Description

Technical Field

[0001] This utility model belongs to the field of converter silo dust removal technology, and in particular relates to a converter silo dust removal pipeline anti-clogging device. Background Technology

[0002] Steelmaking plants require belt conveyors for converter production. The conveyor belts transport materials to a high-level silo via a transfer station, where a material distribution trolley distributes the material into the silo. Dust is generated during unloading. Steelmaking plants typically use single-point dust collectors on the distribution trolleys and dust collection pipes inside the silo, utilizing the airflow from the converter's secondary dust collector to maintain negative pressure inside the silo during material unloading, thus ensuring effective dust control. However, during operation, materials such as plastic bags, straw, paper scraps, and garbage are drawn into the dust collection pipes under negative pressure, clogging the ash discharge pipe of the dust collection silo. This prevents ash from being discharged, requiring 30 minutes of processing each time. Sometimes, multiple blockages necessitate manual intervention for over an hour, impacting environmental dust control effectiveness, failing to achieve ultra-low emissions, wasting time and labor, increasing employee workload, and reducing work efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a device for preventing blockage of dust removal pipes in converter silos, so as to solve the problems existing in the prior art.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A dust removal pipeline anti-clogging device for a converter silo includes a filter box connected to a flange on the dust removal pipeline. The filter box is equipped with a partition that divides the filter box into two chambers. Both sides of the filter box have an upper insertion port, a middle insertion port, a cleaning port, and a lower insertion port from top to bottom. An upper baffle, a lower baffle, and a filter plate are respectively inserted into the upper insertion port, the lower insertion port, and the middle insertion port. An upper cover plate is movably connected to the outer wall of the filter box at the upper insertion port and the middle insertion port. A cleaning cover plate is movably connected to the outer wall of the filter box at the cleaning port. A lower cover plate is movably connected to the outer wall of the filter box at the lower insertion port.

[0006] Furthermore, the top and bottom of the filter box are connected to the dust removal pipeline, and the upper baffle, lower baffle, and filter plates on both sides of the filter box are provided with sliding grooves, and the upper baffle, lower baffle, and filter plates on both sides are slidably connected in the corresponding sliding grooves.

[0007] Furthermore, several first round tubes are welded around or on both sides of the upper cover plate, lower cover plate, and cleaning cover plate, and several second round tubes are welded on the outer walls of the filter box around or on both sides of the upper cover plate, lower cover plate, and cleaning cover plate. The first round tubes and second round tubes are staggered, and pins are inserted into the staggered first round tubes and second round tubes around or on both sides of the upper cover plate, lower cover plate, and cleaning cover plate.

[0008] Furthermore, rubber pads are placed between the upper cover plate, lower cover plate, cleaning cover plate and the outer wall of the filter box, and the rubber pads are attached to the corresponding upper cover plate, lower cover plate and cleaning cover plate.

[0009] This utility model has the following beneficial effects:

[0010] 1. This utility model can filter out debris in the dust removal pipe, thereby preventing debris from clogging the dust removal ash hopper, thus avoiding the need for unblocking work due to the inability to discharge ash, reducing workload and avoiding impact on production.

[0011] 2. The upper and lower baffles separate the chambers inside the filter box, making it easier to pick up debris inside the chamber and thus preventing excessive accumulation of debris from clogging the dust removal pipes.

[0012] 3. While cleaning debris in one chamber, the other chamber is being cleaned normally, so there is no need to shut down the dust collector, thus further avoiding production delays. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with specific embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.

[0020] like Figure 1-5As shown, an anti-clogging device for a converter silo dust removal pipeline 1 is provided. A filter box 2 is connected to the upper flange of the dust removal pipeline 1. A partition 3 divides the filter box 2 into two chambers. Both sides of the filter box 2 have an upper insertion port 4, a middle insertion port 5, a cleaning port 6, and a lower insertion port 7, arranged from top to bottom. An upper baffle 8, a lower baffle 9, and a filter plate 10 are respectively inserted into the upper insertion port 4, the lower insertion port 7, and the middle insertion port 5. An upper cover plate 11 is movably connected to the outer wall of the filter box 2 at the upper insertion port 4 and the middle insertion port 5. A cleaning cover plate 12 is movably connected to the outer wall of the filter box 2 at the cleaning port 6. A lower cover plate 13 is movably connected to the outer wall of the filter box 2 at the lower insertion port 7. The filter plate 10 is a device with filter holes, which can intercept impurities and allow the dust removal airflow to pass through.

[0021] The top and bottom of the filter box 2 are connected to the dust removal pipe 1. The inner walls of the filter box 2 on both sides of the upper baffle 8, lower baffle 9, and filter plate 10 are provided with sliding grooves 14. The upper baffle 8, lower baffle 9, and filter plate 10 are slidably connected in the corresponding sliding grooves 14.

[0022] Several first round tubes 15 are welded around or on both sides of the upper cover plate 11, lower cover plate 13, and cleaning cover plate 12. Several second round tubes 16 are welded on the outer wall of the filter box 2 around or on both sides of the upper cover plate 11, lower cover plate 13, and cleaning cover plate 12. The first round tubes 15 and second round tubes 16 are staggered. Pins 17 are inserted into the staggered first round tubes 15 and second round tubes 16 around or on both sides of the upper cover plate 11, lower cover plate 13, and cleaning cover plate 12.

[0023] Rubber pads 18 are placed between the upper cover plate 11, the lower cover plate 13, the cleaning cover plate 12 and the outer wall of the filter box 2. The rubber pads 18 are attached to the corresponding upper cover plate 11, lower cover plate 13, and cleaning cover plate 12.

[0024] The working principle of this utility model is as follows:

[0025] In use, connect the upper and lower flanges of the filter box 2 to the dust collection pipe 1, pull out the upper baffle 8 and lower baffle 9, leave the filter plate 10 in the middle insertion port 5, and fix the upper cover plate 11, lower cover plate 13, and cleaning cover plate 12 to the filter box 2 with pins 17. When the dust collector is working, the airflow is from bottom to top, which creates negative pressure in the bottom dust collection pipe 1 (connected to the hopper), and in turn creates negative pressure in the hopper. When debris is drawn into the dust collection pipe 1, it is intercepted by the filter plate 10, thus preventing blockage of the dust collection ash hopper discharge pipe. Regularly clean the accumulated debris. During cleaning, there is no need to turn off the dust collector. Simply pull out the pins 17 on the upper cover 11 and lower cover 13 outside any chamber in the filter box 2, and insert the upper baffle 8 and lower baffle 9 into the upper insertion port 4 and lower insertion port 7 respectively (after insertion, one end of the upper baffle 8 and lower baffle 9 abuts against the partition 3), thus isolating the upper and lower ends of that chamber, preventing airflow from passing through it. Pull out the pins 17 on the cleaning cover 12 (you can leave the pins 17 on the lower side of the cleaning cover 12 to form a hinge; flipping down the cleaning cover 12 will expose the cleaning port 6). With the chamber isolated, it is no longer under negative pressure, so debris falls onto the lower baffle 9. Picking out the debris completes the cleaning. Alternatively, the filter plate 10 can be pulled out for cleaning.
