Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, and in particular to a dust collector for a coal conveying system transfer station. Background Technology

[0002] In modern industrial production, especially in coal transportation and processing, coal conveying system transfer stations play a crucial role in material transfer. However, the material transfer process generates a large amount of dust, which not only pollutes the working environment and affects the health of workers, but also may cause safety hazards such as dust explosions. Therefore, efficient and reliable dust collectors have become an indispensable key piece of equipment in coal conveying system transfer stations, and their performance directly affects the environmental protection level, operational stability, and safety of the entire production system.

[0003] Currently, most dust collectors used in coal conveying system transfer stations employ filter bags to filter and purify dust-laden gases. Over long-term use, these filter bags inevitably become clogged with dust. Traditional solutions for filter bag clogging often require manual entry into the dust collector for cleaning, which is not only cumbersome and time-consuming but also poses safety risks. Frequent manual maintenance also increases operating costs for businesses. Furthermore, the existing dust collectors have relatively complex filter bag disassembly and installation structures, requiring various tools and considerable time to replace filter bags, leading to increased equipment downtime and impacting production schedules. The complex disassembly process can also damage other components of the dust collector, shortening its overall lifespan. Therefore, designing a dust collector that enables self-cleaning of filter bags and facilitates easy disassembly and installation has become a crucial technical challenge for improving the performance of dust collection equipment in coal conveying system transfer stations. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a dust collector for a coal conveying system transfer station. It achieves self-cleaning of the filter bag through mechanical vibration, reduces maintenance costs, ensures operating efficiency, simplifies the filter bag replacement process, and improves the overall performance of the equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The dust collector for a coal conveying system transfer station includes a control room and a filter chamber. The lower side of the control room is fixedly connected to the upper side of the filter chamber. A discharge port is fixedly connected to the lower side of the filter chamber. An air outlet is opened on the right side of the filter chamber, and an air inlet is opened on the left side of the filter chamber. A connecting pipe is fixedly connected to the upper interior of the control room. A cover plate is rotatably connected to the upper side of the connecting pipe. A partition is fixedly connected to the lower inner wall of the filter chamber. A filter bag is fixedly connected inside the partition. A connecting plate is fixedly connected to the other side of the filter bag. A fixing component is provided on the upper side of the connecting plate. A handle is fixedly connected to the upper side of the connecting plate. A sliding plate is slidably connected to the inside of the control room. A vibration component is provided on the upper side of the sliding plate.

[0007] Furthermore, the vibration assembly includes a motor fixedly connected to the upper side of the sliding plate, an auxiliary plate fixedly connected to the rotating end of the motor, and fixed rods fixedly connected to the lower sides of the auxiliary plates on both sides.

[0008] Furthermore, the fixing component includes an upper connecting rod fixedly connected to the inner wall of the connecting pipe, a lower connecting rod fixedly connected to the upper side of the connecting plate, a sliding cover slidably connected to the outer wall of the lower connecting rod, and a hole opened inside the lower connecting rod, with a movable ball disposed inside the hole.

[0009] Furthermore, a connecting shaft is rotatably connected to the outer wall of the fixed rod, and a rotating block is rotatably connected to the upper side of the connecting shaft. The outer wall of the rotating block is fixedly connected to the upper side of the control room.

[0010] Furthermore, a telescopic rod is fixedly connected to the right side of the control room, and a spring is sleeved on the outer wall of the telescopic rod.

[0011] Furthermore, a baffle is slidably connected to the inner wall of the lower connecting rod, and a spring is provided on the upper side of the baffle.

[0012] Furthermore, a protrusion is fixedly connected to the lower side of the inner wall of the sliding cover, the outer wall of the protrusion is disposed on the outside of the movable ball, and a second spring is sleeved on the outer wall of the lower connecting rod, the outer wall of the second spring is disposed on the upper side of the protrusion.

[0013] Furthermore, a rubber sleeve is fixedly connected to the lower side of the connecting pipe, and the other end of the rubber sleeve is fixedly connected to the upper side inside the sliding plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. The innovative vibration structure of this dust collector provides a strong guarantee for the continuous and efficient operation of the equipment. When the filter bag becomes slightly clogged due to long-term use, the motor drives the auxiliary plate to rotate, and the fixed rod makes a circular motion, causing the sliding plate to move up and down, thereby pulling the filter bag back and forth. Combined with the spring sleeved on the outer wall of the telescopic rod, the vibration generated in this process effectively shakes off the dust adhering to the outer wall of the filter bag. This design eliminates the need for frequent manual cleaning of the filter bag, greatly reducing maintenance workload and labor costs; at the same time, timely dust removal prevents clogging of the filter bag pores, maintaining high air permeability and filtration efficiency, ensuring stable operation of the dust collector, reducing equipment downtime due to decreased filtration efficiency, and improving the overall operating efficiency of the coal conveying system.

[0016] 2. In this utility model, the dust collector's convenient disassembly structure fully considers the needs of filter bag replacement. Through the ingenious cooperation of components such as the upper and lower connecting rods, sliding cover, and movable ball, the filter bag assembly can be quickly separated and installed simply by sliding the sliding cover. This design significantly simplifies the filter bag replacement process, greatly shortens the replacement time, allows the equipment to resume operation more quickly, and reduces the impact of downtime on production. In addition, the disassembly process is simple to operate, reducing the labor intensity of workers and reducing the risk of component damage that may be caused by complex disassembly operations, thus extending the service life of each component of the dust collector.

[0023] 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.

[0024] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a dust collector for a coal conveying system transfer station, comprising a control room 1 and a filter chamber 5. The lower side of the control room 1 is fixedly connected to the upper side of the filter chamber 5. A discharge port 6 is fixedly connected to the lower side of the filter chamber 5. An air outlet 3 is opened on the right side of the filter chamber 5, and an air inlet 4 is opened on the left side of the filter chamber 5. A connecting pipe 11 is fixedly connected to the upper side of the control room 1. A cover plate 2 is rotatably connected to the upper side of the connecting pipe 11. A partition plate 7 is fixedly connected to the lower side of the inner wall of the filter chamber 5. A filter bag 8 is fixedly connected inside the partition plate 7. A connecting plate 10 is fixedly connected to the other side of the filter bag 8. An upper connecting rod 17 is provided on the upper side of the connecting plate 10. A lower connecting rod 22 is fixedly connected to the upper side of the connecting plate 10. A sliding cover 23 is slidably connected to the outer wall of the lower connecting rod 22. A hole is opened inside the lower connecting rod 22, and a movable ball 25 is provided inside the hole. A handle 9 is fixedly connected to the upper side of the connecting plate 10. A sliding plate 12 is slidably connected inside the control room 1. A motor 19 is installed on the upper side of the sliding plate 12. An auxiliary plate 18 is fixedly connected to the rotating end of the motor 19. Fixed rods are fixedly connected to the lower side of the auxiliary plates 18 on both sides.

[0025] Specifically, during the use of the device, dust accumulates in the pores of the filter bag 8 after long-term use, reducing filtration efficiency. For minor blockages, manual cleaning of the filter bag 8 is too cumbersome. Therefore, a vibration design is implemented to address minor blockages and maintain the device's continuous high efficiency. First, the motor 19 inside the sliding plate 12 drives the auxiliary plate 18 to rotate. The auxiliary plates 18 on both sides rotate the central fixed rod, causing the connecting shaft 16 to rotate in a circular motion. Because the fixed rod is not at the center, the sliding plate 12 and the control chamber 1 experience relative vertical displacement, pulling the elastic filter bag 8. The back-and-forth stretching of the filter bag 8 vibrates down the mud on the outer wall, making it less prone to adhesion. The upper side of the connecting pipe 11 is connected to the upper side of the control chamber 1, and the lower side is connected to a rubber sleeve to prevent relative displacement between the control chamber 1 and the sliding plate 12, thus preventing gas leakage. The spring 13 sleeved on the outer wall of the telescopic rod 14 intensifies the vibration of the device and connects the control chamber 1 and the sliding plate 12. Because the internal filter bag 8 needs to be replaced frequently, a structure design was implemented that facilitates disassembly and installation. First, the sliding cover 23 on the outer wall of the lower connecting rod 22 can be slid upwards to insert the upper connecting rod 17 into the pre-reserved position. Then, the sliding cover 23 can be released. Similarly, when disassembly is required, the sliding cover 23 can be slid downwards to easily separate the two parts. During this process, sliding the sliding cover 23 upwards provides space for the movable ball 25 to move. When inserted, the movable ball 25 will move to one side. Once fully inserted, the sliding cover 23 can be released. A spring 26 is located on the lower side of the sliding cover 23, and a limit plate is also present on the lower side of the sliding cover 23. 23 will be pushed to the appropriate position, and the internal protrusion 24 will stay at the same level as the movable ball 25. The outer wall of the upper connecting rod 17 has a groove, so the protrusion 24 abuts against one side, and the movable ball 25 will be restricted in the groove of the upper connecting rod 17. The hole inside the lower connecting rod 22 is slightly larger than the movable ball 25, but it will not allow the movable ball 25 to go out. When separated, similarly, by sliding the sliding cover 23 upward, the movable ball 25 will move to the side, and the upper connecting rod 17 can move out. The internal spring 20 and baffle 21 provide the previous compression capacity. The bottom side of the filter bag 8 is fixedly connected to the bottom side of the partition 7 by the connecting ring.

[0026] Reference Figure 3 and Figure 4A connecting shaft 16 is rotatably connected to the outer wall of the fixed rod. A rotating block 15 is rotatably connected to the upper side of the connecting shaft 16. The outer wall of the rotating block 15 is fixedly connected to the upper side of the inside of the control room 1. A telescopic rod 14 is fixedly connected to the right side of the inside of the control room 1. A spring 13 is sleeved on the outer wall of the telescopic rod 14. A baffle 21 is slidably connected to the inner wall of the lower connecting rod 22. A spring 20 is set on the upper side of the baffle 21. A protrusion 24 is fixedly connected to the lower side of the inner wall of the sliding cover 23. The outer wall of the protrusion 24 is set outside the movable ball 25. A spring 26 is sleeved on the outer wall of the lower connecting rod 22. The outer wall of the spring 26 is set on the upper side of the protrusion 24. A rubber sleeve is fixedly connected to the lower side of the connecting pipe 11. The other end of the rubber sleeve is fixedly connected to the upper side of the inside of the sliding plate 12.

[0027] Specifically, regarding the structural connection and operational details of the device, the outer wall of the fixed rod is rotatably connected to the rotating block 15 via a fixed connecting shaft 16. The rotating block 15 is securely fixed to the upper side inside the control chamber 1, providing support and a rotation axis for the fixed rod's rotation. The telescopic rod 14, fixedly connected to the right side inside the control chamber 1, has a spring 13 fitted on its outer wall. This spring 13 connects the control chamber 1 and the sliding plate 12, ensuring their structural connection. Furthermore, when the sliding plate 12 moves, the spring 13 intensifies the device's vibration effect through its elastic deformation. For the auxiliary structure for disassembling and installing the filter bag 8, the baffle 21 slidably connected to the inner wall of the lower connecting rod 22 and the upper spring 20 provide elastic force to the baffle 21 during disassembly and installation, thus assisting in the control of the movable ball 25. The protrusion 24 fixedly connected to the lower inner wall of the sliding cover 23 cooperates with the movable ball 25. The spring 26 sleeved on the outer wall of the sliding cover 23 provides an upward elastic force to the protrusion 24. When the sliding cover 23 slides, the protrusion 24 controls the movement of the movable ball 25, thereby achieving a stable connection and convenient separation between the upper connecting rod 17 and the lower connecting rod 22. The rubber sleeve fixedly connected to the lower side of the connecting pipe 11 is fixedly connected to the upper inner side of the sliding plate 12 at the other end. This rubber sleeve can effectively prevent gas leakage when the control chamber 1 and the sliding plate 12 are relatively displaced, ensuring the sealing and stability of gas transmission inside the device and ensuring the overall efficient operation of the dust collector.

[0028] Working Principle: As usage time increases, when the filter bag 8 becomes slightly clogged, the motor 19 in the control chamber 1 starts, driving the auxiliary plate 18 to rotate. The auxiliary plate 18 then drives the fixed rod to perform a circular motion. Because the fixed rod is off-center from the rotation center, the sliding plate 12 experiences vertical displacement within the control chamber 1. The sliding plate 12, through the connecting structure, pulls the elastic filter bag 8, causing it to stretch back and forth. During this process, the spring 13 sleeved on the outer wall of the telescopic rod 14 intensifies the vibration effect through elastic deformation, shaking off the dust adhering to the outer wall of the filter bag 8. The dust falls into the bottom of the filter chamber 5 and is discharged through the outlet 6, achieving self-cleaning of the filter bag 8 and maintaining the high-efficiency filtration performance of the dust collector. When the filter bag 8 needs to be replaced, slide the sliding cover 23 upwards. The protrusion 24 on the lower side of the sliding cover 23 no longer restricts the movable ball 25. With the assistance of spring 20 and baffle 21, the movable ball 25 moves to the side, releasing the restriction on the upper connecting rod 17. The upper connecting rod 17 can then be pulled out from the lower connecting rod 22, separating the filter bag 8 assembly for replacement. During installation, align the upper connecting rod 17 with the lower connecting rod 22 and insert it. During insertion, the movable ball 25 moves to one side. After full insertion, release the sliding cover 23. Under the elastic force of spring 26, the sliding cover 23 returns to its original position, and the protrusion 24 abuts against the movable ball 25, causing it to engage with the groove of the upper connecting rod 17, completing the installation and fixing of the filter bag 8. At the same time, the rubber sleeve on the lower side of the connecting pipe 11 always ensures the sealing between the control chamber 1 and the sliding plate 12, preventing gas leakage and ensuring the stable and efficient operation of the entire dust removal process.

[0029] 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.
