Description

Technical Field

[0001] The utility model belongs to the field of baking soda production, and specifically relates to a series slurry mixing device. Background Art

[0002] The slurry mixer is the first and most important step in the production process of baking soda by wet decomposition. The main raw material wet heavy alkali required for the production of baking soda in our factory is carbonized in the alkali plant and conveyed to the slurry mixer via a belt for alkali treatment.

[0003] The existing process is that the heavy alkali comes from the joint alkali plant and enters the two slurry mixers A and C. After the heavy alkali is internalized in the two slurry mixers A and C, the solution enters the two slurry mixers B and D respectively. Two sets of slurry pumps respectively pump the mother liquor from the two slurry mixers B and D into the wet decomposition tower.

[0004] In the wet decomposition production process, two sets of slurry preparation systems require two sets of slurry pumps to fully operate to deliver liquid when producing at full capacity. Adding two slurry pumps will increase power consumption and labor costs. The uneven addition of alkali in the two sets of slurry preparation systems will also cause large fluctuations in wet decomposition operations, affecting indicators.

[0005] Therefore, we propose a series slurry adjustment device to solve the above problems. Utility Model Content

[0006] In view of the problem that in the wet decomposition production process, two sets of slurry mixing systems need two sets of slurry pumps to fully operate to deliver liquid when in full load production, adding two slurry pumps will increase power consumption and labor costs. The two sets of slurry mixers will also cause large fluctuations in wet decomposition operation due to uneven alkali addition, which will affect indicators. The utility model provides a series slurry mixing device.
