Description

A kind of big span thickener

Technical field

The utility model relates to pulp technology for making paper, specifically, relates to a kind of big span thickener.

Background technology

Concentrating is the important step in the paper technology, on the one hand, can the concentration of paper pulp be brought up to the required concentration of technology, to make things convenient for the processing of subsequent handling; On the other hand, also can make the concentration of the plain boiled water that ejects lower, reach standard; Let fiber staying in the paper pulp and do not run off as much as possible, improve the utilization rate of fiber, simultaneously; The plain boiled water that concentration is lower also is that the circulating and recovering of plain boiled water is created good condition, thereby reduces the use amount of clear water.

What the tradition thickener used is polyester webs, and it is easy to generate distortion in the environment of cold and hot variation, and just has cold and hot variation in the slurrying production technology; In addition, the rigidity of polyester webs is low, through use after a while; Filter screen will be out of shape, and a large amount of fibers run off from the opening of sieve of distortion, cause waste; And processing brings difficulty, contaminated environment to paper waste.

Summary of the invention

The utility model has overcome defective of the prior art, and a kind of big span thickener is provided, and the concentrated effect of this big span thickener is good, not only practices thrift cost, but also the protection environment.

In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme:

A kind of big span thickener; Comprise the filter that shell and the dish by a plurality of stainless steel circles that are arranged in parallel that is fixed in enclosure are formed; Disk evenly is covered with filtering holes, the disk of disk for being spliced into by a plurality of fan-shaped discs, and central tube is fixed in the center of stainless steel disk.

Further, the quantity of disk is 6 to 18.

Further, each said disk is spliced by 12 to 18 fan-shaped discs.

Further, each said disk is spliced by 14 to 16 fan-shaped discs.

Further, fan-shaped disc is corrugated fan-shaped disc.

Compared with prior art, the beneficial effect of the utility model is:

Adopt above technical scheme, a kind of big span thickener adopts a plurality of stainless disks that are arranged in parallel; Disk evenly is covered with the screen pack of aperture; The disk of disk for being spliced into by a plurality of fan-shaped discs, this screen pack is not yielding, and has increased the contact area of screen pack and plain boiled water; Make that the concentrated effect of slurries is good, make things convenient for subsequent handling processing; White water consistency after the processing is lower, helps the recycle of plain boiled water, reduces the wasting of resources, the protection environment.

The specific embodiment

Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.

Embodiment 1:

The described a kind of big span thickener of the utility model; Comprise the filter of forming by a plurality of stainless disks 2 that are arranged in parallel that shell 4 is inner with being fixed in shell 4; Disk 2 evenly is covered with filtering holes 3; The disk 2 of disk 2 for being spliced into by a plurality of fan-shaped discs 1, central tube 5 is fixed in the center of stainless steel disk 2.

Concrete, because the thickener volume is bigger, used disk 2 volumes are also bigger, are not easy whole processing, therefore adopt whole disk 2 is divided into a plurality of fan-shaped disc 1 processing, the mode of assembling makes processing and manufacturing comparatively convenient then.

The quantity of disk 2 is 6 to 18.Disk 2 quantity are many more, and then filter effect is good more, but cost is also high more, therefore according to the needs of technology to slurry concentration, disk 2 quantity are decided to be 6 to 18.

Concrete, like Fig. 1, shown in Figure 2, disk 2 rotates in thickener; Plain boiled water forms certain liquid level in thickener, plain boiled water can pass stainless steel disk 2 and get in the middle gap of each dish, finally converges in the central tube 5 and discharges; Form drop during discharge and in each dish, form vacuum; Help the filtration of water more, the fiber in the plain boiled water can not form one deck slurry through disk 2 on card, is hit down by water under high pressure in the defeated sizing device in the exit and exports.

Filtering holes 3 can be not limited only to the circle shown in the figure for circle, ellipse, rhombus, different shape such as square.

Adopt above technical scheme, a kind of big span thickener adopts a plurality of stainless steel disks 2 that are arranged in parallel; Disk 2 evenly is covered with the screen pack of aperture, and this screen pack is not yielding, and has increased the contact area of screen pack and plain boiled water; Make that the concentrated effect of slurries is good, make things convenient for subsequent handling processing; White water consistency after the processing is lower, helps the recycle of plain boiled water, reduces the wasting of resources, the protection environment.

Embodiment 2:

The main technical schemes of present embodiment is identical with embodiment 1, and unaccounted characteristic adopts the explanation among the embodiment 1 in the present embodiment, no longer gives unnecessary details at this.The difference of present embodiment and embodiment 1 is:

Like Fig. 2, shown in Figure 3, preferred, each disk 2 is spliced by 12 to 18 fan-shaped discs 1.Disk 2 is split into 12 to 18 fan-shaped discs 1, and size to fit is convenient to the processing assembling of disk 2.

Each disk 2 is spliced by 14 to 16 fan-shaped discs 1.

Embodiment 3:

The main technical schemes of present embodiment is identical with embodiment 2, and unaccounted characteristic adopts the explanation among the embodiment 2 in the present embodiment, no longer gives unnecessary details at this.The difference of present embodiment and embodiment 2 is:

Like Fig. 2, Fig. 3, shown in Figure 4, fan-shaped disc 1 is corrugated fan-shaped disc 1.As shown in Figure 3, be fan-shaped disc 1 structural representation, whole filtration disk 2 cross sections are like Fig. 3, waveform shown in Figure 4, the subwave shape wave of in Fig. 2, only drawing sketch map, but can not think that the part that only limits to draw among the figure is waveform.Increase the real contact area that filters disk 2 and plain boiled water, make filter effect better, reduce the wasting of resources, make plain boiled water be convenient to recycle.

What should explain at last is: more than be merely the preferred embodiment of the utility model; Be not limited to the utility model; Although the utility model has been carried out detailed explanation with reference to embodiment; For a person skilled in the art, it still can be stated scheme to the skill that aforementioned each embodiment put down in writing and make amendment, and perhaps part technical characterictic wherein is equal to replacement.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
