Energy saving system for bottle washing machine

Abstract

The invention discloses an energy saving system for a bottle washing machine. The energy saving system comprises a pre-sprinkling tank, a temperature increase pipeline, a heat exchanger and a temperature decrease pipeline. The temperature increase pipeline comprises a temperature increase water outflow pipeline and a temperature increase water inflow pipeline. The water inflow end of the temperature increase water inflow pipeline is connected with a water outlet of the pre-sprinkling tank. The water outflow end of the temperature increase water inflow pipeline is connected with a water inlet of a first heat exchange medium pipeline on the heat exchanger. The temperature increase water outflow pipeline is connected to the portion between a water outlet of the first heat exchange medium pipeline and a sprinkling head of the pre-sprinkling tank. The temperature increase pipeline is provided with a pre-sprinkling pump. The temperature decrease pipeline comprises a temperature decrease water outflow pipeline and a temperature decrease water inflow pipeline. The water inflow end of the temperature decrease water inflow pipeline is connected with a water outlet of an alkali tank on the lowest stream of the bottle washing machine. The water outflow end of the temperature decrease water inflow pipeline is connected with a water inlet of a second heat exchange medium pipeline on the heat exchanger. The temperature decrease water outflow pipeline is connected to the portion between a water outlet of the second heat exchange medium pipeline and a water inlet of the alkali tank of the lowest stream. The temperature decrease pipeline is provided with a loop sprinkling pump. By the adoption of the energy saving system, the temperature of discharged washed bottles is guaranteed and heat energy is effectively used.

Description

technical field [0001] The invention relates to the field of glass bottle washing machines, in particular to an energy-saving system for a bottle washing machine. Background technique [0002] The existing glass bottle washing machine includes several alkali tanks. During the whole cleaning process, the glass bottles go through the pre-spraying, the first alkali tank, the second alkali tank, the third alkali tank, and finally the most downstream alkali tank. , the temperature of the glass bottle drops rapidly in the early pre-spraying and the first alkali tank, and the temperature of the glass bottle in the downstream alkali tank will gradually rise, getting closer to the temperature of the previous alkali tank, resulting in the rear As the temperature rises, the structure of the existing bottle washing machine does not have an energy-saving system, which leads to two problems: first, the temperature of the most downstream alkali tank is relatively high, which will easily le...
