Ceramic Dewatering Elements Cover Low Vacuum Suction Box for Fourdrinier Paper Machine

Product Description

***Forming board box***Dewatering box***Low vacuum suction box***High vacuum suction box***Felt suction box*** The suction box dewatering is based on the suction effect of the vacuum pump, which generates a high pressure difference between the top and bottom of the paper to force the dewatering of the wet paper. It help to transfer the paper to the press section with a higher dryness.
In the jet-fixing process, the suction box is installed under each spunlace device. It adopts a vacuum suction type. The suction box sprays the water from the spunlace head on the supporting net curtain into the water vapor separator. After that, the air is discharged by the blower, and the water is sent to the filtering device by the pipeline through the pipeline. The moisture content of the web after water absorption can be reduced to 25% to 35% Forming Plate/board
The special design structure of the forming plate/board is that it can be installed near the breast roller, or the breast roller scraper can be installed. It can move forwards and backwards, and can be adjusted to the best spraying point of the slurry, so that it can achieve a good sheet forming and dewatering effect. . The forming board is composed of a box body and a panel. The box body is made of stainless steel.The box body is annealed or moved to eliminate stress, reduce deformation, so as to ensure quality, and the surface is sandblasted to make the appearance beautiful and generous.
Wiper plate/suction cover
The structure design of the wiper board is reasonable. According to the paper machine, paper type, and vehicle speed, the angle of the back panel can be designed to be 0~2.5 degrees to improve the dehydration effect and the formation of the paper. The dehydration board is composed of a box body and a panel. The box body is made of stainless steel.The box body is annealed or moved to eliminate stress, reduce deformation, so as to ensure quality, and the surface is sandblasted to make the appearance beautiful and generous.
Ceramic/HDPE suction cover
The panel/suction cover is processed as a whole, using special machine tools and special processing technology, so that the overall processing accuracy is high, the surface is smooth, and the finish is high, smooth and delicate. During use, it can avoid the retention of fine fibers and the paper defects caused by the top slurry phenomenon, and it is easy to control Waterline avoids the unfavorable paper sheet formation during the dehydration process, reduces the difference between the two sides of the paper, greatly improves the uniformity and smoothness of the paper, creates a water film between the net and the dehydration element, and improves wear resistance. Greatly reduce network consumption and energy consumption.
Felt suction box/foil
The structure design of the felt suction box/foil is a sealed structure. It is sucked by a vacuum pump to accelerate the drying of the paper, enhance the dehydration effect and the formation of the paper. Both ends of the panel are equipped with adjusting blocks to adjust the width of the suction opening of the paper sheet. The felt suction box is composed of a box body and a panel. The box body is made of stainless steel. The box body is annealed or moved to eliminate stress, reduce deformation, so as to ensure quality, and the surface is sandblasted to make the appearance beautiful and generous
The panel/suction cover is divided into:
1. HDPE suction cover 2.glass microcrystalline suction cover
3. Zirconia ceramic suction cover 4. alumina ceramic suction cover
according to different paper machines, different paper types, different speeds, customers can choose different panels. High vacuum suction box
The high-vacuum suction box has a reasonable structure design and is a sealed structure. It is sucked by a vacuum pump to make the paper sheet from low-pressure dehydration to high-pressure rapid dehydration, thereby speeding up the drying of the paper, enhancing the dehydration effect and forming the paper. Both ends of the panel are equipped with adjusting blocks to adjust the width of the suction opening of the paper sheet. The adjustment block is also equipped with a lubrication device, which can reduce the coefficient of friction by lubricating with clean water and increase the service life of the net. The vacuum suction box is composed of a box and a panel. The box is made of stainless steel. The box body is annealed or moved to eliminate stress and reduce deformation, thereby ensuring quality. The surface is sandblasted to make the appearance beautiful and generous.

according to different paper machines, different paper types, different speeds, customers can choose different panel Wet Suction Box
The structure of the Vacuum wet suction box is reasonable. Pay attention to its installation direction, distinguish the left and right mobile phones, generate negative pressure through the water leg to increase the dehydration capacity, and then the wet suction box is sucked by the vacuum pump to make the paper sheet transition from natural dehydration to low pressure dehydration, speeding up the paper The page is dry. The wet suction box is sealed. Both ends of the panel are equipped with adjustment blocks to adjust the width of the suction opening of the paper sheet. The adjustment block is also equipped with a lubrication device. It can reduce the friction coefficient and reduce the net consumption by lubricating with water. The rear corner of the panel can also be designed. ~1.5 degree angle, to enhance the dehydration effect and the forming of the paper sheet. The wet suction box is composed of a box body and a panel. The box body is made of stainless steel. The box body is annealed or moved to eliminate stress, reduce deformation, so as to ensure quality, and the surface is sandblasted to make the appearance beautiful and generous

Product Features Of Our De-watering Elements
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 conditions.
