Field of the Invention The present invention relates to a sludge pumping device for pneumatically transporting sediment and sludge to a remote place while selectively removing rocks and other foreign matter from sediment and sludge collected at a mining site or a dredging site, and particularly to clay.

As a device for transporting after removing rocks and foreign substances from these clays, conventionally, for example, as shown in FIG. 5, the clays are put into a hopper 3 provided with a vibrating screen 2 inclined at the top, and the clay is placed on the screen. Rocks and foreign substances are transferred by the waste discharge conveyor 9, and the clay under the sieve is extracted from the two discharge ports of the hopper 3 by the screw feeder 4, and the inlet valve 5 and the outlet valve 7 are arranged in front and rear. After alternately storing in the pressure-feeding tank 6, the compressed air is fed through the discharge pipe 8 by pressure. Further, as shown in FIG. 6, after the clays received in the vibrating screen 2 are sorted out for foreign matter, three hoppers (upper hopper 3a, intermediate hopper 3b,
A conventional method has also been practiced in which the lower hopper 3c) is sequentially flown down, and each is conveyed by the screw feeder 4 while being discharged by the pressure pump 10 and blowing compressed air from the ejector 8a into the discharge pipe 8 to convey the compressed air.

合があった。However, in both of the methods shown in FIGS. 5 and 6, the vibrating sieve 2 is located in one place, and the mesh of the vibrating sieve 2 cannot be so large. Since it is difficult to transfer the clay and the large lump of clay cannot pass through the mesh, it is difficult to discharge the target under-sieved clay, and the sorting efficiency of the vibrating sieve is poor, and There was an inconvenience that the crushing was not performed sufficiently.

Therefore, rocks and foreign substances can be transferred smoothly on the vibrating screen. Most of the clay lumps that have passed through the primary vibrating sieve are crushed by the impact when they fall onto the secondary oscillating sieve, and the uncrushed clay lumps are crushed by the jet of high-pressure water, and the secondary vibration Pass through the sieve. In this way, the sediment and sludge that have fallen and accumulated in the clay tank are agitated and transferred, discharged through a vertical screw conveyor by a pressurizing pump, and then plugged by compressed air in the discharge pipe. In particular, for clay lumps that are difficult to pass through the secondary vibrating sieve, not only a fixed jet nozzle but also a movable jet nozzle is provided to partition the clay lumps and perform sufficient crushing to facilitate passage through the vibrating sieve. Considered to do.

The three-arm rotor 220 presses the protrusions 220c on the inner surface of the casing 220b alternately by the low-speed rotation of the three-blade rotor 220a inside, so that the casing 220b intermittently reciprocates. Then, the movable water injection pipe 40B is configured to move forward and backward at a low speed with a fixed rest time. The reciprocating speed of the movable water injection pipe 40B is arbitrarily adjusted by controlling the rotation speed of the reduction motor 210. Inside the mud tank 50, the accumulated processed material is agitated,

搬送される。The operation of the sludge pumping apparatus 1 of the present invention constructed as above will be described. When the backhoe 18 puts the processed product in the hopper 20a and energizes the primary vibrating screen 20 and the secondary vibrating screen 30, the rocks and foreign matters larger than the mesh of the primary vibrating screen 20 and the secondary vibrating screen 30 among the processed products are removed. Each overflows and is conveyed by the conveyor 60. 1
The lumps of soil such as clay blocks that have passed through the secondary vibrating screen 20 are crushed by the impact of falling onto the transported product falling range 30a of the secondary vibrating screen 30, and those smaller than the mesh of the secondary vibrating screen 30 remain as they are. Although a hard clay lump, which passes through, is decomposed by spraying high-pressure water with a fixed jet nozzle 40a, the clay lump that has not been crushed still overflows if left as it is, which is unsatisfactory. Therefore, as shown in FIG. 2 and FIG. 3, the movable jet nozzle 40b is reciprocated in the direction orthogonal to the raw material flow by rolling the secondary vibrating screen 30 in the inclined direction, and the fixed jet nozzle 40a is used to reciprocate the raw material flow. In addition to cutting in the direction, the cutting force by the high-pressure jet water was also activated in the direction orthogonal to the flow direction of the raw material to cut a clay lump that was much larger than the mesh of the sieve mesh into a mesh-like lattice. In this way, the fixed jet nozzle 40a and the movable jet nozzle 40b cooperate with each other to finely divide the clay lump and pass it through the mesh. The treated substances (sludge, earth and sand, clay, etc.) accumulated in the mud tank 50 are stirred and mixed together with the poured water by the stirring device 50a, and then introduced into the intake of the vertical screw conveyor 70 at one end of the mud tank 50. Transferred, screw 70
It is raised by the rotation of a, is discharged from the upper discharge port, and is supplied to the discharge pipe 80. The processed material in the discharge pipe 80 is pressurized by the pressurizing pump 90, and is then plug-transported by the compressed air injected from the ejector 100 to be pneumatically transported to a remote destination.

る。As described above, in the sludge pumping device 1 of the present invention, the processed product of the conventional device shown in FIGS. 5 and 6 moves downward due to the head pressure due to the stacking height of the processed product itself. In contrast to the vertical screw conveyor 70
Since it is strongly transferred by the mechanical transport action by the, it is possible to strongly take in even a small lump, so that the mesh of the secondary vibrating sieve 30 can be enlarged by that amount, and once it is taken into the screw, the rotation of the high-speed screw rotates. In addition to the transfer action, the action facilitates the agitation fluidization and thus facilitates the subsequent transfer. In addition, since the vibrating screen has two stages, it is not only easy to remove rocks and foreign materials, but also the mesh of the primary vibrating screen can be made much larger than that of the secondary vibrating screen, so that the sand itself can pass through. It's very smooth. The conventional ones shown in FIGS. 5 and 6 have only one stage of vibrating sieve, and the mesh size is inevitably reduced. Further, in the present invention, the clay mass that needs to be treated is crushed when it falls on the secondary vibrating sieve, and is forcedly crushed with a fixed jet nozzle or a movable jet nozzle accompanied by a grid-like cutting by a high-pressure jet water flow. As it passes through the mesh, it is possible to avoid mixing with rocks and foreign matter.
