DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which is intended to explain in detail enough to enable those skilled in the art to easily practice the present invention. This does not mean that the technical spirit and scope of the present invention is limited.

As shown in Figure 1 to 5, the knife gate valve for the 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,

The knife passage 11 is formed therein, the valve body 14 which is communicated with the waste conveying pipe 12 and the through-hole 13 through which waste is passed is formed at the lower side,

An inclined surface 15 formed on one side to open and close the through hole 13 when the elevating means 10 (the air cylinder is used) mounted on the upper portion of the valve body 14 is moved along the knife passage 11. The knife 17 is formed with a cutting surface 16 at the edge of,

Driven by the lifting means 10 to minimize the space of the coupling groove 23 for supporting the cutting surface 16 of the knife 17 when the knife 17 is lowered, and is in close contact with the cutting surface 16 of the knife 17 A sealing valve seat 19 for sealing the through hole 13 by the inclined sheet surface 18 is included.

When the cut surface 16 of the knife 17 lowered by the driving of the elevating means 10 and the valve seat 19 come into contact with each other, the inclined surface of the knife 17 so as to keep the knife 17 in the vertical direction ( 15) Balancing adjustment member 20 (for example, a bolt is used) for pressing the upper side.

It is formed on the sheet surface 18 of the valve seat 19 to be in contact with the cutting surface 16 of the knife 17 described above, and in contact with the cutting surface 16 when the knife 17 is lowered by the driving of the lifting means 10. And a shock absorbing member 21 (for example, a rubber material NBR is used) for reducing noise caused by the same.

In the drawings, reference numeral 22 denotes a cylinder rod of the air cylinder, 24 denotes a sealing packing mounted to be in close contact with one side of the knife 17, 25 denotes a side cover fixed to the inlet side of the valve body 14, 26 is a common corridor for discharging waste from households such as apartments, and 27 is a garbage dump.

Hereinafter, with reference to the accompanying drawings an example of the use of the knife gate valve for the opening and closing device of the automatic garbage transport system according to an embodiment of the present invention will be described in detail.

As illustrated in FIG. 5, food wastes and the like are discharged in a garbage bag through the common passage 26 from each generation of the apartment house such as an apartment. At this time, the opening and closing device which is installed at a predetermined position of the waste conveying pipe 12 for transferring the waste collected in the common passage 26 to the waste collecting place 27 maintains the closed state. The vacuum pressure is formed in the waste conveying pipe 12b between the opening and closing device and the garbage storage 27 by the driving of a vacuum pump, which is not shown.

When a certain amount of waste accumulates in the waste conveying pipe 12a between the common passage 26 and the opening and closing device, the sensor detects by a sensor (not shown) and supplies a detection signal to the controller (not shown). Since the cylinder rod 22 is moved upward in the drawing due to the driving of the lifting means 10 (referring to the contraction driving of the air cylinder), the knife 17 is raised. That is, since the knife 17 is moved to the knife passage 11 of the valve body 14, the waste conveying pipe 12 is opened.

By the vacuum pressure formed inside the waste conveying pipe 12b, the waste is automatically conveyed toward the waste collecting place 27 while maintaining a predetermined speed. The rubbish transferred to the garbage dump 27 is transferred to a truck or the like and transferred to a designated place such as a landfill.

At this time, since the knife 17 moved to the knife passage 11 by the driving of the elevating means 10 is prevented from being received and exposed in the valve body 14, safety is improved. In addition, it is possible to minimize the outflow of odor generated from food waste and the like.

On the other hand, when the lifting means 10 is driven by the control means (not shown in the drawing), the knife 17 connected to the cylinder rod 22 through the shaft is lowered from the knife path 11. So close the waste transport pipe (12).

That is, the waste conveying pipe 12 is closed due to the close contact between the cut surface 16 formed at the edge of the inclined surface 15 of the knife 17 and the sealing valve seat 19. At this time, by the valve seat 19 mounted on the outlet side of the through hole 13, the space of the coupling groove 23 can be minimized to prevent food from being jammed.

In addition, the cutting surface 16 of the knife 17 and the sheet surface 18 of the valve seat 19 are completely in contact with each other, thereby completely cutting the waste, and sealing effect (blocking odor from food waste and leaking under vacuum). To exert a function of blocking).

On the other hand, when the knife 17 is lowered to close the waste conveying pipe 12, a cushioning member 21 (for example, a rubber material NBR) fixed to the sheet surface 18 of the valve seat 19 is used. ) Noise can be prevented.

When the cut surface 16 of the knife 17 and the sheet surface 18 of the valve seat 19 are in close contact with each other due to the lowering of the knife 17 as described above, the upper end of the knife 17 is shown in FIG. , Tilts to the right. At this time, the knife 17 can maintain the vertical direction by the balancing adjustment member 20 (for example, a bolt is used) for pressing the upper side of the inclined surface 15 of the knife 17.

For this reason, it is possible to prevent the parts supporting the knife 17 from being damaged or worn out due to the load caused by the waste accumulated in the waste conveying pipe 12a. Moreover, the sealing effect by the close contact of the cutting surface 16 of the knife 17 and the sheet surface 18 of the valve seat 19 can be raised.
