Abstract
Description
Technical Field
[0001] This utility model relates to the field of air filter technology, specifically to an air filter with reusable mating flanges. Background Technology
[0002] Air filters are common filtration devices, generally consisting of a conical body made of perforated plates, with a filter screen installed on the inner side of the conical body. Traditional air filters have low flow rates, high filtration resistance, and low filtration efficiency. Furthermore, due to the large size of high-temperature air filters (2 meters in diameter at the base and 2.4 meters in height), the filter screen needs to be fixed to the conical body to increase the overall strength and stability of the filter. The conventional method is to fix the air filter between two flanges in the pipeline. However, this method results in a large air filter structure and a large flange structure, requiring the entire flange to be replaced after replacement, leading to significant material consumption and making maintenance and replacement inconvenient. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide an air filter element with reusable mating flanges. It has a simple structure, is easy to install, can effectively reduce the weight during installation, the mating flanges can be reused, and there is no need to completely disassemble the device, which makes the maintenance effect better and can effectively solve the problems in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an air filter element with a reusable mating flange, comprising a pipeline mating flange connected to a pipeline, an annular groove provided on one side of the pipeline mating flange, a filter element flange disposed inside the annular groove, the inner diameter of the pipeline mating flange being not less than the inner diameter of the filter element flange, a conical filter element fixedly disposed inside the filter element flange, screw holes evenly provided on the pipeline mating flange and the filter element flange, and the screw holes on the pipeline mating flange corresponding one-to-one with the screw holes on the filter element flange, and the corresponding screw holes of the pipeline mating flange and the filter element flange being fixed by countersunk screws.
[0005] Furthermore, a rubber sealing gasket is provided between the pipeline mating flange and the filter element flange, and the rubber sealing gasket is provided with a through hole corresponding to the countersunk screw.
[0006] Furthermore, the filter element flange and the pipeline mating flange are located on the same plane, and the end face of the countersunk screw is located inside the screw hole on the filter element flange.
[0007] Furthermore, the conical filter element includes a conical skeleton, the open end of which is welded to the inner side of the filter element flange, and a filter screen is provided on the outer side of the conical skeleton.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: First, the pipe mating flange of the device is installed between the flanges of the two pipes. Then, the filter element flange is fixed inside the groove of the pipe mating flange. Finally, the pipe mating flange and the filter element flange are fixed together with countersunk screws, which facilitates the disassembly of the conical filter element and makes the maintenance of the conical filter element more convenient. The air filter element with reusable mating flange has a simple structure and is easy to install. It can effectively reduce the weight during installation. The mating flange can be reused and there is no need to completely disassemble the device, which makes the maintenance effect better. Attached Figure Description

[0011] 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.
[0012] Please see Figure 1-4This utility model provides a technical solution: an air filter element with a reusable mating flange, including a pipe mating flange 4 connected to a pipeline. An annular groove is provided on one side of the pipe mating flange 4, and a filter element flange 5 is disposed inside the annular groove. The inner diameter of the pipe mating flange 4 is not less than the inner diameter of the filter element flange 5. A conical filter element 1 is fixedly disposed inside the filter element flange 5. Screw holes are evenly distributed on both the pipe mating flange 4 and the filter element flange 5, and the screw holes on the pipe mating flange 4 correspond one-to-one with the screw holes on the filter element flange 5. The corresponding screw holes on the pipe mating flange 4 and the filter element flange 5 are fixed by countersunk screws 2. A rubber sealing gasket 3 is provided between the pipe mating flange 4 and the filter element flange 5, and the rubber sealing gasket 3 has through holes corresponding to the countersunk screws 2. The filter element flange 5 and the pipe mating flange 1 are then connected. One side of flange 4 is located on the same plane, and the end face of countersunk screw 2 is located inside the screw hole on filter element flange 5. Conical filter element 1 includes a conical skeleton 11. The open end of the conical skeleton 11 is welded to the inner side of filter element flange 5, and a filter screen 12 is provided on the outer side of the conical skeleton 11. First, the pipeline mating flange 4 of the device is installed between the flanges of the two pipelines. Then, the filter element flange 5 is fixed inside the groove of the pipeline mating flange 4. Then, the pipeline mating flange 4 and the filter element flange 5 are fixed together by countersunk screw 2, which facilitates the disassembly of conical filter element 1 and makes the maintenance of conical filter element 1 more convenient. This reusable mating flange air filter element has a simple structure and is easy to install. It can effectively reduce the weight during installation. The mating flange can be reused and does not require the entire device to be disassembled, making maintenance more convenient.
