Description

Technical Field

[0001] This utility model is a quick-install filter, belonging to the field of filter technology. Background Technology

[0002] Filters are indispensable devices in pipeline systems of hydraulics, pneumatics, water treatment, and chemical industries. Their core function is to trap and remove solid particulate impurities from fluids (liquids or gases) through filter elements such as filter screens and filter cartridges, protecting downstream pumps, valves, instruments, and other equipment from contamination and wear, and ensuring stable system operation. The commonly known structure of existing filters typically includes: a housing, inlet and outlet, filter elements, and a flange connection structure, which is currently the most mainstream connection method. Flanges with bolt holes are welded or cast onto the open end of the housing (usually the upper or lower cover) and the mating housing body. When maintenance is required, operators must use tools (such as wrenches) to loosen and remove multiple circumferentially distributed connecting bolts one by one to open the housing, remove the filter elements for cleaning or replacement, and then align the flanges, reinstall, and tighten all bolts to restore the seal.

[0003] Although flange connections offer reliable sealing and high pressure resistance, their structure itself presents several significant drawbacks in practical use, such as inconvenient assembly and disassembly, and low maintenance efficiency. Tightening and loosening multiple bolts is a laborious and time-consuming task, especially when bolts are jammed due to rust or media corrosion, making disassembly extremely difficult and significantly increasing maintenance time and labor intensity. Furthermore, they require dedicated operating space: the circumferential distribution of bolts necessitates sufficient space around the filter for tools like wrenches to rotate. In confined equipment layouts, maintenance is difficult, and rapid emergency switching is challenging. Traditional bolted connections cannot meet the demands for rapid response. Therefore, a quick-install filter is urgently needed to address these issues. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a quick-install filter to solve the problems mentioned in the background technology. This utility model adopts a longitudinal positioning and lateral precision gear transmission clamping structure, which can realize the quick installation and removal of the filter itself.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A quick-install filter includes an upper filter part, a lower filter part, and a precision gear transmission box. A connecting upper plate is installed at the lower end of the upper filter part, and a connecting lower plate is installed at the upper end of the lower filter part. The connecting lower plate is fitted to the connecting upper plate. The upper filter part, the connecting upper plate, and the connecting lower plate are internally connected to the lower filter part. Rectangular slots are provided on the front, rear, left, and right sides of the connecting lower plate and the connecting upper plate. Two precision gear transmission boxes are provided, and each of the two precision gear transmission boxes has a gear transmission box installed in the middle of its upper end. The anti-slip knobs are equipped with first precision bevel gears at both ends of their shafts. Embedded bearings are installed at both the front and rear ends of the two precision gear transmission boxes. Two bidirectional screws are installed through the inner rings of the embedded bearings. A second precision bevel gear is installed in the middle of the outside of each of the two bidirectional screws. The two second precision bevel gears mesh with the two first precision bevel gears respectively. Metal moving plates are threaded onto the front and rear ends of the two bidirectional screws. Rectangular blocks are fixed to the inner sides of the multiple metal moving plates. A strong magnet is glued to the other end of each of the multiple rectangular blocks.

[0006] Furthermore, guide shafts are longitudinally installed around the upper perimeter of the lower connecting plate, and guide grooves are longitudinally formed around the upper perimeter of the upper connecting plate.

[0007] Furthermore, the multiple guide shafts are respectively damped as they pass through multiple guide grooves.

[0008] Furthermore, a sealing rubber sheet is provided at the gap between the upper connecting plate and the lower connecting plate.

[0009] Furthermore, the multiple rectangular blocks are respectively inserted into the multiple rectangular slots, and the multiple strong magnets are respectively attracted and fixed to the front and rear ends of the connecting lower plate and the connecting upper plate by magnetic attraction. The multiple metal movable plates respectively abut against the front and rear ends and left and right sides of the connecting lower plate and the connecting upper plate.

[0010] Furthermore, anti-detachment plates are installed at both the front and rear ends of the two bidirectional screws, and the threads at the front and rear ends of the two bidirectional screws rotate in opposite directions.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a quick-install filter. Because it adds a connecting upper plate, a connecting lower plate, a sealing rubber sheet, a guide shaft, a precision gear transmission box, a metal moving plate, a rectangular locking block, an anti-detachment plate, a bidirectional screw, an anti-slip knob, a first precision bevel gear, a second precision bevel gear, and a powerful magnet, the structure is reasonable. It adopts a longitudinal positioning and a lateral precision gear transmission locking structure, which enables the quick installation and removal of the filter itself. Moreover, the knob-type operation does not require a large dedicated operating space and can be installed and removed in equipment layouts with limited space, making it highly practical.

Detailed Implementation

[0018] 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.

[0019] Please see Figures 1-4This utility model provides a technical solution: a quick-install filter, including an upper filter 1, a lower filter 2, and a precision gear transmission box 9. A connecting upper plate 3 is installed at the lower end of the upper filter 1, and a connecting lower plate 4 is installed at the upper end of the lower filter 2. The connecting lower plate 4 fits snugly against the connecting upper plate 3. The upper filter 1, connecting upper plate 3, and connecting lower plate 4 are internally connected to the lower filter 2. Rectangular slots 8 are provided on the front, rear, left, and right sides of both the connecting lower plate 4 and the connecting upper plate 3. Two precision gear transmission boxes 9 are provided. An anti-slip knob 14 is installed in the middle of the upper end of each of the two precision gear transmission boxes 9. A first precision bevel gear 15 is installed on the shaft end of each of the two anti-slip knobs 14. Embedded bearings 17 are installed at both the front and rear ends of the filter. Two bidirectional screws 13 are installed through the inner rings of the multiple embedded bearings 17. A second precision bevel gear 16 is installed in the middle of the outer side of each of the two bidirectional screws 13. The two second precision bevel gears 16 mesh with two first precision bevel gears 15 respectively. Metal moving plates 10 are threaded onto the front and rear ends of the two bidirectional screws 13. Rectangular blocks 11 are fixed on the inner side of the multiple metal moving plates 10. A strong magnet 18 is glued to the other end of each of the multiple rectangular blocks 11. This design solves the problems of inconvenient disassembly and assembly, low maintenance efficiency, need for dedicated operating space, and the inability of traditional bolt connection to meet the needs of rapid response in the original filter.

[0020] As the first embodiment of this utility model: guide shafts 6 are longitudinally installed around the upper circumference of the lower connecting plate 4, and guide grooves 7 are longitudinally formed around the upper circumference of the upper connecting plate 3. Through the added guide shafts 6 and guide grooves 7, precise longitudinal positioning is achieved during the initial assembly stage, ensuring that the upper connecting plate 3 and the lower connecting plate 4 can be quickly and accurately aligned. This prevents poor sealing or installation difficulties due to misalignment, laying the foundation for subsequent locking operations. Multiple guide shafts 6 pass through multiple guide grooves 7 with damping. Through the added damping, the guide shafts 6 maintain a certain friction after being inserted into the guide grooves 7. Before the locking mechanism is activated, the relative positions of the upper connecting plate 3 and the lower connecting plate 4 can be temporarily maintained, facilitating single-person operation and preventing components from dislodging due to gravity or slight shaking.

[0021] A sealing rubber sheet 5 is provided at the joint between the upper plate 3 and the lower plate 4. The added sealing rubber sheet 5 serves as the main sealing element. When the upper plate 3 and the lower plate 4 are pressed together, it undergoes elastic deformation, effectively filling the microscopic unevenness between the mating surfaces and ensuring that the internal fluid will not leak from the joint gap when the filter is working under high pressure.

[0022] Multiple rectangular locking blocks 11 are respectively inserted into multiple rectangular locking slots 8. Multiple strong magnetic pieces 18 are magnetically attracted and fixed to the front and rear ends of the connecting lower plate 4 and the connecting upper plate 3. Multiple metal movable plates 10 abut against the front, rear, left and right sides of the connecting lower plate 4 and the connecting upper plate 3. Through the cooperation of the added rectangular locking blocks 11 and the rectangular locking slots 8, the horizontal linear motion generated by the gear transmission is converted into a rigid locking force in the front-back direction of the connecting part of the connecting lower plate 4 and the connecting upper plate 3, forming a solid mechanical connection. When the rectangular locking blocks 11 are fully inserted, the strong magnetic pieces 18 provide additional magnetic attraction and retention force, which can not only prevent the locking mechanism from loosening due to vibration during equipment operation, but also provide an initial separation force when unlocking, indicating to the operator that the locking state has been released.

[0023] Both front and rear ends of the two bidirectional screws 13 are equipped with anti-detachment plates 12. The threads of the two bidirectional screws 13 rotate in opposite directions. The anti-detachment plates 12 effectively limit the extreme travel of the metal moving plate 10 on the bidirectional screws 13, preventing it from falling off the screws due to excessive movement, thus improving the reliability and service life of the mechanism. The design of the opposite thread directions at both ends of the bidirectional screws 13 allows the metal moving plates 10 at both ends to move synchronously towards or away from each other when the screws rotate, thereby enabling the four rectangular locking blocks 11 to extend and lock or retract and unlock.

[0024] As a second embodiment of this utility model: First, lower the upper part 1 of the filter, aligning the guide groove 7 on the connecting upper plate 3 at its bottom with the guide shaft 6 on the connecting lower plate 4, and slowly lower it until the two are in contact, initially compressing the sealing rubber sheet 5. Then, the operator simultaneously (or sequentially) rotates the anti-slip knobs 14 on the two precision gear transmission boxes 9. The knobs drive the first precision bevel gear 15 to rotate, and through the meshing of the bevel gear pair, the vertical rotational motion is converted into the horizontal rotation of the bidirectional screw 13. Since the threads at both ends of the bidirectional screw 13 rotate in opposite directions, the metal moving plates 10 at both ends move synchronously towards the center under the thread drive, causing the rectangular locking block 11 to be horizontally inserted into the rectangular locking groove 8 of the connecting upper plate 3 and the connecting lower plate 4. When the rectangular locking block 11 is fully in place, the strong magnetic piece 18 at its end attracts the metal connecting plate, producing a slight "click" sound or tactile sensation, indicating that the locking is complete. At this point, the upper connecting plate 3 and the lower connecting plate 4 are securely locked together. When the filter element needs to be replaced or the equipment needs to be repaired, the operation procedure is the reverse of the locking procedure. The operator only needs to rotate the two anti-slip knobs 14 in the opposite direction, and the bidirectional screw 13 will rotate in the opposite direction, driving the metal moving plates 10 at both ends to move backward, causing the rectangular locking block 11 to smoothly exit from the rectangular locking slot 8. When the magnetic attraction disappears, it indicates that the locking has been released. At this time, with the assistance of the guide mechanism, the upper part 1 of the filter can be lifted directly upward to complete the separation. The whole process does not require any tools and can be completed by simply rotating the knobs by hand, which takes very little time.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
