Description
Technical Field
[0001] The present invention relates to the technical field of foaming and stirring, and in particular to a stirring device for preparing chemically foamed foam concrete. Background Art
[0002] Foam concrete, also known as foamed concrete or lightweight concrete, is prepared by mechanically foaming a foaming agent through the foaming system of a foaming machine, uniformly mixing the foam with a cement slurry, and then performing in-situ construction or mold forming through the pumping system of the foaming machine. The preparation of foam concrete is to first prepare an aqueous solution of the foaming agent into foam, and then add the foam to a slurry composed of siliceous materials, calcareous materials, water, and various additives for stirring. However, there are usually the following problems in this mixing and stirring: First, during the mixing process, the foam and the concrete may not be fully mixed, that is, the foam is unevenly distributed in the concrete, resulting in the phenomenon that there is no foam in some areas of the concrete while there is too much foam in the remaining areas. This will lead to the failure of making foamed concrete. Secondly, the size of the bubbles in the foamed concrete also needs to be regulated during the manufacturing process, and it also needs to be timely regulated according to different requirements, that is, the ratio of the concrete to the bubbles is adjusted. However, the existing adjusting devices are usually extremely complex, and it is difficult to change the bubble situation in the foamed concrete in real time by generally using chemical reagents.
[0003] Therefore, we have designed a stirring device for preparing chemically foamed foam concrete. Summary of the Invention

[0008] Preferably, the storage tank is annularly fixed on the inner wall of the main body of the stirring tank. An inner cavity is opened on the storage tank.

Detailed implementation manners
[0019] Refer to Figures 1 - 10, A stirring device for preparing chemically foamed foam concrete, including a stirring tank body 1. A driving motor 2 is provided at the bottom of the stirring tank body 1. A plurality of stirring parts 6 for stirring the concrete in the stirring tank body 1 are arranged in the stirring tank body 1. The output end of the driving motor 2 is fixed with a rotating shaft extending into the stirring tank body 1, and the stirring parts 6 are coaxially fixed on the rotating shaft. Therefore, after the driving motor 2 is started, the rotating shaft extending into the stirring tank body 1 will rotate, and then the concrete inside the stirring tank body 1 will be driven to stir.
[0020] A feed pipe 13 is provided on the outer side wall of the stirring tank body 1, and transverse plate boxes 3 are symmetrically provided on the side wall of the stirring tank body 1. And the baffle plate 5 slides horizontally in the transverse plate box 3 through the sliding cavity 4. Semi-holes adapted to the extrusion pipe 7 are opened at the opposite ends of the two baffle plates 5. Baffle plates 5 for separating the stirring tank body 1 are symmetrically provided on the side wall of the stirring tank body 1. It should be noted that the baffle plate 5 slides in the sliding cavity 4 through an externally provided electric pushing mechanism for separating the stirring tank body 1. The lower part of the baffle plate 5 is the stirring area, and the upper part of the baffle plate 5 is the extrusion accommodating area, that is, the mixture of foam and concrete is conveyed above the baffle plate 5.
[0021] The top of the rotating shaft is fixed with a batching tank body 11, and a plurality of rotating pipes 15 connected to the inner wall of the stirring tank body 1 are circumferentially inserted on the outer side wall of the batching tank body 11. Refer to Figure 2 State, a meshing gear 19 is fixed on the outer side wall of the rotating pipe 15 extending into the inner cavity 18, and an annular toothed plate meshing with the meshing gear 19 is provided at the bottom of the inner cavity 18. Therefore, when the driving motor 2 drives the rotating shaft to rotate, it drives the batching tank body 11 and a plurality of rotating pipes 15 on the side to rotate together. In this way, the rotating pipe 15 slides in the inner cavity 18, and the meshing gear 19 meshes with the annular toothed plate, so the rotating pipe 15 will be driven to rotate.
[0022] It should be noted that a plurality of stirring row rods 16 for stirring the concrete are fixed on the outer side wall of the rotating pipe 15. Refer to Figure 1 And Figure 2 State, a plurality of stirring row rods 16 are circumferentially fixed on the outer side wall of the rotating pipe 15. A plurality of through slots are opened on the stirring row rods 16, and the through slots are arc-shaped. The stirring row rods 16 on adjacent two rotating pipes 15 are arranged in a staggered manner. In this way, during the rotation of the rotating pipe 15, a plurality of stirring row rods 16 on the side wall will be driven to rotate, and the through slots of the stirring row rods 16 on the two rotating pipes 15 will pass through, so that the rotation of the rotating pipe 15 will not be blocked.
[0023] This setting will cause the concrete flowing into the stirring tank body 1 from the feed pipe 13 to be stirred for the first time, so that the air bubbles originally existing in the concrete can be removed, ensuring that the air bubbles in the concrete flowing to the lower part after passing through the stirring row rods 16 are removed cleanly, which is convenient for subsequent operations.
[0024] Reference Figure 4 In the state, the stirring part 6 includes a base 61, the base 61 is coaxially fixed on the rotating shaft, a plurality of guide pipes 14 are inserted through the plurality of bases 61, and the guide pipes 14 are communicated with the main body 11 of the batching box. The guide pipes 14 are connected to the base 61 through communication holes 62, so that the concrete is introduced into the main body 11 of the batching box through the guide pipes 14.
[0025] The stirring part 6 further includes stirring fan blades 63. A plurality of stirring fan blades 63 are provided, and the plurality of stirring fan blades 63 are circumferentially fixed on the outer side wall of the base 61. A plurality of feeding strip holes 64 are formed on one side of the stirring fan blades 63 facing the bottom of the stirring box main body 1, and the feeding strip holes 64 are communicated with the guide pipes 14. Therefore, when the stirring part 6 rotates, the stirring fan blades 63 will rotate, and the concrete will be pushed by the feeding strip holes 64, so that the concrete is continuously squeezed into the guide pipes 14. In this way, the stirring fan blades 63 can not only play the role of stirring the concrete, but also squeeze the concrete into the guide pipes 14.
[0026] A foaming machine for introducing foam into the inner cavity 18 is fixed on the outer side wall of the stirring box main body 1. Therefore, the foam is introduced into the inner cavity 18 to facilitate the mixing of the foam and the concrete. A storage box 17 is fixed on the inner wall of the stirring box main body 1, and the rotating pipe 15 is inserted into the storage box 17. The storage box 17 is annularly fixed on the inner wall of the stirring box main body 1. An inner cavity 18 is formed on the storage box 17. A rotating blocking ring 33 for blocking the inner cavity 18 is rotatably provided on one side of the storage box 17 facing the batching box main body 11. One end of the rotating pipe 15 penetrates through the rotating blocking ring 33 and extends into the inner cavity 18, and the other end of the rotating pipe 15 extends into the batching box main body 11. Therefore, the foam introduced into the inner cavity 18 will enter the batching box main body 11 through the rotating pipe 15.
[0027] Reference Figures 5 - 8 In the state, a foam introduction part for introducing foam into the concrete is provided in the batching box main body 11. An internal baffle 12 is provided in the batching box main body 11. The internal baffle 12 is used to divide the batching box main body 11 into an upper chamber and a lower chamber. A communication ring 20 is provided on the upper chamber, and the lower chamber is communicated with the extrusion pipe 7 through the communication ring 20; It should be noted that the foam introduced through the rotating pipe 15 enters the upper chamber, while the concrete enters the lower chamber, and both the foam and the concrete enter the extrusion pipe 7 through the communication ring 20.
[0028] The foam introduction part is arranged in the upper chamber, and the rotating pipe 15 is connected to the foam introduction part, and the foam introduction part extends into the connecting ring 20. The foam introduction part includes a rotating disk 27, which is coaxially fixed on the outer side wall of the rotating pipe 15. A plurality of sliding holes 28 are circumferentially formed on the rotating disk 27. On the side of the rotating disk 27 facing the abutting rod 23, triangular blocks 29 corresponding to the sliding holes 28 one by one are circumferentially arranged. Therefore, the rotation of the rotating pipe 15 will drive the rotating disk 27 to rotate together. It should be noted that by adjusting the rotation speed of the driving motor 2, the faster the rotation speed of the rotating shaft, the faster the rotation speed of the rotating pipe 15 will be.
[0029] The triangular block 29 slides radially on the sliding hole 28 through the fixing block 30. A second return spring 31 for resetting the triangular block 29 is arranged between the rotating pipe 15 and the fixing block 30. Therefore, when adjusting the rotation speed of the driving motor 2, the rotation speed of the rotating disk 27 will be driven, and thus the triangular block 29 can also be driven to do centrifugal motion and change the position of the triangular block 29 on the rotating disk 27.
[0030] The foam introduction part includes an abutting rod 23. A vertical plate 25 is fixed to the top of the built-in baffle 12, and a first return spring 26 for buffering and resetting the drawer box 21 is arranged between the vertical plate 25 and the drawer box 21. The abutting rod 23 is fixed to the side wall of the drawer box 21. A chamfer 24 is formed at one end of the abutting rod 23 facing the rotating pipe 15. Since the horizontal position of the abutting rod 23 does not change, and the abutting rod 23 is pushed by the first return spring 26 to abut against the rotating disk 27, when the abutting rod 23 encounters the triangular block 29, it will push the abutting rod 23 to drive the drawer box 21 to move towards the connecting ring 20.
[0031] It should be noted that referring to Figure 9 the state, since the triangular block 29 is an isosceles triangular block, the chamfer 24 of the abutting rod 23 abuts against the triangular block 29. As the triangular block 29 does centrifugal motion, the time for the abutting rod 23 to stay on the tops of the plurality of triangular blocks 29 is determined by the rotation speed of the rotating disk 27.
[0032] That is, the faster the rotation speed, the shorter the time for the abutting rod 23 to stay on the tops of the plurality of triangular blocks 29, and the shorter the time for the drawer box 21 to extend into the connecting ring 20 and stay. That is, finally, the rotation speed of the driving motor 2 is adjusted to control the staying time of the drawer box 21 in the connecting ring 20.
[0033] Since the drawer box 21 slides telescopically on the side wall of the connecting ring 20 through the telescopic hole, a linear support rod 22 is fixed to the top of the drawer box 21, and a breathable film is provided at the top of the support rod 22. Therefore, the foam can enter the drawer box 21 from the upper chamber and then enter the material extrusion pipe 7. It should be noted that when the drawer box 21 enters the connecting ring 20, the foam will enter the drawer box 21 and then enter the material extrusion pipe 7. At the same time, it can also block the original passage from the lower chamber through the connecting ring 20 into the material extrusion pipe 7. This state is the operation of filling the foam; when the drawer box 21 is pulled out of the connecting ring 20 and blocks the telescopic hole, the foam will not enter the connecting ring 20, and the concrete passes through the connecting ring 20 and enters the material extrusion pipe 7. This state is the concrete filling state.
[0034] Therefore, by pulling the drawer box 21, the switching between filling the material extrusion pipe 7 with foam and concrete can be realized.
[0035] By regulating the rotation speed of the driving motor 2, the faster the rotation speed, the less the amount of foam filled, and the slower the rotation speed, the more the amount of foam filled. Therefore, the proportion of foam in the foamed concrete is finally regulated by the rotation speed.
[0036] A material extrusion pipe 7 is provided at the top of the main body 11 of the batching box. A inverted frustum-shaped hole 32 is opened in the material extrusion pipe 7, and the material extrusion pipe 7 is used to connect the main body 11 of the batching box and the top of the lifting plate 8. Refer to Figure 10 the state, the foam is located in the concrete. As the material is lifted, the foam will also be lifted together. Due to the existence of the inverted frustum-shaped hole 32, when the foam is lifted to the top of the material extrusion pipe 7, the concrete originally located at the top of the foam will slide down along the periphery as the diameter of the inverted frustum-shaped hole 32 increases, and the concrete will wrap the foam, completing the production of the foamed concrete.
[0037] A lifting plate 8 is provided above the baffle plate 5. The lifting plate 8 slides on the main body 1 of the mixing box through the electric lifting rod 10. A bottom hole 9 coaxially arranged with the material extrusion pipe 7 is provided at the bottom of the lifting plate 8. An electric intercepting plate is provided in the bottom hole 9. When the concrete with foam is pushed up from the bottom to the lifting plate 8, after filling is completed, the electric intercepting plate is opened to block the bottom hole 9 with the electric intercepting plate. The electric intercepting plate is an existing technology and will not be elaborated here. Then the electric lifting rod 10 is opened to lift out the concrete with foam.
[0038] The working principle of the present invention is as follows: First, after starting the drive motor 2, it drives the rotating shaft extending into the mixing tank body 1 to rotate, and then drives the concrete inside the mixing tank body 1 to be stirred. When the drive motor 2 drives the rotating shaft to rotate, it drives the batching tank body 11 and multiple rotating pipes 15 on the side to rotate together. In this way, the rotating pipe 15 slides inside the inner cavity 18, and the meshing gear 19 meshes with the annular tooth plate, so the rotating pipe 15 will be driven to rotate. When the mixing part 6 rotates, the mixing fan blades 63 will rotate, and the concrete will be pushed by the feeding strip holes 64, so that the concrete is continuously squeezed into the guide pipe 14. In this way, the mixing fan blades 63 can not only play the role of mixing concrete, but also squeeze the concrete into the guide pipe 14.
[0039] The rotation of the rotating pipe 15 will drive the rotating disk 27 to rotate together. It should be noted that by adjusting the rotation speed of the drive motor 2, the faster the rotation speed of the rotating shaft, the faster the rotation speed of the rotating pipe 15. Since the triangular block 29 is an isosceles triangular block, the chamfer 24 of the abutting rod 23 abuts against the triangular block 29. As the triangular block 29 makes a centrifugal motion, the time for the abutting rod 23 to stay on the tops of multiple triangular blocks 29 is determined by the rotation speed of the rotating disk 27, that is, the faster the rotation speed, the shorter the time for the abutting rod 23 to stay on the tops of multiple triangular blocks 29, and the shorter the time for the drawing box 21 to extend into and stay in the connecting ring 20. That is, finally, by adjusting the rotation speed of the drive motor 2, the staying time of the drawing box 21 in the connecting ring 20 can be controlled.
[0040] When the drawing box 21 enters the connecting ring 20, the foam will enter the drawing box 21 and then enter the extrusion pipe 7. At the same time, it can also block the foam that originally passed through the lower chamber and entered the extrusion pipe 7 through the connecting ring 20. This state is the operation of filling foam; when the drawing box 21 is pulled out of the connecting ring 20 and blocks the expansion hole, the foam will not enter the connecting ring 20, and the concrete passes through the connecting ring 20 and enters the extrusion pipe 7. This state is the concrete filling state. Therefore, by pulling the drawing box 21, the switching between filling the extrusion pipe 7 with foam and concrete can be realized.
[0041] Due to the existence of the inverted frustum hole 32, the foam rises to the top of the extrusion pipe 7. The concrete originally located on the top of the foam will slide down along the periphery and wrap the foam as the diameter of the inverted frustum hole 32 increases, completing the production of foamed concrete. When the concrete with foam is pushed up from bottom to top into the lifting plate 8, after filling is completed, the electric intercepting plate is opened to block the bottom hole 9, and then the electric lifting rod 10 is opened to lift out the concrete with foam.
[0042] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
