Description
Technical Field
[0001] This utility model relates to the field of road engineering equipment technology, and in particular to an asphalt mixture heating and insulation silo. Background Technology
[0002] In the field of road construction, asphalt mixtures, as the core material for pavement, directly affect the construction quality and service life of the road surface due to their temperature stability and uniformity. Asphalt mixtures need to maintain good fluidity and cohesion within a specific temperature range. Too low a temperature leads to paving difficulties and insufficient compaction, while too high a temperature easily causes material aging. With the expansion of infrastructure construction such as highways and municipal roads, and the increasing demands for construction efficiency and pavement quality, the storage, insulation, and mixing of asphalt mixtures have become critical control points. Heated and insulated silos, as the connecting equipment between asphalt mixture production and paving, play a vital role in temporary storage, temperature maintenance, and ensuring material uniformity. Their performance directly affects the continuity of construction and the quality of pavement formation, making them indispensable in modern road construction equipment systems.
[0003] The existing process of heating and insulating asphalt mixture silos mainly revolves around storage, heating, mixing, and discharge: the silo is usually divided into several storage areas for storing asphalt mixtures of different proportions or batches; the material inside the silo is continuously heated by a heating device on the silo wall, and the set temperature is monitored and maintained in real time by a temperature sensor; some silos are equipped with a mixing mechanism, which drives the mixing shaft or mixing blades to rotate by a motor to prevent the mixture from segregating due to static conditions; when discharge is required, the discharge valve at the bottom of the silo is opened, and the mixture is discharged under the action of gravity or a screw conveyor to supply equipment such as pavers.
[0004] In existing technologies, when some mixing devices use a single mixing parameter, large-capacity bins may experience uneven material mixing due to insufficient mixing force, resulting in local segregation and agglomeration. This makes it difficult to achieve real-time dynamic adaptation, leading to poor consistency in the quality of asphalt mixtures in different bins, which in turn affects the uniformity of subsequent road construction. To address the above-mentioned problems, a heating and insulation bin for asphalt mixtures is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an asphalt mixture heating and insulation silo, which aims to improve the poor mixing adaptability caused by different silo capacities in some existing devices.

[0007] This utility model has the following beneficial effects: 1. In this utility model, for two storage bins of different sizes in the containing bin, motor 2 drives the stirring rod to rotate precisely through pulley 1, rotating track 2, pulley 2 and connecting plate 1. This can not only adapt to the stirring needs of materials with different capacities, but also ensure that the materials in the two bins are mixed evenly, avoiding local sedimentation or clumping. During discharge, motor 1 drives two sets of spiral discharge pipes to operate synchronously through rotating wheel 1, rotating track 1 and rotating wheel 2, so that the materials in the two bins can be output independently, which significantly improves the discharge efficiency, meets the needs of continuous operation, effectively prevents the material from changing its physical properties due to temperature fluctuations, ensures the consistency of material performance, and improves the operating quality and efficiency of the equipment.
[0008] 2.

When closed, it effectively prevents external dust from entering the two storage compartments of different sizes, avoiding material contamination and ensuring material cleanliness; when opened, it quickly exposes the compartment opening, facilitating the addition of raw materials by operators or feeding equipment, significantly shortening the material preparation time. The overall structure, through the coordinated transmission of multiple components driven by the motor, balances dustproof sealing with convenient material feeding, improving both the quality of material storage and overall operational efficiency.

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.
[0012] Reference Figures 1 to 3 The present invention provides an embodiment of an asphalt mixture heating and insulation silo, comprising a storage silo 1, which is used to store asphalt mixtures of different proportions or batches. A mixing and discharging mechanism 2 is fixedly connected to the outside of the storage silo 1. The mixing and discharging mechanism 2 integrates mixing and discharging functions to ensure that the material in the silo is uniform and can be output efficiently. An opening and closing mechanism 3 is rotatably connected inside the storage silo 1. The opening and closing mechanism 3 is used to realize the automatic opening and closing of the silo opening, taking into account both dust prevention and convenient material feeding. The mixing and feeding mechanism 2 includes a drive assembly 21 for driving, which provides power for the discharge stage and realizes the rotation of the spiral discharge pipe 24. A rotating track 22 is sleeved and connected to the outside of the drive assembly 21. The rotating track 22 is used to connect the rotating wheel 212 and the rotating wheel 23, transmit power and ensure that the two rotate synchronously. The external of the storage bin 1 is rotatably connected to the rotating wheel 23. The rotating wheel 23 receives power through the rotating track 22 and drives the corresponding spiral discharge pipe 24 to rotate. The spiral discharge pipe 24 is fixedly connected inside the rotating wheel 23. The spiral discharge pipe 24 pushes the mixture in the storage bin through the rotation of the spiral blades to achieve quantitative and stable discharge. The two storage bins correspond to spiral pipes of different specifications to adapt to different capacity requirements. Two motors 25 are fixedly connected to the outside of the storage chamber 1. The motors 25 provide power to the stirring mechanisms of the two different storage chambers. The drive ends of the two motors 25 are fixedly connected to pulleys 26. The pulleys 26 transmit the rotational power of the motors 25 to the rotating track 27. The pulleys 26 are rotatably connected to the outside of the storage chamber 1. The top of the inner side of the storage chamber 1 is rotatably connected to pulleys 28. The pulleys 28 receive the power transmitted by the rotating track 27 and transmit it to the connecting plate 29. The rotating track 27 is externally coupled to the pulleys 28 and 26. The rotating track 27 is used to connect the pulleys 26 and 28 to smoothly transmit power. A connecting plate 29 is fixedly connected to the outside of the pulley 28. The connecting plate 29 is used to make the agitator 2010 rotate synchronously with it. Multiple agitators 2010 are fixedly connected to the outside of the connecting plate 29. The agitators 2010 agitate the mixture in the bin by rotating, preventing the aggregate from sinking and the asphalt from floating and causing segregation. The outside of the multiple agitators 2010 is rotatably connected to the inside of the receiving bin 1. The outside of the connecting plate 29 is rotatably connected to the inside of the receiving bin 1. The outside of the spiral discharge pipe 24 is rotatably connected to the bottom of the inside of the receiving bin 1. The outside of the rotating track 22 is rotatably connected to the outside of the receiving bin 1. The drive assembly 21 includes a motor 211, which drives a rotating wheel 212 to rotate. The driving end of the motor 211 is fixedly connected to the rotating wheel 212. The motor 211 is externally fixedly connected to the outside of the receiving chamber 1. The rotating wheel 212 is externally fixedly connected to the outside of the spiral discharge pipe 24. The rotating wheel 212 receives power from the motor 211 and directly drives the spiral discharge pipe 24 connected to it. The rotating wheel 212 is externally rotatably connected to the outside of the receiving chamber 1.
[0013] Reference Figure 1 and Figure 4 The opening and closing mechanism 3 includes a motor 31, which provides power for the rotation of the opening and closing plate 38 and controls the opening and closing angle and speed. The drive end of the motor 31 is fixedly connected to a rotating column 32, which is used to transmit the rotational motion of the motor 31 to the connecting ring 33, thus playing a power transmission role. The outside of the rotating column 32 is fixedly connected to the connecting ring 33, which is used to rotate synchronously with it and drive the fixed plate 34. The outside of the connecting ring 33 is fixedly connected to the fixed plate 34, and the outside of the fixed plate 34 is fixedly connected to the fixed column 35, which is used to extend the lever arm to drive the connecting rod 36 to rotate. A connecting rod 36 is fixedly connected to the outside of the fixed column 35. The connecting rod 36 transmits the rotational motion to the bin opening position. A connecting plate 37 is fixedly connected to the outside of the connecting rod 36. An opening and closing plate 38 is fixedly connected to the outside of the connecting plate 37. The opening and closing plate 38 covers the bin opening. When closed, it prevents dust from entering. When open, it exposes the bin opening for easy material feeding. The opening and closing plate 38 and the connecting plate 37 are rotatably connected to the outside of the receiving bin 1. The bottom of the motor 31 is fixedly connected to the top of the receiving bin 1. A heat transfer oil pump 4 is fixedly connected inside the receiving bin 1. The heat transfer oil pump 4 is used to pump heat transfer oil into the internal interlayer of the receiving bin 1. The heat transfer oil circulation maintains the stable temperature inside the bin and ensures that the asphalt mixture maintains good performance within the set temperature range.
[0014] Working principle: When it is necessary to stir the contents of the receiving chamber 1, which has two storage chambers of different sizes, the operation of motor 25 drives pulley 26, which in turn drives the rotating track 27 and pulley 28, which in turn drives the connecting plate 29, which in turn drives the stirring rod 2010, thus stirring the internal materials. When it is necessary to output the materials from the receiving chamber 1, the operation of motor 211 drives the rotating wheel 212, which in turn drives the rotating track 22 and rotating wheel 23, which in turn drives the spiral discharge pipe 24 connected to the rotating wheel 212, thus achieving the effect of rotating and pushing out the materials from the two chambers of the receiving chamber 1, increasing the discharge rate. At the same time, the heat transfer oil pump 4 can introduce it into the internal jacket of the receiving chamber 1 to ensure temperature stability.
[0015] When it is necessary to cover the container 1, the operation of motor 31 drives the rotation of the rotating column 32, which in turn drives the rotation of the connecting ring 33 and the fixing plate 34, thereby driving the rotation of the fixing column 35 and the connecting rod 36, which in turn drives the rotation of the connecting plate 37 and the opening and closing plate 38, thereby reducing dust entry and facilitating quick material loading.
[0016] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
