Description

Technical Field

[0001] This utility model relates to the field of pelletizing equipment technology, specifically a semi-dry material pelletizing machine. Background Technology

[0002] A pelletizing machine is a mechanical device used to produce spherical particles, widely used in the metallurgical, mining, chemical, building materials, and feed industries. It primarily functions by mixing semi-dry powdery materials and shaping them into spherical particles with a certain strength, facilitating transportation, storage, and subsequent processing and use. The working principle of a pelletizing machine involves using mechanical force and friction to mix, knead, and compress the materials; therefore, the rotary drum is the core component of the pelletizing machine.

[0003] Currently, the pelletizing process involves placing semi-dry material into a pelletizing machine, where it is rotated to form spherical shapes. During the pelletizing process, uneven force distribution results in significant differences in the size of the pellets. The conventional solution is to screen out the larger pellets and continue pelletizing the smaller ones. However, this conventional production method still has the following shortcomings:

[0004] The pelletizing rate of a single batch of semi-dry material is low, so it is necessary to gradually increase the amount of semi-dry material. Utility Model Content

[0005] In order to solve the technical problems existing in the background art, this utility model provides a semi-dry material pelletizing machine, which has a high pelletizing rate of single batch of semi-dry material and does not require multiple additions of semi-dry material during the process.

[0006] The technical solution adopted by this utility model is:

[0008] Furthermore, a drive motor is installed inside the housing, and the shaft of the drive motor is tilted upward.

[0009] Furthermore, an opening is provided on the opposite side of the flat bottom end of the rotary cylinder;

[0010] The flat bottom end of the rotating cylinder is coaxially connected to the rotating shaft of the drive motor.

[0011] Furthermore, the housing is symmetrically provided with support roller groups, which are tumblingly connected to the outer wall of the rotating cylinder.

[0012] Furthermore, a mounting arm is fixedly provided on the housing, and a mounting shaft extends from the end of the mounting arm, which is used to install the material dispensing mechanism.

[0013] Furthermore, the material dispensing mechanism includes:

[0014] An inclined fixed shaft has a material distribution main board extending from one side of its lower part, an extension plate extending from the fixed shaft on the opposite side of the material distribution main board, and a top cap coaxially disposed at the upper end of the fixed shaft.

[0018] Furthermore, the lower fixing hoop, fixing rod, and upper fixing hoop are configured as a symmetrical structure and are fixedly connected by bolts and nuts.

[0019] The beneficial effects of this utility model of a semi-dry material pelletizing machine are as follows:

[0020] The material separation mechanism separates spherical materials of different sizes, rounds the smaller spherical materials, and reduces the contact between the larger spherical materials and the semi-dry materials to prevent them from becoming rounded further. Attached Figure Description

[0030] To more clearly and explicitly illustrate the specific implementation objectives and methods of this utility model, the technical solution of this utility model will be fully described below. The described embodiments are only some embodiments of this utility model, not all embodiments. Without creative effort, all other embodiments based on the described embodiments of this utility model are within the protection scope of this utility model.

[0031] This utility model relates to a semi-dry material pelletizing machine, such as... Figure 1 As shown, it includes:

[0032] The housing 10 is set on a horizontal ground. A drive motor is installed inside the housing 10. The shaft of the drive motor is tilted upward. Support roller groups 11 are symmetrically arranged on the housing 10. The support roller groups 11 are rolledly connected to the outer wall of the rotating cylinder 2.

[0033] A flat-bottomed spherical rotating cylinder 2 is rotatably mounted on the housing 10. An opening is provided on the opposite side of the flat bottom end of the rotating cylinder 2. The flat bottom end of the rotating cylinder 2 is coaxially connected to the rotating shaft of the drive motor.

[0034] A mounting arm 12 is fixedly mounted on the housing 10. A mounting shaft extends from the end of the mounting arm 12, and the mounting shaft is used to mount the material distribution mechanism 3. The end of the material distribution mechanism 3 extends into the rotating drum 2. The material distribution mechanism 3 separates the spherical materials rotating inside the rotating drum 2 according to their size, keeping the smaller spherical materials at the bottom of the rotating drum 2 and continuing to roll them into round shapes. The material distribution mechanism 3, as shown... Figure 2 , Figure 3 , Figure 4 As shown, it includes:

[0035] An inclined fixed shaft 30 has a material distribution main board 31 extending from one side of its lower part. The material distribution main board 31 is located on the receiving side and is curved with the convex surface facing upward. An extension plate 32 extends from the fixed shaft 30 on the opposite side of the material distribution main board 31. A top cap 33 is coaxially provided at the upper end of the fixed shaft 30.

[0036] The fixed shaft 30 is fitted with a lower fixing hoop 41, and the mounting shaft is fitted with an upper fixing hoop 43. A fixing rod 42 is provided between the lower fixing hoop 41 and the upper fixing hoop 43. The lower fixing hoop 41, the fixing rod 42, and the upper fixing hoop 43 are arranged in a symmetrical structure and are fixedly connected by bolts and nuts.

[0037] By changing the position of the upper fixing hoop 43 on the mounting shaft and the position of the lower fixing hoop 41 on the fixing shaft 30, the gap between the material distribution main plate 31 and the inner wall and lower inner bottom of the rotating drum 2 can be adjusted. When the drive motor drives the rotating drum 2 to rotate, the relatively larger spherical materials have greater inertia and will pass through the gap between the material distribution main plate 31 and the rotating drum 2, and will continue to be thrown upwards; conversely, the relatively smaller spherical materials have less inertia and will be blocked by the material distribution main plate 31 and return to the lower part of the rotating drum 2 to continue rolling.

[0038] In summary, the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Based on the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification. All equivalent variations and modifications of the shape, structure, features, and spirit described in the claims of this utility model should be included within the scope of the claims of this utility model.
