する（第４図）。 Figure 2 shows a suction check valve 1 installed in a suction pipe 10.
1 and 12 are enlarged cross-sectional views. The suction pipe check valves 11, 12, 14, and 15 all have the same structure. An inlet 41 is provided in the casing 41 of the suction check valve 11.
A and an outlet 41b are provided, and the inlet 41a communicates with the jet pump 35. A standpipe 42 is protruded inside the casing 41, and a valve seat 4 is mounted on the top of the standpipe 42.
3 is provided, and a valve body 44 is seated thereon. Valve body 4
4 is recommended, for example, a steel ball 45 surrounded by rubber 46 which is highly abrasive to the body. Guide plates 47, 47... are provided above the inner wall of the casing 40.
is provided, and when the valve body 44 is at the extreme position (double-dashed line), the center of gravity G of the valve body 44 is located at the center of the standpipe 42.
The movement is restricted so that it lies within the extension line l, l. An annular space S is formed between the casing 41 and the standpipe 42, and a first swash plate 48 having a downward slope toward the outlet 41b is provided in the annular space S. Adjacent to the highest position, second swash plates 49, 49 having a steeper slope than this are welded (FIG. 4).

ている。 The operation of the slurry concentrating and transporting device having the above configuration is as follows. Let's now assume that switching valves V 1 and V 4 are open, and switching valves V 2 and V 3 are in the closed position.
In that case, the discharge pressure of the main pump 22 is applied within the second tank 2, so the suction check valve 15 is closed.

４１ｂから排出されて第１タンク１に至る。 In FIG. 2, the slurry supplied from the jet pump 35 flows into the inlet 41a of the suction check valve 11, and as soon as the solid particles in the slurry flow out from the top opening of the standpipe 42, the slurry flows into the annular space S.
It falls with a thud and is then smoothly discharged from the outlet 41b while sliding while being guided by the steep slope of the second swash plate 49 and the slope of the first swash plate 48. Subsequently, the slurry flows into the inlet 41a of the suction check valve 12, is discharged from the outlet 41b, and reaches the first tank 1.

ラリー輸送管６により所定の場所に送られる。 Since the filter 18 allows only the water (working water) in the slurry to pass through, and not the solid particles, the solid particles remain in the first tank 1, and as a result, the slurry is concentrated. The working water further passes through the pipe 19, the switching valve V 1 and the suction pipe 24 to the main pump 2.
2, and from the discharge side to the discharge pipe 23 and the switching valve.
V 4 , the pipe 21, the second tank 2 via the filter 20
sent inside. This pressure water pushes out the concentrated slurry in the second tank 2, and the concentrated slurry is sent to a predetermined location by the slurry transport pipe 6 via the discharge pipe 7, discharge check valves 8 and 9.

輸送する。 After a certain period of time has elapsed, the hydraulic cylinder 17 is activated and the switching valves V 2 and V 3 are opened, and the switching valves V 1 and V 4 are switched to the closed position, and the discharge pressure of the main pump 22 is changed to the switching valve.
Since V 2 is added to the first tank 1 through the pipe 19,
The suction check valve 12 is closed, and the slurry from the stirring tank 30 flows into the second tank 2 through the suction check valves 14 and 15, and only the water (working water) in the slurry is filtered out by the filter 20. It is sucked into the main pump 22 via the pipe 21, the switching valve V 3 and the suction pipe 24. The working water discharged from the main pump 22 is sent into the first tank 1 through the discharge pipe 23, the switching valve V2 , and the pipe 19, and pushes out the concentrated slurry in the first tank 1, , the slurry is transported via the slurry transport pipe 6.

れる現象が起きにくい。[Effect of the invention] Since the standpipe 42 is provided protruding inside the casing 41 and the annular space S is formed between the casing 41 and the standpipe 42, the solid particles in the slurry are absorbed between the valve seat 43 and the valve body 44. As soon as it is released from the gap, it falls into this annular space S. Therefore, a phenomenon in which solid particles are trapped between the valve seat 43 and the valve body 44 is less likely to occur.
環状空間Ｓに第一斜板４８を設けたので、環

円滑に出口４１ｂから排出される。 Since the first swash plate 48 is provided in the annular space S, the solid particles falling into the annular space S do not accumulate in the space, but slide on the first swash plate 48 and are quickly and smoothly discharged from the outlet 41b. .

み現象を起こすことはまず考えられない。） Since the suction check valve 11 and the suction check valve 12 are arranged in series, when the discharge pressure of the main pump 22 is applied to the suction check valve, even if the suction check valve on the first tank 1 side 12 valve seats 43 and valve body 4
Even if solid particles are caught between the stirring tank 4 and the suction check valve 11 on the side of the stirring tank 30 to be unable to adhere to each other, the suction check valve 11 on the stirring tank 30 side will function normally and will not interfere with the operation. (It is highly unlikely that both check valves 11 and 12 would jam at the same time.)
