Description

Technical Field

[0001] This utility model relates to the field of oil fume and dust filtration and separation technology, specifically a filter screen for separating oil fumes and dust. Background Technology

[0002] In scenarios involving oil fumes and dust, pollutants need to be separated by filter screens to meet emission standards. The fiber felt in the staged filter box is the core filter medium and needs to be replaced regularly to maintain filtration efficiency. Currently, most filter screens adopt an integrated structure, relying on fiber felt to intercept oil fumes and dust of different particle sizes step by step to ensure that the particulate matter content in the emitted gas meets environmental protection standards.

[0003] However, existing filter discs in the grading filter box lack an independent replacement structure. Replacement requires complete disassembly and replacement of all fiber felts. Even if only a single fiber felt fails, other unfailed media must be discarded, resulting in serious waste of consumables and significantly increasing operating costs. At the same time, grading filter boxes mostly use traditional sealing methods such as bolt fixing, which require repeated operation with tools when opening or closing, resulting in poor convenience and a time-consuming fiber felt replacement process. This not only reduces maintenance efficiency but also affects the overall pollutant treatment progress due to prolonged downtime. Therefore, there is an urgent need for a filter disc for separating oil fumes and dust to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a filter screen for separating oil fumes and dust, so as to solve the problems mentioned in the background art of the lack of independent replacement structure and complicated replacement method of the existing filter screen's graded filter box.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filter screen for separating oil fumes and dust, comprising a mounting frame, a graded filter box fixedly connected to the top surface of the mounting frame, a zeolite rotor fixedly connected to the top surface of the mounting frame, a catalytic furnace fixedly connected to the top surface of the mounting frame, and a mixing tank fixedly connected to the top surface of the catalytic furnace; the filter screen for separating oil fumes and dust further includes: An independent replacement component is provided inside the grading filter box and is used to independently replace the filter media inside the grading filter box. A quick-sealing assembly is disposed on the top surface of the grading filter box for quickly opening or closing the grading filter box.

[0006] Preferably, the independent replacement component includes a sliding box, which is disposed on the inner wall of the graded filter box. The sliding box has multiple placement boxes inside, and the inner wall of the sliding box has multiple limiting grooves. The placement boxes are slidably connected to the inner walls of the limiting grooves, and the inner walls of the multiple placement boxes are respectively provided with fiber felt of different densities.

[0007] Preferably, the quick-sealing assembly includes a sealing cover, which is disposed on the top surface of the grading filter box. The top surface of the grading filter box has multiple mounting slots, and magnetic blocks are fixedly connected to the inner wall of the mounting slots. All of the magnetic blocks are magnetically connected to the sealing cover.

[0008] Preferably, the bottom surface of the sealing cover is provided with a fixing groove, and a sealing ring is fixedly connected to the inner wall of the fixing groove, with the bottom surface of the sealing ring abutting against the top surface of the sliding box.

[0009] Preferably, the inner wall of the graded filter box is provided with an embedding groove, and the sliding box is slidably connected to the inner wall of the embedding groove.

[0010] The sealing cover is larger than the sliding box, and the sealing cover is made of iron-nickel alloy.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The independently replaceable components facilitate the individual replacement of the fiber felt inside the grading filter box, thereby reducing consumable waste, lowering operating costs, and ensuring consistently good filtration efficiency while improving maintenance flexibility.

[0014] 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.

[0015] Please see Figures 1-5 This utility model provides a filter screen for separating oil fumes and dust, including a mounting frame 1, a graded filter box 2 fixedly connected to the top surface of the mounting frame 1, a zeolite rotor 3 fixedly connected to the top surface of the mounting frame 1, a catalytic furnace 5 fixedly connected to the top surface of the mounting frame 1, and a mixing tank 4 fixedly connected to the top surface of the catalytic furnace 5. The filter screen for separating oil fumes and dust also includes: Independent replacement component, which is located inside the graded filter box 2, is used to independently replace the filter media inside the graded filter box 2. A quick-sealing assembly is located on the top surface of the grading filter box 2 and is used to quickly open or close the grading filter box 2.

[0016] Furthermore, the independently replaceable components facilitate the independent replacement of the filter media inside the grading filter box 2, thereby reducing consumable waste, lowering operating costs, and ensuring consistently good filtration efficiency while improving maintenance flexibility. Additionally, the quick-sealing components facilitate the rapid opening or closing of the grading filter box 2, thereby improving the ease of opening or closing the grading filter box 2. By improving the ease of opening or closing the grading filter box 2, the replacement efficiency of the filter media inside the grading filter box 2 is further improved. The zeolite rotor 3, mixing tank 4, and catalytic furnace 5 are common adsorption, mixing, and catalytic components. After being filtered by the staged filter box 2 and humidified by the mixing tank 4, the exhaust gas enters the zeolite rotor 3 for adsorption. The zeolite rotor 3 is divided into three areas: an adsorption area, which occupies 5 / 6 of the total area, where organic gases are adsorbed in the honeycomb zeolite and clean gas is discharged; a desorption area, which occupies 1 / 2 of the rotor, is heated at high temperature to volatilize VOCs in the gas; and a cooling area, which occupies another 1 / 2 of the rotor, where the cooled outlet gas exchanges heat with the high-temperature flue gas to 200°C before entering the desorption area to form desorbed gas. The desorbed gas is a high-concentration organic gas, which is thermally oxidized by the catalytic furnace 5 to form carbon dioxide and water, meeting emission standards. At the same time, the thermal oxidation releases a large amount of heat, which not only meets the operating requirements of the catalytic furnace 5 itself but also provides desorption heat for the zeolite rotor. The zeolite rotor 3, mixing tank 4, and catalytic furnace 5 are considered prior art in this application and will not be described in detail here.

[0017] Furthermore, the independently replaceable component includes a sliding box 601, which is disposed on the inner wall of the grading filter box 2. The sliding box 601 contains multiple placement boxes 602, and its inner wall has multiple limiting grooves 603. The placement boxes 602 are slidably connected to the inner walls of the limiting grooves 603. The inner walls of the multiple placement boxes 602 are respectively lined with fiber felt of different densities. The inner wall of the grading filter box 2 has an embedding groove 604. The sliding box 601 is slidably connected to the inner wall of the embedding groove 604. Through the independently replaceable components, multiple placement boxes 602 with different densities of fiber felt allow for graded filtration of oil fumes and dust in the exhaust gas. The placement boxes 602 are slidably connected inside the left and right limiting grooves 603, facilitating the limiting of the placement boxes 602 and maintaining a constant interval between them. This ensures that all placement boxes 602 maintain good filtration performance. Simultaneously, the multiple placement boxes 602 are slidably connected to the inner wall of their corresponding limiting grooves 603, facilitating the filtration of oil fumes and dust in the exhaust gas. When the fiber felt filter inside a certain placement box 602 becomes saturated, the corresponding placement box 602 can be removed individually, making it easier to replace only the failed filter media, thereby reducing consumable waste and lowering operating costs. At the same time, it can continuously maintain good filtration efficiency and improve maintenance flexibility. Secondly, the embedded groove 604 makes it easy to limit the sliding box 601. At the same time, the sliding box 601 is embedded in the inner wall of the embedded groove 604. When a major cleaning of the inside of the graded filter box 2 is required, the sliding box 601 can be directly removed from the inner wall of the embedded groove 604, which improves the convenience of cleaning the inner wall of the graded filter box 2.

[0018] Furthermore, the quick-sealing assembly includes a sealing cover 701, which is disposed on the top surface of the grading filter box 2. The top surface of the grading filter box 2 has multiple mounting grooves 702, and magnetic blocks 703 are fixedly connected to the inner walls of the mounting grooves 702. All magnetic blocks 703 are magnetically connected to the sealing cover 701. The bottom surface of the sealing cover 701 has a fixing groove 704, and a sealing ring 705 is fixedly connected to the inner wall of the fixing groove 704. The bottom surface of the sealing ring 705 abuts against the top surface of the sliding box 601. The size of the sealing cover 701 is larger than that of the sliding box 601. The sealing cover 701 is made of an iron-nickel alloy. Made of high-quality materials, the quick-sealing component allows the sealing cover 701 and the magnetic block 703 to work together to facilitate the quick opening or closing of the grading filter box 2, thereby improving the convenience of opening or closing the grading filter box 2. By improving the convenience of opening or closing the grading filter box 2, the replacement efficiency of the fiber felt inside the grading filter box 2 is improved. The sealing ring 705 facilitates the sealing effect between the sealing cover 701 and the sliding box 601, preventing gas from escaping from between the sliding box 601 and the sealing cover 701. It should be noted that the iron-nickel alloy sealing cap 701, while maintaining a good magnetic attraction effect with the magnetic block 703, also has good resistance to oil fume corrosion.

[0019] Working Principle: During use, the independently replaceable components allow for the graded filtration of oil fumes and dust in exhaust gas through fiber felts of varying densities within multiple placement boxes 602. The placement boxes 602 are slidably connected within two limiting grooves 603, facilitating positioning of the boxes and maintaining a constant interval between them. This ensures that all placement boxes 602 maintain good filtration performance. Simultaneously, the sliding connection between the multiple placement boxes 602 and the inner walls of their corresponding limiting grooves 603 allows for placement in one of them. When the fiber felt filter inside box 602 is saturated, the corresponding box 602 can be removed individually, making it easier to replace only the failed filter media, thereby reducing consumable waste and lowering operating costs. At the same time, it can continuously maintain good filtration efficiency and improve maintenance flexibility. Secondly, the embedded groove 604 makes it easy to limit the sliding box 601. The sliding box 601 is embedded in the inner wall of the embedded groove 604. When a major cleaning of the inside of the graded filter box 2 is required, the sliding box 601 can be directly removed from the inner wall of the embedded groove 604, which improves the convenience of cleaning the inner wall of the graded filter box 2.

[0020] Furthermore, the quick-sealing component allows the sealing cover 701 and the magnetic block 703 to work together to facilitate the quick opening or closing of the grading filter box 2, thereby improving the convenience of opening or closing the grading filter box 2. By improving the convenience of opening or closing the grading filter box 2, the replacement efficiency of the fiber felt inside the grading filter box 2 is improved. The sealing ring 705 facilitates the sealing effect between the sealing cover 701 and the sliding box 601, preventing gas from escaping between the sliding box 601 and the sealing cover 701.
