chamber with the ventilation pipe, and a mucosa is provided on the bottom surface of the furnace chamber.

[0009] A further scheme of the utility model is that an annular connecting wall is provided in the ventilation pipe, and air outlet holes are provided at the lower end of the ventilation pipe.

[0010] A further scheme of the utility model is that a lifting hydraulic cylinder is provided on the lower furnace body, and the other end of the lifting hydraulic cylinder is connected to the upper furnace body.

[0011] A further solution of the present utility model is that the mounting holes are evenly arranged on the lower end surface of the upper furnace body.

[0012] Compared with the prior art, the present utility model provides a glass tempering furnace, which has the following beneficial effects.

[0013] 1. In the present utility model, after the gas in the furnace chamber is heated to a certain temperature under the action of the heating wire, the flow direction of the gas is changed, avoiding the direct flow of the gas in the furnace chamber to the upper surface of the glass tempering plate after uneven heating, resulting in uneven heating of some areas on the upper surface of the glass tempering plate, causing warping and deformation of the glass tempering plate, improving the quality qualification rate of the glass tempering plate, and ensuring the product quality.

[0014] 2. In the present utility model, through the mucosa, the gas introduced by the fan is directly blown onto the mucosa on the bottom surface of the furnace chamber after being heated in the furnace chamber, and the impurity particles in the air are further adhered and absorbed. The heated air flow forms a gas passage through the annular connecting wall inside the ventilation pipe and escapes upward, and then escapes downward in the pipeline formed by the annular connecting wall, and flows through the air outlet holes to the upper surface of the glass tempering plate, uniformly heating the upper surface of the glass tempering plate, so that the heating effects of all parts of the glass tempering plate are consistent.

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Refer to Figures 1-6 , a glass tempering furnace of the present invention includes a lower furnace body 1, a ceramic heating roller 2 is installed on the lower furnace body 1, and the ceramic heating roller 2 is used to heat the lower surface of the glass tempering plate. An upper furnace body 3 is installed on the lower furnace body 1. A furnace chamber 31 is opened on the upper furnace body 3. A heating component is installed in the furnace chamber 31 to heat the air flow in the furnace chamber 31. A fan 4 is installed on the upper furnace body 3. A plurality of mounting holes 32 are provided on the lower end surface of the upper furnace body 3. The mounting holes 32 are evenly arranged on the lower end surface of the upper furnace body 3. A vent pipe 5 is installed on the mounting holes 32. An air flow channel is provided inside the vent pipe 5. After the gas in the furnace chamber 31 is heated to a certain temperature by the heating component, the flow direction of the air flow is changed, so as to avoid the gas in the furnace chamber 31 flowing directly to the upper surface of the glass tempering plate after uneven heating, resulting in uneven heating of some areas on the upper surface of the glass tempering plate, causing the glass tempering plate to warp and deform, improving the quality qualification rate of the glass tempering plate, and ensuring the product quality.

[0026] The heating component is an electric heating wire 6 installed in the furnace chamber 31. The electric heating wire 6 is tubular and communicates in the same plane, and the temperature of each part of the electric heating wire 6 is the same, ensuring that the air flow is evenly heated when passing through the plane formed by the electric heating wire 6, so as to ensure that the temperatures of all parts of the air flow in the furnace chamber 31 are uniform. The fan 4 is installed at the upper end of the upper furnace body 3. The fan 4 communicates with the furnace chamber 31. A filtering component is provided at the air inlet port of the fan 4 to filter impurities in the air, avoiding the impurities being blown onto the upper surface of the glass tempering plate, ensuring that there will be no dust on the surface of the glass tempering plate during the glass tempering process, resulting in scratches, spots or other defects on the surface of the glass tempering plate, and ensuring the surface quality of the glass tempering plate during the tempering process.

[0027] An air vent hole 51 is provided on the lower side of the vent pipe 5. The air vent hole 51 connects the furnace cavity 31 with the vent pipe 5. A mucosa 311 is provided on the inner bottom surface of the furnace cavity 31, so that the gas introduced by the blower 4 is directly blown onto the mucosa 311 on the inner bottom surface of the furnace cavity 31 after being heated in the furnace cavity 31. The impurity particles in the air are further adhered and absorbed. At this time, the air flow passes through the contact area of the bottom surface of the furnace cavity 31, and the gas velocity suddenly drops or the air flow reversely circulates, and further contacts the heating wire 6 for heating, ensuring that the gas temperature in the furnace cavity 31 is uniform. A circular connecting wall 52 is provided in the vent pipe 5, and an air outlet hole 53 is provided at the lower end of the vent pipe 5. The heated air flow escapes upward through the gas passage formed by the circular connecting wall 52 inside the vent pipe 5, and then escapes downward in the pipeline formed by the circular connecting wall 52, and flows through the air outlet hole 53 to the upper surface of the glass toughening plate, uniformly heating the upper surface of the glass toughening plate, so that the heating effects of each part area of the glass toughening plate are consistent.

[0028] A lifting hydraulic cylinder 11 is provided on the lower furnace body 1. The other end of the lifting hydraulic cylinder 11 is connected to the upper furnace body 3. The lifting hydraulic cylinder 11 is used to lift the upper furnace body 3, facilitating the installation and disassembly of the ceramic heating roller 2 on the lower furnace body 1. Feed ports and discharge ports are respectively provided on the left and right sides of the lower furnace body 1. The glass toughening plate enters from the feed port on the left side of the lower furnace body 1 and slowly moves to the right under the action of the ceramic heating roller 2, and is heated and toughened by the ceramic heating roller 2 and the heating air flow in the upper furnace body 3 during this process. The ceramic heating roller 2 is driven to rotate through the chain and motor provided on the lower furnace body 1.

[0029] In the present utility model, the glass toughening plate enters from the feed port on the left side of the lower furnace body 1 and slowly moves to the right under the action of the ceramic heating roller 2. The ceramic heating roller 2 heats the lower surface of the glass toughening plate. The gas introduced by the blower 4 is directly blown onto the mucosa 311 on the inner bottom surface of the furnace cavity 31 after being heated in the furnace cavity 31. The impurity particles in the air are further adhered and absorbed. At this time, the air flow passes through the contact area of the bottom surface of the furnace cavity 31, and the gas velocity suddenly drops or the air flow reversely circulates, and further contacts the heating wire 6 for heating, and flows through the air outlet hole 53 to the upper surface of the glass toughening plate, uniformly heating the upper surface of the glass toughening plate, so that the heating effects of each part area of the glass toughening plate are consistent.
