Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment equipment in the preparation of organic cobalt salts, specifically to waste gas treatment equipment with self-cleaning function. Background Technology

[0002] RTO (Regenerative Thermal Oxidizer) waste gas treatment systems are widely used in chemical, pharmaceutical, coating, printing, food, adhesive products, petrochemical, electronics manufacturing, and automobile manufacturing industries. RTO is particularly suitable for treating large volumes of low-concentration organic waste gas, and can adapt to emissions with large concentration fluctuations while achieving high-efficiency purification.

[0003] Patent (CN220558804U) discloses an RTO (Regenerative Thermal Oxidizer) waste gas treatment device, relating to the field of waste gas treatment technology. It includes a waste gas treatment box and a waste gas purification box. An inlet pipe is fixed to the left side of the waste gas treatment box, and an exhaust pipe is fixed to the right side. The waste gas purification box is fixed inside the waste gas treatment box near the exhaust pipe. It also includes a filter assembly. The filter assembly includes a support plate and a filter section. The support plate is fixed inside the waste gas treatment box on the side away from the waste gas purification box. A rectangular groove is formed in the support plate, and a roller is movably connected within the rectangular groove. The filter section is fixed outside the roller, and when waste gas enters the waste gas treatment box, it can drive the filter section to rotate. The rectangular groove is located at the bottom of the support plate, and its area occupies two-thirds of the area of ​​the support plate. This accelerates the flow of waste gas entering the waste gas treatment box, avoids the concentration of impurities in the waste gas, and improves the efficiency of waste gas filtration.

[0004] Although the RTO exhaust gas treatment equipment in the aforementioned patent is equipped with a filter assembly to filter the exhaust gas, the rotating filter assembly causes the impurities in the exhaust gas to be too dispersed inside the pipe, making it difficult to clean and collect the impurities, which seriously affects the subsequent exhaust gas filtration effect. Summary of the Invention

[0005] The purpose of this invention is to provide a waste gas treatment device with self-cleaning function in the preparation process of organic cobalt salts, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a waste gas treatment device with self-cleaning function, including an air inlet filter cylinder and an air inlet pipe. An air inlet is provided on one side of the top of the inner wall of the air inlet filter cylinder, and an air outlet is provided on the other side of the inner wall of the air inlet filter cylinder. A filter screen is provided on the inner wall of the air inlet filter cylinder outside the air outlet. The air inlet pipe is located outside the air outlet. A scraping and cleaning component is provided inside the air inlet filter cylinder and rotatedly connected. A collection chamber is provided at the bottom of the air inlet filter cylinder, and several material discharge ports are provided between the air inlet filter cylinder and the collection chamber.

[0007] Furthermore, the air intake pipe is equipped with rotating fan blades, and the support shaft of the fan blades extends to the top of the air intake pipe and is connected to the scraping and cleaning assembly via a transmission belt assembly.

[0008] Furthermore, the scraping cleaning assembly includes a vertically arranged scraper and a rotating shaft. The rotating shaft is rotatably connected to the top of the inner wall of the air intake filter cylinder. The top of the rotating shaft extends to the top of the air intake filter cylinder and is connected to the transmission belt assembly. The rotating shaft is fixedly connected to the scraper through several support rods.

[0009] Furthermore, a guide strip is horizontally provided at the bottom of the scraper, and the length of the guide strip is greater than half of the inner diameter of the air inlet filter cylinder.

[0010] Furthermore, the filter screen has a fan-shaped structure, and two support rods are provided, with the ends of the two support rods away from the rotation axis respectively fixedly connected to the top and bottom of the scraper plate.

[0011] Furthermore, the top of the collection bin is provided with a guide pipe at an angle to the bottom of the discharge port, and the guide pipes at the bottom of two adjacent discharge ports are symmetrically arranged.

[0012] Furthermore, the bottom of the collection chamber is provided with a movably connected bottom cover, one end of which is hinged to the collection chamber, and the other end of which is connected to the collection chamber by a latch.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] 1. This utility model, by setting up an air intake filter cylinder, an air intake pipe, an air inlet, an air delivery port, a filter screen, a scraping and cleaning component, a collection bin, and a discharge port, allows waste gas to be sent into the air intake filter cylinder through the air inlet. After passing through the filter screen, the waste gas is transported from the air delivery port to the air intake pipe. The waste gas entering the air intake pipe undergoes filtration treatment and is then sent to the RTO waste gas treatment system for subsequent purification treatment through the air intake pipe. The scraping and cleaning component rotates inside the air intake filter cylinder, effectively cleaning the impurities filtered on the surface of the filter screen and scraping them off the filter screen. At the same time, the scraping and cleaning component rotates and sweeps the fallen impurities, effectively sending them from the discharge port into the collection bin. This completes the cleaning and collection of impurities on the surface of the filter screen, allowing for the separate collection and storage of impurities filtered in the waste gas. This effectively prevents impurities filtered in the waste gas from dispersing inside the air intake filter cylinder, thereby ensuring the effectiveness of subsequent waste gas filtration and purification treatment.

[0015] 2. In this utility model, the fan blades are installed inside the air intake pipe. When the exhaust gas enters the air intake pipe after filtration, the exhaust gas impacts the fan blades, effectively driving them to rotate. The fan blades can drive the scraping and cleaning component to rotate via the transmission belt assembly, eliminating the need for a separate rotation drive component for the scraping and cleaning component, thus effectively saving energy. When the fan blades drive the scraping and cleaning component to rotate via the transmission belt assembly, the rotating shaft rotates, and the rotating shaft drives the scraper plate to rotate via the support rod. The scraper plate rotates around the rotating shaft, scraping and cleaning the impurities on the surface of the filter screen during the rotation. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1-4This utility model provides a technical solution: a waste gas treatment device with self-cleaning function, including an air inlet filter cylinder 1 and an air inlet pipe 2. An air inlet 3 is provided on one side of the top of the inner wall of the air inlet filter cylinder 1, and an air outlet 4 is provided on the other side of the inner wall of the air inlet filter cylinder 1. A filter screen 5 is provided on the inner wall of the air inlet filter cylinder 1 outside the air outlet 4. The air inlet pipe 2 is located outside the air outlet 4. A rotatably connected scraping and cleaning assembly 6 is provided inside the air inlet filter cylinder 1. A collection chamber 7 is provided at the bottom of the air inlet filter cylinder 1, and several material drop ports 8 are provided between the air inlet filter cylinder 1 and the collection chamber 7. A rotating fan blade 20 is provided inside the air inlet pipe 2. 1. The support shaft of the fan blade 201 extends above the air intake pipe 2 and is connected to the scraping and cleaning assembly 6 via the transmission belt assembly 9. The scraping and cleaning assembly 6 includes a vertically arranged scraper 601 and a rotating shaft 602. The rotating shaft 602 is rotatably connected to the top of the inner wall of the air intake filter cylinder 1. The top of the rotating shaft 602 extends above the air intake filter cylinder 1 and is connected to the transmission belt assembly 9. The rotating shaft 602 is fixedly connected to the scraper 601 via several support rods 603. A guide strip 604 is horizontally provided at the bottom of the scraper 601. The length of the guide strip 604 is greater than half of the inner diameter of the air intake filter cylinder 1.

[0024] In one embodiment, the filter screen 5 has a fan-shaped structure. The fan-shaped structure of the filter screen 5 facilitates the covering and filtration of the entire air outlet 4, ensuring the filtration effect of the exhaust gas. At the same time, it facilitates the cleaning of the filter screen 5 by the rotating scraper cleaning component 6. Two support rods 603 are provided. The ends of the two support rods 603 away from the rotation axis 602 are respectively fixedly connected to the top and bottom of the scraper plate 601. The shape of the support rods 603 is designed to effectively ensure the support effect of the scraper plate 601, while avoiding excessive support rods 603 from causing excessive adhering of impurities in the exhaust gas to the surface of the support rods 603.

[0025] In one embodiment, a guide pipe 701 is inclinedly provided at the top of the collection bin 7 and at the bottom of the discharge port 8. The guide pipes 701 at the bottom of two adjacent discharge ports 8 are symmetrically arranged. The guide pipes 701 guide the discharge port 8 to ensure that the scraped and cleaned impurities quickly enter the collection bin 7. At the same time, the guide pipes guide the exhaust gas entering the collection bin 7 to prevent the exhaust gas from blowing the impurities inside the collection bin 7 upward and to prevent the impurities inside the collection bin 7 from returning to the air inlet filter cartridge 1 from the discharge port 8.

[0026] In one embodiment, the bottom of the collection chamber 7 is provided with a movably connected bottom cover 702. One end of the bottom cover 702 is hinged to the collection chamber 7, and the other end of the bottom cover 702 is connected to the collection chamber 7 by a latch. The bottom cover 702 is sealed at the bottom of the collection chamber 7 to ensure that impurities inside the collection chamber 7 leak out. When it is necessary to clean the impurities inside the collection chamber 7, the latch is opened to open the bottom cover 702, and then the impurities inside the collection chamber 7 can be cleaned and removed.

[0027] The working principle of this utility model:

[0028] Refer to the instruction manual appendix Figures 1-4 This utility model, by setting up an air intake filter cylinder 1, an air intake pipe 2, an air inlet 3, an air outlet 4, a filter screen 5, a scraper cleaning component 6, a collection bin 7, and a discharge port 8, allows waste gas to be sent into the air intake filter cylinder 1 through the air inlet 3. After passing through the filter screen 5, the waste gas is transported from the air outlet 4 to the air intake pipe 2. The waste gas entering the air intake pipe 2 undergoes filtration treatment and is then sent to the RTO waste gas treatment system for subsequent purification treatment through the air intake pipe 2. The scraper cleaning component 6 rotates inside the air intake filter cylinder 1. The rotating motion effectively cleans the impurities filtered on the surface of the filter screen 5, scrapes the impurities off the filter screen 5, and simultaneously the material hanging and cleaning component 6 can rotate and sweep the fallen impurities, effectively sending the impurities from the discharge port 8 into the collection chamber 7, completing the cleaning and collection of impurities on the surface of the filter screen 5, and collecting and storing the impurities filtered in the exhaust gas separately, which can effectively prevent the impurities filtered in the exhaust gas from being dispersed inside the air intake filter cartridge 1, thereby ensuring the effect of subsequent exhaust gas filtration and purification treatment;

[0029] The fan blade 201 is installed inside the air intake pipe 2. When the exhaust gas enters the air intake pipe 2 after being filtered, the exhaust gas impacts the fan blade 201, which can effectively drive the fan blade 201 to rotate. The fan blade 201 can drive the scraping and cleaning component 6 to rotate through the transmission belt assembly 9. There is no need to equip the scraping and cleaning component 6 with a separate rotation drive component, which can effectively save energy.

[0030] When the fan blade 201 drives the scraping and cleaning assembly 6 to rotate via the transmission belt assembly 9, the rotating shaft 602 rotates. The rotating shaft 602 drives the scraper 601 to rotate via the support rod 603. The scraper 601 rotates around the rotating shaft 602. During the rotation, the scraper 601 scrapes and cleans the impurities on the surface of the filter screen 5.

[0031] When the scraper plate 601 moves in a circular motion, the guide bar 604 rotates and guides the material at the bottom of the air intake filter cylinder 1 in a horizontal direction. As the guide bar 604 rotates at the bottom of the air intake filter cylinder 1, it pushes and guides the impurities scraped off the filter screen 5, allowing the impurities to quickly enter the collection chamber 7 from the discharge port 8 for collection. The length of the guide bar 604 is designed to be greater than half the inner diameter of the air intake filter cylinder 1, ensuring that the guide bar 604 can effectively increase the material coverage of the bottom of the air intake filter cylinder during rotation, thereby improving the material collection and treatment effect of impurities.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
