A kind of suction tube, suction system and powder spraying chamber;Suction tube is provided with suction inner cavity along the height extension direction;The side of suction tube is provided with multiple sections of tube suction port from low to high respectively, multiple tube suction ports are arranged in line in turn, and tube suction port is the input end of suction tube;Wherein two tube suction ports distributed in upper and lower are spaced apart to form the empty side;The side position of suction tube is provided with tube air outlet, tube air outlet is located outside the empty side, tube air outlet is horizontally aligned with the empty side, and tube air outlet is the output end of suction tube;Tube suction port, suction inner cavity and tube air outlet are communicated.This scheme can unify and quickly recycle powder of multiple height positions of powder spraying chamber, the suction volume of powder spraying chamber is smaller, power consumption is lower, and the situation that other positions are difficult to inhale powder due to excessive local air volume is prevented.

This invention belongs to the field of fiber tube forming technology, and discloses a ceramic fiber filter tube vacuum forming device and forming method. The ceramic fiber filter tube vacuum forming device includes a forming component, a tube removal component, and a material distribution component. The forming component includes a support drive component, a roller, a vacuum filtration component, and a forming roller. Two rollers are spaced apart, and the support drive component can drive the rollers to rotate. The vacuum filtration component is connected to the forming roller, and the forming roller has several filtration holes. The forming roller is located above the two rollers, and the two rollers and the forming roller are triangularly distributed. The diameter of the forming roller is adjustable. The tube removal component includes a tube removal drive component, which is connected to the forming roller and can drive the forming roller to move along its axial direction. The material distribution component is configured to rotate the forming roller and distribute slurry onto the forming roller. The forming method uses the above-mentioned ceramic fiber filter tube vacuum forming device to improve the surface quality and strength of the filter tube, while also improving production efficiency.
