Abstract
Description
Technical Field
[0001] This utility model relates to the field of vapor permeation technology, specifically to a vapor permeation inorganic membrane vacuum pumping assembly. Background Technology
[0002] The pervaporation inorganic membrane uses molecular sieves as the membrane material, utilizing their regular channels to achieve separation of different components by molecular size. During the dehydration process of the pervaporation inorganic membrane, the aqueous mixed organic solvent is preheated and then enters the feed side of the membrane module, while the permeate side is maintained in a low-pressure environment (absolute pressure below 2000 Pa) by vacuuming. On the feed side, water molecules preferentially adsorb onto the membrane surface and permeate through the membrane under the pressure difference of water vapor on both sides, vaporizing into water vapor on the permeate side. After separation, the feed side outlet of the membrane yields anhydrous organic solvent product, while the permeate side components are condensed and sent to wastewater treatment.
[0003] The patent application CN104262089B discloses a method and apparatus for dehydrating and refining biofuels. In this method, the permeate side of the vapor permeate membrane separator is connected to the permeate condenser via a permeate output pipe, and finally the permeate is introduced into a permeate tank. The permeate tank is connected to a vacuum pump. According to this technical solution, the vacuum pump can be used to evacuate the vapor permeate inorganic membrane separator so that water molecules in the water-containing organic solvent can enter the permeate side and then be collected by condensation through the condenser.
[0004] The applicant discovered that after a vacuum pump has been working for a long time, the pump body and motor will generate a certain amount of heat. Authorized publication number CN213627907U discloses a vacuum pump with a heat dissipation function, which has a heat dissipation mechanism at the top of the vacuum pump body. This mechanism includes a heat dissipation shell, with five sets of air vents extending through the top of the shell. Each air vent is equipped with a fan. When the user uses the device, the fan starts, generating airflow at its bottom. This airflow circulates the air around the vacuum pump body, carrying away heat and improving the cooling effect. This enhances the heat dissipation efficiency of the vacuum pump body, reduces wear and tear, and extends its service life.
[0005] However, the applicant found that the wind from above was not strong enough to blow on the bottom area of the vacuum pump body, resulting in low efficiency in cooling the vacuum pump. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] See Figures 1-4 This utility model provides the following two technical solutions:
[0025] The first embodiment: A vapor permeation inorganic membrane vacuum pumping assembly includes a motor 1, a bearing housing 2, and a vacuum pump body 3. The output shaft of the motor 1 is connected to the impeller inside the bearing housing 2 and the vacuum pump body 3. The vacuum pump body 3 is provided with an inlet and an outlet. The inlet is connected to the permeate tank, the permeate tank is connected to the condenser, and the condenser is connected to the permeate side of the vapor permeation inorganic membrane separator. The motor 1, the bearing housing 2, and the vacuum pump body 3 are all connected to the base 4. Support rods 5 are provided around the bottom of the base 4, and the bottom of the support rods 5 are all connected to the base 6.
[0026] A housing 7 is attached to the outer side of the base 4, and a lifting assembly is provided at the bottom of the housing 7. Heat-conducting baffles 11 are attached to both sides of the inner wall of the housing 7, and the heat-conducting baffles 11 are set on the base 4. The two heat-conducting baffles 11 are attached to the motor 1 and the vacuum pump body 3 respectively, which can divide the motor 1, bearing seat 2 and vacuum pump body 3 into three areas. Several ventilation holes 12 are opened at the bottom of the base 4 between the two heat-conducting baffles 11. Fan assemblies 2 are provided on both sides of the housing 7. The two fan assemblies 2 on both sides are connected to fan assembly 1, and fan assembly 1 is connected to the ventilation holes 12, which can blow air to the three areas, so that the airflow does not affect each other and ensures the heat dissipation efficiency of the motor 1, bearing seat 2 and vacuum pump body 3.
[0027] The lifting assembly includes support frames 8 on both sides of the bottom of the housing 7. The bottom of the support frames 8 is mounted on a movable plate 9. The movable plate 9 is connected to an electric guide rail 10 mounted on the base 6. The electric guide rail 10 is powered and controlled by existing technology, which can drive the movable plate 9 to rise and fall. This causes the support frames 8 to drive the housing 7 to rise and fall, allowing the housing 7 to move downward on the base 4 and expose the base 4. This facilitates regular inspection and maintenance of the motor 1, bearing housing 2, or vacuum pump body 3. To facilitate the raising and lowering of the movable plate 9, a guide rod 22 is provided at the top of the base 6, penetrating the movable plate 9. The bottom of the support rods 5 all penetrate the movable plate 9, allowing the movable plate 9 to move on the support rods 5 when it moves downward.
[0028] The fan assembly includes a filter cover 15 that is attached to the bottom of the base 4. The support frame 8 is connected to the filter cover 15, so that the housing 7 and the filter cover 15 are fixedly connected. The top of the filter cover 15 is connected to the ventilation hole 12. The filter cover 15 is connected to the fan 14 through the bearing. The fan 14 is connected to the output shaft of the drive motor 13 set on the movable plate 9. The drive motor 13 is powered and controlled by existing technology. By driving the fan 14 to rotate, the airflow enters between the two heat-conducting partitions 11 through the ventilation hole 12.
[0029] The second fan assembly includes two filter covers 16, which pass through both sides of the housing 7. The filter covers 16 are connected to the second fan 17 via bearings. A rotating shaft 18 is connected to the support frame 8 via bearings. A belt drive assembly 19 is connected between the rotating shaft 18 and the second fan 17. A driven bevel gear 20 is provided on the rotating shaft 18. An active bevel gear 21 is provided on the output shaft of the drive motor 13 and meshes with the driven bevel gear 20. The active bevel gear 21 drives the driven bevel gear 20 to rotate, so that the rotating shaft 18 drives the second fan 17 to rotate under the action of the belt drive assembly 19. The two fans 17 blow air to the opposite side, which can blow air to the motor 1 and the vacuum pump body 3 respectively. The airflow is finally blocked by the heat-conducting baffle 11.
[0030] The second embodiment differs from the first embodiment in that the heat-conducting partition 11 has grooves 23 evenly distributed on both sides.
[0031] The heat-conducting baffle 11 is made of copper-aluminum alloy material, which can conduct heat from the motor 1 and the vacuum pump body 3, thereby helping to dissipate heat when it is acted upon by airflow. In addition, the groove 23 also increases the contact area with air, which further facilitates heat dissipation.
[0032] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.
[0033] In use, fan 14 is turned on, causing fan 2 17 to rotate synchronously. Fan 14 draws air from the bottom and delivers it upwards, allowing the airflow to enter between the heat-conducting baffles 11 on both sides through the ventilation holes 12. This cools the opposite sides of the motor 1 and the vacuum pump body 3, as well as the bearing housing 2. Fan 2 17 blows air onto the motor 1 and the vacuum pump body 3, cooling the sides of the motor 1 and the vacuum pump body 3 that are far apart from each other, and also cooling the outer ring of the motor 1 and the vacuum pump body 3. The airflow from fan 2 17 is ultimately blocked by the heat-conducting baffles 11, ensuring that the airflow in the three directions does not interfere with each other, thus achieving comprehensive and rapid heat dissipation for the motor 1, the bearing housing 2, and the vacuum pump body 3.
