Technical Field

[0001] This utility model relates to the field of phosphoric acid storage technology, specifically to a multi-layer phosphoric acid storage tank. Background Technology

[0002] Phosphoric acid is an important inorganic compound that can be used in the chemical field to make various chemical products. It can also remove metal ions such as calcium and magnesium from water to prevent scale formation. In the food industry, phosphoric acid can be used as a food additive, and in the agricultural field, it can be used to prepare phosphate fertilizers.

[0003] Phosphoric acid is mainly available in two concentrations: 85% and above, and 98% and above. The former is the standard concentration of experimental phosphoric acid, while the latter is industrial-grade phosphoric acid. Existing phosphoric acid storage tanks are generally single tanks that can only store one concentration of phosphoric acid at a time. When storing phosphoric acid of multiple concentrations, it is necessary to use separate storage tanks for different concentrations of phosphoric acid, which takes up too much space and is very inconvenient. Utility Model Content

[0004] Based on the above description, this utility model provides a multi-layer phosphoric acid storage tank to solve the problem that existing storage tanks can only store one concentration of phosphoric acid at a time.

Combined with a telescopic cylinder, the inner storage tank is stacked within the outer storage tank to form two storage spaces. Driven by the telescopic cylinder, the inner storage tank can move within the outer storage tank to adjust its height, controlling the distance between the two tanks and adjusting the available space within the inner storage tank. Two concentrations of phosphoric acid can be stored simultaneously in one container, reducing the number of containers required for storing multiple concentrations of phosphoric acid. The feeding pipe penetrating the inner side of the inner storage tank, along with a second through-hole, forms inner and outer ring openings. The inner ring opening is used for adding phosphoric acid to the outer storage tank, and the outer ring opening is used for adding phosphoric acid to the inner storage tank, without affecting the phosphoric acid feeding operation of the stacked containers.
