Description

Technical Field

[0001] This utility model belongs to the field of microporous membrane production technology, and specifically relates to a drying device for microporous membrane production. Background Technology

[0002] Microporous membranes are made by coating a support layer with specially treated polymeric chemical materials and pore-forming additives. In membrane separation technology, microporous membranes are the most widely used type of membrane. They are simple and quick to use and are widely applied in scientific research, food testing, chemical engineering, nanotechnology, energy, and environmental protection, among many other fields. Drying is necessary during the production of microporous membranes (drying can accelerate the structural shaping of the microporous membrane).

[0003] In the current technology, when drying microporous filter membranes, hot air is blown directly onto the microporous filter membrane by a hot air blower. However, direct airflow can easily cause physical damage to the surface of the microporous filter membrane, affecting its appearance. Therefore, a technical measure is proposed to solve the problem that in the current technology, when drying microporous filter membranes, hot air blown directly onto the microporous filter membrane by a hot air blower can easily cause physical damage to the surface of the microporous filter membrane, affecting its appearance. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a drying device for microporous membrane production, which aims to solve the problem that in the prior art, when drying microporous filter membranes, hot air blown directly onto the microporous filter membrane by a hot air blower can easily cause physical damage to the surface of the microporous filter membrane and affect the appearance of the membrane.

[0006] (2) Technical solution

[0007] To address the aforementioned technical problems, this utility model provides a drying device for microporous membrane production, comprising a workbench with an mounting frame installed in the middle of its upper surface. Two sets of symmetrically distributed drying components are installed within the mounting frame. Two sets of symmetrically distributed blocking components are also installed on the upper surface of the workbench, located on either side of the mounting frame. Two sets of symmetrically distributed slots are formed on the upper surface of the workbench, directly below the blocking components. Thanks to the drying components, the air inside the mounting frame is heated to the required drying temperature. The hot air does not directly blow onto the microporous membrane, thus preventing physical damage to the membrane surface and ensuring the membrane's appearance integrity.

[0008] Furthermore, a base frame is installed on the lower part of the workbench.

[0009] Furthermore, two sets of vertical plates are installed at both ends of the upper surface of the workbench. A first motor is installed on the upper side of one set of vertical plates. The first motor is connected to a take-up roller, and the take-up roller is rotatably connected to the vertical plate.

[0010] Furthermore, a guide roller is installed on the upper side of one of the vertical plates, and a limiting disc is provided on the winding roller.

[0011] Furthermore, the drying assembly includes a drying plate, and there are two sets of drying plates. The two sets of drying plates are symmetrically installed inside the mounting frame. Multiple sets of evenly distributed electric heating rods are installed through the side of the drying plate, and a water inlet pipe is installed through the middle of the side of the drying plate.

[0012] Furthermore, the water inlet pipe is L-shaped, a cover is movably installed on the upper part of the water inlet pipe, and a thermometer is installed through the water inlet pipe.

[0013] Furthermore, the blocking component includes a frame, of which there are two sets. The two sets of frames are fixedly installed on the upper surface of the workbench. A second motor is installed on the upper surface of the frame. A sliding groove is opened inside the frame. The motor is connected to a bidirectional screw. The bidirectional screw is threadedly connected to two sets of moving blocks. Two sets of sealing plates are connected to the sides of the moving blocks. Thanks to the setting of the blocking component, it is convenient to seal the mounting frame, which greatly reduces the energy loss inside the mounting frame, thereby ensuring that the temperature inside the mounting frame is always matched with the temperature of the microporous filter membrane drying.

[0014] Furthermore, the movable block is slidably adapted to the slide groove, a set of the sealing plates is slidably adapted to the slot, and a set of the sealing plates is slidably adapted to the frame.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes a drying assembly to heat the air inside the mounting frame, ensuring it reaches the drying temperature. The hot air does not directly blow onto the microporous filter membrane, preventing physical damage to its surface and preserving its appearance. Heat-conducting oil is injected into the inlet pipe after opening the cover, and then the electric heating rod is activated to heat the oil. The temperature of the oil is monitored using a thermometer. Once the drying temperature is reached, the power of the electric heating rod remains constant. The drying plate heats the interior of the mounting frame until it reaches the drying temperature. After the drying assembly operates for a period of time, the interior of the mounting frame reaches the drying temperature, allowing the microporous filter membrane to dry as it passes through.

[0018] By setting up the blocking components, it is easy to seal the mounting frame, which greatly reduces the energy loss inside the mounting frame, thereby ensuring that the temperature inside the mounting frame is always matched with the drying temperature of the microporous filter membrane. The second motor starts and drives the sealing plates to move closer to each other. When the gap between the two sets of sealing plates matches the microporous filter membrane, the second motor is turned off. Attached Figure Description

[0025] 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.

[0026] This specific embodiment is a drying device for microporous membrane production, and its structural schematic diagram is shown below. Figure 1 , Figure 2 , Figure 3As shown, the system includes a workbench 1, with a mounting frame 10 installed at the center of the upper surface of the workbench 1. Two symmetrically distributed drying components 2 are installed inside the mounting frame 10. Two symmetrically distributed blocking components 3 are installed on the upper surface of the workbench 1, with the blocking components 3 located on both sides of the mounting frame 10. Two symmetrically distributed slots 11 are formed on the upper surface of the workbench 1, directly below the blocking components 3. A base frame 4 is installed at the bottom of the workbench 1. Two sets of vertical plates 5 are installed at both ends of the upper surface of the workbench 1. A first motor 6 is installed on the upper side of one set of vertical plates 5, and the first motor 6 is connected to a take-up roller 7. 7 is rotatably connected to the vertical plate 5. A guide roller 8 is installed on the upper side of one set of vertical plates 5. A limiting plate 9 is provided on the winding roller 7. The drying assembly 2 includes a drying plate 201. There are two sets of drying plates 201, which are symmetrically installed inside the mounting frame 10. Multiple sets of evenly distributed electric heating rods 202 are installed through the side of the drying plate 201. A water inlet pipe 203 is installed through the middle of the side of the drying plate 201. The water inlet pipe 203 is L-shaped. A cover 205 is movably installed on the upper part of the water inlet pipe 203. A thermometer 204 is installed through the water inlet pipe 203. In actual operation, the microporous filter membrane is subjected to... During the drying process, the microporous filter membrane is passed through the guide roller 8, mounting frame 10, and blocking assembly 3. The microporous filter membrane is then fixed onto the take-up roller 7, and the limiting plate 9 limits its position. The blocking assembly 3 is then activated, sealing both ends of the mounting frame 10 (the blocking assembly 3 and the interior of the mounting frame 10 can be coated with a heat-insulating coating, such as alumina or zirconium oxide). The drying assembly 2 is then activated for drying. Finally, the motor is started to slowly rotate the take-up roller 7, which moves the microporous filter membrane through the interior of the mounting frame 10, opening the cover 205. Heat transfer oil is injected into the water inlet pipe 203, and then the electric heating rod 202 is started to heat the heat transfer oil. The temperature of the heat transfer oil is observed through the thermometer 204. When the drying temperature is reached, the power of the electric heating rod 202 is kept constant. The drying plate 201 heats the temperature inside the mounting frame 10 so that the temperature inside the mounting frame 10 reaches the drying temperature (for example, the drying temperature of a common nylon microporous filter membrane can generally be controlled at 80-100℃). After the drying component 2 has been working for a period of time, the temperature inside the mounting frame 10 reaches the drying temperature. The microporous filter membrane is dried when it passes through.

[0027] Reference Figure 1 , Figure 2 , Figure 4As shown, the blocking component 3 includes a frame 301, of which there are two sets. The two sets of frames 301 are fixedly installed on the upper surface of the workbench 1. A second motor 302 is installed on the upper surface of the frame 301. A sliding groove 305 is opened inside the frame 301. The motor is connected to a bidirectional screw 306. The bidirectional screw 306 is threadedly connected to two sets of moving blocks 304. Two sets of sealing plates 303 are connected to the sides of the moving blocks 304. The moving blocks 304 are slidably adapted to the sliding groove 305. One set of sealing plates 303 is slidably adapted to the slot 11. The other set of sealing plates 303 is slidably adapted to the frame 301. When the second motor 302 is started, it drives the bidirectional screw 306 to rotate. The rotation of the bidirectional screw 306 drives the moving blocks 304 to move closer to each other along the sliding groove 305. The moving blocks 304 moving closer to each other drive the sealing plates 303 to move closer to each other. When the gap between the two sets of sealing plates 303 is adapted to the microporous filter membrane, the second motor 302 is turned off.

[0028] Working principle: When drying the microporous filter membrane, the microporous filter membrane is passed through the guide roller 8, the mounting frame 10, and the blocking component 3. Then, the microporous filter membrane is fixed on the take-up roller 7. The microporous filter membrane is limited by the limiting plate 9. Then, the blocking component 3 is activated, so that the blocking component 3 completes the sealing of both ends of the mounting frame 10 (the blocking component 3 and the inside of the mounting frame 10 can be coated with a heat insulation coating, such as alumina or zirconium oxide coating). Then, the drying component 2 is activated for drying. Then, the motor is started to drive the take-up roller 7 to rotate slowly. The slow rotation of the take-up roller 7 drives the microporous filter membrane to move through the inside of the mounting frame 10.

[0029] The specific working method of the drying component 2 is as follows: heat transfer oil is injected into the water inlet pipe 203 by opening the cover 205, and then the electric heating rod 202 is started to heat the heat transfer oil. The temperature of the heat transfer oil is observed by the thermometer 204. When the drying temperature is reached, the power of the electric heating rod 202 is kept constant. The drying plate 201 heats the temperature inside the mounting frame 10 so that the temperature inside the mounting frame 10 reaches the drying temperature (for example, the drying temperature of a common nylon microporous filter membrane can generally be controlled at 80-100℃). After the drying component 2 has been working for a period of time, the temperature inside the mounting frame 10 reaches the drying temperature. When the microporous filter membrane passes through, it dries the microporous filter membrane. Through the setting of the drying component 2, the air temperature inside the mounting frame 10 is heated so that the air reaches the drying temperature. The hot air will not blow directly on the microporous filter membrane and will not cause physical damage to the surface of the microporous filter membrane, thus ensuring the integrity of the membrane's appearance.

[0030] The specific working method of the blocking component 3 is as follows: the second motor 302 starts and drives the bidirectional screw 306 to rotate. The rotation of the bidirectional screw 306 drives the moving blocks 304 to move closer to each other along the slide groove 305. The moving blocks 304 move closer to each other and drive the sealing plates 303 to move closer to each other. When the gap between the two sets of sealing plates 303 is adapted to the microporous filter membrane, the second motor 302 is turned off. The setting of the blocking component 3 makes it easy to seal the mounting frame 10, which greatly reduces the energy loss inside the mounting frame 10 (there is a gap between the microporous filter membrane and the two sets of sealing plates 303, and energy will still be lost. The heat insulation coating inside the sealing plates 303, the mounting frame 10, and the blocking component 3 greatly reduces the energy loss. When the electric heating rod 202 is working continuously, the temperature inside the mounting frame 10 can always dry the microporous filter membrane), thereby ensuring that the temperature inside the mounting frame 10 is always adapted to the drying temperature of the microporous filter membrane.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
