The utility model relates to the field of chemical detection equipment, in particular to a temperature-control acid-driving device which comprises a shell and a purification bin connected to the outer side of the shell, a partition plate is connected to the interior of the purification bin, a
threaded rod is rotatably connected between the partition plate and the inner bottom of the shell, a
pinion is fixedly arranged on the outer side of the lower end of the
threaded rod in a sleeving mode, and the lower end of the
pinion is fixedly connected with a motor. The outer side of the
threaded rod is sleeved with an inner threaded sleeve in a threaded mode, the upper end of the inner threaded sleeve is fixedly connected with a lifting connecting rod, and the upper end of the lifting connecting rod is fixedly connected with a containing frame. Through the use of the threaded rod, the
pinion, the inner threaded sleeve, the lifting connecting rod, the placement frame, the motor frame, the driving motor and the bull gear, the
digestion bottle can be conveniently taken out from the interior of the shell, and the convenience of taking out the
digestion bottle is improved; through cooperative use of the bearing seat, the rotating shaft, the worm gear, the U-shaped support, the worm and the
rotating disc, the position between the upper cover and the shell can be adjusted conveniently, the shell and the upper cover are not separated, and the convenience of opening and closing of the upper cover is improved.
