Description

Technical Field

[0001] This utility model relates to the field of dust collector filter bag technology, specifically a dust collector filter bag with a flow guiding mechanism. Background Technology

[0002] Dust collector filter bags are a type of high-efficiency dust collection filter material. They have good air permeability, high dust collection efficiency, and certain resistance to acids, alkalis, and heat. In order to achieve higher air passage efficiency, a flow guiding mechanism is required.

[0003] According to the description in the patent application (CN211098019U) of a dust collector filter bag with a flow guiding device, "This utility model relates to the field of dust collector filter bag technology, specifically a dust collector filter bag with a flow guiding device, including a bag cage, which is a cylindrical structure with a solid base plate at its bottom. A filter bag is fitted onto the outside of the solid base plate, and the side of the solid base plate is fixedly connected to the bottom of the bag cage. A positioning screw is provided through the solid base plate, and a flow dividing plate is provided below the bottom of the solid base plate." It has a bowl-shaped structure, with its top diameter larger than that of the solid base. A positioning cavity is welded to its inner bottom, and diverting plates are evenly distributed on its outer side. The positioning cavity is a cylindrical tube. The advantages are: This invention uses a positioning screw to thread a diverting plate to the bottom of the bag cage. The diverting plate has a bowl-shaped structure, and diverting plates are welded to its outer edge. Compared to traditional technology, this invention, through the diverting plate, can reduce the backflow phenomenon caused by air impacting the bottom of the bag cage, reduce energy loss, and improve the purification efficiency of exhaust gas.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During use, this utility model has a problem: the device guides air into the bag cage through an arc-shaped guide plate, which can prevent air backflow. However, when the air enters the bag cage and comes into contact with the solid base, it flows back up along the inner wall of the bag cage and then flows out in large quantities from the opening between the arc-shaped guide plate and the bag cage. This does not effectively prevent air backflow, resulting in low efficiency of air passing through the filter bag. Therefore, it is necessary to improve the dust collector filter bag with a guide mechanism to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a dust collector filter bag with a flow guiding mechanism to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a dust collector filter bag with a flow guiding mechanism, comprising a filter bag, wherein the top of the filter bag is provided with a flow guiding mechanism, a bag cage is provided inside the filter bag, and a protective mechanism is provided inside the bag cage.

[0008] The flow guiding mechanism includes an installation component and a flow guiding component. The installation component is disposed on the top of the filter bag, and the flow guiding component is disposed inside the installation component.

[0009] Preferably, the installation assembly includes a connecting ring, which is fixedly connected to the top of the filter bag and the bag cage. An installation block is fixedly connected to the outside of the connecting ring. A first bolt is threaded inside the connecting ring, and an anti-slip pad is movably connected to the outside of the first bolt. The filter bag and the bag cage can be installed in the use position through the installation block, which facilitates the installation of the filter bag and the bag cage and ensures stable use to prevent loosening.

[0010] Preferably, five first bolts are provided, and the five first bolts are symmetrically threaded inside the connecting ring. Four mounting blocks are provided, and the four mounting blocks are symmetrically fixedly connected to the outside of the connecting ring. By using the four mounting blocks for balanced fixation, the connecting ring can be firmly installed and will not loosen during use.

[0011] Preferably, the airflow guiding assembly includes a mounting ring, which is movably connected to the outside of the first bolt. The bottom of the mounting ring is fixedly connected to a blocking port, and the top of the mounting ring is fixedly connected to a conical air inlet. Air enters the filter bag and the cage through the conical air inlet. The blocking port can block backflow air, and the conical filter bag and cage can allow air to pass through quickly.

[0012] Preferably, the mounting ring has a through hole at the corresponding position of the first bolt, and the first bolt is movably connected inside the through hole. The anti-slip pad is in contact with the mounting ring, which facilitates the installation of the mounting ring and prevents the first bolt from loosening due to vibration during use.

[0013] Preferably, the protective mechanism includes a base plate, which is fixedly connected to the inside of the bag cage. A second bolt is fixedly connected to the inside of the base plate, and a nut is threaded onto the outside of the second bolt.

A second connecting plate is movably connected to the inside of the second bolt, and a second protective plate is fixedly connected to the outside of the second connecting plate. By supporting the filter bag and the bag cage with the first and second protective plates, the filter bag and the bag cage can be prevented from collapsing due to internal airflow turbulence, thus ensuring that the filter bag and the bag cage remain flat.

[0014] Preferably, the second bolt has a groove at the corresponding position of the first connecting plate and the second connecting plate, and the first connecting plate and the second connecting plate are movably connected inside the groove. The first protective plate and the second protective plate are in contact with the filter bag respectively. The groove limits the first connecting plate and the second connecting plate, which can prevent the first connecting plate and the second connecting plate from rotating inside the second bolt.

[0015] Compared with the prior art, the present invention provides a dust collector filter bag with a flow guiding mechanism, which has the following beneficial effects:

[0016] 1. The dust collector filter bag with a flow guiding mechanism, during use, guides the air through the set conical air inlet to concentrate the air into the middle position and enter the interior of the filter bag and bag cage. The conical filter bag and bag cage filter and discharge the air, and then guide the air back to the bottom through the blocking port, thereby effectively preventing air backflow, allowing the air to pass through quickly and improving the efficiency of air passage.

[0017] 2. During use, the dust collector filter bag with the flow guiding mechanism prevents the first connecting plate and the second connecting plate from rotating through the sliding groove by the second bolt. Then, the first protective plate and the second protective plate support the filter bag and the bag cage to prevent the filter bag and the bag cage from being deformed by the airflow and to ensure that the filter bag and the bag cage are flat and stable.

[0025] Please see Figure 1-5This utility model provides a technical solution: a dust collector filter bag with a flow guiding mechanism, including a filter bag 1, a flow guiding mechanism 2 provided on the top of the filter bag 1, a bag cage 4 provided inside the filter bag 1, and a protective mechanism 3 provided inside the bag cage 4.

[0026] In this embodiment, the flow guiding mechanism 2 includes an installation component 21 and a flow guiding component 22. The installation component 21 is disposed on the top of the filter bag 1, and the flow guiding component 22 is disposed inside the installation component 21. The installation component 21 includes a connecting ring 211, which is fixedly connected to the top of the filter bag 1 and the bag cage 4. An installation block 212 is fixedly connected to the outside of the connecting ring 211. A first bolt 213 is threadedly connected to the inside of the connecting ring 211, and an anti-slip pad 214 is movably connected to the outside of the first bolt 213. The filter bag 1 and the bag cage 4 can be installed in the use position through the installation block 212, which facilitates the installation of the filter bag 1 and the bag cage 4, and ensures stable use and prevents loosening. Five first bolts 213 are provided, and the five first bolts 213 are symmetrically threadedly connected to the inside of the connecting ring 211. Four installation blocks 212 are provided, and the four installation blocks 212 are symmetrically fixedly connected to the connecting ring 211. The ring 211 is securely installed by four mounting blocks 212, which balance and fix the ring 211. If it becomes loose during use, the flow guiding assembly 22 includes a mounting ring 221, which is movably connected to the outside of the first bolt 213. The bottom of the mounting ring 221 is fixedly connected to a blocking port 222, and the top of the mounting ring 221 is fixedly connected to a conical air inlet 223. Air enters the filter bag 1 and the bag cage 4 through the conical air inlet 223. The blocking port 222 can block the backflow of air. With the help of the conical filter bag 1 and the bag cage 4, air can pass through quickly. The mounting ring 221 has a through hole at the corresponding position of the first bolt 213, and the first bolt 213 is movably connected inside the through hole. The anti-slip pad 214 contacts the mounting ring 221 to facilitate the installation of the mounting ring 221 and prevent the first bolt 213 from loosening due to vibration during use.

[0027] In this embodiment, the protective mechanism 3 includes a base plate 31, which is fixedly connected to the inside of the bag cage 4. A second bolt 32 is fixedly connected inside the base plate 31, and a nut 33 is threaded onto the outside of the second bolt 32. A first connecting plate 34 is movably connected inside the second bolt 32, and a first protective plate 35 is fixedly connected to the outside of the first connecting plate 34. A second connecting plate 36 is movably connected inside the second bolt 32, and a second protective plate 37 is fixedly connected to the outside of the second connecting plate 36. The first protective plate 35 and the second protective plate 37 support the bag cage 4. The filter bag 1 and the bag cage 4 can prevent the filter bag 1 and the bag cage 4 from collapsing due to internal airflow turbulence, ensuring that the filter bag 1 and the bag cage 4 are flat. The second bolt 32 has a sliding groove at the corresponding position of the first connecting plate 34 and the second connecting plate 36, and the first connecting plate 34 and the second connecting plate 36 are movably connected inside the sliding groove. The first protective plate 35 and the second protective plate 37 are in contact with the filter bag 1 respectively. The sliding groove limits the first connecting plate 34 and the second connecting plate 36, which can prevent the first connecting plate 34 and the second connecting plate 36 from rotating inside the second bolt 32.

[0028] In actual operation, when this device is in use, the first connecting plate 34 and the second connecting plate 36 are aligned sequentially with the groove of the second bolt 32 and placed inside the second bolt 32. Then, the nut 33 is screwed on, which fixes the first connecting plate 34 inside the second bolt 32, so that the first protective plate 35 and the second protective plate 37 contact the filter bag 1. The connecting ring 211 can be installed in the use position through the mounting block 212, thereby fixing the position of the filter bag 1 and the bag cage 4. The mounting ring 221 is placed on top of the connecting ring 211, and then the first bolt 213 passes through the mounting ring 221 and is screwed on. The air enters the interior of the connecting ring 211, and then the first bolt 213 presses the anti-slip pad 214 to contact the mounting ring 221, thereby connecting the mounting ring 221 with the connecting ring 211. The anti-slip pad 214 can prevent the first bolt 213 from loosening. Then, the air enters the interior of the filter bag 1 and the bag cage 4 through the conical air inlet 223 and the blocking port 222. When the air impacts the bottom plate 31, the air rises along the inner wall of the bag cage 4. During the rising process, it can be filtered and discharged through the bag cage 4 and the filter bag 1. A small amount of air reaches the position of the blocking port 222, but is blocked by the blocking port 222, and returns to the position of the bottom plate 31 again with the newly entered air.
