Description

Technical Field

[0001] The utility model relates to the field of electrodes, and more particularly to a spray granulator. Background Art

[0002] Spray granulator is a granulation equipment that atomizes the slurry and sprays it into the granulation chamber. Under the action of the spray hot air, the slurry is dried and agglomerated to obtain granules.

[0003] Currently, spray granulators used in the production of capacitor dielectric electrodes include a slurry supply device, an atomizing device, a granulation chamber, and a heating device for heating the granulation chamber. The slurry supply device is connected to the atomizing device via a feed pipe. The atomizing device is located at the top of the granulation chamber, and a discharge port is provided at the bottom of the granulation chamber. The heating device heats the granulation chamber, maintaining the interior of the granulation chamber at the required high temperature for spray granulation. The slurry in the slurry supply device is transported to the atomizing device via the feed pipe, where it is atomized and sprayed into the granulation chamber. The hot air spray dries and agglomerates the granules, producing capacitor dielectric particles.

[0004] However, the existing spray granulator has the following problems when in use: although it can dry and shape its materials, the temperature of the materials is relatively high when they are discharged and they cannot be packaged directly. In the cooling process after the materials are discharged, the water vapor in the high-temperature materials condenses again and may cause the materials to agglomerate, resulting in low work efficiency and the risk of scalding the operators.

[0005] Therefore, the utility model proposes a spray granulator. Utility Model Content

[0022] The following is a combination of the appended examples of the present invention Figures 1-4 , clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0023] See also Figure 1-4The top of the device body 1 is embedded with an atomizing mechanism 5, and the top of the atomizing mechanism 5 is fixedly connected with a feeding pipe 6. The atomizing mechanism 5 includes a centrifugal atomizing disk and an atomizer. The outside of the device body 1 is connected with a matching air supply duct 4 and an air supply branch pipe 12. The air supply branch pipe 12 is connected to the atomizing mechanism 5 at the same time. The air supply duct 4 and the air supply branch pipe 12 are respectively equipped with an air supply motor and a heating mechanism. The inside of the device body 1 is sequentially provided with a granulating chamber 10, a cooling chamber 11 and an air supply chamber 13 from top to bottom. The outside of the atomizing mechanism 5 is surrounded by a guide ring seat 9, and the bottom end of the guide ring seat 9 is fixedly connected with a guide inner cover 7. The outside of the guide ring seat 9 is surrounded by a forming outer cover 8. The bottom of the device body 1 is fixedly connected with a material guide pipe 14, and the inner sides of the cooling chamber 11 and the air supply chamber 13 are respectively fixedly connected with cooling chamber 11 and cooling chamber 13. The cooling fins 16 are embedded in the outer side of the cooling chamber 11, and the air supply chamber 13 is fixedly connected with an air supply base 17. An air supply cavity 18 is provided inside the air supply base 17, and an air supply head 19 is fixedly connected to the top of the air supply cavity 18. The outer side of the air supply base 17 is connected to the air supply duct 4 at the same time. When the device is in use, the material is exposed to the hot air flow for the first time after passing through the granulation chamber 10. After forming, the external normal temperature air flow delivered from the bottom of the device body 1 continues to flow upward after passing through the air supply cavity 13 and the cooling chamber 11, so that the material is suspended in the device body 1 and the material is continuously cooled. Among them, the granular materials with larger diameters are suspended at a lower height in the cooling chamber 11 and the air supply cavity 13 when encountering the rising air flow, so that the larger granular materials are discharged outwardly from the material guide pipe 14. After the subsequent cooling is completed, the smaller granular materials are concentrated and discharged from the material guide pipe 14 again.

[0024] In the embodiment of the present utility model, the bottom end of the air supply branch pipe 12 is simultaneously embedded in the top of the device body 1 and extends into the top of the granulation chamber 10. The guide ring seat 9 and the atomization mechanism 5 are movably connected, and the guide inner cover 7 is set as a conical cover, and the side section is "L"-shaped and expanded outward. The guide inner cover 7 also surrounds the bottom of the atomization mechanism 5, and the guide inner cover 7 is located above the inner side of the molding outer cover 8. The inner side of the bottom end of the molding outer cover 8 is triangular and convex. The guide ring seat 9 is used to facilitate the rapid and stable rotation of the centrifugal atomizing disk in the atomization mechanism 5 above the granulation chamber 10. The guide inner cover 7 is used to guide and surround the molded granular material. The molding outer cover 8 is used to concentrate heat, which is beneficial to the molding of the material.

[0025] The material enters the atomizing mechanism 5 from the feeding pipe 6 and is thrown out through the centrifugal atomizing disk in the atomizing mechanism 5. During this process, the rotation of the atomizing mechanism 5 is enhanced through the guide ring seat 9 to enhance stability. At the same time, the external hot air flow is sent into the granulation chamber 10 through the air supply branch pipe 12 to form the material. The formed material is concentrated downward through the guide inner cover 7. At the same time, the external hot air flow flows downward from the top of the device body 1. Since the bottom end of the forming outer cover 8 is arranged in an inwardly concave triangular shape, the hot air flow can be effectively concentrated to avoid heat loss and ensure material molding.

[0026] The cooling inner cover 15 is composed of an arc-shaped cover body in the upper section and a vertical "Z"-shaped cover body in the lower section. The cooling fins 16 are located outside the cooling inner cover 15, in the middle section of the device body 1, and the cooling fins 16 are horizontally penetrated through the cooling inner cover 15. The cooling inner cover 15 is used to diffuse heat and guide the cold air flow at the same time, and the cooling fins 16 are used to cool the molding material.

[0027] When the external air flow is sent into the device body 1, part of the air flow is sent into the top of the device body 1 after being heated, and part of the air flow is sent into the bottom of the device body 1 at normal temperature. After the normal temperature air flow is sent into the device body 1 from the bottom, it is sent into the cooling chamber 11 through the air supply chamber 13. When in the cooling chamber 11, the "Z"-shaped cover body of the lower section of the cooling inner cover 15 guides this part of the air flow upward, and the arc-shaped cover body of the upper section can enable the normal temperature air flow to quickly cool down the heat conducted from the top of the inside of the device body 1, and cooperate with the cooling fins 16 to ensure the cooling temperature in the cooling chamber 11, and then ensure that the cooling chamber 11 cools down the molding material.

[0028] The air supply base 17 is set in an inverted trapezoidal base, the air supply cavity 18 is set to be inclined upward, the air supply head 19 is opened outwardly and inclined, and the guide inner cover 20 is set in a conical cover, which is arranged inside the bottom end of the device body 1. The air supply cavity 18 cooperates with the air supply head 19 to achieve the effect of diffusing and guiding the normal temperature airflow transported from the outside, and the guide inner cover 20 achieves the effect of concentrating the normal temperature airflow transported from the outside.

[0029] The external normal temperature air flow enters the air supply base 17, is discharged outward in a diffused manner through the air supply cavity 18 and the air supply head 19, and is transported upward from the air supply cavity 18. The guide inner cover 20 ensures the stability of the air flow transportation.
