Description

Technical Field

[0001] The utility model relates to the technical field of membrane separation, in particular to an end plate fixing structure for preventing instability of a separation membrane shell. Background Art

[0002] The end plates of the current membrane housing are mainly fixed by three arc-shaped blocks, which are in turn fixed by a circular safety ring. There are two traditional types of blocks. One is that the force-bearing surfaces are two planes that are completely perpendicular to the axis of the membrane housing; the other is that the surface in contact with the membrane housing is a plane and the surface in contact with the end plate is an inclined surface. When these two types of blocks are working, the water pressure inside the membrane housing will eventually act on the blocks, and the forces acting on the blocks are all shear forces. Therefore, the blocks need to be designed to be very thick to withstand the shear forces. At the same time, these two types of blocks are prone to deflection and instability due to structural reasons after long-term use. After instability, the original surface force becomes a linear force, which can easily get the blocks stuck in the block grooves, causing great inconvenience in the maintenance and disassembly of the separation membrane housing. Utility Model Content

[0003] In order to solve the problem mentioned above that the existing block structure may deflect and become unstable after long-term use, which makes the maintenance and disassembly of the separation membrane housing difficult, the utility model proposes an end plate fixing structure for preventing the separation membrane housing from destabilizing. The utility model designs the end plate and the sealing plate into a bowl-shaped structure, which improves the force effect of the end plate fixing structure. The edge of the end plate rests on the inclined surface of the insertion end of the block to decompose the axial thrust, solving the problem that the block is prone to deflect and become unstable when subjected to force and then gets stuck in the block groove, while reducing the difficulty of disassembling the separation membrane housing product.

[0004] The utility model proposes an end plate fixing structure for preventing instability of a separation membrane shell, which specifically comprises a stopper, a separation membrane shell, a sealing plate and an end plate, wherein the interior of the separation membrane shell is provided with a sealing plate, an end plate and a stopper in sequence from the inside to the outside, a stopper groove is provided on the inner surface of the separation membrane shell, and a stopper is provided in the stopper groove; the end plate is a bowl-shaped structure, and the edge rests on the stopper; the sealing plate is a bowl-shaped structure and fits the end plate; the stopper is an annular stopper, and the stopper comprises an insertion end, which is inserted into the stopper groove; the force-bearing surfaces on both sides of the insertion end are parallel to each other and are inclined surfaces.

[0005] Furthermore, the end plate is provided with screws, and the stopper is fixed by the screws.

[0006] Furthermore, a clean water channel is provided at the center of the sealing plate, and the clean water channel passes through the center of the end plate.

[0007] Furthermore, the cross-sectional shape of the stopper is a herringbone shape.

[0008] Furthermore, the end plate fixing structure for preventing the separation membrane housing from destabilizing further comprises a label, which is sleeved on the outside of the clean water channel to fix the end plate on the sealing plate.

[0009] The beneficial effects of the end plate fixing structure for preventing instability of the separation membrane housing described in the utility model are:

[0010] (1) The end plate fixing structure for preventing instability of the separation membrane housing described in the utility model, by setting the sealing plate and the end plate into a bowl-shaped structure, the axial thrust received by the end plate fixing structure can be effectively transmitted to the stopper, and then act on the separation membrane housing through the stopper, thereby optimizing the force structure and saving the use of raw materials;

[0011] (2) The utility model discloses an end plate fixing structure for preventing instability of a separation membrane housing, which decomposes the axial thrust into two components by setting the force-bearing surface of the stop block to an inclined surface. One component is the positive pressure of the end plate on the inclined surface of the insertion end of the stop block, which ultimately acts on the area where the inclined surfaces of the separation membrane housing and the stop block fit together. The other component is the shear force of the end plate on the stop block, which ultimately acts on the separation membrane housing. This enhances the stability of the end plate fixing structure, reduces the shear force that the stop block needs to withstand, and thus reduces the weight of the stop block, thereby saving the use of raw materials.

The end plate fixing structure for preventing the destabilization of the separation membrane housing described in the embodiment specifically includes a stopper 1, a separation membrane housing 2, a sealing plate 3 and an end plate 4. The interior of the separation membrane housing 2 is provided with a sealing plate 3, an end plate 4 and a stopper 1 in sequence from the inside to the outside. A stopper groove is provided on the inner surface of the separation membrane housing 2, and a stopper 1 is provided in the stopper groove; the end plate 4 is a bowl-shaped structure, and the edge rests on the stopper 1; the sealing plate 3 is a bowl-shaped structure and fits the end plate 4, and the sealing plate 3 and the end plate 4 fit completely; the stopper 1 is an annular stopper with a cross section of a human body. The block 1 has a U-shaped structure, and includes an insertion end 7, which is inserted into the block groove; the force-bearing surfaces on both sides of the insertion end 7, namely surface 1 8 and surface 2 9, are parallel to each other; surface 1 8 and surface 2 9 are inclined surfaces, which form a certain angle with the axis of the separation membrane housing 2; the block groove is pre-embedded, and the groove wall on one side of the block groove close to the port position of the separation membrane housing 2 is an inclined surface and cooperates with surface 1 8, and surface 2 9 contacts and cooperates with the inclined surface of the outer ring edge of the end plate 4, and the axial thrust is transmitted to the block 1 through the sealing plate 3 and the end plate 4 of the bowl-shaped structure.

[0022] The stopper 1 also includes a support end 11, which rests on the inner wall of the separation membrane housing 2. The support end 11 and the insertion end 7 together form a herringbone structure of the stopper 1. The support end 11 supports the stopper 1 to prevent the stopper 1 from tilting in the stopper groove.

[0023] The end plate 4 is provided with a threaded hole, and the threaded hole is provided with a screw 5, and the stopper 1 is fixed by the screw 5, and the stopper 1 is restricted in the stopper groove. The screw 5 is a hexagon socket screw.

[0024] A clean water channel 10 is provided at the center of the sealing plate 3 , and the clean water channel 10 passes through the center of the end plate 4 and the sign 6 .

[0025] The end plate fixing structure for preventing instability of the separation membrane housing also includes a nameplate 6, a threaded hole is arranged at the center of the nameplate 6; a thread is arranged on the outer surface of the clean water channel 10 of the sealing plate 3 facing the port of the separation membrane housing 2, and the nameplate 6 is arranged on the clean water channel 10 by means of a threaded connection, so that the end plate 4 is fixed to the sealing plate 3; a protruding structure is arranged on the side of the nameplate 6 facing the end plate 4, and the protruding structure is in contact with the center of the end plate 4 to ensure the stability of the structure of the end plate 4.

[0026] The specific working principle of the end plate fixing structure for preventing instability of the separation membrane housing described in the utility model is explained as follows:

[0027] When the product is used, the internal water pressure first acts on the sealing plate 3 and then is transmitted to the surface 29 of the stopper 1 through the end plate 4, and finally acts on the separation membrane housing 2 through the surface 18 of the stopper 1. The surface 18 and the surface 29 of the stopper 1 are designed to have a certain angle with the axis of the separation membrane housing 2. Under the stress state, the axial thrust of the internal water pressure on the end plate 4 is formed into two components through the action of the stopper 1. One component is the positive pressure of the end plate 4 on the surface 29 of the stopper 1, which finally acts on the area where the separation membrane housing 2 and the surface 18 of the stopper 1 match, and the other component is the shear force of the end plate 4 on the stopper 1, which finally acts on the separation membrane housing 2.
