Description

Technical Field

[0001] This utility model mainly relates to the field of rotary evaporators, specifically to a dual explosion-proof mechanical support mechanism for rotary evaporators. Background Technology

[0002] Rotary evaporators are core equipment in laboratories and industries such as chemistry, biology, and pharmaceuticals, used for material concentration, solvent recovery, and separation and purification. Their basic working principle involves heating the material in the rotary distillation flask at a constant temperature to ensure uniform heating, while simultaneously accelerating solvent evaporation under negative pressure, and achieving efficient recovery through a condensation system. In this equipment, the connection mechanism between the rotary distillation flask and the feed pipe is a key component ensuring stable system operation, reliable sealing, and operational safety.

[0003] Traditional rotary evaporators typically connect the rotary distillation flask and feed tube using the following method: a common design uses a standard ground glass flange interface, employing clamps or spring clips to provide axial pressure for sealing. In this structure, the feed tube is driven by an external motor to rotate the entire connection, thus causing the distillation flask to rotate accordingly. However, this method has significant drawbacks in practical applications: Because rotary distillation flasks are typically made of glass, they are subjected to complex mechanical and thermal stresses under high-speed rotation and negative pressure conditions. The clamping method of ground flanges and clamps can easily cause stress concentration in localized areas at the flask neck. Especially when processing low-boiling-point, volatile, or potentially reactive materials, the system pressure may fluctuate drastically, causing the glass joints to shatter due to uneven stress, posing a serious safety hazard.

[0019] See attached document Figure 1-3 A dual explosion-proof mechanical support mechanism for a rotary evaporator includes a connecting pipe structure 1, one end of which is provided with a rotary distillation flask structure 2. A rotary distillation flask structure 2 includes a rotary distillation flask body 201. A positioning tube 202 is provided at one end of the rotary distillation flask body 201. An outer locking ring 203 is provided on the outer wall of the positioning tube 202. An inner guide ring 204 is provided on the inner side of the positioning tube 202. The cross-section of the inner guide ring 204 is an isosceles triangle. An inner locking ring 205 is provided at the bottom of the outer wall of the inner guide ring 204. The longitudinal cross-sections of the inner locking ring 205 and the outer locking ring 203 are right trapezoids. The bottom of the outer locking ring 203 is provided with a protrusion, and the number of the inner locking rings 205 is set to multiple. The multiple inner locking rings 205 are arranged in a ring on the inner wall of the inner guide ring 204. The first locking block 108 on the outer wall of the positioning tube 202 will push the first rotating bar 107 to rotate and squeeze the planar spiral spring 106. After the first locking block 108 has completely passed the positioning tube 202, the planar spiral spring 106 pushes the first rotating bar 107 to reset, so that the top plane of the first locking block 108 and the bottom plane of the outer locking ring 203 fit together. Simultaneously, the second rotating bar 115 is also pushed to rotate by the internal guide ring 204 and squeezes the first rotating bar 107. After the second rotating bar 115 has completely passed the internal guide ring 204, the first rotating bar 107 pushes the second rotating bar 115 to reset. Then, the second rotating bar 115 drives the second locking block 116 to fit against the outer wall of the internal guide ring 204. After that, the rotating distillation flask body 201 is rotated 15° so that the protrusions of the internal locking ring 205 and the outer locking ring 203 fit against the first locking block 108 and the second locking block 116 respectively. Then, the rotating distillation flask structure 2 can be driven to rotate in one direction through the connecting pipe structure 1.

[0020] Furthermore, the connecting pipe structure 1 includes a connecting pipe body 101. An installation ring 102 is provided on the outer wall of the connecting pipe body 101. Dampers 103 are rotatably connected to both sides of the outer wall of the installation ring 102. A positioning block 104 is provided on the outer wall of the bottom of the connecting pipe body 101. A rotating shaft 105 is rotatably connected inside the positioning block 104. A planar spiral spring 106 is provided between the positioning block 104 and the rotating shaft 105. A first rotating bar 107 is provided on the outer wall of the rotating shaft 105, and a first locking block is provided at one end of the first rotating bar 107. 108. A bracket 109 is provided on the outer wall of the bottom of the connecting pipe body 101. A positioning ring 110 is provided at the bottom of the bracket 109. A rotating ring 111 is rotatably connected to the inner wall of the positioning ring 110. A pushing block 112 is provided on the inner wall of the rotating ring 111. An auxiliary groove 113 is opened in the middle of the pushing block 112. A sealing ring 114 is provided at one end of the connecting pipe body 101. A second rotating bar 115 is rotatably connected to the bottom of the inner wall of the connecting pipe body 101. A planar spiral spring 1 is provided between the second rotating bar 115 and the connecting pipe body 101. 06. One end of the second rotating bar 115 is provided with a second locking block 116. When the connecting pipe structure 1 and the rotary distillation flask structure 2 need to be connected and require double explosion-proof support to fix the rotary distillation flask structure 2, the rotary distillation flask structure 2 is inserted into the outer wall of the connecting pipe body 101, and one end of the rotary distillation flask structure 2 is fitted with the sealing ring 114 to seal the rotary distillation flask structure 2. Then, the planar spiral spring 106 and the planar spiral spring 106 respectively engage with different positions inside the rotary distillation flask structure 2. Then, the rotating ring 111 is manually rotated. The rotating ring 111 rotates on the inner wall of the positioning ring 110. The rotating ring 111 drives the inner pushing block 112 to rotate. The pushing block 112 pushes the first rotating strip 107 to rotate. The outer wall of the first rotating strip 107 engages with the auxiliary groove 113, thereby fixing the position of the first rotating strip 107. The first locking block 108 at one end of the first rotating strip 107 engages with the outer wall of the rotary distillation flask structure 2. Then, the rotary distillation flask structure 2 is rotated 15° so that the protrusions of the inner locking ring 205 and the outer locking ring 203 respectively engage with the first locking block 108 and the second locking block 116.

[0021] Installation and initial positioning Insert the positioning tube 202 of the rotary distillation flask structure 2 axially into the connecting tube body 101 until the bottle mouth fits against the sealing ring 114 to achieve a preliminary seal.

[0022] During insertion, the positioning tube 202 pushes the first rotating bar 107 and the second rotating bar 115 to rotate outward and inward respectively, compressing the corresponding planar spiral spring 106.

[0023] Locking and anti-rotation After the positioning tube 202 is fully inserted, the two planar spiral springs 106 respectively push the first rotating bar 107 and the second rotating bar 115 to reset, so that: The first locking block 108 engages below the outer locking ring 203; The second card block 116 engages below the internal locking ring 205.

[0024] At this point, the rotary distillation flask can only rotate freely in one direction, and is blocked in the opposite direction by the inclined surface between the protrusion and the locking block.

[0025] Double locking and explosion-proof reinforcement Manually rotating the rotating ring 111, through the cooperation of the pushing block 112 and the auxiliary groove 113, pushes the first rotating bar 107 to rotate further and lock, thereby enhancing the constraint force of the outer locking ring 203.

[0026] This creates a dual mechanical support system, both internal and external: Outer side: First locking block 108 + outer locking ring 203; Inside: Second locking block 116 + internal locking ring 205.

[0027] This design disperses the stress at the glass bottle opening, avoids localized stress concentration, and significantly improves explosion-proof capability.

[0028] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, 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. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
