Description

Technical Field

[0001] This utility model relates to the field of emulsified asphalt technology, specifically to an emulsified asphalt colloid mill. Background Technology

[0002] In the production and preparation of emulsified asphalt, the colloid mill is the core equipment for achieving the micro-dispersion of asphalt. Through a specific mechanical structure and working principle, the colloid mill mixes, shears, and grinds molten asphalt with an aqueous solution containing emulsifier, so that the asphalt is uniformly dispersed in the water in the form of tiny particles, forming a stable emulsion system. The performance of this equipment is crucial, and its core role is reflected in its direct impact on the key indicators of emulsified asphalt.

[0003] However, the rotor and stator structure of traditional colloid mills are fixed, and the grinding gap cannot be dynamically adjusted. This makes it difficult to adapt to the grinding requirements of asphalt with different viscosities, such as base asphalt and modified asphalt. This may result in asphalt particles being larger and unevenly dispersed, affecting the stability and workability of emulsified asphalt. In traditional designs, heating systems such as electric heating blocks, heat conduction plates, and feed sealing covers are independent components that need to be installed and fixed separately, which takes up a lot of space.

[0004] Therefore, an emulsified asphalt colloid mill is needed. Utility Model Content

[0005] This invention addresses the technical problems existing in the prior art by providing an emulsified asphalt colloid mill.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: an emulsified asphalt colloid mill, including a drive assembly, the drive assembly including a beveled cross block, and a transmission shaft fixedly connected to the bottom end of the beveled cross block;

[0007] A grinding assembly includes a grinding shell, a sealing cap fixedly connected to the top of the grinding shell, a hollow cylinder inside the grinding shell, and multiple sliders adapted to the inclined cross block slidably connected inside the hollow cylinder. The end of each slider away from the inclined cross block passes through the outer wall of the hollow cylinder and is fixedly connected to a grinding block, which is adapted to the grinding shell.

[0008] The heating and feeding assembly includes a semi-circular cover fixedly installed on the top of the sealing cover. A second electric push rod is fixedly connected to the top of the semi-circular cover. The transmission end of the second electric push rod passes through the top of the semi-circular cover and is fixedly connected to a heat insulation cover that passes through the sealing cover. An electric heating block is fixedly connected inside the heat insulation cover, and a heat conduction plate is fixedly connected to the bottom of the electric heating block.

[0009] Furthermore, the drive assembly also includes a hollow base, inside which a first electric push rod is fixedly connected. A Z-shaped transmission block is fixedly connected to the transmission end of the first electric push rod. A motor is fixedly connected to the end of the Z-shaped transmission block away from the transmission end of the first electric push rod. The transmission end of the motor is fixedly connected to a transmission shaft.

[0010] Furthermore, a T-shaped groove block is fixedly connected to the outer end of the inclined cross block.

[0011] Furthermore, the slider has a beveled groove at one end close to the beveled cross block, and a T-shaped slot adapted to the T-shaped slot block is formed at the inner end of the beveled groove. The T-shaped slot is slidably connected to the T-shaped slot block.

[0014] Furthermore, the hollow cylinder is rotatably connected to the grinding base.

[0015] The beneficial effects of this utility model are:

[0016] (1) This solution can adjust the spacing between multiple grinding blocks by cooperating with each part of the drive component and each part of the grinding component. By adjusting the distance between the grinding block and the inner wall of the grinding shell, the function of dynamic adjustment of the grinding gap can be realized, which can adapt to the grinding needs of asphalt with different viscosities, such as base asphalt and modified asphalt, so as to achieve better uniformity, thereby improving the stability and construction performance of emulsified asphalt.

[0017] (2) This solution integrates heating and feeding into one unit. The integrated design embeds the heating element inside the sealed cover, such as setting an electric heating block and a heat conduction plate on the inner wall of the sealed cover. This reduces external pipes and connectors, making the equipment structure more compact. The integrated structure allows the heating element to directly contact the feed port, and the heat can be quickly conducted to the material inlet area. This avoids the heat loss in the transmission path caused by the long distance in the traditional split design. In addition, the separation of the heating and grinding shells makes later maintenance more convenient and faster. Attached Figure Description

The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0027] Reference Figures 1-4As shown, this is a preferred embodiment of the present invention of an emulsified asphalt colloid mill, which includes a drive assembly 1. The drive assembly 1 includes a beveled cross block 106, and a drive shaft 105 is fixedly connected to the bottom end of the beveled cross block 106.

[0028] Grinding assembly 2 includes a grinding shell 202, a sealing cap 203 fixedly connected to the top of the grinding shell 202, a hollow cylinder 205 inside the grinding shell 202, and multiple sliders 206 adapted to the inclined cross block 106 slidably connected inside the hollow cylinder 205. The end of the slider 206 away from the inclined cross block 106 passes through the outer wall of the hollow cylinder 205 and is fixedly connected to a grinding block 207, which is adapted to the grinding shell 202.

[0029] The heating and feeding assembly 3 includes a semi-circular cover 301 fixedly installed on the top of the sealing cover 203. A second electric push rod 302 is fixedly connected to the top of the semi-circular cover 301. The transmission end of the second electric push rod 302 passes through the top of the semi-circular cover 301 and is fixedly connected to a heat insulation cover 303 that passes through the sealing cover 203. An electric heating block 304 is fixedly connected inside the heat insulation cover 303. A heat conduction plate 305 is fixedly connected to the bottom end of the electric heating block 304.

[0030] This solution uses the beveled structure of the beveled cross block 106 to fit into the beveled groove of the slider 206. When the beveled cross block 106 moves up and down, the T-shaped groove block 107 slides in the T-shaped groove of the slider 206, forcing the slider 206 to slide radially along the hollow cylinder 205, thereby driving the grinding block 207 to approach or move away from the inner wall of the grinding shell 202.

[0031] The drive assembly 1 also includes a hollow base 101, a first electric push rod 102 is fixedly connected inside the hollow base 101, a Z-shaped transmission block 103 is fixedly connected to the transmission end of the first electric push rod 102, a motor 104 is fixedly connected to the end of the Z-shaped transmission block 103 away from the transmission end of the first electric push rod 102, and the transmission end of the motor 104 is fixedly connected to the transmission shaft 105.

[0032] A T-shaped groove block 107 is fixedly connected to the outer end of the inclined cross block 106.

[0033] The slider 206 has a beveled groove at one end close to the beveled cross block 106, and a T-shaped slot is provided at the inner end of the beveled groove to fit the T-shaped slot block 107. The T-shaped slot is slidably connected to the T-shaped slot block 107.

[0034] The bottom end of the grinding shell 202 is fixedly connected to the grinding seat 201, which is fixedly connected to the hollow base 101, and the outer wall of the grinding shell 202 is connected to the discharge pipe 204.

[0035] The top of the sealing cover 203 has a feed port that communicates with the grinding shell 202 and is compatible with the heat insulation cover 303.

[0036] The hollow cylinder 205 is rotatably connected to the grinding base 201.

[0037] Specific implementation process: When producing emulsified asphalt, the material enters the equipment through the feed port at the top of the sealing cover 203. After being heated and preheated by the feeding component 3, it enters the grinding component 2. Under the drive of the drive component 1, the grinding and dispersion are completed. Finally, the finished product is discharged through the discharge pipe 204. Working principle of the drive component 1: Start the motor 104. The motor 104 drives the inclined cross block 106 to rotate through the transmission shaft 105. The T-shaped groove block 107 at the outer end of the inclined cross block 106 rotates accordingly. Meanwhile, the first electric push rod 102 can adjust the height position of the motor 104 and the transmission shaft 105 through the Z-shaped transmission block 103 according to the viscosity requirements of the asphalt, thereby changing the longitudinal position of the inclined cross block 106 in the hollow cylinder 205. The working principle of the grinding component 2 is as follows: when the inclined cross block 106 rotates, the T-shaped groove block 107 slides and engages with the T-shaped groove on the slider 206, driving the slider 206 to slide radially in the hollow cylinder 205. Since the end of the slider 206 away from the inclined cross block 106 is fixedly connected to the grinding block 207, the spacing between multiple grinding blocks 207 can be adjusted, that is, the dynamic adjustment of the grinding gap between the grinding block 207 and the inner wall of the grinding shell 202 is realized. When the drive shaft 105 drives the inclined cross block 106 to rotate, the slider 206, grinding block 207, and hollow cylinder 205 will rotate together under the support of the grinding seat 201, shearing and grinding the asphalt and emulsifier mixture entering the grinding shell 202. The heating and feeding assembly 3 works as follows: The second electric push rod 302 controls the lifting and lowering of the heat insulation cover 303, the electric heating block 304, and the heat-conducting plate 305. When heating of the material is required, the second electric push rod 302 extends, bringing the heat-conducting plate 305 closer to the feed inlet. The heat generated by the electric heating block 304 is quickly conducted to the material inlet area through the heat-conducting plate 305, preheating the incoming asphalt and other raw materials. Because the heating element is embedded inside the sealing cover 203, the heat conduction path is short, reducing heat loss. Furthermore, the heating assembly is separated from the grinding shell 202, making disassembly and maintenance easier in case of malfunction.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
