Sandstone filtering equipment for concrete waste water

Abstract

The invention relates to filtering equipment, in particular to sandstone filtering equipment for concrete waste water. The purpose of the invention is to provide a sandstone filtering equipment for concrete waste water with high filtering efficiency and time and labor saving. The technical scheme is that the sandstone filtering equipment for concrete waste water comprises a bottom plate, a mounting frame, a box body, a blanking pipe, an arc plate, a vertical plate, a cylindrical frame, a discharge hopper and the like; the right end of the top of the bottom plate is connected with the mountingframe; the left side of the upper part of the mounting frame is connected with the box body; the left side of the top of the box body is connected with the blanking pipe; the blanking pipe is communicated with the box body; the lower part of the left side in the box body is connected with the arc plate; and the arc plate is connected with the front and rear sides in the box body. According to thesandstone filtering equipment provided by the invention, most of the sandstones are isolated and deposited on the arc plate, and then the waste water is further filtered by a screen frame, so that thesandstones in the waste water are fully filtered; and spiral blades rotate to take the sandstones on the arc plate out of the box body, so that the filtered sandstones are collected, and an effect ofsaving time and labor is achieved.

Description

technical field [0001] The invention relates to a filtering device, in particular to a sandstone filtering device for concrete wastewater. Background technique [0002] Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete that uses cement as the cementitious material, sand and stone as the aggregate; it is mixed with water in a certain proportion and stirred. It is also called ordinary concrete, which is widely used in civil engineering. [0003] Concrete mixing stations inevitably produce a large amount of wastewater during the production and operation process. This wastewater not only contains conventional building materials such as sand, gravel, and cement. At the same time, it also contains various types of concrete additives. If it is discharged directly, it will cause serious pollution to the natural environment. There...
