Device for preparing propionic acid by oxidizing propionaldehyde

The utility model discloses a device for preparing propionic acid through propionaldehyde oxidation, which is characterized in that the lower bottom wall of an outer shell is fixedly connected with an inner shell, the lower bottom wall of the inner shell is fixedly connected with a hydraulic rod, the output end of the hydraulic rod is fixedly connected with a propionic acid oxidation preparation device, and the outer surface of the outer shell is fixedly connected with a servo motor; the outer surface of the outer shell is fixedly connected with a first water pipe, one end of the first water pipe is fixedly connected with a water tank, and the outer surface of the outer shell is fixedly connected with a second water pipe. Through double-layer protection of the inner shell and the outer shell, the influence of external factors on preparation of propionic acid is prevented, and heat loss or entering of external heat is prevented; and the stirring blades are used for stirring water when the propionic acid leaks,
