Control method for reducing cut tobacco drying amount and energy consumption in cut tobacco making and drying section

Abstract

The invention discloses a control method for reducing cut tobacco drying amount and energy consumption in a cut tobacco making and drying section, and relates to the technical field of electrical control. The control method for reducing cut tobacco drying quantity and energy consumption in a cut tobacco making and drying section realizes different control on the conveying speed of cut tobacco conveying equipment by performing frequency conversion control, normal speed state, acceleration state and idling state on all the conveying equipment in the cut tobacco drying section. A normal speed state is adopted during normal production, and an acceleration state is adopted when stub bars and tail tobacco shreds pass through a processing section, so that the amount of dry shreds at an outlet ofthe cut tobacco dryer is reduced, the time consumed in the whole batch production process is shortened, and similarly, an idling state is adopted in a standby state, the operation frequency of conveying equipment is reduced, and the energy consumption of the conveying equipment during waiting is reduced. The method is helpful for reducing the material consumption and energy consumption of the whole cut tobacco making and drying section, is a new method for electrically controlling the cut tobacco drying section, and is more in line with the efficient and lean requirements of modern cigarettes.

Description

technical field [0001] The invention belongs to the technical field of electric control in the silk making and drying section of the cigarette industry, and in particular relates to a control method for reducing the amount of dry silk and energy consumption in the silk making and drying section. Background technique [0002] In the cigarette shred production line, in order to ensure the stability and continuity of feeding, and to avoid that once a feeding failure occurs in the cutting section, it will affect the drying section. The drying section needs to wait for the buffer bin to be filled to a certain extent before production. The material production has just started, but in this process, due to the technical requirements of the hot air of the silk dryer to reach a certain value, and in order to avoid a large amount of condensed water when the bulking machine starts, the host equipment needs to be started and preheated in advance. At this time Auxiliary equipment is in a ...
