Description

Technical Field

[0001] This utility model relates to the field of borosilicate glass technology, specifically to an overflow device for a borosilicate glass kiln. Background Technology

[0002] In the production process of borosilicate glass, the melting and clarification of borosilicate glass is difficult, and the production conditions are quite harsh, requiring high temperatures. However, at high temperatures, the B2O3 in the molten glass is easily volatilized, and a layer of glass rich in SiO2 will accumulate on the surface of the molten glass, commonly known as "skin". The density of glassy SiO2 is less than that of molten glass, so it will float on the surface of the molten glass. After a long period of retention, a milky white opaque substance with SiO2 crystals will be formed, which is technically called scum. Once this scum enters the molten glass production flow, it will cause opaque defects or even streaks on the glass surface, affecting the quality.

[0003] Traditional kiln overflow equipment typically has a fixed flow channel structure. These channels are made of refractory material and are used to guide the molten glass from the kiln to the overflow port. The overflow port is of a fixed size and is usually located at the bottom or side of the kiln to ensure that the molten glass can flow out smoothly and continuously.

[0004] Because the overflow port is fixed, the opening size cannot be adjusted, making it impossible to accurately control the flow rate. This can easily cause stagnation during borosilicate glass production, affecting product quality. It is necessary to replace the overflow port with one of the appropriate size in advance, which is cumbersome and affects production efficiency. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an overflow device for a borosilicate glass furnace. By driving a lead screw to rotate via a motor, the adjusting plates on both sides can be moved closer or further apart in the horizontal direction, allowing control of the overflow port's opening size and achieving precise control of the overflow flow rate. The heating mechanism ensures that the molten glass remains in a flowing state as it flows out of the overflow port, improving the quality and production efficiency of borosilicate glass products.

[0006] To achieve the above objectives, according to an embodiment of the first aspect of this utility model, an overflow device for a borosilicate glass furnace is provided, comprising an overflow seat, a heating mechanism, and an adjusting mechanism. The overflow seat has an overflow port, and the heating mechanism is located below the overflow seat to heat the borosilicate glass liquid within the overflow port. The adjusting mechanism includes a guide plate, an adjusting seat, and an adjusting plate. The guide plate is located on the side wall of the overflow seat, and the adjusting seat is fixedly located below the guide plate. A lead screw is provided inside the adjusting seat, and a partition ring is located at the middle position of the lead screw. The threads on both sides of the partition ring have opposite directions. A motor is located on the side wall of the adjusting seat, and the output end of the motor is connected to the lead screw. Slider blocks are respectively provided on the lead screws on both sides of the partition ring, and guide rods are provided at the top of the sliders. A guide groove is provided on the guide plate, and the guide rod slides into the guide groove. A connecting rod is provided at one end of the guide rod extending out of the guide groove, and the connecting rod is connected to the adjusting plate. A sealing plate is provided on the side wall of the adjusting plate, and the sealing plate slides into the side wall of the overflow seat.

[0007] As a further embodiment of this utility model: the heating mechanism includes a heat insulation box, a burner and a combustion nozzle. The heat insulation box is located at the bottom of the overflow seat, the burner is located at the bottom of the heat insulation box, and its output end is inserted into the heat insulation box and connected to the combustion nozzle. The bottom of the overflow seat is made of a heat-conducting material.

[0008] As a further embodiment of this utility model: a fire guide plate is provided at the bottom of the overflow seat, the fire guide plate is in the shape of an inverted triangle, and the combustion nozzle is located below the fire guide plate.

[0009] As a further embodiment of this utility model: the bottom of the overflow port is inclined and connected to the guide plate.

[0010] As a further embodiment of this utility model: the connection between the adjusting plate and the sealing plate has a rounded corner on the side facing the overflow port.

[0011] As a further embodiment of this utility model, the adjusting plate and the sealing plate are made of high-temperature resistant materials.

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

[0013] 1. This utility model uses a motor to drive a lead screw to rotate. Since the threads on both sides of the partition ring are in opposite directions, the sliders on both sides of the partition ring will move closer to each other. As the sliders move, the guide rod drives the connecting rod to drive the adjusting plate to move horizontally, thereby controlling the size of the overflow port and controlling the overflow flow. At the same time, the sealing plate on the side wall of the adjusting plate slides in cooperation with the side wall of the overflow seat to ensure that there is no leakage of molten glass during the adjustment process. The heating mechanism keeps the molten glass flowing out of the overflow port, improving the quality and production efficiency of borosilicate glass products.

[0014] 2. This utility model improves the fluidity of borosilicate glass liquid by setting a burner and a combustion nozzle to heat the bottom of the overflow seat, thereby preventing solidification of the borosilicate glass liquid, improving the outflow efficiency, and avoiding damage to the product. At the same time, the heat insulation box reduces heat loss, allowing the heat generated by the burner to be transferred to the borosilicate glass liquid more efficiently.

[0015] 3. This utility model uses a fire guide plate arranged in an inverted triangular shape at the bottom of the overflow seat, which allows the flame to spread along the inclined surface of the fire guide plate, thereby increasing the contact area between the flame and the bottom of the overflow seat and improving the heating efficiency.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. 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.

[0022] like Figures 1 to 4 As shown, an overflow device for a borosilicate glass furnace includes an overflow seat 1, a heating mechanism and an adjusting mechanism. The overflow seat 1 has an overflow port 11, and the heating mechanism is located below the overflow seat 1 to heat the borosilicate glass liquid in the overflow port 11.

[0023] The adjustment mechanism includes a guide plate 2, an adjustment seat 3, and an adjustment plate 4. The guide plate 2 is disposed on the side wall of the overflow seat 1. The adjustment seat 3 is fixedly disposed below the guide plate 2. A lead screw 31 is disposed inside the adjustment seat 3. A partition ring 32 is disposed in the middle of the lead screw 31. The threads on both sides of the partition ring 32 are in opposite directions. A motor 33 is disposed on the side wall of the adjustment seat 3. The output end of the motor 33 is connected to the lead screw 31. Slider blocks 34 are respectively disposed on the lead screw 31 on both sides of the partition ring 32. A guide rod 35 is disposed on the top of the slider 34. A guide groove 21 is opened on the guide plate 2. The guide rod 35 is slidably engaged with the guide groove 21. A connecting rod 36 is disposed at the end of the guide rod 35 extending out of the guide groove 21. The connecting rod 36 is connected to the adjustment plate 4. A sealing plate 41 is disposed on the side wall of the adjustment plate 4. The sealing plate 41 is slidably engaged with the side wall of the overflow seat 1, and the adjustment plate 4 is slidably engaged with the guide plate 2.

[0024] When it is necessary to adjust the overflow rate of borosilicate glass liquid, the motor 33 drives the lead screw 31 to rotate. Since the threads on both sides of the partition ring 32 are in opposite directions, the sliders 34 on both sides of the partition ring 32 will move closer to each other. As the sliders 34 move, the guide rod 35 drives the connecting rod 36 to drive the adjusting plate 4 to move horizontally, thereby controlling the opening size of the overflow port 11 and realizing the control of the overflow rate. At the same time, the sealing plate 41 on the side wall of the adjusting plate 4 slides and engages with the side wall of the overflow seat 1 to ensure that there is no leakage of glass liquid during the adjustment process. The heating mechanism keeps the glass liquid flowing out of the overflow port 11, improving the quality and production efficiency of borosilicate glass products.

[0025] The heating mechanism includes a heat insulation box 5, a burner 51 and a combustion nozzle 52. The heat insulation box 5 is located at the bottom of the overflow seat 1. The burner 51 is located at the bottom of the heat insulation box 5, and its output end is inserted into the heat insulation box 5 and connected to the combustion nozzle 52. The bottom of the overflow seat 1 is made of heat-conducting material.

[0026] By setting burner 51 and combustion nozzle 52 to heat the bottom of overflow seat 1, the fluidity of borosilicate glass liquid is improved, solidification of borosilicate glass liquid is avoided, the outflow efficiency is improved, and damage to the product is avoided. At the same time, heat insulation box 5 reduces heat loss, so that the heat generated by burner 51 can be transferred to borosilicate glass liquid more efficiently.

[0027] The bottom of the overflow seat 1 is provided with a fire guide plate 6, which is in the shape of an inverted triangle, and the combustion nozzle 52 is located below the fire guide plate 6.

[0028] The inverted triangular shape of the guide plate 6 at the bottom of the overflow seat 1 allows the flame to spread along the slope of the guide plate 6, thereby increasing the contact area between the flame and the bottom of the overflow seat 1 and improving the heating efficiency.

[0029] The overflow port 11 is inclined at the bottom and connected to the guide plate 2.

[0030] By tilting the bottom of the overflow port 11, the fluidity of the molten glass is improved, the residence time of the molten glass in the overflow seat 1 is reduced, and the overflow efficiency is improved.

[0031] The connection between the adjusting plate 4 and the sealing plate 41 is provided with a rounded corner 42 on the side facing the overflow port 11 to ensure that the molten glass can flow out smoothly and avoid forming dead corners or accumulating in the overflow port 11.

[0032] The regulating plate 4 and the sealing plate 41 are made of high-temperature resistant materials.

[0033] The working principle of this invention is as follows: The motor 33 drives the lead screw 31 to rotate. Utilizing the opposite direction of the threads on both sides of the partition ring 32, the slider 34 moves closer together, causing the adjusting plate 4 to move horizontally, thereby controlling the opening size of the overflow port 11 and achieving precise adjustment of the overflow flow. Simultaneously, the burner 51 and combustion nozzle 52 in the heating mechanism efficiently heat the bottom of the overflow seat 1, improving the fluidity of the molten glass. The inverted triangular design of the guide plate 6 increases the flame contact area and improves heating efficiency. The inclined bottom of the overflow port 11 and the rounded corner 42 between the adjusting plate 4 and the sealing plate 41 ensure smooth flow of the molten glass and prevent accumulation. The entire device is made of high-temperature resistant materials to ensure efficient and stable operation.

[0034] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
