Technical Field

[0001] The utility model relates to the technical field of spraying devices, in particular to a flash evaporator feed steam lock screen spraying device. Background Art

[0002] In actual production, a large amount of induced steam will continue to pass through the feed hood of the flash steam lock to heat and humidify the shredded stems. A filter is provided at the open end of the bottom of the feed hood. When the dehumidification system is started, a large amount of wet shredded stems will adhere to and gather on the surface of the screen under the action of the dehumidification wind, causing the screen to be frequently blocked, greatly reducing the dehumidification effect. At the same time, it is time-consuming and laborious for the operator to clean the screen.

[0003] And in the application document with announcement number CN217794577U, a flash evaporator feed steam lock screen blowing device is mentioned. The blowing device achieves unobstructed operation by blowing on the screen to avoid the accumulation of moist stems and the blocking of the screen, thereby greatly improving the dehumidification effect and avoiding the formation of wet clumps of stems, improving the quality of finished stems, and reducing the difficulty of operators in cleaning and maintaining the screen, which effectively solves the above problems. However, there are still certain defects and deficiencies that need to be improved, as follows: the blowing pipe of the blowing device is designed as an annular structure surrounding the inner wall of the feed hood. Then, during the blowing process, the blowing force of the screen near the center of the circle is much smaller than that of the surrounding area of ​​the screen, and the screen near the center of the circle cannot be guaranteed to be unobstructed, which is prone to blockage and is not conducive to dehumidification.

[0004] Therefore, it is necessary to design a flash evaporator feed steam lock screen blowing device to solve the problems in the above background technology. Utility Model Content
