Description

Technical Field

[0001] The utility model relates to the field of reaction kettles, in particular to a reaction kettle for refining sodium tungstate. Background Art

[0002] Sodium tungstate is a white, shiny flaky crystal or crystalline powder, soluble in water, insoluble in ethanol, slightly soluble in ammonia, and weathering in the air. The existing sodium tungstate refining reactor usually completely evaporates the sodium tungstate solution to obtain sodium tungstate crystals, but other impurities in the solution will also precipitate and crystallize together, and will be mixed into the sodium tungstate crystals. In addition, the sodium tungstate refining reactor is not completely discharged, resulting in a decrease in the refining rate.

[0003] The existing patent application with application number CN201621382765.7 proposes a refined sodium tungstate reactor, which can effectively separate impurities and high-purity sodium tungstate crystalline particles, and use a stirring rod to scrape off the crystalline particles adhered to the inner wall of the reactor body and accelerate the unloading process, making the unloading convenient and fast. In the patent application with application number CN202122325845.6, a refined sodium tungstate reactor is also proposed, which solves the problems of slow cooling speed, high power consumption and high cost of restarting the heating equipment in the patent application with application number CN201621382765.7. However, it only uses gravity and a filter to dehydrate the sodium tungstate crystals, and the dehydration effect is poor. It is impossible to quickly and effectively remove the water in the sodium tungstate crystals, so that the taken out sodium tungstate crystals often need to undergo a secondary dehydration operation, which will reduce the work efficiency, so it needs to be improved.

There is a dehydration structure 4, which is composed of a pipeline bin 10, a cone tube 11, a connecting pipe 12, a feeding pipe 13 and an arc-shaped mesh plate 16. There are two cone tubes 11 and they are fixedly installed at the upper and lower ends of the pipeline bin 10 respectively. The connecting pipe 12 is fixedly installed at the upper end of the cone tube 11 on the upper side, and the feeding pipe 13 is fixedly installed at the lower end of the cone tube 11 on the lower side. The arc-shaped mesh plate 16 is fixedly installed on the pipeline bin 10. The pipeline bin 10 is connected to a cooling and dehydration fan 5. A connecting hole is opened on the pipeline bin 10 on the dehydration structure 4 14 and mounting groove 15, the arc mesh plate 16 is fixedly installed in the mounting groove 15, the outlet pipe on the cooling and dehydrating fan 5 is fixedly plugged into the connecting hole 14 opened on the pipeline bin 10, by installing the drain pipe 3 on the discharge pipe 2, installing the dehydrating structure 4 on the drain pipe 3, and installing the cooling and dehydrating fan 5 on the dehydrating structure 4, so that they cooperate with each other, the sodium tungstate crystals falling from the discharge pipe 2 will fall into the dehydrating structure 4 along the drain pipe 3, and part of the water will flow out from the mesh pipe 9 on the drain pipe 3. After the crystals fall into the dehydration structure 4, during the operation of the cooling and dehydration fan 5, the water mixed in the sodium tungstate crystals will be blown out from the arc mesh plate 16, and the sodium tungstate crystals will fall out of the discharge pipe 13 under the influence of gravity after contacting the arc mesh plate 16.

During this process, part of the water will flow out from the mesh holes at the mesh pipe 9 on the drain pipe 3 due to the influence of gravity. When the sodium tungstate crystals fall into the pipe bin 10 on the dehydration structure 4, the strong wind generated by the working cooling and dehydration fan 5 will blow the water mixed in the sodium tungstate crystals out from the mesh holes at the arc mesh plate 16, thereby completing the dehydration of the sodium tungstate crystals. After the sodium tungstate crystals contact the arc mesh plate 16, they will fall out of the discharge pipe 13 due to the influence of gravity. At the same time, when the sodium tungstate crystals are dehydrated, the strong wind generated by the cooling and dehydration fan 5 can also quickly cool them down.
