[0001] The utility model belongs to the technical field of boilers, in particular to a boiler ash cleaning device. Background Art

[0002] A boiler is an energy conversion device that converts heat energy into electrical energy or other energy by adding coal and other combustible materials into the boiler. When using coal as raw materials, the combustion of coal will leave a lot of dust in the boiler. At this time, boiler ash cleaning equipment is needed to remove the dust.

[0003] When removing dust adhering to the inner wall of the boiler, the existing boiler ash cleaning equipment usually uses a scraper to scrape off the dust adhering to the inner wall of the boiler. During long-term use and observation, it is found that when the existing boiler ash cleaning equipment scrapes the dust adhering to the inner wall of the boiler, the dust is light in weight and more dust will be generated when scraping it off, causing problems of environmental pollution and endangering personnel health.

[0004] To this end, the utility model provides a boiler ash cleaning device. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Specific examples are given below.

[0025] like Figure 1 to Figure 2As shown, a boiler ash cleaning device described in an embodiment of the utility model comprises a boiler body 1; a motor 11 is fixedly connected to the top of the boiler body 1; a rotating shaft 12 is fixedly connected to the output end of the motor 11; a pair of scrapers 13 are fixedly connected to the side wall of the rotating shaft 12; a bottom plate 14 is fixedly connected to the bottom of the boiler body 1; a purification box 15 is connected to the top of the motor 11; an air pump 16 is connected to the side wall of the purification box 15; the purification box 15 and the air pump 16 are both fixedly connected to the top of the bottom plate 14; an air inlet 17 is connected to the side wall of the boiler body 1; when working, the motor 11 can be started to drive the rotating shaft 12 and the scraper 13 to rotate simultaneously, and at this time, the scraper 13 rotates and contacts the inner wall of the boiler body 1 The scraper 13 can be used to scrape the dust adhering to the inner wall of the boiler after the coal is burned. At the same time, starting the air pump 16 can allow the air flow to enter the boiler body 1 from the air inlet 17 and then enter the liquid storage tank 51 and then be discharged through the air pump 16. When the air flow passes through the boiler body 1, the dust generated by the scraped dust can be brought out. When passing through the purification box 15, the dust-mixed air flow will be purified. In this step, the motor 11 is set to drive the scraper 13 to scrape the inner wall of the boiler body 1 to scrape off the adhered ash. At the same time, the air pump 16 draws the generated dust out of the boiler body 1 and purifies it through the purification box 15, which can reduce the pollution and health hazards caused by the dust generated when cleaning the ash.

[0026] like Figure 2 As shown, a fixed block 22 is fixedly connected to the end of the rotating shaft 12; a pair of connecting plates 2 are fixedly connected to the side wall of the fixing block 22; a plurality of bristles 21 are fixedly connected to the side wall of the connecting plate 2; during operation, the rotating shaft 12 rotates to drive the connecting plate 2 and the bristles 21 to rotate at the same time. At this time, the bristles 21 are in contact with the inner wall of the boiler body 1 and can clean it during rotation, which can reduce the relatively fine dust remaining after the scraper 13 scrapes the boiler body 1. In this step, the rotating shaft 12 is set to drive the bristles 21 and the fixed block 22 to rotate so as to clean the inner wall of the boiler body 1, which can reduce the relatively small dust remaining after the scraper 13 scrapes the inner wall of the boiler body 1. The arc-shaped structure of the bristles 21 can fit the inner wall of the boiler body 1 to increase the contact surface with the inner wall of the boiler body 1, so as to improve the cleaning effect.

[0027] like Figure 3 As shown, a pair of cylinders 3 are fixedly connected to the side wall of the boiler body 1; the ends of the pair of cylinders 3 are fixedly connected to the first impact block 31; during operation, the reciprocating motion of the cylinder 3 is started to drive the first impact block 31 to reciprocate, and at this time, the boiler body 1 vibrates when the first impact block 31 repeatedly knocks on the side wall of the boiler body 1, and the dust adhering to the inner wall of the boiler body 1 can be shaken off. In this step, the cylinder 3 is set to drive the first impact block 31 to move back and forth to repeatedly knock on the side wall of the boiler body 1, and the boiler body 1 vibrates through the knocking and the dust adhering to the inner wall of the boiler body 1 is shaken off, so as to improve the effect of cleaning the ash.

[0028] like Figure 4 As shown, a pair of elastic rods 4 are fixedly connected to the side wall of the first impact block 31; a second impact block 41 is fixedly connected to the end of the elastic rod 4; during operation, when the first impact block 31 moves back and forth, it will drive the elastic rod 4 and the second impact block 41 to move back and forth at the same time, and the elastic rod 4 will bend and deform when moving. At this time, the second impact block 41 can be repeatedly knocked on the side wall of the boiler body 1 to vibrate the boiler body 1 and vibrate off the ash adhered to the inner wall of the boiler body 1. In this step, by setting the first impact block 31 to connect the elastic rod 4 and the second impact block 41, the elastic rod 4 can be bent and deformed when moving back and forth, thereby driving the second impact block 41 to knock on the side wall of the boiler body 1, which can increase the range of knocking on the side wall of the boiler body 1 to improve the effect of vibrating off the ash.

[0029] like Figure 2 As shown, the top of the boiler body 1 is connected with a liquid inlet pipe 5; the side wall of the rotating shaft 12 is fixedly connected with a liquid storage tank 51; the side wall of the liquid storage tank 51 is provided with a plurality of liquid outlet holes 52; during operation, the external water source is connected to the liquid inlet pipe 5. When water enters the boiler body 1, it will flow into the liquid storage tank 51. When the rotating shaft 12 rotates, it will drive the liquid storage tank 51 to rotate. At this time, the water in the liquid storage tank 51 will flow out from the liquid outlet holes 52, and with the centrifugal force of the rotation, it will be thrown to the inner wall of the boiler body 1 for cleaning. In this step, by setting the rotating shaft 12 to drive the liquid storage tank 51 to rotate, the water flowing into the liquid storage tank 51 can be thrown from the liquid outlet holes 52 to the inner wall of the boiler body 1 for cleaning, and the ash adhering to the inner wall of the boiler body 1 will be cleaned to reduce the residual ash inside the boiler body 1.

[0030] like Figure 1 and Figure 5 As shown, a collecting box 6 is fixedly connected to the top of the bottom plate 14; a filter screen 61 is detachably installed on the inner wall of the collecting box 6; a drain pipe 62 is connected to the side wall of the collecting box 6; during operation, when the cleaned sewage flows out from the bottom of the boiler body 1, it will enter the collecting box 6 below, and when passing through the filter screen 61, the sewage will be filtered to filter out part of the ash, and the filtered sewage will be discharged from the drain pipe 62. In this step, by setting the collecting box 6 connected to the filter screen 61, the cleaned sewage can be filtered, and part of the ash in the sewage can be filtered out, so as to reduce the pollution to the environment when the sewage is discharged.

[0031] like Figure 3 As shown, the side walls of the first impact block 31 and the second impact block 41 are fixedly connected with a buffer pad 7; during operation, when the first impact block 31 and the second impact block 41 knock on the side wall of the boiler body 1, the contact between the buffer pad 7 and the side wall of the boiler body 1 can reduce the damage caused by the collision between the first impact block 31 and the second impact block 41 and the side wall of the boiler body 1. This step can reduce the damage caused by the impact force when the first impact block 31 and the second impact block 41 knock on the side wall of the boiler body 1 by setting the buffer pad 7, which plays a protective role.

[0032] Working principle: When working, the motor 11 is started to drive the rotating shaft 12 and the scraper 13 to rotate at the same time. At this time, the scraper 13 contacts the inner wall of the boiler body 1 when rotating to scrape and sweep away the dust adhering to the inner wall of the boiler after the coal is burned. At the same time, the air pump 16 is started to allow the air flow to enter the boiler body 1 from the air inlet 17 and then enter the liquid storage tank 51 and then be discharged through the air pump 16. When the air flow passes through the boiler body 1, the dust generated by the scraped dust can be taken out, and the dust-mixed air flow will be purified when passing through the purification box 15. When the rotating shaft 12 rotates, the connecting plate 2 and the bristles 21 are driven to rotate simultaneously. At this time, the bristles 21 are in contact with the inner wall of the boiler body 1 and can clean it during rotation, which can reduce the relatively fine dust remaining after the scraper 13 scrapes the boiler body 1. The reciprocating motion of the cylinder 3 can drive the first impact block 31 to reciprocate. At this time, the first impact block 31 can repeatedly knock the side wall of the boiler body 1 to generate vibration of the boiler body 1, which can shake off the dust adhering to the inner wall of the boiler body 1. When the first impact block 31 reciprocates, the boiler body 1 will vibrate. When the rotating shaft 12 rotates, the liquid storage tank 51 is driven to rotate. At this time, the water in the liquid storage tank 51 flows out from the liquid outlet 52. As the rotating shaft 12 rotates, the liquid storage tank 51 is driven to rotate. At this time, the water in the liquid storage tank 51 flows out from the liquid outlet 52. The centrifugal force will throw it to the inner wall of the boiler body 1 for cleaning. When the cleaned sewage flows out from the bottom of the boiler body 1, it will enter the collection box 6 below. When passing through the filter 61, the sewage will be filtered to filter out part of the ash. The filtered sewage is discharged from the drain pipe 62. When the first impact block 31 and the second impact block 41 knock on the side wall of the boiler body 1, the buffer pad 7 contacts the side wall of the boiler body 1 to reduce the damage caused by the collision between the first impact block 31 and the second impact block 41 and the side wall of the boiler body 1.
