Technical Field
[0001] This utility model relates to the field of light-burned dolomite production technology, specifically a bag filter dust collector for light-burned dolomite production. Background Technology
[0002] In the production of light-burned dolomite, the process of calcining dolomite at high temperatures to produce light-burned dolomite products is accompanied by the emission of a large amount of dust-laden flue gas. This flue gas is characterized by high temperature (flue gas temperature can reach 400-600℃), high dust concentration, and easy agglomeration of dust. Because light-burned dolomite dust contains components such as CaO and MgO, it is easy to adsorb water vapor or stick together in a high-temperature environment, forming a highly adhesive dust layer, which puts strict requirements on the filtration performance and dust removal effect of dust removal equipment.
[0003] A bag filter dust collector for the production of lightly calcined dolomite, disclosed in CN215310944U, is provided with a tower locking assembly to ensure a sealed connection between the dust collection box and the ash hopper, effectively preventing dust leakage. The bottom of the ash hopper is sealed by the inclusion of a plug groove, an opening groove, and a plug plate.
[0004] This baghouse dust collector for light-burned dolomite production can perform preliminary filtration of flue gas through its filter plates. However, the device lacks a structure for cleaning the filter plates. When the filter plates become clogged during use, operators must stop the machine to clean them, which affects work efficiency. Therefore, improvements are needed. Utility Model Content
[0005] The purpose of this invention is to provide a bag filter dust collector for the production of lightly calcined dolomite, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a bag filter dust collector for light-burned dolomite production, comprising a dust collector body, a filter mechanism provided at the bottom of the dust collector body, and an auxiliary mechanism provided at the top of the inner side of the dust collector body;
[0007] The filtration mechanism includes a drive motor, which is fixedly connected to the middle of the right side of the dust collector. A rotating rod is fixedly connected to the left side of the drive motor and rotatably connected to the inside of the dust collector body. A filter bag is fixedly connected to the periphery of the rotating rod. A scraper is fixedly connected to the back end of the inside of the dust collector body. A dust collection tray is slidably connected to the bottom of the inside of the dust collector body. A sealing plate is fixedly connected to the right side of the dust collection tray. A limiting plate is fixedly connected to the left side of the sealing plate. A fixing plate is provided on the top of the limiting plate. The fixing plate is fixedly connected to the right side of the front and rear sides of the dust collector body. An insert rod is inserted into the inside of the fixing plate and is inserted into the inside of the limiting plate.
[0008] Preferably, the scraper is located at the bottom back end of the bag filter cylinder, and the front of the scraper is in contact with the bottom back end of the bag filter cylinder. When the bag filter cylinder rotates, the scraper can scrape off the dust attached to the surface of the bag filter cylinder, so that the dust can fall into the dust collection tray.
[0009] Preferably, the sealing plate is located on the right side of the dust collector body, and the left side of the sealing plate is in close contact with the right side of the dust collector body. The sealing plate can block the opening on the right side of the dust collector body, making it difficult for dust to be discharged from the opening.
[0010] Preferably, the auxiliary mechanism includes a hydraulic cylinder, which is fixedly connected to the left side of the dust collector body. A cleaning brush is fixedly connected to the right side of the hydraulic cylinder. A filter bag body is provided on the top of the cleaning brush. A pull plate is fixedly connected to the right side of the filter bag body. A U-shaped plate is fixedly connected to the right side of the pull plate. An arc-shaped plate is fixedly connected to the top periphery of the dust collector body. A fixing rod is fixedly connected to the right side of the arc-shaped plate. A rotating plate is rotatably connected to the periphery of the fixing rod.
[0011] Preferably, the dust collector body has a groove on its inner side that corresponds to the movement trajectory of the cleaning brush, and the cleaning brush is slidably connected inside the groove. Through the groove, the cleaning brush can move left and right inside the dust collector body to clean the bottom of the filter bag body.
[0012] Preferably, the top inner side of the dust collector body is provided with a sliding groove corresponding to the movement trajectory of the filter bag body, and the filter bag body is slidably connected to the inside of the sliding groove. Through the sliding groove, the filter bag body can slide inside the dust collector, making it convenient for staff to remove and clean it.
[0013] Preferably, the U-shaped plate has a slot on its inner side that corresponds to the position of the rotating plate, and the rotating plate is rotatably connected to the inside of the slot. When the rotating plate is inserted into the U-shaped plate, it can limit the position of the U-shaped plate and the pull plate, making the filter bag body more stable when in use.
[0014] Compared with the prior art, this utility model provides a bag filter dust collector for the production of lightly calcined dolomite, which has the following beneficial effects:
[0015] 1. This baghouse dust collector for light-burned dolomite production features a filter mechanism in which a drive motor rotates a rotating rod and a filter bag. Combined with a scraper attached to the inner back of the dust collector body, the scraper removes dust adhering to the filter bag's surface in real time during rotation, ensuring continuous and stable operation of the dust collection system. The sliding dust collection drawer allows scraped and swept dust to fall directly into it. When dust accumulates to a certain amount, simply pull out the insert rod to remove the dust collection drawer from the right side of the dust collector body for cleaning, eliminating the need to disassemble equipment parts and reducing worker workload.
[0016] 2. In this baghouse dust collector for light-burned dolomite production, the hydraulic cylinder of the auxiliary mechanism drives the cleaning brush to slide along the slide groove, which can sweep the dust on the surface of the filter bag body laterally, so that the filter bag body always maintains good air permeability and ensures the continuous and stable operation of the dust collection system.

[0026] This utility model provides the following technical solution:
[0027] Example 1
[0028] Please see Figure 1-5 This utility model provides a technical solution: a bag dust collector for the production of lightly calcined dolomite, including a dust collector body 1, a filter mechanism 3 is provided at the bottom of the dust collector body 1, and an auxiliary mechanism 2 is provided at the top of the inner side of the dust collector body 1.
[0029] The filtration mechanism 3 includes a drive motor 34, which is fixedly connected to the middle of the right side of the dust collector. A rotating rod 32 is fixedly connected to the left side of the drive motor 34. The rotating rod 32 is rotatably connected to the inside of the dust collector body 1. A filter bag 33 is fixedly connected to the outside of the rotating rod 32. A scraper 39 is fixedly connected to the back end of the inside of the dust collector body 1. A dust collection tray 31 is slidably connected to the bottom of the inside of the dust collector body 1. A sealing plate 35 is fixedly connected to the right side of the dust collection tray 31. A limiting plate 38 is fixedly connected to the left side of the sealing plate 35. A fixing plate 37 is provided on the top of the limiting plate 38. The fixing plate 37 is fixedly connected to the right side of the front and rear sides of the dust collector body 1. An insertion rod 36 is inserted into the inside of the fixing plate 37. The insertion rod 36 is inserted into the inside of the limiting plate 38.
[0030] Furthermore, a scraper 39 is disposed at the bottom back end of the bag filter cartridge 33, and the front of the scraper 39 is in contact with the bottom back end of the bag filter cartridge 33. When the bag filter cartridge 33 rotates, the scraper 39 can scrape off the dust adhering to the surface of the bag filter cartridge 33, allowing the dust to fall into the dust collection tray 31.
[0031] Furthermore, the sealing plate 35 is located on the right side of the dust collector body 1, and the left side of the sealing plate 35 is in close contact with the right side of the dust collector body 1. The sealing plate 35 can block the opening on the right side of the dust collector body 1, making it difficult for dust to be discharged from the opening.
[0032] Example 2
[0033] Please see Figure 1-5 Furthermore, based on Embodiment 1, the auxiliary mechanism 2 includes a hydraulic cylinder 22, which is fixedly connected to the left side of the dust collector body 1. A cleaning brush 21 is fixedly connected to the right side of the hydraulic cylinder 22. A filter bag body 23 is provided on the top of the cleaning brush 21. A pull plate 24 is fixedly connected to the right side of the filter bag body 23. A U-shaped plate 28 is fixedly connected to the right side of the pull plate 24. An arc-shaped plate 26 is fixedly connected to the top of the outer periphery of the dust collector body 1. A fixing rod 27 is fixedly connected to the right side of the arc-shaped plate 26. A rotating plate 25 is rotatably connected to the outer periphery of the fixing rod 27.
[0034] Furthermore, a groove corresponding to the movement trajectory of the cleaning brush 21 is provided on the inner side of the dust collector body 1, and the cleaning brush 21 is slidably connected inside the groove. Through the groove, the cleaning brush 21 can move left and right inside the dust collector body 1 to clean the bottom of the filter bag body 23.
[0035] Furthermore, a sliding groove corresponding to the movement trajectory of the filter bag body 23 is provided on the top inner side of the dust collector body 1, and the filter bag body 23 is slidably connected to the inside of the sliding groove. Through the sliding groove, the filter bag body 23 can slide inside the dust collector, making it convenient for staff to remove and clean it.
[0036] Furthermore, a slot corresponding to the position of the rotating plate 25 is provided on the inner side of the U-shaped plate 28, and the rotating plate 25 is rotatably connected to the inside of the slot. When the rotating plate 25 is inserted into the U-shaped plate 28, it can limit the position of the U-shaped plate 28 and the pull plate 24, making the filter bag body 23 more stable when in use.
[0037] In actual operation, when this device is used, when dust is generated during the production of lightly calcined dolomite, the dust is introduced into the dust collector body 1 through the opening on the left side of the dust collector body 1, causing the dust to move upward and be filtered through the bag filter cartridge 33. When the bag filter cartridge 33 is in use, the operator turns on the drive motor 34, which drives the bag filter cartridge 33 to rotate slowly through the rotating rod 32. The back end of the bag filter cartridge 33 is scraped by the scraper 39, which can scrape the dust attached to the surface of the bag filter cartridge 33, so that the dust can fall into the dust collection tray 31.
[0038] Dust passing through the filter cartridge 33 continues to float upwards, allowing it to pass through the filter bag body 23 for filtration. The dust adheres to the bottom of the filter bag body 23, while the air passing through is discharged upwards. When the filter bag body 23 becomes clogged, the hydraulic cylinder 22 is opened, causing it to push the cleaning brush 21 to move. The cleaning brush 21 cleans the bottom of the filter bag body 23, and the dust that falls off after cleaning adheres to the outer surface of the filter cartridge 33. When the filter cartridge 33 rotates, the scraper 39 continues to scrape off the dust adhering to the outside, allowing the dust to fall into the dust collection tray 31.
[0039] When the filter bag body 23 is severely clogged, the operator reverses the rotation plate 25 to move the rotation plate 25 away from the inside of the U-shaped plate 28, and then pulls the pull plate 24 to move the filter bag body 23 so that the filter bag body 23 can be moved out of the inside of the dust collector body 1 for easy cleaning.
[0040] When it is necessary to clean the dust inside the dust collection tray 31, the operator pulls the insert rod 36 upwards, so that the insert rod 36 is away from the inside of the limit plate 38, so that the operator can pull the sealing plate 35, so that the sealing plate 35 can move the dust collection tray 31 out of the dust collector body 1, making it convenient for the operator to clean the dust inside the dust collection tray 31.
