Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco manufacturing, and in particular relates to a self-cleaning device for a filter screen of a discharging cover of a flavoring and feeding drum. Background Art

[0002] At present, in the field of cigarette production, the discharging hood of the flavoring and feeding drum on the silk making line is generally equipped with a dehumidification system, and a filter is provided at the front end of the system. The main function of the filter is to prevent the exhaust gas and dust mixture from adhering to the fan impeller, causing the fan to operate unbalanced and then damage the fan. The main responsibility of the dehumidification fan is to remove the dust and exhaust gas generated in the drum, while the filter plays the role of blocking the large amount of dust and exhaust gas generated by the nozzle atomizing flavors and spices and the tobacco leaves and tobacco shreds rolling in the barrel during the production process. It is worth noting that some flavor and fragrance mixtures have extremely strong adhesion. They will adhere to the flat filter screen with a size of 400×300mm set in the pipeline, which will seriously affect the suction and air permeability of the exhaust gas in the drum, resulting in reduced uniformity of tobacco shreds to absorb flavors and spices and unstable outlet moisture. These factors are very likely to cause quality accidents. In addition, this will also affect the negative pressure in the drum, causing the aroma to leak out, which will have an adverse effect on the production environment of the workshop. At present, this flat filter needs to be cleaned every day, which undoubtedly increases the labor intensity of employees. Utility Model Content
