Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly filter bag technology, and in particular to an antistatic and high-pressure resistant environmentally friendly filter bag. Background Technology

[0002] Environmentally friendly filter bags are made of high-efficiency filter materials such as polyester fiber, polypropylene, and glass fiber, and can be customized according to specific application needs. They are widely used in industrial dust removal, air purification, and water treatment. When using environmentally friendly filter bags, it is necessary to improve their antistatic and high-pressure resistance to extend their service life.

[0003] A search of the Chinese patent "An Antistatic and High-Pressure Resistant Environmentally Friendly Filter Bag" (publication number CN217773556U) reveals that this patent incorporates an antistatic component to enhance the antistatic effect of the filter bag. The nylon layer effectively blocks airborne dust particles, while the polyethylene layer provides excellent wear resistance. Furthermore, the polyethylene resin layer further enhances the antistatic effect. This device improves the filter bag's antistatic performance through the combination of the antistatic polyethylene resin layer and the ion-conducting electrostatic mesh layer on the upper surface of the filter bag. The nylon and polyethylene layers work together to provide excellent wear resistance. However, when protecting the environmentally friendly filter bag, the difference between the antistatic polyethylene resin layer and the ion-conducting electrostatic mesh layer in a dry environment leads to insufficient static neutralization, affecting the filter bag's antistatic and high-pressure resistance. This makes it inconvenient to effectively protect the filter bag and reduces the device's overall effectiveness.

[0004] Therefore, an antistatic and high-pressure resistant environmentally friendly filter bag is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an antistatic and high-pressure resistant environmentally friendly filter bag to solve the above-mentioned problems, thereby improving the difficulty in effectively protecting the environmentally friendly filter bag.

[0006] This utility model achieves the above-mentioned objectives through the following technical solution: an antistatic and high-pressure resistant environmentally friendly filter bag, comprising a filter basket with a fixing ring installed at the top of the filter basket; a protective mechanism, which can improve the antistatic and high-pressure resistant effect of the environmentally friendly filter bag, is disposed on the inner wall of the filter basket; wherein, the protective mechanism includes a filter layer disposed in the filter basket, the outer wall of the filter layer is provided with a conductive coating, the outer wall of the conductive coating is provided with a polyurethane coating, the top of the filter layer is fixedly connected to the fixing ring, the filter layer is made of nylon, which can efficiently filter particulate matter, improve the wear resistance and corrosion resistance of the environmentally friendly filter bag, the conductive coating on the outer wall of the filter layer is made of polyether ester compound, which improves the static electricity neutralization efficiency, the polyurethane coating, the nylon, the conductive coating and the polyurethane coating can improve the tear resistance and deformation resistance of the environmentally friendly filter bag, and can also reduce the probability of delamination between the nylon and the conductive coating and the polyurethane coating, thereby improving the antistatic and high-pressure resistant effect of the environmentally friendly filter bag.

[0007] Preferably, the protective mechanism further includes a skeleton layer fixedly connected to the inner wall of the filter layer. The top end of the skeleton layer is fixedly connected to a fixing ring. The skeleton layer can improve the strength of the environmentally friendly filter bag and reduce its deformation.

[0008] Preferably, a protective layer is fixedly connected to the inner wall of the skeleton layer, and the top of the protective layer is connected to a fixing ring. The protective layer of the inner wall of the environmentally friendly filter bag is made of carbon fiber, which can improve the conductivity and mechanical strength of the filter bag, and improve the antistatic and high-pressure resistance of the filter bag.

[0009] Preferably, the inner wall of the fixing ring is fixedly connected with two retaining rings, and the top of the outer wall of the filter basket has two retaining grooves that fit into the retaining rings. The fixing ring connects the filter basket and the environmentally friendly filter bag together by the two retaining rings fitting into the retaining grooves.

[0010] Preferably, the inner wall of the fixing ring is fixedly connected with several evenly distributed support plates. The support plates inside the environmentally friendly filter bag can provide certain support to prevent the environmentally friendly filter bag from deforming during use.

[0011] Preferably, the outer wall of the support plate is attached to the inner wall of the protective layer.

[0012] Preferably, a handle is fixedly connected between the two support plates, and the handle is disposed on the inner wall of the fixing ring, so that the handle inside the environmentally friendly filter bag can be disassembled and removed.

[0013] The beneficial effects of this utility model are:

[0014] 1. By incorporating protective mechanisms, the filter layer inside the filter basket of the environmentally friendly filter bag is made of nylon, which can efficiently filter particulate matter and improve the wear resistance of the filter bag. The conductive coating on the outer wall of the filter layer is made of polyether ester compound, which can neutralize static electricity. The polyurethane coating on the outer wall of the filter layer can reduce the wear of the environmentally friendly filter bag by high-pressure airflow. The skeleton layer inside the environmentally friendly filter bag can support it and prevent the filter bag from deforming during use. The protective layer is made of carbon fiber, which can improve the conductivity and mechanical strength of the filter bag. The filter layer, conductive coating, and polyurethane coating can be bonded together through heat activation. The skeleton layer and protective layer are connected to the fixing ring and bonded to the nylon, which can improve the antistatic and high-pressure resistance of the environmentally friendly filter bag and improve the performance of the environmentally friendly filter bag.

[0015] 2. By setting up retaining rings, grooves, and support plates, when using the environmentally friendly filter bag, the filter bag can be installed in the filter basket by the two retaining rings on the inner wall of the fixing ring cooperating with the grooves. The two retaining rings are made of flexible material. When installed, the retaining rings deform and embed into the grooves. The support plate of the environmentally friendly filter bag can support it, so that the filter layer, skeleton layer, and protective layer can fit in close contact with the filter basket, improving the stability of the environmentally friendly filter bag and enhancing its high pressure resistance.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In practical implementation: such as Figure 1-4 As shown, an antistatic and high-pressure resistant environmentally friendly filter bag includes a filter basket 1 with a fixing ring 2 installed at the top. A protective mechanism 3, which can improve the antistatic and high-pressure resistant effect of the environmentally friendly filter bag, is disposed on the inner wall of the filter basket 1. The protective mechanism 3 includes a filter layer 301 disposed in the filter basket 1, a conductive coating 302 disposed on the outer wall of the filter layer 301, a polyurethane coating 303 disposed on the outer wall of the conductive coating 302, and the top of the filter layer 301 is fixedly connected to the fixing ring 2.

[0023] like Figure 2 As shown, the protective mechanism 3 also includes a skeleton layer 304 fixedly connected to the inner wall of the filter layer 301. The top end of the skeleton layer 304 is fixedly connected to the fixing ring 2. A protective layer 305 is fixedly connected to the inner wall of the skeleton layer 304. The top end of the protective layer 305 is connected to the fixing ring 2. When the environmentally friendly filter bag is in use, the filter layer 301 inside the environmentally friendly filter bag, together with the conductive coating 302 and the polyurethane coating 303, can improve the tear resistance and deformation resistance of the environmentally friendly filter bag. The conductive coating 302 and the polyurethane coating 303 together can enhance its strength in low-temperature environments. The polyurethane coating 303 together with the filter layer 301 can effectively improve the corrosion resistance of the environmentally friendly filter bag. The skeleton layer 304 can support the environmentally friendly filter bag and prevent it from deforming during use. The protective layer 305 can improve the conductivity and mechanical strength of the environmentally friendly filter bag, improve the antistatic and high-voltage resistance of the environmentally friendly filter bag, and improve the use effect of the environmentally friendly filter bag.

[0024] like Figure 3 and Figure 4 As shown, two retaining rings 306 are fixedly connected to the inner wall of the fixing ring 2. Two slots 307 that fit into the retaining rings 306 are opened at the top of the outer wall of the filter basket 1. Several evenly distributed support plates 308 are fixedly connected to the inner wall of the fixing ring 2. The outer wall of the support plate 308 is attached to the inner wall of the protective layer 305. A handle 309 is fixedly connected between two support plates 308. The handle 309 is set in the inner wall of the fixing ring 2. When the environmental protection filter bag is used, the support plate 308 in the fixing ring 2 can support and reinforce the environmental protection filter bag, improve the strength of the environmental protection filter bag, and the handle 309 can be used to pick up and install the environmental protection filter bag. The environmental protection filter bag can be stably installed by embedding it into the slots 307 through the two retaining rings 306 in the fixing ring 2, which can improve the use effect of the environmental protection filter bag and improve the strength and stability of the environmental protection filter bag.

[0025] In use, the handle 309 is manually picked up to engage the fixing ring 2 onto the filter basket 1 to install the environmentally friendly filter bag. The two retaining rings 306 on the inner wall of the fixing ring 2 deform under pressure, and the retaining rings 306 fit into the retaining groove 307 to install and fix the filter bag. When the environmentally friendly filter bag is in use, the filter layer 301 on the outer wall of the filter bag can efficiently filter particulate matter and improve the wear resistance of the filter bag. The conductive coating 302 on the outer wall of the filter layer 301 reduces the surface resistivity of the filter bag to a safe range (≤10^9Ω) by absorbing ambient moisture, thereby enhancing the electrostatic neutralization efficiency of the filter bag. The polyurethane coating 303 on the outer wall of the filter layer 301 can reduce the wear of the filter bag by high-pressure airflow. The skeleton layer 304 can support the filter bag. The protective layer 305 can improve the mechanical strength and conductivity of the filter bag. The support plate 308 inside the filter bag can make the filter bag fit against the inner wall of the filter basket 1.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
