The invention discloses a latex powder spray drying tower, the lower end of the elastic sheet is provided with a vibration sheet, the vibration sheet is fixedly connected with the tower body, the air outlet of the inclined high-pressure nozzle is aligned with the vibration sheet, and the other side of the inner wall of the cavity is opened The hole is provided with a first high-pressure nozzle, the first high-pressure nozzle is covered with a second filter cover, and the side wall of the second filter cover is provided with a second round hole, the lower end of the vibrating piece contacts the movable part of the vibration-type leakage structure, and the outer wall of the tower body A side plate is provided, and a control box is placed next to the side plate, and the humidity detection head is fixedly connected to the side plate; a latex powder spray drying tower of the present invention belongs to the field of latex powder drying towers, and adopts a high-pressure sprayed intermittently by an inclined high-pressure nozzle. The spray drives the vibrating sheet to vibrate, and the vibrating sheet drives the vibrating leaking material structure to vibrate, so as to realize the flying of latex powder at the vibrating leaking structure, realize the mixing of latex powder and high-pressure spray, speed up the drying process of latex powder, and ensure the latex powder The drying degree reaches the production standard.
