3results about How to "Uniform jet" patented technology

The application discloses an abrasive water jet generation system, and belongs to the technical field of abrasive water jet. The system comprises a jet generation main body integrated on a tracked walking chassis, a vibrating screen module, a cyclone separation module and a sewage sedimentation tank. The jet generation main body forms a strong cyclone by a water injection pump to a sand mixer circumferential tangential water inlet, and combines the design of a mixing plate on the inner wall to make the abrasive and water fully and uniformly mixed, and then a discharge pump and a booster pump output stable jet. The system also screens, cyclone separates and deposits the used abrasive-containing wastewater and rocks, realizes the recycling and recycling of the abrasive and water. The application effectively improves the abrasive mixing uniformity and jet quality, and significantly reduces the consumption of water and abrasive through closed-loop recycling, and is suitable for mobile high-efficiency rock breaking operation in mine, tunnel and other scenes.

The utility model relates to the technical field of cutting torch equipment, and improves the operation safety of a cutting torch device in the prior art. The cutting torch device comprises a gas inlet pipe assembly which is configured to be connected with an external gas source and convey combustible gas and combustion-supporting gas; the mixed gas chamber is connected with the gas inlet pipe assembly and is used for realizing gas premixing and pressure balance; one end of the jet pipe assembly is connected with the outlet end of the mixed gas chamber, and a nozzle is formed in the other end and used for accelerating flowing of the mixed gas and forming stable jet flow; the one-way valve is arranged on the jet pipe assembly and used for preventing gas from flowing reversely and maintaining the system pressure stable; and the fire arresting piece is arranged on the air inlet pipe assembly and the jet pipe assembly and used for preventing flame burn-back. The device is high in integration level, forms a multiple safety protection mechanism, and remarkably reduces the operation risk.

The large-evaporation-capacity low-pressure spray head comprises a flow channel pipe and a spray nozzle which are communicated, the flow channel pipe is provided with a first limiting body, a second limiting body and a swing body, the swing body is movably installed between the first limiting body and the second limiting body, and the swing body is connected with a water dispersing disc. The water dispersing disc is provided with a water dispersing needle located in the center and a plurality of flow channels arranged in the circumferential direction of the water dispersing needle, the flow channels rotationally extend from the water dispersing needle to the edge of the water dispersing disc, and water dispersing rib plates extending into the flow channels in the axial direction of the flow channels are arranged in the centers of the flow channels close to the edge of the water dispersing disc. The spray nozzle is used for jetting water to the water dispersing needle and driving the water dispersing disc to swing up and down and circumferentially around the spray nozzle along with the swing body, the spray nozzle can give consideration to the jetting range and the stable operation characteristic under the low-pressure working condition, the atomization evaporation capacity and the combination uniformity of the spray nozzle are effectively improved, the evaporation rate can reach 16% or above, and the Crisqin uniformity can reach 90% or above. The swinging body is detachably connected with the water dispersing disc, dismounting and replacement are easy, and the requirements for waste liquid recovery and cost saving of modern industries such as the mining industry are met.
