[0002] The ceramics industry often uses spray drying tower technology to prepare powders, which requires a distributor to feed the powder into a granulation tower. The distributor needs to fully disperse the powder within the granulation tower, often requiring a fan installed at the distributor outlet to break up the powder. However, in practice, this method is still insufficient to ensure sufficient powder dispersion, which in turn affects the quality of subsequent ceramic products. It also limits the feed flow rate, hindering feeding efficiency. Utility Model Content

The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number or order of the technical features indicated.

[0028] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0029] Figure 1 This is a perspective view of an embodiment of the present invention, referring to Figure 1 One embodiment of the present invention provides a granulation tower distributor, which is used to blow the powder away fully, so that the powder falls under the action of gravity and is evenly distributed into the granulation tower.

[0030] Further, refer to Figure 2The distributor of the present invention includes an outer cylindrical portion 100 and an inner cylindrical portion 200. The outer cylindrical portion 100 is sleeved on the outer side of the inner cylindrical portion 200. An annular cavity is formed between the inner wall of the outer cylindrical portion 100 and the outer wall of the inner cylindrical portion 200, so that high-pressure airflow and powder can flow in the annular cavity.

[0031] Furthermore, the outer cylindrical portion 100 has a lower opening serving as an outer cylindrical portion outlet 110. A high-pressure feed pipe serving as an outer cylindrical portion inlet 120 is connected to the outer side of the outer cylindrical portion 100. The high-pressure feed pipe feeds high-pressure air into the annular cavity, forming an annular airflow. Specifically, the high-pressure airflow enters the annular cavity within the outer cylindrical portion 100 from the outer cylindrical portion inlet 120 on the outer side of the outer cylindrical portion 100, forming an annular airflow, and then flows out from the outer cylindrical portion outlet 110 on the lower side of the outer cylindrical portion 100.

[0032] Furthermore, the lower side of the inner cylindrical portion 200 extends out of the outer cylindrical portion 100. The upper side of the inner cylindrical portion 200 serves as the inner cylindrical portion inlet 220, and the lower side of the inner cylindrical portion 200 serves as the inner cylindrical portion outlet 210. That is, fluid enters the inner cylindrical portion 200 from the inner cylindrical portion inlet 220 on the upper side of the inner cylindrical portion 200 and exits from the inner cylindrical portion outlet 210 on the lower side of the inner cylindrical portion 200. The inner cylindrical portion outlet 210 has a truncated cone-shaped opening structure. The area of ​​the horizontal cross-section of the truncated cone-shaped opening increases from top to bottom, which is equivalent to the truncated cone-shaped opening structure having an inclined surface that slopes from the upper side of the inner cylindrical portion 200 to the lower side of the outer cylindrical portion 100, forming a trumpet-shaped opening structure. This allows the pressure of the water fluid to decrease as it passes through the trumpet-shaped opening structure, while the water forms a large-scale water mist area.

[0033] In actual work, refer to Figure 3 The distributor of this utility model receives a high-pressure fluid through the outer cylindrical portion inlet 120, driving the powder into the annular cavity within the outer cylindrical portion 100. The inner cylindrical portion inlet 220 receives high-pressure water or high-pressure steam, forming an aqueous fluid. The high-pressure fluid drives the powder into the annular cavity, forming an annular airflow that ensures the powder is fully dispersed within the annular cavity. The powder then falls under gravity and is discharged from the outer cylindrical portion inlet 120. Simultaneously, when the aqueous fluid in the inner cylindrical portion 200 is discharged from the inner cylindrical portion outlet 210, it diffuses into a sufficiently large mist due to the frustum-shaped opening structure. The moisture in the powder in the mist is fully combined to form uniform and stable particles.

[0034] In some embodiments, the outer cylindrical portion outlet 110 also has a truncated cone-shaped opening structure, that is, the outer cylindrical portion outlet 110 also has a trumpet-shaped opening structure, with an inclined surface sloping from the upper side of the inner cylindrical portion 200 to the lower side of the outer cylindrical portion 100. A trumpet-shaped outlet cavity is formed between the outer cylindrical portion outlet 110 and the inner cylindrical portion outlet 210, which can make the powder more evenly dispersed in the granulation tower, rather than being concentrated in the middle of the granulation tower.

[0035] In some embodiments, an outer cylindrical portion fixing plate 111 is provided at the edge of the outer cylindrical portion output port 110 , and the distributor of the present invention is fixed on the granulation tower via the outer cylindrical portion fixing plate 111 .

[0036] In this embodiment, optionally, the outer cylindrical portion fixing plate 111 is provided with screw holes, and the outer cylindrical portion fixing plate 111 is connected to the granulation tower via screws.

[0037] In some embodiments, the outer cylindrical portion input port 120 extends in a horizontal direction, so that the high-pressure gas entering from the outer cylindrical portion input port 120 is also horizontal, which can make the powder stay in the annular cavity for a longer time and ensure that the powder is fully dispersed in the annular cavity.

[0038] In some embodiments, an outer cylindrical portion connecting pipe ring 121 is provided at the edge of the outer cylindrical portion input port 120 for connecting with a feed pipe.

[0039] In this embodiment, optionally, the outer cylindrical portion pipe ring 121 is provided with screw holes, and the outer cylindrical portion pipe ring 121 is connected to the feeder through screws.

[0040] In some embodiments, the upper side of the outer cylindrical portion 100 is a closed surface 130 that blocks the powder so that the powder remains in the annular cavity.

[0041] In some embodiments, a pressure sensor 131 is provided on the closed surface 130 to monitor the pressure inside the annular cavity. Once the pressure inside the annular cavity is abnormal, the feeding or even the machine needs to be stopped for maintenance to avoid subsequent waste of defective products.

[0042] In some embodiments, the inner cylindrical portion input port 220 extends out from the upper side of the outer cylindrical portion 100 to facilitate connection with pipelines.

[0043] In some embodiments, an inner cylindrical portion connecting pipe ring 221 is provided at the edge of the inner cylindrical portion input port 220 for connecting to the water inlet pipe.

[0044] In this embodiment, optionally, the inner cylindrical portion pipe ring 221 is provided with screw holes, and the inner cylindrical portion pipe ring 221 is connected to the water inlet pipe through screws.

[0045] In some embodiments, a wear-resistant ring cavity 300 is provided on the outer cylindrical portion 100. The wear-resistant ring cavity 300 surrounds the outer cylindrical portion 100. Cement is poured into the wear-resistant ring cavity 300 to strengthen the strength of the outer cylindrical portion 100 and prevent the outer cylindrical portion 100 from being worn by high-pressure powder and causing accidents.

[0046] In this embodiment, optionally, the cement used is corundum cement, which has high wear resistance and fire resistance, further improving safety.
