Description

[Detailed description of the invention] This invention relates to a hopper device for discharging screen waste separated from sewage and other waste water. A drain gutter and a curtain drum wrapped with curtains that hang down on both sides are provided, and when the hopper is opened, the sewage receiving gutter is moved from directly below the hopper to the side to escape from falling objects in the hopper, and the hopper is also moved. In conjunction with this, the curtain is lowered and extended to both sides by the rotation of the curtain drum, and when the hopper is closed, the sewage receiving trough and the curtain are returned to their original state.

Hereinafter, the present invention will be explained with reference to one embodiment shown in the drawings. FIG. 1 is a front view of the device of the present invention, FIG. 2 is a side view, FIG. 3 is a plan view, and FIG. It is a cross-sectional view, and in the figure, 1 is a hopper, 2 is a sewage receiving gutter, 3 is a trolley, 4a and 4b are curtain drums, and 5
are the above-mentioned sewage receiving gutter 2 and curtain drums 4a, 4b.
6 is the same handwheel, 7 is the entrance floor, 8 is the frame, 9 is the drainage gutter, 10
indicates a drain pipe, and each part is constructed as follows.

The hopper 1 has an opening/closing plate 1a on both sides of the lower part,
1b is attached by each hinge 1c, 1d, approximately
When closed by rotating 45 degrees, they are aligned below the center of the hopper, and when opened, they are in an almost vertical position. The opening/closing plates 1a, 1b are opened and closed by an opening/closing cylinder 11 and arms 14, 15 connected to the tip of a rod 12 by a joint 13, respectively. The base of the opening/closing cylinder 11 is pivotally connected to a fixed support part 16, and one end of the arm 14 is pivotally connected to a fixed support part 17. By extension, the arms 14 and 15 are stretched in a straight line as shown in Fig. 1 to hold the opening/closing plates 1a and 1b in a closed state, and by the contraction of the rod 12, the arms 14 and 15 are broken at the joint 13 and the arms are 15 through the opening/closing plates 1a, 1
b is rotated to a vertical position and held open.

The sewage receiving gutter 2 has the opening/closing plate 1 closed as described above.
Parallel to the intersection of a and 1b, both ends of the trolley 3
The trolley 3 is supported on the rail 19 on the frame 8 so that it can run from just below the above-mentioned joint to one side.

The curtain drums 4a, 4b are supported parallel to both sides of the wastewater receiving trough 2 by shafts 41, 42 and pillow-shaped units 43, 44 of bearings, respectively.

The handwheel 6 is supported by a shaft 61 and a pillow-shaped unit 62 of a bearing, and the shaft 41 is driven by the sprocket wheel 21 from the shaft 61, the chain 22, and the sprocket wheel 23 on the shaft 41 to rotate the curtain drum 4a. At the same time, the sprocket wheel 24 at the other end, the chain 25, and the sprocket wheel 26 at the other end of the curtain drum 4b
The curtain drum 4b is rotated to raise and lower the respective curtains 4c and 4d.

Further, sprocket wheels 24, 26, 27, 28 are provided on the shafts 41, 42, and both ends of chains 25, 29 are connected to the waste water receiving trough 2, and the chains 25, 29 are connected to the sprocket wheels 24, 26, 27, 28. 2
4, 26, 27, 28, and as the shaft 41 rotates, the sprocket wheels 24, 26, 27, 28
The sewage receiving gutter 2 is connected to the trolley 3 via the chains 25 and 29.
Together with this, the rail 19 is moved from one end to the other end.

The drainage gutter 9 is provided at the position shown in FIGS. 1 and 3 so as to receive the sewage flowing down from the outlet 2a provided at one end of the sewage receiving trough 2, and to make it flow to one side. Even during the movement of the drain gutter 9, the waste water flows into the drain gutter 9 from the flow outlet 2a, and a drain pipe 10 is connected to the end of the drain gutter 9 so as to guide the waste water downward.

With the above configuration, the opening/closing plates 1a, 1 of the hopper 1
The opening/closing cylinder b is held in the closed state as shown in FIG. 1a, 1b
When the screen sludge is opened and the screen scraps are loaded into a carry-out truck or the like, the sewage receiving trough 2 can be evacuated to the side and the curtains 4c and 4d can be extended hanging down on both sides before the screen dregs are loaded.

As mentioned above, when the opening/closing plates 1a and 1b of the hopper 1 are closed, there is a sewage receiving trough 2 directly below the joint, and the sewage flowing down from the joint is received by the receiving trough 2 and flows through the outlet at the end. Since waste water is discharged from 2a through a drain gutter 9 and a drain pipe 10, the waste water is prevented from flowing down onto the loading floor 7 before the unloading truck or the like enters the vehicle, thereby preventing soiling.
When loading the screen scraps onto a carry-out truck, etc., first operate the hand chain 5 to open the sprocket wheel 2 before opening the hopper opening/closing plates 1a, 1b.
1, the curtain drum 4a on one side via the chain 22 and the sprocket wheel 23, and the sprocket wheel 24, the chain 25, and the sprocket 2.
The curtain drums 4b on the other side are rotated through the curtain drums 6 to extend the curtains 4c and 4d in a drooping manner.
At the same time, the sewage receiving trough 2 moves due to the rotation of the sprocket wheels 24, 26, 27, 28 on the shafts of the curtain drums 4a, 4b and the chains 25, 29, and the sewage receiving trough 2 is moved by the opening of the opening/closing plate 1a on one side. The screen scum falling from the hopper 1 is displaced in the same direction as the screen scum falling from the hopper 1, and the screen scum falling from the hopper 1 reaches a position away from the falling position of the screen scum in the hopper. There is no risk of getting caught in the sewage receiving gutter 2 or giving impact.

After the screen dregs are discharged in this way, the hopper opening/closing plates 1a, 1b opening/closing cylinders 11
Closed by the sewage catch trough 2 and curtain drum 4
a and 4b are restored to their original states by operating the hand chain 5, and wait for the next screen waste disposal.

The present invention has the above-mentioned configuration and functions, and the sewage that falls from the joint between the opening and closing plates of the hopper containing screen waste can be received by the sewage receiving gutter directly below the sewage gutter, and then conducted and disposed of elsewhere by the drain gutter. Therefore, there is no risk that the entrance position of the unloading truck, etc. below the hopper will be contaminated by falling sewage, and when the hopper opening/closing plate opens and the screen residue falls, the sewage receiving gutter can be moved to the side. At the same time, the curtains are hung down from the curtain drum on both sides to prevent screen debris and sewage from scattering to the sides.
This is an excellent idea with great practical benefits.
