Description

Technical Field

[0001] This utility model relates to the field of fiberglass membrane shell installation technology, specifically a support and clamping structure for fiberglass membrane shells. Background Technology

[0002] Fiberglass membrane housings are the core pressure vessels in reverse osmosis (RO) water treatment systems, primarily used to house and protect RO membrane elements. The main structural material of the fiberglass membrane housing is glass fiber reinforced plastic, commonly known as fiberglass, a composite material composed of glass fibers (providing high strength) and thermosetting resins (usually epoxy resin, providing corrosion resistance and adhesion). It can house one to up to eight (or even more) standard-sized RO membrane elements (such as 4-inch or 8-inch diameter elements). Its operating principle is roughly as follows:

[0003] High-pressure raw water enters through the inlet, and the clean water (permeate) filtered through the membrane is collected at the product water outlet and discharged. The concentrated water that does not pass through the membrane is discharged through the concentrate outlet.

[0004] When installing and using fiberglass membrane housings, U-bolts, pipe supports, and brackets are typically used to clamp and fix the fiberglass membrane housing. However, the high-pressure pump, valve opening and closing, and water flow impact of the reverse osmosis system will generate significant vibrations. Over a long period of use, vibrations can cause the U-bolt connections to loosen, which in turn can lead to the risk of loosening at the clamping point of the fiberglass membrane housing. Therefore, in order to further improve the clamping stability of the fiberglass membrane housing, a support and clamping structure for the fiberglass membrane housing is provided.

Detailed Implementation

[0031] 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.

[0032] Please see Figures 1-4 In this embodiment of the present invention, a support and clamping structure for a fiberglass membrane shell includes a support frame 1 consisting of a support crossbar 101 and mounting holes 102. The mounting holes 102 are formed in pairs at the top of the support crossbar 101 and completely penetrate the bottom of the support crossbar 101. The support crossbar 101 provides installation support for the fiberglass membrane shell body 4. A limiting component 2 is installed at the top of the support crossbar 101 through the mounting holes 102. A clamping component 3 is provided above the fiberglass membrane shell body 4, penetrating the limiting component 2 to the bottom of the support crossbar 101. The clamping component 3 cooperates with the limiting component 2 to clamp and fix the fiberglass membrane shell body 4.

[0033] The limiting component 2 includes a positioning unit and an anti-loosening unit. The positioning unit provides positioning for the placement of the fiberglass membrane shell body 4, and the anti-loosening unit provides initial pre-fixation for the positioning unit and provides anti-loosening limiting operation for the clamping component 3 after installation.

[0034] The positioning unit includes a positioning seat 201 and a through hole 202; the clamping assembly 3 includes an upper pressure steel strip 301, a screw 302, and a locking nut 303.

[0035] The top center of the positioning seat 201 is formed with an arc-shaped groove that matches the outer diameter of the outer wall at both ends of the fiberglass membrane shell body 4. The fiberglass membrane shell body 4 is placed inside the arc-shaped groove of the positioning seat 201 to achieve positioning.

[0036] The through hole 202 is symmetrically opened on the top of the positioning seat 201 with the arc-shaped groove as the center and completely penetrates the bottom of the positioning seat 201;

[0037] The screws 302 are symmetrically fixed to the bottom end of the upper pressure steel strip 301. The upper pressure steel strip 301 is sleeved and fits against the outer side of the upper surface of the fiberglass membrane shell body 4. The two screws 302 pass through the two through holes 202 respectively and protrude to the bottom of the support crossbar 101. The locking nut 303 is threadedly connected to the screws 302 and pressed against the lower surface of the support crossbar 101 to achieve clamping and fixing of the fiberglass membrane shell body 4.

[0038] The positioning unit includes an arc-shaped docking plate 203 and a side V-shaped folding plate 204;

[0039] Multiple arc-shaped docking plates 203 are arranged in a ring around the through hole 202 and fixed to the bottom of the positioning seat 201;

[0040] Multiple side V-shaped folding plates 204 are provided, and the multiple side V-shaped folding plates 204 and the arc-shaped connecting plate 203 are staggered along the circumferential direction, and the lower bending part of the side V-shaped folding plate 204 bends outward.

[0041] When the positioning seat 201 is placed on the top of the support crossbar 101, it passes through the mounting hole 102 through the arc-shaped connecting plate 203 and the side V-shaped folding plate 204. The lower bent part of the side V-shaped folding plate 204 protrudes to the bottom of the support crossbar 101 to achieve the pre-fixation of the positioning seat 201.

[0042] The positioning unit also includes a V-shaped hook plate 205;

[0043] V-shaped hook plate 205 is fixed to the bottom end of the bent part below the side V-shaped folding plate 204. The screw 302 passes through multiple arc-shaped connecting plates 203, the middle part of the side V-shaped folding plate 204, and the middle part of multiple V-shaped hook plates 205 in sequence. When the locking nut 303 is screwed into the screw 302, the locking nut 303 is located in the middle area of ​​multiple V-shaped hook plates 205. The top of the hook part at the bottom end of the V-shaped hook plate 205 is in contact with the lower surface of the locking nut 303, which is used to limit the downward movement of the V-shaped hook plate 205.

[0044] In this embodiment, it should be noted that the support frame 1 is horizontally fixed in the external rectangular frame to provide support for the installation of the fiberglass membrane shell body 4.

[0045] The installation steps for the fiberglass membrane shell body 4 are as follows:

[0046] First, install the two sets of limiting components 2 on the two support crossbars 101 respectively. Then, align the V-shaped hook plate 205 with the mounting hole 102 and insert it. During this process, the V-shaped hook plate 205 and the side V-shaped folding plate 204 will be squeezed by the inner wall of the mounting hole 102 and deform and shrink inward, so that the V-shaped hook plate 205 and the side V-shaped folding plate 204 can pass smoothly through the mounting hole 102.

[0047] Finally, the lower bends of the V-shaped hook plate 205 and the side V-shaped folding plate 204 protrude to the bottom of the support crossbar 101, and the lower bends of the V-shaped hook plate 205 and the side V-shaped folding plate 204 return to their initial state under the elastic force of their own materials. The lower bend of the side V-shaped folding plate 204 forms a limit with the bottom of the support crossbar 101, thus achieving the pre-fixation of the positioning seat 201.

[0048] Then, the fiberglass membrane shell body 4 can be placed inside the arc-shaped grooves of the two positioning seats 201. After determining the position of the fiberglass membrane shell body 4, the clamping assembly 3 can be taken out. The upper pressure steel strip 301 is attached to the top of the fiberglass membrane shell body 4, and the two screws 302 are respectively passed through the two through holes 202, and then passed through the middle area of ​​multiple arc-shaped butt plates 203, the middle area of ​​the side V-shaped folding plate 204, and the middle area of ​​multiple V-shaped hook plates 205 in sequence. Then, the locking nut 303 is threadedly connected to the screw 302 and tightened.

[0049] During the tightening process, the locking nut 303 moves upward. When the locking nut 303 contacts the hooks of the multiple V-shaped hook plates 205, it compresses them, causing the hooks to bend outward. This allows the locking nut 303 to smoothly pass through the area of ​​the hooks of the multiple V-shaped hook plates 205 and enter the middle area between the lower bend of the multiple V-shaped hook plates 205 and the side V-shaped folding plate 204. Then, the locking nut 303 continues to be tightened (it should be noted that the tightening of the locking nut 303 is operated through a polygonal sleeve. During the tightening process, the polygonal sleeve keeps compressing the hooks of the V-shaped hook plates 205, and the hooks of the V-shaped hook plates 205 do not affect the tightening of the locking nut 303). At this time, the upward movement of the locking nut 303 compresses the lower bend of the side V-shaped folding plate 204, causing the lower bend of the side V-shaped folding plate 204 to bend upward and finally fit against the lower surface of the support crossbar 101 (e.g., Figure 2 At this point, the installation of clamping component 3 is completed, and clamping component 3 clamps the fiberglass membrane shell body 4. At the same time, limiting component 2 and support crossbar 101 are further fixed.

[0050] Afterwards, the polygonal sleeve that was used to tighten the locking nut 303 is removed, and the hook of the V-shaped hook plate 205 loses external pressure and resets. Finally, the top of the hook of the V-shaped hook plate 205 approaches and fits the lower surface of the locking nut 303, thereby limiting the downward movement of the locking nut 303 and achieving the anti-loosening effect, further improving the installation stability of the fiberglass membrane shell body 4.

[0051] Please refer to this carefully. Figures 1-4 The outer diameter of the multiple arc-shaped mating plates 203 matches the inner diameter of the mounting hole 102, the inner diameter of the multiple arc-shaped mating plates 203 matches the outer diameter of the screw 302, and the height of the arc-shaped mating plates 203 matches the height of the support crossbar 101.

[0052] The lower bend of the side V-shaped folding plate 204 and the V-shaped hook plate 205 form a ">" shape, and the distribution diameter at the connection between the lower bend of the side V-shaped folding plate 204 and the V-shaped hook plate 205 is larger than the inner diameter of the mounting hole 102.

[0053] The hook tips of multiple V-shaped hook plates 205 have a diameter greater than the outer diameter of the screw 302 and smaller than the inscribed circle diameter of the polygonal outer wall of the locking nut 303.

[0054] In this embodiment: the outer diameter of multiple arc-shaped mating plates 203 matches the inner diameter of the mounting hole 102 to achieve positioning and installation of the positioning seat 201 and prevent it from shaking;

[0055] The ">" shaped structure between the lower bending part of the side V-shaped folding plate 204 and the V-shaped hook plate 205 can provide a pre-fixing force for the initial installation of the positioning seat 201, which facilitates the positioning and placement of the fiberglass membrane shell body 4.

[0056] The hook tips of multiple V-shaped hook plates 205 are distributed with a diameter greater than the outer diameter of the screw 302, so that the V-shaped hook plates 205 do not affect the installation of the screw 302.

[0057] By using a structure in which the hook tips of multiple V-shaped hook plates 205 have a diameter smaller than the inscribed circle diameter of the polygonal outer wall of the locking nut 303, the hooks of the multiple V-shaped hook plates 205 can block the downward movement of the locking nut 303, thus preventing the locking nut 303 from loosening and moving downward.

[0058] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
