Description

The present invention relates to a disinfectant injection device for a garbage collection vehicle that suppresses the emission of influenza virus and other viruses caused by collected garbage, or germs that cause food poisoning.

In Japan, general waste including kitchen waste and non-burnable garbage are divided into two categories, and recycled waste is collected under the name of recycling.
In Japan, which relies on incineration and landfill for most of the waste generated from homes and business establishments at a dedicated treatment plant, a garbage collection vehicle (packer vehicle) is indispensable. In a general garbage collection vehicle, a luggage box is mounted on a vehicle body frame, a garbage inlet is formed at the rear of the luggage box, and the garbage collection port faces the inlet of the luggage box to scrape in the dust. A device and a pushing device for pushing the dust into the packing box are provided. From the dust thrown in from the inlet, the dust bag is torn or the knot is loosened by the scraping device or the pushing device, and sewage containing fine dust flows out. A normal garbage collection vehicle is equipped with a tank for receiving sewage at the bottom of the packing box, and the sewage flows into the tank through the drain hole provided at the bottom of the inlet, that is, the top of the tank, so that it does not flow out. ing.

However, the sewage adhering to the inner surface of the packing box and the garbage bag has a problem of emitting a foul odor of garbage around the passage route of the garbage collection vehicle, especially when the garbage is thrown in. In addition, the foul odor of sewage is also emitted from the drain hole of the tank. Especially when the temperature is high, a large amount of garbage is compressed and stored in the garbage collection vehicle, and a considerable amount of foul odor is scattered around the treatment plant and the passage route of the garbage collection vehicle. This is not only unpleasant for the local residents, but also unfavorable for the health and hygiene of garbage collectors.

Collecting incombustible waste includes blankets and futons, and loading and collecting while crushing old tons and bicycles may cause dust droplets and sparks, so work at the vehicle inlet. For the purpose of protecting the respiratory system of the recovery worker and for maintaining the safety against fire, it is desired to suppress the droplets by the moisture of the spray system as in the present invention.
By the way, for sterilization of garbage treatment plants, methods that utilize strong reactions such as combustion method and ozone oxidation method are adopted, but it was difficult to attach such a large device to a garbage collection vehicle. .. It has also been found that most of the malodor of garbage can be significantly suppressed by suppressing putrefaction, that is, the growth of microorganisms. Therefore, hypochlorous acid and stabilized chlorine dioxide, which are inexpensive and have strong bactericidal activity, have been used until now, but due to recent environmental problems, especially the problem of dioxin generation during garbage incineration, these are chlorine that constitutes dioxin. Since it is a source, it is required to refrain from using it.
In view of the above problems, the present invention provides a dust collecting vehicle in which the emission of malodor is suppressed by a simple device and without using a dioxin generation source, and not only sterilization and dust prevention measures but also measures are provided. , It is an efficient device with the purpose of preventing ignition.

That is, in the disinfectant spraying device of the garbage collection vehicle of the present invention, a packing box is mounted on the vehicle body frame, a dust inlet is formed at the rear of the packing box, and the dust thrown into the dust inlet is filled with dust. At least one of a scraping device or a pushing device is provided, and a tank for receiving sewage is provided at the bottom of the garbage inlet. It is characterized in that a disinfectant spraying device provided with a spray nozzle that sprays toward at least one of the device or the pushing device is provided.

Further, the disinfectant injection device has an injection nozzle that pressurizes the disinfectant with an electric liquid feed pump that communicates with the disinfectant liquid tank and communicates with the pump via a liquid feed hose. The disinfectant injection device is also characterized in that the start of injection of the disinfectant is interlocked with the drive of the scraping device or the pushing device.

The disinfectant injection device sprays water from a spray nozzle when loading and collecting incombustibles to prevent dust accidents for loading workers standing behind the loading port and to discharge water to the loading port. By adding it, the risk of ignition can be suppressed, and even if it ignites and ignites, it can be ejected with an initial fire extinguishing hose installed separately from the spray nozzle to extinguish the initial fire and protect the vehicle from fire. It is also characterized by the fact that it exists.

According to the present invention, the foul odor of the garbage collection vehicle is deodorized by a simple device and a disinfectant that does not generate dioxin, and it is reduced that the foul odor is emitted to the outside of the vehicle and impairs the health of the collection worker and the surrounding residents.
