Description

Technical Field

[0001] This utility model belongs to the field of granulation technology, specifically relating to a condensation shot peening granulation device and granulation mechanism. Background Technology

[0002] The condensation shot peening granulation equipment is an innovative piece of equipment that combines spray drying and mechanical impact granulation technologies. It is mainly used to process liquid or powdered raw materials into uniform granules.

[0003] Existing condensation shot peening granulation equipment typically sprays molten material from the top of a condensation tower towards the tangent of the tower, simultaneously with a condensing fan. The fan's outlet direction is towards the bottom of the tower, causing the droplets to rotate and condense along the inner wall. Once condensed into pellets, they are discharged from the outlet at the bottom of the tower. This granulation method works well for producing larger particles (0.5mm-2mm), but for producing smaller particles (0.15mm-0.5mm), the smaller droplets are more easily blown by the condensing air during their rotation and fall, causing them to fall quickly and reducing the condensation time, resulting in incomplete condensation.

[0004] Therefore, a condensation shot peening granulation device and granulation mechanism are designed to solve the technical problem of incomplete droplet condensation when producing particles with small particle size (0.15mm-0.5mm) in the prior art.

[0005] 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

[0052] Existing condensation shot peening granulation equipment typically sprays molten material from the top of a condensation tower towards the tangent of the tower, simultaneously with a condensing fan. The fan's outlet direction is towards the bottom of the tower, causing the droplets to rotate and condense along the inner wall. Once condensed into pellets, they are discharged from the outlet at the bottom of the tower. This granulation method works well for producing larger particles (0.5mm-2mm), but for producing smaller particles (0.15mm-0.5mm), the smaller droplets are more easily blown by the condensing air during their rotation and fall, causing them to fall quickly and reducing the condensation time, resulting in incomplete condensation.

[0053] Based on the above research, this disclosure provides a condensation shot peening granulation device and granulation mechanism. By setting up a granulation mechanism, a pressure spray gun is set at the output end of the first particle conveying pipe, and the output end of the pressure spray gun is vertically upward and opposed to the vertically downward condensing air. The molten material is sprayed out from the nozzle of the pressure spray gun under high pressure to achieve uniform atomization. The small particles and the cold air are in convective contact, and the particles are carried and diffused by the airflow, which slows down the gravity settling speed, so that the droplets have enough time to condense into granules.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] In some embodiments, such as Figure 1 and Figure 2 As shown, for different particle sizes produced, such as when the required particle size is small (0.15mm-0.5mm), the pressure pump 213 on the first feed pipe 211 is started. The pressure pump 213 draws the high-temperature liquid in the melting tank 22 and pumps it into the pressure spray gun 214. The high-temperature liquid is sprayed out from the nozzle of the pressure spray gun 214 under high pressure to achieve uniform atomization. At the same time, the condenser fan 13 is started to blow the condensing air towards the bottom of the condensing tower 1 through the condensing air pipe 14. The condenser fan 13 outputs cold air with a temperature ≤-10℃ and a wind speed ≥15m / s. The output end of the pressure spray gun 214 is facing upward and opposite to the output end of the condensing air pipe 14. The axial distance between the outlet of the pressure spray gun 214 and the outlet of the condensing air pipe 14 is 5-15cm. At this time, the small particles and the cold air are in convective contact. The particles are carried and diffused by the airflow, which slows down the gravity settling speed, so that the droplets have enough time to condense into particles.

[0058] In some embodiments, such as Figure 1 and Figure 2As shown, when the required particle size is relatively large (0.5mm-2mm), the gear pump 210 on the second particle conveying pipe 212 is started to draw the high-temperature liquid in the melting tank 22 through the second particle conveying pipe 212. The end of the second particle conveying pipe 212 located inside the condensing tower 1 faces the inner wall of the centrifuge cylinder 12, so the high-temperature liquid will be pumped into the centrifuge cylinder 12. At this time, the rotary motor 10 is started, and the output end 11 rotates, thereby driving the centrifuge cylinder 12 to rotate. Under the centrifugal action, the high-temperature liquid is squeezed out from several extrusion holes opened on the inner wall of the centrifuge cylinder 12 into droplets. At this time, the condensing air blown out by the condensing fan 13 condenses the droplets into particles. Since each particle is rotated and thrown out, it will rotate and move down along the inner wall of the condensing tower 1 until it is discharged and collected from the discharge pipe 15 at the bottom of the condensing tower 1.

[0059] In some embodiments, such as Figure 2 As shown, the cyclone separator 3 is started simultaneously during the granulation process, and an induced draft fan is installed at the top of the cyclone separator 3. The fan draws out the tiny particles (i.e., the incompletely granulated particles, which are in powder form) in the condenser tower 1 through the feed pipe 30. The particles are then drawn into the cyclone separator 3 for separation, and introduced into the feed pipe 33 through the discharge pipe 32. The feed fan 31 then transports the particles to the melting tank 22 to melt them into liquid and regranulate them. A stirring motor 20 can be installed at the top of the melting tank 22. The high-temperature molten material in the melting tank 22 is continuously stirred by rotating the stirring shaft to prevent solidification.

[0060] In some embodiments, a heating layer is provided on the outer wall of the first and second particle conveying pipes 211 and 212 to prevent the material from solidifying and blocking the pipe during the conveying process. The gear pump 210, pressure pump 213, pressure spray gun 214 and cyclone separator 3 mentioned in the above description are all existing devices, and their specific structures and connection methods with surrounding components are all existing technologies, which will not be described in detail here.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.
