Abstract
Description
A fly ash cement mixing device Technical Field
[0001] This utility model relates to the technical field of coal ash cement mixing equipment, and in particular to a coal ash cement mixing device. Background Technology
[0002] Fly ash cement is an environmentally friendly cementitious material made by grinding ordinary silicate cement clinker with an appropriate amount of fly ash (a byproduct of coal combustion in thermal power plants). The active SiO2 and Al2O3 in fly ash can undergo a secondary reaction with the cement hydration product Ca(OH)2 to generate CSH gel, which improves later strength and durability.
[0003] Fly ash cement is gaining increasing attention in modern building materials, mainly due to its environmental protection characteristics and excellent mechanical properties. However, to ensure thorough mixing of fly ash and cement, the use of a mixing device is crucial. Traditional mixing devices, despite using motor-driven mixing blades, often fail to achieve the desired mixing effect. Simply relying on motor-driven mixing blades for simple mixing can easily lead to unevenness. This is mainly because the design and movement of the mixing blades cannot effectively break down the boundaries between materials, especially for fly ash and cement with large differences in particle size and density, which affects the uniformity of mixing.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0027] Example 1:
[0028] Referring to Figures 1 to 4, this is the first embodiment of the present invention. This embodiment provides a fly ash cement mixing device, including a first fixed frame 1 and a mixing drum 2. A driving component 3 is provided on one side of the first fixed frame 1, a swing component 4 is provided on one side of the driving component 3, and a stirring component 6 is provided on one side of the mixing drum 2. By providing the driving component 3, the swing component 4 can be easily driven to rotate. By using the swing component 4 and the stirring component 6 together, the fly ash cement can be easily and evenly mixed.
[0029] The swing assembly 4 includes a connecting block 41 located outside the drive member 3. A connecting frame 42 is rotatably attached to the outside of the connecting block 41. A connecting rod 43 is rotatably attached to one side of the connecting frame 42. The other side of the connecting frame 42 is rotatably connected to the inner wall of the first fixed frame 1 via a rotating shaft. A mounting bracket 44 is fixed to the outside of the connecting rod 43.
[0030] The connecting block 41 has a through hole for easy connection with the rotating rod 32, which allows the rotating rod 32 to easily drive it to shake. The design of the connecting block 41 facilitates the transmission of power to the connecting frame 42. After the connecting frame 42 shakes, it can drive the connecting rod 43 to rotate back and forth. By setting the connecting rod 43, it is easy to connect with the mounting bracket 44.
[0031] The mixing assembly 6 includes a second motor 61 fixed to one side of the sealing disk 5. The output end of the second motor 61 passes through the inner wall of the sealing disk 5 and is fixed with a mixing blade 62 for mixing fly ash cement.
[0032] By setting a second motor 61, the stirring blade 62 can be easily driven to rotate. The stirring blade 62 is designed to mix fly ash cement.
[0033] Example 2:
[0034] This is the second embodiment of the present invention, which is based on the previous embodiment.
[0035] Specifically, the driving component 3 includes a first motor 31 fixed to one side of the first fixed frame 1. The output end of the first motor 31 is fixed with a rotating rod 32 for driving the connecting block 41 to shake, and the rotating rod 32 is inclined.
[0036] By setting the first motor 31, the rotating rod 32 can be easily driven to rotate. Since the rotating rod 32 is inclined, it can drive the connecting block 41 to shake.
[0037] Specifically, the inner wall of the mixing drum 2 is connected to a feed pipe 16, and a valve 17 is provided on the outside of the feed pipe 16.
[0038] By setting the feed pipe 16, the fly ash cement can be easily introduced into the mixing drum 2. The valve 17 is designed to facilitate the control of the fly ash cement entering the mixing drum 2, and can also prevent the fly ash cement from leaking out of the mixing drum 2 when it shakes.
[0039] Example 3:
[0040] This is the third embodiment of the present invention, which is based on the first two embodiments.
[0041] Specifically, a first mounting plate 7 is fixed to one side of the mounting bracket 44 by bolts, and three horizontally mounted first mounting rods 8 are fixed to the inner wall of the first mounting plate 7.
[0042] By setting bolts, the first mounting plate 7 can be easily connected to the mounting bracket 44, which allows the mounting bracket 44 to move the first mounting plate 7, and also makes it easy to disassemble the first mounting plate 7 later. By setting the first mounting plate 7, the three first mounting rods 8 can be easily fixed.
[0043] Specifically, a first insert plate 9 is fixed to the outer side of the first mounting rod 8, and the inner wall of the first insert plate 9 is fixedly connected to the outer side of the mixing drum 2.
[0044] By setting the first mounting rod 8, it is convenient to install and fix the two sets of first insert plates 9. By setting the two sets of first insert plates 9, it is convenient to provide a support point for the mixing drum 2.
[0045] Specifically, a second insert plate 10 is fixed to the outside of the mixing drum 2, and three horizontally installed second mounting rods 11 are fixed to the inner wall of the second insert plate 10.
[0046] By setting the second insert plate 10 and the first insert plate 9 together, the stability of the mixing drum 2 can be easily improved. By setting the second insert plate 10, it is easy to connect with the second mounting rod 11.
[0047] Specifically, a second mounting plate 12 is fixed to the outer side of the second mounting rod 11, and a limit bracket 13 is fixed to the inner wall of the second mounting plate 12 by bolts.
[0048] By setting the second mounting rod 11, it is easy to connect with the second mounting plate 12. By setting the bolt, it is easy to connect the second mounting plate 12 and the limit frame 13, and it is also easy to disassemble the second mounting plate 12 later.
[0049] Specifically, a fixing rod 14 is fixed to the inner wall of the limiting frame 13, and a second fixing frame 15 is rotatably mounted on the outer side and one end of the fixing rod 14.
[0050] By setting the limiting frame 13, it is easy to connect with the fixed rod 14, and the design of the second fixed frame 15 facilitates the rotation of the fixed rod 14, thereby improving the stability of the main body.
[0051] In use, firstly, fly ash cement is introduced into the mixing drum 2 through the feed pipe 16, then the valve 17 is closed, and then the first motor 31 is turned on. The rotation of the first motor 31 drives the rotating rod 32 to rotate, which in turn drives the connecting block 41 to shake. The shaking of the connecting block 41 drives the connecting frame 42 to shake, which in turn drives the connecting rod 43 to rotate back and forth. The back and forth rotation of the connecting rod 43 drives the first mounting plate 7 to shake, which in turn drives the three first mounting rods 8 to shake. The shaking of the first mounting rods 8 drives the two sets of first insert plates 9 to shake, which in turn drives the mixing drum 2 to shake. After the mixing drum 2 shakes, the fly ash cement inside the mixing drum 2 can be shaken. Then, the second motor 61 is turned on, which drives multiple sets of stirring blades 62 to rotate. After the multiple sets of stirring blades 62 rotate, the fly ash cement inside the mixing drum 2 can be stirred. When the two are used together, the fly ash cement can be mixed evenly.
[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
