Description

Technical Field

[0001] This utility model relates to the field of material processing equipment technology, and in particular to a granulation bin and a swing granulator. Background Technology

[0002] A gyratory pellet mill is a device that applies shearing and extrusion forces to materials, breaking them down, reshaping them, and then passing them through a screen to reshape them. It is mainly used for granulating wet materials. Gyratory pellet mills are divided into single-drum and double-drum structures, with the double-drum structure meeting higher production efficiency requirements. Existing gyratory pellet mills use a screen winding shaft on the outer sides of the two drums and a support shaft in the middle of the drums. The screen is tightly wound by the outer winding shafts, ensuring it adheres closely to the screen positioning mechanism and is in close contact with the drums.

[0003] The problem is that when the drum diameter is large, under the same screen tension, due to the elasticity of the screen itself, the two drums rotate asynchronously, and the screen will "saw" back and forth on the middle support shaft. This phenomenon will greatly reduce the service life of the screen, leading to frequent shutdowns to replace the screen, thereby reducing production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a granulation bin and a gyratory granulator to solve, to a certain extent, the technical problem of the screen reciprocating "sawing" on the middle support shaft in the prior art, which greatly reduces the service life of the screen, leading to frequent shutdowns to replace the screen and thus reducing production efficiency.

[0005] This utility model provides a granulation bin, comprising: a bin body; rollers, at least two rollers, each roller being rotatably mounted on the bin body; a wire mesh roller, rotatably mounted on the bin body, with a wire mesh roller on both sides of each roller, and two adjacent wire mesh rollers between adjacent rollers; and a screen, at least two screens, with multiple screens corresponding one-to-one with multiple rollers; for the same roller, one side of the screen is fixedly connected to a wire mesh roller on one side, and the other side passes under the roller and is fixedly connected to a wire mesh roller on the other side.

[0006] Each roller has a winding shaft on both sides, and two adjacent winding shafts are arranged between two adjacent rollers. Each roller corresponds to one screen. One side of the screen is fixedly connected to the winding shaft on one side of the roller, and the other side of the screen is fixedly connected to the winding shaft on the other side of the roller. That is, the winding shafts corresponding to the two adjacent rollers are independent of each other, and the winding shafts corresponding to the two screens are also independent of each other. A pair of winding shafts can tighten the corresponding screen, which avoids tensioning difficulties caused by excessively long screens and avoids the "sawing" phenomenon that occurs when two screens share a single winding shaft. This improves the service life of the screens, reduces the number of downtimes for screen replacement, and thus improves production efficiency. In addition, the tension of each screen can be adjusted independently without interference, which facilitates the adjustment of screens with problems; it also allows for the replacement of a single screen, saving screens to a certain extent and reducing production costs.

[0007] Furthermore, for the same roller, the winding shaft on the first side is a first winding shaft, and the winding shaft on the second side is a second winding shaft; the pelleting bin further includes: a first positioning component, which is disposed on the bin body to limit the position of the first winding shaft; and a second positioning component, which is disposed on the bin body to limit the position of the second winding shaft.

[0008] Furthermore, the first positioning component includes: a first pawl, which is rotatably mounted on the housing; a first ratchet, which is fixedly connected to the first winding shaft; and the first pawl engaging with the first ratchet.

[0009] Furthermore, the second positioning component includes: a second pawl, which is rotatably mounted on the housing; a second ratchet, which is fixedly connected to the second winding shaft; and the second pawl engaging with the second ratchet.

[0010] Furthermore, in two adjacent rollers, the second roll of the first roller and the first roll of the second roller are arranged adjacent to each other, and correspondingly, the second pawl of the first roller and the first pawl of the second roller are arranged adjacent to each other; the adjacent first pawl and second pawl are rotatably mounted on the bin body via a rotating shaft.

[0011] Furthermore, the pelleting bin also includes a material distribution cover, which is disposed on the bin body and located above two adjacently arranged wire mesh rollers to cover the gap between the two adjacently arranged wire mesh rollers.

[0012] Furthermore, the material distribution cover is detachably connected to the hopper body.

[0013] Furthermore, a support frame is fixed on the silo body, and the material distribution cover is attached to the support frame.

[0014] Furthermore, the silo body includes two oppositely arranged side walls, and the two side walls are provided with support holes; the screen winding shaft includes a support cylinder and a main shaft rotatably disposed within the support cylinder; both ends of the support cylinder are respectively inserted and fixed within the two support holes; the support cylinder is provided with a screen thread extending axially along the main shaft, and one side of the screen passes through the screen thread and is fixedly connected to the main shaft; at least one of the support holes is provided with an anti-closing boss, and the anti-closing boss is engaged within the screen thread.

[0015] This utility model also provides a gyratory granulator, comprising: a power unit and the aforementioned gyratory granulator, wherein the power unit is connected to the roller drive.

Detailed Implementation

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0024] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0025] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] 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 the orientation or positional relationship, are based on the orientation or positional relationship 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, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 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.

[0028] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0029] like Figures 1 to 4 As shown, this utility model provides a granulation bin 1, including: a bin body 101; rollers, the number of rollers being at least two, each roller being rotatably mounted on the bin body 101; a wire mesh roller, rotatably mounted on the bin body 101, with a wire mesh roller on both sides of each roller, and two adjacent wire mesh rollers between adjacent rollers; a screen 104, the number of screens 104 being at least two, with multiple screens 104 corresponding to multiple rollers; for the same roller, one side of the screen 104 is fixedly connected to a wire mesh roller on one side, and the other side passes under the roller and is fixedly connected to a wire mesh roller on the other side.

[0030] In this embodiment, each roller has a winding shaft on both sides, and two adjacent winding shafts are arranged between two adjacent rollers. That is, one roller corresponds to one pair of winding shafts, and the two pairs of winding shafts are relatively independent. Each roller corresponds to one screen 104. One side of the screen 104 is fixedly connected to the winding shaft on one side of the roller, and the other side of the screen 104 is fixedly connected to the winding shaft on the other side of the roller. In other words, in two adjacent rollers, the winding shafts corresponding to the two rollers are independent of each other, and the winding shafts corresponding to the two screens 104 are independent of each other. One pair of winding shafts can tighten the corresponding screen 104, which avoids the tensioning difficulties that occur when the screen 104 is too long, and avoids the "sawing" phenomenon that occurs when two screens 104 share one winding shaft, thereby improving the service life of the screen 104, reducing the number of times the machine stops to replace the screen 104, and thus improving production efficiency. In addition, the tension of each screen 104 can be adjusted independently without interfering with each other, which makes it convenient to adjust the screen 104 with problems; it also allows for the replacement of a particular screen 104, saving screens 104 to a certain extent and reducing production costs.

[0031] The number of rollers can be set as needed, for example: Figure 1 and Figure 2 As shown, there are two rollers, which are arranged side by side.

[0032] Understandably, a screen positioning mechanism 117 can be installed on the drum to position the screen 104.

[0033] like Figure 1 and Figure 3As shown, based on the above embodiments, further, for the same roller, the first side of the winding shaft is the first winding shaft 105, and the second side of the winding shaft is the second winding shaft 106; the granulation chamber 1 also includes: a first positioning component, which is disposed on the chamber body 101 to limit the position of the first winding shaft 105; and a second positioning component, which is disposed on the chamber body 101 to limit the position of the second winding shaft 106.

[0034] In this embodiment, the first positioning component can limit the position of the first roll of mesh 105, and the second positioning component can limit the position of the second roll of mesh 106, so as to maintain the state of the screen 104 after the tension is adjusted.

[0035] The first positioning component can have various structural forms. For example, the first positioning component includes a positioning rod, a positioning plate, and fasteners. The positioning rod is fixed on the cabin body and has positioning holes. The positioning plate is coaxially fixed on the first roll of netting 105. Along the circumferential direction of the positioning plate, the positioning plate has multiple adjustment holes spaced apart. The position of the first roll of netting 105 is fixed by passing the fasteners through the positioning holes and the corresponding adjustment holes.

[0036] The second positioning component can have various structural forms. For example, the second positioning component includes a positioning block and an adjusting sleeve. The positioning block is fixed on the chamber body 101, and the adjusting sleeve is coaxially fixed on the second winding shaft 106. A positioning magnet is fixed on the positioning block, and multiple mating magnets are spaced apart on the adjusting sleeve along the circumferential direction. The positioning magnet can be attracted and fixed with a mating magnet.

[0037] The first positioning component and the second positioning component can adopt the same structural form or different structural forms.

[0038] As an alternative, such as Figure 1 As shown, the first positioning component includes: a first pawl 107, which is rotatably mounted on the housing 101; a first ratchet 108, which is fixedly connected to the first winding shaft 105; and the first pawl 107 meshing with the first ratchet 108.

[0039] In this embodiment, the first pawl 107 can rotate in one direction but cannot rotate in the opposite direction. Through the cooperation of the first pawl 107 and the first ratchet 108, the position of the first roll spool 105 can be fixed. This first positioning component has a simple structure and is easy to operate.

[0040] As an alternative, such as Figure 1As shown, the second positioning component includes: a second pawl 109, which is rotatably mounted on the housing 101; a second ratchet 110, which is fixedly connected to the second winding shaft 106; and the second pawl 109 meshing with the second ratchet 110.

[0041] In this embodiment, the second pawl 109 can rotate in two directions but cannot rotate in the opposite direction. Through the cooperation of the second pawl 109 and the second ratchet 110, the position of the second roll shaft 106 can be fixed. This type of second positioning component has a simple structure and is easy to operate.

[0042] It is understandable that in two adjacent rollers, the second roll of the web 106 of the first roller 102 and the first roll of the web 105 of the second roller 103 are arranged adjacent to each other, and correspondingly, the second pawl 109 of the first roller and the first pawl 107 of the second roller are arranged adjacent to each other.

[0043] Specifically, for the adjacent first pawl 107 and second pawl 109, two rotating shafts can be fixed on the housing 101. The two rotating shafts are rotatably connected to the first pawl 107 and the second pawl 109 respectively, thereby realizing the rotation of the first pawl 107 and the second pawl 109.

[0044] As an alternative, such as Figure 1 As shown, there is one rotating shaft, which is defined as the intermediate shaft 111. The intermediate shaft 111 is fixedly installed on the housing 101. The first pawl 107 and the second pawl 109, which are arranged adjacently, are rotatably connected to the intermediate shaft 111.

[0045] In this embodiment, the first pawl 107 and the second pawl 109, which are arranged adjacent to each other, share a common intermediate shaft 111, which can save installation space, make the granulation chamber 1 compact, reduce the volume of the granulation chamber, reduce the number of parts, and facilitate installation.

[0046] like Figure 4 As shown, based on any of the above embodiments, the pelleting chamber 1 further includes a material distribution cover 112, which is disposed on the chamber body 101 and located above two adjacently arranged wire mesh rollers to cover the gap between the two adjacently arranged wire mesh rollers.

[0047] In this embodiment, the material distribution cover 112 can block the gap between two adjacent winding shafts, thus preventing materials from entering between the two adjacent rollers and reducing cleaning work.

[0048] The material distribution cover 112 can be fixed to the hopper body 101 in a non-removable manner.

[0049] As an optional solution, the material distribution cover 112 is detachably connected to the bin body 101, so that when replacing the screen 104, the screen roller can be operated from the top, which reduces the labor intensity of the operator, and also reduces dead corners, making it easier to clean.

[0050] The material distribution cover 112 can be detachably connected to the cabin body via threaded connection or snap-fit.

[0051] As an alternative, such as Figure 4 As shown, a bracket 113 is fixed on the silo body 101, and the material distribution cover 112 is attached to the bracket 113 to facilitate the installation of the material distribution cover 112.

[0052] Specifically, the material distribution cover 112 is inverted "V" shape, which facilitates the downward movement of materials and prevents materials from lingering on the material distribution cover 112.

[0053] like Figure 3 As shown, based on any of the above embodiments, the silo body 101 further includes two oppositely arranged side walls, and the two side walls are provided with support holes 114; the winding shaft includes a support cylinder 115 and a main shaft 118 rotatably disposed in the support cylinder 115; the two ends of the support cylinder 115 are respectively inserted and fixed in the two support holes 114; the support cylinder 115 is provided with a mesh-passing slit extending axially along the main shaft 118, and one side of the screen 104 passes through the mesh-passing slit and is fixedly connected to the main shaft 118; at least one support hole 114 is provided with an anti-closing boss 116 (it can be an anti-closing boss 116 in one support hole 114, or it can be an anti-closing boss 116 in both support holes 114), and the anti-closing boss 116 is engaged in the mesh-passing slit.

[0054] In this embodiment, the shaft rotates, thereby winding the screen 104 into the support cylinder 115 through the mesh seam. The support hole 114 is provided with an anti-closing boss 116, which can prevent the mesh seam from closing. This prevents the mesh seam from closing when the shaft is winding the screen 104, causing inconsistent tension of the screen 104 along the axial direction of the shaft, and increasing the risk of the shaft slipping during production.

[0055] An embodiment of this utility model also provides a gyratory granulator, including the granulation chamber 1 of any of the above-described technical solutions, and further including a power unit 2, which is connected to a roller drive. Therefore, the gyratory granulation has all the beneficial technical effects of the granulation chamber 1, which will not be elaborated here.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model. Numerous specific details are set forth in the specification provided herein. However, it is understood that embodiments of this utility model can be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification. Furthermore, those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are meant to be within the scope of this utility model and form different embodiments.
