Description

Technical Field

[0001] This application relates to the field of metallurgical material conveying and control, and in particular to a quick-opening discharge valve for a metallurgical reactor. Background Technology

[0002] In the metallurgical industry's production process, metallurgical reactors play a crucial role, and the discharge valve, as a key component of the reactor, directly impacts the efficiency and stability of the entire production process. With the continuous development of the metallurgical industry, the demands for production efficiency and product quality are increasing, making efficient, stable, and durable discharge valves particularly important. They not only precisely control material discharge, ensuring the smooth progress of metallurgical reactions, but also play a crucial connecting role in subsequent product processing stages, thus having significant implications for the overall development of the metallurgical industry.

[0003] In previous technologies, various methods were typically employed to control and clean the discharge valve of a reactor. The valve was usually driven by an electric or pneumatic cylinder connected to the valve stem, enabling rapid connection and control, and conveniently opening and closing the valve to meet certain production needs. However, there was no perfect solution for cleaning the valve's inner wall; most methods relied solely on the flow of material to reduce residue, lacking an active cleaning mechanism. Some solutions attempted simple rinsing, but the results were unsatisfactory. While these methods allowed for some operation and basic cleaning of the discharge valve, they failed to effectively address the problem of easily adhering substances to the valve's inner wall.

[0004] The aforementioned technologies, which rely solely on the material's own flow to reduce residue on the valve body's inner wall, cannot effectively remove material adhering to the inner wall. This is because, during operation, some components of the material adhere firmly to the valve body's inner wall due to chemical reactions, temperature changes, and other factors, forming difficult-to-remove residues. Long-term accumulation causes these residues to thicken, severely affecting the valve's normal operation. This can lead to problems such as difficulty in opening and closing the valve, decreased sealing performance, and shortened valve lifespan, failing to meet the requirements of efficient and stable operation of discharge valves in metallurgical production. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a quick-opening discharge valve for metallurgical reactors.

[0006] The quick-opening discharge valve for a metallurgical reactor provided in this application adopts the following technical solution:

[0007] A quick-opening discharge valve for a metallurgical reactor includes a valve body. The valve body includes a first flow channel for material flow and a second flow channel connected to the first flow channel. A piston for blocking the first flow channel slides within the second flow channel. A first driving member for driving the piston to slide is provided at the end of the second flow channel. A groove is formed in the inner wall of the first flow channel. A sealing plate with the same curvature as the inner wall of the first flow channel is embedded in the groove. An elastic scraper for scraping off the deposits in the first flow channel is provided on the side of the sealing plate facing the groove. Annular cavities are formed at both ends of the first flow channel. A rotating support assembly for driving the elastic scraper to rotate against the inner wall of the first flow channel is provided in the annular cavity.

[0008] By adopting the above technical solution, during the discharge process of the metallurgical reactor, and when it is necessary to clean the deposits on the inner wall of the first flow channel, the first driving component drives the piston to slide in the second flow channel to control the opening and closing of the first flow channel. At this time, the sealing plate is pulled out of the groove by the actuating component, and the elastic scraper on the sealing plate is exposed. The second driving component is activated, causing the gear ring in the rotating support assembly to rotate. Since the connecting rod and the gear ring are connected to the first elastic component through the connecting pipe, the rotation of the gear ring drives the connecting rod, which in turn drives the elastic scraper to rotate against the inner wall of the first flow channel. During the rotation, the elastic scraper scrapes off the deposits on the inner wall of the first flow channel, reducing the material residue on the inner wall of the valve body. This design not only achieves effective cleaning of the inner wall of the first flow channel, but also avoids corrosion and damage to the valve body caused by material residue, extending the service life of the discharge valve. Moreover, the quick connection between the electric push cylinder and the valve stem enables rapid response to discharge and cleaning operations, improving the production efficiency of the metallurgical reactor.

[0009] Preferably, the rotary support assembly includes a gear ring that rotates coaxially within the annular cavity, a connecting tube fixed to the side wall of the gear ring, a first elastic element disposed within the connecting tube, and a connecting rod fixed to the side of the sealing plate facing the gear ring. The connecting rod slides within the connecting tube. The first elastic element is used to drive the connecting rod to reset. One end of the first flow channel is provided with a toggle element to facilitate the extension of the sealing plate out of the groove. Another end of the first flow channel is provided with a second driving element for driving the gear ring to rotate.

[0010] By adopting the above technical solution, when it is necessary to clean the deposits on the inner wall of the first flow channel, the actuating component is operated to push the fixed rod, thereby causing the connecting rod and the sealing plate to extend out of the groove. At this time, the elastic scraper on the sealing plate is in contact with the inner wall of the first flow channel. Next, the second driving component is activated to rotate the gear, which drives the meshing gear ring to rotate in the annular cavity. When the gear ring rotates, it drives the connecting rod and the sealing plate to rotate circumferentially along the inner wall of the first flow channel through the connecting pipe, thereby causing the elastic scraper to scrape the inner wall of the first flow channel. During the scraping process, the first elastic component can ensure the stable sliding and resetting of the connecting rod in the connecting pipe, ensuring that the elastic scraper is always in good contact with the inner wall of the first flow channel. This dynamic scraping method can effectively reduce the material residue on the inner wall of the first flow channel. Compared with the traditional discharge valve, it can better maintain the cleanliness of the inner wall of the flow channel, extend the service life of the discharge valve, and improve the stability and efficiency of the discharge process of the metallurgical reactor.

[0011] Preferably, the actuating component includes a mounting block fixed to the end face of the valve body, a guide cavity formed on the mounting block, a push rod sliding in the guide cavity, and a fixing rod fixed to the side wall of the connecting rod. The end of the first flow channel is provided with a positioning groove communicating with the annular cavity, and the fixing rod is initially located in the positioning groove.

[0012] By adopting the above technical solution, when it is necessary to clean the deposits on the inner wall of the first flow channel, the push rod sliding in the guide cavity is pushed. Since the end of the push rod near the fixed rod is arc-shaped and the fixed rod is a round rod, the push rod can smoothly contact and push the fixed rod when it moves. In the initial state, the fixed rod is located in the positioning groove. As the push rod pushes the fixed rod, the fixed rod drives the connecting rod, so that the sealing plate connected to the connecting rod gradually extends out of the groove. The sealing plate is provided with an elastic scraper for scraping off the deposits in the first flow channel. After the sealing plate extends, the elastic scraper contacts the inner wall of the first flow channel. Then, the second driving component drives the gear ring to rotate. The rotation of the gear ring drives the connecting tube to rotate. The connecting tube is connected to the connecting rod through the first elastic component, thereby driving the connecting rod to rotate. This causes the sealing plate and the elastic scraper to rotate along the inner wall of the first flow channel, thereby scraping off the deposits on the inner wall of the first flow channel. This design effectively reduces material residue on the inner wall of the first flow channel, avoiding corrosion or blockage of the valve body caused by residual material, extending the service life of the discharge valve, and improving the stability and efficiency of material discharge from the metallurgical reactor.

[0013] Preferably, the end of the push rod near the fixed rod is arc-shaped, and the fixed rod is a round rod.

[0014] By adopting the above technical solution, when cleaning the deposits on the inner wall of the first flow channel, the operator pushes the push rod. Since the end of the push rod near the fixed rod is arc-shaped, and the fixed rod is round, the arc-shaped end of the push rod smoothly contacts and moves the round rod during the pushing process, causing the round rod to drive the connecting rod and the sealing plate out of the groove. At this time, a prism-shaped wrench is inserted into the prism sleeve, and rotating the prism sleeve causes the gear to rotate, meshing with the gear ring. The rotation of the gear ring then drives the elastic scraper to scrape the deposits on the inner wall. This design of the arc-shaped push rod and the round rod allows for a more efficient and smooth extension of the sealing plate, ensuring that the elastic scraper smoothly adheres to the inner wall of the first flow channel and rotates to scrape away the deposits, reducing residue on the inner wall of the valve body and effectively extending the service life of the discharge valve.

[0015] Preferably, the second driving component includes a gear rotatably connected in the annular cavity, a connecting shaft coaxially fixed on the gear, and a prism sleeve coaxially fixed on the connecting shaft. An installation groove is provided on the outer side wall of the first flow channel end. One end of the connecting shaft is located in the annular cavity, and the other end is located in the installation groove. The prism sleeve is rotatably connected in the installation groove.

[0016] By adopting the above technical solution, a prism wrench is inserted into the prism sleeve. Rotating the prism sleeve causes the connecting shaft to rotate, which in turn drives the gear to rotate. The gear meshes with the gear ring in the annular cavity, thereby driving the gear ring to rotate. The gear ring drives the connecting pipe to rotate, and the connecting pipe, through the connecting rod, drives the sealing plate and the elastic scraper to rotate against the inner wall of the first flow channel, thus scraping off the material adhering to the inner wall of the first flow channel. This reduces the material residue on the inner wall of the first flow channel and effectively extends the service life of the discharge valve.

[0017] Preferably, an annular plate is rotatably disposed inside the annular cavity, and a notch for embedding a sealing plate is provided on the annular plate. In the initial state, the sealing plate is embedded in the notch to block the annular cavity and groove of the valve body.

[0018] By adopting the above technical solution, in the initial state, the sealing plate is embedded in the notch of the annular plate, sealing the annular cavity and groove on the inner wall of the valve body, preventing material from entering the annular cavity and groove and causing material residue. When it is necessary to clean the inner wall of the first flow channel, the actuating component is operated to make the sealing plate extend out of the groove. The sealing plate drives the elastic scraper to adhere to the inner wall of the first flow channel. At this time, the second driving component drives the gear ring to rotate. The gear ring drives the sealing plate and the elastic scraper to rotate through the connecting pipe and connecting rod. The annular plate also rotates in the annular cavity. During the rotation, the elastic scraper scrapes off the adhering material on the inner wall of the first flow channel, reducing material residue on the inner wall of the valve body, reducing material corrosion and wear on the valve body, thereby extending the service life of the valve body.

[0019] Preferably, the elastic scraper is a spring, which is bent along the inner cavity of the first flow channel and is hooked between two connecting rods.

[0020] By adopting the above technical solution, when it is necessary to clean the deposits on the inner wall of the first flow channel, the push rod is moved, causing the round rod to drive the connecting rod and the sealing plate to extend out of the groove. At this time, the spring, acting as an elastic scraper, is in a working state. Then, a prism wrench is inserted into the prism sleeve, and rotating the prism sleeve drives the connecting shaft and gear to rotate. The gear meshes with the gear ring, causing the gear ring to rotate within the annular cavity. Since the spring is connected between the two connecting rods, the rotation of the gear ring will cause the connecting rod and the spring to rotate against the inner wall of the first flow channel, scraping off the deposits on the inner wall of the first flow channel. This dynamic scraping method can effectively reduce the material residue on the inner wall of the valve body, avoid long-term material adhesion causing corrosion and damage to the valve body, and thus extend the service life of the discharge valve.

[0021] Preferably, the first driving component includes a support base fixed to the end of the second flow channel and an electric actuator fixed to the support base, wherein the piston rod of the electric actuator is coaxially connected to the valve rod of the valve body.

[0022] By adopting the above technical solution, the electric cylinder and valve stem can be quickly connected, which improves the installation efficiency and can also better drive the piston to slide, so as to achieve the blocking and opening operation of the first flow channel.

[0023] Preferably, the inner edge of the end of the first flow channel connected to the reactor is chamfered.

[0024] By adopting the above technical solution, the material flows more smoothly from the reactor into the first flow channel, reducing the accumulation of material at the inlet of the first flow channel.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The electric actuator is connected to the valve stem, enabling quick connection and control of the valve, and allowing for convenient opening and closing of the valve;

[0027] 2. An elastic scraper is provided on the inner wall of the first flow channel. By rotating the support assembly, it is made to rotate against the inner wall to actively scrape off the deposits in the first flow channel and reduce the residue on the inner wall of the valve body.

[0028] 3. Reducing residue on the inner wall of the valve body can prevent residue buildup from affecting the normal use of the valve, ensure smooth valve opening and closing and sealing performance, and extend the service life of the valve. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0041] This application discloses a quick-opening discharge valve for a metallurgical reactor.

[0042] Reference Figures 1-3 A quick-opening discharge valve for a metallurgical reactor includes a valve body 1, a piston 4, a first driving component 5, a sealing plate 7, an elastic scraper 8, and a rotating support assembly 10. The valve body 1 includes a first flow channel 2 and a second flow channel 3. The valve body 1 is made of high-strength metal material and can withstand the pressure and wear of the material.

[0043] Reference Figure 2 Specifically, the first flow channel 2 and the second flow channel 3 are connected to each other to provide sliding space for the piston 4. The inner diameter of the first flow channel 2 is the same as that of the second flow channel 3. The second flow channel 3 and one end of the first flow channel 2 are coaxially arranged. The first flow channel 2 is used to flow materials. The first flow channel 2 is bent and the bending angle of the first flow channel 2 is 132 degrees.

[0044] Reference Figure 2 The piston 4 slides within the second flow channel 3 to block the first flow channel 2. When the first flow channel 2 is in a flowing state, the piston 4 slides from the first flow channel 2 into the inner cavity of the second flow channel 3. When the first flow channel 2 is blocked, the piston 4 slides out of the second flow channel 3 and into the inner cavity of the first flow channel 2 near the reactor, thereby cutting off the connection between the reactor and the first flow channel 2. The piston 4 is cylindrical and its shape is adapted to the shapes of the second flow channel 3 and the inner cavity of the first flow channel 2. A sealing ring is provided between the piston 4 and the second flow channel 3. When the piston 4 slides within the second flow channel 3, the sealing ring prevents material leakage.

[0045] Reference Figure 1 and Figure 2 The first driving component 5 is located at the end of the second flow channel 3 to drive the piston 4 to slide. The first driving component 5 includes a support base 28 and an electric actuator 29. The support base 28 is fixed to the end of the second flow channel 3, and the electric actuator 29 is fixed to the support base 28. The piston rod of the electric actuator 29 is coaxially connected to the valve rod of the valve body 1. When the electric actuator 29 is working, the extension and retraction of the piston rod can drive the piston 4 to slide precisely within the second flow channel 3, thereby controlling the opening and closing of the first flow channel 2. The electric actuator 29 can also be replaced by a pneumatic cylinder, which can also achieve the function of driving the piston 4 to slide.

[0046] Reference Figure 3 and Figure 4 To ensure the stability of material flow, a groove 6 is provided on the inner wall of the first flow channel 2 for embedding a sealing plate 7. When the sealing plate 7 is embedded in the groove 6, the curvature of the sealing plate 7 is the same as the curvature of the inner wall of the first flow channel 2, forming a continuous surface with the inner wall of the first flow channel 2, ensuring smooth material flow. To further ensure the stability of material flow, a chamfer is provided on the inner edge of the end of the first flow channel 2 connected to the reactor, allowing material to flow more smoothly from the reactor into the first flow channel 2.

[0047] Reference Figure 3 and Figure 4Both ends of the first flow channel 2 are provided with annular cavities 9. A rotating support assembly 10 is disposed within the annular cavity 9. An elastic scraper 8 is disposed on the side of the sealing plate 7 facing the groove 6. The rotating support assembly 10 is used to drive the elastic scraper 8 to rotate against the inner wall of the first flow channel 2, achieving precise control of material discharge and effective cleaning of deposits on the inner wall of the first flow channel 2. The elastic scraper 8 can scrape and clean the inner wall of the first flow channel 2 under the drive of the rotating support assembly 10.

[0048] Reference Figures 4-6 In this embodiment, the rotating support assembly 10 includes a gear ring 11, a connecting tube 12, a first elastic element 13, and a connecting rod 14. The gear ring 11 rotates coaxially within the annular cavity 9, and its sidewalls are provided with meshing teeth. To ensure that the elastic scraper 8 stably scrapes the inner wall of the first flow channel 2, the connecting tube 12 is fixed to the sidewall of the gear ring 11, providing sliding space for the connecting rod 14. The first elastic element 13 is disposed within the connecting tube 12 and is used to drive the connecting rod 14 to reset. When the sealing plate 7 is pushed out of the slot 6, the first elastic element 13 can cause the connecting rod 14 to drive the sealing plate 7 back to its initial position when needed. The first elastic element 13 can be a spring or other elastic element. The connecting rod 14 is fixed to the side of the sealing plate 7 facing the gear ring 11 and slides within the connecting tube 12.

[0049] Reference Figures 7-9 A second driving component 16 is provided at the end of the first flow channel 2 away from the reactor, and a gear ring 11 is used to cooperate with the second driving component 16. In this embodiment, the second driving component 16 includes a gear 22 rotatably connected in the annular cavity 9, a connecting shaft 23 coaxially fixed on the gear 22, and a prism sleeve 24 coaxially fixed on the connecting shaft 23. A mounting groove 25 is provided on the outer wall of the end of the first flow channel 2. One end of the connecting shaft 23 is located in the annular cavity 9, and the other end is located in the mounting groove 25. The prism sleeve 24 is rotatably connected in the mounting groove 25. At this time, a prism wrench is inserted into the prism sleeve 24, and the prism sleeve 24 is rotated, thereby causing the gear 22 to rotate, meshing with the gear ring 11. The gear ring 11 rotates, thereby driving the elastic scraper 8 to scrape against the inner wall of the first flow channel 2.

[0050] Reference Figures 4-6 In this embodiment, the elastic scraper 8 is preferably a spring, which can be bent along the inner cavity of the first flow channel 2. The elastic scraper 8 is hooked between the two connecting rods 14. When the toothed ring 11 drives the sealing plate 7 to rotate, the spring will scrape against the inner wall of the first flow channel 2 as the sealing plate 7 rotates. The elastic scraper 8 can also be replaced by a scraper made of elastic material such as a rubber scraper. These elastic scrapers can effectively scrape off the deposits on the inner wall of the first flow channel 2 when rotating.

[0051] Reference Figures 8-10To facilitate the stable operation of the elastic scraper 8, a toggle element 15 is provided at the end of the first flow channel 2 away from the reactor, which facilitates the movement of the sealing plate 7 out of the groove 6. The toggle element 15 includes a mounting block 17 fixed to the end face of the valve body 1, a guide cavity 18 formed on the mounting block 17, a push rod 19 sliding in the guide cavity 18, and a fixing rod 20 fixed to the side wall of the connecting rod 14. A positioning groove 21 communicating with the annular cavity 9 is formed on the end face of the first flow channel 2. In the initial state, the fixing rod 20 is located in the positioning groove 21. The end of the push rod 19 near the fixing rod 20 is arc-shaped, and the fixing rod 20 is a round rod. When it is necessary to clean the inner wall of the first flow channel 2, the push rod 19 is toggleed, and the arc end of the push rod 19 pushes the round rod, causing the round rod to drive the connecting rod 14 and the sealing plate 7 out of the groove 6.

[0052] Reference Figures 8-10 To ensure the sealing of material flow and the stability of the rotation of the gear ring 11, an annular plate 26, coaxial with the inner diameter of the first flow channel 2, is rotatably installed inside the annular cavity 9. A notch 27 for embedding the sealing plate 7 is provided on the annular plate 26. Initially, the sealing plate 7 is embedded in the notch 27, sealing the annular cavity 9 and the groove 6 on the inner wall of the valve body 1, preventing material from entering the annular cavity 9 and ensuring the normal operation of the valve body 1. When the sealing plate 7 rotates, it synchronously drives the annular plate 26 to rotate within the annular cavity 9, thereby achieving the effect of sealing the annular cavity 9 while cleaning the inner wall of the first flow channel 2.

[0053] The implementation principle of a quick-opening discharge valve for a metallurgical reactor according to this application embodiment is as follows: The quick-opening discharge valve uses an electric push cylinder 29 or a pneumatic cylinder, etc., as a first driving component 5 to drive a piston 4 to slide within the second flow channel 3, thereby opening and closing the first flow channel 2 and precisely controlling the discharge of materials. When it is necessary to clean the inner wall of the first flow channel 2, the actuating component 15 causes the sealing plate 7 to extend out of the groove 6, and then a prism-shaped wrench inserted into the prism sleeve 24 drives the toothed ring 11 to rotate, thereby causing the elastic scraper 8 to rotate against the inner wall of the first flow channel 2, scraping away the deposits on the inner wall. This structural design effectively solves the problem of difficult cleaning of the inner wall of the discharge valve in the prior art, improving the service life and operational stability of the discharge valve.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
