Description
Technical Field
[0001] The utility model relates to the technical field of dust removal equipment, in particular to a dust removal device for a silo of a concrete mixing station. Background Art
[0002] Concrete is one of the most widely used materials in construction projects. It is made by mixing aggregates, cement, water, admixtures and additives in a certain proportion. In order to improve the strength of concrete, various raw materials must be mixed together in strict accordance with the proportions tested in advance. Therefore, concrete mixing plants are usually equipped with weighing silos for weighing raw materials.
[0003] The storage silo of the concrete mixing station generates a lot of dust during loading and operation. If the dust is directly discharged into the atmosphere, it will cause environmental pollution. Therefore, it needs to be dedusted before being discharged into the air. Traditional dust removal devices generally set filters to remove dust. During the long-term dust removal process, the surface of the filter is easily blocked by the grit contained in the dust. Although some filters will increase the shaking mechanism when setting, there is a certain amount of moisture in the space inside the silo, which makes the fine sand sticky. Dust is still easy to remain on the mesh of the filter, which will affect the dust removal work. Utility Model Content
[0004] In order to overcome the above-mentioned shortcomings, the utility model provides an anti-clogging concrete mixing station silo dust removal device.
[0005] The technical solution is: a concrete mixing station silo dust removal device, including a storage silo, a bottom plate, an ash inlet pipe, a dust removal silo, a filter, a fan, a speed reduction assembly and a cleaning assembly.

[0006] Furthermore, the deceleration assembly includes a protective cover, a driving rod, a rotating rod, a small gear, a large gear and a ring gear. A protective cover is fixed at a position below the fan in the dust removal bin, the protective cover is rotatably connected to the fan drive shaft, a small gear is connected to the bottom of the fan output shaft, a rotating rod is rotatably connected to the middle of the protective cover, three driving rods are evenly connected to the top of the rotating rod, large gears are fixed on the driving rods, the large gears are meshed with the small gears, a ring gear is fixed to the inner wall of the protective cover, the large gears are meshed with the ring gear, and the large gears and the small gears are both located inside the protective cover.
[0007] Furthermore, the rotation of the small gear will drive the large gear and the driving rod to rotate, and the driving rod will drive the rotating rod to rotate. The rotating rod can be decelerated by the ratio of the number of teeth of the large gear and the small gear.
[0008] Furthermore, the cleaning component includes a brush and a scraper. The positions of the rotating rod near the two filters are connected with brushes, and the brushes are in contact with the filters. Two scrapers are connected on both sides of the rotating rod, and the scrapers are in contact with the inner wall of the ash inlet bin.
[0009] Furthermore, the rotation of the rotating rod drives the brush and the scraper to rotate, the scraper cleans the inner wall of the dust removal bin, and the brush cleans the filter.

The brush and scraper can continuously clean the filter screen and the inner wall of the dust removal bin to avoid clogging of the filter screen.
[0013] 2. The nozzle can spray the water in the water tank into the dust removal bin, thereby reducing the dust and absorbing the fine sand in the dust so that the fine sand can be discharged through the discharge port. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0021] Embodiment 1: A dust removal device for a silo of a concrete mixing station, such as Figure 1-4 As shown, it includes a storage bin 1, a base plate 101, an ash inlet pipe 2, a dust removal bin 3, a filter screen 5, a fan 6, a chimney 7, a speed reduction assembly and a cleaning assembly. A storage bin 1 for storing concrete raw materials is fixed on the left side of the top of the base plate 101, and a dust removal bin 3 is fixed on the right side of the top of the base plate 101. The storage bin 1 and the dust removal bin 3 are connected by an ash inlet pipe 2. The filter screen 5 for filtering dust is symmetrically fixed inside the dust removal bin 3, and a fan 6 is installed on the upper part of the dust removal bin 3. A chimney 7 for blocking impurities is connected to the top of the dust removal bin 3. A speed reduction assembly is provided on the internal transmission shaft of the fan 6, and a cleaning assembly for cleaning the filter screen 5 and the inner wall of the ash inlet bin is provided on the speed reduction assembly. A discharge port 8 for discharging fine sand and debris is opened at the bottom of the dust removal bin 3.
[0022] like Figure 3 and Figure 4 As shown, the deceleration assembly includes a protective cover 9, a driving rod 10, a rotating rod 11, a pinion 14, a large gear 15 and a ring gear 16. A protective cover 9 is fixed at a position below the fan 6 in the dust removal bin 3. The protective cover 9 is rotatably connected to the drive shaft of the fan 6. A pinion 14 is connected to the bottom of the output shaft of the fan 6. The middle part of the protective cover 9 is rotatably connected to the rotating rod 11. Three driving rods 10 are evenly connected to the top of the rotating rod 11. Large gears 15 are fixed on the driving rods 10, and the large gears 15 are meshed with the pinion 14. A ring gear 16 is fixed on the inner wall of the protective cover 9, and the large gears 15 are meshed with the ring gear 16. The large gear 15 and the pinion 14 are both located inside the protective cover 9. The rotation of the pinion 14 will drive the large gear 15 and the driving rod 10 to rotate, and the large gear 15 will rotate along the ring gear 16. The driving rod 10 will drive the rotating rod 11 to rotate, and the rotating rod 11 can be decelerated by the ratio of the number of teeth of the large gear 15 to that of the pinion 14.
[0023] like Figure 3As shown, the cleaning component includes a brush 12 and a scraper 13. The brushes 12 are connected to the positions of the rotating rod 11 near the two filters 5, and the brushes 12 are in contact with the filter screens 5. The upper and lower sides of the rotating rod 11 are connected to two scrapers 13, and the scrapers 13 are in contact with the inner wall of the dust inlet bin. The rotation of the rotating rod 11 drives the brush 12 and the scraper 13 to rotate, and the scraper 13 cleans the inner wall of the dust removal bin 3, while the brush 12 cleans the filter screens 5.
[0024] When the concrete raw materials are transported to the mixing station, the storage bin 1 will be opened and the concrete will be stored in the storage bin 1. A lot of dust will be generated in the storage bin 1. When operating the dust removal, the fan 6 can be turned on to make the fan 6 suck the air in the dust removal bin 3 upwards. The dust in the storage bin 1 will enter the dust removal bin 3 through the ash inlet pipe 2, and then float upwards through the operation of the fan 6, and will be filtered and discharged through two filters 5. The chimney 7 can prevent external impurities from entering the dust removal bin 3 and can also play a role in rain protection. The filter 5 can filter out the fine sand contained in the dust, and the fine sand will fall downwards and be discharged from the discharge port 8. The rotation of the transmission shaft of the fan 6 will also drive the small gear 14 to rotate, and then drive the large gear 15 and the driving rod 10 to rotate. The large gear 15 will move along the ring gear 1 6 rotates, driving rod 10 to rotate and driving rotating rod 11 to rotate. Through the meshing of large gear 15 and small gear 14, the speed of rotating rod 11 can be made lower than the speed of rotation of the drive shaft of fan 6, so as to achieve the purpose of deceleration. The principle is to utilize the speed conversion of large gear 15 and small gear 14 to decelerate the number of revolutions of the drive shaft of fan 6 to the required number of revolutions and obtain a mechanism with a larger torque. The ratio of the number of teeth of large gear 15 and small gear 14 is the transmission force. The rotation of rotating rod 11 drives brush 12 and scraper 13 to rotate. Brush 12 can clean filter screen 5 to avoid clogging of filter screen 5, and scraper 13 can clean the inner wall of dust removal bin 3 and scrape off the dust on the inner wall. After completing the dust removal work of storage bin 1, fan 6 is turned off.
[0025] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 2 and Figure 5 As shown, it also includes a water inlet pipe 17, a water tank 18 and a nozzle 19. The water tank 18 is installed on the upper part of the dust removal bin 3, and a plurality of nozzles 19 are evenly installed on the inner side of the water tank 18. The front side of the upper part of the dust removal bin 3 is connected with the water inlet pipe 17, and the water inlet pipe 17 is connected with the water tank 18. A one-way valve is installed in the water inlet pipe 17. The water in the water tank 18 cannot flow out from the water inlet pipe 17 through the one-way valve, but water can be injected into the water tank 18 from the water inlet pipe 17 and the one-way valve.
[0026] When dust removal is being carried out in the storage bin 1, an external water pipe can be connected to the water inlet pipe 17 to inject water into the water tank 18 through the water inlet pipe 17. After the water injection is completed, the water pipe can be removed. When the fan 6 works to suck the dust in the storage bin 1 into the dust removal bin 3, the nozzle 19 can be opened to allow the nozzle 19 to spray the water in the water tank 18 into the ash inlet bin, where it comes into contact with the dust, and can absorb the fine sand in the dust, causing the fine sand to fall downward and be discharged, thereby achieving the purpose of dust reduction. When the dust removal is completed, the nozzle 19 can be closed.
[0027] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
