Description

Technical Field

[0001] The utility model belongs to the technical field of fine chemical industry, and specifically relates to a reaction solvent drying and water removal device. Background Art

[0002] In chemical laboratories, many reaction tests need to be carried out in an environment without water or oxygen. Therefore, the reaction solvents required for the reaction tests need to be dried and dehydrated first.

[0003] In the prior art, when the reaction solvent is dried and dehydrated, it is placed in a distillation kettle for distillation, drying and dehydration. Although the existing distillation kettle can distill and remove the water in the reaction solvent, during the distillation and removal process, part of the water vapor distilled from the reaction liquid will adhere to the top of the kettle and condense into water droplets. When the water droplets are large enough, they will fall back into the reaction liquid, so that the excess water in the reaction liquid cannot be quickly precipitated, so a long drying and dehydration time is required. 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 reaction solvent drying and dewatering device which can overcome the above problems or at least partially solve the above problems.

[0007] In order to facilitate more convenient replacement of the breathable and water-absorbing layer, a thread groove is further provided at the middle position of the upper end of the arc-shaped filter plate, and the lower end of the transmission shaft is threadedly connected in the thread groove.

[0008] In order to ensure sufficient drainage, further, a circle of triangular drainage ring is fixedly connected to the outer side of the upper end of the arc-shaped filter plate, and the triangular drainage ring is slidably attached to the inner wall of the heating tank.

[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 3 The device for drying and removing water from a reaction solvent comprises a heating tank 1, on which a feed pipe 101 and a discharge pipe 102 are connected respectively, and a tank cover 2 is detachably connected to an opening at the upper end of the heating tank 1, and further comprises: an arc-shaped condensation shell 3, fixedly connected to the lower end of the tank cover 2; an inlet pipe 301 and an outlet pipe 302, symmetrically fixedly connected to both sides of the tank cover 2, and connected to a refrigeration cavity inside the arc-shaped condensation shell 3; a motor 201, fixedly connected to the upper end of the tank cover 2; a transmission shaft 202, fixedly connected to the input of the motor 201; a transmission shaft 203, fixedly connected to the output of the motor 203; a transmission shaft 204, fixedly connected to the output of the motor 203; a transmission shaft 205, fixedly connected to the output of the motor 203; a transmission shaft 206, fixedly connected to the output of the motor 203; a transmission shaft 207, fixedly connected to the output of the motor 203; a transmission shaft 208, fixedly connected to the output of the motor 203; a transmission shaft 209, fixedly connected to the output of the motor 203; a transmission shaft 209, fixedly connected to the output of the motor 203; a transmission shaft 201 ...1, fixedly connected to the output of the motor 203; a transmission shaft 208, fixedly connected to the output of the motor 203; a transmission shaft 209, fixedly connected to the output of the motor 203; a transmission shaft 209, fixedly connected to the outlet; an arc-shaped filter plate 4, which rotates in the heating tank 1 and is located below the arc-shaped condensing shell 3, with the outer side of the arc-shaped filter plate 4 slidingly attached to the inner wall of the heating tank 1, and the lower end of the transmission shaft 202 extending downward into the heating tank 1 and connected to the arc-shaped filter plate 4; a breathable water-absorbing layer 401, which is fixedly connected to the lower surface of the arc-shaped filter plate 4; a circle of conical water-collecting convex rings 103 is arranged inside the heating tank 1 near the bottom of the breathable water-absorbing layer 401; a drain pipe 107, which is connected to a position on the heating tank 1 near the conical water-collecting convex ring 103.

[0021] When it is necessary to remove the moisture contained in the reaction solvent, the staff will first transport the reaction solvent to be dehydrated into the heating tank 1 through the feed pipe 101, and then turn on the heating element set in the heating tank 1. Then the reaction solvent to be dehydrated will be heated and heated. When the temperature rises to the evaporation temperature of the water in the reaction solvent, the water in the reaction solvent will float upward in the form of water vapor, and then cooling water can be transported to the arc-shaped condensation shell 3 through the water inlet pipe 301. After the arc-shaped condensation shell 3 is filled with cooling water, excess water will flow out through the water outlet pipe 302. By continuously transporting cooling water to the arc-shaped condensation shell 3, the surface of the arc-shaped condensation shell 3 can be kept at a relatively low temperature. When the water vapor floats upward through the breathable water-absorbing layer 401 and the arc-shaped filter plate 4 and contacts the arc-shaped condensation shell 3, the water vapor with a higher temperature will quickly reduce the temperature under the action of the arc-shaped condensation shell 3, thereby condensing into Water droplets are attached to the arc-shaped condensation shell 3. When there are more water droplets attached to the arc-shaped condensation shell 3, the water droplets will fall onto the arc-shaped filter plate 4 under the action of their own gravity, and fall into the breathable water-absorbing layer 401 through the filter holes on the arc-shaped filter plate 4, and absorb the breathable water-absorbing layer 401. As the amount of water absorbed in the breathable water-absorbing layer 401 continues to increase, the motor 201 can be started at this time, and the motor 201 will drive the arc-shaped filter plate 4 and the breathable water-absorbing layer 401 to rotate rapidly through the transmission shaft 202. Then, the water in the breathable water-absorbing layer 401 will be thrown out of the breathable water-absorbing layer 401 under the action of centrifugal force, and the thrown-out water will be collected in the water collecting trough formed by the conical water-collecting convex ring 103 and the heating tank 1, and discharged from the heating tank 1 through the drain pipe 107. Compared with the method of directly heating and drying the reaction solvent to remove water in the prior art, the reflux amount of water droplets can be effectively reduced, and the efficiency and quality of drying and removing water from the reaction solvent can be effectively improved.

[0022] Embodiment 2:

[0023] Reference Figure 1-Figure 3, a reaction solvent drying and dewatering device is basically the same as that of Example 1, and furthermore: a heat preservation cavity 104 is opened inside the conical water collecting convex ring 103, and a liquid inlet pipe 105 and a liquid outlet pipe 106 connected to the heat preservation cavity 104 are installed on the heating tank 1, the liquid inlet pipe 105 is arranged at the lower end of the heat preservation cavity 104, and the liquid outlet pipe 106 is arranged at the upper end of the heat preservation cavity 104. By opening the heat preservation cavity 104 in the conical water collecting convex ring 103, when the water in the reaction solvent is separated from the reaction solvent in the form of water vapor and floats upward, this At this time, the high-temperature medium can be transported into the heat-insulating cavity 104 through the liquid inlet pipe 105 and flow out through the liquid outlet pipe 106, so that the conical water-collecting convex ring 103 can always maintain a high temperature under the action of the circulating flow of the high-temperature medium, thereby avoiding that when the water vapor contacts the conical water-collecting convex ring 103, part of the water vapor is liquefied due to the low temperature, and then turns back into water and flows back into the reaction solvent, thereby increasing the dehydration time of the reaction solvent, and effectively reducing the amount of water vapor that turns into water droplets when it contacts the conical water-collecting convex ring 103, thereby reducing the dehydration time.

[0024] Embodiment 3:

[0025] Reference Figure 1-Figure 3 , a reaction solvent drying and dewatering device is basically the same as Example 2, and further: a thread groove is provided in the middle position of the upper end of the arc filter plate 4, and the lower end of the transmission shaft 202 is threadedly connected in the thread groove, and the transmission shaft 202 and the arc filter plate 4 are detachably connected through threads. When the transmission shaft 202 drives the arc filter plate 4 to rotate, the arc filter plate 4 can be driven to rotate in the opposite direction of the threads, thereby avoiding the arc filter plate 4 from being separated from the transmission shaft 202. When it is necessary to regularly replace the breathable and water-absorbing layer 401, the tank cover 2 can be opened at this time, and the breathable and water-absorbing layer 401 can be taken out of the heating tank 1 through the arc filter plate 4, and then the arc filter plate 4 can be rotated to remove the arc filter plate 4 together with the breathable and water-absorbing layer 401 from the transmission shaft 202, and then it can be replaced.

[0026] A circle of triangular drainage ring 402 is fixedly connected to the outer side of the upper end of the arc filter plate 4, and the triangular drainage ring 402 slides against the inner wall of the heating tank 1. Through the setting of the triangular drainage ring 402, when the transmission shaft 202 drives the arc filter plate 4 to rotate rapidly, part of the water droplets falling from the arc condensation shell 3 will be thrown onto the inner wall of the heating tank 1 under the action of centrifugal force, so that these water droplets can be collected and discharged. When the rotation speed of the arc filter plate 4 decreases, these water droplets will flow back to the arc filter plate 4 along the triangular drainage ring 402 again, and then they can fall onto the breathable water absorption layer 401 through the filter holes on the arc filter plate 4 and be absorbed by the breathable water absorption layer 401. When the arc filter plate 4 rotates rapidly again, the water absorbed by the breathable water absorption layer 401 will be thrown into the conical water collection convex ring 103 under the action of centrifugal force, so that they can be discharged through the drain pipe 107, effectively ensuring the adequacy of drainage.

[0027] The breathable water-absorbing layer 401 is a high-temperature resistant water-absorbing sponge. By making the breathable water-absorbing layer 401 of a high-temperature resistant water-absorbing sponge, the high-temperature resistance of the breathable water-absorbing layer 401 can be improved while ensuring water absorption, thereby effectively increasing the service life of the breathable water-absorbing layer 401.

[0028] An observation window 108 is provided on the heating tank 1 below the conical water collecting convex ring 103. Through the setting of the observation window 108, the staff can start the motor 201 and transport the refrigeration and insulation medium to the arc-shaped condensation shell 3 and the insulation cavity 104 by checking whether the reaction solvent inside the heating tank 1 generates water vapor. There is no need to start the entire device at the beginning, which effectively saves the use cost.

[0029] 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.
