Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices for asphalt processing, and particularly relates to a filtering device for asphalt processing. Background Art

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbon compounds with different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid, in a liquid state, with a black surface, and soluble in carbon disulfide. Asphalt is a waterproof, moisture-proof and anti-corrosion organic cementing material. Asphalt can be mainly divided into three types: coal tar asphalt, petroleum asphalt and natural asphalt. When asphalt is used, a filtering device needs to be used for filtering before it can be used.

[0003] Existing public patent: CN202120206460.5, a filtering device for asphalt processing, is provided with a filtering mechanism. Filter meshes are embedded on both sides of the filtering box body of the filtering mechanism. A first scraper is rotatably connected inside the filtering box body. A second rotating rod is fixedly connected to the first scraper. The second rotating rod penetrates through the side wall of the tank body and is located outside the tank body. The first scraper can be rotated manually to prevent the filter meshes from being blocked.

[0004] However, in this comparison, the filter meshes are directly installed inside the filtering box body, which is inconvenient for disassembly. After the filter meshes are used, they need to be cleaned. In this comparison, the direct installation of the filter meshes inside the filtering box body makes it laborious and time-consuming to disassemble the filter meshes, and thus it is not convenient to clean the filter meshes, which reduces the working efficiency of the filtering device and further reduces the practicability of the filtering device.

[0087] Among them, the adjacent ends of the two sliding rods 7 both extend into the two mounting holes 12 and are slidably connected to the mounting holes 12;

[0088] Among them, the first connecting pipe 2 is internally communicated with the second connecting pipe 17;

[0089] Among them, a rubber gasket is provided on the upper surface of the first fixing ring 18.

[0090] Furthermore, in this solution, a sealing material is provided between the inner cavity 20 and the outer surface of the filter box 1 for sealing the filter box 1;

[0091] Furthermore, in the initial state, the rear side surface of the second sliding block 16 contacts the rear inner wall of the inner cavity 20. At this time, the first fixing ring 18 and the second fixing ring 19 are attached. Asphalt is fed into the filter net 15 through the hopper 3, the first connecting pipe 2, and the second connecting pipe 17. Then, the asphalt is filtered through the filter net 15, and impurities will be left in the filter net 15. The filtered asphalt is discharged from the filter box 1 through the fixed pipe 14. Filtering asphalt through the cylindrical filter net 15 can increase the filtering area compared with the traditional flat-shaped filter net, thereby improving the filtering efficiency of the asphalt by the filtering device and further improving the working efficiency of the filtering device;

[0092] As described above, when the filter net 15 needs to be disassembled, the two mounting blocks 8 need to be pulled in opposite directions, so that the two sliding rods 7 move in opposite directions. During this process, the support spring 9 is stretched. When the two sliding rods 7 move in opposite directions, they will slide out of the two mounting holes 12. At this time, the first sliding block 11 can be pulled forward. When the first sliding block 11 slides forward, it drives the filter net 15 and the first sliding block 11 to move forward. During this process, the second connecting pipe 17 and the first fixing ring 18 slide out of the filter box 1 through the sealing groove 5. Then, the filter net 15, the first sliding block 11, and the second sliding block 16 slide out of the filter box 1, thus completing the disassembly of the filter net 15. The disassembly is convenient, the installation is fast, and the disassembly is labor-saving, thereby improving the cleaning efficiency of the filter net, further improving the filtering efficiency of the device for filtering asphalt, facilitating the cleaning of the filter net 15, and increasing the practicability and flexibility of the filter net 15;

[0093] As described above, the sealing ring 13 can enhance the sealing of the sliding groove 4, thereby improving the sealing effect between the first sliding block 11 and the sliding groove 4, avoiding asphalt leakage, increasing the practicability of the filter box 1, and increasing the use of the device.

[0094] Furthermore, in this solution, the areas of the first fixing ring 18 and the second fixing ring 19 are relatively large. The first fixing ring 18 and the second fixing ring 19 can increase the sealing area between the first connecting pipe 2 and the second connecting pipe 17, and also improve the sealing effect between the first connecting pipe 2 and the second connecting pipe 17, thereby avoiding asphalt leakage and increasing the stability of the filtering device.

[0095] Working principle: When the device is in use, in the initial state, the rear surface of the second sliding block 16 contacts the rear inner wall of the inner cavity 20. At this time, the first fixing ring 18 fits with the second fixing ring 19. Asphalt is fed into the filter screen 15 through the hopper 3, the first connecting pipe 2, and the second connecting pipe 17. Then, the asphalt is filtered through the filter screen 15. Impurities will be left in the filter screen 15, and the filtered asphalt is discharged from the filter box 1 through the fixed pipe 14. Filtering asphalt through the cylindrical filter screen 15 can increase the filtering area compared with the traditional flat filter screen, thereby improving the efficiency of filtering asphalt by the filtering device, and further improving the working efficiency of the filtering device.

[0096] As described above, when the filter screen 15 needs to be disassembled, two mounting blocks 8 need to be pulled in opposite directions, so that the two sliding rods 7 move in opposite directions. In this process, the support spring 9 is stretched. When the two sliding rods 7 move in opposite directions, they will slide out of the two mounting holes 12. At this time, the first sliding block 11 can be pulled forward. When the first sliding block 11 slides forward, it drives the filter screen 15 and the first sliding block 11 to move forward. In this process, the second connecting pipe 17 and the first fixing ring 18 slide out of the filter box 1 through the sealing groove 5. Then, the filter screen 15, the first sliding block 11, and the second sliding block 16 slide out of the filter box 1, thus completing the disassembly of the filter screen 15. The disassembly is convenient, the installation is fast, and the disassembly is labor-saving, thereby improving the cleaning efficiency of the filter screen, further improving the efficiency of filtering asphalt by the device, facilitating the cleaning of the filter screen 15, and increasing the practicability and flexibility of the filter screen 15.
