Description

Technical Field

[0001] The utility model relates to the technical field of cone filter elements, in particular to a foldable cone filter element mechanism. Background Art

[0002] The filter element is a simple device for purifying the resources of the original fluid and separating the resources. Now the filter element is mainly used in the filtration industry such as oil filtration, air filtration, water filtration, etc. Its function is to filter impurities or dust, etc., so as to facilitate the circulation of equipment. The conical filter element, as the name suggests, has a cone shape and belongs to the pipeline coarse filtration series. It has a simple form and is generally installed on the pipeline to remove larger solid impurities in the fluid, so that machinery and equipment (including compressors, pumps, etc.) and instruments can work and operate normally, ensuring the safe production of equipment.

[0003] When the existing filter elements are in use, they are not only used for various filtrations in small equipment, but some filter elements are also installed in large equipment for working filtration, which requires the use of conical filter elements. Most of the existing filter elements are formed in one piece, do not have a folding function, and cannot change their shape. According to production needs, a large number of filter elements are stored, which takes up a large amount of space and is not convenient for storing and storing the filter elements. During the equipment production process, when the instrument detects that the pressure difference before and after the filter element reaches a certain value, it means that the filter is clogged and the internal filter element needs to be disassembled and cleaned. However, some of the existing filter elements are clamped by the sealing surface of the filter element and the flange gasket and fixed by bolts, which is not convenient for disassembly and assembly of the filter element. At the same time, due to the particularity of the structure of the conical filter element itself, it is easily damaged by external factors during the disassembly and assembly process, resulting in that it cannot be disassembled and assembled as conveniently and quickly as general equipment when it is maintained.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6As shown, the foldable conical filter mechanism comprises a conical filter body 1, which is a segmented design. The conical filter body 1 is composed of three connected conical shells. The internal parts of the conical filter body 1 can be folded together. A slide groove 2 is provided on the surface of the conical filter body 1. The shape of the slide groove 2 is L-shaped. The number of the slide grooves 2 is six, and the slide grooves 2 are grouped in three and are distributed in a circular array at the center of the bottom of the conical shell of the conical filter body 1 on the top of the conical filter body 1 and the surface of the two middle conical shells. The positions of the slide grooves 2 at the upper and lower positions are staggered with each other, and the slide grooves 2 are connected to the internal parts. The parts cooperate to guide the two conical shells below the conical filter element body 1, so as to facilitate the folding and contraction of the conical shells of the conical filter element body 1. Positioning mechanisms 3 are arranged on the upper and lower sides of the inner wall of the conical filter element body 1. The number of positioning mechanisms 3 is consistent with the slide groove 2, and the positions of the positioning mechanisms 3 and the slide groove 2 correspond to each other. The positioning mechanisms 3 are used in conjunction with the slide groove 2 to position the two conical shells below the conical filter element body 1, limit the folding range of the conical shells, and facilitate the folding and unfolding of the conical filter element body 1. A limiting mechanism 4 is arranged on one side extending below the slide groove 2, and the position of the limiting mechanism 4 corresponds to the positioning mechanism 3. , and the number of the limiting mechanisms 4 is consistent with that of the positioning mechanisms 3. The limiting mechanisms 4 are used to limit the components of the positioning mechanisms 3 to prevent the components of the positioning mechanisms 3 from being displaced arbitrarily during use and affecting the fixing effect of the conical shell. A baffle 5 is fixedly connected to one side of the top of the conical filter element body 1. The baffle 5 is used to limit the conical shell above the conical filter element body 1 and fix the folded conical shell inside the bottom conical shell to prevent the top and middle conical shells of the conical filter element body 1 from unfolding toward the bottom of the conical filter element body 1 when folding, thereby affecting the folding effect. The bottom of the conical filter element body 1 is movable A fixing plate 6 is connected, and the fixing plate 6 is used to install the conical filter element body 1. The fixing plate 6 can be fixed to the position where the conical filter element body 1 needs to be installed. Both sides of the top of the fixing plate 6 are provided with mounting grooves 7, and the mounting grooves 7 are used to install parts. The interior of the mounting grooves 7 is provided with mounting mechanisms 8, and the mounting mechanisms 8 are respectively located on both sides of the bottom of the conical filter element body 1. The mounting mechanisms 8 are used to limit the conical filter element body 1 when installing the conical filter element body 1, and fix the conical filter element body 1 to the place where the equipment needs to filter, so as to facilitate the disassembly and assembly of the conical filter element body 1, and to use it conveniently, thereby improving the efficiency of installation.

[0024] The positioning mechanism 3 includes a positioning groove 31 opened on the upper part of the conical shell of the conical filter element body 1. The number of the positioning grooves 31 is six and three are in a group. The positioning grooves 31 are distributed in a circular array at the center of the bottom of the conical filter element body 1 and above the inner walls of the conical shell in the middle and bottom of the conical filter element body 1. A squeezing spring 32 is fixedly connected to one side of the inner wall of the positioning groove 31. The squeezing spring 32 is slidably connected to the inner wall of the positioning groove 31. A positioning block 33 is fixedly connected to one end of the squeezing spring 32. The positioning block 33 is slidably connected to the inner wall of the slide groove 2. The positioning block 33 is slidably connected to the inner wall of the positioning groove 31. In the process of folding the conical filter element body 1, under the action of the squeezing spring 32, the positioning block 33 always slides inside the slide groove 2, and the moving range of the positioning block 33 is limited by the slide groove 2, so as to position part of the conical shell of the conical filter element body 1, so as to facilitate the folding and unfolding of the conical filter element body 1.

[0025] The limiting mechanism 4 includes a limiting groove 41 connected to one side of the horizontal extension of the slide groove 2. The number of the limiting grooves 41 is consistent with the slide groove 2, and the positioning block 33 is movably connected to the inner wall of the limiting groove 41. The top of the inner wall of the limiting groove 41 is fixedly connected with a telescopic spring 42, and the bottom of the telescopic spring 42 is fixedly connected with a limiting rod 43. The limiting rod 43 is movably connected to the surface of the top of the positioning block 33. One side of the bottom of the limiting rod 43 is inclined. When the conical shell of the conical filter element body 1 is unfolded, the positioning block 33 is slid to one side of the bottom of the inner cavity of the slide groove 2, and then one side of the conical shell is rotated to move the positioning block 33. When the conical filter element 1 is in use, the conical shell of the conical filter element 1 is prevented from rotating due to external force and affecting the unfolding effect, so as to facilitate the unfolding and shaping of the conical filter element 1. Similarly, the conical shell on one side is stretched and rotated in the opposite direction to release the limit on the positioning block 33 and fold the conical filter element 1. The operation is continuous, simple and portable.

[0026] The mounting mechanism 8 includes a limit block 81 fixed inside the mounting groove 7, the top of the limit block 81 and the top of the fixing plate 6 are on the same horizontal line, one side of the bottom of the limit block 81 is extended, both sides of the bottom flat plate of the conical filter element body 1 are rotatably connected with a rotating rod 82, a rotating lever is fixed on the top of the rotating rod 82, and both sides of the bottom of the surface of the rotating rod 82 are fixedly connected with a fixed block 83. When the fixed block 83 is embedded in the mounting groove 7, the inner surface of the limit block 81 is slidably connected to the surface of the rotating rod 82, and the limit block 81 is used to block the fixed block 83. The fixed block 83 is movably connected to the inner wall of the mounting groove 7, and the fixed block 83 is movably connected to the surface of the limit block 81. Then, the fixing block 83 is consistent with the limiting block 81 in shape, and their positions are staggered. When installing the conical filter element body 1, the fixing blocks 83 on both sides are aligned with the vacant places inside the limiting block 81 and the fixing blocks 83 are embedded in the installation groove 7. Then, the two rotating rods 82 are rotated in sequence to make the fixing blocks 83 overlap with the bottom of the limiting block 81 to limit the conical filter element body 1, so as to install and fix the conical filter element body 1. Similarly, the rotating rod 82 is rotated in the opposite direction to drive the fixing block 83 to rotate to the position staggered with the limiting block 81. Then, the conical filter element body 1 can be removed by moving the conical filter element body 1 upward. The operation is simple and convenient, and it is easy to disassemble and assemble the conical filter element body 1.

[0027] Working principle: First, when the conical filter element body 1 needs to be folded, the conical shell on the top of the conical filter element body 1 is slightly pressed downwards, and the positioning block 33 is moved inside the limiting groove 41 to be parallel to one side of the inner cavity of the slide groove 2 through the setting of the telescopic spring 42, and then the top conical shell is rotated to one side, so that the positioning block 33 moves to one side along the inner wall of the slide groove 2, and then the conical shell is pressed downwards, and the conical shell on the top of the conical filter element body 1 can be folded inside the middle conical shell, and the above operation can be repeated to fold the middle conical shell and the other conical shell inside it into the bottom conical shell, so as to fold the conical filter element body 1, and similarly, the reverse directions are repeated in sequence. The operation can unfold the conical filter element body 1. When installing the conical filter element body 1, the fixing blocks 83 on both sides of the bottom of the conical filter element body 1 are aligned with the vacant positions inside the limit blocks 81 and the fixing blocks 83 are embedded in the inside of the installation groove 7. Then, the two rotating rods 82 are rotated in sequence to make the fixing blocks 83 coincide with the bottoms of the limit blocks 81 to limit the conical filter element body 1. In this way, the conical filter element body 1 can be installed and fixed. Similarly, when the conical filter element body 1 needs to be removed, the rotating rod 82 is rotated in the opposite direction to control the fixing blocks 83 to rotate to intersect with the position of the limit blocks 81, and then the conical filter element body 1 is moved upward to remove the conical filter element body 1.
