Lint cleaning airflow lint cleaning machine
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 collector through the converging pipe with the air flow.
Air flow type The 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 until 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 lower part of the machine is a row. Miscellaneous 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. Small when you reach 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 relaxation speed of the airflow gradually accelerates, reaching a maximum speed at the turning point. At the turning point, the fibers are lighter in weight and can turn upward with the airflow, while the impurities are heavier. The inertia is large and it is difficult to change the direction of play and continue to play forward. It will be thrown from the gap and fall into the auger or pit.
This 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 lint grade, the optimal size of the debris discharge slot opening is also different. The user can adjust it at any time according to the different lint grades to achieve the ideal debris removal effect.
The specifications of domestic MQPQ series and 6MQP series airflow (centrifugal) lint cleaning machines are shown in Table 10-1.
Air flow type (Centrifugal) lint cleaning machine has no leisure 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. It avoids the cotton particles and broken particles 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%.
