Description

Technical Field

[0002] In the field of chemical experiments, low-temperature reactions involving ozone require multiple functional modules such as ozone generation, low-temperature control, and stirring and mixing. In existing experimental setups, these modules are mostly independent devices, such as oxygen cylinders placed separately, stirring devices separated from reaction vessels, and low-temperature control requiring additional condensation equipment. This decentralized layout not only occupies a lot of experimental space, but also requires connecting various devices through complex pipelines, resulting in cumbersome experimental operations and a risk of leakage at pipeline connections.

[0003] Meanwhile, traditional stirring devices often use direct mechanical transmission, and their sealing structure is prone to failure in low-temperature environments, affecting reaction stability. Oxygen cylinders lack dedicated fixing mechanisms, posing a risk of tipping over. Furthermore, it is difficult to monitor the temperature and reaction status in real time during the reaction process, further increasing experimental errors.

[0004] Therefore, in order to meet the laboratory's requirements for efficient, safe and precise low-temperature ozone reactions, there is an urgent need for an integrated experimental device that can organically integrate various functional modules, simplify the operation process and improve experimental reliability.

A hemispherical placement groove 317 is provided above the flask stand. A plurality of placement pads 311 are provided inside the placement groove 317. The placement groove 317 is used to place a three-necked flask 5. The placement pads 311 are arranged between the placement groove 317 and the three-necked flask 5.

[0039] The flask holder has a filling cavity 309 inside, which is used to fill condensate. The condensate is used to lower the temperature at the bottom of the three-necked flask 5.

[0041] In the preferred embodiment, one side of the stirring shell 301 is provided with an air inlet pipe 305 and the other side is provided with an air outlet pipe 306.

The temperature probe 315 is used to measure the temperature in the three-necked flask 5.

[0044] The operating steps of a low-temperature ozone reaction device are as follows: Open the sealing door 302 of the stirring assembly 3, grasp the handle 304 and pull it outwards to place the three-necked flask 5 into the hemispherical placement groove 317 located below the stirring housing 301. During placement, the multiple placement pads 311 between the bottom of the three-necked flask 5 and the placement groove 317 are in close contact, providing a buffering and shock-absorbing effect. Start the condensation device connected to the filling cavity 309 of the flask holder to initiate the condensation cycle, lowering the temperature at the bottom of the three-necked flask 5 and providing an environment for the low-temperature reaction.

[0045] The left opening of the three-necked flask 5 is connected to one end of the flexible tube 313 via the connecting plug 314, and the connecting flange 312 at the other end of the flexible tube 313 is connected to the output end of the ozone generator 318. The right opening is also connected to the gas outlet pipe 306 on one side of the stirring shell 301 via the connecting plug 314, the flexible tube 313 and the connecting flange 312 to form an ozone circulation path. A detachable temperature probe 315 is inserted into the top opening of the three-necked flask 5, and the probe is fixed to the top of the stirring shell 301 by the flexible rod 316 to ensure that the probe is completely immersed in the reaction liquid.

[0046] During the initial installation of oxygen cylinder 4, first loosen the bolts in the tension hole 202 of the mounting bracket 2, and slide the outer pressure plate 204 outward along the guide rod in the guide hole 206 to remove it. Push oxygen cylinder 4 along the guide plates 208 on both sides of the bottom bracket 207 between the inner bracket 201 and the bottom bracket 207, so that the bottom of oxygen cylinder 4 rests completely on the bottom bracket 207. Then, align the guide hole 206 of the outer pressure plate 204 with the guide rod and reset it, so that the inner groove 203 of the inner bracket 201 and the outer groove 203 of the outer pressure plate 204 fit against the outer wall of oxygen cylinder 4, and tighten the bolts in the tension hole 202 until oxygen cylinder 4 is firmly clamped. Finally, connect the output pipe of oxygen cylinder 4 to the inlet pipe 305 of ozone generator 318 to complete the preliminary preparation.

[0047] Confirm that the base frame 101 of the frame 1 is placed stably and that the shock-absorbing feet 103 are in close contact with the ground (the height can be adjusted by rotating the feet to reduce vibration during equipment operation); that all components of the stirring assembly 3 in the top frame 102 are connected correctly; and that after the sealing door 302 is closed, observe through the transparent viewing window 303 whether the three-necked flask 5 is placed firmly and whether the temperature probe 315 is properly positioned.

[0048] Equipment startup and reaction proceeding

[0049] Start the stirring motor 307 of the stirring assembly 3. The motor output shaft drives the disk 308 to rotate. The permanent magnet on the top of the disk 308 rotates. Since the stir bar 310 inside the three-necked flask 5 has a built-in permanent magnet, it rotates synchronously with the disk 308 under the action of the magnetic field, so as to achieve uniform stirring of the reaction liquid in the three-necked flask 5.

[0050] When the valve of oxygen cylinder 4 is opened, oxygen enters the ozone generator 318 inside the stirring assembly 3 via pipeline. The generated ozone enters the flexible tube 313 through the inlet pipe 305, and then enters the three-necked flask 5 through the connecting plug 314 to contact the reaction liquid, resulting in a low-temperature ozone reaction. The waste gas generated during the reaction enters the outlet pipe 306 through the right opening of the three-necked flask 5 and the flexible tube 313, and is finally discharged to the waste gas treatment system.

[0051] The temperature probe 315 monitors the temperature of the reaction solution in real time. The experimenter can observe the reaction status, such as the amount of bubbles and changes in solution color, through the viewing window 303. The reaction process can be controlled by adjusting the temperature of the condensate or the amount of ozone introduced.

That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
