An outer cylinder 3 is arranged on the outer side of the inner cylinder 1. A heat-insulating layer 4 is arranged between the inner cylinder 1 and the outer cylinder 3. A water-adding cylinder 5 and a material-adding cylinder 6 are respectively arranged on the outer side of the outer cylinder 3. One end of the water-adding cylinder 5 and the material-adding cylinder 6 both extend into the inner cylinder 1. A mounting cover plate 7 is detachably provided on the top of the inner cylinder 1. A driving assembly 8 is vertically provided in the middle of the mounting cover plate 7. A plurality of stirring rods 9 are vertically provided on the driving assembly 8. A pressing plate 10 is provided on the top of the plurality of stirring rods 9. A telescopic cylinder 11 for driving the pressing plate 10 is provided on the mounting cover plate 7. The energy storage tank 2 is sealed in the middle of the outer cylinder 3, and the energy storage tank 2 is communicated with the inner cylinder 1.

[0025] It should be noted that a control box for controlling the drive assembly 8 and the telescopic cylinder 11 is provided on the outer tube 3, and a temperature gauge and a pressure gauge for monitoring the internal temperature and pressure of the inner tube 1 are provided on the outer tube 3, thereby improving safety.

[0026] In this embodiment: the driving component 8 drives the stirring rod 9 to stir the quicklime at the bottom of the inner tube 1, thereby increasing the reaction area between the quicklime and the liquid water. At the same time, the telescopic cylinder 11 is used to drive the pressing plate 10 to descend and compress the gas inside the inner tube 1, thereby ensuring stable and efficient discharge of the cement slurry. In addition, when the pressing plate 10 descends, the inner wall of the inner tube 1 and the outer wall of the stirring rod 9 can be cleaned to avoid the residue of cement slurry.

[0027] In an optional embodiment, an electromagnetic control valve 12 is provided in the middle of the water adding cylinder 5 and the material adding cylinder 6, and a discharge pipe 13 is provided at the bottom of the inner cylinder 1.

[0028] In this embodiment, the discharge pipe 13 is opened manually, and the addition ratio of liquid water and quicklime can be controlled by setting the opening time of the electromagnetic control valve 12, thereby ensuring the mixing effect.

[0029] like Figure 3 As shown;

[0030] In an optional embodiment, the driving assembly 8 includes a driving motor 801, and the output end of the driving motor 801 is provided with a driving rod 802 extending to the bottom of the inner cylinder 1, and the bottom and top of the driving rod 802 are respectively provided with a mounting frame 803 and a mounting ring 804, and a stirring rod 9 is detachably provided between the mounting frame 803 and the mounting ring 804.

The stirring rod 9 can be fixed to the mounting frame 803 and the mounting ring 804 by means of a screw connection, so as to facilitate disassembly and replacement.

[0032] like Figure 4 As shown;

[0033] In an optional embodiment, a receiving groove 14 is provided in the middle of the pressure plate 10 , and a compression spring 15 extending to the top of the mounting bracket 803 is provided inside the receiving groove 14 .

[0034] In this embodiment: the accommodating groove 14 is used to accommodate the compression spring 15, so that the pressure plate 10 can be compressed to abut against the bottom of the inner tube 1, thereby ensuring that the cement slurry is discharged more thoroughly and efficiently; the compression spring 15 can drive the pressure plate 10 to quickly reset after the telescopic cylinder 11 contracts.

[0035] In an optional embodiment, the output end of the telescopic cylinder 11 is provided with an extrusion ring 16 that abuts against the top end of the pressing plate 10 .

[0039] It should be noted that the sealing ring 17 is made of high temperature resistant material, and the inner diameter of the top of the inner cylinder 1 can be set to be larger than the outer diameter of the sealing ring 17, so as to avoid continuous friction between the sealing ring 17 and the inner wall of the inner cylinder 1 when the pressure plate 10 rotates, thereby increasing the service life of the sealing ring 17.

[0040] The working principle and use process of the utility model are as follows: liquid water and quicklime are respectively put into the water adding cylinder 5 and the feeding cylinder 6, and the liquid water and quicklime can be injected into the inner cylinder 1 by starting the electromagnetic control valve 12, and the driving motor 801 is started at the same time, and the driving motor 801 drives the mounting frame 803 and the stirring rod 9 to rotate, so as to stir the liquid water and quicklime, and the liquid water and quicklime react to generate cement slurry and discharge the generated heat into the energy storage tank 2 for collection; when it is necessary to discharge, the discharge pipe 13 is opened and the telescopic cylinder 11 is started, the telescopic cylinder 11 is extended and the pressing plate 10 is squeezed by the extrusion ring 16, the pressing plate 10 descends and compresses the gas inside the inner cylinder 1, so as to ensure the stable and efficient discharge of the cement slurry, and at the same time, the inner wall of the inner cylinder 1 and the outer wall of the stirring rod 9 can be cleaned when the pressing plate 10 descends, so as to avoid the residue of cement slurry.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
