Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to a bag dust collector which is convenient to disassemble. Background Art

[0002] The bag filter is a dry dust filtering device. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of the fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the bag filter, the dust with large particles and high specific gravity settles down due to the effect of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, so that the gas is purified. The cloth bags in the existing pulse bag filter need to be replaced after a period of use. When replacing the filter bags on the bag filter, the screws used to install the filter bags need to be removed one by one. The process is cumbersome and inefficient. Secondly, because two adjacent filter bags share a pulse tube, the arrangement spacing between the filter bags is small, resulting in a small disassembly operation space, which is inconvenient for disassembly operations.

An exhaust window 10 is provided in the middle of the plate 7 along the height direction of the bag dust collector housing 1. Side slide plates 8 are fixed on both sides of the detachable plate 7. Both inner side walls of the installation window 3 are provided with installation slide grooves 9. The side slide plates 8 slide into the installation slide grooves 9 from the opening end of the installation window 3. The dust bag 6 is connected to the bottom of the detachable plate 7. A mixed air intake pipe 17 and an exhaust pipe 18 are connected to the bag dust collector housing 1. The mixed air intake pipe 17 and the exhaust pipe 18 are respectively located below and above the installation plate 2. The mixed air intake pipe 17 is used to carry dust to the dust collector housing 1. The dust-free gas is put into the bag dust collector housing 1. The gas is below the mounting plate 2, and the gas passes through the dust bag 6 and the exhaust window 10 to enter the top of the mounting plate 2. In this process, the dust is filtered by the dust bag 6, so that the dust remains on the dust bag 6 or falls on the bottom of the bag dust collector housing 1. The dust-free gas is finally discharged through the exhaust pipe 18. The equipment needs regular maintenance. At this time, the dust bag 6 will be removed for cleaning or directly replaced with a new dust bag 6. When disassembling, first remove the side baffle 5 from the bag dust collector housing 1. The disassembly window 4 is exposed. At this time, the open end of the installation window 3 is connected to the disassembly window 4. The removable plate 7 can be slid out of the installation window 3 directly close to the disassembly window 4, so that the side slide plate 8 is disengaged from the installation slide groove 9, and the corresponding bag-type dust removal component can be removed, which is convenient for cleaning or replacement of the bag-type dust removal component. During installation, first slide the side slide plate 8 into the installation slide groove 9 corresponding to the installation slide groove 9 to slide the removable plate 7 into the installation window 3, and finally install the side baffle plate 5. The operation is simple, and quick installation and disassembly can be completed in a small space, thereby improving the efficiency of disassembly and assembly.

[0024] Embodiment 2

[0025] Based on the first embodiment, Figure 4As shown, a dust collecting hopper 19 is provided at the bottom of the bag dust collector housing 1, and a dust exhaust pipe 20 is connected to the bottom of the dust collecting hopper 19. A vibration mechanism is installed at the bottom of the bag dust collector housing 1, and the vibration mechanism is used to make the dust collecting hopper 19 vibrate, and the dust falling from the dust collecting bag 6 falls into the dust collecting hopper 19 and is discharged from the bag dust collector housing 1 through the dust exhaust pipe 20; the vibration mechanism includes a motor 21, a vibration plate 22 and a spring 23. A mounting vertical plate 24 is fixed to the bottom of the bag dust collector housing 1, one end of the vibration plate 22 is slidably penetrated on the mounting vertical plate 24, and a spring 23 is sleeved on the vibration plate 22, and the spring 23 is connected to the mounting vertical plate 24. The motor 21 is installed at the bottom of the bag dust collector housing 1, and the output shaft of the motor 21 is connected to an intermittent gear 25. A rack 26 is fixed to the top of the vibration plate 22, and the intermittent gear 25 meshes with the rack 26. In order to avoid dust in the bag dust collector The accumulation in the dust hopper 19 affects the dust discharge effect, and a vibration mechanism is added to prevent dust clogging. Specifically, the motor 21 mobilizes the rack 26 to move through the meshing of the intermittent gear 25 and the rack 26. Initially, the vibration plate 22 contacts the dust hopper 19, and the spring 23 is in a compressed state. The rack 26 drives the vibration plate 22 to move away from the dust hopper 19. When the toothed area of ​​the intermittent gear 25 is separated from the rack 26, the intermittent gear 25 is disengaged from the rack 26. At this time, the vibration plate 22 moves close to the dust hopper 19 under the reaction force of the spring 23, so that the vibration plate 22 hits the dust hopper 19, causing the dust hopper 19 to vibrate, thereby avoiding dust accumulation affecting dust discharge. The motor 21 continues to rotate, causing the vibration plate 22 to reciprocate and hit the dust hopper 19 to generate vibration. This vibration can also be transmitted to the bag dust collector housing 1, which helps to remove dust from the dust bag 6.

[0026] Furthermore, a pulse tube 16 is provided between two adjacent dust bags 6. A plurality of air holes are provided at the bottom of the pulse tube 16 along its own axial direction. The width of the dust bag 6 is greater than the width of the removable plate 7. A slot for installing the pulse tube 16 is provided through the mounting plate 2.

To facilitate the installation of the bag dust removal assembly, a wedge surface 12 is provided on the elastic sealing pad 11. During installation, first slide one end of the elastic sealing pad 11 with the wedge surface 12 into the installation slide groove 9, so that the side slide plate 8 can be easily inserted into the installation slide groove 9, and the elastic sealing pad 11 can be smoothly deformed and interference fit in the installation slide groove 9 through the guidance of the wedge surface 12, thereby completing the rapid installation of the bag dust removal assembly.
