Description

Technical Field

[0001] The utility model relates to the field of stacking, packaging and transportation of finished membrane element products, in particular to a semi-flexible flat plate filtration membrane element stacking and packaging integrated device. Background Art

[0002] During the transfer and handling of flat membrane elements, rigid flat membrane elements can maintain a flat and smooth membrane through their own supports, and the degree of damage is easily controlled. Semi-flexible flat membrane elements are different from traditional rigid flat membranes. Except for the very small amount of hard material at the two ends or the center, the rest of the membrane is flexible. When multiple semi-flexible flat membrane elements are laid flat and stacked, the membrane is easily damaged when folded, and the hard material of the flexible flat membrane elements is also easy to bend. At the same time, the membrane surface is also easy to stick to adjacent membrane elements when they come into contact in a humid environment. Therefore, semi-flexible flat membrane elements are more difficult to preserve during the stacking process. It can be seen that the stacking, handling and packaging processes of semi-flexible membrane elements have higher requirements, and a semi-flexible flat membrane element stacking device is urgently needed to solve the above problems. Utility Model Content

[0003] The utility model can solve the problems of stacking, packaging, moving, loading and unloading of semi-flexible flat plate filtering membrane elements.

[0004] This utility model patent is implemented as follows: a semi-flexible flat filter membrane element stacking device includes three parts: a frame, a membrane element stacking package and a movable base.

[0005] The frame is used to fix the membrane element stacking package in the device. It is located on the outside of the element stacking package and is used to fix and adjust the position of the membrane element in the device. The frame includes six parts: a limiting slide rod, a connecting rod, a hook rod, a hook clip, a slider and a small pallet. All configurations can be disassembled and assembled, and the usage function can be adjusted according to the application scenario.

[0006] Furthermore, there are four limit slide bars, which are installed in pairs relative to each other, with the upper and lower ends fixed. The lower ends of the limit slide bars are fixed to the movable base, and the upper ends of the limit slide bars are fixed by connecting rods; the fixing methods include welding fixation, through-hole insertion fixation or bracket fixation.

[0007] Furthermore, the limiting slide rod is provided with a limiting opening, which is opened at a certain height in the vertical direction. The slider placed therein will be constrained in the vertical direction of the limiting opening when moving, and the constraint height can be selected from 1.0 to 1.5 meters; in the horizontal direction, the slider is required to be limited to the maximum width range of the membrane element stacking device, and the width of the membrane element stacking device can be selected from 0.5 to 0.8 meters; precise size control can ensure that the membrane element stacking remains flat.

[0008] Furthermore, the hook clip is hung on the hook rod, the clip and the hook are integrated, the size of the clip can be adjusted according to the size of the protective film clamped, the clip width can be selected from 0.8-1.2 cm, and the height distance between the clip and the protective film can be selected from 15-25 mm.

[0009] The membrane element stacking package secures the double ends of the membrane elements, allowing for the equal placement of multiple membrane elements. This allows for the stacking and loading of a specific number of membrane elements as a whole. The size of the membrane element stacking package can be adjusted based on the size and quantity of the membrane elements. The package consists of four parts: the end plate, the membrane elements, the membrane element tail grooves, and the end plate.

[0010] Furthermore, the end long plate is an integral fixing part at one end after the membrane elements are stacked.

[0011] Furthermore, the tail groove of the membrane element is a temporary fixing piece of the other end of the membrane element after the membrane element is stacked, and can be used repeatedly.

[0012] Furthermore, the specific steps for making the membrane element stacking package are as follows:

[0013] (1) The slider is aligned with the limit opening of the limit slide rod and then inserted. Then the end tail long plate and the tail groove of the membrane element facing upward are inserted into the limit opening in the same way. The slider, the end tail long plate and the tail groove of the membrane element form a linked whole and can slide in the vertical direction within the limit opening of the limit slide rod;

[0014] (2) Adjust the membrane element slider upwards and insert a small card into the notch below the limit slide bar to control the end long plate and the membrane element tail groove to the required height;

[0015] (3) Apply double-sided tape to the bottom surface of the tail groove of the membrane element and bond it to the tail long plate through gluing;

[0016] (4) One end of the membrane element is placed vertically in the tail groove of the membrane element and arranged in an equal spacing. The flexible filling material clamped by the hook clip is placed in the gap between the two elements in turn;

[0017] (5) After all membrane elements are stacked, the end long plate fixes the other end of all membrane elements;

[0018] (6) Peel off the double-sided tape on the bottom surface of the tail groove of the membrane element. At this time, the tail groove of the membrane element is separated from the end long plate. Take the packing tape to tightly wrap the tail groove of the membrane element and the end long plate together to form a whole, that is, the formed membrane element stacking package.

[0019] After the membrane element stacking package is packed, the membrane element stacking package is packed in the box body in accordance with the space between the membrane element stacking package and the packaging box body, and the gap formed is filled with flexible filling material again to complete the box assembly, and the box body can be directly stacked and moved.

[0020] Furthermore, the flexible filling material adopts at least one of pearl cotton, foam, and wrapping film to ensure that the membrane surfaces of two adjacent membrane elements are not worn and protect the filter membrane.

[0021] The mobile base is located at the bottom of the frame and is used for moving the entire device and loading and unloading auxiliary components. It is used for moving and loading and unloading semi-flexible flat filter membrane elements.

[0022] According to the above description, a semi-flexible flat filter membrane element stacking device can achieve the following beneficial effects:

[0023] 1. The membrane elements go through fewer steps from production to packaging and molding, and the moving distance is short, which greatly reduces the risk of folding and damage of semi-flexible flat membrane elements;

[0024] 2. Different from traditional stacking structure devices, this device not only meets the requirements of stacking, moving, loading and unloading, but also meets the packaging requirements;

[0025] 3. The entire device has a simple structure, is easy to operate, occupies little space, and can be used in different working environments. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] For example, if 40 membrane elements are stacked at a time, the membrane elements are required to be stacked after molding to save space. Semi-flexible flat membrane elements consist of a diaphragm and a diaphragm fixing. They are characterized by being soft in the middle and hard at both ends. The diaphragm dimensions are 1100-1250mm long, 500mm wide, and 3mm thick. The diaphragm's water collection fixing is a 25mm-wide plastic sheet. Its internal structure features a water channel through which filtered water enters the water collection pipe. One end of the plastic sheet serves as the outlet, and the other as the tail. Once formed, the semi-flexible flat membrane element can be completely folded in half.

[0035] In this stacking configuration, the distance between the two limiting slide bars 1-1 corresponds to the long side of the membrane element. The short side of the membrane element (the water collection fixture) is perpendicular to the plane of the movable base 3, with the water outlet facing upward and the tail end facing downward. The tail end engages and secures with the tail groove of the membrane element, keeping the membrane slightly stretched.

[0036] The specific operations are as follows

[0037] (1) Preparation

[0038] The frame 1 has four columns, each inserted into the mobile base 3 and fixed vertically. Spacing requirements: ① Lengthwise: The center-to-center distance between the two limit slides 1-1 should be consistent with the membrane element dimensions, 1200mm (consistent with the length of the membrane element). ② Widthwise: The net distance between the two limit slides 1-1 should be 700mm. The frame 1 is secured at the top and bottom by connecting rods 1-2. Hook rods 1-3 are installed 300mm from the top of the frame 1.

[0039] The hook rods 1-3 are arranged at both ends of the frame 1, maintained at the same height, and are hung with hook clips 1-4, 41 in number, and the clip width is selected to be 1.0 cm.

[0040] The hook clips 1-4 clamp the ends of the flexible filling material (EPE) between the membrane elements along the longitudinal direction. The flexible filling material has an overall dimension of 1250 mm in length, 510 mm in width, and 0.5 mm in thickness. There are 41 pieces. The distance between the clips and the EPE is 25 mm.

[0041] The sliders 1-5 are four in number, with a length × width × thickness of 50mm × 50mm × 5mm. They slide into the required positions along the grooves of the limit slide rods 1-1 of the four columns respectively. The heights of the four sliders are consistent. Then the end long plates are inserted into the limit openings in the same way. The sliders 1-5 and the end long plates form a linked whole.

[0042] (2) Stacking operation

[0043] ①The first step is to fix the end long board 2-4.

[0044] Adjust the membrane element slider 1-5 upwards, and then insert the small card 1-6 into the lower notch a after the height is adjusted to limit the slider 1-5 from sliding downwards to control the height of the end long plate. Operate at both ends simultaneously.

[0045] ②The second step is to place the membrane element tail groove 2-3.

[0046] Select one end and slide the membrane element's tail groove 2-3, facing upward, along the grooves of the four pillars' limit slides 1-1, onto the top of the tail plate. See step b for details. Apply double-sided tape (20 mm x 50 mm) to both ends of the flat surface of the membrane element's tail groove 2-3. Place the tape against the tail plate 2-4, aligning their centers.

[0047] ③The third step is the membrane element stacking operation

[0048] Adjust the position of hook clips 1-4 on hook rods 1-3 and clamp the first piece of EPE (i.e., flexible filling material) on the outermost side. Place the first membrane element on top. Require the membrane to be in complete contact with the EPE. Continue to place the second piece of EPE, then the second membrane element. Repeat this sequence until all 40 membrane elements have been placed. Finally, place a piece of EPE on the outermost side.

[0049] ④The fourth step is to install the end long board 2-4

[0050] Select one end and place 2-4 end plates on one side of the membrane element outlet and secure it. Then wrap 10mm wide tape around the end plate five times to ensure that it does not fall off. Repeat the same procedure for the other end.

[0051] ⑤ Step 5: Protective measures in the middle and ends of membrane elements

[0052] A. Intermediate Protection

[0053] Take another piece of pearl cotton and wrap it around the middle end of the 40 membrane elements. Wrap them tightly with plastic tape and then remove hook clips 1-4.

[0054] B. Protection of both ends

[0055] Select one end and peel off the membrane element tail groove 2-3 and the end tail long plate 2-4. Remove the small card plate 1-6, slide the slider to the lower notch a, and remove the end tail long plate 2-4. Take another piece of pearl cotton and wrap it several times around the ends of the 40 membrane elements, then secure with plastic tape.

[0056] (3) Steps for loading into boxes

[0057] Before the membrane elements enter the stacking box c, a layer of foam board is pre-placed at the bottom of the stacking box c.

[0058] The membrane element stacking package 2 is inserted into the stacking box C. The membrane element stacking package 2 is slid into the stacking box C. After the membrane element stacking package 2 has been completely inserted into the stacking box C, the gaps on both sides and the top are also filled with flexible filling material. The stacking box C is now able to accommodate 40 membrane elements.

[0059] This patented utility model not only realizes on-site packaging of membranes, but also improves work efficiency. The membrane element transfer process is reduced, minimizing damage to the membrane.
