Description

Technical Field

[0002] Sodium aluminate, also known as sodium metaaluminate, is a white granule that is hygroscopic, highly soluble in water, insoluble in ethanol, and its aqueous solution is strongly alkaline. The sintering method can be used to prepare sodium metaaluminate. The specific steps are: finely mix bauxite, soda ash and limestone, sinter at high temperature, leaching the clinker with water, removing silicon from the sodium aluminate solution after leaching, obtaining a refined sodium aluminate solution, and evaporating to dryness to obtain the finished sodium aluminate product.

[0003] In the process of preparing sodium aluminate finished product from sodium aluminate solution, a concentration reaction device is required to evaporate the liquid in the sodium aluminate solution. When a common sodium aluminate concentration reaction device is in use, its heating source is generally set at the bottom of the concentration reaction device, which will cause the bottom of the concentration reaction device to heat faster, while other parts will heat up slower, thereby causing a temperature difference, resulting in uneven heating of the sodium aluminate solution inside the device, and the sodium aluminate crystals at the bottom of the device precipitate faster and condense at the bottom of the device, which reduces the heat conduction efficiency, thereby affecting the overall evaporation efficiency of the sodium aluminate solution.

At the same time, the scraper 23 can scrape off the sodium aluminate crystals precipitated on the inner wall of the evaporation cylinder 7, so that the heat conduction effect is better.

[0030] The working principle and use process of this utility model:

[0031] A certain amount of sodium aluminate solution is injected into the evaporation cylinder 7, the first hydraulic cylinder 8 is controlled to push the sealing plate 18 to buckle the cover on the evaporation cylinder 7, the lock buckle 19 is used to lock the evaporation cylinder 7 and the sealing plate 18, and the electromagnet 9 is powered off so that the electromagnet 9 no longer attracts the iron block 10. After that, the first hydraulic cylinder 8 is controlled to pull the electromagnet 9 upward so that the electromagnet 9 is separated from the iron block 10, and the heating furnace 11 is started to heat the evaporation cylinder 7. The evaporation cylinder 7 transfers heat to the sodium aluminate solution, so that the liquid is gasified and discharged along the exhaust pipe 20, and the sodium aluminate crystals are precipitated. In order to prevent the evaporation cylinder 7 from being heated too concentratedly, the first hydraulic cylinder 8 can be controlled to push the sealing plate 18 to buckle the cover on the evaporation cylinder 7, and the sealing plate 18 is locked on the evaporation cylinder 7. The motor 12 drives the third gear 13 to rotate. With the help of the mutual meshing of the third gear 13 and the first gear 3, the first gear 3 can be pulled to rotate, so that the first gear 3 drives the evaporation cylinder 7 to rotate in the horizontal direction. The rotation direction of the first motor 12 is switched, so that the rotation direction of the evaporation cylinder 7 is switched accordingly. At the same time, the second hydraulic cylinder 16 is controlled to pull the rack 15 to move. With the help of the mutual meshing of the rack 15 and the second gear 6, the second gear 6 can be pulled to rotate back and forth in the longitudinal direction. The mutual cooperation of the two allows the various parts of the evaporation cylinder 7 to be close to the heat source position in sequence and order, so as to better conduct heat to the sodium aluminate solution.

[0032] During the heating process of the evaporation cylinder 7, the second motor 25 is controlled to drive the transmission rod 22 to rotate, so that the transmission rod 22 pulls the scraper 23 and multiple stirring rods 24 to rotate, and the stirring rods 24 are used to drive the sodium aluminate solution inside the evaporation cylinder 7 to turn over, so that it is heated more evenly. At the same time, the scraper 23 can scrape off the sodium aluminate crystals precipitated on the inner wall of the evaporation cylinder 7, so that the heat conduction effect is better. After a period of time, the sodium aluminate crystals are basically precipitated, the heating furnace 11 is turned off, and the sodium aluminate solution inside the evaporation cylinder 7 can be completely evaporated by the residual heat of the evaporation cylinder 7. After the second motor 25 is controlled to pull the scraper 23 to scrape the sodium aluminate crystals from the inner wall of the evaporation cylinder 7, the sodium aluminate crystals in the evaporation cylinder 7 can be taken out.
