Abstract
Description
Technical Field
[0001] The invention relates to the technical field of construction material mixing, and in particular to a production device for waste plastic particle reinforced asphalt mixture and a use method thereof. Background Art
[0002] Waste plastics can be added to asphalt mixtures, but waste plastics are not the main material, but are used as additives. Waste plastics can be added to asphalt through modification technology to improve the performance of asphalt and extend the service life of roads. Specifically, waste plastics such as polyethylene and polypropylene can be processed through twin-screw extrusion partition feeding and granulation technology to produce modifiers with stable performance, which are then added to asphalt mixtures. This modified asphalt mixture has improved low-temperature performance and high-temperature storage stability, and can reduce the cost of waste plastic processing and the cost of transportation infrastructure construction. It has been widely used in the construction of roads and bridges.
[0003] The application of existing production equipment for waste plastic granule reinforced asphalt mixture is understood: Common feeding devices usually require multiple motors to drive different feeding channels respectively, which not only increases the cost and energy consumption of the equipment, but also the coordinated work of multiple motors is also difficult, and it is easy to have asynchronous feeding and low efficiency. In addition, the feeding device may have problems such as material residue and blockage during operation, affecting the continuity of production.
[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a production device and a method for using a waste plastic particle reinforced asphalt mixture are provided, in order to achieve a more practical purpose. Summary of the invention
[0005] In order to solve the above technical problems, the present invention provides a production device for waste plastic particle reinforced asphalt mixture and a use method thereof, so as to solve the problem that the existing feeding device usually requires multiple motors to drive different feeding channels respectively, which not only increases the cost and energy consumption of the equipment, but also the coordinated work of multiple motors is also difficult, and it is easy to have asynchronous feeding and low efficiency. In addition, the feeding device may have problems such as material residue and blockage during operation, affecting the continuity of production.
[0006] The present invention provides a production device for waste plastic particle-reinforced asphalt mixture and its usage method, specifically including: an equipment frame; above the interior of the equipment frame, a mixing tank is installed. At the lower front position of the mixing tank, a rectangular groove is provided. At the top position of the mixing tank, an adding frame is provided in communication. Inside the adding frame, a U-shaped frame is fixedly installed. At the middle position of the rear end of the U-shaped frame, a motor B is fixedly installed. The front rotating shaft of the motor B is fixedly connected to a bevel gear part, and the bevel gear part is located at the rear end inside the U-shaped frame. On the left and right sides inside the U-shaped frame, a bevel gear cylinder part is rotatably connected respectively. The two bevel gear cylinder parts are symmetrically designed and both mesh with the bevel gear part. The interiors of the two bevel gear cylinder parts are through-designed, and a spiral frame is installed inside the two bevel gear cylinder parts. On the left and right sides of the adding frame, a feeding cylinder is fixedly installed respectively. The bottom positions of the two feeding cylinders are semi-circular designs, and the interiors of the feeding cylinders are hollow structure designs. The two spiral frames are respectively located at the lower semi-circular positions inside one feeding cylinder, and covers can be installed above the feeding cylinders.
[0007] Further, four bases are provided at the bottom position of the equipment frame. At the bottom position of each base, a height-adjustable support leg is provided, and a universal wheel is provided at the bottom position of each base.
[0008] Further, a notch is provided at the lower middle position of the front end of the equipment frame, and the notch of the equipment frame is located at the front end position of the rectangular groove of the mixing tank. At the front end position outside the notch of the equipment frame, a discharge hopper is fixedly installed.
[0009] Further, a placement table is provided at the upper middle position of the front end of the equipment frame, and a cylinder is installed at the upper middle position of the front end of the equipment frame. The placement table is located at the front end position of the cylinder.
[0010] Further, a baffle is provided at the bottom position of the cylinder. The baffle is located directly above the discharge hopper. When the cylinder is in the extended state, the baffle is located at the front end position of the rectangular groove of the mixing tank.
[0011] Further, a motor A is fixedly installed at the middle position of the rear end of the mixing tank. The front end of the rotating shaft of the motor A is fixedly connected to the rear end position of the mixing frame, and the mixing frame is located at the middle position inside the mixing tank.
[0012] The present invention also discloses a usage method for the production device of waste plastic particle-reinforced asphalt mixture, including the following steps:
[0013] (1), Move the production device to a suitable working site. By adjusting the height-adjustable support legs on the four bases at the bottom of the equipment frame, lift the bottom position of the universal wheels off the ground to prevent the equipment from moving during operation and make the equipment in a horizontal and stable state. During adjustment, observe the equipment to judge the horizontal situation to ensure that the support legs are in full contact with the ground and provide stable support;
[0014] (2) During feeding, appropriate amounts of raw materials required for production, such as waste plastic particles and asphalt, are proportionally fed into the two feeding cylinders. After the feeding is completed, the upper cover plates of the feeding cylinders are promptly closed to prevent impurities such as dust from entering the feeding cylinders;
[0015] (3) Start motor B. The front rotating shaft of motor B drives the bevel gear component to rotate. Since both bevel gear cylinder components are engaged with the bevel gear component and are symmetrically designed, the rotation of the bevel gear component will drive the two bevel gear cylinder components to rotate synchronously. As the bevel gear cylinder components rotate, the spiral frames installed inside them also rotate together. The rotation of the spiral frames transports the raw materials in the feeding cylinders into the installation frame and finally falls into the mixing tank. Since the bottom of the feeding cylinder is semi-circularly designed, the spiral frames can effectively push the raw materials at the bottom. The two feeding cylinders are respectively used for adding waste plastics and asphalt materials. The bevel gear component at the front end of motor B cooperates with the two bevel gear cylinder components, enabling the materials inside the two feeding cylinders to be transferred by the two spiral frames, reducing the motor occupancy and lowering the cost;
[0016] (4) After the raw materials enter the mixing tank, start motor A. The rotating shaft of motor A drives the mixing frame to rotate at the middle position inside the mixing tank, which can stir and mix the raw materials such as waste plastic particles and asphalt entering the mixing tank in all directions. During the mixing process, the rotation speed of motor A can be adjusted according to actual needs, thereby adjusting the mixing speed of the mixing frame to achieve the best mixing effect and enabling the waste plastic particles and asphalt to be fully mixed to form enhanced asphalt mixture;
[0017] (5) When the mixture is evenly stirred and mixed in the mixing tank, control the cylinder to contract. When the cylinder is in the contracted state, the baffle slides upward to disengage from the occlusion of the front position of the rectangular groove of the mixing tank. The enhanced asphalt mixture of waste plastic particles flows out through the rectangular groove of the mixing tank under the action of its own gravity, enters the discharge hopper through the notch below the middle of the front end of the equipment frame. The discharge hopper can guide the mixture to flow out smoothly, prevent it from accumulating in the discharge hopper, and facilitate its transfer to the corresponding container or transportation equipment for subsequent construction or processing.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] The feeding system of this device uses two feeding cylinders respectively for adding waste plastics and asphalt materials. Through the cooperation of the bevel gear component at the front end of motor B and the two bevel gear cylinder components, the materials are transferred by the two spiral frames. This design reduces the motor occupancy, lowers the equipment cost and energy consumption, and at the same time ensures the synchronism and stability of the two feeding channels, improves the feeding efficiency. In addition, the semi-circular design of the bottom of the feeding cylinder and the cooperation of the spiral frames can effectively push the raw materials at the bottom, reduce the possibility of material residue and blockage, and ensure the continuity of production.
[0020] The present invention can perform all-round stirring and mixing of raw materials such as waste plastic particles and asphalt by arranging a mixing rack in the mixing tank and driving its rotation by motor A. At the same time, the rotation speed of motor A can be flexibly adjusted according to actual needs to achieve the best mixing effect, so that the waste plastic particles and asphalt are fully mixed, effectively enhancing the performance of the asphalt mixture, improving its strength, durability, etc., and meeting the high-quality requirements of modern road engineering.
[0021] The design of the discharge hopper can guide the mixture to flow out smoothly, avoid accumulation in the discharge hopper, improve the smoothness of discharging and production efficiency, reduce the cleaning cost and time, and is beneficial to subsequent construction or processing operations. During the discharging process of the mixing tank, the mixing rack continues to rotate to accelerate the discharge of the raw materials inside the mixing tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Example:
[0036] As attached Figure 1 To Attachment Figure 6 As shown:
[0037] The present invention provides a production device and a usage method thereof for waste plastic particle-reinforced asphalt mixture, including: an equipment frame 1; a mixing tank 2 is installed above the interior of the equipment frame 1. A rectangular groove is formed at the lower front position of the mixing tank 2. A through loading frame 201 is arranged at the top position of the mixing tank 2. A U-shaped frame 204 is fixedly installed inside the loading frame 201. A motor B 205 is fixedly installed at the middle rear position of the rear end of the U-shaped frame 204. The front rotating shaft of the motor B 205 is fixedly connected to a bevel gear part 206. The bevel gear part 206 is located at the rear end inside the U-shaped frame 204. A bevel gear cylinder part 208 is rotatably connected to each of the left and right sides inside the U-shaped frame 204. The two bevel gear cylinder parts 208 are symmetrically designed and both mesh with the bevel gear part 206. The interiors of the two bevel gear cylinder parts 208 are through-designed, and a spiral frame 209 is installed inside the two bevel gear cylinder parts 208. A feeding cylinder 207 is fixedly installed on each of the left and right sides of the loading frame 201. The bottom positions of the two feeding cylinders 207 are semi-circular designs, and the interiors of the feeding cylinders 207 are hollow structure designs. The two spiral frames 209 are respectively located at the lower semi-circular positions inside one feeding cylinder 207. Covers can be installed at the upper ends of the feeding cylinders 207.
[0038] Among them, four bases 101 are arranged at the bottom position of the equipment frame 1. An adjustable-height support leg 102 is arranged at the bottom position of each base 101. A universal wheel 103 is arranged at the bottom position of each base 101.
[0039] Among them, a notch is formed at the lower middle front position of the equipment frame 1, and the notch of the equipment frame 1 is located at the front end position of the rectangular groove of the mixing tank 2. A discharge hopper 104 is fixedly installed at the front end outer side position of the notch of the equipment frame 1. A placement table 105 is arranged at the upper middle front position of the equipment frame 1, and a cylinder 106 is installed at the upper middle front position of the equipment frame 1. The placement table 105 is located at the front end position of the cylinder 106. A baffle 107 is arranged at the bottom position of the cylinder 106. The baffle 107 is located directly above the discharge hopper 104. When the cylinder 106 is in the extended state, the baffle 107 is located at the front end position of the rectangular groove of the mixing tank 2.
[0040] Among them, a motor A 202 is fixedly installed at the middle rear position of the rear end of the mixing tank 2. The front end of the rotating shaft of the motor A 202 is fixedly connected to the rear end position of the mixing frame 203. The mixing frame 203 is located at the middle position inside the mixing tank 2.
[0041] During use:
[0042] Move the production device to a suitable working site. By adjusting the height-adjustable support legs 102 on the four bases 101 at the bottom of the equipment rack 1, move the bottom position of the universal wheels 103 away from the ground to prevent the equipment from moving during operation and keep the equipment in a horizontal and stable state. During adjustment, observe the equipment to judge the level situation to ensure that the support legs 102 are in full contact with the ground and provide stable support.
[0043] During feeding, proportionally put appropriate amounts of raw materials required for production, such as waste plastic particles and asphalt, into the two feeding cylinders 207 respectively. After the feeding is completed, promptly close the upper cover plates of the feeding cylinders 207 to prevent impurities such as dust from entering the feeding cylinders 207.
[0044] Start the motor B205. The front rotating shaft of the motor B205 drives the bevel gear part 206 to rotate. Since both bevel gear cylinders 208 are engaged with the bevel gear part 206 and are symmetrically designed, the rotation of the bevel gear part 206 will drive the two bevel gear cylinders 208 to rotate synchronously. With the rotation of the bevel gear cylinders 208, the spiral racks 209 installed inside them also rotate together. The rotation of the spiral racks 209 transports the raw materials in the feeding cylinders 207 into the installation rack 201 and finally falls into the mixing tank 2. Since the bottom of the feeding cylinder 207 is semicircularly designed, the spiral racks 209 can effectively push the raw materials at the bottom. The two feeding cylinders 207 are respectively used for adding waste plastics and adding asphalt materials. The bevel gear part 206 at the front end of the motor B205 cooperates with the two bevel gear cylinders 208, enabling the materials inside the two feeding cylinders 207 to be transferred by the two spiral racks 209, reducing the motor occupancy and lowering the cost.
[0045] After the raw materials enter the mixing tank 2, start the motor A202. The rotating shaft of the motor A202 drives the mixing rack 203 to rotate at the middle position inside the mixing tank 2, which can stir and mix the raw materials such as waste plastic particles and asphalt entering the mixing tank 2 in all directions. During the stirring process, the rotation speed of the motor A202 can be adjusted according to actual needs, so as to adjust the stirring speed of the mixing rack 203 to achieve the best mixing effect and make the waste plastic particles and asphalt fully mixed to form an enhanced asphalt mixture.
[0046] After the mixture is stirred and mixed evenly in the mixing tank 2, control the cylinder 106 to contract. When the cylinder 106 is in the contracted state, the baffle 107 slides upward to disengage from the occlusion of the front position of the rectangular groove of the mixing tank 2. Under the action of its own gravity, the waste plastic particle reinforced asphalt mixture flows out through the rectangular groove of the mixing tank 2, enters the discharge hopper 104 through the notch below the middle of the front end of the equipment frame 1, and the discharge hopper 104 can guide the mixture to flow out smoothly, avoiding accumulation in the discharge hopper 104 and facilitating transfer to the corresponding container or transportation equipment for subsequent construction or processing. The above is only the specific implementation manner of the present disclosure, but the protection scope of the present disclosure is not limited thereto. The protection scope of the present disclosure shall be subject to the protection scope of the claims.

7. The method for using the waste plastic granule reinforced asphalt mixture production device as described in claims 1-6 is characterized in that: The following steps are involved: (1) Move the production device to a suitable work site, adjust the height-adjustable support legs (102) on the four bases (101) at the bottom of the equipment frame (1), and lift the bottom of the universal wheel (103) off the ground to prevent the device from moving during operation, so that the device is in a horizontal and stable state. During adjustment, observe the equipment to determine the horizontal state, and ensure that the support legs (102) are in full contact with the ground and provide stable support; (2) When loading materials, appropriate amounts of waste plastic particles and asphalt and other raw materials required for production are respectively added to the two loading barrels (207) in proportion. After the loading is completed, the upper cover of the loading barrel (207) is closed in time to prevent dust and other impurities from entering the loading barrel (207); (3) Start the motor B (205), the front end shaft of the motor B (205) drives the bevel gear (206) to rotate. Since the two bevel gear cylinders (208) are meshed with the bevel gear (206) and are symmetrically designed, the rotation of the bevel gear (206) drives the two bevel gear cylinders (208) to rotate synchronously. As the bevel gear cylinder (208) rotates, the spiral frame (209) installed inside the bevel gear cylinder (208) also rotates. The rotation of the spiral frame (209) transports the raw materials in the loading barrel (207) into the loading barrel. The rack (201) is loaded and finally falls into the mixing tank (2). Since the bottom of the upper barrel (207) is designed as a semicircle, the spiral rack (209) can effectively push the raw materials at the bottom. The two upper barrels (207) are used for adding waste plastics and asphalt materials respectively. The bevel gear (206) at the front end of the motor B (205) cooperates with the two bevel gear cylinders (208), so that the materials inside the two upper barrels (207) are transferred by the two spiral racks (209), which reduces the motor occupation and reduces the cost. (4) After the raw materials enter the mixing tank (2), the motor A (202) is started, and the rotating shaft of the motor A (202) drives the mixing frame (203) to rotate in the middle position of the mixing tank (2), so as to stir and mix the waste plastic particles and asphalt and other raw materials entering the mixing tank (2) in an all-round manner. During the stirring process, the rotation speed of the motor A (202) can be adjusted according to actual needs, thereby adjusting the stirring speed of the mixing frame (203) to achieve the best mixing effect, so that the waste plastic particles and the asphalt are fully mixed to form an enhanced asphalt mixture; (5) After the mixture is stirred and mixed evenly in the mixing tank (2), the cylinder (106) is controlled to contract. When the cylinder (106) is in the contracted state, the baffle (107) slides upward to disengage from the obstruction of the front end of the rectangular groove of the mixing tank (2). Under the action of its own gravity, the asphalt mixture reinforced with waste plastic particles flows out through the rectangular groove of the mixing tank (2) and enters the discharge hopper (104) through the gap in the middle and lower front end of the equipment frame (1). The discharge hopper (104) can guide the mixture to flow out smoothly, avoid accumulation in the discharge hopper, and facilitate transfer to corresponding containers or transportation equipment for subsequent construction or processing.
