Abstract
Description
Technical Field
[0001] This utility model relates to the field of filtration technology, and in particular to a foldable high-efficiency filter. Background Technology
[0002] In industrial production, air purification, water treatment, and other fields, filters are key equipment for separation and purification, and their performance directly affects production efficiency, product quality, and environmental safety. With the increasing demands for filtration precision in modern industry (such as the need for removal of micron- and even nanometer-sized impurities in the electronics and semiconductor industry), as well as the need to optimize logistics, transportation, and storage costs;
[0003] Chinese Patent Publication No. CN220715224U discloses a folded composite filter, aiming to overcome the defects of complex structure and difficult transportation in the prior art. It is mainly achieved through the following technical solution: A folded composite filter includes a filter body, which includes a filter element and a frame. The frame includes a first frame and a second frame that are slidably connected and fixed by plastic rivets. The filter element includes a filter paper layer, two mesh covering layers and an edge layer. The filter element is also provided with several positioning strips. The first frame and the second frame are provided with support strips and limiting strips. The filter element is provided with support holes that cooperate with the support strips and positioning holes that cooperate with the limiting strips. The filter provided by this application occupies little space, is convenient and simple to package, controls costs, and plays a role in energy saving and environmental protection.
[0004] The aforementioned patent documents still have the following defects in practice:
[0005] The filter element, positioning strip, and frame are connected as a single unit (e.g., rigid fit between support holes and support clips, and water-based adhesive fixation), without employing a detachable modular structure. This design prevents the filter element from being individually removed and replaced. Utility Model Content
[0006] The main objective of this invention is to provide a foldable high-efficiency filter that can effectively solve the problems mentioned above.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] A foldable high-efficiency filter includes two support plates. The two support plates are provided with a moving mechanism on one side close to each other. The moving mechanism is provided with an opening and closing mechanism at the lower part, and a telescopic mechanism is provided at the rear part of the opening and closing mechanism. Several filter plates are provided in the middle of the opening and closing mechanism.
[0009] Preferably, the moving mechanism includes two square sleeves, the left sides of the two square sleeves are jointly disposed on the right side of the left support plate, the inner surface of the square sleeves is provided with a moving rod, and the right side of the square sleeves is provided with a threaded rod.
[0010] Preferably, the moving mechanism includes two limiting frames one and two limiting frames two, the two limiting frames one being respectively disposed on the side of the two support plates close to each other, and the two limiting frames two being respectively disposed on the side of the two support plates close to each other.
[0011] Preferably, the telescopic mechanism includes five support rods, each of which has a fixing block at both the top and bottom. Except for the rightmost fixing block, each support rod has a telescopic sleeve on its right side and a telescopic rod on its left side, except for the leftmost fixing block. The telescopic rods are located inside the corresponding telescopic sleeves.
[0012] Preferably, the opening and closing mechanism includes several support rods 2, with square blocks at the lower part of the leftmost and rightmost support rods 2, and cylindrical blocks at the lower part of the other support rods 2. The outer surfaces of several support rods 2 are provided with hinge 1 and hinge 2.
[0013] Preferably, the leftmost support rod 2 is provided with a movable plate 1 on its upper part, the rightmost support rod 2 is provided with a movable plate 2 on its upper part, and the other support rods 2 are provided with a movable plate 1 and a movable plate 2 on their upper parts.
[0014] Preferably, the middle part of the support rod is connected to hinge one and hinge two, and several hinges one and hinge two are alternately arranged in an accordion shape.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. In this embodiment, hinge one and hinge two in the opening and closing mechanism are arranged alternately in an accordion shape. When unfolded, they can drive several filter plates to form a continuous and complete large-area filter surface, which greatly increases the fluid processing capacity per unit time and meets the high-precision filtration requirements of micron-level and even nano-level impurities in industrial production, electronic semiconductors and other fields. This avoids efficiency bottlenecks caused by insufficient filtration area. The telescopic mechanism, through the cooperation of telescopic rod and telescopic sleeve, combined with the rigid connection of fixed block, can strictly limit the maximum unfolding angle of the opening and closing mechanism to prevent excessive stretching and damage to the hinge structure. At the same time, the interaction between limit frame one and limit frame two in the moving mechanism ensures that the two support plates move smoothly without deviation, so that the unfolding angle of all filter plates is consistent, avoiding uneven local filtration load and ensuring stable overall filtration effect.
[0017] 2. In this embodiment, unlike the existing technology where the filter element and frame are integrated and fixed, the filter plate of this device is independently set in the middle of the opening and closing mechanism. There is no need to disassemble the entire frame. The filter plate can be removed or replaced individually by simply adjusting the opening and closing mechanism. This avoids the scrapping of the entire equipment due to the failure of a local filter element, greatly reducing maintenance costs and waste of consumables. The unfolding and storage process only requires two steps: loosening or tightening the threaded rod and pushing or pulling the support plate. No professional tools or complicated training are required, and ordinary workers can complete the task quickly. In addition, the design of the square block and the second limiting frame can prevent the moving plate from getting stuck when folding, further improving the smoothness of operation. It is suitable for flexible use in various scenarios such as industrial production lines, air purification equipment, and water treatment systems. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] Example 1, as Figure 1 - Figure 2 As shown, a foldable high-efficiency filter has two support plates 1. The two support plates 1 are provided with a moving mechanism 2 on one side close to each other. The lower part of the moving mechanism 2 is provided with an opening and closing mechanism 5. The rear part of the opening and closing mechanism 5 is provided with a telescopic mechanism 4. The middle part of the opening and closing mechanism 5 is provided with several filter plates 3.
[0026] In this embodiment, during implementation, the moving mechanism 2 is adjusted, and the two support plates 1 are pulled apart by grasping one side of the support plate 1. When pulled apart, the opening and closing mechanism 5 drives the opening and closing angle of several filter plates 3 to increase. The telescopic mechanism 4 limits and provides structural support for the folding and unfolding of the opening and closing mechanism 5, so that the opening and closing mechanism 5 can be folded and stored or unfolded smoothly. The filter plates 3 are set in the middle of the opening and closing mechanism 5. When the opening and closing mechanism 5 is unfolded, it can form a large effective filtration area to ensure a good filtration effect. At the same time, in conjunction with the folding function of the opening and closing mechanism 5, it can also be folded together when stored, without affecting the storage convenience of the device.
[0027] To fix the filter plate 3 after it is unfolded, refer to... Figure 3 The moving mechanism 2 includes two square sleeves 21. The left parts of the two square sleeves 21 are jointly arranged on the right side of the left support plate 1. The inner surface of the square sleeves 21 is provided with a moving rod 23. The right side of the square sleeves 21 is provided with a threaded rod 22. The moving mechanism 2 includes two limiting frames 1 24 and two limiting frames 25. The two limiting frames 1 24 are respectively arranged on the side of the two support plates 1 close to each other. The two limiting frames 25 are respectively arranged on the side of the two support plates 1 close to each other.
[0028] During implementation, first loosen the threaded rod 22 on the right side of the square sleeve 21, allowing the moving rod 23 to slide freely within the square sleeve 21. Then, grasp one of the support plates 1 and pull the two support plates 1 apart. Under the pulling force, the moving rod 23 extends to the right along the inside of the square sleeve 21. At the same time, the first limiting frame 24 and the second limiting frame 25 cooperate with each other to precisely limit the movement direction of the two support plates 1, preventing deviation or jamming during movement and ensuring the smooth unfolding of the overall structure.
[0029] To ensure that the unfolding angle of filter plates 3 is consistent, please refer to... Figure 5 The telescopic mechanism 4 includes five support rods 41. Each support rod 41 has a fixing block 42 at both the top and bottom. Except for the rightmost fixing block 42, each support rod 41 has a telescopic sleeve 44 on its right side. Except for the leftmost fixing block 42, each support rod 41 has a telescopic rod 43 on its left side. The telescopic rod 43 is located inside the corresponding telescopic sleeve 44.
[0030] During implementation, pulling the support plate 1 causes the opening and closing mechanism 5 to unfold. The telescopic rod 43 on the left side of the leftmost fixed block 42 gradually extends from the adjacent telescopic sleeve 44, and the distance between each support rod 41 increases synchronously. The rigid connection of the fixed block 42 limits the maximum unfolding angle of the opening and closing mechanism 5, preventing damage to the hinge structure due to excessive stretching. When it is necessary to store, push the two support plates 1 in the opposite direction, and the telescopic rod 43 retracts into the telescopic sleeve 44. The opening and closing mechanism 5 retracts under the folding action of the hinge structure, and the filter plate 3 folds and overlaps accordingly. At this time, tightening the threaded rod 22 can fix the position of the moving rod 23 and complete the storage.
[0031] Example 2: To unfold filter plate 3, refer to... Figure 4 The opening and closing mechanism 5 includes several support rods 55. The leftmost and rightmost support rods 55 are provided with square blocks 52 at their lower parts, and the other support rods 55 are provided with cylindrical blocks 53 at their lower parts. The outer surfaces of several support rods 55 are provided with hinges 51 and hinges 54. The leftmost support rod 55 is provided with a movable plate 56 at its upper part, the rightmost support rod 55 is provided with a movable plate 57 at its upper part, and the other support rods 55 are provided with movable plates 56 and movable plates 57 at their upper parts. The middle part of the support rod 41 is connected to the hinges 51 and hinges 54. Several hinges 51 and hinges 54 are arranged alternately in an accordion shape.
[0032] During implementation, because the middle of support rod 41 is connected to hinge 51 and hinge 54, and hinges 51 and 54 are arranged alternately in an accordion shape, adjacent support rods 55 open and close at an angle through the hinge structure. At this time, the included angle between several support rods 55 gradually increases, causing the filter plate 3 installed in the middle to unfold synchronously, forming a continuous and complete filter surface. The filter plate 3 is set in the middle of hinges 51 and 54. When hinges 51 and 54 unfold, a large-area filter area is formed, effectively improving the filter efficiency per unit time. The filter plate 3 has a folding design and can be stacked and compressed to one-third of its original volume when stored, greatly reducing storage space. In addition, the square blocks 52 at the bottom of the leftmost and rightmost support rods 55 can cooperate with the limiting frame 25 to keep the moving plate 56 and the moving plate 57 at a certain angle when unfolded, so that the moving plate 56 and the moving plate 57 can be folded smoothly without getting stuck. The cylindrical block 53 at the bottom of the middle support rod 55 supports the opening and closing mechanism 5 to ensure the balance of the device.
