Description

Technical Field

[0001] This utility model belongs to the field of connector technology, specifically relating to pipe fittings, and more particularly to a docking system and docking mechanism for a triple eccentric mixer. Background Technology

[0002] The triple eccentric mixer is a specially designed industrial mixing equipment. Its core feature is that it uses a triple eccentric structure (i.e., three eccentric devices with different axes) to achieve efficient and uniform mixing.

[0003] The mixing tank of the triple eccentric mixer has a feed pipe. When feeding is required, the feed pipe is turned upward to receive the material discharged from the discharge bin. When the mixing is completed and discharge is required, the feed pipe is turned downward to discharge the mixed material into the collection bin.

[0004] In related technologies, because the mixing tank needs to rotate, the feed pipe needs to maintain a certain distance when it rotates to the discharge hopper or collection hopper. This makes it easy for dust to escape when the feed pipe receives or discharges powdery materials.

[0005] Therefore, how to solve the above problems is a problem that urgently needs to be solved by those skilled in the art.

[0006] 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

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

Furthermore, in the figures, the thickness of parts may be exaggerated or reduced for the purpose of effectively depicting the technical content.

[0038] 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.

[0039] like Figure 1As shown, at least one embodiment provides a docking system for a triple eccentric mixer, comprising: a feed pipe 1 located on the mixing tank 4 of the triple eccentric mixer; an upper docking mechanism 2 connected to a first guide pipe 51 at the bottom of the discharge bin 5; and a lower docking mechanism 3 connected to a second guide pipe 61 at the top of the collection bin 6. Both the upper docking mechanism 2 and the lower docking mechanism 3 include: a sliding sleeve 21, with at least one first airbag assembly 23 disposed on the upper inner wall of the sliding sleeve 21, and at least one second airbag assembly 24 disposed on the lower side wall of the sliding sleeve 21; and at least two actuators 22, both used to connect the sliding sleeve 21 and a fixed position. The actuators 22 are adapted to drive the sliding sleeve 21 to rise and fall to insert into the feed pipe 1 or to be sleeved around the feed pipe 1, and the first airbag assembly 23 and the second airbag assembly 24 are both adapted to be sealed by expansion.

[0040] In this embodiment, the upper docking mechanism 2 and the lower docking mechanism 3 are floated. When it is necessary to connect with the feed pipe 1, they are inserted or sleeved with the feed pipe 1 by lifting and moving. Then, the expansion of the first airbag assembly 23 and the second airbag assembly 24 is used to seal it. This not only avoids affecting the rotation and mixing of the mixing tank 4 when not in use, but also prevents dust from escaping during discharge.

[0041] like Figure 2 As shown, in some embodiments, in the upper docking mechanism 2, the fixed position is located on the side wall of the sliding sleeve 21; wherein the driver 22 is disposed on the side wall of the sliding sleeve 21, and the driving end is connected to the side wall of the discharge bin 5 through the floating joint 25.

[0042] In this embodiment, the fixed position is the position that will not move; the driver 22 is set on the side wall of the sliding sleeve 21 so that the center of gravity falls on the sliding sleeve 21, thereby reducing the swaying of the sliding sleeve 21 during the lifting and lowering process.

[0043] like Figure 3 As shown, in some embodiments, in the lower docking mechanism 3, the fixed position is located on the side wall of the second guide tube 61; wherein the driver 22 is disposed on the side wall of the second guide tube 61, and the driving end is connected to the side wall of the sliding sleeve 21 through the floating joint 25.

[0044] In this embodiment, the driver 22 is mounted on the side wall of the second guide tube 61, which reduces the weight on the driver 22. That is, the driver 22 only needs to drive the lighter sliding sleeve 21 to rise and fall, thus reducing the load on the driver 22.

[0045] In some embodiments, the actuator 22 may be, but is not limited to, a cylinder.

[0046] like Figure 2 , Figure 4As shown, in some embodiments, in the upper docking mechanism 2, the inner diameter of the first airbag assembly 23 is larger than the outer diameter of the first guide tube 51, and the outer diameter of the second airbag assembly 24 is smaller than the inner diameter of the feed tube 1.

[0047] like Figure 3 , Figure 5 As shown, in some embodiments, in the lower docking mechanism 3, the inner diameter of the first airbag assembly 23 is larger than the outer diameter of the feed pipe 1, and the outer diameter of the second airbag assembly 24 is smaller than the inner diameter of the second guide pipe 61.

[0048] In this embodiment, since the mixing tank 4 needs to rotate and the overall equipment is large, the coaxiality between the sliding sleeve 21 and the feed pipe 1 is poor. Therefore, the difference in pipe diameter is used to facilitate the insertion or fitting of the sliding sleeve 21 and the feed pipe 1.

[0049] like Figure 6 , Figure 7 As shown, in some embodiments, the first airbag assembly 23 and the second airbag assembly 24 both include: a mounting ring 231, disposed on the side wall or inner wall of the sliding sleeve 21, and a mounting groove 232 is provided on the side wall or inner wall of the mounting ring 231; an airbag ring 233, disposed in the mounting groove 232 and connected to an air source; wherein, the airbag ring 233 is adapted to abut against the feed pipe 1 or the corresponding guide pipe by expansion.

[0050] In this embodiment, when the airbag ring 233 is not inflated, there is a gap between the mounting ring 231 and the feed pipe 1 or the corresponding guide pipe, which facilitates insertion, sleeve or movement; when the airbag ring 233 is inflated, the airbag ring 233 protrudes from the mounting groove 232, thereby sealing the gap.

[0051] like Figure 2 As shown, in some embodiments, the side wall of the sliding sleeve 21 is provided with an air outlet pipe 211; wherein a filter element 212 is provided at the opening of the air outlet pipe 211.

[0052] In this embodiment, an air outlet pipe 211 is provided to facilitate the falling of materials; at the same time, a filter element 212 is provided to prevent dust from escaping.

[0053] At least one embodiment also provides a docking mechanism for a triple-eccentric mixer, comprising: a sliding sleeve 21, at least one first airbag assembly 23 on the upper inner wall of the sliding sleeve 21, at least one second airbag assembly 24 on the lower side wall of the sliding sleeve 21; at least two actuators 22, both for connecting the sliding sleeve 21 and a fixed position; wherein the actuators 22 are adapted to drive the sliding sleeve 21 to rise and fall to insert into the feed pipe 1 or to be sleeved around the feed pipe 1, and the first airbag assembly 23 and the second airbag assembly 24 are both adapted to be sealed by expansion.

[0054] In this embodiment, the docking mechanism is set as a floating structure. When it is necessary to connect with the feed pipe 1, it is inserted or sleeved with the feed pipe 1 by lifting and moving. Then, it is sealed by the expansion of the first airbag assembly 23 and the second airbag assembly 24. This not only does not affect the rotation and mixing of the mixing tank 4, but also prevents dust from escaping during discharge.

[0055] In some embodiments, in the upper docking mechanism 2, the fixed position is located on the side wall of the sliding sleeve 21; wherein the driver 22 is disposed on the side wall of the sliding sleeve 21, and the driving end is connected to the side wall of the discharge bin 5 through the floating joint 25.

[0056] In this embodiment, the driver 22 is disposed on the side wall of the sliding sleeve 21, so that the center of gravity falls on the sliding sleeve 21, thereby reducing the swaying of the sliding sleeve 21 during the lifting and lowering process.

[0057] In the lower docking mechanism 3, the fixed position is located on the side wall of the second guide tube 61; wherein the driver 22 is disposed on the side wall of the second guide tube 61, and the driving end is connected to the side wall of the sliding sleeve 21 through the floating joint 25.

[0058] In this embodiment, the driver 22 is mounted on the side wall of the second guide tube 61, which reduces the weight on the driver 22. That is, the driver 22 only needs to drive the lighter sliding sleeve 21 to rise and fall, thus reducing the load on the driver 22.

[0059] In some embodiments, the first airbag assembly 23 and the second airbag assembly 24 each include: a mounting ring 231 disposed on the side wall or inner wall of the sliding sleeve 21, wherein a mounting groove 232 is formed on the inner wall or side wall of the mounting ring 231; and an airbag ring 233 disposed in the mounting groove 232 and connected to an air source; wherein the airbag ring 233 is adapted to abut against the feed pipe 1 or the corresponding guide pipe by expansion.

[0060] In this embodiment, when the airbag ring 233 is not inflated, there is a gap between the mounting ring 231 and the feed pipe 1 or the corresponding guide pipe, which facilitates insertion, sleeve or movement; when the airbag ring 233 is inflated, the airbag ring 233 protrudes from the mounting groove 232, thereby sealing the gap.

[0061] In summary, the docking system and docking mechanism of this triple eccentric mixer float the upper docking mechanism 2 and the lower docking mechanism 3. When it is necessary to connect with the feed pipe 1, the upper docking mechanism 2 and the lower docking mechanism 3 are inserted or sleeved with the feed pipe 1 by lifting and moving. Then, the first airbag assembly 23 and the second airbag assembly 24 are expanded to seal the connection. This not only does not affect the rotation and mixing of the mixing tank 4, but also prevents dust from escaping during discharge.

[0062] In this document, when it is said that the first component is located on the second component, this can mean that the first component can be directly formed on the second component, or that the third component can be inserted between the first component and the second component.

[0063] In this document, when an element or layer is referred to as “located,” “joined to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly located, joined, connected, attached to, or coupled to the other element or layer, or there may be intermediate elements or layers present.

Other terms used to describe relationships 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 related listed items.

[0064] In this document, exemplary 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…” modify the entire list of elements when following a list of elements, rather than 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.

[0065] The terminology used herein is for the purpose of describing specific exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may also be intended to include plural forms unless otherwise clearly stated herein. The terms “comprising,” “including,” and “having” are inclusive and thus specify the presence of features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein should not be construed as requiring them to be performed in the specific order discussed or shown, unless specifically identified as such.

[0066] As used herein, the phrases “in one embodiment,” “according to one embodiment,” “in some embodiments,” etc., generally refer to the fact that a particular feature, structure, or characteristic following the phrase can be included in at least one embodiment of this disclosure. Therefore, a particular feature, structure, or characteristic can be included in more than one embodiment of this disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms “example,” “exemplary,” etc., are used to “serve as an example, instance, or illustration.” Any implementation, aspect, or design described herein as “example” or “exemplary” is not necessarily to be construed as preferred or superior to other implementations, aspects, or designs. Rather, the use of the terms “example,” “exemplary,” etc., is intended to present concepts in a specific manner.

[0067] 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.

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.

[0070] 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.

[0071] 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.
