[0002] A glass-lined reactor is a reaction vessel with a corrosion-resistant inner lining, which is widely used in industries such as chemical engineering, medicine, and food processing. The inner wall of this reactor is coated with a layer of glass material, usually borosilicate glass, to provide protection against various chemical media. The inner wall of the glass-lined reactor is smooth, and its main characteristics include corrosion resistance, high temperature resistance, and easy maintenance.

[0003] The glass-lined reactor in the prior art is as Figure 1 shown. The glass-lined anchor-type stirring paddle inside the glass-lined reactor rotates driven by a motor. It can neither stir the materials in the glass-lined reactor up and down, thus affecting the reaction between materials in different regions, nor turn up the materials at the bottom of the glass-lined reactor, resulting in serious sedimentation of the bottom materials. When the materials sediment seriously, it is necessary to stop the machine and poke open the materials to make the reacted materials unload normally, which causes the unloaded materials to be easily contaminated by foreign objects and microorganisms.

[0004] To overcome the problems in the prior art, the utility model provides a stirring paddle and a glass-lined reactor applied to the sodium aminofolate process. The paddle blades can stir the materials in the glass-lined reactor in two directions, vertical and horizontal, and the materials in each region can be stirred, enabling the materials to react more fully. At the same time, the materials are not easy to precipitate at the bottom, facilitating subsequent unloading. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0026] As Figures 2 - 4 shown, a stirring paddle applied to the methotrexate sodium process includes a blade main shaft 1, a first blade 2 and a second blade 3. The axis of the first blade 2 is arranged parallel to the horizontal plane, the axis of the second blade 3 is arranged at an angle of 60°-80° with the horizontal plane, and the blades of the first blade 2 and the second blade 3 are both inclined at 45°.

[0027] In this embodiment, the axis of the second blade 3 is arranged at an angle with the horizontal plane, and this angle is preferably 70°.

[0028] Since the blades of the first blade 2 and the second blade 3 are both inclined at 45°, and the blades of the first blade 2 and the second blade 3 are arranged oppositely, that is, not parallel and inclined at 45°, therefore, the blades of the first blade 2 and the second blade 3 can not only stir the material in the horizontal direction, but also stir the material in the vertical direction, and can also cooperate with each other to stir the material multiple times. Furthermore, the stirring of the material is made more uniform and the material reacts more fully.

[0029] Specifically, since the axis of the second blade 3 is set at 70° to the horizontal plane and the blade of the second blade 3 is inclined at 45°, the material at the bottom can be agitated upward by the second blade 3, and the blade of the first blade 2 pats the material lifted by the second blade 3, making the reaction of the material more sufficient. Further, the first blade 2 inclined at 45° can drive the reacted material upward, preventing the reacted material from settling at the bottom of the reaction kettle body 4, which is beneficial to subsequent discharging.

[0030] The material inside the utility model is agitated both horizontally and vertically, making the reaction between the materials more sufficient, and the reacted material can meet the standards; the material at the bottom is driven upward under the cooperation of the first blade 2 and the second blade 3, and it is not easy to settle at the bottom, which is convenient for subsequent discharging.

[0031] The first blade 2 is arranged in the direction close to the second blade 3 and is located at 1 / 3 of the blade main shaft 1; the second blade 3 is located at the bottom of the blade main shaft 1. Further, in order to make the reaction of the reactants more sufficient, a plurality of first blades 2 and second blades 3 can be sequentially arranged on the blade main shaft 1.

[0032] The blades of the first blade 2 and the second blade 3 are at least 3, and the length of the blades is between 250 mm and 300 mm. In this embodiment, the length of the blades is preferably 260 mm, which is close to the inner wall of the reaction kettle body 4, enabling the blades to contact the material over a larger area and improving the stirring efficiency of the material.

[0033] The blade main shaft 1, the first blade 2 and the second blade 3 are all coated with glass enamel, making the stirring paddle have the advantages of corrosion resistance, high temperature resistance, etc., and can realize the stirring of more materials.

[0034] From Figure 4 Viewed from the bottom view of the stirring paddle, the blades of the first blade 2 and the blades of the second blade 3 are arranged alternately at intervals, and the angles between the blades of the first blade 2 and the blades of the second blade 3 arranged at intervals are the same.

[0035] A stepped portion 11 is formed on the side of the blade main shaft 1 away from the first blade 2, and an external thread is formed on the stepped portion 11, and the stepped portion 11 facilitates the installation of the stirring paddle in the reaction kettle body 4.

[0036] Specifically, the second blade 3 is located at the bottom of the blade main shaft 1, which is convenient for stirring the material at the bottom of the reaction kettle body 4 to prevent material precipitation at the bottom of the reaction kettle body 4, while the first blade 2 is located at 1 / 3 of the blade main shaft 1, which is convenient for cooperating with the first blade 2 at the bottom to stir the stirred material more sufficiently again, which is beneficial to a more sufficient reaction between the materials.

[0037] Among them, the blades of the first blade 2 and the blades of the second blade 3 are arranged alternately at intervals, and the angles between the blades are the same, so that the materials in each area of the reactor body 4 can be stirred, and the materials in the same area can be stirred multiple times by the blades at different heights, greatly improving the reaction efficiency of the materials.

[0039] The blade main shaft 1 is arranged in the center of the reactor body 4, which is beneficial to the stirring paddle to stir the materials evenly.

[0040] Specifically, the speed reduction motor 6 controls the rotation of the stirring paddle through the coupling 7. The feeding port 8 with a height higher than the height of the kettle cover 5 avoids the materials from escaping from the reactor body 4 while placing the materials. The on-line detection port 10 is used to observe the dynamic reaction of the materials in the reactor body 4 in real time, and the discharging port 9 is used to transfer the materials after the reaction to the designated area.
