The invention discloses a multifunctional calcium hydroxide production device. The multifunctional calcium hydroxide production device comprises a reaction kettle, a feeding device, a water inlet pipe, a stirring grinder and a pressure relief valve, wherein the stirring grinder is inserted into a reaction kettle cavity from the center of the top of a reaction kettle; the feeding device and the water inlet pipe are inserted into the reaction kettle from opposite side walls close to the top of the reaction kettle; the pressure relief valve is mounted at one side of the top of the reaction kettle; the reaction kettle cavity is internally divided into a primary-grade reaction chamber and a secondary-grade reaction chamber from top to bottom; the primary-grade reaction chamber and the secondary-grade reaction chamber are separated by a filter screen welded on an inner wall surface of the reaction kettle; a grinding sieving screen is mounted on the bottom surface of the secondary-grade reaction chamber; a discharging hole is formed in the bottom surface of the grinding sieving screen; the stirring grinder penetrates through the filter screen and the bottom end of the stirring grinder is located above the grinding sieving screen. The multifunctional calcium hydroxide production device is simple in structure and reasonable in design; the pressure relief valve is designed so that the compression-resisting capability of the reaction kettle is reduced, and furthermore, the equipment cost is reduced; the reaction kettle with two grades of reaction chambers is designed, so that the yield of calcium hydroxide is improved and a production process is simplified.
Description
technical field [0001] The invention relates to the field of strong calcium oxide production equipment, in particular to a multifunctional calcium hydroxide production device. Background technique [0002] There are many types of calcium hydroxide production equipment and process methods, and the basic principle is to prepare calcium hydroxide by mixing quicklime and water. Since the reaction between quicklime and water is an exothermic reaction, a large amount of heat released during the process will inevitably increase the pressure in the reactor. The existing calcium hydroxide production equipment does not have a corresponding pressure relief device, and most of the heat generated during the reaction is consumed. , has not been utilized; in addition, calcium hydroxide needs multiple digestion and winnowing, takes up a lot of equipment, and the process is complicated. Contents of the invention [0003] The technical problem mainly solved by the present invention is to p...
