Abstract
Description
Technical Field
[0001] This utility model relates to the field of ceramic membrane module technology, specifically a porous tubular silicon carbide ceramic membrane shell. Background Technology
[0002] Ceramic membrane modules are industrial filtration equipment composed of inorganic ceramic membrane elements centrally packed into pressure-resistant shells of varying sizes. Their optimized structure increases the packing density by 65% compared to traditional structures. Made from inorganic materials such as alumina and zirconium oxide through sintering, they possess characteristics such as high-temperature resistance and acid / alkali corrosion resistance, providing filtration precision ranging from microfiltration to nanofiltration. The modules feature a design combining a central flow channel and a honeycomb-shaped hexagonal flow channel, while the sealing system employs a triple-reinforced protrusion structure and an elastic pressure feedback mechanism.
[0003] In existing technologies, multiple sets of bolts are typically used to fix the end caps of ceramic membrane housings. Due to the large diameter of the end caps and the need to ensure uniform sealing, as many as 6 to 12 or even more bolts are usually arranged around the circumference for fastening. This makes the installation and disassembly process extremely cumbersome and time-consuming. In situations where frequent cleaning, inspection, or replacement of the membrane core is required, the above cumbersome operations must be repeated for each maintenance, which greatly reduces the operating efficiency and maintenance response speed of the equipment, seriously affects the continuity of production and the convenience of operation and maintenance, and makes it difficult to meet the needs of modern industry for efficient and rapid disassembly and assembly. Therefore, the existing porous tubular silicon carbide ceramic membrane housings need to be improved. Utility Model Content
[0004] The purpose of this invention is to provide a porous tubular silicon carbide ceramic membrane shell to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a porous tubular silicon carbide ceramic membrane shell, comprising a shell, a drain pipe and a slag discharge pipe being installed through the outer wall of the shell, sealing rings being provided at both ends of the shell, and placement grooves being provided at both ends of the shell, a limiting component being provided on the inner wall of the placement groove, the limiting component comprising a mounting plate, an adjusting pipe being fixedly connected to the top of the mounting plate, a return spring being fixedly connected to the inner wall of the adjusting pipe, and a ball head being fixedly connected to the other end of the return spring, an end cap being installed on the inner wall of the shell, and a connecting block being fixedly connected to the outer wall of the end cap, connecting pipes being installed at both ends of the shell, and sealing components being provided on the outer walls of the shell and the connecting pipes.
[0006] Preferably, a connecting block is slidably connected to the outer wall of the ball head, and the ball head forms a compression motion with the return spring through the connecting block.
[0007] Preferably, the outer wall of the connecting block is provided with a mounting hole, and the mounting hole and the ball head are on the same vertical line. The ball head and the mounting hole are engaged by a return spring.
[0008] Preferably, the sealing ring is disposed between the housing and the end cap, and the sealing ring forms a compression seal with the housing through the end cap.
[0009] Preferably, the sealing assembly includes an adjusting frame, and a push ring is installed on the inner wall of the adjusting frame, and a first compression sealing ring is installed at the other end of the push ring.
[0010] Preferably, an adjusting ring is installed at the other end of the first extrusion sealing ring, and both ends of the first extrusion sealing ring are slidably connected to a push ring and an adjusting ring, wherein the push ring rotates through the first extrusion sealing ring and the adjusting ring.
[0011] Preferably, a second compression sealing ring is slidably connected to the other end of the adjusting frame, and an adjusting ring is slidably connected to the other end of the second compression sealing ring. The adjusting frame rotates through the second compression sealing ring and the adjusting ring.
[0012] Compared with the prior art, the beneficial effects of this utility model are: it is used for porous tubular silicon carbide ceramic membrane shells; 1. By aligning and pressing down the end cap with the connecting block and limiting component, the connecting block fixed on its outer wall is inserted into the placement groove and squeezes the ball head in the limiting component. Under pressure, the ball head retracts the adjusting tube and compresses the return spring. When the connecting block is pressed down to the end, the ball head pops out again under the elastic force of the return spring and is locked in the mounting hole of the connecting block, thereby realizing the quick locking of the end cap. This enables the quick and convenient installation and removal of the end cap without the need for bolt fastening, improving assembly efficiency. Furthermore, the elastic limiting and sealing cooperation ensures the reliability of the connection and the sealing performance, making it suitable for ceramic membrane systems that require frequent disassembly and maintenance. 2. By setting up a sealing component, the diameters of the two extrusion sealing rings are changed synchronously to ensure a tight fit between the connecting pipe and the outer wall of the housing. This achieves self-adaptive installation and reliable sealing of the sealing component. The structure realizes the linkage adjustment of the two sealing rings through a single drive, adapting to different specifications of housings and connecting pipes. This improves the versatility and convenience of ceramic diaphragm housing installation, effectively enhances sealing reliability, prevents leakage during operation, and facilitates disassembly and maintenance.

[0015] 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.
[0016] Please see Figures 1-4 This utility model provides a technical solution: a porous tubular silicon carbide ceramic membrane shell, including a shell 1. A drain pipe 10 and a slag discharge pipe 11 are installed through the outer wall of the shell 1. Sealing rings 2 are provided at both ends of the shell 1. The sealing rings 2 are located between the shell 1 and the end cap 5, and the sealing rings 2 and the shell 1 form a compression seal through the end cap 5. The sealing is completed synchronously by the locking action of the end cap 5 through the sealing rings 2, without the need for additional sealing steps, ensuring that the fluid inside the membrane shell will not leak from the connection of the end cap 5. Both ends of the shell 1 are provided with placement grooves 3. The inner wall of the placement grooves 3 is provided with a limiting component 4. The limiting component 4 includes a mounting plate 401, and an adjusting pipe 402 is fixedly connected to the top of the mounting plate 401. A return spring 403 is fixedly connected to the inner wall of the adjusting pipe 402. The other end is fixedly connected to a ball head 404, and a connecting block 6 is slidably connected to the outer wall of the ball head 404. The ball head 404 and the return spring 403 form a compression motion through the connecting block 6. The return spring 403 provides power for subsequent automatic pop-out and locking, ensuring the stability and repeatability of the quick locking mechanism. An end cover 5 is installed on the inner wall of the housing 1, and a connecting block 6 is fixedly connected to the outer wall of the end cover 5. An installation hole 7 is opened on the outer wall of the connecting block 6, and the installation hole 7 is on the same vertical line as the ball head 404. The ball head 404 and the installation hole 7 form a locking motion through the return spring 403. The ball head 404 converts the elastic force of the return spring 403 into an effective locking force, ensuring that the end cover will not accidentally loosen under operating pressure, which significantly improves the mechanical strength and safety of the connection. Furthermore, connecting pipes 8 are installed at both ends of the housing 1, and sealing components 9 are provided on the outer walls of the housing 1 and the connecting pipes 8. The sealing components 9 include an adjusting frame 901, and a push ring 902 is installed on the inner wall of the adjusting frame 901. A first compression sealing ring 903 is installed at the other end of the push ring 902. Through the push ring 902, the external pushing of the adjusting frame 901 can be effectively converted into a radial adjustment force on the first compression sealing ring 903, providing a reliable mechanical drive path for achieving a tight seal on the outer wall of the connecting pipe 8. An adjusting ring 904 is installed at the other end of the first compression sealing ring 903, and the push ring 902 and the adjusting ring 904 are slidably connected at both ends of the first compression sealing ring 903. The push ring 902 passes through the first compression sealing ring 903. The adjusting frame 901 rotates with the adjusting ring 904, providing a structural basis for precise and uniform adjustment of the sealing ring diameter and helping to form a consistent circumferential sealing pressure. The other end of the adjusting frame 901 is slidably connected to the second extrusion sealing ring 905, and the other end of the second extrusion sealing ring 905 is slidably connected to the adjusting ring 904. The adjusting frame 901 rotates with the second extrusion sealing ring 905 and the adjusting ring 904. The adjusting frame 901 can simultaneously drive the first extrusion sealing ring 903 and the second extrusion sealing ring 905 to perform coordinated radial adjustment, thereby achieving synchronous and adaptive sealing of the connecting pipe 8 and the housing 1, which greatly improves the integration, ease of operation and sealing reliability of the sealing assembly.
[0017] Example 1: During installation, align the end cap 5 with the mounting port on the housing 1 and apply axial pressure downwards. The connecting block 6 fixed to the outer wall of the end cap 5 is then inserted into the placement groove 3 inside the housing. During the downward movement, it squeezes the ball head 404 in the limiting assembly 4. After being forced, the ball head 404 retracts into the adjusting tube 402, while compressing the return spring 403 at its rear end. When the connecting block 6 is pressed down to the predetermined position, the mounting hole 7 on it is just aligned with the ball head 404. At this time, the return spring 403 releases its elastic force, pushing the ball head 404 outwards and locking it into the mounting hole 7, thus achieving quick and reliable locking of the end cap. Disassembly is the same; simply pull the end cap 5 with force. Example 2: When the housing 1 and the connecting pipe 8 need to be installed, by pushing the adjusting frame 901 in the sealing assembly 9, the push ring 902 is driven to move, pulling the first compression sealing ring 903 to generate radial contraction deformation along the adjusting ring 904, so as to tightly fit the outer wall of the connecting pipe 8. At the same time, the adjusting frame 901 drives the second compression sealing ring 905 to rotate with the adjusting ring 904 and undergo radial adjustment, thereby synchronously changing the diameter of the two compression sealing rings, so that they tightly fit the connecting pipe 8 and the outer wall of the housing 1, realizing the self-adaptive installation and reliable sealing of the sealing assembly 9.
