A sludge cleaning device for water conservancy and ecological environment protection, comprising a hull and a swirl column, the other end of the swirl column is fixedly connected with a negative pressure column, the side wall of the swirl column is fixedly connected with a feed pipe, and one end of the feed pipe is rotatably connected There is a diversion pipe, the bottom of the diversion pipe is connected with a dredging column, the dredging column is fixedly connected with a first motor, the output end of the first motor is fixedly connected with a drive shaft, one end of the drive shaft is fixedly connected with a spiral plate, and the drive shaft The other end is fixedly connected to the propeller; the worm drives the dredging column to rotate through the rocker mechanism; the negative pressure column is fixedly connected to the spray pipe, the top of the spray pipe is provided with a spray assembly for irrigation, and the positioning shaft is provided with a device for adjusting the rotation angle of the diversion pipe. The adjustment assembly; the invention not only reduces the difficulty of dredging, but also further ensures the high efficiency, rationality and accuracy of sludge cleaning.

The present invention relates to the field of 3D printers, more specifically an anti-blocking nozzle for a continuous carbon fiber 3D printer, including an anti-blocking operating seat, a continuous adder, a heating nozzle, a regulator and a combined anti-blocking dredge, the continuous adder Fixedly connected and connected to the anti-blocking operation seat, the heating nozzle is connected and connected to the lower end of the anti-blocking operation seat through thread fit, the regulator is rotatably connected in the anti-blocking operation seat, and the combined anti-blocking dredger is clearance fit in the regulator, The combined anti-blocking dredger is longitudinally slidably connected to the anti-blocking operating seat; the beneficial effect of the present invention is that it can effectively dredge the printer nozzle pipeline blocked by the melted raw material; through manual adjustment, the dredging effect can be stably ensured while avoiding damage to the nozzle. Affect the service life; easy to operate, fast dredging.

The invention discloses a pipeline dredging device. Through the device, one end of a carbon gun of a carbon powder pipeline is clamped, a ball valve is opened to input compressed air into the carbon powder pipeline, after a pressure gage displays that the pressure rises to the system pressure, the ball valve is closed, a pressing rod is pressed, pressure in the pipeline ejects an end cover open, carbon powder is brought out of the pipeline, the end cover is closed, the ball valve is opened, the compressed air is input again, and through repeated implementation of the above steps, the pipeline can be successfully dredged; through the device, the positive and negative pressure difference alternative dredging of any connecting point of the pipeline can be achieved, rapid loading and unloading and the carbon powder pipeline dredging work can be completed only through one person, the dredging efficiency and the success rate are improved, the shutdown overhauling time is shortened, the dredging effect and quality are ensured, involved parts are common spare parts in equipment management, the cost is low, material taking is convenient, mounting is convenient, detection is reliable, and maintaining is easy.

The invention relates to the technical field of concrete filling, in particular to a concrete filling device with an anti-blocking structure. The concrete filling device with the anti-blocking structure comprises a filling device main body, the filling device main body comprises a filling hose, one end of the surface of the filling hose is sleeved with a first fixed support plate, folding support frames are arranged on both sides of the first fixed support plate, and one end of the surface of the filling hose is sleeved with a vibration mechanism. A user can well guarantee the discharging speed during material discharging through the filling device main body, the user can conveniently control the hose, through the vibration mechanism, a spring vibration piece is stressed and vibrates in poured concrete, part of air bubbles doped in the concrete during pouring are well vibrated and removed when the concrete is filled, after a building is completed, a user pulls the filling hose, a pedal rubs a concrete pouring surface, and the concrete surface is quickly plastered to be flat.

A method for preparing a diffusion layer for a fuel cell, comprising the following steps: taking mature corn stalks, removing the outer skin of the corn stalks, taking the straw material at the soft center of the corn stalk, and then drying the straw material; Long strips, and then placed in a polar solvent to form a polar solution, fully stirred and mixed; adding ceramic particles and carbon oxide materials to the polar solution and fully stirred; then beating papermaking, impregnating resin, and carbonizing in sequence, Finally, a diffusion layer is obtained. In this application, the material in the center of corn stalks is used as a fibrous material, and then mixed with ceramic particles and carbon oxide materials under the action of a polar solution. The ceramic particles have a certain hydrophobicity and the ability to expand pores, ensuring this The dredging ability of the bit diffusion layer, and the use of carbon oxide materials is to increase its combination with the straw material and form a carbon skeleton.

The invention discloses a peristaltic urban pipeline dredging robot, which adopts a segmented structure and includes a reamer cabin and a walking cabin, and the reamer cabin and the walking cabin are connected by several sets of tension springs. The cutter cabin includes a transmission shaft, a reamer cabin casing, an inner cavity of the reamer cabin, several guide wheels, an inner reamer, an outer reamer and a first motor, and the walking cabin includes a running cabin casing, a running mechanism and a fixed rod. The present invention achieves the purpose of continuous pipeline dredging work through the synergistic action of the traveling mechanism, the inner reamer and the outer reamer, and can cope with the dredging in the pipeline through the collection of umbrella-shaped shielding rings and the crushing and collection of the inner and outer reamer. Due to the complex environment and the filled walking mode of the peristaltic robot, the dredging effect is guaranteed, the dredging efficiency is improved, and the energy consumption of dredging is reduced, and finally it can replace the backward dredging methods such as manual dredging and high-pressure water jet. the goal of.
