BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a separation device for separating water and air from slurry during a slurry discharge process.

0002

2. Description of the Related Art Conventionally, when discharging slurry such as sludge, a pump was provided in a discharge pipe, and the pump sucked and discharged the slurry through the discharge pipe. In this case, in order to increase the transport efficiency, the suction flow rate of the pump may be set high.

0003

[Problem to be Solved by the Invention] Another possible method for discharging slurry without using a pump is to inject and supply air from an air ejector into the discharge pipe and discharging the slurry using air pressure. . In this case, in order to improve transportation efficiency, the amount of air supplied may be increased. but,
In either case, increasing the transport efficiency will increase the flow velocity of the slurry, and if the slurry contains a lot of sand and gravel,
There is a problem that sand and gravel hit the discharge pipe violently and cause damage. In particular, the vent part of the discharge pipe is hit hard by sand and gravel, and the damage is correspondingly large.

[0004] The present invention has been made with attention to these points, and its purpose is to reliably separate water and air from the slurry discharged by a pump or air, and to remove the slurry from the slurry. The goal is to improve the slurry transport efficiency while suppressing the flow rate to an appropriate level.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the solving means of claim 1 is such that a plurality of round bars are arranged in parallel without gaps in a casing so as to surround a slurry flow path. Both ends of the rod are fixed to the casing, and a midway portion of the round rod is elastically supported relative to the casing so as to be movable in the radial direction.

[0006] In addition to this configuration, the solving means of claim 2 has a configuration in which a vibrator for vibrating the round bar is attached to the casing.

[0007]

[Operation] According to the above structure, if this separation device is provided in the middle of the discharge pipe, when the slurry passes through the slurry flow path, there will be periodic gaps between the round bars due to the pulsation of the slurry. is formed, and water and air contained in the slurry are discharged into the casing through this gap. Therefore, the transportation efficiency is increased by separating water and air, and the flow velocity of the slurry is suppressed, thereby preventing damage to the discharge pipe due to sand and gravel in the slurry.

[0008] Furthermore, in the second aspect of the present invention, since the round bars are forcibly vibrated by the vibrator, the formation of gaps between the round bars is promoted, and the ability to separate water and air from the slurry is enhanced.

[0009]

[Embodiment] Hereinafter, an embodiment will be explained based on the drawings. This separation device consists of a discharge pipe (not shown) that discharges the slurry.
It is located in the middle of the. In FIGS. 1 to 3, 1
0 is a cylindrical casing, with a circular inlet 1 at one end.
1 and a circular outlet 12 at the other end, the flow path 2 allows slurry to flow between the inlet 11 and the outlet 12.
0 is formed. Then, the inlet 11 and the outlet 1
A discharge pipe is connected to 2, respectively.

In the casing 10, an annular groove 13 is provided on the inner wall around the inlet 11, and an annular groove 14 is provided on the inner wall around the outlet 12. Inside the casing, a large number of stainless steel round rods 30 are arranged in parallel without gaps so as to surround the slurry flow path 20.
The end portions 31 and 32 of are fitted into the annular grooves 13 and 14, respectively. The casing 10 includes each end 31 of the round bar 30,
32 to the casing 10, a pair of U bolts 41,
41 is installed. These U bolts 41, 41 are arranged vertically facing each other, and each end 31, 41 of all the round bars 30,
32 from above and below, and its end is fitted with a nut 42.
, 42 to the casing 10.

The casing 10 has a middle part 3 of the round bar 30.
A pair of U bolts 51, 5 supporting 3 on the casing 10
1 is installed. These U-bolts 51, 51 are arranged vertically to face each other, and embrace the middle portions 33 of all the round bars 30 from above and below, and their ends penetrate the casing 10. Spring holders 54,
55 is attached, and these spring holders 54, 55
A coil spring 53 is installed between them. 52
is a nut for fixing the spring holder 54. Therefore, the midway portion 33 of the round bar 30 is elastically supported with respect to the casing 10 so as to be movable in the radial direction (vertical direction in FIG. 1). 34 and 35 are natural rubber sheets provided between the ends 31 and 32 of the round bar 30 and the annular grooves 13 and 14; 36 is the middle part 33 of the round bar 30;
This is a natural rubber sheet provided between the U-bolts 51, 51.

Then, as shown in FIG. 3, the casing 1
A known vibrator 60 is attached to the rod 0 to vibrate the round bar 30.

Therefore, according to the above embodiment, when the slurry enters the separation device from the discharge pipe and passes through the slurry flow path 20, the round bar 30 moves in the radial direction (up and down in FIG. 1) due to the pulsation of the slurry. direction), and gaps are periodically formed between the round bars. Therefore, the water contained in the slurry is discharged into the casing through the gap formed between the lower round bars, and the air contained in the slurry is discharged into the casing through the gap formed between the upper round bars. Therefore, the efficiency of transporting the slurry is increased by separating water and air, and the flow velocity of the slurry is suppressed, thereby preventing damage to the discharge pipe caused by sand and gravel in the slurry. Also,
Since the round bars 30 are forcibly vibrated by the vibrator 60, the formation of gaps between the round bars is promoted, and the ability to separate water and air from the slurry is enhanced.

[0014] Here, the vibrator 60 does not necessarily need to be attached, and the pulsation of the slurry alone can function satisfactorily as a separating device.

[0015]

As explained above, in the separation device for slurry discharge according to claim 1, a plurality of round bars are arranged in parallel in a casing so as to surround a slurry flow path, and the round bars are arranged in parallel without gaps. Both ends are fixed to the casing, and the middle part of the round bar is elastically supported against the casing so that it can move in the radial direction, allowing water and air contained in the slurry to be discharged into the casing through the gaps between the round bars. In addition to increasing transportation efficiency by separating water and air,
The flow velocity of the slurry is suppressed, and damage to the discharge pipe due to sand and gravel in the slurry can be prevented.

Further, in the separation device for slurry discharge according to claim 2, since a vibrator for vibrating the round bars is further attached to the casing, the formation of gaps between the round bars is promoted and water and air from the slurry are removed. can increase the separation ability of
