Description

Technical Field

[0001] This utility model application relates to the technical field of baghouse dust collectors, specifically a pulse baghouse dust collector with automatic ash unloading function. Background Technology

[0002] Baghouse dust collectors are a type of high-efficiency dry dust collection equipment. Their core working principle is to use filter bags made of fiber materials to capture solid particles in dust-laden gas through filtration. When dusty gas enters the dust collector, the particles are trapped on the outer surface of the filter bags, and the purified gas is discharged through the filter bags. As the dust layer thickens, the system periodically cleans the dust through pulse jet cleaning and other methods to maintain a stable filtration efficiency. This equipment features high dust removal efficiency, strong adaptability, and reliable operation, and is widely used in flue gas purification and dust recovery in industries such as power, metallurgy, and building materials.

[0003] Currently, during the ash discharge process of traditional baghouse dust collectors, dust often clumps due to moisture or electrostatic forces. The clumps of dust tend to stick and accumulate inside the ash discharge port, gradually forming stubborn blockages. This problem not only seriously hinders the normal ash discharge from the ash hopper and affects the continuous and stable operation of the system, but also aggravates internal wear of the equipment, leading to a decrease in ash cleaning efficiency. Frequent shutdowns for manual cleaning are required, increasing maintenance costs and operating burden. Summary of the Invention

[0004] To address the problem of dust agglomerating due to moisture or electrostatic forces, and the resulting stubborn blockages that tend to accumulate inside the ash discharge port, this invention provides a pulse bag filter with an automatic ash discharge function to solve the aforementioned issues.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An automatic ash discharge pulse bag dust collector includes a dust collector body, an air inlet on one side of the dust collector body, an exhaust port on the other side of the dust collector body, a dust collector bag body fixed inside the dust collector body, a pulse cleaning device body inside the dust collector bag body, an ash discharge port at the bottom of the dust collector body, a stirring wheel rotatably installed inside the ash discharge port, a servo motor fixed on the outside of the dust collector body, the output end of the servo motor fixedly connected to the middle of the stirring wheel, and an ash storage box fixedly connected below the ash discharge port.

[0006] Furthermore, a number of water spray nozzles are fixed on the top surface inside the ash storage box, and a water supply pipe is fixed on the top surface outside the ash storage box, with each water spray nozzle connected to the water supply pipe.

[0007] Further, connecting blocks are fixed on both sides of one end of the bottom of the ash storage box, a sealing bottom plate is provided at the bottom end of the ash storage box, one end of the sealing bottom plate is rotatably connected with the two connecting blocks, an air cylinder is fixed on a side of the ash storage box away from the connecting blocks, a limit rod is fixed at an output end of the air cylinder, and one end of the limit rod is disposed below the sealing bottom plate.

[0008] Further, the limit rod is L-shaped, and the length of the bottom end of the limit rod is greater than the maximum stroke of the air cylinder.

[0009] Further, the water spray nozzles are disposed around the lower part of the ash discharge port, and the distance between every two adjacent water spray nozzles is the same.

[0010] Further, the stirring wheel is in a m-shape, the length and width of the stirring wheel are the same as those of the ash discharge port, and rounded corners are provided on all outer edges of the stirring wheel.

[0011] Compared with the prior art, the beneficial effects of the utility model are: 1. In the present utility model, the stirring wheel is arranged inside the ash discharge port, and is driven to rotate by a servo motor, so that the stirring wheel breaks up ash accumulated at the ash discharge port, and blocks the ash discharge port through the stirring wheel, so that workers can freely control the ash discharge time. Meanwhile, the servo motor drives the stirring wheel to rotate, so that the stirring wheel drives ash to be discharged, and the rotation speed of the stirring wheel is adjusted through the servo motor, so that the ash discharge speed of the dust collector main body can be adjusted, which solves the problem that ash is caked due to moisture of dust or electrostatic effect, caked ash blocks are easy to adhere and accumulate inside the ash discharge port, and gradually form stubborn blockage.

[0012] 2. In the present utility model, the ash storage box is arranged below the ash discharge port, and the air cylinder controls the lifting of the limit rod, so that the limit rod drives the sealing bottom plate to open and close, so that the ash inside the ash storage box can be automatically discharged. Meanwhile, for the ash inside the ash storage box, there is no need to worry about caking, instead, the dust raising problem during ash recycling needs to be considered. At this time, water is input into the water spray nozzles through a water delivery pipe, so that the water spray nozzles spray a small amount of water mist, and water droplets combine with ash and naturally fall on the top surface of the sealing bottom plate, which reduces the problem of dust raising caused by excessively dry ash inside the ash storage box when the sealing bottom plate is opened.

Detailed Description of Embodiments

[0016] In order to make the application purpose, features and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the embodiments described below are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0017] With reference to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a pulse bag filter with automatic ash discharging function includes a dust collector main body 1, an air inlet 2 is opened on one side of the dust collector main body 1, an air outlet 3 is opened on the other side of the dust collector main body 1, a dust removal bag main body 4 is fixed inside the dust collector main body 1, a pulse ash cleaning device main body 5 is arranged inside the dust removal bag main body 4, an ash discharge outlet 6 is opened at the bottom end of the dust collector main body 1, a stirring wheel 7 is rotatably arranged inside the ash discharge outlet 6, a servo motor 8 is fixed outside the dust collector main body 1, the output end of the servo motor 8 is fixedly connected with the middle part of the stirring wheel 7, an ash storage box 9 is communicated and fixed below the ash discharge outlet 6, and the stirring wheel 7 breaks up the dust inside the dust collector main body 1.

[0018] Specifically, the shape of the stirring wheel 7 is a "rice" shape, the length and width of the stirring wheel 7 are the same as the length and width of the ash discharge outlet 6, the outer edges of the stirring wheel 7 are all provided with rounded corners, and the stirring wheel 7 can seal the ash discharge outlet 6.

[0019] As an optimization solution, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, several water spray nozzles 10 are fixed on the top surface inside the ash storage box 9, and a water supply pipe 11 is fixed on the top surface outside the ash storage box 9. Each water spray nozzle 10 is connected to the water supply pipe 11. The water spray nozzles 10 are located around the bottom of the ash discharge port 6. The distance between any two adjacent water spray nozzles 10 is the same. The water spray nozzles 10 reduce the dust situation inside the ash storage box 9.

[0020] Specifically, connecting blocks 15 are fixed on both sides of one end of the bottom of the ash storage box 9. A sealing base plate 12 is provided at the bottom of the ash storage box 9. One end of the sealing base plate 12 is rotatably connected to the two connecting blocks 15. A cylinder 13 is fixed on the side of the ash storage box 9 away from the connecting blocks 15. A limit rod 14 is fixed at the output end of the cylinder 13. One end of the limit rod 14 is located below the sealing base plate 12. The limit rod 14 is L-shaped. The length of the bottom end of the limit rod 14 is greater than the maximum stroke of the cylinder 13 to prevent the sealing base plate 12 from coming off the limit rod 14.

[0021] Working principle: Air carrying dust is introduced into the dust collector body 1 through the air inlet 2. At this time, the dust passes through the dust collector bag body 4 and is discharged through the exhaust port 3. The dust in the air is filtered and blocked by the dust collector bag body 4. When there is a lot of dust on the dust collector bag body 4, the pulse cleaning device body 5 is activated, which sends a pulse airflow to the dust collector bag body 4. At this time, the dust on the dust collector bag body 4 is shaken off by the airflow. The dust accumulates at the ash discharge port 6. The servo motor 8 is activated, which drives the stirring wheel 7 to rotate. At this time, the stirring wheel 7 breaks up the dust clumps in the dust. At the same time, the rotating stirring wheel 7 carries the dust stuck on the stirring wheel 7 down to the ash discharge port 6 and falls into the ash storage box. Inside the ash storage box 9, by stopping the stirring wheel 7, the stirring wheel 7 can block the ash discharge port 6. When dust falls into the ash storage box 9, water is introduced into the spray nozzle 10 through the water supply pipe 11, and the water is atomized and sprayed out through the spray nozzle 10, so that the dust inside the ash storage box 9 combines with water droplets, reducing the dust inside the ash storage box 9. When the dust inside the ash storage box 9 needs to be discharged, the cylinder 13 is started, so that the cylinder 13 drives the limit rod 14 to move downward. At this time, the sealing bottom plate 12 opens under the action of gravity, and the dust inside the ash storage box 9 can be discharged. The cylinder 13 is reset, so that the limit rod 14 moves upward, and drives one end of the sealing bottom plate 12 to move upward, so that the sealing bottom plate 12 and the ash storage box 9 are closed.
