Description

Technical Field

[0001] This utility model relates to the field of casting device technology, and in particular to a curtain membrane module casting device. Background Technology

[0002] As is well known, curtain membrane modules are the core separation unit in water treatment fields (such as advanced municipal wastewater treatment, industrial wastewater reuse, and drinking water purification). Their performance depends on the sealing performance of the membrane fibers and the end caps, the uniformity of the membrane fiber distribution, and the long-term operational stability. Among these factors, the casting process is a key factor in determining the quality of curtain membrane modules—multiple PVDF or PES membrane fibers are fixed to the module shell using potting compound to form an end cap structure that combines sealing, support, and water collection functions. This ensures precise alignment between the membrane fiber ends and the water collection channel, preventing cross-contamination between raw water and permeate.

[0003] However, traditional curtain-type membrane module casting devices typically fix the membrane fiber bundles in the casting box and manually inject polyurethane or epoxy resin potting compound directly with a hand-held syringe. However, because the density of the adhesive is greater than that of the filling liquid, it is easy to accumulate and stagnate at the bottom of the casting cavity or in areas where the membrane fibers are dense.

[0004] Therefore, those skilled in the art have provided a curtain-type membrane module casting device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a curtain-type membrane module casting device. When in use, the servo motor drives the rotating disk to move the positioning protrusion along the slide rail and cooperate with the slider to slide within the limiting block, so that the casting box in the placement box can reciprocate. This can effectively reduce the phenomenon of local stagnation of adhesive and promote the full filling of the gaps between the membrane fibers with adhesive, thus avoiding sealing dead corners.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A curtain-type membrane module casting device includes a support frame, an mounting shell fixedly connected to the upper end of the support frame, a placement box disposed inside the mounting shell, a mounting bracket disposed on the upper end of the outer wall of an adjacent side of the support frame, storage slots being formed on both sides of the inner wall of the mounting bracket, a synchronous motor fixedly connected to the rear end of the inner wall of each storage slot, a screw fixedly connected to the output end of each synchronous motor, a clamping plate being threadedly connected to the outer wall of the screw, a protective shell fixedly connected to the outer wall of the rear end of the support frame, a servo motor fixedly connected to the inner wall of the protective shell, the output end of the servo motor penetrating the mounting shell and fixedly connected to a rotating disk, a positioning protrusion fixedly connected to the outer wall of the front end of the rotating disk, and a slide fixedly connected to one side of the outer wall of the front end of the placement box.

[0007] Compared with existing curtain membrane module casting devices, the above technical solution uses a servo motor to drive a rotating disk to move a positioning protrusion along the slide rail and a slider to slide within a limit block. This causes the casting box inside the box to reciprocate, which can effectively reduce local stagnation of adhesive and promote the full filling of the membrane fiber gaps with adhesive, thus avoiding dead corners in sealing.

[0008] Furthermore, the upper and lower parts of the front end of the inner wall of the mounting shell are fixedly connected to limit blocks, and the upper and lower parts of the outer wall of the front end of the placement box are fixedly connected to sliders, and the sliders are respectively slidably connected to the inner wall of the limit blocks. The above technical solution forms a precise guiding and limiting structure with the limiting block and the slider on the outer wall of the placement box, enabling the placement box to reciprocate laterally.

[0009] Furthermore, a PLC control panel is provided on one side of the outer wall of the front end of the mounting housing, and the PLC control panel is electrically connected to the servo motor and the synchronous motor respectively. With the above technical solution, the PLC control panel is electrically connected to both the servo motor and the synchronous motor, which facilitates the control of their switching.

[0010] Furthermore, spring telescopic rods are fixedly connected to the upper ends of the outer walls of adjacent sides of the bracket, and the telescopic ends of the spring telescopic rods are fixedly connected to the two sides of the outer wall of the mounting frame, respectively. The above technical solution allows the spring telescopic rod to facilitate the reciprocating motion of the box.

[0011] Furthermore, all the clamping plates are slidably connected to the inner wall of the storage slot; With the above technical solution, the clamping plates are all slidably connected to the inner wall of the storage tank, which facilitates the fixation of the upper end of the membrane filament.

[0012] Furthermore, the outer wall of the carriage is provided with a sliding groove, and the positioning protrusion is slidably connected to the inner wall of the sliding groove; The above technical solution facilitates the movement of the placement box by using a positioning protrusion that slides along the inner wall of the groove.

[0013] This utility model has the following beneficial effects: The present invention proposes a curtain-type membrane module casting device. Compared with the existing curtain-type membrane module casting devices, when this curtain-type membrane module casting device is in use, the servo motor drives the rotating disk to drive the positioning protrusion to slide along the slide rail and cooperate with the slider to slide within the limit block, so that the casting box in the placement box reciprocates. This can effectively reduce the phenomenon of local retention of adhesive and promote the adhesive to fully fill the gaps between the membrane fibers, avoiding sealing dead corners.

Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Reference Figure 1-7An embodiment of this utility model provides a curtain-type membrane component casting device, including a support 1, an mounting shell 11 fixedly connected to the upper end of the support 1, a placement box 12 disposed inside the mounting shell 11, a mounting bracket 2 disposed at the upper end of the outer wall of the adjacent side of the support 1, storage slots 22 are provided on both sides of the inner wall of the mounting bracket 2, a synchronous motor 23 is fixedly connected to the rear end of the inner wall of the storage slot 22, a screw 24 is fixedly connected to the output end of the synchronous motor 23, a clamping plate 25 is threadedly connected to the outer wall of the screw 24, a protective shell 3 is fixedly connected to the outer wall of the rear end of the support 1, a servo motor 31 is fixedly connected to the inner wall of the protective shell 3, the output end of the servo motor 31 passes through the mounting shell 11 and is fixedly connected to a rotating disk 32, a positioning protrusion 33 is fixedly connected to the outer wall of the front end of the rotating disk 32, and a slide 34 is fixedly connected to one side of the outer wall of the front end of the placement box 12.

[0017] Compared with existing curtain membrane module casting devices, this curtain membrane module casting device, when in use, uses a servo motor 31 to drive a rotating disk 32 to drive a positioning protrusion 33 to slide along a slide rail 35 of a slide frame 34, which in turn allows a slider 15 to slide within a limiting block 14, causing the casting box in the placement box 12 to reciprocate. This effectively reduces local stagnation of adhesive and promotes the full filling of the membrane fiber gaps with adhesive, avoiding dead corners in sealing.

[0018] Limiting blocks 14 are fixedly connected to the upper and lower parts of the front end of the inner wall of the mounting shell 11, and sliders 15 are fixedly connected to the upper and lower parts of the outer wall of the front end of the placement box 12. The sliders 15 are respectively slidably connected to the inner wall of the limiting blocks 14. The limiting block 14 and the slider 15 on the outer wall of the placement box 12 form a precise guiding and limiting structure, enabling the placement box 12 to reciprocate laterally.

[0019] A PLC control panel 13 is provided on one side of the front outer wall of the mounting housing 11. The PLC control panel 13 is electrically connected to the servo motor 31 and the synchronous motor 23 respectively. The PLC control panel 13 is electrically connected to the servo motor 31 and the synchronous motor 23 respectively, which facilitates the control of their switching.

[0020] A spring telescopic rod 21 is fixedly connected to the upper end of the outer wall of the adjacent side of the bracket 1. The telescopic ends of the spring telescopic rod 21 on the adjacent side are fixedly connected to both sides of the outer wall of the mounting bracket 2. The spring telescopic rod 21 facilitates the reciprocating motion of its placement box 12.

[0021] All clamping plates 25 are slidably connected to the inner wall of the storage slot 22; The clamping plates 25 are slidably connected to the inner wall of the storage groove 22, which facilitates the fixation of the upper end of the membrane filament.

[0022] The outer wall of the carriage 34 is provided with a groove 35, and the positioning protrusion 33 is slidably connected to the inner wall of the groove 35. The positioning protrusion 33 slides on the inner wall of the groove 35 to facilitate the movement of the placement box 12.

[0023] Working principle: During use, a syringe filled with polyurethane or epoxy resin potting compound is manually used to inject the compound into the casting box. At this time, the PLC control panel 13 starts the synchronous motor 23 on the side of the mounting bracket 2. The output end of the synchronous motor 23 drives the screw 24 in the storage slot 22 to rotate. Because the clamping plate 25 is threadedly connected to the screw 24 and is confined to the inner wall of the storage slot 22, the rotation of the screw 24 will drive the clamping plate 25 to slide in the storage slot 22, accurately clamping and fixing the upper end of the membrane filament to be cast. At the same time, the casting box corresponding to the lower end of the membrane filament is smoothly placed into the placement box 12 inside the mounting shell 11, ensuring that the casting box is in close contact with the inner wall of the placement box 12. The servo motor 31 in the rear protective shell 3 of the bracket 1 is started through the PLC control panel 13. The output end drives the rotating disk 32 to rotate. The positioning protrusion 33 at the front end of the rotating disk 32 rotates with it and slides in the groove 35 of the slide 34 at the front end of the placement box 12. With the guidance of the positioning protrusion 33 by the groove 35, the rotational motion is converted into the lateral driving force of the placement box 12. Since the placement box 12 is slidably connected to the limiting block 14 on the inner wall of the mounting shell 11 through the slider 15, the limiting block 14 further constrains the movement trajectory of the placement box 12, making it move smoothly back and forth in the horizontal direction. During this period, the spring telescopic rod 21 on the bracket 1 will extend and retract synchronously with the reciprocating motion of the placement box 12. At this time, the potting compound will not accumulate and remain locally in the casting box, but can spread evenly with the movement of the placement box 12. At the same time, the compound can fully penetrate into the gap between the membrane fibers, effectively eliminating the sealing dead corner.
