[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] like Figure 1 As shown, a crystallization granulation catalytic softening fluidized bed seed crystal feeding system includes:

[0029] Container 1, with an overflow valve 7 installed on one side of the upper part of the container 1 and a water outlet pipe 4 connected to one side of the lower part of the container 1;

[0030] Water inlet container 2 is connected to the bottom of container 1, and water inlet pipe 3 is connected to the bottom of water inlet container 2;

[0031] A partition plate 5 is provided between the container 1 and the water inlet container 2. The partition plate 5 is provided with a plurality of holes 5.1 for connecting the container 1 and the water inlet container 2.

[0032] Hybrid structure 6 is installed on each hole 5.1.

[0033] Specifically, water containing seed crystals enters the inlet container 2 through the inlet pipe 3, and then the seed crystals and water are mixed evenly through the mixing structure 6. The mixed water then enters the container 1 and is discharged through the outlet pipe 4 to the crystallization granulation fluidized bed for feeding. If the container 1 is full, the overflow valve 7 at the top of the container 1 will drain the excess water.

[0034] The outlet pipe 4 is positioned higher than the inlet pipe 3. A pump is installed on the outlet pipe 4 to extract the liquid from container 1.

[0035] Specifically, the mixing structure 6 is located between the outlet pipe 4 and the inlet pipe 3. Water will be mixed and homogenized after passing through the mixing structure 6, and then discharged from the outlet pipe 4.

[0036] like Figure 2 , 3 As shown, the hybrid structure 6 includes:

[0037] The cylinder 6.3 is installed on the hole 5.1 of the partition plate 5, and the top of the cylinder 6.3 is provided with an outlet I6.4;

[0038] The cover tube 6.1 is fitted over the outside of the cylinder body 6.3, and the cover tube 6.1 is provided with multiple outlets II6.2 for connecting to the container 1.

[0039] The cover cylinder 6.1 includes a circular cylindrical structure, with a cover plate disposed on the top of the circular cylindrical structure, and the outlet II 6.2 is disposed on the circular cylindrical structure. The diameter of the circular cylindrical structure is larger than the diameter of the cylinder body 6.3.

[0040] Specifically, the working principle of the mixing structure 6 is as follows: After water enters the water inlet container 2, it is stored in the water inlet container 2, and then slowly enters the cylinder 6.3 from the hole 5.1 of the partition plate 5, and is discharged from the outlet I 6.4 at the top of the cylinder 6.3. The water flows back down in the cover cylinder 6.1 and is discharged from the outlet II 6.2. First, because the water inlet velocity of the water inlet pipe 3 is greater than the water outlet velocity of the mixing structure 6, the water pressure at outlet I 6.4 and outlet II 6.2 in the mixing structure 6 increases, thereby increasing the water flow velocity in the mixing structure 6. The water flow moves back and forth rapidly in the mixing structure 6, thus mixing the seed crystals and water evenly before entering the container 1.

[0041] The top of container 1 is an open structure, meaning that the top of container 1 is not sealed and is open.

[0042] The bottom outer side of container 1 is mounted on support 8 for installing the crystallization granulation catalytic softening fluidized bed seed crystal feeding system. A liquid level gauge 9 is installed on the outer side of container 1.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
