Background technology
Currently, countries in the world nuclear fuel reprocessing plant mostly uses greatly Purex flow.In the tail end process of Purex flow, need
The metal-nitrate solutions and oxalic acid solution of recycling generate oxalate precipitation slurries after completing precipitation reaction in precipitation reactor,
Then oxalate precipitation slurries need to be delivered to filter and be filtered to obtain filter cake for being further processed.
Existing oxalate precipitation slurries filter uses the structure type of circular filter plate, circular filter plate to be placed in cylinder
In shape container.Entire filter operation carries out under certain vacuum degree, and oxalate precipitation slurries enter from the top of filter, in circle
Filter cake is formed on shape filter plate, filtrate is flowed out from filter lower part.But this oxalate precipitation slurries filter there are the problem of
It is：Filter area is smaller to cause production capacity small；It is not easy to realize the regeneration of filtering material and replacement；It is not easy to realize oxalate precipitation
The discharging operations of filter cake.
Invention content
The object of the present invention is to provide a kind of oxalate precipitation slurry filters, can be post-processed for nuclear fuel
With larger filter area when the filter operation of factory's oxalate precipitation slurries, and filtering material regenerating easily and replace and grass
Hydrochlorate precipitated filter cakes are easy discharging.
In order to achieve this, in the embodiment on basis, the present invention provides a kind of oxalate precipitation slurry filter,
The filter device includes head cover, filter cup, cartridge filter, scraper, oxalate precipitation injection point pipe, filtrate exit pipe,
The filter cup compresses sealing as filter chamber, upper part by the head cover；
The cartridge filter as filter material is placed in the filter cup, (is attached to for detaching oxalate precipitation object
On the lateral wall of cartridge filter) and filtrate, upper part connection head cover；
Being provided between the filter cup madial wall and the cartridge filter lateral wall can be with the filter cup
The scraper to move up and down, for scraping the filter cake being attached on the cartridge filter lateral wall；
The oxalate precipitation injection point pipe connects the head cover above, be used for into the filter cup,
The oxalate precipitation slurries are passed through outside the cartridge filter；
The filtrate exit pipe connects the head cover above, for filtrate to be discharged from the cartridge filter.
In a preferred embodiment, the present invention provides a kind of oxalate precipitation slurry filter, wherein described
Filter device further include the lifting platform being placed in below the filter cup, for by its up and down motion drive described in filtering
Cup moves up and down, and adjusts the connection status of the filter cup and the head cover and the sealing tightness of the head cover
(head cover should seal compression filter cup when filtering, and head cover should be disconnected with filter cup when discharging after filtering), and make described scrape
Knife scrapes filter cake (declining certain altitude by filter cup to realize).
In a kind of more preferred embodiment, the present invention provides a kind of oxalate precipitation slurry filter, wherein
The filter device further includes the lifting hold-down mechanism being placed in below the lifting platform, for providing the lifting platform
The power of lower movement.
In a kind of more preferred embodiment, the present invention provides a kind of oxalate precipitation slurry filter, wherein
The lifting hold-down mechanism is elastic mechanism.
The beneficial effects of the present invention are, can be for core using the oxalate precipitation slurry filter of the present invention
With larger filter area when the filter operation of fuel reprocessor's oxalate precipitation slurries, and filtering material regenerating easily and
It replaces and oxalate precipitation filter cake is easy discharging.
Beneficial effects of the present invention are embodied in：
(1) filter device uses cast, simple and compact for structure, and filtering surface is considerably increased compared to plectane type filter
Product, is conducive to the raising of production capacity；
(2) filter device is easy to the regeneration and replacement that dismounting is filtered material；
(3) filter device uses the structure type of the filter cup with liftable included scraper, is conducive to unloading for filter cake
Material operation.
Description of the drawings
Fig. 1 is the side view of the oxalate precipitation slurry filter of the illustrative present invention.
Fig. 2 is the vertical view of the oxalate precipitation slurry filter of the illustrative present invention.
Specific implementation mode
The specific implementation mode of the present invention is further illustrated below in conjunction with attached drawing.
The structure of the oxalate precipitation slurry filter of the illustrative present invention is as shown in Figs. 1-2, including head cover 1, mistake
Filter bowl 2, cartridge filter 3, lifting platform 4, lifting hold-down mechanism 5, scraper 6, oxalate precipitation injection point pipe 7, filtrate exit pipe 8.
Filter cup 2 is used as filter chamber, is placed in above lifting platform 4, and lifting platform 4 is placed in 5 top of lifting hold-down mechanism.Filter cup
2 top seal stainless steels, disk-shaped head cover 1.
As filter material, material is that the cartridge filter 3 of sintered stainless steel is placed in filter cup 2, for detaching oxalate precipitation
Object filter cake (being attached on the lateral wall of cartridge filter 3) and filtrate, what upper part and 1 bottom of head cover were stretched out, which take over, connect.
It can be arranged between 3 lateral wall of 2 madial wall of filter cup and cartridge filter with the scraper 6 that filter cup 2 moves up and down,
For scraping the filter cake being attached on 3 lateral wall of cartridge filter after filtering.
