Description

Technical Field

[0001] The present invention relates to the field of environmentally friendly asphalt mixing production equipment, and in particular to a fully mobile hydraulic asphalt mixing station. Background Art

[0002] An asphalt mixing plant, also known as an asphalt concrete mixing plant, is a complete set of equipment used for the mass production of asphalt concrete. It can produce asphalt mixtures, modified asphalt mixtures, and colored asphalt mixtures. It is essential equipment for the construction of expressways, graded highways, municipal roads, airports, and ports. An asphalt mixing plant primarily consists of a batching system, drying system, combustion system, hot material elevator, vibrating screen, hot material storage silo, weighing and mixing system, asphalt supply system, powder supply system, dust removal system, finished product silo, and control system.

[0003] Currently, two methods are commonly used to prepare asphalt mixtures. One involves batching the mixture at a fixed asphalt mixing plant at the material yard, and then transporting the prepared asphalt to the construction site by transport trucks. This method does not require the asphalt mixing plant to be moved, but does require vehicles to transport the prepared mixture to the construction site, increasing transportation costs and making it relatively inefficient. The other method involves transporting each component of the asphalt mixing plant to the construction site separately and then assembling it there. This method requires each component to be transported to the construction site for assembly and then disassembled and transported back after construction is completed, increasing workload and labor intensity, and reducing efficiency during the preparation phase. Summary of the Invention

[0004] An object of the present invention is to provide a fully mobile hydraulic asphalt mixing plant that solves at least any aspect of the above-mentioned technical problems.

[0005] A further object of the present invention is to avoid low construction efficiency and increase in workload and work intensity.

[0006] Another further object of the present invention is to improve construction efficiency and reduce the assembly and disassembly of the mixing station.

[0007] In particular, the present invention provides a fully mobile hydraulic asphalt mixing plant, comprising a four-bucket reclaimer, wherein the four-bucket reclaimer is used for supplying raw materials; A drying unit, which is used to dry the raw materials supplied by the mobile four-bucket reclaimer; A dust removal control unit is provided on one side of the drying unit to assist the drying unit in removing dust; An asphalt tanker unit is connected to the discharge end of the drying unit and is used for supplying asphalt.

[0008] Furthermore, the drying unit includes a trailer assembly, and a drum and a stone bucket are provided on the upper part of the trailer assembly. One end of the stone bucket is connected to the discharge end of the drum, and a main body is provided on one side of the stone bucket. The main body has a stirring cylinder, and the other end of the stone bucket is connected to the upper part of the stirring cylinder, and a burner is provided on the side close to the stirring cylinder.

[0009] Furthermore, hydraulic supports for the stone hoist, hydraulic support leg assemblies and main building hydraulic cylinders are provided on both sides of the trailer assembly, and the hydraulic supports for the stone hoist, hydraulic support leg assemblies and main building hydraulic cylinders are respectively provided corresponding to the stone hoist, the main building and the frame.

[0010] Furthermore, the asphalt tanker unit includes a tanker assembly, a directly heated asphalt tank is provided on the upper portion of the tanker assembly, and an asphalt bagging mechanism is provided on one side of the directly heated asphalt tank.

[0011] Furthermore, one end of the tank truck assembly is provided with a vehicle-mounted fuel tank, and the vehicle-mounted fuel tank is installed in the fuel tank bracket. The other end of the tank truck assembly is provided with a fuel tank transport bracket and a hook.

[0012] Furthermore, a first hanging ladder is provided on one side of the asphalt bag removing mechanism.

[0013] Furthermore, the dust removal control unit includes a transport frame, a power distribution room and a bag dust collector are provided on the upper part of the transport frame, a gravity dust removal assembly and a cold air valve are provided between the power distribution room and the dust collector, the cold air valve is installed on the upper part of the gravity dust removal assembly, and the discharge port of the gravity dust removal assembly is provided with a pneumatic plug-in valve.

[0014] Furthermore, an outer exhaust spiral mechanism is provided at the lower portion of the bag-type dust collector, and a middle portion of the outer exhaust spiral mechanism is connected to the outer side of the bag-type dust collector via an oblique support member.

[0015] Furthermore, a pulse control box, a horizontal air storage tank and an air compressor are provided between the power distribution room and the dust collector. The pulse control box is located at the lower part of the bag dust collector, and the horizontal air storage tank and the air compressor are fixedly arranged close to the pulse control box in sequence.

[0016] Furthermore, a recovery spiral and a dragon chute are connected below the gravity dust removal component.

[0017] Technical effects and advantages of the present invention: The present invention improves transfer efficiency by transporting each unit separately, and the unit modules do not need to be disassembled for transportation. The transfer of traditional asphalt mixing plants requires the completion of equipment disassembly, separate transportation, on-site assembly and commissioning, etc., which takes about 72 hours or more. However, the present invention can complete the assembly on-site within 4 hours. At the same time, the bag dust collector adopts a variable frequency air compressor to automatically adjust the pulse frequency according to the dust concentration; the asphalt loss rate is small: the direct-heated asphalt tank is equipped with a double-helix bag-removing mechanism to realize the automatic disassembly of the asphalt packaging.

[0018] The present invention integrates raw material supply, drying, asphalt supply, and dust removal and recovery into an independent trailer chassis. During transportation, it is only necessary to release the quick-install interfaces between modules without disassembling internal components, making assembly convenient. At the same time, the hydraulic circuits of each module are independently controlled, and "plug and play" is achieved through quick-change connectors, which reduces debugging time compared to traditional centralized hydraulic systems.

The filter bags are made of PTFE film, and the filtration area of ​​each chamber is 120m². When in use, the high-temperature flue gas first undergoes primary dust removal, and the gravity dust removal component 404 is used. Large particles of dust fall into the recovery spiral 425 under the action of centrifugal force. When the flue gas temperature is greater than 160°C, the cold air valve 405 is opened to 50% opening to cool the flue gas to below 140°C to protect the filter bags.
