[0038] This embodiment provides a drum screen cleaning device that eliminates the need for manual cleaning of the drum screen 200, does not affect the normal operation of the wire drying equipment, and provides a more thorough cleaning of the drum screen 200. Figure 1 and Figure 2 As shown, the drum screen cleaning device includes a surrounding plate assembly 10, a drive assembly, and a steam nozzle 30. The surrounding plate assembly 10 includes at least two surrounding plates 11. The drive assembly can drive at least two surrounding plates 11 to approach the drum screen 200 to surround the drum screen 200. The drive assembly can also drive at least two surrounding plates 11 to move away from each other. At least one surrounding plate 11 is provided with a steam nozzle 30, which is configured to spray steam onto the drum screen 200.
[0039] The aforementioned drum screen cleaning device, through the arrangement of the surrounding plate assembly 10, wherein at least two surrounding plates 11 are driven to move closer or further away by the drive assembly. When the drying equipment is working normally, at least two surrounding plates 11 are in a far-away state, which does not affect the normal operation of the drum screen 200. When the drying equipment stops working at night, the drive assembly drives at least two surrounding plates 11 to move closer to each other, surrounding the drum screen 200. The steam nozzle 30 sprays high-temperature steam onto the drum screen 200, and grease, dust, etc. fall off the drum screen 200 under the action of steam, achieving the purpose of cleaning the drum screen 200. This process does not require manual operation and can be carried out unattended when the drying equipment needs to be stopped normally. The clean drum screen 200 can be used when the drying equipment is started the next day, without affecting the normal operation of the drying equipment during the day, and the cleaning effect is better.
[0040] The normal shutdown of the wire drying equipment refers to the fact that the wire drying equipment normally starts working in the morning and stops normally at night. At this time, there are no staff in the equipment room, and the drum screen cleaning device can clean the drum screen 200 at night.
[0041] It should be noted that after at least two surrounding plates 11 are fastened together, their inner sides are cylindrical to fit the shape of the drum screen 200. The outer shape is not limited. Both ends are open to avoid the drive elements at both ends of the drum screen 200 used to drive the drum screen 200 to roll. This part is a structure of the prior art and will not be described in detail here.
[0042] In this embodiment, as Figure 2 As shown, two surrounding plates 11 are provided, and the central angle of the side wall of each surrounding plate 11 is 180°. The driving assembly includes two driving components 21, which are arranged one-to-one with the two surrounding plates 11. The driving components 21 can drive the corresponding surrounding plate 11 to move closer to or away from the drum screen 200. On the one hand, the number of surrounding plates 11 is relatively small, which is convenient for manufacturing. Moreover, the fewer the number of surrounding plates 11, the smaller the gap when the surrounding plate assembly 10 is fastened, the better the sealing performance, and the more water vapor can be prevented from escaping. On the other hand, it can save on the number of driving components 21.
[0043] Optionally, in order to increase the airtightness of the enclosure panel assembly 10 when it is fastened, a sealing gasket is provided on at least one side of the adjacent enclosure panels 11. After fastening, the airtightness is greatly improved, thereby compensating for the positional deviation of the enclosure panels 11 during installation.
[0044] Optionally, the drive component 21 is a cylinder. Cylinders have the advantages of fast response and precise drive stroke.
[0045] Optionally, such as Figure 2 As shown, both surrounding plates 11 are equipped with steam nozzles 30. This arrangement allows for more comprehensive steam spraying and better cleaning results.
[0046] Optionally, such as Figure 2 As shown, each surrounding plate 11 is provided with at least two steam nozzles 30, and the at least two steam nozzles 30 are arranged at intervals along the axial direction of the surrounding plate 11. This arrangement can increase the uniformity of cleaning the drum screen 200 in the axial direction. In this embodiment, each surrounding plate 11 is provided with four steam nozzles 30. In other embodiments, the number of steam nozzles 30 on each surrounding plate 11 can be two, three or more, which is not limited here.
[0047] It should be noted that after the surrounding plate assembly 10 is fastened, there is still a certain gap between it and the drum screen 200, and the nozzle of the steam nozzle 30 is located at this gap.
[0048] Optionally, the inner side of the lowermost surrounding plate 11 forms a recess from the outside to the inside, and a flow hole is opened at the lowest point of the recess; the drum screen cleaning device also includes a drain pipe 40, which is connected to the lowermost surrounding plate 11 and the inlet of the drain pipe 40 corresponds to the flow hole. It is understood that due to the high temperature of steam, grease and other dirt are removed from the drum screen 200. If the recess and drain pipe 40 are not provided, the dirt flowing down will flow out from both ends of the snap-fit surrounding plate assembly 10, and the bottom surface or equipment will be contaminated. This arrangement can prevent dirt from polluting the external environment and facilitate the collection and discharge of dirt.
[0049] Optionally, such as Figure 1 As shown, the end of the drain pipe 40 near the flow hole is tapered. This design prevents dirt from clogging the inlet and facilitates the smooth flow of waste.
[0050] Optionally, the drum screen cleaning device also includes a steam generating assembly 50, which includes a steam pipeline 51 and a main steam valve 52. One end of the steam pipeline 51 is connected to the steam nozzle 30; the other end of the steam pipeline 51 is connected to the main steam valve 52, which is used to open or close the steam pipeline 51. The release and closing of steam are controlled by opening the main steam valve 52. It should be noted that the main steam valve 52 is an electronically controlled valve, such as a solenoid valve, controlled by a host computer, requiring no manual operation.
[0051] Preferably, a steam diaphragm valve 53 is provided on the steam pipeline 51. The steam diaphragm valve 53 can be opened and its opening degree can be adjusted to control the amount of steam discharged.
[0052] This embodiment also provides a tobacco drying device, including the aforementioned drum screen cleaning device. By employing the drum screen cleaning device, the drying device achieves better cleaning of the drum screen 200 and increases the drying speed of the tobacco.
[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
