Description

Technical Field

[0001] This utility model relates to the technical field of metal powder industry, and in particular to a novel floating interface for equipment docking. Background Technology

[0002] When feeding or discharging materials into metal powder processing equipment and storage tanks, connection via a feed port flange is required. Due to the large size and weight of these equipment and tanks, connection can only be achieved using forklifts, lifting platforms, or overhead cranes. This leads to difficulties in connecting the feed port, requiring repeated connections. Furthermore, the impact force at the feed port during connection is significant, resulting in a short lifespan for rigid feed port flanges. To address these issues, our company has developed a floating interface for equipment connection, patent number 2024113159096. This patent employs a floating, split design, with radially movable space between the feed port flange and the core tube. This allows for connection between the metal powder tank and the metal powder processing equipment as long as the connection range is within the acceptable deviation. Lubricating gaskets are added to the friction points between the core tube and the feed port flange. While these gaskets extend the lifespan of the core tube, their short lifespan necessitates frequent disassembly and replacement. Utility Model Content

[0003] In view of the above problems, the purpose of this utility model is to provide a new type of floating interface for equipment docking, which can realize the rapid docking of metal powder processing equipment and the material inlet of storage tank, and at the same time extend the service life of the floating interface, so as to overcome the shortcomings of the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A novel floating interface for equipment docking includes: a cylindrical inlet flange consisting of a fixed flange, a spacer sleeve, and a limiting locking flange; a floating flange inserted into the inlet flange; a buffer unit disposed inside the inlet flange and located between the fixed flange and the floating flange; and a universal ball located between the floating flange and the limiting locking flange. The embedded section of the floating flange is inserted into the fixed flange, and the diameter of the embedded section is smaller than the diameter of the inner cylinder of the inlet flange. A radial adjustment gap is provided between the embedded section and the inner cylinder of the inlet flange. When subjected to pressure, the embedded section of the floating flange overcomes the elasticity of the buffer unit and moves up and down within the inlet flange. The universal ball is disposed on the limiting locking flange and contacts the shoulder of the embedded section. The universal ball is used to change the contact surface between the shoulder of the embedded section and the limiting locking flange from static friction to sliding friction.

[0006] As a preferred embodiment of this utility model, the buffer unit includes: an elastic hose, an upper clamping hose flange, a lower clamping hose flange, and limiting steel rings. The upper end face of the elastic hose rests on the lower end face of the fixed flange, and the lower end face of the elastic hose rests on the upper end face of the embedded section of the floating flange. The upper clamping hose flange fixes the upper end face of the elastic hose to the lower end face of the fixed flange with bolts, and the lower clamping hose flange fixes the lower end face of the elastic hose to the upper end face of the embedded section of the floating flange with bolts. Multiple limiting steel rings are evenly distributed and fitted on the outer side of the elastic hose. The limiting steel rings are used to prevent the elastic hose from deforming significantly after being subjected to excessive compressive force.

[0007] As a preferred embodiment of this utility model, the buffer unit further includes multiple return springs disposed between the upper and lower clamping hose flanges. The upper end of each return spring is fixedly connected to the upper clamping hose flange, and the lower end is fixedly connected to the lower clamping hose flange. The return springs are used to assist in buffering and returning the floating flange after it is compressed, as well as buffering and returning it after lateral movement.

[0008] As a preferred embodiment of this utility model, a first sealing wave groove is provided on the end face of the fixed flange that contacts the elastic hose, and a second sealing wave groove is provided on the end face of the floating flange that contacts the elastic hose. When the elastic hose is squeezed, it fills the first sealing wave groove and the second sealing wave groove.

[0009] As a preferred embodiment of this utility model, an annular groove is provided on the outer wall of the elastic tube from top to bottom, and the limiting steel ring is fitted inside the annular groove.

[0010] As a preferred embodiment of this utility model, the universal ball is a cylindrical heavy-duty universal ball, and the upper end face of the limiting locking flange is provided with multiple ball grooves in an annular shape, and the cylindrical heavy-duty universal ball is installed in the ball grooves.

[0011] As a preferred embodiment of this utility model, the limiting locking flange is composed of two semi-circular annular flanges that interlock in half.

[0012] As a preferred embodiment of this utility model, the floating flange includes: a pipe body, an upper locking boss integrally formed with the pipe body, and an embedded section integrally formed with the pipe body. The upper locking boss is connected to the metal powder docking port in the docking equipment via an electric valve. The embedded section is placed in the inner cavity of the port flange. The limiting locking flange limits the embedded section in the inner cavity of the port flange. The shoulder of the embedded section contacts the limiting locking flange via a universal ball.

[0013] As a preferred embodiment of this utility model, the fixed flange is fixedly connected to the upper end of the spacer sleeve by bolts, the lower end of the spacer sleeve is fixedly connected to the limiting locking flange by bolts, and the upper end of the fixed flange is connected to the metal powder docking port in the docking equipment.

[0014] As a preferred embodiment of this invention, the elastic tubing is made of natural rubber, nitrile rubber, fluororubber, fluorosilicone rubber, or silicone rubber.

[0015] The advantages and positive effects of this utility model are:

[0016] 1. The friction point between the floating flange and the limiting locking flange of this utility model is made into contact by setting a universal ball, thereby reducing the wear of the floating flange and extending its service life. Moreover, the elastic rubber tube, which acts as a buffer, can also play a sealing role by adopting a connection method that moves synchronously with the floating flange.

[0017] 2. This utility model adds a buffer unit inside the feed port flange to buffer the impact force during the docking process between the feed port flange and the core tube. The buffer unit adopts an integrally connected elastic rubber tube. The elastic rubber tube deforms and absorbs energy during the impact. After docking, the elastic rubber tube returns to its shape and can also play a sealing role. In addition, a limiting steel ring is fitted on the outer ring of the elastic rubber tube to prevent excessive deformation from causing the elastic rubber tube to explode, which would lead to leakage at the interface.

[0018] 3. This utility model adds a sealing corrugated groove inside the fixed flange as a seal. After being squeezed, the elastic tube fills the sealing corrugated groove and thus plays a sealing role. Similarly, the bottom surface of the embedded section of the floating flange, the inner cavity of the material port flange, and the end of the compression tube flange that contacts the elastic tube are also provided with sealing corrugated grooves. That is, both ends of the inner cavity of the fixed flange are sealed, thereby ensuring that the metal powder does not come into contact with the external air.

[0019] 4. This utility model designs the feed port flange as a split structure, that is, the fixed flange, the spacer sleeve and the limit locking flange are connected by bolts, so that the feed port flange does not need to be cast as a whole, which has the advantage of convenient processing.

[0020] 5. This utility model adds a return spring inside the feed port flange, which assists the elastic hose in buffering and resetting. Attached Figure Description

The cylindrical heavy-duty universal ball 5 is disposed on the limiting locking flange 3 and contacts the shoulder 8 of the embedded section 6. The cylindrical heavy-duty universal ball 5 is used to change the contact surface between the shoulder 8 of the embedded section 6 and the limiting locking flange 3 from static friction to sliding friction. The buffer unit includes: an elastic hose 9, an upper clamping hose flange 10, a lower clamping hose flange 11, limiting steel rings 12, and a return spring 13. The upper end face of the elastic hose 9 rests on the lower end face of the fixed flange 1, and the lower end face of the elastic hose 9 rests on the upper end face of the embedded section 6 of the floating flange 4. The upper clamping hose flange 10 is bolted to the lower end face of the fixed flange 1, and the lower clamping hose flange 11 is bolted to the upper end face of the embedded section 6 of the floating flange 4. Multiple limiting steel rings 12 are evenly distributed and fitted in the annular grooves on the outer side of the elastic hose 9. Multiple annular grooves are sequentially opened from top to bottom on the outer wall of the elastic hose. The limiting steel rings 12 are used to prevent the elastic hose 9 from deforming significantly after being subjected to excessive extrusion pressure. Multiple return springs 13 are arranged between the fixed flange 1 and the floating flange 4. The upper end of the return spring 13 is fixed to the upper clamping hose flange 10 through a spring limiting post, and the lower end of the return spring 13 is fixed to the lower clamping hose flange 11 through a spring limiting post. An expansion flange is fitted on the spring limiting post at the lower end of the return spring 13. The return spring 13 is used to assist the floating flange 4 in buffering and returning after being compressed, as well as in buffering and returning after lateral movement. A first sealing wave groove 14 is provided on the end face of the fixed flange 1 that contacts the elastic hose 9, a second sealing wave groove 15 is provided on the end face of the floating flange 4 that contacts the elastic hose 9, and a third sealing wave groove 16 is provided on the end faces of the upper clamping hose flange 10 and the lower clamping hose flange 11 that contact the elastic hose 9. When the elastic hose 9 is compressed, it fills the first sealing wave groove, the second sealing wave groove, and the third sealing wave groove 16 to achieve a sealing effect. The upper end face of the limiting and locking flange 3 is provided with multiple ball grooves in a circular shape, and the cylindrical heavy-duty universal ball 5 is installed in the ball grooves. The limiting and locking flange 3 is composed of two semi-circular flanges that interlock to facilitate the installation of the embedded section 6.

[0032] Furthermore, the floating flange 4 in this embodiment includes: a pipe body 17, an upper locking boss 18 integrally formed with the pipe body 17, and an embedded section 6 integrally formed with the pipe body 17.

[0035] Working principle: First, the fixed flange 1 is quickly fixed to the inlet of the metal powder processing equipment using a pneumatic valve. Then, the metal powder tank is transported to the inlet of the metal powder processing equipment by a crane. Finally, the upper locking boss 18 of the floating flange 4 is quickly fixed to the outlet of the metal powder tank using a pneumatic valve. Since the inner cavity of the floating flange 4 and the inlet flange has a radial adjustment gap 7, the connection is convenient during the docking process. The buffer force after docking is absorbed by the buffer unit, which can extend the service life of the inlet flange and the floating flange 4. In addition, the sealing wave groove of the docked inlet flange and the floating flange 4 can ensure the sealing performance of the inlet flange and the floating flange 4.
