[0046] Before explaining in detail any implementation manner of the present application, it should be understood that the present application is not limited to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0047] In the present application, the terms "comprise", "include", "have" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising a..." does not exclude the presence of additional identical elements in the process, method, article or device comprising such element.

[0048] In the present application, the term "and / or" describes the relationship between associated objects and represents three possible relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in the present application generally represents an "and / or" relationship between the associated objects before and after.

[0049] In the present application, the terms "connect", "combine", "couple", "mount" can be direct connection, combination, coupling or mounting, or indirect connection, combination, coupling or mounting. Among them, by way of example, direct connection means that two parts or components are connected together without the need for an intermediate member, and indirect connection means that two parts or components are respectively connected to at least one intermediate member, and these two parts or components are connected through the intermediate member. In addition, "connect" and "couple" are not limited to physical or mechanical connection or coupling, and may include electrical connection or coupling.

[0050] In this application, those of ordinary skill in the art will understand that relative terms used in connection with quantities or conditions (e.g., "about", "approximately", "substantially", etc.) are intended to include the stated value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances resulting from manufacturing, assembly, use in relation to a particular value, etc. Such terms should also be considered to disclose ranges defined by the absolute values of two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values without the use of relative terms should also be disclosed as specific values with tolerances. Additionally, "substantially" when expressing relative angular positional relationships (e.g., substantially parallel, substantially perpendicular) may refer to plus or minus a certain number of degrees (e.g., 1 degree, 5 degrees, 10 degrees or more) from the indicated angle.

[0051] In this application, those of ordinary skill in the art will understand that the functions performed by components can be performed by one component, multiple components, one part, or multiple parts. Similarly, the functions performed by parts can also be performed by one part, one component, or a combination of multiple parts.

[0052] In this application, the orientation terms such as "upper", "lower", "left", "right", "front", "rear", etc. are described based on the orientation and positional relationship shown in the drawings, and should not be construed as a limitation on the embodiments of this application. Additionally, in the context, it should also be understood that when it is mentioned that one element is connected "above" or "below" another element, it can not only be directly connected "above" or "below" another element, but also be indirectly connected "above" or "below" another element through an intermediate element. It should also be understood that orientation terms such as upper side, lower side, left side, right side, front side, rear side, etc. not only represent the positive orientation, but can also be understood as the side orientation. For example, below can include directly below, lower left, lower right, lower front, and lower rear, etc.

[0053] Figure 1 A cross-sectional schematic view of the dispenser provided by this application is shown. Figure 2 Shown is Figure 1 A partial schematic view of the dispenser in Figures 1 to 2As shown, the dispenser provided by the present application includes a housing assembly 1, an inner shaft assembly 2, and a seal 3. The housing assembly 1 has a receiving space extending along a first axis; a part of the inner shaft assembly 2 is located in the receiving space, and the inner shaft assembly 2 can rotate relative to the housing assembly 1 about the first axis; a plurality of seals 3 are provided between the inner shaft assembly 2 and the inner wall of the receiving space, and the plurality of seals 3 are spaced apart along the extending direction of the first axis. Among them, the housing assembly 1 includes at least two shells detachably and fixedly connected in sequence along the first axis, so that when the dispenser leaks, the seals 3 inside the dispenser can be quickly replaced, enabling the device to resume startup as soon as possible and ensuring the operating efficiency of the device.

[0054] The present application also provides a filling device, including a driving device and the above-mentioned dispenser. The driving device is used to drive the inner shaft assembly 2 to rotate relative to the housing assembly 1 about the first axis to ensure that the dispenser can work properly. It should be noted that the dispenser provided by the present application can be used in various filling devices such as tea, dairy products, fruit juices with pulp, and fruit juices with fibers. As a transition part between the fixed material pipeline and the rotating device, the dispenser enables the material to be smoothly transported from the non-rotating pipeline to the rotating device through this component.

[0055] In Figure 1 In the example, the number of shells is two. Specifically, the housing assembly 1 includes a first shell 11 and a second shell 12, and the second shell 12 is detachably fixed to the lower end of the first shell 11. The first shell 11 has a first receiving cavity extending along the first axis, and the second shell 12 has a second receiving cavity extending along the first axis. The second shell 12 is detachably fixed to one end of the first shell 11 and the second receiving cavity and the first receiving cavity cooperate to form a receiving space. There are a plurality of seals 3 spaced apart along the extending direction of the first axis between the inner wall of the first receiving cavity of the first shell 11 and the inner shaft assembly 2. There are a plurality of seals 3 spaced apart along the extending direction of the first axis between the inner wall of the second receiving cavity of the second shell 12 and the inner shaft assembly 2. When leakage occurs between the second shell 12 and the inner shaft assembly 2, only the second shell 12 needs to be disassembled and the seals 3 at the second shell 12 can be replaced without disassembling the first shell 11, so that the device can resume startup as soon as possible and ensure the operating efficiency of the device. When leakage occurs between the first shell 11 and the inner shaft assembly 2, both the first shell 11 and the second shell 12 need to be disassembled and the seals 3 at the corresponding positions need to be replaced.

[0056] In some other embodiments, the number of shells can also be three, four, five, or any other number, which can be specifically designed according to the overall length of the housing assembly 1 in the first axis direction and specific requirements, and will not be exemplified one by one here.

[0057] In Figure 1In the example, the number of seals 3 is eight. For convenience of description, the eight seals 3 are sequentially denoted as the first seal 3a, the second seal 3b, the third seal 3c, the fourth seal 3d, the fifth seal 3e, the sixth seal 3f, the seventh seal 3g, and the eighth seal 3h from bottom to top along the first axis. Among them, the third seal 3c and the eighth seal 3h are dust-proof rings, and the remaining seals 3 are rotary seals.

[0058] Continue to refer to Figure 1 As shown, the inner shaft assembly 2 includes a fixed sleeve 21 and a central shaft 22 detachably and fixedly connected to the fixed sleeve 21. The fixed sleeve 21 and the housing assembly 1 are rotationally engaged about the first axis. The central shaft 22 has a fluid flow channel 220 and a discharge port 2201 communicating with the fluid flow channel 220. The housing assembly 1 has a feed port 130 communicating with the fluid flow channel 220. The center lines of the feed port 130 and the discharge port 2201 coincide with the first axis, and the feed port 130 and the discharge port 2201 are arranged in the same direction, which can reduce the pressure loss of liquid transportation, reduce the foam generated by impact, reduce the vibration generated by impact, and is beneficial to the stable operation of the equipment.

[0059] In this embodiment, the central shaft 22 includes a shaft portion 221 and a connecting portion 222. The shaft portion 221 is located in the accommodation space, and the shaft portion 221 has a fluid flow channel 220 and the discharge port 2201. The connecting portion 222 is detachably and fixedly connected to the fixed sleeve 21. Such a setting can not only facilitate the rotational cooperation between the central shaft 22 and the housing assembly 1, but also facilitate the connection between the central shaft 22 and the fixed sleeve 21, improving the overall assembly efficiency of the distributor.

[0060] The fixed sleeve 21 includes a shaft sleeve portion 211 and a bearing accommodation portion 212 cooperating with the shaft sleeve portion 211. The shaft sleeve portion 211 is located in the accommodation space and is detachably and fixedly connected to the central shaft 22, and the shaft sleeve portion 211 has an installation space 2110 for the shaft portion 221 to pass through. The bearing accommodation portion 212 is located outside the accommodation space and a first bearing 6 is provided between the bearing accommodation portion 212 and the outer wall of the housing assembly 1. Such a setting can prevent liquid from flowing into the first bearing 6 by installing the first bearing 6 in the space formed between the bearing accommodation portion 212 and the housing assembly 1, thereby ensuring the normal operation of the first bearing 6 and extending the service life of the first bearing 6.

[0061] To limit the first bearing 6, the distributor further includes a bearing pressing plate 7. The bearing pressing plate 7 is detachably fixed to the bearing accommodation portion 212 and is used to limit the first bearing 6. Specifically, the bearing accommodation portion 212 has a limiting surface to limit the upper part of the first bearing 6, and the bearing pressing plate 7 is detachably fixed to the lower end of the bearing accommodation portion 212 by screws to limit the lower part of the first bearing 6.

[0062] Further, a second bearing 9 is provided between the junction of the first housing 11 and the second housing 12 and the shaft portion 221 of the central shaft 22. In other words, a first bearing 6 and a second bearing 9 are provided between the shaft portion 221 of the central shaft 22 and the housing assembly 1. The upper and lower double-bearing structure can make the rotation of the inner shaft assembly 2 more stable and reliable.

[0063] When the driving device drives the inner shaft assembly 2 to rotate relative to the housing assembly 1, due to the presence of the seal 3 between the inner shaft assembly 2 and the housing assembly 1, the frictional force between the inner shaft assembly 2 and the housing assembly 1 is relatively large. To prevent the housing assembly 1 from rotating synchronously with the inner shaft assembly 2, the housing assembly 1 is connected with an anti-rotation plate 8, and the anti-rotation plate 8 is used to connect with an external anti-rotation frame to limit the rotation of the housing assembly 1 with the inner shaft assembly 2.

[0064] Figure 3 The structural schematic diagram of the leak detection module 4 provided by the present application is shown. As Figure 3 Combined with Figure 1 and Figure 2 shown, in order to facilitate the monitoring of the liquid leakage situation of the dispenser, the dispenser further includes a leak detection module 4. The housing assembly 1 further has a leak detection channel 101 communicating with the accommodation space, and the leak detection module 4 is provided in the leak detection channel 101. The leak detection channel 101 includes an annular channel 1011 and a mounting channel 1012 communicating with the annular channel 1011. The annular channel 1011 is centered on the first axis, and the annular channel 1011 is directly communicated with the accommodation space. The mounting channel 1012 is used to mount the leak detection module 4. In addition, in one leak detection channel 101, the number of the mounting channels 1012 is at least two, and at least two mounting channels 1012 are arranged around the circumference of the annular channel 1011.

[0065] In Figure 1 and Figure 2In the example, the number of leak detection modules 4 is six. Correspondingly, the number of leak detection channels 101 is three, that is, each leak detection channel 101 has two installation channels 1012, and one leak detection module 4 is installed in each installation channel 1012. For the convenience of description, the three leak detection channels 101 are sequentially denoted as the first leak detection channel 101a, the second leak detection channel 101b, and the third leak detection channel 101c from bottom to top along the first axis. The six leak detection modules 4 are respectively denoted as the first leak detection module 4a, the second leak detection module 4b, the third leak detection module 4c, the fourth leak detection module 4d, the fifth leak detection module 4e, and the sixth leak detection module 4f. Among them, the first leak detection module 4a and the second leak detection module 4b are installed in the first leak detection channel 101a, the third leak detection module 4c and the fourth leak detection module 4d are installed in the second leak detection channel 101b, and the fifth leak detection module 4e and the sixth leak detection module 4f are installed in the third leak detection channel 101c. With such a setting, the leak conditions at various positions can be detected by each leak detection module 4, so as to facilitate the staff to replace the seal 3 at the corresponding area in time.

[0066] The leak detection module 4 includes an insulating sleeve 41 and a metal probe 42. The insulating sleeve 41 is in interference fit with the installation channel 1012, and one end of the metal probe 42 passes through the insulating sleeve 41 and is exposed in the installation channel 1012. Among them, the metal probe 42 is electrically connected to the positive pole of the power supply, and the housing assembly 1 is electrically connected to the negative pole of the power supply. The two are insulated and connected through the insulating sleeve 41. The insulating sleeve 41 can ensure the insulating connection between the metal probe 42 and the housing assembly 1 to ensure the detection accuracy of the metal probe 42. When each seal 3 is sealed well and there is no leakage in the dispenser, since the air in the insulating sleeve 41 and the leak detection channel 101 is not conductive, the circuit is in an open state and there is no current signal. When the dispenser leaks, liquid materials will enter the leak detection channel 101. Since the conductivity of general liquid materials is much higher than that of the insulating sleeve 41 and air, a certain current signal will be generated in the circuit. By monitoring the value of the current signal, it can be judged whether there is a leak.

[0067] The housing assembly 1 also has a leak observation hole 102 communicating with the accommodation space, and the liquid flowing from the accommodation space into the leak observation hole 102 can flow out from the outlet of the leak observation hole 102 under the action of gravity. The leak observation hole 102 includes an annular groove 1021 and a through hole 1022 communicating with the annular groove 1021. The annular groove 1021 is centered on the first axis, and the annular groove 1021 is directly communicated with the accommodation space. The extending direction of the through hole 1022 is set at an acute angle with the first axis, so that the liquid can flow out along the through hole 1022 under the action of its own gravity, facilitating the staff to monitor the working condition of the dispenser in time. When the leak detection module 4 fails, the staff can manually observe whether the dispenser leaks through the leak observation hole 102.

[0068] In this embodiment, the second bearing 9 is located below the leakage observation hole 102. A convex ring structure 10211 is provided in the annular groove 1021 of the leakage observation hole 102. The convex ring structure 10211 is used to prevent the liquid flowing into the leakage observation hole 102 from flowing into the second bearing 9 through the gap between the central shaft 22 and the second housing 12, thereby ensuring the stable operation of the second bearing 9 and extending the service life of the second bearing 9.

[0069] Figure 4 The steam flow schematic diagram of the dispenser provided by the present application is shown. Figure 5 Shown is Figure 4 a partial schematic diagram of the dispenser in Figures 4 to 5 and in combination with Figure 1 As shown, a part of the inner shaft assembly 2 is located in the accommodation space and has a rotational clearance between the inner wall of the accommodation space. The outer housing assembly 1 further has a steam channel 103 communicating with the rotational clearance. A plurality of steam channels 103 are arranged at intervals along the first axis; each steam channel 103 includes an annular communication part 1031, an inlet channel 1032, and an outlet channel 1033. The annular communication part 1031 is directly communicated with the rotational clearance, and both the inlet channel 1032 and the outlet channel 1033 are communicated with the annular communication part 1031; the plurality of steam channels 103 are connected in series in sequence, and the inlet channel 1032 of one steam channel 103 in two adjacent steam channels 103 is communicated with the outlet channel 1033 of the other steam channel 103. The inlet channel 1032 in the open state is used for allowing external steam to flow into the rotational clearance, and the outlet channel 1033 in the open state is used for allowing the steam in the rotational clearance to flow out. By supplying steam to the inlet channel 1032 of the steam channel 103, the steam flows in the rotational clearance between the inner shaft assembly 2 and the outer housing assembly 1, so that a steam area can be formed in the rotational clearance on the outer peripheral side of the liquid flow area (usually a sterile area) of the dispenser, and the steam is used to perform steam sterilization on the air in the rotational clearance, ensuring the sterile environment of the sterile area and improving the sterile safety of the equipment.

[0070] In addition, the dispenser further includes a steam joint 5, and steam joints 5 are provided on both the inlet channel 1032 and the outlet channel 1033 of each steam channel 103. By providing the steam joint 5, it is convenient to connect the steam channels 103 through pipelines, improving the assembly efficiency of the equipment. For example, along the first axis direction, the connection between two adjacent steam joints 5 can be quickly connected by a hose quick-insert method.

[0071] In Figure 4In the example, the number of steam channels 103 is three, and each steam channel 103 has an inlet channel 1032 and an outlet channel 1033. For the convenience of description, the three steam channels 103 are sequentially denoted as the first steam channel 103a, the second steam channel 103b, and the third steam channel 103c from bottom to top along the first axis. The inlet channel 1032 of the first steam channel 103a is connected to the first steam joint 5a, and its outlet channel 1033 is connected to the second steam joint 5b; the inlet channel 1032 of the second steam channel 103b is connected to the third steam joint 5c, and its outlet channel 1033 is connected to the fourth steam joint 5d; the inlet channel 1032 of the third steam channel 103c is connected to the fifth steam joint 5e, and its outlet channel 1033 is connected to the sixth steam joint 5f. In practical applications, the steam outlet of an external steam supply device is communicated with the first steam joint 5a, the second steam joint 5b is communicated with the third steam joint 5c through a pipeline, the fourth steam joint 5d is communicated with the fifth steam joint 5e through a pipeline, and the sixth steam joint 5f is communicated with the inlet of the external steam supply device through a pipeline to realize the recycling of steam.

[0072] It can be understood that high-temperature steam can kill most bacteria, improve the aseptic safety of the equipment, and in production, in case of slight leakage of the seal, the existence of a steam protection barrier can minimize the risk of aseptic loss.

[0073] A plurality of seals 3 are arranged at intervals along the extending direction of the first axis, and the steam channel 103 is located between two adjacent seals 3, and the sealing performance on both sides of the steam channel 103 avoids steam leakage and ensures the sterilization effect of steam.

[0074] Figure 6 The liquid flow schematic diagram of the dispenser provided by the present application is shown. As Figure 6 Combined with Figure 1As shown, a first cleaning chamber 20a is formed by the cooperation between the outer wall of the shaft portion 221 and the inner wall of the installation space 2110. The shaft sleeve portion 211 has a first return port 201 communicating with the first cleaning chamber 20a. The outer wall of the shaft portion 221 and the inner wall of the accommodation space cooperate to form a second cleaning chamber 20b communicating with the first cleaning chamber 20a.
