Description

Technical Field

[0001] The present application relates to the technical field of moisture removal filter structures, and in particular to a tobacco drum moisture removal filter scraper system. Background Art

[0002] The dehumidification filter of the tobacco drum plays a vital role in the tobacco processing process. It is mainly used to remove moisture generated in the drum and prevent debris from entering the dehumidification system to ensure the quality and production efficiency of tobacco products. During the tobacco processing process, tobacco leaf fragments, hemp fibers and other debris may enter the drum. The dehumidification filter can block these debris from entering the dehumidification system, prevent the system from being blocked, and ensure smooth dehumidification. If the filter is used for a long time, tobacco shreds and floating debris will adhere to the surface, which may easily cause the filter to be blocked.

[0003] The existing patent document "CN212697630U A Drum-type Tobacco Processing Equipment" discloses a tobacco processing equipment. In the above technical solution, a filter is provided on the rotating filter cylinder of the tobacco processing equipment to prevent clogging. However, during long-term use, due to the heating and processing of tobacco leaves, a certain amount of tobacco and floating debris mixed with impurities are easily attached to the filter, causing the filter to become clogged. At the same time, the tobacco and floating debris will be reinforced and fixed to the filter after cooling, making it difficult to stop the machine for cleaning.

There are several raised blocks 507, and the raised blocks 507 are fixed on the side wall of the circular plate 506 at equal intervals in a ring shape. When the connecting rod 30411 rotates, the circular plate 506 can be driven to rotate, thereby driving the raised block 507 to rotate. When the raised block 507 rotates and contacts the squeezing rod 505, the arc-shaped inclined surface of the raised block 507 will continue to squeeze the squeezing rod 505, thereby driving the squeezing rod 505 to move forward, thereby driving the slider 502 to move, and then driving the limiting slide plate 503 to move. Through the movement of the limiting slide plate 503, the front end of the limiting slide plate 503 can be further extended into the filter hole of the disc-shaped filter part 203, so that further conduction cleaning can be performed during scraping and cleaning. During the continuous rotation of the circular plate 506, the cleaning soft brush head 504 is automatically mobilized to reciprocate back and forth, thereby through the reciprocating back and forth motion of the cleaning soft brush head 504, the disc-shaped filter part 203 is fully conducted and cleaned, realizing the function of automatic scraping and cleaning.

[0068] The foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are readily apparent to those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application, which is defined by the appended claims.
