INDUSTRIAL APPLICATION FIELD The present invention relates to an air cleaning device for the inner surface of a container. 2. Description of the Related Art Conventionally, air cleaning devices for containers such as plastic bottles have been proposed, for example, structures shown in FIGS. 6 to 8. This conventional device includes a tip jet port 2 that spouts cleaning air in the direction of the central axis of the cleaning nozzle 1;
The nozzle 1 has a side jet port 3 that jets out cleaning air in a direction crossing the central axis of the nozzle 1, and the side jet port 3 is formed on the outer peripheral surface of the nozzle 1 as shown in the exploded view of FIG. with an aperture length of 120°,
Three slit-shaped nozzles 3 tilted at about 30°
It is composed of a. Problems to be Solved by the Invention However, the conventional air cleaning device described above cleans the inner surface of the container by the agitation effect of the air jetted out from the top and side nozzles, and the cleaning effect is not very good. Improvement was desired. Means for Solving the Problems The present invention has a cleaning nozzle that is inserted from the mouth of the container into the container, and has a jet port that spouts cleaning air in the direction of the center axis of the nozzle, and a jet port that spouts cleaning air in the direction of the center axis of the nozzle. In an air cleaning device having a side spout that spouts cleaning air in a transverse direction, the tip of the cleaning nozzle is open, and an air conduit is provided along the internal central axis between the cleaning nozzle and the nozzle. 〓
The tip of the air conduit projects outward from the tip of the cleaning nozzle to form a tip spout, and this outward protrusion between the tip of the nozzle and a lid plate having approximately the same shape as the outer diameter of the nozzle;
The present invention relates to an air cleaning device for the inner surface of a container, characterized in that it is fixedly installed to form an annular side air outlet. Embodiment An embodiment of the present invention will be described below based on the accompanying drawings. FIG. 1 is an enlarged vertical sectional view of the upper part of the cleaning nozzle 1 in the device of the present invention, and the nozzle tip 12 with an open tip is attached to the tip of the nozzle main body 11 with an open tip.
- Screwed together in an airtight manner with a ring. An air conduit 4 is inserted and fixed onto the central axis of the nozzle tip 12 via an air permeable support member 6 that connects the tip 12 and the conduit 4 so that a periphery 5 is formed around it. ing. In the figure, a disk-shaped member (see FIG. 2) having a large number of ventilation holes 6a arranged in parallel on concentric circles is used as the breathable support member 6.
A structure is shown in which the tubes are provided in two stages, upper and lower, with a cylindrical spacer 7 interposed therebetween. The structure and number of stages of the support member 6 are not particularly limited as long as they do not substantially impair the ventilation of the circumference 5. Note that a recessed step portion 121 is provided on the inner circumferential surface of the nozzle tip 12 for the purpose of preventing the support member 6 and eventually the air conduit 4 from slipping upward.
is formed. The tip 41 of the air conduit 4 projects outward from the tip of the nozzle tip, and its tip opening forms a tip nozzle 2 that spouts air in the direction of the central axis of the nozzle 1. This tip nozzle 2 is used to clean the bottom of the container a and the bottom part of the container body b adjacent thereto with air, and to pressurize the inside of the container a to prevent backflow of cleaning air. The opening area may be set as appropriate within a range that provides cleaning performance at the bottom of the container and a backflow prevention effect. On the outward protrusion 41 of the air conduit 4, a cover plate 8 having approximately the same shape as the outer diameter of the tip nozzle 12 forms an annular side spout 3 with the tip of the nozzle tip 12. It is fixedly installed so that The vertical width of the side spout 3 may be appropriately determined depending on the supply pressure of the cleaning air supplied into the cleaning nozzle 1. For example, the inner diameter of the cleaning nozzle 1 is 0.8 to 1.0 mmφ, and the cleaning air supply pressure is 4 to 1.0 mm. In the case of 5 kg/cm 2 (gauge pressure), 0.5 to 1.2 mm, especially around 0.8 mm is appropriate. Third
The figure shows the situation during the air cleaning operation of container a using the device of the present invention. During the cleaning operation, the cleaning nozzle 1 is inserted from the mouth c of the container a to near the bottom surface d, and then cleaning air is supplied from the base end of the nozzle 1 under a predetermined supply pressure as usual. A part of the cleaning air supplied to the cleaning nozzle 1 is ejected from the tip nozzle 2, collides with the central part of the bottom surface d of the container, and is diffused around the container to clean the bottom surface d and the inner surface of the body part b near the bottom surface. Pressurize the inside of container a. On the other hand, the remaining part of the cleaning air is ejected laterally from the side outlet 3 on the outer circumferential surface of the tip of the cleaning nozzle 1. Since this jet nozzle 3 is composed of an annular opening continuous in the horizontal direction, the cleaning air jetted from this becomes a thin film disc shape and collides with the inner surface of the body part b of the container a, and Due to the action of pressurization, the direction changes downward and flows down in a thin film form along the inner surface of the body b, and during this flowing down, the fine adhering components adhering to the inner surface of the body b are peeled off and the container a is discharged outside. The state of the flow of cleaning air at this time is schematically shown in FIG. Then, the air blow from cleaning nozzle 1 is
At the starting point A shown in the figure, the air blowing is performed for about 1 second, and then the nozzle 1 is turned 5 times while continuing air blowing.
The cleaning of the container a is completed by pulling it out to the loose construction end point B, taking about a second. Comparing the cleaning operation according to the present invention with the conventional apparatus shown in Fig. 6, it is found that in the conventional stirring method,
While the air blower is operated almost reciprocally from the lower end to the upper end to the lower end, the present invention only requires a one-way operation from the upper end to the lower end, thereby shortening the cleaning time and reducing the amount of cleaning air consumed. Furthermore, in the present invention, the cleaning air that flows down in a thin film along the inner surface of the container body b is configured to peel off fine deposits and discharge them, so that the so-called sweeping effect is achieved. A high degree of cleaning effect can be obtained regardless of one-way operation. The results of a comparative test on the cleaning effects of the device of the present invention and the conventional device shown in FIG. 6 are shown below. [1] Type of cleaning device Invented product: As shown in Fig. 3 However, the vertical width of the side nozzle 3 is 0.8 mm Conventional product: As shown in Fig. 6 However, the vertical width of the side nozzle 3 is 0.5 mm, and the angle
30° [2] Test equipment As shown in Figure 5. However, in the figure, 1 is a cleaning nozzle, e is an air ring, f is an air supply pipe, g is an air supply source, and a is a plastic bottle. [3] Test conditions (glass bead blowing test) ) 1 500 glass beads (diameter 100μ) shown in the table below
Put it inside the ml plastic bottle. 2 Insert the nozzle almost to the bottom of the bottle and blow air at a pressure of 4 kg/cm 2 for about 1 second. 3 Next, air blow (4Kg/
cm 2 ) and slowly pull out the nozzle. 4 Fill the air-washed bottle with pure water, rinse the inside, strain the pure water through a filter, and count the number of beads remaining on the filter. [4] Test results (10 times average value)
