Description

Technical Field

[0001] This utility model relates to the field of filter bags, specifically a multi-layered corrosion-resistant filter bag. Background Technology

[0002] Filter bags, as core components of industrial fluid filtration, are widely used in chemical, pharmaceutical, food, and wastewater treatment industries to intercept solid particles, suspended solids, and colloidal impurities, ensuring fluid purity and system operational stability. However, with increasing demands for filtration efficiency, corrosion resistance, and service life in industrial environments, traditional single-layer or simple multi-layer filter bags are gradually revealing their limitations. The shortcomings of existing technologies are mainly reflected in the following aspects:

[0003] Existing fan box systems often have the following problems in the gas filtration process: the connection structure between the air inlet and the filter device is fixed, making it difficult to adjust the length according to actual needs, resulting in insufficient installation flexibility;

[0004] Most filter components are fixed in design, requiring disassembly of the entire structure for replacement and maintenance, which is cumbersome, time-consuming, and affects equipment efficiency. Furthermore, the plasticity and filtration efficiency of filter bags are insufficient to meet the demands of complex operating conditions. Therefore, there is an urgent need for a fan box system that allows for flexible adjustment of connection length, quick replacement of filter components, and high-efficiency filtration. Utility Model Content

[0005] The purpose of this invention is to provide a multi-layered corrosion-resistant filter bag to solve the problems mentioned in the background art.

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

[0007] A multi-layered corrosion-resistant filter bag includes a top frame, a fan box fixedly connected to the center of the top of the top frame, a crossbar fixedly connected to the bottom of the fan box, a support frame fixedly connected to the center of the end of the crossbar away from the fan box, a connecting pipe 1 penetrating the center of the bottom of the support frame, a curved pipe 1 fixedly connected to the connecting pipe 1 away from the bottom of the fan box, a connecting pipe 2 fixedly connected to the end of the curved pipe 1 away from the connecting pipe 1, a connecting plate fixedly connected to the end of the connecting pipe 2 away from the curved pipe 1, and a triangular seat fixedly connected to the end of the connecting plate away from the connecting pipe 2.

[0008] As a further embodiment of this utility model: a filter bag is snapped into the mounting part of the triangular seat, an mounting groove is provided on the outer wall of the filter bag, a double-layer cylinder is fixedly connected to the bottom of the inner frame of the filter bag, and a filter chamber is installed in the center of the double-layer cylinder.

[0009] As a further improvement of this utility model: the number of double-layer cylinders is four sets, the four sets of double-layer cylinders are structurally and sized to match each other, and the inner frame of the filter bag is fixedly connected with an inner liner.

[0010] As a further embodiment of this utility model: a motor is installed at the drive end of the fan box, and a second curved pipe is installed on the outer wall of the fan box. A storage cylinder is fixedly connected to the end of the second curved pipe away from the fan box.

[0011] As a further improvement of this utility model: a cyclone fan is installed at the drive end of the motor, and the discharge port of the cyclone fan is fixedly installed with the curved pipe.

[0012] As a further improvement of this utility model: both the first connecting pipe and the second connecting pipe are in the shape of stretchable hoses, and the inner frame of the triangular seat has a through hole at one end near the second connecting pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model allows for the connection of a triangular base to an external filter bag. A double-layered cylinder is installed inside the filter bag to filter the passing gas. The mounting groove on the outer wall of the filter bag and the inner frame of the triangular base are fixed by a connecting strip, thereby assembling the triangular base and the filter bag. The inner lining sheet installed on the inner wall of the filter bag enhances the plasticity of the filter bag. Its structure is more optimized and its design is more reasonable.

[0015] This utility model features a quick-release design for the bending tube and connecting tube, allowing for flexible adjustment of the distance between the triangular base and the fan box to adapt to different installation scenarios. The filter chamber and double-layer cylinder adopt a detachable structure, allowing for filter element replacement without disassembling the entire filter bag, reducing maintenance costs and time. The double-layer cylinder and inner liner work together to enhance the filtration effect and bag structure stability. The triangular base and filter bag can be quickly assembled via connecting strips and mounting slots, requiring no complicated tools and improving installation efficiency.

[0016] This utility model allows for the adjustment of the overall length of the triangular base by pulling it according to the installation space requirements and using the tensioning structure of the bending tube one, connecting tube one, and connecting tube two to connect the triangular base to the filter bag. The base is then fixed by embedding the connecting strip into the installation groove to ensure a tight seal. Attached Figure Description

[0023] According to the installation space requirements, pull the triangular seat 10 and adjust the overall length through the tension structure of the bending tube 14, connecting tube 7 and connecting tube 2 11 to connect the triangular seat to the filter bag 8, and fix it by embedding the connecting strip 19 into the installation groove 20 to ensure sealing.

[0024] Please see Figures 1-3 A connecting plate 9 is fixedly connected to the end of the connecting pipe 11 away from the bending pipe 14. A triangular seat 10 is fixedly connected to the end of the connecting plate 9 away from the connecting pipe 11. A filter bag 8 is snapped into the mounting part of the triangular seat 10. An installation groove 20 is opened on the outer wall of the filter bag 8.

[0025] When disassembling the filter chamber, loosen the insertion interface 20 on the double-layer cylinder 17 and directly remove the filter chamber for cleaning or replacement. The liner 19 can be replaced according to the wear condition to enhance the reusability of the filter bag.

[0026] Please see Figures 1-3The bottom of the inner frame of the filter bag 8 is fixedly connected to a double-layer cylinder 17. A filter chamber 18 is installed in the middle of the double-layer cylinder 17. There are four sets of double-layer cylinders 17, and the four sets of double-layer cylinders 17 are matched in size. The inner frame of the filter bag 8 is fixedly connected to an inner liner 19. A motor 16 is installed at the drive end of the fan box 2. A curved pipe 15 is installed on the outer wall of the fan box 2. A storage cylinder 12 is fixedly connected to the end of the curved pipe 15 away from the fan box 2.

[0027] Start the motor 16 to drive the cyclone fan 5 to run. The gas enters from the inlet end 6 and is discharged into the storage cylinder 12 through the second curved pipe 15. When the gas passes through the filter bag 8, it is filtered by the double-layer cylinder 17 and the inner lining plate 19. Impurities are intercepted in the filter chamber 18.

[0029] The working principle of this utility model is as follows:

[0030] When in use, the motor 16 is turned on to drive the cyclone fan inside the fan box 2. The cyclone fan is used to draw gas from the air inlet end of the fan box 2 into the curved pipe 15. In the storage cylinder 12 at the discharge end, the connecting pipe 7, the curved pipe 14 and the connecting pipe 11 connected to the air inlet end of the fan box 2 are used for stretching connection, thereby changing the stretching length of the triangular seat 10.
