Description

Technical Field

[0001] The invention relates to the technical field of dry quenching coke sealing equipment, and in particular to a dry quenching furnace coke sealing device and a use method thereof. Background Art

[0002] Coke dry quenching uses a nitrogen-based mixed gas in the dry quenching furnace to cool the red coke pushed out of the coke oven. The coke can filled with red coke is lifted by a hoist, and then the coke can is moved horizontally above the dry quenching furnace mouth. The loading hopper is then pulled to the furnace mouth by an electric cylinder. The hoist drops the coke can onto the loading hopper of the dry quenching furnace mouth loading device. The bottom gate of the coke can is opened, and the red coke is loaded into the dry quenching furnace through the loading hopper.

[0003] After the red coke is loaded into the CDQ furnace, a large amount of high-temperature and high-pressure gas will be generated due to the high-temperature red coke, and these gases will continue to rise and push the furnace cover, causing slight friction between the furnace cover and the top of the CDQ furnace. In addition, every time the cover is opened, the furnace cover will rub against the top of the CDQ furnace. After long-term use, the edge of the furnace cover may be worn, which will affect the sealing and firmness of the furnace cover to the CDQ furnace. In response to the above problems, the following solutions are proposed. Summary of the invention

A pressure plate is provided by utilizing the fact that the high-temperature gas inside the dry quenching furnace is accompanied by high pressure and keeps rising. When the high-temperature and high-pressure gas in the dry quenching furnace continues to rise, the high-temperature and high-pressure gas will push the pressure plate upward to move upward, so that the pressure plate squeezes the hydraulic oil on the top thereof, allowing the hydraulic oil to enter the sealing plate through the connecting groove 1. In the sealing block, the sealing block is pushed to move outward to make it close to the inner surface of the dry quenching furnace mouth. When the hydraulic oil pushes the sealing block to move, the hydraulic oil will also push the sealing plate to move outward through the connecting hole to avoid the sealing blocks gradually separating from each other when the sealing blocks gradually extend outward, resulting in a larger gap and affecting the sealing of the furnace top. When the sealing plate is gradually extended, it will also move outward with the sealing block and close to the furnace mouth of the dry quenching furnace to enhance the sealing at the furnace mouth. Through the operation of the above components, the sealing and firmness of the furnace cover and the dry quenching furnace mouth can be improved, and it is avoided that the edge of the furnace cover is loosened when the high-temperature and high-pressure gas is continuously pushed upward, thereby affecting its sealing.

When the chain pulls the sliding block up, it will synchronously drive the piston rod 1 to rise, so that the piston rod 1 squeezes the water on its top, so that it pushes the telescopic rod outward through the connecting groove 2, so that the sealing block and the sealing plate that were originally close to the dry quenching furnace mouth are no longer close, and it is avoided that the sealing block and the sealing plate are too close to the dry quenching furnace mouth under the continuous push of the high-temperature and high-pressure gas inside the dry quenching furnace, thereby increasing the pulling force when pulling the furnace cover, increasing the working load of the electric telescopic rod and reducing its service life. When the pulling force is too large, it may cause greater wear of the sealing block, the sealing plate and the chain, which will affect the normal operation of the equipment and the sealing of the top of the dry quenching furnace during long-term use.

[0008] Preferably, the power transmission component also includes a hydraulic groove provided on the inner wall of the support plate, a connecting groove three is provided on the inner wall of the support plate, a limited position protrusion two is fixedly connected to the inner wall of the support plate, an annular block is slidably connected to the inner wall of the dry quenching furnace, a protruding ring is fixedly connected to the outer wall of the feeding funnel, and an anti-spill assembly is rotatably connected to the inner wall of the annular block.

Through the operation of the above components, when red coke is added, it is possible to avoid the continuous rise of high-temperature and high-pressure gas and the reduction of space inside the dry quenching furnace after the addition of red coke, and a large amount of high-temperature and high-pressure gas will flow outward. When these gases flow outward, they will cause the smoke, dust and some reaction-generated gases inside the dry quenching furnace to leak outward, causing pollution to the air and the environment.

[0009] Preferably, the anti-spillage assembly includes a rotating plate rotatably connected to the inner wall of the annular block, a rotating shaft is fixedly connected to the outer wall of the rotating plate, the outer wall of the rotating shaft is rotatably connected to the inner wall of the annular block, a sliding plate is slidably connected to the inner wall of the rotating plate, an arc spring is fixedly connected to the top of the rotating plate, the outer wall of the arc spring is fixedly connected to the inner wall of the annular block, when the annular block moves upward, the rotating plate loses contact with the inner wall of the dry quenching furnace, and under the action of the arc spring, it rotates downward with the rotating shaft as the axis, and when the annular block stops moving upward, the rotating plate stops moving synchronously, and its bottom just contacts the top of the dry quenching furnace.

[0010] Preferably, the anti-spill assembly also includes a rotating block rotatably connected to the bottom of the rotating plate, the bottom of the rotating block is fixedly connected to a hydraulic telescopic rod, the bottom of the hydraulic telescopic rod is fixedly connected to the inner wall of the annular block, the inner wall of the hydraulic telescopic rod is fixedly connected to a connecting pipe, the outer wall of the connecting pipe is fixedly connected to the inner wall of the rotating plate, and a hydraulic telescopic rod is provided by utilizing the characteristic that when the annular block rises, the rotating plate will rotate downward and extend under the action of an arc spring, and when the annular block moves upward, the rotating plate will rotate downward with the rotating shaft as the axis under the action of the arc spring, and when the rotating plate rotates downward, the hydraulic oil inside the hydraulic telescopic rod is squeezed by the rotating block, so that the hydraulic oil passes through The connecting pipe enters into the interior of the rotating plate and pushes the sliding plate to move outward. Then, when the annular block moves downward, it squeezes the rotating plate to rotate upward and drives the rotating block to move upward, so that the hydraulic oil inside the rotating plate flows back into the hydraulic telescopic rod, allowing the sliding plate to retract. Through the operation of the above components, when red coke is added, the sliding plate can extend outward to above the top of the furnace mouth and be tilted downward to avoid some small coke blocks in the red coke being blown to the top of the furnace mouth due to the continuous rise of high-temperature and high-pressure gas. In long-term use, the furnace mouth cannot be completely fitted with the furnace cover due to the accumulation of coke blocks, thereby affecting the sealing effect of the dry quenching furnace.

[0011] A method for using a dry quenching furnace coke sealing device comprises the following steps: S1: Power on and running; S2: Open the furnace cover; S3: Focusing is performed.

[0012] The present invention has the following beneficial effects: (1) The present invention utilizes the characteristic that the high temperature gas inside the dry quenching furnace will be accompanied by high pressure and will continue to rise, and sets a pressure plate. When the high temperature and high pressure gas inside the dry quenching furnace continues to rise, the high temperature and high pressure gas will push the pressure plate upward to move upward, so that the pressure plate squeezes the hydraulic oil on the top thereof, and the hydraulic oil enters the sealing block through the connecting groove, pushing the sealing block to move outward, so that it is closely attached to the inner surface of the dry quenching furnace furnace mouth. When the hydraulic oil pushes the sealing block to move, the hydraulic oil will also push the sealing plate outward through the connecting hole, so as to avoid that when the sealing block gradually extends outward, the sealing blocks will gradually separate from each other, resulting in a large gap, thereby affecting the sealing of the furnace top. When the sealing plate gradually extends outward, it will also move outward with the sealing block, closely attached to the furnace mouth of the dry quenching furnace, so as to enhance the sealing at the furnace mouth. Through the operation of the above components, the sealing and firmness of the furnace cover and the furnace mouth of the dry quenching furnace can be improved, and it is avoided that when the high temperature and high pressure gas continues to push upward, the edge of the furnace cover will be loosened, thereby affecting its sealing.

[0013] (2) The present invention utilizes the characteristic that the chain pulls the sliding block to raise the furnace cover, and sets an electric telescopic rod. When the electric telescopic rod is in operation, it drives the connecting rod 2 to move with the fixed block as the axis, and then drives the movable block and the sliding rod to move through the connecting rod 3, so that the sliding rod first rotates and moves downward on the fixed bracket 2, and at this time, the swing rod rotates backward synchronously, and the sliding block is pulled up by the chain, and the furnace cover is driven up to open the top of the dry quenching furnace. Then, the sliding rod is pulled and moves backward with the fixed bracket 2, so that the furnace cover leaves the top of the dry quenching furnace to facilitate the subsequent feeding. When the chain pulls the sliding block up, it will be synchronously The piston rod 1 is driven to rise, so that the piston rod 1 squeezes the water on its top, so that it pushes the telescopic rod outward through the connecting groove 2, so that the sealing block and the sealing plate that were originally close to the dry quenching furnace mouth are no longer close, to avoid the sealing block and the sealing plate being too close to the dry quenching furnace mouth under the continuous push of the high-temperature and high-pressure gas inside the dry quenching furnace, thereby increasing the pulling force when pulling the furnace cover, so that the working load of the electric telescopic rod increases and the service life decreases, and when the pulling force is too large, it may cause greater wear of the sealing block, the sealing plate and the chain, affecting the normal operation of the equipment and the sealing of the top of the dry quenching furnace during long-term use.

[0014] (3) The present invention utilizes the above-mentioned characteristic that the sliding rod will move backward with the fixed bracket 2, and sets two connecting rods 1. When the sliding rod moves backward, the fixed bracket 1 can be driven to move backward together through the connecting rod 1. When the fixed bracket 1 moves, its bottom and the roller will contact the beveled protrusion and squeeze the beveled protrusion to move downward. When the beveled protrusion moves downward, the hydraulic oil in the hydraulic groove is squeezed by the piston rod 2, so that the hydraulic oil flows to the bottom of the annular block through the connecting groove 3 and continues to push the annular block upward, so that the annular block finally fits with the protruding ring. Through the operation of the above-mentioned components, when red coke is added, it is possible to avoid a large amount of high-temperature and high-pressure gas from flowing outward due to the continuous rise of high-temperature and high-pressure gas and the reduction of space inside the dry quenching furnace after the red coke is added. When these gases flow outward, they will cause smoke, dust and some reaction-generated gases inside the dry quenching furnace to leak outward, causing pollution to the air and the environment.

[0015] (4) The present invention utilizes the characteristic that when the annular block rises, the rotating plate will rotate downward and extend out under the action of the arc spring, and sets a hydraulic telescopic rod. When the annular block moves upward, the rotating plate will rotate downward with the rotating shaft as the axis under the action of the arc spring. When the rotating plate rotates downward, the hydraulic oil inside the hydraulic telescopic rod is squeezed by the rotating block, so that the hydraulic oil enters the inside of the rotating plate through the connecting pipe and pushes the sliding plate to move outward. Then, when the annular block moves downward, it squeezes the rotating plate to rotate upward, and drives the rotating block to move upward, so that the hydraulic oil inside the rotating plate flows back into the hydraulic telescopic rod, and the sliding plate retracts. Through the operation of the above components, when red coke is added, the sliding plate can extend outward to above the top position of the furnace mouth and present a tilted downward state, so as to avoid some small coke blocks in the red coke being blown to the top position of the furnace mouth due to the continuous rise of high-temperature and high-pressure gas. In long-term use, the furnace mouth cannot be completely fitted with the furnace cover due to the accumulation of coke blocks, thereby affecting the sealing effect of the dry quenching furnace.

When the high-temperature and high-pressure gas inside the dry quenching furnace 101 continues to rise, the high-temperature and high-pressure gas will push the pressure plate 301 upward to move upward, so that the pressure plate 301 squeezes the hydraulic oil on its top, allowing the hydraulic oil to pass through the connecting groove When the hydraulic oil pushes the sealing block 304 to move, the hydraulic oil will also push the sealing plate 306 to move outward through the connecting hole 305, so as to avoid that when the sealing block 304 gradually extends outward, the sealing blocks 304 will gradually separate from each other, resulting in a larger gap, which will affect the sealing of the furnace top, and the sealing plate 306 will also move outward with the sealing block 304 when it gradually extends out, and be close to the furnace mouth of the dry quenching furnace 101 to enhance the sealing at the furnace mouth.

When the connecting rod 2 403 moves, the movable block 405 can be synchronously driven to move through the connecting rod 3 404.

When the annular block 419 moves upward, the rotating plate 501 loses contact with the inner wall of the dry quenching furnace 101, and under the action of the arc spring 504, it rotates downward with the rotating shaft 502 as the axis. When the annular block 419 stops moving upward, the rotating plate 501 stops moving synchronously, and its bottom just contacts the top of the dry quenching furnace 101.

[0026] The anti-spill assembly 5 also includes a rotating block 505 rotatably connected to the bottom of the rotating plate 501, and a hydraulic telescopic rod 506 is fixedly connected to the bottom of the rotating block 505. The bottom of the hydraulic telescopic rod 506 is fixedly connected to the inner wall of the annular block 419, and a connecting pipe 507 is fixedly connected to the inner wall of the hydraulic telescopic rod 506. The outer wall of the connecting pipe 507 is fixedly connected to the inner wall of the rotating plate 501. When the annular block 419 rises, the rotating plate 501 will rotate downward and extend under the action of the arc spring 504. A hydraulic telescopic rod 506 is set. When the annular block 419 moves upward, the rotating plate 501 is affected by the arc spring 504 and will rotate downward with the rotating shaft 502 as the axis. When the rotating plate 501 rotates downward, the hydraulic telescopic rod 506 is squeezed by the rotating block 505. The internal hydraulic oil allows the hydraulic oil to enter the interior of the rotating plate 501 through the connecting pipe 507, and push the sliding plate 503 to move outward. Then, when the annular block 419 moves downward, it will squeeze the rotating plate 501 to rotate upward, and drive the rotating block 505 to move upward, so that the hydraulic oil inside the rotating plate 501 flows back into the hydraulic telescopic rod 506, allowing the sliding plate 503 to retract. Through the operation of the above components, when red coke is added, the sliding plate 503 can extend outward to above the top position of the furnace mouth and present a tilted downward state, so as to avoid some small coke blocks in the red coke being blown to the top position of the furnace mouth due to the continuous rise of high-temperature and high-pressure gas. In long-term use, the furnace mouth cannot be completely fitted with the furnace cover 1 due to the accumulation of coke blocks, thereby affecting the sealing effect of the dry quenching furnace 101.

[0027] The method for using the CDQ furnace coke sealing device comprises the following steps: S1: Power on and running; S2: Open the furnace cover; S3: Focusing is performed.

[0028] A specific application of this embodiment is: before using the device, the device is first installed at the required position, and the power supply of the electric telescopic rod 401 is turned on. When the high-temperature and high-pressure gas in the dry quenching furnace 101 continues to rise, the high-temperature and high-pressure gas will push the pressure plate 301 upward to move upward, so that the pressure plate 301 squeezes the hydraulic oil on its top, allowing the hydraulic oil to enter the sealing block 304 through the connecting groove 1 303, pushing the sealing block 304 to move outward, so that it is close to the inner surface of the furnace mouth of the dry quenching furnace 101. When the hydraulic oil pushes the sealing block 304 to move, the hydraulic oil will also pass through the connecting hole 305. The sealing plate 306 is pushed to move outward to prevent the sealing blocks 304 from gradually separating from each other when the sealing blocks 304 gradually extend outward, resulting in a larger gap and affecting the sealing of the furnace top. When the sealing plate 306 is gradually extended, it will also move outward with the sealing block 304 and be close to the furnace mouth of the dry quenching furnace 101 to enhance the sealing at the furnace mouth. Through the operation of the above components, the sealing and firmness of the furnace cover 1 and the furnace mouth of the dry quenching furnace 101 can be improved, and it is avoided that the edge of the furnace cover 1 is loosened when the high-temperature and high-pressure gas is continuously pushed upward, thereby affecting its sealing.

[0029] By utilizing the characteristic that the chain 409 pulls the sliding block 410 to make the furnace cover 1 rise, an electric telescopic rod 401 is provided. When the electric telescopic rod 401 is in operation, it drives the second connecting rod 403 to move with the fixed block 402 as the axis, and then drives the movable block 405 and the sliding rod 406 to move through the third connecting rod 404, so that the sliding rod 406 first rotates and moves downward on the second fixed bracket 408, and at this time, the swing rod 407 rotates backward synchronously, and pulls the sliding block 410 up through the chain 409, and drives the furnace cover 1 to rise, so that the top of the dry quenching furnace 101 is opened, and then the sliding rod 406 is pulled along with the second fixed bracket 408. When the chain 409 pulls the sliding block 410 upward, the piston rod 1 411 will be driven upward synchronously, so that the piston rod 1 411 squeezes the water on the top thereof, so that the piston rod 1 411 pushes the telescopic rod 302 outward through the connecting groove 2 413, so that the sealing block 304 and the sealing plate 306 that were originally close to the furnace opening of the dry quenching furnace 101 are no longer close to each other, so as to avoid the sealing block 304 and the sealing plate 306 being too close to the furnace opening of the dry quenching furnace 101 under the continuous push of the high-temperature and high-pressure gas inside the dry quenching furnace 101, thereby increasing the pulling force when pulling the furnace cover 1, so that the electric The working load of the telescopic rod 401 increases and the service life decreases. When the tension is too large, it may cause greater wear of the sealing block 304, the sealing plate 306 and the chain 409. In long-term use, the normal operation of the equipment and the sealing of the top of the dry quenching furnace 101 are affected. When the sliding rod 406 moves backward, the connecting rod 1 205 can drive the fixed bracket 1 202 to move backward together. When the fixed bracket 1 202 moves, its bottom and the roller 203 will contact the angled protrusion 414 and squeeze the angled protrusion 414 to move downward. When the angled protrusion 414 moves downward, the piston rod 2 415 The hydraulic oil in the hydraulic groove 416 is squeezed to flow to the bottom of the annular block 419 through the connecting groove three 417, and the annular block 419 is continuously pushed upward so that the annular block 419 finally fits with the protruding ring 420. Through the operation of the above components, when red coke is added, it is possible to avoid that a large amount of high-temperature and high-pressure gas will flow outward due to the continuous rise of high-temperature and high-pressure gas and the reduction of the space inside the dry quenching furnace 101 after the addition of red coke. When these gases flow outward, the smoke, dust and some reaction-generated gases inside the dry quenching furnace 101 will leak outward, causing pollution to the air and the environment.

[0030] Taking advantage of the fact that when the annular block 419 rises, the rotating plate 501 will rotate downward and extend under the action of the arc spring 504, a hydraulic telescopic rod 506 is set. When the annular block 419 moves upward, the rotating plate 501 is acted upon by the arc spring 504 and will rotate downward with the rotating shaft 502 as the axis. When the rotating plate 501 rotates downward, the hydraulic oil inside the hydraulic telescopic rod 506 is squeezed by the rotating block 505, so that the hydraulic oil enters the interior of the rotating plate 501 through the connecting pipe 507 and pushes the sliding plate 503 to move outward. Then, when the annular block 419 moves downward, it squeezes the hydraulic oil inside the hydraulic telescopic rod 506. The rotating plate 501 rotates upward and drives the rotating block 505 to move upward, so that the hydraulic oil inside the rotating plate 501 flows back into the hydraulic telescopic rod 506, allowing the sliding plate 503 to retract. Through the operation of the above components, when red coke is added, the sliding plate 503 can be extended outward to above the top of the furnace mouth and present a tilted downward state, so as to prevent some small coke blocks in the red coke from being blown to the top of the furnace mouth due to the continuous rise of high-temperature and high-pressure gas. In long-term use, the furnace mouth cannot be completely fitted with the furnace cover 1 due to the accumulation of coke blocks, thereby affecting the sealing effect of the dry quenching furnace 101.
