Description

  The present invention relates to a filtration device for filtering a liquid and a cleaning facility in which the filtration device is incorporated.

A washing device (bottle washing machine) for washing beer bottles is used for washing bottles collected from the market or newly introduced bottles. There is a possibility that various foreign substances such as paper pieces, stickers, chopsticks and toothpicks are mixed in or attached to the bottles collected from the market. In the bottle washer, a relatively clean cleaning liquid (for example, the cleaning liquid used in the final cleaning process) among the cleaning liquids used for cleaning the bottle may be filtered and used again for cleaning the bottle. In addition, the cleaning liquid discharged outside the factory after being used in the washing machine can also be discharged after being filtered.
JP 2001-232127 A

  In such filtration, the presence of various foreign matters such as paper pieces, stickers, chopsticks, toothpicks and the like as described above becomes a problem. If the filtration device becomes clogged and loses the filtration function, a situation may arise in which the bottle-washing machine must be stopped, resulting in a significant reduction in throughput.

  Therefore, it is effective to provide the filtration device with a function (automatic purification function) for purifying the filter (filter media). Here, for applications where foreign matters such as paper pieces, stickers, chopsticks, toothpicks and the like are randomly sent to the filter, a configuration in which the automatic purification function is operated periodically or intermittently may not be suitable. In other words, in applications where foreign matter is randomly sent to the filter, when a large amount of foreign matter is instantaneously sent to the filter, the automatic cleaning of the filter is delayed, and the apparatus such as the washing machine can be stopped.

  The present invention has been made on the basis of recognition of the problems as described above. For example, a filtration device having a purification function that can function effectively even in applications where foreign matter can be sent randomly to a filter, and incorporating the same The purpose is to provide the cleaning equipment.

  ADVANTAGE OF THE INVENTION According to this invention, the filtration apparatus provided with the purification | cleaning function which can function effectively also in the use which a foreign material can be sent to a filter at random, for example, and the washing | cleaning equipment incorporating it can be provided.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a diagram schematically showing a configuration of a cleaning facility according to a preferred embodiment of the present invention. The cleaning equipment 1000 according to a preferred embodiment of the present invention is configured to clean a container (an example of an article) 1 such as a beer bottle, and is used in the cleaning device 200 that cleans the container 1 with a cleaning liquid, and the cleaning device 200. And a filtering device 100 that filters all or part of the cleaning liquid for reuse or exhaust. Typically, only a relatively clean cleaning liquid (for example, the cleaning liquid used immediately before and after the final cleaning step) out of the total cleaning liquid used in the cleaning apparatus 200 is filtered by the filtering apparatus 100 and reused. Or it can be discharged out of the system. Other cleaning solutions can be processed through other filtration devices (eg, physical filtration devices, biological filtration devices) and reused as needed.

  The cleaning liquid used for cleaning in the first cleaning unit 210 and the second cleaning unit 220 is recovered by the recovery pan 230 and supplied to the filtration device 100. The first cleaning unit 210 is a cleaning unit arranged in front of the second cleaning unit 220 and cleans the container 1 using the cleaning liquid provided from the filtration device 100. The second cleaning unit 220 is disposed, for example, at the final stage of the cleaning process, and finally cleans (finishes cleaning) the container 1. The second cleaning unit 220 may typically be provided with fresh cleaning liquid (eg, tap water or water that has been processed). The first and second cleaning units 210 and 220 have, for example, a cleaning nozzle, and clean the container 1 by spraying a cleaning liquid from the cleaning nozzle toward the container 1.

  The filtration device 100 is a useful device by itself, and the annular filter 10 that moves around along a circulation path (a path in which the annular filter 10 is described in FIG. 1) that passes through the filtration region 12 and the purification region 14. It has. For example, the annular filter 10 is stretched over the lower pulley 16 and the upper pulley 18 and is driven by at least one of the pulleys 16 and 18 to move around.

The cleaning liquid recovered by the recovery pan 230 in the cleaning apparatus 200 is supplied to the supply unit 20 of the filtration apparatus 100 through the liquid feeding pipe 240, for example. The supply unit 20 is configured to supply the cleaning liquid discharged from the cleaning device 200 to the annular filter 10 in the filtration region 12. The supply unit 20 can typically be configured as a tank structure that provides a cleaning liquid to the upper surface of the annular filter 12. In the example shown in FIG. 1, a part of the annular filter also functions as a part of the tank structure. The foreign matter 3 in the cleaning liquid is captured by the portion moving on the upper side of the annular filter 12 in the filtration region 12. In the annular filter 12, the part moving on the upper side among the part moving on the upper side and the part moving on the lower side rises (in FIG. 1, rises to the upper left) (in FIG. 1, Driven by pulleys 16 and / or 18 counterclockwise.
Below the filtration region 12, a collection unit 30 that collects the cleaning liquid filtered by the annular filter 12 in the filtration region 12 is disposed. The collection unit 30 can typically be configured as a tank structure.

  In the purification region 14, a purification unit (injection nozzle) 40 is disposed inside the circular movement path of the annular filter 10 (between a part moving on the upper side and a part moving on the lower side), and the annular filter The annular filter 10 is purified by spraying a purification liquid toward the outside (preferably downward) of the filter 10. The foreign matter 3 removed from the annular filter 10 by the cleaning liquid is collected by the foreign matter collection unit 50 and discharged to the discharge unit 60.

The filtered cleaning liquid recovered by the recovery unit 30 is sent to the cleaning device 200 or another device by the pump 80 and reused. It is preferable that the filtered cleaning liquid recovered by the recovery unit 30 is further provided to the purification unit 40. Since the purification unit 40 is sufficient to perform the function of removing foreign substances from the annular filter 10, it is generally unnecessary to use fresh water or the like, and it is sufficient to use the cleaning liquid filtered by the filtration device 100. Can fulfill its function. Since it is preferable that the purification unit 40 is always driven during the operation of the filtration device 100, it can be said that the amount of the purification liquid required for this is relatively large. Therefore, it is not preferable to use fresh water such as tap water from the viewpoint of running cost.
A liquid level sensor 70 is disposed in the recovery unit 30, and the amount of filtered cleaning liquid in the recovery unit 30 is monitored thereby. When the amount of the cleaning liquid is insufficient, the cleaning liquid (for example, fresh water such as tap water) is supplied to the recovery unit 30 through the port 32.

As described above, by providing the annular filter 10, the part purified by the purification unit 40 can be always provided to the filtration region 12 as a part that functions as a filter (filter medium). Therefore, it is possible to always filter the cleaning liquid with a high processing capacity. Further, even when a large amount of foreign matter 3 is sent randomly (for example, suddenly) from the cleaning device 100, there is no problem that the filtering function is lost for a long time. In particular, containers collected from the market may contain or adhere to paper pieces, stickers, chopsticks, toothpicks, and various foreign objects that cannot be predicted. When such foreign substances are intensively fed from the cleaning device 200, the filtering function of the filter that can only purify the filter only on a regular basis significantly reduces the filtering function of the filter. The cleaning liquid may overflow from the apparatus, or the cleaning apparatus 200 must be stopped.
Further, by disposing the purification unit 40 inside the circular movement path of the annular filter 10 and injecting the purification liquid toward the outside of the annular filter 10, the foreign matter adhering to the annular filter 10 is effectively annular. The filter 10 can be detached. This is because most of the foreign matter 3 adheres to the outer surface of the annular filter 10. Further, by configuring the purification unit 40 so as to spray the purification liquid downward, the foreign material collection unit 50 for collecting the foreign material removed from the annular filter 10 can be simplified. As exemplarily shown in FIG. 1, the foreign substance recovery pan may simply be disposed below the purification unit 40.

It is a figure which shows typically the structure of the washing equipment of suitable embodiment of this invention.
