Description

Technical Field

[0001] This utility model relates to the field of asphalt production technology, specifically to a rubber-modified asphalt production device. Background Technology

[0002] Rubber-modified asphalt is an asphalt binder made by adding external admixtures (modifiers) such as rubber, resin, polymer, finely ground rubber powder or other fillers, or by taking measures such as light oxidation processing of asphalt to improve the performance of asphalt or asphalt mixture. Modified asphalt needs to be obtained by mixing and heating the materials in a mixer.

[0003] When adding modifiers or fillers to asphalt, if the moisture content of the modifiers or fillers is too high, it will lead to poor dispersion of the material in the asphalt, resulting in clumping. In addition, the asphalt itself will also clump or agglomerate during the production process. Simply relying on a mixer cannot remove the clumps, which can easily affect the product quality. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model proposes a rubber-modified asphalt production device to solve the above problems.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] This utility model provides a rubber-modified asphalt production apparatus, comprising:

[0007] A mixing tank is provided with a feed inlet at the top and a discharge outlet at the bottom. A strainer plate is installed inside the mixing tank. The strainer plate has multiple leakage holes. An annular track is provided on the top edge of the strainer plate. Multiple grooves are provided on the annular track.

[0008] A compaction mechanism includes a motor, a main shaft, and a movable shaft. The motor is mounted on the top of the mixing tank. The main shaft is rotatably mounted on the top of the inner cavity of the mixing tank, with its top end connected to the output shaft of the motor and its bottom end provided with a sliding pin. A pressure block is provided at the bottom end of the movable shaft, which is located above the sluice plate. A support rod is provided on one side of the movable shaft, with its distal end extending radially to the top of the annular track. A bushing is provided at the top of the movable shaft, which slides up and down into the bottom end of the sliding pin. A first spring is connected between the bushing and the bottom end of the main shaft to provide elastic force so that the support rod abuts against the top of the annular track. When the support rod abuts against the groove, the pressure block abuts against the top surface of the sluice hole.

[0009] The mixing mechanism is installed inside the mixing tank and located above the baffle plate.

[0010] Furthermore, the surface of the perforated plate is recessed downwards with its center as the base point, and the bottom surface of the pressing block is adapted to the shape of the top surface of the perforated plate.

[0011] Furthermore, a roller is provided at the bottom of the support rod, and the roller abuts against the top of the annular track.

[0012] Furthermore, the bottom end of the movable shaft movably passes through the bottom of the sprue and is provided with a bottom post. A sliding ring is slidably fitted on the outside of the bottom post, and a scraper is installed on the sliding ring. A second spring is connected between the sliding ring and the bottom post to provide elastic force to move the sliding ring upward and make the scraper abut against the bottom surface of the sprue.

[0013] Furthermore, the stirring mechanism includes a first gear and two stirring rods. The first gear is mounted on the top of the main shaft, and the two stirring rods are rotatably mounted on the top of the inner cavity of the stirring box and located on both sides of the main shaft. A second gear that meshes with the first gear is mounted on the stirring rod, and stirring blades are provided at the bottom of the stirring rod.

[0014] Furthermore, a partition is installed in the inner cavity of the mixing tank below the first gear and the second gear, and the main shaft and the two stirring rods movably pass through the partition.

[0015] As can be seen from the above technical solution, this utility model provides a rubber-modified asphalt production device:

[0016] The motor drives the main shaft and movable shaft to rotate, and the elastic force of the first spring causes the support rod to repeatedly enter the groove on the path of the circular track. This causes the pressure block to move up and down repeatedly, so that the material flows continuously to the sluice plate and is continuously crushed by the pressure block to break up the clumps of material. The refined material then flows down through the sluice hole for subsequent processing, which helps to improve the product quality of modified asphalt. Attached Figure Description

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0027] like Figure 1-2 As shown, this embodiment provides a rubber-modified asphalt production apparatus, which includes a mixing tank 1, a rolling mechanism 2, and a mixing mechanism 3.

[0028] The mixing tank 1 has an inlet 11 at the top and an outlet 12 at the bottom. A strainer 13 is installed inside the mixing tank 1. The strainer 13 is located between the inlet 11 and the outlet 12. The strainer 13 has multiple holes 131. The top edge of the strainer 13 has an annular track 14 with multiple grooves 141.

[0029] The compaction mechanism 2 includes a motor 21, a main shaft 22, and a movable shaft 23. The motor 21 is mounted on the top of the mixing tank 1, with its output shaft end extending downwards into the top of the inner cavity of the mixing tank 1. The main shaft 22 is rotatably mounted on the top of the inner cavity of the mixing tank 1, with its top end connected to the output shaft of the motor 21 and its bottom end equipped with a sliding pin 221. A pressure block 231 is provided at the bottom end of the movable shaft 23, located above the sluice plate 13. A support rod 232 is provided on one side of the movable shaft 23, with its distal end extending radially above the annular track 14. A bushing 233 is provided at the top of the movable shaft 23. The bushing 233 is slidably inserted into the bottom of the sliding pin 221. Preferably, the sliding pin 221 is a cross-shaped pin. The inner wall of the bushing 233 is adapted to the shape of the sliding pin 221 so that the main shaft 22 can drive the movable shaft 23 to rotate synchronously. A first spring 234 is connected between the bushing 233 and the bottom of the main shaft 22 to provide elastic force so that the support rod 232 abuts against the top of the annular track 14. When the support rod 232 abuts against the groove 141, the pressure block 231 will abut against the top surface of the leakage hole 131.

[0030] Preferably, a roller 235 is provided at the bottom of the support rod 232, and the roller 235 abuts against the top of the annular track 14, which helps to reduce the frictional resistance between the support rod 232 and the annular track 14.

[0031] The stirring mechanism 3 is installed inside the mixing tank 1 and located above the sluice plate 13.

[0032] Specifically, the stirring mechanism 3 includes a first gear 31 and two stirring rods 32. The first gear 31 is installed at the top of the main shaft 22, and the two stirring rods 32 are respectively rotatably installed at the top of the inner cavity of the mixing box 1 and located on both sides of the main shaft 22. A second gear 33 that meshes with the first gear 31 is installed on the stirring rod 32, and a stirring blade 34 is provided at the bottom of the stirring rod 32. When the main shaft 22 rotates, it can drive the two stirring rods 32 to rotate synchronously through the first gear 31 and the second gear 33, so that the stirring rods 32 can stir the material, which is conducive to the simultaneous operation of stirring the material and crushing the agglomerated material.

[0033] Furthermore, a partition 15 is installed in the inner cavity of the mixing tank 1 below the first gear 31 and the second gear 33. The main shaft 22 and the two stirring rods 32 both move through the partition 15 to separate the material from the first gear 31 and the second gear 33, preventing the material from sticking and interfering with the transmission between the main shaft 22 and the stirring rods 32. It should be noted that the feed inlet is located below the partition 15.

[0034] In practical use, the material enters the inner cavity of the mixing tank 1 located above the sluice plate 13 through the inlet 11 and is stirred by the stirring mechanism 3. At the same time, the motor 21 is started to drive the main shaft 22 and the movable shaft 23 to rotate, so that the support rod 232 rotates against the top surface of the annular track 14. When the support rod 232 is not in the groove 141, the pressure block 231 will move away from the sluice plate 13, so that the material flows between the pressure block 231 and the sluice plate 13. When the support rod 232 moves to the groove 141, the pressure block 231 will approach the top surface of the sluice hole 131 and squeeze the material therein. The material is squeezed and refined from each sluice hole 131 and falls to the bottom of the inner cavity of the mixing tank 1, and is conveyed out from the outlet 12. This invention utilizes a motor 21 to drive the main shaft 22 and the movable shaft 23 to rotate, and through the elastic force of the first spring 234, the support rod 232 repeatedly enters the groove 141 on the path of the annular track 14, thereby causing the pressure block 231 to move up and down repeatedly, so that the material continuously flows to the sluice plate 13 and is continuously crushed by the pressure block 231 to break up the clumps of material, and the refined material falls through the sluice hole 131 for subsequent processing, which is beneficial to improving the product quality of modified asphalt.

[0035] Preferably, the surface of the sluice plate 13 is concave downward with its center as the base point, and the bottom surface of the pressure block 231 is adapted to the shape of the top surface of the sluice plate 13, which is conducive to the material being better concentrated and flowing onto the sluice plate 13.

[0036] In one embodiment, the bottom end of the movable shaft 23 movably passes through the bottom of the sprue plate 13 and is provided with a bottom post 24. A sliding ring 241 is slidably fitted on the outside of the bottom post 24. A scraper 242 is installed on the sliding ring 241. A second spring 243 is connected between the sliding ring 241 and the bottom post 24 to provide elastic force to move the sliding ring 241 upward and make the scraper 242 abut against the bottom surface of the sprue plate 13. The bottom post 24, the sliding ring 241 and the scraper 242 can rotate synchronously with the movable shaft 23 so that the scraper 242 can scrape off the material attached to the bottom surface of the sprue plate 13.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of this utility model, and they should all be covered within the scope of the claims and description of this utility model.
