Description

Technical Field

[0001] This utility model relates to the field of pipeline sealing technology, specifically to a pipeline connection device and a vibrating screen. Background Technology

[0002] During the production and drying process of lithium carbonate, some scale and clumps will form. After drying, these scale and clumps of lithium carbonate need to be separated. Only lithium carbonate that has reached the appropriate size can enter the subsequent packaging process.

[0003] Generally, separating scale and agglomerated lithium carbonate is accomplished using a vibrating screen. During operation, the main structure of the vibrating screen vibrates at a high frequency under the action of the vibrator. The lithium carbonate material is transported through rigid pipes (commonly stainless steel pipes). Therefore, to avoid the high-frequency vibration of the vibrating screen affecting the pipes, a flexible pipe is installed at both the inlet and outlet of the vibrating screen to connect with the rigid pipe.

[0004] At the connection between the flexible and rigid pipes, the joints may loosen under prolonged vibration of the vibrating screen, causing fine lithium carbonate powder to leak out from the loosened area. This leaked lithium carbonate is not only difficult to collect and is thus wasted, but it also pollutes the working environment. Utility Model Content

[0038] Because the end of the hose is folded during the connection process, the section of the hose located outside the connection is subjected to a downward pull during the operation of the vibrating screen. At this time, the pressure at the connection between the hose and the end of the connection increases, thereby preventing the hose from sliding on the connection and solving the problem of easy loosening at the connection between the hose and the material pipe.

[0048] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0049] Example 1

[0050] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This embodiment discloses a pipe connection device, including a material pipe 10, a flexible hose 20, an inner pressure block 30, an outer pressure block 40, and a locking assembly 50.

[0051] The pipe 10 has an L-shaped connecting part 11 at its opening. The connecting part 11 is annular and has an L-shaped cross-section. The connecting part 11 is installed on the outside of the opening of the pipe 10, so that the end of the pipe 10 forms a U-shaped cross-section.

[0052] The hose 20 is made of fabric and has a sealing layer inside, such as a layer of plastic. One end of the hose 20 is rolled up (folded inward) and fitted onto the U-shaped structure, completely wrapping the connecting part 11, so that one end of the hose 20 is located inside the U-shaped structure.

[0053] There are multiple inner pressure blocks 30, all located inside the U-shaped structure. All inner pressure blocks 30 are evenly distributed around the circumference of the material tube 10, and all inner pressure blocks 30 are pressed against the end of the hose 20.

[0054] There are also multiple outer pressure blocks 40, and the number of outer pressure blocks 40 is equal to the number of inner pressure blocks 30. All outer pressure blocks 40 correspond one-to-one with all inner pressure blocks 30. All outer pressure blocks 40 are arranged around the outside of the connecting part 11 around the circumference of the material tube 10, and all outer pressure blocks 40 are pressed on the section of the hose 20 that contacts the outside of the connecting part 11.

[0055] The locking assembly 50 is connected to all the inner pressure blocks 30 and all the outer pressure blocks 40, and is used to adjust the gap between the inner pressure blocks 30 and the outer pressure blocks 40.

[0056] The gap between the inner pressure block 30 and the outer pressure block 40 is adjusted by the locking assembly 50, so that the inner pressure block 30 and the outer pressure block 40 press the section of the hose 20 wrapped around the connector 11.

[0057] In this embodiment, when connecting the material tube 10 and the hose 20, the end of the hose 20 is rolled up and put on the connecting part 11 of the material tube 10. Then, the locking assembly 50 drives the inner pressure block 30 to press the end of the hose 20 located in the U-shaped structure, and the outer pressure block 40 presses the section of the hose 20 located outside the connecting part 11.

[0058] Because the end of the hose 20 is folded during the connection process, the section of the hose 20 located outside the connection part 11 is subjected to a downward pulling force during the operation of the vibrating screen 90. At this time, the pressure at the connection point between the hose 20 and the end of the connection part 11 will increase, thereby preventing the hose 20 from sliding on the connection part 11 and solving the problem of easy loosening at the connection between the hose 20 and the material pipe 10.

[0059] In one specific embodiment:

[0060] The connecting device also includes a housing 60 and a support housing 70. The housing 60 is annular and has a rectangular cross-section. The housing 60 is coaxially arranged with the material tube 10, and an annular groove 61 is provided at the bottom of the housing 60. The annular groove 61 is coaxial with the housing 60.

[0061] The support shell 70 is also an annular structure with a U-shaped cross-section. The support shell 70 is located inside the outer shell 60, connected to the outer shell 60, and positioned on the annular groove 61, so that the two sides of the support groove are connected to the two sides of the annular groove 61.

[0062] Multiple sliding grooves are provided on both sides of the support shell 70. All the inner pressure blocks 30 and outer pressure blocks 40 mentioned above are located in the sliding grooves of the support shell 70. The locking assembly 50 mentioned above is located inside the outer shell 60.

[0063] In this embodiment, the housing is configured as a carrier for the inner pressure block 30 and the outer pressure block 40. In use, the connecting part 11 is inserted into the support shell 70 from the annular groove 61 and is pressed tightly by the inner pressure block 30 and the outer pressure block 40 within the support shell 70.

[0064] In another specific embodiment:

[0065] The locking assembly 50 includes inner pressure rods 51, outer pressure rods 52 and a driving member. The number of inner pressure rods 51 is the same as the number of inner pressure blocks 30, and the number of outer pressure rods 52 is the same as the number of outer pressure blocks 40. All inner pressure rods 51 correspond one-to-one with all inner pressure blocks 30, and all outer pressure rods 52 correspond one-to-one with all outer pressure blocks 40.

[0066] The driving component is used to drive all the inner pressure rods 51 and all the outer pressure rods 52, thereby driving all the inner pressure blocks 30 and the outer pressure blocks 40 to move closer or further apart from each other.

[0067] Specifically, the inner pressure block 30 and the outer pressure block 40 are inclined force-bearing surfaces on the side away from the hose 20, and the ends of the inner pressure rod 51 and the outer pressure rod 52 are inclined pressure surfaces, with the force-bearing surface matching the pressure surface.

[0068] The driving component includes a connecting plate 53, a connecting ring 54, a gear ring 55, a gear 56, and a main shaft 57. The connecting plate 53 has a ring-shaped structure, with its bottom surface connected to the top ends of the inner pressure rod 51 and the outer pressure rod 52 on both sides, respectively. The connecting ring 54 is located on top of the connecting plate 53 and is coaxially aligned with it. The outer wall of the connecting ring 54 is also provided with external threads.

[0069] The gear ring 55 is rotatably mounted on the top of the inner side of the housing 60, and an internal thread matching the external thread is provided on the inner side of the gear ring 55. The main shaft 57 is rotatably mounted inside the housing 60, and the main shaft 57 is coaxially connected with the gear 56. One end of the main shaft 57 extends out of the housing 60 and is rotatably connected to the housing 60. The gear 56 meshes with the gear ring 55.

[0070] In this embodiment, the gear 56 is rotated by the main shaft 57, thereby driving the gear ring 55 to rotate. Then, through the thread matching relationship between the gear ring 55 and the connecting ring 54, the connecting ring 54 drives the connecting plate 53, the inner pressure rod 51 and the outer pressure rod 52 to move in the vertical direction. Then, through the force surface and the pressure surface, the inner pressure block 30 and the outer pressure block 40 are driven to move closer to each other.

[0071] Preferably, a hexagonal post is provided on one end of the spindle 57 that protrudes from the housing 60, so that the spindle 57 can be driven to rotate by a tool such as a wrench.

[0072] In another specific embodiment:

[0073] The connecting plate 53 is provided with multiple guide rods 58, which extend out of the outer shell 60 and are slidably connected to the outer shell 60. By setting the guide rods 58, the rotation of the connecting plate 53 and the connecting ring 54 can be prevented, thereby limiting the movement path of the connecting plate 53 and the connecting ring 54.

[0074] In another specific embodiment:

[0075] Both sides of the inner pressure block 30 and the outer pressure block 40 are provided with limiting grooves, and the support shell 70 is provided with limiting blocks 80 that match the limiting grooves. The limiting grooves are arranged in a direction perpendicular to the axis of the support shell 70.

[0076] In this embodiment, by setting a limiting groove and a limiting block 80, the movement trajectory of the inner pressing block 30 and the outer pressing block 40 can be restricted.

[0077] In another specific embodiment:

[0078] Anti-slip stripes are provided on the side of the inner pressure block 30 and the outer pressure block 40 that are in contact with the hose 20, and anti-slip textures are provided on both the inner and outer sides of the connecting part 11.

[0079] By setting anti-slip stripes and anti-slip patterns, the friction between the hose 20 and the connection part 11 can be enhanced, thereby improving the sealing performance.

[0082] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
