It is widely used for filtration, wet process cement slurry, starch, asbestos, paper pulp dewatering, etc. The filter medium for this type of rotary filter consists of a drum with a cylindrical shell made of wood or metal and a filter cloth, and its structure is such that the outer circumferential surface is divided into solitary chambers, and the surface of the solitary chamber lattice is used for filtering. It is wrapped in cloth or fine wire mesh, and if necessary, wire is wound spirally on top of it. Furthermore, each solitary chamber functions as an independent filter, and several suction tubes extend from each chamber toward the axis of the cylindrical drum.

る必要があり、準備に手間を要するものである。(Embodiment of the invention) In the solid-liquid separator according to this invention, the properties of the filter medium are limited to hard ones, thereby eliminating the drawbacks of conventional solid-liquid separators. That is, a conventional solid-liquid separator using a porous body uses a soft porous body, such as a belt-like one, as a filter medium, and removes the liquid component by means of squeezing or pressing.
Since it is of the type that separates the solid content contained, the apparatus is extremely large-scale and inefficient, and it has been difficult to obtain a compact and highly efficient apparatus. In addition, when a soft filter medium is used in a device of the type that removes liquid by using differential pressure as in this invention, a perforated cylindrical frame made of metal or plastic is used as the core, and the filter medium is placed around the outer periphery of the cylindrical frame made of metal or plastic. It needs to be rolled in layers, and preparation is time-consuming.

されない。 However, when using a hard material as in this invention, for example, if one uses an integrally molded material, there is no need for a core, and it can be attached and taken off as is, and when creating a filter material, there is no need for the complexity of winding layers and pasting. It is possible to omit. Furthermore, in the case of soft filter media,
There are also problems related to dimensional stability such as deformation and blinding due to suction during use, and it is not sufficient to scrape off the layered buildup that forms on the surface of the filter medium.
Therefore, it cannot withstand continuous operation for a long period of time, but if a hard filter medium is used as in this invention, this problem can be completely solved. Furthermore, there is less damage to the material itself, and the period of use can be significantly extended. The hard porous body with continuous pores referred to here may be a honeycomb-like structure having countless pores linearly continuous from the outer layer to the inner layer, but it may also be a three-dimensional network structure. It is more preferable that the pores have a structural organization and each pore is irregularly continuous. The material may be porous ceramic, sintered metal porous body, metal wire mesh laminate, sintered resin porous body, hard resin porous body, or fibrous porous body made of laminated nonwoven fabric or yarn. It may be a material treated with a thermosetting resin and cured, but a hard resin porous material is particularly suitable from the viewpoint of ease of controlling the pore diameter, light weight, etc. Examples of hard resin porous bodies include cured urethane resins, porous polyvinyl formal resins treated with thermosetting resins, and porous thermosetting resins. , there are no particular limitations.

4A is wound, and the motor 12 is connected to the deceleration mechanism 13. The cylindrical filter medium 1 is the stock solution tank 7
The undiluted solution 31 is discharged and sprayed onto the surface of the filter medium 1 from the liquid dispersion hole 30 of the long pipe, and the undiluted solution 31 that has not been sucked is placed in the undiluted solution tank 7. It is beginning to be received within the country. On the opposite side of the filter medium 1, a scraper 17 is provided as a scraping means for scraping off the solid content 18 formed in a cake shape on the surface of the filter medium 1.
is provided so that its tip is in pressure contact with the surface of the filter medium 1 via a spring 20, and a container 19 is installed below the scraper 17 to receive the scraped solids. In addition, a suction pump 15 is connected to the end of the hollow rotating shaft 4 via a pipe 16.
