Hydrofoil Box with Ceramic Tops for Paper Machinery

Product Description

Company Profile

Huatao Group is set up in 2008. The main business is to serve the pulp and paper industry by providing quality accessories and paper machine enovation services to help customers solve various problems in production, improve production efficiency and reduce energy consumption.

Huatao Group has a professional technician team that devoted to pulp and paper industry. We are able to make the best proposal after completely analyzing and figuring our problems of the paper production line though paper-making progress, equipment, electric automatization and so forth.

We follow the "short process" concept in implementing the customer's projects to reduce energy and water consumption. On the premise of quality assured, running speed of paper machine are made in the best condition and manufacture cost decreased on the bottom. 

In addition to providing equipment, it is more important to provide technical services, including engineering, system integration and equipment upgrade services.
 

Product Description

Dewatering Element
The dewatering elements used in paper machines include dewatering board (or wiper board), forming board and vacuum suction tank panel. The pulp is leveled through the forming board, and a small part of water is removed at the same time. Then it enters the dehydration plate to scrape off the moisture, and finally enters the vacuum suction tank panel for forced dehydration by vacuum.

Component
1. Forming board: The forming board is the first element under the net of the chest roller of the paper machine, which plays the role of water removal to support the net and control the net section. The box is made of stainless steel, the substrate is super high molecular polyethylene or glass fiber reinforced plastic, and the panel is inlaid with ceramic.

2. Scraper Blades: Scraper Blades of various widths and forms are available to suit different requirements. Wiper plates are made of ceramic in various forms, with a 0-3 degree rear Angle. The transition bottom plate adopts the modern special treatment material FRP composite material, one - time molding. No processing, no deformation, accurate size, easy to paste.

3. Vacuum suction box: It is a kind of device that uses the high pressure difference inside and outside the box to enhance dehydration. The dryness of the wet paper is about 2 ~ 3% before passing through the vacuum box, and it can reach 10 ~ 14% after passing through the vacuum box, and the paper tightness is also increased.

4. Felt vacuum box:The felt suction box includes a box body, on which a dehydration panel is arranged, and the dehydration panel includes a bottom supporting plate.

Our Advantages

1.We use high precision processing, fine processing can effectively avoid the paper disease caused by the retention of fine fibers and the pulping phenomenon, and extend the service life of the forming fabric and felt.

2.Overall surface is flat, smooth and delicate. In the process of use, water film is generated between the fabric and the dewatering element, which improves the wear resistance, greatly reduces the driving energy consumption of the fabric and the felt, improves the service life and saves electricity.

3.High efficiency of dehydration, easy control of waterline, no instant dehydration positive and negative pressure pulse, avoid pulp topping, avoid the formation of paper in the dehydration process, reduce the difference between two sides of paper, greatly improve the evenness and smoothness of paper.

4.This product has a unique anticorrosion material, suitable for all kinds of dewatering environment.

We will be based on different paper machine and different types of paper ,supply strong applicability of the dehydration components to you.For you to create a high - grade paper condition.
