Description

Technical Field

[0001] The utility model belongs to the technical field of cigarette equipment, and in particular relates to a cigarette fan. Background Art

[0002] In cigarette production, the role of the positive pressure fan is to be a circulating fan that provides airflow for fluidized bed tobacco acceleration and primary sorting. The air inlet at one end of the positive pressure fan is connected to the upper mesh plate of the fluidized bed. The smoke dust flowing in from the mesh plate is removed by a cyclone dust collector and then enters the fan circulation. The cyclone dust collector cannot completely eliminate the smoke dust. The smoke dust circulates inside the fan and related pipes with the airflow. After being accelerated by the rotation of the fan blades, a large amount of frictional heat is generated between the smoke dust and the inner wall of the fan and the pipe wall, causing the temperature of the fan and the wind inside the pipe to rise to a certain critical value. If the fan temperature is at the critical value for a long time, the fan life will be shortened. At the same time, the increase in the fan temperature causes the airflow provided by the fan for fluidized bed tobacco acceleration and primary sorting to also have a high temperature. The moisture in the tobacco evaporates, and the moisture content of the tobacco decreases, causing the loss of cigarette flavor. Utility Model Content

Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work. In addition, the design orientation only represents the relative position relationship between the components, not the absolute position relationship.

[0026] The utility model embodiment provides a cigarette fan, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , mainly includes a fan body 1, a cooling part 2 and a heat exchange tube 3.

[0027] A cigarette blower provided by an embodiment of the utility model comprises a blower body 1 for providing airflow, a heat exchange tube 3 arranged on the surface of the blower body 1, a cooling part 2 arranged on the side of the heat exchange tube 3 away from the blower body 1, and a water pump connected to one end of the heat exchange tube 3; the cooling part 2 is used to fix the heat exchange tube 3 on the surface of the blower body 1, and the water pump is used to transport cold water to the heat exchange tube 3, and the heat exchange tube 3 exchanges heat with the inner space of the blower body 1.

[0028] Compared with the prior art, the tobacco powder is accelerated by the rotation of the fan blades, and a large amount of friction heat is generated with the inner wall of the fan and the pipe wall, so that the temperature of the wind inside the fan and the pipe rises to a certain critical value. The fan temperature is at the critical value for a long time, which will shorten the life of the fan. At the same time, the increase in the fan temperature causes the airflow provided by the fan for the fluidized bed tobacco acceleration and the primary sorting airflow to also have a high temperature, and the moisture in the tobacco evaporates, and the moisture content of the tobacco decreases, causing the loss of cigarette flavor. In the present application, by conveying cold water to the inside of the heat exchange tube 3 arranged on the surface of the fan body 1, the cold water inside the heat exchange tube 3 exchanges heat with the internal space of the fan body 1, thereby reducing the temperature of the fan, thereby increasing the service life of the fan, and avoiding the loss of moisture and flavor in the tobacco.

[0029] Furthermore, in order to enhance the efficiency of heat exchange between the heat exchange tube 3 and the inner space of the fan and strengthen the heat dissipation of the fan, the heat exchange tube 3 is a copper tube and the cooling part 2 is made of aluminum.

The water inlet pipe is connected to a water pump, and the water pump pumps water and then delivers cold water to the water inlet pipe. After the cold water flows through the first tube body 31 and the second tube body 32, it flows out from the water outlet pipe. When the cold water flows in the first tube body 31, the cold water inside the first tube body 31 exchanges heat with the internal space of the fan body 1, thereby reducing the temperature of the fan.

[0034] Specifically, the connector 33 includes a first connector block 331, a second connector block 332 and a connector sleeve 333; the first tube body 31 and the second tube body 32 are sleeved in the connector sleeve 333, the first connector block 331 is used to fix the first tube body 31, and the second connector block 332 is used to fix the second tube body 32. External threads are provided at both ends of the connector sleeve 333, and internal threads are provided in the first connector block 331 and the second connector block 332. Sealing rings 34 are provided at one end of the first connector block 331 and the second connector block 332 away from the connector sleeve 333. The sealing rings 34 are made of a flexible material and can be sleeved on the outer surfaces of the first tube body 31 and the second tube body 32 to prevent water leakage at the connection between the first tube body 31, the second tube body 32 and the connector 33. When connecting, first abut the first tube body 31 and the second tube body 32 against the inside of the connecting sleeve 333, and the first connecting block 331 and the second connecting block 332 are respectively screwed to different ends of the connecting sleeve 333.
