Description

A rubbish exhaust valve used in auto cleanet}

The present invention relates to a waste discharge valve for an auto clean net equipment, and more particularly, in a waste transport system for transporting household waste, to maximize the sealing property of the waste inlet part, and to prevent leakage of toxic substances to the outside and the outflow of odor. To prevent the malfunction of the waste transportation system due to fire or vacuum leakage in the temporary storage unit, thereby realizing a perfect seal between the temporary storage unit and the transfer pipe. It is about.

Garbage transport systems (also known as centralized waste disposal systems) installed in residential complexes such as large apartments, officetels, and commercial complexes are provided with transport pipes from the garbage dumps, and the input pipes for each household or indoor / It is a system that diverts the input pipe vertically to other public input ports and transfers the garbage put into the input pipe through the input slot for each household or the indoor and external public input ports to the garbage collection place by vacuum suction force.

This waste transport system is installed between the input pipe and the transfer pipe when the waste put into the input pipe is accumulated in the temporary storage of the input pipe, and when the height of the garbage accumulated in the temporary storage reaches a certain level, it is detected by the level sensor. The waste discharge valve is opened to drop the waste accumulated in the temporary storage unit into the transfer tube, and the waste dropped in the transfer tube is transferred to the garbage collection place by vacuum suction force.

In the conventional waste conveying system, since the waste put into the input pipe is temporarily stored in the temporary storage unit and then discharged, harmful substances generated from the waste accumulated in the temporary storage unit are leaked to the outside or the odor is injected into the inlet. It leaks outside and easily penetrates into the living space of the residents, and when rainwater or moisture enters from outside exposed areas such as inlets, garbage stored in the temporary storage area is spoiled and causes a bad odor. Development is urgent.

In addition, the waste discharge valve that opens and closes between the temporary storage portion and the transfer pipe of the waste input pipe completely seals between the input pipe and the transfer pipe to prevent leakage of vacuum suction force when transferring the waste from other input pipes other than the corresponding input pipe. Only when the waste is smoothly transported in the transfer pipe, no waste of energy or systemic error occurs.

However, since the opening and closing valve of the conventional temporary storage part also serves to substantially support the weight of the garbage accumulated in the temporary storage part, the valve plate is sag due to the weight of the garbage accumulated in the temporary storage part, thereby deforming locally or entirely. Therefore, a gap is generated between the valve plate and the valve seat.
