Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0024] See also Figure 1-Figure 3 As shown, the utility model provides a novel asphalt filter, including a filter tank 1 with a cylindrical shape, a support structure 4 is arranged on the bottom side of the filter tank 1, and the support structure 4 includes a ring 401 fixedly arranged on the outside of the filter tank 1, four vertical poles 402 are fixedly connected to the lower side of the ring 401, and the lower ends of the four vertical poles 402 are fixedly connected to each other through a base 403.

The internal liquid flow direction of the feed pipe 2 is perpendicular to the radial direction of the filter tank 1. A first flange 201 is provided at one end of the feed pipe 2 facing the outside of the filter tank 1. Through the above-mentioned specific structural design, it can be realized that when the debris and the mixture enter the filter tank 1, the movement is changed from linear high-speed movement to rotational movement, so that the heavy debris entering the filter tank 1 moves in a circular motion along the inner edge of the filter tank 1 due to inertia and sinks to the outlet at the lower hopper 102. The light SBS, light debris and asphalt are sucked out from the extraction pipe 3 at the middle position. The upper end of the filter tank 1 is provided with an extraction pipe 3, and the lower end of the extraction pipe 3 extends to the lower part of the filter tank 1. A heating component 5 is provided on the outer side of the lower part of the filter tank 1.

[0026] The interior of the filter tank 1 is hollow and the upper end is open. The upper end opening of the filter tank 1 is connected to the tank cover 101 by bolts. The extraction pipe 3 is fixedly arranged on the tank cover 101, and the upper end of the extraction pipe 3 is provided with a second flange 301. An isolation net 6 is arranged outside the extraction pipe 3 located inside the filter tank 1. The isolation net 6 includes a plurality of isolation rods evenly distributed around the axis of the extraction pipe 3. Through the above-mentioned specific structural design, specifically, the upper end of the isolation net 6 is fixedly arranged on the tank cover 101. Therefore, when the tank cover 101 is disassembled, the isolation net 6 can be taken out from the filter tank 1, thereby achieving the cleaning of the isolation net 6.

[0027] A lower hopper 102 is provided at the lower end of the filter tank 1. The shape of the lower hopper 102 is a cone shape that is wide at the top and narrow at the bottom. The heating component 5 is arranged on the lower hopper 102. The heating component 5 includes a conical heating pipe 504, which is sleeved on the outer side of the lower hopper 102. The upper and lower ends of the conical heating pipe 504 are respectively connected to the first oil guide pipe 502 and the second oil guide pipe 503. An outer heat preservation cover 501 is provided on the outer side of the conical heating pipe 504, and one end of the first oil guide pipe 502 and the second oil guide pipe 503 respectively passes through the outer heat preservation cover 501. Through the above-mentioned specific structural design, mainly for hard objects with high density, the temperature of the filter tank 1 during the production of modified asphalt is 180℃-190℃, the fluidity of the mixture is relatively good, and small debris such as screws, welding rod heads, etc. have no viscosity under the same temperature, and can be heated by the heating component 5.

[0028] Working principle:

[0029] The principle of the rotary separator is utilized to feed the mixture from the feed pipe 2 into the filter tank 1 at high speed using a feed pump. The heavy debris entering the filter tank 1 moves in a circular motion along the inner edge of the filter tank 1 due to inertia and sinks to the outlet at the lower hopper 102. The light SBS, light debris and asphalt are sucked out from the extraction pipe 3 at the middle position. The isolation net 6 arranged on the outside of the extraction pipe 3 can remove light debris such as packaging ropes. After the work is completed, the matrix asphalt in the pipe is used to backwash the filter screen, and the light debris also drops to the lower hopper 102 for discharge.
