[0032] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] refer to Figure 1-3An environmentally friendly device for recovering oil mist from an automatic oil sprayer includes a recovery hood 1, a recovery pipe 4, a filter assembly 5, an exhaust pipe 6, and an exhaust fan 7. The recovery hood 1 is fixed on a movable frame 2 and can be secured with bolts. The recovery hood 1 can be made of stainless steel and can move with the movable frame 2. The recovery hood 1 has multiple spray rods 3 inside, providing space for the initial collection of oil mist. The movable frame 2 is the movable structure of the oil sprayer. The movable frame 2 and the spray rods 3 are existing structures of the oil sprayer and are prior art, so they will not be described in detail here. The filter assembly 5 is located on the movable frame 2 and can filter and purify the oil mist. The recovery pipe 4 is located between the recovery hood 1 and the filter assembly 5 and is used to transport the oil mist. The recovery pipe 4 is made of stainless steel corrugated pipe. The exhaust pipe 6 is connected to the filter assembly 5 and can be a flexible hose that can bend during the movement of the filter assembly 5 to ensure smooth flow of oil mist. The exhaust fan 7 is connected to the exhaust pipe 6. The exhaust fan 7 can be a centrifugal exhaust fan. Under the action of the exhaust fan 7, a negative pressure airflow is formed, which drives the oil mist from the recovery hood 1 through the recovery pipe 4, the filter assembly 5, the exhaust pipe 6 and the exhaust fan 7 in sequence, so as to realize the recovery and purification of the oil mist and discharge it to the external environment, thereby avoiding the oil mist from threatening the health of the operators and polluting the environment.

[0034] In some embodiments, the recovery hood 1 includes a hood body 11, a fixing groove 12, and a suction port 13. The hood body 11 is the main structure of the recovery hood 1. Multiple oil spray rods 3 are provided inside the hood body 11, and the bottom of the oil spray rods 3 is higher than the bottom of the hood body 11. The bottom shape of the hood body 11 is adapted to the surface of the mold to be sprayed, which can form a relatively sealed spraying space during the spraying process, facilitating the recovery of oil mist. The fixing groove 12 penetrates one inner wall of the hood body 11 and is provided with a movable frame 2, which can realize a stable connection between the recovery hood 1 and the movable frame 2. A silicone sealing strip can be set on the contact surface between the fixing groove 12 and the movable frame 2. With the help of negative pressure adsorption, a dynamic sealing environment is formed, which can improve the adsorption force inside the recovery hood 1. The suction port 13 is located at the top of the hood body 11 and is the key channel for oil mist to enter the recovery system. Under the negative pressure generated by the exhaust fan 7, the oil mist inside the hood body 11 will converge towards the suction port 13 and enter the filter assembly 5 through the recovery pipe 4. The suction port 13 is designed to be located at the top, which conforms to the natural upward trend of oil mist inside the cover 11 and can improve the collection efficiency of oil mist.

[0035] In some embodiments, the recycling hood 1 further includes a limiting block 14, which is disposed on the inner wall of the hood 11 on the side away from the fixing groove 12 and pressed onto the movable frame 2. This can further enhance the connection stability between the recycling hood 1 and the movable frame 2, prevent the recycling hood 1 from shaking or shifting on the movable frame 2, and ensure the stability of the oil mist recycling process.

[0036] In some embodiments, the filter assembly 5 includes a fixed barrel 51, a filter chamber 52, a filter element 53, an air inlet 54, and an air outlet 55. The fixed barrel 51 is mounted on the movable frame 2, the filter chamber 52 is located inside the fixed barrel 51, and the filter element 53 is located inside the filter chamber 52. The filter chamber 52 provides an installation position for the filter element 53. Oil mist is intercepted and adsorbed by the filter element 53 in the filter chamber 52, achieving separation of oil dust from air. The air inlet 54 penetrates through the bottom of the fixed barrel 51 and is connected to the recovery pipe 4. The air outlet 55 penetrates through the top of the fixed barrel 51 and is connected to the exhaust pipe 6. The air inlet 54 and the air outlet 55 form a flow channel for oil mist within the filter assembly 5. Under the negative pressure of the exhaust fan 7, the oil mist enters the filter chamber 52 from the air inlet 54, is filtered by the filter element 53, and clean air is discharged from the air outlet 55.

[0037] In some embodiments, the filter assembly 5 further includes a recovery port 56 and a recovery plug 57. The recovery port 56 extends through the bottom of the fixed barrel 51 and is used to collect oily dust intercepted during the filtration process. The recovery plug 57 seals the recovery port 56 and is detachably connected to the recovery port 56. When it is necessary to clean the oily dust in the filter assembly 5, the recovery plug 57 can be opened to discharge the material, thereby recovering the oily release agent.

[0038] In some embodiments, the fixed bucket 51 includes a bucket body 511 and a bucket cover 512. Both the bucket body 511 and the bucket cover 512 can be made of polypropylene, which has good chemical stability and corrosion resistance and is suitable for filtering oil mist environments. The bucket body 511 is provided with an air inlet 54, which is connected to the recovery pipe 4 to receive oil mist transmitted from the recovery hood 1. The bucket cover 512 is provided with an air outlet 55, which is connected to the exhaust pipe 6. The filtered and purified air is discharged from the air outlet 55. The bucket cover 512 is detachably connected to the bucket body 511 and can be fixed by bolts, which facilitates the periodic replacement or cleaning of the filter element 53.

[0039] In some embodiments, the filter element 53 includes multiple coarse filter screens 531 and fine filter screens 532. The multiple coarse filter screens 531 are coaxially arranged in the filter chamber 52. The coarse filter screens 531 can be made of 30PPi stainless steel wire mesh with a pore size of 20mm, which can intercept larger oil dust particles and play a preliminary filtration role. The fine filter screens 532 are arranged above the multiple coarse filter screens 531. The fine filter screens 532 can be made of 35PPi polyester fiber mesh with a pore size of 15mm, which can finely filter the oil mist after coarse filtration, further remove fine oil dust particles, and ensure that the discharged air meets environmental protection standards. Through multi-layer filtration, oil dust is filtered from large to small, thereby improving the overall filtration efficiency.

[0040] In some embodiments, the filter assembly 5 further includes a support ring 58 and a compression ring 59. The support ring 58 is coaxially disposed at the bottom of the barrel 511 to support the filter element 53 and ensure the stable installation of the filter element 53 in the filter chamber 52. The compression ring 59 is coaxially disposed at the bottom of the barrel cover 512 and presses against the filter element 53 to fix the filter element 53, preventing the filter element 53 from shifting under airflow impact and ensuring the filtration effect. The support ring 58 and the compression ring 59 may be made of polypropylene and can be integrally molded with the fixed barrel 51 by injection molding or installed by threaded connection.

[0041] The specific working principle is as follows:

[0042] When the automatic oil sprayer is working, the exhaust fan 7 starts simultaneously. The spray bar 3 mixes the oily release agent with high-pressure air and sprays it onto the mold surface. Some of the release agent that does not adhere to the mold forms oil mist that diffuses within the recovery hood 1. At this time, a negative pressure is formed within the exhaust pipe 6 and the filter assembly 5. Under the action of negative pressure, the oil mist in the recovery hood 1 flows towards the dust inlet 13 and enters the air inlet 54 of the filter assembly 5 through the recovery pipe 4. After entering the filter chamber 52, the oil mist first passes through multiple coarse filter screens 531, where larger oil dust particles are intercepted. Subsequently, the oil mist, after preliminary filtration, continues to flow upward and passes through the fine filter screen 532, where finer oil dust particles are also effectively intercepted. The clean air after multiple layers of filtration enters the exhaust pipe 6 from the air outlet 55 and is finally discharged from the device by the exhaust fan 7. During the filtration process, the intercepted oil dust impurities gradually accumulate at the bottom of the filter chamber 52 and can be discharged from the recovery port 56 by opening the recovery plug 57.
