Abstract
The utility model relates to an alkaline hydrolysis tank for rare earth production, which belongs to the field of the technical design of the alkaline hydrolysis tank for the rare earth production. The alkaline hydrolysis tank comprises an alkaline hydrolysis tank body, wherein the outer side wall of the alkaline hydrolysis tank body is coiled with a vortex electric heater. The alkaline hydrolysis tank is characterized in that the inner part of the alkaline hydrolysis tank body is provided with a to-be-corroded tank body of which the shape is similar to that of the alkaline hydrolysis tank body, the outer diameter of the to-be-corroded tank body is smaller than the inner diameter of the alkaline hydrolysis tank body, and the tank top of the to-be-corroded tank body is connected with the tank top of the alkaline hydrolysis tank body. According to the alkaline hydrolysis tank disclosed by the utility model, the alkaline hydrolysis tank is formed by adopting two layers of tank bodies and three layers of tank bottoms, when the alkaline hydrolysis tank is in use and when a strengthened corrosion tank bottom at the inner part of the to-be-corroded tank body is corroded to generate a hole and the leakage starts, the alkaline hydrolysis tank is not needed to be replaced and maintained and can be continuously used, the alkaline hydrolysis tank can be replaced until the tank bottoms of the to-be-corroded tank body are completely corroded, thus the full utilization of the strengthened corrosion tank bottom is ensured, the vortex electric heater is protected as well, the replacing period of the alkaline hydrolysis tank body is prolonged, the maintenance frequency is reduced, and the maintenance cost is lowered.
Description
Technical field
The utility model relates to a kind of alkaline hydrolysis tank for Rare Earth Production, belongs to Rare Earth Production alkaline hydrolysis tank technical project field.
Background technology
The alkaline hydrolysis tank is used in Rare Earth Production alkaline hydrolysis workshop section, and the production technique of this workshop section is to produce 150 degree high temperature with the electrically heated mode of eddy current, decomposes rare-earth mineral with NaOH under this high temperature.Because NaOH is fairly obvious to corrosion of metal under 150 degree high temperature, very high for the anticorrosive metal performance requriements of making the employing of alkaline hydrolysis tank, other metals except metallic nickel are substantially all improper.But adopt metallic nickel making equipment cost too high, therefore the method that usually adopts is to make the alkaline hydrolysis tank with the plain carbon stool plate, in the coiling of alkaline hydrolysis tank outer side wall the eddy current electric heater is arranged, and then comes into operation, after using for some time, according to corrosion condition periodic replacement alkaline hydrolysis tank.In this case, basically just needed to change an alkaline hydrolysis tank in per 3 to 4 months, 12 alkaline hydrolysis tanks of full factory are annual to be needed to change to be about 36 times altogether, each replacing time was about about 5 days, add up to approximately 180 days, have a strong impact on workshop output, and upkeep cost is higher, expense is about 430,000 yuan, and is time-consuming.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of alkaline hydrolysis tank for Rare Earth Production is provided, has prolonged the alkaline hydrolysis tank replacement cycle, reduced frequency of maintenance, reduced maintenance cost.
Alkaline hydrolysis tank for Rare Earth Production described in the utility model, comprise the alkaline hydrolysis tank, the coiling of alkaline hydrolysis tank outer side wall has the eddy current electric heater, it is characterized in that: be provided with in alkaline hydrolysis tank inside shape with it similar treat corrosion tank, treat that the corrosion tank external diameter is less than alkaline hydrolysis tank internal diameter, treat that the tank deck of corrosion tank links to each other with the tank deck of alkaline hydrolysis tank.
Wherein, the utility model considers that the degree of bottom corrosion wearing and tearing is about 2 times of tank body, thus described treat to be provided with in the corrosion tank add the deep-etching tank at the bottom of, add and be positioned at top at the bottom of the tank for the treatment of corrosion tank at the bottom of the deep-etching tank.
By said structure, formed the alkaline hydrolysis tank at the bottom of 2 layers of tank body and the 3 layers of tank.
Compared with prior art, the utlity model has following beneficial effect:
The alkaline hydrolysis tank that forms at the bottom of the 2 layers of tank body that adopts by the utility model and the 3 layers of tank; in use; when treating to be corroded adding of corrosion tank inside at the bottom of the deep-etching tank punch on is revealed, need not change, keep in repair; but continue to use; again the utility model is changed after all corroding at the bottom of the tank of wait corrosion tank; guaranteed like this to add taking full advantage of at the bottom of the deep-etching tank; and the eddy current electric heater played provide protection; prolonged the alkaline hydrolysis tank replacement cycle; reduce frequency of maintenance, reduced maintenance cost.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: 1, eddy current electric heater 2, alkaline hydrolysis tank 3, treat corrosion tank 4, add at the bottom of the deep-etching tank.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, the alkaline hydrolysis tank that is used for Rare Earth Production, comprise alkaline hydrolysis tank 2, the coiling of alkaline hydrolysis tank 2 outer side walls has eddy current electric heater 1, be provided with in alkaline hydrolysis tank 2 inside shape with it similar treat corrosion tank 3, treat that corrosion tank 3 external diameters are less than alkaline hydrolysis tank 2 internal diameters, treat that the tank deck of corrosion tank 3 links to each other with the tank deck of alkaline hydrolysis tank 2, treat to be provided with in the corrosion tank 3 and add at the bottom of the deep-etching tank 4, add at the bottom of the deep-etching tank 4 and be positioned at top at the bottom of the tank for the treatment of corrosion tank 3.
In use, when treating that adding at the bottom of the deep-etching tank of corrosion tank 3 inside 4 is corroded and need not changes, keep in repair when punch on is revealed, but continue to use, again the utility model is changed after all corroding at the bottom of the tank of wait corrosion tank 3, by the present embodiment, obtained good result of use, life cycle extended to about 11-12 month by original 3-4 month, approximately prolonged 3 times of times, upkeep cost reduces about 60% simultaneously, economizes on the use of funds annual approximately 250,000 yuan.
