Description

Technical Field

[0001] This utility model relates to the field of concrete preparation technology, and in particular to a homogenizing mixing device for preparing self-healing concrete. Background Technology

[0002] Self-healing concrete typically achieves self-repair of cracks through microorganisms or encapsulated repair agents. When used, capsules or fibers containing repair agents are usually added to concrete and mixed, as shown in the publication CN110255948B, "Concrete Crack-Resistant Self-Healing Agent and Its Preparation Method and Crack-Resistant Self-Healing Concrete".

[0003] Concrete has a certain viscosity, and the carrier containing the repair agent may not be evenly distributed in it during the mixing process, which may affect the self-healing effect. Secondly, the mixing time should not be too long, as the carrier may be damaged during prolonged mixing, and the properties of the concrete may also change during mixing. Therefore, it is necessary to improve the efficiency of mixing or homogenization. Utility Model Content

[0004] This invention provides a homogeneous mixing device for the preparation of self-healing concrete, aiming to solve the problems of poor mixing uniformity and low mixing efficiency of the above-mentioned self-healing concrete mixing devices.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A homogeneous mixing device for preparing self-healing concrete includes a mounting vessel, wherein a rotating base is coaxially mounted on the bottom of the mounting vessel via a bearing, and a drive motor is mounted on the bottom of the mounting vessel, wherein the output end of the drive motor rotates synchronously with the rotating base coaxially.

[0007] The container is coaxially embedded in the installation vessel. The container is detachably snapped into the rotating base, and the container rotates synchronously with the rotating base in a coaxial manner through the snap-fit.

[0008] The top of the installation vessel is equipped with an off-axis ultrasonic homogenizing component, the output end of which extends into the receiving tank.

[0009] Preferably, the installation vessel includes a vessel body, the top of which is detachably fixed with a top cover by a lifting eye bolt, and the top cover has an installation port on one side of the off-axis for installing an ultrasonic homogenizing component. The bottom of the vessel body is provided with at least three columns at equal intervals around the central axis.

[0010] More preferably, a drive motor is provided at the middle position of the bottom of the vessel body, and the output shaft of the drive motor passes through the bottom of the vessel body and forms a linkage with the bottom rotating shaft of the rotating base through a linkage component.

[0011] Furthermore, the rotating base includes a rotating plate that rotates with the bottom of the vessel body via a bearing. The bottom of the rotating plate is coaxially provided with a rotating shaft, and the top of the rotating plate is coaxially provided with a polygonal snap-fit ​​block for docking with the container.

[0012] Furthermore, the container includes a container body, and the bottom of the container body is provided with a polygonal snap-fit ​​groove, and the polygonal snap-fit ​​groove and the polygonal snap-fit ​​block fit together to form a snap-fit.

[0013] Specifically, both the polygonal snap-fit ​​slot and the polygonal snap-fit ​​block have no fewer than three sides.

[0014] More specifically, the top outer edge of the rotating plate of the rotating base is provided with several limiting rods at equal intervals around the axis. The limiting rods are all perpendicular to the rotating plate, and the limiting rods cooperate to form a limiting groove coaxial with the rotating plate. When the polygonal snap-fit ​​groove and the polygonal snap-fit ​​block fit together to form a snap-fit, the barrel is embedded in the limiting groove, and the outer wall of the barrel and the limiting rod form a limiting fit.

[0015] Specifically, the top two sides of the barrel are provided with oppositely arranged lifting rings.

[0016] More specifically, the ultrasonic homogenizing assembly includes an ultrasonic generator installed at the mounting port, the output end of the ultrasonic generator is vertically downward and connected to an ultrasonic transducer, the output end of the ultrasonic transducer is vertically downward and coaxially connected to an amplitude transformer, the amplitude transformer extends off-axis into the barrel and does not directly contact the inner wall of the barrel.

[0017] Preferably, a flexible protective sleeve is fitted onto the outer side of the amplitude rod.

[0018] The beneficial effects of this utility model are:

[0019] This invention involves placing concrete and a carrier containing a repair agent into a container, then placing the container into an installation vessel and engaging it with a rotating base inside the vessel to achieve synchronous rotation. At this point, the top cover is closed, and an ultrasonic homogenizing component is placed inside the container. The drive motor is then turned on to rotate the rotating base, which in turn rotates the container. The ultrasonic homogenizing component, which is arranged off-axis, acts as a stirring rod to stir the material inside the rotating container. Simultaneously, the ultrasonic homogenizing component also has an ultrasonic homogenizing function, enabling integrated and synchronized mixing and homogenization, thereby improving mixing uniformity and efficiency.

[0030] The embodiments will be further described below with reference to the accompanying drawings.

[0031] like Figures 1-5 As shown, in a preferred embodiment 1, a homogeneous mixing device for preparing self-healing concrete includes a mounting vessel 1, a rotating base 2 coaxially provided at the bottom of the mounting vessel 1 via a bearing, and a drive motor 5 provided at the bottom of the mounting vessel 1. The output end of the drive motor 5 rotates synchronously with the rotating base 2 coaxially.

[0032] The mounting vessel 1 is coaxially embedded with a receiving bucket 3, which is detachably snapped to the rotating base 2, and the receiving bucket 3 and the rotating base 2 rotate synchronously in a coaxial manner through the snap-fit.

[0033] The top of the installation vessel 1 is provided with an off-axis ultrasonic homogenizing component 4, the output end of which extends into the receiving tank 3.

[0034] The installation vessel 1 includes a vessel body 11. The top of the vessel body 11 is detachably fixed with a top cover 12 by a lifting eye bolt 13, which facilitates opening and installation. The top cover 12 has an installation port 14 on one side of the off-axis for installing the ultrasonic homogenizing component 4. The bottom of the vessel body 11 is provided with at least three columns 15 at equal intervals around the central axis to ensure the fixed support of the vessel body 11.

[0035] Before starting this utility model, concrete and a carrier containing repair agent are placed together into the container 3, and then the container 3 is placed into the installation vessel 1 and engaged with the rotating base 2 inside the vessel to form synchronous rotation. At this time, the top cover 12 is put on and the ultrasonic homogenizing component 4 is placed into the container 3.

[0036] When it is necessary to combine stirring and homogenization, the drive motor 5 is turned on to drive the rotating base 2 to rotate, and at the same time, the container 3 is rotated. The ultrasonic homogenizing component 4, which is arranged off-axis, acts as a stirring rod to stir the material in the rotating container 3. At the same time, the ultrasonic homogenizing component 4 also has the function of ultrasonic homogenization, which can realize the integration and synchronization of stirring and homogenization, and improve the uniformity and efficiency of mixing.

[0037] When only homogenization is needed, only the ultrasonic homogenizing component 4 is turned on and the drive motor 5 is turned off. When only stirring is needed, only the drive motor 5 is turned on and the ultrasonic homogenizing component 4 is turned off, making it flexible and convenient to use.

[0038] As a preferred embodiment 2, a drive motor 5 is provided at the middle position of the bottom of the vessel body 11. The output shaft of the drive motor 5 passes through the bottom of the vessel body 11 and forms a linkage with the bottom rotating shaft of the rotating base 2 through a linkage component.

[0039] To ensure the rotation of the rotating base 2, a coupling can be used as the linkage component. The output shaft of the drive motor 5 is linked to the rotating shaft of the rotating base 2 through the coupling.

[0040] As a preferred embodiment 3, the rotating base 2 includes a rotating plate 21 that is rotatably engaged with the bottom of the vessel body 11 via a bearing. The bottom of the rotating plate 21 is coaxially provided with a rotating shaft, and the top of the rotating plate 21 is coaxially provided with a polygonal snap-fit ​​block 22 for connecting to the holding bucket 3.

[0041] The container 3 includes a container body 31. The bottom of the container body 31 is provided with a polygonal snap-fit ​​groove 33 coaxially. The polygonal snap-fit ​​groove 33 and the polygonal snap-fit ​​block 22 fit together to form a snap-fit. On the one hand, this ensures that the container body 31 can rotate synchronously with the rotating plate 21. On the other hand, it ensures the synchronicity and stability of the container body 31 during rotation.

[0042] Both the polygonal snap-fit ​​slot 33 and the polygonal snap-fit ​​block 22 have no fewer than three sides to ensure stability.

[0043] In a preferred embodiment 4, the top outer edge of the rotating plate 21 of the rotating base 2 is provided with a plurality of limiting rods 23 at equal intervals around an axis. The limiting rods 23 are all perpendicular to the rotating plate 21, and the limiting rods 23 cooperate to form a limiting groove coaxial with the rotating plate 21. When the polygonal snap-fit ​​groove 33 and the polygonal snap-fit ​​block 22 fit together to form a snap-fit, the barrel 31 is embedded in the limiting groove, and the outer wall of the barrel 31 forms a limiting fit with the limiting rods 23. The limiting groove can limit the outer wall of the barrel 31, ensuring stability during rotation and facilitating docking and installation. During installation, the barrel 31 is lifted and lowered into the limiting groove, and then slid down along the limiting groove until the bottom of the barrel 31 contacts the rotating plate 21. Then, the barrel 31 is rotated until the polygonal snap-fit ​​groove 33 of the barrel 31 fits together with the polygonal snap-fit ​​block 22 of the rotating plate 21 to form a snap-fit.

[0044] The height of the limit rod 23 shall not exceed the height of the barrel body 31.

[0045] As a preferred embodiment 5, the top two sides of the barrel 31 are provided with oppositely arranged lifting rings 32 to facilitate the lifting and movement of the barrel 31.

[0046] In a preferred embodiment 6, the ultrasonic homogenizing component 4 includes an ultrasonic generator 41 installed at the mounting port 14. The output end of the ultrasonic generator 41 is vertically downward and connected to an ultrasonic transducer 42. The output end of the ultrasonic transducer 42 is vertically downward and coaxially connected to an amplitude transformer 43. The amplitude transformer 43 extends off-axis into the barrel 31 without directly contacting the inner wall of the barrel 31. This ensures ultrasonic homogenization, and all structures are existing.

[0047] In a preferred embodiment 7, a flexible protective sleeve 44 is fitted onto the outer side of the amplitude transformer 43. Common amplitude transformers 43 are typically made of rigid materials such as alloys or stainless steel. To prevent damage to the carrier containing the repair agent during homogenization, in addition to controlling the rotational speed and vibration frequency, a flexible protective sleeve 44 is also needed on the outer side of the amplitude transformer 43. This improves the service life of the amplitude transformer 43 and, more importantly, increases the buffer amplitude, preventing damage caused by direct contact between the carrier and the amplitude transformer 43, which could lead to premature release of the repair agent.

[0048] The working principle of this utility model:

[0049] This invention places concrete and a carrier containing a repair agent into a container 3, then places the container 3 into an installation vessel 1 and engages it with a rotating base 2 inside the vessel to rotate synchronously. At this time, the top cover 12 is placed on top and the ultrasonic homogenizing component 4 is placed into the container 3. The drive motor 5 is turned on to drive the rotating base 2 to rotate, which in turn drives the container 3 to rotate. The ultrasonic homogenizing component 4, which is arranged off-axis, acts as a stirring rod to stir the material in the rotating container 3. At the same time, the ultrasonic homogenizing component 4 also has the function of ultrasonic homogenization, which can realize the integration and synchronization of stirring and homogenization, and improve the mixing uniformity and mixing efficiency.
