Description

Waste liquid pretreatment device Technical Field The utility model relates to the technical field of medical instruments, in particular to a waste liquid pretreatment device. Background The nursing waste liquid pretreatment device is waste liquid treatment equipment used in hospitals, nursing homes and other places. It can carry out preliminary treatment to nursing waste liquid, for example, get rid of solid, granule, foreign matter, impurity, bacterium etc. in the nursing waste liquid, reduces the concentration and the pollution degree of waste liquid to reduce the pollution and the sanitary safe risk of nursing waste liquid to the environment. When the existing nursing waste liquid pretreatment device is used for pretreatment of waste liquid, solid-liquid separation is mainly carried out in a filtering mode. But the filtered solid waste is filtered out and then accumulated above the filter screen, and the filter holes on the filter screen are blocked, so that the solid waste on the filter screen needs to be removed in time, and the waste liquid pretreatment device can work normally. Currently, the cleaning mode for cleaning the solid garbage accumulated on the filter screen is mainly to manually remove the solid garbage from the filter screen, for example, to manually grab the solid garbage away. Because solid garbage is harmful to human body, protective gloves are also needed when the solid garbage is manually cleaned. The operation mode not only needs to be participated in manually, thereby increasing extra labor cost and time cost, but also has low working efficiency and reduces the pretreatment efficiency of nursing waste liquid. The personnel who carry out the cleaning have a safety risk of being infected with solid waste.
