Description

Technical Field

[0001] The invention relates to the technical field of dripping, in particular to a bead-forming adding device and an adding method for esterification raw material liquid. Background Art

[0002] 1. Limitations of existing esterification raw material addition methods:

[0003] In the chemical industry, especially in the production process related to esterification reaction, the way of adding raw materials has a crucial impact on the efficiency, quality and cost control of the reaction. The traditional way of adding esterification raw materials is usually to directly add liquid raw materials into the reaction system in the form of continuous flow or simple dropwise addition. However, this method has many problems.

[0004] 2. Problems with traditional addition methods

[0005] Uneven mixing problem:

[0006] In the process of direct dropwise addition or continuous flow addition, since there is no sufficient dispersion and mixing mechanism for the raw material liquid when entering the reaction system, the long-term dropwise addition process can easily lead to the local concentration of the raw material in the reaction system being too high or too low, resulting in inconsistent dropwise concentration and affecting product quality.

[0007] Residue and waste issues:

[0008] For ordinary dripping methods, liquid may remain on the surface of the adding device. For example, when using a simple dropper or pipe for dripping, liquid is likely to remain at the mouth of the dropper or the outlet of the pipe. As time goes by, this residual liquid will not only affect the accuracy of the next dripping, but also cause a waste of raw materials and increase production costs, especially for some expensive esterification raw materials, this waste is more significant.

[0009] Flow control accuracy problem:

[0010] Traditional addition devices often have difficulty in achieving high-precision control when controlling liquid flow. The continuous flow addition method may be affected by factors such as pressure fluctuations and changes in pipeline resistance, resulting in unstable flow; and the simple drip addition method, although relatively stable, is difficult to accurately adjust the dripping speed and dripping amount according to the real-time needs of the reaction, and cannot well meet the requirements for precise control of raw material addition in complex esterification reactions.

[0011] Therefore, a device and method for adding esterification raw material liquid beads are needed to solve the above problems. Summary of the invention

[0031] 2. The present invention forms and disappears the guide groove through the coordinated action of the electromagnet and the elastic support mechanism through the strip rod. When the guide groove is formed, the water droplets can roll down along the guide groove in an orderly manner under the action of gravity, further ensuring the orderliness and controllability of liquid addition and avoiding the problem of uneven addition caused by random flowing of liquid.

[0032] 3.

[0033] 4.

[0034] 5. The present invention effectively stirs the esterification mixed raw material liquid in the silo through the stirring rod assembly, and the vertical rod also participates in the stirring of the liquid below the silo. The double stirring action can break the stratification and sedimentation of the raw materials in the liquid, ensure that different raw materials are fully mixed in the liquid, and make the raw material composition entering the reaction system uniform.

[0035] 6. The present invention coordinates the opening and closing of the water inlet hole, the control of the electromagnet, the formation of the guide groove, the stirring and other components through the linkage mechanism of the rotating shaft, realizes an orderly workflow, ensures continuous and stable operation and improves production efficiency.

[0036] 7. The present invention realizes continuous dripping of equal amounts and homogeneity at multiple points on the circumference through continuous dripping on the circumference, so that the dripping is uniform. BRIEF DESCRIPTION OF THE DRAWINGS
