Description

Technical Field

[0001] This utility model relates to the technical field of waste gas separation devices, and in particular to a waste gas separation device for basic epoxy resin production. Background Technology

[0002] In the production of basic epoxy resins, waste gas treatment is a crucial and highly challenging aspect. During the production process, especially in key steps such as mixing, large quantities of waste gases containing various harmful substances, such as benzene compounds and phenols, are generated. These waste gases not only pollute the production workshop environment and endanger the health of operators, but also have a serious negative impact on the surrounding atmospheric environment. With increasingly stringent environmental protection requirements, how to efficiently and thoroughly treat the waste gases generated during the production of basic epoxy resins has become an urgent problem to be solved in the industry. Developing a device that can effectively separate and filter waste gases is of great significance for ensuring the sustainability of production, meeting environmental regulations, and enhancing the company's social image.

[0003] Traditional methods for treating waste gas from basic epoxy resin production mainly rely on simple ventilation and filtration devices. Ventilation typically involves using large exhaust fans to extract waste gas from the production equipment and then directly discharge it to the outside. Filtration devices generally use filter screens or other filter media that are fixedly installed in pipes. When the waste gas passes through these filter media, some impurities and harmful substances are adsorbed.

[0004] However, existing technologies suffer from poor waste gas treatment performance. Traditional fixed filtration devices, due to their stationary filter media, allow waste gas to only come into contact with a portion of the filter surface as it passes through, failing to fully interact and react with the filter media. This results in incomplete filtration and adsorption of impurities and harmful substances in the waste gas. In particular, the waste gas generated during the basic epoxy resin mixing process is complex, containing various fine particles and chemical substances, leading to a large amount of insufficiently treated waste gas being emitted into the environment, causing serious pollution. Therefore, a waste gas separation device for basic epoxy resin production is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a basic epoxy resin production waste gas separation device, which aims to improve the problem in the prior art that the waste gas can only contact a part of the filter screen surface when passing through, and cannot fully contact and react with the filter medium, resulting in poor treatment effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A waste gas separation device for basic epoxy resin production includes a mixing tank and a waste gas box. An air pump is fixedly connected to one side of the waste gas box.

[0015] As a further description of the above technical solution:

[0016] The mixing tank has a discharge port inside, and one side of scraper one and scraper two are in contact with the inner wall of the mixing tank.

[0017] As a further description of the above technical solution:

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, a motor drives a rotating column, which in turn drives the support frame and the activated carbon filter inside to rotate within the waste gas chamber. This allows the waste gas to come into full contact with the activated carbon filter and react fully with the filter medium. This solves the problem that when the waste gas passes through, it can only come into contact with a portion of the filter screen surface and cannot fully contact and react with the filter medium, resulting in poor treatment effect.

[0033] 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.

[0034] Reference Figures 1-3 This utility model provides an embodiment of a waste gas separation device for basic epoxy resin production, comprising a mixing tank 1 and a waste gas box 2. An air pump 3 is fixedly connected to one side of the waste gas box 2 to extract the waste gas generated in the mixing tank 1 and introduce it into the waste gas box 2 for treatment. The main task of the waste gas box 2 is to further purify the waste gas extracted from the mixing tank 1 through the extraction pipe 4. The input end of the air pump 3 is fixedly connected to the extraction pipe 4, which passes through the inside of the mixing tank 1. The output end of the air pump 3 is fixedly connected to the air delivery pipe 5, which passes through the inside of the waste gas box 2. A fan 8 is fixedly connected to one side of the waste gas box 2. The input end of the fan 8 is fixedly connected to the suction pipe 7, which passes through the inside of the waste gas box 2. The output end of the fan 8 is fixedly connected to the exhaust pipe 6. The fan 8 extracts the filtered air from the waste gas box 2 and discharges it into the external environment through the exhaust pipe 6. A filter assembly is provided inside the waste gas box 2, and a mixing assembly is provided inside the mixing tank 1.

[0035] The filtration assembly includes a rotating column 10, a support frame 11, and an activated carbon filter 12. The rotating column 10 is rotatably connected inside the exhaust gas chamber 2. One side of the support frame 11 is fixedly connected to one end of the rotating column 10. The activated carbon filter 12 is installed inside the support frame 11 and is used to adsorb harmful substances in the exhaust gas. A motor 9 is fixedly connected to the other side of the exhaust gas chamber 2. The output end of the motor 9 is connected to the rotating column 10. The rotating column 10 is driven to rotate by the motor 9. During the rotation, the activated carbon filter 12 inside the support frame 11 can continuously contact the exhaust gas and adsorb harmful substances and odors in the exhaust gas, ensuring that the exhaust gas is effectively purified.

[0036] Specifically, when using this epoxy resin production waste gas separation device, the epoxy resin raw material is first placed into the mixing tank 1 for uniform mixing. During this process, the air pump 3 is started, which drives the suction pipe 4 at the input end to quickly extract the waste gas generated inside the mixing tank 1. The waste gas is introduced into the waste gas box 2 for treatment by the action of the air pump 3. After the waste gas enters the waste gas box 2, the output end of the motor 9 drives the rotating column 10 to rotate. The rotating column 10 is connected to the support frame 11 at one end, causing the support frame 11 to rotate inside the waste gas box 2. An activated carbon filter 12 is installed inside the support frame 11. Under the rotation of the support frame 11, this filter continuously contacts the waste gas, exerting the adsorption effect of activated carbon to effectively remove impurities, odors and harmful substances in the waste gas. The treated air is then extracted through the suction pipe 7 and finally discharged into the external environment through the exhaust pipe 6, thereby achieving the separation and emission of waste gas.

[0037] Reference Figure 1 , Figure 4 and Figure 5 The mixing assembly includes a stirring rod 14 and a stirring blade 17. The stirring rod 14 is rotatably connected inside the mixing tank 1, and one side of the stirring blade 17 is fixedly connected to the outer wall of the stirring rod 14. The stirring rod 14 is driven to rotate by a motor 13, thereby driving the stirring blade 17 to quickly stir the mixture and ensure thorough mixing of the epoxy resin raw materials. The bottom of the mixing tank 1 is fixedly connected to the motor 13, and the output end of the motor 13 is connected to the stirring rod 14. A scraper 15 and a scraper 16 are fixedly connected to the outer wall of the stirring rod 14. A discharge port 18 is provided inside the mixing tank 1 to facilitate the discharge of the processed material after mixing. One side of both scraper 15 and scraper 16 is connected to the mixing tank 1. The inner walls are in contact, which can effectively clean the adhering substances on the inner wall of the mixing tank 1, prevent material residue, and thus improve the mixing efficiency. A feeding frame 19 is fixedly connected to the outer wall of the mixing tank 1. A sealing cover 21 is slidably connected inside the feeding frame 19. The sealing cover 21 fits into the discharge port 18. The sealing cover 21 ensures that no leakage occurs when the material is mixed by fitting into the discharge port 18. An electric push rod 20 is fixedly connected to one side of the feeding frame 19. The output end of the electric push rod 20 is connected to the sealing cover 21. A slide rail 22 is fixedly connected to the top of the feeding frame 19. A support rod 23 is fixedly connected to the top of the sealing cover 21. A pulley 24 is rotatably connected to the outer wall of the support rod 23. The pulley 24 is slidably connected inside the slide rail 22.

[0038] Specifically, during the mixing of epoxy resin, motor 13 drives the stirring rod 14 to rotate via its output end. Simultaneously, the stirring rod 14 is connected to scrapers 15 and 16 on the outer wall. During rotation, scrapers 15 and 16 rub and scrape against the inner wall of the mixing tank 1, ensuring uniform distribution of the epoxy resin raw materials within the mixing tank 1 and preventing localized accumulation and incomplete mixing. The scraper design not only ensures material uniformity but also reduces residue, ensuring ideal results with each mixing operation. After mixing, the mixture is conveyed by the electric push rod 20... The outlet drives the sealing cover 21 to slide, and the sealing cover 21 connects with the discharge port 18 of the feeding frame 19. During the sliding process, the sealing cover 21, through cooperation with the slide rail 22, drives the pulley 24 on the outer wall to slide along the slide rail 22, so that the sealing cover 21 can be smoothly disengaged from the discharge port 18 of the mixing tank 1. When the sealing cover 21 is disengaged, the rotation of scraper 15 and scraper 26 pushes the uniformly mixed epoxy resin out of the mixing tank 1 and into the feeding frame 19 for collection, ensuring smooth feeding and effective collection of epoxy resin, reducing material waste and improving production efficiency.

[0039] Working Principle: When using this epoxy resin production waste gas separation device, the epoxy resin is first placed into the mixing tank 1 for uniform mixing. During this process, the air pump 3 is started, which drives the suction pipe 4 at the input end to extract the waste gas generated inside the mixing tank 1. At the same time, the air supply pipe 5 sends the waste gas into the waste gas box 2. At this time, the output end of motor 9 drives the rotating column 10 to rotate, which drives the support frame 11 at one end to rotate, causing the activated carbon filter 12 inside the support frame 11 to rotate inside the waste gas box 2, thereby filtering and adsorbing impurities in the waste gas inside the waste gas box 2. Subsequently, the blower 8 drives the suction pipe 7 to extract the filtered gas inside the waste gas box 2 and discharge it through the exhaust pipe 6 at the output end of the blower 8, thereby achieving the effect of effectively separating and filtering the waste gas. When mixing the epoxy resin, the output end of motor 13... The stirring rod 14 and the scraper 15 on its outer wall rotate inside the mixing tank 1. At the same time, the stirring rod 14 also drives the scraper 15 and scraper 16 on the outer wall to rotate, so that the scraper 15 and scraper 16 scrape the inner wall of the mixing tank 1, thereby uniformly mixing the epoxy resin inside the mixing tank 1. After mixing, the sealing cover 21 can be slid inside the discharge frame 19 by the output end of the electric push rod 20. The sealing cover 21 drives the top slide rail 22 to move, and the slide rail 22 drives the pulley 24 on the outer wall to slide in the slide rail 22, thereby causing the sealing cover 21 to detach from the discharge port 18 inside the mixing tank 1. At this time, the rotation of the scraper 15 and scraper 16 pushes the mixed epoxy resin out of the mixing tank 1 and into the discharge frame 19 for collection, thereby achieving the effect of effectively mixing and discharging the epoxy resin.

[0040] 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.
