Description

The present invention relates to a waste treatment device provided in a pretreatment room of a septic tank facility installed in a toilet facility such as a SA (service area) or PA (parking area) of a highway.

Toilet facilities such as SA and PA on the National Expressway are equipped with septic tank equipment, and this septic tank equipment is pretreated for the first flow of waste including human waste and toilet paper generated when the user uses the toilet. There is a room. In the pretreatment room, a rough screen is arranged to remove the waste that cannot be treated in the septic tank (solid matter mixed with waste such as human waste discharged from the toilet). Lighters, precious metals, ornaments, mobile phones, smartphones, sanitary napkins, etc. are generally used as the residue.

The coarse screen is a belt conveyor type device having a plurality of rotating belts with protrusions, and has a function of scraping up solid matter mixed in filth with the rotating belts with protrusions. The solid matter scraped up by the coarse screen from the filth flowing from the toilet is collected in the waste basket installed below the coarse screen. On the other hand, the relatively small residue that has passed through the coarse screen is crushed into small pieces by a crusher and sent to a treatment tank provided in the subsequent stage.

Here, as a conventional technique related to the present invention, for example, there is a "dust removal / dehydrating device" described in Patent Document 1. In this "dust removal / dehydrating device", a cylindrical screen equipped with an extruder is arranged at the lower part of the inflow tank, and a conveyor is provided at the tip of the cylindrical screen so as to take out solid foreign matter from the upper part. It is characterized in that, in addition to connecting the above, a blower pipe for blowing drying air is connected into the transport cylinder.

Rough screens and waste baskets placed in the pretreatment room were inspected on a daily basis, and cleaning and operation checks were also carried out at this time, but they were collected in the waste baskets during the cleaning work. It takes a lot of labor and time to level the waste.

That is, the droppings collected in the droppings basket are piled up in a mountain shape, and if they are left as they are, the droppings will overflow and leak out, which will adversely affect the crushing work by the crusher placed after that. It is necessary to manually level the mountain-shaped sediment, and this leveling work requires a lot of labor and time.

In addition, some of the debris adhering to the coarse screen and the debris accumulated in a mountain shape on the debris basket dries and solidifies, leading to an increase in cleaning work (washing and leveling work), and the debris basket. There are problems such as clogging and a large amount of pulp-like toilet paper that can be processed by a crusher stays in the waste basket.
