2. The hydraulic headbox (hydraulic full-flow air-cushion combined headbox) is suitable for paper machine with a speed of 350-1500m/min and a speed of 1760-5500. The tube bundle enters the pulp stabilization chamber, and there is an attenuation chamber above the pulp stabilization chamber. It has an air cushion and spray device to eliminate air bubbles and reduce pressure pulses, and has an overflow outlet. The isobaric slurry flows from the stabilization chamber through the turbulence generator. Arrive at the upper weir plate of the convergence channel.
3. Air Cushion type headbox can increase the sizing pressure to meet the requirements of medium and high speed paper machines. The headbox consists of square taper tube device, evener roll device, top lip plate adjusting device, box body,control system, spraying device, air path system, etc.The headbox is designed with customer performance parameters, which can ensure work performance.
4. The Crescent paper machine adopts full stainless steel hydraulic headbox.The distributing bundle is combined with diffusion tubes.The diffusion tube bundle adopts the diffusion-finally section tube through the precise calculation, horizontal distribution and dispersion to the pulp which is from the inlet pipe so that the pulp has the uniform distribution effect and good dispersion characteristics, which guarantees the quality of tissue paper.
Main Feature of head box:
1. Dedicated dilution water profile quantitative adjustment device can obtain better quantitative profile distribution;
2. High turbulence turbulence generator and special flap design can achieve better paper evenness;
3. Different designs are suitable for different vehicle speeds and paper types;
4. The addition of controllable edge flow to obtain good fiber orientation;
5. The upper lip plate adjustment mechanism of the structure can quickly and accurately adjust the quantification of the width;
6. The quick box opening design is convenient for maintenance and cleaning.
