Description

Technical Field

[0001] This utility model relates to the technical field of asphalt processing equipment, specifically a vacuum buffer tank for asphalt production. Background Technology

[0002] In the asphalt processing, vacuum buffer tanks are typically used to buffer the asphalt to stabilize the pressure and flow rate of subsequent processes. In existing technologies, some vacuum buffer tanks introduce asphalt in a layer-by-layer manner. However, because the asphalt has a certain drop height when entering the buffer tank, it is prone to causing severe disturbances under impact, resulting in a large number of air bubbles inside the asphalt. These air bubbles not only affect the uniformity and stability of the asphalt, but may also have an adverse effect on subsequent processing technology and product quality. Therefore, it is urgent to improve this phenomenon. Summary of the Invention

[0003] The technical problem to be solved by this invention is how to effectively reduce the impact generated when asphalt enters the buffer tank.

[0004] The technical solution adopted by this utility model is: a vacuum buffer tank for asphalt production, including a tank body, an inlet located at the top of the tank body, and an outlet located at the bottom of the tank body. The tank body is provided with a buffer chamber, a heating chamber and an insulation chamber from the inside to the outside. A spiral guide plate is provided in the insulation chamber and the spiral guide plate is connected to the inner wall of the buffer chamber.

[0005] The above structure has the following beneficial effects:

[0006] By sequentially arranging a buffer chamber, a heating chamber, and an insulation chamber in the vacuum buffer tank for asphalt production from the inside out, and installing a spiral guide plate inside the buffer chamber, which is connected to the inner wall of the buffer chamber, this structural design achieves orderly flow and stable delivery of asphalt in the pipe. It ensures that the asphalt can flow along the spiral guide plate, preventing asphalt from dripping directly to the bottom of the buffer chamber after entering from the inlet, and effectively reducing the generation of air bubbles.

[0007] Preferably, the spiral guide plate has a baffle at its edge.

[0008] By setting baffles at the edge of the spiral guide plate, it is possible to effectively prevent asphalt from falling off the edge during the flow along the spiral guide plate, thereby avoiding the generation of a large number of air bubbles due to asphalt splashing to the bottom of the buffer chamber and ensuring the quality of subsequent processes.

[0009] Preferably, the spiral guide plate is provided with multiple through holes, which are arranged at intervals.

[0010] By setting multiple through holes on the spiral guide plate, the flow of asphalt between different layers of spiral guide plates can be effectively accelerated. This not only speeds up the flow of asphalt to the next layer of spiral guide plate, but also avoids asphalt accumulation.

[0011] Preferably, the edges of the through hole are chamfered.

[0012] By setting a chamfer at the edge of the through hole, asphalt can be effectively guided to enter the through hole and flow into the next spiral guide plate, reducing flow resistance and improving fluidity.

[0013] Preferably, a guide rod is connected to the bottom edge of the through hole.

[0014] By setting a guide rod at the bottom edge of the through hole, the guide rod can further guide the asphalt to slide down from the upper spiral guide plate along the set guide rod, making the asphalt flow more stable, reducing the impact force caused by the free fall of asphalt, thereby reducing the probability of bubble production and improving the quality of asphalt.

[0015] Preferably, the guide rod has a groove on one side.

[0016] By setting a groove on one side of the guide rod, the groove can effectively guide the asphalt to flow slowly along the surface of the groove, enhance the adhesion between the asphalt and the guide rod, further slow down the falling speed of the asphalt, and reduce the formation of air bubbles during the falling process.

[0017] Preferably, a gap is left between the bottom of the guide rod and the spiral guide plate located at the bottom of the guide rod.

[0018] By setting a gap between the bottom of the guide rod and the spiral guide plate located at the bottom of the guide rod, the bottom of the guide rod can be prevented from blocking the asphalt on the spiral guide plate below it, thus ensuring that the asphalt on the guide rod falls smoothly.

[0019] Preferably, the heating chamber is provided with multiple annular heating tubes arranged sequentially from top to bottom, and a control console is provided on the outer wall of the tank, which is connected to the annular heating tubes.

[0020] By arranging multiple annular heating tubes sequentially from top to bottom within the heating chamber, the annular heating tubes are evenly distributed, and the temperature of the annular heating tubes can be precisely controlled via a control console, ensuring that the asphalt is always within a suitable working temperature range and guaranteeing good fluidity of the asphalt.

[0021] Preferably, the insulation cavity is provided with insulation material.

[0022] By installing insulation material inside the insulation cavity, the heat loss from the heating cavity can be effectively reduced, the thermal energy utilization efficiency can be improved, energy consumption can be reduced, and the temperature inside the tank can also be kept stable.

[0030] The following will be combined with the appendix Figure 1-5 The technical solution of this utility model is clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Example

[0033] The following description, in conjunction with specific embodiments, provides further details. Figure 1-5 As shown, this embodiment is a vacuum buffer tank for asphalt production, including a tank body 1, an inlet 2 at the top of the tank body 1, and an outlet 3 at the bottom of the tank body 1. The tank body 1 includes a buffer chamber 101, a heating chamber 102, and an insulation chamber 103. A spiral guide plate 4 is provided in the buffer chamber 101. The spiral guide plate 4 is spirally connected to the inner wall of the buffer chamber 101 by welding. In order to prevent asphalt from falling off the edge of the spiral guide plate 4 when flowing along it, thereby causing a large number of air bubbles in the asphalt, a baffle is provided at the edge of the spiral guide plate 4. The baffle can effectively prevent the large number of air bubbles caused by asphalt falling off. Multiple through holes 401 are provided on the spiral guide plate 4. The through holes 401 are arranged at intervals, and a chamfer 402 is provided at the edge of the through holes 401. The arrangement of the through holes 401 allows the asphalt to flow smoothly along the spiral guide plate 4. When the asphalt flows slowly on the spiral guide plate 4, it is guided to the through hole 401 by the chamfer 402. Some of the asphalt can fall onto the next spiral guide plate 4 along the through hole 401 when it passes through the spiral guide plate 4, effectively increasing the flow speed of the asphalt from the inlet 2 to the outlet 3. In addition, a guide rod 5 is provided at the edge of the through hole 401, and the guide rod 5 is located between the upper and lower spiral guide plates 4. There is a distance between the bottom of the guide rod 5 and the spiral guide plate 4 located at the bottom of the guide rod 5. One side of the guide rod 5 is a groove with a right angle. When the asphalt passes through the through hole 401 and hits the guide rod 5, the asphalt will flow slowly along the guide rod 5 until it drips onto the next spiral guide plate 4. The setting of the guide rod 5 can effectively reduce the probability of air bubbles being generated when the asphalt falls directly from the through hole 401 onto the next spiral guide plate 4.

[0034] Multiple annular heating tubes 6 are arranged sequentially from top to bottom inside the heating chamber 102. A control console 7 is also installed on the outer wall of the tank body 1. The control console 7 is electrically connected to the annular heating tubes 6, and the heating and cooling of the annular heating tubes 6 are achieved by a switch installed in the control console 7, thereby maintaining the temperature inside the buffer chamber 101. In addition, to prevent excessive heat loss, an insulation chamber is provided outside the heating chamber 102. The insulation chamber is filled with high-efficiency insulation material, which is rock wool, to minimize the amount of heat loss from the heating chamber 102.

[0035] Working principle:

[0036] In use, asphalt enters the buffer chamber 101 through the inlet 2 located at the top of the tank 1. The buffer chamber 101 is equipped with a spiral guide plate 4, which is welded to the inner wall of the buffer chamber 101 and has baffles at its edges. The asphalt flows along the spiral guide plate 4. When it flows to the position where there is a through hole 401, the asphalt slowly flows to the next layer of guide plate under the guidance of the chamfer 402. This process is repeated until the asphalt drips from the last layer of spiral guide plate 4 along the guide rod 5 to the bottom of the buffer chamber 101, so that the asphalt is discharged from the outlet 3.
