Description

Technical Field

[0001] This utility model relates to the field of glass furnace equipment, and in particular to a heat-circulating energy-saving glass furnace. Background Technology

[0002] A glass furnace is a thermal equipment used in glass manufacturing to melt glass batches. The batches used to produce glass are melted and clarified at high temperatures in the furnace to form molten glass that meets the forming requirements. The glass furnace is mainly responsible for providing molten glass with good melting quality, stable temperature, and uniform composition for subsequent processes.

[0003] Currently, traditional glass furnaces have simple feeding platforms with mostly planar structures. Feeding is done manually by shoveling or by pushing with a linkage. There is a lack of effective feeding assistance and raw material pretreatment measures. During the feeding process, the raw materials cannot be preheated, which is not conducive to the subsequent melting process of the glass raw materials and further increases energy consumption.

[0004] Therefore, it is necessary to propose a heat-circulating energy-saving glass furnace to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a thermal circulation energy-saving glass furnace to solve the problem mentioned in the background art, where the glass melt in the mold relies solely on natural flow distribution and lacks active and effective control methods, resulting in a high defect rate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat-circulating energy-saving glass furnace, comprising a furnace body, wherein burners are symmetrically arranged on both sides of the furnace body, and multiple burners are arranged and evenly distributed on both sides of the furnace body at equal intervals;

[0007] A blower is installed on the upper surface of the kiln body near the front. A base is installed on the front surface of the kiln body. A feeding platform is fixedly installed on the upper surface of the base. A top cover is installed above the feeding platform. An air guide pipe is installed at the output end of the blower and is connected to the top cover.

[0008] Preferably, the feeding platform has a U-shaped design, with an arc baffle fixedly installed on the upper surface of the feeding platform, and a feeding plate installed below the arc baffle and at a position on the feeding platform.

[0009] Preferably, the feed plate is designed in an "L" shape, and the upper half of the feed plate has holes. Multiple holes are arranged in an array on the upper half of the feed plate, and the connection of the feed plate forms an arc-shaped surface.

[0010] Preferably, a through hole is provided on the upper surface of the cover near the front, the air guide pipe passes through the through hole and is connected to the cover, and a rotating shaft is rotatably installed in front of the through hole and inside the cover, and an air guide plate is fixedly installed on the rotating shaft.

[0011] Preferably, a spring is installed at one end of the rotating shaft, and a limit post is installed at the other end of the rotating shaft.

[0012] Preferably, the limiting post is U-shaped, with one end fixedly connected to the rotating shaft and the other end locked in the limiting hole, and two limiting holes are provided.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. The feeding platform and feeding plate set in this utility model use circulating hot air to preheat the raw materials on the feeding platform, and at the same time assist feeding. During the feeding process, the raw materials are screened to ensure uniformity in size, thereby improving the uniformity and transparency of the glass, improving the product quality of the molten glass, and the preheated raw materials can reach the melting temperature more quickly after entering the furnace, shortening the melting time, which is beneficial to the subsequent melting process of the glass raw materials, significantly improving energy utilization efficiency and reducing energy consumption.

[0015] 2. The rotating shaft and limiting post set in this utility model can easily change the angle of the air guide plate by simply pulling the rotating shaft outward and pulling the limiting post out of one limiting hole and inserting it into another limiting hole. Combined with the adjustment of the air volume of the fan, the switching between preheating and feeding modes can be easily completed. This operation method is simple and easy to understand, reducing the difficulty of operation for workers. Attached Figure Description

[0022] This utility model provides a heat-circulating energy-saving glass furnace. Please refer to the appendix. Figure 1 As shown.

[0023] The furnace includes a main body 1, and burners 2 are symmetrically arranged on both sides of the main body 1. There are multiple burners 2, which are evenly distributed on both sides of the main body 1. The symmetrical and evenly distributed burners 2 can make the furnace interior heat evenly, ensuring that the glass raw materials melt more fully and evenly, which is conducive to improving the stability of the glass melt quality.

[0024] Furthermore, a blower 3 is installed on the upper surface of the kiln body 1 near the front. The blower 3 is connected to the interior of the kiln body 1. A base 8 is installed on the front surface of the kiln body 1. A feeding platform 7 is fixedly installed on the upper surface of the base 8. A top cover 6 is installed above the feeding platform 7. An air guide pipe 4 is installed at the output end of the blower 3. The air guide pipe 4 is connected to the top cover 6. The blower 3 delivers hot air to the feeding platform 7 through the air guide pipe 4 to achieve hot air circulation, which can realize feeding and preheat the raw materials on the feeding platform 7 at the same time.

[0025] Please see the appendix Figure 2 -Appendix Figure 3 As shown.

[0026] The feeding platform 7 has a U-shaped design. An arc baffle 5 is fixedly installed on the upper surface of the feeding platform 7, and a feeding plate 9 is installed below the arc baffle 5 and on the feeding platform 7.

[0027] Furthermore, a through hole is provided on the upper surface of the cover 6 near the front, and the air guide pipe 4 passes through the through hole and is connected to the cover 6 to ensure that the hot air delivered by the fan 3 can smoothly enter the feeding platform 7, providing a passage for feeding and preheating raw materials.

[0028] Please see the appendix Figure 4 As shown.

[0029] The feed plate 9 has an "L" shape design. The upper half of the feed plate 9 has holes 10. The "L" shape design combined with the holes 10 can screen the raw materials to ensure the uniformity of the diameter of the raw materials and avoid the occurrence of raw materials of different sizes. Uneven raw material sizes are prone to forming unmelted particles in the glass melt, which will affect the uniformity and transparency of the glass and reduce the quality of the glass melt.

[0030] Specifically, multiple holes 10 are provided and arrayed on the upper half of the feed plate 9. By blowing the blower 3, raw materials with uniform diameter are screened out, while raw materials with excessive diameter will slide down the lower half of the feed plate 9 back onto the feed platform 7.

[0031] Specifically, the connection of the feed plate 9 has an arc-shaped surface 11, which facilitates the smooth flow of glass raw materials, reduces jamming and residue at the connection, and ensures the continuity of the feeding process.

[0032] Please see the appendix Figure 5 As shown.

[0033] A rotating shaft 12 is rotatably mounted in front of the through hole and inside the upper cover 6.

[0034] Specifically, a guide plate 14 is fixedly installed on the rotating shaft 12. The rotating shaft 12 provides support for the rotation of the guide plate 14, so that the guide plate 14 can change its angle, thereby adjusting the direction of the gas conveyed by the fan 3. In conjunction with the wind force adjustment of the fan 3, the mode switching of preheating and feeding can be realized.

[0035] Specifically, a spring 13 is installed at one end of the rotating shaft 12, and a limit post 15 is installed at the other end of the rotating shaft 12. The spring 13 serves to reset and limit the position.

[0036] Specifically, the limiting post 15 has a "U" shaped design. One end of the limiting post 15 is fixedly connected to the rotating shaft 12, and the other end is locked in the limiting hole 16. When the angle needs to be adjusted, the rotating shaft 12 is pulled outward to pull the limiting post 15 out of the limiting hole 16, and then it is inserted into another limiting hole 16. Under the action of the spring 13, it is reset and limited, thus achieving the purpose of angle adjustment.

[0037] Specifically, two limiting holes 16 are provided. The first limiting hole 16 is parallel to the rotating shaft 12, and the second limiting hole 16 is located at a 45-degree angle above the rotating shaft 12. When the limiting post 15 is located in the first limiting hole 16, the air guide plate 14 is in a vertical state. When the limiting post 15 is located in the second limiting hole 16, the air guide plate 14 is tilted at a 45-degree angle towards the kiln body 1. When the air guide plate 14 is in a vertical state, the air volume of the fan 3 is reduced to preheat the raw materials. When the air guide plate 14 is in a tilted state, the air volume of the fan 3 is increased to feed the raw materials. At the same time, in conjunction with the feeding plate 9, the diameter of the raw materials is screened to improve the production quality of the glass melt.

[0038] When in use, start the blower 3. The blower 3 delivers hot air into the upper cover 6 through the air guide pipe 4. The hot air enters the feeding platform 7. At this time, reduce the air volume of the blower 3. The vertical air guide plate 14 guides the hot air to be evenly distributed on the feeding platform 7 to preheat the raw materials, which helps the subsequent melting process and improves energy utilization efficiency. The "U"-shaped design of the feeding platform 7 can collect hot air and avoid heat loss. At the same time, it is conducive to the stacking of raw materials. The arc baffle 5 prevents the raw materials from scattering due to the impact of hot air.

[0039] Once the raw materials are preheated to a certain degree, a feeding operation is required. Pull the rotating shaft 12 outward to remove the limiting post 15 from the first limiting hole 16. Rotate the rotating shaft 12 to make the limiting post 15 engage in the second limiting hole 16. At this time, the air guide plate 14 is tilted 45 degrees towards the kiln body 1, and the air volume of the blower 3 is increased. The strong wind blows through the air guide pipe 4 and the tilted air guide plate 14 towards the feeding platform 7. The raw materials move under the action of the wind. The multiple arrays of holes 10 on the upper half of the "L"-shaped feeding plate 9 begin to play a screening role. Raw materials with the required diameter pass through the holes 10 and fall into the kiln body 1 along the feeding plate 9. Raw materials with an excessively large diameter slide back to the feeding platform 7 along the lower half of the feeding plate 9. The arc-shaped surface 11 at the connection of the feeding plate 9 ensures that the raw materials slide smoothly, reducing jamming and residue, and ensuring the continuity of the feeding process.
