Description

Technical Field

[0001] This utility model relates to the field of screen technology, and in particular to a cleaning screen that can be adjusted in multiple stages. Background Technology

[0002] In many industrial sectors such as mining, chemicals, and food processing, material grading and screening are crucial steps in the production process. As a core component for material screening, the performance of cleaning screens directly impacts production efficiency and product quality. Currently, most cleaning screens widely used in the market are either single-screen structures or simple multi-stage screen combinations.

[0003] Cleaning screens with a single screen structure have only one size of screen opening, making it impossible to perform fine grading and screening of materials, and thus failing to meet the needs of refined material processing in industrial production. On the other hand, some cleaning screens that use multi-stage screen combinations have fixed screen opening diameters for each screen and a single vibration mode, making it impossible to flexibly adjust the vibration according to the characteristics of different materials. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a cleaning screen that can be adjusted in multiple stages.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A multi-stage adjustable cleaning screen includes a first mounting plate and a second mounting plate, which are arranged in parallel. A first screen and a second screen are fixedly installed between the first mounting plate and the second mounting plate, with the first screen located above the second screen.

[0007] Preferably, a first vibration motor is mounted on the outside of the first mounting plate, and a second vibration motor is mounted on the outside of the second mounting plate.

[0008] Preferably, the first screen is provided with a first screen hole, the second screen is provided with a second screen hole, and the diameter of the first screen hole is larger than the diameter of the second screen hole.

[0012] Preferably, both the first screen and the second screen are fixedly connected between the first mounting plate and the second mounting plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The system features a two-stage screening structure with a first screen and a second screen, where the aperture of the first screen is larger than that of the second screen, enabling graded screening of materials. Simultaneously, two vibrating motors allow independent adjustment of vibration frequency and amplitude to adapt to different materials and screening requirements, accelerating screening speed, improving screening efficiency, and achieving highly efficient and precise screening.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Reference Figure 1-3 A multi-stage adjustable cleaning screen consists of a first mounting plate 1 and a second mounting plate 2. Both mounting plates are made of high-strength alloy material and are precision-machined to ensure their parallel arrangement, providing a stable foundation for the screen's operation. The spacing between the two mounting plates is scientifically calculated and optimized to ensure both sufficient installation space and meet the requirements for material flow and screening on the screen.

[0024] A first screen 5 and a second screen 7 are fixedly installed between the first mounting plate 1 and the second mounting plate 2. The first screen 5 is located above the second screen 7, forming a two-stage screening structure. Both the first screen 5 and the second screen 7 are made of high-quality stainless steel woven mesh. This material has good wear resistance, corrosion resistance, and high strength, and can adapt to various complex material screening environments, extending the service life of the screens.

[0025] To achieve the vibration function of the screen, a first vibration motor 3 is mounted externally on the first mounting plate 1, and a second vibration motor 4 is mounted externally on the second mounting plate 2. Both the first vibration motor 3 and the second vibration motor 4 are fixed to the external of their respective mounting plates using high-strength bolts. This fixing method is stable and reliable, and can effectively transmit vibration energy. The two vibration motors can independently adjust their vibration frequency and amplitude, achieving different vibration modes through a control system to meet different materials and screening requirements. For example, for materials with larger particles and better flowability, the vibration frequency can be appropriately increased to accelerate the screening speed; for materials with smaller particles and a tendency to stick together, the vibration frequency can be decreased and the vibration amplitude increased to improve the screening effect.

[0026] The first screen 5 has a first screen hole 6, and the second screen 7 has a second screen hole 8, with the diameter of the first screen hole 6 being larger than that of the second screen hole 8. This difference in hole size design ensures that after the material passes through the first screen 5, larger particles are retained, while smaller particles continue to fall through the first screen hole 6 to the second screen 7 for further screening. The shapes of the first screen hole 6 and the second screen hole 8 are specially designed, using regular shapes such as squares or circles, to ensure consistency in screen hole size and screening accuracy. Simultaneously, the edges of the screen holes are rounded to effectively prevent material from getting stuck or clogging during the screening process.

[0027] A guide plate 9 is also installed between the first mounting plate 1 and the second mounting plate 2, located below the second screen 7. The guide plate 9 is made of smooth stainless steel plate, and its tilt angle has been precisely calculated and optimized to guide the material after screening by the second screen 7 to smoothly discharge from the screen. The guide plate 9 is fixedly connected to the mounting plate by welding, and the connection is sealed to prevent material leakage.

[0028] In addition, to facilitate the installation, disassembly, and maintenance of the screens, the first mounting plate 1 and the second mounting plate 2 are provided with mounting holes and positioning pins, which connect the screen assembly to the main structure of the cleaning screen using bolts and nuts. Meanwhile, the first screen 5 and the second screen 7 are detachably connected to the mounting plates using snap-fit ​​or bolt connections, facilitating replacement when the screens are worn or damaged.

[0029] This multi-level adjustable cleaning screen, through its reasonable structural design and functional configuration, can achieve efficient and accurate grading and screening of materials, and is widely used in material handling processes in industries such as mining, chemical, and food.

[0030] 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.
