[0004] In the aforementioned device, sludge raw materials are extruded through a granulating plate to form sludge granules. These sludge granules are then cured at high temperatures to produce ceramsite. High-quality ceramsite is spherical or elliptical in shape. These ceramsite particles are uniform, have good flowability, and are easily distributed evenly in materials such as concrete. However, sludge raw materials processed through the granulating plate produce cylindrical sludge granules, resulting in a lower product quality. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an apparatus for preparing ceramsite from sludge pyrolysis biochar, comprising an equipment shell, an organic cylinder fixedly installed inside the equipment shell, an extrusion screw rotatably installed inside the cylinder, a feed hopper fixedly installed on the cylinder, a discharge mechanism connected to the bottom of the cylinder, the discharge mechanism including a discharge port fixedly installed at the bottom of the cylinder, a granulation plate fixedly installed at the lower end of the discharge port, an adjusting cylinder connected to the discharge port, the adjusting cylinder having spiral patterns inside, a threaded hole opened at the upper edge of the adjusting cylinder, and a kneading mechanism provided below the adjusting cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this application, sludge particles fall into the gap between the upper and lower discs. Subsequently, driven by the transmission shaft, the movable shaft rotates. The rotation of the movable shaft in turn causes the swing arm to swing. During the swinging of the swing arm, the lower disc swings below the upper disc, kneading the sludge particles to form spherical particles, thereby effectively improving the quality of the product.

By adjusting the speed of the drive motor, the quality of the sludge particles can be precisely controlled. Furthermore, the user can control the up-and-down movement of the adjusting cylinder by loosening the bolts in the threaded hole. The up-and-down movement of the adjusting cylinder will cause a corresponding displacement of the upper disc, thereby adjusting the gap between the upper and lower discs, ultimately achieving fine control over the size of the prepared ceramsite.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for an apparatus for preparing ceramsite from sludge pyrolysis biochar, including an equipment shell 1, an organic cylinder 2 fixedly installed inside the equipment shell 1, an extrusion screw 3 rotatably installed inside the cylinder 2, a feed hopper 4 fixedly installed on the cylinder 2, a discharge mechanism 7 connected to the bottom of the cylinder 2, and a kneading mechanism 6 provided below the adjusting cylinder 704. The kneading mechanism 6 can knead sludge particles into spherical shapes, improving product quality. Furthermore, the discharge mechanism 7, in conjunction with the kneading mechanism 6, can adjust the size of the ceramsite prepared from the sludge.

[0024] like Figure 2 and Figure 3As shown, the kneading mechanism 6 includes a support column 603 fixedly installed inside the equipment housing 1 and an upper plate 601 fixedly installed at the lower end of the adjusting cylinder 704. A movable shaft 607 is rotatably installed on the support column 603, and a swing arm 606 is rotatably installed on the movable shaft 607. The lower plate 602 is rotatably connected to the end of the swing arm 606. A reducer 608 is connected to the movable shaft 607. A transmission shaft 5 is provided between the reducer 608 and the extrusion screw 3. A receiving plate 605 is fixedly installed on the support column 603 and is tilted to one side. A discharge port 604 is fixedly installed on one side of the receiving plate 605. A bearing is provided on the support column 603, and the movable shaft 607 is rotatably installed on the support column 603 through the bearing.

[0025] Specifically, during the sludge treatment process, sludge particles fall into the gap between the upper disc 601 and the lower disc 602. Subsequently, driven by the transmission shaft 5, the movable shaft 607 begins to rotate. During this rotation, the movable shaft 607 further drives the swing arm 606 to swing. The swing arm 606, in turn, causes the lower disc 602 to swing below the upper disc 601. This series of mechanical actions kneads the sludge particles into a ball shape under the action of the swing arm 606, effectively improving the quality of the final product.

[0026] like Figure 3 , Figure 4 and Figure 5 As shown, the discharge mechanism 7 includes a discharge port 701 fixedly installed at the bottom of the barrel 2. A pelletizing plate 702 is fixedly installed at the lower end of the discharge port 701. An adjusting cylinder 704 is connected to the discharge port 701. The adjusting cylinder 704 has a spiral pattern 703 inside. A threaded hole 705 is opened at the upper edge of the adjusting cylinder 704. A protective cover 708 is fixedly installed at the middle position of the upper surface of the pelletizing plate 702. A drive motor 707 is fixedly installed inside the protective cover 708. A scraper 706 is fixedly installed at the output end of the drive motor 707. A spiral protrusion is opened on the outer wall of the discharge port 701. The adjusting cylinder 704 is connected to the discharge port 701 through the spiral protrusion.

[0027] Specifically, during the sludge treatment process, when the raw material is discharged through the granulating plate 702, the scraper 706 can be rotated by the operation of the drive motor 707. This rotation cuts the sludge raw material discharged through the granulating plate 702 into uniform particles. Users can also precisely control the rotation speed of the scraper 706 by adjusting the speed of the drive motor 707, thereby adjusting the quality of the falling sludge particles. Furthermore, users can easily loosen the bolts in the threaded holes 705. Once these bolts are loosened, the adjusting cylinder 704 can be rotated to move it up and down. The up-and-down movement of the adjusting cylinder 704 will cause the upper disc 601 to move up and down accordingly, thereby adjusting the gap between the upper disc 601 and the lower disc 602. By precisely controlling the size of this gap, users can further adjust the size of the ceramsite produced from the sludge to meet different application requirements.

[0028] Working principle: When in use, the sludge raw material is poured into the feed hopper 4. Then, the motor drives the extrusion screw 3 to rotate. During the rotation of the extrusion screw 3, the sludge raw material is squeezed and discharged through the granulating plate 702. When the sludge raw material is discharged through the granulating plate 702, the drive motor 707 drives the scraper 706 to rotate, cutting the sludge raw material discharged through the granulating plate 702 into granules. The sludge granules will fall into the gap between the upper plate 601 and the lower plate 602. Then, the drive shaft 5 drives the movable shaft 607 to rotate. After the movable shaft 607 rotates, it drives the swing arm 606 to swing. During the swing of the swing arm 606, the lower plate 602 swings below the upper and lower plates 601, thereby kneading the sludge granules into a ball shape and improving product quality. Meanwhile, the user can adjust the speed of the scraper 706 by driving the motor 707, thereby adjusting the quality of the falling sludge particles. The user can also loosen the bolt in the threaded hole 705. After loosening the bolt in the threaded hole 705, the user can rotate the adjusting cylinder 704 to move up and down. After the adjusting cylinder 704 moves up and down, it will drive the upper plate 601 to move up and down, thereby adjusting the gap between the upper plate 601 and the lower plate 602, and thus adjusting the size of the ceramsite prepared from the sludge.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
