Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial dust removal technology, specifically to an environmentally friendly dust removal filter bag that is pressure-resistant and tear-resistant. Background Technology
[0002] In the field of industrial dust removal, environmentally friendly dust collector filter bags are core filtration components, and their performance directly affects dust removal efficiency and equipment operational stability. However, existing dust collector filter bags have certain problems in practical use:
[0003] On the one hand, negative pressure in the working environment can easily cause filter bags to collapse and deform, rendering their filtration function ineffective. On the other hand, the scouring of dust particles and the external pulling force during the collection process can easily cause filter bags to tear and break, shortening their service life. In addition, the lack of an effective pressure monitoring and control mechanism makes it impossible to respond to sudden pressure changes in a timely manner, leading to irreversible damage to the filter bags caused by local high pressure.
[0004] To address these issues, this invention provides an environmentally friendly dust collector filter bag that is pressure-resistant and tear-resistant. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an environmentally friendly dust collector filter bag that is pressure-resistant and tear-resistant, thus solving the aforementioned problems.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure-resistant and tear-resistant environmentally friendly dust collector filter bag, comprising a filter bag body, an auxiliary component provided on the outside of the filter bag body, the filter bag body including an inner support layer, a filter layer fixedly installed on the outside of the inner support layer, a pressure-resistant and tear-resistant layer fixedly installed on the outside of the filter layer, and an outer protective layer fixedly installed on the outside of the pressure-resistant and tear-resistant layer.
[0007] Preferably, the inner support layer is made of rigid plastic mesh.
[0008] Preferably, the filter layer is made of polytetrafluoroethylene membrane filter material.
[0009] Preferably, the compression-resistant and tear-resistant layer is made of high-strength aramid fibers woven into a mesh and then coated with high-strength rubber.
[0010] Preferably, the outer protective layer is made of polyester fiber coating material.
[0011] Preferably, the auxiliary component includes a main block and an exhaust pipe. The main block is fixedly installed inside the upper part of the filter bag body, and the exhaust pipe is fixedly installed inside the lower part of the filter bag body. A pressure sensor is fixedly installed on the inner side of the main block, and the pressure sensor is located inside the filter bag body.

[0012] Preferably, a control system is fixedly installed inside the main body block, and the control system is electrically connected to the pressure sensor and the pressure relief valve.
[0013] Beneficial effects
[0014] This utility model provides an environmentally friendly dust collector filter bag that is resistant to pressure and tearing. Compared with the prior art, it has the following advantages:
[0015] 1. This pressure-resistant and tear-resistant environmentally friendly dust collector filter bag features a scientifically designed multi-layer structure. The inner support layer is made of rigid plastic mesh, providing stable support for the filter bag and effectively preventing collapse under negative pressure while dispersing pressure. The pressure-resistant and tear-resistant layer uses high-strength aramid fiber woven mesh coated with high-strength rubber, combining the advantages of high strength and high modulus of aramid fiber with the elasticity and flexibility of rubber. This allows it to resist external pulling and pressure impacts, improving the filter bag's pressure and tear resistance, extending its service life, and reducing equipment maintenance costs.
[0016] 2. This pressure-resistant and tear-resistant environmentally friendly dust collector filter bag has a pressure sensor in the auxiliary components that monitors the internal pressure of the filter bag in real time. The control system activates the pressure relief valve in time to release air and reduce pressure when the pressure exceeds the threshold based on the pressure sensor data, effectively preventing damage to the filter bag due to excessive pressure.

[0023] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] Reference Figures 1 to 3 This application provides an environmentally friendly dust collector filter bag that is resistant to pressure and tearing, including a filter bag body 1. An auxiliary component 2 is provided on the outside of the filter bag body 1. The filter bag body 1 includes an inner support layer 11. A filter layer 12 is fixedly installed on the outside of the inner support layer 11. A pressure-resistant and tear-resistant layer 13 is fixedly installed on the outside of the filter layer 12. An outer protective layer 14 is fixedly installed on the outside of the pressure-resistant and tear-resistant layer 13.
[0025] In an optional embodiment, the inner support layer 11 is made of rigid plastic mesh.
[0026] It should be noted that the rigid plastic mesh provides stable support for the filter bag, preventing it from collapsing under negative pressure and dispersing the pressure.
[0027] In an optional embodiment, the filter layer 12 is made of polytetrafluoroethylene (PTFE) membrane filter media.
[0028] It should be noted that the extremely low surface energy of polytetrafluoroethylene (PTFE) enables low dust adhesion and high-precision filtration.
[0029] In an optional embodiment: the compression-resistant and tear-resistant layer 13 is made of high-strength aramid fibers woven into a mesh and then coated with high-strength rubber.
[0030] It should be noted that the high strength and high modulus of aramid fiber are combined with the elasticity and flexibility of rubber to resist external pulling and pressure impact.
[0031] In an optional embodiment, the outer protective layer 14 is made of a polyester fiber coated material.
[0032] It should be noted that the polyester fiber coating protects the internal structure and extends the filter bag's lifespan.
[0033] In an optional embodiment: the auxiliary component 2 includes a main body block 21 and an exhaust pipe 22. The main body block 21 is fixedly installed inside the upper part of the filter bag body 1, and the exhaust pipe 22 is fixedly installed inside the lower part of the filter bag body 1. A pressure sensor 24 is fixedly installed inside the main body block 21, and the pressure sensor 24 is located inside the filter bag body 1. A pressure relief valve 23 is fixedly installed inside the exhaust pipe 22, and a filter screen 25 is fixedly installed at the inner end of the exhaust pipe 22. A control system is fixedly installed inside the main body block 21, and the control system is electrically connected to the pressure sensor 24 and the pressure relief valve 23.
[0034] It should be noted that the pressure sensor 24 is installed near the air inlet inside the filter bag to monitor the pressure in real time; the control system receives the data from the pressure sensor 24 and starts when the pressure exceeds the threshold; the control pressure relief valve 23 opens to release and reduce pressure, and the filter screen 26 is used to prevent secondary pollution; the exhaust pipe 22 is located at the bottom or side of the filter bag to help achieve pressure balance and reduce local high pressure damage.
[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0036] Working Principle: The control system uses a Siemens S7-200SMART series PLC, the pressure sensor 24 is an MBS3000 diffused silicon pressure sensor, and the pressure relief valve 23 is a self-operated micro-opening spring safety valve A27H-16C. During operation, the pressure sensor 24 (MBS3000 type) installed near the air inlet inside the filter bag body 1 monitors the internal pressure of the filter bag in real time and converts the pressure signal into an electrical signal, which is transmitted to the control system (Siemens S7-200SMART series PLC) in the main body block 21. When the pressure data received by the control system exceeds the preset threshold, it immediately issues a command to control the pressure relief valve 23 (self-operated micro-opening spring safety valve A27H-16C) in the exhaust pipe 22 to open, allowing the gas in the filter bag to be discharged through the exhaust pipe 22, thus reducing pressure. During this process, the filter screen 25 at the inner end of the exhaust pipe 22 effectively intercepts dust and prevents secondary pollution, thereby ensuring that the filter bag body 1 operates in a stable pressure environment.
[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
[0038] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
