Description

Technical Field

[0001] The utility model belongs to the technical field of membrane separation, and more specifically, relates to a spiral wound membrane concentration and separation structure. Background Technique

[0002] A membrane is an inorganic or polymer material with a special selective separation function. According to its shape, it can be divided into flat membranes, tubular membranes, hollow fiber membranes, and spiral wound membranes. It can separate a fluid into two non - communicating parts, allowing one or several substances to pass through while separating other substances. Membrane technology is the preferred technology for environmental protection and environmental governance and is also playing an important role in the food industry;

[0003] However, when replacing the spiral wound membrane, since the outer wall of the feed pipe contacts the raw material, during filtration, impurities or other substances may adhere to the outer wall of the feed pipe. After replacing a brand - new spiral wound membrane filter element, the impurities and other substances adhered to the outer wall of the feed pipe may cause a decrease in the filtration efficiency of the new spiral wound membrane filter element, thereby reducing the service life of the spiral wound membrane and significantly increasing the operating cost;

[0004] To solve the above problems, a spiral wound membrane concentration and separation structure is proposed in this application. Content of the Utility Model

[0005] In view of the problems in the related art, the utility model provides a spiral wound membrane concentration and separation structure to overcome the above - mentioned technical problems existing in the prior related art.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A spiral wound membrane concentration and separation structure includes a device main body. A filter pipe is fixedly connected to the device main body. A connection plug is movably connected to the top of the filter pipe. A connecting piece is detachably connected to the bottom of the connection plug. A limiting block is fixedly connected to the inner side wall of the connecting piece. A sliding groove is opened in the limiting block. A sliding block is slidably connected to the inner side wall of the limiting block. A compression spring is fixedly connected to the inner side wall of the sliding block. One end of the compression spring far from the inner side wall of the sliding block is fixedly connected to a connecting rod. One end of the connecting rod far from the compression spring is fixedly connected to an arc - shaped plate.

[0008] Preferably, a slot is opened at the top of the connecting piece. By providing the slot, it is convenient to increase the contact area between the inner side wall of the connecting piece and the outer side wall of the connecting ring, thereby increasing the friction force.

[0009] Preferably, a return spring is fixedly connected to the top of the connecting piece, and a resistance plate is fixedly connected to the end of the return spring away from the connecting piece. By providing the return spring and the resistance plate, it is convenient to squeeze the connecting plug after the connecting plug and the connecting piece are connected, so that the connection between the connecting plug and the connecting piece is tighter.

[0010] Preferably, the top of the contact plate is fixedly connected to a connecting seat, and the outer wall of the connecting seat is rotatably connected to a buckle. By providing the connecting seat and the buckle, it is convenient to engage the connecting ring, thereby preventing the connecting plug and the connecting piece from detaching when external force is applied to the connecting plug.

[0011] Preferably, a connecting ring is fixedly connected to the bottom of the connecting plug. By providing the connecting ring, the connection stability between the connecting plug and the connecting piece can be improved.

[0012] Preferably, a limit plate is fixedly connected to the top of the connecting ring. By providing the limit plate, the connecting plug is prevented from rotating during use, thereby preventing the connecting plug from detaching from the connecting piece.

[0013] In summary, the technical effects and advantages of the utility model are as follows: the roll-type membrane concentration and separation structure, through the coordinated use of the limit block, the slide groove, the slider, the extrusion spring, the connecting rod, and the arc plate, is convenient for removing the impurities or unnecessary substances filtered inside the filter element when disassembling the roll-type membrane filter element, and preventing impurities or other substances from entering the new filter element through the pipeline, thereby causing the filtering effect of the new filter element to decrease;

[0014] By using the connecting ring, the limit plate, the slot, the return spring and the resistance plate in coordination, the tightness of the connection between the connecting plug and the connecting piece can be improved to avoid the connection plug and the connecting piece being separated when external force is applied to the connecting plug, thereby reducing the replacement efficiency of the filter element.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Refer to Figures 1-3 , a roll-type membrane concentration and separation structure, including an equipment main body 1, a filter pipeline 2 is fixedly connected to the equipment main body 1, a connecting plug 3 is movably connected to the top of the filter pipeline 2, the inner side wall of the connecting plug 3 is fixedly connected to the outer side wall of the feed pipe, the bottom of the connecting plug 3 is detachably connected to a connecting piece 4, the inner side wall of the connecting piece 4 is fixedly connected to a limiting block 5, there are three limiting blocks 5, and the three limiting blocks 5 are evenly distributed in a circumferential array on the inner side wall of the connecting piece 4. Sliding grooves 6 are respectively opened in the three limiting blocks 5. The cross-sections of the three sliding grooves 6 are all trapezoids with the upper base smaller than the lower base. Sliders 7 are respectively slidably connected to the inner side walls of the three limiting blocks 5. The outer side walls of the three sliders 7 respectively fit with the inner side walls of the three limiting blocks 5. The inner side walls of the three sliders 7 are respectively fixedly connected to extrusion springs 8. One ends of the three extrusion springs 8 away from the inner side walls of the three sliders 7 are respectively fixedly connected to connecting rods 9. One ends of the three connecting rods 9 away from the three extrusion springs 8 are respectively fixedly connected to arc plates 10, and when the three arc plates 10 are connected end to end, they form a ring. When replacing the filter element, the operator needs to first remove the connecting plug 3, and at the same time, the feed pipe fixedly connected to the connecting plug 3 is also removed. Since the extrusion spring 8 itself has elasticity, under the action of the three extrusion springs 8, the side of the three arc plates 10 close to the feed pipe always fits with the outer side wall of the feed pipe, so as to scrape the impurities adhered to the outer side wall of the feed pipe. As the feed pipe rises, the accumulation of impurities increases, and the outer side walls of the three arc plates 10 and the outer side wall of the feed pipe gradually move away as the impurities accumulate;

[0023] At this time, the frictional force between the three arc plates 10 and the feed pipe will drive the three sliders 7 to gradually move towards the top of the three limiting blocks 5. Since the cross-sections of the three sliding grooves 6 are all trapezoids, as the three sliders 7 move upward, the distance between the three sliders 7 and the feed pipe gradually decreases, thereby pushing the three connecting rods 9 and the three arc plates 10 to always fit with the outer side wall of the feed pipe, avoiding the separation of the three arc plates 10 from the outer side wall of the feed pipe due to the accumulation of impurities, and thus avoiding the omission of impurities.

[0024] Refer toFigure 4 , a slot 13 is provided at the top of the connecting member 4. The center of the slot 13 coincides with the center of the top of the connecting member 4. A return spring 14 is fixedly connected to the top of the connecting member 4. The return spring 14 is located inside the slot 13. There are four return springs 14, and the four return springs 14 are evenly distributed in a circumferential array inside the slot 13. One end of the four return springs 14 away from the connecting member 4 is fixedly connected to a contact plate 15. The contact plate 15 is located inside the slot 13. The outer side wall of the contact plate 15 fits with the inner side wall of the slot 13. When the contact plate 15 is squeezed by an external force, it will exert pressure on the four return springs 14, causing the four return springs 14 to contract.

[0025] Refer to Figure 4 , a connecting seat 16 is fixedly connected to the top of the contact plate 15. There are four connecting seats 16, and the positions of the four connecting seats 16 correspond to the positions of the four return springs 14 one by one. A buckle 17 is rotatably connected to the outer side wall of the connecting seat 16. The cross-section of the buckle 17 is hook-shaped, which is convenient for connecting the connecting member 4.

[0026] Refer to Figure 4 , a connecting ring 11 is fixedly connected to the bottom of the connecting plug 3. When the connecting plug 3 is connected to the connecting member 4, the connecting ring 11 squeezes the contact plate 15, causing the four return springs 14 to contract. Further, the outer side walls of the four buckles 17 are in contact with the inner side wall of the connecting member 4. As the contact plate 15 moves downward, the four buckles 17 gradually enter the inside of the slot 13. Under the action of the contact of the inner side wall of the connecting member 4, the horizontal angles of the four buckles 17 tend to be vertical, so as to hook the connecting ring 11, preventing the connecting plug 3 and the connecting member 4 from separating during use. At the same time, when the force applied to the connecting plug 3 is stopped, the four return springs 14 lift the connecting ring 11 under the action of their own elastic force, so that the top of the connecting ring 11 is in contact with the outer side walls of the four buckles 17, thus preventing the four buckles 17 from separating from the connecting ring 11 during use.

[0027] Refer to Figure 4 , a limiting plate 12 is fixedly connected to the top of the connecting ring 11. The inner side wall of the limiting plate 12 is adapted to the outer side wall of the buckle 17. And there are four limiting plates 12, and the positions of the four limiting plates 12 correspond to the positions of the four buckles 17 one by one, so as to engage the four buckles 17, preventing the connecting plug 3 or the connecting member 4 from rotating alone, resulting in the separation of the connecting plug 3 and the connecting member 4.

[0028] Working principle: Align the positions of the limit plate 12 and the buckle 17, insert the connecting plug 3 and the feed pipe into the interior of the connecting piece 4, during the insertion process, the connecting ring 11 squeezes the contact plate 15, so that the contact plate 15 moves downward, compresses the reset spring 14, and drives the buckle 17 to move toward the inside of the slot 13. When the inner side wall of the connecting piece 4 contacts the outer side wall of the buckle 17, the horizontal angle of the buckle 17 gradually becomes vertical, and the outer side wall of the buckle 17 gradually fits with the outer side wall of the connecting ring 11. After stopping the pressure, under the action of the elastic force of the reset spring 14 itself, the contact plate 15 lifts the connecting ring 11, so that the top of the connecting ring 11 fits tightly with the outer side wall of the buckle 17.

[0029] When replacing the filter element, the operator needs to first remove the connecting plug 3, and at the same time remove the feed pipe fixedly connected to the connecting plug 3. Since the extrusion spring 8 itself has elasticity, under the action of the three extrusion springs 8, the side of the three arc plates 10 close to the feed pipe is always in contact with the outer wall of the feed pipe, so as to scrape the impurities stuck to the outer wall of the feed pipe. As the feed pipe rises, the accumulation of impurities increases, and the outer walls of the three arc plates 10 and the outer wall of the feed pipe gradually move away from each other as the impurities accumulate.

[0030] At this time, the friction between the three arc plates 10 and the feed pipe will drive the three sliders 7 to gradually move toward the top of the three limit blocks 5. Since the cross-sections of the three slide grooves 6 are all trapezoidal, as the three sliders 7 move upward, the distance between the three sliders 7 and the feed pipe gradually decreases, thereby pushing the three connecting rods 9 and the three arc plates 10 to always fit with the outer wall of the feed pipe, avoiding the separation of the three arc plates 10 from the outer wall of the feed pipe due to the accumulation of impurities, thereby avoiding the leakage of impurities.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
