Description

Technical Field

[0001] This utility model relates to the field of screening devices, and in particular to a screening device for talc powder raw materials. Background Technology

[0002] The talc raw material screening device is a key facility in the production and processing of talc powder. Its function is to accurately screen the talc raw materials to remove impurities and separate particles of different sizes, thereby meeting the requirements of different industries for talc powder particle size and purity.

[0003] However, when the device is in use, it is usually set up as a single screening structure, which can only screen one type of coarseness. When it is necessary to increase the number of screening layers, it is also necessary to increase the number of screening barrels and the drive structure, which makes it inconvenient to use for screening different coarsenesses. Furthermore, when changing the screening coarseness of the screening barrel, it can only be changed to a single screening coarseness, and it is not possible to change to different screening coarsenesses, which also brings inconvenience to the use of screening different coarsenesses.

[0010] As a further embodiment of this utility model, the screening mesh barrel structure includes connecting mounting rods, a mesh cover frame, a mounting plate, and a screening mesh cover. Two connecting mounting rods are fixedly installed between the feeding drum and the discharging drum. Multiple mesh cover frames are attached to the front and rear ends of the connecting mounting rods. The mounting plate is fixedly installed at the upper and lower ends of the mesh cover frame, and the screening mesh cover is fixedly installed on the inner side of the mesh cover frame.

[0011] As a further embodiment of this utility model, the mounting plate rests on the upper and lower ends of the two connecting mounting rods and is fixedly connected by screws. The screen frame and the screening screen are arranged in a semi-circular shape, with each pair of screen frames and screening screens arranged symmetrically in front and behind. The conveying screw is located inside the screening screen.

[0012] Compared with the prior art, the present invention has the following advantages: the arrangement of two screening screens as a group constitutes a multi-screening screen installation structure, which can install screening screens with different mesh sizes for use, thereby performing multi-stage screening of talc powder raw materials, facilitating screening of different coarseness, improving screening effect and quality, and without increasing the overall drive structure and volume, making the device more convenient for screening.

[0013] The screen frame is installed using a mounting plate that passes through screws and connects to the mounting rod. After the screws on the mounting plate are removed, the screen frame and the screening screen can be quickly separated due to their separate structure, allowing for quick replacement and installation of the screening screen. This enables the screening size to be quickly changed according to screening needs, further facilitating screening of different coarsenesses. Attached Figure Description
