Fixed heating bin

Abstract

This utility model relates to a fixed heating silo, belonging to the field of asphalt mixture reheating technology. It includes a mounting bracket, inside which a heating silo is fixedly installed. Several double-layer heat-conducting oil baffles are fixedly installed on the inner wall of the heating silo, dividing it into several storage silos of the same size. This fixed heating silo, by setting several double-layer heat-conducting oil baffles inside the heating silo, forms a heat-conducting oil cavity between the baffles and the inclined plate of the heating silo. Heat-conducting oil is transported to the heat-conducting oil cavity through a lower pipe and discharged through an upper pipe, forming a heating cycle. Cold asphalt mixture blocks are placed between the baffles, forming a large-area contact with the hot oil, resulting in more uniform heating of large batches of cold asphalt mixture blocks and improving the heating efficiency of the cold asphalt mixture blocks.

Description

Technical Field

[0001] This utility model relates to the field of asphalt mixture reheating technology, specifically a fixed heating silo. Background Technology

[0002] Asphalt mixture is a composite material made by mixing mineral aggregates and asphalt binders in a certain proportion. It combines the skeletal support of mineral aggregates with the bonding and waterproofing properties of asphalt. Through high-temperature heating and mixing, the asphalt uniformly coats the mineral aggregate particles, forming a road paving material with certain strength, flexibility and durability. It is widely used in highways, urban roads, airport runways and other projects. Its performance can be optimized by adjusting the mineral aggregate gradation, asphalt type and additives to meet the usage requirements under different climatic conditions and traffic loads.

[0003] Asphalt mixture cold blocks need to be reheated before use. Utility model patent CN204112190U discloses a heating device for the discharge gate of a fixed silo in an asphalt pavement maintenance vehicle. The device includes a fixed silo body, a discharge gate, a fan, and an air duct. The fixed silo body has an upper exhaust vent, and the discharge gate is located at the discharge outlet of the fixed silo body. The discharge gate has a double-layered cavity structure, with the cavity being a hot air interlayer. The outer layer of the discharge gate is an insulation layer, and the inner layer has an air inlet. An exhaust vent is located on the insulation layer of the discharge gate. The fan is connected to the upper exhaust vent, and the fan's air outlet is connected to the air duct. The air outlet of the air duct is connected to the air inlet of the discharge gate. This device draws the hot air collected at the top of the silo body, which is ready to be discharged from the silo body, into the hot air jacket of the discharge gate under the action of a fan. This heats the inner wall of the discharge gate. Due to the heat conduction, the waste gas from the silo is used to heat the asphalt mixture at the discharge port, making full use of the heat and saving energy.

[0004] However, common fixed silos have a small heating area in contact with asphalt when reheating cold asphalt mixture blocks, which is not suitable for heating large quantities of cold asphalt mixture blocks. Therefore, fixed heating silos are proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a fixed heating silo, which has advantages such as increasing the heating area of ​​cold asphalt mixture blocks, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fixed heating silo includes a mounting bracket, in which a heating silo is fixedly installed. Several double-layer heat-conducting oil baffles are fixedly installed on the inner side wall of the heating silo, dividing the heating silo into several storage silos of the same size. A large-area heating component is provided inside the heating silo.

[0008] The large-area heating assembly includes a heat-conducting oil cavity formed by a double-layer heat-conducting oil partition and an inclined plate of a storage bin. The upper part of the two double-layer heat-conducting oil partitions is connected by an upper pipe, and the lower part of the two double-layer heat-conducting oil partitions is connected by a lower pipe.

[0009] Furthermore, an upper connector is fixedly installed on one side of the heating chamber, and the upper connector is connected to the upper pipe.

[0010] Furthermore, a lower connector is fixedly installed on one side of the heating chamber, and the lower connector is connected to the lower pipe.

[0011] Furthermore, a thermal oil boiler is fixedly installed at the input end of the lower pipeline, and a circulating pump is fixedly installed at the output end of the thermal oil boiler.

[0012] Furthermore, the output end of the circulating pump is connected to the upper connector, and a high-level tank is fixedly installed on the connecting pipe between the upper connector and the circulating pump.

[0013] Furthermore, a folding plate is placed on the top of the heating chamber, and a discharge chamber door is hinged to the bottom of the heating chamber.

[0014] Furthermore, a hydraulic cylinder is hinged to the bottom of the heating chamber, and the movable end of the hydraulic cylinder is rotatably connected to the discharge chamber door. Support legs are fixedly installed at the bottom of the mounting bracket.

[0015] Compared with the prior art, the present invention provides a fixed heating hopper, which has the following advantages:

[0016] This fixed heating silo incorporates several double-layered heat-conducting oil baffles inside the heating chamber. A heat-conducting oil cavity is formed between the baffles and the inclined plate of the heating chamber. Heat-conducting oil is transported to the cavity through a lower pipe and discharged through an upper pipe, creating a heating cycle. Cold asphalt mixture blocks are placed between these baffles, forming a large contact area with the hot oil. This results in more uniform heating of large quantities of cold asphalt mixture blocks, improving heating efficiency. This design solves the problem of common fixed silos, where the heating area in contact with the asphalt is small when reheating cold asphalt mixture blocks, making them unsuitable for heating large quantities of cold asphalt mixture blocks.
