Description

Technical Field

[0001] The utility model relates to the technical field of asphalt processing equipment, in particular to coal asphalt processing and softening equipment. Background Art

[0002] Asphalt is mainly divided into two types, coal tar and petroleum tar. Coal tar is the residue after high-temperature coal tar distillation and deep processing to extract benzene, industrial naphthalene, light oil, washing oil, phenol oil, anthracene oil, etc., and finally extract asphalt. Coal tar processing and softening is a key process, the main purpose of which is to gradually transform coal tar from solid to liquid to meet its use requirements in different application fields.

When the asphalt is discharged, the asphalt at the bottom edge of the softening box is difficult to be discharged through the discharge valve, which is easy to cause asphalt retention; in addition, part of the softened asphalt may adhere to and remain on the inner wall of the softening chamber. The above-mentioned device lacks a cleaning mechanism and the softening chamber with a closed structure is not conducive to internal cleaning, and the use effect is not good. Therefore, those skilled in the art provide a coal tar pitch processing and softening device to solve the problems raised in the above background technology. Utility Model Content

[0021] Reference Figure 1 , Figure 2 and Figure 3 The utility model embodiment is a coal tar processing and softening device, which includes a base 1 and a cylinder 2 fixedly installed on the top of the base 1, one end of the cylinder 2 is set to be open and covered with a cylinder cover 3, the cylinder cover 3 is rotatably connected to a side of the cylinder 2 close to the cylinder 2 with a connecting shaft 4, a stirring component is arranged on the outer side of the connecting shaft 4, and the end of the connecting shaft 4 opposite to the cylinder cover 3 is rotatably connected to a scraper 5 slidably connected to the inner wall of the cylinder 2, and a driving component for driving the cylinder cover 3 to move horizontally is arranged on the top of the base 1 and close to the cylinder cover 3;

[0022] After the softened coal tar is loaded into the cylinder 2, the cylinder cover 3 is closed on the opening to achieve the sealing operation of the cylinder 2, which is conducive to stirring the coal tar through the stirring assembly to ensure the uniformity of heating of the coal tar. After the softening work is completed, the moving assembly drives the cylinder cover 3 to separate from the cylinder 2, and synchronously drives the scraper 5 to move toward the opening side of the cylinder 2 through the connecting shaft 4. Under the action of the moving scraper 5, the softened coal tar can be discharged to the outside of the cylinder 2, and the moving scraper 5 can better scrape the inner wall of the cylinder 2 to avoid the coal tar residue on the inner wall of the cylinder 2. The overall structure is simple, the discharge work is convenient and efficient, and the practicability is strong.

[0023] Reference Figure 1 , Figure 2 and Figure 3The driving assembly includes two fixed plates 9 fixedly connected to the top of the base 1, a guide rod 11 fixedly connected between the fixed plates 9, a screw rod 10 rotatably connected between the fixed plates 9 and opposite to the guide rod 11, a second motor 12 fixedly connected to the outside of one of the fixed plates 9, and two support plates 7 fixedly connected to the outside of the cylinder cover 3, one of the support plates 7 is threadedly connected to the screw rod 10, and the other is slidably connected to the guide rod 11, and one end of the screw rod 10 close to the second motor 12 passes through the fixed plate 9 and is fixedly connected to the output shaft of the second motor 12 Next, the second motor 12 drives the screw rod 10 to rotate, and the rotating screw rod 10 realizes the left and right movement operation of the support plate 7, so as to better drive the movement of the cylinder cover 3. When the cylinder cover 3 moves to one side of the cylinder body 2, it drives the scraper 5 and the stirring blade 13 to move to the inside of the cylinder body 2. The cylinder cover 3 fits the opening to close the cylinder body 2, which is convenient for subsequent softening work. When the cylinder cover 3 moves to the side away from the cylinder body 2, it drives the scraper 5 to move inside the cylinder body 2, so that the softened coal tar can be discharged to the outside of the cylinder body 2.

[0024] Reference Figure 1 and Figure 3 The stirring assembly includes a plurality of stirring blades 13 evenly and fixedly connected to the outside of the connecting shaft 4 and a first motor 8 fixedly connected to the outside of the cylinder cover 3. One end of the connecting shaft 4 close to the first motor 8 passes through the cylinder cover 3 and is fixedly connected to the output shaft of the first motor 8. The operation of the first motor 8 drives the connecting shaft 4 to rotate, and the rotation of the connecting shaft 4 can better drive the stirring blades 13 to rotate, so that the mixing effect and heating uniformity of the coal tar can be improved through the stirring blades 13, thereby accelerating the softening speed.

[0025] Reference Figure 1 and Figure 3 A plurality of heaters 15 are evenly embedded on the inner wall of the cylinder 2 , and the heaters 15 can be used to heat and soften the coal tar. The heaters 15 embedded inside the cylinder 2 are conducive to ensuring the smoothness of the inner wall of the cylinder 2 .

[0027] Reference Figure 1 and Figure 3 A plurality of through holes 14 are provided inside the scraper 5. When the scraper 5 moves toward the inside of the cylinder 2, the through holes 14 facilitate the discharge of air between the scraper 5 and the cylinder 2.

[0028] Working principle: When the cylinder cover 3 is closed on the opening of the cylinder 2, the scraper 5 is attached to the inner wall of the cylinder 2, and the coal tar material to be softened is fed into the cylinder 2 through the feed pipe 6. The heater 15 is controlled to operate while the first motor 8 is controlled to operate to drive the connecting shaft 4 to rotate. Under the rotation of the connecting shaft 4, the stirring blade 13 can be better driven to rotate, so that the mixing effect and heating uniformity of the coal tar can be improved through the stirring blade 13, thereby accelerating the softening speed;

[0029] After the softening work is completed, the second motor 12 is controlled to run and drive the screw rod 10 to rotate. Under the action of the rotating screw rod 10, the moving operation of the support plate 7 is realized, so that the cylinder cover 3 can be better driven to move. When the cylinder cover 3 moves to the side away from the cylinder body 2, the scraper 5 is driven to move inside the cylinder body 2, so that the softened coal tar can be discharged to the outside of the cylinder body 2, and the moving scraper 5 can better scrape and brush the inner wall of the cylinder body 2, avoiding the coal tar residue on the inner wall of the cylinder body 2.
