Description

Technical Field

[0001] This utility model relates to the field of air purification equipment technology, specifically to a leak-proof filter sealing installation structure. Background Technology

[0002] In industries such as electronics, semiconductors, pharmaceuticals, and biosafety, the cleanliness of cleanrooms is a core guarantee of product quality and safety. Cleanrooms place extremely high demands on the reliability of seals at filter interfaces. Currently, the industry commonly uses a liquid-sealable system for these filters. This system involves pre-fabricating annular liquid grooves on the filter's frame and filling them with a special sealant. Corresponding annular cutting edges are provided on the mounting frame; during installation, these cutting edges are inserted into the sealant, and the sealant's encapsulation ensures a tight seal.

[0003] For filters that need to be horizontally mounted in vertical ducts, installers typically need to be at a height (such as on scaffolding or ladders) to support the filter and insert it into the duct, ensuring the cutting edge doesn't shift during insertion into the liquid tank. However, because the installation position is above head height, operators cannot see the filter and must rely on feel. Furthermore, the installation process requires continuous force, demanding a high level of coordination and physical strength from the operator. Improper coordination necessitates reversing the operation and realigning, making the installation time-consuming.

[0004] To address the aforementioned issues, existing technologies utilize drive structures such as screws at the air duct inlets to assist in lifting the filter. While proper operation can ensure no deviation during the lifting process, repeated adjustments are still required during the alignment of the cutting edge and the liquid tank. This results in poor repeatability of the installation results. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a leak-proof filter sealing installation structure.

[0006] The technical solution of this utility model is: A leak-proof filter sealing installation structure, comprising: The filter, wherein the filter element sleeve is provided with a liquid seal structure on the side; The air duct has a sealing skirt at its opening, and the bottom surface of the sealing skirt has a blade and a locking structure for fixing the filter. A guide structure is provided between the outer side of the filter sleeve and the inner side of the air duct; The guiding structure includes several upper guide blocks arranged circumferentially on the outside of the filter sleeve and several limiting tubes correspondingly arranged on the inside of the air duct. Each pair of limiting tubes forms a group and slides together with one of the upper guide blocks to restrict its movement direction.

[0007] Preferably, the upper guide block has a hexagonal cross-section, which is formed by cutting off two apex corners of a rectangle.

[0008] Preferably, the limiting tube is provided with an insert block through an elastic element, the insert block penetrates the side wall of the limiting tube and extends upward in the direction of the guide block.

[0009] Preferably, the insert has a right-angled trapezoidal cross-section, with the inclined surface facing downwards and towards the outside of the limiting tube.

[0010] Preferably, the insert extends beyond the outermost end of the side wall of the limiting tube, and in the horizontal direction does not exceed the vertical plane where the intersection of the inclined surface and the top surface of the upper guide block is located.

[0011] Preferably, a lower slider is provided directly below the upper guide block via a sliding guide structure. The lower slider has the same shape as the upper guide block but is installed in the opposite direction. When the filter is installed in place, the lower slider is located just above the insert block.

[0012] Preferably, the sliding guide structure includes a slide rod, the upper end of which is fixedly connected to the upper guide block, and the lower end of which passes through the lower slide block and is provided with a lower stop block.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes the sliding engagement of the upper guide block and paired limiting tubes to ensure precise insertion of the duct blade into the filter's liquid seal structure, achieving a reliable seal. During installation, an automatic pop-out block prevents the upper guide block from retracting, thus preventing the filter from accidentally falling and improving installation safety. The filter will not completely retract when adjusting its position or during breaks, reducing alignment time and enhancing installation convenience. During disassembly, the lower slider ensures smooth disengagement. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: Please see Figure 1-6 The present invention will describe the above technical solution in detail through the following embodiments: A leak-proof filter sealing installation structure, comprising: Filter 1, the filter element sleeve 101 of filter 1 is provided with a liquid seal structure on the side; The filter element 104 is bonded and fixed inside the filter sleeve 101.

[0018] The liquid seal structure includes a liquid seal groove 102 located at the bottom of the side of the filter element sleeve 101, and liquid seal adhesive 103 is poured into the liquid seal groove 102.

[0019] The air duct 6 has a sealing skirt 7 at its opening, and the bottom surface of the sealing skirt 7 has a blade 8 and a locking structure for fixing the filter 1.

[0020] The locking structure includes a rotating shaft 12 and a locking plate 13 rotatably connected to the rotating shaft 12.

[0021] When filter 1 is installed in place, rotating locking plate 13 to the direction of filter 1 can prevent filter 1 from falling.

[0022] A guide structure is provided between the outer side of the filter sleeve 101 and the inner side of the air duct 6.

[0023] The guiding structure includes several upper guide blocks 2 arranged circumferentially on the outside of the filter sleeve 101 and several limiting tubes 9 correspondingly arranged on the inside of the air duct 6. Each pair of limiting tubes 9 forms a group and slides together with an upper guide block 2 to limit its movement direction.

[0024] The limiting tube 9 is a square metal tube and is welded to the air duct 6. The guide block 2 can be a metal block or a nylon block and is fixedly connected to the filter sleeve 101 by welding or screws.

[0025] The filter sleeve 101 has two guide blocks 2 welded on each side, and the air duct 6 has four limiting tubes 9 welded on each side.

[0026] The guide block 2 is restricted to slide left and right by the limiting tube 9, so as to ensure that the filter sleeve 101 will not deviate when it is inserted.

[0027] The upper guide block 2 has a hexagonal cross-section, which is formed by cutting off the two vertices of a rectangle.

[0028] The two inclined surfaces of the upper guide block 2 can be easily inserted between the two limiting tubes 9, facilitating centering.

[0029] An insert block 10 is provided inside the limiting tube 9 via an elastic element 11. The insert block 10 penetrates the side wall of the limiting tube 9 and extends upward towards the guide block 2.

[0030] The elastic element 11 can be a metal spring sheet, with the protruding part facing the guide block 2, so that the insert block 10 always extends out of the limiting tube 9 when it is not subjected to external force.

[0031] The insert 10 has a right-angled trapezoidal cross-section, with the inclined surface facing down and towards the outside of the limiting tube 9.

[0032] The insert 10 extends out of the outermost end of the side wall of the limiting tube 9, and does not exceed the vertical plane where the intersection of the inclined surface and the top surface of the upper guide block 2 is located in the horizontal direction.

[0033] During the insertion of filter 1, the inclined surface of the upper guide block 2 will abut against the inclined surface of the insertion block 10 first, squeezing the insertion block 10 to both sides. After the upper guide block 2 passes smoothly, the insertion block 10 will pop out, restricting the upper guide block 2 from exiting, thereby preventing filter 1 from falling.

[0034] A sliding block 4 is provided directly below the upper guide block 2 via a sliding guide structure. The lower block 4 has the same shape as the upper guide block 2 but is installed in the opposite direction. When the filter 1 is installed in place, the lower block 4 is just above the insert block 10.

[0035] During the insertion of filter 1, once the upper guide block 2 has passed the insertion block 10, continuing to push filter 1 upward will cause the two right angles of the lower slider 4 to press against the inclined surface of the insertion block 10, pushing the insertion block 10 back into the limiting tube 9. After the lower slider 4 has passed smoothly, the insertion block 10 will pop out. Once fully in place, rotate the locking plate 13 to support the end face of filter 1, completing the installation of filter 1.

[0036] The sliding guide structure includes a slide rod 3, the upper end of which is fixedly connected to the upper guide block 2, and the lower end of the slide rod 3 passes through the lower slide block 4 and is provided with a lower stop block 5.

[0037] During disassembly, first release the locking plate 13 from the filter 1. The filter 1 descends, and the lower slider 4 remains stationary due to the obstruction of the insertion block 10. At this time, the upper guide block 2 will move towards the lower slider 4.

[0038] When the upper guide block 2 abuts against the lower slider 4, the filter 1 continues to move downward, and the inclined surface of the lower slider 4 pushes the insert block 10 to both sides.

[0039] Since the insert 10 is a right trapezoid, its end face can pass smoothly through the joint between the upper guide block 2 and the lower slider 4 until the insert 10 is in the inclined position of the upper guide block 2 before it can extend.

[0040] Working principle: Installation process: Align filter 1 with duct 6 and insert upper guide block 2 between two limiting tubes 9.

[0041] During the insertion of filter 1, the inclined surface of the upper guide block 2 will abut against the inclined surface of the insertion block 10 first, squeezing the insertion block 10 to both sides. After the upper guide block 2 passes smoothly, the insertion block 10 will pop out, restricting the upper guide block 2 from exiting, thereby preventing filter 1 from falling.

[0042] Once the upper guide block 2 has passed the insertion block 10, continue pushing the filter 1 upwards. This will cause the two right angles of the lower slider 4 to press against the inclined surface of the insertion block 10, pushing the insertion block 10 back into the limiting tube 9. After the lower slider 4 has passed smoothly, the insertion block 10 will pop out. Once fully in place, rotate the locking plate 13 to support the end face of the filter 1, completing the installation of the filter 1.

[0043] Disassembly process: First, release the locking plate 13 from the filter 1. The filter 1 descends, and the lower slider 4 remains stationary due to the obstruction of the insertion block 10. At this time, the upper guide block 2 will move in the direction of the lower slider 4.

[0044] When the upper guide block 2 abuts against the lower slider 4, the filter 1 continues to move downward, and the inclined surface of the lower slider 4 pushes the insert block 10 to both sides.

[0045] Since the insert 10 is a right trapezoid, its end face can pass smoothly through the joint between the upper guide block 2 and the lower slider 4 until the insert 10 is in the inclined position of the upper guide block 2 before it can extend.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
