Precipitation and filtration tank

Abstract

The invention discloses a precipitation and filtration tank, which comprises a tank body, a tank cover, a water inlet and a drainage port; a plurality of partition plates are arranged in the tank body; the plurality of partition plates partition the internal space into a plurality of precipitation tanks; waste water sequentially flows through the precipitation tanks; the waste water is precipitated in the plurality of precipitation tanks, the partition plates are gradually heightened, and the density of gypsum is higher than that of water, so the gypsum is easily precipitated; after the wastewater flows through the final precipitation tank, the gypsum in the waste water is nearly totally filtered; a wax baffle plate is arranged in the tank body; the density of wax oil in the waste water is lower than that of the water, and the wax baffle plate can intercept the wax oil floating on the water surface, so that the precipitation and filtration tank not only can precipitate and filter thegypsum mud, but also can filter the wax oil; the precipitation and filtration tank does not accidently leak water due to the design of a floating ball assembly and an overflow water hole; first and second filtration net slings are conveniently and fast assembled and disassembled, so that the clearing workload of a user is greatly lightened; and rollers are arranged at the bottom of the tank body,so that the precipitation and filtration tank is convenient to move.

Description

technical field [0001] The invention relates to a device mainly used for precipitating and filtering gypsum, in particular to a settling filter box used for treating waste water containing gypsum in dental or technical laboratories. Background technique [0002] In the daily work of dental clinics, technical laboratories and denture processing workshops, many gypsum products are used, which will generate a large amount of wastewater containing gypsum. At present, most of this wastewater is discharged directly without purification treatment, which is not only easy Blocking the sewer, and will have a negative impact on the natural environment and human health, so it is necessary to provide a device that can remove the gypsum in the gypsum wastewater and then discharge the water, so as to facilitate the smooth flow of the sewer and protect the environment and human body healthy. Wastewater from dental clinics, labs, and denture processing workshops generally contains wax oil, ...
