Description

Technical Field

[0001] This utility model belongs to the field of lubricating oil filtration technology, and in particular relates to a bag filter compatible filter element. Background Technology

[0002] Existing bag filters and cartridge filters use filter bags and cartridges as filtration elements, respectively. These two types of filters differ significantly in structure and are not interchangeable. For example, bag filters typically employ an open structure, with filter bags generally used for high-flow, low-precision preliminary filtration, suitable for intercepting larger particles. Cartridge filters, on the other hand, are mostly closed designs, with cartridges suitable for high-precision, low-flow fine filtration, used to remove tiny particles. Therefore, traditional cartridges cannot be directly applied to bag filters, limiting the improvement of bag filter precision. Furthermore, this incompatibility forces users to purchase different equipment for different filtration needs, increasing operating costs and maintenance complexity. Utility Model Content

[0019] To better understand the purpose, structure, and function of this utility model, a clear and complete description of this utility model will be provided below in conjunction with the accompanying drawings.

[0020] like Figures 1-4 A bag filter compatible filter element includes: a filter element body 1 and an adapter ring 2. The filter element body 1 is cylindrical and made of traditional filter element materials, such as glass fiber or stainless steel. Its filtration accuracy can be selected according to requirements. Specifically, the filter element body 1 includes side walls, a bottom plate 8, and a fixing plate 9, to... Figure 1With the direction as a reference, the bottom plate 8 is located at the lower part of the side wall, and the fixing plate 9 is located at the upper part; the side wall of the filter element body 1 includes an inner layer 6 and an outer shell 7, and filter holes are provided on the inner layer 6, the outer shell 7, and the bottom plate 8; the inner layer 6 and the outer shell 7 are both cylindrical and vertically connected, with their bottom ends connected to the bottom plate 8 of the filter element body 1 and their top ends connected to the fixing plate 9 of the filter element body 1. Filter material is provided between the inner layer 6 and the outer shell 7. The filter material can be a commonly used filter material for filter elements, as it is a mature technology and will not be described in detail here.

[0021] Furthermore, the fixed plate 9 has a U-shaped cross-section, with the interior of its two side walls connected to the outer wall of the outer shell 7 and the inner wall of the inner layer 6, respectively, and its inner top connected to the top of the outer shell 7 and the inner layer 6. The edge cross-section of the bottom plate 8 is also U-shaped, and it is connected to the outer wall of the outer shell 7 and the inner wall of the inner layer 6.

[0022] The filter element body 1 has an adapter ring 2 at its open end. The adapter ring 2 is used to connect with the filter bag mounting port of the bag filter 11. Specifically, the upper part of the fixing plate 9 has an adapter ring 2. The inner and outer diameters of the adapter ring 2 match the filter bag mounting port of the bag filter 11. It is made of metal and has sufficient strength and sealing performance. By setting the adapter ring 2, the filter element can be directly installed into the filter bag mounting port of the bag filter 11, replacing the filter bag. This successfully solves the structural incompatibility problem between the filter bag and the filter element, achieving multiple advantages such as high-precision filtration, versatility, economy, and environmental protection. It not only improves the filtration performance and operating efficiency of the equipment but also reduces maintenance costs and extends the equipment lifespan, while meeting the requirements of environmental protection and sustainable development.

[0023] In this embodiment, a connecting plate 3 is provided in the middle of the adapter ring 2. Both ends of the connecting plate 3 are connected to the inner wall of the adapter ring 2, and a fixing hole is provided in the middle of the connecting plate 3. A lead screw 4 is provided inside the filter element body 1. One end of the lead screw 4 is connected to the bottom plate 8 of the filter element body 1, and the other end passes through the fixing hole and is threadedly connected to the nut 5 located on the upper part of the connecting plate 3. That is, the adapter ring 2 can be fixed to the upper part of the filter element body 1 by the cooperation of the nut 5 and the lead screw 4. This structure makes the adapter ring 2 and the filter element body 1 detachably connected, which facilitates the replacement of adapter rings 2 of different sizes according to the size of the filter bag installation opening.

[0024] Additionally, the adapter ring 2 has multiple sealing teeth 10 on its end face opposite to the filter element body 1. The sealing teeth 10 are coaxial with the adapter ring 2, and a sealing groove is formed between adjacent sealing teeth 10.

[0025] When installing this filter element onto the bag filter 11, a sealing ring can be fitted onto the outer wall of the adapter ring 2. The other end of the sealing ring contacts and presses against the inner wall of the bag filter 11 to ensure a seal between the filter element and the housing of the bag filter 11. A sealing ring is installed at the lower end of the adapter ring 2 within the sealing groove, and the bottom of the sealing ring contacts and presses against the filter bag mounting opening to ensure a seal between the adapter ring 2 and the filter bag mounting opening. Specifically, the connection method between the adapter ring 2 and the filter bag mounting opening includes, but is not limited to, bonding or bolting, thereby fixing the filter element and preventing it from falling off. During use, lubricating oil enters from the oil inlet 12 of the bag filter 11, passes through the filter material of the filter element body 1, and impurities are intercepted inside the filter element. The filtered lubricating oil flows out from the oil outlet 13.
