Description

Technical Field

[0001] This utility model relates to the field of air filtration technology for computer room air conditioning, and in particular to a bag filter structure. Background Technology

[0002] Currently, the most commonly used filters in computer rooms are folded-down filters and flat filters, which are generally installed directly on the air inlet surface of the heat exchanger. Folded-down filters are made of filter material with a certain bending shape and are fixed to the air inlet surface of the heat exchanger. When air enters the air conditioning unit, it first passes through the folded-down filter, where dust, particulate matter, and other impurities in the air are intercepted. The filtered air then enters the heat exchanger for heat exchange. Flat filters use a relatively flat filter structure and are also fixed to the air inlet surface of the heat exchanger.

[0003] Despite its folded design, the effective filtration area of ​​the filter screen remains relatively small in practical applications. This limits its ability to filter air pollutants, especially when faced with high concentrations of polluted air, where the filtration effect is poor. Because the existing screen is installed on the heat exchanger's air inlet surface, in dusty environments, unfiltered air will directly enter the air conditioner's indoor unit before being filtered by the folded screen. Over time, this leads to a large accumulation of dust inside the air conditioner's indoor unit, severely affecting the normal operation of internal components, shortening equipment lifespan, and increasing maintenance costs. Furthermore, the existing filter screen, installed on the heat exchanger's air inlet surface, requires opening the unit for disassembly. This process demands skilled personnel and involves cumbersome steps; slight errors can damage the unit. In dusty and harsh environments like steel mills, the filter screen needs frequent replacement. The need to open the unit each time it's disassembled further highlights the complexity and difficulty of the operation.

[0004] To address the shortcomings of existing technologies, a bag filter structure needs to be designed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bag filter structure.

[0006] A bag filter structure includes a support frame, a cover plate fixed to the top of the support frame, and a bag filter disposed within the support frame. The support frame is a square frame with two filter guide rails inside. The bag filter includes a frame, several crossbars, and several triangular filter bags. The crossbars are fixed inside the frame, and the triangular filter bags include an air inlet end and an air outlet end. The air inlet end is quadrilateral, and the air outlet end is linear. The four sides of the air inlet end are respectively fixed to the frame and the crossbars. The frame is inserted into the filter guide rails so that the bag filter can be detachably installed within the support frame.

[0007] Furthermore, the triangular filter bags are arranged sequentially within the frame, and every two triangular filter bags share a horizontal bar.

[0008] Furthermore, the support frame includes a first upper mounting beam, a second upper mounting beam, two fixed upper side beams, a first lower mounting beam, a second lower mounting beam, two fixed lower side beams, and several vertical beams. The two ends of the fixed upper side beams are welded to the first and second upper mounting beams respectively to form a square upper frame. The fixed lower side beams are welded to the first and second lower mounting beams respectively to form a square lower frame. Several vertical beams are welded to the square upper frame and the square lower frame respectively. The filter guide rail is located near the second upper mounting beam.

[0009] Furthermore, the triangular filter bag is made of chemical fiber, and the frame is made of galvanized iron sheet.

[0010] Furthermore, the filter guide rail is U-shaped, with filter front baffles at both ends.

[0011] Furthermore, plastic corner connectors are provided at the corners of the frame.

[0012] Beneficial effects: This utility model effectively reduces and avoids dust accumulation inside the air conditioner by setting a bag filter and installing it on the outside of the unit through a support frame. At the same time, it does not require disassembly of the unit, making installation and replacement convenient, economical, and ensuring the normal operation of internal components and equipment, extending the service life of the equipment, and reducing maintenance costs. Moreover, the bag filter has a large filtration area and good sealing effect, which further improves the filtration efficiency. The triangular filter bag has a quadrilateral air inlet and a linear air outlet, ensuring that air can enter smoothly while ensuring the filtration effect. Attached Figure Description

[0018] 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.

[0019] Please refer to Figures 1-3 This embodiment proposes a bag filter structure, including a support frame 1, a cover plate 2 fixed to the top of the support frame 1, and a bag filter 3 disposed within the support frame 1. The cover plate 2 has an oblong hole, and the support frame 1 has a hexagonal hole with a nut riveted to it at a corresponding position. The filter is fixed to the support frame 1 using combination screws through the oblong hole and the hexagonal hole, ensuring a secure connection even after multiple disassemblies and reassemblies. The combination screw consists of a screw, a flat washer, and a spring washer. The screw is responsible for tightening, the flat washer increases the contact area and protects the connection surface, and the spring washer uses elasticity to prevent loosening. These three components work together to ensure a stable and reliable connection, meeting assembly requirements. The support frame 1 is a square frame with two filter guide rails 4 inside. The filter guide rails 4 are U-shaped, with filter front baffles at both ends. The bag filter 3 includes a frame 31, several crossbars 32, and several triangular filter bags 33. Plastic corner connectors are provided at the corners of the frame 31, and the crossbars 32 are fixed inside the frame 31, ensuring the strength of the frame 31 while facilitating the installation of the triangular filter bags 33. The triangular filter bag 33 includes an inlet end and an outlet end. The inlet end is quadrilateral, and the outlet end is linear, ensuring that air can enter over a large area while maintaining filtration efficiency. The four sides of the inlet end are respectively fixed to the frame 31 and the crossbar 32. The frame 31 is inserted into the filter guide rail 4, allowing the bag filter 3 to be detachably installed in the support frame 1. Several triangular filter bags 33 are arranged sequentially in the frame 31, with each pair of triangular filter bags 33 sharing a crossbar 32, ensuring that all air can be filtered through the triangular filter bags 33 without any leakage. The triangular filter bags 33 are made of chemical fibers, which can effectively intercept impurities and improve filtration efficiency. The frame 31 is made of galvanized iron sheet. By setting the bag filter 3 and installing it on the outside of the unit through the support frame 1, dust accumulation inside the air conditioner is effectively reduced and avoided. At the same time, it does not require disassembling the unit for easy installation and replacement, is economical and affordable, ensures the normal operation of internal components and equipment, extends equipment life, and reduces maintenance costs. Moreover, the bag filter 3 has a large filtration area and good sealing effect, further improving filtration efficiency.

[0020] The support frame 1 includes a first upper mounting beam 11, a second upper mounting beam 12, two fixed upper side beams, a first lower mounting beam 13, a second lower mounting beam 14, two fixed lower side beams, and several vertical beams 15. All beams employ a flange structure, enabling the support frame 1 to tightly connect the air duct to the computer room air conditioning system. This reduces airflow leakage and resistance at the connection points, resulting in smoother and more stable airflow transmission, optimizing the aerodynamic performance of the air conditioning system, and improving overall operating efficiency. The two ends of the fixed upper side beams are welded to the first upper mounting beam 11 and the second upper mounting beam 12 respectively to form a square upper frame. The fixed lower side beams are welded to the first lower mounting beam 13 and the second upper mounting beam 14 respectively to form a square upper frame. The beam 13 and the second mounting lower crossbeam 14 are welded together to form a square lower frame. Several vertical beams 15 are welded to the square upper frame and the square lower frame respectively. The filter guide rail 4 is set near the second mounting upper crossbeam 12. Several mounting holes are opened on the support frame 1. This utility model is applicable to units with top air supply and front return air. Several support frames 1 can be set according to the actual situation. The support frame 1 is fixed to the unit through the mounting holes on one side of the first mounting upper crossbeam 11 using self-tapping locking screws, ensuring that all air intake enters from the air intake end. The gas completes efficient filtration when flowing through the triangular filter bag 33 before entering the unit. This ensures the stability and standardization of the airflow path, allowing the filtration efficiency of the triangular filter bag 33 to be fully utilized, providing a solid guarantee for the stable operation of the unit.
