Abstract
Description
Technical Field
[0001] This utility model relates to the field of dispersion device technology, specifically to a device for uniformly dispersing modified asphalt additives. Background Technology
[0002] A modified asphalt additive dispersion unit is a key piece of equipment used to uniformly disperse modifiers (such as SBS, rubber powder, polymers, etc.) into asphalt. Traditional dispersion units typically employ a stirring or screw conveyor structure, achieving initial fusion of the additives and asphalt through mechanical shearing and mixing. Common modified asphalt additive dispersion units consist of a mixing tank, a stirring assembly, and a dispersion assembly. The following drawbacks have been observed during their use:
[0003] 1. Uneven dispersion and low efficiency: Traditional devices usually use unidirectional stirring or conveying methods, and the additives only move in one direction in the dispersion cylinder, resulting in insufficient dispersion in some areas, and the phenomenon of agglomeration or uneven distribution.
[0004] 2. Inability to adjust discharge port size: Existing equipment typically has a fixed discharge port design, making it impossible to flexibly adjust the opening size according to the type of additive or process requirements. This results in the inability to accurately control the amount of additive discharged during dispersion, potentially causing over- or under-discharge, which in turn affects the final performance of the modified asphalt.
[0005] Therefore, in view of this, we studied and improved the existing structure and proposed a device for uniformly dispersing modified asphalt additives. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-3A device for uniformly dispersing modified asphalt additives includes a mixing tank 1, a mixing component 2 inside the mixing tank 1, and a dispersing component 3 below the mixing tank 1. The mixing tank 1 includes a tank body 101 and a cover 102. Several latches 103 are provided on the tank body 101 and are fastened to the cover 102, enabling the tank body 101 and the cover 102 to be disassembled and assembled. An inlet 104 is fixedly provided through the cover 102, and an outlet 105 is fixedly provided through the bottom of the tank body 101. A screw-on rotating cap is provided on the inlet 104, and a switch valve 106 is provided on the outlet 105. The mixing component 2 is provided on the cover 102. The mixing component 2 includes a mixing rod 201 rotatably provided at the bottom of the cover 102, and several mixing blades 202 are evenly distributed and fixedly provided around the mixing rod 201. A motor 203 for driving the mixing rod 201 to rotate is fixedly provided on the top of the cover 102. The rotation of the stirring rod 201 can drive the rotation of several stirring blades 202, thereby stirring the contents of the barrel 101.
[0028] Please see Figure 1 , Figure 4 The dispersing component 3 includes a dispersing cylinder 301 fixedly connected to the discharge port 105. A support rod 107 is fixedly installed between the barrel body 101 and the dispersing cylinder 301. A frame plate 302 is fixedly installed on both sides of the dispersing cylinder 301. Several discharge ports 303 are evenly distributed at the bottom of the dispersing cylinder 301. An adjusting component 4 for adjusting the size of the discharge ports 303 is installed on the outside of the dispersing cylinder 301. The adjusting component 4 includes several arc-shaped baffles 401, which are divided into two groups. Each group of arc-shaped baffles 401 is connected by two connecting rods 402. The two connecting rods 402 are slidably connected to the dispersing cylinder 301. A support rod 107 is fixedly installed on one side of the dispersing cylinder 301. Two receiving plates 403 are provided, and a bidirectional threaded rod 404 is rotatably connected between the two receiving plates 403. The bidirectional threaded rod 404 is threadedly rotatably connected to two connecting rods 402. The bidirectional threaded rod 404 is provided with positive thread and negative thread, and the positive thread and negative thread are opposite. One connecting rod 402 is provided with a positive thread hole for the positive thread to rotate; the other connecting rod 402 is provided with a negative thread hole for the negative thread to rotate. A motor 405 for driving the bidirectional threaded rod 404 to rotate is fixedly provided on one side of one of the receiving plates 403. The arc-shaped baffle 401 moves to block the discharge port 303, thereby adjusting the discharge size of the discharge port 303. Since the positive thread is rotatably connected to the positive thread hole thread and the negative thread is rotatably connected to the negative thread hole thread, when the bidirectional thread rod 404 rotates, it can drive the two connecting rods 402 to move in opposite directions. When the arc-shaped stop bar 401 blocks the discharge port 303, the discharge size of the discharge port 303 can be controlled.
[0029] Please see Figure 1 , Figure 4A receiving plate 304 is fixedly installed in the middle of the dispersion cylinder 301. Two spiral conveying assemblies 5 are installed inside the dispersion cylinder 301, with each assembly positioned on either side of the receiving plate 304. Each spiral conveying assembly 5 includes a conveying rod 501 rotatably mounted between the receiving plate 304 and the inner side of the dispersion cylinder 301. Spiral blades 502 are fixedly wound around the conveying rod 501. A motor 503 is fixedly installed on one side of the dispersion cylinder 301 to drive the conveying rod 501 to rotate. The rotation of the conveying rod 501 drives the spiral blades 502 to rotate, allowing the additive to be conveyed within the dispersion cylinder 301. Since there are two spiral conveying assemblies 5 with different rotation directions, the additive can be conveyed to both ends of the dispersion cylinder 301.
[0030] The working principle of this utility model:
[0031] When it is necessary to disperse the modified asphalt additive, the modified asphalt additive can be added into the barrel 101 through the inlet 104. Then, the motor 203 can be started, which will drive the stirring rod 201 to rotate, causing several stirring blades 202 to rotate, thereby stirring the modified asphalt additive. Then, the switch valve 106 can be rotated to open, and the motor 503 can be started, which will drive the transmission rod 501 to rotate, causing the spiral blade 502 to rotate, thereby transmitting the modified asphalt additive, so that the additive is dispersed through the outlet 105.
[0032] If it is necessary to adjust the size of the discharge port 105, the motor 405 can be started, which will drive the bidirectional threaded rod 404 to rotate, causing the two connecting rods 402 to move in opposite directions, thereby causing the arc-shaped baffle 401 to move as well, thus blocking the discharge port 105. The size of the discharge port 105 can be adjusted by the area of the discharge port 105 being blocked.
[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
