Description

Technical Field

[0001] The utility model relates to the technical field of corrosion resistance of dustproof filter bags, in particular to a corrosion-resistant dust removal filter bag. Background Art

[0002] The dust filter bag is a highly efficient dust filter material. The dust filter bag is made of polyester staple fiber, PPS fiber, PP polypropylene, aramid fiber, and nylon fiber. The service life is generally 2 to 4 years. It has good air permeability, high dust collection rate, and is easy to clean. The dust filter bag is mainly set in the bag dust collector. The main bag dust collector is mainly used to control air pollution. The working principle of this dust collector is to use the filtering function of the dust filter bag to capture the dust particles in the dust-containing gas, so as to achieve the purpose of purifying the air. The dust filter bag needs to have certain corrosion resistance during the dust removal process.

[0003] For example, the Chinese patent "A dust filter bag resistant to high temperature, high strength and strong corrosion" with announcement number CN218188478U includes a dust removal layer, a port cloth belt and a flexible cloth layer. The inner side of the dust removal layer is fixedly connected to a heat-conducting carbon fiber layer, the inner side of the heat-conducting carbon fiber layer is fixedly connected to a chemical reaction layer, the inner side of the chemical reaction layer is fixedly connected to a corrosion-resistant coating, the outer side of the dust removal layer is fixedly connected to a metal braided layer, the upper end of the dust removal layer is fixedly connected to a port cloth belt, the outer side of the port cloth belt is fixedly connected to an elastic clip, the inner side of the elastic clip is slidably connected to an elastic rack, and the outer side of the elastic rack is fixedly connected to a metal braided layer. A side sliding connection is provided with a limit frame, the inner side of the limit frame is rotatably connected with a limit clamping plate, the limit clamping plate is meshingly connected with the elastic rack, the outer side of the metal braided layer is fixedly connected with a flexible cloth layer, the inner side of the port cloth belt is fixedly connected with an elastic cloth belt, a filter port is provided on the inner side of the corrosion-resistant coating, and the filter ports are arranged at equal intervals, a spring is fixedly connected to the inner side of the limit clamping plate, the spring is fixedly connected to the limit frame, a clamping tooth is fixedly connected to the outer side of the elastic rack, the metal braided layer is made of flexible metal material, there are two elastic clamping strips, and the elastic clamping strips are symmetrically arranged about the central axis of the flexible cloth layer.

[0004] Although the above-mentioned prior art can achieve corrosion resistance for the bag body, in actual use, on the one hand, the air flow that transports dust usually contains a certain amount of moisture. When dust removal is performed, the moisture is easy to combine with dust particles to cause the dust to agglomerate, resulting in the agglomerated dust adhering to the inside and outside of the bag body during the dust removal process and clogging the filter screen on the bag body, thereby reducing the dust removal efficiency. On the other hand, the bag body is not flexible enough in disassembly and assembly. When the bag body needs to be replaced after a period of use, the fixing device of the bag body needs to be removed and then taken down, which increases the workload of the operator and further affects the efficiency of the filtering operation. Therefore, it does not meet the existing needs. In this regard, we have proposed a corrosion-resistant bag body. Utility Model Content

[0005] The purpose of the present utility model is to provide a corrosion-resistant dust removal filter bag, so as to solve the problems raised in the above-mentioned background technology. Usually, the airflow transporting dust contains a certain amount of moisture. When dust removal is carried out, the moisture easily combines with dust particles to cause the dust to cake. As a result, the caked dust will adhere to the inside and outside of the bag body and block the filter screen on the bag body during the dust removal process. In addition, the disassembly and assembly of the bag body are not flexible enough. When the bag body needs to be replaced after being used for a period of time, the fixing device of the bag body needs to be removed before the bag body can be taken off, which increases the workload of the operator.

[0006] To achieve the above purpose, the present utility model provides the following technical solutions: A corrosion-resistant dust removal filter bag, including a bag body, corrosion-resistant layers are arranged on both the inner and outer sides of the bag body, and the corrosion-resistant layers are connected to the bag body by hot pressing; It also includes:

[0007] An anti-static coating, which is arranged inside the corrosion-resistant layer that fits the inner and outer sides of the bag body, and the anti-static coating is connected to the bag body by hot pressing.

[0008] Preferably, a waterproof coating is arranged inside the corrosion-resistant layer on the outer side of the anti-static coating, and the waterproof coating is connected to the anti-static coating by hot pressing.

[0009] Preferably, an anti-corrosion coating is arranged inside the corrosion-resistant layer on the outer side of the waterproof coating, and the anti-corrosion coating is connected to the waterproof coating by hot pressing.

[0010] Preferably, a fixing block is arranged at the upper end of the bag body, and the fixing block is fixedly connected to the bag body.

[0011] Preferably, an installation plate is arranged at the lower end of the fixing block, and the installation plate is fixedly connected to the fixing block. An annular magnet is arranged at the lower end of the installation plate, and the annular magnet is fixedly connected to the installation plate.

[0012] Preferably, a sealing strip is arranged at the lower end of the fixing block between the annular magnet and the bag body, and the sealing strip is fixedly connected to the fixing block.

[0013] Preferably, a configuration block is arranged at the lower end of the bag body, and the configuration block is fixedly connected to the bag body.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. The utility model can make the bag body corrosion-resistant, waterproof and anti-static by setting an anti-corrosion layer. When performing dust removal and filtration, when the airflow containing dust is transported into the bag body, the airflow is discharged after passing through the bag body. When the airflow passes through the bag body, it first passes through the anti-corrosion coating, then through the waterproof coating, and finally through the anti-static coating into the interior of the bag body. At this time, the dust in the airflow is blocked by the bag body and the dust gathers together for centralized recovery and treatment by the operator. The anti-corrosion coating can prevent the bag body from being damaged by corrosive dust and extend the service life of the bag body. The waterproof coating can prevent the moisture in the airflow from causing the dust to cake and adhere to the bag body, and the anti-static coating can prevent the bag body from generating a large amount of static electricity due to the friction and collision of the dust with the pipe wall, etc. when passing through the pipeline.

[0016] 2. The utility model can quickly disassemble and assemble the bag body through the annular magnet and the fixing block. When disassembling the bag body, after opening the dust removal box, at this time, grasp the fixing block and lift it upward to separate the annular magnet of the fixing block on the bag body from the fixing structure adsorbed thereto, and continue to move upward until the fixing block is removed from the interior of the dust removal box together with the bag body. When installing a new bag body, first put the lower end of the bag body into the dust removal box, and then fix the fixing block by magnetically adsorbing the annular magnet on the fixing block through the fixing structure, so that the bag body is completed for installation, simplifying the disassembly and assembly process of the bag body, thereby facilitating the operator to disassemble and assemble the bag body.

[0017] 3. The utility model can increase the weight of the lower end of the bag body by setting a configuration block. When the installation of the bag body is completed, at this time, the bag body is fixed in the dust removal box, and at this time, the bag body and the configuration block are in a natural hanging state due to their own gravity. The configuration block increases the gravity of the lower end of the bag body, making the bag body in a straightened state, which can prevent the airflow from blowing the bag body and making the bag body flutter during the dust removal process, thereby improving the dust removal effect.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] Please refer to Figures 1-4 , an embodiment provided by the present utility model: a corrosion-resistant dust filter bag, including a bag body 1, corrosion-resistant layers 2 are provided on both the inner and outer sides of the bag body 1, and the corrosion-resistant layers 2 are connected to the bag body 1 by hot pressing; further including:

[0025] An anti-static coating 203, which is provided inside the corrosion-resistant layer 2 that fits the inner and outer sides of the bag body 1, and the anti-static coating 203 is connected to the bag body 1 by hot pressing.

[0026] During use, when dust removal and filtration are performed, when the airflow containing dust is transported to the inside of the bag body 1, the airflow passes through the bag body 1 and then is discharged. When the airflow passes through the bag body 1, it first passes through the anti-corrosion coating 201, then through the waterproof coating 202, and finally through the anti-static coating 203 and enters the inside of the bag body 1. At this time, the dust in the airflow is blocked by the bag body 1 and the dust gathers together for centralized recovery and treatment by the operator. The anti-corrosion coating 201 can prevent the bag body 1 from being damaged by corrosive dust, extending the service life of the bag body 1. The waterproof coating 202 can prevent the situation where dust caking and adhering to the bag body 1 when the dust encounters the damp bag body 1, and the anti-static coating 203 can prevent the bag body 1 from generating a large amount of static electricity due to the dust rubbing and colliding with the pipe wall, etc. when passing through the pipeline.

[0027] Please refer to Figure 3 , a waterproof coating 202 is provided inside the corrosion-resistant layer 2 on the outer side of the anti-static coating 203, and the waterproof coating 202 is connected to the anti-static coating 203 by hot pressing, which can prevent the situation where dust caking and adhering to the bag body 1 when the dust encounters the damp bag body 1.

[0028] Please refer to Figure 1 , an anti-corrosion coating 201 is provided inside the corrosion-resistant layer 2 on the outer side of the waterproof coating 202, and the anti-corrosion coating 201 is connected to the waterproof coating 202 by hot pressing, improving the corrosion resistance of the bag body 1 and avoiding damage to the bag body 1 caused by contact between the corrosive dust and the bag body 1, thereby extending the service life of the bag body 1.

[0029] Please refer to Figure 1 , a fixing block 3 is provided at the upper end of the bag body 1, and the fixing block 3 is fixedly connected to the bag body 1, facilitating the fixing of the bag body 1 in the dust removal box through the fixing block 3.

[0030] Please refer to Figure 1 andFigure 2 , an installation plate 5 is provided at the lower end of the fixed block 3, and the installation plate 5 is fixedly connected to the fixed block 3. An annular magnet 6 is provided at the lower end of the installation plate 5, and the annular magnet 6 is fixedly connected to the installation plate 5. The fixed block 3 can be magnetically adsorbed on the fixed structure inside the dust removal box through the annular magnet 6. When the bag body 1 needs to be disassembled or assembled, directly pull or squeeze the fixed block 3 to enable quick disassembly and assembly of the fixed block 3.

[0031] Please refer to Figure 2 and Figure 4 , a sealing strip 7 is provided at the lower end of the fixed block 3 between the annular magnet 6 and the bag body 1, and the sealing strip 7 is fixedly connected to the fixed block 3. Through the sealing strip 7, the sealing performance between the fixed block 3 and the fixed structure of the dust removal box can be enhanced, avoiding dust overflowing through the gap between the fixed block 3 and the fixed structure of the dust removal box during the dust removal process.

[0032] Please refer to Figure 1 , a configuration block 4 is provided at the lower end of the bag body 1, and the configuration block 4 is fixedly connected to the bag body 1, increasing the weight of the bag body 1 and making the bag body 1 in a state of natural drooping and straightening, thereby improving the dust removal effect.

[0033] Working principle: When the bag body 1 is to be removed, after opening the dust removal box, at this time, grasp the fixed block 3 and lift it upward, so that the annular magnet 6 of the fixed block 3 on the bag body 1 is separated from the fixed structure to which it is adsorbed and installed. Continue to move upward until the fixed block 3 is removed from the inside of the dust removal box together with the bag body 1. When a new bag body 1 is to be installed, first place the lower end of the bag body 1 into the dust removal box, and then fix the fixed block 3 by magnetic adsorption of the annular magnet 6 on the fixed block 3 through the fixed structure, so that the bag body 1 is installed. The disassembly and assembly process of the bag body 1 is simplified, facilitating the operator to disassemble and assemble the bag body 1. When the installation of the bag body 1 is completed, at this time, the bag body 1 is fixed in the dust removal box. At this time, the bag body 1 and the configuration block 4 are in a state of natural drooping due to their own gravity. The configuration block 4 increases the gravity at the lower end of the bag body 1, making the bag body 1 in a straightened state, which can avoid the bag body 1 fluttering due to the airflow blowing during the dust removal process, thereby improving the dust removal effect.
