Description

Technical Field

[0001] This utility model relates to the field of bag filter technology, and in particular to a stable feeding structure for bag filters. Background Technology

[0002] A baghouse dust collector is a dry dust filtration device that uses filter bags made of fibrous fabric to filter dust-laden gas. As the gas passes through, the dust is trapped on the surface of the filter bag, achieving gas-solid separation. When the filter bag accumulates dust to a certain extent, the dust is removed by a dust removal device. In order to improve the uniformity of material feeding, a stable material feeding structure is required for the baghouse dust collector.

[0003] The stable discharge structure of a bag filter dust collector refers to the design that ensures the stable discharge of dust from the hopper. It includes a reasonable hopper shape to facilitate dust falling, a suitable ash discharge device such as a screw conveyor to control the ash discharge flow, and an airlock device to prevent backflow of external air, thus maintaining the stability and efficiency of the discharge process.

[0004] Currently, the material feeding stability structure of baghouse dust collectors on the market uses a conveying pipe to connect the discharged material to external equipment for reprocessing. In order to improve the feeding stability, the existing technology uses an auger to convey the material. However, in actual use, due to the instability of the material during feeding, the amount of material conveyed by the auger is sometimes more and sometimes less, making it difficult to ensure that the amount of material conveyed by the auger is uniform, thus reducing the stability of the device. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a material stabilization structure for baghouse dust collectors, aiming to improve the problem that the material stabilization structure in the prior art causes uneven feeding in the subsequent feeding process due to the unstable amount of material being fed.

The upper connecting plate is fixedly connected to the hollow tube. A hollow plate is connected to the inner side of the connecting plate.

The top of the telescopic tube passes through the lower connecting plate and is fixedly connected to a rotating rod. Hollow plates are fixedly connected to the upper and lower sides of the rotating rod. A hollow plate is fixedly connected to the top of the lower connecting plate. A positioning mechanism is provided on the outer side of the hollow tube. The positioning mechanism is used to cool the material.

[0008] The positioning mechanism includes a ventilation hood connected to the left side of the hollow cylinder. Filter screens are connected to both the upper and lower sides of the left end of the hollow cylinder. A motor is fixedly connected to the top of the ventilation hood. The output end of the motor passes through the ventilation hood and is fixedly connected to a rotating column. A first bevel gear is fixedly connected to both the upper and lower outer sides of the rotating column. A second bevel gear is rotatably connected to both the upper and lower inner sides of the ventilation hood. The second bevel gear meshes with the first bevel gear. Fan blades are fixedly connected to the outer side of the second bevel gear.

[0009] As a further description of the above technical solution:

[0010] The hollow cylinder is fixedly connected to the front and rear sides of the exterior with fixing plates, and the fixing plates are fixedly connected to the left and right sides of the interior with support columns.

[0012] A movable door is provided at the top of the feed inlet, and a hinge is fixedly connected to the outside of the movable door. The movable door is rotatably connected to the feed inlet through the hinge.

[0013] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, material enters the hollow cylinder through the feed inlet. The motor is started, and the rotating wheel is driven by the belt drive. The left rotating wheel drives the rotating rod and the hollow disc to rotate. The holes and the hollow plate intersect and stagger, so that the material gradually reaches the bottom of the cylinder.

The rotation of the fan blade draws external air into the ventilation hood, and the airflow flows through the filter screen. After being filtered by the filter screen, the airflow enters the hollow cylinder, which can cool the material inside the cylinder and prevent the material from overflowing, thereby improving the convenience of the device.

Detailed Implementation

[0031] 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.

[0032] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a bag filter dust collector with a stable feeding structure, comprising a hollow cylinder 1 and a belt 5. A feed inlet 24 is provided on the top left side of the hollow cylinder 1. A motor 3 is fixedly connected to the bottom right side of the hollow cylinder 1. Rotating wheels 4 are rotatably connected to the left and right sides of the bottom of the hollow cylinder 1, and the two rotating wheels 4 are connected by a belt 5. The output end of the motor 3 passes through the hollow cylinder 1 and is fixedly connected to the left rotating wheel 4. An auger 9 is fixedly connected to the top of the left rotating wheel 4. A hollow tube 8 is connected to the right side of the inside of the hollow cylinder 1, and connecting discs 12 are provided on the upper and lower sides of the outside of the hollow tube 8. The lower connecting plate 12 is slidably connected to the hollow tube 8. Spring rods 6 are fixedly connected to the bottom of the lower connecting plate 12 around its perimeter. The upper connecting plate 12 is fixedly connected to the hollow tube 8. A hollow plate 13 is connected to the inner side of the connecting plate 12. A telescopic tube 7 is fixedly connected to the top of the left rotating wheel 4. The top of the telescopic tube 7 passes through the lower connecting plate 12 and is fixedly connected to a rotating rod 10. Hollow plates 11 are fixedly connected to the upper and lower sides of the outer side of the rotating rod 10. A hollow plate 25 is fixedly connected to the top of the lower connecting plate 12. A positioning mechanism 2 is provided on the outer side of the hollow cylinder 1. The positioning mechanism 2 is used to cool the material.

[0033] Specifically, the material enters the hollow cylinder 1 through the feed inlet 24. After the motor 3 is started, the rotating wheels 4 on both sides rotate synchronously under the drive of the belt 5. The left rotating wheel 4 drives the rotating rod 10 and the connecting plate 12 to rotate. By using the intersection and stagger of the holes of the connecting plate 12 and the holes of the hollow plate 13, the material is gradually sent to the bottom of the hollow cylinder 1 for storage. As the material increases, the weight increases and compresses the spring rod 6. The lower connecting plate 12 moves down along the hollow tube 8, and the hollow plate 25 moves accordingly to expose the bottom of the hollow tube 8. At this time, the right rotating wheel 4 rotates and drives the telescopic tube 7 and the auger 9 to rotate. The telescopic tube 7 does not affect the movement of the connecting plate 12, and the auger 9 achieves stable feeding.

[0034] Reference Figure 1 , Figure 2 and Figure 5 The positioning mechanism 2 includes a ventilation hood 201, which is connected to the left side of the hollow cylinder 1. Filter screens 207 are connected to both the upper and lower sides of the left end of the hollow cylinder 1. Filter screens 207 can prevent material overflow. A motor 202 is fixedly connected to the top of the ventilation hood 201. The output end of the motor 202 passes through the ventilation hood 201 and is fixedly connected to a rotating column 203. Starting the motor 202 can drive the rotating column 203 to rotate. A bevel gear 1 204 is fixedly connected to both the upper and lower sides of the outer side of the rotating column 203. When the rotating column 203 rotates, it can drive the bevel gear 1 204 to rotate. A bevel gear 205 is rotatably connected to both the upper and lower sides of the inner side of the ventilation hood 201. The bevel gear 205 meshes with the bevel gear 1 204. The rotation of the bevel gear 1 204 can drive the bevel gear 205 to rotate. A fan blade 206 is fixedly connected to the outer side of the bevel gear 205. When the bevel gear 205 rotates, it can drive the fan blade 206 to rotate.

[0035] Specifically, after starting the motor 202, it will drive the rotating column 203 to start rotating. As the rotating column 203 rotates, the bevel gear 204 installed on it will also rotate synchronously, thereby driving the bevel gear 205 that meshes with it to rotate. When the bevel gear 205 rotates, it will drive the fan blade 206 to rotate at high speed. When the fan blade 206 rotates, it will attract external airflow into the ventilation hood 201. The airflow flows in the ventilation hood 201 and is then sent to the filter screen 207, so that the filter screen 207 will filter the airflow. The filtered clean airflow can flow into the hollow cylinder 1 to cool the material in the hollow cylinder 1, and at the same time, it can effectively prevent the material from overflowing.

[0036] Reference Figure 1 , Figure 2 and Figure 5The hollow cylinder 1 is fixedly connected to the front and rear sides of the exterior with fixed plates 15, and the interior left and right sides of the fixed plates 15 are fixedly connected to support columns 16. The top of the feed inlet 24 is provided with a movable door 19, and the outside of the movable door 19 is fixedly connected with a hinge 20. The movable door 19 is rotatably connected to the feed inlet 24 through the hinge 20. The movable door 19 can be opened and closed through the hinge 20 to facilitate feeding into the feed inlet 24. The hollow cylinder 1 is provided with handles 21 on all four sides of the exterior. The upper and lower sides of the handles 21 are threaded with screws 22. The handles 21 are threaded to the hollow cylinder 1 through the screws 22. The handles 21 facilitate the handling of the device, and the handles 21 can be removed when not needed by removing the screws 22 to prevent them from affecting the operation.

[0037] Specifically, the support column 16 can support and position the device via the fixing plate 15, the hinge 20 can open and close the movable door 19, and prevent dust from entering the feed inlet 24 when the device is not in use. The handle 21 installed by the holding screw 22 makes it easy to hold and move the device.

[0038] Reference Figure 1 , Figure 2 and Figure 5 A positioning frame 17 is connected to the middle of the front side of the hollow cylinder 1. An observation window 18 is fixedly connected to the inner side of the positioning frame 17, allowing observation of the operation inside the hollow cylinder 1. A controller 23 is fixedly connected to the right side of the hollow cylinder 1. The controller 23 is electrically connected to the motor 3 and the motor 202, respectively, and can control the switching and starting of the motor 3 and the motor 202. A bracket 14 is fixedly connected to the bottom of the ventilation hood 201. The outer side of the bracket 14 is fixedly connected to the hollow cylinder 1, and the bracket 14 can improve the structural stability of the ventilation hood 201 and the hollow cylinder 1.

[0039] Specifically, by observing the observation window 18 inside the positioning frame 17, it is easy to observe the internal operation of the device. By operating the controller 23, the starting and running power between the motor 3 and the motor 202 can be controlled respectively. By using the bracket 14, the structural strength and stability between the hollow cylinder 1 and the ventilation hood 201 can be improved.

[0040] Working principle: Before using the device, the material is fed into the hollow cylinder 1 through the feed port 24. At this time, the motor 3 is started and the rotating wheel 4 is driven to rotate through the belt 5. When the left rotating wheel 4 rotates, it drives the rotating rod 10 and the connecting plate 12 to rotate. When the connecting plate 12 rotates, the holes on it intersect and cross with the hollow plate 13, so that the material is gradually fed into the bottom of the hollow cylinder 1 for storage. As more material is stored, the weight will squeeze the spring rod 6 to compress and cause the lower connecting plate 12 to move down along the hollow tube 8. At this time, the hollow plate 25 will move accordingly to expose the bottom of the hollow tube 8. When the right rotating wheel 4 rotates, it will drive the telescopic tube 7 and the auger 9 to rotate. The telescopic tube 7 can move without affecting the movement of the connecting plate 12, and the rotation of the auger 9 can transport the material to feed it stably.

[0041] Furthermore, starting the motor 202 can drive the rotating column 203 to rotate. At this time, as the rotating column 203 rotates, the bevel gear 204 on it rotates, thereby driving the bevel gear 205 meshing with it to rotate. The rotation of the bevel gear 205 can drive the fan blade 206 to rotate. When the fan blade 206 rotates, it will drive the external airflow into the ventilation hood 201, and send the airflow into the filter screen 207. The filter screen 207 can allow the airflow to flow into the hollow cylinder 1 after filtration, cool the material inside, and prevent the material from overflowing.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
