Description

Technical Field

[0001] The utility model relates to the technical field of color sorters, in particular to a multi-layer blowing nozzle device for a color sorter. Background Art

[0002] The nozzle system is an essential component of a color sorter. It allows for the screening of different materials to meet sorting requirements. Currently, the nozzle assembly of a color sorter consists of a nozzle body and a nozzle cover, with the nozzle body having only a single layer of nozzle holes. Existing single-layer nozzle systems, due to their single-layer air outlet and limited air pressure, are only suitable for sorting lighter materials. For heavier materials, the single-layer nozzle outlet will not meet the sorting requirements. Using a high-pressure air jet valve would not only increase costs exponentially, but also make it difficult to achieve the desired results. Therefore, we propose a multi-layer nozzle assembly for color sorters. Utility Model Content

[0008] Beneficial effects

[0009] The utility model provides a multi-layer blowing nozzle device for a color sorter. It has the following beneficial effects:

[0010] (1) The color sorter uses a multi-layer blowing nozzle device. The gas enters the interior of the air inlet groove through the air inlet structure, then enters the interior of the air outlet through the guide port, and is then ejected through the air outlet groove. The direct connection range between the air outlet and the air outlet groove is adjusted by rotating the rotating column, so that the flow area of ​​the gas becomes smaller, and the pressure of the gas ejected is adjusted for flexible use.

[0011] (2) The color sorter uses a multi-layer blowing nozzle device. By rotating the rotating handle, the rotating handle drives the movable column to rotate, and the movable column drives the rotating handle to rotate. Then, by rotating the threaded column, the threaded column drives the extrusion block to squeeze the movable column, thereby restricting the movement of the movable column, further improving the stability of the rotating column during use.
