Description

  The present invention relates to an aerosol can chlorofluorocarbon transfer and filling device, and more particularly to an aerosol can chlorofluorocarbon transfer and filling device capable of efficiently recovering chlorofluorocarbon existing in an aerosol can.

  Conventionally, chlorofluorocarbons recovered from air conditioners and the like are detoxified by destroying chlorofluorocarbons using chlorofluorocarbon destruction devices. As a method for destroying chlorofluorocarbons, a technique is known in which chlorofluorocarbon is accumulated in a large-capacity tank (for example, a container of 100 kg or more), chemically detoxified and destroyed for efficient processing (for example, , See Patent Document 1).

JP-A-10-238909 (7th page, 8th page, FIG. 1)

As shown in Patent Document 1, chlorofluorocarbon is made harmless by a destruction device, but it is necessary to supply the device with a large-capacity container or the like in order to perform efficient processing.
In general, many aerosol cans manufactured for the purpose of cleaning and washing electronic device parts such as personal computers are filled with chlorofluorocarbon, and these aerosol cans are no longer used from the viewpoint of protecting the ozone layer. Therefore, it is necessary to dispose of aerosol cans (stocks owned by companies, etc.) that exist in the distribution process. However, since aerosol cans contain only about several hundred grams of chlorofluorocarbon, supply them to the destruction device. There is a problem that a large container has to be refilled before it is done.
Further, in order to perform efficient transfer and filling, it is necessary to transfer and fill a large number of aerosol cans at the same time.

Generally, chlorofluorocarbon in an aerosol can is in a state where liquid and gas are saturated. In order to efficiently extract chlorofluorocarbon, a process of extracting the liquid with a chlorofluorocarbon recovery machine, recovering the gas when the liquid is exhausted, and finally recovering until the inside of the can is evacuated can be considered.
However, recovery of gasified chlorofluorocarbons has poor processing efficiency, and in order to improve the processing capacity, it is necessary to extract almost all of the chlorofluorocarbon with liquid.
Since the CFC recovery machine generally has a positive displacement transfer structure, the liquid can move more mass if the volume is the same. Furthermore, when gas is extracted in a state where there is a liquid, there is a problem that the liquid is vaporized inside the can and the can surface is frozen by the heat of vaporization.

As shown in FIG. 2A, the pressing means 10 for pressing the aerosol can K is formed with a pressing portion 11 as a portion for pressing the aerosol can K. The pressing portion 11 is connected to the rod 12. The rod 12 is configured to be slidable in the cylinder 13. The rod 12 and the cylinder 13 are configured such that the rod 12 can be locked at a predetermined position in the cylinder 13 by the position adjusting means. Thus, the length of the rod 12 and the length of the cylinder 13 are configured so that the stroke can be expanded and contracted.

  The position adjusting means for the rod 12 and the cylinder 13 can be engaged and disengaged with screws, scissors and other known means. FIG. 2B shows an example in which the pressing means 10 is adjusted by the position adjusting means and the distance between the CFC discharging means 20 and the pressing portion 11 is adjusted with respect to the lengths of the rod 12 and the cylinder 13 as described above. It is. Thereby, it is possible to sufficiently press even an aerosol can having a low height. The position adjusting means may be adjusted by screwing the rod 12 into the cylinder 13.

  The rod 12 is connected to a lever 15 connected through a link mechanism 14. The lever 15 is movable in the arrow direction X by the support shaft 16, and by moving the lever 15, the rod 12 moves in the arrow direction Y, and the pressing portion 11 moves to the Freon discharge means 20 side. It has become.

  As shown in FIG. 3, the chlorofluorocarbon discharging means 20 of this example is connected to the nozzle N of the aerosol can K inverted, and is inclined to seal with the nozzle N when the nozzle N is connected. It is comprised by the taper surface piping joint provided with the sealed surface 21 which was made. In addition, since the nozzle diameter of the nozzle N is substantially the same (about φ3.5 to 4.0) regardless of the manufacturer, the same CFC discharge means 20 (tapered surface pipe joint) can be used.

Further, the chlorofluorocarbon discharging means 20 is connected to the connecting pipe 50, and the connecting pipe 50 is connected to the chlorofluorocarbon collecting means 30. Further, the chlorofluorocarbon recovery means 30 is connected to the large-capacity storage container 40 through the pipe body 51.
A well-known fluorocarbon recovery machine as the fluorocarbon recovery means 30 of this example can be used. The large-capacity storage container 40 also uses a 100 kg class tank, and a known container can be used. Reference numeral 60 denotes a valve such as a check valve.

  Thus, the aerosol can chlorofluorocarbon transfer and filling device S having the above-described configuration is configured such that the aerosol can K is inverted, the nozzle N and the chlorofluorocarbon discharging means 20 are connected, the lever 15 of the pressing means 10 is rotated and pressed. The aerosol can K is pushed by the part 11. In this way, a plurality of aerosol cans K are pushed sequentially or simultaneously.

  That is, this embodiment utilizes the fact that the body of the aerosol can K has a cylindrical shape. As the Freon discharge means 20, a piercing nozzle that is used during the operation of collecting Freon from the equipment using Freon is used. The CFC liquid F and / or CFC gas GF is extracted by making a hole in the lower part of the body of K.

  The aerosol can Freon transfer and filling device S having the above-described configuration is installed with the nozzle N facing up in a normal state. Then, the fluorocarbon discharging means 20 is positioned at the lower part of the aerosol can K, the lever 15 of the pressing means 10 is rotated, and the aerosol can K is pushed by the pressing portion 11. In this way, a number of aerosol cans K are pushed sequentially or simultaneously. In this way, the Freon discharge means 20 (piercing nozzle) pierces the side surface of the aerosol can K and is connected to the aerosol can K. As a result, the chlorofluorocarbon liquid F and / or the chlorofluorocarbon gas GF in the aerosol can K is stored in the large-capacity storage container 40 via the valve 60, the connecting pipe 50, the chlorofluorocarbon recovery means 30, and the pipe body 51.
