Description

Technical Field

[0001] This utility model belongs to the technical field of dust collector filter bags, specifically relating to a multi-layer composite dust collector filter bag. Background Technology

[0002] Dust collector filter bags, also known as dust collection bags, dust bags, or dust accumulation bags, are a crucial component in the operation of baghouse dust collectors. They are widely used in dust control in industries such as power, steel, cement, and chemicals. Their performance directly affects the dust collection efficiency and operational stability of the dust collector, enabling them to capture dust particles as small as a few micrometers, ensuring that the dust concentration in the emitted gas is far below emission standards.

[0003] Existing dust collector filter bags are used in high-temperature environments. High temperatures cause changes in the fiber structure of the filter bags, resulting in changes in the shape and size of the filter bags. This deformation affects the filtration efficiency and air permeability of the filter bags, greatly reducing their filtration effect. Therefore, we provide a multi-layer composite dust collector filter bag. Utility Model Content

[0004] The purpose of this invention is to provide a multi-layer composite dust collector filter bag to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer composite dust collector filter bag, comprising a filter bag body and a cage frame. The surface of the filter bag body is woven with a high-temperature resistant layer, which includes a PPS fiber layer, a PI fiber layer, and a PTFE fiber layer. The surface of the cage frame is provided with through holes, and the inner cavity of the cage frame is provided with connecting columns. The connecting columns and the cage frame are fixedly connected by a set of reinforcing ribs.

[0006] By adopting the above solution and utilizing the characteristics of PPS fiber layer, PI fiber layer and PTFE fiber layer, the filter bag body has the function of high temperature resistance, which can resist the erosion of high temperature exhaust gas and corrosive substances, reduce the damage caused by high temperature and chemical corrosion, thereby extending the service life of the filter bag body and reducing the replacement frequency and maintenance costs.

[0007] In a preferred embodiment of a multi-layer composite dust collector filter bag, the PPS fiber layer, PI fiber layer, and PTFE fiber layer have the same thickness, and each thickness is 0.3mm-0.9mm.

[0008] In a preferred embodiment of a multi-layer composite dust collector filter bag, the inner surface of the PPS fiber layer is woven onto the outer surface of the PI fiber layer, and the inner surface of the PI fiber layer is woven onto the outer surface of the PTFE fiber layer.

[0009] In a preferred embodiment of a multi-layer composite dust collector filter bag, the number of reinforcing ribs is four, and they are evenly wrapped around the surface of the connecting column.

[0010] By adopting the above solution and setting up connecting columns, the load-bearing capacity and deformation resistance of the cage are improved, which greatly extends the service life of the cage.

[0011] In a preferred embodiment of a multi-layer composite dust collector filter bag, the size of the cage is smaller than the size of the filter bag body, and the size of the cage is adapted to the internal cavity of the filter bag body.

[0012] By adopting the above solution, since the size of the cage frame is smaller than the size of the filter bag body, the filter bag body can be quickly fitted onto the surface of the cage frame, thereby improving the fitting efficiency.

[0013] In a preferred embodiment of a multi-layer composite dust collector filter bag, the through holes are evenly distributed on the surface of the cage frame, and the through holes are hexagonal in shape.

[0014] By adopting the above solution, the impurities in the exhaust gas can be introduced into the interior of the filter bag body through the through holes, preventing impurities from accumulating in the inner cavity of the cage and thus causing blockage of the through holes.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model utilizes the characteristics of PPS fiber layer, PI fiber layer and PTFE fiber layer to enable the filter bag body to have high temperature resistance, resist the erosion of high temperature exhaust gas and corrosive substances, reduce damage caused by high temperature and chemical corrosion, thereby extending the service life of the filter bag body and reducing the replacement frequency and maintenance cost.

[0017] 2. This utility model can stably support the filter bag body through the cage frame, ensuring that the filter bag body maintains the correct position and shape during the dust removal process. This helps the filter bag body not to deform or shift when subjected to airflow impact, thereby ensuring the dust removal effect. Attached Figure Description

[0023] Please see Figure 1-4 A multi-layer composite dust collector filter bag includes a filter bag body 1 and a cage frame 2. The surface of the filter bag body 1 is woven with a high-temperature resistant layer 6, which includes a PPS fiber layer 61, a PI fiber layer 62, and a PTFE fiber layer 63. The PPS fiber layer 61, PI fiber layer 62, and PTFE fiber layer 63 have the same thickness, which is 0.3mm-0.9mm. The inner surface of the PPS fiber layer 61 is woven onto the outer surface of the PI fiber layer 62, and the inner surface of the PI fiber layer 62 is woven onto the outer surface of the PTFE fiber layer 63. The surface of the cage frame 2 has through holes 3, and the inner cavity of the cage frame 2 has connecting posts 4. The connecting posts 4 and the cage frame 2 are fixedly connected by a set of reinforcing ribs 5. By utilizing the characteristics of the PPS fiber layer 61, PI fiber layer 62, and PTFE fiber layer 63, the filter bag body 1 has a high-temperature resistant function, which can resist the erosion of high-temperature exhaust gas and corrosive substances, reduce damage caused by high temperature and chemical corrosion, thereby extending the service life of the filter bag body 1 and reducing the replacement frequency and maintenance costs.

[0024] See Figure 2 As shown, there are four reinforcing ribs 5, which are evenly arranged around the surface of the connecting column 4. The installation of the connecting column 4 enhances the load-bearing capacity and deformation resistance of the cage frame 2, significantly improving its service life. Figure 1 As shown, the size of the cage frame 2 is smaller than the size of the filter bag body 1, and the size of the cage frame 2 is compatible with the inner cavity of the filter bag body 1. Because the size of the cage frame 2 is smaller than the size of the filter bag body 1, the filter bag body 1 can be quickly fitted onto the surface of the cage frame 2, thereby improving the fitting efficiency. Figure 1 As shown, the through holes 3 are evenly distributed on the surface of the cage frame 2. The through holes 3 are hexagonal in shape. By setting the through holes 3, impurities in the exhaust gas can be introduced into the interior of the filter bag body 1 through the through holes 3, preventing impurities from accumulating in the inner cavity of the cage frame 2, which would lead to blockage of the through holes 3.

[0025] In use, the filter bag body 1 is first placed on the surface of the cage frame 2. The cage frame 2 can stably support the filter bag body 1, ensuring that the filter bag body 1 maintains the correct position and shape during dust removal. This helps prevent the filter bag body 1 from deforming or shifting when impacted by airflow, thus ensuring the dust removal effect. At the same time, because the cage frame 2 is provided with through holes 3 and connecting columns 4, the cooperation between the connecting columns 4 and through holes 3 further enhances the load-bearing capacity and deformation resistance of the cage frame 2, increasing its service life. Furthermore, because the surface of the filter bag body 1 is woven with a high-temperature resistant layer 6, the characteristics of the high-temperature resistant layer 6 enable the filter bag body 1 to resist the erosion of high-temperature exhaust gas and corrosive substances, reducing damage caused by high temperature and chemical corrosion, thereby extending the service life of the filter bag body 1 and reducing the replacement frequency and maintenance costs.
