Description

Technical Field

[0001] This utility model relates to the field of breaking devices, specifically to a breaking device for slag accumulation at the slag inlet of a multi-nozzle gasification furnace for coal-water slurry. Background Technology

[0002] During gasifier operation, the ash content of the coal slows down the flow of slag at lower operating temperatures, leading to accumulation and blockage at the slag inlet. During furnace drying, if the heating rate is too rapid, the slag adhering to the furnace wall will gradually melt as the drying temperature rises, slowly flowing towards the bottom of the cone. Because the temperature at the bottom of the cone is lower, this slag will cool rapidly at the slag inlet, causing blockage. Once blockage occurs, the furnace must be shut down and the slag inlet cleared.

[0003] A search revealed that Chinese patent CN222058381U discloses a "Slag Removal Device for Coal-Water Slurry Gasification Furnace Slag Inlet," comprising a first vertical beam, an outer ring of a first bearing fixedly mounted on the top of the first vertical beam, an inner ring of the first bearing fixedly connected to one side of a first horizontal beam, another side of the first horizontal beam fixedly connected to one side of a drum, another side of the drum fixedly connected to one side of a second horizontal beam, and the other side of the second horizontal beam fixedly connected to the inner ring of a second bearing. The outer ring of the second bearing is fixedly mounted on the top of the second vertical beam. A rocker arm is also provided on the inner ring of the first bearing. A steel wire rope is wound around the drum, one end of which is fixedly mounted on the drum, and the other end, a movable end, is fixedly mounted with a weight. This device, on the one hand, can generate greater energy to hammer the slag when the weight falls, and on the other hand, can control the height of the weight after falling by adjusting the position of the upper limit buckle of the steel wire rope, effectively avoiding damage to the gasifier and other equipment due to excessive falling during the weight's descent. However, it still has the following drawbacks: (1) Although the existing breaking device can adjust the collision height by rocker, it cannot accurately collide with the slag in the vertical direction of the slag outlet pipe. It can only achieve the vibration breaking of the internal slag in the vertical direction through collision transmission. The vibration transmission generated by the collision has a decrease in force, so a larger collision force or a longer collision time is required to complete the complete breaking, which reduces the scope of application of the breaking device.

[0004] (2) The existing breaking device uses an external pendulum to collide with the slag outlet pipe, which takes up a lot of space and the collision position is not accurate enough, thus reducing the effectiveness of the breaking device.

[0005] Therefore, we have made improvements to this and proposed a slag removal device for multi-nozzle gasification furnace slag mouth of coal-water slurry. Utility Model Content

[0006] The purpose of this invention is to address the following issues: While existing breaking devices can adjust the collision height with a rocker arm, they cannot precisely collide with the slag accumulation in the vertical direction of the slag outlet pipe. They can only achieve vibration breaking of the internal slag accumulation in the vertical direction through collision transmission. The vibration transmission generated by the collision has a decreasing force, thus requiring a larger collision force or a longer collision time to complete the complete breaking, which reduces the application range of the breaking device. Furthermore, existing breaking devices use an external pendulum to collide with the slag outlet pipe, which occupies a large space and lacks sufficient accuracy in the collision position, thus reducing the effectiveness of the breaking device.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution: A slag removal device for multi-nozzle gasification furnace slag inlet of coal-water slurry is provided to improve the above-mentioned problems.

[0008] The present invention is as follows: The furnace body includes a slag inlet pipe at the right end of the furnace body, an adjustment component on the outer wall of the slag inlet pipe, and a striking component outside the adjustment component. The adjustment assembly includes a fixing ring that is fixedly fitted to the outer wall of the slag outlet pipe. The fixing ring has a groove at its center, and an insert ring is rotatably arranged inside the groove. The striking assembly includes vertical plates symmetrically installed on the outer wall of the side of the ring away from the slag outlet pipe. A rotating roller is rotatably arranged between the vertical plates, and a motor is connected to the side wall of the rotating roller through the vertical plate.

[0009] As a preferred technical solution of this utility model, symmetrical limiting grooves are provided on both sides of the annular groove, and limiting rings that cooperate with the limiting grooves are provided on both sides of the embedded ring.

[0010] As a preferred technical solution of this utility model, a slot is provided on the right side of the limiting ring, an electric roller is rotatably arranged inside the slot, and a toothed ring that cooperates with the electric roller is provided on the inner wall of the right side of the limiting groove.

[0011] As a preferred technical solution of this utility model, the striking component further includes a telescopic groove opened inside the center of the embedded ring, a telescopic plate slidably arranged inside the telescopic groove, and a force-bearing block that cooperates with the rotating roller is fixedly installed on the surface of the telescopic plate away from the slag outlet pipe.

[0012] As a preferred technical solution of this utility model, the telescopic groove is symmetrically provided with side grooves on both sides, and the telescopic plate is symmetrically provided with side plates that cooperate with the side grooves on both sides.

[0013] As a preferred technical solution of this utility model, a spring rod is fitted on the surface of the side plate near the slag outlet pipe.

[0014] As a preferred technical solution of this utility model, a striking block is fixedly installed on the outer wall of the telescopic plate near the slag outlet pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: In the solution of this utility model: 1. By using the embedded ring, limiting ring, and electric roller, when it is necessary to break up the slag accumulated in different directions of the slag outlet pipe, it is necessary to adjust the position of the breaking structure and control the rotation of the electric roller so that it meshes with the toothed ring surface set on the side wall of the limiting groove. With the limiting ring embedded in the limiting groove, the embedded ring rotates stably around the groove, which can drive the breaking device to rotate around the slag outlet pipe. The direction of the breaking structure can be precisely adjusted, making the breaking more thorough and improving the application range of the breaking device. 2. Through the configuration of rotating rollers, telescopic plates, force-bearing blocks, side plates, spring rods, and impact blocks, when it is necessary to remove slag accumulation inside the slag outlet pipe, the direction of the striking assembly is adjusted and positioned, and the motor is controlled to drive the connected elliptical rotating roller to rotate. When the long diameter end of the elliptical rotating roller rotates to a vertical position, it generates a downward instantaneous thrust on the arc surface of the force-bearing block, causing the force-bearing block to move downward. With the side plate embedded in the side groove, the telescopic plate moves vertically downward in the telescopic groove, thereby driving the impact block to move rapidly towards the slag outlet pipe and impact the slag outlet pipe instantaneously. At the same time, the movement of the side plate squeezes the spring rod, causing it to contract. When the short diameter end of the elliptical rotating roller rotates close to the force-bearing block, the force-bearing block loses the thrust towards the slag outlet pipe. The spring rod pushes the side plate, causing the telescopic plate to move away from the slag outlet pipe, so that the impact block can reset and be impacted again towards the slag outlet pipe. Under the high-frequency rotation of the rotating roller, the impact block performs a high-frequency impact on the slag outlet pipe at a precise position, improving the thoroughness of slag accumulation removal.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0019] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0020] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] like Figure 1-4 As shown, this embodiment proposes a slag removal device for a multi-nozzle gasifier slag inlet of a coal-water slurry gasifier, including a furnace body 1. A slag inlet pipe 2 is provided at the right end of the furnace body 1. An adjustment component is provided on the outer wall of the slag inlet pipe 2. A knocking component is provided outside the adjustment component. The adjustment assembly includes a fixing ring 301 fixedly fitted on the outer wall of the slag outlet pipe 2. The fixing ring 301 has a ring groove 302 in the center, and an embedded ring 303 is rotatably arranged inside the ring groove 302. The striking assembly includes vertical plates 401 symmetrically installed on the outer wall of the side of the embedded ring 303 away from the slag outlet pipe 2. A rotating roller 402 is rotatably arranged between the vertical plates 401. A motor 403 is connected to the side wall of the rotating roller 402 through the vertical plates 401.

[0023] like Figure 1As shown, the annular groove 302 has symmetrically opened limiting grooves 304 on both sides, and the embedded ring 303 has limiting rings 305 on both sides that cooperate with the limiting grooves 304. With the limiting rings 305 embedded in the limiting grooves 304, the embedded rings 303 can rotate stably in the annular groove 302, which can drive the breaking device to rotate around the slag outlet pipe 2.

[0024] like Figure 2 As shown, a slot 306 is provided on the right side of the limiting ring 305. An electric roller 307 is rotatably installed inside the slot 306. A toothed ring that cooperates with the electric roller 307 is provided on the inner wall of the right side of the limiting groove 304. When it is necessary to break up the slag accumulated in different directions of the slag outlet pipe 2, it is necessary to adjust the position of the breaking structure and control the electric roller 307 to rotate so that it meshes with the toothed ring surface provided on the side wall of the limiting groove 304.

[0025] like Figure 3 As shown, the striking assembly also includes a telescopic groove 404 opened inside the center of the embedded ring 303. A telescopic plate 405 is slidably arranged inside the telescopic groove 404. A force-bearing block 406 that cooperates with the rotating roller 402 is fixedly installed on the surface of the telescopic plate 405 away from the slag outlet pipe 2. When it is necessary to remove the slag inside the slag outlet pipe 2, after adjusting the direction and positioning of the striking assembly, the motor 403 is controlled to drive the elliptical rotating roller 402 connected to it to rotate. When the long diameter end of the elliptical rotating roller 402 is rotated to a vertical state, it generates a downward instantaneous thrust on the arc surface of the force-bearing block 406, causing the force-bearing block 406 to move downward. Under the limitation of the side plate 408 being embedded in the side groove 407, the telescopic plate 405 moves vertically downward in the telescopic groove 404, thereby driving the impact block 410 to move rapidly towards the slag outlet pipe 2 and instantly impact the slag outlet pipe 2.

[0026] like Figure 3 As shown, the telescopic groove 404 is symmetrically provided with side grooves 407 on both sides, and the telescopic plate 405 is symmetrically provided with side plates 408 that cooperate with the side grooves 407 on both sides. With the side plates 408 embedded in the side grooves 407, the telescopic plate 405 moves vertically downward in the telescopic groove 404, thereby driving the impact block 410 to move rapidly in the direction of the slag outlet pipe 2.

[0027] like Figure 4 As shown, a spring rod 409 is fitted on the side surface of the side plate 408 near the slag outlet pipe 2. The spring rod 409 pushes the side plate 408 to move the telescopic plate 405 away from the slag outlet pipe 2, so that the impact block 410 is reset.

[0028] like Figure 4As shown, a striking block 410 is fixedly installed on the outer wall of the telescopic plate 405 near the slag outlet pipe 2. The force block 406 moves downward, and under the limitation of the side plate 408 being embedded in the side groove 407, the telescopic plate 405 moves vertically downward in the telescopic groove 404, thereby driving the striking block 410 to move rapidly towards the slag outlet pipe 2 and instantly impact the slag outlet pipe 2.

[0029] Specifically, when using this breaking device: When it is necessary to break up slag accumulated in different directions on the slag nozzle 2, the position of the breaking structure needs to be adjusted. The electric roller 307 is controlled to rotate so that it meshes with the toothed ring surface on the side wall of the limiting groove 304. With the limiting ring 305 embedded in the limiting groove 304, the embedded ring 303 rotates stably within the ring groove 302, thus driving the breaking device to rotate around the slag nozzle 2. Precise adjustment of the direction of the breaking structure makes the breaking more thorough, increasing the application range of the breaking device. When it is necessary to break up slag accumulated inside the slag nozzle 2, after adjusting the direction and positioning of the striking component, the motor 403 is controlled to rotate, driving the connected elliptical roller 402 to rotate. When the long-diameter end of the elliptical roller 402 is in a vertical state, it exerts a downward instantaneous force on the arc-shaped surface of the force block 406. The thrust between the two forces causes the force-bearing block 406 to move downwards. With the side plate 408 embedded in the side groove 407, the telescopic plate 405 moves vertically downwards within the telescopic groove 404, thereby driving the impact block 410 to move rapidly towards the slag outlet pipe 2 and impact the slag outlet pipe 2 instantaneously. At the same time, the side plate 408 moves and squeezes the spring rod 409, causing it to contract. When the short-diameter end of the elliptical roller 402 rotates and approaches the force-bearing block 406, the force-bearing block 406 loses the thrust towards the slag outlet pipe 2. The spring rod 409 pushes the side plate 408 to drive the telescopic plate 405 to move away from the slag outlet pipe 2, causing the impact block 410 to reset so that it can be impacted again towards the slag outlet pipe 2. Under the high-frequency rotation of the roller 402, the impact block 410 makes a high-frequency impact on the slag outlet pipe 2 at a precise position, improving the thoroughness of slag removal.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
