Description

Technical Field

[0001] This utility model relates to the field of meltblown filter element installation technology, and in particular to an adjustable clamping and fixing device for meltblown filter elements. Background Technology

[0002] Meltblown filter cartridges are ultra-fine fiber filter materials made through a meltblown process. They are made primarily from thermoplastic resins such as polypropylene (PP) and form a three-dimensional network structure through processes such as high-temperature melting, high-pressure spraying, and fiber stretching. They have high porosity, large specific surface area, and gradient filtration characteristics, and are widely used in the precision filtration of liquids and gases.

[0003] Meltblown filter cartridges typically require a fixing device to secure them. Conventional fixing devices for installing meltblown filter cartridges involve passing them through a base plate and cover plate. When used in gas filtration devices, different thicknesses of meltblown filter cartridges are needed depending on the size of the equipment. Multiple meltblown filter cartridges are usually combined and need to maintain a certain distance. However, existing fixing devices cannot be adjusted, resulting in insufficient distance between multiple meltblown filter cartridges when using thicker cartridges. This affects the filtration efficiency and service life of the meltblown filter cartridges. Utility Model Content

[0004] In view of this, the present invention provides an adjustable clamping and fixing device for meltblown filter elements. The main technical problem to be solved is that the existing fixing device cannot be adjusted, which leads to the spacing between multiple meltblown filter elements of different thicknesses being too small, thereby affecting the filtration efficiency and service life of the meltblown filter elements.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable clamping and fixing device for meltblown filter elements, comprising a base plate and a cover plate, both of which are cross-shaped structures. Four sliders are slidably connected inside the base plate. Ears are fixedly connected to the outer walls of the sliders. A housing is fixedly connected to the outer wall of the base plate. Two locking rods are slidably connected inside the housing. The two locking rods are symmetrically arranged inside the housing. The locking rods are slidably connected to the base plate and the sliders. Springs are installed inside the two locking rods. Four sliders are slidably connected inside the cover plate. Ears are fixedly connected to the outer walls of the sliders. A housing is fixedly connected to the outer wall of the cover plate. Two locking rods are slidably connected inside the housing. The two locking rods are symmetrically arranged inside the housing. The locking rods are slidably connected to the cover plate and the sliders. Springs are installed inside the two locking rods.

[0006] By adopting the above technical solution, pressing lever one and lever two respectively causes them to slide and release their restriction on slider one and slider two. Then, by moving ear seat one and ear seat two, slider one and slider two are moved outwards respectively. When the outward movement distance of slider one and slider two is adjusted to be the same, lever one and lever two are released, causing lever one and lever two to engage with corresponding positions inside slider one and slider two respectively, thus limiting and fixing slider one and slider two. This achieves the position adjustment effect of ear seat one and ear seat two, which facilitates the installation of meltblown filter elements of different thicknesses. It also ensures that the distance between multiple meltblown filter elements is always maintained when it is necessary to replace meltblown filter elements of different thicknesses, preventing any impact on the filtration efficiency and service life of the meltblown filter elements.

[0007] As a further description of the above technical solution: the two ends of the first spring are respectively fixedly connected to the inside of the two first clamps, and the two ends of the second spring are respectively fixedly connected to the inside of the two second clamps.

[0008] By adopting the above technical solution, spring one supports two locking rods one, and spring two supports two locking rods two.

[0009] As a further description of the above technical solution: a threaded rod is fixedly connected to the upper surface of the ear seat one, the threaded rod penetrates the interior of the ear seat two, and a nut is threadedly connected to the outer wall of the threaded rod, the nut being positioned above the ear seat two.

[0010] By adopting the above technical solution, the meltblown filter element is first inserted through the threaded rod, and then the second lug on the outer wall of the cover plate is aligned with the threaded rod and inserted through it, so that the upper end of the threaded rod is placed above the second lug. Then, the nut is threaded to the upper end of the outer wall of the threaded rod, and the lower surface of the nut is made to fit with the upper surface of the second lug. When it is necessary to adjust the tightness of the meltblown filter element, the cover plate is pressed down, and then the four nuts are rotated respectively so that their lower surfaces fit with the upper surface of the second lug, thereby pressing and limiting the meltblown filter element.

[0011] As a further description of the above technical solution: the ear base is provided with an internal support assembly, the internal support assembly including a rotating plate, the rotating plate being disposed inside the ear base.

[0012] By adopting the above technical solution, the inner wall of the meltblown filter element is supported by adjusting the inner support assembly through the rotation of the rotating plate.

[0013] As a further description of the above technical solution: a lead screw is fixedly connected to the upper surface of the rotating plate, and the lead screw is threadedly connected to the inside of the lug.

[0014] By adopting the above technical solution, rotating the rotating plate drives the lead screw to rotate, enabling the lead screw to be adjusted in height.

[0015] As a further description of the above technical solution: a cone block is movably connected to the outer wall of the lead screw, and the cone block slides longitudinally inside the threaded rod.

[0016] By adopting the above technical solution, the lead screw is limited to rotating inside the cone block, and the cone block is driven to rise and fall during the rotation and lifting of the lead screw.

[0017] As a further description of the above technical solution: the inner two sides of the threaded rod are laterally slidably connected with connecting blocks, and the outer wall of the connecting blocks is in contact with the outer wall of the cone block.

[0018] By adopting the above technical solution, the connecting block is limited to slide laterally inside the threaded rod. During the lifting and lowering of the cone block, the connecting block is squeezed, thereby driving the connecting block to slide laterally.

[0019] As a further description of the above technical solution: a support plate is fixedly connected to the outer wall of the connecting block on the side away from the cone block, and a melt-blown filter element is sleeved on the outer wall of the support plate.

[0020] By adopting the above technical solution, the lateral sliding of the connecting block drives the support plate to move, thereby achieving the effect of supporting the inner wall of the meltblown filter element.

[0021] By employing the above technical solution, the adjustable clamping and fixing device for meltblown filter cartridges of this utility model has at least the following beneficial effects:

[0022] 1. Compared with existing technologies, this adjustable clamping and fixing device for meltblown filter elements, through the arrangement of slider one, ear seat one, sleeve one, clamp rod one, spring one, slider two, ear seat two, sleeve two, clamp rod two, and spring two, allows for the adjustment of the positions of ear seats one and two when different thicknesses of meltblown filter elements need to be installed. Clamp rod one and clamp rod two are pressed to slide out of the interior of slider one and slider two respectively. Then, ear seats one and two are moved outwards, causing slider one and slider two to move outwards until their movement distances are equal. Then, clamp rod one and clamp rod two are released, and spring one and spring two cause clamp rod one and clamp rod two to reset and engage with the interior of slider one and slider two, thus limiting and fixing them. This allows the position of ear seats one and two to be adjusted according to the thickness of the meltblown filter element, ensuring that thicker meltblown filter elements maintain a certain distance during installation and use, preventing any impact on the filtration efficiency and service life of the meltblown filter element.

[0023] 2. Compared with the prior art, this adjustable clamping and fixing device for meltblown filter elements uses a threaded rod, rotating plate, lead screw, cone block, connecting block and support plate to place the meltblown filter element through the threaded rod and outside the two support plates. Rotating the rotating plate causes the lead screw to move down, causing the cone block to move down. During the downward movement of the cone block, the two connecting blocks are pushed outward at the same time, which in turn causes the support plate to move outward and fit against the inner wall of the meltblown filter element, thus supporting the inner wall of the meltblown filter element and preventing the meltblown filter element from shaking during use.

Then, the ear seat 202 on the outer wall of the cover plate 2 is aligned with the threaded rod 3 and pressed down, causing its lower surface to fit against the upper surface of the meltblown filter element. The upper surface of the ear seat 102 and the lower surface of the meltblown filter element are then aligned. The surfaces are fitted together, and the central hole of the meltblown filter element is sealed by ear seat 102 and ear seat 202. Then, the nut 301 is threaded onto the outer wall of the threaded rod 3, causing its lower surface to fit against the upper surface of ear seat 202, pressing ear seat 202 tightly above the meltblown filter element. When it is necessary to adjust the tightness of the meltblown filter element, the cover plate 2 can be pressed down directly, causing ear seat 202 to move down and squeeze the meltblown filter element. Then, the nut 301 is rotated to... The lower part of the ear seat 202 is attached to the upper surface, thereby completing the adjustment of the pressure of the meltblown filter element.

[0037] Working principle: When installing meltblown filter elements, adjust the distance between the four lugs 102 and 202 according to the thickness of the meltblown filter element to ensure that the meltblown filter elements maintain a certain distance to prevent affecting the filtration effect and service life of the meltblown filter elements. During the adjustment process, first press the two locking rods 104 on the outer wall of the housing 103 to make the two locking rods 104 slide in the center and slide out of the groove inside the slider 101. Then move the lugs 102 outward to drive the slider 101 outward. Adjust the moving distance of the slider 101 according to the thickness of the meltblown filter element. After the adjustment is completed, release the locking rods 104, and the spring 105 will drive the locking rods 102 outward. 04. Reset the position, causing one end of the locking lever 104 to slide and engage in the corresponding slot inside the moved slider 101. Then, adjust the distance between the ear seat 202 and the slider 201. Press the locking lever 204 on both sides of the outer wall of the housing 203, causing the locking lever 204 to slide in the center and have one end slide out of the slot inside the slider 201. Then, move the ear seat 202 outward, causing the slider 201 to move, so that the distance moved by the slider 201 is equal to the distance moved by the slider 101. Then, release the locking lever 204, and the spring 205 will reset the locking lever 204, causing one end to slide and engage in the corresponding slot inside the moved slider 201. After adjustment, the meltblown filter element is inserted through the threaded rod 3, so that its lower surface is in contact with the upper surface of the lug 102 and placed outside the support plate 405. Rotating the rotating plate 401 causes the screw 402 to rotate, causing the cone 403 to move downward. The cone 403 moves downward and presses the connecting block 404 to both sides. The connecting block 404 slides to both sides and drives the support plate 405 to move, causing the outer wall of the support plate 405 to be in contact with the inner wall of the meltblown filter element, thus supporting the inner wall of the meltblown filter element. Then, the lug 202 on the outer wall of the cover plate 2 is aligned with the threaded rod 3 and inserted. The cover plate 2 is moved down, causing the lug 202 to move down. After the lug 202 moves down, its lower surface is in contact with the upper surface of the meltblown filter element. Using the pressure of the cover plate 2, the ear seat 202 moves downward to press the meltblown filter element together with the base plate 1 and the ear seat 102. Then, the nut 301 is threaded onto the upper end of the threaded rod 3 and its lower surface is made to fit against the upper surface of the ear seat 202 to limit the ear seat 202 and the cover plate 2. When it is necessary to adjust the pressure on the meltblown filter element, rotate the nut 301 to move it upward away from the ear seat 202. Adjust the height of the cover plate 2 and the ear seat 202 to change the pressure on the meltblown filter element. Then rotate the nut 301 to make its lower surface fit against the upper surface of the ear seat 202. After completing all the installation and adjustment steps, place the whole device inside the gas filtration device for installation.
