Description

Technical Field

[0001] This utility model relates to the technical field of pellet production, and in particular to a double-roller extrusion pelletizer for pellet production. Background Technology

[0002] Pelletizing refers to the process of processing powdery, granular, or other bulk materials into aggregates with a certain shape (usually spherical or near-spherical) and strength through specific processing techniques. The main raw materials are coal mines, iron mines, etc. When processing such materials, a double-roller extrusion pelletizing machine is used to process them.

[0003] A double-roller extrusion pelletizer is a device used to produce spherical materials. When the device is working, the material enters the gap between the two rollers evenly from the top of the device or the feed port. As the rollers rotate, the material is shaped into a spherical shape due to the squeezing action of the two rollers.

[0004] When using existing pelletizing machines, raw materials need to be poured into the feed inlet. The raw materials enter the equipment through the feed inlet for processing and are then conveyed out from the output outlet below. If the raw material is coal powder, when the coal powder is poured into the feed inlet, the small conveying outlet below the feed inlet causes the coal powder to accumulate at the conveying outlet, which affects the amount of coal powder conveyed and prolongs the equipment processing time. Utility Model Content

[0005] The purpose of this invention is to provide a double-roller extrusion pelletizing machine for pellet production, so as to solve the problems mentioned in the background art.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] By incorporating an anti-clogging component, pulverized coal is poured into the feed frame. The slider, via the first telescopic rod, moves the stirring rod above the feed frame. Then, the first telescopic rod drives the stirring rod to insert into the pulverized coal. The motor, via the rotating shaft, drives the rotating disk and the stirring rod to rotate, causing the stirring rod to rotate along with the pulverized coal in the feed frame. This creates gaps in the pulverized coal as it rotates, allowing it to pass through these gaps into the conveying port at the bottom inside the feed frame. This facilitates the pulverized coal entering the equipment for processing, preventing its accumulation at the conveying port below the feed frame, thus avoiding impacts on the pulverized coal conveying capacity, restoring normal equipment operation time, and solving the problems in the existing technology.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] Given that the existing pelletizing machine requires raw materials to be poured into the feed inlet, and then processed inside the equipment and conveyed out from the output outlet below, if the raw material is pulverized coal, the pulverized coal will accumulate at the conveying outlet due to the small size of the conveying outlet below the feed inlet, thus affecting the amount of pulverized coal conveyed and prolonging the equipment processing time.

The guide plate 15 is used to transport the processed pellets outward.

[0046] Anti-blocking component 20;

[0047] Anti-blocking component 20 includes:

[0048] Guide rail 22 is fixed to the top two edges of the feed frame 12;

[0049] Slider 23 is slidably connected to the surface of guide rail 22;

[0050] The first telescopic rod 24 is fixed to the top of the slider 23;

[0051] Motor 26 is located between the inner side and the upper side of the first telescopic rod 24;

[0052] The rotating shaft 27 is fixed to the output end of the motor 26;

[0053] Rotating disk 28 is fixed at the bottom end of rotating shaft 27;

[0054] The stirring rod 29 is fixed to both sides of the bottom end of the rotating disk 28, and the bottom end extends to the inside of the feed frame 12;

[0055] The guide rail 22 is used for connecting and moving the slider 23. The slider 23 is used for connecting the first telescopic rod 24. The first telescopic rod 24 is used to drive the motor 26 and the stirring rod 29 to move downward. The motor 26 is used to drive the rotating shaft 27 to rotate. The rotating shaft 27 is used to drive the rotating disk 28 and the stirring rod 29 to rotate. The rotating disk 28 is used for connecting the stirring rod 29 and the rotating shaft 27. The stirring rod 29 stirs the coal powder in the feed frame 12.

[0056] A support rod 21 is fixedly connected between one end of the guide rail 22 and one side of the body 11, and a power block 231 is fixedly connected to the other end of the guide rail 22. The power block 231 is electrically connected to the slider 23.

[0057] The support rod 21 is used to support the guide rail 22, and the power block 231 provides power to the slider 23, which moves by electricity.

[0058] The top end of the first telescopic rod 24 is fixedly connected to a connecting rod 25, and an annular plate 261 is fixedly connected between opposite ends of the connecting rod 25. The bottom end of the motor 26 is fixedly connected to the top end of the annular plate 261, the rotating shaft 27 is rotatably connected to the inside of the annular plate 261, and the rotating disk 28 is located below the annular plate 261.

[0059] A vertical rod 283 is fixedly connected to the outer side of the annular plate 261. The vertical rod 283 and the connecting rod 25 are placed alternately. A connecting plate 281 is fixedly connected between the bottom ends of the vertical rods 283. A connecting groove 282 is opened on the inner side of the connecting plate 281. The connecting groove 282 is engaged with the outer end of the rotating disk 28.

[0060] The connecting rod 25 is used to connect the first telescopic rod 24 and the annular plate 261. The connecting rod 25 and the annular plate 261 are used together to support the motor 26 and the rotating shaft 27. The vertical rod 283 is used to connect the connecting plate 281 and the annular plate 261 and to limit the connection plate 281. The connecting groove 282 is used for the rotation of the rotating disk 28, so that the connecting plate 281 limits the rotation of the rotating disk 28 through the connecting groove 282. When the motor 26 drives the rotating disk 28 to rotate through the rotating shaft 27, the rotating disk 28 rotates in the connecting groove 282.

[0061] In use, the first telescopic rod 24 and the slider 23 are located on one side of the feed frame 12, with the first telescopic rod 24 in the extended state. When the coal powder is poured into the feed frame 12, the power block 231 provides power to the slider 23 because it is electrically connected to the power block 231. The slider 23 moves by electricity, and the slider 23 moves above the feed frame 12 via the first telescopic rod 24 and the connecting rod 25, driving the motor 26 and the stirring rod 29. Then, the first telescopic rod 24 retracts, causing the first telescopic rod 24 to drive the motor 26 and the stirring rod 29. The stirring rod 29 moves downward, causing it to insert into the coal powder. Then, the motor 26 starts and drives the rotating shaft 27 to rotate through its output end. This causes the rotating shaft 27 to drive the rotating disk 28 and the stirring rod 29 to rotate together. This causes the stirring rod 29 to drive the coal powder in the feed frame 12 to rotate together, thus creating gaps in the coal powder during rotation. The coal powder enters the conveying port at the lower inner side of the feed frame 12 through these gaps, allowing it to enter the equipment for processing. This prevents the coal powder from accumulating at the conveying port at the lower inner side of the feed frame 12.

[0062] Specifically, such as Figure 1 , Figures 5-6 As shown, it also includes a cleanup component 30;

[0063] Cleanup component 30 includes:

[0064] The movable plate 31 is closely attached to the back side of the outer end of the fixed rod 13;

[0065] The second telescopic rod 32 is fixed to the top surface of the outer end of the movable plate 31;

[0066] Long rod 33 is fixed to the top of the second telescopic rod 32;

[0067] Mounting slot 34 is provided on one side of long rod 33;

[0068] The movable plate 31 is used to connect the second telescopic rod 32, the second telescopic rod 32 is used to connect the long rod 33, the long rod 33 is used to open the mounting groove 34, and the mounting groove 34 is used to insert the mounting plate 35.

[0069] A mounting plate 35 is inserted into the inner side of the mounting groove 34, and a brush 36 is fixedly connected to the bottom surface of the outer end of the mounting plate 35. Limiting rods 37 pass through both sides of the connection between the mounting plate 35 and the mounting groove 34.

[0070] Mounting plate 35 is used for the connection between brush 36 and long rod 33. Brush 36 cleans the coal powder on the outer end surface of conveyor belt 14, and limiting rod 37 limits the mounting plate 35 when it is inserted.

[0071] Mounting slot 34 and mounting plate 35 are both provided with limiting holes 38 at the through-holes of limiting rod 37. Limiting rod 37 is threadedly connected to limiting hole 38. Movable shaft 311 is movably connected to the tight-fitting part of movable plate 31 and fixed rod 13.

[0072] The limiting hole 38 is used for the insertion and rotation of the limiting rod 37. When the mounting plate 35 is inserted into the mounting groove 34, the limiting holes 38 on the surfaces of the two are aligned. At this time, the limiting rod 37 is inserted into the limiting hole 38 to limit the mounting plate 35 after insertion. When the brush 36 is in use, the second telescopic rod 32 is rotated so that the second telescopic rod 32 drives the movable plate 31 to rotate through the movable shaft 311, so that the brush 36 is in close contact with the outer end of the conveyor belt 14.

[0073] In use, hold the mounting plate 35 by hand and insert it into the mounting groove 34, aligning the limiting holes 38 on both surfaces. Then, insert the limiting rod 37 into the limiting hole 38 and rotate it to limit the mounting plate 35 after insertion. Next, rotate the second telescopic rod 32 by hand. The force of rotation is transmitted through the second telescopic rod 32 and the movable plate 31 to rotate the movable shaft 311, causing the second telescopic rod 32 and the movable plate 31 to rotate through the movable shaft 311. Then, the second telescopic rod 32 is adjusted according to the distance between the brush 36 and the conveyor belt 14, so that the brush 36 is in close contact with the outer end of the conveyor belt 14. When the conveyor belt 14 rotates, the brush 36 cleans the coal dust on the outer end surface of the conveyor belt 14. After cleaning, the second telescopic rod 32 extends upward, causing the brush 36 to separate from the conveyor belt 14, so that the cleaned coal dust falls outward, thus completing the cleaning of the conveyor belt 14 and preventing coal dust from remaining on the surface of the conveyor belt 14.

[0074] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
