Description

  The present invention is a liquid using a multi-winding roll as a filtering means used for filtration regeneration of liquids containing impurities such as various waste liquids, for example, used cooking oils and used cleaning liquids used for cleaning floors of buildings, etc. The present invention relates to a filtration device.

As shown in Patent Document 1, conventionally, multiple winding rolls formed by multiple winding of paper filter cloths are concentrically loaded in a cylinder, and liquid is wound around the multiple winding rolls from one winding end surface of the multiple winding rolls. A liquid filtration device is known which penetrates into the layer and leads out from the other winding end surface, and introduces the liquid to be filtered into the liquid supply chamber at the cylinder end facing one winding end surface of the multiple winding roll, A configuration is adopted in which penetration of the multiple winding roll from one winding end surface into the same roll is performed.
Utility Model Registration No. 3104028

  Thus, in this conventional liquid filtering apparatus, as shown in FIG. 6, a part of the liquid 3 supplied on one winding end surface of the multi-winding roll 1 is separated from the outer peripheral surface of the multi-winding roll 1 and the cylinder. 4 passes through the interface 5 with the inner peripheral surface of the roll 1 and does not pass through the wound layer of the roll 1 and is led out from the other wound end face of the roll 1.

  Similarly, a part of the liquid 3 passes through the interface 6 between the outer peripheral surface of the winding shaft 8 existing on the core of the multiple winding roll 1 and the surface in contact with the winding shaft 8 of the multiple winding roll 1, and the winding layer of the roll 1. The phenomenon which is derived | led-out from the other winding end surface of the roll 1 without passing inside is produced.

  The above phenomenon is remarkable when the liquid 3 is pressed and infiltrated from one winding end surface of the multi-winding roll 1, and these phenomena cause a significant decrease in liquid filtration efficiency and filtration performance.

The present invention includes a liquid introduction tube as means for supplying liquid to the liquid inlet surface serving one winding end faces of the multi-turn roll, allowed comprising an outer cylinder and the inner cylinder provided concentrically with each other in the liquid introduction tube, outer The opening end of the cylinder is encircling into the winding layer of the outer peripheral portion of one winding end surface of the multiple winding roll, and the inner end of the one winding end surface around the core of the multiple winding roll The winding layer of the multi-winding roll is formed from the winding end surface between the outer cylinder and the inner cylinder, which is defined by the biting of each opening end, by causing the liquid introduced between the inner cylinder and the outer cylinder to bite into the winding layer of the section.

It is.

In addition, the present invention provides a seat plate having a claw projecting upward on the bottom surface of the cylinder, and the claw of the seat plate is placed in the winding layer of the other winding end surface of the multiple winding roll. It also uses a structure that allows it to be devised.

  In addition, the liquid introduction cylinder can be provided integrally with the sealing lid of the cylinder, and the biting state can be easily obtained simply by loading multiple winding rolls into the cylinder and closing the sealing lid.

  The multi-winding roll used as the filtering means includes a core having a winding shaft as in the conventional example and a core having no winding shaft, that is, a coreless roll, and a coreless roll. The intended purpose can be achieved by using a structure in which the liquid introduction cylinder, that is, the outer cylinder, is bitten into the wound layer on the outer peripheral portion of one winding end surface of the multiple winding roll without using the inner cylinder.

  In addition, even in the case of a coreless roll that does not have a winding shaft in the core but has a through gap in the core, a liquid leaks out of the through gap by adopting a biting structure with the outer cylinder and the inner cylinder. It can be effectively prevented by the inner cylinder.
