Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of glass manufacturing, and relates to a large-drawing-quantity kiln feeding machine structure and a replacement method thereof. BACKGROUND

[0002] In the manufacturing process of substrate glass (such as glass substrate for TFT-LCD and OLED) and cover plate glass (such as mobile phone screen protection cover plate), the kiln is a core thermal equipment, and its stable and efficient operation is crucial to product quality. As a key supporting equipment of the kiln, the feeding machine is responsible for continuously, uniformly and quantitatively feeding glass batch into the kiln, and the reliability of its work and the convenience of its maintenance directly affect the working condition of the kiln and the continuity and efficiency of the production line.

[0003] At present, the top hopper of the kiln feeding machine and the bottom of the intermediate bin in the kiln are connected through a detachable connecting device, and the top of the intermediate bin and the first spiral outlet are connected and sealed by a soft connection. In the existing technology, a steel platform is arranged around the feeding machine, and the intermediate bin is fixedly installed on the steel platform.

[0004] In the prior art, every time the feeding machine is replaced, the detachable connecting device between the top of the feeding machine and the bottom of the intermediate bin needs to be removed, and then the feeding machine as a whole is withdrawn, and the intermediate bin remains stationary. It is very troublesome to remove the detachable connecting device between the top of the feeding machine and the bottom of the intermediate bin every time. On the one hand, the connecting device is relatively heavy and inconvenient to disassemble. Every time the feeding machine is replaced, the operator must first remove the connecting device between the bottom of the intermediate bin and the top hopper of the feeding machine. The device is usually heavy, and the disassembly process requires the use of special tools, which is time-consuming and labor-intensive, greatly increasing the labor intensity of the operator. The complex disassembly process and the limited operating space together cause the time-consuming of replacing the feeding machine to be prolonged every time. For a glass manufacturing line that pursues continuous production, this means longer kiln maintenance time, which directly affects the overall production efficiency and economic benefit. On the other hand, the steel platform for installing the intermediate bin and the support column structure occupy a large amount of space around the feeding machine, resulting in a very narrow operating area on site. The maintenance personnel disassemble the heavy connecting device in this narrow space, which is not only inconvenient to move, but also low in work efficiency, and there is a certain safety risk of bumping.

[0005] In summary, the kiln feeding system based on the split structure and the fixed steel platform in the prior art has obvious defects in design and practicability, and the problems of inconvenient maintenance, low space utilization and low efficiency need to be solved. Therefore, there is an urgent need in the field for a new design of feeding machine structure to completely optimize the maintenance process, liberate the operating space and improve the maintenance efficiency. SUMMARY

[0006] The purpose of this invention is to provide a large-capacity kiln feeder structure and its replacement method to solve the technical problem of low efficiency in replacing and disassembling feeder structures in the prior art, which affects production efficiency.

[0007] To achieve the above objectives, the present invention employs the following technical solution: In a first aspect, the present invention provides a large-capacity kiln feeder structure, including a feeder and an integral hopper disposed on the top of the feeder; the top of the integral hopper is detachably connected to the outlet of the primary screw, and the integral hopper is capable of receiving material from the primary screw and feeding it into the kiln.

[0008] Furthermore, the integral hopper includes an upper hopper section, a middle transition section, and a lower hopper section connected sequentially from top to bottom; the top of the upper hopper section is provided with a feed inlet, which is connected to the outlet of the primary screw; the bottom of the lower hopper section is provided with a discharge outlet, which is connected to the feed inlet of the feeder.

[0009] Furthermore, the upper hopper section is a vertical cylindrical shape; the lower hopper section is an inverted frustum pyramid shape; and the middle transition section is an irregular structure with a circular top cross-section and a rectangular bottom cross-section.

[0010] Furthermore, the upper hopper section, the middle transition section, and the lower hopper section are integrally formed.

[0011] Furthermore, the top of the integral hopper is detachably connected to the outlet of the primary spiral via a flexible connection.

[0012] Furthermore, the flexible connection is made of high-temperature resistant canvas.

[0013] Furthermore, the integral hopper is made of carbon steel or stainless steel.

[0014] Furthermore, the bottom of the feeding machine is equipped with pulleys.

[0015] Secondly, the present invention provides a method for replacing the above-mentioned large-capacity kiln feeder structure, comprising the following steps: When the feeder needs to be replaced, disconnect the flexible connection between the top of the integral hopper and the primary screw. Remove the feeder containing the integrated hopper and replace it with a new feeder.

[0016] Furthermore, in the step of removing the feeder containing the integral hopper, the feeder is removed by means of pulleys at the bottom of the feeder.

[0017] Compared with the prior art, the present invention has the following beneficial effects: This invention discloses a high-capacity kiln feeder structure and its replacement method. The original intermediate hopper and top hopper of the feeder are integrated into a single hopper, eliminating the previous steel platform. This reduces production costs and significantly frees up space around the feeder. Furthermore, with this feeder structure, each replacement only requires quickly disconnecting the flexible connection between the top of the feeder hopper and the primary spiral outlet, then removing the new feeder entirely. This convenient and quick operation greatly reduces operator workload and improves work efficiency. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] In the description of the embodiments of the present invention, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0026] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings: See Figure 1 This invention discloses a high-capacity kiln feeder structure, including a feeder 1 and an integral hopper 2 located on top of the feeder 1. The top of the integral hopper 2 is detachably connected to the outlet of the primary screw 4, and the integral hopper 2 can receive material from the primary screw 4 and feed it into the kiln. The traditional separate intermediate silo 8 and the feeder hopper 3 on top of the feeder are combined into one integral hopper structure, as shown below. Figure 2 As shown in the diagram, this design eliminates the steel platform and support columns 6 originally used to support and fix the intermediate hopper, which not only reduces manufacturing costs but also greatly frees up operating space around the feeder 1. Furthermore, when the feeder 1 needs to be replaced, simply disconnecting the connection between the top of the integral hopper 2 and the upstream equipment (first-stage screw 4) allows the entire feeder 1 unit to be quickly moved out, significantly improving maintenance efficiency and reducing the workload of personnel. This invention has a simple structure, strong practicality, and is suitable for large-scale application.

[0028] In one feasible embodiment of the present invention, the integral hopper 2 includes an upper hopper section, a middle transition section, and a lower hopper section that are sequentially connected and integrally formed from top to bottom; the top of the upper hopper section is provided with a feed inlet, which is connected to the outlet of the primary screw 4; the bottom of the lower hopper section is provided with a discharge outlet, which is connected to the feed inlet of the feeder 1. The upper hopper section is in the shape of a vertical cylinder; the lower hopper section is in the shape of an inverted frustum of a square pyramid; the middle transition section is an irregular structure with a circular top cross section and a rectangular bottom cross section.

[0029] In one feasible embodiment of the present invention, the top of the integral hopper 2 is detachably connected to the outlet of the primary screw 4 via a flexible connection 3. The flexible connection 3 is generally made of high-temperature resistant canvas to ensure mutual insulation between the feeder 1 and the primary screw 4. Both ends of the flexible connection 3 are installed with stainless steel clamps, allowing for quick disassembly during on-site operation. The integral hopper 2 is made of carbon steel or stainless steel. Preferably, since the integral hopper 2 comes into contact with the glass powder used in the kiln, to minimize the impact on the powder, the hopper material is generally selected as 1Cr13 or a similarly low-carbon stainless steel material. The bottom of the feeder 1 is equipped with pulleys 5, which can transform the traditional "integral lifting and transporting" mode into a "smooth rolling movement" mode. This allows operators to easily remove the feeder 1 from its working position or move it to the maintenance area without relying on complex lifting equipment or expending a large amount of manpower.

[0030] This invention discloses a method for replacing the structure of a high-capacity kiln feeder. Includes the following steps: When the feeder needs to be replaced, disconnect the flexible connection 3 between the top of the integral hopper 2 and the primary screw 4; Remove the feeder 1 containing the integral hopper 2 and replace it with a new feeder.

[0031] This invention integrates the traditional feeder hopper 7 and intermediate silo 8 into a single unit, eliminating the steel platform and supporting columns 6 previously used to install and fix the intermediate silo. This reduces production costs by minimizing raw material consumption and separate manufacturing, processing, and assembly processes, while improving equipment reliability and preventing malfunctions such as dust leakage due to loose connections or aging seals, resulting in smoother and more stable material conveying. Furthermore, removing the on-site steel platform significantly frees up space around the feeder 1, eliminating visual and physical obstructions caused by the steel platform and columns, creating a more open and tidy working environment. This spaciousness significantly reduces the risk of accidents such as bumps and trips during maintenance and provides unobstructed access for emergency response. When using the feeder structure of this invention, each time the feeder 1 is replaced, simply disconnect the flexible connection 3 between the top of the feeder hopper 7 and the outlet of the primary spiral 4, then remove the feeder 1 entirely. This convenient and quick operation greatly reduces the workload of operators and improves work efficiency.

[0032] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
