Spray needle device of bottle washing machine with balanced water jet capacity

Abstract

The invention relates to a spray needle device of a bottle washing machine with balanced water jet capacity. The spray needle device comprises a tabular spray needle frame which laterally extends and a plurality of spray needles which are vertically arranged on the spray needle frame, wherein the spray needle frame comprises a water flow channel which laterally extends and a plurality of round grooves which are vertically formed respectively and have one ends being communicated with the water flow channel, each spray needle comprises a hollow needle bar and a round base which is positioned on the tail end of the needle bar, and bases are respectively arranged in the grooves; and the spray needle device is characterized in that in the grooves, sealing gaskets and throttling orifices are also sequentially arranged on the bottom ends of the bases which correspond to the spray needles, a first through hole with a sectorial cross section is formed in each throttling orifice, and a second through hole with the sectorial cross section is formed in each base. The spray needle device can adjust the peripheral relative positions of the bases and the throttling orifices through rotating the spray needles, so that the spray water pressure is changed, the water jet capacities of all the spray needles are maintained balanced, and on the basis of ensuring the cleaning effects of all the spray needles, a water-saving effect of a certain degree can also be realized.

Description

technical field [0001] The invention relates to a food machine part, in particular to a needle spray device of a bottle washing machine. Background technique [0002] In the field of production and processing of bottled liquid foods such as fruit juices and beverages, in order to ensure that the bottle-shaped containers holding the food are clean and hygienic, a special cleaning equipment such as a bottle washing machine is often used. For example for cleaning glass and plastic bottles. The most important part of the bottle washing machine is the spray needle device, which is fixedly installed under the pipeline that conveys the bottles to be washed. When working, the spray needle extends into the upper cavity corresponding to the bottle to be washed to spray water for cleaning. The spraying needle device includes a horizontally extending flat spraying needle frame and a plurality of longitudinally extending spraying needles arranged on the spraying needle frame. Since each...

Problems solved by technology

The spraying needle device includes a horizontally extending flat spraying needle frame and a plurality of longitudinally extending spraying needles arranged on the spraying needle frame. Since each spraying needle is supplied with water through a horizontal water flow channel with a single water inlet in the spraying needle frame, The spray needles at different positions from the water inlet will obtain different water pressures, resulting in different water spray volumes, and there is a problem that some spray needles are not clean when washing bottles
