Technical Field
[0001] This utility model relates to the field of asphalt processing equipment technology, and in particular to a homogenizer for cold-mixed and cold-laid emulsified asphalt mixtures. Background Technology
[0002] With the widespread application of cold-mixed and cold-laid emulsified asphalt mixtures in road construction, their advantages such as environmental protection, energy saving, and convenient construction are becoming increasingly prominent. This new type of mixture can be mixed and laid under normal temperature conditions, which not only significantly reduces energy consumption and carbon emissions, but also greatly shortens the construction cycle. It is particularly suitable for rapid maintenance of urban roads and construction in low-temperature seasons.
[0003] However, during the laboratory research and development stage, when this new type of mixture is prepared by mixing and stirring, due to the high viscosity of the material, the amount of the mixture remaining on the inner wall of the mixing tank after mixing can reach 3-5% of the total amount of material. This not only increases the cleaning workload of the operators, but also causes deviations in the experimental data of each batch, which seriously affects the research and development efficiency.
[0004] Therefore, to address the above problems, a homogenizing mixer for cold-mixed and cold-laid emulsified asphalt mixtures can be designed. During the mixing and unloading process, it can automatically clean the material remaining on the inner wall of the mixing drum and discharge it normally, reducing the cleaning intensity for operators and reducing experimental errors. Utility Model Content
[0005] To overcome the problem that during the laboratory research and development stage, when this new type of mixture is prepared by mixing and stirring, due to the high viscosity of the material, the amount of the mixture remaining on the inner wall of the mixing tank after mixing can reach 3-5% of the total amount of material. This not only increases the cleaning workload of the operators, but also causes deviations in the experimental data of each batch, which seriously affects the research and development efficiency.
[0006] The technical solution of this utility model is as follows: a homogenizing mixer for cold-mixed and cold-laid emulsified asphalt mixture, comprising a base, a mixing drum, a top cover, a mixing assembly, a rotating shaft, and a vibrating motor. The mixing drum is fixedly installed inside the base, the top cover is located at the upper end of the mixing drum, the rotating shaft is rotatably connected to the inside of the top cover, and the rotating shaft is located inside the mixing drum. Two sets of mounting brackets are fixedly installed around the rotating shaft. An adjusting frame is slidably connected to one side of the mounting bracket, and an elastic scraper is fixedly installed on one side of the adjusting frame. The elastic scraper contacts the inner wall of the mixing drum. Multiple sets of set screws are threaded inside the mounting bracket, and a connecting plate is fixedly installed at one end of the set screw. The connecting plate is rotatably connected to the adjusting frame. Two sets of vibrating motors are fixedly installed around the mixing drum, and the mixing assembly is located around the rotating shaft.
[0007] Preferably, the rotating shaft allows the mixing assembly to stir and mix various raw materials in the mixing tank. The rotating shaft, via the mounting bracket, drives the elastic scraper to rotate, thus cleaning the inner wall of the mixing tank and preventing highly viscous materials from adhering and remaining, ensuring thorough mixing. When unloading the mixing tank after mixing, the rotating shaft continues to rotate, and a vibration motor drives the mixing tank to vibrate. The material scraped off by the elastic scraper falls with the vibration and is discharged normally. The vibration also prevents material accumulation and blockage during discharge. A set screw rotates within the mounting bracket, and a connecting plate allows the adjusting frame to slide within the bracket, adjusting the pressure of the elastic scraper on the inner wall of the mixing tank. This ensures that, in a laboratory environment, when preparing materials of different viscosities, the elastic scraper can smoothly scrape off any remaining material from the inner wall of the mixing tank, making it more versatile.
[0008] Preferably, the top of the top cover is connected to a feeding port, and the bottom of the mixing tank is connected to a discharge pipe. An electrically controlled valve is installed at the connection between the discharge pipe and the mixing tank.
[0009] Preferably, the upper end of the base is provided with a reserved groove, which is located directly below the discharge pipe.
[0010] Preferably, the upper end of the mixing tank is provided with an annular groove, and a sealing ring is fixedly installed at the lower end of the top cover, with the sealing ring corresponding to the annular groove.
[0011] Preferably, the stirring assembly includes a motor, long stirring blades and short stirring blades. The motor is fixedly installed on the upper end of the top cover, and the output end of the motor is fixedly connected to the rotating shaft. Multiple long stirring blades are fixedly installed on the periphery of the rotating shaft, and multiple short stirring blades are fixedly installed on the periphery of the motor.
[0012] Preferably, both long and short stirring blades are arranged in groups of three, with multiple groups of long and short stirring blades arranged in a uniform, staggered linear pattern.
[0013] Preferably, two sets of telescopic rods are symmetrically fixedly installed on the upper end of the base, and a connecting bracket is fixedly installed on the output end of the telescopic rod, which is fixedly connected to the top cover.
[0014] The beneficial effects of this utility model are: 1. The elastic scraper can clean the inner wall of the mixing tank while the shaft is rotating, preventing highly viscous materials from sticking and remaining on the inner wall of the mixing tank, ensuring thorough mixing. When the mixing tank is unloaded after mixing, the shaft continues to rotate. At the same time, the vibration motor drives the mixing tank to vibrate. The material scraped off by the elastic scraper will fall with the vibration and be discharged normally. The vibration can also prevent the material from accumulating and causing blockage during discharge. 2. The set screw rotates within the mounting bracket, and the connecting plate pushes the adjusting frame to slide within the mounting bracket, thereby adjusting the pressure of the elastic scraper on the inner wall of the mixing tank. This ensures that, in a laboratory environment, when preparing materials of different viscosities, the elastic scraper can smoothly scrape off the material remaining on the inner wall of the mixing tank, making it more versatile.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0017] Please see Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment: a homogenizer for cold-mixed and cold-laid emulsified asphalt mixtures, comprising a base 1, a mixing drum 2, a top cover 201, a mixing assembly, a rotating shaft 3, and a vibrating motor 4. The mixing drum 2 is fixedly installed inside the base 1, the top cover 201 is located at the upper end of the mixing drum 2, the rotating shaft 3 is rotatably connected to the inside of the top cover 201, and the rotating shaft 3 is located inside the mixing drum 2. Two sets of mounting brackets 301 are fixedly installed around the rotating shaft 3. An adjusting frame 302 is slidably connected to one side of the mounting bracket 301, and an elastic scraper 303 is fixedly installed on one side of the adjusting frame 302. The elastic scraper 303 contacts the inner wall of the mixing drum 2. Multiple sets of set screws 304 are threaded inside the mounting bracket 301. A connecting plate 305 is fixedly installed at one end of the set screw 304, and the connecting plate 305 is rotatably connected to the adjusting frame 302. Two sets of vibrating motors 4 are fixedly installed around the mixing drum 2, and the mixing assembly is located around the rotating shaft 3. By rotating the rotating shaft 3, the mixing assembly can be used to control the mixing drum. The various raw materials in the mixing tank 2 are mixed. When the rotating shaft 3 rotates, it drives the elastic scraper 303 to rotate through the mounting bracket 301. The elastic scraper 303 can clean the inner wall of the mixing tank 2, preventing the highly viscous mixture from sticking and remaining on the inner wall of the mixing tank 2, and ensuring thorough mixing. When the mixing tank 2 is unloaded after mixing, the rotating shaft 3 continues to rotate. At the same time, the vibration motor 4 drives the mixing tank 2 to vibrate. The material scraped off by the elastic scraper 303 will fall with the vibration and be discharged normally. The vibration can also prevent the material from accumulating and clogging during discharge. The set screw 304 rotates in the mounting bracket 301. The connecting plate 305 can push the adjusting frame 302 to slide in the mounting bracket 301, thereby adjusting the pressure of the elastic scraper 303 on the inner wall of the mixing tank 2. This ensures that when preparing materials of different viscosities in a laboratory environment, the elastic scraper 303 can smoothly scrape off the material remaining on the inner wall of the mixing tank 2, making it more applicable.
[0018] Please see Figure 1 , Figure 2 and Figure 3In this embodiment, a feeding port 204 is connected to the upper end of the top cover 201, and a discharge pipe 205 is connected to the lower end of the mixing tank 2. An electric control valve 206 is provided at the connection between the discharge pipe 205 and the mixing tank 2. By providing the feeding port 204, materials can be added to the mixing tank 2 when the top cover 201 is closed. By providing the electric control valve 206, the discharge pipe 205 can be controlled. After the materials in the mixing tank 2 are mixed, the discharge pipe 205 is opened to discharge the materials. A reserved groove 101 is provided at the upper end of the base 1, and the reserved groove 101 is located directly below the discharge pipe 205. By providing the reserved groove 101, a larger receiving container can be easily placed under the mixing tank 2, and the receiving container can be aligned with the discharge pipe 205 to hold the discharged mixture. An annular groove 202 is provided at the upper end of the mixing tank 2. A sealing ring 203 is fixedly installed at the lower end of the top cover 201, and the sealing ring 203 corresponds to the annular groove 202. By setting the annular groove 202 and the sealing ring 203 together, the connection between the top cover 201 and the mixing tank 2 can be sealed when the top cover 201 is closed, preventing external impurities from entering and affecting the experimental data. Two sets of telescopic rods 501 are symmetrically fixedly installed at the upper end of the base 1. A connecting bracket 502 is fixedly installed at the output end of the telescopic rod 501, and the connecting bracket 502 is fixedly connected to the top cover 201. By setting the connecting bracket 502, the top cover 201 can be connected and fixed to the output end of the telescopic rod 501. Thus, the top cover 201 can be easily lifted and opened by setting the telescopic rod 501, which is convenient for the operator to clean up after the experiment and reduces the labor intensity of the operator.
[0019] Please see Figure 2 and Figure 3 In this embodiment, the stirring assembly includes a motor 306, long stirring blades 307, and short stirring blades 308. The motor 306 is fixedly installed on the upper end of the top cover 201, and the output end of the motor 306 is fixedly connected to the rotating shaft 3. Multiple long stirring blades 307 are fixedly installed around the rotating shaft 3, and multiple short stirring blades 308 are fixedly installed around the motor 306. The long stirring blades 307 and the short stirring blades 308 are each grouped in sets of three, and the multiple groups of long stirring blades 307 and multiple groups of short stirring blades 308 are evenly staggered. Linear arrangement; by setting motor 306 to drive rotating shaft 3 to rotate, thereby driving mounting bracket 301, long stirring blade 307 and short stirring blade 308 to rotate synchronously. While using long stirring blade 307 and short stirring blade 308 to mix the materials in mixing tank 2, elastic scraper 303 is used to clean the inner wall of mixing tank 2. The multiple sets of long stirring blades 307 and short stirring blades 308 arranged linearly in an alternating manner can effectively reduce the generation of eddy current effect and ensure that the materials in mixing tank 2 are fully mixed.
[0020] During operation, the top cover 201 is lifted using the telescopic rod 501 in conjunction with the connecting frame. Depending on the viscosity of the mixture to be tested, the adjusting frame 302 is adjusted by rotating the top screw 304, thereby adjusting the pressure between the elastic scraper 303 and the inner wall of the mixing tank 2. This allows the elastic scraper 303 to smoothly scrape off the material remaining on the inner wall of the mixing tank 2 as it rotates. Then, the top cover 201 is lowered using the telescopic rod 501, and the top cover 201 and the mixing tank 2 are sealed by the cooperation of the annular groove 202 and the sealing ring 203 to prevent external impurities from entering. Materials are added to the mixing tank 2 through the feeding port 204. Then, the motor 306 drives the rotating shaft 3 to rotate, thereby driving the mounting bracket 301, long stirring blades 307 and short stirring blades 308 to rotate synchronously. The multiple sets of long stirring blades 307 and short stirring blades 308 arranged in an alternating linear pattern can effectively reduce the generation of eddy currents and ensure that the materials in the mixing tank 2 are fully mixed. The mounting bracket 301 drives the elastic scraper 303 to rotate. The elastic scraper 303 can clean the inner wall of the mixing tank 2 to prevent highly viscous mixtures from sticking and remaining on the inner wall of the mixing tank 2, ensuring thorough mixing. After mixing, ensure that the rotating shaft 3 continues to rotate, and at the same time use the vibration motor 4 to drive the mixing tank 2 to vibrate. The material scraped off by the elastic scraper 303 will fall down with the vibration and be discharged normally. The vibration can also prevent the material from accumulating in the discharge pipe 205 and causing blockage when it is discharged. The reserved slot 101 allows for the convenient placement of a larger receiving container below the mixing tank 2, while also facilitating the alignment of the receiving container with the discharge pipe 205 to hold the discharged mixture.
[0021] Through the above steps, the elastic scraper 303 can clean the inner wall of the mixing tank 2 while the rotating shaft 3 is rotating, preventing the highly viscous mixture from sticking and remaining on the inner wall of the mixing tank 2, ensuring thorough mixing. When the mixing tank 2 is unloaded after mixing, the rotating shaft 3 continues to rotate, and the vibration motor 4 drives the mixing tank 2 to vibrate. The material scraped off by the elastic scraper 303 will fall with the vibration and be discharged normally. At the same time, the vibration can also prevent the material from accumulating and clogging during discharge, which can effectively reduce experimental errors and reduce the cleaning pressure on operators. This solves the problem that in the laboratory research and development stage, when this new type of mixture is prepared by mixing and stirring, due to the high viscosity of the material, the amount of mixture remaining on the inner wall of the mixing tank 2 after mixing can reach 3-5% of the total amount of material. This not only increases the cleaning intensity of operators, but also causes deviations in experimental data for each batch, seriously affecting the research and development efficiency.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
