Journey.
Pre-extrusion water valve 18 and relief valve 19 are all set on the pipeline of connection pressurising mouth 8, when in filter chamber material into full
Afterwards, pre-extrusion water valve 18 is opened, high pressure water is made to enter pre-extrusion room 7, diaphragm of rubber 5 expands, and squeezing calcium and magnesium material makes its molding
It for filter cake, is controlled by PLC, the time is set, is then closed, after the completion of pre-extrusion, opened relief valve 19, make in pre-extrusion room 7
Water flow away, be filter cake washing outflow space, next pre-extrusion water valve 18 opening before, close relief valve 19.
Wash water valve 20 is set in the import 10 of filter chamber 9 and the connecting line of scuttlebutt, when the rubber of pre-extrusion room 7
Diaphragm 5 expands, and after extruding calcium and magnesium material makes it be shaped to filter cake, opens wash water valve 20, to filter cake top into clear water, passes through water pump
High pressure, so that clear water is taken away solubility salt in filter cake, is controlled by PLC through filter cake, the time be set, is then closed.
Ancillary equipment: the containers such as size barrel, wash water bucket, scuttlebutt, mother vat are associated with by liquidometer with operated pneumatic valve, real
Existing automatic liquid level control.
It is equipped using the intelligence in the utility model and desalination dry technology handles calcium and magnesium mud, it is every that treated
Supplemental characteristic is as shown in table 1.
Table 1 is handled calcium and magnesium mud using the intelligence equipment in the utility model
Carry out that treated that parameters data are as shown in table 2 using traditional equipment and to calcium and magnesium mud.
2 traditional equipment of table handles calcium and magnesium mud
| Device name | Cl-(%) | Ca2+(%) | Mg2+(%) | SO4 2-(%) | Free water (%) |
