Description

Technical Field

[0001] The utility model belongs to the technical field of asphalt emulsification, and in particular relates to a high-efficiency filtering device for emulsified asphalt. Background Art

[0002] In municipal road construction, emulsified asphalt is safer and more environmentally friendly than hot asphalt. It avoids high-temperature paving operations by construction workers and the emission of harmful substances in asphalt. Emulsified asphalt is easy to construct at room temperature and easy to spray.

[0003] However, when the emulsification effect of emulsified asphalt is not good, it is necessary to filter the incompletely emulsified asphalt particles in the emulsified asphalt. During the filtration process, the filter becomes clogged and needs to be replaced. However, the existing filter is fixed in the cylinder by bolts. During the filtration process, the contact area between the incompletely emulsified asphalt and the filter is relatively fixed, which makes the actual use area of ​​the filter smaller. The part of the filter that contacts the asphalt has a large micropore load due to long-term use, which is easy to cause blockage.

[0004] Therefore, a high-efficiency filtering device for emulsified asphalt is designed to solve the above problems. Utility Model Content

The utility model provides an emulsified asphalt high-efficiency filtering device, which connects the emulsified asphalt with the feed pipe through a pipeline, so that the emulsified asphalt is passed into the interior of the filter box along the feed pipe, and the emulsified asphalt flowing out of the two groups of feed pipes drips on the throwing plate, and at the same time, the stepper motor inside the dust cover is started, and its motor shaft drives the throwing plate at the lower end of the feed pipe to rotate rapidly through the hollow shaft. The emulsified asphalt is thrown to the interior of the filter box along its landslide surface under the action of inertia, and then evenly thrown on the cylindrical filter bag, thereby increasing the use area of ​​the cylindrical filter bag and improving the filtering effect; when replacing the cylindrical filter bag, it is only necessary to pull out the top cover plate and disassemble the inner bolts of the cylindrical filter bag, which is convenient for replacement.

[0006] During filtering, the hollow shaft can drive the outer connecting frame and pleated filter cartridge to rotate. The pleated filter cartridge sticks to the surface of the cylindrical filter bag and rotates, so that the unemulsified asphalt particles are fully adhered to the micropores of the cylindrical filter bag, thereby enhancing the filtering effect. On the other hand, after feeding, the electric telescopic rod at the bottom can be started, and its output end pushes the push rod, which pushes the metal brush seat at the bottom to move downward and fit against the inner wall of the discharge port of the filter box. Under the rotation, the asphalt deposited at the discharge port of the filter box is cleaned to prevent blockage.
