Abstract
Description
Technical Field
[0001] The utility model relates to the field of ceramic powder granulation, in particular to a dry granulation tower. Background Art
[0002] The ceramic industry often uses spray drying tower technology to prepare powders. Specifically, a feeding device is required to cooperate with a distributor to feed the powder into the granulation tower and fully disperse it. However, in practice, because the granulation tower is relatively large, the distributor alone is still not enough to ensure that the powder is fully dispersed, and the powder is also easy to adhere to the inner wall of the granulation tower, which is not only unhygienic but also wasteful. In particular, the humidification process in the granulation tower is prone to form large water droplets in the granulation tower, thereby producing oversized particles. Once the sticky wall is too thick to form a sticky wall layer, this sticky wall layer is easy to collapse, resulting in unstable discharge and directly affecting product quality.

[0030] Figure 1 It is a three-dimensional diagram of an embodiment of the utility model, referring to Figure 1 One embodiment of the utility model provides a dry granulation tower, which prepares ceramic particles through a dry powder making process.
[0031] Further, see Figure 1 , Figure 2 The utility model comprises a dry granulation tower 100, the upper side of the tower body 100 is used as an input side, and the lower side of the tower body is used as an output side. A distributor 300 is arranged on the input side, and the distributor 300 delivers powder from the input side and disperses it in the tower body 100. The powder is humidified in the tower body 100 (the humidification process can refer to other dry granulation devices in the prior art) to form granules, and the prepared granules are discharged from the output side.
[0032] Furthermore, a swirl injection pipe 210 is provided on the side wall of the tower body 100 , and the swirl injection pipe 210 is connected to the swirl fan 200 . When the swirl fan 200 is started, the airflow formed is injected into the tower body 100 through the swirl injection pipe 210 .
[0033] Further, refer to Figure 3 , Figure 4 The tower body 100 has a swirl guide cavity 130, which has a cavity. The swirl guide cavity 130 includes an outer cavity plate 131 and an inner cavity guide plate 132, which define an annular cavity of the swirl guide cavity 130, and the annular cavity surrounds the tower body 100. The swirl guide cavity 130 is connected to the swirl injection pipe 210, and the airflow forms a swirl in the swirl guide cavity 130, that is, after the airflow formed by the swirl fan 200 is started and injected into the swirl guide cavity 130 through the swirl injection pipe 210, a swirl can be formed in an annular shape around the tower body 100 under the guidance of the swirl guide cavity 130.
[0034] Furthermore, an air outlet 134 is left at the lower side of the swirl guide cavity 130 , and the air outlet 134 is connected to the inner cavity of the tower body 100 . The swirl formed in the swirl guide cavity 130 enters the inner cavity of the tower body 100 through the air outlet 134 .
[0035] In actual operation, the distributor 300 is started to feed the powder from the input side and initially spread it in the tower body 100. At the same time, the cyclone fan 200 is started to form a cyclone in the cyclone guide chamber 130 and enter the tower body 100 from the lower air outlet 134. The above-mentioned cyclone allows the particles to collide and combine more fully during the humidification process in the tower body 100, and the more stable cyclone can ensure that the formed particles are more uniform. In addition, since the airflow of the cyclone guide chamber 130 can form an air cushion on the inner wall of the tower body 100 after being ejected from the air outlet 134, the cyclone air cushion can prevent the atomized water and powder in the humidification process from sticking to the inner wall of the tower body 100, thus avoiding the collapse of the sticky wall layer formed on the inner wall of the tower body 100 and affecting the discharge, thereby ensuring product quality.
[0036] It must be noted that the flow rate of the swirl air cushion formed on the inner wall of the tower body 100 can be flexibly adjusted according to actual generation needs, which will not be described in detail here.

[0038] In this embodiment, optionally, the swirl directions output by the swirl guide cavities 130 of each layer are consistent. For example, the swirls formed by the swirl guide cavities 130 of each layer uniformly rotate clockwise or counterclockwise around the inner cavity of the tower body 100 when viewed from a top view.
[0039] Some embodiments, see Figure 3 , Figure 4 An annular opening is left between the outer plate 131 and the lower side of the inner guide plate 132, and a plurality of outlet connectors 133 are arranged in the annular opening, and the gaps between the outlet connectors 133 serve as outlets 134. The swirl of the swirl guide cavity 130 is ensured to maintain the swirl state due to inertia from the outlet 134, and an air cushion is effectively formed on the inner wall of the tower body 100, and this airflow is relatively downward to prevent powder or particles from rebounding upward.
[0040] Some embodiments, see Figure 4 The air outlet connector 133 is a long strip structure, and a guide hole structure is formed between the air outlet connectors 133 as the air outlet 134, which is equivalent to forming a long guide hole to guide the air outlet 134 to discharge air, ensuring that the formed swirl air cushion is oriented in the appropriate direction without causing turbulence and affecting the granulation effect.
[0041] In some embodiments, the wall surface of the tower body 100 serves as the outer cavity plate 131 , and the outer cavity plate 131 of the tower body 100 is connected to the inner cavity guide plate 132 by welding.
[0042] In some embodiments, the outer cavity plate 131 and the inner cavity guide plate 132 are respectively connected to the tower body 100 by welding.
[0043] In some embodiments, a connecting plate 135 is provided on the lower side of the intra-cavity guide plate 132, and the air outlet connector 133 is connected to the connecting plate 135 to ensure that the air outlet connector 133 is firmly connected, especially when the inner walls of the tower body 100 on the upper and lower sides of the swirl guide cavity 130 are in different directions, the structure of the swirl guide cavity 130 can also be ensured to be sufficiently stable.
[0044] Some embodiments, see Figure 1 , Figure 2 The tower body 100 is provided with a feed hole 120 on the upper side thereof, which is connected to the distributor 300. Figure 3 A top guide cover 180 is arranged at the lower side of the feed hole, the upper side of the top guide cover 180 surrounds the feed hole 120, the lower side of the top guide cover 180 is connected to the inner wall of the tower body 100, and the top guide cover 180 is a frustum cone cylindrical structure, so that the powder output from the distributor 300 can be guided to fully fall for the granulation process and avoid adhering to the upper side of the tower body 100.
[0045] In this embodiment, optionally, the top guide cover 180 is detachably installed in the tower body 100 .
[0046] Some embodiments, see Figure 1 , Figure 2 The swirl injection pipe 210 is connected to the swirl guide cavity 130 via a tangential air inlet pipe 220 , and the tangential air inlet pipe 220 extends in a horizontal direction to ensure that a swirl can be stably formed in the swirl guide cavity 130 .
[0047] Some embodiments, see Figure 1 An outer support plate 140 is disposed on the upper side of the outer side of the tower body 100 , and a stand 150 is disposed on the lower side of the outer support plate 140 . The tower body 100 is supported to stand or be fixedly installed by the stand 150 .
[0048] In this embodiment, optionally, the stand 150 includes columns 151 and a crossbar 152 , wherein the crossbar 152 is located between the columns 151 , and the columns 151 are connected to the outer support plate 140 , so that the overall structure of the stand 150 is sufficiently strong and reliable.
[0049] In this embodiment, optionally, the stand 150 also includes a horizontal plate 153, which facilitates the installation of the cyclone fan 200 or other devices.
[0050] In some embodiments, a hook 160 is further provided between the stand 150 and the outer side of the tower body 100 , and a buffer spring 161 is provided on the hook 160 , which not only ensures that the tower body 100 is firmly installed in the stand 150 , but also enables the vibration generated by the tower body 100 during operation to be buffered by the buffer spring 161 .
[0051] Some embodiments, see Figure 2 The tower body 100 includes a plurality of tower body components 110 from top to bottom. The tower body components 110 are provided with splicing rings 111. Adjacent tower body components 110 are connected together through the splicing rings 111.
