A flame preheating lance
ActiveCN224371968UImprove the problem of large differences in preheating degreesAdjust deflection anglePretreated surfacesCoatings
This application discloses a flame preheating spray gun, relating to the field of pipeline welding technology. It includes a base with a support bracket, and an air inlet pipe. The air inlet pipe has an arc-shaped nozzle mounting plate with several flame nozzles communicating with the inner cavity of the air inlet pipe. The nozzle mounting plate has mounting holes for installing the flame nozzles. The support includes a telescopic rod and a telescopic sleeve. The telescopic sleeve has a fixing rod, and the telescopic rod has several fixing holes for the fixing rod to pass through and insert into. Before preheating large pipelines, a nozzle mounting plate matching the curvature of the pipeline's outer wall is selected, and the flame nozzles are fixed at equal intervals along the extension direction of the nozzle mounting plate. By replacing multiple independent flame spray guns with flame nozzles arranged in a straight line, the problem of significant differences in preheating levels in different areas is improved.

A liftable business training conference screen bracket
ActiveCN224284127Uheight adjustableeasy to useStands/trestlesIdentification meansGear wheelElectric machinery
This application discloses a liftable business training conference screen bracket, relating to the field of display screens. It includes a base, chassis, display screen, lifting assembly, and rotating assembly. The height of the display screen is adjusted through the cooperation of a motor, threaded rod, and threaded sleeve. After adjustment to a specified height, a locking plate engages with a limiting slot by rotating it. Further adjustment of the threaded sleeve lowers the locking plate until it engages with a groove at the bottom of the limiting slot, ultimately locking the display screen height for ease of use. Rotating the rotating gear on the outer surface of the connecting shaft drives the fixed gear ring to rotate, thereby adjusting the screen's deflection angle. Pushing the sliding rod and using a compression spring to engage the insert rod on the lower surface of the pressure plate with the insertion hole locks the rotating gear on the outer surface of the sliding rod with the fixed gear ring. A limiting block further locks the fixed gear ring by driving the rotating gear on the outer surface of the sliding rod, facilitating adjustment and locking of the deflection angle.

A washing cyclone pump with a material size selection structure
ActiveCN115539398BAdjust deflection angleAdjust the flowable areaPump componentsCircumferential flow pumpsImpellerGear wheel
This invention relates to the field of vortex pump technology, specifically to a washing vortex pump with a material size selection structure. It includes an integrated plate, a motor, a connector, and a vortex pump. The vortex pump encloses a pump casing and an impeller. The pump casing is connected to an inlet pipe and an outlet pipe. The inlet pipe has an anti-backflow mechanism, and the outlet pipe has a selector body. The selector body includes an adjustment structure and an adjustment plate. The pump casing has a transmission port, and the impeller is connected to a transmission shaft and a fluid separator. In this invention, the adjustment structure allows a lever to rotate a gear ring within a groove, which in turn drives a gear rod meshing with the gear ring to rotate within a vertical groove. This, in turn, drives a screw sleeve threaded to the gear rod to rotate the adjustment plate within a side opening, thereby adjusting the deflection angle of the adjustment plate and the flow area within the outlet pipe. This allows for the targeted extraction of solid particles of different sizes from impurity fluids.
