[0002] Currently, baghouse dust collectors are a type of 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 dust-laden gas enters the baghouse dust collector, larger and heavier 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] Dust collector filter bags refer to the cloth bags used in dust collectors. In the production processes of thermal power generation, steel, coking, non-ferrous smelting and cement industries, a large amount of dust is generated, which causes serious environmental pollution. Therefore, the state has set strict requirements for the atmospheric emissions of these enterprises. Bag dust collection is a widely used and ideal dust collection method. The dust collection bag is called the heart of the bag dust collector and plays a very important role in the dust collection effect.

[0004] Conventional filter bags on the market accumulate a large amount of impurities on their surface after prolonged use. To ensure their proper functioning, these bags need to be disassembled and replaced, which is time-consuming and labor-intensive. Therefore, a new technical solution is needed to address this issue. A self-cleaning mechanism can clean the outer wall of the filter bag, significantly reducing the replacement cycle. Utility Model Content

[0021] Please see Figure 1-3 The present invention provides a technical solution: a dust removal filter bag, including a mounting base 1, a support cage 11 fixedly mounted on one side of the mounting base 1, a filter bag 13 sleeved on the outer wall of the support cage 11, and a self-cleaning mechanism mounted on the mounting base 1.

[0022] The self-cleaning mechanism includes a rotating groove 2 opened on the side wall of the mounting base 1, a slip ring 21 rotatably mounted in the rotating groove 2, a fixed base 22 fixedly mounted on one end of the side wall of the slip ring 21, a motor 23 fixedly mounted inside the fixed base 22, a gear 24 fixedly mounted on the shaft of the motor 23, a cleaning rod 26 fixedly mounted on the middle of the other end of the gear 24, and an internal gear ring 25 fixedly mounted on the outer side of one end of the mounting base 1. The internal gear ring 25 meshes with the gear 24, and the cleaning rod 26 corresponds to the side wall of the filter bag 13.

[0023] In this technical solution, the support cage 11 is positioned inside the dust filter by the mounting base 1. The filter bag 13 is then fitted onto the outside of the support cage 11 at the bottom of the mounting base 1. After the filter bag 13 has been used for a long time, the motor 23 inside the self-cleaning mechanism is driven, which can drive the gear 24 and the cleaning rod 26 to rotate. Since the gear 24 meshes with the internal gear ring 25 on the outside of the mounting base 1, the cleaning rod 26 can move along the direction of the internal gear ring 25 while rotating, which can efficiently clean the dust on the outer wall of the filter bag 13, greatly increasing the service life of the filter bag 13 and reducing the replacement cycle of the filter bag 13.

[0024] In some technical solutions, a cloth sleeve 3 is fitted to the bottom of the cleaning rod 26. Multiple sets of equally spaced cleaning brushes 31 are fixedly installed on the outer wall of the cloth sleeve 3. The multiple sets of cleaning brushes 31 correspond to the outer wall of the filter bag 13, which can efficiently clean the filter bag 13. A detachable ring 32 is fixedly installed at the port of the cloth sleeve 3. The detachable ring 32 is fixedly connected to the cleaning rod 26 by a second bolt, which facilitates the installation and removal of the cloth sleeve 3.

[0025] In this technical solution, after the cloth cover 3 is positioned on the outer wall of the cleaning rod 26 by the detachable ring 32, the cloth cover 3 is very convenient to install and remove, making it easy to replace the cloth cover 3 after long-term use. At the same time, with the multiple sets of cleaning brushes 31 installed on the outer wall of the cloth cover 3, the multiple sets of cleaning brushes 31 continuously rub the outer wall of the filter bag 13, which can further improve the cleaning efficiency of the cleaning rod 26 on the filter bag 13.

[0026] In some technical solutions, a collar is fixedly installed at the port of the filter bag 13.

When gas containing impurities is introduced into the filter, the multiple sets of filter bags 13 attached to the outside of the support cage 11 can filter particulate matter in the air, achieving a good dust removal effect. Simultaneously, the internal motor 23 of the self-cleaning mechanism drives the gear 24 and cleaning rod 26 to rotate. Since the gear 24 meshes with the internal gear ring 25 on the outside of the mounting base 1, the cleaning rod 26 can move along the direction of the internal gear ring 25 while rotating, efficiently cleaning the dust. The filter bag 13 filters dust and is cleaned, which greatly increases the service life of the filter bag 13 and reduces the replacement cycle of the filter bag 13. At the same time, multiple sets of equally spaced cleaning brushes 31 are fixedly installed on the outer wall of the cloth cover 3, and a detachable ring 32 is fixedly installed at the port of the cloth cover 3. When the cloth cover 3 is positioned on the outer wall of the cleaning rod 26 through the detachable ring 32, the cloth cover 3 is very convenient to install and remove, which makes it easy to replace the cloth cover 3 after long-term use. In addition, with the multiple sets of cleaning brushes 31 installed on the outer wall of the cloth cover 3, the multiple sets of cleaning brushes 31 continuously rub the outer wall of the filter bag 13, which can further improve the cleaning efficiency of the cleaning rod 26 on the filter bag 13.
