Description

Technical Field

[0001] The utility model relates to the technical field of ultrafiltration membranes, in particular to a disassembly and assembly structure of ultrafiltration membranes. Background Art

[0002] Ultrafiltration membrane is a microporous filtration membrane with consistent pore size specifications and a rated pore size range of less than 0.01 microns. By applying appropriate pressure on one side of the membrane, solute molecules smaller than the pore size can be screened out to separate particles with a molecular weight greater than 500 Daltons (atomic mass units) and a particle size greater than 10 nanometers. Ultrafiltration membrane is one of the earliest developed polymer separation membranes, and ultrafiltration devices were industrialized in the 1960s. In the prior art, the installation of the filter element of the ultrafiltration membrane is prone to friction and collision with the inner wall of the cylinder due to the operator's carelessness, which may cause damage. By setting up a protective mechanism, the possibility of damage to the filter element during installation is reduced. During the use of the ultrafiltration membrane, an ultrafiltration membrane disassembly and assembly structure is required for disassembly and assembly;

[0003] Announcement No. CN212017409U discloses a disassembly and assembly structure of an ultrafiltration membrane, including a damping spring, an arc plate, an insert, a slot, a rubber layer, a slide plate and a slide groove, wherein several groups of the damping springs are fixedly connected in the height direction along the inner wall of the cylinder, two groups of the arc plates are fixedly connected to the other end of the damping springs, and the two groups of the arc plates wrap the filter element together, the rubber layer is arranged on the surface of the arc plate, the slide plate is fixedly connected to the side wall of the filter element, the slide groove is arranged in the height direction along the rubber layer, the slide plate and the slide groove are slidably connected to each other, the insert block is fixedly connected to the bottom side of the inner wall of the cylinder, the slot is arranged in the bottom wall of the filter element, and the insert block and the slot are plugged into each other;

[0004] There may be two problems when using it. First, during the installation of the filter element, the worker needs to hold and control the clamping block on one side to expand the distance between the two clamping blocks, thereby facilitating the installation of the filter element. However, during the removal of the filter element, the clamping block fits tightly against the filter element, making it difficult for the worker to operate, increasing the complexity of the operation and reducing work efficiency. Second, after clamping the filter element, the worker needs to fix the filter element with multiple plug-in blocks to make it less likely for the filter element to loosen. This requires the worker to perform more operating steps, which is time-consuming and labor-intensive. Therefore, we propose a disassembly and assembly structure for an ultrafiltration membrane.
