Description

Technical Field

[0001] This utility model belongs to the field of centrifugal granulation technology, specifically relating to a centrifugal condensation granulation system and a heat preservation mechanism. Background Technology

[0002] Existing centrifugal condensation granulation systems typically involve introducing high-temperature liquid materials into a centrifugal disc, and then rotating the disc to expel the material through holes on its surface and condense it into granules. However, before centrifugal granulation begins, the temperature of both the centrifugal disc and the conveying pipe is lower than that of the liquid material. When the high-temperature liquid material is introduced into the conveying pipe, the portion of the high-temperature liquid material in contact with the inner wall of the conveying pipe will preferentially solidify and adhere to the inner wall of the conveying pipe, thus clogging the conveying pipe.

[0003] Therefore, a centrifugal condensation granulation system and a heat preservation mechanism are designed to solve the technical problem in the prior art where the temperature of the conveying pipe before granulation is lower than that of the liquid material, causing the liquid material to solidify and block the conveying pipe on the inner wall during the conveying process.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0007] In one optional embodiment, the heat preservation mechanism includes: An insulation pipe is fitted over the outside of the material conveying pipe; A gas delivery pipe is installed on the outer wall of the insulation pipe, which is suitable for introducing hot air into the inner wall of the insulation pipe to keep the liquid material flowing in the delivery pipe warm.

[0009] In one optional embodiment, the top end of the feed tube is connected to the lower end face of the base, and the bottom end of the feed tube is connected to the hemispherical atomizing disc via an external bearing. The bottom end of the rotating shaft is connected to the hemispherical atomizing disc by bolts.

[0010] In one alternative embodiment, the discharge end of the conveying pipe penetrates the outer wall of the guide pipe and is located inside the guide pipe to facilitate the introduction of liquid materials into the guide pipe.

[0028] Research has revealed that existing centrifugal condensation granulation systems typically involve introducing high-temperature liquid materials into a centrifugal disc, which is then rotated to expel the material through openings on its surface and condense it into granules. However, before centrifugal granulation begins, the temperatures of both the centrifugal disc and the conveying pipe are lower than those of the liquid material. When the high-temperature liquid material is introduced into the conveying pipe, the portion of the high-temperature liquid material in contact with the inner wall of the pipe will preferentially solidify and adhere to the inner wall, thus affecting the material transport and subsequent granulation efficiency.

[0029] Based on the above research, this disclosure provides a centrifugal condensation granulation system and a heat preservation mechanism. By providing a heat preservation mechanism that is sleeved on the outer wall of the conveying pipe, the conveying pipe is kept warm before condensation granulation begins. This allows the high-temperature liquid material to flow normally when it is introduced into the conveying pipe, and avoids the liquid material from solidifying and blocking the conveying pipe due to an excessive temperature difference between the conveying pipe and the liquid material.

[0030] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] In some embodiments, such as Figure 1As shown, before starting condensation granulation, the gas delivery pipe 30 is connected to an external gas tank (not shown in the figure). The high-temperature gas in the gas tank enters the insulation pipe 33 through the gas delivery pipe 30. The outer wall of the material delivery pipe 7 heats the material delivery pipe 7. At this time, the exhaust solenoid valve 310 is closed and the gas guide solenoid valve 320 is opened. The high-temperature gas in the insulation pipe 33 enters the material guide pipe 20 through the gas guide pipe 32 and finally contacts the inner wall of the hemispherical atomizing disk 4 to heat the hemispherical atomizing disk 4. This avoids the temperature difference between the inner wall of the material delivery pipe 7 and the high-temperature liquid material being too large when the high-temperature liquid material enters the material delivery pipe 7, which would cause the liquid material to solidify in the material delivery pipe 7. At the same time, it also avoids the high-temperature material from directly solidifying in the hemispherical atomizing disk 4 and clogging the hemispherical atomizing disk 4 when it comes into contact with the inner wall of the hemispherical atomizing disk 4. When condensation granulation begins, motor 1 is started, and the torque is changed through gearbox 12, increasing the adjustable speed range of motor 1's output. At this time, rotating shaft 10 rotates accordingly, which in turn drives the hemispherical atomizing disk 4 connected to the bottom of rotating shaft 10 to rotate. High-temperature liquid material enters through the feed end 70 of conveying pipe 7 and is discharged from the discharge end 71 into the guide pipe 20, finally falling into the interior of hemispherical atomizing disk 4. As hemispherical atomizing disk 4 rotates, liquid material is squeezed out from the atomizing holes on hemispherical atomizing disk 4 to form small particles. The formed small particles solidify upon contact with cold air, thus achieving granulation. (The source of cold air includes, but is not limited to, using a cold air blower, with the airflow direction opposite to the falling direction of the small particles. This is existing technology and will not be elaborated further here.) When condensation granulation begins, the gas guiding solenoid valve 320 is closed and the exhaust solenoid valve 310 is opened. At this time, the hot air in the insulation pipe 33 is discharged from the exhaust pipe 31. The hot air continuously enters through the gas conveying pipe 30 and exits through the exhaust pipe 31, so that the temperature is kept constant when the high-temperature liquid material enters the conveying pipe 7. At the same time, the hot air is prevented from blowing towards the hemispherical atomizing disk 4 and affecting the formation of small particles extruded from the atomizing holes.

[0034] As another feasible implementation, a conical cylinder 5 is provided at the bottom of the rotating shaft 10, and a bolt 6 is inserted into the threaded hole 51 and connected to the bottom end of the rotating shaft 10. At this time, the rotation of the rotating shaft 10 drives the conical cylinder 5 to rotate, and the liquid material entering the conical cylinder 5 from the feed pipe 20 is squeezed out from several extrusion holes 50 on the inner wall of the conical cylinder 5 to form small particles, which are eventually solidified into granules.

[0035] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0037] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0038] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0039] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
