Description

Technical Field

[0001] The utility model relates to the technical field of composite filter bags, and particularly relates to a composite filter bag with anti-static and waterproof functions. Background Art

[0002] The filter bag is a key part in the operation of a bag-type dust collector. Usually, the cylindrical filter bag is vertically suspended in the dust collector, which can filter dust and has the function of facilitating dust stripping. The composite filter bag has high filtration performance and can effectively capture and filter particulate matter in the air, ensuring that the emission cleanliness meets the national standards. The composite filter bag is widely used in many industrial fields, including chemical industry, electric power, cement, iron and steel metallurgy and other industries.

[0003] In some industrial fields, such as semiconductor manufacturing and electronic equipment assembly, static electricity may trigger safety accidents such as fires and explosions in the existing composite filter bags. Moreover, when the filter bag is dealing with humid gas or liquid, moisture may penetrate into the interior through the filter bag, which not only causes the filter material to be damp, moldy or even damaged, but also the moisture will cause the filter bag to be blocked, reducing the filtration efficiency. Therefore, the filter bag needs to have anti-static and waterproof functions.

[0004] For example, a composite filter bag disclosed in the patent with the publication number CN214551911U is convenient to use. The composite filter bag in this patent does not have anti-static and waterproof functions. The filter bag without anti-static function cannot effectively prevent the generation and accumulation of static electricity, increasing these safety risks. Especially when dealing with flammable and explosive substances, the filter bag without anti-static function may become a potential safety hazard. Moreover, the filter bag without waterproof function cannot effectively prevent the penetration of moisture, thus shortening the service life of the filter bag. Therefore, the composite filter bag without anti-static and waterproof functions may have deficiencies in terms of safety, filtration effect, service life, application range, environmental protection and energy conservation.

[0005] Therefore, it is necessary to invent a composite filter bag with anti-static and waterproof functions to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a composite filter bag with anti-static and waterproof functions to solve the problem that the technology does not have anti-static and waterproof functions.

[0007] To achieve the above object, the present utility model provides the following technical solution: A composite filter bag with anti-static and waterproof functions, comprising a filter bag body, a cage, a bag mouth connection end and a fixing cover. A cage is arranged inside the filter bag body. The top end of the filter bag body is fixedly connected with a bag mouth connection end. A fixing cover is arranged on the top of the cage. An anti-slip pin is fixedly installed on the inner wall of the top end of the fixing cover. A fixing bolt is arranged on the side wall of the fixing cover. A screw hole is opened at the contact position between the fixing bolt and the fixing cover. The filter bag body is composed of a base cloth layer, a conductive wire mesh layer, a conductive fiber mesh layer, a first waterproof and breathable membrane and a second waterproof and breathable membrane.

[0008] Preferably, the bag mouth connection end covers the top end of the cage, and the bag mouth connection end and the top of the cage are snap-fitted with a fixing cover. Through the tight snap-fitting of the fixing cover, not only the overall structural stability of the filter bag is enhanced, but also the installation and disassembly are facilitated.

[0009] Preferably, a groove is opened at the bottom end of the fixing cover. The groove is arranged outside the bag mouth connection end, and the inner wall of the groove is closely attached to the outer wall of the bag mouth connection end. The design of the groove is to increase the contact area between the fixing cover and the bag mouth connection end, thereby enhancing the sealing performance and stability between the two.

[0010] Preferably, the anti-slip pins are arranged at the top ends of the bag mouth connection end and the cage. There are multiple anti-slip pins, and the multiple anti-slip pins are evenly distributed in a circular array. The multiple anti-slip pins can ensure uniform fixing force in multiple directions, further enhancing the stability and safety of the filter bag body.

[0011] Preferably, the fixing bolt and the screw hole are in threaded connection, and there are 4 fixing bolts and screw holes. The fixing bolts can firmly connect the fixing cover with the bag mouth connection end and the cage together.

[0012] Preferably, the base cloth layer is arranged in the middle. A conductive wire mesh layer is arranged on one side of the base cloth layer, and a conductive fiber mesh layer is arranged on the other side of the base cloth layer. The base cloth layer serves as the basic layer, providing the basic structure and strength of the filter bag. The conductive wire mesh layer and the conductive fiber mesh layer are used to achieve the anti-static function, ensuring the safe use of the filter bag in a specific environment.

[0013] Preferably, a first waterproof and breathable membrane is arranged on one side of the conductive wire mesh layer, and a second waterproof and breathable membrane is arranged on one side of the conductive fiber mesh layer. The first waterproof and breathable membrane is arranged on the inner side of the filter bag body, and the second waterproof and breathable membrane is arranged on the outer side of the filter bag body. The first waterproof and breathable membrane and the second waterproof and breathable membrane ensure that the filter bag body has good air permeability while being waterproof.

[0014] Preferably, the base fabric layer, the conductive mesh layer, the conductive fiber web layer, the first waterproof and breathable membrane, and the second waterproof and breathable membrane are fixedly connected by sewing, which can ensure the tightness and stability between the layers.

[0015] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0016] 1. Through the setting of the fixing cover and the fixing bolt, the bag mouth connection end at the top of the filter bag body covers the top of the cage, and the fixing cover ensures that the bag mouth connection end can completely cover and closely fit the top of the cage, forming a stable connection structure. Moreover, the anti-slip pin can be inserted into the material of the bag mouth connection end, and by means of physical biting, it can prevent the filter bag body from slipping or displacing when subjected to external force. Finally, by tightening the fixing bolt, the fixing cover and the bag mouth connection end can be further fixed, achieving the effect of limit fixation and effectively improving the firmness of the installation of the filter bag body.

[0017] 2. Through the setting of the conductive mesh layer, the conductive fiber web layer, the first waterproof and breathable membrane, and the second waterproof and breathable membrane, the conductive yarn layer and the conductive fiber layer are respectively arranged on both sides of the base fabric layer to form a conductive network, which helps to release or conduct static electricity, prevent static electricity from accumulating inside the filter bag, significantly improve the anti-static performance of the filter bag, and reduce the safety risks caused by static electricity accumulation. At the same time, the first waterproof and breathable membrane and the second waterproof and breathable membrane can block liquid water from entering the filter bag interior, while allowing water vapor to pass through, thereby keeping the inside of the filter bag dry, protecting the filter bag from the erosion of the external environment, and extending the service life of the filter bag.
