[Industrial applications]

 The present invention relates to a cleaning device, and its purpose is to provide a cleaning device having a simple and rational structure, which effectively uses water and heat sources that have been wasted in the past, and which is highly energy and resource efficient. is there.

[0002]

[Prior Art]

 The conventional cleaning device includes a pre-cleaning mechanism that first removes easily dislodged rough dust, sand, mud, etc., then a main cleaning mechanism that removes dirt adhering by adding detergent, and the detergent that adheres during the main cleaning. Also, each mechanism of the clean cleaning mechanism for washing away dirty water is provided in series, and the object to be cleaned is sequentially cleaned by the above mechanism. Each of the above mechanisms is provided with a cleaning liquid (water) tank, and the solution in the tank is controlled at 60 ° C to 80 ° C at which dirt is most likely to be removed.

[0003]

[Problems to be solved by the device]

 In the conventional cleaning device described above, the solution in each mechanism is replenished and distributed by an independent circulation path.For example, the water used in the clean cleaning mechanism is compared with the water used in the preliminary cleaning mechanism. Despite its low degree of pollution, it is released as it is because it is not suitable for reuse in the cleansing mechanism. Therefore, there are many wastes of water and heat energy. Further, the cleaned object is sent to the drying device for drying, but a large amount of water adheres to the cleaned object immediately after the clean cleaning, and it is dried as it is. When it is sent to the chamber, the moisture evaporates, so that the dryer requires extra heat energy. For this reason, the amount of water adhering to one box-shaped container (about 650 mm x about 400 mm x about 150 mm) for transporting bread and noodles is about 150 g, and a washing machine that treats 25 pieces per minute can irrigate the drum per hour. This is an amount equivalent to the main amount.

 An embodiment of the present invention will be described below with reference to the drawings. The cleaning apparatus of the embodiment continuously cleans a box-shaped plastic container (hereinafter referred to as a container) that mainly stores and carries bread, noodles, etc., and as shown in FIG. A pre-cleaning mechanism 2, a main cleaning mechanism 3, and a clean cleaning mechanism 4 are provided in this order from the upper side of the chain conveyor 1 that can be transported. Each cleaning mechanism is provided with solution tanks (hereinafter referred to as tanks) 2a, 3a, 4a below the conveyor 1, and cleaning solution jetting nozzles 2b, 3b, 4b around the conveyor 1, which are tanks 2a, 3a. The cleaning liquid in 4a is sprayed from the ejection nozzles 2b, 3b, 4b to the container A on the conveyor 1 via the pumps 2c, 3c, 4c. A partition 5 is provided between each mechanism to ensure that droplets do not mix with each other. The jet nozzles 2b, 3b, 4b are arranged so that the upper and lower positions thereof do not coincide with each other in the vertical direction so that the jetted liquids do not interfere with each other, and the jet nozzles 2b, 3b, 4b is attached to supply pipes 2d, 3d, and 4d that are endlessly arranged around the conveyor 1 from the pumps 2c, 3c, and 4c, and the ejection pressure of each nozzle is more uniform than that of conventional feed pipes.

In the cleaning apparatus of this embodiment, in addition to the above-described cleaning mechanisms, a drainer mechanism 6 is provided on the lower side of the conveyor 1, that is, in succession to the clean cleaning mechanism 4. The water draining mechanism 6 blows warmed air vigorously against the container A on the conveyor 1 by the blower 6a to blow off the adhered water. Below the water draining mechanism 6 and the cleansing and cleaning mechanism 4, there are provided a water receiver 7a which covers the entire lower parts of both mechanisms and is tapered so that the received water gathers in one place, and a trough-shaped water reservoir 7b. The collecting mechanism 7 configured as described above is provided so that the used water in the cleansing mechanism 4 and the falling water in the draining mechanism 6 can be collected together. Further, a water supply pipe 8a connected to the tank 2a of the preliminary cleaning mechanism 2 is connected to the water reservoir 7a of the recovery mechanism 7 so that the recovered water can be sequentially replenished to the tank 2a via a pump 8b.

[Industrial applications]

 The present invention relates to a cleaning device, in particular, a cleaning device for a box-shaped container, which aims to effectively use water and heat sources which have conventionally been wasted, with a simple and rational structure. It is intended to provide a cleaning device having a high cleaning effect while enhancing resource and energy saving effects.

[0002]

[Prior Art]

 In the conventional cleaning equipment, first, preliminary cleaning is performed to wash away easily dislodged rough dust, sand, mud, etc. Rinse out in order. Each cleaning mechanism is provided with a separate tank of cleaning water (liquid), and the cleaning water in the tank is controlled at 60 ° C to 80 ° C where dirt is most likely to be removed. In this way, the cleaning water in each mechanism is supplied and discharged through independent circulation paths, so for example, the water used in this cleaning mechanism is more polluted than the water used in the preliminary cleaning mechanism. Although the degree of cleaning is low, it is not suitable for reuse in the main cleaning mechanism and is drained as it is, resulting in much waste of cleaning water. Therefore, in order to eliminate these drawbacks, the overflow water of the main cleaning mechanism is used in the pre-cleaning mechanism as in the "dishwasher" described in Japanese Utility Model Publication No. Sho 49-132668 to effectively use the water. Attempts have been proposed to achieve

[0003]

[Problems to be solved by the device]

 However, the above-mentioned conventional device only uses the overflow water of the main cleaning mechanism on the immediate upstream side of the main cleaning mechanism. This means that the main cleaning mechanism is expanded to the pre-cleaning mechanism side and one cleaning mechanism is used. It is not much different from performing one cleaning process. It is also important to note that there is a lack of consideration for a consistent cleaning system that includes the rinsing process and drying process, and consideration for enhancing the cleaning effect. That is, the object to be cleaned after the cleaning process is finally sent to the drying device to be dried, but immediately after the cleaning, a large amount of water adheres to the object to be cleaned and remains as it is. When it is sent to a drying device, these water vapors evaporate, which requires extra heat energy. By the way, the amount of moisture attached to each box-shaped container (about 650 mm × about 400 mm × about 150 mm) for transporting bread and noodles is about 150 g, and it takes about 1 hour for a cleaning device that can process 25 pieces per minute. What a water equivalent to one drum irrigation is attached to. From the viewpoint of constructing a consistent cleaning system from cleaning to pre-drying to drying, the conventional cleaning device is poor in resource saving and energy saving effects. Moreover, the cleaning water ejected from the upper and lower nozzles interferes with each other, resulting in unevenness in the ejection output, resulting in poor cleaning efficiency. Therefore, improvement of the arrangement of nozzles for spraying washing water on the container is also desired.

[0004]

[Means for Solving the Problems]

 The present invention consistently performs from cleaning to predrying, and in the series of steps, enhances the cleaning efficiency, reuses the used cleaning water that was previously wasted by the cleaning mechanism, and heats the dryer. This product was developed to reduce energy consumption and also to spray cleaning water efficiently. Its structure is pre-cleaning, main cleaning, clean cleaning, and warm air spraying along the transport path. A plurality of endless cleaning water supply pipes each having an ejection nozzle inside and connected to each other are arranged in series in the cleaning mechanism, and the cleaning water supply pipes pass through the conveyance path inside and are adjacent to each other. The supply pipes are arranged in a slanting manner so that the standing inclination direction with respect to the conveyance surface is the reverse direction to the conveyance direction, and the inclination direction is opposite to the conveyance direction.Furthermore, at the bottom of the cleaning mechanism and the draining mechanism, Both mechanisms It provided with a recovery mechanism for recovering Oite no longer needed water, Ru near providing the feeder for replenishing the water recovered by the recovery mechanism of that the prewashing apparatus.

[0005]

[Action]

 According to the present invention, a plurality of endless cleaning water supply pipes each having an ejection nozzle inside and connected to each other are arranged so as to pass through the conveyance path to the inside, and each adjacent supply pipe is connected. Since the rising inclination direction of the pipe with respect to the conveying surface is inclined so as to be the opposite direction to the conveying direction, the cleaning water ejected from the upper and lower ejection nozzles does not interfere with each other, and As the cleaning water is sprayed to every corner, the used cleaning water collected by the relatively clean cleaning mechanism and the draining mechanism is replenished to the precleaning mechanism that is heavily contaminated. It is more economical than supplying water. Moreover, since the temperature of the recovered wash water to be replenished is much higher than that of ordinary tap water, heating in the preliminary wash mechanism is small and it is the best energy saving measure.
