Emergency device for detecting liquid level of material storage tank of cut stem feeding machine

Abstract

The invention discloses an emergency device for detecting the liquid level of a material storage tank of a cut stem feeding machine. The emergency device comprises the material storage tank, a main detection mechanism and an auxiliary detection mechanism. A detection opening is formed in the top of the material storage tank, and the main detection mechanism is arranged at the detection opening. The main detection mechanism comprises a sealing cover and a liquid level sensor, the sealing cover is in sealing connection with the detection opening, the liquid level sensor is fixed to the lower surface of the sealing cover, and the liquid level sensor extends into the material storage tank and detects the liquid level of liquid in the material storage tank. An opening is further formed in the side wall of the bottom of the material storage tank, the auxiliary detection mechanism communicates with the material storage tank through the opening, and the auxiliary detection mechanism detects the liquid level of liquid flowing into the auxiliary detection mechanism from the material storage tank. The detection value of the main detection mechanism is compared with the detection value of the auxiliary detection mechanism so as to avoid detection faults. The liquid level in the cut stem feeding machine is accurately detected in real time through the two detection mechanisms, and losses caused by faults of the liquid level detection mechanisms can be prevented.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to an emergency device for detecting the liquid level of a storage tank of a shredded stem feeder. Background technique [0002] The process of making tobacco leaves into cigarettes includes two major processes: silk making and cigarette rolling, tipping and packaging. In order to reduce the amount of tar in cigarettes, new technologies such as expanded shredded tobacco and perforated dilution have been widely used in cigarette technology. It is a process in the tobacco leaf processing process that the shredded stems are transported to the storage tank through the feeder for humidification, expansion and mixing in the shred workshop of the cigarette factory. The immersion liquid in the storage tank fully absorbs the fallen stems. In order to prevent the feeder from adding too much stalk material and to control the amount of humidifying liquid, a liquid level sensor is us...

AI Technical Summary

Problems solved by technology

However, when the liquid level sensor fails, the controller cannot correctly receive the liquid level signal in the storage tank, which will cause the controller to miscontrol the feeder and liquid pump, and for the operator, it is impossible to Understand and solve this fault. Only when the internal humidifying liquid is full out of the storage tank or the shredded stem material is added too much can it be discovered by the staff, but at this time, certain economic losses have been caused.
