Description

Technical Field

[0001] This utility model relates to the field of vacuum distillation technology, specifically to a vacuum distillation apparatus with a condenser tube that can be quickly disassembled and assembled. Background Technology

[0002] Vacuum distillation technology is widely used in chemical experiments and industrial production due to its advantages of lowering the boiling point of liquids and preventing the decomposition of heat-sensitive substances. Its core equipment, the vacuum distillation apparatus, typically consists of components such as a distillation flask, condenser, receiver, and vacuum pump. Among these components, the connection structure between the condenser and the condensate inlet pipe directly affects the equipment's assembly / disassembly efficiency, operational stability, and sealing performance.

[0003] In existing technologies, the connection between the condenser tube and the condensate inlet pipe is mostly achieved through bolt fastening, flange connection, or clamp fixing. These connection methods have significant drawbacks: First, the disassembly and assembly process requires tools such as wrenches and screwdrivers, making the operation cumbersome. This is especially time-consuming and labor-intensive, particularly during experiments where condenser tubes are frequently replaced or during batch maintenance of equipment in industrial production, severely impacting work efficiency. Second, rigid connection structures such as bolts and flanges require high installation precision. If there are deviations during installation, the sealing surfaces may not fit tightly, leading to gas or liquid leaks. This not only affects the distillation vacuum but may also cause raw material waste or safety hazards. Third, under high-temperature distillation conditions, metal connection components are prone to thermal expansion and deformation, leading to loosening of the connection. This further reduces the stability of the fixation and the reliability of the seal, requiring frequent shutdowns for maintenance and increasing production costs.

[0004] In view of the above, in order to overcome the above technical problems, this utility model designs a vacuum distillation apparatus with a condenser tube that can be quickly disassembled and assembled, thus solving the above technical problems. Utility Model Content

[0005] The technical objective of this invention is to provide a vacuum distillation apparatus with a condenser tube that can be quickly disassembled and assembled, enabling tool-free quick disassembly and assembly of the condenser tube and the condensate inlet pipe, while ensuring the stability and sealing reliability of the equipment during operation and improving cooling efficiency.

[0006] To achieve the above-mentioned technical objectives, this utility model provides the following technical solution: This utility model provides a vacuum distiller with a quickly detachable condenser tube, comprising a condensate inlet pipe and a condenser tube. The condenser tube is installed at the right end of the condensate inlet pipe to transport the condensate generated during distillation into the condenser tube. Its right end connects to the left end of the condenser tube, and its outer wall fits the inner wall of a fixed gas bladder to ensure a tight fit when the fixed gas bladder expands. A water outlet pipe is installed on the side of the condenser tube near the condensate inlet pipe, and a water inlet pipe is installed on the side of the other end of the condenser tube. The water outlet pipe is located near the condensate inlet pipe, and the water inlet pipe is located at the end away from the condensate inlet pipe. Both pipes have the same diameter and are connected to the interior of the condenser tube, forming a circulation channel for the cooling liquid. The condenser tube has a flow tube installed inside, which is spiral in shape. A fixing component is installed at one end of the condenser tube near the water vapor inlet pipe. The fixing component guides the liquid flow through the spiral blades in the condenser tube, so that the flowing liquid squeezes the rotating blades. The squeezed rotating blades drive the rotating ring to rotate through the squeezing force. The rotating ring drives the adjusting ring to rotate. The rotating adjusting ring drives the sliding block to move in a circular direction through the action of the arc groove and the sliding groove. The moving sliding block squeezes the water vapor inlet pipe through the air bladder.

[0007] Preferably, the fixing component includes a fixing ring, a rotating ring, and a support ring. The fixing component is the core component for quickly assembling and disassembling the condenser tube and the condensate inlet tube. The fixing ring is fixedly installed on the inner wall of the condenser tube near the condensate inlet tube. Fixing blocks are arranged in an array on the left end of the fixing ring. A rotating ring is rotatably installed on the inner wall of the fixing ring. Rotating blades are arranged in an array on the right side of the rotating ring. The rotating blades have an arc-shaped cross-section. Restoration blocks are arranged in an array on the side of the rotating ring. A support ring is installed on the inner wall of the rotating ring. The support ring is rotatably connected to the rotating ring, and the inner wall of the support ring is fixed to the outer wall of the flow tube.

[0008] Preferably, the number of fixing blocks and the number of restoring blocks are the same, and a restoring spring is engaged between the fixing blocks and the restoring blocks.

[0009] Preferably, an adjusting ring is fixedly installed on the left side of the rotating ring, and an arc-shaped groove is arrayed on the adjusting ring. A fixing ring is rotatably installed on the left side of the adjusting ring, and a fixing airbag is installed on the inner wall of the fixing ring.

[0010] Preferably, the fixed ring has an array of sliding grooves on the side near the adjusting ring, the number of the sliding grooves being the same as the number of the arc-shaped grooves, and a sliding block is slidably installed inside the sliding groove. The sliding block has an L-shaped cross-section, and the short side of the sliding block is located inside the arc-shaped groove.

[0011] Preferably, the side array of the fixed airbag is connected to a raised airbag, which is located inside the sliding groove and at the lower end of the long side of the sliding block. The raised airbag is connected to the fixed airbag, made of the same elastic material, and is arrayed on the side of the fixed airbag, located inside the sliding groove and at the lower end of the long side of the sliding block. When the sliding block moves towards the center, its long side compresses the raised airbag, forcing the gas inside the raised airbag into the fixed airbag, causing the fixed airbag to inflate. When the sliding block returns to its original position, the raised airbag returns to its original shape, and the gas inside the fixed airbag flows back, achieving pressure relief and contraction.

[0012] Preferably, the inner wall of the condenser tube is equipped with helical blades. The spacing of the helical blades is the same as the spacing of the flow tube, and the positions of the helical blades and the flow tube differ by half a spacing. The helical flow tube is used to increase the contact area between the condensed vapor and the cooling liquid, thereby improving condensation efficiency. Fixed to the inner wall of the condenser tube, with the helical direction being the same as that of the flow tube, it guides the cooling liquid to flow helically along the inner wall of the condenser tube, ensuring precise flow of the liquid to the flow tube, while simultaneously squeezing the rotating blades to generate driving force. The spacing of the blades is the same as the spacing of the flow tube, but their positions are offset by half a spacing, ensuring that the cooling liquid can fully envelop the flow tube, further optimizing the contact effect between the cooling liquid and the flow tube.

[0013] The beneficial effects of this utility model are as follows: 1. The fixing components are automatically fixed by the flow of cooling liquid. When disassembling, the components are reset by the return spring. No tools such as wrenches and screwdrivers are needed throughout the process. The operation is simple and convenient, which greatly shortens the disassembly and assembly time. It is especially suitable for scenarios where condenser tubes are frequently replaced in experiments or batch equipment maintenance in industrial production, which significantly improves work efficiency.

[0014] 2. High stability: The dual fixing mechanism ensures the stability of equipment operation: The first fixing is achieved by the sliding block being squeezed by the flow of cooling liquid to compress the protruding air bladder, so that the fixing air bladder expands and fits against the outer wall of the condensate inlet pipe; the second fixing utilizes the increase in water temperature during the distillation process to further expand the gas inside the fixing air bladder, increasing the squeezing force on the condensate inlet pipe, effectively avoiding the problem of loose connection under high temperature conditions, and ensuring long-term stable operation of the equipment.

[0015] 3. Reliable sealing performance: When the fixed airbag inflates, it can fit tightly against the outer wall of the condensate inlet pipe to form a flexible sealing surface. This can adapt to minor dimensional deviations in the outer wall of the condensate inlet pipe and avoid sealing failure caused by insufficient installation accuracy of rigid connections. At the same time, the raised airbag is connected to the fixed airbag to ensure that the fixed airbag always maintains sufficient air pressure, further enhancing the sealing reliability and preventing air and liquid leakage.

[0016] 4. Improved cooling efficiency: The condenser tube is designed with a spiral flow tube and spiral blades. The spiral blades guide the cooling liquid to flow spirally along the inner wall of the condenser tube. The flow tube and spiral blades are spaced at the same distance but staggered by half a distance, so that the cooling liquid can fully wrap the flow tube, increase the heat exchange area between the condensed gas and the cooling liquid, accelerate the heat transfer speed, significantly improve the condensation cooling efficiency, and shorten the distillation cycle.

[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figure 1 , 2 As shown in Figures 3, 4, 5, 6, and 7, this utility model provides a vacuum distillation apparatus with a quickly detachable condenser tube 2. It includes a condensate inlet pipe 1 and a condenser tube 2. The condenser tube 2 is installed at the right end of the condensate inlet pipe 1 to transport the condensate generated during distillation into the condenser tube 2. Its right end is connected to the left end of the condenser tube 2, and its outer wall is adapted to the inner wall of the fixing gas bag 46 to ensure a tight fit when the fixing gas bag 46 expands. A water outlet pipe 21 is installed on the side of the condenser tube 2 near the condensate inlet pipe 1, and a water inlet pipe 22 is installed on the side of the other end of the condenser tube 2. The water outlet pipe 21 is closer to the condensate inlet pipe 1, and the water inlet pipe 22 is located at the end away from the condensate inlet pipe 1. Both pipes have the same diameter and are connected to the interior of the condenser tube 2, forming a circulation channel for the cooling liquid. The condenser tube 2 has a flow tube 3 installed inside. The flow tube 3 is spiral in shape. A fixing component 4 is installed at one end of the condenser tube 2 near the water condensate inlet pipe 1. The fixing component 4 guides the liquid flow through the spiral blades 23 in the condenser tube 2, so that the flowing liquid squeezes the rotating blades 421. The squeezed rotating blades 421 drive the rotating ring 42 to rotate through the squeezing force. The rotating ring 42 drives the adjusting ring 44 to rotate. The rotating adjusting ring 44 drives the sliding block 452 to move in a circular direction through the action of the arc groove 441 and the sliding groove 451. The moving sliding block 452 squeezes the water condensate inlet pipe 1 through the air bladder.

[0028] like Figure 2 , 3 As shown in Figures 4 and 5, the fixing component 4 includes a fixing ring 41, a rotating ring 42, and a support ring 43. The fixing component 4 is the core component for quickly assembling and disassembling the condenser tube 2 and the condensate inlet pipe 1. The fixing ring 41 is fixedly installed on the inner wall of the condenser tube 2 near the condensate inlet pipe 1. Fixing blocks 411 are arrayed on the left end of the fixing ring 41. The rotating ring 42 is rotatably installed on the inner wall of the fixing ring 41. Rotating blades 421 are arrayed and fixedly installed on the right side of the rotating ring 42. The cross-sectional shape of the rotating blades 421 is arc-shaped. Restoration blocks 422 are arrayed on the side of the rotating ring 42. The support ring 43 is installed on the inner wall of the rotating ring 42. The support ring 43 is rotatably connected to the rotating ring 42, and the inner wall of the support ring 43 is fixed on the outer wall of the flow pipe 3.

[0029] The rotating ring 42 is rotatably mounted on the inner wall of the fixed ring 41 and can rotate around the axis of the fixed ring 41. Rotating blades 421 are fixed in an array along the circumferential direction on its right side. The cross-section of the rotating blades 421 is arc-shaped. The arc design can increase the contact area with the cooling liquid, which facilitates the thrust generated by the liquid flow to drive the rotating ring 42 to rotate. The side of the rotating ring 42 is equipped with a set of recovery blocks 422. The recovery blocks 422 correspond one-to-one with the fixed blocks 411. A recovery spring 423 is engaged between the two. The recovery spring 423 is used to drive the rotating ring 42 to reverse and reset during disassembly.

[0030] like Figure 3 , 4 As shown in Figure 5, the number of fixing blocks 411 and the number of restoring blocks 422 are the same, and a restoring spring 423 is engaged between the fixing blocks 411 and the restoring blocks 422.

[0031] like Figure 3 , 4 As shown in Figures 5, 6, and 7, an adjusting ring 44 is fixedly installed on the left side of the rotating ring 42. The adjusting ring 44 has an array of arc-shaped grooves 441. A fixing ring 45 is rotatably installed on the left side of the adjusting ring 44. A fixing airbag 46 is installed on the inner wall of the fixing ring 45.

[0032] The adjusting ring 44 has an array of arc-shaped grooves 441 along the circumferential direction. The number of arc-shaped grooves 441 is the same as that of the sliding grooves 451. The groove trajectory is designed to be inclined from away from the center to near the center, which is used to drive the sliding block 452 to move towards the center when rotating.

[0033] like Figure 5 , 6 As shown in Figure 7, the fixed ring 45 has an array of sliding grooves 451 on the side near the adjusting ring 44. The number of sliding grooves 451 is the same as the number of arc grooves 441. A sliding block 452 is slidably installed inside the sliding groove 451. The cross-sectional shape of the sliding block 452 is L-shaped, and the short side of the sliding block 452 is located inside the arc groove 441.

[0034] The cross-section is L-shaped, with its short side inserted into the arc groove 441 of the adjusting ring 44, and its long side slidably installed in the sliding groove 451 of the fixed ring 45. When the adjusting ring 44 rotates, the groove wall of the arc groove 441 pushes the short side of the sliding block 452, causing the sliding block 452 to move along the sliding groove 451 towards the center, or to reset away from the center under the action of the restoring spring 423.

[0035] like Figure 5 , 6As shown in Figure 7, the side array of the fixed airbag 46 is connected to a raised airbag 461. The raised airbags 461 in the array are located inside the sliding groove 451, and the raised airbags 461 are located at the lower end of the long side of the sliding block 452. The airbags 461 are connected to the fixed airbag 46, made of the same elastic material as the fixed airbag 46, and are arranged in an array on the side of the fixed airbag 46, located inside the sliding groove 451, at the lower end of the long side of the sliding block 452. When the sliding block 452 moves towards the center, its long side compresses the raised airbags 461, forcing the gas inside the raised airbags 461 into the fixed airbag 46, causing the fixed airbag 46 to inflate. When the sliding block 452 resets, the raised airbags 461 return to their original shape, and the gas inside the fixed airbag 46 flows back, achieving depressurization and contraction.

[0036] like Figure 1 , 2 As shown in Figure 3, the inner wall of the condenser tube 2 is equipped with spiral blades 23. The spacing of the spiral blades 23 is the same as the spacing of the flow tube 3, and the positions of the spiral blades 23 and the flow tube 3 differ by half a spacing. The spiral flow tube 3 is used to increase the contact area between the condensed gas and the cooling liquid, thereby improving the condensation efficiency. Fixed on the inner wall of the condenser tube 2, the spiral direction is the same as that of the flow tube 3. It is used to guide the cooling liquid to flow spirally along the inner wall of the condenser tube 2, so that the liquid flows precisely to the flow tube 3. At the same time, it squeezes the rotating blades 421 to generate driving force. The spacing of the blades is the same as the spacing of the flow tube 3, but the positions are offset by half a spacing, ensuring that the cooling liquid can fully wrap the flow tube 3, further optimizing the contact effect between the cooling liquid and the flow tube 3.

[0037] In operation, the fixing process of this utility model is as follows: the right end of the condensate inlet pipe 1 is inserted into the left end of the condenser pipe 2, so that the outer wall of the condensate inlet pipe 1 is aligned with the inner wall of the fixing airbag 46; the equipment is started, and the cooling liquid enters the condenser pipe 2 through the water inlet pipe 22. Under the guidance of the spiral blades 23, it flows spirally along the inner wall of the condenser pipe 2. The flowing cooling liquid impacts and squeezes the arc-shaped rotating blades 421 on the rotating ring 42, generating a thrust along the circumference of the rotating ring 42, which drives the rotating ring 42 to rotate around the support ring 43; when the rotating ring 42 rotates, the adjusting ring 44 on its left side rotates synchronously, and the arc-shaped groove 441 on the adjusting ring 44 pushes the sliding... The short side of block 452 causes the sliding block 452 to move towards the center along the sliding groove 451 of the fixed ring 45; the long side of the sliding block 452 squeezes the protruding air bladder 461 during the movement, and forces the gas in the protruding air bladder 461 into the fixed air bladder 46. After the fixed air bladder 46 expands, it fits tightly against the outer wall of the condensate inlet pipe 1, thereby fixing and sealing the condensate inlet pipe 1 and the condenser pipe 2; during the distillation process, the temperature inside the condensate inlet pipe 1 rises due to the heat released by the condensate, and the gas in the fixed air bladder 46 (46) expands due to the heat, further increasing the squeezing force on the outer wall of the condensate inlet pipe 1, and enhancing the fixing stability and sealing effect.

[0038] Disassembly process: Turn off the equipment and stop supplying cooling liquid to the inlet pipe 22. The cooling liquid in the condenser pipe 2 is discharged through the outlet pipe 21, and the rotating blade 421 loses liquid thrust. At this time, the restoring spring 423 between the fixed block 411 and the restoring block 422 releases elastic potential energy, pulling the restoring block 422 to drive the rotating ring 42 to rotate in the opposite direction. When the rotating ring 42 rotates in the opposite direction, the adjusting ring 44 rotates in the opposite direction simultaneously. The arc groove 441 pushes the short side of the sliding block 452, causing the sliding block 452 to reset along the sliding groove 451 in the direction away from the center. The long side of the sliding block 452 leaves the protruding airbag 461. The protruding airbag 461 returns to its original shape under its own elastic action. The gas in the fixed airbag 46 flows back to the protruding airbag 461. The fixed airbag 46 depressurizes and contracts, separating from the outer wall of the condenser gas inlet pipe 1. At this time, the condenser gas inlet pipe 1 can be pulled out directly, completing the quick disassembly of the condenser pipe 2 and the condenser gas inlet pipe 1.
