Description

Technical Field

[0001] The utility model relates to the technical field of emulsified asphalt production, in particular to an anti-corrosion emulsified asphalt production device. Background Art

[0002] Anti-corrosion emulsified asphalt is a modified asphalt that is based on traditional emulsified asphalt and has improved durability and anti-corrosion performance by adding preservatives. This material is widely used in roads, bridges and other engineering projects that need to be exposed to harsh environments for a long time.

[0003] In the production of emulsified asphalt, generally, steps such as asphalt preparation, soap solution preparation, asphalt emulsification, emulsion storage, and preservative addition are involved. In actual production, when preparing the soap solution, there is a problem of difficulty in pumping out the emulsifier due to the different types of soap solutions and ambient temperatures. Currently, manual operations are mostly used, which is time-consuming and labor-intensive, and also seriously affects production efficiency. Moreover, after the production of emulsified asphalt of different specifications is completed, the mixing tank needs to be flushed. The existing device does not clean the tank wall thoroughly, and asphalt sticks to the wall, which seriously affects the quality of the next batch of asphalt. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the purpose of the utility model is to provide an anti-corrosion emulsified asphalt production device. Through the arrangement of a cooling coil and a preheater, the cooling water after heat exchange is introduced into the heating coil to preheat the emulsifier, which greatly increases the pumping amount of the emulsifier and improves the production efficiency. Through the coordinated use of a scraper and a spray plate, when flushing the kettle wall, the impurities on it are scraped off by the scraper, which greatly saves the use of flushing water and improves the production quality.

[0005] The utility model is realized by adopting the following technical solutions:

[0006] The anti-corrosion emulsified asphalt production device includes a preheater and an asphalt storage tank. An emulsifier barrel is arranged above the preheater. The emulsifier barrel is connected to a soap liquid preparation tank through an emulsifier filtering and metering tank. The soap liquid preparation tank is connected to a heat exchanger and a cooler through the soap liquid preparation tank. The heat exchanger and the cooler are connected to a deployment storage tank. The asphalt storage tank is connected to the soap liquid preparation tank.

[0007] When the emulsifier barrel is placed in the preheater, a rotating device is provided under the emulsifier barrel, and the preheater can preheat multiple emulsifier barrels at one time.

[0008] The anti-corrosion emulsified asphalt production device also includes a latex metering tank and a hydrochloric acid metering tank. The latex metering tank is connected to the soap solution preparation tank through a pipeline, and the hydrochloric acid metering tank is connected to the soap solution preparation tank through a pipeline.

[0009] A heating coil is arranged inside the preheater, and a diaphragm pump is arranged between the emulsifier barrel and the emulsifier filtering and metering tank.

[0010] The soap liquid preparation tank is provided with a stirring paddle driven by a driving motor, and the heat exchange cooler is provided with a cooling coil.

[0011] The cooling coil is connected with a cooling water inlet pipeline, and the cooling coil is connected with the heating coil through a heating coil inlet pipeline.

[0012] A spray plate is arranged inside the mixing storage tank, a scraper is arranged outside the spray plate, and a cylinder is connected to the scraper.

[0013] The scraper is annular, and its outer side is tangent to the inner wall of the mixing tank. The preservative is gradually added during the production process.

[0014] After production is completed, the mixing tank needs to be cleaned. First, turn on the spray plate to rinse the tank wall, turn on the agitator and cylinder, and the cylinder pushes the scraper to scrape the tank wall. Under the action of the cylinder, the scraper performs reciprocating piston motion.

[0015] The working principle of the utility model is:

[0016] The emulsifier in the emulsifier barrel enters the emulsifier filter metering tank through the diaphragm pump, and the driving motor drives the stirring paddle to start working, and water is added to the soap solution preparation tank in proportion and heated; then the raw materials in the emulsifier filter metering tank, latex metering tank, and hydrochloric acid metering tank are added to the soap solution preparation tank to prepare the soap solution, and then the colloid mill is turned on, and the asphalt and soap solution in the asphalt storage tank enter the colloid mill together for shearing, and then enter the mixing tank after the heat exchanger and cooler. The liquid phase in the cooling coil passes through the heating coil pipe to heat the emulsifier in the emulsifier barrel; after the production is completed, the mixing tank needs to be cleaned, first turn on the spray plate to rinse the tank wall, turn on the stirring paddle and cylinder, and the cylinder pushes the scraper to scrape the tank wall. Under the action of the cylinder, the scraper performs reciprocating piston motion. Among them, when the emulsifier barrel is placed in the preheater, a rotating device is provided under the emulsifier barrel, and the preheater can preheat multiple emulsifier barrels at a time.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] By adopting the utility model of the anti-corrosion emulsified asphalt production device, the cooling water after heat exchange is introduced into the heating coil through the setting of the cooling coil and the preheater, and the emulsifier is preheated, which greatly increases the pumping amount of the emulsifier and improves the production efficiency; through the coordinated use of the scraper and the spray plate, when the kettle wall is flushed, the impurities on it are scraped off by the scraper, which greatly saves the use of flushing water and improves the production quality.
