Description

Technical Field

[0001] This utility model relates to the technical field of baghouse dust collectors, specifically a baghouse dust collector with easily removable filter bags. Background Technology

[0002] A baghouse dust collector is a dry dust filtration device suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When the dust-laden gas enters the baghouse dust collector, large and heavy dust particles settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter media, the dust is trapped, thus purifying the gas.

[0003] According to a public notice (Announcement No.: CN221788629U) regarding a baghouse dust collector with easy filter bag replacement, the aforementioned application achieves the advantage of easy filter bag replacement through the cooperation of the housing, tube sheet, dust collector bag, slot, shell, moving plate, insert plate, crossbar, spring, blowpipe, air tank, and electromagnetic pulse valve. This solves some defects in the use of previous baghouse dust collectors, such as the lack of easy filter bag replacement, which led to the filter bags becoming less effective after long-term use, thus reducing the effectiveness of the baghouse dust collector and failing to meet the current market demand.

[0004] However, in actual use, replacing a single filter bag in the aforementioned baghouse dust collector requires opening the equipment and having staff use tools or reach inside to disassemble it. This disassembly method is inefficient and affects the normal maintenance efficiency of the device. Therefore, we propose a baghouse dust collector that facilitates filter bag removal. Utility Model Content

[0005] The purpose of this invention is to provide a bag filter dust collector with easy-to-remove filter bags, 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 with easy filter bag removal, comprising a body, an inspection door on the side of the body, an air inlet pipe on the bottom side wall of the body, an exhaust pipe on the top of the body, a ash discharge valve fixedly installed on the bottom outer wall of the body, a turntable rotatably installed on the inner wall of the body, a dust collector bag detachably installed on the bottom of the turntable, and a switching component inside the body;

[0007] The transposition assembly includes a drive motor, which is fixedly mounted on the outer wall of the machine body. A gear is fixedly mounted on the output end of the drive motor. A mounting slider is slidably mounted on the bottom inner wall of the turntable. A round rod is detachably connected to the lower surface of the mounting slider. A crossbar is fixedly mounted through the inner wall of the round rod. A slide block is slidably mounted on the inner wall of the machine body. A mounting column is fixedly mounted on the upper surface of the slide block. A V-shaped plate is fixedly mounted through the top inner wall of the mounting column.

[0014] Compared with the prior art, this utility model provides a bag filter dust collector with convenient filter bag removal, which has the following beneficial effects:

[0015] 1. This baghouse dust collector with easy filter bag removal features a shifting component and a V-shaped plate. As the turntable continues to rotate, the round rod is guided by the outer surface of the V-shaped plate to move away from the center of the turntable until the mounting slider moves the dust collector bag to the end of the V-shaped plate. At this point, the drive motor is turned off, and the operator can easily disassemble and replace the dust collector bag without having to reach into the machine body. This provides a larger operating space and higher disassembly and installation efficiency.

[0016] 2. This baghouse dust collector, which facilitates filter bag removal, is equipped with a lifting assembly. The crossbar presses against the short plate section, causing it to shift downwards. Eventually, the crossbar moves above the arc-shaped support plate. As the installation slider continues to move, the connecting block moves synchronously until the dust collector bag and the round rod reach the top of the V-shaped plate. The arc-shaped support plate then supports the crossbar, eliminating the need for manual lifting of the dust collector bag during disassembly and installation. This saves time and effort, ensures stability and accuracy during assembly, and improves the maintenance efficiency of the device. Attached Figure Description

[0023] like Figures 1-5As shown, this utility model provides a technical solution: a bag filter dust collector with easy filter bag removal, including a body 1, an inspection door 2 on the side of the body 1, an air inlet pipe 3 on the bottom side wall of the body 1, an exhaust pipe 4 on the top of the body 1, a ash valve 5 fixedly installed on the bottom outer wall of the body 1, a turntable 6 rotatably installed on the inner wall of the body 1, a dust collector bag 7 detachably installed at the bottom of the turntable 6, and a switching component 8 is provided inside the body 1. The switching component 8 includes a drive motor 81, a gear 82, a mounting slider 83, a round rod 84, a crossbar 85, a slide block 86, a mounting column 87, a V-shaped plate 88, a fixing rod 89, and a large spring 810.

[0024] In one embodiment of this utility model, a drive motor 81 is fixedly installed on the outer wall of the machine body 1, a gear 82 is fixedly installed at the output end of the drive motor 81, a mounting slider 83 is slidably installed on the bottom inner wall of the turntable 6, a round rod 84 is detachably connected to the lower surface of the mounting slider 83, a crossbar 85 is fixedly installed through the inner wall of the round rod 84, a slide block 86 is slidably installed on the inner wall of the machine body 1, a mounting column 87 is fixedly installed on the upper surface of the slide block 86, a V-shaped plate 88 is fixedly installed through the top inner wall of the mounting column 87, a fixing rod 89 is fixedly installed on the inner wall of the turntable 6, and a large spring 810 is sleeved on the outer wall of the fixing rod 89.

[0025] Furthermore, multiple sets of dust collector bags 7 are arranged in a circular array and evenly distributed on the lower surface of the turntable 6, thereby forming a large dust collection area inside the machine body 1. The air inlet pipe 3 is located at the lower interior of the machine body 1, allowing dusty exhaust gas to enter the machine body 1 and move upwards. After being filtered by the dust collector bags 7, the gas is discharged upwards through the exhaust pipe 4. At the same time, the bottom of the machine body 1 is designed as an inverted frustum shape, narrow at the bottom and wide at the top, so that the dust filtered inside the machine body 1 and the naturally settled dust will accumulate near the bottom inner wall of the machine body 1, allowing the staff to discharge the dust by opening the ash valve 5. Specifically, the dust collector bags 7 and the maintenance door 2 are set on the same horizontal line, so that the staff can open the maintenance door 2 to maintain the dust collector bags 7.

[0026] Meanwhile, a contact groove with a width matching that of the gear 82 is provided on the outer wall of the body 1, and the thickness of the contact groove is less than that of the turntable 6, so that the internal space of the body 1 can be sealed to a certain extent. Furthermore, the arc-shaped outer wall of the turntable 6 has teeth that mesh with the gear 82 to achieve transmission. Thus, when the drive motor 81 is started, in conjunction with the rotation of the gear 82, the turntable 6 can slowly rotate on the inner wall of the body 1, allowing the dust collector bag 7 to remain in a moving state within the body 1, thereby increasing the dust collection range of the dust collector bag 7 and ensuring the dust collection effect of the device. Furthermore, the left and right sides of the mounting slider 83 are... The turntable 6 has a protrusion and a rectangular groove on its lower surface that matches the size of the mounting slider 83. The inner surfaces of the left and right sides of the rectangular groove have grooves that match the protrusion. This allows the mounting slider 83 to slide along the inner wall of the rectangular groove while also having a certain load-bearing capacity, preventing the dust collector bag 7 installed at its bottom from falling off. Specifically, the bottom end of the round rod 84 is fixedly connected to the top outer wall of the dust collector bag 7, and the top end of the round rod 84 is detachably connected to the lower surface of the mounting slider 83 by bolts, so that the bolts can be removed when the dust collector bag 7 needs to be replaced.

[0027] In addition, the two ends of the fixing rod 89 are fixedly connected to the inner walls of the two ends of the rectangular groove, and the fixing rod 89 is slidably connected to the mounting slider 83. The two ends of the large spring 810 are fixedly connected to the outer wall of one side of the mounting slider 83 and the inner wall of the end of the rectangular groove, respectively. Thus, under the elastic force of the large spring 810, the mounting slider 83 drives the dust collector bag 7 to always be in the rectangular groove near the center of the turntable 6. At the same time, there are two sets of slides 86, and the two sets of slides 86 are mirror images of each other at the two ends of the mounting column 87. A handle is fixedly installed on the outer wall of the mounting column 87 away from the center of the machine body 1, so that the operator can manually pull the handle to control the slide 86 to slide inside the machine body 1. The sliding of the slide 86 can control the V-shaped plate 88 to move closer to or away from the round rod 84.

[0028] In addition, a lifting assembly 9 is provided below the turntable 6. The lifting assembly 9 includes a straight rod 91. A movable groove is provided on the lower surface of the turntable 6. The straight rod 91 is fixedly installed on the inner wall of both ends of the movable groove. A connecting block 92 is fixedly installed through the outer wall of the straight rod 91. A small spring 93 is fixedly connected between the side wall of the connecting block 92 and the inner wall of the end of the movable groove. An arc-shaped support plate 94 is rotatably connected to the bottom side wall of the connecting block 92 through a coil spring.

[0029] In this embodiment of the invention, the arc-shaped support plate 94 includes a long plate segment and a short plate segment, with the short plate segment facing the center of the turntable 6. Simultaneously, the crossbar 85 and the arc-shaped support plate 94 are arranged in the same plane. When the dust collector bag 7 slides away from the center of the turntable 6 as the round rod 84 moves, the crossbar 85 presses against the short plate segment, causing it to shift downwards. Finally, the crossbar 85 moves above the arc-shaped support plate 94 and, as the mounting slider 83 continues to move, drives the connecting block 92 to move synchronously. When the dust collector bag 7 and the round rod 84 reach the top of the V-shaped plate 88, the arc-shaped support plate 94 supports the crossbar 85, eliminating the need for manual lifting of the dust collector bag 7 during disassembly and installation. This saves time and effort, ensures stability and accuracy during assembly, and improves the maintenance efficiency of the device.

[0030] In this utility model, during use, the operator first opens the inspection door 2. Then, by pushing the handle towards the center of the machine body 1, the V-shaped plate 88 slides towards the center of the machine body 1, and then moves to the trajectory of the round rod 84 as the turntable 6 rotates. The operator can use tools such as pins to fix and limit the sliding block 86. As the turntable 6 continues to rotate, the round rod 84 is guided by the outer surface of the V-shaped plate 88 and moves away from the center of the turntable 6 until the installation slider 83 drives the dust collector bag 7 to the end point of the V-shaped plate 88. At this time, the drive motor 81 is turned off, and the operator can easily disassemble and replace the dust collector bag 7 without having to go deep into the interior of the machine body 1. The operating space is larger and the disassembly and installation efficiency is higher. After the replacement is completed, the drive motor 81 is turned on again to move the next set of dust collector bags 7 to the switching position in conjunction with the rotation of the turntable 6. The dust collector bags 7 under the turntable 6 are replaced in sequence in the above manner to complete the disassembly and maintenance of the bag dust collector.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
