Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings:

[0019] figure 1 It is a front view of the present invention. The water nozzle 8 and the air nozzle 9 are welded on the bracket 10 , and the upper ends are welded on both sides of the valve seat 2 .

[0020] figure 2 It is a sectional view of the valve seat part of the present invention. The valve seat 2 is equipped with a nozzle 1, the two ends of the valve seat 2 are installed with a left head 3 and a right head 11, the sealing heads at both ends and the valve seat 2 are sealed with a sealing ring 4, and the valve seat 2 has a valve hole inside the valve hole. A valve core 6 is installed inside, and the outer edges of the two sides of the valve core are respectively covered with a first sealing ring 5 and a second sealing ring 7. The valve core slides in the valve hole under the influence of water pressure or air pressure to realize automatic water and gas switch...

Abstract

The invention provides a device capable of automatically switching between water and air and for cleaning liquid packaging containers. The cleaning device comprises a valve seat, a nozzle is arranged on the valve seat, a water spraying pipe and an air spraying pipe are connected to two sides of the valve seat respectively, a valve port is formed inside the valve seat, a valve spool is mounted in the valve port, a first sealing ring and a second sealing ring are sleeved at outer edges of two sides of the valve spool respectively, and the valve spool slides in the valve port to realize automatic water and air switching under the influence of water pressure or air pressure. The device has the advantages that functions of washing and draining are achieved simultaneously, the problem about residual water draining after containers are cleaned with water is solved, production process is simplified, cleaning time is saved, and cost is lowered.

Description

technical field [0001] The invention relates to a filling production line, in particular to a water and gas automatic switching cleaning device for cleaning liquid packaging containers. Background technique [0002] There are various types of liquid packaging containers, which must be cleaned before packaging. There are two forms of cleaning of packaging containers: [0003] 1. For some simple bottle types, the traditional inverted filter drying can also achieve the effect, but the equipment needs to have enough drying time. [0004] 2. For some special bottle shapes, the water droplets remaining inside the container cannot be removed by simply inverting and filtering, and they must be washed with water and then purged with sterile air. A large amount of residual water remains in the nozzle of the traditional sterile air purging device after water washing, which leads to a long time for the sterile air purging process, the cleaning equipment needs to be very large, and ...
