[0002] Fractional distillation is a method of separating mixtures of different boiling points. No new substances are produced during the process; the original substances are simply separated, which is a physical change. Fractional distillation is a process of heating a mixture and then cooling it to separate relatively pure substances based on the different boiling points of the components. It is commonly used in petrochemicals.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-4The utility model provides a technical solution: a petrochemical atmospheric and vacuum fractionation equipment, including a fractionation equipment body 1, characterized in that: a plurality of evenly distributed support rods 2 are fixedly connected to the bottom of the fractionation equipment body 1, and the bottom end of the support rod 2 is movably connected to an annular block 3 through a bearing, and the front and rear walls of the annular block 3 are movably connected to a roller 6 through a rotating shaft and a bearing. A circular groove is opened at the bottom of the support rod 2, and a circular block 5 is arranged in the circular groove. The bottom of the circular block 5 is fixedly connected with an anti-slip pad 4, and a movable hole is opened at the top of the inner cavity of the circular groove, and a movable tube 8 is arranged in the movable hole. The side walls of the movable tube 8 are fixedly connected to the limiting blocks 9 near the top, and the inner walls of the left and right sides of the movable hole are opened with limiting grooves matching the limiting blocks 9, the bottom of the movable tube 8 is fixedly connected to the top of the circular block 5, a threaded rod 11 is arranged in the movable tube 8, and the inner wall of the movable tube 8 is provided with a thread matching the threaded rod 11, and the top of the threaded rod 11 is movably connected to the top of the inner cavity of the movable hole through a bearing. Then, an empty slot is opened in the support rod 2 near the top of the movable hole, and a transmission mechanism is provided in the empty slot. The transmission mechanism includes a worm gear 12, and the top of the threaded rod 11 passes through the inner ring of the bearing and extends into the empty slot, and passes through the bottom of the worm gear 12 and is movably connected to the top of the inner cavity of the empty slot through the bearing. A worm 10 is engaged with the rear wall of the worm gear 12, and the left and right ends of the worm 10 are movably connected to the inner walls of the left and right sides of the empty slot through bearings respectively. One end of the worm 10 passes through the inner ring of the bearing and extends outside the empty slot and is fixedly connected to a rotating block 7. Through the mutual cooperation between the support rod 2, the annular block 3 and the roller 6, the device can be easily displaced in multiple angles and directions; at the same time, through the mutual cooperation between the transmission mechanism, the threaded rod 11, the limit block 9 and the movable tube 8, the circular block 5 can be displaced in the up and down directions. After the device is moved to the appropriate position, the circular block 5 can be moved downward to drive the anti-slip pad 4 to stick to the ground, thereby achieving a good anti-slip effect and ensuring the stability of the device when placed.

[0020] Working principle: When in use, the mobile device can be pushed directly through the roller 6 to conveniently move the device. After the mobile device reaches the appropriate position, the rotating block 7 is rotated to drive the worm 10 to rotate, the worm 10 drives the worm wheel 12 to rotate, and the worm wheel 12 drives the threaded rod 11 to rotate. At this time, the movable tube 8 cannot rotate under the limiting action of the limit block 9, and then drives the circular block 5 to move downward until the circular block 5 drives the anti-slip pad 4 to move downward and close to the ground. It can not only cooperate with the roller 6 to play a supporting role, but also have a good anti-slip effect.
