Description
Technical Field
[0001] The utility model relates to the field of tobacco processing, in particular to an air supply and blanking device for a cut stem air separator. Background Art
[0002] Cut stem air separation is a crucial process in the stem production line. Its purpose is to properly cool the cut stems exiting the stem drying machine and remove any impurities, ultimately producing relatively pure cut stems. The working principle of a cut stem air separator is to utilize airflow to separate the material. The airflow generates inertia in the material, which changes its state of motion, thereby separating impurities and harmful substances. The material's motion in the airflow depends on factors such as its density, shape, and size. Impurities and harmful substances are separated because of their different density, size, and other characteristics.
[0003] The main factors determining the effectiveness of shredded stem air separation include the uniformity of the feed and the uniformity of the airflow within the air separation chamber. Traditional shredded stem air separators have four air supply ports. This has the disadvantage that, due to the square-conical shape of the discharge port, air supply vortices are easily generated at the angles. Furthermore, the four ports can cause uneven airflow, affecting the air separation effect. Summary of the Invention

DETAILED DESCRIPTION
[0022] like Figure 1As shown, the present invention discloses a wind-supplying and blanking device for a cut stem air separator, comprising: a vibrating trough conveyor 1, a cyclone separator 2, a cut stem discharge pipe 4, a lower stem pick discharge head 8, a stem pick feed pipe 9, a bracket 12, a suction pipe 13, a dust collector 16, and a centrifugal fan 18. The upper end of the cyclone separator 2 is connected to the lower end of the upper stem discharge head 20 via an upper stem discharge flange 5 and a lower stem discharge flange 19. The upper end of the upper stem discharge head 20 is connected to the cut stem discharge pipe 4. A cut stem collection box 11 is positioned at the outlet of the cut stem discharge pipe 4. One end of the suction pipe 13 is connected to the outlet of the cut stem discharge pipe 4, and the other end is connected to one side of the dust collector 16. An explosion-proof valve 14 and a fire damper 15 are installed on the suction pipe 13 in this order. A dust box 17 is positioned at the outlet of the dust collector 16. A centrifugal fan 18 is connected to the other side of the dust collector 16. The lower end of the cyclone 2 is connected to the upper end of the stalk discharge lower end cap 8 via the upper and lower flanges 6 and 7. A sealing gasket 21 is installed between the upper and lower flanges 6 and 7. The lower end of the lower end cap 8 is connected to the stalk feed pipe 9, at the outlet of which a stalk collection box 10 is placed. The cyclone 2 has a feed port 3, and a vibrating trough conveyor 1 is supported by a bracket 12. The outlet of the vibrating trough conveyor 1 is connected to the feed port 3. The lower end cap 8 is characterized by an inverted conical shape, with 1-3 mm circular holes drilled into the thin wall, with 100-300 holes per square meter.
[0023] like Figures 2 to 7 As shown, the wind supply and blanking device of the shredded stem air separator also includes: 8-12 quick-install devices installed on the circumference of the upper flange 6 and the lower flange 7 of the stalk discharge, which are evenly installed on the circumference of the upper flange 6 and the lower flange 7 of the stalk discharge, and the quick-install devices include: a fixed hook 22, a handle 23, a crank bracket 24, a rotating shaft 25, a hook 26 and a crank 27, the fixed hook 22 is evenly installed on the circumference of the upper flange 6 of the stalk discharge, and the crank bracket 24 is installed on the stalk corresponding to the fixed hook 22. On the circumference of the lower discharge flange 7, one end of the two cranks 27 is hinged to the crank bracket 24 through the hinge shaft 28, and rotates around the hinge shaft 28. The rotating shaft 25 passes through the inflection point of the two cranks 27. The open ends of the door-shaped hook 26 are respectively mounted on the two ends of the rotating shaft 25, and the two handles 23 are respectively mounted on the other end of the crank 27. Moving the handle 23 causes the crank 27 to rotate around the hinge shaft 28, and at the same time the hook 26 rotates around the rotating shaft 25, and its other end is hung on or detached from the fixed hook 22.
[0024] After redrying, the shredded stems pass through a vibrating trough conveyor 1, through a feed port 3, and into a cyclone 2. Centrifugal fan 18 creates a negative pressure in the cyclone, and under this rising negative pressure, the shredded stems flow through a stem discharge pipe 4 and into a stem collection box 11. Due to their own weight, the stems pass through the stem discharge lower seal 8 and the stem feed pipe 9, and into the stem collection box 10. Because the stem discharge lower seal 8 is inverted conical and has small circular holes, air supply is eliminated from generating vortices at the corners, further improving air supply uniformity and enhancing the quality of the stem separation. A quick-release device allows for rapid opening of the stem discharge lower seal 8.
[0025] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
