Abstract
Description
Technical Field
[0001] This utility model relates to the field of ingredient technology, and more specifically, to a process device for preparing USP low-temperature rubber asphalt modifier. Background Technology
[0002] USP Low-Temperature Rubber Asphalt Modifier, also known as USP Polymer Low-Temperature Asphalt Modifier, is an asphalt modifier made from waste rubber, plastics, long and short fibers and other waste polymer materials as main raw materials, polymer resins, crosslinking agents, catalysts and other materials through scientific formulation and special processes.
[0003] Currently, the batching process involves mixing various raw materials in specific proportions to allow the modifier and asphalt to interact better. For example, through proper batching, the polymer segments in the USP low-temperature rubber asphalt modifier can connect with the asphalt molecular chains, enhancing the bonding effect and reducing the viscosity of the asphalt during mixing. However, during the batching process, incompletely decomposed solid particles and fibrous impurities often remain in the pyrolysis products of waste polymer materials. Traditional equipment lacks targeted filtration and separation structures, causing these impurities to directly enter the batching system. The presence of impurities not only disrupts the precise ratio balance of raw materials but also hinders the effective binding of polymer segments and asphalt molecules, weakening the modification effect and even causing problems such as segregation and cracking of asphalt mixtures during use. Therefore, this paper provides a batching process device for the USP low-temperature rubber asphalt modifier. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a USP low-temperature rubber asphalt modifier batching process device, which aims to solve the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: a USP low-temperature rubber asphalt modifier batching process device, including a base, on which a batching component is provided;
[0006] The ingredient dispensing assembly includes an ingredient box disposed on the top of the base, a filter plate disposed in the middle of the ingredient box, a first ingredient dispensing chamber disposed on one side of the filter plate, and a second ingredient dispensing chamber disposed on the other side of the filter plate;
[0007] The base has two mounting cavities, and each mounting cavity is located at the bottom of the first and second feeding cavities respectively. A rotating rod is provided in each of the two mounting cavities, and each rotating rod has several material discharge holes through it.
[0008] A stirring shaft is provided in the first and second batching chambers respectively.
[0009] Optionally, in a possible implementation, the top of the base has two frame openings, and each frame opening is located at the bottom of the first and second batching chambers and communicates with the mounting chamber. The vertical cross-sectional shape of the discharge hole is set to L-shape, and the mounting chamber is opened along the length of the base. The bottom of the inner wall of the mounting chamber has several first discharge holes that extend to the bottom surface of the base. The side of the base has a second discharge hole that communicates with the mounting chamber. One end of the batching box is provided with a gearbox, and one end of each stirring shaft passes through the batching box and extends to the gearbox. A first motor is provided on the outside of the gearbox, and two second motors are provided at the bottom of the gearbox. Each rotating rod is detachably connected to the output end of the corresponding second motor.
[0010] The technical effects and advantages of this utility model are as follows:
[0011] By setting a filter plate in the middle of the batching box, impurities can be filtered simultaneously during the material mixing process. This directly intercepts incompletely pyrolyzed particles, fibers, and other impurities remaining in the raw materials, preventing impurities from entering the subsequent mixing system. This solves the problem of declining batching quality caused by the inability to divert impurities in existing devices from the source, and ensures the purity of the modifier components.
[0012] By using a rotating rod with an L-shaped discharge hole in conjunction with a second motor, the material discharge rate and timing can be precisely controlled by adjusting the rotation angle and speed of the rotating rod, avoiding material accumulation or uneven discharge. This solves the problem of uncontrolled material conveying affecting the accuracy of the proportioning in traditional batching, and ensures that the raw materials are fully utilized according to the preset proportion.
[0013] Furthermore, the mixing and filtration processes are integrated into the same batching chamber. During the mixing process, the materials are screened simultaneously, eliminating the need for additional terminal filtration. This reduces the adsorption loss of effective components and improves the overall process efficiency, thus solving the problem of insufficient synergy between mixing and filtration in existing devices.

[0020] 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.
[0021] This embodiment discloses a USP low-temperature rubber asphalt modifier batching process apparatus, which aims to solve the problem in the prior art that it is not easy to filter the materials during processing in the USP low-temperature rubber asphalt modifier batching process, resulting in the inability to divert impurities generated by the batching reaction, thereby reducing the quality of the batching process.
[0022] Specifically, the USP low-temperature rubber asphalt modifier batching process device includes a base 1, on which a batching component is installed. The batching component is the core structure for realizing material batching, filtration and discharge.
[0023] The batching assembly includes a batching box 2 fixedly installed on the top of the base 1. A filter plate 3 is horizontally fixed in the middle of the batching box 2. The filter plate 3 divides the internal space of the batching box 2 into an independent first batching chamber 4 and a second batching chamber 5. The filter plate 3 can perform preliminary filtration on the material entering the batching chamber and intercept large particulate impurities in the material.
[0024] Two mounting cavities 6 are formed along the length of the base 1, and each mounting cavity 6 is located directly below the first batching cavity 4 and the second batching cavity 5. Two frame openings 7 are formed on the top of the base 1, and each frame opening 7 is located at the bottom of the first batching cavity 4 and the second batching cavity 5 and is connected to the mounting cavity 6. The size of the frame opening 7 is adapted to the size of the bottom opening of the batching cavity to ensure that the material in the batching cavity can smoothly pass through the frame opening 7 into the mounting cavity 6.
[0025] Both mounting cavities 6 have horizontally arranged rotating rods 8, the outer diameter of which matches the inner diameter of the mounting cavity 6, allowing for stable rotation within the cavity. Each rotating rod 8 has several discharge holes 9 extending through it. The vertical cross-sectional shape of the discharge holes 9 is L-shaped, effectively controlling the material's falling speed and preventing material accumulation. The bottom of the inner wall of the mounting cavity 6 has several first discharge holes 10 extending to the bottom surface of the base 1. The side of the base 1 has a second discharge hole 11 communicating with the mounting cavity 6. Both the first discharge holes 10 and the second discharge holes 12 can be used to discharge processed materials. Depending on the actual material distribution requirements, a single discharge hole or simultaneous discharge from both holes can be selected.
[0026] A stirring shaft 15 is respectively installed in the first batching chamber 4 and the second batching chamber 5. Several stirring blades are fixedly sleeved on the stirring shaft 15. The stirring blades can adopt a spiral structure to fully stir the materials in the chamber and promote uniform mixing. A gearbox 12 is fixedly installed at one end of the batching box 2, and one end of each stirring shaft 15 passes through the side wall of the batching box 2 and extends into the gearbox 12, where it is connected to the gears. A first motor 13 is fixedly installed on the outside of the gearbox 12, and the output end of the first motor 13 is connected to the input shaft of the gearbox 12 to provide power for the rotation of the stirring shaft 15.
[0027] Two second motors 14 are fixedly installed at the bottom of the gearbox 12, and the end of each rotating rod 8 away from the gearbox 12 is detachably connected to the output end of the corresponding second motor 14 through a coupling, which facilitates the disassembly, maintenance and replacement of the rotating rod 8. The second motor 14 can drive the rotating rod 8 to rotate in the mounting cavity 6. By adjusting the rotation angle of the rotating rod 8, the communication state between the discharge hole 9 and the frame opening 7, the first discharge hole 10 and the second discharge hole 11 can be controlled, thereby realizing the control of material discharge.
[0028] The specific working principle is as follows: When preparing the USP low-temperature rubber asphalt modifier, different types of raw materials are first added to the first batching chamber 4 and the second batching chamber 5 respectively. The first motor 13 is started, and the first motor 13 drives the two stirring shafts 15 to rotate synchronously through the gearbox 12. The spiral stirring blades on the stirring shafts 15 thoroughly stir the raw materials in the chamber, promoting uniform mixing. During the stirring process, fine particles in the material can be preliminarily screened through the filter holes of the filter plate 3, while large particles of impurities are intercepted above the filter plate 3, achieving preliminary separation of impurities from the material and effectively preventing impurities from participating in subsequent reactions and affecting the batching quality.
[0029] The mixed material enters the mounting cavity 6 through the frame opening 7. The second motor 14 is then started, driving the rotating rod 8 to rotate. When the L-shaped discharge hole 9 on the rotating rod 8 aligns with the frame opening 7, the material enters the discharge hole 9. As the rotating rod 8 continues to rotate, the discharge hole 9 gradually aligns with either the first discharge hole 10 or the second discharge hole 11, and the material is discharged out of the device through the discharge hole, completing the batching process. During the discharge process, the rotation speed of the rotating rod 8 can be adjusted by controlling the speed of the second motor 14, thereby controlling the material discharge rate to meet different batching requirements.
[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
