4results about How to "Guaranteed drainage efficiency" patented technology

The application relates to the technical field of tunnel construction, and discloses a tunnel construction drainage device, which solves the problem that the cleaning mechanism of the existing drainage device has a complex structure, the complex matching structure is prone to faults in operation, and the cleaning of the silt is ineffective; the water flow drives the rotary drum to rotate, thereby providing power for the rotation of the filter cover; the driving mode has a circulating operation path, has no redundant components or complex interaction, has a low failure rate, is convenient for long-term stable operation in a complex underwater environment, the rotating filter cover and the non-porous part of the surface cooperate with the inclined shelf to work, the silt adsorbed on the surface of the filter cover is continuously cleaned, the filter cover keeps the water filtering efficiency, the suction assembly enables the suction cover to generate suction force to suck the cleaned silt, the silt is prevented from being active near the filter cover, and the workload of the inclined shelf for cleaning the silt is increased; the movement path of the above structure is circular, the operation process is orderly, the regularity is high, and the drainage operation is suitable for stable operation in a complex underwater environment.

The utility model discloses a highway foam light soil roadbed widening's waterproof and drainage structure belongs to highway technical field, including concrete foundation, one side of concrete foundation is provided with support step, another side fixed connection of concrete foundation has prefabricated panel. In the utility model, through setting up first water slope at the top of support step top, setting up second water slope at the top of support step side, when water enters the top of support step, utilize first water slope and flow to the water in macadam blind ditch, so that make water enter longitudinal soft type water -permeable pipe, utilize second water slope and flow to the step groove in water simultaneously, water enters transverse turning water -permeable pipe, so that make water from longitudinal soft type water -permeable pipe, transverse turning water -permeable pipe and transverse soft type water -permeable pipe fast discharge, guarantee the efficiency of drainage, and good practicality.

The invention discloses a slag water treatment system in a pulverized coal gasification process, and relates to the field of slag water treatment.The slag water treatment system comprises an external supporting cylinder, the inner wall of the external supporting cylinder is fixedly connected with a bottom plate, the two sides of the top wall of the bottom plate are fixedly connected with vertical plates, and the tops of the vertical plates are rotationally connected with a filter barrel; the bottom of the filter barrel is rotatably connected with a stirring shaft through a shaft sleeve, the outer wall of the stirring shaft is fixedly connected with stirring blades, and the bottom wall of the bottom plate is fixedly connected with a motor. The motor is started to drive the driving shaft to rotate, and then the stirring shaft is driven to rotate synchronously, so that stirring blades rotate to turn over slag in the filter barrel, liquid in the filter barrel can be leaked out more quickly through leakage holes in the filter barrel, and meanwhile, in the rotating process of the driving shaft, the slag in the filter barrel can be filtered out more conveniently. The universal driving shaft is driven to rotate under the transmission action of the bevel gear set, meanwhile, the filter barrel is driven to rotate through the extension block, liquid in the filter barrel is discharged more quickly by means of centrifugal force in the rotating process of the filter barrel, and the liquid discharging efficiency is guaranteed.

This application relates to a multi-hole parallel-arranged culvert, belonging to the technical field of culvert construction. It includes a culvert body with multiple parallel-arranged water passages; and a filtration mechanism. The filtration mechanism includes a mounting bracket located outside the water passages, a filter end cap slidably mounted on the mounting bracket and corresponding to each water passage, a drive assembly mounted on the mounting bracket for sliding the filter end caps, and a sludge storage tank mounted on the mounting bracket and located below the outlet of each water passage. The filter end cap has filter mesh openings for covering the outlet of the water passage, and is connected to a filter scraper extending into the water passage and abutting the bottom surface of the water passage. The filter scraper has discharge holes penetrating both the upper and lower surfaces. This application effectively reduces sludge and impurities discharged from the culvert into the river channel.
