Flushing control method and device for station of bottle washing machine

Abstract

The invention discloses a method and device for controlling washing of a station of a bottle washing machine. According to the method for controlling washing of the station of the bottle washing machine, when a central control unit confirms that a bottle or a bucket is placed on the station according to information fed back by a detecting device, a station valve, corresponding to the station, on a washing pipeline is controlled to be opened, a corresponding water pump on the washing pipeline is controlled to operate at a high speed, and a spraying head on the station is made to wash the bottle or the bucket in a spraying mode; when the central control unit confirms that no bottle or bucket is placed on the station, the station valve is controlled to be closed, the water pump is controlled to operate at a low speed, and the spraying head is made to stop washing. The device for controlling washing of the station of the bottle washing machine comprises the central control unit, the detecting device, the station valve, the water pump, the spraying head and the washing pipeline, wherein the detecting device, the station valve and the water pump are connected with the central control unit electrically, and the water pump, the station valve and the spraying head are installed on the washing pipeline in sequence in the flowing direction of water in the washing pipeline. The method and device for controlling washing of the station of the bottle washing machine has the advantages that energy consumption, water consumption and acid and alkali water consumption can be reduced and the phenomenon of leakage of the station is avoided.

Description

technical field [0001] The invention relates to a method and device for controlling flushing of a station of a bottle washing machine. Background technique [0002] In the station flushing control of the existing bottle washing machine, a two-position three-way reversing valve is usually used for control. The first interface of the above-mentioned reversing valve is connected to the water outlet of the water pump, the second interface is connected to the spray flushing pipeline, and the third interface passes through The pipeline is connected with the water tank, the spray flushing pipeline is a part of the flushing pipeline, and a nozzle is installed on the spray flushing pipeline. The working process of station flushing control is as follows: every time the bottle washing machine goes to a station, the reversing valve is switched to connect with the spray flushing pipeline. Water flushing, when the bottle or bucket is moving between two adjacent stations, the reversing va...

Problems solved by technology

Therefore, in the existing flushing control of the station of the bottle washing machine, since the water pump is always in the working state of high-speed operation, the service life of the water pump is shortened and the energy consumption is high. In addition, when the station is flushed without a bottle or barrel, it is easy to consume Water and water channeling occurs at the station, and because bottle washing is divided into acid water rinse, alkaline water rinse, finished product reflux rinse and finished product rinse, if there is no bottle or barrel rinse, it is easy to cause acid and alkali liquid to channel and the acid and alkali concentration to decrease , in the case of ensuring that the acid-base concentration of flushing remains unchanged, the consumption of acid-base solution is more
