Description

Technical Field

[0001] The utility model belongs to the technical field of food production equipment, and particularly relates to a membrane core replacement auxiliary device. Background Art

[0002] Membrane equipment is used for process experiments such as concentration, desalination, decolorization, purification, clarification, and sterilization of liquids. It is widely used in the pharmaceutical, food and beverage, chemical, plant extraction, and environmental water treatment industries. These membrane devices typically include plate-and-frame and circular tubular types, depending on the membrane assembly structure. In the design of circular tubular membrane equipment, to balance production capacity, performance, and floor space, the membrane assembly is typically composed of multiple membrane tubes arranged in a matrix, with multiple membrane cores typically located within each membrane tube. The membrane core needs to be replaced after a certain period of use. In the prior art, manual disassembly and installation are primarily performed. For example, Chinese utility model patent application number CN201621155277.2 discloses a reverse osmosis membrane disassembly tool. The tool first rotates the shaft so that the length of the first branch rod aligns with the length of the main rod. A screw is screwed into the screw hole of the end cap. The prying portion is then shaken to loosen the end cap from the pressure shell. The end cap is then pulled out by pulling the main rod. The shaft is then rotated so that the length of the second branch rod aligns with the length of the main rod. The main rod is rotated so that the hook engages the notch on the membrane element. The membrane element is then pulled out by pulling the main rod. This method primarily involves manually holding the disassembly tool and rotating the shaft to disassemble the membrane core. However, in actual production sites, membrane cores are typically large (e.g., 1.2 m × 20 cm in length × diameter) and tightly connected to connectors. Manual disassembly alone is inefficient and poses risks such as difficulty, falling parts during disassembly, and safety hazards associated with working at height. Summary of the Invention

The terms used in the specification herein are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Please see Figures 1 to 5In a specific embodiment of the present application, a membrane core replacement auxiliary device includes: a movable lifting platform 100; a guide component, wherein the guide component is arranged on the movable lifting platform 100, the guide component includes a guide groove 210, a first radial adjustment mechanism 220, and a first axial adjustment mechanism 230, the first radial adjustment mechanism 220 is transmission-connected to the first axial adjustment mechanism 230, and the guide groove 210 is arranged on the first axial adjustment mechanism 230; a membrane core extraction component, the membrane core extraction component includes a gantry frame 310, a second radial adjustment mechanism 320, an axial movement mechanism and a membrane core clamping mechanism 340, the gantry frame 310 is arranged on the movable lifting platform 100, the second radial adjustment mechanism 320 is arranged on the top of the gantry frame 310, the axial movement mechanism is transmission-connected to the second radial adjustment mechanism 320, the membrane core clamping mechanism 340 is arranged on the axial movement mechanism, and the axial movement mechanism is used to drive the membrane core clamping mechanism 340 to move axially along the guide groove 210.

[0032] At the production site, membrane group equipment is usually in multiple groups, and is divided into different membrane group equipment according to function, such as ultrafiltration membrane group, nanofiltration membrane group, microfiltration membrane group, etc., which are usually set in different positions, occupy a large area, and some are also high. In order to adapt to the different positions of membrane group equipment, the guide assembly and membrane core extraction assembly are integrated on the movable lifting platform 100. The movable lifting platform 100 includes a lifting platform and a rotating wheel set on the lifting platform. The lifting platform can be selected as a scissor-type lifting platform, a guide rail lifting platform, a chain lifting platform, etc., and the scissor-type lifting platform is preferred in this application. The main function of the guide groove 210 is to support the membrane core 520 and slide along the axial direction of the membrane core 520, cooperating with the membrane core extraction assembly to extract or push the membrane core 520. Since the membrane core 520 is usually cylindrical, the guide groove 210 is semi-cylindrical. If used in some clean environments, in order not to contaminate the membrane core 520, the guide groove 210 is also preferably made of a material that meets the requirements of the production environment. For example, the guide groove 210 in the food industry is preferably made of food-grade stainless steel. The first radial adjustment mechanism 220 is used to adjust the guide groove 210 to slide along its radial direction, and the first axial adjustment mechanism 230 is used to adjust the guide groove 210 to slide along its axial direction. Under the joint adjustment action of the first radial adjustment mechanism 220 and the first axial adjustment mechanism 230, the guide groove 210 is aligned with the end face of the membrane tube 510. In this way, when the membrane core 520 is pulled out, it can directly slide into the guide groove 210 without manual support, and will not cause the membrane core 520 to tilt, fall, etc., which is safer and more labor-saving. The membrane core 520 is mainly extracted by the membrane core extraction assembly. The gantry frame 310 is set on the movable lifting platform 100, and the membrane core extraction assembly is set on the gantry frame 310. The position of the membrane core clamping mechanism 340 can be adjusted by the second radial adjustment mechanism 320 and the axial movement mechanism, so that the membrane core clamping mechanism 340 can accurately grasp the connector 530 on the membrane core 520, and then the axial movement mechanism drives the membrane core clamping mechanism 340 to extract the membrane core 520. Similarly, when installing the membrane core 520, the membrane core clamping mechanism 340 grasps the connector 530 on the membrane core 520 and pushes the membrane core 520 into the membrane shell. This method of automatically extracting or pushing the membrane core 520 can greatly save manpower and can be completed without manual operation; and the guide groove 210 supports the membrane core 520 exposed outside the membrane shell, which can avoid the risk of accessories falling or personnel safety during disassembly; the membrane core 520 is supported, grasped and positioned by the guide assembly and the membrane core extraction assembly, with a high degree of mechanization, saving manpower and high work efficiency.

[0033] The working process is as follows: when replacing the membrane core 520, the movable lifting platform 100 is moved to the position of the membrane group where the membrane core needs to be replaced, and the height of the movable lifting platform 100 is adjusted to perform rough adjustment of the position. The blind cover and the permeate end cover of the membrane tube 510 to be replaced are removed, and then the first radial adjustment mechanism 220 and the first axial adjustment mechanism 230 are adjusted to align the guide groove 210 with one end of the membrane tube 510 (either the blind cover end or the permeate end). When the membrane core 520 is pushed from the other end to expose the connector 530 from the membrane tube 510, the second radial adjustment mechanism 320 and the axial movement mechanism are adjusted to enable the membrane core clamping mechanism 340 to clamp the connector 530. At the same time, the axial movement mechanism is adjusted. At this time, the membrane core clamping mechanism 340 moves along the axial direction of the guide groove 210 while pulling out the membrane core. At this time, the membrane core 520 that has slipped out of the membrane tube 510 is carried in the guide groove 210. At this time, the connector 530 and the membrane core 520 are separated to complete the disassembly of the membrane core 520. When installing a new membrane core 520, align the guide groove 210 and one end of the membrane tube 510 in the same manner as when removing the membrane core 520, place the new membrane core 520 in the guide groove 210, adjust the second radial adjustment mechanism 320 and the axial movement mechanism so that the membrane core clamping mechanism 340 can clamp the connector 530, and adjust the axial movement mechanism at the same time. While the membrane core clamping mechanism 340 moves axially along the guide groove 210, the membrane core 520 is pulled and pushed into the membrane tube 510, and then the blind cover and the permeate end cover are installed to complete the installation of the new membrane core.

[0034] In a preferred embodiment, the first radial adjustment mechanism 220 includes a radially movable plate 221, a guide rod 222, a first radial drive screw 223 and a first drive motor 224. The guide rod 222 passes through the radially movable plate 221 along a direction parallel to the radial direction of the guide groove 210 and is slidingly connected to the radially movable plate 221, so that the radially movable plate 221 moves radially along the guide groove 210. The first radial drive screw 223 passes through the radially movable plate 221 and cooperates with the radially movable plate 221 for transmission. The first drive motor 224 is transmission-connected to the first radial drive screw 223.

[0035] As described above, the first radial adjustment mechanism 220 is used to adjust the guide groove 210 to slide along the radial direction of the guide groove 210. The guide groove 210 is connected to the radial movable plate 221 through the first axial adjustment mechanism 230. In other words, the radial movement of the guide groove 210 is consistent with the radial movement of the radial movable plate 221. The radial movable plate 221 is set on the upper surface of the movable lifting platform 100. A threaded through hole is set on the radial movable plate 221. The direction of the threaded through hole is consistent with the radial direction of the guide groove 210 and remains horizontal. The first radial drive screw 223 passes through the threaded hole and the two are threadedly matched for transmission. The radial movable plate 221 is provided with at least one through hole. The through hole is in the same plane as the threaded hole and remains parallel. A guide rod 222 is set in the through hole. The guide rod 222 passes through the through hole and the radial movable plate 221 can move along the guide rod 222. When the first drive motor 224 drives the first radial drive screw 223 to rotate, under the action of the threaded transmission, the first radial drive screw 223 drives the radial movable plate 221 to move along the guide rod 222, that is, the radial movable plate 221 moves radially along the guide groove 210 in the horizontal direction, thereby realizing the position adjustment of the guide groove 210 in its radial direction.

[0036] In another specific embodiment of the present application, a sliding groove is arranged axially on the radial movable plate 221, and the first axial adjustment mechanism 230 includes an axial movable plate 231, a first axial driving screw 232 and a second driving motor 233. The axial movable plate 231 is arranged in the sliding groove, the first axial driving screw 232 passes through the axial movable plate 231 and is in transmission cooperation with the axial movable plate 231, and the second driving motor 233 is transmission connected to the first axial driving screw 232 for driving the axial movable plate 231 to move along the sliding groove.

[0037] In the process of aligning the guide groove 210 with the membrane tube 510, in addition to adjusting the radial position of the guide groove 210, the axial position must also be adjusted. The guide groove 210 is set on the first axial adjustment machine, and the axial position is adjusted by the first axial adjustment mechanism 230. Specifically, the guide groove 210 is set on the axial movable plate 231, and the axial movable plate 231 is set on the radial movable plate 221. A threaded through hole is set on the axial movable plate 231. The direction of the threaded through hole is consistent with the axial direction of the guide groove 210. The first axial drive screw 232 passes through the threaded through hole and the two are threadedly matched for transmission. When the second drive motor 233 drives the first axial drive screw 232 to rotate, under the action of the threaded transmission, the first axial drive screw 232 drives the axial movable plate 231 to move along the axial direction of the guide groove 210. In order to keep the moving path of the axially movable plate 231 straight, sliding grooves are set on both sides of the axially movable plate 231 parallel to the axis of the guide groove 210, so that the axially movable plate 231 slides in the sliding groove, and then the guide groove 210 moves axially along the guide groove 210 in the horizontal plane with the axially movable plate 231, thereby realizing the position adjustment of the guide groove 210 in its axial direction.

[0038] The position of the membrane core clamping mechanism 340 is mainly adjusted through the second radial adjustment mechanism 320 and the axial moving mechanism. In a preferred embodiment, the second radial adjustment mechanism 320 includes a radial transmission groove 321, a second radial drive screw 322 and a third drive motor. The radial transmission groove 321 is arranged at the top of the gantry body 310, and the second radial drive screw 322 passes through the radial transmission groove 321 and cooperates with the axial moving mechanism. The third drive motor is connected to the second radial drive screw 322 for driving the axial moving mechanism to move radially along the guide groove 210; the guide groove 210 is fixed on the axial moving plate 231.

[0039] The second radial adjustment mechanism 320 is arranged on the top beam of the gantry. The top beam is perpendicular to the axial direction of the guide groove 210. There are usually two top beams. That is, the second radial adjustment mechanism 320 includes radial transmission grooves 321, a second radial drive screw 322, and a third drive motor. The radial transmission groove 321 opens downward and has a threaded through hole extending along the length of the radial transmission groove 321. The threaded through hole is arranged horizontally. The second radial drive screw 322 passes through the threaded through hole. The axial movement mechanism is threadedly connected to the second radial drive screw 322 through the lower opening of the radial transmission groove 321. When the third drive motor drives the second radial drive screw 322 to rotate, the second radial drive screw 322 drives the axial movement mechanism to move along the axial direction of the guide groove 210 under the action of the threaded transmission. Since the membrane core clamping mechanism 340 is arranged on the axial movement mechanism, when the axial movement mechanism moves along the radial direction of the guide groove 210, the radial direction of the membrane core clamping mechanism 340 is adjusted.

[0040] At the same time, the membrane core clamping mechanism 340 must also be moved in the axial direction. Furthermore, the axial movement mechanism includes an axial crossbeam, a second axial drive screw 332, and a fourth drive motor 333. The axial crossbeam is in transmission cooperation with the radial transmission groove 321. The second axial drive screw 332 passes through the axial crossbeam and is in transmission cooperation with the membrane core clamping mechanism 340. The fourth drive motor 333 is in transmission connection with the second axial drive screw 332 to drive the membrane core clamping mechanism 340 to move axially along the guide groove 210. The two ends of the axial crossbeam are respectively arranged on the two radial transmission grooves 321. A threaded through hole is opened in the axial crossbeam along the axial direction of the guide groove 210. The second axial drive screw 332 passes through the threaded through hole. The membrane core clamping mechanism 340 is threadedly connected to the second axial drive screw 332. When the fourth drive motor 333 drives the second axial drive screw 332 to rotate, under the action of the threaded transmission, the second axial drive screw 332 drives the membrane core clamping mechanism 340 to move along the axial direction of the guide groove 210, thereby realizing the movement of the membrane core clamping mechanism 340 in the axial direction. Not only can the axial position of the membrane core clamping mechanism 340 be adjusted, but also when the membrane core clamping mechanism 340 clamps the connector 530, the membrane core 520 can be pulled out through the axial movement of the membrane core clamping mechanism 340 (when installing the membrane core, the membrane core is pushed into the membrane tube 510).

[0041] In order to achieve the clamping of the connector 530, the membrane core clamping mechanism 340 includes a first claw 341, a second claw 342, a lifting slide 343, a plurality of connecting rods 344, and a climber 345. The first claw 341 and the second claw 342 are hinged to each other, and are rotatably connected to the climber 345 through the connecting rod 344 respectively. The climber 345 is transmission-connected to the lifting slide 343. The climber 345 can slide up and down along the lifting slide 343, driving the first claw 341 and the second claw 342 to rotate relative to each other around the hinge part. One end of the lifting slide 343 is transmission-connected to the second axial drive screw 332. Specifically, the climber 345 includes a housing and a climbing drive motor. The lifting slide 343 extends through the housing and is slidably connected to the housing. Specifically, a pair of friction wheels are disposed inside the housing. The friction wheels are clamped on either side of the lifting slide 343 and are in rolling connection with the lifting slide 343. The friction wheels are in transmission connection with the climbing drive motor, which can drive the friction wheels to roll in different directions, causing the housing to move up and down along the lifting slide 343. The upper ends of the pair of traction connecting rods 344 are respectively connected to the sides of the housing, and the lower ends are respectively hinged to the outer surfaces of the first and second claws 341, 342, which are hinged together. When the climber 345 slides upward along the lifting slide 343, the traction connecting rods 344 move upward. The location where the traction connecting rods 344 connect to the two claws opens to the sides due to the traction force, causing the first and second claws 341, 342 to open. When the membrane core clamping mechanism 340 moves to the position of the connector 530, the climber 345 slides downward along the lifting slide bar 343, pulling the connecting rod 344 to rotate outward, so that the first claw 341 and the second claw 342 are closed, thereby clamping the connector 530.

[0042] To prevent axial displacement of the connector 530 and thus unstable clamping when the connector 530 is clamped and pulled or pushed, a clamping groove 349 is further provided on the opposite side of the first clamping claw 341 and the second clamping claw 342. The clamping groove 349 is used to prevent axial displacement of the clamped object during the clamping process. When the first clamping claw 341 and the second clamping claw 342 clamp the connector 530, the connector 530 is fixed in the clamping groove 349, thus preventing axial displacement and ensuring a more stable clamping.

[0043] When the connector 530 needs to be clamped, the height of the two clamping claws must be adjusted. Furthermore, the membrane core clamping mechanism 340 also includes a fixed seat 346, a lifting cylinder 347, and a connecting plate 348. The top of the fixed seat 346 is slidably mounted on the axial crossbeam. One end of the lifting cylinder 347 is mounted on the bottom of the fixed seat 346, and the other end is fixedly connected to the upper portion of the connecting plate 348. The bottom of the connecting plate 348 is fixedly connected to the lifting slide 343. The fixed seat 346 is used to thread the membrane core clamping mechanism 340 to the second axial drive screw 332 within the axial crossbeam. The lifting cylinder 347 can drive the connecting plate 348 to move up and down by lifting. Since the connecting plate 348 is connected to the lifting slide 343, the height of the two clamping claws can be adjusted during the lifting process of the lifting cylinder 347, allowing for more flexible grasping and clamping of the connector 530.

[0044] As mentioned above, when the membrane core 520 is pulled out, it can slide directly into the guide groove 210. Similarly, when installing the membrane core, the membrane core can be placed in the guide groove 210 first, and then pushed into the membrane tube 510. To avoid scratching the membrane core 520, the inner surfaces of the guide groove 210 and the membrane tube 510 should be aligned, especially the lower part should be on the same horizontal plane. Therefore, the height of the guide groove 210 must be precisely adjusted. Therefore, in a preferred embodiment, the axial movable plate 231 is also provided with at least a pair of height fine-tuning mechanisms 410. The height fine-tuning mechanisms 410 are distributed at both ends of the guide groove 210 and connected to the axial movable plate 231. The operating principle of height fine-tuning mechanism 410 is similar to that of a height fine-tuning support device disclosed in Chinese utility model patent application number CN201521021099.X. Specifically, it comprises two upper and lower adjustment blocks connected by an inclined plane. The upper end of upper adjustment block 411 is provided with a support plane and is vertically movable with the base. One side of the lower adjustment block is connected to a horizontal telescopic mechanism, which drives the lower adjustment block to move horizontally, causing vertical relative displacement between the two adjustment blocks via the inclined plane structure. In this application, the upper end of upper adjustment block 411 is fixedly connected to the bottom surface of guide groove 210, while the lower end of lower adjustment block 412 is in sliding contact with axially movable plate 231. At the same time, the present application improves the horizontal telescopic mechanism. An adjusting screw 413 is arranged in the horizontal direction in the lower adjusting block 412. The other end of the adjusting screw 413 is connected to the fifth driving motor 414. The fifth driving motor 414 drives the adjusting screw 413 to rotate, thereby driving the lower adjusting block 412 to reciprocate along the axial moving plate 231, thereby precisely adjusting the horizontal height of the two ends of the guide groove.

[0045] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
