Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of solid-liquid separation equipment, in particular to waste solid-liquid separation equipment used for environmental protection. Background Art
[0002] In the process of environmental protection, rivers are often dredged. In the process of dredging, solid-liquid separation operations are required. Usually, an inclined screen separator is used for solid-liquid separation. When the separator is in use, the extracted material will flow down from the top of the machine, and a large amount of sewage will be separated when flowing down from the inclined screen. Although the subsequent extracted material will impact the previous material and flush it into the auger, the auger spirally squeezes the separated solids and discharges them at the end, but there will still be residues on the screen, causing blockage of the screen and reducing the filtration efficiency. Therefore, the existing device adds a brush or scraper to assist in cleaning.
[0003] However, in order to ensure the falling of the material, a vibration device is usually installed on the installation frame of the screen to vibrate the material and assist the falling. Therefore, when the brush or scraper is scraping, intermittent gaps will appear between the screen, making it impossible to fit the screen and clean the material. At the same time, when the brush or scraper fits the screen, it will squeeze the material and squeeze it into the holes of the screen, causing the screen to be blocked. Utility Model Content
