Description

Technical Field

[0001] This utility model relates to the field of anti-clogging technology for feeders, and in particular to an anti-clogging device for pulverized coal feeders. Background Technology

[0002] Pulverized coal is a fine particulate matter formed after coal is crushed, typically with a particle size between 0.02 mm and 1 mm. A pulverized coal feeder is a key device used to transport pulverized coal from storage equipment (such as a pulverized coal silo) to combustion equipment (such as a boiler). However, most current anti-clogging devices rely on vibration to break the cohesion between pulverized coal particles and prevent clogging. But for some wetter pulverized coal particles, strong adhesion can easily form, and ordinary vibration may not provide enough energy to break up the agglomerated coal particles, resulting in poor anti-clogging effectiveness. Therefore, improvements are urgently needed. Utility Model Content

[0055] The feed trough plate 9 is fixedly installed on the feed box 3; it is used to pour in pulverized coal.

[0056] An inclined plate 10 is disposed on the feed trough plate 9 and fixedly connected to the feed trough plate 9. It is used to provide a direction for the coal powder poured into the feed trough plate 9 to move, so that the coal powder enters the discharge box 3 through the feed inlet 4.

[0057] The first motor 5 is fixedly mounted on the feeding box 3; it is used to drive the rotating rod 6, which is fixedly connected to its output end, to rotate, thereby driving the rotating mechanism, the fixing mechanism, the crushing mechanism, the rotating mechanism, and the stirring mechanism to rotate.

[0058] A rotating rod 6 is mounted on the first motor 5, and one end of the rotating rod 6 is fixedly connected to the output end of the first motor 5; it is used to drive the first fixed sleeve 11, the second fixed sleeve 17 and the third fixed sleeve 19 to rotate.

[0059] Reference Figure 3 and Figure 4 In a preferred embodiment, a rotating mechanism is fixedly mounted on the rotating rod 6; the rotating mechanism includes:

[0060] The first fixed sleeve 11 is fixedly mounted on the rotating rod 6;

[0061] Two rotating plates 12 are provided, and the two rotating plates 12 are symmetrically arranged on the first fixed sleeve 11 and fixedly connected to the first fixed sleeve 11.

[0062] During operation, the rotating rod 6 transmits kinetic energy to drive the first fixed sleeve 11 to rotate, and the first fixed sleeve 11 drives the rotating plate 12 and the fixed plate 13 to rotate, thereby driving the fixed mechanism to rotate. The rotating plate 12 is used to push the coal powder agglomerate to rotate, so that the coal powder agglomerate with a radius smaller than the radius of the filter screen hole reaches the rotating mechanism through the filter plate 7.

[0063] Reference Figure 4 and Figure 5 In a preferred embodiment, two fixing mechanisms are provided, symmetrically arranged on the rotating mechanism and fixedly connected to it; the fixing mechanism includes:

[0067] Reference Figure 4 and Figure 5 In a preferred embodiment, the crushing mechanism comprises two parts, which are mounted on the fixed mechanism and rotatably connected to it; the crushing mechanism includes:

[0068] Two rotating rollers 15 are provided, and the two rotating rollers 15 are rotatably mounted on the support plate 14;

[0069] Two crushing rollers 16 are provided, and the two crushing rollers 16 are disposed on the rotating roller 15 and fixedly connected to the rotating roller 15.

[0070] During operation, the support plate 14 drives the rotating roller 15 to rotate, and the rotating roller 15 drives the crushing roller 16 to rotate on the filter plate 7. The crushing roller 16 performs preliminary crushing of the coal powder lumps on the filter plate 7.

[0071] The filter plate 7 is fixedly mounted on the feed box 3 and rotatably connected to the rotating rod 6; it is used to allow coal powder lumps with a radius smaller than the radius of the holes in the filter plate 7 to pass through, preventing the coal powder lumps from being too large and causing blockage.

The rotation of the spiral stirring blade 18 generates shearing force to further crush the coal powder lumps after initial crushing, preventing the coal powder lumps from becoming too large and causing blockage at the discharge port 8. Moreover, the spiral stirring blade 18 can continuously transport the initially crushed coal powder lumps to the discharge port 8, preventing a large amount of coal powder lumps from accumulating in one place and causing blockage.

[0079] During operation, the rotating rod 6 drives the third fixed sleeve 19 to rotate, and the third fixed sleeve 19 drives the stirring blade 20 to rotate. The stirring blade 20 is used to stir the coal powder at the discharge port 8 to prevent the coal powder from accumulating at the discharge port 8 and causing blockage.

[0080] The discharge port 8 is located on the feeding box 3.

[0081] Working principle: Coal powder is manually poured into the feed trough 9. Under the action of gravity, the coal powder flows along the inclined plate 10 through the feed inlet 4 into the discharge box 3 and falls onto the filter plate 7. The first motor 5 is started, which drives the rotating rod 6 to rotate. The first fixed sleeve 11, the second fixed sleeve 17, and the third fixed sleeve 19 of the rotating rod 6 rotate. The first fixed sleeve 11 drives the fixed plate 13 and the rotating plate 12 to rotate. The fixed plate 13 drives the support plate 14 to rotate. The support plate 14 drives the rotating roller 15 to rotate. The rotating roller 15 drives the crushing roller 16 to rotate. The crushing roller 16 crushes the large, adhered coal powder pieces. The rotating plate 12 rotates to push the crushed coal powder to move and reach the spiral mixing blade 18 through the holes of the filter plate 7. The second fixed sleeve 17 drives the spiral mixing blade 18 to rotate. The spiral mixing blade 18 continuously transports the crushed coal powder to the discharge port 8 and generates a certain shearing force to further crush the crushed coal powder pieces. The third fixed sleeve 19 drives the mixing blade 20 to rotate. The mixing blade 20 mixes the coal powder to prevent the coal powder from accumulating at the discharge port 8 and causing blockage.
