Description

Technical Field

[0002] A lime slaker, also known as a lime dissolving machine or lime slaker, is a specialized device that digests quicklime (calcium oxide) into lime milk or slaked lime powder. It is primarily used in industries such as steelmaking, chemical engineering, metallurgy, papermaking, power plant desulfurization, alumina, titanium dioxide, sugar production, biopharmaceuticals, and soda ash manufacturing. A lime slaker is a specialized device that digests quicklime into lime milk or lime powder. Conventional lime slakers typically incorporate a spray mechanism. This mechanism sprays water onto the quicklime within the slaker at a specified water flow rate. The spiral agitator then rotates, vigorously stirring the quicklime within the slaker, gradually dissolving, digesting, and slaking it. The agitator blades simultaneously propel the digested quicklime forward. However, existing lime slaker spray mechanisms present the following issues: The spray nozzles are typically fixed, limiting their spray range and resulting in uneven digestion of the quicklime within the slaker.
