Description

Technical Field

[0001] This utility model relates to the technical field of cigarette processing equipment, and more specifically to an online cleaning device for the dehumidification pipeline of an energy-saving airflow drying machine. Background Technology

[0002] The airflow drying machine is one of the main pieces of equipment in the tobacco processing workshop, primarily used for drying and dehydrating tobacco shreds. The exhaust pipe is used to remove dusty, humid, and hot air generated during the airflow drying process from the drying system. During operation, dusty, humid, and hot air easily adheres to the bends and inner walls of the exhaust pipe. As the buildup increases, the exhaust volume decreases, the dehumidification effect deteriorates, and consequently, the control of the moisture content at the material outlet is affected. Currently, the exhaust pipe is typically cleaned by periodically disassembling it. This method is not only inefficient and labor-intensive, but also poses a significant safety hazard due to the risk of falls from heights, negatively impacting production and maintenance personnel. Utility Model Content

[0014] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0015] See Figures 1 to 2 This embodiment discloses an online cleaning device for the dehumidification pipeline of an energy-saving airflow drying machine. The dehumidification pipeline is set above the discharge vibrating trough of the airflow drying machine. The dehumidification pipeline includes a horizontal pipeline 1 and multiple vertical pipelines 2. The multiple vertical pipelines 2 are spaced below the horizontal pipeline 1 and connected to the horizontal pipeline 1. Each vertical pipeline 2 is provided with a dehumidification hood 3 at its lower end.

[0016] The online cleaning device includes a condensate tank 4, with an inlet pipe 5 at the top, which connects to the condensate drain pipe of the airflow drying machine. An outlet pipe 6 at the bottom of the condensate tank 4 connects to a cleaning pipeline system, which includes a centrifugal pump 7, a cleaning water pipeline 8, and a jetting pipeline 9. The inlet of the centrifugal pump 7 is connected to the outlet pipe 6 of the condensate tank 4. The outlet pipe 6 of the condensate tank 4 splits into two branches: one branch connects to the inlet of the centrifugal pump 7 via an inlet pipe 10, and the other branch is a direct discharge pipeline 16. The inlet pipe 10 is equipped with a cleaning water valve 11, and the direct discharge pipeline 16 is equipped with a direct drain valve 12. The direct discharge pipeline 16 can be connected to a drainage ditch. The outlet of the centrifugal pump 7 is connected to the inlet of the cleaning water pipeline 8 via a centrifugal pump outlet pipe 13. The inlet pipe 10 and outlet pipe 13 are connected to the inlet and outlet of the centrifugal pump 7 respectively via flange connections.

[0017] The outlet of the cleaning water pipe 8 extends into the horizontal pipe 1 of the dehumidification pipe and is connected to the spray pipe 9. The spray pipe 9 is located in the horizontal pipe 1 of the dehumidification pipe and extends in the same direction as the horizontal pipe 1. The spray pipe 9 is equipped with nozzle assemblies at the corresponding positions of each vertical pipe 2. The horizontal pipe 1 and the vertical pipe 2 are cleaned by spraying through the nozzle assemblies.

[0018] The nozzle assembly includes a first nozzle 14 and a second nozzle 15 respectively disposed on the blowing pipe 9. The first nozzle 14 extends obliquely upward toward the inner wall of the horizontal pipe 1 for cleaning the inner wall of the horizontal pipe 1, and the second nozzle 15 extends obliquely downward toward the inner wall of the vertical pipe 2 for cleaning the inner wall of the vertical pipe 2. The first nozzle 14 and the second nozzle 15 are respectively installed on the blowing pipe 9 by means of threaded connection.

[0019] When cleaning of the drainage pipes is required, the centrifugal pump 7 is started, and the cleaning water valve 11 is opened. The water in the condensate tank 4 is pressurized by the centrifugal pump 7 and then delivered to the nozzle assembly. The cleaning water is sprayed onto the inner wall of the drainage pipes through the first nozzle 14 and the second nozzle 15 to remove the soot and dust adhering to the inner walls of the horizontal pipes 1 and the vertical pipes 2. The cleaned wastewater falls down the drainage hood 3 into the discharge vibrating trough below, then flows out along the inclined discharge vibrating trough and is discharged into the ditch through the pipes, thus cleaning the drainage pipes.

[0020] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
