Description

Technical Field

[0001] This invention relates to the technical field of water jacket devices for feeding machines, and particularly to a corrosion-resistant water jacket device for feeding machines. Background Technology

[0002] In the glass manufacturing industry, the feeding machine is a key piece of equipment to ensure a stable supply of raw materials. Its performance directly affects the quality of glass products and production efficiency. The water jacket device of the feeding machine is an important component of the feeding machine in the glass production line. It is mainly used to cool and protect the feeding port area and prevent high temperature environment from damaging the equipment. The water jacket of the traditional feeding machine is usually made of stainless steel and has cooling water flowing inside to reduce the temperature of the feeding port.

[0003] During operation, existing feeder water jackets experience significant temperature differences between their front and rear ends, leading to the formation of condensation droplets on the rear exterior. These droplets combine with corrosive gases such as sulfur dioxide in the exhaust gas, generating acidic liquids. The accumulated acidic liquids corrode the stainless steel water jacket, and prolonged corrosion can cause perforation, resulting in leakage of cooling water. This leaked cooling water comes into contact with the feed material at the feed inlet, causing it to clump and block the inlet, affecting the normal operation of the feeder. Furthermore, the clogged material can fall into the molten glass during feeder replacement, disrupting its stability and leading to a decline in the quality of the glass drawing process. This severely impacts the finished product quality and production efficiency. Therefore, this application provides a corrosion-resistant feeder water jacket device to meet this requirement. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a corrosion-resistant water jacket device for a feeding machine to solve the problems of easy corrosion and clogging of existing water jackets for feeding machines, which affect the finished product quality and production efficiency of glass products.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A corrosion-resistant feeding machine water jacket device includes a water jacket body and a protective shell. A connecting flange is fixedly connected to one end of the water jacket body. A cooling channel is formed inside the pipe wall of the water jacket body, and a circulation component is provided on the outside of the water jacket body. The protective shell is fitted on the outside of the water jacket body at the end away from the circulation component, and an air jet component and a flow guiding component are provided in the protective shell. The circulation component is used for the input and output of cooling water in the cooling channel and is connected to the water jacket body. The air jet component is used to assist in the cooling of the water jacket body and the discharge of acid in the protective shell and is connected to the protective shell. The flow guiding component is used to guide the movement path of the airflow ejected from the air jet component and avoid mutual interference between airflows and is connected to the protective shell.

[0007] Optionally, the circulation component includes an inlet and an outlet symmetrically distributed on the outside of the water jacket body, and a drain outlet located on one side of the inlet is also provided at the bottom of the water jacket body.

[0008] Optionally, the protective shell is fitted onto the end of the water jacket body away from the connecting flange and near the feeding port of the feeder, and a liquid accumulation area is provided on the outside of the protective shell.

[0009] Optionally, the diameter of the liquid accumulation area is larger than the diameter of the protective shell, and a slope is provided at the connection between the liquid accumulation area and the protective shell, and evenly distributed drainage ports are provided at the bottom of the liquid accumulation area.

[0010] Optionally, a gap is provided between the outer surface of the protective shell and the outer surface of the water jacket, and the inner edge of the liquid accumulation area is in contact with the outer surface of the water jacket.

[0011] Optionally, the protective shell has an opening at the end away from the liquid accumulation area, and the jet assembly includes an annular air pipe fixedly connected to the opening of the protective shell. The annular air pipe has evenly distributed air holes facing the outside of the liquid accumulation area, and the annular air pipe is connected to the air supply system through a pipe.

[0012] Optionally, the flow guiding assembly includes uniformly distributed flow guiding plates fixedly connected to the inner wall of the protective shell, and symmetrically distributed limiting plates fixedly connected to the ends of the flow guiding plates.

[0013] Optionally, an input channel is formed between two adjacent guide vanes, and the position of the input channel corresponds one-to-one with the position of the air hole on the annular air tube.

[0014] Optionally, the guide vane and the limiting vane are integrally molded from PTFE material, and their overall cross-section is herringbone-shaped. A weakening groove is provided at the connection between the guide vane and the limiting vane, and both ends of the limiting vane are provided with arc-shaped ends.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] In the above solution, by setting up a protective shell and a liquid accumulation zone, the acid formed after the condensate comes into contact with the exhaust gas can be effectively resisted. The acid is guided to the liquid accumulation zone through the inclined surface between the protective shell and the liquid accumulation zone and is finally discharged through the drain port at the bottom of the liquid accumulation zone. This avoids the water jacket body being corroded by acid during continuous operation and prevents the cooling water in the water jacket body from leaking. It can effectively ensure the finished product quality and production efficiency of glass products.

[0017] By setting up jet components and liquid accumulation zones, compressed air is injected into the gap between the protective shell and the water jacket body through the cooperation of the air supply system and the jet components. On the one hand, this assists in the external cooling of the water jacket body and, together with the cooling water circulation system, assists in the cooling of the water jacket body during operation, thereby enhancing the cooling performance of the entire water jacket device. On the other hand, it can blow the acid generated on the inner wall of the protective shell and the outside of the water jacket body to the liquid accumulation zone, assisting the acid to be discharged from the drain port on the liquid accumulation zone, thus improving the function of the protective shell and the liquid accumulation zone.

[0018] By setting up flow guiding components, on the one hand, a uniformly distributed reinforcing rib structure can be formed on the inner wall of the protective shell, improving the overall structural strength of the protective shell. On the other hand, it can further control the condensate generation area and reduce the condensate generated on the outside of the water jacket body. Finally, adjacent flow guiding plates can also cooperate to form an input channel to guide the airflow ejected from the vent, ensuring the delivery path of the acid after it is purged and avoiding mutual interference between the airflows ejected from the jet assembly.

[0019] By setting the limiting plate and weakening groove in the flow guiding component, the assembly and disassembly operations between the water jacket body and the protective shell are simple and convenient, and there is no need to replace the water jacket body already in use in the existing technology. The modification cost is low and the economy is strong. In addition, the limiting plate and the outside of the water jacket body form an output channel that can work with the input channel to form a complete airflow channel, which enhances the performance of the flow guiding component.

[0038] like Figures 1 to 3As shown, an embodiment of the present invention provides a corrosion-resistant water jacket device for a kiln feeder, including a water jacket body 1 and a protective shell 2. The water jacket body 1 is installed on the kiln feeder near the high-temperature feeding area for cooling and protecting the kiln feeder equipment. A connecting flange 6 is fixedly connected to one end of the water jacket body 1 for connecting and fixing the water jacket body 1 to other pipes. A cooling channel 10 is formed inside the pipe wall of the water jacket body 1, and symmetrically distributed water inlets 3 and water outlets 4 are provided on the outside of the water jacket body 1. Both water inlets 3 and water outlets 4 are connected to the cooling channel 10, but the connection positions are different. The water inlet 3 is connected to the area of ​​the cooling channel 10 closer to the inner wall of the water jacket body 1, while the water outlet 4 is connected to the area of ​​the cooling channel 10 closer to the outside of the water jacket body 1. The cooling water is continuously fed into the cooling channel 10 through the inlet 3 and outlet 4, and then discharged through the outlet 4. During this process, the cooling water contacts the water jacket body 1 and absorbs the high temperature of the water jacket body 1 during operation, preventing the water jacket body 1 from deforming or being damaged due to overheating. Through the continuous circulation of the cooling water, the local temperature of the water jacket body 1 is prevented from being too high, which could lead to material fatigue or failure. The bottom of the water jacket body 1 is also provided with a drain port 5, which is connected to the area of ​​the cooling channel 10 near the outside of the water jacket body 1 and is located on one side of the inlet 3. The drain port 5 is closed by a valve and is opened when the cooling channel 10 needs to be flushed and cleaned to release the sewage in the cooling channel 10.

[0039] In this embodiment, as Figures 1 to 4As shown, the protective shell 2 is fitted onto the rear end of the water jacket body 1, near the feed inlet of the feeder. A liquid accumulation area 7 is located at one end of the protective shell 2, near the feed inlet of the feeder. The diameter of the liquid accumulation area 7 is larger than the diameter of the protective shell 2, and a slope is provided at the connection between the liquid accumulation area 7 and the protective shell 2. Evenly distributed drain ports 9 are provided at the bottom of the liquid accumulation area 7. A gap is provided between the protective shell 2 and the outer surface of the water jacket body 1. The inner edge of the liquid accumulation area 7 is fitted to the outer surface of the water jacket body 1, so that the protective shell 2 and the liquid accumulation area 7 are fitted onto the outer surface of the water jacket body 1. During the operation of the water jacket body 1, the protective shell 2 blocks the rear end of the water jacket body 1, reducing the amount of condensate generated from the outside of the water jacket body 1, thus preventing air from condensing. The condensate in the gas is mostly generated on the outside and inside of the lower-temperature protective shell 2. Both the protective shell 2 and the liquid accumulation area 7 are made of 316L stainless steel and PTFE lining, which can effectively resist the acid formed after the condensate comes into contact with the exhaust gas. The acid is guided to the liquid accumulation area 7 through the inclined surface between the protective shell 2 and the liquid accumulation area 7 and is finally discharged through the drain port 9 at the bottom of the liquid accumulation area 7. This prevents the water jacket body 1 from being corroded by acid during continuous operation, prevents the cooling water in the water jacket body 1 from leaking, and prevents the cooling water from leaking and coming into contact with the feed material to form clumps and blockages. This maintains the normal operation of the feeder and prevents the blockage clumps from falling into the glass melt when the feeder is changed, which would damage the stability of the glass melt and lead to a decrease in the quality of the drawing operation. This ensures the finished product quality and production efficiency of the glass products.

[0040] In this embodiment, as Figures 2 to 7 As shown, the other end of the protective shell 2 is provided with an opening, and an annular air pipe 8 is fixedly connected to the opening of the protective shell 2. The annular air pipe 8 has evenly distributed air holes 15 on the outside facing the liquid accumulation area 7. The annular air pipe 8 is connected to the air supply system through a pipe. While the water jacket body 1 is working continuously, the air supply system also inputs compressed air into the annular air pipe 8 through the pipe. The compressed air enters the gap between the protective shell 2 and the water jacket body 1 through the air holes 15. On the one hand, it assists in the external cooling of the water jacket body 1 and cooperates with the cooling water circulation system to assist in the cooling of the water jacket body 1 during the working process, thereby enhancing the cooling performance of the entire water jacket device. On the other hand, it can blow the acid liquid generated on the inner wall of the protective shell 2 and the outside of the water jacket body 1 to the liquid accumulation area 7, and assist the acid liquid to be discharged from the drain port 9 on the liquid accumulation area 7. Even if a small amount of acid water formed by the combination of condensate and exhaust gas does not slide down the slope between the protective shell 2 and the liquid accumulation area 7, the airflow ejected from the air holes 15 can still sweep the acid liquid to the discharge position, thereby improving the function of the protective shell 2 and the liquid accumulation area 7.

[0041] In this embodiment, as Figures 4 to 8As shown, uniformly distributed guide vanes 11 are fixedly connected to the inner wall of the protective shell 2. Symmetrically distributed limiting plates 12 are fixedly connected to the ends of the guide vanes 11. An input channel 13 is formed between two adjacent guide vanes 11. The position of the input channel 13 corresponds one-to-one with the position of the air hole 15 on the annular air pipe 8. The guide vanes 11 can form a uniformly distributed reinforcing rib structure on the inner wall of the protective shell 2, improving the overall structural strength of the protective shell 2. On the other hand, it can also increase the contact area between the overall structure of the protective shell 2 and the air in the gap between the water jacket body 1 and the protective shell 2. Through its own low temperature and large contact area with the air, it can further control the condensate generation area and reduce the condensate generated outside the water jacket body 1. Finally, the adjacent guide vanes 11 can also cooperate to form the input channel 13 to guide the airflow ejected from the air hole 15, ensuring the purging effect of the airflow on the acid between the water jacket body 1 and the protective shell 2, and ensuring the delivery path of the acid after purging.

[0042] In this embodiment, as Figures 2 to 9As shown, the guide vane 11 and the limiting vane 12 are integrally molded from PTFE material. Their overall cross-section is herringbone-shaped, providing both structural strength and elastic deformation capability. A weakening groove 17 is provided at the connection between the guide vane 11 and the limiting vane 12. Both ends of the limiting vane 12 have arc-shaped ends 16. The weakening groove 17 makes the limiting vane 12 thinner and weaker at the weakening groove 17, making it more prone to deformation under external force. The arc-shaped ends 16 form the arc surfaces at both ends of the guide vane 11 and the limiting vane 12. During the process of the protective shell 2 being fitted onto the outside of the water jacket body 1, the pressure exerted on the water jacket body 1 by the contact between the arc-shaped end 16 and the outside of the water jacket body 1 is decomposed. This allows the pressure exerted by the water jacket body 1 on the limiting plate 12 to cause the two limiting plates 12 on the same guide plate 11 to bend and deform from the weakening groove 17, and then separate and unfold to accumulate elastic potential energy. After the protective shell 2 is completely fitted onto the outside of the water jacket body 1, the protective shell 2 is fixed to the outside of the water jacket body 1 by the elastic force of the guide plate 11, so that the water jacket body 1 and the protective shell 1 are properly fitted together. The assembly and disassembly of the protective shells 2 are simple and convenient, and there is no need to replace the water jacket body 1 already in use in the existing technology. It is only necessary to produce the protective shells 2 according to the size of the water jacket body 1 used. After production, the water jacket body 1 can be directly fitted and modified. The modification cost is low and the economy is strong. After the assembly is completed, the limiting plate 12 fits with the outside of the water jacket body 1, and the limiting plate 12 and the outside of the water jacket body 1 form an output channel 14. Due to the obstruction of the guide plate 11 and the limiting plate 12, the airflow ejected from the air hole 15 flows from the input channel 1. The acid enters through the 3-hole and is partially ejected from the output channel 14, while the other part is ejected from the drain port 9 at the bottom of the accumulation area 7, which assists in the discharge of the acid. The output channel 14 ensures the flow path of the airflow and avoids the airflow from multiple vents 15 from interfering with each other and affecting the purging effect on the acid. Furthermore, due to the structural design of the accumulation area 7 and the protective shell 2, the slope between the accumulation area 7 and the protective shell 2 forms a shield for the acid. The acid that falls into the accumulation area 7 will not be carried out again by the airflow from the output channel 14, but will be discharged directly through the drain port 9 at the bottom of the accumulation area 7.

[0043] This invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this invention. To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0044] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
