Description

Technical Field

[0001] This utility model relates to the technical field of sintering plants, and in particular to a splash-proof sealing cover for a lime silo. Background Technology

[0002] The lime silo in a sintering plant is a key piece of equipment used to store lime in the sintering production process. As an important flux, lime has a significant impact on the quality and yield of sintered ore. Lime silos are usually closed tanks, mostly made of steel to ensure strength and sealing. They are equipped with a feed inlet at the top, and lime is injected by tank trucks through pneumatic conveying or other methods. They are also equipped with a bag filter on the top of the silo to filter the dust generated during transportation, reducing environmental pollution. They are also equipped with an explosion relief valve to prevent danger caused by abnormal pressure inside the silo. The silo is generally equipped with a material level monitoring device, which can provide real-time feedback on the lime storage level for production control. The discharge port at the bottom is connected to the feeding equipment to accurately control the amount of lime discharged and stably transport it to the subsequent sintering process.

[0003] However, the lime discharge port has a splashing problem, which leads to unorganized emissions, causing on-site environmental pollution and increasing the labor intensity of cleaning. In addition, the splashing makes it difficult to accurately measure the amount of material discharged during tray running, which can easily cause deviations in tray running data and affect the accuracy of production control. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of splashing at the lime discharge port in the existing technology, which leads to unorganized emissions, causes on-site environmental pollution, increases the labor intensity of cleaning, and makes it difficult to accurately measure the amount of material discharged during tray running, which can easily cause deviations in tray running data and affect the accuracy of production control. Therefore, a splash-proof sealing cover for lime silos is proposed.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a splash-proof sealing cover for a lime silo, comprising a frame, a discharge port, and a sealing device. The discharge port is located on the surface of the frame, and the sealing device is located on the lower surface of the frame. The sealing device includes a retainer fixedly connected to the frame. A pulley is rotatably connected to the surface of the retainer, and a rotating rod is fixedly connected to one end of the pulley. There are two pulleys, which are respectively located at both ends of the rotating rod. An adjustment hole is provided on the surface of the pulley. A baffle is fixedly connected to the surface of the rotating rod. The baffle is inclined and located on the lower surface of the discharge port. By setting the sealing device, the rocker arm can be rotated to adjust the inclination angle of the baffle, thereby narrowing the discharge port to achieve uniform material discharge, reducing lime splashing and fugitive emissions, reducing the labor intensity of the work, improving the on-site environment, and improving the accuracy of material measurement during tray operation. Furthermore, the baffle angle can be fixed by inserting a rod to ensure stable guidance of lime discharge.

[0006] Preferably, the surface of the card holder is provided with a threaded hole, and the inner wall of the threaded hole of the card holder is threaded with a plug rod. The plug rod is inserted into the adjustment hole. By setting the plug rod, after the baffle is adjusted to a suitable tilt angle, it is inserted into the adjustment hole through thread engagement to fix the position of the baffle. This prevents the baffle from shifting in angle due to material impact or vibration during the lime feeding process, ensuring that the baffle can stably shrink the discharge port and guide the lime to be fed evenly, thereby maintaining the effects of reducing splashing and ensuring accurate metering of the running tray, and ensuring the stable working state of the sealing device.

[0007] Preferably, there are two baffles arranged symmetrically. One end of the pulley is fixedly connected to a rocker arm. By setting the baffles, the tilt angle is adjusted to shrink the discharge port, guiding the lime to achieve normal and uniform feeding, reducing the unorganized emissions caused by splashing, reducing the labor intensity of the cleaning work, and improving the on-site environment. At the same time, by stably guiding the lime, the accuracy of the feeding amount measurement is improved when the tray is running, and the angle can be kept stable after the rod is fixed, ensuring that the above-mentioned functions are continuously and effectively performed, and maintaining the smoothness and controllability of the feeding process.

[0008] Preferably, the surface of the baffle is provided with a scraping component, which includes a scraper. The scraper is slidably connected to the baffle, and a traction rope is fixedly connected to one end of the scraper. A wheel is rotatably connected to one end of the baffle, and the traction rope contacts the wheel. By setting up the scraping component, the motor drives the scraper to move, which can promptly scrape off the lime adhering to the surface of the baffle, reduce solidification and blockage. When the motor rotates in the reverse direction, the spring can pull the scraper to reset, ensuring a continuous and effective cleaning effect and maintaining smooth material feeding.

[0009] Preferably, a motor is fixedly connected to the lower surface of the baffle, and the end of the traction rope away from the scraper is fixedly connected to the drive end of the motor. By setting the motor, the traction rope is driven to wind up or release. Winding up the traction rope pulls the scraper to move, causing the scraper to scrape off the lime adhering to the surface of the baffle, reducing solidification and blockage. When the motor rotates in the reverse direction, the traction rope is released, and the scraper is reset in conjunction with the spring force, ensuring that the scraper can continuously clean the surface of the baffle, maintain smooth material feeding, and ensure the stable operation of the sealing device.

[0010] Preferably, the surface of the scraper is chamfered, and the scraper is trapezoidal in shape.

[0011] Preferably, a spring is fixedly connected to one end of the scraper, and the end of the spring away from the scraper is fixedly connected to the baffle. By setting the spring, when the motor rotates in the reverse direction and the traction rope is loosened, the scraper is pulled back to its initial position by its own elasticity. This allows the scraper to scrape the baffle surface again when the motor is driven next time, ensuring that the scraping component can continuously clean the white dust adhering to the baffle and avoid the scraper failing to reset, which would affect the subsequent cleaning effect and maintain the smooth flow of the material discharge channel.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, a sealing device is installed. During use, rotating the rocker arm drives the pulley to rotate, which in turn drives the rotating rod to rotate. The rotating rod causes the baffle to tilt. The tilt angle of the baffle can be adjusted according to actual usage. The baffle retracts the discharge port, allowing for normal and uniform material discharge, reducing splashing and unorganized emissions, reducing labor intensity, and improving the working environment. It also allows for more accurate control of the material discharge during tray operation. Once the angle is at the appropriate position, rotating the insert rod, with the help of the thread, inserts the rod into the adjustment hole to fix the baffle. Subsequently, it guides the lime during discharge. By installing the sealing device, the rocker arm can be rotated to adjust the tilt angle of the baffle, retracting the discharge port to achieve uniform material discharge, reducing lime splashing and unorganized emissions, lowering labor intensity, improving the working environment, and improving the accuracy of material measurement during tray operation. Furthermore, the insert rod can fix the baffle angle to ensure stable guidance of lime discharge.

[0013] In this invention, by setting up a scraping component, during operation, the motor is started, and the motor drives the traction rope to wind up. As the traction rope winds up, it pulls the scraper, which moves and scrapes off and loosens the white ash adhering to the baffle surface, reducing the possibility of solidification and clumping. When the motor rotates in the reverse direction, the spring is released and generates elastic force to pull the scraper back to its original position. By setting up the scraping component, the motor-driven scraper can promptly scrape off the white ash adhering to the baffle surface, reducing solidification and clumping, and reducing blockage. When the motor rotates in the reverse direction, the spring can pull the scraper back to its original position, ensuring a continuous and effective cleaning effect and maintaining smooth material feeding.

[0016] Please see Figures 1-5 This utility model provides a technical solution: a splash-proof sealing cover for a ash silo, including a frame 1, a discharge port 2 and a sealing device 3. The discharge port 2 is opened on the surface of the frame 1, and the sealing device 3 is set on the lower surface of the frame 1.

[0017] In this embodiment: the sealing device 3 includes a retainer 32, which is fixedly connected to the frame 1. A pulley 36 is rotatably connected to the surface of the retainer 32. A rotating rod 37 is fixedly connected to one end of the pulley 36. There are two pulleys 36, which are respectively set at both ends of the rotating rod 37. An adjustment hole 38 is opened on the surface of the pulley 36. A baffle 31 is fixedly connected to the surface of the rotating rod 37. The baffle 31 is inclined and located on the lower surface of the discharge port 2. By setting the sealing device 3, the rocker arm 34 can be rotated to adjust the inclination angle of the baffle 31, thereby shrinking the discharge port 2 to achieve uniform material feeding, reduce lime splashing and fugitive emissions, reduce the labor intensity of the work, improve the on-site environment, and improve the accuracy of material feeding measurement during tray running. The angle of the baffle 31 can be fixed by the insertion rod 33 to ensure stable guidance of lime feeding.

[0018] Specifically, the surface of the card holder 32 is provided with a threaded hole, and the inner wall of the threaded hole of the card holder 32 is threaded with a rod 33. The rod 33 is inserted into the adjustment hole 38. By setting the rod 33, after the baffle 31 is adjusted to a suitable tilt angle, it is inserted into the adjustment hole 38 through thread engagement to fix the position of the baffle 31. This prevents the baffle 31 from shifting its angle due to material impact or vibration during the lime feeding process, ensuring that the baffle 31 can stably shrink the discharge port 2 and guide the lime to be fed evenly, thereby maintaining the effects of reducing splashing and ensuring accurate metering of the running tray, and ensuring the stable working state of the sealing device 3.

[0019] Specifically, there are two baffles 31, which are symmetrically arranged. One end of the pulley 36 is fixedly connected to a rocker arm 34. By setting the baffles 31, the tilt angle is adjusted to shrink the discharge port 2, guiding the lime to achieve normal and uniform feeding, reducing the unorganized emissions caused by splashing, reducing the labor intensity of the cleaning work, and improving the on-site environment. At the same time, by stably guiding the lime, the accuracy of the feeding amount measurement is improved when the tray is running, and the angle can be kept stable after the insertion rod 33 is fixed, ensuring that the above functions are continuously and effectively performed, and maintaining the smoothness and controllability of the feeding process.

[0020] Specifically, a scraping assembly 35 is provided on the surface of the baffle 31. The scraping assembly 35 includes a scraper 351, which is slidably connected to the baffle 31. A traction rope 353 is fixedly connected to one end of the scraper 351, and a wheel 352 is rotatably connected to one end of the baffle 31. The traction rope 353 contacts the wheel 352. By setting the scraping assembly 35, the motor 355 drives the scraper 351 to move, which can scrape off the white lime adhering to the surface of the baffle 31 in time, reduce solidification and blockage. When the motor 355 rotates in the reverse direction, the spring 354 can pull the scraper 351 to reset, ensuring a continuous and effective cleaning effect and maintaining smooth material feeding.

[0021] Specifically, a motor 355 is fixedly connected to the lower surface of the baffle 31, and the end of the traction rope 353 away from the scraper 351 is fixedly connected to the drive end of the motor 355.

[0022] In this embodiment: by setting a motor 355, the traction rope 353 is driven to wind up or release. By winding up the traction rope 353, the scraper 351 is moved, so that the scraper 351 scrapes off the white lime adhering to the surface of the baffle 31, reducing solidification and blockage. When the motor 355 rotates in the opposite direction, the traction rope 353 is released, and the scraper 351 is reset in conjunction with the elastic force of the spring 354, ensuring that the scraper 351 can continuously clean the surface of the baffle 31, maintain smooth material feeding, and ensure the stable operation of the sealing device 3.

[0023] Specifically, the scraper 351 has a chamfer on its surface and is arranged in a trapezoidal shape.

[0024] Specifically, a spring 354 is fixedly connected to one end of the scraper 351, and the end of the spring 354 away from the scraper 351 is fixedly connected to the baffle 31.

[0025] In this embodiment: by setting a spring 354, when the motor 355 rotates in the reverse direction and the traction rope 353 is relaxed, the scraper 351 is pulled back to its initial position by its own elasticity, so that the scraper 351 can be scraped again on the surface of the baffle 31 when the motor 355 is driven next time. This ensures that the scraping component 35 can continuously clean the white dust adhering to the baffle 31, and avoids the scraper 351 from affecting the subsequent cleaning effect due to its inability to reset, thus maintaining the smooth flow of the material feeding channel.

[0026] Working principle: By setting up the sealing device 3, during use, rotating the rocker arm 34 causes the pulley 36 to rotate, which in turn drives the rotating rod 37 to rotate. The rotating rod 37 tilts the baffle 31. The tilt angle of the baffle 31 can be adjusted according to actual use. After the baffle 31 retracts the discharge port 2, the material is discharged normally and evenly, reducing splashing and unorganized emissions, reducing the labor intensity of the workers, and improving the on-site environment. It also allows for more accurate control of the material discharge amount when the tray is in operation. When the angle is at its lowest... After reaching the appropriate position, rotate the insert rod 33. With the engagement of the thread, the insert rod 33 is inserted into the adjustment hole 38 to fix the baffle 31. Then, during material feeding, it guides the lime. By setting the sealing device 3, the rocker arm 34 can be rotated to adjust the tilt angle of the baffle 31, shrink the discharge port 2 to achieve uniform material feeding, reduce lime splashing and fugitive emissions, reduce the labor intensity of the work, improve the on-site environment, and at the same time improve the accuracy of material feeding measurement during tray running. The angle of the baffle 31 can be fixed by the insert rod 33 to ensure stable guidance of lime feeding. By setting up the scraping component 35, during operation, the motor 355 is started, and the motor 355 drives the traction rope 353 to wind up. While the traction rope 353 is winding up, it pulls the scraper 351. The scraper 351 moves and scrapes off and loosens the white ash adhering to the surface of the baffle 31, reducing the possibility of solidification and clumping. When the motor 355 rotates in the reverse direction, the spring 354 loses its restraint and generates elastic force to pull the scraper 351 back to its original position. By setting up the scraping component 35, the motor 355 drives the scraper 351 to move, which can promptly scrape off the white ash adhering to the surface of the baffle 31, reducing solidification and clumping and reducing blockage. When the motor 355 rotates in the reverse direction, the spring 354 can pull the scraper 351 back to its original position, ensuring a continuous and effective cleaning effect and maintaining smooth material feeding.
