Detailed Description

The drawings are for illustrative purposes only and are not to be construed as limiting the patent; for the purpose of better illustrating the embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted" and "connected" are to be interpreted broadly, e.g., as being either fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, so to speak, as communicating between the two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art. The technical solution of the present invention is further described below with reference to the accompanying drawings and examples.

As shown in fig. 1-3, the novel filter screen structure of the present invention includes frames 1, the number of the frames 1 is at least two, and the sizes of the frames 1 are the same, a plurality of the frames 1 are stacked and sequentially detachably connected, a filter screen 2 is sandwiched between every two frames 1, and the peripheral edges of the filter screen 2 are located at the frame of the frame 1; the plurality of frames 1 are provided at outer edges thereof with sealing layers 3, and the outer surfaces of the sealing layers 3 are further coated with an adhesive material. The utility model is convenient to assemble and disassemble, is used for being arranged on the positions of an air pipeline and the like of a filter, can be quickly bonded and combined with a device in the filter pipeline, forms effective seal, is convenient to replace and clean, is more beneficial to air filtration, and saves the maintenance cost.

This structure utilizes frame 1 can dismantle the combination and form the fixed skeleton of filter screen 2, and through the combination of a plurality of frames 1, can set up simultaneously that multi-disc filter screen 2 strengthens the filter effect, also can select to use according to actual conditions, but needs two frames 1 at least just can press from both sides filter screen 2 in the middle of, and utilizes frame 1's frame to press from both sides filter screen 2 tightly, can avoid filter screen 2 crooked etc. to cause the space and reduce the filter effect. When the sealing layer 3 is installed, the sealing layer 3 is generally made of rubber sealing strips and other materials, has certain elasticity, can make up clearance errors generated when the frame 1 is installed on a pipeline, a filtering device and other positions, and meanwhile, the sealing layer 3 is further bonded and fixed by using bonding materials, so that the undesirable situations of air leakage and the like at the position of the frame 1 are avoided. The bonding material can adopt one or more of AB glue, ultrasonic bonding agent, foaming glue and bonding resin. The AB glue is a bi-component adhesive, one liquid is the original glue, the other liquid is a hardening agent, and the two liquids are mixed and hardened to realize a relatively sealed bonding material. Ultrasonic bonding is a swift, clean, effectual assembly process for assembly processing thermoplastic plastic accessory, and ultrasonic bonding not only has the connection assembly function but also has dampproofing, waterproof sealed effect. The foaming glue is polyurethane elastic sealing foaming material solidified by moisture, and is mainly used for filling, sealing and bonding the side seams, member expansion joints and holes of building doors and windows. There are four general classes of adhesive resins that are commonly used: rosin resin, terpene resin, phenolic resin and petroleum resin are also applied to the adhesion among materials in the rubber and plastic field.

Example 1

In this embodiment, as shown in fig. 1 and 2, the filter screen structure is assembled by stacking a plurality of frames 1 and forming a raised mounting portion 11 on the outer side of the peripheral frame, and the inner side of the sealing layer 3 is fitted to the mounting portion 11. Frame 1 quantity optional two or three, after stacking the combination, its frame outside department forms bellied installation department 11, this installation department 11 overall shape is upper portion plane middle part indent, let the inboard groove of looks adaptation of sealing layer 3 overlap on this installation department 11 to further stabilize the combination of stacking between a plurality of frames 1, let sealing layer 3 parcel form the location in the frame 1 outside simultaneously, be convenient for when installing the filter screen structure, sealing layer 3 utilizes the bonding material on it to bond with filter equipment, and improve the leakproofness of sealing layer 3. In addition, for further fixing the sealing layer 3, the sealing layer 3 can be designed to extend to the inner side of the frame 1 and be buckled with the frame 1, namely, the sealing layer 3 completely wraps the frame of the frame 1, so that the sealing effect is further improved.

Furthermore, every two frames 1 are connected through the convex parts 13 and the grooves 14 which are positioned at four corners, and the convex parts 13 and the grooves 14 are in one-to-one correspondence. The frames 1 are detachably connected, the protruding parts 13 are embedded into the grooves 14 to be stacked and combined, the frames are easy to detach, and the protruding parts 13 and the grooves 14 are located on the opposite sides between the two frames 1, so that the installation of the sealing layer 3 is not influenced. In addition, the four corners of the filter screen 2 are provided with through holes matched with the convex parts 13. The raised portion 13 can also provide the installation and positioning of the filter screen 2, so as to prevent the filter screen 2 from being easily deviated only by means of the fixing of the gap between the two frames 1.

Example 2

In the present embodiment, as shown in fig. 3, unlike embodiment 1, a plurality of frames 1 are stacked and combined, and through grooves 12 communicating with each other are formed on the outer sides of the peripheral frames thereof, and a sealant 3 is embedded in the through grooves 12, and the surface of the sealant 3 is not lower than the outer edge of the frame 1. The sealing layer 3 is fixedly embedded in the through groove 12, so that a gap possibly generated between the frame 1 and a mounting position is filled by utilizing an adhesive material on the sealing layer or slightly protruding out of the edge of the outer side of the frame 1, a good sealing effect can be achieved, the mounting is convenient, materials are saved, the mounting position except the structure needs to provide a good positioning effect for the whole filter screen structure, for example, the sealing layer is mounted in a filter device, and the filter device needs to be provided with a plug-in groove which is matched with the filter device so that the structure can be inserted into the filter device.
