Description

Technical Field

[0001] This utility model relates to the field of asphalt mixture heating chamber technology, specifically a new energy asphalt mixture heating chamber. Background Technology

[0002] The asphalt mixture heating chamber is a specialized piece of equipment that combines storage and conveying functions. Its core structure includes a double V-shaped trough inner tank, a screw conveyor, and a heat transfer oil circulation system. The inner tank features a W-shaped design to optimize mixture distribution, and the hydraulically driven screw conveyor ensures precise discharge. The combination of heat-conducting pipes and an insulation layer ensures continuous heating and insulation of the mixture within the range of 145-170℃. The device effectively maintains the mixture's construction temperature at no less than 135-150℃ through a top loading gate and side unloading port, providing stable thermal material support for road repair projects.

[0003] The existing patent, CN219137305U, entitled "An Asphalt Mixture Heating Box," discloses an asphalt mixture heating box. Its key technical features include a hopper that can be installed on a dump truck. Multiple electric heating tubes are installed on the bottom of the hopper to heat the asphalt mixture inside. A combustion chamber for heating the asphalt mixture is located on the hopper and communicates with the inner cavity of the hopper. A burner is located outside the combustion chamber, with its burner head extending into the interior of the combustion chamber. The heat generated by the combustion chamber not only reaches the top of the asphalt inside the hopper but also heats the bottom of the asphalt through the multiple electric heating tubes at the bottom of the hopper, ensuring simultaneous heating of the asphalt inside and out. This prevents the asphalt from scorching, results in rapid heating, significant energy savings, and lighter weight.

[0004] The heat generated by the combustion chamber of the above-mentioned device not only transfers to the top of the asphalt in the silo, but also heats the bottom of the asphalt through multiple electric heating tubes installed at the bottom of the silo, so that the asphalt is heated inside and out at the same time, making the asphalt less likely to scorch and heating it quickly. However, the asphalt is in a static state in the silo, and the part of the asphalt close to the heating source receives more heat and is prone to scorching, while the part far from the heating source is prone to clumping. This cannot well meet people's needs. In view of the above situation, technical innovation is carried out on the basis of the existing asphalt mixture heating silo. Utility Model Content

[0005] The purpose of this utility model is to provide a heating chamber for new energy asphalt mixtures to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heating chamber for new energy asphalt mixture, comprising a silo and a main shaft. A feed inlet is installed above the silo and is welded to the silo. The main shaft is installed inside the silo and is rotatably connected to the silo. An agitator is welded to the periphery of the main shaft, and an arc-shaped scraper is welded to the periphery of the agitator. A motor drives the agitator to rotate inside the silo via the main shaft. The rotation of the agitator agitates the asphalt mixture, facilitating uniform heating of the asphalt mixture.

[0007] Furthermore, a motor is installed at the right end of the silo, and the motor is embedded in the silo. The motor drives multiple sets of high-strength alloy stirring plates to rotate in three dimensions through the main shaft, so that the material layer continuously tumbles up and down and moves radially, thereby eliminating heat conduction dead angles and ensuring heating uniformity.

[0008] Furthermore, a viewing window is installed inside the left end of the silo, and the viewing window is embedded in the silo. Asphalt mixture is added into the silo through the feed port. The viewing window allows for real-time observation of the remaining amount of asphalt mixture inside the silo. The viewing window is made of high-transparency, high-temperature resistant tempered glass.

[0009] Furthermore, a discharge port is welded to the bottom of the silo, and a discharge assembly is installed inside the discharge port. As the arc-shaped scraper rotates, the asphalt mixture will be guided and conveyed to one side of the discharge port.

[0010] Furthermore, the discharge assembly includes a second motor and a spiral auger, with a spiral auger installed at one end of the second motor. The second motor drives the spiral auger to rotate, quantitatively and stably outputting asphalt mixture, precisely controlling the discharge amount, and achieving uniform discharge speed and stable material flow.

[0011] Furthermore, a spiral heating pipe is installed on the inner wall of the silo, and a temperature sensor is installed on one side of the spiral heating pipe. The temperature sensor monitors the temperature of the heat transfer liquid in real time and controls the heater to heat the heat transfer liquid to a suitable temperature, so as to uniformly heat the asphalt mixture inside the silo.

[0012] Furthermore, a heater is installed on one side of the temperature sensor, and a circulation pump is installed on the other side of the heater. The circulation pump drives the heat-conducting liquid in the spiral heating tube to circulate.

[0013] Compared with existing technologies, the advantages of this invention are as follows: Asphalt mixture is injected into the silo through the inlet, and the material level can be monitored in real time through a viewing window. A spiral heating pipe is installed on the inner wall of the silo, which, together with a circulating pump, drives the flow of heat transfer fluid. A temperature sensor and heater work together to maintain a constant temperature, ensuring uniform heating of the material. Motor one drives the main shaft to rotate the agitator, preventing clumping and promoting heat conduction. A synchronously rotating arc-shaped scraper cleans residue from the inner wall and guides it to the outlet. Motor two drives the spiral auger for quantitative output, ensuring stable discharge.

[0014] 1. When the asphalt mixture is stored inside the silo, the first motor drives the agitator plate to rotate inside the silo via the main shaft. The rotating agitator plate turns the asphalt mixture, which facilitates uniform heating of the asphalt mixture and prevents it from clumping. The arc-shaped scraper rotates synchronously with the agitator plate and scrapes off the asphalt mixture adhering to the inner wall of the silo to prevent it from affecting the heating effect. At the same time, as the arc-shaped scraper rotates, the asphalt mixture is guided and conveyed to one side of the discharge port. The second motor drives the spiral auger to rotate, which outputs the asphalt mixture in a quantitative and stable manner, resulting in better discharge effect.

[0015] 2. This utility model adds asphalt mixture into the silo through the feed inlet. The viewing window allows for real-time observation of the remaining asphalt mixture inside the silo. The spiral heating tubes are evenly distributed spirally in the inner wall of the silo. The circulation pump drives the heat-conducting liquid in the spiral heating tubes to circulate. The temperature sensor monitors the temperature of the heat-conducting liquid in real time and controls the heater to heat the heat-conducting liquid to a suitable temperature, so as to evenly heat the asphalt mixture inside the silo.

[0020] like Figure 1 and Figure 2As shown, a heating chamber for new energy asphalt mixture includes a silo 1 and a main shaft 4. A feed inlet 2 is installed on the top of the silo 1 and is welded to the silo 1. The main shaft 4 is installed inside the silo 1 and is rotatably connected to the silo 1. An agitator 5 is welded to the periphery of the main shaft 4, and an arc-shaped scraper 6 is welded to the periphery of the agitator 5. A motor 3 is installed at the right end of the silo 1 and is embedded in the silo 1. A discharge port 8 is welded to the bottom of the silo 1, and a discharge assembly 9 is installed inside the discharge port 8. The discharge assembly 9 includes a motor 901 and a spiral auger 902, and a spiral auger 902 is installed at one end of the motor 901. During the storage of the asphalt mixture in the silo 1, the motor 3 drives multiple sets of high-strength alloy agitators 5 to rotate in three dimensions through the main shaft 4, causing the material layer to continuously tumble and radially displace, thereby eliminating heat conduction dead zones and ensuring heating uniformity. At the same time, its special surface coating can reduce material adhesion. The arc-shaped scraper 6, rigidly connected to the agitator plate 5, adheres to the cylinder wall during rotation, thoroughly removing adhering material. The spiral angle of the scraper is calculated to move the material towards the discharge port 8, forming a continuous conveying flow. The motor 901 configured at the discharge port 8 drives the spiral auger 902 with stepless speed regulation output, precisely controlling the discharge amount and achieving uniform discharge speed and stable material flow.

[0021] like Figure 1 and Figure 3 As shown, a viewing window 7 is installed inside the left end of the silo 1, and the viewing window 7 is embedded in the silo 1. A spiral heating tube 10 is installed on the inner wall of the silo 1, and a temperature sensor 11 is installed on one side of the spiral heating tube 10. A heater 12 is installed on one side of the temperature sensor 11, and a circulation pump 13 is installed on one side of the heater 12. The asphalt mixture is transported into the silo 1 through the feed inlet 2. The side wall of the silo 1 is provided with a high-transparency viewing window 7, which is made of high-temperature resistant tempered glass. The operator can intuitively monitor the real-time balance and distribution of the asphalt mixture inside. The spiral heating tubes 10 are embedded in the inner wall of the silo 1 in a spiral distribution. Their three-dimensional arrangement ensures that the heat radiation coverage is without dead angles. Combined with the forced circulation system of the heat-conducting medium driven by the circulation pump 13, the heat can penetrate the material layer to achieve deep and uniform heating. Temperature sensor 11 and intelligent temperature control module form a closed-loop control system. By adjusting the power output of heater 12, the temperature of heat transfer fluid is controlled. This constant temperature heating mode can prevent local overheating and aging of asphalt mixture and avoid caking caused by low temperature, significantly improving the thermal stability and construction performance of the material.

[0022] Working Principle: When using this new energy asphalt mixture heating silo, the asphalt mixture is first automatically conveyed to the silo 1 through the inlet 2. A viewing window 7 equipped with high-temperature tempered glass allows for clear observation of material level changes. Spiral heating pipes 10, arranged spirally on the inner wall of the silo 1, work in conjunction with a circulating pump 13 to form a forced circulation system. Temperature sensors 11 and intelligent heaters 12 work together to precisely control the temperature of the heat transfer fluid within the process range, ensuring uniform heating of the material. Motor 3 drives an alloy stirring plate 5 to rotate continuously via a main shaft 4, preventing clumping and promoting heat conduction. A synchronously moving arc-shaped scraper 6 effectively removes residue from the silo wall and guides it to the outlet 8. The spiral angle of the arc-shaped scraper 6 is calculated to move the material towards the outlet 8, forming a continuous conveying flow. At the outlet, motor 901 drives a spiral auger 902 to ensure a stable, uniform, and pulse-free material flow. The entire system achieves efficient and precise asphalt mixture heating and conveying operations.
