Description

Technical Field

[0001] The utility model belongs to the technical field of laboratory appliances, and in particular relates to a multi-stage water separator for laboratories. Background Art

[0002] The water separator is mainly used to separate the water generated by chemical reactions in chemical experiments. The presence of water in the reaction system during the experiment may have a certain impact on the reaction or prevent the reaction from proceeding forward. In the prior art, in order to facilitate the removal of water in the reaction solvent, the water separator is usually connected to a reaction bottle with the reaction solvent, and then the reaction bottle is heated to remove the water through the solvent that is azeotropic with water. Then, the steam generated by boiling is condensed, and then the density difference between the solvent and water is used to separate the layers, so that the water in the lower layer can be discharged, and the solvent in the upper layer will flow back into the reaction bottle to continue the reaction and remove water. This process is repeated to fully discharge the water in the solvent.

[0003] However, the existing water separators often have some problems when in use. Since the condensed solvent is only separated once, the water content of the solvent flowing back into the reaction bottle is still relatively large, and the water separation effect is not good. Therefore, it takes a long time to complete the sufficient water removal process, and the water removal efficiency needs to be further improved. In view of this, the present utility model is specially proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a laboratory multi-stage water separator which can overcome the above problems or at least partially solve the above problems.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is: a multi-stage water separator for laboratory use, comprising: a steam ascending pipe, the air inlet end of the steam ascending pipe is sealed and inserted in the air outlet port of the reaction bottle; a liquid separator tube 1, fixedly connected to the air outlet end of the steam ascending pipe, the air outlet at the upper end of the liquid separator tube 1 is connected to the air inlet of the external condenser; a liquid separator tube 2, fixedly connected to the lower end of the tube body of the steam ascending pipe; valve 1 and valve 2 are respectively installed at the liquid outlets of the liquid separator tube 1 and the liquid separator tube 2.

[0006] In order to facilitate the splashing droplets to flow back into the reaction bottle, further, a drainage plate is fixedly connected to one side of the inner part of the liquid separation tube close to the steam ascending pipe, and the drainage plate is higher than the steam ascending pipe.

[0007] In order to prevent the liquid that has not yet been stratified from following the solvent back to the reaction bottle, further, a partition is fixedly connected to the separatory tube below the drainage plate, and the upper end of the partition is higher than the outlet of the steam ascending pipe.

[0008] In order to improve the sealing performance among the steam ascending pipe, the first liquid distributing pipe and the second liquid distributing pipe, the steam ascending pipe, the first liquid distributing pipe and the second liquid distributing pipe are further integrally formed.

[0009] In order to facilitate the heat preservation of the steam, a heat preservation sleeve is further provided on the steam ascending pipe.

[0010] Furthermore, the thermal insulation sleeve is respectively connected with a liquid inlet pipe and a liquid outlet pipe, the liquid inlet pipe is arranged at the lower end of the thermal insulation sleeve, and the liquid outlet pipe is arranged at the upper end of the thermal insulation sleeve.

[0011] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: the utility model has a simple design, is easy to manufacture and has a low cost, which is conducive to popularization and use. By increasing the number of liquid separation tubes, it is equivalent to multiple water separations, which reduces the water content of the solvent flowing back into the reaction bottle, improves the water removal efficiency, and correspondingly improves the reaction efficiency, saves time costs, and is very suitable for laboratory use.

[0012] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0019] Embodiment 1:

[0020] Reference Figure 1-Figure 3A multi-stage water separator for laboratory use comprises: a steam ascending pipe 1, the air inlet end of the steam ascending pipe 1 is sealed and inserted into the air outlet port of a reaction bottle; a liquid separator 2 is fixedly connected to the air outlet end of the steam ascending pipe 1, and the air outlet at the upper end of the liquid separator 2 is connected to the air inlet of an external condenser; a liquid separator 2 3 is fixedly connected to the lower end of the pipe body of the steam ascending pipe 1; valves 1 201 and 2 301 are respectively installed at the liquid outlets of the liquid separator 1 2 and the liquid separator 2 3.

[0021] In the process of conducting chemical experiments, in order to facilitate the discharge of moisture in the solvent, the experimenter can first plug the air inlet end of the steam ascending pipe 1 into the mouth of the reaction bottle containing the solvent through a seal, and then connect the air outlet end of the upper end of the separatory tube 2 to the external condenser. Then the experimenter can heat the reaction bottle through a heating device, so as to distill the mixture of solvent and water in the reaction bottle. When the solvent and water boil, the solvent and water will generate steam and float upward into the steam ascending pipe 1, and then the steam will enter the separatory tube 2 through the steam ascending pipe 1, and then continue to float upward into the condenser, and then the condenser will condense the steam, and then the solution condensed by the condenser will return to the separatory tube 2 for storage under the action of gravity, and the density difference between the organic solvent and water will be used to separate the layers, and the condensed solvent and water mixture will be stored in the separatory tube 2. The liquid in the separatory tube 2 is layered so that the water is located in the lower layer and the solvent is located in the upper layer. Then, valve 201 is opened, and the water in the separatory tube 2 can discharge the water in the lower layer, thereby completing one water separation. As the amount of solvent in the separatory tube 2 increases, when the organic solvent submerges the air inlet, the solvent will reflux into the steam ascending pipe 1, and then the solvent will enter the separatory tube 2 3. Since there may still be some water in the solvent after one water separation, the solvent and water will be layered again in the separatory tube 2 3. When a certain amount of water is stored in the separatory tube 2 3, valve 2 301 can be opened at this time, and the water in the separatory tube 2 3 can be discharged. As the height of the solvent in the separatory tube 2 3 continues to rise, when it is higher than the liquid inlet, the solvent after multiple levels of water separation will reflux along the steam ascending pipe 1 into the solvent in the reaction bottle for re-distillation. After multiple treatments, the removal of water from the solvent can be completed.

[0022] It should be noted that, in order to improve the efficiency of water separation from the solvent, a plurality of liquid separation pipes can be sequentially arranged on the steam ascending pipe 1, thereby further improving the efficiency of water separation from the solvent.

[0023] Embodiment 2:

[0024] Reference Figure 1-Figure 3, a multi-stage water separator for laboratory use, is basically the same as Example 1, and further: a drainage plate 202 is fixedly connected to the side of the liquid separation tube 2 close to the steam ascending pipe 1, and the drainage plate 202 is higher than the steam ascending pipe 1.

[0025] A partition plate 203 is fixedly connected to the liquid separation pipe 2 below the guide plate 202, and the upper end of the partition plate 203 is higher than the outlet of the steam ascending pipe 1.

[0026] When the steam enters the condenser through the separatory tube 2 for condensation, the condensed liquid will freely fall back into the separatory tube 2. The drainage plate 202 can be used to drain the liquid and make it flow to the side of the partition 203 in the separatory tube 2 away from the steam ascending tube 1, so as to prevent the splashing droplets from entering the steam ascending tube 1 when the solution drips into the solution stored in the separatory tube 2, so that the water in the droplets flows back into the reaction bottle again, effectively improving the water separation effect and efficiency. The partition 203 can also separate the liquid that has not yet been stratified from the solvent in the upper layer of the separatory tube 2, so as to prevent the liquid that has not yet been stratified from following the solvent back to the reaction bottle, further improving the water separation effect and efficiency.

[0027] Embodiment 3:

[0028] Reference Figure 1-Figure 3 A multi-stage water separator for laboratory use is basically the same as Example 2, and furthermore: the steam ascending pipe 1, the liquid distributing pipe 1 2, and the liquid distributing pipe 2 3 are integrally formed.

[0029] By integrally molding the steam ascending pipe 1, the liquid distributing pipe 1 2, and the liquid distributing pipe 2 3, not only can the sealing between the steam ascending pipe 1, the liquid distributing pipe 1 2, and the liquid distributing pipe 2 3 be ensured, but also the service life of the water distributor can be improved.

[0030] Embodiment 4:

[0031] Reference Figure 1-Figure 3 , a multi-stage water separator for laboratory use, which is basically the same as Example 3, and further: a heat preservation sleeve 101 is provided on the steam ascending pipe 1.

[0032] The insulation sleeve 101 is connected to a liquid inlet pipe 1011 and a liquid outlet pipe 1012 , respectively. The liquid inlet pipe 1011 is arranged at the lower end of the insulation sleeve 101 , and the liquid outlet pipe 1012 is arranged at the upper end of the insulation sleeve 101 .

[0033] When it is necessary to insulate the steam, the external conveying equipment can be started to convey the insulating fluid medium, such as water, oil, etc., into the insulating sleeve 101 through the liquid inlet pipe 1011. When the insulating sleeve 101 is full of the insulating fluid medium, the insulating fluid medium will be discharged through the liquid outlet pipe 1012 and flow back into the insulating fluid medium storage and heating box, so that the steam can be continuously insulated to prevent the gas from condensing prematurely, effectively improving the water separation effect and efficiency.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
