The airflow lint cleaning machine is also called the centrifugal lint cleaning machine. It is installed at the lint outlet of each sawtooth gin. The lint is cleaned and then sent to the lint collecting machine through the collecting pipe with the air flow.
The airflow lint cleaning machine is shown in Figure 10-1. This lint cleaning machine does not have saw blades, brushes or other rotating parts, but only a horizontal to vertical pipe. The diameter of the pipe gradually decreases inward from the entrance of the lint to the minimum when it reaches the turning point. At the bottom of the turning point, there is a long and narrow notch. There is an adjustment plate on the upper part of the notch to adjust the opening of the notch. The bottom part of the machine is Trash auger.
During cleaning, the loose lint rolled out by the sawtooth gin is blown into the lint pipe of the airflow lint cleaning machine by the airflow of the gin brush. The cross-sectional area of the lint pipe of the airflow lint cleaning machine gradually becomes smaller from the entrance. Minimum when reaching the turning point of the lint road. After turning, it gradually becomes larger upwards. There is a flat and narrow gap at the turning point of the lint road. The width of the gap can be adjusted through the adjustment mechanism. The fibers enter the airflow lint cleaning machine with the airflow. From the entrance to the turning point, the movement speed of the airflow gradually accelerates and reaches the maximum at the turning point. At the turning point, the fibers are lighter in weight and can turn and move upward with the airflow, while the impurities are heavier. The inertia is large and it is difficult to change the direction of movement and continue to move forward. It will be thrown from the gap and fall into the auger or pit.
The machine has two adjustable parts. One is by adjusting the position of the lint support plate, the cross-sectional area at the turning point of the lint road can be adjusted, thereby changing the wind speed of the lint at the turning point and controlling the removal of impurities. The adjustment range here is 30~50mm, under normal circumstances, it is fixed at 40mm, that is, the middle position is ideal; the other adjustable part is to adjust the size of the debris discharge slot through the adjustment handle, and the adjustment range is 15~40mm. Depending on the grade of lint, the optimal size of the opening of the trash discharge slot is also different. The user can adjust it at any time according to the different grades of lint to achieve the most ideal trash discharge effect.
The specifications of domestic MQPQ series and 6MQP series airflow (centrifugal) lint cleaning machines are shown in Table 10-1.
The airflow (centrifugal) lint cleaning machine has no moving parts that affect cotton fibers, so it is the only lint cleaning machine that does not cause damage to cotton fibers. It does not require power itself and has a simple structure. It can effectively remove large particles of impurities such as cotton seeds, infertile particles, and broken particles in the lint, preventing the cotton particles and broken particles from being pulled and crushed when the lint passes through the sawtooth lint cleaning machine. into multiple defects. The impurity cleaning rate of the airflow lint cleaning machine is about 20%.
