Description

A kind of fourdrinier machine wet end

Technical field

The utility model belongs to pulp technology for making paper, is specifically related to a kind of fourdrinier machine wet end.

Background technology

Wet end is the major part of paper machine composition, this part is by sloughing the most of moisture in online paper stock, form l Water Paper page, the mode of its dehydration is filtered, suction dehydration, the usual water yield that can slough accounts for more than 95% of online deckering amount, finally obtain evenly and there is the l Water Paper page of certain wet strength, in fact, the formation of l Water Paper page is that fiber progressively deposits on wire side, fiber and fiber interweave mutually becomes the result of skim, fiber criss-cross arrangement on wire side is even, the uniformity that page full width is consistent could be formed, thickness, the paper of the high-qualitys such as intensity, current fourdrinier machine wet end usually due to Material selec-tion is improper or each several part operation parameter arrange improper, during causing wet end, service life is shorter, wet end electric current use amount is larger, electricity waste is caused while affecting the l Water Paper page uniformity.

Utility model content

The purpose of this utility model is for existing problem, provides a kind of fourdrinier machine wet end.

The utility model is achieved through the following technical solutions: a kind of fourdrinier machine wet end, comprise forming net, breast roll, forming board, table roll, dewatering plate, wet vacuum tank, dry vacuum case, ornamenting roller and couch roll is provided with successively along forming net upper surface, drive the bottom righthand side that net roller is located at forming net, forming net lower surface is provided with wite roll, spreader roll and idler roller, have white wate tray at dewatering plate, wet vacuum tank and dry vacuum case.

As further improvement of these options, described dewatering plate is provided with two groups, first be mounted on table roll after, second be mounted on wet vacuum tank after, wherein second group of dewatering plate number is the twice of first group of dewatering plate number.

As further improvement of these options, the material of described wet vacuum tank is zirconia ceramics.

As further improvement of these options, the vacuum ranges of described wet vacuum tank is: 80-120 millimetres of mercury, and the vacuum ranges of dry vacuum case is: 120-200 millimetres of mercury, is progressively increased respectively by left-to-right vacuum.

As further improvement of these options, described ornamenting roller is located between two groups of dry vacuum casees, and rotating speed is set to 150-200r/min.

As further improvement of these options, described idler roller is supporting is provided with stretcher and tension controller, and operationally, the tension force according to forming net regulates, and makes it remain enough tension force.

The utility model has the following advantages compared to existing technology:

(1) zirconia ceramics has the advantages such as hardness is high, ABRASION RESISTANCE good, toughness is high, coefficient of friction is low, good corrosion resistance, its coefficient of friction is very low, wet vacuum tank and dry vacuum case of wet end uses zirconia ceramics to overcome pottery fragility inherently, ABRASION RESISTANCE is higher, and its service life is greatly extended;

(2) the different dewatering plate of number is set respectively before wet vacuum tank with dry vacuum case, ensures dehydrating amount, the disturbance performance to slurry can be improved simultaneously, reduce power consumption;

(3) vacuum of described wet vacuum tank and dry vacuum case is set to and progressively increases, and contributes to l Water Paper page and evenly dewaters in advance process, reduces energy consumption;

(4) ornamenting roller is by the coated stainless (steel) wire of hollow roller drum, can reduce equipment cost, arranges corresponding rotating speed, can improve the evenness of l Water Paper page frame table bond strength and paper, and the two sides being lowered into paper is poor.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Wherein, 1-forming net, 2-breast roll, 3-forming board, 4-table roll, 5-dewatering plate, 6-wets vacuum tank, and 7-dry vacuum case, 8-ornamenting roller, 9-couch roll, 10-drives net roller, 11-wite roll, 12-spreader roll, 13-idler roller, 14-white wate tray.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is further illustrated.

As in Fig. 1, a kind of fourdrinier machine wet end, comprise forming net 1, breast roll 2, forming board 3, table roll 4, dewatering plate 5, wet vacuum tank 6, dry vacuum case 7, ornamenting roller 8 and couch roll 9 is provided with successively along forming net 1 upper surface, drive the bottom righthand side that net roller 10 is located at forming net, forming net 1 lower surface is provided with wite roll 11, spreader roll 12 and idler roller 13, has white wate tray 14 at dewatering plate 5, wet vacuum tank 6 and dry vacuum case 7.
