Filler cleaning device suitable for constructed wetland

Abstract

The invention relates to the technical field of environmental engineering, and discloses a constructed wetland filler cleaning device which comprises a first connecting cylinder, a first fixing box is fixedly mounted at the top end of the first connecting cylinder, and a feeding cylinder and a discharging cylinder are fixedly mounted on the two sides of the first connecting cylinder correspondingly; a first water suction pump is connected to the interior of the feeding cylinder through a pipeline, and a second water suction pump is connected to the interior of the discharging cylinder through a pipeline. When a first threaded column rotates, a first connecting plate is driven to move through a first moving block, the first connecting plate drives a first inclined block to adjust the distance between the first connecting plate and a second inclined block through a second connecting column, and the throughput during filler feeding can be adjusted through the distance between the first inclined block and the second inclined block; and the filler is prevented from being blocked during cleaning.

Description

technical field [0001] The invention relates to the technical field of environmental engineering, in particular to a device for cleaning fillers in constructed wetlands. Background technique [0002] Constructed wetlands are artificially constructed and controlled grounds similar to swamps. Sewage and sludge are distributed on the artificially constructed wetlands in a controlled manner. In the process of flowing in a certain direction, sewage and sludge are mainly used. It is a technology for the treatment of sewage and sludge by the triple synergy of physics, chemistry and biology of soil, artificial medium, plants and microorganisms. The filler is the substrate and carrier of the constructed wetland, which supports the life process of the animals, plants and microorganisms in the constructed wetland. The successful retention of pollutants by the filler creates good conditions for subsequent plant absorption, and is an important guarantee for the effluent quality. [0003...

Problems solved by technology

[0003] After retrieval, Chinese Patent No. CN112827871A discloses a filler cleaning device for artificial wetlands and its use method, including a shell and a cleaning box. The top of the inner cavity of the shell is fixedly connected to the cleaning box. A first rotating rod and a second rotating rod are connected, and the first rotating rod and the second rotating rod are connected to an external drive mechanism, and several groups of cleaning brushes are arranged on the first rotating rod and the second rotating rod, and the cleaning box One side of the cleaning box is provided with a feed hopper, the right side of the cleaning box is connected to the water inlet of the water pump through the outlet pipe, the bottom end of the right side of the cleaning box is provided with a drain pipe, and the bottom of the cleaning box is located inside the housing. The cavity is provided with a processing box, and the cleaning box is flexibly connected with the processing box through the first discharge pipe and the second discharge pipe. The bottom of the processing box is provided with a discharge port, and a collection box is provided below the discharge port. , the collection box is located at the bottom of the inner cavity of the shell to realize the cleaning, disinfection and drying of the packing, but this device is cumbersome to use, and the packing needs to be fed into the shell through the feeding port on the top of the shell for stirring Cleaning, and then enter the processing box through the discharge pipe, and then collect, the process is more, and it is cumbersome and inflexible to use
