Description

Technical Field

[0001] The utility model relates to the technical field of dust removal filter bags, and more specifically, to an antistatic dust removal filter bag. Background Art

[0002] In existing dust removal equipment, anti-static dust filter bags are a common filtering device used to capture and filter dust to prevent it from being discharged into the environment. However, the widely used method of fixing filter bags is mainly through bolt connection, which has certain shortcomings. Operators need to use tools, such as wrenches or screwdrivers, to insert the bolts one by one into the screw holes on the flange of the filter bag and tighten them one by one. This process is not only time-consuming and labor-intensive, but also makes the installation and removal of bolts more difficult in narrow or high spaces that are difficult to operate. In addition, after long-term use, bolts and nuts are prone to rust and corrosion, which makes it difficult to loosen the bolts when replacing the filter bag, and even requires cutting the filter bag to remove it, which undoubtedly increases the difficulty and cost of maintenance.

[0003] The inconvenience of bolt fixing seriously affects the use and maintenance efficiency of dust filter bags. In practical applications, filter bags need to be replaced regularly to ensure the normal operation of dust removal equipment. If each replacement requires a lot of time and effort to deal with bolt connections, it will not only extend the downtime of the equipment and affect the production progress, but also increase the workload of maintenance personnel. Especially in some large dust removal equipment, the number of filter bags may be as high as dozens or even hundreds, and the workload of bolt installation and removal will be very huge. In addition, due to the inconvenience of bolt fixing, some maintenance personnel may choose to extend the use cycle of the filter bag, resulting in excessive use of the filter bag and affecting the dust removal effect. Therefore, in order to improve the convenience of use of dust filter bags and reduce maintenance costs, a more efficient and quick filter bag fixing method is urgently needed to replace the traditional bolt connection.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides an anti-static dust filter bag with the following features:

[0017] Beneficial effects:

[0018] 1. The design of the disassembly mechanism cleverly solves the inconvenience of the traditional bolt fixing method. By installing multiple one-way sheets at equal distances on the inner wall of the fixing sleeve and setting springs and elastic strips on the one-way sheets, the filter bag body can be quickly installed and disassembled. When the filter bag body is inserted into the fixing sleeve, the one-way sheet is automatically tightened and stuck into the groove of the filter bag body under the action of the spring to complete the fixation; when disassembling, only the elastic strip needs to be pulled to drive the one-way sheet to move and release the filter bag body. This mechanism is simple to operate, saves time and effort, greatly improves the efficiency of filter bag replacement, and reduces maintenance costs. At the same time, the design of the bottom plate and the expansion tube can not only support the filter bag, but also adapt to the filter bag through the expansion and contraction of the compensation tube, thereby enhancing versatility.

[0019] 2. The unlocking mechanism adopts the coordinated design of telescopic plate and telescopic disc, which further optimizes the disassembly process of filter bag. The variable diameter blocks arranged equidistantly on the telescopic disc engage with the variable diameter groove on the telescopic plate. By rotating the telescopic disc, the telescopic movement of the telescopic plate can be controlled. When the filter bag needs to be removed, the two symmetrically arranged telescopic discs are rotated, and the variable diameter blocks are pushed into the variable diameter groove to push the telescopic plate outward, thereby pulling the elastic strip and the one-way sheet to release the engagement between the one-way sheet and the filter bag body, thereby realizing the rapid disassembly of the filter bag. This unlocking mechanism has a compact structure and is easy to operate. It avoids the damage that may be caused by directly pulling the elastic strip, and improves the reliability and service life of the dust removal equipment.

[0020] 3. The design of the conductive mechanism fully considers the particularity of the use environment of the dust filter bag, and solves the safety hazards caused by static electricity accumulation. By connecting a wire between the filter bag body and the fixed sleeve, and electrically connecting the wire to the conductive disk threaded on the fixed sleeve, and then connecting it to the external ground wire through the external wire on the side wall of the conductive disk, a complete static electricity release path is formed. During use, the static charge accumulated in the filter bag body can be transferred to the conductive disk and the external wire through the wire, and finally released to the ground wire, effectively preventing static electricity accumulation from causing sparks or explosions. At the same time, the conductive disk adopts a threaded connection method, which is easy to install and replace, and the threaded pipe on the fixed sleeve can be easily connected to external equipment, which improves the applicability and installation flexibility of the dust filter bag.

[0034] In summary, when the overall equipment is in use or running: when fixing, firstly, the expansion tube 5 is sleeved in the filter bag body 2.
