Description

Technical Field

[0001] This application relates to the field of filter bag technology, and specifically discloses a high-efficiency multi-layer foldable filter bag. Background Technology

[0002] A filter bag is a filter element that intercepts particulate matter or impurities in a fluid through a bag-like structure. It is widely used in industrial, laboratory and daily life scenarios, ranging from 1μm to hundreds of micrometers. For example, 3M products cover an accuracy of 1-200μm.

[0003] Current filter bags typically have a bag-like structure with only a single filtration port. This results in inefficient filtration because they do not achieve layer-by-layer filtration with a single filtration port or layer-by-layer filtration with decreasing filtration diameters. Consequently, the filtration accuracy is low, making them extremely inconvenient to use. Furthermore, common filter bags require connection to a liquid outlet port, and since they are made of flexible materials, this connection is inconvenient and presents a pain point. In view of this, the inventor has developed a high-efficiency, multi-layer, foldable filter bag.

[0004] This invention provides a high-efficiency, multi-layer, foldable filter bag to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem of low filtration accuracy of traditional filter bags.

[0006] To achieve the above objectives, this utility model provides the following basic solution:

[0007] A high-efficiency multi-layer foldable filter bag includes a filter bag assembly, which consists of several stacked filter bag groups. Adjacent filter bag groups are detachably connected. Each filter bag group contains a detachably connected filter bag body for filtering liquid. The filter bag group itself is spliced, and the filter bag body is fixed inside the filter bag group by magnetic compression through the splicing of the filter bag group itself.

[0008] Furthermore, the filter bags in the filter bag assembly have the same filtration port diameter.

[0009] Furthermore, the filter bags in the filter bag assembly have different filtration diameters, and the filtration diameters of the stacked filter bags decrease sequentially.

[0010] Furthermore, the filter bag assembly includes an upper cover and a lower base detachably connected to the upper cover. The upper cover has a threaded groove, and the lower base has an external threaded cylinder that matches the threaded groove. The external threaded cylinder in the previous filter bag assembly is threadedly connected to the threaded groove in the next filter bag assembly.

[0011] Furthermore, the top cover is engraved with a label, which indicates the filter diameter.

[0012] Furthermore, the filter bag body is installed in the bottom, the inner wall of the bottom is fixedly connected to a boss, and the inner wall of the bottom near the outside of the boss is provided with an internal thread. The bottom of the top cover is fixedly connected to a connecting cylinder with an external thread on its outer wall, and the connecting cylinder is threadedly connected to the inner wall of the bottom.

[0013] Furthermore, the filter bag body includes an outer frame and a filter screen fixed inside the outer frame. The outer frame includes a magnetic frame disposed near the filter screen and a compression frame disposed outside the magnetic frame. The magnetic frame is magnetically connected to the boss.

[0014] Furthermore, after the magnetic frame is magnetically connected to the boss, and the connecting cylinder is threadedly connected to the inner wall of the bottom, the filter bag body is squeezed by the bottom of the connecting cylinder.

[0015] Furthermore, the filter screen is a nylon monofilament mesh.

[0016] Furthermore, both the upper cover and the lower bottom are provided with passage openings, the diameter of which is the same as the outer diameter of the filter screen.

[0017] The principle and effect of this solution are as follows:

The product has a more comprehensive coverage accuracy and is suitable for filtering a wider variety of liquids.

[0020] 3. Compared with the existing technology, this device has a simple structure. This device is a foldable filter bag. As for the individual filter bag assembly, it is relatively easy to fix, install and disassemble.

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] The reference numerals in the accompanying drawings include: top cover 1, bottom 2, external threaded cylinder 4, label 5, threaded groove 6, passage 7, boss 8, filter bag body 9, filter bag mesh 901, magnetic frame 902, and compression frame 903.

[0027] Implementation, for example Figure 1 , Figure 2 and Figure 3 As shown:

[0028] A high-efficiency multi-layer foldable filter bag includes a filter bag assembly, which consists of several stacked filter bag groups. Adjacent filter bag groups are detachably connected. Each filter bag group has a detachably connected filter bag body 9 for filtering liquid. The filter bag group itself is spliced, and the filter bag body 9 is fixed inside the filter bag group by magnetic compression through splicing of the filter bag group itself.

[0029] Specifically: Regarding the filter bag assembly: The filter bag assembly includes an upper cover 1 and a lower base 2 detachably connected to the upper cover 1. The upper cover 1 has a threaded groove 6, and the lower base 2 is fixedly connected to an external threaded cylinder 4 that matches the threaded groove 6. The external threaded cylinder 4 in the previous filter bag assembly is threadedly connected to the threaded groove 6 in the next filter bag assembly.

[0030] The filter bag assembly is stacked vertically using the threaded groove 6 and the external threaded cylinder 4.

[0031] The filter bag bodies 9 in the filter bag assembly have the same filter port diameter:

[0032] When the filter bag bodies 9 in the filter bag group have the same filtration diameter, enhanced filtration is achieved to ensure filtration accuracy.

[0033] The filter bag bodies 9 in the filter bag group have different filtration diameters, and the filtration diameters of the stacked filter bag groups decrease sequentially.

[0034] When the filter bag bodies 9 in the filter bag group have different filtration diameters and the filtration diameters in the stacked filter bag groups decrease sequentially, the filtration pressure of the current diameter, i.e. the bottommost filtration diameter, is reduced, so that the particle size decreases layer by layer.

[0035] Since the filter bag assembly is stacked on top of each other and installed manually, a label 5 is engraved on the top cover 1 to ensure installation accuracy. The label 5 is marked with the filter diameter.

[0036] After the filter bag assembly is installed, connect the liquid outlet pipe to the top of the filter bag assembly and connect the liquid collection device to the filter bag assembly.

[0037] Regarding the top cover 1 and the bottom 2 which is detachably connected to the top cover 1: the filter bag body 9 is installed in the bottom 2, the inner wall of the bottom 2 is fixedly connected to a boss 8, and the inner wall of the bottom 2 near the outside of the boss 8 is provided with an internal thread. The bottom of the top cover 1 is fixedly connected to a connecting cylinder with an external thread on its outer wall, and the connecting cylinder is threadedly connected to the inner wall of the bottom 2.

[0038] The filter bag body 9 includes an outer frame and a filter screen fixed inside the outer frame. The outer frame includes a magnetic frame 902 disposed near the filter screen and a compression frame 903 disposed outside the magnetic frame 902. The magnetic frame 902 is magnetically connected to the boss 8.

[0039] When the connecting cylinder is threaded to the inner wall of the bottom 2, the magnetic frame 902 is magnetically connected to the boss 8 and the connecting cylinder will continuously approach and contact the extrusion frame 903, thereby magnetically extruding and fixing the filter bag body 9.

[0040] The filter screen in this application is a nylon monofilament mesh. Both the upper cover 1 and the lower bottom 2 are provided with a passage 7, and the diameter of the passage 7 is the same as the outer diameter of the filter screen.

[0041] 1. This case improves the connection stability of the filter screen and thus the filtration accuracy by changing the traditional connection relationship between the filter screen and the liquid outlet pipe;

[0042] 2. This case improves the filtration accuracy of the filter screen by reducing the filtration pressure on the filter screen through the stacking of filter bag groups;

[0043] 3. This invention achieves quick replacement and installation of the filter bag body 9 through a detachable filter bag body 9, and ensures the installation stability of the filter bag body 9 by magnetic compression fixation, thereby ensuring the filtration accuracy of the filter bag body 9.

[0044] This device solves the problem of low filtration accuracy of traditional filter bags.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
