Abstract
The utility model discloses a thickener with a filtering disc, comprising an outer shell and a filtering device fixed in the outer shell and formed by multiple filtering discs arranged in parallel. Filtering pores are evenly distributed in the filtering discs, and a central tube is fixedly connected with the centre of each filtering disc. By using the technical scheme, the thickener comprises the multiple filtering discs arranged in parallel and filtering meshes with evenly distributed small holes are arranged on the filtering discs, wherein each filter screen is unlikely to deform so that a good concentration effect can be acted on slurry, and the subsequent processing is convenient to carry out; and processed whitewater has low concentration and can be recycled well, thereby reducing the resource waste and protecting the environment.
Description
Technical field
The utility model relates to pulp technology for making paper, specifically, relates to a kind of thickener that filters disk that has.
Background technology
Concentrating is the important step in the paper technology, can the concentration of paper pulp be brought up to the required concentration of technology on the one hand, to make things convenient for the processing of subsequent handling; Can make the concentration of the plain boiled water that ejects lower on the other hand, 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 is that the circulating and recovering of plain boiled water is created good condition, thereby reduces the consumption 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; The rigidity of polyester webs is low in addition, and through use after a while, filter screen will be out of shape; 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 thickener that filters disk that has is provided, and this thickener concentrated effect is good, practices thrift cost, 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 thickener that filters disk that has comprises shell and the filter of being made up of a plurality of filtration disks that are arranged in parallel that is fixed in enclosure, filters disk and evenly is covered with filtering holes, and central tube is fixed in the center of filtration disk.
Further, the quantity of filtration disk is 6 to 18.
Further, filtering disk is the filtration disk that a plurality of fan-shaped discs are spliced into.
Further, each said filtration disk is spliced by 12 to 18 fan-shaped discs.
Further, each said filtration disk is spliced by 14 to 16 fan-shaped discs.
Compared with prior art, the beneficial effect of the utility model is:
Adopt above technical scheme, a kind of thickener that filters disk that has adopts a plurality of filtration disks that are arranged in parallel, and filters the screen pack that disk evenly is covered with aperture, and this screen pack is not yielding, makes that the concentrated effect of slurries is good, makes 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.
Description of drawings
Accompanying drawing is used to provide the further understanding to the utility model, is used to explain the utility model with the embodiment of the utility model, does not constitute the restriction to the utility model, in the accompanying drawings:
A kind of structural representation that has the thickener that filters disk of Fig. 1 the utility model.
A kind of structural representation that has the filtration disk of the thickener that filters disk of Fig. 2 the utility model.
Fig. 3 be among Fig. 2 A-A to structural representation.
Include among Fig. 1 to Fig. 3 with lower component:
1---fan-shaped disc;
2---filter disk;
3---filtering holes;
4---shell;
5---central tube.
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:
Like Fig. 1, the described a kind of thickener that filters disk that has of the utility model shown in Figure 3; Comprise the filter of forming by a plurality of filtration disks 2 that are arranged in parallel that shell 4 is inner with being fixed in shell 4; Filter disk 2 and evenly be covered with filtering holes 3, central tube 5 is fixed in the center of filtering disk 2.
Concrete, the quantity of filtering disk 2 is 6 to 18.It is many more to filter disk 2 quantity, and then filter effect is good more, but cost is also high more, therefore according to the needs of technology to slurry concentration, will filter disk 2 quantity and be decided to be 6 to 18.
Concrete, as shown in Figure 1, filter disk 2 and in thickener, rotate; Plain boiled water forms certain liquid level in thickener, plain boiled water can pass and filter in the middle gap of disk 2 each dish of entering, 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 on card through filtering disk 2, hit down by water under high pressure in the defeated sizing device in the exit and export.
In addition, 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 thickener that filters disk that has adopts a plurality of filtration disks 2 that are arranged in parallel, and filters the screen pack that disk 2 evenly is covered with aperture, and this screen pack is not yielding, makes that the concentrated effect of slurries is good, makes 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:
As shown in Figure 2, filter the filtration disk 2 that disk 2 is spliced into for a plurality of fan-shaped discs 1.Because the thickener volume is bigger, used filtration disk 2 volumes are also bigger, are not easy whole processing, therefore adopt whole filtration disk 2 is divided into a plurality of fan-shaped disc 1 processing, and the mode of assembling makes processing and manufacturing comparatively convenient then.
Concrete, each said filtration disk 2 is spliced by 12 to 18 fan-shaped discs 1.
Concrete, each said filtration disk 2 is spliced by 14 to 16 fan-shaped discs 1.
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.
