Embodiment Construction

[0026] 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;

[0027] Such as Figure 2-3 As shown, the present invention provides a method for automatic dredging of pipe plugging detection in wind power feeding system and a kind of automatic dredging system for pipe plugging detection. The automatic dredging system for pipe plugging detection includes a controller and a motor. The frequency is controlled and adjusted, and the motor is connected to the fan; the controller is connected to the regulating valve arranged between the wrapping machine and the dust removal equipment through a signal line, and the controller performs signal adjustment and control on the regulating valve; The Venturi flowme...

Abstract

The invention discloses an automatic dredging method for detection of pipe blockage in a wind feeding system, which detects the wind speed of the wire feed pipe in real time, and combines the change rule of the wind speed of the blockage of the wire feed pipe to judge whether the pipe is blocked and the location of the blockage, and if the blockage occurs, immediately increase the operation of the fan Frequency and increase the opening of the regulating valve on the blocked pipe to increase the air volume to clear the blockage; if it is multi-pipe transportation, it can also be adjusted down or closed to increase the suction of the blocked pipe; when the wind speed of the blocked pipe returns to normal , restore the opening of each regulating valve, and restore the normal operating frequency of the motor. The invention closely tracks the change of wind force, timely and accurately judges the blocked pipe, and automatically clears the blocked part in time, reduces manual intervention, prevents the wrapping machine from dropping material due to blocked pipe, and improves the automation and reliability of the wind power wire feeding system.

Description

technical field [0001] The invention belongs to the technical field of cigarette production, specifically relates to the field of wind feeding, in particular to an automatic dredging method and system for detecting pipe blockage in a wind feeding system. Background technique [0002] The wind feeding system uses the principle of negative pressure suction to transport materials from the feeding point to the using point. Tobacco companies mainly use it in the wind wire feeding link, that is, the wind wire feeding system. The pneumatic wire feeding system consists of two parts: tobacco feeding and dust removal, including wire feeding machine, wire feeding pipe, Venturi flow meter, regulating valve, return air pipe, dust removal equipment, fan, controller, human-machine interface, etc. Venturi flowmeter has relatively small additional resistance to flow and good stability. The most important thing is that it is suitable for flow measurement with more impurities. Wind wire feedin...
