[0002] The medium and low temperature asphalt removal and extraction device is a device specifically used for extracting asphalt and removing impurities. The main purpose of the device is to remove impurities, heavy components and unnecessary components in asphalt through a specific extraction process, so as to improve the purity and quality of asphalt.

[0003] For the existing medium and low temperature asphalt removal and extraction device, asphalt removal and extraction operations are usually carried out through multiple devices such as stirring and mixing, evaporation in an evaporator, etc. When the material inside the mixing tank is introduced into the evaporator for evaporation, since the materials are all gathered in the same evaporator and usually no stirring device is provided inside the evaporator, the evaporation efficiency is low.

[0004] Moreover, impurities still need to be separated from the remaining material after evaporation by the evaporator, and the existing extraction device is not provided with a device that can filter impurities, which is inconvenient to use. Therefore, it is necessary to propose a medium and low temperature asphalt removal and extraction device to solve the above-mentioned problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a medium and low temperature asphalt removal and extraction device, including a base and a mixing tank. A discharge pipe is connected to the lower end of the mixing tank. A plurality of uniformly distributed guide pipes are connected to the outer wall of the discharge pipe. The other end of the guide pipe is connected to an evaporation tank. Electric heating pipes are installed between the inner wall and the outer wall of the evaporation tank.

[0007] A bracket is fixedly connected to the lower end of the discharge pipe. A motor is installed inside the bracket. The output end of the motor penetrates through the bracket and is fixedly connected to a driving gear. A plurality of driven gears are meshed with the outer wall of the driving gear. The lower ends of the plurality of driven gears are fixedly connected with rotating shafts. The other ends of the plurality of rotating shafts respectively penetrate through the evaporation tank and are rotatably connected to the evaporation tank. Stirring plates are fixedly connected to the outer wall of the other end of the rotating shaft.

[0008] A blanking pipe is arranged below the mixing tank. The lower ends of the plurality of evaporation tanks are all connected to the blanking pipe through a drainage pipe.

[0009] A separation barrel is fixedly connected to the upper end of the base. A second motor is installed at the lower end of the separation barrel. The output end of the second motor penetrates through the separation barrel and is fixedly connected to a mounting plate. The upper end of the mounting plate is detachably connected to a filter cartridge by bolts.

[0010] To facilitate gas discharge, as an optimization of the medium and low temperature asphalt removal and extraction device of the present utility model, air outlet pipes are connected to the upper ends of multiple evaporation tanks.

[0011] To facilitate controlling the connection and cut-off states of the discharge pipe and the diversion pipes, as an optimization of the medium and low temperature asphalt removal and extraction device of the present utility model, stop valves are installed on the outer walls of the discharge pipe and multiple diversion pipes.

[0012] To facilitate supporting the mixing tank, as an optimization of the medium and low temperature asphalt removal and extraction device of the present utility model, a support ring is fixedly connected to the outer wall of the mixing tank, and the lower end of the support ring is fixedly connected to the base through a support plate.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] In the present utility model, the stop valve on the outer wall of the discharge pipe is opened, and the mixed materials are diverted through multiple guide pipes and introduced into the interiors of multiple evaporation tanks. The electric heating tubes are turned on to heat and raise the temperature of the evaporation tanks. The motor drives the driving gear to rotate. When the driving gear rotates, it drives multiple driven gears meshing with it to rotate, and further drives the rotating shafts connected to them to rotate, so as to drive the stirring plates to stir the materials inside the evaporation tanks, making the heating more uniform, enabling the solvents inside the materials to evaporate and be discharged through the air outlet pipes, improving the evaporation efficiency;
