Safety protection system of bottle washing machine

Abstract

The embodiment of the invention provides a safety protection system of a bottle washing machine. An alkali tank, an alkali pump and filter screen devices of the bottle washing device are communicatedin sequence. A through hole is formed in the side wall of the alkali tank. A temperature detection probe penetrates the through hole, and one end of the temperature detection probe is arranged in thealkali tank and used for detecting the temperature of alkali liquid in the alkali tank. A proximity switch is arranged outside each filter screen device, and each proximity switch is aligned to the side face of a top cover of the corresponding filter screen device and used for detecting the opening/closing state of the corresponding top cover. A pressure measurement instrument is connected to an outlet pipeline of each filter screen device and used for detecting the pressure of liquid in the corresponding pipeline. A control system is used for receiving data of the temperature detection probe,the proximity switches and the pressure measurement instruments and comparing the data with a preset range value of the system. Thus, when the temperature of the alkali liquid of the alkali tank andthe pressure of alkali liquid of liquid outlets of the filter screen devices are out of the set range or the top covers of the filter screen devices are opened in the bottle washing machine, the bottle washing machine can be shut down automatically so as to ensure safety in the production process, meanwhile, the bottle cleaning and sterilization function can be ensured, and the bottle washing quality can be improved.

Description

technical field [0001] The invention relates to the technical field of cleaning equipment, in particular to a safety protection system for a bottle washing machine. Background technique [0002] The bottle washing machine is a common cleaning equipment on the beer production line, which includes multiple mechanisms and multiple processes. Among them, the alkali tank is used to store lye to soak the cleaned recovery bottle; the liquid inlet of the alkali pump is connected with the alkali tank, the liquid outlet of the alkali pump is connected with the liquid inlet of the filter device, and the filter device Used to filter impurities in lye. [0003] In the actual cleaning process, the temperature of the lye in the alkali tank is an important factor affecting the cleaning of the recovery bottle. If the temperature is too low, it is not easy to clean the recovery bottle, and if the temperature is too high, it will easily cause waste of resources; for the filter device, due to ...

AI Technical Summary

Problems solved by technology

[0003] In the actual cleaning process, the temperature of the lye in the alkali tank is an important factor affecting the cleaning of the recovery bottle. If the temperature is too low, it is not easy to clean the recovery bottle, and if the temperature is too high, it will easily cause waste of resources; for the filter device, due to The pressure it bears is relatively large, and the top cover is easy to be pushed open, resulting in the spraying of lye, which poses a very large safety hazard. The force will decrease rapidly, which is not conducive to the effective operation of the next process

[0004] The bottle washing machines in the prior art cannot actively shut down when faced with the above problems, which may easily lead to safety accidents and affect the working efficiency of the bottle washing machine
