Description

Technical Field

[0001] The utility model relates to the relevant field of screening devices, in particular to a feeding and screening device of a dust-free feeding station. Background Art

[0002] The dust-free feeding station is a manual device used to manually dump small bags of powder or granular materials into the downstream hopper. It completes the bag unloading and unloading work by manually unpacking the bag and automatically dumping the material so that the material falls into the storage hopper by gravity. The filter cleaning device and exhaust fan are installed inside the equipment to filter out the dust generated during the dumping process and discharge the clean exhaust gas into the atmosphere, so that workers can work easily in a clean environment.

[0003] The utility model patent with publication number CN 214391027 U in the prior art proposes a feeding and screening device for a dust-free feeding station, which is provided with a cam and a movable rod. The rotation of the cam drives the movable rod to move up and down, and then drives the screen to move up and down, so as to screen the raw materials. At the same time, the up and down movement of the screen can prevent the screen from being blocked, thereby improving the screening efficiency. The agglomerated raw materials are screened to both sides of the screen by the screen. When the screen rises, the agglomerated raw materials are driven to contact with the extrusion plate to extrude the agglomerated raw materials. However, the efficiency of crushing the raw materials by extrusion is low and the crushing effect is not good, which easily causes large pieces of raw materials to fall directly from both sides or the agglomerates to be stronger after extrusion, making it difficult to carry out subsequent processing operations. At the same time, it does not have the effect of quickly replacing and disassembling the screen, and the device is difficult to adapt to different work requirements. Therefore, we need to upgrade and transform the existing technology to overcome its problems and shortcomings. Utility Model Content
