Description

Technical Field

[0001] This utility model relates to the field of filters, and more particularly to a split-type bag filter. Background Technology

[0002] Bag filters are a type of multi-purpose filtration equipment with novel structure, small size, simple and flexible operation, energy saving, high efficiency, closed operation, and strong applicability. Bag filters are a type of pressure filtration device that typically uses one or more containers filled with filter bags to intercept particulate matter in a fluid, ensuring that the filtered fluid meets a certain purity standard.

[0003] Existing bag filters are typically used to remove solid particles and impurities from fluids to purify the medium. However, the filter bags and filter screens on current equipment are usually designed as a single unit and fixed with bolts. When replacement is needed, a large number of bolts need to be removed to take off the entire filter bag for replacement and then reinstalled. This not only consumes time and increases the difficulty of replacing the filter bag, but may also lead to unnecessary replacement of components such as the filter screen, resulting in high maintenance costs and great inconvenience in use.

[0004] Therefore, it is necessary to design a split-type bag filter that can install filter screen and adjustment frame while separately installing filter bag to filter gas multiple times, facilitate the replacement and removal of individual filter bags, save time, reduce maintenance costs, improve filtration effect, and is easy to use. Utility Model Content

[0005] To overcome the drawbacks of current equipment where filter bags are typically designed as a single unit, requiring the removal of numerous bolts to detach the entire filter bag for replacement and reinstallation—which is time-consuming, increases the difficulty of filter bag replacement, and may lead to unnecessary replacement of components such as the filter screen, resulting in high maintenance costs—this invention provides a separate bag filter that allows for the separate installation of filter bags while simultaneously installing the filter screen and adjustment frame for multiple filtrations of gas. This facilitates the replacement and removal of individual filter bags, saves time, reduces maintenance costs, improves filtration efficiency, and is easy to use.

[0006] Technical solution: A split-type bag filter includes an air inlet frame, an air outlet frame, a housing, a sealing door, an adjustment component, and a filter component. The housing is connected to the right side of the air inlet frame, and the air outlet frame is connected to the right side of the housing. The sealing door is rotatably connected to the upper right part of the air outlet frame. An adjustment component for adjusting the air intake is provided on the left side of the housing, and a filter component for filtering impurities in the gas is provided on the right side of the housing.

[0007] As a preferred technical solution of this utility model, the air intake frame is wider on the left and narrower on the right.

[0008] As a preferred technical solution of this utility model, the adjustment component includes a louvered fan, a sprocket, a chain, a motor, and a fixing frame. Multiple louvered fans are rotatably connected to the left side of the outer casing. Each louvered fan is connected to a sprocket at the front. A chain is wound around the sprockets. A fixing frame is connected to the upper left front side of the outer casing. A motor is connected to the fixing frame. The output shaft of the motor is connected to the uppermost sprocket.

[0009] As a preferred technical solution of this utility model, it also includes a fan, with the fan rotatably connected to the inner side of the left side of the housing.

[0010] As a preferred technical solution of this utility model, the filter assembly includes a filter screen, an adjusting frame, a slide rail, and filter bags. The filter screen is slidably engaged on the left side of the outer shell, and the louvers are all located on the left side of the filter screen. The adjusting frame is slidably engaged in the middle of the outer shell, and two slide rails are connected to the inner side of the middle of the outer shell. The slide rails are slidably engaged with the adjusting frame, and multiple filter bags are slidably engaged on the adjusting frame.

[0011] As a preferred technical solution of this utility model, it also includes handles, with handles connected to the upper sides of both the front and rear parts of the adjustment frame.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model allows the filter bag to be moved and installed on the adjustment frame, and the adjustment frame and filter screen to be moved and installed on the outer shell. Then, the individual filter bag can be moved and removed or the adjustment frame can be pulled to remove all the filter bags for replacement. This allows the filter bags to be installed separately while the filter screen and adjustment frame are installed to filter the gas multiple times. It is convenient to replace and remove individual filter bags, saves time, reduces maintenance costs, improves the filtration effect, and is easy to use.

[0013] 2. This utility model uses a fan to rotate, allowing gas to enter the outer casing. Larger particles in the gas are intercepted and filtered through a filter screen, allowing the gas to continue flowing. The gas then flows through a filter bag for secondary filtration, and the filtered gas is discharged from the exhaust frame. This allows for adjustment of the louvered fan angle to control the air intake, reducing impact and wear on the filter bag, extending the filter bag's service life, and improving filtration efficiency.

[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] A split-type bag filter, such as Figures 1-5 As shown, the device includes an air intake frame 1, an exhaust frame 2, a housing 3, a sealing door 4, a fan 10, a handle 15, an adjustment assembly, and a filter assembly. The air intake frame 1 is wider on the left and narrower on the right to facilitate air intake. The housing 3 is connected to the right side of the air intake frame 1, and the exhaust frame 2 is connected to the right side of the housing 3. The sealing door 4 is rotatably connected to the upper right part of the exhaust frame 2. The fan 10 is rotatably connected to the inner left side of the housing 3 to facilitate airflow. The left side of the housing 3 is provided with an adjustment assembly for adjusting the air intake volume. The adjustment assembly includes louvers 5, sprockets 6, chains 7, motors 8, and a fixing bracket 9. Ten louvers 5 are rotatably connected to the left side of the housing 3. Each louver 5 is connected to the front of a sprocket 6, and chains 7 are wound around the sprockets 6. The upper left front side of the housing 3 is connected to... The housing 3 is equipped with a fixed frame 9, on which a motor 8 is connected. The output shaft of the motor 8 is connected to the uppermost sprocket 6. The right side of the housing 3 is provided with a filter assembly for filtering impurities in the gas. The filter assembly includes a filter screen 11, an adjusting frame 12, a slide rail 13, and filter bags 14. The filter screen 11 is slidably engaged with the left side of the housing 3. The louvers 5 are all located to the left of the filter screen 11. The adjusting frame 12 is slidably engaged with the middle of the housing 3. Two slide rails 13 are connected to the inner side of the middle of the housing 3. The slide rails 13 are slidably engaged with the adjusting frame 12. Four filter bags 14 are slidably engaged with the adjusting frame 12. The upper sides of the front and rear parts of the adjusting frame 12 are connected with handles 15 for easy removal by pulling the adjusting frame 12.

[0022] When gas filtration is required, this device can be used. The sealing door 4 is opened by rotating it, then the filter bag 14 is brought into contact with the adjusting frame 12. The filter bag 14 is then moved to engage with the adjusting frame 12. Next, the adjusting frame 12 and the filter screen 11 are brought into contact with the outer casing 3. The adjusting frame 12 and the filter screen 11 are then moved to engage with the outer casing 3 and the slide rail 13, thus installing the filter bag 14, adjusting frame 12, and filter screen 11, achieving the separation and installation of the filter bag 14. The sealing door 4 is then closed by rotating it, allowing the air inlet frame 1 to connect to the gas delivery pipe. The air inlet frame 1 is wider on the left and narrower on the right. This facilitates air intake, allowing gas to enter the air intake frame 1. Then, the motor 8 on the mounting bracket 9 is activated, driving the corresponding sprocket 6 to rotate, causing the chain 7 to rotate, which in turn rotates the remaining sprockets 6, opening the louvers 5. After rotating to a suitable angle, the motor 8 is turned off, and then the fan 10 is activated. The fan 10's rotation allows gas to enter the outer casing 3 through the gaps between the louvers 5. Larger particles in the gas are intercepted and filtered by the filter screen 11, allowing the gas to continue flowing. It then flows through the filter bag 14 for secondary filtration, leaving other particles in the filter bag. In step 14, the filtered gas is discharged from the discharge frame 2, thereby allowing the angle of the louvered fan 5 to control the air intake, reducing impact and wear on the filter bag 14, extending the service life of the filter bag 14, and improving filtration efficiency. When the filter bag 14 needs to be replaced after a long period of use, the sealing door 4 can be rotated to open it, then the damaged filter bag 14 can be pulled to remove it, and then the new filter bag 14 can be brought into contact with the adjusting frame 12 and then pushed to move the filter bag 14 for installation. Alternatively, the adjusting frame 12 can be pulled off using the handle 15, and then all the filter bags 14 on the adjusting frame 12 can be removed for replacement. Then, the adjusting frame 12 is installed, and the sealing door 4 is turned to close. Then, the gas is filtered again. This allows the filter bag 14 to be installed separately while the filter screen 11 and the adjusting frame 12 are installed, so that the gas can be filtered multiple times. This facilitates the replacement and removal of individual filter bags 14, saves time, reduces maintenance costs, improves filtration effect, and is easy to use. After use, the fan 10 is turned off, and the motor 8 is reversed, causing the corresponding sprocket 6 to rotate in the opposite direction, causing the chain 7 to rotate in the opposite direction, causing the remaining sprockets 6 to rotate in the opposite direction, and causing the louvered fan 5 to rotate and reset. Then, the device can be cleaned.

[0023] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
