Description

Technical Field

[0001] This utility model relates to the field of membrane fixation technology, and in particular to a fixation device for a pervaporation membrane. Background Technology

[0002] Pervaporation membrane fixing equipment is mainly used to fix and support the pervaporation membrane, ensuring its stability and efficiency during separation and purification processes.

[0003] However, existing pervaporation membrane fixing equipment has several shortcomings: First, its fixing method is singular and cannot flexibly adapt to pervaporation membranes of different thicknesses or sizes. This is particularly disadvantageous in high-temperature operating environments, as the membrane material is prone to deformation and requires additional devices to press it down to prevent bending. Second, the equipment design fails to fully consider the problem of uniform stress on the pervaporation membrane, which may lead to local stress concentration on the membrane surface in actual applications, thereby causing rupture and affecting the reliability and service life of the equipment.

[0004] Therefore, this application provides a fixing device for a pervaporation membrane to overcome the deficiencies of the prior art. Utility Model Content

[0005] The purpose of this invention is to solve the problems of limited fixing methods and material deformation in existing vaporization membrane fixing equipment.

A drive motor is fixedly installed on the side wall of the fixing plate. A rotating rod is fixedly connected to the output end of the drive motor, and the rotating rod passes through the fixing plate. Two symmetrically arranged mounting slots are opened on the top of the fixing plate. Two symmetrically arranged moving blocks are connected to the outer side wall of the rotating rod. The moving blocks are located within the mounting slots, and a mounting plate is fixedly connected to the top of each moving block. A fixing mechanism is provided on the top of the mounting plate.

[0009] As a preferred technical solution, both the connecting block and the upright plate are provided with corresponding rotating openings, and the inner sidewalls of the two rotating openings are rotatably connected by the same pin.

[0010] As a preferred technical solution, the pressure head is arranged in a roller shape, and the surface of the pressure head is provided with anti-slip texture.

[0021] To make the technical means, technical features, utility model purpose and technical effects of this utility model easy to understand, the present utility model will be further described below with reference to specific illustrations. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0022] Example 1

[0023] Reference Figure 1-4 A fixing device for a pervaporation membrane includes a fixing plate 1, which is a planar plate structure used to support other components and provide an operating platform. Multiple support feet 2 are fixedly connected to the bottom of the fixing plate 1 to support the entire device and maintain its stability. A drive motor 3 is fixedly mounted on the side wall of the fixing plate 1, and a rotating rod 4 is fixedly connected to the output end of the drive motor 3, passing through the fixing plate 1. Two symmetrically arranged mounting slots 6 are formed at the top of the fixing plate 1 to accommodate moving blocks 5. Two symmetrically arranged moving blocks 5 are connected to the outer wall of the rotating rod 4, and the outer wall of the rotating rod 4 has two opposite external threads. Both moving blocks 5 have threaded openings. The inner sidewall of the nozzle is threadedly connected to the outer sidewall of the rotating rod 4. This design allows the two moving blocks 5 to move in opposite directions when the rotating rod 4 rotates. One moving block 5 moves in one direction, while the other moves in the opposite direction, thus creating an adjustable distance between the two moving blocks 5 to adapt to different operational needs. The moving blocks 5 are located in the mounting groove 6, and a mounting plate 7 is fixedly connected to the top of the moving blocks 5. The top of the mounting plate 7 is equipped with a fixing mechanism. The two moving blocks 5 are located in the mounting groove 6 and move within the mounting groove 6 as the rotating rod 4 rotates. The mounting plate 7 moves laterally under the drive of the moving blocks 5 to accommodate pervaporation membranes of different sizes.

[0024] The fixing mechanism includes two symmetrically arranged side plates 11 on the top of the mounting plate 7, forming a stable support frame. A common rotating rod 12 is fixedly connected to the opposite side of the two side plates 11. A rotating plate 13 is rotatably sleeved on the outer wall of the rotating rod 12. A pressure head 14 and a connecting block 16 are fixedly connected to both ends of the rotating plate 13, respectively. A cylinder 15 is hinged to the top of the mounting plate 7. A vertical plate 17 is fixedly connected to the top of the cylinder 15. The vertical plate 17 is connected to the connecting block 16. Corresponding rotating openings are provided on both the connecting block 16 and the vertical plate 17. The inner sides of the two rotating openings... The walls are rotatably connected by the same pin. The positions and dimensions of the two rotating ports are perfectly matched to ensure that the pin can be smoothly inserted and rotated. The pressure head 14 is set in a roller shape, and the surface of the pressure head 14 is provided with anti-slip texture. The roller-shaped structure of the pressure head 14 is conducive to processing anti-slip texture on its surface, enhancing the contact friction with the pervaporation membrane, thereby further ensuring the stability of the fixing effect. The anti-slip texture can be designed as a mesh, wave, or other texture structure that can increase friction to ensure effective contact and stability between the pressure head 14 and the membrane surface.

[0025] Two symmetrically arranged limiting rods 8 are fixedly connected to the outer wall of the mounting plate 7. The top of the fixing plate 1 has two sets of limiting grooves 9. The two limiting grooves 9 of the same set are located on both sides of the mounting groove 6. The limiting rods 8 are located in the limiting grooves 9. The bottom of the limiting rods 8 is provided with a semi-circular pad 10. The semi-circular pad 10 is made of wear-resistant material and has good corrosion resistance and high temperature resistance, ensuring long-term stable operation under harsh working conditions. The semi-circular pad 10 is rolled in connection with the bottom of the limiting groove 9. This design ensures that the limiting rods 8 can move smoothly in the limiting grooves 9 during use, reducing friction and improving the reliability and service life of the equipment.

[0026] Operating procedure: The pervaporation membrane is placed on top of the fixed plate 1, and then secured on the fixed plate 1 by a fixing mechanism. The drive motor 3 is started, and its output rotates, causing the rotating rod 4, which is fixedly connected to it, to rotate as well. The rotating rod 4 passes through the fixed plate 1, and its outer wall is connected to two symmetrically arranged moving blocks 5. As the rotating rod 4 rotates, the moving blocks 5 reciprocate within the mounting groove 6. This reciprocating motion allows the two moving blocks 5 to move laterally synchronously, thereby actuating the fixing mechanism on the mounting plate 7, achieving dynamic fixing and adjustment of the pervaporation membrane.

[0027] Then, the cylinder 15 is activated, which drives the rotating plate 13 to rotate, thereby causing the pressure head 14 to move up and down and press the pervaporation membrane. This allows for adjustment of the membrane's position and state, ensuring that it remains in optimal condition during operation and facilitating subsequent processing.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the content of the patent application of the present utility model shall fall within the technical scope of the present utility model.
