Description

Technical Field

[0001] This utility model provides a screening device, belonging to the field of clay product manufacturing technology, and particularly relates to a raw material screening device for clay product manufacturing. Background Technology

[0002] Clay products are various items made primarily from clay through processing, shaping, and firing. During processing, the clay is carefully treated to remove impurities and adjust its properties. In the shaping stage, people skillfully use molds or machinery to mold the clay into various shapes, showcasing human ingenuity. Firing is the crucial step; under specific temperature and atmospheric conditions, the clay undergoes complex physical and chemical changes, becoming hard, durable, and possessing excellent properties. Clay products are diverse, with pottery, porcelain, and stoneware being typical examples. They each have unique characteristics in terms of texture, water absorption, and firing temperature, demonstrating the rich and varied properties of clay products. These products are widely used in people's lives, not only in construction (e.g., bricks and tiles), but also in industry (e.g., ceramic insulators, crucibles), and in the arts (e.g., exquisite sculptures and decorations), quietly adding color and convenience to human life. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this application provides a raw material screening device for clay product production, which solves the problems of incomplete screening and low efficiency, and improves screening accuracy.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a raw material screening device for clay product production, including a first screen, and a second screen penetrating through itself is provided inside the first screen;

[0005] The first screen includes an outer frame fitted over itself, and a first rotating shaft passing through itself is provided inside the outer frame. One end of the first rotating shaft is fixedly connected to a first gear.

[0006] The second screen includes an inner frame fitted over itself. Inside the inner frame is a second rotating shaft that passes through itself, the first rotating shaft, and the first gear. On the side of the first gear away from the first rotating shaft, there is a second gear that is fixedly connected to the second rotating shaft.

[0007] Preferably, the inner frame has a limiting ring with a diameter larger than itself in the middle, and both ends of the inner frame are sealing plates.

[0008] Preferably, the bottom of the outer frame is provided with a mounting groove that corresponds to and fits into the limiting ring, and both ends of the outer frame are provided with several through holes that penetrate through itself.

[0009] Preferably, the end of the first rotating shaft away from the first gear is fixedly connected to a locking nut structure placed outside the sealing plate.

[0010] Preferably, the mesh size of the first screen is smaller than that of the second screen; a limiting post is fixedly connected inside the outer frame and placed inside the first screen.

[0011] Preferably, the first screen is fitted with a first storage shell corresponding to itself, a second storage shell corresponding to the outer frame is fixedly connected to one side of the first storage shell, and a third storage shell corresponding to the second screen is fixedly connected to the other side of the second storage shell.

[0012] Preferably, the first gear has a pair of transmission gears that mesh with itself on one side, and a drive gear that meshes with itself and the second gear on the side of the transmission gear away from the first gear. The drive gear is connected to the drive motor.

[0013] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0014] In the raw material screening device for clay product production of this utility model, a drive motor drives a drive gear to rotate, which meshes with a first gear, causing the first screen to rotate around a first rotating shaft. Since the first gear and the second gear are fixedly connected to a second rotating shaft, and the second rotating shaft passes through the first rotating shaft and the first gear, the second gear rotates simultaneously with the first screen, thus driving the second screen to rotate around the second rotating shaft. In this way, the first and second screens rotate simultaneously on their respective shafts, achieving multi-stage screening of the clay raw material. The clay raw material on the first screen is subjected to centrifugal force and gravity generated by rotation, continuously moving and being screened through the sieve holes. Materials larger than the first screen hole diameter remain on the first screen, while smaller materials pass through and fall onto the second screen. On the second screen, the material is also subjected to centrifugal force and gravity generated by rotation, continuing to be screened. Materials larger than the second screen hole diameter remain on the second screen, while materials smaller than the hole diameter are collected, thereby achieving multi-stage screening of materials of different particle sizes.

[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0029] 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.

[0030] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] like Figure 1 and Figure 2 As shown, a raw material screening device for clay product production includes a first screen 1, with a second screen 2 penetrating through its interior. The first screen 1 includes an outer frame 11 fitted over itself, with a first rotating shaft 12 penetrating through its interior. One end of the first rotating shaft 12 is fixedly connected to a first gear 13. The second screen 2 includes an inner frame 21 fitted over itself, with a second rotating shaft 22 penetrating through itself, the first rotating shaft 12, and the first gear 13. A second gear 23 is fixedly connected to the second rotating shaft 22 on the side of the first gear 13 away from the first rotating shaft 12. A limiting ring 24 with a diameter larger than itself is provided in the middle of the inner frame 21, and both ends of the inner frame 21 are sealing plates 25. A locking nut structure 16 placed outside the sealing plate 25 is fixedly connected to the end of the first rotating shaft 12 away from the first gear 13.

[0033] In this embodiment, the independent rotation capability of the first rotating shaft 12 and the second rotating shaft 22 is crucial for achieving multi-stage screening. In actual operation, the first screen 1 and the second screen 2 achieve coaxial but opposite-directional rotation via the first gear and the second gear. To further improve the screening effect, the limiting ring 24 also plays an important role. It not only prevents the second screen 2 from shifting during rotation but also adjusts the distance between the second screen 2 and the first screen 1, thereby adapting to the screening requirements of different particle sizes. In addition, the locking nut structure 16 also has an important application in the installation and maintenance of the equipment. It ensures the stability of the first rotating shaft 12, preventing loosening during rotation, thus ensuring the continuity and reliability of the screening process.

[0034] like Figure 3 and Figure 4 As shown, the mesh size of the first screen 1 is smaller than that of the second screen 2; a limiting post 17 is fixedly connected inside the outer frame 11 and placed inside the first screen 1. A pair of transmission gears 26 that mesh with itself are provided on one side of the first gear 13, and a drive gear 27 that meshes with itself and the second gear 23 is provided on the side of the transmission gear 26 away from the first gear 13. The drive gear 27 is connected to the drive motor.

[0035] In this embodiment, the limiting post 17 plays a crucial role in the screening process. It is fixedly connected inside the outer frame 11 and located inside the first screen 1, effectively limiting the position of the first screen 1 and preventing displacement or shaking during rotation. This not only ensures the stability of the screening process but also avoids inaccurate screening caused by screen displacement. Simultaneously, the design of the limiting post 17 also helps maintain the shape of the first screen 1, ensuring that the screen maintains good screening performance even after prolonged use.

[0036] In the gear transmission system, the meshing of the first gear 13 with the transmission gear 26, and the meshing of the transmission gear 26 with the drive gear 27 and the second gear 23, constitute a complex transmission system. This design allows power to be effectively transmitted from the drive motor to the first screen 1 and the second screen 2, achieving synchronous but opposite rotation of the two screens. By adjusting the gear ratio, the rotational speed of the two screens can be precisely controlled, thereby optimizing the screening process. For example, when screening finer materials, the rotational speed can be appropriately reduced to improve screening accuracy; while when processing larger particle sizes, the rotational speed can be increased to accelerate screening and improve production efficiency.

[0037] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
