Description

Continuous operation's phosphorite thick liquid filter equipment

Technical Field

The utility model belongs to the technical field of phosphorite processing, and particularly relates to a continuously operated phosphorite slurry filtering device.

Background

The phosphorite resource reserves in China are rich, but the high-grade phosphorite reserves are low, the price is high, and the phosphorite used in the phosphorite chemical industry production is mostly medium-low grade phosphorite. The low-and-medium grade phosphorite has large general hardness and many impurities, and the phosphorite pulp mixed with water after being ground by a ball mill contains small-particle phosphorite and impurity particles. When phosphorite slurry passes through the suction pump, small-particle phosphorite and impurity particles can influence the operation of the suction pump, even block the impeller of the suction pump, damage the suction pump and increase the maintenance cost. In the phosphating reaction, the reaction rate of phosphorite slurry containing small-particle phosphorite and impurity particles is low, and the impurity particles in the reaction product are difficult to separate. In order to solve the problems, a filter screen is arranged in a phosphorite slurry conveying channel, and small-particle phosphorite and impurity particles in phosphorite slurry can be separated from the filter screen, but the filter screen is difficult to treat and clear, so that the conveying channel is easy to block, and the production is influenced. If the separated small-particle phosphate ores and impurity particles are to be removed, the conveying channels are required to be stopped, continuous operation cannot be performed, and the production efficiency is reduced.

For example, chinese patent with publication number CN205760019U discloses a continuous operation's phosphorite slurry filter equipment, including inlet pipe, shunt tubes, stop valve, flange, rose box, close flow tube, discharging pipe, filter screen and play silt mouth, the shunt tubes is being connected to the inlet pipe, is being provided with the stop valve on two branches of shunt tubes, and two branches of shunt tubes are passing through flange joint rose box, and two rose boxes are being connected the both ends that close flow tube, and the confluence tube is being connected out the silt mouth, be provided with the filter screen in the rose box, the rose box lower extreme that the filter screen is close to flange one side is provided with out the silt mouth, is provided with the stop valve on the play silt mouth. The utility model can fully filter and remove impurities in the phosphorus ore pulp, is convenient for removing impurities and can continuously operate.

This patent suffers from several drawbacks in use, such as: the rose box in this patent only filters granule phosphate rock and impurity granule in the phosphorus ore pulp through the individual layer filter screen, in actual production application, because phosphorus ore slurry velocity of flow is faster, when the phosphorus ore slurry that contains granule phosphate rock and impurity granule touches the filter screen, can produce secondary impact to the little granule phosphate rock that the rose box bottom had deposited and impurity granule, receive little granule phosphate rock and impurity granule after the impact can constantly sink and float in the rose box, make the rose box to the filter effect of little granule phosphate rock and impurity granule relatively poor, the secondary work load of filter screen has been increased simultaneously, the life of filter screen has been reduced, in addition, can't clear up in time and change its inside filter screen in the rose box in this patent, make the filter screen in the device filter the phosphorus ore slurry after filtering the processing for a certain time, its filter effect decline, and change the rose box main part then the cost is higher, be unfavorable for saving manufacturing cost. In view of this, we propose a continuous operation phosphorus ore slurry filtration device.
