700X3850 Vacuum Suction Box

In the papermaking process flow, the vacuum dewatering box plays a crucial role. It is one of the key components in the wet part of the paper machine, mainly responsible for efficiently removing the moisture in the paper web and significantly increasing the dryness of the paper, laying a solid foundation for the subsequent drying and processing steps.

1.700 Indicates Width

The width value of 700 is of great significance. It determines the processing range that the vacuum dewatering box can cover in the transverse direction of the paper machine. A wider width helps to act more evenly on the entire transverse area of the paper web, reducing the non-uniformity of moisture distribution and ensuring the consistency of dryness in the transverse direction of the paper.

The reasonable design of the width of 700 can adapt to the needs of paper machines of different widths and match the overall structure and production capacity of the paper machine, improving production efficiency and the stability of paper quality.

2.3850 Indicates Length

The length design of 3850 plays a key role in the performance of the vacuum dewatering box. The longer length means that the contact time of the paper web with the dewatering box is prolonged, providing more sufficient time for the full absorption and discharge of moisture.

The longer length can increase the effective area of the vacuum action, enabling more moisture to be effectively extracted and further increasing the dryness of the paper to meet the requirements of the subsequent process for the paper dryness.

At the same time, the choice of length also needs to consider the speed and production capacity of the paper machine to ensure the achievement of the ideal dewatering effect within a given time without adversely affecting the production efficiency.

1.Vacuum Formation：Inside the vacuum dewatering box, a negative pressure environment is created through a vacuum pump or other vacuum generating devices. When the paper web passes over the dewatering box, this negative pressure attracts the moisture in the paper web, causing it to enter the inside of the dewatering box through the small holes or gaps on the box cover.

2.Moisture Discharge：The moisture that enters the dewatering box is guided orderly to the drainage pipe or collection device under the action of the internal diversion structure, thereby achieving the separation of moisture from the paper web.

3.Pressure Regulation：By precisely controlling the degree of vacuum and pressure, the intensity and speed of dewatering can be adjusted to adapt to the production needs of different types, basis weights, and paper machine speeds.

1.Efficient Dewatering：Capable of quickly and largely removing the moisture in the paper web, significantly increasing the dryness of the paper, thereby reducing the energy consumption and time cost of the subsequent drying process.

2.Uniformity of Dewatering：The reasonable structural design and parameter configuration ensure the uniformity of dewatering in the width and length directions of the paper, avoiding local over-drying or over-wetting situations, and improving the quality and performance stability of the paper.

3.Strong Adaptability：It can be adjusted and optimized according to different papermaking processes and paper varieties to adapt to various production conditions and requirements.

4.High Stability：During long-term continuous operation, it can maintain stable dewatering performance, reducing the impact of equipment failures or performance fluctuations on production.

1.Installation Key Points

When installing the vacuum dewatering box, it is necessary to ensure its precise alignment and connection with other components of the paper machine to ensure the smooth passage of the paper web.

The connection of the vacuum pipeline and the drainage pipeline should be tight to avoid leakage affecting the vacuum degree and drainage effect.

The selection of the installation position and angle should consider the overall layout and process flow of the paper machine to achieve the best dewatering effect.

2.Maintenance Key Points

Regularly inspect the surface and internal structure of the dewatering box, clean the clogged small holes or gaps to ensure the smooth intake and discharge of moisture.

Inspect the sealing performance and working performance of the vacuum system, and replace the worn seals and vacuum pump components in a timely manner.

Calibrate and maintain the pressure control system of the dewatering box to ensure the accuracy and stability of the dewatering pressure.
