Description

Technical Field

[0001] This utility model relates to the field of aluminum ash screening technology, specifically to an aluminum ash screening device with a bag filter structure. Background Technology

[0002] The aluminum ash screening device with bag filter structure is a device that integrates aluminum ash screening and dust collection functions. It separates particles of different sizes through the screening action of the screening device. The dust generated during the screening process is captured by the dust collection pipe and introduced into the dust collection device through the air conveying pipe. In the dust collection box of the dust collection device, the dust particles are trapped by the filter bags of the bag filter, while the clean air is discharged through the filter bags.

[0003] While existing dust removal mechanisms offer numerous advantages during use, they still suffer from several problems. Firstly, their airflow is not smooth enough. Because the dust removal mechanism requires airflow pipes to transport dust-laden air from the screening device, dust particles tend to accumulate and clump at bends in the pipes, leading to blockages. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides an aluminum ash screening device with a bag filter structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is an aluminum ash screening device with a bag dust removal structure, including a screening device body, a bearing seat, an air supply pipe and a threaded sleeve. An air supply pipe is provided on one outer wall of the screening device body. A connecting pipe is provided through one end of the outer wall of the air supply pipe. A bearing seat is installed on one side of the inner wall of the air supply pipe. A screw is rotatably installed inside the bearing seat and the air supply pipe. A threaded sleeve with a threaded connection is provided on one side of the outer wall of the screw. Dust covers are adhered and fixed to the outer walls of both ends of the threaded sleeve. Connecting frames distributed in a circular array are welded to the outer walls of both sides of the threaded sleeve.

[0006] By adopting the above technical solution, the screening device body can perform screening operations on aluminum ash, and the dust-laden air inside the screening device body can be transported to the dust removal device body for dust removal operations through the air supply pipe and connecting pipe. The bearing seat ensures the stability of the screw's rotation position, and the threaded sleeve can move relative to the screw's rotation, allowing the threaded sleeve to move inside the air supply pipe. The dust cover can shield both sides of the threaded sleeve to prevent dust from contacting the screw, ensuring the tightness between the screw and the threaded sleeve, and ensuring the accuracy of adjusting the position of the threaded sleeve.

[0007] Specifically, a pipe joint is inserted and installed on the outer wall of one end of the gas transmission pipe, the connecting pipe is connected to the pipe joint, and the gas transmission pipe is connected to the inside of the connecting pipe through the pipe joint. The other end of the connecting pipe is flanged and connected to the dust removal device body.

[0008] By adopting the above technical solution, the pipe joint ensures the stability and reliability of the dust removal system. This connection method simplifies the installation process, reduces the risk of leakage, and after the dust-laden gas inside the screening device is transported to the dust removal device, the dust particles inside the gas can be filtered and removed.

[0009] Specifically, a fastener is welded to the outer wall of one side of the gas pipeline, and the fastener has screws arranged in a rectangular array inside, and the fastener is connected to the outer wall of the screening device body through the screws.

[0010] By adopting the above technical solution, the fixing component provides a stable support and fixation for the gas pipeline. This design not only enhances the stability of the gas pipeline, but also facilitates the adjustment of the position and angle of the gas pipeline according to actual needs, thereby improving the flexibility and practicality of the device.

[0011] Specifically, the outer wall of the gas transmission pipe is fitted with equally spaced parallel dust collection pipes, which are designed to be inclined relative to the connecting pipe.

[0012] By adopting the above technical solution, the dust collection pipe is designed with an inclined shape, which is conducive to the collection and emission of dust. This design can more effectively capture the dust generated during the screening process, reduce the accumulation and blockage of dust in the air conveying pipe, and improve the dust removal efficiency and the stability of the device.

[0013] Specifically, a drive motor is installed on the outer wall of one end of the screw that passes through the gas pipeline, and the drive motor is connected to the outer wall of the gas pipeline.

[0014] By adopting the above technical solution, the drive motor provides power for the rotation of the screw, thereby enabling the threaded sleeve to adjust its position as needed, ensuring precise adjustment of the threaded sleeve's position.

[0015] Specifically, limit rods are welded to both outer walls of the bearing housing, the connecting frame is movably installed on the outside of the limit rods, and equidistant parallel connecting rings are installed on both the upper and lower outer walls of the dust cover, the connecting rings being movably installed on the outside of the limit rods.

[0016] By adopting the above technical solution, the limiting rod provides stable support and guidance for the dust cover and connecting frame. This design not only enhances the stability and reliability of the dust cover, but also facilitates the adjustment of the position and angle of the dust cover as needed. After the dust cover moves according to the threaded sleeve, it can be folded to ensure the dust cover's sealing of the screw, prevent the dust cover from getting stuck in the screw threads, and ensure the stability of the threaded sleeve's movement.

[0017] Specifically, a retaining ring is welded to the outer wall of the connecting frame, and a scraper is adhered and fixed to the outer wall of the retaining ring, with the scraper in contact with the inner wall of the gas pipeline.

[0018] By adopting the above technical solution, the design of the baffle ring and scraper can more effectively clean the dust and residue on the inner wall of the air delivery pipe. This design not only improves dust removal efficiency but also extends the service life of the air delivery pipe. Furthermore, based on the movement of the threaded sleeve, the baffle ring can block the dust collection pipe, ensuring the suction pressure at different locations inside the screening device and ensuring uniform dust collection.

[0019] The beneficial effects of this utility model are:

[0020] (1) The aluminum ash screening device with bag dust removal structure described in this utility model has a dust cover that can shield both sides of the threaded sleeve to prevent dust from contacting the screw, ensuring the tightness between the screw and the threaded sleeve, and ensuring the accuracy of adjusting the position of the threaded sleeve.

[0021] (2) The aluminum ash screening device with bag dust removal structure described in this utility model can more effectively clean the dust and residue on the inner wall of the air conveying pipe. This design not only improves the dust removal efficiency, but also extends the service life of the air conveying pipe. In addition, according to the movement of the threaded sleeve, the baffle ring can block the dust collection pipe, which can ensure the dust suction pressure at different positions inside the screening device body and ensure the uniformity of dust suction.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the aluminum ash screening device with a bag filter structure of the present invention includes a screening device body 1, a bearing seat 2, an air supply pipe 11, and a threaded sleeve 22. An air supply pipe 11 is provided on one outer wall of the screening device body 1. A connecting pipe 12 is provided on one end of the outer wall of the air supply pipe 11. A bearing seat 2 is installed on one side of the inner wall of the air supply pipe 11. A screw 21 is rotatably installed inside the bearing seat 2 and the air supply pipe 11. A threaded sleeve 22 with a threaded connection is provided on one side of the outer wall of the screw 21. Dust covers 23 are glued and fixed to the outer walls of both ends of the threaded sleeve 22. A circular array of connecting frames 28 are welded to the outer walls of both sides of the threaded sleeve 22.

[0030] During use, the screening device body 1 can screen aluminum ash, and the dust-laden air inside the screening device body 1 can be transported to the dust removal device body 13 through the air supply pipe 11 and the connecting pipe 12 for dust removal. The bearing seat 2 ensures the stability of the rotation position of the screw 21, and the threaded sleeve 22 can move relative to the rotation of the screw 21, allowing the threaded sleeve 22 to move inside the air supply pipe 11. The dust cover 23 can shield both sides of the threaded sleeve 22 to prevent dust from contacting the screw 21, ensuring the tightness between the screw 21 and the threaded sleeve 22, and ensuring the accuracy of the adjustment of the threaded sleeve 22's position.

[0031] For gas delivery, exemplarily, such as Figure 2 As shown, a pipe joint 14 is inserted and installed on the outer wall of one end of the gas transmission pipe 11. The connecting pipe 12 is connected to the pipe joint 14, and the gas transmission pipe 11 is connected to the inside of the connecting pipe 12 through the pipe joint 14. The other end of the connecting pipe 12 is connected to the dust removal device body 13 by a flange.

[0032] During use, the pipe joint 14 ensures the stability and reliability of the dust removal system. This connection method simplifies the installation process, reduces the risk of leakage, and after the dust-laden gas inside the screening device body 1 is transported to the dust removal device body 13, it can filter and remove the dust particles inside the gas.

[0033] To fix the usage location, for example, such as Figure 2 As shown, a fastener 15 is welded to the outer wall of one side of the gas pipeline 11. The fastener 15 has screws arranged in a rectangular array inside, and the fastener 15 is connected to the outer wall of the screening device body 1 by the screws.

[0034] During use, the fixing component 15 provides a stable support and fixation for the gas pipe 11. This design not only enhances the stability of the gas pipe 11, but also facilitates the adjustment of the position and angle of the gas pipe 11 according to actual needs, thereby improving the flexibility and practicality of the device.

[0035] For dust collection, for example, such as Figure 2 As shown, the outer wall of the gas transmission pipe 11 is fitted with equally spaced parallel dust collection pipes 16, which are designed to be inclined relative to the connecting pipe 12.

[0036] When in use, the dust collection pipe 16 is designed with an inclined shape, which is conducive to the collection and discharge of dust. This design can more effectively capture the dust generated during the screening process, reduce the accumulation and blockage of dust in the air conveying pipe 11, and improve the dust removal efficiency and the stability of the device.

[0037] To drive rotation, for example, such as Figure 2 As shown, a drive motor 17 is installed on the outer wall of one end of the screw 21 that passes through the gas supply pipe 11, and the drive motor 17 is connected to the outer wall of the gas supply pipe 11.

[0038] During use, the drive motor 17 provides power for the rotation of the screw 21, thereby enabling the threaded sleeve 22 to adjust its position as needed, ensuring that the position of the threaded sleeve 22 is accurately adjusted.

[0039] For smooth mobile operation, for example, such as Figure 3 As shown, limit rods 25 are welded to both outer walls of the bearing housing 2, and connecting brackets 28 are movably installed on the outside of the limit rods 25. Connecting rings 24 are equidistantly and parallelly distributed on both the upper and lower outer walls of the dust cover 23, and the connecting rings 24 are movably installed on the outside of the limit rods 25.

[0040] During use, the limiting rod 25 provides stable support and guidance for the dust cover 23 and the connecting frame 28. This design not only enhances the stability and reliability of the dust cover 23, but also facilitates the adjustment of the position and angle of the dust cover 23 as needed. After the dust cover 23 moves according to the threaded sleeve 22, it can be folded to ensure the dust cover 23's sealing of the screw 21, prevent the dust cover 23 from getting stuck in the threads of the screw 21, and ensure the stability of the movement of the threaded sleeve 22.

[0041] For scraping and cleaning, for example, such as Figure 4 As shown, a retaining ring 26 is welded to the outer wall of the connecting frame 28, and a scraper 27 is adhered and fixed to the outer wall of the retaining ring 26. The scraper 27 is in contact with the inner wall of the gas transmission pipe 11.

[0042] During use, the design of the baffle ring 26 and scraper 27 can more effectively clean the dust and residue on the inner wall of the air supply pipe 11. This design not only improves dust removal efficiency but also extends the service life of the air supply pipe 11. Furthermore, based on the movement of the threaded sleeve 22, the baffle ring 26 can block the dust collection pipe 16, ensuring the suction pressure at different locations inside the screening device body 1 and ensuring uniform dust collection.

[0043] When using this invention, the screening device body 1 is activated to begin screening aluminum ash. During the screening process, the aluminum ash is separated into particles of different sizes, while dust-laden air is generated. The dust-laden air is transported to the dust removal device body 13 through the dust collection pipe 16, air conveying pipe 11, and connecting pipe 12 inside the screening device body 1. The dust removal device body 13 filters and removes the dust particles inside the gas to ensure that the emitted air meets environmental protection requirements.

[0044] When the equipment requires maintenance, it is stopped, and the drive motor 17 is started, causing the screw 21 to rotate under the support of the bearing housing 2. As the screw 21 rotates, the threaded sleeve 22 moves inside the air supply pipe 11, simultaneously moving the dust cover 23 along with it. The dust cover 23 moves with the threaded sleeve 22, always shielding the screw 21 and preventing dust from directly contacting it. This ensures the tightness between the screw 21 and the threaded sleeve 22, as well as the accuracy of adjusting the position of the threaded sleeve 22.

[0045] As the threaded sleeve 22 moves, the retaining ring 26 and scraper 27 clean the inner wall of the gas pipeline 11, removing the attached dust and residue.
