Description

Technical Field

[0001] The utility model belongs to the technical field of dryers, and in particular relates to a particle drying device and a high-shear mixing granulation dryer. Background Art

[0002] Existing granulators use vacuum suction (or manual loading) to mix the materials in a container. After adding a binder, the materials are then mixed and moved in circumferential, radial, and axial directions by a modified agitator to fully mix them. The materials are then cut into uniform, dense spherical granules by a granulating cutter. However, existing mixing granulators lack a drying function, requiring the materials to be dried in the next step. This makes operation difficult for heat-sensitive materials, which are prone to agglomeration, making unloading impossible and resulting in uneven granulation.

[0003] Therefore, a particle drying device and a high shear mixing granulation dryer are designed to solve the technical problem that the granulator in the prior art lacks a synchronous drying function during the granulation process, resulting in agglomeration during the granulation process.

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

[0054] In this document, when it is mentioned that a first component is located on a second component, this may mean that the first component may be directly formed on the second component, or that a third component may be interposed between the first component and the second component. In addition, in the drawings, the thickness of components may be exaggerated or reduced in order to effectively describe technical content.

[0055] As used herein, when an element or layer is referred to as being "located on," "engaged to," "connected to," "attached to," or "coupled to" another element or layer, it may be directly located on, engaged, connected, attached to, or coupled to the other element or layer, or there may be intervening elements or layers. Conversely, when an element is referred to as being "directly on," "directly engaged to," "directly connected to," "directly attached to," or "directly coupled to" another element or layer, there may be no intervening elements or layers. Other words used to describe the relationship between elements should be interpreted in a similar manner (e.g., "between" versus "directly between," "adjacent" versus "directly adjacent," etc.). As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0056] Herein, example embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as "at least one of..." when following a list of elements modify the entire list of elements, rather than modifying individual elements in the list. For example, the expression "at least one of a, b, and c" should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0059] Research has found that existing granulators use vacuum suction (or manual loading) to introduce materials into a container. After mixing and adding a binder, the materials are then subjected to circumferential, radial, and axial motion by a modified agitator for thorough mixing. The materials are then cut into uniform, dense spherical granules by a granulating cutter. However, existing mixing granulators lack a drying function, requiring the materials to be dried in the next step. This makes operation difficult for heat-sensitive materials, which are prone to agglomeration, making unloading impossible and resulting in uneven granulation.

[0060] Based on the above research, the embodiments of the present disclosure provide a particle drying device and a high-shear mixing granulation dryer. By providing an induced draft mechanism, when the material is put into the drying cylinder for granulation, the induced draft mechanism is used to introduce the heated air along the tangential direction of the inner wall of the drying cylinder, so that the heated air comes into contact with the moist particles over a large area and then dries the moist particles.

[0061] The defects in the above solutions are the results obtained by the inventors after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present disclosure in this article should be the contributions made by the inventors to the present disclosure during the disclosure process.

[0062] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0063] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0064] In some embodiments, as Figure 1 As shown, the material is put into the drying cylinder 1, and liquids such as adhesives are sprayed toward the drying cylinder 1 simultaneously to promote the bonding and forming of the material. The material is driven to rotate by the rotating push plate 12 for granulation. At this time, after the granules are formed, the air heater 21 is started to draw outside air into it for heating. The outside air passes through the filter 22, and impurities in the air are intercepted by the filter 22. After the air heating is completed, the blower 23 is used to pump the dry hot air into each air duct 24, and then pass through the air inlet duct 20 connected to each air duct 24, and enter the drying cylinder 1 along the tangent direction of the inner wall of the drying cylinder 1 to dry the wet granules. In order to improve the granule drying effect, the rotation direction of the dry air in the drying cylinder 1 is the same as the rotation direction of each push plate 12.

[0065] In some embodiments, as Figure 2a and Figure 2b As shown, during the preliminary granulation process, each blocking member 31 is fitted with each air inlet 18 of the drying cylinder 1. Since the curvature of one end face of the blocking member 31 facing the drying cylinder 1 is the same as the curvature of the outer wall of the drying cylinder 1, when the two are fitted, the interior of the drying cylinder 1 is sealed to prevent leakage of powder. When the particles need to be dried after forming, the driver 30 is started, and its output end drives the drive rod 32 to retract, and the drive rod 32 moves along the direction shown by F2, so that the dry hot air in the air duct 24 can pass through the air inlet 18 into the interior of the dryer 1 to dry the formed particles.

[0066] In some embodiments, as Figure 3As shown, when powder is put into the drying cylinder 1, the first rotary motor 10 is started, and its output end drives the rotating shaft 11 to rotate, thereby driving the push rods 12 located in the drying cylinder 1 to rotate, and cooperates with the subsequent spraying of the adhesive to cause the powder to be formed into particles. Simultaneously, the second rotary motor 13 is started, and its output end drives a plurality of cutters to rotate, cutting the long strips of composite material in the initial forming process into small pieces to be formed into spherical particles during the rotation process. In addition, during the powder forming process, the exhaust fan 15 is started, which draws the powder still floating in the drying cylinder 1 during the particle forming process into the dust collector 17 through the air pipe 16 for separation and recovery.

[0067] The spraying of adhesive to promote powder molding, the rotation of the cutter to cut the composite, and the separation by the dust collector 17 are all existing technologies and will not be described in detail here.

[0068] In the description of the embodiments of the present invention, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0069] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, terms such as "first", "second" and other numerical terms do not imply an order or sequence when used herein unless expressly indicated above. Therefore, without departing from the teachings of the example embodiments, the first element, component, region, layer or section discussed above may be referred to as a second element, component, region, layer or section.

[0070] Spatially relative terms, such as "inside," "outside," "below," "beneath," "down," "above," "on," etc., may be used herein to describe the relationship of one element or feature to another element or feature as illustrated in the figures. In addition to the orientations depicted in the figures, spatially relative terms may be intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as being "below" or "below" other elements or features will be oriented to be "above" the other elements or features. Thus, the example term "below" may encompass both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0071] In the above discussion, unless otherwise indicated, the terms "about," "approximately," "substantially," etc., when used to describe a numerical value, mean a variation of + / - 10% of the value.

[0072] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
