Description

Technical Field

[0001] This invention belongs to the field of coal slime drying technology, and specifically relates to a coal slime steam drying device. Background Technology

[0002] Thermal power plants use a large amount of coal during operation. In order to save costs, power plants often use coal slime instead of coal to generate electricity (coal slime is much cheaper than coal). However, because coal slime has too high a water content, it cannot be used directly.

[0003] Currently, the common method used by power plants is to manually transport coal slime to an open area, spread it out to dry in the sun, and then use it. The disadvantage is that the coal slime has too high a moisture content and the sun drying cycle is too long, often not enough time to use it. As a result, a large amount of high-quality coal has to be used, which not only makes the coal slime unusable and wastes a lot of energy, but also increases the cost of manual transportation and drying.

[0004] Therefore, a coal slime steam drying device is designed to solve the above problems. Summary of the Invention

[0005] To address the problems mentioned in the background section, this invention provides a coal slime steam drying device. By heating an S-shaped cylinder and the air flowing inside it with steam, the coal slime is heated and dried while flowing within the S-shaped cylinder, improving the drying effect. Simultaneously, the coal slime can be continuously dispersed twice to ensure the drying effect. This accelerates the sliding of the coal slime on the surface of the vibrating plate, preventing accumulation inside the S-shaped cylinder. It also facilitates the upward and sudden downward movement of the outer casing when the coal slime accumulates inside the S-shaped cylinder, using vibration to aid the sliding of the coal slime within the cylinder.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] like Figures 1 to 14 As shown;

[0043] A coal slime steam drying device includes an outer casing 1 and a base 3 disposed below the outer casing 1, and a drying mechanism 2 disposed inside the outer casing 1. The drying mechanism 2 includes a drying component 21, a heating component 22, a dispersing component 23, a pushing component 24, a shaking component 25, and an oscillating component 26.

[0044] The drying assembly 21 includes an S-shaped material cylinder 211, an inner box 212, an upper gas guide plate 213, a first steam guide plate 214, a second steam guide plate 215, a first U-shaped connecting pipe 216, an exhaust pipe 217, an intake pipe 218, a second U-shaped connecting pipe 219, a receiving hopper 2110, and a lower gas guide plate 2111. The inner box 212 is located inside the outer box 1. The upper gas guide plate 213 and the lower gas guide plate 2111 are fixedly connected inside the inner box 212. The upper gas guide plate 213 is located below the lower gas guide plate 2111. Above the upper gas guide plate 213 and the lower gas guide plate 2111, an S-shaped material cylinder 211 is arranged between them. The two ends of the S-shaped material cylinder 211 pass through the outer box 1 and the inner box 212 respectively. The S-shaped material cylinder 211 is fixedly connected to the inner box 212 and the outer box 1 respectively. The inner box 212 is fixedly connected to the first steam guide plate 214 and the second steam guide plate 215. The first steam guide plate 214 is located above the second steam guide plate 215. The first steam guide plate 214, the second steam guide plate 215, the upper gas guide plate 213 and the lower gas guide plate 2111 are arranged in a series. The guide plates 2111 all have suitable gaps with the S-shaped barrel 211. A second U-shaped connecting pipe 219 is inserted into the front surface of the outer casing 1. The two ends of the second U-shaped connecting pipe 219 are inserted into the surface of the inner casing 212 and extend into the interior of the inner casing 212. The two ends of the second U-shaped connecting pipe 219 are respectively located between the second steam guide plate 215 and the lower gas guide plate 2111, and the S-shaped barrel 211 is located between the two ends of the second U-shaped connecting pipe 219. An air inlet pipe 218 is inserted into the upper surface of the second U-shaped connecting pipe 219. The front surface of the outer casing 1 is inserted with... A first U-shaped connecting pipe 216 is provided, with both ends of the first U-shaped connecting pipe 216 inserted into the surface of the inner box 212 and extending into the interior of the inner box 212. The two ends of the first U-shaped connecting pipe 216 are respectively located between the upper gas guide plate 213 and the first steam guide plate 214, and the S-shaped material cylinder 211 is located between the two ends of the first U-shaped connecting pipe 216. A receiving hopper 2110 is provided on the left side of the outer box 1, and one end of the receiving hopper 2110 and the S-shaped material cylinder 211 are fixedly connected. An exhaust pipe 217 is inserted into the upper surface of the first U-shaped connecting pipe 216.

[0045] In this embodiment: Steam flows along the inside of the inlet pipe 218 into the inside of the second U-shaped connecting pipe 219, and then into the upper and lower surfaces of the S-shaped cylinder 211. With appropriate gaps between the upper gas guide plate 213, the first steam guide plate 214, the second steam guide plate 215, and the lower gas guide plate 2111 and the S-shaped cylinder 211, the steam flows along the surface of the S-shaped cylinder 211 and into the inside of the first U-shaped connecting pipe 216, and then along the inside of the exhaust pipe 217. The coal slurry flows out of the S-shaped feed cylinder 211, thereby heating the S-shaped feed cylinder 211 with steam. The coal slurry is poured into the receiving hopper 2110 and flows along the inside of the receiving hopper 2110 and the inside of the S-shaped feed cylinder 211, and flows out from the other end of the S-shaped feed cylinder 211. When the coal slurry passes through the heated S-shaped feed cylinder 211, the S-shaped feed cylinder 211 can heat and dry the coal slurry. The coal slurry can be heated and dried when it flows inside the S-shaped feed cylinder 211 by steam heating.

[0046] It should be noted that when there are appropriate gaps between the upper gas guide plate 213, the first steam guide plate 214, the second steam guide plate 215, and the lower gas guide plate 2111 and the S-shaped barrel 211, the steam flows along the surface of the S-shaped barrel 211, thereby heating the S-shaped barrel 211 and the inner box 212 through the temperature of the steam. The setting of the second U-shaped connecting pipe 219 can make the steam flow in two paths, and under the action of the first U-shaped connecting pipe 216, the steam in both paths can flow out, ensuring the heating effect of the S-shaped barrel 211.

[0047] Furthermore:

[0048] In an optional embodiment, the heating assembly 22 includes an air pump 221, a bent guide pipe 222, a third U-shaped connecting pipe 223, a fourth U-shaped connecting pipe 224, and an air guide shroud 225. The air pump 221 is mounted on the upper surface of the outer casing 1. The exhaust end of the air pump 221 is fixedly connected to the bent guide pipe 222. The end of the bent guide pipe 222 away from the air pump 221 is inserted into the surface of the outer casing 1 and extends between the inner casing 212 and the outer casing 1. The third U-shaped connecting pipe is inserted into the surface of the outer casing 1. 223, the two ends of the third U-shaped connecting pipe 223 extend into the interior of the outer box 1. The two ends of the third U-shaped connecting pipe 223 are located between the inner box 212 and the outer box 1. An air guide hood 225 is installed inside the S-shaped material cylinder 211. A fourth U-shaped connecting pipe 224 is inserted into the surface of the outer box 1. Both ends of the fourth U-shaped connecting pipe 224 extend into the space between the outer box 1 and the inner box 212. One end of the fourth U-shaped connecting pipe 224 passes through the S-shaped material cylinder 211 and is inserted into the surface of the air guide hood 225.

[0049] In this implementation scheme: the operation of the air pump 221 allows external air to flow into the space between the inner box 212 and the outer box 1 along the inside of the bent guide pipe 222. As the steam flows along the surface of the S-shaped material cylinder 211, it heats both the S-shaped material cylinder 211 and the inner box 212. When the external air flows along the surface of the inner box 212, the inner box 212, which has a certain temperature, heats the flowing air. Under the action of the third U-shaped connecting pipe 223, the air can bypass the S-shaped material cylinder. 211, and flows to the bottom of the built-in box 212. The heated air flows into the interior of the fourth U-shaped connecting pipe 224, and flows into the interior of the air guide hood 225 along the interior of the fourth U-shaped connecting pipe 224, and flows out from the interior of the air guide hood 225. When the heated air flows out from the interior of the air guide hood 225, it flows along the interior of the S-shaped material cylinder 211 and flows out. When the heated air flows inside the S-shaped material cylinder 211, it can dry the coal slime inside the S-shaped material cylinder 211, further improving the coal slime drying effect.

[0050] It should be noted that: a condensate valve is installed on the bottom of the outer casing 1 to facilitate the timely discharge of condensate. Under the action of the third U-shaped connecting pipe 223, air can bypass the S-shaped material cylinder 211 and flow to the bottom of the inner casing 212. Under the action of the fourth U-shaped connecting pipe 224, the heated air can flow out from the inside of the air guide shroud 225.

The main rotating shaft 232 passes through the outer casing 1, the inner casing 212, and the S-shaped material cylinder 211. The outer casing 1, the inner casing 212, and the S-shaped material cylinder 211 are all rotatably connected to the main rotating shaft 232. Three grate lifting plates 233 arranged in a circular array are fixedly connected to the surface of the main rotating shaft 232. All three grate lifting plates 233 are located in the S-shaped material cylinder. Inside the S-shaped cylinder 211, a driven shaft 2315 is located below the main rotating shaft 232. The driven shaft 2315 is fixedly connected to the inside of the S-shaped cylinder 211. A double-sided grate plate 2314 is fitted on the surface of the driven shaft 2315. The double-sided grate plate 2314 and the driven shaft 2315 are rotatably connected. The dispersing assembly 23 also includes a rectangular plate 234, a positioning plate 235, a spring 237, a fixing plate 238, a connecting plate 2310, a first U-shaped block 2311, a first support rod 2312, a second U-shaped block 2313, a first pin 2316, and a second pin 2317. A T-shaped groove 236 is provided in the inner wall of the S-shaped cylinder 211. The system includes a positioning plate 235 and a connecting plate 2310. The positioning plate 235 is located above the connecting plate 2310. The positioning plate 235 is fixedly connected to the S-shaped material cylinder 211, and the connecting plate 2310 is slidably connected to the S-shaped material cylinder 211. A rectangular plate 234 is fixedly connected to the side of the connecting plate 2310 near the main rotating shaft 232. A spring 237 and a fixing plate 238 are installed in a square groove 239 inside the connecting plate 2310. The fixing plate 238 is fixedly connected to the S-shaped material cylinder 211. The two ends of the spring 237 are fixedly connected to the connecting plate 2310 and the fixing plate 238, respectively. The fixing plate 238 and the connecting plate 2310 are slidably connected. A first U-shaped block 2311 is provided below 234. The first U-shaped block 2311 is fixedly connected to the connecting plate 2310. A first pin 2316 is fixedly connected inside the first U-shaped block 2311. A first support rod 2312 is sleeved on the surface of the first pin 2316. The first support rod 2312 and the first pin 2316 are rotatably connected. A second U-shaped block 2313 is fixedly connected to the upper surface of the double-sided grate plate 2314. A second pin 2317 is fixedly connected inside the second U-shaped block 2313. The second pin 2317 passes through one end of the first support rod 2312. The first support rod 2312 and the second pin 2317 are rotatably connected.

[0053] In this implementation scheme: the operation of the first motor 231 drives the main rotating shaft 232 to rotate, the rotation of the main rotating shaft 232 drives the grate lifting plate 233 to rotate synchronously, the rotation of the grate lifting plate 233 drives the rectangular plate 234 to move, the movement of the rectangular plate 234 drives the connecting plate 2310 to move synchronously, thereby compressing the spring 237. When the grate lifting plate 233 slides off the surface of the rectangular plate 234, under the action of the elastic potential energy of the spring 237, the connecting plate 2310 can move rapidly in the opposite direction. When the connecting plate 2310 moves... The first support rod 2312 can drive the double-sided grate plate 2314 to rotate around the driven shaft 2315. When the connecting plate 2310 moves rapidly in the opposite direction, it can drive the double-sided grate plate 2314 to rotate rapidly in the opposite direction. When the coal slime comes into contact with the rotating grate bar lifting plate 233, the rotation of the grate bar lifting plate 233 can break up the coal slime. The rotation and rapid reverse rotation of the double-sided grate plate 2314 can further break up the coal slime. This is beneficial for breaking up the coal slime twice in a row, avoiding the problem of coal slime clumping and poor coal slime drying effect.

[0055] In an optional embodiment, the pushing assembly 24 includes a third U-shaped block 241, a second support rod 242, a pushing rod 243, and a third pin 244. The bottom surface of the double-sided grate 2314 is fixedly connected to the third U-shaped block 241, and the interior of the third U-shaped block 241 is fixedly connected to the third pin 244. The surface of the third pin 244 is fitted with the second support rod 242, and the second support rod 242 and the third pin 244 are rotatably connected. The end of the second support rod 242 away from the double-sided grate 2314 is fixedly connected to the pushing rod 243.

[0056] In this implementation scheme: the rotation and rapid reverse rotation of the double-sided grate plate 2314 can drive the second support rod 242 to slide on the surface of the shaking plate 253, thereby pushing the coal slurry above the shaking plate 253 to move, avoiding the coal slurry from accumulating inside the S-shaped feed cylinder 211, and facilitating the movement of the coal slurry inside the S-shaped feed cylinder 211.

[0057] Furthermore:

The shaking plate 253 is disposed below the double-sided grate 2314. The auxiliary rotating shaft 255 is fixedly connected to the auxiliary rotating groove 254 opened in the inner wall of the S-shaped barrel 211. The square plate 256 is sleeved on the surface of the auxiliary rotating shaft 255. The square plate 256 is fixedly connected to the bottom surface of the shaking plate 253. The square plate 256 and the auxiliary rotating shaft 255 rotate... The vibrating plate 253 is fixedly connected to a connecting grate 257 at one end. A rope 258 is provided above the vibrating plate 253. The two ends of the rope 258 are fixedly connected to the vibrating plate 253 and the double-sided grate 2314, respectively. The vibrating plate 253 is located in the fitting groove 251 opened inside the S-shaped material cylinder 211.

The baffle 252 is fixedly connected to the S-shaped material cylinder 211.

[0059] In this implementation scheme: when the double-sided grate plate 2314 rotates and rotates rapidly in the opposite direction, the rope 258 can drive the shaking plate 253 to rotate and shake around the auxiliary rotating shaft 255, which can accelerate the sliding of coal slime on the surface of the shaking plate 253 and prevent coal slime from accumulating inside the S-shaped feed cylinder 211.

[0060] It should be noted that the setting of the connecting grate 257 can further disperse the coal slime and further ensure the effect of coal slime drying.

[0061] Furthermore:

[0062] In an optional embodiment, the oscillation assembly 26 includes a second motor 261, a connecting shaft 262, a rotating roller 263, and an arc-shaped protrusion 264. The second motor 261 is mounted on the front surface of the base 3. The end of the output shaft of the second motor 261 is fixedly connected to the connecting shaft 262. The connecting shaft 262 passes through the base 3 and is rotatably connected to the base 3. The rotating roller 263 is sleeved on the surface of the connecting shaft 262. A through groove 266 is formed on the upper surface of the base 3. The rotating roller 263 is located inside the through groove 266. The rotating roller 263 and the connecting shaft 262 are fixedly connected. The surface of the rotating roller 263 is fixedly... An arc-shaped protrusion 264 is fixedly connected to the outer casing 1. An arc-shaped groove 265 is opened on the bottom surface of the outer casing 1. The arc-shaped protrusion 264 is located inside the arc-shaped groove 265. Four guide grooves 268 are opened on the upper surface of the base 3. A guide post 267 is inserted into the interior of each guide groove 268. The guide post 267 is fixedly connected to the outer casing 1 and slidably connected to the base 3. A rectangular slider 2610 is fixedly connected to the upper surface of the base 3. A rectangular sliding sleeve 269 is fitted on the surface of the rectangular slider 2610. The rectangular slider 2610 and the rectangular sliding sleeve 269 are slidably connected. The rectangular sliding sleeve 269 is fixedly connected to the outer casing 1.

[0063] In this implementation scheme: the operation of the second motor 261 drives the connecting shaft 262 to rotate, the rotation of the connecting shaft 262 drives the rotating roller 263 to rotate, and the rotation of the rotating roller 263 drives the arc-shaped protrusion 264 to rotate. When the arc-shaped protrusion 264 rotates to the position of the arc-shaped groove 265, the outer box 1 can suddenly drop under the action of gravity, and the guide column 267 hits the base 3, thereby causing the outer box 1 to vibrate, thus assisting the coal slime to slide inside the S-shaped material cylinder 211. During the movement of the outer box 1, the guide column 267 can slide inside the guide groove 268, and the rectangular sliding sleeve 269 slides on the surface of the rectangular slider 2610, which can ensure the stability of the outer box 1 during vertical movement. This is beneficial for the outer box 1 to rise and then suddenly drop when the coal slime accumulates inside the S-shaped material cylinder 211, and assists the coal slime to slide inside the S-shaped material cylinder 211 under the action of vibration.

[0064] Working principle: When the device is in use, the steam inlet is connected to the inlet pipe 218. The steam flows along the inside of the inlet pipe 218 into the inside of the second U-shaped connecting pipe 219, and then into the upper and lower surfaces of the S-shaped material cylinder 211. With appropriate gaps between the upper gas guide plate 213, the first steam guide plate 214, the second steam guide plate 215, and the lower gas guide plate 2111 and the S-shaped material cylinder 211, the steam flows along the surface of the S-shaped material cylinder 211 and into the inside of the first U-shaped connecting pipe 216, and then flows out along the inside of the exhaust pipe 217. Thus, the steam heats the S-shaped material cylinder 211, causing the coal slurry to be poured into the receiving hopper 2110, where it flows along the inside of the hopper. The coal slime flows along the inside of the S-shaped feed cylinder 211 and exits from the other end of the S-shaped feed cylinder 211. When the coal slime passes through the heated S-shaped feed cylinder 211, the S-shaped feed cylinder 211 can heat and dry the coal slime. The S-shaped feed cylinder 211 is heated by steam, and the coal slime is heated and dried as it flows inside the S-shaped feed cylinder 211. During the flow of the coal slime inside the S-shaped feed cylinder 211, the air pump 221 is connected to an external power source. The operation of the air pump 221 allows external air to flow along the inside of the bent guide pipe 222 into the space between the inner box 212 and the outer box 1. Due to the steam flowing on the surface of the S-shaped feed cylinder 211, the steam heats the S-shaped feed cylinder 211 while simultaneously heating the inner box 212. The external air flows along the inner box 212... When the air flows on the surface of 12, the built-in box 212, which has a certain temperature, can heat the flowing air. Under the action of the third U-shaped connecting pipe 223, the air can bypass the S-shaped material cylinder 211 and flow to the bottom of the built-in box 212. The heated air flows into the interior of the fourth U-shaped connecting pipe 224 and flows into the interior of the air guide shroud 225 along the interior of the fourth U-shaped connecting pipe 224, and then flows out from the interior of the air guide shroud 225. When the heated air flows out from the interior of the air guide shroud 225, it flows along the interior of the S-shaped material cylinder 211 and flows out. When the heated air flows inside the S-shaped material cylinder 211, it can dry the coal slime inside the S-shaped material cylinder 211, further improving the coal slime drying effect, and making the connection line of the first motor 231 and the external With the power supply connected, the operation of the first motor 231 drives the main rotating shaft 232 to rotate. The rotation of the main rotating shaft 232 drives the grate lifting plate 233 to rotate synchronously. The rotation of the grate lifting plate 233 drives the rectangular plate 234 to move. The movement of the rectangular plate 234 drives the connecting plate 2310 to move synchronously, thereby compressing the spring 237. When the grate lifting plate 233 slides off the surface of the rectangular plate 234, the elastic potential energy of the spring 237 causes the connecting plate 2310 to move rapidly in the opposite direction. When the connecting plate 2310 moves, it can drive the double-sided grate plate 2314 to rotate around the driven rotating shaft 2315 through the first support rod 2312. When the connecting plate 2310 moves rapidly in the opposite direction, it can drive the double-sided grate plate 2314 to rotate rapidly in the opposite direction.When the coal slime comes into contact with the rotating grate baffle 233, the rotation of the grate baffle 233 can break up the coal slime. The rotation and rapid counter-rotation of the double-sided grate 2314 can further break up the coal slime, which is beneficial for breaking up the coal slime twice in succession and avoids the problem of coal slime clumping leading to poor coal slime drying effect. The rotation and rapid counter-rotation of the double-sided grate 2314 can drive the second support rod 242 to slide on the surface of the vibrating plate 253, thereby pushing the vibrating plate 253 upward. The movement of the coal slime in the square shape prevents it from accumulating inside the S-shaped feed cylinder 211, facilitating its movement. Furthermore, the rotation and rapid reverse rotation of the double-sided grate 2314, via the rope 258, drive the vibrating plate 253 to rotate and vibrate around the auxiliary shaft 255, accelerating the sliding of the coal slime on the surface of the vibrating plate 253 and preventing its accumulation inside the S-shaped feed cylinder 211. The connecting grate 257 further disperses the coal slime, ensuring even movement. The effect of coal slime drying is achieved when the coal slime accumulates inside the S-shaped material cylinder 211. The connecting wire of the second motor 261 is connected to an external power source. The operation of the second motor 261 drives the connecting shaft 262 to rotate. The rotation of the connecting shaft 262 drives the rotating roller 263 to rotate. The rotation of the rotating roller 263 drives the arc-shaped protrusion 264 to rotate. When the arc-shaped protrusion 264 rotates to the position of the arc-shaped groove 265, under the action of gravity, the outer box 1 suddenly drops, causing the guide column 267 to hit the base 3, thus causing the outer box 1 to vibrate. This assists the coal slime in sliding inside the S-shaped material cylinder 211. During the movement of the outer box 1, the guide column 267 can slide inside the guide groove 268, and the rectangular sliding sleeve 269 slides on the surface of the rectangular slider 2610, ensuring the stability of the outer box 1 during vertical movement. This facilitates the outer box 1 rising and then suddenly falling when the coal slime accumulates inside the S-shaped material cylinder 211, assisting the coal slime in sliding inside the S-shaped material cylinder 211 under the action of vibration.
