Description

Technical Field

[0001] This utility model relates to the technical field of glass production and processing, specifically to a continuous powder feeding device for a flat glass kiln. Background Technology

[0002] A glass furnace is a large-scale thermal equipment used for melting and refining glass raw materials. Its main function is to heat various glass raw materials (such as quartz sand, soda ash, limestone, etc.) to high temperatures to melt them, and then, through processes such as clarification and homogenization, make the molten glass reach the required quality and properties, and finally shape the molten glass into various glass products.

[0003] In the production of flat glass, a continuous feeding device is needed to place glass powder raw materials into the glass furnace. Due to the properties of the powder itself, a spiral conveyor is generally used for its transport. However, this device has certain drawbacks. First, because glass powder still contains large quartz particles, the spiral blades of the bolt conveyor are easily jammed by the quartz sand in the powder, affecting normal operation. Second, the outlet of the spiral conveyor is often small, while the entire furnace area is large. When the powder is transported to the furnace, it becomes too concentrated, thus affecting the melting efficiency. Furthermore, the outlet height of existing spiral conveyors generally does not have an adjustable function, making it unable to better adapt to glass furnaces of different heights.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a continuous powder feeding device for flat glass furnaces. By designing a discharge component, this invention solves the problem that in related solutions, the discharge port of the discharge component is generally small, making it impossible to evenly disperse the glass powder into the entire glass furnace, resulting in low melting efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A continuous powder feeding device for a flat glass furnace includes a main component, the main component including a conveying cylinder, a spiral blade is provided in the inner cavity of the conveying cylinder, a side blade is fixed on the outer periphery of the spiral blade, a conveying motor is fixed at one end of the conveying cylinder, the power shaft of the conveying motor passes through the conveying cylinder and is fixedly connected to the central shaft of the spiral blade, and a feed hopper is fixedly provided through the outer periphery of the conveying cylinder.

[0008] A discharge assembly is also provided on the outer periphery of the conveying cylinder. The discharge assembly includes a connector that is fixedly connected to the conveying cylinder. A movable part is movably connected to the peripheral wall of the connector. An umbrella-shaped material outlet is fixedly connected to the end of the movable part away from the connector. A material distribution chamber is opened on the inner side of the umbrella-shaped material outlet.

[0009] Preferably, the main component further includes a support member and an adjusting member disposed on the outer periphery of the conveying cylinder. The adjusting member includes a sliding member disposed on the outer periphery of the conveying cylinder. A sliding outer cylinder is also slidably connected to the outer periphery of the sliding member. The adjusting member also includes a base plate. A telescopic support rod and a hydraulic telescopic rod are fixed on the base plate. The telescopic end of the hydraulic telescopic rod is fixedly connected to the telescopic support rod telescopic component.

[0010] Preferably, the material distribution chamber is configured as a plurality of chambers.

[0011] Preferably, multiple connecting rods are fixed inside the umbrella-shaped feed opening.

[0012] Preferably, the connecting rod has an elliptical cross-section.

[0013] Preferably, an adjusting motor is also fixed to one end of the connector, and the power shaft of the adjusting motor passes through the connector and is fixedly connected to the movable part.

[0014] Compared with the prior art, this utility model provides a continuous powder feeding device for a flat glass furnace, which has the following beneficial effects:

[0015] 1. This utility model, through its main component, allows for adjustment of the discharge component height via an adjusting mechanism. First, the hydraulic telescopic rod moves upward, causing the sliding outer cylinder to move upward while the support component remains fixed in position. Ultimately, this causes the discharge component to move upward and be adjusted to a suitable height. One end of the connecting component is also fixed with an adjusting motor. The motor's power shaft passes through the connecting component and is fixedly connected to the movable component. When the adjusting mechanism lifts the discharge component, the adjusting motor rotates accordingly, ensuring that the umbrella-shaped material outlet is always vertically downward. This solves the problem in related solutions where the discharge outlet of the transmission device cannot be adjusted according to the height of the glass kiln, thus preventing it from being at the optimal material dropping height.

[0016] 2. This utility model, through its main component, activates a transmission motor during material feeding, driving the spiral blades to rotate, thereby initiating the transmission of glass powder. The outer periphery of the spiral blades of this device is provided with side blades, and the angle between the side blades and the transmission cylinder is large, making it less likely for large quartz particles in the powder to get stuck in the gap between the spiral blades and the transmission cylinder. This greatly improves the problem in existing solutions where spiral blade transmission is easily blocked by large quartz sand particles in the glass powder that are not completely destroyed, thus affecting the transmission.

[0017] 3. In this invention, the glass powder, driven by the spiral blades, reaches the discharge port through the discharge component. After passing through the connecting and moving parts, it finally flows out from the umbrella-shaped discharge port. The umbrella-shaped discharge port of this device is provided with multiple discharge chambers, with a narrow inlet and a large discharge port coverage area. This allows the powder to be evenly dispersed and placed more widely into the entire glass furnace, facilitating its melting. This solves the problem in related solutions where the discharge port of the discharge component is generally small, making it impossible to evenly disperse the glass powder into the entire glass furnace, resulting in low melting efficiency.

[0026] 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.

[0027] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a continuous powder feeding device for flat glass furnace.

[0028] Please see Figure 1 - Figure 5 A continuous powder feeding device for a flat glass furnace includes a main component 1, which includes a conveying cylinder 11. The inner cavity of the conveying cylinder 11 is provided with a spiral blade 12, and a side blade 13 is fixed on the outer periphery of the spiral blade 12. A conveying motor 14 is fixed at one end of the conveying cylinder 11. The power shaft of the conveying motor 14 passes through the conveying cylinder 11 and is fixedly connected to the central shaft of the spiral blade 12. A feed hopper 15 is fixedly connected through the outer periphery of the conveying cylinder 11.

[0029] The outer periphery of the conveying cylinder 11 is also provided with a discharge component 2. The discharge component 2 includes a connector 21 that is fixed through the conveying cylinder 11. A movable component 22 is movably and through the peripheral wall of the connector 21. An umbrella-shaped material outlet 23 is fixed through the end of the movable component 22 away from the connector 21. A material distribution chamber 231 is opened on the inner side of the umbrella-shaped material outlet 23.

[0030] When using this device, place it next to the glass furnace, and then adjust the height of the discharge assembly 2 using the adjusting component 17. First, the hydraulic telescopic rod 175 moves upward, causing the sliding outer cylinder 172 to move upward, while the support component 16 remains fixed in position, thereby tilting the entire conveying cylinder 11 and ultimately causing the discharge assembly 2 to move upward. Once the discharge assembly 2 reaches a certain height, push the entire device above the glass furnace so that the umbrella-shaped material inlet 23 is positioned directly above the furnace. Then, begin adding glass powder into the feed hopper 15, start the conveying motor 14, and drive the screw blades to rotate, thus beginning the conveying of glass. The device has side blades 13 on the outer periphery of the spiral blades. The side blades 13 and the conveyor cylinder 11 form a large inclination angle, which makes it difficult for large quartz particles in the powder to get stuck in the gap between the spiral blades 12 and the conveyor cylinder 11. Driven by the spiral blades 12, the powder reaches the discharge assembly 2, and flows out from the umbrella-shaped discharge port 23 through the connector 21 and the movable part 22. The umbrella-shaped discharge port 23 of the device is provided with multiple discharge chambers. The inlet is narrow and the discharge port has a large coverage area, which can evenly disperse the powder so that it can be placed more widely in the entire glass furnace for easy melting.

[0031] Furthermore, the main component 1 also includes a support member 16 and an adjusting member 17 disposed on the outer periphery of the conveying cylinder 11. The adjusting member 17 includes a sliding member 171 disposed on the outer periphery of the conveying cylinder 11. A sliding outer cylinder 172 is also slidably connected to the outer periphery of the sliding member 171. The adjusting member 17 also includes a base plate 173. A telescopic support rod 174 and a hydraulic telescopic rod 175 are fixed on the base plate 173. The telescopic end of the hydraulic telescopic rod 175 is fixedly connected to the telescopic component of the telescopic support rod 174.

[0032] The support component 16 and the adjusting component 17 are used to support the stable placement of the entire device. The adjusting component 17 is equipped with a hydraulic telescopic rod 175. When in use, the hydraulic telescopic rod 175 is adjusted so that it drives the discharge end of the conveying cylinder 11 to move upward, which facilitates the adjustment of the height of the discharge component 2 and the glass furnace.

[0033] Furthermore, the material distribution chamber 231 is configured as several chambers, so that the glass powder can be more conveniently and evenly diffused and sprinkled into the entire kiln.

[0034] Furthermore, multiple connecting rods 232 are fixed inside the umbrella-shaped feed inlet 23. The dispensing chamber 231 inside the umbrella-shaped feed inlet 23 is isolated by a separate chamber wall. The chamber wall is connected to the outermost feed inlet wall through the connecting rods 232, and is fixed and supported by the connecting rods 232, so that the structure can stand upright.

[0035] Furthermore, the connecting rod 232 has an elliptical cross-section, which prevents residual powder from remaining on top of the glass powder during feeding due to obstruction by the connecting rod 232.

[0036] Furthermore, an adjusting motor 24 is fixed to one end of the connecting member 21. The power shaft of the adjusting motor 24 passes through the connecting member 21 and is fixedly connected to the movable member 22. The adjusting motor 24 is used to adjust the tilt angle of the entire umbrella-shaped material outlet 23. When the adjusting member 17 lifts the material discharge assembly 2, the adjusting motor 24 rotates accordingly, so that the umbrella-shaped material outlet 23 is always set vertically downward.

[0037] Working principle: When using this device, place it next to the glass furnace, and then adjust the height of the discharge assembly 2 through the adjusting component 17. First, the hydraulic telescopic rod 175 moves upward, driving the sliding outer cylinder 172 to move upward, while the support component 16 remains fixed in position, thereby causing the entire conveying cylinder 11 to tilt, ultimately causing the discharge assembly 2 to move upward. After the discharge assembly 2 reaches a certain height, push the entire device above the glass furnace, so that the umbrella-shaped material inlet 23 is placed directly above the furnace. Then, start adding glass powder into the feed hopper 15, start the conveying motor 14, and drive the screw blades to rotate, thus starting the conveying process. The device for conveying glass powder has side blades 13 on the outer periphery of the spiral blades. The side blades 13 and the conveying cylinder 11 form a large inclination angle, which makes it difficult for large quartz particles in the powder to get stuck in the gap between the spiral blades 12 and the conveying cylinder 11. Driven by the spiral blades 12, the powder reaches the discharge assembly 2, and flows out from the umbrella-shaped discharge port 23 through the connecting member 21 and the movable member 22. The umbrella-shaped discharge port 23 of the device is provided with multiple discharge chambers, with a narrow inlet and a large discharge port with a large coverage area, which can evenly disperse the powder and allow it to be placed more widely in the entire glass furnace for easy melting.

[0038] 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.
