Description

Technical Field

[0001] This utility model relates to the field of concrete technology, and in particular to a densified silica fume pre-dispersion device. Background Technology

[0002] In the field of concrete additives, dense silica fume is widely used due to its high pozzolanic activity. However, its extremely fine particle size (average particle size 0.1-0.3μm) and low bulk density lead to high collection, transportation, and storage costs, and it is also prone to agglomeration into hard lumps when exposed to moisture. Therefore, silica fume is usually densified before storage and transportation (the dust collection process involves physical compression and densification). To ensure the effectiveness of silica fume in downstream applications such as concrete and refractory materials, it undergoes pre-dispersion treatment.

[0003] Currently, in traditional pre-dispersion processes, manual crushing for dispersion is inefficient and causes serious dust pollution. Meanwhile, many mechanical mixing devices use fixed vertical cylinders, which are bulky and make it inconvenient to discharge materials quickly. In addition, the mixing mechanism is mostly a single-layer blade, which has limited crushing effect and needs further optimization.

[0004] Therefore, this application provides a device for pre-dispersing encrypted silica fume to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a pre-dispersion device for densified silica fume to solve the problems of poor unloading during pre-dispersion treatment of densified silica fume in existing processes, resulting in low processing efficiency and insufficient crushing of silica fume.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A pre-dispersed silica fume device includes a base, with vertical supports symmetrically fixed at both ends of the base, and a stirring cylinder rotatably mounted between the top ends of the supports. The top of the stirring cylinder is open and fitted with a sealing cap, and a servo motor is fixed at the bottom of the stirring cylinder. The servo motor is connected to a stirring mechanism located at the bottom of the stirring cylinder. A vertically movable handle is elastically installed on one side of the mixing drum. A vertical positioning rod is fixed to the bottom of the handle, and a positioning seat is fixed to the upper end of the base for the lower end of the positioning rod to be vertically inserted.

[0007] Optionally, an observation window is provided in the middle of the upper end face of the sealing cover.

[0008] Optionally, the stirring mechanism includes a rotating shaft, a first vane, and a second vane. The lower end of the rotating shaft is fixedly connected to the shaft of the servo motor. Multiple first vanes are provided and symmetrically installed in the middle of the rotating shaft. Multiple second vanes are provided and installed on the rotating shaft, and are symmetrically distributed about the first vanes.

[0009] Optionally, the first vane is a horizontal agitator, and the second vane is an agitator bent in a direction away from the first vane.

[0010] Optionally, two fixing ears are fixed on one side of the inner wall of the mixing cylinder, and a vertical slide rod is fixed between the two fixing ears. A movable seat is fixed on one side of the handle, and the movable seat is sleeved on the slide rod and vertically slides and abuts against the inner wall of the mixing cylinder.

[0011] Optionally, a spring is fitted onto the slide rod, the spring being fixed at the top end of the slide rod and elastically abutting the movable seat downwards.

[0012] Optionally, the sealing cap is provided with a locking structure at the upper port edge of the stirring cylinder.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects: In the above solution, thanks to the cooperation of the base, bracket, mixing drum, handle, positioning rod and positioning seat, the silica fume can be placed in the mixing drum for stirring and dispersion pretreatment. It is also convenient to separate the positioning rod from the positioning seat by pulling the handle and tilting the mixing drum to quickly pour out the dispersed silica fume, which helps to improve the pre-dispersion efficiency of silica fume.

[0014] In the above scheme, thanks to the structural design of the stirring mechanism, the combination of the rotating shaft and the first vane, compared with the ordinary stirring structure in the prior art, this stirring mechanism in the upper, middle and lower directions has a better dispersion effect on the dense silica fume in the stirring drum.

[0015] In summary, this device is simple to operate and easy to use, which helps to improve the pre-dispersion efficiency of silica fume. Moreover, the multi-directional stirring process improves the pre-dispersion effect of silica fume, which helps to ensure the subsequent use effect of silica fume. Attached Figure Description

[0025] like Figure 1-4 As shown, an embodiment of this utility model provides a pre-dispersed device for encrypted silica fume, which mainly consists of a base 1, a support 2, a stirring cylinder 3, a sealing cover 4, a servo motor 5, a stirring mechanism 6, a handle 7, a positioning rod 8, and a positioning seat 9.

[0026] The base 1 has vertical supports 2 symmetrically fixed at both ends, and a stirring drum 3 is rotatably mounted between the top ends of the supports 2. The stirring drum 3 is made of high-strength alloy steel, which has good wear resistance and corrosion resistance. Its inner wall is finely polished to reduce the residue of silica ash during the stirring process. The top of the stirring drum 3 is open and fitted with a sealing cap 4. The sealing cap 4 and the upper edge of the stirring drum 3 are equipped with a locking structure to ensure that the sealing cap 4 will not loosen during the stirring process and to prevent silica ash leakage.

[0027] A servo motor 5 is fixed to the bottom of the mixing drum 3. The servo motor 5 can be a high-performance AC servo motor. The servo motor 5 is connected to a stirring mechanism 6 located at the bottom of the mixing drum 3. The stirring mechanism 6 includes a rotating shaft 601, a first vane 602, and a second vane 603. The rotating shaft 601 is made of high-strength stainless steel, and its lower end is fixedly connected to the shaft of the servo motor 5 via a coupling. Two first vanes 602 are provided and symmetrically installed in the middle of the rotating shaft 601. They are arc-shaped flat plates made of stainless steel, possessing a certain strength and rigidity. Eight second vanes 603 are provided and installed on the rotating shaft 601, symmetrically distributed about the first vanes 602. The first vanes 602 are horizontal stirring elements, and the second vanes 603 are stirring elements bent at 30° away from the first vanes 602. The bent portion can use a rounded transition to reduce resistance to silica fume. This unique stirring mechanism 6 design allows the silica fume inside the stirring drum 3 to be stirred in three directions: top, middle, and bottom. Compared to ordinary stirring structures in existing technologies, this results in better dispersion of the silica fume. During the stirring process, the first vane 602 horizontally stirs the silica fume in the middle of the stirring drum 3, while the second vane 603 flips the silica fume at the bottom upwards and presses the silica fume at the top downwards, ensuring thorough mixing and achieving better dispersion.

[0028] A vertically movable handle 7 is elastically installed on one side of the mixing drum 3. Two fixing ears 301, made of stainless steel, are fixed to the inner wall of one side of the mixing drum 3 by welding. A vertical sliding rod 302, made of solid stainless steel and chrome-plated, is fixed between the two fixing ears 301 to improve wear resistance. A movable seat 701, made of engineering plastic and inlaid with bearings, is fixed to one side of the handle 7. The movable seat 701 is fitted onto the sliding rod 302 and slides vertically against the inner wall of the mixing drum 3. A spring 303 is fitted onto the top of the sliding rod 302 and elastically presses the movable seat 701 downwards. A vertical positioning rod 8 is fixed to the bottom of the handle 7. The positioning rod 8 is made of stainless steel. A positioning seat 9 is fixed to the upper surface of the base 1 for the lower end of the positioning rod 8 to be vertically inserted. The positioning seat 9 has a positioning hole inside, and the size of the positioning hole is adapted to the outer diameter of the positioning rod 8.

[0029] An observation window 401 is provided in the middle of the upper end face of the sealing cover 4. The observation window 401 is made of high-strength transparent glass, which makes it convenient to observe the liquid level and dispersion of silica fume in the stirring drum 3.

[0030] The working principle of this utility model is as follows: When pre-dispersing silica fume is required, the silica fume is placed in the mixing drum 3, the sealing cover 4 is closed, and the locking structure is tightened. The servo motor 5 is started, driving the stirring mechanism 6 to rotate and disperse the silica fume in the mixing drum 3. During the stirring process, the dispersion of the silica fume can be observed through the observation window 401. After the silica fume dispersion pre-treatment is completed, the sealing cover 4 is removed, and the handle 7 is pulled upwards. The movable seat 701 slides upwards on the slide rod 302, compressing the spring 303 and separating the positioning rod 8 from the positioning seat 9. At this time, the mixing drum 3 can be tilted to quickly pour out the pre-dispersed silica fume. This design makes the device simple to operate, convenient to use, and beneficial to improving the pre-dispersion efficiency of silica fume.

[0031] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
