Description

Technical Field

[0001] This utility model relates to the field of discharge valve technology, specifically to a valve nozzle structure for packaging lining materials in a medium-frequency furnace. Background Art

[0002] The furnace lining material of the medium-frequency furnace is in powder form. After production, it needs to be discharged using a valve nozzle structure. Vertical discharge of the furnace lining material is the most common process. Generally, to save energy, the discharge of the furnace lining material in the direction of gravity relies on gravity to allow the material to fall freely. The discharge nozzle of the furnace lining material in the direction of gravity includes an upper feeding section and a lower feeding section. Although the outlet size of the feeding section is much larger than the particle size of the furnace lining material, bridging may still occur when the furnace lining material is discharged downward as a whole. This blockage will cause the discharge nozzle to malfunction, which in turn will affect the malfunction of the entire system. The main causes of blockage are friction between the furnace lining material and the inner wall of the nozzle, and friction between the furnace lining materials themselves.

[0003] To prevent blockage of the furnace lining material during the discharge process, a corresponding anti-blocking device must be installed in the discharge nozzle. Based on this, a valve nozzle structure for packaging medium-frequency furnace lining material is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the prior art by providing a valve nozzle structure for packaging lining materials in medium-frequency furnaces.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a valve nozzle structure for packaging lining materials for a medium-frequency furnace, including a nozzle pipe, a valve installed on the lower half of the nozzle pipe, a receiving hopper installed on the top side of the nozzle pipe, and a shaking component and a pulling component installed on the nozzle pipe in the upper half of the nozzle pipe.

[0006] The vibration assembly includes multiple sets of mounting plates installed on the nozzle pipe. A movable rod is slidably connected to the mounting plate. A vibration plate is installed on each set of movable rods. A spring is sleeved on the outer periphery of the movable rod. The spring is located between the mounting plate and the vibration plate. The pulling assembly is connected to the movable rod.

[0007] By adopting the above technical solution, the shaking component can shake the furnace lining material accumulated in the feed nozzle pipe, so that the accumulated furnace lining material can be broken up and fall smoothly from the feed nozzle pipe, avoiding the formation of bridging in the furnace lining material during the feeding process. The pulling component makes it convenient for the operator to drive the shaking component to shake from outside the feed nozzle pipe. The mounting plate can easily support and limit the moving rod. The up and down movement of the moving rod can drive the shaking plate to move up and down. The spring can drive the shaking plate to shake when the deformation is restored. When the shaking plate shakes, it can impact the furnace lining material in the feed nozzle pipe, thereby breaking up the accumulated furnace lining material.

[0008] Preferably, a scraper is installed on the side of the vibrating plate near the nozzle pipe, and the scraper is in contact with the nozzle pipe.

[0009] By adopting the above technical solution, the scraper can scrape off the furnace lining material on the side wall of the feed nozzle pipe, thereby cleaning the inner wall of the feed nozzle pipe.

[0010] Preferably, the longitudinal section of the vibrating plate is trapezoidal, and the side of the vibrating plate closer to the nozzle pipe is higher than the side of the vibrating plate farther from the nozzle pipe.

[0011] By adopting the above technical solution, the longitudinal section of the shaking plate is set into a trapezoidal shape, which can guide the furnace lining material to be fed. The furnace lining material can slide down along the inclined surface of the shaking plate, avoiding the accumulation of furnace lining material on the shaking plate.

[0012] Preferably, the feed nozzle pipe is a square pipe, and the receiving hopper is a frustum shape.

[0013] By adopting the above technical solution, the shape of the nozzle pipe is adapted to the shape of the rectangular frame and the combined connecting plate, which facilitates the installation of the rectangular frame and the connecting plate.

[0014] Preferably, the outer periphery of the spring is provided with a telescopic sleeve, which is installed between the mounting plate and the vibrating plate.

[0015] By adopting the above technical solution, the telescopic sleeve can prevent dust from entering the inside of the telescopic sleeve, thereby preventing dust from accumulating on the spring and causing the spring to be unable to be compressed.

[0016] Preferably, the pulling assembly includes a plurality of first pull ropes slidably connected to the nozzle pipe, a connecting plate is installed at one end of the first pull rope inside the nozzle pipe, the connecting plate is connected to the moving rod, a pull ring is installed at one end of the first pull rope outside the nozzle pipe, and a first through hole is provided on the nozzle pipe for the first pull rope to slide.

[0017] By adopting the above technical solution, the first pull rope can be moved by pulling the pull ring. The first pull rope can move the connecting plate, and the connecting plate can move the moving plate and the shaking plate, thereby causing the shaking plate to shake. The first through hole can conveniently set the first pull rope and the pull ring outside the feed nozzle pipe, thus making it convenient for the user to pull the pull ring.

[0018] Preferably, multiple sets of guide rings are installed on the side wall of the nozzle pipe, and the first pull rope is slidably connected in the corresponding set of guide rings.

[0019] By adopting the above technical solution, the guide ring can guide the first pull rope, so that the first pull rope is placed in the nozzle pipe in an orderly manner.

[0020] Preferably, the pulling assembly includes a second pull rope slidably connected to one side of the nozzle pipe. One end of the second pull rope located inside the nozzle pipe is equipped with multiple connecting ropes. A rectangular frame is installed at the end of the multiple connecting ropes away from the second pull rope. The rectangular frame is connected to the moving rod. A first through hole is provided on the nozzle pipe for the second pull rope to move.

[0021] By adopting the above technical solution, the second pull rope can drive multiple connecting ropes to move together at one time, and the multiple connecting ropes can drive the rectangular frame to move together, thereby facilitating the rectangular frame to drive the shaking component to work, without the need to pull each shaking plate individually.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] By installing a shaking component on the feed nozzle pipe, the moving rod and shaking plate can be driven to shake up and down when the spring deforms and recovers. During the downward movement of the shaking plate, the material accumulated on the shaking plate can lose support, so that the material falls out of the feed nozzle pipe under the action of gravity, thus avoiding the formation of bridging in the feed nozzle pipe.

[0024] By installing a pulling component on the feed nozzle pipe, the pulling ring can drive the moving rod and the shaking plate to move downwards, thereby compressing the spring on the shaking plate. The spring deforms and accumulates elastic potential energy, which facilitates the spring deformation recovery and drives the shaking plate to shake, shaking and cleaning the furnace lining material accumulated in the feed nozzle pipe. At the same time, the elastic force can move the shaking plate to a higher position relative to the initial position, so that the shaking plate can impact the furnace lining material accumulated above the shaking plate, so that the accumulated furnace lining material can be broken up and discharged from the feed nozzle pipe.

[0025] By installing a scraper on the vibrating plate, the vibrating plate can scrape the material on the inner wall of the nozzle pipe as it moves up and down, thereby scraping off the material adhering to the nozzle pipe. Attached Figure Description

[0035] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example 1

[0036] Please refer to Figures 1 to 8The valve nozzle structure for packaging lining material of medium frequency furnace in this embodiment includes a nozzle pipe 1, a valve 2 installed on the lower half of the nozzle pipe 1, a receiving hopper 3 installed on the top side of the nozzle pipe 1, a shaking component 400 and a pulling component 500 installed on the nozzle pipe 1 in the upper half of the nozzle pipe 1.

[0037] In this embodiment, valve 2 can be opened when it is necessary to discharge the furnace lining material, thereby facilitating the control of the furnace lining material discharge from the nozzle pipe 1. When discharge is not required, the nozzle pipe 1 can be closed to prevent the furnace lining material from leaking out. The receiving hopper 3 can expand the receiving range of the nozzle pipe 1, allowing the furnace lining material to smoothly enter the nozzle pipe 1, thereby preventing blockage in the nozzle pipe 1. The pulling component 500 can be pulled when it is necessary to clean the furnace lining material in the nozzle pipe 1, thereby driving the shaking component 400 to clean the furnace lining material. At the same time, it allows workers to easily pull the shaking component 400 from outside the feed nozzle pipe 1 without the need for manual use of other tools to shake the shaking component 400. The shaking component 400 can shake the furnace lining material accumulated in the feed nozzle pipe 1, so that the accumulated furnace lining material can be broken up, allowing the furnace lining material accumulated in the feed nozzle pipe 1 to fall smoothly from the feed nozzle pipe 1, thereby driving the shaking component 400 to shake. The shaking component 400 and the pulling component 500 are used together to prevent the furnace lining material from forming bridges during the feeding process.

[0038] It should be noted that when the furnace lining material enters the feed nozzle pipe 1 from the receiving hopper 3, the cross-sectional dimension of its flow will decrease, which will cause the furnace lining material to be squeezed against each other, resulting in the furnace lining material sticking together and forming bridging.

[0039] Please refer to Figures 1 to 5 In this embodiment, the feed nozzle pipe 1 is a square pipe, the receiving hopper 3 is a frustum shape, and the shaking component 400 includes multiple sets of mounting plates 401 installed on the feed nozzle pipe 1. A moving rod 402 is slidably connected to the mounting plate 401. A shaking plate 403 is installed on each set of moving rods 402. A spring 404 is sleeved on the outer periphery of the moving rod 402. The spring 404 is located between the mounting plate 401 and the shaking plate 403. The pulling component 500 is connected to the moving rod 402. A scraper 405 is installed on the side of the shaking plate 403 near the feed nozzle pipe 1. The scraper 405 is in contact with the feed nozzle pipe 1. The longitudinal section of the shaking plate 403 is trapezoidal. The side of the shaking plate 403 near the feed nozzle pipe 1 is higher than the side of the shaking plate 403 away from the feed nozzle pipe 1. A telescopic sleeve is provided on the outer periphery of the spring 404. The telescopic sleeve is installed between the mounting plate 401 and the shaking plate 403.

[0040] In this embodiment, the mounting plate 401 can limit the movement rod 402, ensuring that the movement rod 402 moves in a straight line during movement. When the movement rod 402 moves downward, it can drive the shaking plate 403 to move downward, thereby enabling the shaking plate 403 to compress the spring 404. When the spring 404 recovers its deformation, it can drive the shaking plate 403 to shake. When the spring 404 recovers its deformation, it can drive the shaking plate 403 to move to a higher position than the initial position, thereby impacting the furnace lining material in the feed nozzle pipe 1. After being impacted by the shaking plate 403, the furnace lining material will be broken up, so that the furnace lining material can smoothly leak out of the feed nozzle pipe 1, avoiding the formation of bridging by the furnace lining material and blocking the feed nozzle pipe 1.

[0041] It should be noted that the telescopic sleeve is used to prevent the furnace lining material from accumulating on the spring 404 and causing the spring 404 to be unable to be compressed. The longitudinal section of the shaking plate 403 is set in a trapezoidal shape to guide the furnace lining material to be discharged. After the furnace lining material falls onto the shaking plate 403, it can slide down the inclined surface of the shaking plate 403, thereby preventing the furnace lining material from accumulating on the shaking plate 403. The scraper 405 is used to scrape off the furnace lining material on the side wall of the nozzle pipe 1, thereby preventing the furnace lining material from sticking to the side wall of the nozzle pipe 1 and causing furnace lining material waste. At the same time, the furnace lining material on the side wall reduces the area through which the falling furnace lining material can pass.

[0042] The pulling assembly 500 includes a plurality of first pull ropes 501 slidably connected to the nozzle pipe 1. A connecting plate 502 is installed at one end of the first pull rope 501 inside the nozzle pipe 1. The connecting plate 502 is connected to the moving rod 402. A pull ring 503 is installed at one end of the first pull rope 501 outside the nozzle pipe 1. A first through hole is opened on the nozzle pipe 1 for the first pull rope 501 to slide. A plurality of guide rings 504 are installed on the side wall of the nozzle pipe 1. The first pull rope 501 is slidably connected in a corresponding set of guide rings 504.

[0043] In this embodiment, the first pull rope 501 can drive the corresponding connecting plate 502 to move, thus eliminating the need for other tools to move the connecting plate 502. The connecting plate 502 can drive the moving rod 402 to move, and the moving rod 402 can drive the shaking plate 403 to move downward, so that the shaking plate 403 can compress the spring 404, thereby allowing the spring 404 to accumulate elastic potential energy. This facilitates the spring 404 to drive the shaking plate 403 to shake when it recovers from deformation, and at the same time, it allows the shaking plate 403 to move to a higher height than its initial height under the action of elastic force. The position allows the furnace lining material piled above the shaking plate 403 to be impacted, causing it to loosen and fall off. The pull ring 503 facilitates the movement of the first pull rope 501 while preventing it from falling into the material nozzle pipe 1 through the first through hole. This would prevent the first pull rope 501 from being pulled from outside the material nozzle pipe 1. The diameter of the first through hole is slightly larger than that of the first pull rope 501, ensuring that the first pull rope 501 can be pulled while preventing a large amount of furnace lining material from flowing out of the first through hole.

[0044] It should be noted that a sliding sealing ring may be provided on the first through hole. The sliding sealing ring can seal the first through hole while ensuring that the first pull rope 501 can slide normally. Sealing the first through hole can prevent the furnace lining material from leaking out of the first through hole. The guide ring 504 can guide the first pull rope 501. When the first pull rope 501 is pulled, the first pull rope 501 can move along the guide ring 504, preventing multiple first pull ropes 501 from getting tangled in the material nozzle pipe 1.

[0045] Operating mode: When it is necessary to clean the furnace lining material accumulated in the feed nozzle pipe 1, pull the pull ring 503. The pull ring 503 drives the first pull rope 501 to move within the guide ring 504. The first pull rope 501 drives the connecting plate 502 to move downward together. The connecting plate 502 drives the moving rod 402 and the shaking plate 403 to move downward. Some of the furnace lining material falls because it loses the support of the shaking plate 403. The downward movement of the shaking plate 403 compresses the spring 404. At the same time, the shaking plate 403 drives the scraper. 405 scrapes off the material adhering to the inner wall of the feed nozzle pipe 1, then releases the pull ring 503. The shaking plate 403 shakes up and down under the action of the spring 404's deformation recovery. When the shaking plate 403 moves to a position higher than its initial position, it impacts the remaining furnace lining material accumulated in the feed nozzle pipe 1, causing the furnace lining material to fall off under the impact of external force. The pull rings 503 corresponding to other shaking plates 403 are pulled in sequence, so that the shaking plates 403 at different positions can shake. Example 2

[0046] Please refer to Figures 6 to 8In this embodiment, the pulling component 500 includes a second pull rope 505 slidably connected to one side of the nozzle pipe 1. Multiple connecting ropes 506 are installed at one end of the second pull rope 505 inside the nozzle pipe 1. A rectangular frame 507 is installed at the end of the multiple connecting ropes 506 away from the second pull rope 505. The rectangular frame 507 is connected to the moving rod 402. The end of the second pull rope 505 outside the nozzle pipe 1 is connected to the pull ring 503. A first through hole is provided on the nozzle pipe 1 for the second pull rope 505 to move.

[0047] In this embodiment, the second pull rope 505 can drive multiple connecting ropes 506 to move together, and the multiple connecting ropes 506 can drive the rectangular frame 507 to move together, so that the staff can pull multiple moving rods 402 and shaking plate 403 to move down at one time, thus eliminating the need to pull each moving rod 402 individually and improving the pulling efficiency.

[0048] It should be noted that because the rectangular frame 507 has an opening in the middle, the furnace lining material can pass through the opening of the rectangular frame 507, thus preventing the furnace lining material from accumulating on the rectangular frame 507 and being unable to fall off.

[0049] Operating mode: When it is necessary to clean the furnace lining material accumulated in the feed nozzle pipe 1, pull the pull ring 503. The pull ring 503 drives the second pull rope 505 to move. The second pull rope 505 drives multiple connecting ropes 506 to move downward together. The connecting ropes 506 drive the rectangular frame 507 to move downward together. The rectangular frame 507 drives the moving rod 402 and the shaking plate 403 to move downward. Some of the furnace lining material falls because it loses the support of the shaking plate 403. The downward movement of the shaking plate 403 compresses the spring 404, and at the same time, it shakes. Plate 403 drives scraper 405 to scrape off the material adhering to the inner wall of the feed nozzle pipe 1. Then, pull ring 503 is released, and vibrating plate 403 vibrates up and down under the action of spring 404 deformation recovery. When vibrating plate 403 moves to a position higher than the initial position of vibrating plate 403, vibrating plate 403 impacts the remaining furnace lining material accumulated in feed nozzle pipe 1, so that the furnace lining material can fall off under the impact of external force. The pull ring 503 corresponding to other vibrating plates 403 is pulled in turn, so that vibrating plates 403 at different positions can vibrate.

[0050] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
