2results about How to "Avoid cleaning dead ends" patented technology

This utility model discloses an anti-fouling membrane wastewater treatment device, belonging to the field of wastewater treatment equipment technology. It includes: a wastewater treatment component for filtering wastewater; a cleaning agent transmission mechanism for outputting cleaning agent and driving multiple sets of rotating cleaning components to revolve; and multiple sets of evenly distributed rotating cleaning components. Each set of rotating cleaning components includes a branch pipe fixedly installed through the outside of a rotating pipe. A hollow turntable is rotatably connected to the outer end of the branch pipe away from the rotating pipe via a bearing. Multiple cleaning holes are evenly distributed on the side of the hollow turntable away from the branch pipe. This utility model avoids cleaning dead zones caused by gaps between adjacent nozzles, resulting in better actual cleaning performance and effectively reducing impurity residue. Furthermore, it utilizes only the driving force of the cleaning liquid spraying out, eliminating the need for additional driving components.

This invention relates to the field of cable testing technology, specifically a cable connection testing device for flame-retardant cable installation, comprising: a base plate; a positioning and guiding mechanism, wherein the positioning and guiding mechanism for positioning and guiding the cable under testing is disposed at the top of the base plate; a testing mechanism, wherein the testing mechanism for testing the surface flatness of the cable is disposed at the top center of the base plate; and a cleaning mechanism; the guiding component in the positioning and guiding mechanism of this device can be freely adjusted according to the cable specifications, enabling better guidance of the cable, while the positioning component can center the cable, ensuring that the cable is in a centered state during testing, thus improving the accuracy of testing; under the action of the transmission component, the cleaning component can rotate synchronously with the guiding component, allowing the cleaning block to rotate and clean, preventing dust and impurities on the cable surface from affecting the testing of the cable surface flatness.
