Solid-liquid separation device and garbage disposer

Abstract

Provided is a solid-liquid separation device maintaining sealing performance to prevent discharge of a mixture of water and garbage from a sliding contact part between the side surface of a strainer and the inner wall surface of a separation container even if the solid-liquid separation device is used for a long time, and accurately separating solid and liquid. The solid-liquid separation device includes a separation container 12 for introducing garbage together with water, a strainer 14 rotationally driven in the separation container 12, a scraper for separating garbage from water in cooperation with the strainer 14. In the solid-liquid separation device, the strainer 14 is composed by superposing multiple number of ring bodies 14b including flat ring portions 142 each formed with projections 141 on the outer peripheral surface, in a spaced manner to strain out the garbage, and sliding members 70a and 70b for preventing abrasion of the inner wall surfaces of the separation container portions 12a and 12b are attached to parts of the inner wall of the separation container 12 with which the ring portions 142 of the strainer 14 make sliding contact, in the circumferential direction of the ring portion 142.

Description

technical field [0001] The present invention relates to a solid-liquid separation device for separating domestic waste (solid matter) from water, and a domestic waste treatment device using the solid-liquid separation device. Background technique [0002] In the prior art, various methods of disposing of household waste generated in kitchens and the like have been proposed. As a domestic waste treatment device installed and used at the sink of the kitchen, the applicant once proposed a device with the following structure, that is, a crusher for crushing domestic waste is installed at the drain of the sink in the kitchen. The domestic garbage broken by the machine is guided into the solid-liquid separation device together with water, and the domestic garbage (water-containing garbage) separated from the water phase by the solid-liquid separation device is dried by the drying device, and treated as waste (refer to patent documents 1, 2, 3).

AI Technical Summary

Problems solved by technology

[0013] However, the separation container 12 is a resin molded product, while the filter 14 is made of stainless steel. If the solid-liquid separation device is used for a long time, the side surface of the filter 14 and the inner surface of the separation container 12 will be worn and separated. The gap between the inner wall surface of the container 12 and the side surface of the filter 14 (the side surface at the outermost position) is enlarged, and there is a possibility that a mixture of water and household waste is discharged from the gap part.
