Description

Technical Field

[0001] The present application relates to the technical field of water treatment equipment, and in particular to an anti-clogging device for a micro-sand cyclone in an ACTIFLO water treatment process. Background Art

[0002] At present, the ACTIFLO water treatment process is widely used in domestic water treatment systems, especially in power plant water treatment systems. In the existing ACTIFLO water treatment process, there is no filtering device between the mud containing micro-sand at the bottom of the sedimentation tank and the micro-sand cyclone through the sand pump. Although the ACTIFLO water treatment process has chlorination equipment, when the process is applied to the seawater pretreatment system, due to the breeding of marine organisms, the number of shells in the sedimentation tank and the micro-sand cyclone pipeline increases, resulting in impurities directly entering the micro-sand cyclone, causing the micro-sand cyclone to frequently clog. Utility Model Content

[0003] In order to solve the above technical problems or at least partially solve the above technical problems, the present application provides an ACTIFLO water treatment process micro-sand cyclone anti-clogging device, which aims to solve the problem of micro-sand cyclone pipeline blockage.

[0004] An embodiment of the present application provides an anti-clogging device for a micro-sand cyclone in an ACTIFLO water treatment process, comprising: a shell, an isolation portion and a filter screen; wherein the shell forms a accommodating chamber having a medium inlet and a medium outlet, the medium outlet is connected to the micro-sand cyclone, and the shell has a sewage outlet; the isolation portion is arranged in the accommodating chamber near the medium inlet, and the isolation body and the sealing member cooperate to form the isolation portion; the isolation body has a through hole connecting the medium inlet and the accommodating chamber, and the sealing member coincides with the through hole when closed; the filter screen extends along the through hole to the sewage outlet to form a filter chamber, one port of the filter chamber is connected to the through hole and the other port is connected to the sewage outlet.

[0005] In some embodiments, the anti-clogging device further includes an observation portion, which is disposed on a surface of the housing and is used to observe the flow and state of the medium inside the filter cavity.

[0006] In some embodiments, the size of the through hole is equal to the size of the sealing member, and the shape of the through hole is the same as the shape of the sealing member.

[0007] In some embodiments, the mesh of the filter is a circular hole, and the diameter of the circular hole is 1 cm.

[0008] In some embodiments, the anti-blocking device further comprises a switch, wherein the switch is connected to the sealing member and is used to open or close the isolation portion.
