Abstract
Description
Technical Field
[0001] This invention relates to the field of chemical equipment technology, and in particular to a chemical equipment exhaust gas filtration device. Background Technology
[0002] Chemical waste gas specifically refers to toxic and harmful gaseous pollutants emitted by chemical enterprises during various chemical production, processing, storage, and transportation processes. This type of waste gas is typically complex in composition, containing a wide variety of pollutants with significantly different physical and chemical properties and varying degrees of toxicity. It is often accompanied by foul odors, corrosiveness, and flammability and explosiveness. Its uncontrolled emission not only causes air pollution and disrupts the ecological balance, but can also enter the human body through respiration and skin contact, damaging the respiratory, cardiovascular, and even nervous systems, seriously threatening public health and ecological safety.
[0003] According to application number 202010524440.2, a waste gas filtration device for chemical equipment is disclosed, relating to the field of chemical equipment technology. The invention includes a purification tank; a waste gas inlet hood is fixedly connected to the top surface of the purification tank; an electric louver assembly is installed on the inner wall of the waste gas inlet hood; a dust collection hopper is fixedly connected to the bottom surface of the purification tank; a high-pressure cleaning air inlet hood and an exhaust hood are respectively connected to both sides of the purification tank; a main exhaust pipe is fixedly connected to the top surface of the exhaust hood; a drive motor is fixedly connected to one surface of the exhaust hood; a filter mechanism is rotatably connected to the inner wall of the purification tank via bearings; one end of the output shaft of the drive motor is fixedly connected to the filter mechanism. This invention, through the design of the filter mechanism, transforms the traditional plate-type static filter plate of the filtration device into a rotatable cylindrical filter plate. By changing the filter plate structure and the rotatable design of the filter cylinder, the filter cylinder can perform purification operations uniformly and wear out evenly.
[0004] The above solution still has some shortcomings in actual use; although the cleaning air inlet pipe can clean the impurities inside the filter cartridge, the chemical processing will produce pollutants such as incompletely polymerized viscous resin droplets and oil mist. These impurities can easily penetrate the filter holes and enter the filter cartridge. It is difficult to effectively remove the viscous resin droplets and oil mist by relying solely on the subsequent supporting equipment, which will significantly reduce the cleaning effect and thus affect the overall operating efficiency and practicality of the device. Summary of the Invention

Detailed Implementation
[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0021] It will be understood by those skilled in the art that, unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless defined as herein.
[0022] Example 1: Reference Figure 1-8 A chemical equipment exhaust gas filtration device includes a purification cylinder 1, a connector 2 installed on the upper surface of the purification cylinder 1, and an installation hole opened on the outer surface of the connector 2. This structural design facilitates precise docking and reliable connection with other pipelines, effectively ensuring the sealing and unobstructed flow of the chemical exhaust gas transport path, thereby ensuring that the subsequent chemical exhaust gas filtration treatment process can be carried out stably and efficiently.
[0023] The filter assembly 3 is installed inside the connector 2. The filter assembly 3 includes a purification mechanism 31 for purifying impurities. The purification mechanism 31 includes a partition 301 and a circular plate 302 fixedly connected inside the purification cylinder 1, and a motor 303 installed on the outer surface of the purification cylinder 1. The partition 301 and the circular plate 302 cooperate with each other to effectively seal the internal space of the purification cylinder 1, which can effectively prevent the bypass, leakage or short circuit of the exhaust gas, thereby ensuring that the exhaust gas can flow through the filtration area according to the preset path, ensuring the stable operation of the subsequent filtration process, and significantly improving the overall purification effect and treatment efficiency.
[0024] An extension rod 304 is fixedly connected to the output end of the motor 303. The outer surface of the extension rod 304 is rotatably connected to the outer surfaces of the partition plate 301 and the circular plate 302. The extension rod 304, the partition plate 301, and the circular plate 302 adopt a rotatable connection structure, which can provide stable support for the extension rod 304 during operation, effectively reducing radial sway and eccentric offset, thereby ensuring that the extension rod 304 maintains good concentricity and operational stability during rotation. A cleaning roller 310 is fixedly installed on the outer surface of the extension rod 304. The cleaning roller 310 itself has good scraping and cleaning capabilities; together with the continuous and stable rotational power provided by the motor 303, it can drive the cleaning roller 310 to rotate at a uniform speed, achieving efficient cleaning of the surface of the filter components, thereby significantly improving the cleaning efficiency and the long-term stable operation of the overall purification device.
[0025] The outer surface of the extension rod 304 is fixedly connected to a meshing gear 305, and the outer surface of the circular plate 302 is rotatably connected to a set of air supply pipes 306. The outer surface of each air supply pipe 306 is fixedly connected to a rotating gear 307, and the rotating gear 307 meshes with the outer surface of the meshing gear 305. Through the precise meshing transmission between the meshing gear 305 and the rotating gear 307, the air supply pipe 306 can be smoothly driven to achieve circumferential rotation, so that the air supply and cleaning operations can be synchronized and the angle can be flexibly adjusted, thereby providing good working conditions for the subsequent cleaning of the filter element and cylinder wall, and effectively improving the convenience and coverage of the cleaning operation.
[0026] Each gas delivery pipe 306 is connected to a filter roller 308 at the other end, and the outer surface of the filter roller 308 is in contact with the outer surface of the cleaning roller 310. The filter roller 308 can effectively adsorb impurities and dirt in the exhaust gas, realizing the preliminary filtration and purification treatment of chemical exhaust gas. At the same time, the outer surface of the filter roller 308 is uniformly provided with round holes, which does not affect the normal filtration efficiency, but increases the contact area between the cleaning medium and the filter element, providing convenience for subsequent cleaning operations such as rinsing and scraping, facilitating the rapid removal of attached pollutants, improving the cleaning effect and the sustainable use performance of the device.
[0027] Each filter roller 308 has a set of guide rods 309 fixedly connected to its outer surface, and the other end of the guide rods 309 is slidably connected to the outer surface of the partition plate 301, which realizes the support of the filter roller 308 and thus ensures the rotation effect of the filter roller 308 during use.
[0028] Example 2: Reference Figure 1 and Figure 8A chemical equipment exhaust gas filtration device is basically the same as in Embodiment 1, but further, the cleaning mechanism 32 includes a hose 321 connected to one end of each air supply pipe 306. The connection between the hose 321 and the purification cylinder 1 is equipped with a bearing. Through the rotational support of the bearing, the hose 321 and the rotating component can form a relatively independent motion relationship, effectively avoiding problems such as displacement, twisting or coiling of the hose due to the continuous rotation of the filter roller 308, ensuring stable and reliable air supply, and ensuring continuous and smooth cleaning operation. The other end of the hose 321 is connected to a quick connector 322. Through the quick connector 322, quick docking and sealed installation with the air pump equipment can be achieved, effectively improving disassembly and assembly efficiency and ease of use. During the cleaning operation, the high-pressure gas output by the air pump is smoothly introduced through the quick connector, which can powerfully blow and thoroughly remove the dust and impurities remaining inside the filter roller 308, thereby efficiently completing the cleaning work of the inner and outer surfaces of the filter roller 308 and ensuring the continuous and stable filtration performance of the filter roller.
[0029] Each filter roller 308 has a screw 323 threadedly connected inside, and the screw 323 is rotatably connected to the outer surface of the partition plate 301. Each screw 323 has a scraper 324 threadedly connected to its outer surface. Driven by the rotation of the screw 323, the scraper 324 can achieve a smooth linear displacement, allowing the scraper to precisely conform to the inner wall of the filter roller 308 and effectively scrape away and clean the grease and viscous contaminants attached to it. At the same time, an anti-sticking agent is coated on the arc surface of the filter roller 308, which can significantly reduce the adhesion of grease and dirt; while a lubricant is coated on its thick end face, which can effectively reduce the frictional resistance when the scraper 324 moves, and prevent the scraper from deviating, jamming or abnormally moving during the rotation of the filter roller 308, thereby ensuring that the scraper always maintains a stable working posture and ensuring the continuous and reliable operation of subsequent scraping and cleaning operations.
[0030] Each scraper 324 has a set of arc-shaped holes 325 on its outer surface. An arc-shaped plate 326 is slidably connected inside each arc-shaped hole 325. The arc-shaped plate 326 is installed inside the filter roller 308. Through the cooperation between the arc-shaped plate 326 and the arc-shaped hole 325, the movement of the scraper 324 can be guided. At the same time, the arc-shaped plate 326 can prevent impurities from falling onto the surface of the screw 323, thereby ensuring the thread effect between the screw 323 and the scraper 324 and ensuring that the scraper 324 can move normally.
[0031] A set of drive wheels 327 are fixedly connected to the outer surface of the extension rod 304. The other end of each screw 323 is fixedly connected to a driven wheel 328. The drive wheel 327 and the driven wheel 328 are connected by a belt 329. Power is provided by the motor 303. With the stable transmission between the drive wheel 327 and the driven wheel 328, the screw 323 can be driven to rotate smoothly, thereby driving the scraper 324 to achieve directional displacement and efficiently scraping and cleaning the grease and viscous impurities attached to the inner wall of the filter roller 308.
[0032] A receiving box 4 is installed on the outer surface of the purification cylinder 1, and an output pipe 5 is connected to the outer surface of the purification cylinder 1. The receiving box 4 can collect the impurities after cleaning, which is convenient for subsequent centralized processing by staff and indirectly saves some of the frequency of manual labor. At the same time, the output pipe 5 can discharge the purified waste gas. In addition, a one-way valve is installed inside the output pipe 5 to prevent unfiltered waste gas from escaping during the processing, thereby ensuring the personal safety of the staff.
[0033] Each filter roller 308 has a discharge hole 320 on its outer surface, which can discharge oily impurities and facilitate subsequent cleaning.
[0034] Working principle: First, the exhaust gas is introduced into the purification cylinder 1 by connecting to an external pipe via connector 2. Then, the motor 303 is started, and its output end drives the extension rod 304 to rotate, which in turn drives the meshing gear 305 to rotate synchronously. Through the meshing transmission between the meshing gear 305 and the rotating gear 307, the cleaning roller 310 and the filter roller 308 rotate synchronously. During the rotation of the filter roller 308, it adsorbs and purifies impurities in the exhaust gas, while the cleaning roller 310 simultaneously cleans the dust and impurities adhering to the surface of the filter roller 308.
[0035] After initial cleaning, connect one end of quick connector 322 to the air pump to blow away impurities inside filter roller 308. Then, drive the drive wheel 327 to rotate via motor 303. The drive wheel 327 and driven wheel 328 work together to rotate the screw 323, which in turn moves the scraper 324 to remove grease-containing impurities from inside filter roller 308. The cleaned grease is discharged through the discharge hole 320 into the collection box 4 for subsequent centralized processing. Finally, open the solenoid valve to discharge the purified waste gas through the output pipe 5.
[0036] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
