DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a used barbecue plate or net which is used for collecting a used plate such as used meat plate or barbecue from a barbecue store and washing it. And a dry regeneration treatment method.

[0002]

2. Description of the Related Art Conventionally, in a barbecue store, roast, ribs, mino, tongue, and other desired meats or vegetables are placed on a roasted meat plate or a net made of various shapes and cast and baked. However, small pieces of meat, oil, sauce, or small pieces of vegetables adhere to the surface of the used grilled meat plate or net. Therefore, a barbecue shop prepares a large number of grilled meat plates or nets, and replaces the plate or net for each customer anew. Since it is extremely difficult to wash the inside of the plate or plate, the plate or ash that has been washed and finished in a washing factory and delivered to a specialized washing company is reused.

[0003] When washing such a used plate of used yakiniku or nets, it is necessary to use water,
The mainstream is oil removal with detergents and the like.For example, a rotating drum system in which chips, water, and detergent are carried into a washing drum and washed by a rotating drum, a high-pressure water jet system in which cleaning is performed only by jetting ultra-high-pressure water, and the like. A shot blast method of washing with a hot water detergent and a shot agent, or a hand washing method, and the like have been implemented. Among these conventional methods, a so-called wet cleaning method using a strong alkaline detergent is mainly used. Because of this, the turbidity of oil and carbides in the wastewater is pH 11.1.
7, SS 2500mg / l, COD 1200/1, BOD 1500mg / l,
The results of analysis of animal and vegetable oils / 1000 mg / l of raw water for washing indicate that the washing wastewater greatly exceeds the wastewater standards based on the Water Pollution Law, and as a result, a designated facility (a surface treatment facility using acid or alkali) ), A notification was required in advance, and the installation of a wastewater treatment plant was inevitably required as the exclusion facility, and the treatment costs resulting from the installation of these facilities were extremely oppressive in terms of profitability. For this reason, there is a defect that a large amount of untreated wastewater is discharged without exceeding the regulation of the Water Pollution Law.

Further, in the conventional cleaning method, since the cleaning liquid is strongly alkaline, there is a risk of burns when the splash comes into contact with the skin. After cleaning the plate, the water is wiped off by hand for each sheet. Poor workability, occupational hearing loss due to intense noise from drum-type washing machine, easy use of water in the entire workplace, work floor wet and slippery, hot and humid As a result, the working environment deteriorates, and furthermore, the barbecue plate or net is heavy, so that the load on the operator's waist and shoulders during transporting and washing is extremely large.

[0005]

However, in the method of dry-recycling used barbecue plates or nets developed by the present invention in the present invention, in view of the various kinds of conventional defects described above, intensive studies have been made. Developed as a result, exceeding the high-concentration drainage standard by the wet cleaning method using water and detergent, eliminating defects that had been washed out and discharged with almost no treatment, and acid and alkalinity. Eliminates the need for a special facility to use the cleaning solution, eliminates the danger of burns due to the scattering of the strong alkaline cleaning solution, the extreme noise that comes from the cleaning machine, and the high temperature and humidity caused by the large amount of water used. In addition to preventing the floor from becoming slippery, it also has excellent workability for transporting grilled meat plates or nets, can significantly reduce the burden on the waist and shoulders of workers, and can significantly reduce fatigue. Contribute to environmental improvement , Sufficiently made clear quality control, may also contribute to offload pollution control, and to provide a dry regeneration treatment of used roast plate or amino and the like.

[0006] Further, since the washing process of the used grilled meat plate or ash is performed by a dry washing method,
Wastewater treatment is not required, it is an environmentally friendly treatment method, and because it is a dry cleaning method, water and detergent and wastewater treatment costs can be saved, contributing to the creation of a recycling-oriented society as a resource-saving industry, and its ripple effect. It is an object of the present invention to provide a method of dry-recycling a plate or plate for spent meat which becomes enormous.

[0007]

SUMMARY OF THE INVENTION In order to effectively achieve the above-mentioned object, the present invention relates to a method for regenerating a used BBQ plate or a reticle or the like using a used BBQ plate. An object to be treated, such as a mystery, is guided to a heating chamber, a heating and burning treatment step for accelerating ashing of oil and carbide, a cooling treatment step for further guiding this to an air cooling chamber, and an incineration attached to the treatment object It features a dry regeneration treatment method for a used grilled meat plate or net, which consists of a shot blasting process for removing oil and carbides, and an oiling process for the object to be processed. The heat treatment process of guiding the material to be treated to the heating chamber to promote the incineration of oil and carbides, the cooling process of guiding the material to the air cooling chamber, and the incineration of the material to be treated It is characterized by a dry blast treatment method for used grilled meat plates or nets consisting of a shot blast treatment step of removing carbides, an air blast treatment step of removing finer impurities, and an oiling treatment step of an object to be treated. Is what it is.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION In a dry regeneration method for a used meat plate or a net of the present invention, a dirty used meat plate or a net is collected from a meat store.
A large number of recovered plates or objects to be processed, such as nets, are sequentially removed by heating and burning to remove oil and water attached to the objects to be processed, to promote incineration of carbides, and to be further processed by shot blasting. It removes carbides that adhere and then keeps the object to be treated reusable by an oiling process.However, before the oiling process, a buffing process can be performed to add gloss to the product itself. Of course. For more details, used round or square, various kinds of processing objects such as various kinds of grilled meat plates or nets,
The jig 1 is appropriately hung on a hanging jig 1, hung on a work hanger, and then guided to a heating chamber 2.
Cooling for passing the heat-treated object to the air-cooling chamber 3 to cool the object to a certain temperature by passing through a heating and burning treatment step for accelerating the incineration of oil and carbide attached to the object to be treated After passing through the treatment step, the oil passes through a shot blast treatment step in which the ashed oil and carbide attached to the object to be treated are removed by the shot blasting device 4, and is subjected to an oiling treatment by spraying oil by a conventional method. It is what is done.

According to a second aspect of the present invention, there is provided a method for dry-recycling a used grilled meat plate or a net, which removes finer impurities adhering to an object between the shot blasting step and the oiling step. In order to ensure the removal, a dry regeneration method of a used grilled meat plate or a net, etc., with an air blast treatment device 5 interposed, and a dry cleaning method that does not require wastewater treatment is used, and a wet cleaning method is used. As described above, there is no pollution problem such as drainage of the washing waste liquid exceeding the high-concentration wastewater standard, and this is an excellent environmentally friendly treatment method.

[0010]

Next, an embodiment of the present invention relating to a dry regeneration method for a used plate for grilled meat or a net according to the present invention will be described in detail.

On a work hanger of an appropriate shape, a used plate for meat processing or a plate to be processed, such as a net, collected from a yakiniku store is hanged with 56 plates / jig and 112 nets / jig. In this case, as the material of the hanging jig 1, a material that can withstand the heating and burning treatment and the shot blasting treatment is selected.

A jig 1 holding such a large number of workpieces
Is guided to a heating chamber 2 for sequentially performing heating and burning treatments by two jigs / batch while being hung on a work hanger. Oils and carbides adhering to an object to be processed in the heating chamber 2 are removed by a hot air burner. Heating and burning with a hot blast stove promotes incineration. In the heating chamber, the temperature is in the range of 400 to 500 ° C, preferably 4 ° C.
A heat treatment is carried out for about 10 to 12 minutes while maintaining the temperature at 30 to 480 ° C., and the oil and carbides are forcibly baked to promote incineration, whereby a shot blasting treatment of the secondary treatment becomes possible. That is, if oil is attached to the object to be processed or if moisture exists, the shot blasting cannot be performed. When the above-mentioned heating temperature is set to 500 ° C. or higher, an oxidation phenomenon easily appears on the iron plate, and when the heating temperature is set to 400 ° C. or lower, a residue remains and it takes time to incinerate it. .

Next, the object to be processed, which is held by the jig 1 and in which the oil and carbides have been ashed, is guided to the air-cooling chamber 3 while being hung on a work hanger. Cooling treatment is performed down to ℃.

The object to be processed after the cooling process is guided to a shot blasting device 4 in order to remove ashed oils and carbides adhering thereto.
The jig 1 is removed from the hanger rail with a table lifter, and the jig 1 is replaced with a hoist crane for shot blasting as it is. Such a shot blasting device 4
Is suitable for removing relatively large ash adhering to the object to be processed, and the shot media is made of SUS, 0.5 mm, so that iron powder that causes rust from the media itself is not generated.
A ball is used for selection. The ash removed by the shot blast device 4 is collected by the dust collector 6.

As described above, the processed object from which the oil and the carbide adhered almost completely to the processed object have been removed is polished by a buffing finish by a conventional method to give gloss, and The oil is sprayed and subjected to an oiling process to form a reusable barbecue plate or net, which is delivered to the collected barbecue store.

According to the processing method of the second aspect, an air blast processing device 5 is interposed between the shot blast processing step and the oiling processing step. Fine impurities can be reliably removed. In this air blast device 5,
Fine glass bead particles in the order of microns are blown together with air to process finer impurities that cannot be eliminated by the shot blasting device 4. After the oil and carbides adhering to the object to be treated are ashed, they are collected by the dust collector 6 and all the solid waste can be subjected to industrial waste treatment. .

[0017]

According to the present invention, in place of the wet cleaning method using a large amount of water and a strongly alkaline cleaning liquid, a dry cleaning method using a dry cleaning method that does not use a large amount of water and a strongly alkaline cleaning liquid or a method for dry regeneration of a used meat plate or a net is used. As a result, environmental destruction due to the conventional method, in which washing wastewater that greatly exceeds the high-concentration wastewater standards flows down almost untreated, is corrected, and there is no need for specific facilities to use acids or alkaline cleaning solutions. Prevents burns caused by washing liquid splashing, extreme noise generated by the washing machine, slipperiness of the floor surface caused by heavy use of water, reduces physical fatigue of workers, and reduces heavy muscle work. There is an advantage that the working environment can be remarkably improved.

Furthermore, a wastewater treatment is unnecessary, and a treatment method which can clear environmental protection type pollution control can be achieved, so that water supply, detergent and wastewater treatment costs can be saved, and at the same time, it can contribute to the prevention of urban water pollution, and The oils and carbides adhering to the processed material are ashed and polished as they pass through each process, and then collected by a dust collector, where all solid waste can be treated as industrial waste, and factory wastewater can be treated. And the quality of the object to be treated is always constant.
