Description

Technical Field

[0001] The present invention relates to an adapter plate for connecting a spinning pump device and a pipeline for conveying spinning fluid for synthetic fibers, and to a related spinning pump system using the adapter plate. Background Technology

[0002] High-precision spinning pump devices are commonly used in the production of synthetic fibers and filaments such as spandex fibers. These spinning pump devices are mounted on an adapter plate for both connecting the spinning pump device and for connecting the delivery pipeline. For example, external gear pumps, as described in DE102016013684A1 and constructed based on the planetary gear pump principle, are particularly used in spinning pump devices.

[0003] The driving and driven gears of the planetary gear pump are connected to the drive source, which drives the planetary gears located on the outer periphery of the power source through meshing.

[0004] The spinning fluid from the supply line is then conveyed to an adapter plate formed by the meshing recess of the external gear and the driving gear. This adapter plate has multiple attachments that allow the supply line to be connected to its respective spinning nozzle.

[0005] The number of external gears determines the number of pipelines that can be supplied. Thus, for example, with eight planetary gears, eight pipelines can be supplied. In this case, the adapter board must be equipped with a corresponding number of accessories.

[0006] This type of planetary gear pump can also be arranged in series. Currently, adapter plates with up to 40 accessories are available.

[0007] However, the above methods have limitations in terms of technology and space.

[0008] The more accessories that need to be accommodated in the adapter plate, the larger the perimeter and thickness of the adapter plate must be. Furthermore, the increased number of accessories complicates the assembly and disassembly of pipeline connections.

[0009] Increasing pump output using an additional spinning pump unit with existing adapter boards is only laborious and feasible, as the oversized adapter boards are difficult to move and set up. Summary of the Invention

[0010] Therefore, the object of the present invention is to provide an adapter plate and a pump system having the adapter plate, which is easy to maintain and, despite this, allows for increased pump output through additional piping without additional space.

[0011] Regarding the adapter board, according to the present invention, this objective is achieved by an adapter board.

[0012] The adapter plate according to the invention can be equipped with pump devices on both sides and provide additional connection areas for multiple pipelines for conveying spinning fluid for synthetic fibers.

[0014] Using the adapter plate according to the invention, the spinning pump unit can be replaced more easily. There is no need to remove the tubing connected to the accessories when replacing the spinning pump unit. Furthermore, the spinning pump units can be replaced independently of each other.

[0015] According to an improved version of the adapter plate, the adapter plate on the first connection side in the pipeline connection has multiple attachments that surround at least partially around the first and / or second spinning pump connection in a ring-like manner.

[0016] The attachments in this document are understood to be preferably threaded connection components, which are suitable for assembling rigid tubing and / or flexible tubing in a fluid-tight manner.

[0017] Individual pipelines can be connected and disconnected in a trouble-free manner via threads. Threaded accessories can be created via threads for form-fit and force-fit connections to adapter plates for fluid sealing.

[0018] According to an improved version of the adapter plate, multiple accessories extend substantially parallel to the rotation axis of the spinning pump device.

[0019] According to another improvement of the adapter plate of the present invention, the adapter plate is configured to have conduits for supplying and discharging the spinning fluid to be conveyed.

[0020] According to another improvement of the adapter plate of the present invention, the adapter plate is provided with a through hole for accommodating at least one drive shaft of the first and / or second spinning pump device.

[0021] According to another improved version of the adapter plate, the drive shaft connecting sleeve is disposed in the through hole.

[0022] According to another improved embodiment of the adapter plate of the present invention, the first spinning pump device can be directly driven by the drive shaft of the spinning pump drive device, and the second spinning pump device can be indirectly driven by the drive shaft of the first spinning pump device.

[0023] In another improved embodiment of the adapter plate of the present invention, the first connection side is defined by the sub-adapter plate, wherein at least one pipeline connection portion and an accessory for connecting to the pipeline in a fluid-tight manner are provided.

[0024] According to another improved embodiment of the adapter plate of the present invention, the adapter plate is composed of a first sub-adapter plate and a second sub-adapter plate, wherein the first sub-adapter plate and the second sub-adapter plate are both configured in a complementary manner and, in the assembled state, form a conduit groove and a conduit hole for distributing the spinning fluid to be conveyed (towards and away from their respective spinning pump devices), wherein a spinning pump connection portion for fluid-tightly connecting to the second spinning pump device is configured in the second sub-adapter plate.

[0025] According to another improvement of the adapter plate of the present invention, the first and / or second spinning device has a plurality of external gear pump plates arranged in series, wherein each external gear pump plate has at least one driven external gear and a master-driven external gear, wherein the master-driven gear and the driven gear are connected to the associated external gear pump plate, and wherein the number of the plurality of accessories approximately corresponds to the number of driven gears in the first and / or second spinning pump device.

[0026] In this article, the driven gear is understood, for example, as an external gear that meshes with the driving and driven external gears in a meshing manner.

[0027] According to another improvement of the adapter plate of the present invention, the spinning pump device has a plurality of external gear pump plates arranged in series, wherein each external gear pump plate has at least one driven external gear and a master-driven external gear, wherein the master-driven gear and the driven gear are in circulation connection with the associated external gear pump plate, wherein the number of the plurality of accessories in the first and / or second adapter plates approximately corresponds to the number of driven gears in the first and / or second spinning pump device.

[0028] In this article, flow connection is understood as a connection between the relevant meshing areas of gears, which allows fluid to be delivered to an accessory via a series-connected external gear pump plate, for example by forming corresponding recesses in the delivery line in the spinning pump device and the adapter plate.

[0029] Regarding the spinning pump system, this objective is achieved according to the present invention via a spinning pump system.

[0030] According to another aspect of the present invention, a spinning pump system for conveying spinning fluid for synthetic fibers is provided, wherein the spinning pump system comprises:

[0031] - A spinning pump drive unit for driving one of the drive shafts of the first and / or second spinning pump unit;

[0042] Figure 1 A spinning pump system 1 having an adapter plate 5 according to the invention is shown in a first perspective view. Detailed Implementation

[0043] The spinning pump system 1 has a spinning pump drive device 2, a shaft connector 3, a second adapter plate 6 having a second spinning pump device 4.2, and an adapter plate 5. The adapter plate is fluid-sealed to the second adapter plate 6, the first spinning pump device 4.1, and the second spinning pump device 4.2 on a first connection side 51 and a second connection side 53.

[0044] Figure 2 Shown in another 3D view Figure 1 The spinning pump system 1, wherein a threaded connection mechanism 8 is shown herein, thereby allowing the spinning pump device 4 and the adapter plate 5 and the second adapter plate 6 to be detachably connected to each other.

[0045] If possible Figure 1 and Figure 2 As can be seen, the spinning pump drive unit 2 has an electric drive unit 21 including a gearbox 22 and a shaft connector 3.

[0046] The drive shaft 20 of the spinning pump drive device 2 is connected to the drive shafts 30 and 31 of the first spinning pump device 4.1 or the second spinning pump device 4.2 respectively via the shaft connector 3.

[0047] If possible Figure 3 As seen in the image, starting from the electric drive unit 21, the spinning pump unit 4, the adapter plate 5, the second adapter plate 6, and the spinning pump drive unit 2 are arranged in the following order.

[0048] The electric drive unit 21 is connected to the gearbox 22 to drive the gearbox 22. From the gearbox 22 is a drive shaft 20, which is connected via a shaft connector 3 to the drive shaft 30 of the first spinning pump unit 4.1 (see [link]). Figure 4 ).

[0049] The first spinning pump device 4.1 is fluid-tightly mounted on the adapter plate 5 via a threaded connection mechanism 8 having an assembly flange 10.

[0050] The adapter plate 5 also has a pipeline connection portion 75, which is arranged on the outer periphery of the adapter plate 5 such that the second spinning pump device 4.2 on the pipeline connection portion 75 side of the adapter plate 5 can also be assembled and driven on the adapter plate 5 in a fluid-sealed manner.

[0051] The second spinning pump device 4.2, which is also connected to the adapter plate 5 via a threaded connection mechanism 8, is preferably assembled with another mounting flange 10 on the second adapter plate 6 via a threaded connection mechanism 8 on the spinning pump connection side, i.e., the second connection side 62, of the second adapter plate 6. The second adapter plate 6, located away from the spinning pump connection side, i.e., the second connection side 62, and the first connection side 61 of the mounting flange 10, has a plurality of pipeline connection portions 76, which at least partially surround the central connection through hole 9.

[0052] The central connecting through-hole 9 passes approximately through the second adapter plate 6. The central connecting through-hole 9 is a special accessory that allows the supply line for supplying the synthetic fiber spinning fluid to the spinning pump system 1 to be connected to this accessory.

[0053] Figures 1 to 3 The spinning pump system 1 shown is particularly suitable for conveying and transporting spinning solutions used in the production of spandex fibers. However, the pump system and associated adapter plates are not limited to this specific spinning solution. Other spinning melts with the same viscosity can also be precisely conveyed and transported.

[0054] Figure 4 Showing according to Figure 3 A schematic diagram of the cross-section of section line II in the diagram.

[0055] Figure 4 A schematic cross-sectional view shows a first spinning pump device 4.1 and a second spinning pump device 4.2 in an assembled state, which have an adapter plate 5 and a second adapter plate 6 according to the invention.

[0056] The adapter board 5 has a first connecting side 51 and a second connecting side 53, the second connecting side being different from the first connecting side 51.

[0057] The first connecting side 51 has a first spinning pump connecting part 401, through which the second spinning pump device 4.2 is fluid-tightly connected and the drive shaft 31 of the second spinning pump device 4.2 is indirectly engaged with the drive shaft 30 of the first pump device 4.1 through a through hole 100 having a connecting sleeve 101 for driving.

[0058] Furthermore, the first connecting side 51 also has a pipeline connection portion 75, in which a plurality of attachments 7 are disposed. Attachments 7 allow a pipeline or rigid tube (not shown) to be attached to the adapter plate 5 and the second adapter plate 6 in a fluid-sealed and detachable manner. This pipeline guides the spinning fluid supplied by the first and second spinning devices to the corresponding spinning nozzle of the spinning device used to form and spin synthetic yarns.

[0059] Annex 7 is a connector suitable for assembling rigid pipelines and / or flexible hoses in a fluid-tight manner.

[0060] On the second connecting side 53 opposite to the first connecting side 51, the adapter plate 5 also has a second spinning pump connecting portion 402. The first spinning pump device 4.1 is fluid-tightly connected to the adapter plate 5 via the second spinning pump connecting portion 402 and is operably connected to the second spinning pump device 4.2 for driving.

[0061] like Figure 4 As shown, the drive shaft 30 of the first pump device 4.1 is connected to the drive shaft 31 of the second spinning device 4.2 via the connecting sleeve 101.

[0062] The first spinning pump device 4.1 can be assembled with the spinning pump assembly flange 10 and the threaded connection mechanism 8 to be connected to the adapter plate 5 in a fluid-sealed manner.

[0063] The flow connection in the spinning pump system 1 is made through the supply pipe 91 and the discharge pipe 92, respectively. The supply pipe 91 and the discharge pipe 92 are continuously arranged in the mounting flange 10 in the adapter plate 5 and the second adapter plate 6. The first and second spinning pump devices 4.1 and 4.2 can be mounted on the adapter plate by means of the mounting flange 10, and can be mounted on the first and second spinning pump devices 4.1 and 4.2 so as to deliver spinning fluid in the spinning pump system 1.

[0064] The supply and discharge of the spinning fluid are explained as follows:

[0065] Through the central connecting through-hole 9 and the supply pipe 91 in the second adapter plate 6, the spinning fluid is first distributed to the external gear pump plate 40 of the second spinning pump device 4.2, which is arranged in front and behind. According to the corresponding delivery volume of each driven external gear 44, a predetermined proportion is recovered from the flow of the spinning melt in the corresponding external gear pump plate 40 and is forcibly sent to the relevant accessory 7 in the second adapter plate 6.

[0066] according to Figures 1 to 6 In the illustrated embodiment, both the first spinning pump device 4.1 and the second spinning pump device 4.2 have five external gear pump plates 40, and each external gear pump plate has eight driven external gears 44 for conveying spinning fluid.

[0067] All 40 attachments 7 are configured in the adapter plate 5 and the second adapter plate 6. In this way, the five external gear pump plates 40, each having eight driven external gears 44, can deliver the spinning melt to the corresponding 40 attachments 7 in the adapter plate 5 and the second adapter plate 6.

[0068] The output capacity of pump system 1 can be increased without complexity by mounting adapter plate 5 onto a second spinning device 4.2 with an additional 40 attachments 7, such as... Figure 1 As shown.

[0069] Using the adapter plate 5 of the present invention, multiple additional accessories can be provided without requiring any additional expansion of the second adapter plate 6.

[0070] The adapter board 5 provides multiple functions. One of at least two spinning pump units 4.1, 4.2 with additional accessory 7 is connected to the shaft drive coupling 100, 101 for the second spinning pump unit 4.2.

[0071] The supply pipe 91 from the first spinning pump device 4.1 is in fluid communication with the relevant supply pipe 91 of the adapter plate.

[0072] The adapter plate 5 also has a supply pipe 91. The supply pipe of the adapter plate 5 is connected to the supply pipe 91 of the first spinning pump device 4.1.

[0073] Due to the meshing action of the driving external gears 43 and driven external gears 44, a predetermined proportion of spinning fluid is recovered in each external gear pump plate 40 and returned to the corresponding accessory 7 of the adapter plate 5 and the second adapter plate 6.

[0074] Ideally, the remainder of the fluid flow has reached the end of the respective supply pipe 91 of the first spinning pump device 4.1 and is delivered to the relevant accessory 7 of the adapter plate 5 via the final external gear pump plate 40.

[0075] For example, it can also be found from Figure 4 As can be seen in the image, the adapter plate 5 is formed by the first sub-adapter plate 54 and the second sub-adapter plate 55.

[0076] The pipeline groove and pipeline hole with complementary structure are configured in the corresponding first sub-adapter plate 54 and second sub-adapter plate 55, and the pipeline groove and pipeline hole respectively form a supply pipe 91 and a discharge pipe 92 or a discharge hole in the assembled state.

[0077] Figure 6 Showing according to Figure 4 A partial cross-sectional view of section line II-II. The partial cross-sectional view shows the segmented section line between the second adapter plate 6 and the second spinning pump device 4.2 when viewed along the direction of the assembly flange 10.

[0078] Figure 6 The cross-sectional view shows an internal view of one of the external gear pump plates 40 arranged in series with a first spinning pump device 4.1 and a second spinning pump device 4.2 having a driving external gear 43 and a driven external gear 44. A distribution pipe for dispensing the synthetic melt from the central connecting through-hole 9 is also shown.

[0079] The driving external gear 43 drives the driven external gear 44. The driving external gear 43 and the driven external gear 44 are arranged according to a planetary gearbox. Due to the meshing of the gears, a predetermined amount of synthetic fluid is drawn back from the branch of the central connecting through hole 9 and from the outer periphery of the driven gear that is being conveyed toward the discharge pipe 92. The discharge pipe 92 is fluid-tightly connected to the accessory of the corresponding adapter plate 5 or the second adapter plate 6.

[0080] The number of accessories 7 on adapter plate 5 is determined by the number of driven external gears 44 or pumps, enabling the synthesis fluid to be supplied to multiple connecting lines in a simple manner.

[0081] The number of accessories 7 on the adapter plate 5 may also include more or fewer accessories, depending on how many external gear pump plates 40 and driven external gears 44 are provided.

[0082] With the adapter board 5 of this invention, a simple upgrade of the existing pump system can be achieved without much complexity.
