Description

Technical Field

[0001] This utility model belongs to the field of pipeline connection technology, and specifically relates to a pipeline connection mechanism for a rising film concentrator. Background Technology

[0002] A rising film concentrator is a type of concentration equipment widely used in chemical, food, and pharmaceutical industries. It concentrates liquid materials based on a specific evaporation principle. The piping connection mechanism of the rising film concentrator is used to connect the pipes and related connecting parts of the concentrator, such as flange connection structures and welded connections.

[0003] The current flange connection structure requires selecting a suitable flange according to the different sizes of the pipes when connecting two pipes. Then, a sealing gasket is placed between the flanges, and the bolt holes are aligned. The bolts and nuts are used to achieve initial tightening. Finally, a torque wrench is used to tighten the bolts to the specified torque to complete the connection between the pipes.

[0004] However, this connection method consumes a lot of time during the installation, commissioning, maintenance, repair, or replacement of parts of the rising film concentrator, increasing equipment downtime and affecting production efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a pipeline connection mechanism for a rising film concentrator. Its advantage is that it enables quick disassembly and assembly of pipelines during maintenance and repair of the rising film concentrator, or quick connection between pipelines.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a pipe connection mechanism for a rising film concentrator, comprising two pipe bodies, which are interlocked on opposite sides, and a sealing ring is interlocked between the opposite sides of the two pipe bodies. Connecting components are slidably connected to opposite sides of the surfaces of the two pipe bodies. The connecting components include two connecting plates and four connecting blocks. The inner cavities of each pair of connecting plates are slidably connected to the pipe bodies on opposite sides, and the opposite sides of each pair of connecting blocks are interlocked with the pipe bodies. The side of each pair of connecting blocks away from the pipe bodies is slidably connected to the connecting plates. A positioning component is interlocked at the top of the two connecting plates. The positioning component includes two positioning blocks, and the opposite sides of the two positioning blocks are interlocked with the connecting blocks.

[0007] Using the above technical solution: When it is necessary to splice two pipe bodies during use, the user wraps the two connecting plates around the corresponding pipe body surface using the shaft pins, and after the connecting block is snapped into the pipe body, the two connecting plates are moved closer to the center of the two pipe bodies. After the connecting block is snapped into the pipe body and spliced ​​with the corresponding connecting block, the retaining shell is snapped into the two connecting plates. The distance between the retaining shells is adjusted by the electric push rod and then snapped into the connecting plates, thus completing the rapid splicing of the two pipe bodies. Furthermore, when it is necessary to adjust the number of connecting blocks in the positioning assembly according to the number of pipes with different mounting holes, before splicing and positioning the two pipes using the positioning assembly, the positioning shell can be rotated to cancel the snapping between the positioning block and the connecting block, and then the connecting block can be pulled out from inside the positioning shell, thus reducing the number of connecting blocks in the positioning assembly.

[0008] The present invention is further configured such that the left sides of the two connecting plates on opposite sides are movably connected by a pivot pin, and a plurality of retaining shells are respectively snapped between the opposite sides of the two connecting plates. A retaining plate is movably connected between the opposite sides of each pair of retaining shells. An electric push rod is fixedly installed on the top and bottom of the retaining plate, and the side of the electric push rod away from the retaining plate is fixedly installed with the retaining shell.

[0009] The above technical solution utilizes a movable connection between a connecting plate and a pivot pin, allowing the two connecting plates to rotate and open around the pivot pin, enabling rapid fitting or detachment of the pipe body. The grouped design of several retaining shells allows for flexible increases or decreases in quantity according to different requirements, and also enables uniform clamping from multiple points around the pipe circumference. The electric push rod extends and retracts to drive the relative movement of the retaining plate and retaining shell, allowing for precise control of the clamping force. Sufficient clamping force ensures a tight seal at the pipe connection, preventing leakage of high-temperature fluids, while stroke control prevents excessive clamping force from damaging the pipe. During disassembly, simply controlling the retraction of the electric push rod releases the clamp without manual prying, achieving rapid separation of the pipe during disassembly.

[0010] The present invention is further configured such that a limiting shell is fixedly installed at both the top and bottom of the fixing plate, and the surface of the limiting shell is in contact with the inner cavity of the fixing shell.

[0011] The above technical solution is adopted: through the sliding contact between the limiting shell and the inner cavity of the fixing shell, the movement trajectory of the fixing plate is precisely guided, preventing the fixing plate from deviating when the electric push rod drives the fixing plate to approach or move away from the pipe body, ensuring that the fixing plate always moves in a direction perpendicular to the pipe surface, reducing the shaking of the fixing plate during movement, and improving the stability of the clamping process.

[0012] The present invention is further configured such that a connecting groove is provided on the right side of each pair of connecting plates on opposite sides, and a connecting frame is engaged in the inner cavity of the connecting groove.

[0013] The above technical solution is adopted: the two connecting plates are locked by the snap-fit ​​of the connecting groove and the connecting bracket, and the opening and closing and fixing of the connecting plates are realized by the left shaft pin. When disassembling, only the connecting bracket needs to be removed to open the connecting plate and take out the pipe. There is no need to disassemble other parts, thus improving the efficiency of pipe disassembly and assembly.

[0014] The present invention is further configured such that the positioning component includes a positioning plate, the bottom of the positioning plate is slidably connected to a connecting plate, the top of the positioning plate is rotatably connected to a positioning shell, and the inner cavity of the positioning shell is fixedly installed with a positioning block.

[0015] The above technical solution allows for the adjustment of the positioning component's position through the sliding fit between the positioning plate and the connecting plate. This accommodates different numbers of connecting blocks added or removed from pipes with multiple mounting holes, or adjusts the spacing between the mounting holes to accommodate different distributions of connecting blocks. The rotating connection between the positioning shell and the positioning plate allows users to easily rotate the positioning shell when adding or removing connecting blocks, releasing the constraints of the positioning blocks on the connecting blocks, and quickly removing or inserting the connecting blocks. The operation requires no tools, balancing connection stability with the flexibility of component adjustment.

[0016] The present invention is further configured such that a positioning groove is provided on the top of the positioning plate, and a locking block is slidably connected to the inner cavity of the positioning groove, and the top of the locking block is fixedly installed with the positioning shell.

[0017] The above technical solution is adopted: through the sliding cooperation between the positioning groove and the locking block, the rotation trajectory of the positioning shell is precisely guided, preventing the positioning shell from shifting when rotating, ensuring that the positioning block can be accurately aligned with the locking position of the connecting block, and avoiding fixing failure due to misalignment.

[0018] In summary, this utility model has the following beneficial effects: 1. When it is necessary to splice two pipe bodies during use, the user wraps the two connecting plates around the corresponding pipe body surface with the shaft pin, and after the connecting block is snapped into the pipe body, the two connecting plates are moved closer to the center of the two pipe bodies. After the connecting block is snapped into the pipe body and spliced ​​with the corresponding connecting block, the retaining shell is snapped into the two connecting plates. After adjusting the distance between the retaining shells with the electric push rod, it is snapped into the connecting plates, thus completing the quick splicing of the two pipe bodies. 2. When the number of connecting blocks in the positioning assembly needs to be adjusted according to the number of pipes with different mounting holes, before splicing and positioning the two pipes through the positioning assembly, the positioning block and the connecting block can be unhooked by rotating the positioning shell, and then the connecting block can be pulled out from the inside of the positioning shell, thus reducing the number of connecting blocks in the positioning assembly.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Example 1: refer to Figure 1 , Figure 2 and Figure 3 A pipe connection mechanism for a rising film concentrator includes two pipe bodies 1, which are interlocked on opposite sides. A sealing ring 2 is interlocked between the opposite sides of the two pipe bodies 1. A connecting component 3 is slidably connected to opposite sides of the surfaces of the two pipe bodies 1. The connecting component 3 includes two connecting plates 301 and four connecting blocks 302. The inner cavities of each pair of connecting plates 301 are slidably connected to the pipe body 1 on opposite sides. The opposite sides of each pair of connecting blocks 302 are interlocked with the pipe body 1.

[0024] Furthermore, a limiting shell 306 is fixedly installed on both the top and bottom of the retaining plate 304, and the surface of the limiting shell 306 contacts the inner cavity of the retaining shell 303.

[0025] Furthermore, a connecting groove 307 is provided on the right side of each pair of connecting plates 301 on opposite sides, and a connecting bracket 308 is engaged in the inner cavity of the connecting groove 307.

[0026] Brief description of usage: When it is necessary to splice two pipe bodies 1 and sealing ring 2, the user wraps the two connecting plates 301 around the corresponding pipe body 1 surface using the shaft pins, and then snaps the connecting block 302 with the pipe body 1. Next, the user moves the two connecting plates 301 closer to the center of the two pipe bodies 1, snaps the connecting block 302 with the pipe body 1, and then splices it with the corresponding connecting block 302. Finally, the user uses the electric push rod 305 to adjust the retaining shell 303, which then snaps it with the two connecting plates 301. The electric push rod 305 locks the connection, and the positioning component 4 further secures the connecting block 302, thus completing the rapid splicing of the two pipe bodies 1. The connecting plate 301 is movably connected to the shaft pin, allowing the two connecting plates 301 to rotate and open around the shaft pin, enabling rapid fitting or detachment of the pipe body 1. The grouped design of several retaining shells 303 allows for flexible increase or decrease in quantity according to different requirements, and also enables uniform clamping from multiple points around the pipe circumference. The electric push rod 305 extends and retracts, driving the retaining plate 304 to... The relative movement of the retaining shell 303 allows for precise control of the clamping force. Sufficient clamping force ensures a tight seal at the pipe connection, preventing leakage of high-temperature fluids. Stroke control prevents excessive clamping force from damaging the pipe. Disassembly is achieved simply by retracting the electric push rod 305, eliminating the need for manual prying and enabling rapid separation of the pipe. The sliding contact between the limiting shell 306 and the inner cavity of the retaining shell 303 precisely guides the movement trajectory of the retaining plate 304, preventing the electric push rod 305 from driving the retaining plate 304. 4. When the pipe body 1 is approached or moved away, the offset occurs, ensuring that the retaining plate 304 always moves in a direction perpendicular to the pipe surface, reducing the shaking of the retaining plate 304 during movement and improving the stability of the clamping process; the two connecting plates 301 are locked by the snap-fit ​​of the connecting groove 307 and the connecting bracket 308, and the opening and closing and fixing closed-loop operation of the connecting plate 301 is realized with the left shaft pin. When disassembling, only the connecting bracket 308 needs to be removed to open the connecting plate 301 and take out the pipe without disassembling other parts, thus improving the efficiency of pipe disassembly and assembly.

[0027] Example 2: refer to Figure 1 and Figure 4 A pipe connection mechanism for a rising film concentrator includes two connecting plates 301, with a positioning component 4 snapped onto the top of the two connecting plates 301. The positioning component 4 includes two positioning blocks 403, with the opposite sides of the two positioning blocks 403 snapped onto the connecting block 302.

[0028] Furthermore, the positioning component 4 includes a positioning plate 401, the bottom of which is slidably connected to the connecting plate 301, and a positioning shell 402 is rotatably connected to the top of the positioning plate 401. The opposite side of the inner cavity of the positioning shell 402 is fixedly installed with the positioning block 403.

[0029] Furthermore, a positioning groove 404 is provided on the top of the positioning plate 401, and a locking block 405 is slidably connected to the inner cavity of the positioning groove 404. The top of the locking block 405 is fixedly installed with the positioning shell 402.

[0030] Brief description of usage: When adjusting the number of connecting blocks 302 in the positioning assembly 4 according to the number of pipes with different mounting holes, before splicing and positioning two pipes using the positioning assembly 4, the positioning shell 402 can be rotated to disengage the positioning block 403 from the connecting block 302, and then the connecting block 302 can be pulled out from inside the positioning shell 402 to reduce the number of connecting blocks 302 in the positioning assembly 4. If the number of connecting blocks 302 needs to be increased, add the same positioning assembly 4 and connecting blocks 302, slide the new connecting block 302 into the inner cavity of the positioning shell 402, and rotate the positioning shell to engage the positioning block 403 with the connecting block 302 to increase the number of connecting blocks 302. If the position of the connecting block 302 needs to be changed, before the connecting assembly 3 locks the pipe, slide the positioning plate 401 inside the connecting plate 301 to change the position of the connecting block 302. The position can be changed; through the sliding engagement of the positioning plate 401 and the connecting plate 301, the position of the positioning component 4 can be adjusted to accommodate different numbers of connecting blocks 302 added or removed from multi-mounting-hole pipes, or to adjust the spacing between the connecting blocks 302 and the mounting holes to accommodate different distributions of connecting blocks 302. The rotatable connection between the positioning shell 402 and the positioning plate 401 allows the user to rotate the positioning shell 402 when adding or removing connecting blocks 302, releasing the constraint of the positioning block 403 on the connecting block 302, and quickly removing or inserting the connecting block 302. The operation requires no tools, balancing connection stability and component adjustment flexibility. Through the sliding engagement of the positioning groove 404 and the locking block 405, the rotation trajectory of the positioning shell 402 is precisely guided, preventing the positioning shell 402 from shifting during rotation, ensuring that the positioning block 403 can accurately align with the locking position of the connecting block 302, and avoiding fixation failure due to misalignment.
