Description

Technical Field

[0001] The utility model belongs to the technical field of asphalt emulsification, and in particular relates to an asphalt emulsification device. Background Art

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid and an organic gelling material that is waterproof, moisture-proof and corrosion-resistant. Asphalt is mainly used for paving roads, etc. Asphalt is solid at room temperature, so it needs to be emulsified before use.

[0003] The existing authorized public number is CN201770661U, which discloses an asphalt emulsification device, which consists of a charging port, a conveying pipeline, a conveying pump, a batching pipeline, an emulsifying tank, an emulsifying machine, an output port, a preheating tank, a heating tank, and a heating furnace. Its characteristics are that one end of the conveying pipeline is arranged at the upper part of the heating tank, the other end of the conveying pipeline is arranged at the upper part of the emulsifying tank, and a conveying pump is arranged in the middle of the conveying pipeline; the heating tank is arranged inside the preheating tank, the charging port is arranged at the upper end of the preheating tank, the heating furnace is arranged below the heating tank, the batching pipeline is arranged at the upper end of the emulsifying tank, the emulsifying machine is arranged at the lower part of the emulsifying tank, and the output port is arranged on one side of the lower part of the emulsifying tank. The beneficial effects of the utility model are: the entire operation process is carried out in a closed state, there is no evaporation loss of asphalt, which not only reduces the loss but also protects the environment. However, the above-mentioned asphalt emulsification device does not have an overpressure protection structure. If the asphalt is heated for a long time, if the internal pressure is too high, it may easily cause an explosion and cause unnecessary accidents. At the same time, during the gas emission process after the asphalt is heated, the gas has a heavy odor and easily causes air pollution. Therefore, it is necessary to provide an asphalt emulsification device to solve the above problems. Utility Model Content

[0004] The technical content of the utility model is to provide an asphalt emulsification device.

[0005] In order to solve the above problems, the utility model provides an asphalt emulsification device, including: a heating tank, the outside of the heating tank is fixedly connected with a delivery pipe and a charging port, the right end of the delivery pipe is fixedly connected with an emulsification tank, and the outside of the emulsification tank is fixedly connected with an output pipe; a protective component, the protective component includes a sleeve, and the sleeve is fixedly connected to the top of the heating tank. When in use, asphalt is loaded into the interior of the heating tank from the charging port, and the asphalt becomes liquid after being heated. The liquid asphalt is transported to the interior of the emulsification tank through the delivery pipe under the action of a pump body. During the process, the gas evaporated by the heating of the asphalt can exert a reverse force on the piston. At this time, the return spring contracts the piston to slide upward along the inside of the sleeve. When the air pressure is too high, the return spring continues to contract, and the piston slides to the top of the pressure relief pipe. The gas will be discharged through the pressure relief pipe, thereby avoiding safety accidents caused by excessive pressure and achieving a protective effect. When the gas is discharged from the pressure relief pipe, impurities in the gas can be filtered through the filter plate to avoid direct discharge into the air. The odor in the gas can be adsorbed through the activated carbon layer to avoid direct discharge of the odor to cause air pollution.

When the asphalt inside the heating tank is heated and the air pressure is increased, the piston will slide upward along the inside of the sleeve and the return spring will contract at the same time, thereby achieving dynamic balance of the air pressure inside the heating tank.

[0007] As a further solution of the present invention, a pressure relief pipe is fixedly connected to the outside of the sleeve, and the pressure relief pipe is the same as the inside of the sleeve. The sleeve is connected to the inside of the heating tank, and the pressure relief pipe is located at the top of the piston. When the pressure inside the heating tank is too high and the piston slides to the top of the pressure relief pipe, the gas will be discharged from the inside of the pressure relief pipe to achieve pressure reduction and avoid safety accidents caused by excessive pressure.

[0008] As a further solution of the utility model, a dosing pipe is fixedly connected to the top of the emulsification tank, and an output pipe is fixedly connected to the outside of the emulsification tank.

[0010] As a further solution of the present invention, the top of the slide board is rotatably connected to a threaded rod, the threaded rod is threadably rotatably connected to the inside of the sleeve, the top of the threaded rod is fixedly connected to a turntable, the turntable extends to the outside of the sleeve, and the turntable can drive the threaded rod to rotate by external force, thereby adjusting the downward sliding position of the piston to reach a predetermined pressure relief threshold.

[0011] As a further solution of the utility model, a purification pipe is fixedly connected to the outside of the pressure relief pipe, and an activated carbon layer is fixedly connected to the inside of the purification pipe. The activated carbon layer can purify the odor in the exhaust gas.

[0012] As a further solution of the utility model, two filter plates are fixedly connected to the interior of the purification tube, and the two filter plates are located outside of both sides of the activated carbon layer.

[0013] In summary, the present invention includes at least the following beneficial technical effects:

The liquid asphalt is transported to the interior of the emulsification tank through the delivery pipe under the action of the pump body. During the process, the gas evaporated by the heat of the asphalt can exert a reverse force on the piston. At this time, the return spring contracts the piston and slides upward along the inside of the sleeve. When the air pressure is too high, the return spring continues to contract, and the piston slides to the top of the pressure relief pipe. The gas will be discharged through the pressure relief pipe, thereby avoiding safety accidents caused by excessive pressure and achieving a protective effect.

[0015] Second, the utility model records an asphalt emulsification device. When gas is discharged from the pressure relief pipe, impurities in the gas can be filtered through the filter plate to avoid direct discharge into the air.
