をうけ、その後の運転に支障をきたす。In such a slurry conveying machine, when the slurry to be conveyed contains solid foreign matters such as rocks, the solid foreign matters are clogged in the suction port of the pump and the amount of sludge conveyed decreases. In order to restore this to the original transport amount, it is necessary to stop the pump and remove solid foreign matter, resulting in poor transport efficiency. Further, when the solid foreign matter is caught in the rotating part of the pump, the pump is damaged, which hinders the subsequent operation.

However, the solid foreign matter contained in the slurry remains on the rotating body with protrusions. In that case, since the rotating body with protrusions is rotating around the horizontal axis from the upstream of the flow path toward the solid discharge port, solid foreign matter is sent to the rotating body with protrusions and discharged from the solid discharge port to the outside of the flow path. ..

A plurality of horizontal shafts 31 are pivotally supported between the side walls of the apparatus body 10, and a large number of protrusions 32 are fixed to each horizontal shaft 31.
Each protrusion 32 is an adjacent protrusion 32 of an adjacent horizontal shaft 31.
They are arranged so as to enter the spaces, and are arranged in a staggered manner in the entire flow path in plan view.

防止するためである。Next, the operation of the embodiment will be described. The slurry carried into the slurry carry-in port 12 by a bucket or the like hits the rotating body with protrusions 30, and the slurry itself flows between the rotating bodies with protrusions 30 and flows. It flows downstream of the path 11, enters the pump 50 from the slurry outlet 13, and is further transported downstream. In that case, since the slurry is urged to the downstream side of the flow path by the air flow from the air jet 40, even if the slurry has a high viscosity, the transportation is promoted and the transportation efficiency is enhanced. The reason why the slurry is not urged by the water flow of the pressurized water but is urged by the air flow is to prevent the water content of the slurry from increasing.

In that case, since the rotating body with protrusion 30 is rotating around the horizontal axis from the upstream side of the flow path toward the solid discharge port 20, the solid foreign matter is sent to the rotating body with protrusion 30 and outside the flow path from the solid discharge port 20. Is discharged to. Therefore, solid foreign matters such as rocks can be satisfactorily removed from the slurry, and the work of removing the solid foreign matters clogged in the flow path 11 is not required to improve the transfer efficiency, and the pump 50 is damaged by the entrapment of the solid foreign matters. Can be prevented and the slurry can be stably conveyed.
