Description

Technical Field

[0001] The utility model relates to the technical field of concrete production equipment, and particularly relates to a sewage filtering device. Background Technique

[0002] Concrete, abbreviated as "砼", is a general term for engineering composite materials in which aggregate is cemented into a whole by cementitious materials. Usually, the term concrete refers to cement concrete made of cement as the cementitious material, sand and stone as the aggregate; mixed with water in a certain proportion and stirred. It is also called ordinary concrete and is widely used in civil engineering. Sewage is generated during the production of concrete, so sewage needs to be treated. In order to make the sewage meet the standard for continued use after treatment, the sewage mixed with concrete often needs to pass through multiple sedimentation tanks first, so that the concrete in the sewage is gradually precipitated and separated; the sewage after multiple sedimentations is finally filtered by a filter press, and the generated clear water is stored in a clear water tank for use in cleaning the production line, and even can be used in the production of concrete after passing the detection. The following problems exist in the prior art:

[0003] Because in the existing sewage treatment methods, only the sewage mixed with concrete can be naturally sedimented and filtered, the filtering time is long, which affects the overall sewage treatment efficiency. At the same time, in the existing sewage treatment methods, the solid concrete sedimented from the sewage often precipitates at the bottom of the sedimentation tank, and can only be cleaned by equipment such as an excavator during treatment, and the treatment process is time-consuming and laborious.
