Description

Technical Field

[0001] This invention relates to the field of steel strand processing technology, and more specifically, to a device for stabilizing steel strands after twisting. Background Technology

[0002] In modern industrial production, steel strand, as an important building and industrial material, is widely used in bridge construction, soil and rock anchoring, prestressed concrete structures, and many other fields. The stability treatment of steel strand after twisting plays a crucial role in ensuring its product quality and performance. Currently, common steel strand stability treatment processes, such as tension adjustment, heat treatment, and surface coating, are widely used and continuously optimized in actual production.

[0003] However, during the stabilization treatment of steel strands, especially in the heat treatment process using a stabilization furnace, a significant problem gradually emerges: the generation of flue gas. During the heat treatment process, oil stains, impurities, and auxiliary materials that may be present on the surface of the steel strands will undergo chemical reactions such as oxidation and decomposition under high temperatures, resulting in a large amount of flue gas. This flue gas has a complex composition, containing not only harmful gases such as sulfur dioxide and nitrogen oxides, but also a large amount of dust particles and volatile organic compounds.

[0004] If these fumes are not effectively treated, they will severely pollute the working environment of the production workshop, endangering the health of operators. Long-term exposure to such an environment will make workers susceptible to respiratory and lung diseases. Furthermore, the direct release of untreated fumes into the atmosphere will have a detrimental impact on the surrounding ecological environment, exacerbating air pollution and affecting regional air quality. Therefore, we propose a stabilization treatment device for steel strand after twisting. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a stabilization treatment device for twisted steel strands, comprising a stabilization furnace, wherein a flue gas pipe communicating with the furnace is provided at the top, a transfer plate is fixedly connected to the other end of the flue gas pipe, a receiving groove is provided on the outer wall of the transfer plate, and a connecting groove is provided at the end of the transfer plate, the connecting groove being crescent-shaped, a guide pipe is fixedly connected to the end of the transfer plate away from the flue gas pipe, the guide pipe and the flue gas pipe are connected through the connecting groove, an exhaust fan is provided inside the guide pipe, a fixing plate is fixedly connected to the bottom of the transfer plate, a motor is fixedly connected to the bottom of the fixing plate, the main shaft of the motor passes through the fixing plate to the transfer plate, and a transmission column is fixedly connected to the end of the main shaft of the motor, and a treatment mechanism for treating flue gas is provided outside the transmission column.

[0007] Preferably, the processing mechanism includes multiple pairs of limiting rings disposed on the outer wall of the transmission column. Each limiting ring has a crescent-shaped structure, and a crescent-shaped filter plate is disposed in the middle of the limiting ring. The outer wall of each limiting ring is provided with multiple annular grooves that penetrate it. The inner wall of each annular groove is fixedly connected with a first baffle. A guide post is disposed between the first baffles. The inner wall of the annular groove is also fixedly connected with a second baffle, which is located between the first baffles. The two ends of the guide post penetrate the second baffle and are slidably connected to the inner wall of the penetration point. A spring is sleeved on the outer wall of the guide post. The two ends of the spring are fixedly connected to the opposite side of the second baffle. The two ends of the guide post are fixedly connected with a third baffle.

[0008] Preferably, the outer wall of each limiting ring is fixedly connected with a convex block, and the outer wall of the transmission column is provided with a plurality of convex grooves corresponding to the convex blocks, and one end of the convex groove passes through the transmission column, and the convex blocks are respectively located in the convex grooves.

[0009] Preferably, the outer wall of the transfer plate is hinged with a pair of protective members, the middle part of which is hollow, and the hollow part of the protective members covers the limiting ring inside.

[0010] Preferably, the inner wall of each limiting ring is fixedly connected with a rubber sealing ring, the sealing ring being a crescent-shaped structure corresponding to the limiting ring, and the inner wall of the sealing ring being fixedly connected to the upper and lower outer edges of the filter plate respectively.

[0011] Preferably, the outer and inner edges of adjacent limiting rings abut against each other, and the abutment point of the inner and outer edges of the limiting rings is sealed after abutting.

[0012] Preferably, the outer edges of the limiting rings are inclined to form guide portions, and the guide portions on two opposite guide rings are inclined in opposite directions.

[0013] Preferably, the wall ends of the limiting ring are all fixedly connected to sealing elements, and the sealing elements are crescent-shaped structures corresponding to the limiting ring.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting up a stabilization furnace, exhaust pipe, transfer plate, collection tank, connecting tank, guide pipe, exhaust fan, fixing plate, motor, transmission column, and processing mechanism, can treat the flue gas with complex composition, containing harmful gases, dust particles, and volatile organic compounds generated during heat treatment. This avoids serious pollution of the working environment of the production workshop by the flue gas, protects the health of the operators, and also prevents untreated flue gas from being directly emitted into the atmosphere, causing adverse effects on the surrounding ecological environment, reducing air pollution, and improving regional air quality.

[0015] 2. In this invention, when the filter plate needs to be replaced, the new filter plate can smoothly enter the working position while the motor drives the transmission column to rotate, achieving seamless connection with the original filter plate and ensuring uninterrupted treatment of flue gas. This not only guarantees the continuous and stable operation of the stabilization furnace but also avoids flue gas emission problems caused by treatment interruption, greatly improving production efficiency and environmental performance.

[0016] 3. The limiting rings in this invention are interconnected by springs, guide posts and other structures. When the equipment is running, these structures can make the limiting rings tightly abut against the inner wall of the collection tank, forming a good sealing effect. Whether the limiting rings drive the filter plate to rotate or the filter plate is working normally, it can effectively prevent the flue gas from leaking from the collection tank, ensuring that the entire treatment process is carried out in a relatively closed environment, and improving the reliability of the equipment for flue gas treatment.

[0017] 4. The inclined setting of the guide part on the limiting ring in this invention provides a guiding function for the limiting ring to be inserted into the receiving groove during rotation. When the motor drives the transmission column to rotate, the limiting ring rotates and approaches the receiving groove, guiding it so that the limiting ring can be smoothly and stably inserted into the receiving groove, reducing the jamming phenomenon during the operation of the equipment and ensuring the smoothness and stability of the processing mechanism.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Example 1

[0021] like Figure 1-7 As shown, a stabilization treatment device for twisted steel strands includes a stabilization furnace 1. A flue gas pipe 2, communicating with the furnace's interior, is installed at the top of the furnace 1. A transfer plate 3 is fixedly connected to the other end of the flue gas pipe 2. A receiving groove 4 is formed on the outer wall of the transfer plate 3. A connecting groove 5, crescent-shaped, is formed at the end of the transfer plate 3 that passes through it. A guide pipe 6 is fixedly connected to the end of the transfer plate 3 away from the flue gas pipe 2. The guide pipe 6 and the flue gas pipe 2 are connected through the connecting groove 5. An exhaust fan 7 is installed inside the guide pipe 6. A fixing plate 8 is fixedly connected to the bottom of the transfer plate 3. A motor 9 is fixedly connected to the bottom of the fixing plate 8. The main shaft of the motor 9 passes through the fixing plate 8 and the transfer plate 3. A transmission column 10 is fixedly connected to the end of the main shaft of the motor 9. A treatment mechanism for treating the flue gas is provided outside the transmission column 10.

[0022] The processing mechanism includes multiple pairs of limiting rings 11 disposed on the outer wall of the transmission column 10. Each limiting ring 11 has a crescent-shaped structure. A crescent-shaped filter plate 12 is disposed in the middle of the limiting ring 11. The outer wall of each limiting ring 11 is provided with multiple annular grooves 13 that pass through it. The inner wall of each annular groove 13 is fixedly connected to a first baffle 14. A guide post 15 is disposed between the first baffles 14. The inner wall of the annular groove 13 is also fixedly connected to a second baffle 16, which is located between the first baffles 14. The two ends of the guide post 15 pass through the second baffle 16 and are slidably connected to the inner wall of the part through which they are passed. A spring 17 is sleeved on the outer wall of the guide post 15. The two ends of the spring 17 are fixedly connected to the opposite side of the second baffle 16. The two ends of the guide post 15 are fixedly connected to a third baffle 18.

[0023] Specifically, the stabilization furnace 1 is started and heated to carry out a heat treatment process on the steel strand placed inside, thereby generating flue gas. At this time, the exhaust fan 7 starts to operate and quickly extracts the flue gas generated in the stabilization furnace 1. The flue gas flows along the exhaust pipe 2, which is tightly connected to the top of the stabilization furnace 1, towards the transfer plate 3. After the flue gas reaches the transfer plate 3, it flows into the connecting groove 5 and is processed by the filter plate 12 before entering the guide pipe 6 and then being discharged, thus completing the treatment of the flue gas. As time goes by, after continuously filtering a large amount of flue gas, a large amount of dust particles will gradually accumulate on the surface of the filter plate 12, and the adsorption performance will also decrease, resulting in a reduction in filtration performance. At this time, the filter plate 12 needs to be replaced. The operator starts the motor 9, and the motor 9 rotates to drive the transmission column 10 connected to it. Multiple crescent-shaped limiting rings 11 are installed on the outer wall of the transmission column 10. Under the drive of the transmission column 10, the limiting rings 11 start to rotate. Since the filter plate 12 is firmly connected to the limiting rings 11, the filter plate 12 originally stored in the storage groove 4 is smoothly rotated out of the storage groove 4 under the drive of the limiting rings 11. During the rotation process, the filter plate 12 gradually approaches the working filter plate 12. As the transmission column 10 continues to rotate, the filter plate 12 accurately replaces the working filter plate 12, achieving a seamless connection. The original working filter plate 12 is rotated out of the storage groove 4 under the drive of the limiting rings 11. Thanks to the unique crescent-shaped design of the filter plate 12 and the limiting ring 11, as well as the special structure of the connecting groove 5, the filter plate 12 can smoothly enter the working position while the motor 9 drives the transmission column 10 to rotate, achieving seamless connection with the original filter plate 12. This ensures uninterrupted treatment of flue gas, which not only guarantees the continuous and stable operation of the stabilization furnace 1 and avoids flue gas emission problems caused by treatment interruption, but also greatly improves production efficiency, reduces the risk of environmental pollution, enhances environmental protection performance, and effectively achieves synergistic progress between production and environmental protection. The spring 17 in the annular groove 13 on the limiting ring 11 pushes the second baffle 16 with its own elasticity, so that the second baffle 16 pushes the limiting ring 11, making the limiting ring 11 tightly abut against the inner wall of the receiving groove 4, forming a good sealing effect. Whether the limiting ring 11 drives the filter plate 12 to rotate or the filter plate 12 is working normally, it can effectively prevent the flue gas from leaking from the receiving groove 4, ensuring that the entire treatment process is carried out in a relatively closed environment, improving the reliability of the equipment for flue gas treatment. The first baffle 14 can prevent the guide column 15 from being pulled out of the annular groove 13, and the third baffle 18 can prevent the second baffle 16 from being pulled out, thereby ensuring the normal operation of the guide column 15 and the spring 17.

[0024] Furthermore, the outer wall of the limiting ring 11 is fixedly connected with a convex block 19, and the outer wall of the transmission column 10 is provided with a plurality of convex grooves 20 corresponding to the convex block 19, and one end of the convex groove 20 passes through the transmission column 10, and the convex blocks 19 are all located in the convex groove 20 respectively.

[0025] Specifically, the convex block 19 can slide within the convex groove 20, and the convex block 19 is fixedly connected to the limiting ring 11, thereby ensuring the normal movement of the limiting ring 11. One end of the convex groove 20 passes through the transmission column 10, which allows the convex block 19 to be pulled out of the convex groove 20, thereby allowing the limiting ring 11 to be removed, which facilitates tilting or replacing the filter plate 12.

[0026] Furthermore, a pair of protective members 21 are hinged to the outer wall of the transfer plate 3. The middle part of the protective member 21 is hollow, and the hollow part of the protective member 21 covers the limiting ring 11 inside.

[0027] Specifically, the protective component 21 can cover the filter plate 12 that is no longer being treated with flue gas, thereby protecting the filter plate 12 and preventing dust from contaminating the clean filter plate 12.

[0028] Furthermore, the inner wall of the limiting ring 11 is fixedly connected with a rubber sealing ring 22. The sealing ring 22 is a crescent-shaped structure corresponding to the limiting ring 11, and the inner wall of the sealing ring 22 is fixedly connected to the upper and lower outer edges of the filter plate 12 respectively.

[0029] Specifically, the sealing ring 22 can seal the space between the limiting rings 11, and the rubber sealing ring 22 can be pulled by the limiting rings 11 when they move, so as not to affect the normal movement of the limiting rings 11, thereby further increasing the treatment effect of the flue gas.

[0030] Furthermore, the outer and inner edges of adjacent limiting rings 11 abut against each other, and the abutment point of the inner and outer edges of the limiting rings 11 is sealed after they abut against each other.

[0031] Specifically, by replacing the working filter plate 12 with the filter plate 12 to achieve a seamless connection, the leakage of flue gas from the limiting rings 11 is prevented, thereby further ensuring the treatment effect of the flue gas.

[0032] Furthermore, the outer edges of the limiting rings 11 are inclined to form guide portions 23, and the guide portions 23 on the two opposite guide rings are inclined in opposite directions.

[0033] Specifically, the inclined setting of the guide part 23 provides a guiding function for the limit ring 11 to be inserted into the storage groove 4 during rotation. When the motor 9 drives the transmission column 10 to rotate, the limit ring 11 rotates and approaches the storage groove 4, guiding it so that the limit ring 11 can be inserted into the storage groove 4 smoothly and stably, reducing the jamming phenomenon during the operation of the equipment and ensuring the smoothness and stability of the processing mechanism.

[0034] Furthermore, sealing elements 24 are fixedly connected to the end of the wall of the limiting ring 11. The sealing elements 24 are crescent-shaped structures corresponding to the limiting ring 11.

[0035] Specifically, by using the sealing element 24, the limiting ring 11 can increase the sealing effect when it abuts against the inner wall of the receiving groove 4 under the elastic force of the spring 17, thereby further preventing flue gas leakage.

[0036] Working principle: This embodiment provides a stabilization treatment device for steel strand after twisting. The stabilization furnace 1 is started and heated to carry out a heat treatment process on the steel strand placed in it, thereby generating flue gas. At this time, the exhaust fan 7 starts to operate and quickly extracts the flue gas generated in the stabilization furnace 1. The flue gas flows along the exhaust pipe 2, which is tightly connected to the top of the stabilization furnace 1, towards the transfer plate 3. After the flue gas reaches the transfer plate 3, it flows into the connecting groove 5 and is processed by the filter plate 12 before entering the guide pipe 6 and then being discharged, thus completing the treatment of the flue gas. As time goes by, after continuously filtering a large amount of flue gas, a large amount of dust particles will gradually accumulate on the surface of the filter plate 12, and the adsorption performance will also decrease, resulting in a reduction in filtration performance. At this time, the filter plate 12 needs to be replaced. The operator starts the motor 9, and the motor 9 rotates to drive the transmission column 10 connected to it. Multiple crescent-shaped limiting rings 11 are installed on the outer wall of the transmission column 10. Under the drive of the transmission column 10, the limiting rings 11 start to rotate. Since the filter plate 12 is firmly connected to the limiting rings 11, the filter plate 12 originally stored in the storage groove 4 is smoothly rotated out of the storage groove 4 under the drive of the limiting rings 11. During the rotation process, the filter plate 12 gradually approaches the working filter plate 12. As the transmission column 10 continues to rotate, the filter plate 12 accurately replaces the working filter plate 12, achieving a seamless connection. The original working filter plate 12 is rotated out of the storage groove 4 under the drive of the limiting rings 11. Thanks to the unique crescent-shaped design of the filter plate 12 and the limiting ring 11, as well as the special structure of the connecting groove 5, the filter plate 12 can smoothly enter the working position while the motor 9 drives the transmission column 10 to rotate, achieving seamless connection with the original filter plate 12. This ensures uninterrupted treatment of flue gas, which not only guarantees the continuous and stable operation of the stabilization furnace 1 and avoids flue gas emission problems caused by treatment interruption, but also greatly improves production efficiency, reduces the risk of environmental pollution, enhances environmental protection performance, and effectively achieves synergistic progress between production and environmental protection. The spring 17 in the annular groove 13 on the limiting ring 11 pushes the second baffle 16 with its own elasticity, so that the second baffle 16 pushes the limiting ring 11, making the limiting ring 11 tightly abut against the inner wall of the receiving groove 4, forming a good sealing effect. Whether the limiting ring 11 drives the filter plate 12 to rotate or the filter plate 12 is working normally, it can effectively prevent the flue gas from leaking from the receiving groove 4, ensuring that the entire treatment process is carried out in a relatively closed environment, improving the reliability of the equipment for flue gas treatment. The first baffle 14 can prevent the guide column 15 from being pulled out of the annular groove 13, and the third baffle 18 can prevent the second baffle 16 from being pulled out, thereby ensuring the normal operation of the guide column 15 and the spring 17.
