[0027] Please refer to Figure 1 , Figure 2 and Figure 4 The external frame shell part 20 comprises an outer cylinder shell 210, a support 220 and a liquid outlet pipe 230. The outer cylinder shell 210 is located outside the cylinder of the lime digester main body 10, and the support 220 is fixed on the seat of the lime digester main body 10 to support the outer cylinder shell 210. The top end of the liquid outlet pipe 230 is in communication with the bottom of the outer cylinder shell 210. The spraying part 30 comprises a hood 310, a spraying head 320 and a conduit piece 330. The bottom of the hood 310 is in communication with one side of the middle part of the outer cylinder shell 210. The conduit piece 330 is arranged inside the hood 310, and a plurality of spraying heads 320 are arranged equidistantly inside the hood 310 and in communication with the conduit piece 330.

[0028] The lime slaker main body 10 adds cold water from the conduit 330 inlet port when producing and processing, and the cold water is finally sprayed on the surface of the lime slaker main body 10 through the conduit 330 and the shower head 320. The shower head 320 is arranged to be off-axis downward, and when spraying on one side of the cylinder, the rotating cylinder drives the surface part of the water stain to rotate, increasing the contact time of the cylinder and the water stain. The water stain in contact with the cylinder finally falls on the inside bottom of the outer cylinder shell 210, and the hot water is discharged from the outlet pipe 230 and utilized. The lime slaker can absorb the heat generated during the reaction and reduce the heat loss during the reaction.

[0029] Further, please refer to Figure 3 , the outer cylinder shell 210 is provided with a mounting port 260, and the cover shell 310 bottom end is arranged in communication with the mounting port 260.

[0030] In specific arrangement, please refer to Figure 2 and Figure 3 , the outer frame part 20 further includes a blocking plate 250, which is fixed to the inner wall of the outer cylinder shell 210 below the spraying part 30. The blocking plate 250 is used to block the water stain falling on the surface of the cylinder from falling on one side of the blocking plate 250. The water stain above the blocking plate 250 can be driven by the rotating cylinder to fall on the other side of the outer cylinder shell 210 inside the bottom, increasing the contact time of the water stain and the outer wall of the cylinder, improving the heat conduction time of the water stain, and collecting more heat. The blocking plate 250 is arranged with equidistantly distributed small holes 280 near the cylinder side wall of the lime slaker main body 10. Excess water stain on the blocking plate 250 can fall on the inside bottom of the outer cylinder shell 210 from the small holes 280.

[0031] Specifically, please refer to Figure 3 , the outer frame part 20 further includes a filter screen 270, which is arranged at the inside top end of the outlet pipe 230. The filter screen 270 can be used to filter impurities therein. The outer frame part 20 further includes a sealing ring 240, which is arranged at the end of the outer cylinder shell 210. The outer ring of the sealing ring 240 is provided with a groove, and the end of the outer cylinder shell 210 is clamped in the groove. The sealing ring 240 reduces the seepage of water stain from the gap between the outer cylinder shell 210 and the cylinder.

[0032] In specific arrangement, please refer to Figure 4 , the conduit 330 includes an inlet pipe 331 and a cross pipe 332, and the cross pipe 332 is arranged inside the cover shell 310. One end of the inlet pipe 331 is arranged in communication with the cross pipe 332, and the shower head 320 is arranged in communication with the lower part of the cross pipe 332.

[0033] The working principle of the lime slaking machine is as follows: when in use, the main body 10 of the lime slaking machine adds cold water from the liquid inlet port of the pipe member 330 during production and processing, the cold water is finally sprayed on the surface of the cylinder tank of the main body 10 of the lime slaking machine through the spray head 320, the spray head 320 is arranged to be eccentric to the axis, when spraying on one side of the cylinder tank, the rotating cylinder tank drives the water stains on the surface to rotate, thereby increasing the contact time of the cylinder tank and the water stains. The water stains in contact with the cylinder tank finally fall on the bottom side inside the outer cylinder shell 210, and the hot water is discharged from the liquid outlet pipe 230 and utilized. The lime slaking machine can absorb the heat generated during the reaction and use it, thereby reducing the heat loss during the reaction.

[0034] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. The present application can be variously changed and modified by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
