Description

Technical Field

[0001] This utility model belongs to the field of pelletizing technology, and in particular relates to a pelletizing disc material crushing device and a pelletizing machine. Background Technology

[0002] During the pelletizing process of a pelletizing machine, a small number of irregular lumps inevitably form due to a combination of factors, including insufficient uniformity of raw material mixing, lag in the moisture control system, wear of the inner wall tiles of the pelletizing disc, and aging of the scraper assembly. These initially small lumps gradually accumulate and enlarge as the pelletizing disc continues to operate, absorbing surrounding materials. This results in a significant uneven particle size distribution in the green pellets (target particle size of 12mm-16mm) within the pelletizing disc, and a substantial decrease in the overall compressive strength of the green pellets.

[0003] The manual crushing equipment commonly used in the industry not only requires operators to frequently intervene in the production process, resulting in low crushing efficiency, but also easily causes mechanical damage to the surrounding green pellets during the crushing process, affecting the overall quality stability of the finished pellets.

A crushing component is provided on the sorting fork 3. The crushing assembly includes a star-shaped stirring wheel 41, which is mounted on a rotating shaft 42. Both ends of the rotating shaft 42 are rotatably mounted on the sorting fork 3, so that the star-shaped stirring wheel 41 rotates with the rolling of green pellets to crush unqualified material blocks in the pelletizing pan.

[0024] In a preferred embodiment of this utility model, the telescopic assembly includes a telescopic rod 21, the driving end of the telescopic rod 21 is mounted on the support frame 1, the telescopic end of the telescopic rod 21 is hinged to one end of a connecting rod 22, and the other end of the connecting rod 22 is connected to a sorting fork 3; the sorting fork 3 is connected to the support frame 1 through a connecting rod 23, and the connecting rod 23 is hinged to the support frame 1.

[0025] Specifically, the second connecting rod 23 is a 4*4cm square tube. Through the telescopic movement of the telescopic rod 21, the sorting fork 3 can flexibly extend and retract within the pelletizing tray, improving the adaptability and ease of operation of the device. The hinged connection between the first connecting rod 22 and the second connecting rod 23 facilitates adjustment of the angle of the sorting fork 3, further enhancing its stability and flexibility.

[0026] In a preferred embodiment of this utility model, the telescopic end of the telescopic rod 21 is connected to the connecting rod 22 by bolts, and the outer wall of the bolt at the contact point between the bolt and the telescopic rod 21 and the connecting rod 22 is unthreaded.

[0027] Specifically, the detachable nature of the bolted connection makes maintenance or component replacement more convenient, improving maintenance efficiency. One end of the screw passes through the telescopic rod 21 and connecting rod 22 and is threadedly connected to the nut. The outer wall of the screw at the contact point with the telescopic rod 21 and connecting rod 22 is smooth and threadless, allowing the connecting rod 22 to rotate relative to the telescopic rod 21, facilitating adjustment of the angle of the sorting fork 3.

[0028] In a preferred embodiment of this utility model, the connecting rod 23 is connected to the support frame 1 by bolts, and the outer wall of the bolt at the contact point between the connecting rod 23 and the support frame 1 is unthreaded.

[0029] Specifically, one end of the screw passes through the connecting rod 23 and the support frame 1 and is threadedly connected to the nut. The outer wall of the screw at the contact point with the connecting rod 23 and the support frame 1 is smooth and without threads, so that the connecting rod 23 can rotate relative to the support frame 1, which facilitates the adjustment of the angle of the sorting fork 3.

[0030] In a preferred embodiment of this invention, the star-shaped stirring wheel 41 is located above the gap of the sorting fork 3, ensuring that green pellets of the correct size can pass through smoothly, avoiding damage to normal green pellets and protecting their quality. Simultaneously, it can directly contact the intercepted material blocks, ensuring the high efficiency of the crushing process.

[0031] In a preferred embodiment of the present invention, the two ends of the rotating shaft 42 are respectively connected to the sorting fork 3 through two bearing seats 43, and the two bearing seats 43 are respectively installed on the two sides of the sorting fork 3 away from the telescopic component.

[0032] Specifically, supported by the two bearing seats 43, the rotating shaft 42 can rotate smoothly, reducing vibration and wear caused by unbalanced forces and improving the stability of the device's operation.

[0033] In a preferred embodiment of this utility model, the sorting fork 3 is arranged parallel to the pelletizing disc 5 during operation.

[0034] Specifically, the sorting fork 3 is set parallel to the pelletizing disc 5 during use, ensuring that the sorting fork 3 can effectively screen and process the material blocks in the pelletizing disc 5. The 45-degree inclination angle ensures that the green pellets are evenly stressed during rolling, reducing the problems of uneven green pellet size and strength reduction caused by uneven rolling, thereby improving the overall quality of the green pellets.

[0035] In a preferred embodiment of this utility model, the diameter of the fork teeth of the sorting fork 3 is 18mm, and the distance between adjacent fork teeth is 3cm to 4cm.

[0036] Specifically, the sorting fork 3 is made of steel bars with a diameter of 18mm. The spacing between adjacent fork teeth is 3cm to 4cm. This size design can effectively screen out qualified green balls, ensuring that green balls of 12mm to 16mm can pass through smoothly, while larger pieces of material are intercepted above the sorting fork 3, improving screening efficiency. The number of fork teeth and star-shaped agitator 41 is selected according to the actual situation.

[0037] In a preferred embodiment of this utility model, the support frame 1 is made of channel steel.

[0038] Specifically, the shape and structure of the channel steel enable it to provide stable support within the support frame 1, reducing vibration and swaying and improving the operational reliability of the device. The material properties of the channel steel give it excellent corrosion resistance and wear resistance, extending the service life of the support frame 1 and reducing maintenance costs.

[0039] A pelletizing machine includes a pelletizing machine body, the pelletizing machine body is provided with a pelletizing disc 5 and an operating platform 6, and a pelletizing disc material crushing device is installed on the operating platform 6.

[0040] The diameter of the ball-forming disk is 6 meters, and the tilt angle of the ball-forming disk 5 is 44 to 46 degrees, preferably 45 degrees.

[0041] Specifically, the 45-degree tilt angle ensures that the green pellets are evenly stressed during rolling, reducing the problems of uneven pellet size and strength reduction caused by uneven rolling, thereby improving the overall quality of the green pellets.

[0042] Working principle of a pelletizing disc crushing device and pelletizing machine: When material lumps are generated in the pelletizing pan 5, the sorting fork 3 is extended into the surface of the green pellets in the pelletizing pan 5 through the telescopic end of the telescopic component, and the sorting fork 3 is parallel to the pelletizing pan 5. The rotational force of the green pellets in the pan drives the star-shaped stirring wheel 41 to rotate. The rotation of the star-shaped stirring wheel 41 can effectively crush the unqualified material lumps in the pelletizing pan, and the green pellets of qualified size can naturally pass through the gap of the sorting fork 3, thereby ensuring that the green pellets in the pelletizing pan have uniform particle size.

[0043] When there are no material blocks in the ball tray, the sorting fork 3 is lifted by the telescopic end of the telescopic component to avoid the sorting fork 3 colliding with qualified green balls for a long time, which would affect the quality of the green balls.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
