It is mainly used to improve the combustion efficiency of coal powder, save fuel, reduce the waste of coal powder, and stabilize the calorific value of coal.

[0003] After the raw coal enters the coal pulverizing coal injection machine, it needs to be crushed to crush the raw coal into particles with larger particle size. However, when the coal is crushed by the impact of the breaker, some coal particles may splash, which will waste coal resources. Therefore, an efficient coal pulverizing coal injection machine is proposed. Summary of the invention

[0053] The second connecting pipe is arranged on the side of the main body, one end of the second connecting pipe is communicated with the side of the cylinder body away from the hydraulic press, and the other end of the second connecting pipe runs through the main body and is communicated with the outside.

[0054] When the splash guard swings downward, the splash guard pulls the pull rope, and the pull rope drives the piston to move toward the side of the breaker hammer. The piston squeezes the second spring, driving the coal dust generated when the coal is crushed to enter the cylinder body through the hollow pipe and the first connecting pipe in sequence.

[0055] When the splash plate swings upward, the second spring returns to its original position, driving the piston away from the breaker hammer. The piston drives the pull rope to return to its original position, pushing the dust in the cylinder body through the second connecting pipe and then discharged, thereby preventing the dust from accumulating on the upper part of the crushing box.

[0113] The first connecting pipe 25 is disposed inside the main body 1 , one end of the first connecting pipe 25 is connected to the side of the cylinder 19 away from the hydraulic press 5 , and the other end of the first connecting pipe 25 passes through the splash plate 18 and is connected to the hollow pipe 24 .

[0114] The second connecting pipe 26 is disposed on the side of the main body 1 , one end of the second connecting pipe 26 is connected to the side of the cylinder 19 away from the hydraulic press 5 , and the other end of the second connecting pipe 26 passes through the main body 1 and is connected to the outside.

[0115] When the splash plate 18 swings downward, the splash plate 18 pulls the pull rope 23, and the pull rope 23 drives the piston 20 to move toward the side of the breaker 6. The piston 20 squeezes the second spring 22, driving the coal dust generated when the coal is crushed to pass through the hollow tube 24 and the first connecting tube 25 in sequence into the cylinder body 19.

[0116] When the splash plate 18 swings upward, the second spring 22 is reset, driving the piston 20 away from the breaker 6, and the piston 20 drives the pull rope 23 to reset, pushing the dust in the cylinder 19 through the second connecting pipe 26 and then discharged, preventing the dust from accumulating on the upper part of the crushing box 4.

[0117] Both the first connecting pipe 25 and the second connecting pipe 26 have check valves therein.

[0118] Prevent dust backflow.

[0119] The first connecting pipe 25 and the second connecting pipe 26 are both made of hoses.

[0120] The first connecting pipe 25 and the second connecting pipe 26 are prevented from being damaged when moving.

[0121] Working principle: When using this equipment, the staff pours the coal into the feed channel 7, and the coal falls into the crushing box 4 along the feed channel 7. Then the staff starts the hydraulic press 5, and the telescopic end of the hydraulic press 5 drives the breaker 6 to rise and fall, and the breaker 6 crushes the coal. After the coal is crushed, the staff turns off the hydraulic press 5 and opens the valve 29. The coal particles fall from the valve 29 and enter the grinding box 3 to be ground into coal powder. Then the coal powder falls into the spraying bin 2 and is sprayed out from the spraying bin 2.

[0122] When the breaker 6 is crushing coal, the staff starts the reversing motor 17 through the controller 30. The reversing motor 17 works, and the rotating shaft of the reversing motor 17 drives the splash guard 18 to swing, thereby expanding the blocking range of the splash guard 18. When the splash guard 18 swings, it stirs the air to speed up the air circulation on the upper part of the crushing box 4.

[0123] When the splash plate 18 swings downward, the splash plate 18 pulls the pull rope 23, and the pull rope 23 drives the piston 20 to move toward the side of the breaker 6. The piston 20 squeezes the second spring 22, driving the coal dust generated when the coal is crushed to pass through the hollow pipe 24, the first connecting pipe 25, and the one-way valve in sequence into the cylinder body 19.

[0124] When the splash plate 18 swings upward, the second spring 22 is reset, driving the piston 20 away from the breaker 6. The piston 20 drives the pull rope 23 to reset, pushing the dust in the cylinder 19 through the one-way valve and the second connecting pipe 26 in sequence, and then discharged, preventing the dust from accumulating on the upper part of the crushing box 4.

[0125] When the breaker 6 descends, the staff controls the driving cylinder 9 to retract through the controller 30, and the telescopic ends of the two driving cylinders 9 drive the two gathering plates 10 to move in the opposite direction, and the two gathering plates 10 drive the two first wedge blocks 11 to move in the opposite direction, and the two gathering plates 10 move away from each other to prevent the gathering plates 10 from affecting the breaker 6 to crush the coal.

[0126] When the two gathering plates 10 drive the two first wedge blocks 11 to move in opposite directions, the first wedge block 11 drives the second wedge block 15 to rise, the second wedge block 15 stretches the first spring 13, drives the mounting plate 14 to rise, the mounting plate 14 drives the mounting block 16 to rise, the mounting block 16 drives the reversing motor 17 to rise, and the rotating shaft of the reversing motor 17 drives the splash plate 18 to rise, so that the splash plate 18 in a swinging state can fan the air at different heights while blocking coal particles, thereby accelerating air circulation.

[0127] When the breaker 6 rises, the staff controls the driving cylinder 9 to stretch through the controller 30, and the telescopic ends of the two driving cylinders 9 drive the two gathering plates 10 to move toward each other, and the two gathering plates 10 drive the two first wedge blocks 11 to move toward each other. The two gathering plates 10 gather the coal to the middle of the crushing box 4, which is convenient for the next crushing work of the breaker 6 and makes the coal crushed evenly.

[0128] When the two gathering plates 10 drive the two first wedge blocks 11 to move toward each other, the first wedge block 11 moves away from the second wedge block 15, and the first spring 13 contracts and resets, and the first spring 13 drives the mounting plate 14 to descend, and the mounting plate 14 drives the mounting block 16 to descend, and the mounting block 16 drives the reversing motor 17 to descend, and the rotating shaft of the reversing motor 17 drives the splash plate 18 to descend, so that the splash plate 18 in a swinging state can fan the air at different heights while blocking coal particles, thereby accelerating air circulation.

[0129] The above embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall all fall within the scope of protection of the present invention.
