The energy input to the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carriers with a certain amount of thermal energy. The combustion of fuel in the mechatronic boiler will produce ash. A chain scraper slag remover is used to discharge and transport the ash, which is convenient for cleaning.

[0003] The existing slag removers have the following main drawbacks during use: dust will occur during slag removal, and these high-temperature dusts will float in the air, which can easily cause damage to the health of workers. In addition, the slag discharge port of the existing slag remover is easily blocked, mainly because some slag is too large and stuck at the slag discharge port. Therefore, there is room for improvement. Utility Model Content

[0015] 1. In the utility model, a first oblique plate is fixed on the inner wall of the cylinder, and a spray piece is installed on the inner wall of the other side of the cylinder. When working, the chain scraper scrapes the slag onto the first oblique plate. At this time, the spray piece sprays the slag on the first oblique plate, which can reduce the temperature of the slag and have a good dust suppression effect, thereby reducing the dust content in the air in the cylinder. At the same time, the cylinder is sealed, and an air outlet duct is opened on one side of the cylinder, an exhaust piece is installed on the air outlet duct, and an annular filter is installed in the air outlet duct and fixed by the cover body. When working, the exhaust fan works to draw out the high-temperature dust-containing air in the inner cavity of the cylinder. When the high-temperature dust-containing air passes through the annular filter, the annular filter filters the dust therein, and the filtered air is discharged through the exhaust piece, which can effectively prevent the slag dust from drifting into the external environment, thereby increasing the practical performance. In addition, the cover body is threadedly connected, which makes the annular filter easy to install and disassemble.

It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0026] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0027] Embodiment 1:

[0028] Combination Figure 1-4 As shown, this embodiment provides a suspended coal-fired boiler room slag remover, including: a main body module 100, a dust reduction module 200 and a crushing module 300.

[0029] Among them, the main module 100 includes a body 110, a slag inlet 120 installed on one side of the body 110, and a chain scraper 130 installed in the inner cavity of the body 110. The body 110 is used to install other components. The slag inlet 120 is connected to the coal-fired boiler to facilitate the slag after combustion of the coal-fired boiler to enter the inner cavity of the body 110 through the slag inlet 120. The chain scraper 130 is used to scrape the slag in the inner cavity of the body 110 into the cylinder 210 to prevent it from accumulating near the slag inlet 120.

[0030] The dust reduction module 200 is installed on one side of the body 110, and is used to cool and dust the slag. It includes a cylinder 210 fixed on one side of the body 110, a slag outlet 220 installed at the bottom end of the cylinder 210, a first inclined plate 230 installed on the inner wall of the cylinder 210, a spray piece 240 installed on the inner wall of the cylinder 210 and facing the first inclined plate 230, an air outlet duct 250 fixed on one side of the cylinder 210 and connected to the inner cavity of the cylinder 210, an annular seat 260 fixed on the inner wall of the air outlet duct 250, a cover body 270 installed at one end of the air outlet duct 250 by threaded connection, an annular filter screen 280 with two ends respectively embedded in the cover body 270 and the annular seat 260, and an exhaust fan 292 installed on the air outlet duct 250 and connected to the air outlet duct 250.

[0031] The cylinder 210 is rectangular and is suspended on the wall by a bracket, which saves space near the slag outlet 220 and facilitates the forklift to enter the bottom of the slag outlet 220 to perform operations. The chain scraper 130 extends into the inner cavity of the cylinder 210 to facilitate scraping the slag into the cylinder 210. The first inclined plate 230 is fixed on the inner wall of the cylinder 210 to evenly distribute the slag when it enters the cylinder 210, which facilitates spraying and increases the spraying effect.

[0032] The spraying member 240 is used for spraying the slag, and includes a base 241 fixed on the inner wall of the cylinder 210, a plurality of nozzles 242 installed in an array on the base 241, and a water inlet pipe 243 installed on one side of the base 241 and extending out of the cylinder 210. The surface of the base 241 away from the inner wall of the cylinder 210 is inclined and faces the first inclined plate 230, and is used for installing the nozzle 242 and making the nozzle 242 face the first inclined plate 230. The water inlet pipe 243 is connected to the nozzle 242, and is used for delivering clean water into the nozzle 242 for spraying, so as to cool and reduce dust on the slag on the surface of the first inclined plate 230.

[0033] The air outlet duct 250 is connected to the inner cavity of the cylinder 210, and the annular seat 260 is fixed on the inner wall of the air outlet duct 250, and is used to fix one end of the annular filter 280. An internal thread is provided on the inner wall of the end of the air outlet duct 250, and an external thread is provided on the outer surface of the cover body 270, and the two are meshed with each other, which facilitates the installation and disassembly of the cover body 270, that is, it is convenient to replace the annular filter 280, which increases the convenience of use.

[0034] One end of the annular filter 280 is embedded in the cover 270, and the other end is embedded in the annular seat 260, so that when the high-temperature dusty air in the cylinder 210 passes through, the dust therein can be filtered to prevent the dusty air from drifting into the external environment.

[0035] The exhaust member 290 is used to exhaust the air in the cylinder 210 to prevent the inner temperature of the cylinder 210 from being too high. The exhaust member 290 includes an exhaust duct 291 whose end is connected to the air outlet duct 250 and an exhaust fan 292 installed on the inner wall of the exhaust duct 291. The exhaust duct 291 is used to install the exhaust fan 292, and the exhaust fan 292 is used to exhaust the air in the cylinder 210 to the outside.

[0036] The crushing module 300 is used to crush large pieces of slag, and includes a second inclined plate 310 fixed to the inner wall of the cylinder 210 and a crushing member 320 installed on the second inclined plate 310 .

[0037] The second oblique plate 310 is located below the first oblique plate 230 and is used to install a crushing piece 320. The crushing piece 320 includes a rotating shaft 321 rotatably installed in the second oblique plate 310, a plurality of cutter discs 322 fixedly sleeved on the rotating shaft 321, and a motor 323 installed on the outer surface of the cylinder 210 and fixedly connected to the end of the rotating shaft 321. The second oblique plate 310 is provided with a plurality of rectangular holes 311 in an array, and the cutter disc 322 is arranged in the rectangular hole 311. When a large piece of slag passes by, the motor 323 drives the rotating shaft 321 to rotate, and the rotation of the rotating shaft 321 drives the cutter disc 322 to rotate, so as to crush the large piece of slag to prevent it from blocking the slag outlet 220.

[0038] The working principle and use process of the utility model are as follows: when in use, the slag filtered by the coal falls into the inner cavity of the machine body 110 through the slag inlet 120, at which time the chain scraper 130 is started to scrape the slag in the inner cavity of the machine body 110 into the cylinder 210, and when the furnace body enters the cylinder 210, it flows along the first inclined plate 230, and at this time, clean water is sent to the nozzle 242 through the water inlet pipe 243, and sprayed to the slag on the surface of the first inclined plate 230 through the nozzle 242, cooling it while avoiding dust generation, and at the same time the exhaust fan 292 is started to discharge the air in the inner cavity of the cylinder 210 to the outside. When the high-temperature dusty air passes through the annular filter 280, the annular filter 280 filters the dust therein, and the filtered air is discharged through the exhaust piece 290, which can effectively prevent the slag dust from drifting into the external environment. When the sprayed slag falls onto the second oblique plate 310 along the first oblique plate 230, it moves along the second oblique plate 310. At this time, the motor 323 drives the rotating shaft 321 to rotate, and the rotation of the rotating shaft 321 drives the cutter disc 322 to rotate. As the cutter disc 322 rotates, the large pieces of slag passing through the second oblique plate 310 are crushed to prevent it from clogging the slag outlet 220.

[0039] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
