The airflow equalization device includes an air inlet pipe, an air inlet pipe guide plate, an equalization device housing, a movable guide plate, an adjusting screw, a fixed guide plate, a mesh plate, an upper flap door, a lower flap door, an upper flap door cylinder, and a lower flap door cylinder. After passing through the air inlet pipe, the airflow flows more evenly to the mesh plate under the action of the movable guide plate. The mesh plate further evenly distributes the airflow into the equalization device housing. Simultaneously, the alternating opening of the upper and lower flap doors discharges objects that cannot be effectively suspended by the airflow, preventing airflow exchange between the outside and the housing. This utility model, by adding an adjustable movable guide plate and double-layer flap doors, allows the airflow to enter the equalization device housing more evenly, while the double-layer flap doors ensure the stability of the airflow inside the equipment and isolate dust.

Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, and in particular to an airflow equalization device for a pneumatic impurity removal machine. Background Technology

[0002] Most known tobacco cleaning equipment does not use air guide plates or uses fixed air guide plates, resulting in poor airflow uniformity. It is also difficult to effectively regulate uneven airflow in the later stages. Furthermore, objects that cannot be effectively suspended by the airflow are discharged from the equipment through open openings, resulting in a large amount of dust, which is detrimental to the health of employees. The presence of openings also causes airflow turbulence inside the equipment, affecting the uniformity of airflow and thus impacting the overall performance of the equipment. Summary of the Invention

[0003] The problem this invention aims to solve is that the equipment has poor airflow uniformity, cannot effectively adjust uneven airflow in the later stages, and the open opening causes a large amount of dust, resulting in turbulent airflow at the opening, which affects the uniformity of airflow inside the equipment and the overall performance of the equipment.

[0004] To solve the above problems, the present invention adopts the following solution: an airflow equalization device for a pneumatic impurity remover, characterized in that the airflow equalization device includes an air inlet pipe, an air inlet pipe guide plate, an air equalization device housing, and a mesh plate; the air equalization device housing is composed of an inner side plate, a bottom plate, an outer side plate, and an end plate connected to form a housing with two air distribution channels and one impurity discharge channel, and the impurity discharge channel is located between the two air distribution channels; four air inlet pipes are provided, respectively arranged on both sides of the air equalization device housing, and connected to the two ends of the air distribution channels of the air equalization device housing; the air inlet pipe guide plate is inside the air inlet pipe, dividing the air inlet pipe into multiple air distribution channels; a mesh plate is provided at the air outlet of the air distribution channel. Multiple air inlet pipe guide plates are provided inside the air inlet pipe, and the airflow enters the pipe from the air inlet, where it is divided into multiple airflow streams under the action of the air inlet pipe guide plates.

[0005] Furthermore, the airflow equalization device for the pneumatic impurity remover is characterized in that a fixed guide plate and a movable guide plate are provided inside the air distribution duct of the device housing; the fixed guide plate is located in the center of the air distribution duct, and the movable guide plates are located on both sides of the fixed guide plate for connecting to the air inlet pipe; the movable guide plate includes a short adjustable plate and a short adjustable inclined plate, which are connected by a hinge; the short adjustable inclined plate is fixedly connected to the inner wall of the device housing; an adjusting screw is provided on the short adjustable plate, and the end of the adjusting screw is located on the bottom plate; the adjusting screw can adjust the up and down movement of the short adjustable plate. The movable guide plate can be adjusted by adjusting the screw to divide the airflow into multiple airflows, causing the airflow to flow towards the perforated plate.

[0006] Furthermore, the airflow equalization device for the pneumatic impurity remover is characterized in that the perforated plate is installed obliquely at the air outlet of the air distribution duct, with the lower part of the perforated plate connected to the inner side plate and the upper part connected to the outer side plate. The perforated plate is made of perforated material, and the airflow, after initial distribution by the movable guide plate, will be further evenly distributed in the perforated plate area, allowing the airflow to pass through the perforated plate more uniformly into the housing of the equalization device. Furthermore, by installing the perforated plate obliquely, while guiding and diverting the airflow, objects that cannot be effectively suspended by the airflow can slide down the inclined surface to the flip door.

[0007] Furthermore, the airflow equalization device for the pneumatic impurity removal machine is characterized in that an upper flap door and a lower flap door are respectively provided on the upper and lower sides of the impurity discharge duct of the device housing. An upper flap door cylinder assembly is connected to one side of the upper flap door, and a lower flap door cylinder assembly is connected to one side of the lower flap door. The upper and lower flap doors are driven to open and close by the upper and lower flap door cylinders respectively. The upper and lower flap doors are located between the two sets of inner side plates to lock the internal airflow while discharging objects that cannot be effectively suspended by the airflow.

[0008] The technical effects of this invention are as follows: This design, by adjusting the screw to adjust the movable guide plate, allows the airflow to flow more evenly towards the perforated plate. The perforated plate further evenly distributes the airflow into the housing of the air distribution device. Simultaneously, the alternating opening of the upper and lower flap doors discharges objects that cannot be effectively suspended by the airflow while isolating the external airflow from the internal airflow. This prevents dust from entering the working environment and avoids external airflow affecting the internal airflow. This method avoids excessive dust accumulation in the equipment and also prevents external airflow from influencing the internal airflow, improving the stability of the internal airflow and ensuring the stable operation of the equipment.

The air distribution device housing 3 includes an inner side plate 10, a bottom plate 11, an outer side plate 12, and an end plate 13. The movable guide plate 4 and the fixed guide plate 6 are inside the air distribution device housing 3, positioned between the inner side plate 10 and the outer side plate 12. The lower part of the adjusting screw 5 is connected to the bottom plate 11, and the adjusting screw 5 passes through the movable guide plate 4, allowing the movable guide plate 4 to be adjusted up and down via the adjusting screw 5. The lower part of the mesh plate 7 is connected to the inner side plate 10, and the upper part is connected to the outer side plate 12. The mesh plate 7 is installed at an angle.

Then the upper flap door cylinder 14 drives the upper flap door 8 to close, and the lower flap door cylinder 15 drives the lower flap door 9 to open, expelling the objects from the equipment. The lower flap door cylinder 15 drives the lower flap door 9 to close.
