Description

Technical Field

[0001] The invention complies with the technical field of mixing devices, and in particular relates to a uniform mixing device for a concrete water reducing agent. Background Art

[0002] Water reducer is a reagent that can reduce the amount of water used in the process of mixing and preparing concrete. It needs to enter the concrete material synchronously with water during the process of adding water to the concrete material to play its role in reducing water consumption. However, in the actual process of preparing concrete, the amount of water reducer required this time is added to the mixing device at one location, which will cause uneven distribution of the water reducer. Although the water reducer can be evenly distributed through stirring later, the stirring time will inevitably increase. At the same time, during this stirring process, concrete materials that are not immediately in contact with the water reducer will still be stirred with normal water consumption until they come into contact with the water reducer, and their water consumption may be reduced, but at this time their water consumption may have exceeded their normal water consumption after the addition of the water reducer.

DETAILED DESCRIPTION

[0027] The present invention will now be described more fully below with reference to the accompanying drawings, in which currently preferred embodiments of the present invention are shown. However, the present invention may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0028] In the process of preparing concrete, when the amount of water reducer required for this time is added to the mixing device at one location, it will cause uneven distribution of the water reducer, which not only affects the subsequent mixing time, but also the concrete materials that are not immediately in contact with the water reducer will still be mixed with normal water consumption until they come into contact with the water reducer, and their water consumption may be reduced, but at this time their water consumption may be greater than their normal water consumption after adding the water reducer.

The outer shell 11 is provided with a feeding shell 19, which is connected and communicated with the mixing shell 18 by limited rotation. The mixing shell 18 is fixedly connected and communicated with a water inlet pipe 110, which is communicated with a water supply device. The fixed bracket 1 is provided with a second motor 111, and a grinding rod 112 is fixedly connected to the output shaft of the second motor 111. The rotating frame 16 is fixedly connected to the grinding rod 112, and the distances between various locations on the outer wall of the lower part of the grinding rod 112 and various locations on the inner wall of the upper part of the feeding shell 19 are consistent. The grinding rod 112 cooperates with the feeding shell 19 to grind the agglomerated water reducer powder back into a powder state.

[0030] Please refer to Figure 3-Figure 5 As shown, the second rotating shaft 21 is limitedly rotatably connected to the center of the feed shell 19, the second rotating shaft 21 is fixedly connected with stirring rods 22 that are evenly distributed and located in the feed shell 19, the second rotating shaft 21 is fixedly connected with a spiral feeding member 23, the spiral feeding member 23 is located in the feed shell 19, and the spiral feeding member 23 is located above the stirring rod 22, the spiral feeding member 23 is rotatably connected to the feed shell 19, and the spiral feeding member 23 is used to transport the water reducing agent powder into the mixing shell 18, the fixed bracket 1 is installed with a third motor 24, the output shaft of the third motor 24 is provided with a spline rod 25, the spline rod 25 is rotatably connected to the first rotating shaft 14, and the spline rod 25 is spline-connected to the second rotating shaft 21.

[0031] When it is necessary to add water reducer to the concrete, the staff first connects the water inlet pipe 110 to the water supply device, then places the concrete material between the outer shell 11 and the guide block 17, and places the water reducer powder between the feed shell 19 and the grinding rod 112. During this process, the concrete material enters the outer shell 11 and the guide block 17 along the gap between them, and the water reducer powder enters the mixing shell 18 along the gap between the feed shell 19 and the grinding rod 112.

[0032] In the above process, the staff starts the water supply device, the first motor 12 and the second motor 111. The water supply device works to transport water to the mixing shell 18 through the water inlet pipe 110, and the water entering the mixing shell 18 is mixed with the water reducer powder. In this process, the second motor 111 works to drive the grinding rod 112 to rotate through its output shaft, and the grinding rod 112 drives the rotating frame 16 to rotate. The rotating frame 16 drives the mixing shell 18 to rotate through the guide block 17. The mixing shell 18 rotates to throw out the solution (hereinafter referred to as the water reducer solution) after the water in it is mixed with the water reducer powder through the evenly distributed through holes on its outer wall, so that the water reducer solution is evenly mixed with the concrete material in the outer shell 11, so as to prevent the uneven distribution of the water reducer when adding the water reducer to the concrete material. Increased mixing time of the water reducer and the concrete material is prevented.

[0033] During the operation of the second motor 111, the staff starts the third motor 24. The output shaft of the third motor 24 drives the second rotating shaft 21 to rotate through the spline rod 25. The second rotating shaft 21 drives the spiral feeding member 23 and the evenly distributed stirring rods 22 to rotate. The spiral feeding member 23 rotates to transport a certain amount of water reducing agent powder downward, and the evenly distributed stirring rods 22 rotate to stir the water reducing agent and water in the feed shell 19 to mix the two evenly.

[0034] During the operation of the second motor 111, the output shaft of the first motor 12 drives the first rotating shaft 14 to rotate the protective shell 13 through the gear set, and the protective shell 13 drives a plurality of groups of circumferentially distributed stirring blades 15 thereon to rotate, so as to stir the concrete material and the water reducing agent solution in the outer shell 11, so that the concrete material and the water reducing agent solution are fully and evenly mixed, thereby accelerating the mixing speed of the concrete material and the water reducing agent solution.

[0035] During the rotation of the grinding rod 112, the grinding rod 112 cooperates with the feed shell 19 to grind the water-reducing agent powder passing through the gap between them, thereby preventing the water-reducing agent powder that enters the mixing shell 18 from partially agglomerating, resulting in the water-reducing agent powder not being evenly mixed with water, thereby affecting the water-reducing agent solution after contacting the concrete material, and failing to function normally, while preventing the agglomerated water-reducing agent powder from clogging the through holes on the outer wall of the mixing shell 18.

[0036] In the process of mixing the water-reducing agent solution with the concrete material, the staff continuously adds concrete material to the space between the outer shell 11 and the guide block 17, and continuously adds water-reducing agent powder to the space between the feed shell 19 and the grinding rod 112, until the sum of the amount of concrete material on the upper side of the outer shell 11 and the guide block 17 and the amount of concrete material in the outer shell 11 reaches the maximum amount that the device can mix at a single time, the staff stops adding concrete material to the space between the outer shell 11 and the guide block 17, and stops adding water-reducing agent powder to the space between the feed shell 19 and the grinding rod 112. After the concrete material and the water-reducing agent powder in the outer shell 11 are evenly mixed, the mixed material in the outer shell 11 is pumped away by the pumping device.

[0037] In this embodiment, the outer shell 11 is fixedly connected to the fixed bracket 1, the first rotating shaft 14 is fixedly connected to the protective shell 13, the protective shell 13 is fixedly connected to the stirring blade 15, the outer shell 11 is fixedly connected to the feed shell 19, and the output shaft of the third motor 24 is fixedly connected to the spline rod 25, but it is limited to this embodiment. In other embodiments, the outer shell 11 is slidably connected to the fixed bracket 1, the first rotating shaft 14 is splined to the protective shell 13, the protective shell 13 and the stirring blade 15 not connected to the rotating ring 61 are rotatably connected, the outer shell 11 is slidably connected to the feed shell 19, and the output shaft of the third motor 24 is connected to the spline rod 25 via a continuously variable speed device 42. For details, please see the specific description in the subsequent embodiments.

[0038] Example 2: Based on Example 1, please refer to Figure 5-Figure 7 As shown, it also includes a sliding ring 31, which is slidably connected to the rotating frame 16, and two springs are connected between the sliding ring 31 and the rotating frame 16. The sliding ring 31 is rotatably connected to the rotating ring 32, and a connecting rod 33 is fixedly connected to the right part of the lower side of the rotating ring 32. The connecting rod 33 is fixedly connected to a ball head seal 34 that seals with the water inlet pipe 110, and the diameter of the ball head part of the ball head seal 34 is consistent with the inner diameter of the water inlet pipe 110.

[0039] Please refer to Figure 5-Figure 7 As shown, a first hydraulic telescopic member 35 is fixedly connected to the upper portion of the rotating frame 16, and the telescopic end of the first hydraulic telescopic member 35 is fixedly connected to the rotating ring 32. A second hydraulic telescopic member 36 is fixedly connected to the left side of the fixed bracket 1, and the telescopic end of the second hydraulic telescopic member 36 is fixedly connected to the outer shell 11. The outer shell 11 is slidably connected to the fixed bracket 1, and four circumferentially distributed springs are connected between the outer shell 11 and the fixed bracket 1. The feed shell 19 is slidably connected to the outer shell 11. A connecting pipe 37 is connected between the second hydraulic telescopic member 36 and the fixed part of the first hydraulic telescopic member 35. The fixed part of the second hydraulic telescopic member 36, the fixed part of the first hydraulic telescopic member 35 and the connecting pipe 37 are all filled with hydraulic oil.

[0040] A connecting frame 41 is fixedly connected to the lower side of the housing 11 and is connected to the spline rod 25 for limited rotation. The output shaft of the third motor 24 and the spline rod 25 are transmitted through a continuously variable transmission device 42. After the connecting frame 41 drives the spline rod 25 to move downward, the continuously variable transmission device 42 works to change speed, so that the rotation speed of the spline rod 25 is greater than the rotation speed of the output shaft of the third motor 24.

[0041] In the process of adding concrete material between the shell 11 and the guide block 17, as the amount of concrete material on the shell 11 increases, the shell 11 moves downward and compresses the adjacent spring. After the shell 11 moves downward, the gap between the shell 11 and the guide block 17 increases, thereby accelerating the speed at which the concrete material enters the shell 11.

[0042] During the downward movement of the outer shell 11, the outer shell 11 drives the telescopic end of the second hydraulic telescopic component 36 to move downward, and the telescopic end of the second hydraulic telescopic component 36 squeezes the hydraulic oil therein into the fixed part of the first hydraulic telescopic component 35 through the connecting pipe 37. The increase in the hydraulic oil in the first hydraulic telescopic component 35 causes its telescopic end to drive the rotating ring 32 to move upward, and the rotating ring 32 drives the sliding ring 31 and the connecting rod 33 to move upward. The sliding ring 31 moves upward to compress the adjacent spring, and the connecting rod 33 drives the ball head seal 34 to move upward through the connecting rod 33, thereby increasing the flow area in the water inlet pipe 110, thereby accelerating the amount of water entering the feed shell 19 per unit time.

[0043] When the shell 11 moves downward, the shell 11 drives the connecting frame 41 to move downward. The connecting frame 41 moves downward to drive the continuously variable transmission device 42 to work, so that the rotation speed of the spline rod 25 is accelerated, thereby accelerating the rotation speed of the spiral feeding member 23, thereby accelerating the amount of water reducing agent powder transported downward per unit time.

[0044] After the pumping device has pumped away the mixed materials in the housing 11, the housing 11 is reset upwards under the action of the spring between the housing 11 and the fixed bracket 1, and drives other parts to reset.

[0045] Example 3: Based on Example 2, please refer to Figure 8 and Fig. 9 As shown, it also includes several groups of circumferentially distributed rack racks 51 distributed in upper and lower axial arrays, and the several groups of circumferentially distributed rack racks 51 distributed in upper and lower axial arrays are all arranged on the first rotating shaft 14. The first rotating shaft 14 is composed of a round rod, two straight plates and several circular rings. The first rotating shaft 14 is spline-connected to the protective shell 13, and the stirring blade 15 is fixedly connected with a gear 52 meshing with the adjacent rack rack 51.

[0046] Please refer to Figure 8 and Fig. 9As shown, the protective shell 13 is rotatably connected to a rotating ring 61 in an axial array, and the rotating ring 61 in the axial array is rotatably connected to adjacent stirring blades 15 respectively. The stirring blades 15 arranged on the rotating ring 61 and the stirring blades 15 not arranged on the rotating ring 61 are alternately distributed, and an arc spring 62 is connected between the rotating ring 61 and the protective shell 13. The rack racks 51 at the same height as the adjacent rotating rings 61 are all rotatably connected to the first rotating shaft 14, and the remaining rack racks 51 are all fixedly connected to the first rotating shaft 14. The rack racks 51 at the same height as the adjacent rotating rings 61 are all fixedly connected with circular rings, and the circular rings are rotatably connected to the adjacent stirring blades 15, and the protective shell 13 is rotatably connected to the stirring blades 15 not connected to the rotating ring 61.

[0047] During the downward movement of the outer shell 11, the outer shell 11 drives the protective shell 13 to move downward, and the protective shell 13 drives the stirring blades 15 arranged axially and circumferentially thereon to move downward, and the stirring blades 15 drive the adjacent gears 52 to move downward. During the downward movement of the gears 52, the gears 52 mesh with the adjacent racks 51, so the gears 52 drive the adjacent stirring blades 15 to rotate until the outer shell 11 stops moving downward and the stirring blades 15 stop rotating. In this way, when the amount of concrete material in the outer shell 11 increases, the angle of the stirring blades 15 is changed to tilt the stirring blades 15, thereby reducing the contact area between the stirring blades 15 and the concrete material and reducing the resistance encountered by the stirring blades 15 when rotating, thereby protecting the stirring blades 15.

[0048] When the concrete material initially contacts the water-reducing agent solution, the concrete material that contacts the water-reducing agent solution first will agglomerate and prevent other concrete materials from contacting the water-reducing agent solution. At this time, the concrete material and the water-reducing agent solution in the outer shell 11 are stirred by the staggered stirring blades 15, thereby increasing the mixing speed of the concrete material and the water-reducing agent solution in the outer shell 11. This is because the stirring blades 15 on the rotating ring 61 and the other stirring blades 15 form a larger gap in the vertical plane and the top cross section, which is more conducive to the uniform distribution of the concrete material and the water-reducing agent solution in the outer shell 11. At this time, the outer shell 11 does not move downward.

[0049] As more and more concrete is mixed in the shell 11, when the mixed concrete in the shell 11 covers the adjacent swivel 61, the shell 11 moves downward. At this time, the resistance encountered by the stirring blade 15 on the swivel 61 increases, and the stirring blade 15 drives the adjacent swivel 61 to rotate and compresses the adjacent arc spring 62 until the stirring blade 15 on the swivel 61 and the stirring blade not on the swivel 61 are in the same vertical plane, and the swivel 61 stops rotating. At this time, the gap formed by the stirring blade 15 on the swivel 61 and the other stirring blades 15 in the vertical plane and the top cross section is the smallest, so that the stirring blade 15 on the swivel 61 and the other stirring blades 15 can fully stir the mixed concrete in the shell 11.

[0050] After the pumping device extracts the mixed materials in the housing 11 , the rotating ring 61 drives the adjacent parts to reset under the action of the arc spring 62 .

[0051] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
