Description

Technical Field

[0001] This utility model relates to the field of asphalt testing technology, specifically to a combustion asphalt analyzer based on the complete combustion method. Background Technology

[0002] Currently, asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a type of high-viscosity organic liquid, which is liquid with a black surface and is soluble in carbon disulfide. At the same time, it is used as a waterproof, moisture-proof and corrosion-resistant organic cementing material in many fields. Currently, the asphalt content is mostly tested using the combustion method, and a combustion method asphalt content analyzer has been designed.

[0003] Patent publication number CN217277619U, publication date 2022-08-23, provides a combustion-based asphalt content analyzer, including an analyzer body with a combustion chamber inside. The combustion chamber contains a clamping mechanism for holding a feeding box. The clamping mechanism includes two clamping components, each consisting of a U-shaped frame connected to the inner wall of the combustion chamber via a telescopic rod. A screw hole is located at the top of the U-shaped frame, with a screw threaded into it. A pressure plate is rotatably mounted at the bottom of the screw. Using this technical solution, asphalt is placed into the feeding box, which is then clamped within the clamping mechanism. The distance between the two clamping components can be adjusted via the telescopic rod, facilitating the clamping of feeding boxes of different sizes between the two U-shaped frames. By rotating the screw and using the pressure plate to fix the feeding box, the feeding box is clamped. A motor can rotate the feeding box, facilitating combustion of the asphalt on both sides within the box. This provides a combustion-based asphalt content analyzer that ensures complete combustion of asphalt.

[0004] The aforementioned patent uses a motor to rotate the discharge box, which facilitates combustion of the asphalt on both sides of the box. However, before conducting the asphalt combustion test, the discharge box needs to be preheated to a high temperature of 538°C. To achieve rotation, the box needs to be manually tightened with bolts, which is inconvenient and poses safety hazards in high-temperature environments. Secondly, the lack of a weighing device inside the analyzer means that the initial mass of the sample and discharge box must be weighed on a precision balance outside the analyzer before being sent to the combustion chamber for preheating and combustion. After combustion, the discharge box must be allowed to cool to room temperature before being transferred to the balance to weigh the total mass of the residual mineral powder and the discharge box. The asphalt content is calculated by the difference between the two weighings, which increases the risk of mass loss during sample transfer and makes it impossible to monitor mass changes in real time during combustion (as sample splashing occurs during combustion). These changes can only be detected when the box is cooled and weighed after combustion, leading to test failures, wasted samples and time, and seriously affecting the efficiency and accuracy of the test results.

[0005] Therefore, this invention provides a combustion method asphalt analyzer for complete combustion. Utility Model Content

[0006] To address the problem that existing systems can help asphalt burn completely but cannot monitor the asphalt combustion process in real time, or can monitor it in real time but cannot guarantee complete combustion, the purpose of this invention is to provide a combustion-based asphalt analyzer that ensures complete combustion.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fully combusted asphalt analyzer, comprising an asphalt analyzer body, a hinged door on one side of the asphalt analyzer body, a weighing scale installed inside the combustion chamber of the asphalt analyzer body, and an adjustment mechanism on the upper part of the asphalt analyzer body for assisting rapid asphalt combustion. The adjustment mechanism includes: The rotating assembly includes a bearing rotatably mounted on the upper part of the asphalt analyzer body, a rotating shaft slidingly mounted in the middle of the bearing, a drive assembly at the top of the rotating shaft, and a support frame fixedly mounted at the bottom of the rotating shaft. The lifting assembly, located on the other side of the upper part of the asphalt analyzer body, is used to adjust the height of the support frame; The limiting components are located on both sides of the lower part of the support frame and are used to limit the discharge box for storing asphalt.

[0008] Preferably, the lifting assembly includes a cylinder fixedly installed on one side of the upper part of the asphalt analyzer body, a connecting plate fixedly installed on the driving end of the cylinder, and the top end of the rotating shaft rotatably installed on one side of the bottom end of the connecting plate.

[0009] Preferably, the limiting component includes two limiting baffles disposed at the lower part of the support frame, two symmetrically distributed limiting springs are fixedly installed on one side of each of the two limiting baffles, and the other ends of the multiple limiting springs are fixedly installed on the lower side of the support frame.

[0010] Preferably, the drive assembly includes a drive motor fixedly installed on one side of the upper part of the asphalt analyzer body. The drive motor and the rotating shaft are connected by a synchronous belt and a synchronous pulley, and the upper part of the rotating shaft slides through the middle of the synchronous pulley on one side of the transmission belt.

[0011] Preferably, two symmetrically distributed drive blocks are fixedly installed on the outer side of the rotating shaft, and both drive blocks slide through the middle of the bearing and the synchronous pulley.

[0012] Preferably, two symmetrically distributed sleeves are fixedly installed on the opposite sides of the two limiting baffles, and the other ends of the two sleeves are fixedly installed on the lower part of one side of the limiting baffle.

[0013] Beneficial effects This invention provides a combustion-based asphalt analyzer for complete combustion. Compared with existing technologies, it has the following advantages: 1. This application uses a control system to start the cylinder and drive motor at a preset cycle. The cylinder drives the support frame to rise and detaches the discharge box from the weighing scale. Then, the drive motor drives the rotating shaft and discharge box to rotate slowly through synchronous belt transmission. This rotational motion continuously changes the spatial position of the material, allowing the material that was originally at the bottom to be fully exposed to the oxygen-rich combustion atmosphere. At the same time, it enhances the airflow disturbance in the cavity, greatly promoting the mixing efficiency of combustibles and air, thereby achieving rapid and complete combustion of asphalt.

[0014] 2. This application enables the combination of dynamic combustion process with real-time quality monitoring, ensuring the accuracy and continuity of measurement data without affecting the combustion effect. At the same time, the limit spring and inclined baffle structure ensure that the feeding box is always stably limited during lifting, rotation and descent, avoiding positional deviation of the feeding box during rotation that would lead to inaccurate weighing data.

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-6 This utility model provides a technical solution: a fully combusted asphalt analyzer using a combustion method, comprising an asphalt analyzer body 1, a hinged door 11 on one side of the asphalt analyzer body 1, a high-temperature resistant sealing strip installed on the inner side of the door 11, which can tightly fit against the side wall of the asphalt analyzer body 1 when closed to prevent leakage of high-temperature flue gas during combustion, and a heat-insulating handle on the outer side of the door 11 to prevent burns to the operator, a weighing scale 12 installed in the combustion chamber of the asphalt analyzer body 1, and an adjustment mechanism 2 provided on the upper part of the asphalt analyzer body 1 to assist in rapid combustion of asphalt, the adjustment mechanism 2 including: The rotating assembly 21 includes a bearing 212 rotatably mounted on the upper part of the asphalt analyzer body 1. A rotating shaft 213 is slidably mounted in the middle of the bearing 212. By mounting the rotating shaft 213 in the middle of the bearing 212, a drive block 214 can be mounted on the outer surface of the rotating shaft 213. At the same time, it can be sealed and connected to the asphalt analyzer body 1 without affecting the rotation. A drive assembly is provided at the top of the rotating shaft 213, and a support frame 215 is fixedly mounted at the bottom of the rotating shaft 213. By rotating the rotating shaft 213, the lower support frame 215 can be rotated, thereby driving the discharge box located on the support frame 215 to rotate. The lifting assembly 22 is located on the other side of the upper part of the asphalt analyzer body 1 and is used to adjust the height of the support frame 215. Limiting components 23 are installed on both sides of the lower part of the support frame 215 to limit the discharge box for storing asphalt.

[0024] The lifting assembly 22 includes a cylinder 221 fixedly installed on one side of the upper part of the asphalt analyzer body 1. A connecting plate 222 is fixedly installed on the driving end of the cylinder 221. The top end of the rotating shaft 213 is rotatably installed on one side of the bottom end of the connecting plate 222. The cylinder 221 is an SC125*400 cylinder. Under the upward drive of the cylinder 221, the connecting plate 222 can be moved upward. Under the transmission of the rotating shaft 213, the support frame 215 can be moved upward, so that the bottom ends of both sides of the discharge box contact the lower part of the support frame 215. As it continues to move upward, the discharge box is disengaged from the weighing system. The scale 12, under the rotation of the rotating shaft 213, drives the discharge box to rotate. By rotating, the spatial position of the burning asphalt inside can be adjusted, and the air inside the discharge box can be circulated to accelerate combustion. The drive motor 211 and the cylinder 221 work together. When the cylinder 221 finishes its work, the drive motor 211 starts to rotate. And through the control system setting, the discharge box is lifted and rotated for a certain period of time before being put back on the weighing scale 12. This helps the asphalt to burn quickly and completely without affecting the real-time monitoring of weight.

[0025] The limiting assembly 23 includes two limiting baffles 231 disposed at the lower part of the support frame 215. Two symmetrically distributed limiting springs 233 are fixedly installed on one side of each of the two limiting baffles 231. The other ends of the multiple limiting springs 233 are fixedly installed on the lower side of the support frame 215. The limiting baffles 231 are divided into upper and lower parts, with the upper part inclined outward. When the support frame 215 moves upward, the two limiting baffles 231 can move outward under the weight of the feeding box until the feeding box contacts the bottom upper surface of the support frame 215 and is limited by the force of the limiting springs 233.

[0026] The drive assembly includes a drive motor 211 fixedly installed on one side of the upper part of the asphalt analyzer body 1. The drive motor 211 and the rotating shaft 213 are connected to the synchronous pulley via a synchronous belt. The upper part of the rotating shaft 213 slides through the middle of the synchronous pulley on one side of the transmission belt. The drive motor 211 is a Delta ECMA series servo motor, model ECMA-C20807RS. Under the drive of the drive motor 211, the rotating shaft 213 can be rotated by the synchronous rotation of the synchronous belt and the synchronous pulley, which can be limited by the drive block 214.

[0027] Two symmetrically distributed drive blocks 214 are fixedly installed on the outer side of the rotating shaft 213. Both drive blocks 214 slide through the middle of the bearing 212 and the synchronous pulley. The drive blocks 214 enable the rotating shaft 213 to rotate through the limiting of the synchronous belt and the synchronous pulley when they rotate, thereby driving the bearing frame 215 to rotate. At the same time, it does not affect the cylinder 221 from driving the rotating shaft 213 to slide in the middle of its synchronous pulley, so that it can achieve the effect of moving up and down.

[0028] Two symmetrically distributed sleeves 232 are fixedly installed on opposite sides of the two limiting baffles 231. The other ends of the two sleeves 232 are fixedly installed on the lower part of one side of the limiting baffle 231. The sleeves 232 are divided into inner sleeves and outer sleeves, and the limiting spring 233 is located in the middle of the inner sleeve and the outer sleeve, so that the limiting spring 233 can be protected and prevented from being jammed by foreign objects, thus affecting normal operation.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] During operation, when testing the asphalt content, the discharge box containing the asphalt mixture to be tested is first placed on the weighing scale 12 inside the combustion chamber. The switch door 11 is closed, and the weighing scale 12 monitors the initial mass of the discharge box and the sample in real time. After the combustion process begins, the control system periodically starts the cylinder 221 and the drive motor 211 according to a preset program. Specifically, when the cylinder 221 starts, its drive end pushes the connecting plate 222 upward, which in turn drives the entire support frame 215 to rise through the rotating shaft 213 connected to it. During the rising process of the support frame 215, its lower part is equipped with... The limiting component 23 interacts with the feeding box. Under its own weight, the feeding box slides down the outward inclined surface of the upper part of the two limiting baffles 231, forcing the two limiting baffles 231 to briefly expand outward against the elastic force of the limiting spring 233 until the feeding box is completely placed on the bottom upper surface of the support frame 215. Then, under the action and reaction force of the limiting spring 233, the two limiting baffles 231 clamp inward, thereby flexibly clamping and limiting the feeding box from both sides, so that it is steadily lifted together with the support frame 215 until the feeding box is completely separated from the weighing scale 12 below. Subsequently, the servo drive motor 211 starts and transmits power to the drive block 214, which is fixedly connected to the rotating shaft 213, through the synchronous belt and synchronous pulley. Since the drive block 214 is slidably locked in the middle of the synchronous pulley, the power can be transmitted to the rotating shaft 213 to make it rotate, and drive the support frame 215 and the clamped discharge box to rotate slowly together. The rotation changes the spatial position of the material, exposing the material that was originally located at the bottom and had difficulty contacting oxygen to an oxygen-rich environment, enhancing the turbulence of the airflow in the combustion chamber, promoting the mixing of air and combustibles, thereby significantly accelerating the combustion process and ensuring that the asphalt is fully and evenly burned. After the rotation continues for a preset time, the drive motor 211 stops working, and then the cylinder 221 reverses its action, driving the support frame 215 to descend smoothly and placing the discharge box back on the weighing scale 12. The weighing scale 12 measures the current mass and records the data. After a period of combustion (set by the operator), the drive motor 211 and cylinder 221 start again, and the cycle repeats until the asphalt is completely burned.
