Description
Technical Field
[0001] This utility model relates to the field of oil stain cleaning technology, and in particular to a thin-film oil stain removal device. Background Technology
[0002] Oil pollution control has always been a major concern in industrial production and daily life. Especially in scenarios that generate large amounts of oil pollution, such as restaurant kitchens and machine shops, efficient oil removal is crucial for maintaining environmental cleanliness, ensuring normal equipment operation, and protecting public health. Thin-film oil removal devices have emerged to address this need, aiming to provide a more effective solution for oil pollution control.
[0003] In existing oil spill treatment technologies, common mechanical structures include traditional filter screen devices and some simple adsorption devices. Filter screen devices mainly use physical interception to allow oil-containing fluid to pass through a filter screen with a certain pore size, blocking larger oil particles on one side of the filter screen. Simple adsorption devices mostly use common adsorption materials, such as activated carbon, which utilize the porous structure of their surface to adsorb oil molecules.
[0004] However, existing oil stain removal technologies have some problems in oil stain treatment. In the environment of machining workshops, the amount of oil fumes generated is large and unevenly distributed. Traditional oil stain treatment equipment is difficult to collect oil fumes efficiently. Due to the lack of effective collection methods, a large amount of oil fumes will escape into the air, which will not only cause indoor environmental pollution, but also adhere to the surface of kitchen equipment, forming a difficult-to-clean oil stain layer and shortening the service life of the equipment. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a thin-film oil stain removal device, which aims to improve the problem that existing oil stain removal devices are unable to efficiently collect oil fumes, thus leading to a decrease in oil stain removal efficiency.

Detailed Implementation
[0023] 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.
[0024] Reference Figure 1 - Figure 3 An embodiment of this utility model provides a thin-film oil stain removal device, including a smoke extraction pipe 1, a connecting cover 2 fixedly connected to the upper surface of the smoke extraction pipe 1, a thin film body 4 fixedly connected inside the smoke extraction pipe 1, a filter plate 8 disposed inside the smoke extraction pipe 1, a suction assembly disposed inside the smoke extraction pipe 1, a motor 7 disposed on the upper surface of the smoke extraction pipe 1, a stirring assembly disposed at the output end of the motor 7, the stirring assembly being used to fully disperse the oil fumes, the suction assembly including a smoke collection hood 6, the outer wall of the smoke collection hood 6 being fixedly connected to the inner wall of the smoke extraction pipe 1, a first suction structure 3 and a second suction structure 5 being fixedly connected inside the smoke extraction pipe 1, the first suction structure 3 and the second suction structure 5 being distributed on the upper and lower surfaces of the thin film body 4, the smoke collection hood 6 being fixedly connected to the input end and the output end of the first suction structure 3, the smoke collection hood 6 being fixedly connected to the input end and the output end of the second suction structure 5, the stirring assembly including a rotating column 9, the rotating column 9 being fixedly connected to the output end of the motor 7, a connecting rod 10 being fixedly connected to the outer wall of the rotating column 9, and a stirring blade 11 being fixedly connected to one side of the outer wall of the connecting rod 10;
[0025] Specifically, suction structures 3 and 5 utilize high-efficiency fan components. Their internal impellers are specially designed to generate powerful and stable suction. When they begin operation, they rapidly create a significant negative pressure environment inside the smoke extraction duct 1. This strong pressure difference forces the surrounding fumes to flow quickly towards the smoke collection hood 6. The smoke collection hood 6 employs a unique trumpet-shaped design with a large opening area, efficiently capturing fumes from different directions and greatly improving the collection range and efficiency. Simultaneously, the inner wall of the smoke collection hood 6 is smoothly treated, reducing resistance during the flow of fumes and ensuring that the fumes are collected in an orderly manner. The oil is guided to the upper and lower surfaces of the membrane body 4, making full use of the membrane's adsorption properties to remove oil stains. The rotating column 9 and the output end of the motor 7 are tightly connected by a high-strength coupling, ensuring stable power transmission. There will be no loosening or slippage during the operation of the motor 7, allowing the stirring blades 11 to fully cover the internal space of the smoke extraction pipe 1 during rotation, and to fully stir the oil fumes. The stirring blades 11 are arc-shaped and have a certain degree of surface roughness, which allows them to better contact with the oil fumes, breaking larger oil fumes into smaller particles. This increases the contact area between the oil fumes and the membrane body 4 and the subsequent filter plate 8, thereby improving the overall filtration and oil stain removal effect.
[0026] Reference Figure 1 and Figure 4A sliding strip 13 is fixedly connected to the upper surface of the filter plate 8. A docking groove 14 is opened inside the sliding strip 13. A docking rod 15 is provided inside the smoke pipe 1. The docking rod 15 is used to dock with the docking groove 14. A sliding block 18 is fixedly connected to the outer wall of the docking rod 15. A connecting strip 17 is fixedly connected to one side of the outer wall of the sliding block 18. A spring 16 is sleeved on the outer wall of the docking rod 15. A guide groove 20 is opened inside the docking rod 15. A fixed rod 19 is fixedly connected inside the smoke pipe 1. The fixed rod 19 is slidably connected to the inner wall of the guide groove 20. A connecting plate 12 is fixedly connected to one side of the outer wall of the filter plate 8.
[0027] Specifically, the fixed connection between the slide bar 13 and the upper surface of the filter plate 8 ensures that there will be no loosening during the operation of the device and the installation and disassembly of the filter plate 8. The size of the docking groove 14 is precisely matched with the docking rod 15, ensuring the tightness and stability of the connection between the two and preventing the filter plate 8 from shifting during operation. The docking rod 15 and the slide block 18 adopt an integrated design, which enhances the strength of the structure. The connecting strip 17 makes it easy for the operator to apply external force and easily drive the slide block 18 and the docking rod 15 to move. The spring 16 is made of a material with good elasticity and durability, which provides a stable clamping force for the docking rod 15 under normal working conditions, ensuring that the filter plate 8 is firmly installed. The cooperation between the guide groove 20 and the fixed rod 19 provides precise guidance for the movement of the docking rod 15, so that it can only slide on the predetermined trajectory, ensuring the smoothness of the filter plate 8 disassembly and installation process. The connecting plate 12 is convenient for the operator to hold when disassembling and installing the filter plate 8, improving the convenience of operation.
[0028] Working principle: When using the device, the fumes are first input through the smoke extraction pipe 1. After the fumes enter the smoke extraction pipe 1, the suction structure 3 and suction structure 5 inside it start to work, creating a strong negative pressure environment inside the smoke extraction pipe 1. At the same time, the smoke collection hood 6 can build an efficient fume collection system inside the smoke extraction pipe 1 by means of its tight connection with suction structure 3 and suction structure 5. At this time, the fumes in the surrounding environment quickly converge towards the smoke collection hood 6 under the action of pressure difference. As the fumes are continuously sucked into the smoke collection hood 6, under the guidance of the smoke collection hood 6, the fumes flow to the upper and lower surfaces of the membrane body 4. Due to the operation of the suction structures on the upper and lower surfaces of the membrane, the continuous suction of the two allows the fumes to pass through the membrane body 4 stably and evenly. In this process, the oil particles in the fumes come into contact with the membrane body 4. Due to the adsorption characteristics of the membrane, the oil is effectively attached to the membrane, thereby realizing the separation and removal of oil in the fumes.
[0029] When the oil fume is input into the duct, the motor 7 is started. The motor 7 drives the rotating column 9 to rotate, and the connecting rod 10 and stirring blade 11 on the outer wall of the rotating column 9 will rotate accordingly. The stirring blade 11 will stir the oil fume in the smoke extraction duct 1, thereby fully dispersing the oil fume. Then, the filter plate 8 can intercept and adsorb these dispersed oil fume particles by virtue of its own structure and material characteristics, thereby achieving preliminary filtration of oil fume and reducing the oil content in the subsequent exhaust gas.
[0030] When cleaning the filter plate 8 is required, the connecting strip 17 can be pulled first. The connecting strip 17 can drive the sliding block 18 to move, and the sliding block 18 can drive the docking rod 15 to move, so that the docking rod 15 will disengage from the docking groove 14 inside the sliding strip 13. At the same time, the spring 16 on the outer wall of the docking rod 15 will be stretched until the docking rod 15 is completely disengaged from the docking groove 14. The connecting plate 12 can then be pulled outward to pull out the filter plate 8, thus realizing the disassembly and cleaning of the filter plate 8. After cleaning, the filter plate 8 is inserted into the smoke pipe 1 through the sliding strip 13, and then the connecting strip 17 is released. Under the elastic action of the spring 16, the docking rod 15 is re-clamped into the docking groove 14, thus realizing the installation of the filter plate 8.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
