Description

Technical Field

[0001] This utility model relates to the field of distillation instrument technology, and in particular to a glass distillation instrument. Background Technology

[0002] A distillation apparatus is a device that separates substances using distillation. Its design consists of a stoppered round-bottom distillation flask and a serpentine condenser tube, which are then fitted together with a frosted finish. The principle is to use distillation to gradually evaporate a mixture of liquids with different boiling points inside the distillation flask, continuously removing the generated vapors and cooling them in the condenser tube, thereby achieving the purpose of separation and purification of the mixture. It is suitable for waterworks, epidemic prevention stations, and laboratories of scientific research institutions for water quality analysis and fractional purification of various organic solvents.

[0003] However, distillers are usually used in combination with condensers. In experiments, the distilled medium is condensed into a liquid through heat exchange in the condenser. The outlet of the distiller and the inlet of the condenser are connected by a rubber sleeve or a plug. The plug is usually fitted onto the outer wall of the outlet pipe of the condenser and inserted into the inlet of the condenser in a conical shape. The rubber sleeve is made of soft material and fits onto the outer wall of the outlet of the distiller and the inlet of the condenser. The connection process is inconvenient and the use is limited by the model of the equipment. Therefore, we propose a glass distillation instrument to solve the existing problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a glass distillation instrument.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A glass distillation instrument, comprising a distillation flask, a sleeve, a steam pipe, a condenser pipe, a heat exchange shell, a pressure sleeve, a conical tube, and a pull rod. A heat exchange shell is provided on one side of the distillation flask, and a condenser pipe runs through the interior of the heat exchange shell. A steam pipe is provided at the upper end of the distillation flask, and a conical tube is provided at the lower end of the steam pipe. A support ring is fitted onto the outer wall of the steam pipe, and a spring is provided at the lower end of the support ring. A pressure sleeve is provided at the lower end of the spring. Bearing seats arranged in a circular array are provided on the outer wall of the steam pipe. A rotating shaft is rotatably mounted inside the bearing seats. A connecting rod is provided at one end of the rotating shaft, and a pressure block is provided at the lower end of the connecting rod. A torsion spring is fitted onto the outer side of the rotating shaft, with its two ends connected to the bearing seats and the connecting rod, respectively.

[0006] Preferably, the lower end of the pressure sleeve is rotatably fitted with a ring-shaped array of ball bearings, which roll and adhere to the outer wall of the connecting rod. The ball bearings reduce friction during passage as the pressure sleeve holds the connecting rod.

[0007] Preferably, the outer wall of the support ring is provided with sliders arranged in a ring array, and the upper end of the pressure sleeve is provided with guide rails arranged in a ring array and slidably installed inside the sliders. When the pressure sleeve moves longitudinally, it slides on the outer wall of the sliders via the guide rails, thus providing longitudinal sliding guidance for the pressure sleeve.

[0008] Preferably, the inner wall of the pressure block is provided with an anti-slip pad, and the outer wall of the tapered tube is fitted with a sealing gasket. The anti-slip pad increases the slip resistance between the pressure block and the outer wall of the condenser tube, and the sealing gasket ensures that the tapered tube fills the gap when it is connected to the inner wall of the condenser tube opening, thereby improving the sealing performance.

[0009] Preferably, the outer wall of the tapered tube is provided with equidistantly distributed positioning grooves, a sliding sleeve is embedded inside the pressure sleeve, a pull rod is slidably installed inside the sliding sleeve, a support block is provided at one end of the pull rod, and a locking tooth is provided at one end of the support block, which engages with the positioning groove. The locking tooth is located inside the groove at the corresponding position to prevent the spring from moving longitudinally.

[0010] Preferably, one end of the support block is provided with a second spring that connects to the inner wall of the pressure sleeve and is sleeved on the outside of the pull rod, and one end of the pull rod is provided with a handle. Gripping the handle facilitates the application of pulling force to the pull rod, and the second spring applies elastic support force to the locking teeth, which are inserted into the positioning tooth groove to position the pressure sleeve.

[0011] Preferably, a placement seat is fitted onto the lower outer wall of the distillation flask. The lower end of the placement seat is provided with support rods arranged in a circular array. A sleeve plate is provided at the lower end of each support rod, and the sleeve plate has screw holes inside. The placement seat supports the lower end of the distillation flask, and the support rods enable the sleeve plate to support the placement seat, thereby supporting the distillation flask.

[0012] Preferably, a base is provided below the sleeve plate, and a motor is provided at the upper end of the base. A screw is rotatably mounted inside a screw hole at the output end of the motor. A limit block is provided at the upper end of the screw. Through holes arranged in a circular array are embedded inside the sleeve plate. Guide rods arranged in a circular array and slidably mounted inside the through holes are provided at the upper end of the base. The motor drives the screw to rotate inside the screw hole and slides through the through hole via the guide rod, providing longitudinal sliding guidance for the sleeve plate. The screw pushes the sleeve plate to move longitudinally, and the limit block prevents the screw hole from completely disengaging from the screw, thus adjusting the height of the distillation flask.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model connects the distillation flask and condenser via a condenser tube and a steam tube. During the connection process, a conical tube is inserted into the condenser tube through the steam tube. The conical surface is adapted to the inner diameter of the condenser tube, and the gradually increasing outer diameter of the conical tube adapts to the needs of different condenser tube radii. Before and after the conical tube is inserted into the condenser tube, the pressure sleeve is gripped and relaxed. Through the elastic force of the spring, the pressure sleeve is pushed to compress the connecting rod, which is distributed in a ring and rotated and supported by the torsion spring. The connecting rod drives the pressure block to press against the outer wall of the condenser tube, fixing the conical tube inserted into the condenser tube, thereby fixing the condenser tube and the steam tube. This design is suitable for different models of distillation instruments, and the connection is convenient, improving the flexibility of use. Attached Figure Description

[0022] like Figures 1-5 As shown, the present invention proposes a glass distillation instrument, including a distillation flask 1, a sleeve 2, a steam pipe 5, a condenser pipe 6, a heat exchange shell 7, a pressure sleeve 15, a conical tube 23, and a pull rod 31.

A steam pipe 5 is provided at the upper end of the distillation flask 1, and a conical tube 23 is provided at the lower end of the steam pipe 5. A support ring 16 is sleeved on the outer wall of the steam pipe 5, and a spring 19 is provided at the lower end of the support ring 16. A pressure sleeve 15 is provided at the lower end of the spring 19. A bearing seat 20 arranged in a ring array is provided on the outer wall of the steam pipe 5. A rotating shaft 22 is rotatably installed inside the bearing seat 20. A connecting rod 25 is provided at one end of the rotating shaft 22, and a pressure block 26 is provided at the lower end of the connecting rod 25. A torsion spring 21 is sleeved on the outside of the rotating shaft 22, with its two ends connected to the bearing seat 20 and the connecting rod 25 respectively.

[0023] The lower end of the pressure sleeve 15 is rotatably installed with balls 35 arranged in a ring array, and the balls 35 roll and fit against the outer wall of the connecting rod 25.

[0024] The outer wall of the support ring 16 is provided with sliders 18 arranged in a ring array, and the upper end of the pressure sleeve 15 is provided with guide rails 17 arranged in a ring array and slidably installed inside the sliders 18.

[0025] The inner wall of the pressure block 26 is provided with an anti-slip pad 27, and the outer wall of the tapered tube 23 is fitted with a sealing gasket 24.

[0026] The outer wall of the tapered tube 23 is provided with equidistantly distributed positioning tooth grooves 28. A sliding sleeve 33 is embedded inside the pressure sleeve 15. A pull rod 31 is slidably installed inside the sliding sleeve 33. A support block 30 is provided at one end of the pull rod 31. A locking tooth 29 is provided at one end of the support block 30 and engages with the positioning tooth groove 28.

[0027] One end of the support block 30 is provided with a spring 32 that is connected to the inner wall of the pressure sleeve 15 and sleeved on the outside of the pull rod 31, and one end of the pull rod 31 is provided with a handle 34.

[0028] A placement seat 8 is fitted onto the lower outer wall of the distillation flask 1. A support rod 11 arranged in a circular array is provided at the lower end of the placement seat 8. A sleeve plate 2 is provided at the lower end of the support rod 11. A screw hole 12 is provided inside the sleeve plate 2.

[0029] A base 4 is provided below the sleeve plate 2, a motor 3 is provided on the upper end of the base 4, a screw 10 is provided at the output end of the motor 3 and is rotatably installed inside the screw hole 12, a limit block 14 is provided at the upper end of the screw 10, through holes 13 arranged in a ring array are embedded inside the sleeve plate 2, and guide rods 9 arranged in a ring array and slidably installed inside the through holes 13 are provided on the upper end of the base 4.

[0030] Based on the implementation steps of Example 1: The distillation flask 1 is placed on the placement seat 8. The motor 3 drives the screw 10 to rotate, achieving smooth lifting and lowering through the guidance of the sleeve 2 and guide rod 9. The docking height between the distillation flask 1 and the conical tube 23 is precisely adjusted. When the pressure sleeve 15 is lifted, the gripping lever 31 causes the locking teeth 29 to disengage from the corresponding positioning groove 28, and compresses the second spring 32. The first spring 19 is compressed, causing the guide rail 17 to slide on the outer wall of the slider 18, driving the pressure sleeve 15 to rise. Subsequently, the conical tube 23 is inserted into the upper opening of the condenser tube 6, connecting... The connecting rod 25 is rotated and supported by the rotating shaft 22. Under the elastic force of the torsion spring 21, it is released from compression when the pressure sleeve 15 is lifted. The pressure block 26 is separated from the outer wall of the condenser tube 6. Then the pressure sleeve 15 is relaxed. The ball bearing 35 inside the pressure sleeve 15 rolls and contacts the connecting rod 25, driving the rotating shaft 22 to move the pressure block 26 inward. When the cone tube 23 is inserted into the steam tube 5, the pressure sleeve 15 is released. The torsion spring 21 returns to its original position, so that the anti-slip pad 27 on the inner wall of the pressure block 26 is tightly attached to the outer wall of the cone tube 23. At the same time, the sealing gasket 24 forms a double seal.

[0031] Pulling the handle 34 causes the pull rod 31 to move outward, and the locking tooth 29 disengages from the positioning tooth groove 28. At this time, the cone tube 23 can be rotated to adjust the insertion depth. After releasing the handle 34, the spring 22 drives the locking tooth 29 to re-engage in the tooth groove to achieve positioning, preventing the pressure sleeve 15 from moving longitudinally at will, preventing the connecting rod 25 from rotating at will through the rotating shaft 22, and preventing the pressure block 26 from loosening. The condensation system is started, and steam enters the cone tube 23 through the steam pipe 5. The coolant continuously delivered by the heat exchange shell 7 achieves gas-liquid separation through heat exchange through the condenser pipe 6, and the distillate flows into the collection container along the pipe wall.

[0032] The lever-type pressure block 26 structure utilizes the pre-tightening force of the torsion spring 21 to facilitate the connection between the steam pipe 5 and the condenser pipe 6. After connection, the pressure block 26 clamps and fixes the outer wall of the condenser pipe 6 through the compression connecting rod 25. The ball bearing 35 design converts sliding friction into rolling friction, reducing the operating force of the pressure sleeve 15 and improving operational convenience. The annular array positioning tooth groove 28 engages with the locking teeth 29 to achieve clamping and fixing with different condenser pipes 6. Combined with the elastic deformation compensation of the anti-slip pad 27, the sealing of the steam passage is improved. The motor 3 drives the screw 10 to achieve... The stepless height adjustment and the 9-hole, 13-hole guide rod design eliminate lifting and lowering sway, solving the cumbersome problem of manual adjustment required by traditional supports. It also improves repeatability and positioning accuracy. Traditional glass distillation apparatuses are prone to leakage due to operational errors when manually sealed; this device achieves zero-leakage sealing through a mechanical self-locking structure. It overcomes the low efficiency and poor accuracy of manual height adjustment of the distillation flask, eliminates the risk of loosening and falling off of adjustment components in traditional instruments, and ensures stable equipment operation through mechanical interlocking design. It allows for compatibility with different models of distillation instruments, increasing flexibility and solving the problem of inconvenient rubber sleeve connection.
