Two groups of positioning nuts and a movable pipe are respectively sleeved on the surface of each annular thread groove. The two positioning nuts are respectively attached to the upper surface and the lower surface of the movable pipe. Guide blocks are arranged at the positions corresponding to the guide grooves on the inner side of the movable pipe, and the guide blocks are movably arranged inside the guide grooves. The mixing blades are arranged on the side surface of the movable pipe.

[0008] In the upper half of the tank body, a pressure regulating assembly is provided. The pressure regulating assembly includes a telescopic member and a piston plate.

The external frame 2 is a square frame, and the external frame 2 is movably sleeved on the surface of the tank body 1. The tank body 1 is located in the middle position of the placement frame to improve the stability of the tank body 1. A fixing plate 3 is arranged on the surface of the tank body 1. The fixing plate 3 is a horizontal plate. A sliding groove 4 is opened on the inner wall of the external frame 2 at the position corresponding to the fixing plate 3. The fixing plate 3 slides inside the sliding groove 4. The number of the sliding grooves 4 is two groups. The two groups of sliding grooves 4 are symmetrically arranged with the horizontal symmetry axis of the tank body 1 as the axis of symmetry. The number and position of the fixing plates 3 match the number and position of the sliding grooves 4. The two groups of fixing plates 3 both slide in the two groups of sliding grooves 4. The inner walls of the fixing plates 3 and the sliding grooves 4 are both smooth, so as to reduce the frictional resistance of the movement. A reciprocating driving rod 6 is arranged on the surface of the push plate 5 on the horizontal symmetry axis of the tank body 1. When the reciprocating driving rod 6 moves, the whole tank body 1 is evenly stressed through the push plate 5. A push plate 5 is fixed on the fixing plate 3. A reciprocating driving rod 6 is arranged on the side of the push plate 5 away from the tank body 1. An active driving rod 7 is movably arranged on the reciprocating driving rod 6. A turntable 8 is arranged at one end of the active driving rod 7. A first driving motor 9 is fixed on the turntable 8. The first driving motor 9 is fixed inside the external frame 2. Support columns 10 are arranged at the bottom of the external frame 2. The external frame 2 stably places the tank body 1 on the ground through the support columns 10. During operation, when the materials in the tank body 1 are mixed, the first driving motor 9 is started. The first driving motor 9 drives the turntable 8 to rotate. When the turntable 8 rotates, it drives the active driving rod 7 to rotate. When the active driving rod 7 rotates, it drives the reciprocating driving rod 6 to reciprocate horizontally. When the reciprocating driving rod 6 reciprocates horizontally, it drives the push plate 5 to reciprocate. When the push plate 5 reciprocates, it will drive the fixing plate 3 to slide inside the sliding groove 4. In this way, when the fixing plate 3 slides, it will drive the tank body 1 to reciprocate horizontally. When the tank body 1 reciprocates horizontally, it drives the materials inside to shake, making the materials inside not easy to precipitate, and at the same time, the shaking of the materials increases the mixing efficiency of the materials;

[0024] An inlet pipe 11 and an outlet pipe 12 are arranged on the side of the tank body 1. The inlet pipe 11 is located above the outlet pipe 12. The materials inside the tank body 1 enter the inside of the tank body 1 through the inlet pipe 11, and the mixed materials are discharged through the outlet pipe 12.

[0025] Embodiment 2

The mixing component 13 includes a mixing rod 14 and mixing blades 15. The materials are mixed by the rotation of the mixing blades 15. The bottom end of the mixing rod 14 is rotatably connected to the tank body 1, and the bottom end of the mixing rod 14 passes through the tank body 1 and extends to the bottom end of the tank body 1. A transmission gear 16 is fixedly sleeved on the surface of the mixing rod 14 extending outside the tank body 1.

A guide groove 20 is formed inside each annular thread groove 19. Two groups of positioning nuts 21 and a movable pipe 22 are respectively sleeved on the surface of each annular thread groove 19. The two groups of positioning nuts 21 are threadedly connected to the annular thread groove 19, and the movable pipe 22 is movably sleeved on the surface of the annular thread groove 19 without threaded connection. The two positioning nuts 21 are respectively attached to the upper surface and the lower surface of the movable pipe 22. A guide block 23 is arranged on the inner side of the movable pipe 22 corresponding to the position of the guide groove 20, so that the movable pipe 22 can only move along the mixing rod 14 inside the annular thread groove 19 and cannot rotate itself. The guide block 23 moves inside the guide groove 20. The mixing blades 15 are arranged on the side surface of the movable pipe 22. During adjustment, the two groups of positioning nuts 21 are rotated to make the positioning nuts 21 move away from the movable pipe 22, and then the position of the movable pipe 22 is moved up and down. The change of the position of the movable pipe 22 will drive the change of the position of the mixing blades 15. After the position of the mixing blades 15 is adjusted, the two groups of positioning nuts 21 are rotated in the reverse direction to make the two groups of positioning nuts 21 fit on the two end faces of the movable pipe 22 to limit the movable pipe 22. In this way, the position of the mixing blades 15 can be finely adjusted, and the position of the mixing blades 15 is adjusted to improve the mixing performance of the mixing blades 15.

During operation, controlling the telescopic member 25 to extend will push the piston plate 26 to move downward inside the tank body 1, which will reduce the internal space of the tank body 1 to increase the internal pressure of the tank body 1, thus avoiding pressurizing the tank body 1 from the external conveying space, reducing operations such as filtering the external air, and also avoiding the influence on the mixing efficiency due to the mismatch between the temperature of the external air and the temperature inside the tank body 1. A pressure detection gauge 31 is provided at the position on the surface of the tank body 1 between the inlet pipe 11 and the outlet pipe 12. During pressurization, the internal pressurization situation of the tank body 1 can be observed in real time through the pressure detection gauge 31;

It should be noted that in this embodiment, one end of the rod body 28 is movably provided with a telescopic rod 30, and the telescopic rod 30 is rotatably connected to the piston plate 26 through a bearing, which improves the stability of the rod body 28 during mixing and does not affect the normal operation of the rod body 28. When the piston plate 26 is pressed down, it will drive the telescopic rod 30 to move downward. The telescopic rod 30 moves downward inside the telescopic hole 29, thus shortening the length of the entire mixing rod 14 to avoid the position of the piston plate 26.
