Description

Technical Field

[0001] This utility model relates to the field of filter bag technology, and in particular to a filter bag that is easy to fix. Background Technology

[0002] In the 19th century, with the advancement of the Industrial Revolution, the demand for filtration of liquids and gases in industrial production gradually increased. In the chemical, pharmaceutical, and food processing industries, there was a need to remove impurities from raw materials and separate specific components. This spurred the development of filter bag technology. The initial filter bag material was natural fiber, and the filtration performance of the filter bags at that time was limited, but it already played a certain role under the industrial conditions of the time. In the mid-20th century, global environmental problems became increasingly prominent, and the requirements for pollution control in industrial production became increasingly stringent. Baghouse dust collectors, as an effective air pollution control device, emerged, and filter bags, as the core component of baghouse dust collectors, also experienced rapid technological development. Synthetic fiber materials began to be widely used in filter bag manufacturing, as they have better chemical stability, corrosion resistance, and strength, greatly improving the performance of filter bags.

[0003] A search revealed Chinese Patent Publication No. CN216986748U, which discloses a wear-resistant double-layer filter bag. The outer side of the filter bag is sewn with an outer reinforcing mesh via sewing thread a, which includes horizontal strips a and vertical strips a. The inner side of the filter bag is sewn with an inner reinforcing mesh via sewing thread b, which also includes horizontal strips b and vertical strips b. The inner sides of the upper and lower ends of the filter bag are sewn with an opening ring via sewing thread c. A flexible protective sleeve is sewn with a sewing thread d on the outer side of the opening ring. The flexible protective sleeve includes a wrapping fabric and an inner cotton layer, with the inner cotton filling the inner side of the wrapping fabric. Several flow guides are sewn onto the sides of the outer reinforcing mesh via sewing thread e. Each flow guide includes a fixing block and a flow guide block. The flow guide block is located on the side of the fixing block, and the fixing block and flow guide block are integrally formed. Several stitching holes are provided on the side of the end of the fixing block. The use of flow guides and inner and outer reinforcing mesh improves the wear resistance of the filter bags, and the flexible protective sleeve enhances installation safety. However, if the filter bags are not properly secured, exhaust gas will pass directly through the gaps between the filter bags and the equipment without being filtered by the filter bags. This will result in a large amount of pollutants being released into the atmosphere. At the same time, if the filter bags shake or shift within the equipment, some filtration areas will be blocked and unable to function properly, reducing the effective filtration area. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a filter bag that is easy to fix, aiming to improve the existing technology where the filter bag is not properly fixed, and exhaust gas passes directly through the gap between the filter bag and the equipment without being filtered by the filter bag. This results in a large amount of pollutants being emitted into the atmosphere.

[0029] 1. In this utility model, the protrusion on the left side of the inner fixing ring 2 of the outer layer of the filter bag is first engaged and fixed with the fixing sleeve on the right side of the support plate. Then, the knob is turned. Since the gear meshes with the short strip 1, the L-shaped plate will slide along the inner side of the fixing block 2, so that the buckle engages with the fixing block 1, thus completing the fixed connection of the filter bag and the air filter. When the air filter and the filter bag are properly fixed, air can be effectively prevented from bypassing the filter medium, and the filter or filter bag can be prevented from shifting or deforming during operation.

A short strip 23 is rotatably connected to the inner side of the block 24. An anti-slip sleeve 16 is fixedly connected to the outer wall of the knob 15.

When the air filter 7 and the filter bag are correctly fixed, it can effectively prevent air from bypassing the filter medium and prevent the filter or filter bag from shifting or deforming during operation, thereby ensuring its complete filtration area, preventing the risk of falling off, and also preventing the entry of foreign objects.

[0048] When the pleats 201 increase the adsorption surface, the activated carbon 202 supported by the support 203 can play an adsorption role. The inner layer 205 of the filter bag outer layer 1 and inner layer of the filter bag play a double-layer filtration role. At the same time, the filter screen 204 behind the activated carbon 202 can further improve the filtration effect. In this way, when the air flows through the filter bag, it can pass through the activated carbon 202 and the filter screen 204 at the same time. It can not only filter out particulate matter in the air, but also adsorb harmful gases. The multi-layer structure of the outer layer is a fiber material used to intercept large dust particles, while the inner layer is a finer filter material used to capture tiny particles. When the air first passes through the pleats 201 for filtration, then enters the activated carbon 202 to adsorb harmful gases, and finally is further purified by the filter screen 204, the filtration advantages of different materials are fully utilized.
