A pleated dust removal filter bag for aluminum industry

Abstract

This utility model discloses a pleated dust collector filter bag for the aluminum industry, including a bag frame, on which a filter bag is fitted. An installation frame is welded to the inner end face of the bag frame, and a servo motor is fixed on the installation frame. This utility model utilizes a designed servo motor, shaft, crank plate, crank column, swing frame, hammer rod, and guide frame. The servo motor drives the shaft to rotate, and the crank column at the end of the crank plate drives the swing frame to reciprocate, which in turn drives the hammer rod to move horizontally back and forth along the guide frame. This causes the end of the hammer rod to periodically strike the filter bag. The filter bag vibrates after being struck, effectively shaking off residual aluminum dust and impurities adhering to the outer surface, preventing aluminum dust accumulation and clogging of the filter bag pores. This ensures the filter bag maintains a stable filtration area and filtration efficiency. Simultaneously, the servo motor and other structural drives achieve automatic dust removal, eliminating the need for manual disassembly and cleaning, reducing manual maintenance workload and lowering maintenance costs.

Description

Technical Field

[0001] This utility model belongs to the technical field of pleated dust collector filter bags, specifically relating to a pleated dust collector filter bag for the aluminum industry. Background Technology

[0002] During the aluminum production process, a large amount of aluminum dust impurities are generated. These impurities need to be filtered and purified by installing dust collection filter bags into dust collection and filtration devices. When using existing pleated dust collection filter bags, aluminum dust has a certain adhesion and is easy to remain and adhere to the outer surface of the filter bag. As the usage time increases, the aluminum dust adhering to the outer surface of the filter bag will gradually accumulate and even cause blockage of the filter bag pores.

[0003] The existing pleated dust collector filter bags still have the following defects in use: (1) When the pleated dust collector filter bags are used for dust removal in the aluminum industry, the impurities adhering to the outer surface of the filter bag are difficult to be effectively removed by natural airflow alone. This leads to a gradual decrease in the filter area of ​​the filter bag and an increase in the filter resistance, which seriously affects the filtration efficiency and purification effect. At the same time, the filter bag after clogging needs to be frequently disassembled for cleaning or replacement, which increases the maintenance cost. Therefore, we propose a pleated dust collector filter bag for the aluminum industry. Utility Model Content

[0004] The purpose of this utility model is to provide a pleated dust collector filter bag for the aluminum industry, so as to solve the problem mentioned in the background art that the outer surface of the pleated dust collector filter bag is difficult to clean, which affects the filtration and purification effect and also increases the maintenance cost.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pleated dust collector filter bag for the aluminum industry, comprising a bag frame, a filter bag fitted on the outside of the bag frame, a mounting frame fixed to the inner end face of the bag frame by welding, a servo motor fixed on the mounting frame, a shaft fixed to the output end of the servo motor by welding, three crank plates fixed to the shaft by welding, a crank column fixed to one end surface of the crank plates by welding, a swing frame fitted on the outside of the crank column, a guide frame fixed to the mounting frame by welding, guide holes opened on both sides of the guide frame, and hammer rods penetrating through the guide holes on both sides, one end of the hammer rods being fixed to the outer wall of the swing frame by welding.

[0006] Preferably, hammer plates are provided on the outer sides of both sides of the guide frame, and the hammer plates are fixed to the hammer rod on the corresponding side by welding.

[0007] Preferably, a rubber strip is bonded to the surface of the hammer plate, and the cross-section of the rubber strip is semi-circular.

[0008] Preferably, the cross-section of the guide frame is U-shaped.

[0009] Preferably, the guide frame is fixed to the mounting frame at the connection between the two sides by welding with ribs, and the cross-section of the ribs is a triangular structure.

[0010] Preferably, the end surface of the guide frame is fixed with a support cylinder by welding, and the support cylinder is sleeved and installed on the outer wall of the shaft.

[0011] Preferably, the longitudinal section of the support cylinder is circular, the longitudinal section of the shaft is circular, and the central axes of the support cylinder and the shaft coincide.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) Through the designed servo motor, shaft, crank plate, crank column, swing frame, hammer rod and guide frame, the servo motor drives the shaft to rotate, the shaft drives the crank plate on its surface to rotate, the crank column at the end of the crank plate drives the swing frame to reciprocate, and then drives the hammer rod to move horizontally back and forth along the guide frame, so that the end of the hammer rod periodically hammers the filter bag. After being hammered, the filter bag vibrates, which can effectively shake off the aluminum dust impurities adhering to the outer surface, fundamentally avoiding the accumulation of aluminum dust and clogging the filter bag pores, ensuring that the filter bag always maintains a stable filtration area and filtration efficiency. At the same time, the automatic dust removal is achieved through the servo motor and other structural drives, without the need for manual disassembly and cleaning, reducing the amount of manual maintenance and lowering maintenance costs. The design incorporates a hammer plate connected to the end of the hammer rod on the same side to increase the contact area when the hammer rod strikes the filter bag, thereby improving the impact vibration effect. A semi-circular rubber strip is bonded to the surface of the hammer plate to buffer the impact force when striking the filter bag, preventing damage from rigid contact and extending the filter bag's service life. Triangular ribs reinforce the connection between the guide frame and the mounting frame, enhancing the structural strength of the guide frame and enabling it to withstand long-term reciprocating impact loads. A support cylinder, fitted around the outside of the shaft and coaxial with it, provides auxiliary support, reducing radial sway during shaft rotation and ensuring smooth swing operation of the device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a pleated dust collector filter bag for the aluminum industry, including a bag frame 1, a filter bag 2 fitted on the outside of the bag frame 1, a mounting frame 4 fixed to the inner end face of the bag frame 1 by welding, a servo motor 3 fixed to the mounting frame 4 by bolt assembly, a shaft 6 fixed to the output end of the servo motor 3 by welding, three crank plates 9 fixed to the shaft 6 by welding, a crank column 13 fixed to one end surface of the crank plate 9 by welding, a swing frame 5 fitted on the outside of the crank column 13, a guide frame 7 fixed to the mounting frame 4 by welding, guide holes 8 are opened on both sides of the guide frame 7, and hammer rods 10 pass through the guide holes 8 on both sides. Through the designed servo motor 3, shaft 6, crank plate 9, crank column 13, swing frame 5, and hammer rods 10, a complete dust collector filter bag is created. The rod 10 and the guide frame 7 are driven by the servo motor 3 to rotate the shaft 6. The shaft 6 drives the crank plate 9 on its surface to rotate. The crank column 13 at the end of the crank plate 9 drives the swing frame 5 to reciprocate, which in turn drives the hammer rod 10 to move horizontally back and forth along the guide frame 7. This causes the end of the hammer rod 10 to periodically hammer the filter bag 2. After being hammered, the filter bag 2 vibrates and shakes, which can effectively shake off the aluminum dust and impurities that remain on the outer surface. This fundamentally avoids the accumulation of aluminum dust that clogs the filter bag pores, ensuring that the filter bag 2 always maintains a stable filtration area and filtration efficiency. At the same time, automatic dust removal is achieved through the servo motor 3 and other structural drives, eliminating the need for manual disassembly and cleaning, reducing the workload of manual maintenance and lowering maintenance costs. One end of the hammer rod 10 is fixed to the outer wall of the swing frame 5 by welding.

[0023] In this embodiment, preferably, hammer plates 11 are provided on the outer sides of both sides of the guide frame 7. The hammer plates 11 are designed to be connected to the ends of the hammer rods 10 on the same side, so as to increase the hammering contact area and improve the hammering vibration effect when the hammer rods 10 hammer the filter bag 2. The hammer plates 11 are fixed to the hammer rods 10 on the corresponding side by welding.

[0024] In this embodiment, preferably, a rubber strip 12 is bonded to the surface of the hammer plate 11, and the cross-section of the rubber strip 12 is a semi-circular structure. With the design of the rubber strip 12, the semi-circular rubber strip 12 is bonded to the surface of the hammer plate 11. When the filter bag 2 is hammered, the rubber strip 12 can buffer the impact force, avoid damage to the filter bag 2 by rigid contact, and extend the service life of the filter bag 2. The cross-section of the guide frame 7 is a U-shaped structure.

[0025] In this embodiment, preferably, the connection between the guide frame 7 and the mounting frame 4 on both sides is fixed by welding with ribs 14. Through the designed ribs 14, the connection between the guide frame 7 and the mounting frame 4 is reinforced by triangular ribs 14, which improves the structural strength of the guide frame 7 and can withstand long-term reciprocating impact loads. The cross-section of the ribs 14 is a triangular structure.

[0026] In this embodiment, preferably, the end surface of the guide frame 7 is fixed with a support cylinder 15 by welding. The support cylinder 15 is sleeved on the outer wall of the shaft 6. The longitudinal section of the support cylinder 15 is circular, and the longitudinal section of the shaft 6 is also circular. Through the designed support cylinder 15, the support cylinder 15 is sleeved on the outside of the shaft 6 and is coaxially arranged with the shaft 6, which plays an auxiliary support role for the shaft 6, reduces the radial sway when the shaft 6 rotates, and ensures that the swing operation of this utility model is stable. The central axes of the support cylinder 15 and the shaft 6 coincide with each other.

[0027] The working principle and usage process of this utility model: The pleated dust collector filter bag is used in bag dust collectors for dust removal in the aluminum industry. Its working principle is that dust particles are intercepted when they collide with the filter cloth fibers due to inertial force. When the bag dust collector is running, the dust is attached to the outer surface of the dust collector filter bag. When the dust-laden gas passes through the dust collector, the dust is captured on the outer surface of the dust collector filter bag, while the clean gas enters the inside of the filter bag through the filter material. The skeleton inside the dust collector filter bag is used to support the filter bag and prevent the filter bag from collapsing.

[0028] This invention uses a mounting bracket 4 with a servo motor 3, which is welded to the inner end of a bag frame 1. The servo motor 3 is connected to the control power supply of the dust removal device. The servo motor 3 is model 57BLY70-230. Turning on the control power causes the output shaft of the servo motor 3 to rotate. After the servo motor 3 starts, its output end drives the shaft 6 to rotate around its own axis. The shaft 6 is fixed to the crank plate 9 by welding. Therefore, when the shaft 6 rotates, it synchronously drives the three crank plates 9 to rotate around the axis of the shaft 6. The crank column 13 at the end of the crank plate 9 is sleeved in the swing frame 5. When the crank plate 9 rotates with the shaft 6, the crank column 13 moves in a circular trajectory along the inner wall of the swing frame 5, thereby pushing the swing frame 5 along the horizontal direction. The swing frame 5 swings back and forth (i.e., moves towards and away from the filter bag 2). The outer wall of the swing frame 5 is welded and fixed to the hammer rod 10, and the hammer rod 10 passes through the guide holes 8 on both sides of the guide frame 7. Driven by the reciprocating swing of the swing frame 5, the hammer rod 10 moves horizontally back and forth along the axis of the guide hole 8. The hammer plate 11 at the end of the hammer rod 10 moves back and forth synchronously with the hammer rod 10. When the hammer rod 10 moves towards the filter bag 2, the rubber strip 12 on the surface of the hammer plate 11 contacts the outer wall of the filter bag 2 and applies an impact force. The filter bag 2 vibrates after being impacted. The vibration inertia separates the aluminum dust and impurities adhering to the outer surface from the filter bag, thus achieving dust removal. Then the hammer rod 10 moves in the opposite direction, and the hammer plate 11 detaches from the filter bag 2, waiting for the next hammering cycle.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
