Description

Technical Field

[0001] The present application relates to the technical field of asphalt detection, and in particular to a high-speed mixer. Background Art

[0002] Asphalt is a dark brown complex mixture of hydrocarbons of different molecular weights and their non-metallic derivatives. It is also an organic gelling material that is anti-corrosive, waterproof and moisture-proof. It can be used in industries such as coatings, plastics, rubber, and road paving. Asphalt can be mainly divided into three types: petroleum asphalt, coal tar asphalt, and natural asphalt. After asphalt is produced and prepared, its performance needs to be tested.

[0003] Since asphalt will stratify when left standing at room temperature, when testing the performance of asphalt, testers take samples from the asphalt at multiple points, and then conduct subsequent performance tests on the obtained asphalt samples. In order to reduce the errors caused by asphalt property testing, testers need to use a high-speed mixer to stir the asphalt sample first.

[0004] The high-speed mixer in the prior art has a rotating disk connected to the bottom of its rotating shaft, and the rotating disk is driven by the rotating shaft to rotate and stir the asphalt. The inventor believes that the mixer in the prior art has a low efficiency in stirring the asphalt sample to be tested. Utility Model Content

[0005] In order to improve the efficiency of uniformly stirring the asphalt sample to be tested, the present application provides a high-speed mixer.

[0006] The high-speed mixer provided in this application adopts the following technical solution:

[0007] A high-speed mixer, comprising:

[0008] A mounting frame, provided with a side wall for mounting a drive motor;

[0009] A driving motor, a housing of which is fixedly connected to the mounting frame;

[0010] A stirring rod is fixedly connected to the output shaft of the driving motor, and the length direction of the stirring rod is parallel to the axial direction of the output shaft of the driving motor. A guide strip is fixedly connected to the side wall of the stirring rod, and the guide strip is provided with a plurality of flexible convex strips at intervals along its length direction.

[0011] A flexible stirring bar, one end of which is fixedly connected to a sliding block, and the other end of which is fixedly connected to a positioning block;

[0012] The positioning block is fixedly connected to the stirring rod, the sliding block is provided with a sliding hole for the stirring rod to pass through, and the inner wall of the sliding hole is fixed with a plurality of protrusions for engaging with the flexible convex strip.

[0013] By adopting the above technical scheme, the output shaft of the driving motor drives the stirring rod to rotate, and the stirring rod drives the flexible stirring bar to move, and the flexible stirring bar stirs the asphalt sample. At the same time, when the inner diameter of the container for placing the asphalt sample is large, the inspector slides the sliding block toward the side close to the positioning block, and at the same time, the flexible convex strip and the convex point are engaged to fix the sliding block and the stirring rod. As the distance between the positioning block and the sliding block is reduced, the distance between the farthest point of the flexible stirring bar and the stirring rod is increased, thereby improving the efficiency of stirring the asphalt sample.

[0014] Optionally, the cross-sectional shape of the guide bar perpendicular to its own length direction is triangular or trapezoidal, and the width of the guide bar gradually decreases on a side away from the stirring rod.

[0015] By adopting the above technical solution, the guide bar is set to a triangle or a trapezoid, and the width of the guide bar on the side close to the stirring rod is larger, which can improve the connection strength between the guide bar and the stirring rod, and also facilitate the sliding block to slide along the guide bar.

[0016] Optionally, the edge of the guide strip away from the stirring rod is provided with a chamfer.

[0017] By adopting the above technical solution, a chamfer is provided at the edge of the guide bar away from the stirring rod, so that the contact area between the guide bar and the sliding block can be reduced, thereby facilitating the inspection personnel to adjust the position of the sliding block relative to the stirring rod.

[0018] Optionally, the high-speed mixer further comprises:

[0019] At least two stirring blades are fixedly connected to the flexible stirring strip; and the stirring blades are arranged at intervals along the length direction of the flexible stirring strip.

[0020] By adopting the above technical solution, when the output shaft of the driving motor drives the flexible stirring bar to rotate, the flexible stirring bar also drives the stirring plate to rotate. Both the flexible stirring bar and the stirring plate can drive the asphalt sample to rotate, so that the asphalt sample to be tested is mixed evenly.

[0021] Optionally, the positioning block is provided with a positioning hole for cooperating with the stirring rod;

[0022] The stirring rod is provided with a fixing hole, the positioning block is provided with a limiting hole, a positioning rod is connected between the stirring rod and the positioning block, and the positioning rod passes through the fixing hole and the limiting hole in sequence.

[0023] By adopting the above technical solution, the positioning rod passes through the fixing hole and the limiting hole, so that the stirring rod and the positioning block are connected as one. After the flexible stirring bar stirs the asphalt sample, the positioning rod is disassembled to separate the positioning block and the sliding block from the stirring rod, thereby improving the efficiency of the inspector in cleaning the residual asphalt on the stirring rod.

[0024] Optionally, one end of the stirring rod away from the output shaft of the driving motor is provided with a chamfer.

[0025] By adopting the above technical solution, the stirring rod is chamfered, which can facilitate the stirring rod to extend into the positioning hole, thereby improving the efficiency of connecting the stirring rod and the positioning block as one.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] By setting a stirring rod connected to the output shaft of the driving motor, the output shaft of the driving motor drives the stirring rod to rotate, and at the same time the stirring rod drives the flexible stirring bar to move, and the flexible stirring bar stirs the asphalt sample. At the same time, when the inner diameter of the container for placing the asphalt sample is large, the inspector slides the sliding block toward the side close to the positioning block, and at the same time the flexible convex strip and the convex point are engaged to fix the sliding block and the stirring rod. As the distance between the positioning block and the sliding block is reduced, the distance between the farthest point of the flexible stirring bar and the stirring rod is increased, thereby improving the efficiency of stirring the asphalt sample.

[0031] The following is combined with Figure 1-2 This application is described in further detail.

[0032] The present application discloses a high-speed mixer, referring to Figure 1 and Figure 2The high-speed mixer provided in the present application comprises a mounting frame 1, a driving motor 2, a stirring rod 3 and a flexible stirring bar 6. The mounting frame 1 is provided with a side wall for installing the driving motor 2, and the mounting frame 1 is made of cast iron; the housing of the driving motor 2 is connected to the mounting frame 1 by bolts, and the output shaft of the driving motor 2 is arranged vertically.

[0033] The stirring rod 3 is cylindrical and is fixedly connected to the output shaft of the driving motor 2 by means of a threaded connection. The length direction of the stirring rod 3 is parallel to the axial direction of the output shaft of the driving motor 2. The side wall of the stirring rod 3 is fixedly connected to the guide bar 4 by means of bonding. The guide bar 4 has a plurality of flexible ridges 5 arranged at intervals along its length direction. Both the flexible ridges 5 and the guide bar 4 can be made of rubber material.

[0034] One end of the flexible stirring bar 6 is fixedly connected to a sliding block 61 by welding, and the other end is fixedly connected to a positioning block 62 by welding. The sliding block 61 and the positioning block 62 are both cylindrical. The outer wall of the sliding block 61 is connected to the flexible stirring bar 6, and the outer wall of the positioning block 62 is also connected to the flexible stirring bar. The flexible stirring bar 6 can be implemented as a metal sheet.

[0035] The positioning block 62 is fixedly connected to the stirring rod 3; the sliding block 61 is provided with a sliding hole 611 for the stirring rod 3 to pass through, the sliding block 61 is slidably connected to the stirring rod 3, and the inner wall of the sliding hole 611 is fixed with a plurality of convex points for engaging with the flexible convex strip 5. When the positioning block 62 and the sliding block 61 are installed on the stirring rod 3, the flexible stirring strip 6 is in an arc shape, and the stirring rod 3 drives the flexible stirring strip 6 to rotate, thereby mixing the asphalt sample to be tested.

[0036] By connecting the stirring rod 3 and the flexible stirring bar 6 at the output shaft of the driving motor 2, the output shaft of the driving motor 2 drives the stirring rod 3 to rotate, and at the same time, the stirring rod 3 drives the flexible stirring bar 6 to move, and the flexible stirring bar 6 stirs the asphalt sample. At the same time, when the inner diameter of the container for placing the asphalt sample is large, the inspector slides the sliding block 61 toward the side close to the positioning block 62, and at the same time, the flexible convex strip 5 is engaged with the convex point to fix the sliding block 61 and the stirring rod 3. As the distance between the positioning block 62 and the sliding block 61 is reduced, the distance between the farthest point of the flexible stirring bar 6 and the stirring rod 3 is increased, thereby improving the efficiency of stirring the asphalt sample.

[0037] In some embodiments, the positioning block 62 can be connected to the stirring rod 3 as a whole by a threaded connection, or can be connected to the stirring rod 3 as a whole by a pin connection. In this embodiment, the positioning block 62 is connected to the stirring rod 3 as a whole by a pin connection.

[0038] Specifically, the positioning block 62 is provided with a positioning hole 621 for cooperating with the stirring rod 3, and the stirring rod 3 is provided with a fixing hole 31, and the length direction of the fixing hole 31 is perpendicular to the axial direction of the stirring rod 3; the positioning block 62 is provided with a limiting hole 622, and the opening direction of the limiting hole 622 is also perpendicular to the length direction of the stirring rod 3, and a positioning rod 8 is also connected between the stirring rod 3 and the positioning block 62, and the radius of the positioning rod 8 is less than or equal to the radius of the limiting hole 622, and the positioning rod 8 passes through the fixing hole 31 and the limiting hole 622 in sequence, so that the stirring rod 3 and the positioning block 62 are connected as a whole.

[0039] By setting the positioning rod 8 to pass through the fixing hole 31 and the limiting hole 622, the stirring rod 3 and the positioning block 62 are connected as a whole. After the flexible stirring bar 6 stirs the asphalt sample, the positioning block 62 and the sliding block 61 are separated from the stirring rod 3 by removing the positioning rod 8, thereby improving the efficiency of the inspector in cleaning the residual asphalt on the stirring rod 3.

[0040] In some embodiments, in order to further improve the efficiency of the connection between the stirring rod 3 and the positioning block 62, a chamfer is provided at one end of the stirring rod 3 away from the output shaft of the driving motor 2. The chamfer can be implemented as an oblique angle or a rounded angle.

[0041] By providing a chamfer on the end of the stirring rod 3, the size of the end of the stirring rod 3 can be reduced, thereby facilitating the stirring rod 3 to extend into the positioning hole 621 through the provided chamfer, thereby improving the efficiency of connecting the stirring rod 3 and the positioning block 62 as one.

[0042] Optionally, the cross-section of the guide bar 4 perpendicular to its length direction is triangular or trapezoidal, and the width of the guide bar 4 gradually decreases on the side away from the stirring rod 3. In the embodiment of the present application, the cross-section of the guide bar 4 is implemented as a trapezoid, and the upper bottom of the cross-section of the guide bar 4 is arranged away from the side of the stirring rod 3.

[0043] By adopting the above technical solution, the guide bar 4 is set to be a triangle or a trapezoid, and the width of the guide bar 4 on the side close to the stirring rod 3 is larger, which can improve the connection strength between the guide bar 4 and the stirring rod 3. At the same time, it can also facilitate the sliding block 61 to slide along the guide bar 4, thereby improving the reliability of the guide bar 4 driving the flexible stirring bar 6 to rotate.

[0044] In some embodiments, the edge of the guide strip 4 away from the stirring rod 3 is provided with a chamfer, and the chamfer can be implemented as a rounded corner or a beveled corner.

[0045] By adopting the above technical solution, a chamfer is provided at the edge of the guide bar 4 away from the stirring rod 3, so that the contact area between the guide bar 4 and the sliding block 61 can be reduced, thereby facilitating the inspection personnel to adjust the position of the sliding block 61 relative to the stirring rod 3.

[0046] In some embodiments, the high-speed blender provided in the present application further includes at least two stirring blades 7 , which are fixedly connected to the flexible stirring bar 6 by welding; and the stirring blades 7 are arranged at intervals along the length direction of the flexible stirring bar 6 .

[0047] Exemplarily, in the embodiment of the present application, three stirring blades 7 are provided, and the three stirring blades 7 are all arranged horizontally, and the three stirring blades 7 are arranged at intervals along the length direction of the flexible stirring bar 6 .

[0048] When the output shaft of the driving motor 2 drives the flexible stirring bar 6 to rotate, the flexible stirring bar 6 also drives the stirring blade 7 to rotate. Both the flexible stirring bar 6 and the stirring blade 7 can drive the asphalt sample to rotate, so that the asphalt sample to be tested is mixed evenly.

[0049] The implementation principle of a high-speed mixer provided in the present application is: by connecting the stirring rod 3 and the flexible stirring bar 6 at the output shaft of the driving motor 2, the output shaft of the driving motor 2 drives the stirring rod 3 to rotate, and at the same time, the stirring rod 3 drives the flexible stirring bar 6 to move, and the flexible stirring bar 6 stirs the asphalt sample. At the same time, when the inner diameter of the container for placing the asphalt sample is large, the inspection personnel slides the sliding block 61 toward the side close to the positioning block 62, and at the same time, the flexible convex strip 5 is engaged with the convex point to fix the sliding block 61 and the stirring rod 3. Since the distance between the positioning block 62 and the sliding block 61 is reduced, the distance between the farthest point of the flexible stirring bar 6 and the stirring rod 3 is increased, thereby improving the efficiency of stirring the asphalt sample.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
