Description

Technical Field

[0001] This utility model relates to the field of high-frequency infrared carbon-sulfur analyzer technology, and more specifically, to a dust filtration device for a high-frequency infrared carbon-sulfur analyzer. Background Technology

[0002] The infrared carbon-sulfur analyzer, used in conjunction with a high-frequency induction combustion furnace, can quickly and accurately determine the mass fraction of carbon and sulfur in steel, iron, alloys, non-ferrous metals, cement, ore, glass, and other materials. It is a high-tech product integrating optics, mechanics, electronics, computer science, and analytical technology, featuring a wide measurement range and accurate and reliable analytical results.

[0003] A search revealed that utility model patent CN212855129U discloses a dust filtration device for a high-frequency infrared carbon-sulfur analyzer. The device includes a housing, a bearing seat inserted into the upper left side wall of the housing, an exhaust pipe installed inside the bearing seat, and a filter cylinder connected to the inner end of the exhaust pipe. The filter cylinder is located in the upper part of the inner cavity of the housing. A driven pulley and a drying box are sequentially arranged from the inside to the outside of the outer end of the exhaust pipe. This high-frequency infrared carbon-sulfur analyzer dust filtration device, through a series of structural designs and applications, avoids the need to filter dust particles using only a single HEPA filter, thus improving the filtration effect. Furthermore, the filter can be cleaned without disassembling it, saving time and effort, thereby enhancing the practicality of the high-frequency infrared carbon-sulfur analyzer dust filtration device. However, the above patents still have the following shortcomings: when rinsing the HEPA filter cylinder through the nozzle, dust and water will have a certain adhesive force after contact, making it difficult to ensure that the dust completely falls off the HEPA filter cylinder. In addition, when using the water-absorbing resin desiccant in the drying box to dry the filtered gas, the water-absorbing resin desiccant is generally in powder form, which is easy to mix into the gas, affecting the overall filtration effect. At the same time, the desiccant needs to be replaced frequently during continuous filtration, which is not very practical. Therefore, we have proposed a dust filtration device for a high-frequency infrared carbon and sulfur analyzer. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a dust filtration device for a high-frequency infrared carbon-sulfur analyzer.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A dust filtration device for a high-frequency infrared carbon-sulfur analyzer includes a housing with a rinsing mechanism. An air inlet pipe is fixedly sleeved on the side of the housing, and an exhaust pipe is rotatably connected to the side of the housing. One end of the exhaust pipe extends into the inner cavity of the housing and is fixedly connected to a filter screen. A dual-axis motor is fixedly mounted on the side of the housing. A first gear is fixedly sleeved on one output shaft of the dual-axis motor, and a second gear is fixedly sleeved on the outer side of the other end of the exhaust pipe. The second gear and the first gear mesh with each other. The other output shaft of the dual-axis motor extends into the inner cavity of the housing and is fixedly connected to a transmission rod. A rubber scraper is fixedly connected to the side of the transmission rod, and the top surface of one of the rubber scrapers contacts the bottom surface of the filter screen. A drying mechanism is provided on the side of the housing.

[0007] In a preferred embodiment of this utility model, the drying mechanism includes a support column fixedly connected to the side of the housing, a filter cylinder fixedly connected to the end of the support column, a drying chamber inside the filter cylinder, an air-drying chamber inside the filter cylinder, an air outlet pipe on the side of the filter cylinder, the end of the air outlet pipe communicating with the inner cavity of the drying chamber, a rotating groove in the middle of the filter cylinder, a servo motor fixedly mounted at the end of the filter cylinder, and a drive shaft fixedly connected to the output shaft of the servo motor. The part is movably sleeved into the inner cavity of the rotating groove and fixedly connected to a moisture-absorbing cotton board. The moisture-absorbing cotton board is located in the inner cavity of the drying chamber and the air-drying chamber. The side of the moisture-absorbing cotton board is in contact with the inner wall of the drying chamber and the air-drying chamber. The end of the exhaust pipe is rotatably connected to the inner cavity of the drying chamber. An electric heating tube is fixedly installed in the inner cavity of the air-drying chamber. A blower is fixedly sleeved at one end of the inner cavity of the air-drying chamber. A first filter screen is fixedly sleeved at the end of the blower. A ventilation groove is opened at the other end of the inner cavity of the air-drying chamber. A second filter screen is fixedly sleeved in the inner cavity of the ventilation groove.

[0008] As a preferred embodiment of this utility model, the rinsing mechanism includes a water pump fixedly installed on the side of the housing. Both ends of the water pump are fixedly connected to water pumping steel pipes. One end of the water pumping steel pipe is fixedly sleeved to the bottom of the inner cavity of the housing, and the other end of the water pumping steel pipe is fixedly sleeved to the inner cavity of the housing and fixedly connected to a water distribution box. The bottom surface of the water distribution box is provided with multiple nozzles, and the nozzles are located directly above the filter screen cylinder.

[0009] As a preferred embodiment of this utility model, a plurality of filter media plates are sleeved on the lower part of the inner cavity of the housing, and a sealing door is opened on the side of the housing and on the side of the filter media plates.

[0010] As a preferred embodiment of this utility model, a controller is fixedly installed on the side of the housing.

[0011] As a preferred embodiment of this utility model, a drain valve is fixedly installed on the bottom of the side of the housing, and the end of the drain valve extends to the bottom of the inner cavity of the housing.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] (1) In this utility model, when the water sprayed from the nozzle washes the dust on the filter screen, the dual-axis motor drives the transmission rod and rubber scraper to rotate, and the rubber scraper scrapes the bottom of the filter screen to clean the dust attached to the filter screen. This avoids the problem that the dust will have a certain adhesion after contacting the water, and the dust will not fall off the filter screen. This improves the practicality of the dust filtration device of the high-frequency infrared carbon and sulfur analyzer.

[0014] (2) In this utility model, when the gas is discharged from the exhaust pipe, the moisture-absorbing cotton plate in the drying chamber is used to absorb and eliminate the moisture in the gas. In addition, the servo motor drives the moisture-absorbing cotton plate to rotate, so that the moisture-absorbing cotton plate gradually rotates to the inner cavity of the drying chamber. The moisture-absorbing cotton plate in the drying chamber rotates to the inner cavity of the drying chamber, thereby fully absorbing the moisture of the gas flowing in the drying chamber. At the same time, the electric heating tube is energized to generate heat. The external gas is filled into the inner cavity of the drying chamber by the fan. The electric heating tube heats the air, and the heated air dries the damp moisture-absorbing cotton plate in the drying chamber, ensuring that the moisture-absorbing cotton plate continuously absorbs moisture from the gas, thus improving the practicality of the dust filtration device of the high-frequency infrared carbon-sulfur analyzer.

[0029] For details, please refer to Figure 1 and Figure 2The rinsing mechanism 2 includes a water pump 26 fixedly installed on the side of the housing 1.

[0035] In this embodiment, wastewater at the bottom of the inner cavity of the housing 1 is discharged through the drain valve 33.

[0036] Working Principle: During operation, the gas to be filtered is first introduced into the inner cavity of the housing 1 through the inlet pipe 11. Simultaneously, the water pump 26 is activated to draw water from the bottom of the inner cavity of the housing 1 into the water distribution box 28. The water in the water distribution box 28 is then sprayed downwards from the nozzle 29, using the downward-spraying water to treat the dust in the gas. The treated gas then passes through the filter cylinder 4 and enters the interior of the filter cylinder 4 for further filtration. The filtered gas then enters the drying chamber 14 through the exhaust pipe 3. Next, the dual-shaft motor 5 is activated, driving the first gear 6 to rotate. The meshing transmission between the first gear 6 and the second gear 7 drives the exhaust pipe 3 and the filter cylinder 4 to rotate, causing the nozzle 29 to spray water at different positions on the filter cylinder 4 to wash away the dust on the outside of the filter cylinder 4. Additionally, the dual-shaft motor 5 drives the transmission rod 8 and the rubber scraper 9 to rotate, using the rubber scraper 9 to remove dust from the sides of the filter cylinder 4. The dust is scraped off to ensure it falls off smoothly. The fallen dust is caught by the filter plate 30, which separates the dust and water. Then, the gas entering the drying chamber 14 is moistened by the moisture-absorbing cotton plate 20, and the moistened gas is discharged from the air outlet 21. Finally, the servo motor 18 is started to drive the drive shaft 19 and the moisture-absorbing cotton plate 20 to rotate, so that the moisture-absorbing cotton plate 20 gradually rotates into the inner cavity of the drying chamber 15. The moisture-absorbing cotton plate 20 in the drying chamber 15 rotates into the inner cavity of the drying chamber 14, thereby fully absorbing moisture from the gas flowing in the inner cavity of the drying chamber 14. At the same time, the electric heating tube 16 is energized to generate heat, and the fan 22 is started to fill the inner cavity of the drying chamber 15 with external air. The electric heating tube 16 heats the air, and the heated air dries the moist moisture-absorbing cotton plate 20 in the inner cavity of the drying chamber 15. The water vapor generated during drying is discharged from the ventilation groove 24.
