Description

DETAILED DESCRIPTION OF THE INVENTION The present invention uses a suction device that combines a bubble pump and a jet pump to suck up a liquid mixed with earth, sand, and other solids, and then a relay tank is provided.
Once the liquid and solids are separated and discharged, a relay pump is installed in the drain pipe, and the discharge port of the relay pump is opened into the solids discharge pipe, making it possible to transport the solids mixed liquid horizontally. It is related to the device. Hitherto, a suction device combining a bubble pump and a jet pump has been known, but although this device has a vertical suction action, it does not have a horizontal conveying action. Furthermore, Jikko 49-
I hope something like No. 19925 will be disclosed,
The jet flow in this plan is not parallel to the suction direction of the pipe and is not injected into the center of the pipe, so there is a drawback that the jet flow cannot fully demonstrate its efficiency, and once it has suctioned in the vertical direction, , there is no effect of conveying the solids-containing liquid in the horizontal direction.

The present invention has the function of vertically sucking up liquid mixed with solids with high efficiency, and at the same time conveying it horizontally without any hindrance, so it can be used in underground construction work for buildings, sewage treatment work, etc. It is especially effective.

I will now explain in detail the accompanying drawings showing one example of implementation.

Reference numeral 1 denotes a suction tube which is inserted into a liquid containing solids, such as water mixed with earth and sand, and sucks up the mixed liquid. 2 has a bent shape at the outlet of the pipe, and the pressure water from the pressure water pipe 10 is injected from the injection nozzle 11 as a jet stream 13 parallel to the suction direction at the center of the pipe 1. By injecting the jet flow parallel to the suction direction of the pipe that sucks up the mixed liquid, the jet pump works more efficiently than when the jet flow is injected from a direction that is not parallel to the suction direction of the suction pipe. It is something to do. Reference numeral 4 denotes a discharge pipe that sucks up and discharges the liquid containing solids. Reference numeral 5 denotes a forced air pipe (or hose); 6 an air chamber surrounding the outer periphery of the inlet 12 of the suction pipe; It is something that communicates within. Reference numerals 8 and 9 are valves for pressurizing compressed air into the air chamber 6, and these parts have the function of a bubble pump. 16 is a rising bubble. Incidentally, when the pressure at the suction pipe inlet 12 is higher than atmospheric pressure, the forced air pipe 5 communicates with a compressor (not shown) and is controlled to be forced by a valve 8. If the pressure at the suction pipe inlet 12 is less than atmospheric pressure, the forced air pipe 5 need only communicate with the atmospheric layer via the flow rate regulating valve 9. Air is pushed into the tube through the push-in port 7, becomes bubbles 16, and rises rapidly in the suction tube, causing an upward movement of the solid mixture. In the middle of the suction pipe, pressurized water is fed into the pressure water pipe 10 by a pump (not shown), and as described above, the cross-sectional area is narrowed by the injection nozzle 11, and the water is discharged at high speed into the pipe. It sprays in parallel directions. As described above, the liquid material mixed with earth and sand is urged to rise even more efficiently. In this way, the bubble pump action works by suction in the upward direction, but once it has been raised to the ground, it does not have any pressing force when attempting to transport it laterally in any horizontal direction. . However, if a liquid material containing solid matter such as earth and sand is forced in the lateral direction by an ordinary turbine pump, etc., a large amount of air due to bubbles and a mixture of solid matter will cause the conventional turbine pump, etc. cannot be adopted. Therefore, in the present invention, an interruption tank 20 is installed at the rising end of the suction pipe 1, and its unique action provides a strong horizontal force. That is, 22,
23 and 24 are screens installed in the suspended tank, the base end of which is fixed to the suspended tank in stages, and the tips of which are each inclined downward.These screens can be used to hold solid materials of various thicknesses such as coarse, medium, and fine. It is separated from the liquid while being careful not to cause clogging, etc. 28 is an air vent. A drain pipe 30 exits from the bottom of the relay tank 20 and is pressurized by a pressurizing pump 27 midway through. In this case, since the solid matter is separated and only water exists in the drain pipe, the discharge pipe can be pressurized and discharged without any problem even with an ordinary turbine pump.
A suction pipe 25 injects pressurized air from a forced air pipe 26 to suck up solid matter in the relay tank. Here, the pressure water pressurized by the pressure pump 27 is injected from the discharge port 29 into the solid matter suction pipe 25, and becomes pressure water mixed with solid matter again in the horizontal direction. It will be transported. When transporting over a long distance in this way, a device similar to the relay tank 20 in the present invention can be interposed in any number of stages to transport the solids to the desired location. It is possible to vertically suck up liquid substances, and also to arbitrarily transport the sucked up liquid mixed with solid substances in the horizontal direction, which is extremely effective.
