Description

Technical Field

[0001] This utility model relates to the field of coal powder processing technology, specifically to a coal powder silo for coal powder processing and collection. Background Technology

[0002] Coal pulverization is the process of crushing and grinding coal into fine particles (coal powder) through specific processes. It aims to improve the combustion efficiency of coal, meet the needs of different industries, and achieve efficient utilization of resources. In the coal pulverization process, the coal powder silo is an important piece of equipment for collecting and storing coal powder. The coal powder silo is a core facility of thermal power plants and blast furnace injection systems, undertaking the functions of coal powder storage and transfer. In the prior art, patent CN217806496U discloses a coal powder silo for coal powder processing and collection, including a storage silo, a mixing tank and a buffer plate. The inner wall of the storage silo is fixedly connected to a connecting rod, one end of the connecting rod is fixedly connected to a fixed seat, the top of the fixed seat is provided with a support plate, and both sides of the support plate are provided with buffer plates through hinge seats, and the buffer plates are located above the connecting rod. The top of the fixed seat is symmetrically provided with return springs, and the two sets of return springs are respectively located on both sides of the support plate. There are some problems with this type of coal powder silo used for coal powder processing and collection. For example, the coal powder falling between adjacent mixing blades is caused by the rotation of the mixing blades alone. This method lacks interference with the coal powder adsorbed on the discharge pipe and the inner wall of the coal powder silo, which affects the discharge effect of this part of the coal powder and the overall discharge effect of the coal powder silo. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a coal powder silo for coal powder processing and collection. The silo uses an impeller to actively convey coal powder while a hammer periodically strikes the discharge pipe, causing the silo to vibrate and improving the discharge efficiency of coal powder. This can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a coal powder silo for coal powder processing and collection, comprising a coal powder tank, a discharge pipe at the lower end of the coal powder tank, a feed pipe at the upper end of the coal powder tank, and a striking mechanism; The striking mechanism includes an annular chamber, a rotating shaft, striking handles, and a rotating ring. The annular chamber is fixedly connected to the upper end of the outer surface of the discharge pipe. The upper end of the annular chamber is rotatably connected to evenly distributed rotating shafts. Each rotating shaft has a striking handle fixedly connected to its upper end. A striking hammer is fixedly connected to the end of the striking handle away from the central axis of the adjacent rotating shaft. The striking hammers are all installed in conjunction with the side wall of the discharge pipe. Gears are fixedly connected to the lower end of each rotating shaft. A rotating ring is slidably connected to the middle of the outer arc surface of the annular chamber. An internal gear ring is fixedly connected to the middle of the inner arc surface of the rotating ring. All three gears are meshed with the internal gear ring. The impeller rotation realizes the active conveying of pulverized coal, while the striking hammers realize the periodic striking of the discharge pipe, causing the pulverized coal chamber to vibrate and improving the discharge efficiency of pulverized coal.

[0005] Furthermore, the striking mechanism also includes a drive handle, a connecting column, a rotating handle, and a drive shaft. The drive handle is fixedly connected to the left end of the outer arc surface of the rotating ring. A sliding groove is provided inside the drive handle. A motor frame is fixedly connected to the left end of the lower surface of the annular chamber. The drive shaft is rotatably connected to the left end of the motor frame. A rotating handle is fixedly connected to the upper end of the drive shaft. A connecting column is fixedly connected to the upper end of the rotating handle. The outer surface of the connecting column is slidably connected to the interior of the adjacent sliding groove, thereby realizing the periodic reciprocating rotation of the rotating ring and thus realizing the periodic oscillation of the striking hammer.

[0006] Furthermore, a control box is installed on the front side of the pulverized coal tank, and a controller is installed inside the control box. The input terminal of the controller is electrically connected to an external power source to control various electrical appliances.

[0007] Furthermore, the striking mechanism also includes a motor, which is located on the left end of the lower surface of the motor frame. The upper end of the output shaft of the motor is fixedly connected to the lower end of the drive shaft, and the input end of the motor is electrically connected to the output end of the controller to provide driving force for the periodic oscillation of the striking hammer.

[0008] Furthermore, a conveying pipe is provided in the middle of the discharge pipe, and a rotating shaft is rotatably connected inside the conveying pipe. Evenly distributed impellers are fixedly connected to the outer surface of the rotating shaft. A second motor is provided at the front end of the conveying pipe. The rear end of the output shaft of the second motor is fixedly connected to the front end of the rotating shaft. The input end of the second motor is electrically connected to the output end of the controller to realize the active discharge of pulverized coal.

[0009] Furthermore, an electric valve is provided at the lower end of the discharge pipe, and the input end of the electric valve is electrically connected to the output end of the controller to control the opening and closing of the discharge pipe.

[0010] Furthermore, the outer arc surface of the pulverized coal tank is fixedly connected with uniformly distributed annular reinforcing ribs, and the uppermost annular reinforcing rib and the lowermost annular reinforcing rib are fixedly connected with uniformly distributed vertical reinforcing ribs to improve the supporting strength of the pulverized coal tank.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This coal powder silo for coal powder processing and collection has the following advantages: The motor drives a crank-connecting rod mechanism to achieve periodic reciprocating rotation of the rotating ring, which in turn achieves periodic reciprocating rotation of the striking hammer through a planetary gear mechanism. This results in periodic striking of the discharge pipe, causing vibration of the discharge pipe and effectively reducing the degree of coal powder adsorption on the discharge pipe and the inner wall of the coal powder tank. While the impeller rotation achieves active coal powder conveying, the striking hammer periodically strikes the discharge pipe, causing vibration of the coal powder silo and improving the coal powder discharge efficiency.

[0014] 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.

[0015] Please see Figure 1-5This embodiment provides a technical solution: a coal powder silo for coal powder processing and collection, including a coal powder tank 1, a discharge pipe 2 at the lower end of the coal powder tank 1, and a feed pipe 11 at the upper end of the coal powder tank 1. Coal powder is added into the coal powder tank 1 through the feed pipe 11, and the coal powder accumulates and is stored inside the coal powder tank 1. A control box 14 is provided on the front side of the coal powder tank 1, and a controller 15 is provided inside the control box 14. The input terminal of the controller 15 is electrically connected to an external power supply, and a knocking mechanism 3 is also included. The striking mechanism 3 includes an annular chamber 31, a rotating shaft 32, a striking handle 33, and a rotating ring 34. The annular chamber 31 is fixedly connected to the upper end of the outer surface of the discharge pipe 2. The upper end of the annular chamber 31 is rotatably connected to evenly distributed rotating shafts 32. Each rotating shaft 32 has a striking handle 33 fixedly connected to its upper end. A striking hammer 4 is fixedly connected to the end of the striking handle 33 away from the central axis of the adjacent rotating shaft 32. The striking hammers 4 are all installed in cooperation with the side wall of the discharge pipe 2. Gears are fixedly connected to the lower end of each rotating shaft 32. The rotating ring 34 is slidably connected to the middle of the outer arc surface of the annular chamber 31. An internal gear ring is fixedly connected to the middle of the inner arc surface of the rotating ring 34. All three gears are meshed with the internal gear ring. (The internal gear ring and the three gears are all located inside the annular chamber 31, and the outer arc surface of the rotating ring 34 is...) Both the upper and lower ends of the ring 31 are fixedly connected with sealing ribs. Both the upper and lower ends of the outer arc surface of the ring 31 are provided with rib grooves. The sealing ribs are tightly slidably connected to the adjacent rib grooves, thus ensuring the sealing of the connection between the rotating ring 34 and the ring 31, preventing external impurities from entering the interior of the ring 31 and affecting the transmission effect of the planetary gear mechanism. The striking mechanism 3 also includes a drive handle 35, a connecting column 36, a rotating handle 37, and a drive shaft 38. The drive handle 35 is fixedly connected to the left end of the outer arc surface of the rotating ring 34. A sliding groove is provided inside the drive handle 35. A motor frame 5 is fixedly connected to the left end of the lower surface of the ring 31. The drive shaft 38 is rotatably connected to the left end of the motor frame 5. The rotating handle 37 is fixedly connected to the upper end of the drive shaft 38. A [missing information - likely a component or component] is fixedly connected to the upper end of the rotating handle 37. The connecting post 36 has its outer surface slidably connected to the interior of the adjacent slide groove. The striking mechanism 3 also includes a motor 39, which is located at the left end of the lower surface of the motor frame 5. The upper end of the output shaft of the motor 39 is fixedly connected to the lower end of the drive shaft 38. The input end of the motor 39 is electrically connected to the output end of the controller 15. The controller 15 enables the motor 39 to operate. The rotation of the output shaft of the motor 39 drives the drive shaft 38 to rotate, which in turn drives the rotating handle 37 to rotate, thereby causing the connecting post 36 to rotate around the central axis of the drive shaft 38. When the connecting post 36 rotates counterclockwise forward, it pushes the drive handle 35 forward, causing the connecting post 36 to slide inside the slide groove. The forward rotation of the drive handle 35 drives the rotating ring 34 counterclockwise. The needle rotates, causing the rotating ring 34 to rotate counterclockwise, which in turn drives the internal gear ring to rotate, thereby causing the three gears to rotate. Each of the three gears rotates, causing the adjacent rotating shaft 32 to rotate. Each rotating shaft 32 rotates counterclockwise, which in turn drives the adjacent striking handle 33 to rotate. Each striking handle 33 rotates, causing the adjacent striking hammer 4 to rotate. When the connecting column 36 rotates to its furthest point from the central axis of the drive shaft 38, the three striking hammers 4 strike the sidewall of the discharge pipe 2, causing vibration in the discharge pipe 2 and the coal powder tank 1. This causes the coal powder adsorbed on the inner arc surface of the discharge pipe 2 and the inner wall of the coal powder tank 1 to fall off, improving the coal powder discharge efficiency. When the connecting column 36 rotates counterclockwise backward, it pushes the drive handle 35 backward, causing the connecting column 36 to slide inside the groove.The drive handle 35 rotates backward, causing the rotating ring 34 to rotate clockwise. The clockwise rotation of the rotating ring 34 causes the internal gear ring to rotate, which in turn causes the three gears to rotate. Each of the three gears rotates, causing the adjacent rotating shaft 32 to rotate clockwise. This rotation of the rotating shaft 32 then rotates the adjacent striking handle 33, which in turn rotates the adjacent striking hammer 4. All three striking hammers 4 move away from the central axis of the discharge pipe 2. As the connecting column 36 rotates in a circular motion, the rotating ring 34 reciprocates periodically, causing the three striking hammers 4 to reciprocate periodically. This achieves periodic intermittent striking of the discharge pipe 2, which, in conjunction with the rotating impeller 8, effectively improves the discharge efficiency of pulverized coal. The discharge pipe 2 is equipped with a conveying pipe 6 in the middle. The conveying pipe 6 is rotatably connected to a rotating shaft 7. The outer surface of the rotating shaft 7 is fixedly connected to evenly distributed impellers 8. The front end of the conveying pipe 6 is equipped with a motor 9. The rear end of the output shaft of the motor 9 is fixedly connected to the front end of the rotating shaft 7. The input end of the motor 9 is electrically connected to the output end of the controller 15. The controller 15 enables the motor 9 to operate. The output shaft of the motor 9 rotates, which drives the rotating shaft 7 to rotate. The rotating shaft 7 rotates, which drives the evenly distributed impellers 8 to rotate. The coal powder falls from the inside of the coal powder tank 1 into the inside of the discharge pipe 2, and then falls into the space of the impeller 8 inside the conveying bin 6 through the discharge pipe 2. As the impeller 8 rotates, the coal powder is discharged through the lower end of the discharge pipe 2, realizing quantitative unloading. The discharge amount can be controlled by adjusting the speed of the impeller 8. Wherein: an electric valve 10 is installed at the lower end of the discharge pipe 2. The input end of the electric valve 10 is electrically connected to the output end of the controller 15. The controller 15 enables the electric valve 10 to operate and open, thereby opening the discharge pipe 2 and providing a channel for the coal powder to fall. Among them, the outer arc surface of the pulverized coal tank 1 is fixedly connected with uniformly distributed annular reinforcing ribs 12, and the uppermost annular reinforcing rib 12 and the lowermost annular reinforcing rib 12 are fixedly connected with uniformly distributed vertical reinforcing ribs 13. The annular reinforcing ribs 12 and the vertical reinforcing ribs 13 intersect each other, thereby improving the support strength of the side wall of the pulverized coal tank 1 and thus improving the overall support strength of the pulverized coal tank 1.

[0016] The working principle of the coal powder silo for coal powder processing and collection provided by this utility model is as follows: During operation, personnel first stably place the coal powder tank 1, the discharge pipe 2, and other mechanisms in a horizontal working area. After stable placement, personnel add coal powder into the coal powder tank 1 through the feed pipe 11. The coal powder accumulates and is stored inside the coal powder tank 1. When it is necessary to discharge the coal powder, the controller 15 activates the electric valve 10, which opens the discharge pipe 2. Simultaneously, the controller 15 activates the motor 9, whose output shaft rotates, driving the rotating shaft 7 to rotate. The rotating shaft 7 then drives the evenly distributed impellers 8 to rotate, causing the coal powder to fall from the inside of the coal powder tank 1 into the discharge pipe 2. Inside, the coal powder falls through the discharge pipe 2 into the space of the impeller 8 inside the conveying bin 6. As the impeller 8 rotates, it is discharged through the lower end of the discharge pipe 2, achieving quantitative unloading. The discharge volume can be controlled by adjusting the speed of the impeller 8. At the same time, the controller 15 drives the motor 39. The output shaft of the motor 39 rotates, driving the drive shaft 38 to rotate. The drive shaft 38 rotates, driving the rotating handle 37 to rotate, which in turn causes the connecting column 36 to rotate around the central axis of the drive shaft 38. When the connecting column 36 rotates counterclockwise forward, it pushes the drive handle 35 forward. The connecting column 36 slides inside the chute. The drive handle 35 rotates forward, driving the rotating ring 34 to rotate counterclockwise. The rotating ring 34 rotates counterclockwise, driving the internal gear ring to rotate. This causes the three gears to rotate, and each of the three gears drives the adjacent rotating shaft 32 to rotate. The rotating shaft 32 rotates counterclockwise, and each of the rotating shaft 32 drives the adjacent striking handle 33 to rotate. Each of the striking handle 33 drives the adjacent striking hammer 4 to rotate. When the connecting column 36 rotates to its furthest point from the central axis of the drive shaft 38, the three striking hammers 4 strike the side wall of the discharge pipe 2, causing vibration in the discharge pipe 2 and the coal powder tank 1. This causes the coal powder adsorbed on the inner arc surface of the discharge pipe 2 and the inner wall of the coal powder tank 1 to fall off, improving the coal powder discharge efficiency. When the connecting column 36 rotates counterclockwise backward, it pushes the drive handle 35 backward. The connecting column 36 slides inside the groove, and the drive handle 35 moves backward... The rotation drives the rotating ring 34 to rotate clockwise, which in turn drives the internal gear ring to rotate, thereby causing the three gears to rotate. The rotation of the three gears drives the adjacent rotating shaft 32 to rotate, and the rotating shaft 32 rotates clockwise. The rotation of the rotating shaft 32 drives the adjacent striking handle 33 to rotate, and the rotation of the striking handle 33 drives the adjacent striking hammer 4 to rotate. The three striking hammers 4 move away from the central axis of the discharge pipe 2. As the connecting column 36 rotates in a circular motion, the rotating ring 34 rotates periodically, which in turn causes the three striking hammers 4 to rotate periodically, thereby achieving periodic intermittent striking of the discharge pipe 2. This, together with the rotating impeller 8, effectively improves the discharge efficiency of pulverized coal.

[0017] It is worth noting that the controller 15 disclosed in the above embodiments can be an S7-300, and the controller 15 controls the operation of motor 1 39, motor 2 9 and electric valve 10 using methods commonly used in the prior art.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
