Description
Technical Field
[0001] This utility model relates to the field of coal slag cleaning and dust suppression technology, specifically a boiler coal slag cleaning device with dust suppression function. Background Technology
[0002] A boiler is an energy conversion device, mainly used to convert incoming coal fuel into heat energy through combustion. This heat energy is then transferred to water or other working media in the boiler, turning it into steam or hot water. The steam generated in this process can be used to drive a turbine generator to produce electricity, or used as a heat source in industrial production and residential heating. After the coal fuel is burned, it forms ash, which is discharged from the ash discharge port at the bottom of the boiler.
[0003] Currently, boiler slag cleaning uses a conveyor belt method. Compared with manual slag cleaning, conveyor belt cleaning reduces the risk of workers being directly exposed to high temperatures and hazardous environments, improving work safety. In addition, the conveyor belt can operate in a closed system, reducing secondary pollution of the environment during the transportation of slag. However, a large amount of slag dust is generated during the conveying and cleaning process. The slag dust contains fine particulate matter. If these particles are inhaled, they may cause or aggravate respiratory diseases. Furthermore, if not handled properly, they may be spread to the surrounding environment by the wind, polluting soil and water sources and causing damage to the ecological environment.

[0025] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0026] Example
[0027] like Figures 1-6 As shown, a boiler slag cleaning device with dust suppression function includes: a cleaning box 1, a receiving hopper 101 installed on the top of the cleaning box 1, a collection box 102 installed on one side of the outer end of the cleaning box 1, and a cleaning assembly set inside the cleaning box 1, the cleaning assembly including: a conveyor table 2, a rotating roller 201, a stainless steel conveyor chain plate 202, a servo motor 203, a discharge port 204, a guide table 205 and a slag collection box 206, and a dust suppression assembly set outside the cleaning box 1 and the collection box 102, the dust suppression assembly including: a dust suppression box 3, a dust suction fan 301, a dust suction pipe 302, a water storage tank 303, a water pump 304, a water delivery pipe 305 and a dust suppression nozzle 306.
[0028] The cleaning box 1 is equipped with a conveyor platform 2. Inside the conveyor platform 2, a rotating roller 201 is rotatably connected via bearings. A stainless steel conveyor chain plate 202 is installed on the outside of the rotating roller 201. A servo motor 203 is installed on the outer end of the conveyor platform 2. One side of the outer end of the rotating roller 201 is connected to the output end of the servo motor 203. A discharge port 204 is opened on one side of the top of the collection box 102. The discharge port 204 is located on one side of the bottom of the stainless steel conveyor chain plate 202. A guide platform 205 is installed inside the collection box 102 at a position opposite to the discharge port 204. A slag collection box 206 is provided on one side of the guide platform 205.
[0029] When the cleaning box 1 is in use, the receiving hopper 101 at the top of the cleaning box 1 is aligned with the slag discharge port at the bottom of the boiler. The size of the receiving hopper 101 and the slag discharge port are the same, allowing the receiving hopper 101 to be installed and sealed to prevent leakage to the outside during the slag discharge process. After the coal fuel burns inside the boiler and forms slag, it will be discharged from the slag discharge port into the receiving hopper 101 and fall into the cleaning box 1. Since the stainless steel conveyor chain plate 202 is positioned opposite the receiving hopper 101, the slag can fall onto the stainless steel conveyor chain plate 202. At this time, the servo motor 203 is started, and the servo motor 203 drives the rotating roller 201 to move the stainless steel conveyor chain plate 202. The steel conveyor chain 202 rotates and operates, while the stainless steel conveyor chain 202 conveys the coal slag to the discharge port 204. That is, the coal slag falls from the stainless steel conveyor chain 202 to the discharge port 204 and enters the collection box 102. Then, it slides down through the guide platform 205 inside the collection box 102 to the coal slag collection box 206 for temporary storage and collection. This speeds up the cleaning of coal slag inside the boiler, reduces the risk of workers directly contacting high temperatures and hazardous environments, and improves work safety. In addition, the stainless steel conveyor chain 202 operates in a closed manner inside the cleaning box 1 and the collection box 102, reducing secondary pollution of the environment caused by coal slag during transportation.
[0030] Among them, baffles 207 are installed on both sides of the top of the conveyor platform 2, and the outside of the collection box 102 is provided with an opening 208 that is compatible with the slag collection box 206. When the slag falls onto the stainless steel conveyor chain plate 202 for conveying and cleaning, the baffles 207 can prevent the slag from falling out from both sides of the stainless steel conveyor chain plate 202, thus avoiding the accumulation of slag inside the cleaning box 1.
[0031] The collection box 102 is equipped with a dust suppression box 3 on the outside. A dust extraction fan 301 is installed on the top of the dust suppression box 3. Both the cleaning box 1 and the collection box 102 are equipped with a dust extraction pipe 302 connected to the dust extraction fan 301. A water storage tank 303 is provided on the outside of the dust suppression box 3. A water pump 304 is provided at the bottom of the inside of the water storage tank 303. A water supply pipe 305 is installed between the water pump 304 and the dust suppression box 3. A dust suppression nozzle 306 is installed at the bottom of the water supply pipe 305.
[0032] When cleaning coal slag inside the enclosed cleaning box 1 and collection box 102, the generated coal slag dust will be scattered inside the cleaning box 1 and collection box 102. At this time, the dust extraction fan 301 is started. The dust extraction fan 301 generates suction force on the dust extraction pipe 302, the cleaning box 1 and the collection box 102, drawing the generated dust into the dust extraction pipe 302 and discharging it into the dust suppression box 3. At the same time, the water pump 304 is started. The water pump 304 draws water from the dust suppression box 3 into the water supply pipe 305, and then delivers the water to the dust suppression nozzle 306. The dust suppression nozzle 306 sprays water mist downwards to remove the dust discharged into the dust suppression box 3, preventing workers from inhaling it and causing or aggravating respiratory diseases. It also prevents the dust from spreading with the wind into the surrounding environment and polluting water sources, thus improving ecological environmental protection.
[0033] The dust inlet end of the suction pipe 302 is threadedly connected to a debris-separating cover 4, and a debris-separating mesh 401 is installed at the bottom of the debris-separating cover 4. When the suction pipe 302 is in use, the debris-separating cover 4 is installed at the dust inlet end of the suction pipe 302. During the dust collection process of the cleaning box 1 and the collection box 102, the debris-separating mesh 401 at the bottom of the debris-separating cover 4 can prevent large particles of impurities from being sucked in, thus avoiding damage to the suction fan 301. However, dust can enter the suction pipe 302 through the debris-separating mesh 401, which facilitates the collection and treatment of coal slag dust.
[0034] The dust suppression box 3 has a filter screen plate 307 fixed inside. The filter screen plate 307 is located at the bottom of the dust suppression nozzle 306. The bottom of the filter screen plate 307 is provided with a water collection tank 308. The bottom of the water collection tank 308 is provided with a return pump 309. A return pipe 310 is installed between the return pump 309 and the water storage tank 303.
[0035] When the dust suppression nozzle 306 sprays water mist downwards to spray the dust entering the dust suppression box 3, the dust will clump together and fall onto the filter screen 307 after encountering the water mist. The filter screen 307 will block and collect the dust and impurities, while the sprayed water will fall from the filter screen 307 into the water collection tank 308 for collection. After the water in the water storage tank 303 is used up, the return pump 309 will be started to extract the water collected in the water collection tank 308 and transport it to the water storage tank 303 through the return pipe 310, so as to recycle and reuse the water and avoid water waste.
[0036] A sealing baffle is hinged to the outer side of the dust suppression box 3 and the filter screen 307. When dust and impurities accumulate on the filter screen 307, the sealing baffle can be opened to remove the filter screen 307 from the dust suppression box 3 for cleaning. After rinsing it with water, it can be put back into the dust suppression box 3 to prevent the mesh of the filter screen 307 from being blocked by dust and impurities and affecting normal use.
[0037] The water collection tank 308 is equipped with a drainage pump 311 at the bottom. The drainage pump 311 is equipped with a water outlet pipe 312 at the top. The water outlet pipe 312 passes through the dust suppression box 3 and extends to the outside of the water storage tank 303. After the water used for dust suppression by spraying coal slag dust is recycled and reused multiple times, the water becomes relatively dirty. After the water is collected inside the water collection tank 308, the drainage pump 311 is started to work. The drainage pump 311 pumps the water out and delivers it to the water outlet pipe 312. The water is discharged into the sewage pool through the water outlet pipe 312. The water storage tank 303 is equipped with a water inlet pipe at the top. After the water inside the water storage tank 303 is used up, water can be added to the water storage tank 303 through the water inlet pipe for later use.
[0038] The dust suppression box 3 has an exhaust pipe 313 installed on one side of the top. The top and bottom of the exhaust pipe 313 are equipped with dustproof fine mesh. After the coal slag dust discharged into the dust suppression box 3 is removed, the air inside the dust suppression box 3 can be discharged to the outside of the dust suppression box 3 through the exhaust pipe 313. When the exhaust pipe 313 is in use, the dustproof fine mesh can prevent the dust inside the dust suppression box 3 that has not been cleaned from being discharged from the exhaust pipe 313.
[0039] Working principle:
[0040] When the cleaning box 1 is in use, the receiving hopper 101 at the top of the cleaning box 1 is aligned with the slag discharge port at the bottom of the boiler. The size of the receiving hopper 101 and the slag discharge port are the same, allowing the receiving hopper 101 to be installed and sealed to prevent leakage to the outside during the slag discharge process. After the coal fuel burns inside the boiler and forms slag, it will be discharged from the slag discharge port into the receiving hopper 101 and fall into the cleaning box 1. Since the stainless steel conveyor chain plate 202 is positioned opposite the receiving hopper 101, the slag can fall onto the stainless steel conveyor chain plate 202. At this time, the servo motor 203 is started, and the servo motor 203 drives the rotating roller 201 to move the stainless steel conveyor chain plate 202. The steel conveyor chain 202 rotates and operates, while the stainless steel conveyor chain 202 conveys the coal slag to the discharge port 204. That is, the coal slag falls from the stainless steel conveyor chain 202 to the discharge port 204 and enters the collection box 102. Then, it slides down through the guide platform 205 inside the collection box 102 to the coal slag collection box 206 for temporary storage and collection. This speeds up the cleaning of coal slag inside the boiler, reduces the risk of workers directly contacting high temperatures and hazardous environments, and improves work safety. In addition, the stainless steel conveyor chain 202 operates in a closed manner inside the cleaning box 1 and the collection box 102, reducing secondary pollution of the environment caused by coal slag during transportation.
[0041] When cleaning coal slag inside the enclosed cleaning box 1 and collection box 102, the generated coal slag dust will be scattered inside the cleaning box 1 and collection box 102. At this time, the dust extraction fan 301 is started. The dust extraction fan 301 generates suction force on the dust extraction pipe 302, the cleaning box 1 and the collection box 102, drawing the generated dust into the dust extraction pipe 302 and discharging it into the dust suppression box 3. At the same time, the water pump 304 is started. The water pump 304 draws water from the dust suppression box 3 into the water supply pipe 305, and then delivers the water to the dust suppression nozzle 306. The dust suppression nozzle 306 sprays water mist downwards to remove the dust discharged into the dust suppression box 3, preventing workers from inhaling it and causing or aggravating respiratory diseases. It also prevents the dust from spreading with the wind into the surrounding environment and polluting water sources, thus improving ecological environmental protection.
[0042] When the dust suppression nozzle 306 sprays water mist downwards to spray the dust entering the dust suppression box 3, the dust will clump together and fall onto the filter screen 307 after encountering the water mist. The filter screen 307 will block and collect the dust and impurities, while the sprayed water will fall from the filter screen 307 into the water collection tank 308 for collection. After the water in the water storage tank 303 is used up, the return pump 309 will be started to extract the water collected in the water collection tank 308 and transport it to the water storage tank 303 through the return pipe 310, so as to recycle and reuse the water and avoid water waste.
