The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] like Figure 1 and Figure 2 The asphalt mixture quantitative addition basalt fiber production equipment shown in the figure includes a support frame 10, a mixing chamber 20 fixedly arranged on the support frame 10, and a quantitative addition component 30, a first feed bin 40 and a stirring control component 50 arranged on the mixing chamber 20 and facing the inside of the mixing chamber 20; a discharge port 60 is arranged at the bottom of the mixing chamber 20;

[0030] The quantitative addition component 30 includes a feed barrel 31, a weighing component 32 and a rotating motor 33. A second feed bin 34 is arranged on the top of the feed barrel 31, and the bottom of the feed barrel 31 faces the mixing chamber 20. The weighing component 32 is arranged at the lower part of the second feed bin 34 and is rotatably connected to the feed barrel 31. The rotating motor 33 drives the weighing component 32 to flip. The accurate measurement and automatic addition of basalt fiber are realized, which reduces the steps of manual operation and improves production efficiency. The combined use of the weighing component 32 and the rotating motor 33 ensures the precise control of the addition amount of basalt fiber, thereby ensuring the accurate ratio of each component in the asphalt mixture and improving the quality stability of the mixture.

[0031] The stirring control assembly 50 includes a stirring motor 51 and a first rotating shaft 52. The stirring motor 51 is fixed at the top of the mixing chamber 20. The first rotating shaft 52 is arranged at the bottom of the stirring motor 51 and extends into the mixing chamber 20. A spiral stirring paddle 53 and an arc-shaped scraper 54 are arranged on the outer diameter of the first rotating shaft 52. The materials in the mixing chamber 20 can be fully and evenly mixed, the fiber agglomeration and uneven distribution are prevented, and the uniformity and performance of the asphalt mixture are improved.

[0032] The utility model sets a weighing component 32 inside the device, so that the weighing process of basalt fiber is not disturbed by the outside world, the weighing result is accurate, and the operation is simple and convenient; at the same time, the electronic control system 26 is set to facilitate the quantitative feeding of basalt fiber, heating and stirring of basalt fiber asphalt mixture, and discharging. The device integrates automatic weighing, automatic turning and automatic stirring functions, greatly reduces manual intervention, reduces labor intensity, improves the level of automation, and is suitable for large-scale continuous production.

[0033] Specific as Figure 2 As shown, the second rotating shaft 35 and the third rotating shaft 36 are fixedly connected on both sides of the weighing assembly 32; the third rotating shaft 36 is movably connected to the feeding barrel 31 on the side away from the weighing assembly 32, and the second rotating shaft 35 is fixedly connected to the rotating motor 33 on the side away from the weighing assembly 32. The arrangement of the second rotating shaft 35 and the third rotating shaft 36 makes the support of the weighing assembly 32 more stable during the flipping process, effectively prevents the shaking and deviation that may occur during the flipping process, and improves the reliability of the system operation. On this basis, the weighing error caused by vibration is reduced, thereby further improving the accuracy of basalt fiber addition and ensuring the precise control of the mixture ratio.

[0034] Specifically, the feed barrel body is divided into two parts, a cylindrical barrel body and a funnel-shaped barrel body, and the inner wall of the feed barrel body is smooth; the weighing assembly is arranged at the position of the cylindrical barrel body. The weighing assembly 32 is a box-type structure, including a high-precision electronic balance and a vibration plate arranged at the bottom of the high-precision electronic balance. The accurate measurement of the amount of basalt fiber added is ensured, the accuracy of the mixture ratio is further improved, and the quality and performance of the final product are guaranteed. The design of the vibration plate can prevent the accumulation or adhesion of the fiber material on the high-precision electronic balance when it falls into the mixing chamber 20 after the weighing is completed through appropriate vibration, thereby ensuring the smoothness and stability of the weighing process and improving the accuracy and efficiency of the weighing. In order to avoid the influence of the vibration plate on the weighing process, the vibration plate is closed during weighing.

[0035] Please continue to refer to Figure 2 The mixing chamber 20 includes an outer wall 21 and an inner wall 22, and heat transfer oil 23 is filled between the outer wall 21 and the inner wall 22. It can evenly conduct heat to ensure uniform temperature distribution in the mixing chamber 20, which is conducive to the full mixing of the asphalt mixture and the basalt fiber and prevents local overheating or overcooling. A heating resistance wire and a temperature sensor are arranged on the outer wall 21. The temperature sensor monitors the temperature change in the mixing chamber 20 in real time. By using it in conjunction with the heating resistance wire, accurate temperature regulation can be achieved to ensure that the mixture operates within the optimal temperature range and improve the mixing quality.

[0036] In order to ensure smooth mixing and discharge, the mixing chamber 20 is divided into two parts: a cylindrical barrel 24 and a funnel-shaped barrel 25; the spiral stirring paddle 53 includes a first propeller blade 531 and a second propeller blade 532. The first propeller blade 531 is placed in the cylindrical barrel 24, and the second propeller blade 532 is placed in the funnel-shaped barrel 25. The size of the first propeller blade 531 is larger than that of the second propeller blade 532. Preferably, the size of the second propeller blade 532 changes with the diameter of the funnel-shaped barrel 25. Specifically, Figure 2 The volume of the material decreases from top to bottom, ensuring that the materials are fully mixed in different areas and avoiding dead corners and uneven mixing. The design of the funnel-shaped barrel 25 is conducive to the gravity discharge of the material, and the stirring action of the second propeller blade 532 further promotes the flow of the material, making the discharge smoother and reducing residue and waste.

[0037] In the present invention, the large-sized first propeller blade 531 can effectively stir a large volume of material in the cylindrical barrel 24, increasing the coverage and speed of mixing; at the same time, it can effectively prevent the material from settling at the bottom, and make the material constantly turn up through strong stirring to ensure the uniform distribution of each component; the second propeller blade 532 in the funnel-shaped barrel 25 can prevent the material from accumulating at the bottom of the funnel, ensuring smooth material discharge. The small-sized second propeller blade 532 in the funnel-shaped barrel 25 can finely stir small and concentrated materials, improving the overall mixing efficiency.

[0038] Preferably, the arc scraper 54 is placed in the cylindrical barrel 24, and the arc scraper 54 is arranged in cooperation with the cylindrical barrel 24. The arc scraper 54 continuously scrapes the material on the barrel wall during the mixing process, so that the material is not easy to form a stagnation area on the barrel wall, thereby enhancing the circulation fluidity of the material and improving the overall mixing efficiency. The reduction of fluidity due to adhesion is avoided, ensuring a smooth and efficient mixing process.

[0039] like Figure 1 As shown, an electronic control system 26 including a display screen and a control console is provided outside the mixing chamber 20. Various parameters in the mixing chamber 20 can be monitored and adjusted in real time, thereby improving the intelligence level of the equipment and the convenience of operation.

[0040] like Figure 2 As shown, the discharge port 60 is provided with a solenoid valve 61. The discharge speed and time of the material can be accurately controlled, the uniformity and stability of the discharge are ensured, the error of manual operation is reduced, and the production efficiency and product quality are improved.

[0041] The utility model provides spiral stirring paddles 53 in both the cylindrical barrel body 24 and the funnel-shaped barrel body 25 in the mixing barrel body, so that the basalt fiber asphalt mixture is evenly stirred, and at the same time, an axial thrust can be provided to the basalt fiber asphalt mixture, so as to improve the smoothness of discharge and prevent the basalt fiber asphalt mixture from blocking the discharge port 60; at the same time, an arc scraper 54 is provided in the mixing barrel body to prevent the basalt fiber asphalt mixture from adhering to the inner wall 22 of the mixing barrel and causing uneven stirring; on this basis, a solenoid valve 61 is provided in the discharge port 60 to facilitate the stable discharge of the basalt fiber asphalt mixture after it is fully stirred.

[0042] Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the description are only for explaining the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which are within the scope of the present invention.
