Description

Technical Field

[0001] This utility model is a rectifier device for waste gas treatment equipment, belonging to the technical field of waste gas treatment equipment. Background Technology

[0002] Waste gas treatment equipment is widely used in industries such as chemical, pharmaceutical, and printing. It is primarily used to remove harmful substances from waste gases, such as volatile organic compounds (VOCs), particulate matter, and other pollutants. Its core function is to purify waste gases using physical or chemical methods to meet emission standards. Existing waste gas treatment equipment typically includes the following components: Inlet: Guides the waste gas to be treated into the treatment system. Treatment unit: Includes filters, adsorbents, catalysts, etc., used to remove pollutants from the waste gas. Outlet: Discharges the treated clean gas. Fan: Provides power to ensure the waste gas flows smoothly through the entire system.

[0003] However, as filters are used for a long time, their filtration efficiency will deteriorate, so they need to be disassembled and cleaned. This process significantly affects the efficiency of exhaust gas treatment. There is an urgent need for a rectifier device for exhaust gas treatment equipment to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a rectifier for waste gas treatment equipment to solve the problems mentioned in the background. This utility model designs a flow adjustment structure that can quickly adjust the waste gas flow direction to another filter for filtration when a filter needs to be disassembled and cleaned after long-term use, without affecting the waste gas treatment efficiency, and at the same time, facilitates the disassembly and cleaning of filters that have been used for a long time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rectifier for waste gas treatment equipment, comprising an adjusting circular shell, a sealing cover, a first square treatment cylinder, a second square treatment cylinder, and a filter body. The upper end of the adjusting circular shell is sealed with a sealing cover via a sealing rubber ring. A sealing bearing is embedded in the center of the adjusting circular shell, and a rotating rod is longitudinally mounted on the upper end of the sealing bearing. A hollow plate is longitudinally fixed to the left rear side of the rotating rod, a first baffle is longitudinally fixed to the right rear side of the rotating rod, and a second baffle is longitudinally fixed to the front end of the rotating rod. A screw rod is longitudinally mounted on the upper center of the sealing cover via the sealing bearing, and the lower end of the screw rod is connected to the rotating rod. A first square processing cylinder and a second square processing cylinder are respectively installed on the front and rear sides of the right end of the sealing cover. The first square processing cylinder and the second square processing cylinder have installation slots on their opposite outer sides, and a rubber frame and multiple magnetic positioning pins are fixed at each of the two installation slots. A snap-fit ​​cover is longitudinally attached to the outer side of each of the two rubber frames. There are two filter bodies. The two filter bodies are respectively fixed to the opposite inner sides of the two snap-fit ​​covers, and the two filter bodies are completely snapped into the first square processing cylinder and the second square processing cylinder through the installation slots. A pre-filter, a HEPA high-efficiency filter and an activated carbon filter are longitudinally snapped into each of the two filter bodies from left to right.

[0006] Furthermore, an air intake pipe is installed through the left end of the adjusting shell.

[0007] Furthermore, the rear side of the first baffle and the front side of the second baffle both slide against the inner wall of the adjusting shell.

[0008] Furthermore, each of the two snap-fit ​​covers is embedded with a magnetic ring around its perimeter, and multiple magnetic positioning pins are respectively inserted into multiple magnetic rings by magnetic attraction. Each of the two snap-fit ​​covers has a pull handle fixed to its opposite outer side.

[0009] Furthermore, an exhaust pipe is connected to both the exhaust end of the first square processing cylinder and the exhaust end of the second square processing cylinder.

[0010] Furthermore, transparent glass plates are embedded on both the front and rear sides of the upper end of the sealing cover.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a rectifier device for waste gas treatment equipment. Because it incorporates an adjusting cylindrical shell, a rotating rod, a hollow plate, a first baffle, a second baffle, a screw rod, a sealing cover, a first square treatment cylinder, a magnetic positioning pin, a snap-fit ​​cover, a magnetic ring, and a second square treatment cylinder, our design improvements and practical use have shown that this device has a reasonable structure and good practicality. The design of a flow adjustment structure allows for the rapid adjustment of the waste gas flow direction to another filter for filtration when a filter in one location needs to be disassembled and cleaned after prolonged use, without affecting the waste gas treatment efficiency. It also facilitates the disassembly and cleaning of filters used for extended periods. Attached Figure Description

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3This utility model provides a technical solution: a rectifier device for waste gas treatment equipment, including an adjusting circular shell 1, a sealing cover 9, a first square treatment cylinder 11, a second square treatment cylinder 21, and a filter body 17. The upper end of the adjusting circular shell 1 is sealed and fixed with the sealing cover 9 by a sealing rubber ring 3. A sealing bearing is embedded in the middle of the adjusting circular shell 1, and a rotating rod 4 is longitudinally installed on the upper end of the sealing bearing. A hollow plate 5 is longitudinally fixed on the left rear side of the rotating rod 4, a first baffle 6 is longitudinally fixed on the right rear side of the rotating rod 4, and a second baffle 7 is longitudinally fixed on the front end of the rotating rod 4. A screw rod 8 is longitudinally installed on the middle of the upper end of the sealing cover 9 through the sealing bearing, and the lower end of the screw rod 8 is connected to the rotating rod 4. The first square treatment cylinder 11 and the second square treatment cylinder 21 are respectively installed on the front and rear sides of the right end of the sealing cover 9. The square treatment cylinder 21 has mounting slots on its outer sides, and a rubber frame 12 and multiple magnetic positioning pins 13 are fixed at each of the two mounting slots. A snap-fit ​​cover 14 is longitudinally attached to the outer side of each of the two rubber frames 12. Two filter bodies 17 are provided, each fixed to the inner side of one of the two snap-fit ​​covers 14. The two filter bodies 17 are fully inserted into the first square treatment cylinder 11 and the second square treatment cylinder 21 through the mounting slots. A pre-filter 18, a HEPA high-efficiency filter 19, and an activated carbon filter 20 are longitudinally installed inside each of the two filter bodies 17 from left to right. This design solves the problem that in existing waste gas treatment equipment, the filtration effect of filters deteriorates over time, requiring disassembly and cleaning, which negatively impacts waste gas treatment efficiency.

[0019] As the first embodiment of this utility model: an air inlet pipe 2 is installed through the left end of the regulating cylindrical shell 1, which facilitates the introduction of external exhaust gas into the regulating cylindrical shell 1. The rear side of the first baffle 6 and the front side of the second baffle 7 slide against the inner wall of the regulating cylindrical shell 1. The added first baffle 6 and second baffle 7 can intercept the gas entering the regulating cylindrical shell 1, so that the exhaust gas in the regulating cylindrical shell 1 will only be transmitted to the second square processing cylinder 21 through the hollow plate 5.

[0020] Both snap-fit ​​covers 14 are surrounded by embedded magnetic rings 15. Multiple magnetic positioning pins 13 are inserted into the magnetic rings 15 by magnetic attraction. Pull handles 16 are fixed to the outer sides of both snap-fit ​​covers 14. The addition of multiple magnetic positioning pins 13 ensures that the two snap-fit ​​covers 14 will not detach when longitudinally fitted to the outer sides of the two rubber frames 12. Exhaust pipes are installed connecting the exhaust ends of the first square treatment cylinder 11 and the second square treatment cylinder 21, facilitating the discharge of treated waste gas from either the first square treatment cylinder 11 or the second square treatment cylinder 21. Transparent glass plates 10 are embedded on the front and rear sides of the upper end of the sealing cover 9, allowing for easy observation of the positions of the first baffle 6 and the second baffle 7.

[0021] As a second embodiment of this utility model: In actual use, exhaust gas enters the regulating cylindrical shell 1 through the intake pipe 2. Because the rear side of the first baffle 6 and the front side of the second baffle 7 slide against the inner wall of the regulating cylindrical shell 1, the exhaust gas in the regulating cylindrical shell 1 will only be transmitted to the second square treatment cylinder 21 through the hollow plate 5. Then, after multiple filtrations by the filter body 17 (in this process, the primary filter 18 acts as the first line of defense, mainly used to capture larger particles, such as dust and hair, protecting the subsequent more precise filtration system from the influence of large particulate pollutants; the HEPA high-efficiency filter 19 removes fine particles; and the activated carbon filter 20 adsorbs VOCs in the exhaust gas), it is finally discharged to the outside through the exhaust pipe. When the main body 17 needs to be disassembled after long-term use, first turn the screw rod 8. The screw rod 8 drives the rotating rod 4, hollow plate 5, first baffle 6 and second baffle 7 to rotate, so that the first baffle 6 and second baffle 7 block the air inlet end of the second square treatment cylinder 21. After the first square treatment cylinder 11 is connected to the air inlet pipe 2 through the hollow plate 5, the filter body 17 in the first square treatment cylinder 11 can treat the exhaust gas. Then, the external personnel pull the pull handle 16 at the rear position, and the multiple magnetic positioning pins 13 and multiple magnetic rings 15 separate until the rear filter body 17 is pulled out from the second square treatment cylinder 21. Then the cleaning operation can be carried out, and the exhaust gas treatment operation will not be affected during this process.
