[0041] Please refer to Figures 1 to 4 , and a description is now given of the air supply pipeline for the grate cooler provided by the present utility model. The air supply pipeline for the grate cooler includes a pipe body 10, a cleaning chamber, a first driving assembly, a filtering assembly, a cleaning assembly, and a dust collection chamber 24. The interior of the pipe body 10 is used for cold air to flow through; the cleaning chamber includes a first chamber body 21 and a second chamber body 22. The first chamber body 21 is arranged on one side of the pipe body 10, connected to and communicating with the pipe body 10; the second chamber body 22 is arranged on the other side of the pipe body 10, connected to and communicating with the pipe body 10; a first ash discharge port is provided at the bottom of the end of the first chamber body 21 away from the pipe body 10; the first driving assembly includes a first motor assembly 31, a first driving roller 32, and a second driving roller 33. The first driving roller 32 and the second driving roller 33 are respectively arranged in the first chamber body 21 and the second chamber body 22, and are respectively connected to the first chamber body 21 and the second chamber body 22. The power output end of the first motor assembly 31 is connected to the first driving roller 32 or the second driving roller; the filtering assembly is connected end to end, and both ends are respectively sleeved on the first driving roller 32 and the second driving roller; the cleaning assembly includes a cleaning mechanism and a second driving assembly. The cleaning mechanism includes a roller brush 51. The roller brush 51 is arranged in the first chamber body 21, connected to the first chamber body 21, and used for brushing the surface of the filtering assembly; the power output end of the second driving assembly is connected to the roller brush 51 to drive the roller brush 51 to rotate; the dust collection chamber 24 is arranged below the first chamber body 21, connected to and communicating with the first ash discharge port, and used for collecting dust.

[0042] Specifically, the first motor assembly 31 is connected to the second chamber body 22, and the power output end is connected to the second driving roller to drive the second driving roller to rotate.

[0043] The beneficial effects of the air supply pipeline of the grate cooler provided by the present utility model are as follows: Compared with the prior art, in the air supply pipeline of the grate cooler provided by the present utility model, a roller brush 51 is provided in the first bin 21 on one side of the pipe body 10, and the filtering component of the pipe body 10 is driven by the first driving assembly to continuously pass through the roller brush 51, so that the whole filtering component is brushed by the roller brush 51. The dust brushed off falls into the dust collection bin 24 through the first ash discharge port, and thus the filtering component is continuously brushed during the working process, effectively avoiding the blockage of the filtering component and ensuring the air supply.

[0044] As Figure 2 and Figure 4 shown, in a specific embodiment of the air supply pipeline of the grate cooler provided by the embodiment of the present utility model, the filtering component includes a filter screen 42 and two belts 41. The two belts 41 are sleeved on the first driving roller 32 and the second driving roller at intervals; the filter screen 42 is arranged between the two belts 41 and is respectively connected to the two belts 41.

[0045] It should be noted that the mechanical properties of the filter screen 42 are usually poor. Therefore, two belts 41 are arranged on both sides of the filter screen 42 to bear the tension through the belts 41 and prevent the filter screen 42 from being damaged due to excessive force.

[0046] As Figure 3 shown, in a specific embodiment of the air supply pipeline of the grate cooler provided by the embodiment of the present utility model, the cleaning mechanism further includes a scraper 52. The scraper 52 is arranged on the side of the roller brush 51 facing away from the filtering component, with one end connected to the first bin 21 and the other end interfering with the bristles of the roller brush 51.

[0047] It should be noted that during the process of the roller brush 51 brushing the filtering component, some fluff, dust, etc. will also adhere to the roller brush 51. Therefore, a scraper 52 that interferes with the bristles of the roller brush 51 is provided to continuously scrape off the fluff, dust, etc. on the roller brush 51 during the working process.

[0048] Specifically, the scraper 52 is provided with comb teeth to scrape off the fluff, dust, etc. adhering to the roller brush 51 more effectively.

[0049] As Figure 3 shown, in a specific embodiment of the air supply pipeline of the grate cooler provided by the embodiment of the present utility model, the cleaning assembly is provided with two cleaning mechanisms, and the two cleaning mechanisms are symmetrically arranged on the upper and lower sides of the filtering component to effectively improve the cleaning efficiency and ensure the cleanliness of the filtering component.

[0050] As Figure 1 and Figure 2As shown, in a specific implementation of the air supply pipeline of the grate cooler provided by the embodiment of the present utility model, the second drive assembly includes a main gear 54, two sub-gears 53 and a second motor assembly 55. The two sub-gears 53 are respectively connected to the roller brushes 51 in the two cleaning mechanisms, and the two sub-gears 53 mesh with each other; the main gear 54 meshes with the sub-gear 53; the second motor assembly 55 is connected to the first bin 21, and the power output end is connected to the main gear 54 to drive the main gear 54 to rotate.

[0051] It should be noted that during operation, the second motor assembly 55 drives the main gear 54 to rotate, thereby driving the two sub-gears 53 to rotate, so that the positions where the two roller brushes 51 contact the filter assembly rotate away from the pipe body 10.

[0052] As Figure 1 and Figure 3 As shown, in a specific implementation of the air supply pipeline of the grate cooler provided by the embodiment of the present utility model, a connecting pipe 23 is provided between the first bin 21 and the dust collection bin 24. The upper opening of the connecting pipe 23 is larger than the lower opening, and the upper end of the connecting pipe 23 is connected to the first ash discharge port, and the lower end is connected to and communicates with the dust collection bin 24.

[0053] It should be noted that the connecting pipe 23 is set with the upper opening larger than the lower opening. On the one hand, it is convenient for the dust in the first bin 21 to enter the dust collection bin 24, and on the other hand, it effectively reduces the situation that the dust in the dust collection bin 24 reversely enters the first bin 21.

[0054] As Figure 1 and Figure 3 As shown, in a specific implementation of the air supply pipeline of the grate cooler provided by the embodiment of the present utility model, the top of the dust collection bin 24 is arranged in a V shape, and the connecting pipe 23 is connected to the lowest part of the top of the dust collection bin 24, effectively preventing the dust in the dust collection bin 24 from rising along the side wall of the dust collection bin 24 and entering the first bin 21.

[0055] As Figure 1 and Figure 3 As shown, in a specific implementation of the air supply pipeline of the grate cooler provided by the embodiment of the present utility model, it further includes a star-shaped discharge valve 25. A second ash discharge port is provided at the bottom of the dust collection bin 24, and the second ash discharge port is connected to the star-shaped discharge valve 25 to maintain the sealing of the dust collection bin 24 during discharging, avoid air leakage, and ensure the air pressure.

[0056] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
