The saponification reaction in the current preparation process of aluminum tris(ethylphosphonate) is incomplete, resulting in a low conversion rate, mainly due to poor mixing of the reaction raw materials.
The design employs two sets of stirring blades, including fixed and movable stirring blades. By intermittently rotating forward and reverse in a drive device, the height and horizontal position of the movable stirring blades are changed, thereby improving the mixing effect.
This resulted in more uniform material mixing, improving the efficiency and conversion rate of the saponification reaction.

Abstract
Description
Technical Field
[0001] This utility model relates to chemical reaction apparatus, and more particularly to an apparatus for saponification of aluminum triethylphosphonate. Background Technology
[0002] Aluminum tris(ethyl phosphonate) is a highly effective, broad-spectrum, and low-toxicity organophosphorus systemic fungicide. It exhibits bidirectional systemic activity, being absorbed by crop roots and translocated to the above-ground stems and leaves, as well as absorbed by upper leaves and translocated to basal leaves, thus providing both protective and curative effects. Its broad fungicidal spectrum is effective against diseases caused by pathogenic fungi of the genera *Peronospora* and *Phytophthora* within the Algae and Mycota phylum. It is suitable for a wide range of crops, including various fruits, vegetables, and flowering plants.
[0003] Currently, the process adopted by domestic manufacturers is to use phosphorus trichloride, anhydrous ethanol, ammonia, and solid aluminum sulfate as the main raw materials, which are then processed through esterification, saponification, and metathesis reactions.
[0004] The existing saponification process for preparing aluminum tris(ethyl phosphonate) is complex and time-consuming. Due to poor mixing of raw materials in the saponification device, incomplete saponification and low conversion rate are easily caused. Utility Model Content
[0005] To address the shortcomings of existing reaction devices for aluminum tris(ethyl phosphonate) with poor mixing performance, this invention provides an aluminum tris(ethyl phosphonate) saponification reaction device.
[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:
[0007] A saponification apparatus for aluminum tris(ethylphosphonate) includes a vessel body with a reaction chamber inside. The reaction chamber contains a stirring device, which includes a stirring shaft driven by an external drive and two types of stirring blades mounted on the shaft. The first type of stirring blade is a fixed blade fixed to the stirring shaft, and the second type is a movable blade movably mounted on the stirring shaft. The side wall of the stirring shaft has a spiral groove. The movable blades have limiting posts extending into the spiral grooves. When the drive is in the forward direction, the spiral posts of the movable blades are at the highest end of the spiral grooves; when the drive is in the reverse direction, the spiral posts of the movable blades are at the lowest end of the spiral grooves. This design, by using two sets of fixed and movable stirring blades to stir the material, and by intermittently driving the movable blades in both forward and reverse directions to change their height and horizontal position, achieves better stirring effect and more uniform material mixing compared to purely fixed blades, which is beneficial for the saponification reaction.
[0008] Preferably, the fixed stirring blade includes an annular fixed sleeve, several first stirring rods disposed on the fixed sleeve, and rectangular blades disposed at the outer ends of the first stirring rods. The fixed sleeve is fitted and fixed on the stirring shaft, and several first stirring rods are disposed in an annular array on the fixed sleeve.
[0009] Preferably, the movable stirring blade includes an annular movable sleeve, several stirring rods disposed on the movable sleeve, and L-shaped blades disposed at the outer ends of the second stirring rods. The movable sleeve is fitted onto the stirring shaft and the limiting post is located on the inner wall of the movable sleeve. Several second stirring rods are disposed and distributed in an annular array on the movable sleeve.
[0010] Preferably, the rectangular blade is located at the notch above the L-shaped blade so that the two do not interfere with each other when the L-shaped blade rises.
[0011] Preferably, the second stirring rod passes through the movable sleeve and is fixed to the movable sleeve, and the second stirring rod extends beyond the inner wall of the movable sleeve to form a limiting post that extends into the spiral groove.
[0012] Preferably, the end of the limiting post is equipped with a roller, which is located within the spiral groove. This design uses a roller to move within the spiral groove instead of the limiting post, which reduces wear and increases service life.
[0013] Preferably, the two types of stirring blades are spaced apart along the axial direction of the stirring shaft. The vertical spacing can improve the uniformity of materials at different vertical heights during stirring.
[0014] Preferably, the driving device is a bidirectional motor located at the top of the vessel, and the bidirectional motor is connected to the top of the stirring shaft.
[0015] Preferably, the vessel body includes a tank at the bottom and a detachable lid at the top of the tank. The lid is provided with several feeding pipe joints and a pressure gauge. The side wall of the tank is provided with a partition and a temperature sensor for monitoring the internal temperature of the tank. A set of heating pipes communicating with the internal space of the partition are provided at the partition.
[0016] Preferably, a discharge port is provided at the bottom of the tank, and a ball valve is provided at the discharge port.
[0017] Compared with the prior art, the advantages of this utility model are as follows: This application sets two sets of fixed stirring blades and movable stirring blades to stir the material during stirring, and drives the movable stirring blades to change their height and horizontal position by intermittently rotating forward and reverse by the driving device. Compared with pure fixed blades, the stirring effect is better, the material is mixed more evenly, and it is beneficial to the saponification reaction. Attached Figure Description

The first type of stirring blade is a fixed stirring blade 301 fixed to the stirring shaft 300, and the second type of stirring blade is a movable stirring blade 302 movably mounted on the stirring shaft 300. The side wall of the stirring shaft 300 has a spiral groove. The movable stirring blade 302 has a limiting post extending into the spiral groove. When the driving device 20 drives in the forward direction, the spiral post of the movable stirring blade 302 is located at the highest end of the spiral groove. When the driving device 20 drives in the reverse direction, the spiral post of the movable stirring blade 302 is located at the lowest end of the spiral groove. This solution uses two sets of fixed stirring blades 301 and movable stirring blades 302 to stir the material during stirring. The movable stirring blades 302 are driven by the intermittent forward and reverse rotation of the drive device 20 to change their height and horizontal position. Compared with pure fixed blades, the stirring effect is better and the material is mixed more evenly, which is conducive to the saponification reaction.
