(57) [Abstract] [PROBLEMS] To provide a screw conveyor device (10) capable of preventing foreign matters from co-rotating during transportation by a screw blade (18) and smoothly transporting foreign matters. [Structure] The screw blade 18 is coated with a surface lubricant such as Teflon or epoxy.
It is possible to prevent foreign substances from being attached to the cleaning water distribution pipe, arrange the cleaning water distribution pipe 20 in parallel with the rotary shaft 16 of the screw blade 18, and inject water from the water injection hole 22 of the cleaning water distribution pipe 20. Since the lump of foreign matters that are jammed during transportation is loosened, the foreign matters can be prevented from co-rotating and the foreign matters can be transported smoothly.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a screw conveyor device, and in particular, in the field of clean water and sewage treatment, a screw for transporting contaminants (dust) such as paper, vegetation, plastic, etc., which have been mixed and collected in the treated water into a trough or pipe. The present invention relates to a conveyor device.

[0002]

[Prior Art]

 Conventionally, this type of screw conveyor device has been equipped with a screw blade spirally attached to the surface of the rotating shaft, which rotates together with the rotating shaft, so that contaminants are sandwiched between the screw blades from one side of the trough or pipe. It is transported to the other side.

[0003]

[Problems to be solved by the device]

 However, in the conventional screw conveyor device, the contaminants gradually become clogged between the screw blades during the transportation of the contaminants, and the screw blades and the contaminants start to rotate together with it, which makes it impossible to convey the contaminants. There is. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a screw conveyor device capable of preventing foreign matter from co-rotating and smoothly carrying the foreign matter.

[0004]

[Means for solving the problem]

 In order to achieve the above-mentioned object, the present invention provides a rotary shaft having screw blades spirally attached to the surface thereof inside a trough or pipe for conveying foreign matters, and the rotary shaft is set in a predetermined direction. In a screw conveyor device that rotates the screw blade by rotating the screw blade to convey the contaminants from one side of the trough or the pipe to the other side, the screw blade is coated with a surface lubricant, and the shaft is A water distribution pipe in which a plurality of water injection holes are formed at predetermined intervals in the direction is arranged inside the trough or pipe and parallel to the rotation axis of the screw blade.

[0005]

[Action]

 According to the present invention, the screw blade is coated with a surface lubricant to prevent foreign matters from adhering to the screw blade. Furthermore, a water distribution pipe is arranged parallel to the rotation axis of the screw blades, and the water jetted from the water jet holes of this water pipe loosens the lumps of foreign substances that are blocked during transportation. As a result, it is possible to prevent the foreign matters from co-rotating between the screw blades, so that the foreign matters can be smoothly transported.

【Example】

 Hereinafter, a preferred embodiment of a screw conveyor device according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 shows an embodiment of a screw conveyor device 10 according to the present invention. As shown in FIG. 2, the screw conveyor device 10 has a screw conveyor 14 arranged in a trough 12 having a semi-circular cross section.

The trough 12 is provided to convey contaminants such as paper and vegetation collected in the sewage treatment plant in the pipe. The screw conveyor 14 is configured by screwing blades 18 in a spiral shape on a rotating shaft 16. Further, the rotating shaft 16 is connected to a motor (not shown) and is rotated in the direction of the arrow in the figure by the rotational force transmitted from this motor. As a result, when the screw blades 18 rotate as the rotary shaft 16 rotates, the foreign substances (not shown) in the trough 12 are sandwiched between the screw blades 18 and conveyed in the direction of the arrow in the figure.

The screw blade 18 is coated with a surface lubricant such as Teflon or epoxy so that the surface of the screw blade 18 is unlikely to be contaminated with impurities during transportation. Further, a water distribution pipe 20 is arranged inside the trough 12 and along the screw conveyor 14. .. are formed in the water distribution pipe 20 at equal intervals in the axial direction of the water distribution pipe 20. These water injection holes 22, 22 ... Are formed toward the screw blades 18 of the screw conveyor 14 as shown in FIG.

Next, the operation of the screw conveyor device 10 configured as described above will be described. As described above, the foreign matters are conveyed in the trough 12 in the direction of the arrow by rotating the rotating shaft 16 and rotating the screw blades 18. At this time, since the screw blades 18 are coated with the surface lubricant, the contaminants being conveyed do not adhere to the screw blades 18 and are contaminated by the water sprayed from the water jet holes of the water distribution pipe 20. Since the lump of the object is loosened, it is possible to prevent the foreign matter from being clogged between the screw blades 18.

With this, in the present embodiment, it is possible to prevent the foreign matters from co-rotating between the screw blades 18, so that the foreign matters can be smoothly transported as compared with the conventional screw conveyor device. Although the trough 12 is used in this embodiment, the present invention is not limited to this, and a pipe-shaped pipe material may be used.

Further, since the inner surfaces of the screw blades 18 and the trough 12 can be washed with the water sprayed from the water spray holes 22, 22, ..., The inside of the trough 12 can be kept hygienic.

[0012]

[Effect of the device]

 As described above, according to the screw conveyor device of the present invention, the screw blade is coated with the surface lubricant to prevent the foreign matters from adhering to the screw blade, and the water pipe is attached to the rotary shaft of the screw blade. Since they are arranged in parallel and the water sprayed from the water spray holes of the water distribution pipe is used to loosen the lumps of foreign substances that are blocked during transportation, the foreign substances are prevented from co-rotating and the foreign substances are smoothed. Can be transported.
