Embodiment Construction

[0034] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer definition of the protection scope of the present invention;

[0035] Such as Figure 2-3 As shown, the present embodiment is as follows to the method for lean control of fan wind power in tobacco enterprises:

[0036] The invention relates to an energy-saving and lean control method for wind-forced wire-feeding. Through in-depth analysis of the operating characteristics and process requirements of the wind-forced wire-feeding system, the changing law of the wind-forced wire-feeding working condition is found out. Determine the main frequency of motor operation according to the number of wrapping units in operation, and then determine the fine-tuning motor frequency according to the different mater...

Abstract

The invention discloses an energy-saving lean control method for air tobacco supply. The method comprises the following steps of finding out the law of changes of operating conditions of the air tobacco supply through deeply analyzing the operating characteristics and process requirements of an air tobacco supply system; determining the operating principal frequency of a motor according to the operating number of roll-packing units, and then determining a fine adjustment motor frequency according to different feeding conditions of various operational roll-packing units, motor adjusting properties and system-allowed adjustment waiting time; finally adjusting a draught fan operation frequency to realize lean control of air force under different operating conditions according to the corresponding relation. In order to realize fast feeding of the roll-packing units and adjustment of the air force and reduce mutual interference between the roll-packing units, the air quantity of a feeding branch pipe can be stopped through compensation of an air compensating valve, the air force of a main pipe network can be basically balanced through adjusting the air quantity compensated by the air compensating valve, thereby making up for the compensation that air force fluctuation is caused as a motor cannot realize rapid adjustment by a large margin.

Description

technical field [0001] The invention belongs to the technical field of cigarette production, in particular to an energy-saving and lean control method for wire feeding by wind. Background technique [0002] The pneumatic wire feeding system uses the principle of negative pressure suction to transport the shredded tobacco from the wire feeding machine at the wire feeding station to the shredded tobacco distribution bin of the wrapping machine. The pneumatic wire feeding system consists of two parts: tobacco feeding and dust removal, including wire feeding machine, wire feeding pipe, Venturi flowmeter, regulating valve, return air pipe, dust removal equipment, fan, controller, man-machine interface, etc. figure 1 shown. [0003] Usually one fan provides wind power to multiple wrapping machines, and most of them are driven by soft starters and frequency converters and run at a fixed frequency. In the design stage, the fan is selected according to the maximum load and a certai...
