Description

Technical Field

[0001] This utility model relates to the technical field of cement production equipment, and in particular to a decomposition furnace narrowing protection device. Background Technology

[0002] The decomposition furnace constriction protection device is installed at the constriction of the decomposition furnace. It can resist high temperature, wear and airflow erosion. It is used in cement production and other similar industrial furnaces and kilns. It has many benefits such as extending equipment life, improving production efficiency, reducing maintenance costs and enhancing safety.

[0003] A search revealed Chinese Patent Publication No. CN216347889U, which discloses a decomposition furnace narrowing protection device. The device includes a decomposition furnace body, a narrowing body, and a smoke chamber. The decomposition furnace body is connected to the smoke chamber via the narrowing body. A set of placement openings are symmetrically arranged on the side of the narrowing body, each with a protective box connected to it. The protective box has a cover at its end. Through the placement openings, a first side rectangular protective body, a first fan-shaped protective body, a second side rectangular protective body, a second fan-shaped protective body, a first middle rectangular protective body, and a second middle rectangular protective body can be inserted into the narrowing body, thus preventing communication between the decomposition furnace body and the smoke chamber. A first fan-shaped protective body is fixedly connected to the middle of the first side rectangular protective body, and a second fan-shaped protective body is connected to the middle of the second side rectangular protective body. The advantages of this invention include: good protective effect, less installation work, and improved work efficiency.

[0004] The aforementioned patent specification mentions the beneficial effects of "opening the cover 6 of the protective housing 5, first inserting the first side rectangular protective body 7 carrying the first fan-shaped protective body 8 into the cavity of the constricted body 2, making the first fan-shaped protective body 8 horizontal, so that the arc-shaped side of the first fan-shaped protective body 8 abuts against one side inner wall of the constricted body 2; then inserting the second side rectangular protective body 9 carrying the second fan-shaped protective body 10 into the cavity of the constricted body 2, making the second fan-shaped protective body 10 horizontal, so that the arc-shaped side of the second fan-shaped protective body 10 abuts against the other side inner wall of the constricted body 2; then sequentially inserting the first middle rectangular protective body 11 and the second middle rectangular protective body 12 into the cavity of the constricted body 2, so that the decomposition furnace body 1 is not connected to the smoke chamber 3; finally, closing the cover 6. At this time, normal construction of the smoke chamber 3 can be guaranteed." Although the aforementioned patent can improve work efficiency, it cannot achieve a sealed installation. Therefore, a decomposition furnace constriction protection device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a protective device for the narrowing of a decomposition furnace, which aims to improve the problem that the narrowing cannot be sealed in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A decomposition furnace necking protection device includes a processing mechanism, a protective mechanism fixedly connected to the top of the processing mechanism, and a connecting mechanism fixedly connected to the outside of the processing mechanism.

[0008] The protective mechanism includes a constricted body, a sealing ring 1 fixedly connected to the bottom of the constricted body, a sealing ring 2 slidably connected to the bottom of the sealing ring 1, a fixing block fixedly connected to the bottom of the sealing ring 2, and a limiting component fixedly connected to the outside of the constricted body.

[0009] Through the above technical solution: the constriction body achieves initial positioning and sealing by sliding engagement between the bottom sealing ring one and the lower sealing ring two, and then connecting to the fixing block. The limiting component stabilizes the constriction body, preventing it from shaking or shifting. When the decomposition furnace is running, high-temperature materials and high-speed airflow impact the constriction body, and all components of the protective mechanism work together. Sealing rings one and two are compressed and tightly fitted, preventing material and airflow from overflowing. The fixing block provides stable support for the entire protective mechanism, and the limiting component further enhances the stability of the constriction body, ensuring that the protective device continuously and effectively protects the decomposition furnace constriction under harsh operating conditions.

[0010] As a further description of the above technical solution:

[0011] The limiting component includes a fixing plate, the inner side of which is fixedly connected to the outer side of the constricted body, a rotating plate rotatably connected to the outer side of the fixing plate, and a limiting shell slidably connected to the outer side of the rotating plate.

[0012] The above technical solution works as follows: When installing the necking body, the fixing plate is aligned with the limiting shell. During the pressing process, the inner wall of the limiting shell squeezes the rotating plate, causing it to rotate around the fixing plate. After installation, the rotating plate slides to a specific position on the limiting shell, and the limiting shell restricts the position of the rotating plate, thereby firmly fixing the necking body and preventing it from shifting or shaking.

[0013] As a further description of the above technical solution:

[0014] The processing mechanism includes a decomposition furnace, with two discharge ports fixedly connected to the outside of the decomposition furnace and a feed port fixedly connected to the other side of the decomposition furnace;

[0015] The above technical solution involves raw materials entering the decomposition furnace through the feed inlet, where they undergo preheating and decomposition. The reacted materials are discharged through two outlets for further processing in subsequent stages. The feed inlet controls the input of raw materials, while the outlets ensure timely output, working together to maintain the efficient and stable operation of the decomposition furnace.

[0016] As a further description of the above technical solution:

[0017] The connecting mechanism includes a transmission tube, a limiting post fixedly connected to the bottom of the transmission tube, a fixed post slidably connected to the outside of the limiting post, a plurality of ball bearings slidably connected to the inside of the fixed post, and a sliding post slidably connected to the outside of the fixed post.

[0018] The above technical solution allows for the following: When installing the transmission tube, pressing down the sliding pin causes the ball bearings to disengage from the limiting pin, allowing the limiting pin to slide into the fixing pin. Releasing the sliding pin allows it to reset under elastic force, and the ball bearings press against the limiting pin, securing the transmission tube. For disassembly, pressing down the sliding pin again allows the ball bearings to move aside, enabling the transmission tube to be pulled out, thus achieving convenient connection and separation.

[0019] As a further description of the above technical solution:

[0020] A spring is fixedly connected inside the rotating plate, and the other end of the spring is fixedly connected to the outside of the fixed plate.

[0021] The above technical solution works as follows: when the rotating plate is squeezed and rotated by the limiting shell, the spring is compressed and stores elastic potential energy. Once installed in place, the limiting shell no longer squeezes the rotating plate, and the spring releases its elastic potential energy, pushing the rotating plate back, so that one end of the rotating plate is tightly pressed against the inner wall of the limiting shell, ensuring a stable connection between the fixing plate and the limiting shell, and ensuring a secure installation of the constricted body.

[0022] As a further description of the above technical solution:

[0023] The outer side of the ball is slidably connected to the inside of the sliding column, and the outer side of the ball is slidably connected to the outside of the transmission tube.

[0024] The above technical solution works as follows: When installing the transmission tube, the sliding post moves downward, allowing the ball bearings to slide freely within the sliding post, enabling the limiting post to be smoothly inserted into the fixing post. Afterward, the sliding post returns to its original position, and the ball bearings, positioned between the sliding post and the transmission tube, are both constrained by the sliding post and abut against the limiting post on the outside of the transmission tube, thus firmly fixing the transmission tube and ensuring a stable connection.

[0025] As a further description of the above technical solution:

[0026] A second spring is fixedly connected inside the sliding column, and the other end of the second spring is fixedly connected to the outside of the fixed column.

[0027] The above technical solution works as follows: when the sliding column slides downwards, the second spring is compressed, storing elastic potential energy. After the limiting column of the transmission tube slides into the fixed column, the sliding column is released, and the second spring releases its elastic potential energy, pushing the sliding column upwards to reset. During the reset process, the sliding column restricts the ball bearings, thereby firmly fixing the transmission tube in the set position.

[0028] As a further description of the above technical solution:

[0029] A storage tube is fixedly connected to the bottom of the fixed column, and one side of the storage tube is fixedly connected to the outside of the decomposition furnace.

[0030] The above technical solution involves the following process: Materials that have completed the reaction in the decomposition furnace are discharged through the outlet, pass through a transfer pipe into a fixed column, and then flow into a storage pipe at the bottom for temporary storage. One side of the storage pipe is connected to the decomposition furnace to ensure continuous material transfer. The entire process is efficiently integrated, allowing for the orderly storage of decomposed materials for convenient subsequent retrieval and processing.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, the constricted body is fitted with a fixing plate and a sealing ring one, the sealing ring one is fitted with a sealing ring two, the sealing ring two is fitted with a fixing block, the fixing plate is fitted with a rotating plate, and the rotating plate is fitted with a limiting shell and a spring one, thereby achieving a sealed installation of the constricted body. The constricted body, through its cooperation with the fixing plate, sealing ring one, sealing ring two, and fixing block, can form a multi-layer sealing structure. When the sealing ring one and sealing ring two are compressed, they will fill the gaps between the components, effectively preventing the leakage of gas, dust, or other substances, ensuring the stability and sealing of the internal environment of the constricted protective device of the decomposition furnace, which is conducive to maintaining the normal working state of the decomposition furnace and reducing the possibility of heat loss and material leakage.

[0033] 2. In this utility model, the transmission tube is combined with a limiting post, the limiting post is combined with a ball bearing, the ball bearing is combined with a sliding post, and the sliding post is combined with a spring, thereby achieving the effect of quick disassembly or installation of the transmission tube. No complicated tools or professional skills are required. Operators can complete the disassembly and installation of the transmission tube by simply sliding and pulling, which reduces the difficulty of operation and improves work efficiency.

[0040] 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.

[0041] Reference Figures 1 to 3 The present invention provides an embodiment of a decomposition furnace necking protection device, comprising a processing mechanism 1. The processing mechanism 1 undertakes the core material processing task in the whole system. It can provide suitable space and conditions for the internal chemical reaction and ensure the efficient conversion of materials under specific conditions. A protective mechanism 2 is fixedly connected to the top of the processing mechanism 1. The protective mechanism 2 is installed on the top of the processing mechanism 1 and can effectively block the direct impact and erosion of high temperature, high speed airflow and materials on the top of the processing mechanism 1, greatly reducing the risk of equipment damage and extending the service life of the processing mechanism 1.

[0042] A connecting mechanism 3 is fixedly connected to the outside of the processing mechanism 1. The connecting mechanism 3 is tightly attached to the outside of the processing mechanism 1 and is responsible for establishing a stable connection between the processing mechanism 1 and other external equipment. This ensures that materials can be accurately and efficiently transported between the various devices, promoting the continuity of the entire production process. The protective mechanism 2 includes a constricted body 21. The constricted body 21 is located in a key part of the protective mechanism 2. Its unique constricted structure can optimize the airflow distribution inside the processing mechanism 1, allowing the materials and airflow to mix more thoroughly and significantly improving the reaction efficiency. A sealing ring 22 is fixedly connected to the bottom of the constricted body 21. The sealing ring 22 is installed at the bottom of the constricted body 21 and can initially isolate the materials and airflow inside the processing mechanism 1, preventing them from leaking from the gap at the bottom of the constricted body 21, thus providing a basic guarantee for protection.

[0043] A second sealing ring 23 is slidably connected to the bottom of sealing ring 1 22, and a fixing block 24 is fixedly connected to the bottom of sealing ring 23. Sealing ring 23 is located below sealing ring 1 22 and works in conjunction with sealing ring 1 22 to further enhance the sealing effect, greatly reduce the leakage of materials and airflow, and ensure the stability of the internal environment of the processing mechanism 1. A limiting component 25 is fixedly connected to the outside of the constriction body 21. The limiting component 25 is tightly connected to the outside of the constriction body 21 and can effectively prevent the constriction body 21 from being displaced or shaking due to airflow impact or equipment vibration during operation, thereby enhancing the stability of the constriction body 21 and the entire protective mechanism 2.

[0044] Specifically, the processing mechanism 1, as the core, provides space and conditions for the chemical reaction of materials to achieve efficient conversion. The protective mechanism 2 at the top optimizes the airflow distribution and improves the reaction efficiency through the constriction body 21. The sealing ring 1 22 and sealing ring 23 at the bottom work together to block material and airflow leakage, ensuring the stability of the internal environment, greatly reducing the risk of equipment damage and extending service life. The connecting mechanism 3 on the outside establishes a stable connection with external equipment, ensuring accurate and efficient material delivery and promoting the continuity of the production process. The limiting component 25 in the protective mechanism 2 is tightly connected to the outside of the constriction body 21, effectively resisting airflow impact and equipment vibration, preventing the constriction body 21 from shifting or shaking, and enhancing the stability of the constriction body 2 and the entire protective mechanism 2. All parts work together to ensure the stable and efficient operation of the entire system.

[0045] The limiting component 25 includes a fixing plate 251, which serves as the basic connecting component of the limiting component 25. Its function is to be firmly attached to the constriction body 21, providing a reliable carrier for the installation and operation of other components. This allows the limiting component 25 to act precisely on the constriction body 21. The inner side of the fixing plate 251 is fixedly connected to the outer side of the constriction body 21. This inner connection method ensures that the fixing plate 251 and the constriction body 21 fit tightly together, which can effectively transmit the limiting force from other components on the constriction body 21, allowing the constriction body 21 to maintain a stable position during operation and avoid displacement.

[0046] A rotating plate 252 is rotatably connected to the outside of the fixed plate 251. The rotating plate 252 can rotate flexibly around the fixed plate 251 and plays a key role in the installation and disassembly of the constricted body 21. When installation or disassembly is required, the rotating plate 252 can change its position by rotation to cooperate with other components to complete the corresponding operation. A limiting shell 254 is slidably connected to the outside of the rotating plate 252. The limiting shell 254 guides and constrains the sliding of the rotating plate 252. When installing the constricted body 21, the rotating plate 252 slides in the limiting shell 254 until it reaches a specific position and is locked, thereby achieving a firm fixation of the constricted body 21. A spring 253 is fixedly connected inside the rotating plate 252. The spring 253 provides elastic restoring force to the rotating plate 252. When the rotating plate 252 is rotated by external pressure, the spring 253 is compressed and stores energy. Once the external pressure disappears, the spring 253 releases energy to push the rotating plate 252 to reset.

[0047] The other end of spring 253 is fixedly connected to the outside of fixed plate 251. This connection method ensures that spring 253 can stably provide elastic support for rotating plate 252, making the operation of rotating plate 252 between fixed plate 251 and limiting shell 254 more stable and reliable, and ensuring the limiting effect of limiting component 25 on constricted body 21.

[0048] Specifically, when the limiting component 25 is working, the inner side of the fixed plate 251 is firmly connected to the outer side of the constricted body 21, closely fitting and transmitting the limiting force to maintain the stable working position of the constricted body 21. The rotating plate 252, which is rotatably connected to the outer side, can flexibly rotate around the fixed plate 251 when installing or removing the constricted body 21, changing its position to cooperate with the operation. The limiting shell 254 on its outer side serves as a sliding guide for the rotating plate 252 and locks it in a specific position to achieve a firm fixation of the constricted body 21. The spring 253 fixed inside the rotating plate 252 is connected to the outer side of the fixed plate 251 at one end. When the rotating plate 252 is squeezed and rotated by external pressure, the spring 253 is compressed and stores energy; when the squeezing force disappears, the spring 253 releases energy to push the rotating plate 252 to reset, ensuring that the rotating plate 252 operates stably between the fixed plate 251 and the limiting shell 254, reliably exerting the limiting effect of the limiting component 25 on the constricted body 21, and ensuring the normal operation of the protective mechanism 2.

[0049] Reference Figure 1 , Figure 2 and Figure 4The processing mechanism 1 includes a decomposition furnace 11, which is the core reaction device in the entire production process. It provides specific space and conditions for the preheating and decomposition of materials, enabling the raw materials to be efficiently converted in a high-temperature environment, which greatly improves production efficiency. Two discharge ports 12 are fixedly connected to the outside of the decomposition furnace 11. These two discharge ports 12 are evenly distributed on the outside of the decomposition furnace 11. Their function is to discharge the materials that have completed the reaction in the decomposition furnace 11 in a timely manner, providing raw materials for subsequent processes. The reasonable quantity and position design ensures the high efficiency and balance of material output.

[0050] A feed inlet 13 is fixedly connected to the other side of the decomposition furnace 11. The feed inlet 13 is installed on the other side of the decomposition furnace 11 and undertakes the key task of accurately feeding the raw materials into the decomposition furnace 11. Its position design ensures that the raw materials can smoothly enter the decomposition furnace 11 and be evenly dispersed in the furnace, laying a good foundation for subsequent reactions.

[0051] Specifically, the core of processing mechanism 1 is the decomposition furnace 11, which creates a high-temperature environment for preheating and decomposing materials, promoting efficient conversion of raw materials and significantly improving production efficiency. Two symmetrically distributed discharge ports 12 on the outside of the decomposition furnace 11 can discharge the reacted materials in a timely manner. Its reasonable layout ensures efficient and balanced material output, providing a stable supply of raw materials for subsequent processes. On the other side of the decomposition furnace 11, the feed port 13 precisely undertakes the important task of feeding in raw materials. Its carefully designed position allows the raw materials to enter the decomposition furnace 11 smoothly and be evenly dispersed in the furnace, laying the foundation for the raw materials to fully contact the high-temperature environment and react efficiently. The feed port 13 and the discharge port 12 work together to ensure the continuous reaction of the feed and connect the discharge to the subsequent production links. Working in tandem with the decomposition furnace 11, they ensure the efficient and stable operation of the entire production process.

[0052] The connecting mechanism 3 includes a transmission pipe 31. The main function of the transmission pipe 31 is to smoothly and efficiently transfer the material in the decomposition furnace 11 to other equipment, ensuring the orderly flow of material between different stages and ensuring the continuity of the production process. A limiting column 32 is fixedly connected to the bottom of the transmission pipe 31. The limiting column 32 is tightly connected to the transmission pipe 31, providing a key positioning and support point for the installation and fixation of the transmission pipe 31, so that the transmission pipe 31 can remain stable during operation and avoid shaking or displacement.

[0053] A fixed column 33 is slidably connected to the outside of the limiting column 32. The fixed column 33 provides a sliding track and a stable support structure for the limiting column 32. The sliding connection between the two facilitates the installation and disassembly of the transmission pipe 31, while ensuring the tightness and stability of the connection. A storage pipe 37 is fixedly connected to the bottom of the fixed column 33. The storage pipe 37 can temporarily store the material transported from the transmission pipe 31, playing a role in buffering and regulating the material flow rate, ensuring the stability and continuity of material supply between the decomposition furnace 11 and subsequent processes. One side of the storage pipe 37 is fixedly connected to the outside of the decomposition furnace 11. This connection method makes the storage pipe 37 and the decomposition furnace 11 form a whole, which facilitates the direct flow of material from the decomposition furnace 11 into the storage pipe 37, reducing energy loss and leakage risk during material transmission.

[0054] Multiple balls 34 are slidably connected inside the fixed post 33. The balls 34 can roll flexibly inside the fixed post 33. When the limiting post 32 of the transmission tube 31 is inserted into or pulled out of the fixed post 33, the balls 34 can reduce friction, making the operation smoother and enhancing the stability of the connection. The outer side of the balls 34 is slidably connected to the outer side of the transmission tube 31. This connection method allows the balls 34 to fit tightly against the transmission tube 31. Under the action of the fixed post 33, the balls 34 apply uniform pressure to the transmission tube 31, further ensuring the fixing effect of the transmission tube 31.

[0055] A sliding post 35 is slidably connected to the outside of the fixed post 33. The sliding post 35 can slide along the outside of the fixed post 33. By controlling the position of the sliding post 35, the ball 34 can be restricted and released, thereby facilitating the installation and disassembly of the transmission tube 31. The outside of the ball 34 is slidably connected to the inside of the sliding post 35. When the sliding post 35 slides, it can drive the ball 34 to move, thereby locking and unlocking the limiting post 32 of the transmission tube 31. This structural design makes the connection and disassembly of the transmission tube 31 more convenient and reliable.

[0056] A second spring 36 is fixedly connected inside the sliding column 35. The second spring 36 provides elastic force to the sliding column 35. When the sliding column 35 is operated to compress the second spring 36, the second spring 36 stores elastic potential energy. When the external force disappears, the second spring 36 releases the elastic potential energy and pushes the sliding column 35 to reset, ensuring the fixing effect on the transmission tube 31. The other end of the second spring 36 is fixedly connected to the outside of the fixed column 33. This connection method allows the second spring 36 to play a stable role, ensuring that the sliding column 35 can always provide stable elastic support during the sliding process outside the fixed column 33, maintaining the normal working state of the connecting mechanism 3.

[0057] Specifically, in the connecting mechanism 3, the transmission pipe 31 is responsible for smoothly and efficiently transporting the material in the decomposition furnace 11 to other equipment, ensuring continuous production. The limiting column 32 at its bottom positions and supports the transmission pipe 31, ensuring stable operation. The limiting column 32 is slidably connected to the fixed column 33, facilitating the installation and disassembly of the transmission pipe 31 and ensuring a tight connection. The storage pipe 37 at the bottom of the fixed column 33 buffers and regulates the material flow rate, and is connected to the decomposition furnace 11, reducing material transmission loss and leakage. The ball bearings 34 inside the fixed column 33 reduce friction and enhance connection stability when the limiting column 32 is inserted or removed, and fit tightly against the transmission pipe 31. The sliding column 35 controls the limiting and releasing of the ball bearings 34 by sliding along the outside of the fixed column 33, enabling convenient installation and disassembly of the transmission pipe 31. The spring 36 inside the sliding column 35 stores energy when the sliding column 35 is compressed, and releases elastic potential energy after the external force disappears to push it back to its original position, stably providing elastic support, maintaining the normal operation of the connecting mechanism 3, and ensuring smooth material transmission.

[0058] Working principle: When it is necessary to remove the constriction body 21 from the top of the fixing block 24, the rotating plate 252 can be pressed down to compress the spring 253. After the spring 253 is compressed by the rotating plate 252, the constriction body 21 can be removed from the top of the fixing block 24. When it is necessary to reinstall the constriction body 21, the outer side of the fixing plate 251 can be aligned with the inside of the limiting shell 254. Then, the constriction body 21 can be pressed down to make the inner wall of the limiting shell 254 align with the inner wall of the limiting shell 254. The rotating plate 252 is compressed, and the interior of the limiting shell 254 has a groove that fits the outer side of the rotating plate 252. When the rotating plate 252 slides to the outside of the groove, the spring 253 will push the rotating plate 252 up, so that one end of the rotating plate 252 abuts against the inner wall of the limiting shell 254. At this time, the bottom of the constricted body 21 is fixedly connected to the top of the fixing block 24, and the fixing block 24 is fixedly connected to the sealing ring 23. Then, by compressing the sealing ring 22 and the sealing ring 23, the sealing installation effect can be achieved.

[0059] When the transmission tube 31 needs to be disassembled for maintenance, the sliding post 35 can be slid downwards to release the multiple balls 34 restricted inside the sliding post 35. Then, the transmission tube 31 can be pulled upwards. The limiting post 32 is fixedly connected to the outside of the transmission tube 31. Pulling the transmission tube 31 upwards will cause the limiting post 32 to squeeze the multiple balls 34 into the inside of the sliding post 35. To reinstall the transmission tube 31, the sliding post 35 can be pulled downwards again. Then, the limiting post 32 will slide into the inside of the fixed post 33. Then, the sliding post 35 will be released. The sliding post 35 is connected to a second spring 36. When the second spring 36 slides downwards, it will be compressed. When the sliding post 35 is released, the second spring 36 will release the pressure, thereby pushing the sliding post 35 back to its original position. The sliding post 35, which has been pushed back to its original position, will restrict the multiple balls 34 inside the fixed post 33, thereby pressing the balls 34 against the outside of the limiting post 32 and confining them inside the fixed post 33.
