Hereinafter, a morphological example of the object feed device for the separator according to the present invention will be described in detail with reference to the accompanying drawings (FIGS. 1 to 6).

The centrifuge feeding device of the present embodiment uses a liquid to be separated, for example, a liquid-containing material and a resin sheet-like material having a high liquid content such as a used diaper having a high water content. The liquid can be sequentially fed to the separator 10 which separates the contained substance and the resin sheet-like substance by using centrifugal force by the operation of the screw 40 without separating the liquid as much as possible before the liquid is put into the separator 10. be.

Reference numeral 20 denotes a supply passage portion, which is provided so as to form a passage extending horizontally so that the material to be separated can be supplied to the separator 10 and to insert the screw 40. It includes an upper surface opening connection portion 21 that can be connected to the supply hopper, and a cylindrical connection pipe portion 30 that is connected to the insertion port 11 into which the object to be separated of the separator 10 is inserted. That is, the supply passage portion 20 includes an upstream passage provided with an upper surface opening connection portion 21 on the upstream side to which the object to be separated is sent so as to form a screw conveyor-like supply device (feed device). On the downstream side where the object to be separated is continuously sent to the passage on the upstream side, a cylindrical downstream passage provided by the connecting pipe portion 30 is provided.

Reference numeral 33 denotes a linear guide convex portion, which is provided at a plurality of locations on the connecting pipe portion 30 at intervals in the circumferential direction so as to be convex at a height that does not interfere with the screw 40 from the inner peripheral surface 32. Along with this, it is provided so as to extend linearly in the axial direction and to guide the feed of the object to be separated. In the example of the present embodiment, the linear guide convex portion 33 is provided in a continuous shape over the entire length in the extension direction of the axis of the connecting pipe portion 30, but the present invention is not limited to this. As long as it extends in the extension direction of the axis of the connecting pipe portion 30, the connecting pipe portion 30 may be partially provided instead of the total length, or may be provided intermittently. Further, when it is provided intermittently, the number of the linear guide protrusions 33 may be different between the upstream and the downstream where the object to be separated is sent.

According to the linear guide convex portion 33, the pressure applied to the object to be separated generated by the rotation of the screw 40 about the axial center is appropriately converted into the pressure of the motion sent in the axial extension direction of the screw 40. be able to. Therefore, according to the object feed device for the separator of the present invention, the object to be separated including the liquid-containing substance and the resin sheet-like substance can be appropriately separated by the centrifugal force. In addition, it has a special advantageous effect that it can be put into the separator more appropriately.

Further, according to the example of the present embodiment, specifically, the used diaper having a high water content, which is an example of the object to be separated, is more appropriately transferred to the separator 10 so that the separation effect by the centrifugal force can be appropriately obtained. It has a device configuration that can be turned on. That is, for example, when a used disposable paper diaper is sent to the separator 10 by the object feeding device for the separator of this embodiment, the diaper is made of a non-permeable resin sheet and water permeable provided in the form of a filter. A resin sheet-like material having a property is likely to stick to the inner peripheral surface 32 of the connecting pipe portion 30 and easily rotate together with the screw 40, but the linear guide convex portion 33 acts as a resistance and the resin sheet. It acts to prevent the object from rotating together. Then, by the action of the linear guide convex portion 33, the direction of the force acting on the used diaper can be appropriately changed so as to be appropriately guided in the feeding direction, and the diaper can be smoothly fed. The resin sheet-like material is not limited to the constituents of the diaper, and of course, the resin sheet-like material also includes a resin bag formed in a bag shape by a sheet-like or film-like material.

Further, in this embodiment, the pitch of the spiral blades 42 of the screw 40 gradually narrows from the side of the upper surface opening connection portion 21 of the supply passage portion 20 toward the outlet 31 side of the object to be separated of the connection pipe portion 30. It is provided as follows. Note that the pitch is gradually narrowed when the pitch is continuously narrowed and when the block on the downstream side is intermittently narrower than the upstream part as a block in the required range. Of course, it means to include the case of becoming.

According to this embodiment, for example, a material to be separated containing a liquid-containing material such as a used disposable disposable diaper having a high water content and a resin sheet-like material can be appropriately separated by centrifugal force. As described above, it is compactly formed so that it can be more appropriately charged into the separator without being separated from the liquid before being charged into the separator 10 and the length can be shortened in the extension direction of the axis of the connecting pipe portion 30. It has a special advantageous effect of being able to do it.

That is, according to the example of this embodiment, the portion of the screw blade (spiral blade 42) arranged in the connecting pipe portion 30 of the screw 40 and provided with a narrow pitch acts like a packing and only liquid (for example, water) is released. It is possible to prevent the flow from being separated. That is, the pitch of the spiral blades 42 of the screw 40 is gradually narrowed, so that the object to be separated is compressed, but the portion of the spiral blades 42 having a narrow pitch becomes an appropriate resistance, so that the liquid is liquid. It is possible to stop the outflow of the material, and by applying an appropriate pressure to the object to be separated, it is possible to sequentially and stably feed the material at a constant speed. In the case where the connecting pipe portion 30 can be set sufficiently long, a sufficient pitch of the spiral blades 42 is arranged in the connecting pipe portion 30, and an appropriate resistance that prevents liquid from leaking is provided. Therefore, it may not be necessary to gradually narrow the pitch of the spiral blades 42 as in the example of the present embodiment.

Further, in this embodiment, the linear guide convex portions 33 are provided at eight positions on the inner peripheral surface 32 at eight positions equally divided around the circumference. According to this, it acts as a resistance to the object to be sent in a well-balanced manner, and the object to be separated can be sequentially and stably sent to the separator in a well-balanced manner. Since the pitch of the spiral blades 42 of the screw 40 is gradually narrowed, the object to be separated is compressed, but the pressure can be appropriately received by the linear guide convex portion 33 and fed. It can be converted into the motion of, and the object to be separated can be sent properly.

The number of the linear guide convex portions 33 and the positional relationship of the arrangement are not limited to the example of this embodiment, and are appropriately selectively selected depending on the difference in conditions such as the type of the object to be separated and the size of the device. Of course, it can be set.

Further, in this embodiment, the height of the linear guide convex portion 33 is provided to be smaller than half of the distance between the inner peripheral surface 32 and the screw 40. According to this, the clearance between the inner peripheral surface 32 and the screw 40 can be set to an appropriate length (dimension) that does not interfere even when the cantilevered bearing / supported screw 40 is bent.

Further, as shown in FIG. 6, the linear guide convex portion 33 of the present embodiment is provided with a chevron-shaped cross section so as to have an appropriate resistance to the movement of the object to be separated. In its manufacture, for example, a square bar may be fixed by welding on both sides along its longitudinal direction so that its cross section has a symmetrical trapezoidal shape with an upper base shorter than the lower base. can.

Further, the screw 40 of this embodiment is provided by welding a spiral blade 42 to the screw shaft 41, and the drive device unit 50 is formed by an electric motor, a speed reducer unit, and a power transmission unit using a chain or the like. It is configured and is provided so that the screw 40 can be rotated at an appropriate speed.

The morphological examples described above can be effectively used when the object to be separated is a used diaper using a water-absorbent polymer, but the present invention is not limited thereto, for example. Of course, it can be appropriately applied to other liquid-containing substances and objects to be separated including resin sheet-like substances such as foods packaged with a resin packaging material.

Although various examples of the present invention have been described above, the present invention is not limited to the examples of the present invention, and it goes without saying that many modifications can be made without departing from the spirit of the invention. That is.
