The utility model discloses can effectual restriction filter cake thickness, make it blot the process in reasonable thickness within range, experience, obtain filter cake more dry, that moisture is lower.
Description
Technical field
This utility model is related to filter cake thickness limits device technical field, especially relates to a kind of filter cake of disk filter
Thickness limits device.
Background technology
Disk filter is widely used in the fine fractions such as the filtration of aluminium hydroxide seed, coal industry flotation concentrate and mine tailing
The industry-by-industries such as the solid-liquid separation of granule, now expand it and are applied to power plant desulfurization gypsum dewatering slurries field.
The filter disc of ventional disc filter rotates in the filter cell body filling with slurry, by the work of the negative pressure of vacuum pump
It is used for adsorbing material, form filter cake, reach the purpose of solid-liquid separation.
When two grades of dehydration equipments being dehydrated disk filter as power plant's gypsum slurries, its charging is that lime stone slurry is inhaled
Receive so2The serosity generating afterwards, concentrates, through one-level hydrocyclone, the gypsum slurries that concentration is 40% ~ 50% after oxidation, due to technique
Its feed property of reason is very unstable, and concentration change is very big.If charging is solid contain very high, the filter cake of formation very thick it is not easy to inhale
Dry, the discharging to after discharge zone, the filter cake moisture content obtaining is higher, the comprehensive utilization of impact Gypsum Fibrosum subsequent treatment.
Content of the invention
In order to solve the above problems, for the high gypsum slurries of concentration, utility model provides a kind of disk filter filter
Cake thickness limits device.
To achieve these goals, the technical solution of the utility model is:
A kind of disk filter filter cake thickness limits device, comprising: filter disc 1, cell body 3, filter cake thickness limits device 4, institute
State and in cell body 3, be provided with filter disc 1, the position that filter disc 1 turns over 45 ° of discharge side horizontal line turns over the filter in the range of 180 ° again to it
The both sides of disk 1 are each provided with limiting the filter cake thickness limits device 4 of filter disc 1 outer surface filter cake 2 thickness, and described filter cake thickness limits
Device 4 is made up of a row or multi-row scraping article that filter disc both sides are respectively respectively provided with.
Compared with prior art, this utility model has the advantages that
A kind of disk filter filter cake thickness limits device, effectively can limit filter cake thickness so as to reasonably thick
In the range of degree, experience blots process, is more dried, filter cake that moisture is lower.
Brief description
Fig. 1 filter cake thickness limits device front view；
Fig. 2 filter cake thickness limits device a-a sectional view
In figure labelling: 1, filter disc；2nd, filter cake；3rd, cell body；4th, filter cake thickness limits device.
Specific embodiment
Explanation this utility model that can be detailed by the following examples, open the purpose of this utility model is intended to protect
All technological improvements in the range of this utility model.
As shown in Figure 1, 2, a kind of disk filter filter cake thickness limits device, comprising: filter disc 1, cell body 3, filter cake thickness
Limits device 4, is provided with filter disc 1 in described cell body 3, the position that filter disc 1 turns over 45 ° of discharge side horizontal line turns over 180 ° again to it
In the range of filter disc 1 both sides be each provided with limit filter disc 1 outer surface filter cake 2 thickness filter cake thickness limits device 4, described
Filter cake thickness limits device 4 is made up of a row or multi-row scraping article that filter disc both sides are respectively respectively provided with.
Wherein, filter disc 1 rotates in the cell body 3 equipped with slip, as illustrated the direction of rotation shown in Fig. 1, turns in filter disc 1
The position that 45 ° of discharge side horizontal line turns over the both sides of the filter disc 1 in the range of 180 ° again to it, and each filter cake thickness of installing limits dress
Put 4, wipe unnecessary filter cake 2 on filter disc 1 off, the filter cake thickness after making to leave limits device is uniformly constant.
The both sides that the position turning over 45 ° of discharge side horizontal line in filter disc 1 turns over the filter disc 1 in the range of 180 ° again to it are each
It is respectively provided with a row or multi-row scraping article, the distance of this scraping article and filter disc 1 can limit the thickness of filter cake, the thickness limit of filter cake
It is made as 5 30mm, the unnecessary filter cake that will be greater than this thickness scrapes in slurry vessel, thus limiting filter cake thickness in rational model
In enclosing.The filter cake that fanning strip is formed after producing is the suitable filter cake of thickness.
This utility model is simple, has been supplied in the operation of disk filter.
