Description

Technical Field

[0001] The invention belongs to the technical field of slag collection, and in particular relates to a slag collection device for a thermal power generation boiler. Background Art

[0002] Thermal power boilers are devices that burn fuel to generate heat energy. This heat energy is used to heat water, generate steam, and drive steam turbines to generate electricity. Thermal power generation is one of the important ways of modern electricity production, especially in the world, it still accounts for a large proportion. The working principle of thermal power boilers mainly includes three steps: combustion, heat exchange, and steam generation. First, the fuel is mixed with air in the furnace of the boiler and then burned to produce high-temperature gas. Then, the heat in the furnace is transferred to the water through the water pipes of the boiler. The water becomes high-pressure steam during the heating process. Finally, the steam is sent to the turbine to drive the turbine to rotate and drive the generator to generate electricity.

[0003] Slag is a solid waste produced in the process of thermal power generation. It is mainly composed of unburned fuel, minerals and other combustion products. When coal is burned, the ash and some chemicals in the coal will form slag, which is usually deposited at the bottom of the boiler. The treatment and utilization of slag is an important link in the thermal power generation industry. Reasonable management can reduce environmental pollution.

[0049] A feed inlet 4 is provided at one end of the device body 1, a water injection port 5 is provided at the top of the device body 1, a water storage chamber 8 connected with the water injection port 5 is provided in the device body 1, a liquid discharge port 6 is provided at one end of the device body 1, a discharge port 13 is provided on the side of the device body 1, a motor protection box 11 is installed at one end of the device body 1, the motor protection box 11 is adapted to the second motor 210, the conveying plate 201 is adapted to the first crushing roller 206, the first crushing roller 206 is adapted to the atomizing nozzle 212, a piston cover 7 is installed at one end of the water injection port 5, a first water outlet 9 is provided at one end of the water storage chamber 8, the feed inlet 4 is adapted to the first water outlet 9, a second water outlet 10 is provided at one end of the water storage chamber 8, and the second water outlet 10 is connected to one end of the liquid spray box 211.

[0050] When the slag needs to be collected, the slag needs to be cooled before collection. The slag is poured into the device body 1 through the feed port 4, the piston cover 7 on the top of the device body 1 is opened, and the water injection device is inserted through the water injection port 5. Water is continuously injected into the water storage chamber 8. When the slag falls into the feed port 4, water is continuously discharged from the first water outlet 9 to preliminarily cool the surface of the slag. When the slag falls into the conveying plate 201, the first motor 205 is started to drive the connecting shaft 203 to rotate, and the other connecting shaft 203 is rotated by the belt 204, thereby driving the two transmissions. The worm 202 rotates to transport the slag. The continuous rotation and transmission of the transmission worm 202 prevents the slag from accumulating in the feed port 4. When the slag is transported to the other end of the conveying plate 201, the second motor 210 is started to drive the first gear 208 to rotate. The first gear 208 drives the meshing second gear 209 to rotate in the opposite direction, thereby causing the first crushing roller 206 and the second crushing roller 207 to rotate relative to each other. The tooth blocks on the first crushing roller 206 and the second crushing roller 207 squeeze and crush the slag to disperse it into small pieces, and disperse the inside of the slag to facilitate continued cooling.

[0051] When the slag fragments are transmitted through the first crushing roller 206, the water in the water storage chamber 8 enters the spray box 211 through the second water outlet 10, and is sprayed on one end of the first crushing roller 206 through multiple atomizing nozzles 212 at one end of the spray box 211. The water mist can cool down and remove dust, and further cool down the fallen slag fragments, so that the slag is completely cooled down to facilitate subsequent collection and treatment. When the slag is cooled down, some waste liquid will be generated. After falling, the waste liquid is guided by the inclined surface of the conveyor belt 12 and flows into one end of the device body 1. The waste liquid is discharged through the drain port 6. The slag is initially cooled down through the first water outlet 9 and the slag fragments are further cooled down by the atomizing nozzle 212, so that the inside of the slag can be completely cooled down, thereby improving the cooling effect of the slag, preventing the slag from overheating and affecting the service life of the device and the difficulty of collection, and improving the efficiency of slag collection.

[0052] Example 2: Figure 3-10 As shown, in order to screen and collect the fragments of the slag, the filtering mechanism 3 includes a symmetrical limit groove 301 opened in the device body 1, a limit block 302 is slidably installed in the limit groove 301, a screen frame 303 is installed at one end of the limit block 302, a spring 304 is provided in the limit groove 301, a motor protection shell 309 is installed at the bottom of the conveying plate 201, a third motor 310 is installed in the motor protection shell 309, a cam 311 is installed at one end of the third motor 310, one end of the spring 304 is installed on the inner wall of the limit groove 301, and the other end of the spring 304 is installed on the limit block 302, a conveyor belt 12 is installed in the device body 1, the conveyor belt 12 is adapted to the screen frame 303, and one end of the conveyor belt 12 is connected to the discharge port 13.

[0053] The slag fragments after cooling fall on the screen frame 303, and continuously fall on the conveyor belt 12 through the filter holes on the screen frame 303. The processed slag is discharged through the discharge port 13 for collection through the conveyor belt 12. When the slag falls on the screen frame 303, blockage may occur. While the slag fragments fall, the third motor 310 is started to adjust the cam 311 to rotate. When the cam 311 rotates, one end of the cam 311 protrudes, and the protruding part can be against the side of the screen frame 303. When rotating, the protruding part intermittently squeezes the screen frame 303. When the screen frame 303 is squeezed, the limit block 302 is driven to slide in the limit groove 301, and the spring 304 is compressed. When the protruding end turns to the other side, the spring 304 will rebound and drive the limit block 302 to return, so that the screen frame 303 can move left and right, producing an oscillation effect, so that the slag fragments that may be accumulated on the screen frame 303 are sieved and dropped. The remaining features are the same as those in Example 1.

[0054] Embodiment 3:

[0055] like Figure 6-8 As shown, after screening for a period of time, the screen frame 303 needs to be cleaned, a connecting strip 305 is installed at one end of the screen frame 303, and two fixing bolts 306 are installed at one end of the connecting strip 305, a pull plate 307 is installed on the side of the device body 1, and a handle 308 is installed at one end of the pull plate 307. When too much slag is collected, some debris in the slag may adhere to the screen frame 303, and the screen frame 303 needs to be cleaned and maintained regularly, and the pull plate 307 on the side of the device body 1 is opened by the handle 308, and the two fixing bolts 306 on the side of the screen frame 303 are rotated through the opening of the pull plate 307 to separate the screen frame 303, and the connecting strip 305 at one end is removed, and the debris on the surface of the screen frame 303 can be scraped off with a scraper or a brush to increase the service life of the screen frame 303. After cleaning, the connecting strip 305 is tightened by the fixing bolts 306 and reinstalled on the screen frame 303. The remaining features are the same as those in Example 1.

[0056] The working principle of the slag collection device for a thermal power generation boiler according to the embodiment of the present invention is as follows:

[0057] When it is necessary to collect the slag, it is necessary to cool the slag before collecting, pour the slag into the device body 1 through the feed port 4, open the piston cover 7 on the top of the device body 1, insert the water injection equipment through the water injection port 5, and continuously inject water into the water storage chamber 8. When the slag falls into the feed port 4, water is continuously discharged from the first water outlet 9 to preliminarily cool the surface of the slag. When the slag falls into the conveying plate 201, start the first motor 205 to drive the connecting shaft 203 to rotate, and mobilize the other connecting shaft 203 to rotate through the belt 204, thereby driving the two transmission worms 202 to rotate, and the slag is transmitted through the continuous rotation of the transmission worm 202 to prevent the slag from accumulating in the feed port 4.

[0058] When the slag is transferred to the other end of the conveying plate 201, the second motor 210 is started to drive the first gear 208 to rotate, and the first gear 208 drives the meshing second gear 209 to rotate in the opposite direction, thereby making the first crushing roller 206 and the second crushing roller 207 rotate relative to each other, and the teeth on the first crushing roller 206 and the second crushing roller 207 squeeze and crush the slag to disperse the slag into small pieces, and disperse the inside of the slag to facilitate further cooling.

[0059] When the slag fragments are transmitted through the first crushing roller 206, the water in the water storage chamber 8 enters the spray box 211 through the second water outlet 10, and is sprayed on one end of the first crushing roller 206 through multiple atomizing nozzles 212 at one end of the spray box 211. The water mist can cool down and remove dust, further cool down the fallen slag fragments, and completely cool down the slag for subsequent collection and treatment.

[0060] The slag fragments after cooling fall on the screen frame 303, and continuously fall on the conveyor belt 12 through the filter holes on the screen frame 303. The processed slag is discharged through the discharge port 13 for collection through the conveyor belt 12. When the slag falls on the screen frame 303, blockage may occur. While the slag fragments fall, the third motor 310 is started to mobilize the cam 311 to rotate. When the cam 311 rotates, one end of the cam 311 protrudes, and the protruding part can be against the side of the screen frame 303. When rotating, the protruding part intermittently squeezes the screen frame 303. When the screen frame 303 is squeezed, it will drive the limit block 302 to slide in the limit groove 301, and the spring 304 will be compressed. When the protruding end turns to the other side, the spring 304 will rebound and drive the limit block 302 to return, so that the screen frame 303 can move left and right, resulting in an oscillation effect, so that the slag fragments that may be accumulated on the screen frame 303 are sieved and dropped.

[0061] When too much slag is collected, some debris in the slag may adhere to the screen frame 303, and the screen frame 303 needs to be cleaned and maintained regularly. The pull plate 307 on the side of the device body 1 is opened through the handle 308. Through the opening of the pull plate 307, the two fixing bolts 306 on the side of the screen frame 303 are rotated to separate the screen frame 303, and the connecting strip 305 at one end is removed. The debris on the surface of the screen frame 303 can be scraped off with a scraper or a brush to increase the service life of the screen frame 303. After the cleaning is completed, the connecting strip 305 is After being tightened by fixing bolts 306, it is reinstalled on the screen frame 303. When the slag is cooled, some waste liquid will be generated. After falling, the waste liquid is guided by the inclined surface of the conveyor belt 12 and flows into one end of the device body 1. The waste liquid is discharged through the drain port 6. The slag is initially cooled by the first water outlet 9 and the slag fragments are further cooled by the atomizing nozzle 212, so that the inside of the slag can be completely cooled, thereby improving the cooling effect of the slag, preventing the slag from overheating and affecting the service life of the device and the difficulty of collection, and improving the efficiency of slag collection.
