摘要:
The present invention relates to the field of lithium battery raw material preparation technologies, in particular to a production apparatus for hydrothermal synthesis of lithium iron phosphate. The production apparatus comprises first stirring devices, a preheating device, a second stirring device, and a drying device, wherein there are two first stirring devices, and the preheating device comprises a housing, a heating box, two feeding pumps, two first transfer assemblies, and several first heating tubes; the two first transfer assemblies each comprise an inlet pipe, an outlet pipe, and several transfer branch tubes. In the present application, the arrangement of multiple transfer branch tubes increases the heated surface area of the slurry, enhances the thermal conduction efficiency, and improves the heating effect. The equidistant arrangement of the transfer branch tubes ensures uniform heating of the slurry within the multiple transfer branch tubes, guaranteeing the heating effect. The arrangement of the preheating device can reduce the heating time of the slurry, thereby enhancing the heating effect

The invention provides a high-performance seafloor flexible oil storage system, which solves the problems of high storage cost and difficult maintenance of crude oil in offshore oilfields in the prior art. The oil storage system comprises an oil-water separator, a pressure pump and an input riser connected in sequence, the input riser extends downward below the sea level, and a pipeline and a plurality of flexible oil storage tanks with the same structure are arranged below the sea level. Each flexible oil storage tank is communicated with the pipeline through a control valve, the input riser is communicated with one end of the pipeline through a blocking valve and an input valve, and the other end of the pipeline is also sequentially connected with an outlet booster pump, an output valve and an output riser. The output riser extends upwards above the sea level, the output riser is connected to the tanker through a cooler and an output pump, and a concrete counterweight for fixing the invention to the seafloor is connected under the flexible storage tank. The high-performance seafloor flexible oil storage system of the invention has the advantages of simple structure, convenient maintenance and good practicability.
