Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, specifically a flexible sealing connection mechanism for a mineral processing vibrating screen. Background Technology

[0002] Vibrating screens are one of the commonly used pieces of equipment in mineral processing. They are used to classify and dewater materials. They are characterized by large amplitude and high vibration frequency. However, a large amount of dust is often generated during the operation and screening of vibrating screens. This dust not only pollutes the environment but may also threaten the health of workers. The existing sealing connection method of vibrating screens has problems such as inconvenience in transporting ore, poor separation of powder and crushed ore, inability to prevent dust, and reduction of the service life of the vibrating screen.

[0003] To address the aforementioned issues, several publications have emerged, including CN214262735U "A vibrating screen for mineral processing," which features an inclined screening box that allows ore to slide slowly down the screening plate at an inclined angle. The feed hopper ensures even distribution of ore at the screening end of the plate, and a conveyor belt below the screening plate quickly transports the screened ore out, preventing excessive accumulation that could hinder screening of the ore above the plate. The conveyor belt is connected to the screening plate, and a single drive motor enables both screening and transport, improving efficiency. CN222132551U "A vibrating screen for mineral processing" utilizes a fixing mechanism to secure the inclined plate and a sliding mechanism to limit the sliding of the plate when discharging mineral powder. This solves the problem of inconvenient manual separation of mineral powder and crushed ore during screening, where the powder is often separated from the crushed ore. However, neither of these two inventions has a dust removal function for the vibrating screen, making it difficult to extend the life of the mineral processing vibrating screen.

[0004] Therefore, it is of great significance to develop a flexible sealing connection mechanism for dust removal in mineral processing vibrating screens. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a flexible sealing connection mechanism for dust removal and sealing of a mineral processing vibrating screen. This mechanism can significantly improve the sealing performance of the vibrating screen, reduce dust pollution, and improve the working environment.

[0006] To accomplish the above tasks, this utility model adopts the following technical solution:

[0007] The flexible sealing connection mechanism for dust removal in mineral processing vibrating screens includes a vibrating screen body with an upper and lower layer. A dust cover with a dust removal duct extending into the vibrating screen body at one end and two smooth steel plates are installed on the top of the vibrating screen body. A flexible UT-type sealing device, mounting plate assembly, and fixing bolt assembly are installed on the outside of the vibrating screen body. Two angle steels and a fence funnel are provided at the bottom of the vibrating screen body. This effectively improves the sealing effect, extends the service life, and further reduces dust leakage.

[0008] Compared with the prior art, this utility model has the following advantages or effects:

[0009] Because the dust cover with a flexible UT-type sealing device is installed on the vibrating screen body, the sealing performance of the equipment and the service life of the soft connection are significantly improved. At the same time, because the vibrating screen body is equipped with a fence funnel, it can automatically collect dust inside, improving the working environment. In addition, due to its simple structure, it saves maintenance costs and time, making it easy to implement and maintain, and suitable for various mineral processing applications.
