The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model embodiment provides a screening device for separating mica and scheelite, such as... Figure 1-4 As shown, the screening device for separating mica and scheelite includes: a base 1; an isolation box 3 mounted on top of the base 1 via a support frame 2, the isolation box 3 being used to isolate the screening environment; a feeding hopper 4 fixed on the isolation box 3 for auxiliary feeding; a screening cylinder 5 rotatably mounted on the feeding hopper 4 and located inside the isolation box 3 for screening mica and scheelite; a discharge cylinder 9 installed at the bottom of the isolation box 3 for discharging scheelite powder; a magnetic separation structure fixed at the bottom of the discharge cylinder 9 for secondary separation of mica; and a drive assembly mounted on the isolation box 3 for flipping the screening cylinder 5.

[0021] In this embodiment, the base 1 serves as the supporting foundation for the entire screening device, ensuring stable operation. The isolation box 3 is installed on top of the base 1 via the support frame 2, achieving a stable setup. The isolation box 3 isolates the screening environment, preventing external interference and protecting the operator from dust and other hazards. The feeding hopper 4 assists in feeding, facilitating the even addition of the mica and scheelite mixture to be screened into the screening cylinder 5. The screening cylinder 5 is a key component for screening mica and scheelite; by rotating, it utilizes the difference in the passability of materials of different particle sizes on the screen to achieve preliminary separation. The discharge cylinder 9 discharges the material obtained after screening. The scheelite powder, due to its high hardness and high melting point, can be directly collected through the discharge cylinder 9 after screening. The magnetic separation structure is used for secondary separation of mica. Since common mica contains magnetic components, the magnetic separation structure can further separate the residual mica from the scheelite powder (the reason why mica can be magnetically separated is that its associated minerals are magnetic. Mica itself is not magnetic, but its associated minerals such as magnetite and hematite are magnetic), thus improving the separation effect. The drive component is used to rotate the screening cylinder 5, providing the power required for screening. Through the operation of the drive component, the screening cylinder 5 can rotate continuously, thereby realizing continuous screening operation.

[0022] In a further preferred embodiment of the present invention, the magnetic separation structure includes a screening box 10 fixed on the discharge cylinder 9, a magnetic separation roller 11 rotatably installed in the screening box 10 for separating mica, and a motor box 12 installed on one side of the screening box 10. The output shaft of the motor box 12 is connected to the magnetic separation roller 11, and the bottom of the screening box 10 is provided with a discharge port.

[0023] In this embodiment, the design of the secondary screening box 10 allows for further screening or processing of materials falling from the screening cylinder 5, especially for those materials that may still contain fine mica particles from scheelite powder. The magnetic separator 11 can adsorb and separate the magnetic mica particles. By rotating the magnetic separator 11, the mica particles adsorbed on the roller surface can be carried to a specific position, thereby achieving separation from the scheelite powder. The motor box 12 provides power to the magnetic separator 11, enabling it to rotate continuously and stably. The design of the motor box 12 ensures the efficient operation of the magnetic separator 11, thereby improving the magnetic separation efficiency. The design of the discharge port allows for adjustment of the discharge speed and direction as needed to meet different production requirements.

[0024] In a further preferred embodiment of the present invention, the driving assembly includes a driving roller 6 rotatably mounted on the inner wall of the top of the isolation box 3, a servo motor 7 fixed to the top of the isolation box 3, and a gear box 8 disposed inside the isolation box 3. The gear box 8 is connected to the output shaft of the servo motor 7 and the driving roller 6, and the gear box 8 is used for transmission.

[0025] In this embodiment, the drive roller 6 is a key component that drives the screening cylinder 5 to rotate. By rotating the drive roller 6, the screening cylinder 5 can be driven to rotate, thereby realizing the screening of materials. The servo motor 7 has the ability to precisely control the speed and direction of rotation, which can ensure that the drive roller 6 rotates at a stable speed and direction, thereby improving screening efficiency. The gear box 8 is used to transmit the power between the output shaft of the servo motor 7 and the drive roller 6. The gear box 8 contains multiple support wheels. Through the meshing and transmission of the support wheels, the rotational power of the servo motor 7 can be transmitted to the drive roller 6, and the speed and direction of rotation can be adjusted to meet the screening requirements.

[0026] In a further preferred embodiment of the present invention, an electric guide rail 14 is installed on the top of the base 1, and a collection box 15 for collecting minerals is sleeved on the moving part of the electric guide rail 14. An isolation plate 16 is installed inside the collection box 15 to divide the collection box 15 into a mica bin and a scheelite bin. The mica bin and the scheelite bin are used to collect mica and scheelite, respectively.

[0027] In this embodiment, the electric guide rail 14 provides guidance and power for the movement of the collection box 15. The design of the electric guide rail 14 allows the collection box 15 to move along a predetermined trajectory, facilitating the separate delivery of the screened material into the mica bin and the scheelite bin. The collection box 15 is used to collect the screened ore. The design of the collection box 15 allows it to move along with the electric guide rail 14, thereby enabling flexible delivery of materials into different storage areas. The design of the partition plate 16 ensures that the mica and scheelite can be stored separately in their respective bins, avoiding mixing and contamination.

[0028] In a further preferred embodiment of the present invention, both the isolation box 3 and the screening box 10 are provided with operating ports. The isolation box 3 and the screening box 10 are respectively hinged with a first protective plate 17 and a second protective plate 18 for closing the operating ports. Both the isolation box 3 and the screening box 10 are rotatably mounted with a clamping plate 19 for securing the first protective plate 17 and the second protective plate 18.

[0029] In this embodiment, the operating port provides operators with a passage to enter the chamber for maintenance, repair, or observation of material screening. The design of the operating port makes operation inside the chamber more convenient and safer. The first protective plate 17 and the second protective plate 18 are used to close the operating port. The design of the protective plates can prevent materials from splashing out of the operating port during screening, and can also prevent external dust and debris from entering the chamber, keeping the screening environment clean and stable. The clamping plate 19 is used to secure the first protective plate 17 and the second protective plate 18. The design of the clamping plate 19 allows the protective plates to be firmly fixed to the chamber, preventing them from loosening or falling off due to vibration during screening. At the same time, the clamping plate 19 also makes it easy for operators to quickly open or close the protective plates when needed.

[0030] In a further preferred embodiment of the present invention, a baffle 21 for closing the screening cylinder 5 is installed on the screening cylinder 5 by fixing bolts 20, the baffle 21 is provided with screening holes, and a guide plate 13 is installed inside the double screening box 10.

[0031] In this embodiment, the baffle 21 is designed to prevent material from leaking out from the side of the screening cylinder 5 during the screening process, ensuring that the material can be screened through the screening holes. At the same time, the baffle 21 can be opened when mica material needs to be discharged. The size and shape of the screening holes can be adjusted according to the characteristics of the material and screening requirements to achieve the separation of materials of different particle sizes. The guide plate 13 is designed to ensure that the material can flow out evenly and stably.

[0032] In a further preferred embodiment of the present invention, the motor box 12 consists of a protective shell for weakening and isolating electromagnetic signals and a reciprocating motor for driving the drive roller 6 to rotate, and the protective shell is sleeved on the reciprocating motor.

[0033] In this embodiment, the motor housing 12 consists of a protective shell and a reciprocating motor. The main function of the protective shell is to weaken or isolate the interference of electromagnetic signals on the motor and the surrounding environment. In situations where the electromagnetic environment is complex or where it is necessary to protect the motor from electromagnetic interference, the protective shell is particularly important. The reciprocating motor is responsible for driving the drive roller 6 to rotate. The reciprocating motor has the characteristics of compact structure, strong power and stable operation, which can meet the driving force requirements of the screening device. The presence of the protective shell effectively weakens the interference of electromagnetic signals on the motor and the surrounding environment, ensuring the stable operation of the screening device.

[0034] In summary, compared with related technologies, this device achieves effective separation of mica and scheelite through its structural design. The rotation of the screening cylinder 5 and the secondary separation by the magnetic separation structure ensure high efficiency and accuracy of the separation. At the same time, the design details of the drive components, collection box 15, and protective plate further enhance the stability and convenience of the device. This device has the advantages of simple structure, convenient operation, high screening efficiency, and good separation effect, and is suitable for industrial screening of mica and scheelite.
