DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. 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 embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1 , 2As shown, a modified asphalt filtering device includes: a shell 1, a first filter plate 2 and a second filter plate 3. The shell 1 is a cylindrical body which is vertically arranged and has an open bottom end. The shell 1 includes a first side plate 4 and a second side plate 5 which are parallel to each other. One end of the first filter plate 2 is connected to the bottom end of the first side plate 4 and forms an obtuse angle with the first side plate 4. The two ends of the second filter plate 3 are a first end 6 and a second end 7 respectively. The first end 6 is hinged to an end of the first filter plate 2 away from the first side plate 4 so that the second end 7 can switch between a first position connected to the bottom end of the second side plate 5 and a second position away from the bottom end of the second side plate 5. When the second end 7 is in the second position, the second filter plate 3 and the first filter plate 2 have the same extension direction. In actual production, as shown in the figure, the first end 6 is hinged to an end of the first filter plate 2 away from the first side plate 4 through a hinge 8. In actual use, as shown in the figure, Figure 1 As shown in FIG, the second end 7 is located at the first position, at which time the first filter plate 2 and the second filter plate 3 together form a seal on the bottom end of the housing 1. At this time, the modified asphalt material entering the housing 1 can be filtered by the first filter plate 2 and the second filter plate 3 and then discharged out of the housing 1. When the first filter plate 2 and the second filter plate 3 need to be cleaned, as shown in FIG. Figure 2 As shown in the figure, the second end 7 is moved to the second position, and an opening is formed between the second filter plate 2 and the second side plate 5, so that it is convenient for the operator to clean the first filter plate 2 and the second filter plate 3. Compared with the prior art, there is no need to replace the first filter plate 2 and the second filter plate 3, which not only saves costs, but also prevents the phenomenon of affecting production efficiency due to frequent replacement of the filter net.

[0030] Furthermore, if Figure 1 , 2 As shown, it also includes a locking mechanism 9. When the second end 7 of the second filter plate 3 is located at the first position, the second filter plate 3 is fixed to the second side plate 5 through the locking mechanism 9. Specifically, Figure 1 , 2 As shown, the locking mechanism 9 includes a first electromagnet 10 and a second electromagnet 11. The first electromagnet 10 is fixedly connected to the second filter plate 3, and the second electromagnet 11 is fixedly connected to the housing 1. When the second end 7 of the second filter plate 3 is located at the first position, the first electromagnet 10 can be attracted to the second electromagnet 11. It should be noted that the locking mechanism 9 is not limited to the method of attracting and locking the first electromagnet 10 and the second electromagnet 11, and any other technical solution that can achieve the purpose of the invention can also be used.

[0031] Preferably, Figure 1 , 2As shown, the second side plate 5 further includes a door plate 12, a notch 13 having a shape matching that of the door plate 12 is provided at the bottom end of the second side plate 5, the door plate 12 is fixedly connected to the second end 7, when the second filter plate 3 is in the first position, the door plate 12 covers the notch 13, the first electromagnet 10 is fixedly connected to the door plate 12, and the second electromagnet 11 is fixedly connected to the second side plate 5. The door plate 12 can be fixedly connected to the second end 7 by welding, but is not limited thereto, and any other technical solution that can achieve the purpose of the invention can also be adopted.

[0032] As an implementation method, Figure 1 , 2 As shown, the first side plate 4 also includes a first driving device 14 and a scraper 15. The first driving device 14 is fixedly connected to the first side plate 4 and is in driving connection with the scraper 15. When the second filter plate 3 is located at the second position, the first driving device 14 drives the scraper 15 to perform linear reciprocating motion on the surfaces of the first filter plate 2 and the second filter plate 3. In this way, the surfaces of the first filter plate 2 and the second filter plate 3 can be cleaned by the scraper 15.

[0033] Furthermore, if Figure 1 , 2 As shown, it also includes a slide 16, which is fixedly connected to the surface of the first filter plate 2, and the scraper 15 is slidably connected to the slide 16, and is used to move along the slide 16 under the drive of the first drive device 14. In this way, the stability of the scraper 15 and the straightness of the running track can be ensured. In the specific production, the slide 16 can be fixed to the surface of the first filter plate 2 by screws to facilitate disassembly and installation. The way in which the scraper 15 is slidably connected to the slide 16 can adopt any feasible way. In actual production, the number of slides 16 is two and corresponds to the two ends of the scraper 15 respectively.

[0034] As an implementation method, Figure 1 , 2 As shown, it also includes a second driving device (not shown) and a main shaft 17, the main shaft 17 is located inside the housing 1, and both ends are rotatably connected to the inner wall of the housing 1, and a stirring blade 18 is arranged on the surface of the main shaft 17, and the second driving device is connected to the main shaft 17 to drive the main shaft 17 to drive the stirring blade 18 to rotate. Such a technical solution can be used to stir the modified asphalt material entering the housing 1 through the stirring blade 18. In actual production, the stirring blade 18 is a spiral blade.

[0035] As an implementation method, Figure 1 , 2As shown, it also includes a material level sensor 19 and an alarm 20. The material level sensor 19 is arranged in the housing 1 and is electrically connected to the alarm 20. The material level sensor 19 collects the height information of the asphalt entering the housing 1 in real time and sends the information to the alarm 20. The alarm 20 sends an alarm signal according to the received asphalt height information in the housing 1. In actual use, when the first filter plate 2 and the second filter plate 3 are blocked, the height of the modified asphalt material in the housing 1 will increase. At this time, the alarm 20 can alarm according to the height information of the modified asphalt material entering the housing 1 collected in real time by the material level sensor 19, thereby prompting the operator to clean the first filter plate 2 and the second filter plate 3 in time.

[0036] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
