Detailed Description of the Embodiments

[0030] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0031] The embodiment of the present utility model discloses a high-efficiency purification device for modified pitch waste gas.

[0032] Embodiment 1

[0033] The present utility model provides as Figures 1-5The modified asphalt waste gas high-efficiency purification device shown includes a body 1 and a heating chamber 2 arranged inside the body 1, a plurality of electric heating rods 20 are fixedly arranged on the inner side wall of the heating chamber 2, a through hole is opened at the end of the body 1, a ring block 3 is rotatably penetrated in the through hole, support frames 4 are fixedly arranged at both ends of the bottom of the body 1, grooves are opened on both sides of the inner wall of the through hole, a first connecting pipe 5 and a second connecting pipe 6 are respectively fixedly penetrated in the two grooves, and the first connecting pipe 5 and the second connecting pipe 6 are both corrugated pipes, an air outlet pipe 7 is connected between the top of the body 1 and the heating chamber 2, an exhaust fan 8 is fixedly arranged on the outer wall of the body 1, and the air outlet of the exhaust fan 8 is connected to the second connecting pipe 6, and air guide pipes 11 are connected on both sides of the purification tank;

[0034] The outer wall of the annular block 3 is provided with a plurality of purification grooves arranged in a symmetrical manner, a molecular sieve 9 is arranged in the purification groove, the notch cover of the purification groove is provided with a cover plate 10, and an installation sink groove for matching the cover plate 10 is provided at the notch of the purification groove. The cover plate 10 is screwed and fixed to the outer wall of the annular block 3, and guide grooves for matching the molecular sieve 9 are provided on both sides of the inner wall of the purification groove.

[0035] Before purifying the waste gas, the device is moved to the side of the modified asphalt production area, and then a plurality of molecular sieves 9 are placed in turn in a plurality of purification tanks outside the annular block 3, and the position of the molecular sieve 9 is determined by the guide groove, and the cover plate 10 is set on the outside of the molecular sieve 9 to ensure the sealing of the purification tank, and then the exhaust fan 8 is started, so that the airflow with waste gas outside enters the second connecting pipe 6 through the exhaust fan 8, and enters the purification tank through the air guide pipe 11. At this time, the molecular sieve 9 can filter the internal substances of the waste gas, and the filtered gas enters the heating chamber 7 through the air guide pipe 11 and the first connecting pipe 5. The waste gas can be effectively purified by a plurality of electric heating rods 20, and the treated gas can flow outward through the outlet pipe 7;

[0036] When the purification effect of the molecular sieve 9 inside the purification tank on one side is reduced, the annular block 3 can be rotated so that the multiple purification tanks outside the annular block 3 can be switched and used to ensure that the purification work is carried out continuously and stably.

[0037] Example 2

[0038] Embodiment 2 is based on Embodiment 1 in order to enable the purification tank to be stably connected to the first connecting pipe 5 and the second connecting pipe 6. Figure 1 and Figure 4As shown in the figure, a plug-in connection mechanism is provided between the air duct 11 and the first connecting pipe 5 and the second connecting pipe 6. The plug-in connection mechanism includes a collar 12, which is fixedly sleeved on the pipe walls of the first connecting pipe 5 and the second connecting pipe 6. Springs 13 are sleeved on the pipe walls of the first connecting pipe 5 and the second connecting pipe 6, and both ends of the springs 13 are fixedly connected to the inner wall of the collar 12 and the groove respectively. The air duct 11 is inserted into the collar 12, and the circumferential sides of the collar 12 and the air duct 11 are both tapered.

[0039] Since the pipe walls of the collar 12 and the air duct 11 are inclined, when the annular block 3 rotates, the air duct 11 can push the inner wall of the collar 12 through the inclined surface on its outer side, causing the collar 12 to be pushed and squeeze the first connecting pipe 5 and the second connecting pipe 6, and the spring 13 to be compressed. When one side of the air duct 11 moves away from the collar 12, the collar 12 rebounds to its original position. At this time, the air duct 11 on the outer side of the other purification tank starts to contact the outer wall of the collar 12, causing the collar 12 to continue to be squeezed and move horizontally. When the annular block 3 rotates to a fixed position, the collar 12 is sleeved on the outer side of the air duct 11 due to the elastic recovery of the spring 13, ensuring a stable connection between the air duct 11 and the first connecting pipe 5 and the second connecting pipe 6 and facilitating the stable flow of gas.

[0040] Embodiment 3

[0041] On the basis of Embodiment 1, in order to enable the annular block 3 to rotate stably to complete the switching and use between multiple purification tanks, as Figure 2 and Figure 5 shown, a position-changing mechanism is provided between the annular block 3 and the support frame 4. The position-changing mechanism includes a worm gear 14 and a worm 15. A rotating plate 17 is fixedly provided on the inner wall of the annular block 3 through a plurality of connecting rods 16. An operation groove is opened at the upper end of the outer wall of the support frame 4, and a rotating rod 18 is rotatably inserted into the operation groove. The rotating rod 18 is fixedly sleeved with the rotating plate 17. The worm gear 14 is fixedly sleeved with the worm 15, and the worm 15 is rotatably arranged in the operation groove. The worm 15 is arranged in cooperation with the worm gear 14, and a rotating block 19 is fixedly sleeved on the rod wall of the worm 15.

[0042] When it is necessary to switch and use purification tanks at different positions, the rotating block 19 can be rotated, causing the rotating block 19 to drive the worm 15 to rotate. Through the cooperation of the worm 15 and the worm gear 14, the worm gear 14 can drive the rotating rod 18 to rotate, and drive the entire annular block 3 to rotate through the rotating plate 17 and the connecting rods 16, so as to switch the positions between multiple purification tanks and ensure the continuous and stable progress of the waste gas treatment work.

[0043] Only some exemplary embodiments of the present utility model have been described by way of illustration. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
