[0033] Please refer to Figures 1-4 , the mixing equipment for preparing solid waste-based high-performance autoclave-free PHC pipe pile cement, comprising:

[0034] The mixing tank 1 is used to load and mix the solid waste-based high-performance autoclave-free PHC pipe pile cement, and the mixing tank 1 is filled through the top filling port position, and the top can be cleaned by disassembly;

[0035] The stirring shaft 2 is arranged on the mixing tank 1 along the vertical axis of the mixing tank 1, and the lower end of the stirring shaft 2 extends from the bottom of the mixing tank 1;

[0036] The stirring blade structure is arranged at the lower end of the stirring shaft 2 to stir the solid waste-based high-performance autoclave-free PHC pipe pile cement loaded in the mixing tank 1, so that the solid waste-based high-performance autoclave-free PHC pipe pile cement is mixed, and the stirring blade structure rotates with the stirring shaft 2 to realize stirring;

[0037] The bottom material fishing mechanism is arranged on the stirring shaft 2 and moves up and down along the stirring shaft 2, and the bottom material is brought to the upper layer position during the lifting of the bottom material fishing mechanism; and

[0038] The lifting driving mechanism is arranged at the top of the mixing tank 1 to drive the bottom material fishing mechanism to move up and down.

[0039] Specifically, under the driving of the lifting driving mechanism, the bottom material fishing mechanism moves up and down, when the bottom material fishing mechanism descends to the bottom of the mixing tank 1, the material, especially the bottom material, is poured into the bottom material fishing mechanism, and then the bottom material fishing mechanism is lifted, and the lifting process moves the bottom material to the upper layer, thereby promoting the mixing effect of the material for preparing solid waste-based high-performance autoclave-free PHC pipe pile cement. When the bottom material fishing mechanism moves downward again, the above operation is repeated to bring the bottom material to the upper layer for mixing.

[0040] Further, the mixing tank 1 is a round bottom structure, so that the stirring blade structure can better stir the bottom material.

[0041] Further, the motor 3 is arranged at the bottom, and the motor 3 drives the stirring shaft 2 to rotate, wherein the electrical connection and use control of the electrical elements involved in the device are well known to those skilled in the art, and will not be described here.

[0042] Further, the stirring blade structure comprises a U-shaped stirring rod 4, the bottom of the U-shaped stirring rod 4 is an arc-shaped structure matched with the circular bottom of the stirring tank 1 with a round bottom structure, the two sides are vertical rod-shaped structures vertically extending from the two ends of the arc-shaped structure, the center position of the arc-shaped structure of the U-shaped stirring rod 4 is connected with the bottom of the stirring shaft 2 to rotate with the stirring shaft 2. The U-shaped stirring rod 4 corresponding to the bottom of the arc-shaped structure can be closer to the solid waste-based high-performance autoclaved PHC pile cement material on the circular bottom of the stirring tank 1 to stir, thereby improving the stirring effect. Similarly, the U-shaped stirring rod 4 of the vertical rod-shaped structure on the two sides is close to the side wall of the stirring tank 1 for stirring, while avoiding the bottom material fetching mechanism.

[0043] Further, the vertical rod-shaped structure position of the U-shaped stirring rod 4 is connected with multiple supporting rods 5 on the side facing the center position of the stirring tank 1 and the inner side of the arc-shaped structure position. The supporting rods 5 extend to the center position of the stirring tank 1 to increase the stirring effect.

[0044] Further, the vertical rod-shaped structure on the two sides of the U-shaped stirring rod 4 is located on the two sides of the bottom material fetching mechanism to avoid the bottom material fetching mechanism.

[0045] Further, the bottom material fetching mechanism comprises a sleeve 6 sleeved on the stirring shaft 2 and sliding along the axial direction of the stirring shaft 2, multiple fetching plates 7 are arranged on the outer surface of the sleeve 6 and uniformly distributed in the circumferential direction, so that a sufficient amount of deposited material can be fetched each time the sleeve 6 is lowered. One end of the fetching plate 7 is connected to the sleeve 6 and extends upward at an inclined angle, and a leakage hole 8 is formed in the end portion of the fetching plate 7 close to the sleeve 6. During the upward movement of the fetching plate 7, the bottom material on the fetching plate 7 can slide downward along the inclined fetching plate 7, and the material continuously leaks out of the leakage hole 8 during the sliding of the fetching plate 7, thereby achieving a better dispersion effect and the same effect as stirring. The lifting movement of the fetching plate 7 also stirs the material in the middle part of the stirring tank 1, which cooperates with the stirring blade structure to achieve a better stirring effect.

[0046] Further, the cross section of the fetching plate 7 is V-shaped to better hold the deposited material and bring it upward.

[0047] Further, the lifting driving mechanism comprises a guide rod 9 connected to the top of the sleeve 6 in a vertical state, the guide rod 9 is symmetrically arranged in two groups on the two sides of the top of the sleeve 6, a guide hole 10 is formed in the top surface of the stirring tank 1 to allow the upper end of the guide rod 9 to extend out, the number of guide holes 10 is two groups and corresponds to the two groups of guide rods 9, the guide rod 9 slides in the guide hole 10, and the top position between the two groups of guide rods 9 and outside the stirring tank 1 is connected with a top plate 11.

[0048] A stand 12 is arranged on the top surface of the stirring tank 1, and a telescopic cylinder 13 is arranged on the stand 12, and the telescopic end of the telescopic cylinder 13 is connected with the top plate 11.

[0049] Specifically, the telescopic cylinder 13 supported by the stand 12 drives the top plate 11 to move up and down through the telescopic end, and then drives the guide rod 9 to move up and down, and in this process, the guide rod 9 slides in the guide hole 10 to drive the sleeve 6 to slide axially along the stirring shaft 2 to drive the bailing plate 7 to move up and down. In this process, the sleeve 6 cannot rotate under the support of the guide rod 9, but can slide axially along the stirring shaft 2, so the rotation of the stirring shaft 2 does not affect the up-down movement of the sleeve 6.

[0050] Further, the upper and lower ends of the stirring shaft 2 are rotatably connected with the stirring tank 1 through bearings, specifically, the lower end of the stirring shaft 2 can be rotatably connected with the stirring tank 1 through a rotary sealing ring to realize sealing and rotation at the same time, but in order to strengthen the support stability of the lower end of the stirring shaft 2, a bearing seat and a bearing can also be arranged at the bottom of the stirring tank 1 to support the lower end of the stirring shaft 2. In addition, the upper end of the stirring shaft 2 can be connected with the top of the stirring tank 1 through a bearing that can be disassembled at any time, or can be supported through the same bearing structure as the bottom of the stirring tank 1.

[0051] In summary, in the process of stirring the preparation materials of the solid waste-based high-performance autoclave-free PHC pipe pile cement, the solid waste materials at the bottom of the stirring device are bailed to the upper position for stirring through the continuous work of the bottom material bailing mechanism, so that the phenomenon of uneven stirring caused by the stratification of different materials due to different densities is avoided, and the preparation quality of the solid waste-based high-performance autoclave-free PHC pipe pile cement is ensured.

[0052] The above only describes some exemplary embodiments of the present application by way of illustration, without doubt, for ordinary skilled in the art, without departing from the spirit and scope of the present application, the described embodiments can be modified in various ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection claimed by the present application.
