Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of asphalt melting equipment, and in particular to a solid asphalt melting turbulence device. Background Technology
[0002] Asphalt is a dark brown, complex mixture composed of hydrocarbons of varying molecular weights and their non-metallic derivatives. It is a type of high-viscosity organic liquid, mostly existing in liquid or semi-solid petroleum form, with a black surface, and is soluble in carbon disulfide and carbon tetrachloride. Asphalt is mainly used in industries such as coatings, plastics, and rubber, as well as in road paving. Asphalt melting equipment is required during the asphalt production process.
[0003] Currently, melting equipment typically includes a melting tank into which workers pour solid asphalt and heat it to transform it into a fluid, liquid asphalt. For example, one existing asphalt melting heating pool has solid asphalt placed on one side, with heating elements at the bottom to melt it. However, a drawback exists: because the heating elements are only located at the bottom of the melting heating pool, the uppermost layer of solid asphalt is far from the heating elements, resulting in a slow melting rate. Therefore, if only heating elements are used to heat the solid asphalt, it takes a long time for the uppermost layer of solid asphalt in the melting pool to reach a molten state, which not only reduces the melting efficiency of solid asphalt but also increases the production cost of asphalt. Utility Model Content
[0004] In order to improve the melting speed of solid asphalt and reduce the production cost of asphalt, this utility model provides a solid asphalt melting turbulence device.
[0005] This utility model provides a device for turbulent flow in the melting of solid asphalt, which adopts the following technical solution:
[0006] A solid asphalt melting and turbulence device includes a spraying mechanism and a control system. The spraying mechanism includes a return oil pipe and an injector. One end of the return oil pipe is connected to the high-temperature zone of the asphalt melting pool via an asphalt pump, and the other end is connected to the injector. The injector is located in the low-temperature zone of the asphalt melting pool. Asphalt in the high-temperature zone of the asphalt melting pool can enter the low-temperature zone of the asphalt melting pool through the spraying mechanism. The control system includes a temperature sensor and a controller. The temperature sensor is installed on the outside of the injector and is used to monitor the temperature of the solid asphalt in the low-temperature zone of the asphalt melting pool.
[0007] Furthermore, the injection mechanism is equipped with a one-way valve, which is located at the connection between the return oil pipe and the asphalt pump.
[0008] Furthermore, the return oil pipeline includes an output pipe and multiple injection pipes. The output pipe is fixedly connected to the asphalt pump. One end of each injection pipe is connected to the output pipe, and the other end is connected to the injector. The multiple injectors are located above and / or to the side of the low-temperature zone of the asphalt melting pool.
[0009] Furthermore, the injection pipe also includes a first branch pipe and a second branch pipe. The first branch pipe is fixed to the output pipe and sleeved on the second branch pipe. The second branch pipe can move vertically along the axis of the first branch pipe. The injector is installed on the opposite end of the second branch pipe and the first branch pipe.
[0010] Furthermore, the injection mechanism also includes multiple solenoid valves, each of the injection tubes is connected to a solenoid valve, and the multiple solenoid valves are electrically connected to the temperature sensor.
[0011] Furthermore, the injector includes a body and a nozzle. One end of the body is fixed to the nozzle, and the other end is connected to the injection pipe. The nozzle is provided with injection ports evenly distributed along the axis of the body, and the axis of the injection ports forms a certain angle with the axis of the body.
[0012] Furthermore, the angle between the axis of the injection nozzle and the axis of the main body is 0°-90°.
[0013] Furthermore, the turbulence device also includes a vibration mechanism, which includes a rotating shaft, a turbulence plate, and a motor. One end of the rotating shaft is fixed to the turbulence plate, and the other end is fixed to the motor.

[0014] Furthermore, the flow disturbance device also includes a pressure sensor and a lock-up valve, the lock-up valve being disposed on the return oil pipeline, and the pressure sensor being electrically connected to the lock-up valve.
[0015] Furthermore, the turbulence device also includes a liquid level sensor, which is located in the high-temperature zone of the asphalt melting pool and connected to the return oil pipe. The liquid level sensor is used to monitor the changes in the asphalt liquid level in the high-temperature zone of the asphalt melting pool.
[0016] In summary, this utility model has at least one of the following beneficial technical effects:
[0017] 1. By setting up return oil pipes and injectors, the high-temperature liquid asphalt in the melting pool can be returned to the low-temperature zone of the melting pool. The returned high-temperature liquid asphalt transfers heat to the solid asphalt, thereby improving the melting efficiency of the solid asphalt.
[0018] 2. By setting up multiple sets of temperature sensors, spray pipes and sprayers, the temperature at different locations in the low-temperature zone of the melting pool can be monitored and precisely controlled, allowing liquid high-temperature asphalt to be sprayed to any location in the low-temperature zone of the melting pool, avoiding heating dead zones in solid asphalt.
[0019] 3. By setting up a vibration mechanism, turbulence and stirring can be carried out in the low-temperature zone of the asphalt melting pool, preventing the sprayed high-temperature liquid asphalt from existing only on the surface of the low-temperature zone of the asphalt melting pool, accelerating the contact area between solid asphalt and liquid asphalt, thereby greatly improving the melting efficiency of solid asphalt.

[0030] This utility model discloses a device for disrupting the flow of solid asphalt melting. (See attached diagram.) Figure 1 and Figure 2 The solid asphalt melting and turbulence device includes a spraying mechanism 1 and a control system. The spraying mechanism 1 includes a return oil pipe 11 and an injector 12. One end of the return oil pipe 11 is connected to the high-temperature zone 21 of the asphalt melting pool 2 via an asphalt pump 4, and the other end is connected to the injector 12. The injector 12 is located in the low-temperature zone 22 of the asphalt melting pool 2. The asphalt in the high-temperature zone 21 of the asphalt melting pool 2 can enter the low-temperature zone 22 of the asphalt melting pool 2 through the spraying mechanism 1. The control system includes a temperature sensor 3 and a controller. The temperature sensor 3 is fixedly installed on the outside of the injector 12 and is used to monitor the solid asphalt temperature in the low-temperature zone 22 of the asphalt melting pool 2.
[0031] The asphalt melting pool 2 is divided into a high-temperature zone 21 and a low-temperature zone 22. During the asphalt production and melting process, solid asphalt is heated in the low-temperature zone 22 of the asphalt melting pool 2 and then becomes liquid asphalt before entering the high-temperature zone 21. This invention adds a solid asphalt melting turbulence device between the high-temperature zone 21 and the low-temperature zone 22 of the asphalt melting pool 2, which can accelerate the melting speed of solid asphalt in the asphalt melting pool 2. Specifically, the temperature sensor 3 monitors the temperature of the solid asphalt in the low-temperature zone 22 of the asphalt melting pool 2. When the solid asphalt in the low-temperature zone 22 of the asphalt melting pool 2 is lower than the set temperature, the controller can control the asphalt pump 4 to introduce the liquid asphalt in the high-temperature zone 21 of the asphalt melting pool 2 into the return oil pipe 11. Subsequently, the liquid asphalt in the return oil pipe 11 is discharged into the low-temperature zone 22 of the asphalt melting pool 2 through the ejector 12. By setting up this melting and turbulence device, liquid high-temperature asphalt is output into solid asphalt. The high-temperature liquid asphalt can transfer heat to the solid asphalt, thereby accelerating the melting of the solid asphalt, reducing the melting time of the solid asphalt, promoting the fusion process of solid and liquid asphalt, and accelerating the production efficiency of asphalt.
[0032] Temperature sensor 3 is connected to controller (not shown). The controller automatically adjusts the working state of asphalt pump 4 and the injection parameters of injector 12 based on the data provided by temperature sensor 3, so as to keep the temperature in asphalt melting pool 2 within the optimal melting temperature range.
[0033] It should be noted that the embodiments of this utility model do not limit the types of temperature sensor 3, injector 12 and controller. In a preferred embodiment, the temperature sensor 3 is a non-contact temperature sensor 3 and the injector 12 is a pulse injector.
[0034] In some embodiments, the injection mechanism 1 is provided with a one-way valve 13, which is located at the connection between the return oil pipe 11 and the asphalt pump 4. Figure 1 As shown, in a preferred embodiment of this utility model, by setting a one-way valve 13 between the return oil pipeline 11 and the asphalt pump 4, the backflow of liquid asphalt in the return oil pipeline 11 can be prevented.
[0035] In some embodiments, the return oil pipe 11 includes an output pipe 101 and a plurality of injection pipes 102. The output pipe 101 is fixedly connected to the asphalt pump 4. One end of each injection pipe 102 is connected to the output pipe 101, and the other end is connected to an injector 12. The plurality of injectors 12 are located above and / or to the side of the low temperature zone 22 of the asphalt melting pool 2.
[0036] like Figure 1 , Figure 2As shown in the preferred embodiment of this utility model, to prevent turbulence dead zones or insufficient heating of the asphalt in the low-temperature zone 22 of the asphalt melting pool 2, multiple injection pipes 102 are arranged above and to the sides of the low-temperature zone 22 of the asphalt melting pool 2. Each injection pipe 102 has an injector 12 at the opposite end of its connection to the output pipe 101. By arranging multiple injectors 12 laterally and / or longitudinally in the low-temperature zone 22 of the asphalt melting pool 2, and each injector 12 being equipped with a temperature sensor 3, the temperature sensor 3 is used to monitor the asphalt temperature near the corresponding injector 12. By setting multiple injectors 12, high-temperature liquid asphalt can be sprayed to various positions in the low-temperature zone 22 of the asphalt melting pool 2, thereby accelerating the fusion of solid and liquid asphalt in the asphalt melting pool 2.
[0037] In some embodiments, such as Figure 2 and Figure 3 As shown, the injection pipe 102 also includes a first branch pipe 111 and a second branch pipe 112. The first branch pipe 111 is fixed to the output pipe 101 and sleeved on the second branch pipe. The second branch pipe 112 can move along the axis of the first branch pipe 111. The injector 12 is installed at the opposite end of the sleeved connection between the second branch pipe 112 and the first branch pipe 111. This design allows for adjustment of the distance between the injector 12 above the asphalt melting pool 2 and the asphalt melting pool 2, thereby achieving precise control over the asphalt melting effect. In actual operation, workers can manually or automatically adjust the position of the second branch pipe 112 according to the melting state of the asphalt and production needs, thereby changing the injection distance of the liquid asphalt and allowing the liquid asphalt to be sprayed more evenly onto the solid asphalt, thus achieving the effect of high-temperature liquid asphalt accelerating the solidification of asphalt.
[0038] In some embodiments, the injection mechanism 1 further includes a plurality of solenoid valves 14, each injection pipe 102 is connected to a solenoid valve 14, and the plurality of solenoid valves 14 are electrically connected to a temperature sensor 3.
[0039] like Figure 1 and Figure 2 As shown, the solenoid valve 14 is connected to the injection pipe 102, and each injector 12 is equipped with a corresponding temperature sensor 3. The temperature sensor 3, the solenoid valve 14, and the controller are electrically connected. The temperature sensor 3 can measure the asphalt temperature near the corresponding injector 12, which is used to detect the asphalt melting status in various parts of the asphalt melting pool 2. When the temperature sensor 3 detects that the temperature at a certain location in the asphalt melting pool 2 is low, the controller will control the solenoid valve 14 at the nearest location to open, and liquid asphalt can be sprayed to the corresponding location in the asphalt melting pool 2 through the return oil pipe 11 and the injector 12. By precisely controlling the opening and closing of the solenoid valve 14, as well as the injection pressure and frequency of the injector 12, the controller can achieve precise control of the asphalt melting process, thereby accelerating the melting speed of solid asphalt in the low-temperature zone 22 of the asphalt melting pool 2.
[0040] In some embodiments, the injector 12 includes a body 121 and a nozzle 122. One end of the body 121 is fixedly connected to the injection pipe 102, and the other end is fixedly connected to the nozzle 122. The nozzle 122 is provided with injection ports evenly distributed along the axis of the body 121, and the axis of the injection ports forms a certain angle with the axis of the body 121. The angle between the axis of the injection ports and the axis of the body 121 is 0°-90°.
[0041] By setting multiple injection nozzles, the liquid asphalt is more dispersed during the injection process, ensuring that the injected liquid asphalt can evenly cover the area around the injector 12. This increases the contact area between the liquid and solid asphalt, reduces the residue of unmelted solid asphalt, and thus improves melting efficiency, thereby improving the efficiency and quality of the entire asphalt melting process. Preferably, the nozzle 122 of the injector 12 is designed to be replaceable to adapt to asphalt materials of different viscosities, ensuring the stability and reliability of the injection effect.
[0042] In some embodiments, such as Figure 2 As shown, the turbulence device also includes a vibration mechanism 6, which includes a rotating shaft 61, a turbulence plate 62, and a motor 63. One end of the rotating shaft 61 is fixedly connected to the turbulence plate 62, and the other end is fixedly connected to the motor 63. The rotating shaft 61 is located in the low-temperature zone 22 of the asphalt melting pool 2 and is rotatably connected to the asphalt melting pool 2. The motor 63 is fixedly connected to one end of the rotating shaft 61.
[0043] In this embodiment of the invention, the motor 63 is electrically connected to the controller. The controller receives commands and adjusts the rotational speed of the rotating shaft 61 according to the temperature distribution within the asphalt melting pool 2. When the temperature sensor 3 detects that the temperature of a certain low-temperature zone 22 is lower than other areas, the solenoid valve 14 opens. When liquid asphalt is sprayed from the injector 12, the controller controls the motor 63 to rotate. The baffle 62 then rotates in the low-temperature zone 22 of the asphalt melting pool 2, thereby promoting the mixing of liquid and solid asphalt and further improving the melting efficiency of the solid asphalt. Furthermore, the vibration mechanism 6 ensures that the asphalt in the entire melting pool is heated uniformly, avoiding localized overheating or undercooling. In one embodiment, the baffle 62 uses helical blades. These blades not only accelerate the mixing of liquid and solid asphalt but also move the asphalt from the low-temperature zone 22 to the high-temperature zone 21 of the melting pool.
[0044] In some embodiments, the flow disturbance device further includes a pressure sensor (not shown) and a lock-up valve 8. The lock-up valve 8 is disposed on the return oil pipeline 11, and the pressure sensor is electrically connected to the lock-up valve 8. The pressure sensor is used to monitor the pressure changes in the return oil pipeline 11 in real time. When the pressure exceeds a set safety threshold, the sensor sends a signal to the controller. After receiving the signal, the controller instructs the lock-up valve 8 to close quickly to prevent pipeline rupture or equipment damage caused by excessive pressure, ensuring the safe and stable operation of the entire asphalt melting system and improving the reliability of the equipment and the safety of operation.
[0045] In some embodiments, the turbulence device further includes a liquid level sensor 9, which is located in the high-temperature zone 21 of the asphalt melting pool 2 and connected to the return oil pipe 11. The liquid level sensor 9 is used to monitor the changes in the asphalt liquid level in the high-temperature zone 21 of the asphalt melting pool 2.
[0046] When the asphalt level falls below the preset minimum level, the level sensor 9 sends a signal to the controller. Upon receiving the signal, the controller automatically adjusts the injection volume of the injector 12 to ensure that the asphalt level in the melting pool 2 remains within a safe range. This automated level control mechanism not only improves the efficiency of the asphalt melting process but also reduces the need for manual monitoring and lowers operating costs. Furthermore, the introduction of the level sensor 9 makes the entire asphalt melting system more intelligent, enabling it to respond to changes in the asphalt level in real time, ensuring the continuity and stability of the entire melting process.
[0047] The above are merely preferred embodiments of this application and do not limit the scope of the patent application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the scope of patent protection of this application.
