Description
Technical field
Concentrated acid preparing technical field is the utility model is related to, especially a kind of concentrated phosphoric acid clarification purifier.
Background technology
In industrial production, typically first then reaction slurry is subjected to solid-liquor separation by ground phosphate rock (slurry) and sulfuric acid reaction
To obtain wet dilute phosphoric acid, concentration finally is carried out to phosphoric acid,diluted to obtain concentrated phosphoric acid.
The patent of Application No. " 201020277407.6 ", by setting guide wire, after reducing concentrated phosphoric acid entrance
Impact, be so advantageous to the sedimentation of impurity in concentrated phosphoric acid, and the impurity after sedimentation will not also suspend again, and then shorten net
Change the sedimentation time needed for concentrated phosphoric acid.Although the device limits impact range when concentrated phosphoric acid falls to a certain extent,
The concentrated phosphoric acid whereabouts area, drop-off positions is set to be limited simultaneously, severe decrease concentrated phosphoric acid is accumulated with sedimentation agent direct contact surface, shadow
Ring reaction speed.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of concentrated phosphoric acid clarification purifier, reduces under the concentrated sulfuric acid
Fall caused impulsive force, and then reduce impurity and suspend, shorten the clarification time；In addition, it can be automatically performed continuously by repeatedly precipitating
Purification process.
In order to solve the above technical problems, technical scheme is used by the utility model：
A kind of concentrated phosphoric acid clarifies purifier, including container body, is provided with the taper bucket in container body, the taper bucket upper end and
Inlet connection, lower end are connected with spiral conveying tube, and helical feed bottom of the tube is provided with expanding opening, and opening lower section face is provided with
Perforated plate, for the container body below perforated plate built with sedimentation agent, container body side is provided with Multistage settling pond, leads in settling tank
Cross multiple dividing plates and be divided into multiple decanting zones, decanting zone side is provided with collecting region, liquid outlet is provided with collecting region.
The spiral conveying tube, perforated plate are made of pvc material.
Dividing plate in the settling tank successively shortens successively by sedimentation.
The spiral conveying tube can be multiple, and spiral conveying tube is distributed from inside to outside by diameter and upper and lower side passes through
Corresponding connector is connected respectively with the taper bucket, perforated plate or face.
The container body is diminishing truncated cone-shaped, spiral conveying tube profile are mutually fitted with container body from top to bottom
Should, supporting plate is hinged with by the pin with back-moving spring on container body two side, welding is corresponded in the side wall of supporting plate lower end
Limited location block, the supporting plate coordinate with the setter plate on spiral conveying tube, spiral conveying tube are supported.
A kind of concentrated phosphoric acid clarification purifier of the utility model, has following technique effect：
1）, by setting spiral conveying tube, and perforated plate is set below spiral conveying tube, reduction of speed under concentrated phosphoric acid can be reduced
Degree, while expand concentrated phosphoric acid and the contact area of sedimentation agent, it thus is avoided that when concentrated phosphoric acid falls and again evokes sediment, it is heavy to improve
Efficiency drops.
2）, by setting Multistage settling pond, continuous multi-stage sedimentation can be carried out to concentrated phosphoric acid, because settling tank is led to using overflow
Cross, and last area is arranged to collecting region, such sediment carries out multi stage precipitation, concentrated phosphoric acid can be arranged directly after multistage purification
Go out, condition is provided for continuous production.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples：
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is that multiple spiral conveying tubes install top view in the utility model.
Fig. 3 is the schematic diagram of spiral conveying tube removable support member in the utility model.
In figure：Container body 1, the taper bucket 2, inlet 3, spiral conveying tube 4, opening 5, perforated plate 6, sedimentation agent 7, sedimentation
Pond 8, decanting zone 9, collecting region 10, liquid outlet 11, supporting plate 12, limited block 13, setter plate 14.
Embodiment
As shown in Figure 1-2, a kind of concentrated phosphoric acid clarification purifier, including container body 1, container body 1 is interior to be provided with taper
Bucket 2, the upper end of the taper bucket 2 is connected with inlet 3, lower end connects with spiral conveying tube 4, and the bottom of spiral conveying tube 4 is provided with expanding
Opening 5,5 lower section faces of opening are provided with perforated plate 6, and the container body 1 of the lower section of perforated plate 6 is built with sedimentation agent 7.Due to spiral transferring
Send the inclination angle of every section of pipe can be by itself design setting, and concentrated phosphoric acid decrease speed can be slowed down for straight line declines,
Impact after perforated plate 6, is fallen, speed after perforated plate 6 hinders again after tubaeform expanding opening 5 comes out again
More reduce by one layer.Scatter further, since concentrated phosphoric acid tilts to impact on perforated plate after dropping out from spiral conveying tube, so fall on
Behind the bottom of container body 1 more uniformly, increased with sedimentation agent contact area, will not evoke sediment while improving reaction speed.
Because traditional clarification purifier is arranged in a tank body, when reach certain time, it is a certain amount of after it is just logical
Cross liquid outlet outflow.Such case can only carry out concentrated phosphoric acid clarification and output gap, can not be worked continuously.In order to meet
The efficient production of continuous input purification and output storage, Multistage settling pond 8 can be provided with the side of container body 1, is led in settling tank 8
Cross multiple dividing plates and be divided into multiple decanting zones 9, sedimentation agent 7 is placed with decanting zone 9, the side of decanting zone 9 is provided with collecting region 10, collects
Liquid outlet 11 is provided with area 10.So, concentrated phosphoric acid overflow after one-level settles enters next stage, will not due to natural transition
Impact is produced, i.e., will not evoke precipitation, and after realizing multistage purification, is discharged after eventually entering into collecting region 10.
The spiral conveying tube 4, perforated plate 6 are made of pvc material.
Dividing plate in the settling tank 8 successively shortens successively by sedimentation.Because the impurity in last concentrated phosphoric acid is fewer and fewer,
Therefore from front to back also can be shorter and shorter in each area's residence time, it by reasonably designing, will control in the reaction time most short, carry
High purification efficiency.
The spiral conveying tube 4 can be multiple, and spiral conveying tube 4 is distributed from inside to outside by diameter and upper and lower side leads to
Cross corresponding connector respectively with the taper bucket 2, perforated plate 6 is connected or face.Thus inlet can be increased.
The container body 1 is diminishing truncated cone-shaped from top to bottom, the profile of spiral conveying tube 4 and the phase of container body 1
Adapt to, supporting plate 12 is hinged with by the pin with back-moving spring on the two side of container body 1, it is right in the side wall of the lower end of supporting plate 12
Limited block 13 should be welded with, the supporting plate 12 coordinates with the setter plate 14 on spiral conveying tube 4, spiral conveying tube 4 is carried out
Support.So, when spiral conveying tube needs to change, because supporting plate 12 can be dug upwards, during taking-up, spiral conveying tube 4 is not
It is restricted, it is only necessary to directly take out；It is supported after being put into by the supporting plate 12 with limited block 13.
