Abstract
The present invention in the automatic waste transport system for forcibly transporting the food waste (referred to the garbage contained in the garbage bag) and the like discharged through the common passage from each generation, such as apartments to the garbage dump by the vacuum pressure formed inside the steel pipe, Since the knife of the knife gate valve is not exposed to the outside, it reduces the emission of odor due to food, and when the knife descends, the inclined surface of the valve seat and the inclined surface of the knife end are in close contact with each other to achieve a perfect sealing and minimize the space of the coupling groove To easily cut and to minimize the noise caused by contact with the valve seat when the knife is lowered by the buffer member mounted on the valve seat,
Knife gate valve for opening and closing device of the automatic waste transport system according to an embodiment of the present invention,
It is installed to be opened and closed in a waste conveyance pipe for transporting the waste collected and discharged through the common passage from each household of the apartment house, and the garbage accumulated in the waste transport pipe is forcibly stored in the garbage collection place by the vacuum pressure formed inside the waste transport pipe. In the knife gate valve for opening and closing device of the automatic waste conveying system to convey,
Knife passage is formed inside, the valve body which is communicated with the waste conveying pipe and the through hole through which the waste is passed is formed at the lower side,
A knife which opens and closes the through hole during the elevation along the knife path by driving the lifting means mounted on the valve body, and a cutting surface is formed at the edge of the inclined surface formed on one side;
The lifting means minimizes the space of the coupling groove for supporting the cutting surface of the knife when the knife is lowered, and includes a sealing valve seat for sealing the through-holes by the inclined sheet surface in close contact with the cutting surface of the knife.
Description
According to the present invention, food waste (referred to as trash contained in a plastic bag) and the like discharged through a garbage inlet from each household, such as apartments and apartment houses, are disposed in the garbage storage by using a waste transport pipe (polyurethane coating layer is formed on the inner side). In the case of forcibly conveying, the present invention relates to a knife gate valve for opening and closing device of an automatic waste conveying system, which is installed to be opened and closed on one side of a conveying pipe.
More specifically, in an automatic transfer system for suctioning and transporting waste at a predetermined speed (30 to 60 m / s) by vacuum pressure formed inside the waste transport pipe (suction type), a knife gate valve ( In the following, the automatic conveyance of the wastes minimizes the exposure of the knife from the "valve", reduces the noise generated when the valve closes the conveying passage of the conveying pipe, and improves the sealing effect due to complete cutting of the waste. Knife gate valve for the switchgear of the system.
Garbage contained in the garbage bag discharged through the common transport passage used by each household, such as apartments, is passed through the waste conveying pipe with the vacuum pressure inside and forcedly transferred to the garbage dump at a constant speed. Automatic waste transport system is used to remove the odors from the odor to create a comfortable living environment, and to save the trouble of collecting garbage in a fixed place on a fixed date.
According to an embodiment of the present invention, when the garbage is discharged from each household of the multi-family house to the garbage inlet, the garbage accumulated through the common waste passage is forced to the garbage dump through the transfer tube by the vacuum pressure formed inside the waste transfer tube. In a waste automatic conveying system for transporting, it is related to a knife gate valve for an opening and closing device of a waste automatic conveying system which minimizes the exposure of the knife when opening the valve to ensure safety.
The embodiment of the present invention, when the knife of the valve to the body seat to close the transport passage of the waste conveying pipe to reduce the noise generated to ensure reliability, and after cutting the garbage complete sealing is made of food waste It relates to a knife gate valve for an opening and closing device of an automatic waste conveying system which can prevent odor emission from the back.
Embodiment of the present invention, by maintaining the vertical direction when opening and closing the valve to prevent deformation and damage when the knife is repeatedly moved, improve the durability of the valve to reduce the after-care costs of the automatic waste transport system Related to knife gate valves for switchgear.
Knife gate valve for opening and closing device of the automatic waste transport system according to an embodiment of the present invention,
It is installed to be opened and closed in a waste conveyance pipe for transporting the waste collected and discharged through the common passage from each household of the apartment house, and the garbage accumulated in the waste transport pipe is forcibly stored in the garbage collection place by the vacuum pressure formed inside the waste transport pipe. In the knife gate valve for opening and closing device of the automatic waste conveying system to convey,
Knife passage is formed inside, the valve body which is communicated with the waste conveying pipe and the through hole through which the waste is passed is formed at the lower side,
A knife which opens and closes the through hole during the elevation along the knife path by driving the lifting means mounted on the valve body, and a cutting surface is formed at the edge of the inclined surface formed on one side;
The lifting means minimizes the space of the coupling groove for supporting the cutting surface of the knife when the knife is lowered, and includes a sealing valve seat for sealing the through-holes by the inclined sheet surface in close contact with the cutting surface of the knife.
According to a preferred embodiment, it includes a balancing adjustment member for pressing the upper side of the inclined surface of the knife to maintain the vertical direction when the cut surface and the valve seat of the knife lowered by the driving of the above-mentioned lifting means.
It is formed on the sheet surface of the valve seat to be in contact with the cutting surface of the knife described above, and includes a buffer member for reducing the noise due to contact with the cutting surface when the knife is lowered by the driving of the lifting means.
Knife gate valve of the automatic waste conveying system according to an embodiment of the present invention configured as described above has the following advantages.
Garbage collection system from each household, such as apartment houses, is installed to be opened and closed on one side of the transport pipe and discharged through the common passage of garbage, and is automatically transported to the garbage dump by the vacuum pressure formed inside the transport pipe. Knife gate valve for the opening and closing device of the switch, the knife is not exposed to the outside to minimize the discharge of odor of food, the inclined surface of the knife is in close contact with the inclined valve seat surface when the knife descends, the sealing is completed, Garbage can be easily cut by minimizing space, and when the knife is raised, the inclined surface of the knife removes the residue on the upper flow path.
In addition, it is possible to minimize the noise generated due to contact with the cutting surface of the knife when the knife is raised and lowered by the noise-absorbing buffer member mounted on the valve seat surface.
In addition, by maintaining the vertical direction when opening and closing the knife, to prevent the deformation and damage of the knife due to the pressurized garbage, etc. transported at a constant speed (30 ~ 60m / s) by the pressure, to improve the durability of the valve parts Aftercare costs can be reduced.
