Description

Technical Field

[0001] This application relates to a power-free dust removal and purification device for air film silos. Background Art

[0002] An air film silo is a storage facility using an air-supported membrane structure. It combines new building materials and technologies, achieving a major technological innovation in the field of green grain storage. The design and construction of the air film silo are based on air film technology, which is a new building form emerging with the development of new materials and technologies. The air film silo has good heat insulation and airtight performance, and can achieve green grain storage, reducing the influx of external heat, maintaining the freshness and nutrition of grains. When the air film silo exchanges fresh air, a part of the gas needs to be discharged to maintain pressure balance; at this time, the air discharged by the air valve contains dust. If this dust is not treated, it will be directly discharged into the outdoor atmosphere, which does not meet the environmental protection requirements, and a dust removal and purification device is needed.

[0003] The existing patent with publication number CN220386146U discloses a power-free dust removal and purification device for air film silos, which relates to the technical field of dust removal and purification equipment. In this utility model, through the setting of a dust settling treatment chamber and dust removal nozzles, when the gas enters the dust settling treatment chamber, due to the increase in the cross-sectional area of the dust settling treatment chamber, the gas flow rate slows down, increasing the time for the turbid gas to pass through the dust settling treatment chamber. At the same time, the dust removal nozzles are opened, and the atomized water droplets sprayed by the dust removal nozzles are mixed with the dust in the air to form slurry. The slurry falls under its own gravity and converges and is discharged through the first sewage discharge pipe. After that, the air is further treated by the cyclone dust removal assembly and discharged from one end of the exhaust pipe, thus realizing the power-free dust removal and purification of the air film silo, without generating additional energy consumption, and having a low maintenance frequency, which is convenient for long-term use; through the setting of the cyclone dust removal assembly, the air is further purified, enhancing the purification effect of this power-free dust removal and purification device for air film silos.

[0004] In the existing dust removal and purification devices for air film silos, when the spray structure sprays air with dust, the air in the dust settling chamber directly flows and discharges towards the exhaust pipe side under the action of the air valve. The air flow rate is too fast, which will lead to incomplete spraying of the air, thereby reducing the dust removal effect. For example, in the above-mentioned dust removal and purification device, moreover, there are some harmful substances or odors in the discharged air, and direct discharge will also have an impact on the atmosphere.

[0005] Therefore, it is desired to provide a power-free dust removal and purification device for air film silos. Summary of the Utility Model

[0006] In this embodiment, a power-free dust removal and purification device for air film silos is provided, which solves the problems that too fast air flow rate will lead to incomplete spraying of the air, thereby reducing the dust removal effect, and that there are some harmful substances or odors in the discharged air, and direct discharge will also have an impact on the atmosphere.

[0007] According to one aspect of the present application, a gas film bin non-powered dust removal and purification device is provided, including a dust removal tank. One end of the dust removal tank is fixed with an air inlet pipe, and the other end of the dust removal tank is threadedly connected with an exhaust pipe. A water storage tank is fixed on the top of the dust removal tank, and a spraying structure is fixed at the bottom of the water storage tank. It is characterized in that the gas film bin non-powered dust removal and purification device further includes:

[0008] An activated carbon filter plate, which is threadedly connected inside the output end of the exhaust pipe;

[0009] A flow blocking structure, which is arranged inside the dust removal tank;

[0010] An arc-shaped filter screen and a scraper. The arc-shaped filter screen is fixed inside the input end of the exhaust pipe, and the scraper is arranged on one side of the arc-shaped filter screen close to the air inlet pipe.

[0011] Further, the spraying structure includes a water delivery pipe, a valve, a water distribution pipe and a spray head. The top of the water delivery pipe passes through the bottom of the water storage tank and is communicated with the inside of the water storage tank. An inlet is arranged on the top of the water storage tank, and a sealing plug is arranged on the inlet.

[0012] Further, a valve is fixed on the water delivery pipe. The bottom end of the water delivery pipe passes through the top of the dust removal tank and is fixed with a water distribution pipe. Multiple groups of spray heads are fixed at the bottom of the water distribution pipe.

[0013] Further, the flow blocking structure includes a corrugated plate, a connecting rod and a fixing rod. The corrugated plates are evenly distributed inside the dust removal tank. The two ends of adjacent corrugated plates inside the dust removal tank are connected by a connecting rod, and the two ends of the bottom of the corrugated plate are fixed with the inner bottom of the dust removal tank through a fixing rod.

[0014] Further, a rotating shaft is arranged at the center of the circle of the arc-shaped filter screen. The two ends of the rotating shaft are rotatably connected with the inner wall of the dust removal tank. Multiple groups of scrapers are fixed on the side wall of the rotating shaft, and the end of the scraper far away from the rotating shaft is slidably connected with the arc-shaped filter screen.

[0015] Further, a dust discharge pipe is fixed in the middle of the bottom of the dust removal tank, and support legs are fixed on both sides of the bottom of the dust removal tank on both sides of the dust discharge pipe.

[0016] The beneficial effects of the present application are as follows:

[0017] 1. By arranging a flow blocking structure inside the dust removal tank, multiple groups of corrugated plates in the flow blocking structure are evenly distributed inside the dust removal tank. When the air in the gas film bin flows into the dust removal tank through the air inlet pipe, it will pass through the corrugated plates. The corrugated plates are uneven, which can play a certain blocking role in the inflowing air, reduce the air flow speed, thereby enhancing the air spraying time, making the air spraying comprehensive, wetting the dust in the air, and improving the dust removal effect.

[0018] 2. By threadedly connecting an activated carbon filter plate to the output end of the exhaust pipe, the air after dust removal will pass through the activated carbon filter plate for filtration. The activated carbon can adsorb harmful substances and odors in the air, improve the purity of the discharged air, and prevent the discharged air from polluting the environment. The threaded connection between the activated carbon filter plate and the exhaust pipe facilitates the disassembly and replacement of the activated carbon filter plate.

[0019] 3. By fixing an arc-shaped filter net at the input end of the exhaust pipe, with a rotating shaft and a scraper arranged on one side of the arc-shaped filter net. During exhaust, the air flow will drive the rotation of the rotating shaft, thereby driving the rotation of the scraper. When the scraper rotates, it can block the particulate dust in the air flow to prevent the dust from flowing out. Moreover, one end of the scraper is slidably connected to the side wall of the arc-shaped filter net, and the rotation of the scraper can scrape off the impurities attached to the arc-shaped filter net.

[0033] A flow blocking structure 7, and the flow blocking structure 7 is arranged inside the dust removal tank 1;

[0034] A curved filter screen 8 and a scraper 10, the curved filter screen 8 is fixed inside the input end of the exhaust pipe 3, and the scraper 10 is arranged on one side of the curved filter screen 8 close to the intake pipe 2.

[0035] The spraying structure 6 includes a water delivery pipe 601, a valve 602, a water distribution pipe 603 and spray heads 604. The top of the water delivery pipe 601 passes through the bottom of the water storage tank 5 and is communicated with the inside of the water storage tank 5. An inlet 13 is arranged at the top of the water storage tank 5, and a sealing plug is arranged on the inlet 13.

[0036] A valve 602 is fixed on the water delivery pipe 601. The bottom end of the water delivery pipe 601 passes through the top of the dust removal tank 1 and is fixed with a water distribution pipe 603. Multiple groups of spray heads 604 are fixed at the bottom of the water distribution pipe 603.

[0037] The flow blocking structure 7 includes corrugated plates 701, connecting rods 702 and fixing rods 703. The corrugated plates 701 are evenly distributed inside the dust removal tank 1. The two ends of adjacent corrugated plates 701 inside the dust removal tank 1 are connected by connecting rods 702. The two ends of the bottom of the corrugated plates 701 are fixed to the inner bottom of the dust removal tank 1 through fixing rods 703.

[0038] A rotating shaft 9 is arranged at the center of the circle of the curved filter screen 8. The two ends of the rotating shaft 9 are rotatably connected to the inner wall of the dust removal tank 1. Multiple groups of scrapers 10 are fixed on the side wall of the rotating shaft 9.

[0040] Working principle: When the electrical components appearing in the application are in use, they are externally connected to a power supply and a control device. First, connect the dust removal and purification device to the exhaust fan on the air film bin. Fill an appropriate amount of water in the water storage tank 5 so that the air in the air film bin first passes through the dust removal and purification device and then is discharged. The air in the air film bin enters the dust removal tank 1 through the air inlet pipe. At this time, open the valve 602 so that the water in the water storage tank 5 is sprayed from the spray head 604 onto the incoming air through the water delivery pipe 601 and the water distribution pipe 603. When the air enters the dust removal tank 1, it will pass through the corrugated plate 701. The corrugated plate 701 is uneven, which will play a certain blocking role on the incoming air, reduce the air flow speed, thereby enhancing the air spraying time, making the air spraying comprehensive, wetting the dust in the air, improving the dust removal effect. The wetted dust will fall under the action of gravity and be discharged from the dust discharge pipe 11. When exhausting, the air flow will drive the rotating shaft 9 to rotate, thereby driving the scraper 10 to rotate. When the scraper 10 rotates, it can block the particulate dust in the air flow to prevent the dust from flowing out. Moreover, one end of the scraper 10 is slidably connected to the side wall of the arc-shaped filter screen 8. When the scraper 10 rotates, it can scrape off the impurities attached to the arc-shaped filter screen 8. The dust-removed air will be filtered and discharged through the activated carbon filter plate 4. The activated carbon can adsorb harmful substances and odors in the air, improve the purity of the discharged air, and make the discharged air not pollute the environment. The activated carbon filter plate 4 is threadedly connected to the exhaust pipe 3, which is convenient for disassembling and replacing the activated carbon filter plate 4. The exhaust pipe 3 is threadedly connected to the dust removal tank 1, which is convenient for disassembling the exhaust pipe 3, so as to facilitate the cleaning of the inside of the arc-shaped filter screen 8 and the dust removal tank 1.

For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
