Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solid separating apparatus for separating solids from slurry conveyed by a slurry conveying machine.

[0002]

2. Description of the Related Art Conventionally, when a slurry such as sludge is conveyed, a pump is provided in the conveying pipe, and the slurry is sucked and conveyed through the conveying pipe.

[0003]

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, and the operation thereafter is hindered.

The present invention has been made by paying attention to such a point, and an object of the present invention is to provide a solid separator for removing only solid foreign matter from the slurry to be conveyed.

[0005]

In order to achieve the above object, the invention of claim 1 is directed to a solid separating apparatus of a slurry conveying machine for separating solids from conveyed slurry. On the other hand, on the other hand, the apparatus main body that forms a flow path in the vertical direction, the solid discharge port provided on the side wall of the apparatus main body in communication with the flow path, and the flow path at the same height as the solid discharge port. And a plurality of rotating bodies with protrusions that rotate around the horizontal axis from the upstream side of the flow path toward the solid discharge port .
It has a configuration in which Ru is provided an air jet downstream of the rotating body with protrusions.

[0006]

With the above structure, in the invention of claim 1, the slurry carried in from the upstream of the flow path hits the rotating body with the projections, and the slurry itself passes between the rotating bodies with the projections and flows downstream of the flow path. However, the solid foreign matter contained in the slurry remains on the rotating body with protrusions. In this case, since the rotating body with protrusions is rotating around the horizontal axis from the upstream side of the flow path toward the solid discharge port, the 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. . Further, since the slurry that has passed between the rotating bodies with protrusions is urged to the downstream side of the flow path by the air flow from the air jet, the slurry transfer is promoted.

[0007]

Embodiments of the present invention will now be described in detail with reference to the drawings. In FIGS. 1 to 3, reference numeral 10 denotes a cylindrical apparatus main body, a slurry carry-in port 12 is opened at the upper end, and a slurry carry-out port 13 is opened at the lower end, and a flow path 11 in the vertical direction is formed therebetween. A solid discharge port 20 is provided on the side wall of the apparatus body 10 so as to communicate with the flow path 11. A cylindrical guide 21 is connected to the solid discharge port 20. Then, the slurry is supplied to the slurry carry-in port 12 by a bucket (not shown) suspended by a crane. A rotary type pump 50 is connected to the slurry carry-out port 13.

Further, a large number of rotating bodies with protrusions 30 are provided in the flow path 11 in parallel at predetermined intervals. That is,
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. A sprocket (not shown) is fixed to one end of the horizontal shaft 31, and a motor and a speed reducer (both not shown) for decelerating the motor are attached to the side of the apparatus main body 10. Each sprocket and the output shaft of the speed reducer are attached. A chain is wound between and, and by driving the motor, the rotating bodies 30 with protrusions are rotated around the horizontal shaft 31 in the direction from the upstream of the flow path toward the solid discharge port 20 (clockwise in FIG. 1). I am letting you. The rotating body with protrusion 30 is provided at substantially the same height as the solid outlet 20, and is pivotally supported at a higher position toward the solid outlet 20. Further, 33 is a large number of guide blades fixed to the apparatus body 10 between the series of rotating bodies with protrusions 30 and the solid discharge port 20, and 34 is a large number of guide blades fixed to the apparatus body 10 on the opposite side. Is.

Further, the rotating body with protrusion 30 of the apparatus body 10
Four air jets 40 are provided in the four corners downstream of the flow path 1
1, the compressed air is supplied to each air jet 40.

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. It flows downstream of the path 11, enters the pump 50 from the slurry outlet 13, and is conveyed further 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.

On the other hand, the solid foreign matter contained in the slurry remains on the rotating body with protrusions. In that case, since the rotating body with protrusions 30 is rotating around the horizontal axis from the upstream of the flow path toward the solid discharge port 20, the solid foreign matter is sent to the rotating body with protrusions 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.

Although the slurry is carried into the flow path 11 by a bucket or the like, it may be carried in by other means. Channel 1
Although the pump 50 is connected to the downstream side of 1, the other transport machine may be connected. Further, the rotary body with protrusion 30 is not limited to the one in the embodiment, and the protrusion may be formed on the surface of the rotor. Further, although the guide 21 is connected to the solid discharge port 20, the guide 21 is not an essential member. Further, four air jets 40 are provided at the four corners,
The number is not limited as long as it is provided on the downstream side of the rotating body with protrusion 30.

[0013]

As described above, according to the solid separating apparatus of the slurry conveying machine of the first aspect, among the slurries carried in from the upstream of the flow path, the slurry itself is passed through between the rotating bodies with protrusions. flow downstream of the road, the solid extraneous Ri sent to the solid discharge outlet by rotating body with protrusions, passes between the projections with the rotary body
The slurries under the flow path by the air flow from the air jet
Flow to urge to Runode, slurry solid extraneous can be satisfactorily removed from, to increase the conveying efficiency eliminates the need for work such as removing solid foreign matter jammed in the channel, damaging the pump by biting of solid extraneous It is possible to stably and efficiently carry the slurry by preventing such problems .
