The bottom of the purification component 4 is connected with a filter component 5 for filtering out solid impurities. The operating cylinder 42 is blocked by a blocking plate 48. When the calcium oxide needs to be replaced, the screw rod 49 is directly rotated to pull the movable sleeve 47 and the blocking plate 48 outward to release all the calcium oxide 44 in the operating cylinder 42. Even if the internal particles are compacted and semi-hard, it is convenient for the staff to clean out the residual calcium oxide 44 in the operating cylinder 42 after the blocking plate 48 is removed.

Even if any operating cylinder 42 is maintained, the normal operation of other operating cylinders 42 can be guaranteed.

[0025] Embodiment 2 mainly differs from Embodiment 1 in that: an anhydrous ethanol preparation and purification device, the filter assembly 5 comprises a filter box 51 connected to the purification assembly 4, the front of the filter box 51 is hinged with a sealing cover, both sides of the inner wall of the filter box 51 are provided with inclined plates 52, the surface of the inclined plate 52 is polished and smooth, one side of the surface of the inclined plate 52 is fixedly connected with a positioning head 53, the surface of the positioning head 53 is provided with reinforcing ribs, the inner wall of the filter box 51 is movably connected with a filter plate 54, the edge of the filter plate 54 is provided with a metal frame, one side of the surface of the filter plate 54 is fixedly connected with a handle 55, the surface of the handle 55 is provided with anti-slip particles, through the setting of the filter assembly 5, the device can filter out the leaked solid particles in the anhydrous ethanol through the filter plate 54, completely filter out the calcium oxide and its production by-products, and prevent them from entering the final product and affecting the product quality, and during maintenance, only the handle 55 needs to be pulled up to remove the filter plate 54 as a whole and replace it, which is convenient for operation.
