Technical Field

[0002] Quicklime reacts with water in the digester to produce slaked lime. Slaked lime has a large reaction surface area, which is very beneficial for improving the reaction efficiency of slaked lime in related applications. However, the slaked lime generated in the digester tends to agglomerate into larger agglomerates after contacting water, which will reduce the effective surface area of the slaked lime and is not conducive to the contact and reaction between the slaked lime and other substances. In order to restore the high specific surface area characteristics of slaked lime, it is necessary to disperse the agglomerated slaked lime so that large agglomerates are dispersed into small particles to ensure the performance of the slaked lime. At present, the deagglomeration machines on the market generally send the agglomerated slaked lime into the deagglomeration chamber for deagglomeration, and the deagglomerated slaked lime enters the next level separation device for screening and separation. The slaked lime that meets the requirements is collected, and the slaked lime that does not meet the requirements re-enters the deagglomeration chamber for deagglomeration.

[0014] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.
[0015] like Figure 1 , Figure 2 As shown, the agglomerated slaked lime deagglomeration dryer of the utility model comprises: a deagglomeration chamber 1, a maintenance hole is opened on the side wall of the deagglomeration chamber 1, a maintenance door 11 is arranged on the maintenance hole, a rotating shaft 12 is arranged in the deagglomeration chamber 1 for sealing and rotation, a plurality of deagglomeration parts are arranged on the rotating shaft 12 along the axial direction, two deagglomeration sticks 13 are symmetrically arranged in each deagglomeration part, the deagglomeration sticks 13 in each two adjacent deagglomeration parts are staggered, and the connection structure between the deagglomeration stick 13 and the rotating shaft 12 is as follows: a screw hole is arranged on the rotating shaft 12, a threaded section is arranged on the deagglomeration stick 13, the threaded section on the deagglomeration stick 13 is threadedly connected to the screw hole on the rotating shaft 12, a locking nut 131 is threadedly connected to the threaded section of the deagglomeration stick 13, and the locking nut 131 is screwed It is screwed against the rotating shaft 12, and the rotating shaft 12 is connected to the reduction motor 2 after extending out of the depolymerization chamber 1. The connection structure between the rotating shaft 12 and the reduction motor 2 is as follows: a first sprocket 121 is arranged on the rotating shaft 12, and a second sprocket 21 with the same diameter and number of teeth as the first sprocket 121 is arranged on the output shaft of the reduction motor 2, and a double-row chain 22 is wound around the first sprocket 121 and the second sprocket 21. Since the rotating shaft 12 needs to disperse the agglomerated slaked lime in the depolymerization chamber 1 through the depolymerization roller 13, the rotating shaft 12 needs to be in a low-speed and heavy-load transmission environment. Compared with the coupling, the use of the double-row chain 22 can form a flexible connection between the rotating shaft 12 and the reduction motor 2, which has the functions of buffering, vibration reduction and improving the working characteristics of the transmission system.
[0016] A feed inlet 14 and a discharge outlet 15 are provided on the top wall of the depolymerization chamber 1, and a cyclone filter cartridge pulse collector 3 is provided on the discharge outlet 15. The feed inlet 14 is located directly above the rotating shaft 12. A metal fluidizing cloth 4 is laid in the depolymerization chamber 1 located below the rotating shaft 12. The metal fluidizing cloth 4 is a metal sintered wire mesh with a filtration accuracy of 0.1 mm to 0.25 mm. The filtration accuracy of 0.1 mm to 0.25 mm can prevent the depolymerized slaked lime powder from falling out, and the metal sintered wire mesh is resistant to high temperature and has high strength. The metal fluidizing cloth 4 located on both sides of the rotating shaft 12 is connected to the depolymerization chamber 1 upward, and the metal fluidizing cloth 4 located on both sides of the rotating shaft 12 is connected to the depolymerization chamber 1 upward. The metal fluidizing cloth 4 directly below the rotating shaft 12 is recessed downward, and the deagglomeration roller 13 can disperse the slaked lime accumulated on the bottom and sides of the recessed part of the metal fluidizing cloth 4 when rotating, thereby improving the dispersing efficiency of the deagglomeration roller 13 on the rotating shaft 12 on the slaked lime accumulated on the metal fluidizing cloth 4. A plurality of fluidizing air pipes 5 are arranged on the bottom wall of the deagglomeration chamber 1, and each fluidizing air pipe 5 is connected to an air drying and heating assembly through the same distribution pipe. The air drying and heating assembly is a prior art and will not be described in detail herein. The air drying and heating assembly is connected to a compressed air source, and heating tapes are wound around the fluidizing air pipe 5 and the distribution pipe.
[0017] When in use, the cyclone filter cartridge pulse collector 3 on the discharge port 15 is opened, and the cyclone filter cartridge pulse collector 3 generates an upward suction force on the depolymerization chamber 1, and the agglomerated slaked lime is sent from the feed port 14 to the depolymerization chamber 1. Since the agglomerated slaked lime has a heavier particle size, the suction force generated by the cyclone filter cartridge pulse collector 3 is insufficient to suck it into the discharge port 15, and the agglomerated slaked lime will accumulate on the metal fluidized cloth 4. Since the metal fluidized cloth 4 is in a state of high ends and low middle, the agglomerated slaked lime will accumulate under the action of gravity. The deagglomeration roller 13 on the rotating shaft 12 disperses the agglomerated slaked lime, and at the same time, the compressed air source and the air drying and heating component are turned on. The compressed air is heated by the air drying and heating component to form hot dry air with a relatively high temperature. The hot dry air enters each fluidizing air pipe 5 through a distribution pipe. The heating belts on the fluidizing air pipe 5 and the distribution pipe can keep the hot dry air in the fluidizing air pipe 5 and the distribution pipe warm. The hot dry air in the fluidizing air pipe 5 is sprayed upward to the gold The slaked lime on the metal fluidizing cloth 4 is fluidized. The slaked lime moves relative to the dry hot air under the action of gravity. The drying speed of the slaked lime is accelerated by the heat and mass transfer principle. Under the dispersing action of the deagglomeration roller 13, the agglomerated slaked lime is broken into smaller blocks or directly broken into powder, increasing the contact area with the dry hot air and further improving the drying speed of the slaked lime. After the slaked lime is dried, it forms a granular fluidized state under the action of the dry hot air. At this time, the particles of the slaked lime in the granular fluidized state are The particle size specific gravity is relatively light, and it is easy to be affected by the suction of the cyclone filter cartridge pulse collector 3 and enter the cyclone filter cartridge pulse collector 3 through the discharge port 15 for collection. The particle size specific gravity of the slaked lime that is not completely in a granular fluidized state is relatively heavy, and it cannot be affected by the suction of the cyclone filter cartridge pulse collector 3 and enter the discharge port 15. The slaked lime with a relatively heavy particle size specific gravity will roll to the depression of the metal fluidizing cloth 4 under the action of its own weight and contact with the rotating deagglomeration roller 13, and will continue to be dispersed and dried by the rotating deagglomeration roller 13 and the dry hot air.

Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or replaced by equivalents, and any modification or equivalent replacement that does not depart from the spirit and scope of the utility model should be included in the scope of protection of the claims of the utility model.
