DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] See also Figure 1-4 The utility model provides the following technical solutions: a closed hazardous waste cement solidification device, including a base 1, two support frames 2 are correspondingly installed on the top of the base 1, a mixing barrel 3 is arranged between the two support frames 2, the inner side walls of the two support frames 2 are rotatably connected with a connecting frame 4, and the ends of the connecting frame 4 are connected to the two ends of the mixing barrel 3, a servo motor 5 is installed on the outer side wall of one of the support frames 2, a feeding end 6 is connected to one side of the top of the mixing barrel 3, a first solenoid valve 8 is installed on the surface of the feeding end 6, a discharging end 7 is connected to one side of the bottom end of the mixing barrel 3, a second solenoid valve 9 is installed on the surface of the discharging end 7, a stirring rod 10 is arranged inside the mixing barrel 3, one end of the stirring rod 10 is connected to a bearing 11, and one end of the mixing barrel 3 is connected to a driving motor 17.

[0024] Preferably, the output shaft of the servo motor 5 is connected to the outer side wall of the connecting frame 4 , and the mixing barrel 3 is rotatably connected to the supporting frame 2 via the connecting frame 4 .

[0025] Preferably, the output shaft of the driving motor 17 is connected to one end of the stirring rod 10 , and the stirring rod 10 is rotationally connected to the stirring barrel 3 via a bearing 11 .

[0026] Preferably, the drive motor 17 and the servo motor 5 have opposite axial rotations.

[0027] In the embodiment, when the hazardous waste closed cement solidification device is working, the power supply is connected to start the drive motor 17 and the servo motor 5 respectively. At this time, the drive motor 17 drives the stirring rod 10 to rotate counterclockwise inside the stirring barrel 3 along the inner ring of the bearing 11, and the servo motor 5 drives the connecting frame 4 to rotate clockwise, and the stirring barrel 3 connected to the end of the connecting frame 4 rotates accordingly, thereby forming a clockwise rotation of the stirring barrel 3 and a counterclockwise rotation of the stirring rod 10 inside the stirring barrel 3, and then the rotation in two directions allows the hazardous waste and cement inside the stirring barrel 3 to be turned over, thereby reducing the mixing dead angle, improving the mixing efficiency, and increasing the mixing effect.

[0028] It should be noted that hazardous waste and cement can be fed into the mixing barrel 3 from the feed end 6, and can be discharged to the outside from the discharge end 7 after mixing. The first solenoid valve 8 and the second solenoid valve 9 can respectively seal the openings of the feed end 6 and the discharge end 7, so that the mixing barrel 3 is in a closed state for mixing.

[0029] Embodiment 2

[0030] See also Figure 1-4 Two fixed blocks 13 are installed at the top of the base 1, and an impact block 16 is set at the top of the fixed block 13.

[0032] In the embodiment, according to the description of the first embodiment, during the clockwise rotation of the mixing barrel 3, the extrusion block 12 will be driven to perform the same rotational motion, and then as the mixing barrel 3 moves, the extrusion block 12 will contact the impact block 16. At the same time, since the contact angle between the extrusion block 12 and the impact block 16 is an arc, it can be referred to Figure 2 and 4 , and then the extrusion block 12 will squeeze the impact block 16 to shrink, and at the same time the spring 14 will also be forced to shrink and deform, and then the impact block 16 will drop a certain distance through the extrusion block 12, and then when the extrusion block 12 is released from the extrusion of the impact block 16, it will rebound through the elasticity of the spring 14 and then hit the outer wall of the mixing barrel 3, so that the shock generated by the impact is transmitted to the inner wall of the mixing barrel 3, thereby shaking off the hazardous waste and cement adsorbed on the inner wall of the mixing barrel 3.

[0033] In summary, according to the description of Examples 1 and 2, the use of the closed hazardous waste cement solidification device not only improves the stirring efficiency, but also increases the mixing effect, further reducing the situation of hazardous waste and cement adhering to the inner wall, thereby improving the practicality of the closed hazardous waste cement solidification device.
