Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment devices for concrete preparation, in particular to a sewage treatment device for concrete preparation. Background Art

[0002] Concrete, abbreviated as "concrete", is a general term for engineering composite materials that are cemented into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates; mixed with water (which may contain admixtures and additives) in a certain proportion, and then mixed to obtain cement concrete, also known as ordinary concrete, which is widely used in civil engineering;

[0003] For example, Patent No. 202010694567.9 discloses a sewage treatment device for concrete preparation, whose structure includes: a device body, a water inlet pipe, which is connected to the inside of the device body, a rotating shaft, which is rotatably arranged inside the water inlet pipe, on which an axial flow component and a dispersion member rotatably sleeved for spirally dispersing sewage are fixedly installed, and the dispersion member is fixedly installed inside the water inlet pipe, and a filter member is slidably arranged inside the device body left and right, and is tilted, wherein a matching groove is fixedly installed on the filter member, and an eccentric wheel for driving the matching groove to swing back and forth left and right is fixedly installed at the bottom of the rotating shaft, and the eccentric wheel is in contact with the matching groove on the matching groove; the filter The filter element is elastically arranged on the left and right sides inside the device body. The utility model is added to the device body through the water inlet pipe. Under the impetus of the kinetic energy of the sewage, the axial flow component drives the rotating shaft to rotate, and then the eccentric wheel at the bottom of the rotating shaft drives the filter element to swing back and forth, thereby accelerating the filtration of sewage from the filter element. At the same time, the filtered garbage is discharged in time on the reciprocating filter element to prevent the filter element from being blocked. At the same time, a dispersion element is arranged inside the water inlet pipe to perform spiral dispersion on the sewage to be treated, thereby avoiding the sewage from directly impacting the filter element. The spiral dispersion reduces the impact force on the filter element, increases the service life of the filter element, and at the same time disperses the sewage to improve the filtering effect.

[0004] Therefore, when the above-mentioned sewage treatment device is filtering, filtering the concrete for a long time will result in a relatively short service life of the filter, resulting in an increase in the cost of sewage treatment, and the filter is not easy to replace, resulting in a waste of time when replacing the filter. A filter that is easy to disassemble and replace can be designed to improve subsequent use efficiency. Utility Model Content
