Description

Technical Field

[0001] This utility model relates to the field of bag filter technology, and in particular to a filter bag removal device for a dust collector. Background Technology

[0002] Dust collectors are widely used in industrial production to remove dust particles from gases, ensuring a clean production environment and the normal operation of equipment. Filter bags, as the core filtration component, bear the primary responsibility for dust filtration. During long-term operation, filter bags are prone to clogging, damage, or saturation, requiring regular replacement to maintain dust removal efficiency and equipment safety.

[0003] Most existing methods for removing filter bags rely on manual operation. Especially in scenarios where the internal space of a bag filter is small and there are many filter bags, manually removing filter bags one by one is not only inefficient and labor-intensive, but also poses risks such as inconvenience, personnel fatigue, and damage to equipment or filter bags due to improper operation.

[0004] For example, patent application CN222804882U describes a dust collector filter bag support frame, including a base plate. A support rod is fixedly connected to the top surface of the base plate, and a fixing ring is fixedly connected to the top of the support rod. A limiting groove is formed on the top surface of the fixing ring. When a filter bag needs to be installed, the bag opening is folded into the limiting groove. The drive mechanism is pulled to drive the snap-fit ​​mechanism to slide and squeeze the elastic limiting component. The connecting ring and the pressure ring are pressed down along the inner wall of the limiting groove to squeeze the filter bag through the reserved gap for fixation. The drive mechanism is released, and the spring force of the elastic limiting component pushes the snap-fit ​​mechanism to reset, thus completing the snap-fit ​​fixing of the connecting ring and the pressure ring, as well as the fixed installation of the filter bag. Conversely, the filter bag can be quickly disassembled. This achieves the goal of facilitating the quick installation and disassembly of filter bags through the support frame, avoiding the problem that the existing filter bag disassembly and assembly process is too complicated, resulting in very cumbersome, time-consuming and labor-intensive cleaning and replacement of filter bags. While the above technical solutions can assist in the assembly and disassembly of filter bags, they are inconvenient for removing collected or wrapped filter bags during use, and also inconvenient for fixing and removing the outer ends of the filter bags. Furthermore, they cannot achieve the necessary rotation to remove the filter bags from the dust collector.

[0005] To address the aforementioned problems, this utility model provides a dust collector filter bag removal device that is structurally sound, easy to operate, and capable of achieving efficient and automated filter bag removal. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a dust collector filter bag removal device.

[0007] The purpose of this utility model is achieved as follows: A dust collector filter bag removal device includes a bracket, and a drive mechanism is provided on the upper part of the bracket. The drive mechanism can drive a turntable to rotate. The drive mechanism is existing technology and will not be described in detail. It is sufficient to drive the turntable to rotate, such as a motor. A turntable is provided at the output end of the drive mechanism. Multiple extension rods and at least one connecting rod are provided on the outer side of the turntable. A support rod mechanism is provided on the front side of the extension rod, and a pressure rod mechanism is provided on the connecting rod.

[0008] The strut mechanism includes two parallel struts.

[0009] The support rod is a round rod structure, which makes it easy to remove the wrapped filter bag from the support rod.

[0010] In use, the device is fixed on the ground, and the outer end of the filter bag is fixed to the support rod mechanism (two parallel support rods are provided to wrap and squeeze the outer end of the filter bag onto the two support rods, thereby fixing the filter bag); the controller controls the drive structure to rotate, which in turn drives the turntable to rotate. When the turntable rotates, it drives the extension rod and the connecting rod to rotate, thereby wrapping the filter bag around the support rod and the pressure rod, and then pulling the filter bag out of the dust collector and wrapping it onto the device.

[0011] After the filter bag is wound (i.e. pulled out of the dust collector), the controller stops the drive mechanism from rotating. Then, the pressure rod is rotated inward (i.e., the limit pin is pulled backward, at which point the limit pin disengages from the limit hole, the spring is compressed, and the limit rod and connecting rod are released. Then, the limit rod is rotated so that the front side of the limit rod does not adhere to or interfere with the rear side of the connecting rod, and the pressure rod is rotated so that the pressure rod rotates inward along the axis between the connecting plate and the connecting rod). This releases the internal limit on the wound filter bag, allowing the wound filter bag to contract inward and release the tension of the wound filter bag. Then, the wound filter bag is pulled outward, allowing the wound filter bag to detach from the support rod and the pressure rod, completing the removal of the filter bag from the dust collector and simultaneously completing the winding and unwinding of the filter bag.

[0012] Beneficial effects: This utility model has the following technical effects when used:

[0013] 1. Improve filter bag removal efficiency: The drive mechanism drives the turntable to rotate, which in turn drives the extension rod and connecting rod to rotate. In conjunction with the support rod mechanism and the pressure rod mechanism, the filter bag can be automatically wound and pulled out, avoiding repeated manual pulling, improving removal efficiency and reducing labor intensity.

[0014] 2. Pressure rod limiting design to prevent interference: The upper end of the connecting rod adopts a composite structure with an arc at the front and a flat at the back, which can form an effective limit after the pressure rod is unfolded, avoiding excessive rotation and interference, thus enhancing the coordination of the device structure and its service life.

[0015] 3. Convenient disassembly and winding in one: The combination design of the limiting pin and limiting rod structure allows the pressure rod to be quickly unlocked, rotated and retracted after winding, releasing the filter bag from its tight state, which facilitates subsequent extraction and collection, and improves the continuity and convenience of the overall operation process.

[0022] Example 1, as Figure 1-3 As shown, the purpose of this utility model is achieved as follows: A dust collector filter bag removal device includes a bracket 1. A drive mechanism 9 is provided on the upper part of the bracket 1. The drive mechanism 9 can drive the turntable 3 to rotate. The drive mechanism 9 is existing technology and will not be described in detail. It is sufficient to drive the turntable 3 to rotate, such as a motor. The output end of the drive mechanism 9 is provided with a turntable 3. Multiple extension rods 4 and at least one connecting rod 6 are provided on the outer side of the turntable 3. A support rod 5 mechanism is provided on the front side of the extension rods 4, and a pressure rod 7 mechanism is provided on the connecting rod 6.

[0023] The strut mechanism includes two parallel struts 5. The struts 5 are round rods, which facilitates the removal of the wound filter bag from the struts 5.

[0024] The pressure rod 7 mechanism includes a pressure rod 7, which can rotate towards the center of the turntable 3. A connecting plate 811 is fixedly installed on the rear side of the pressure rod 7, and the lower end of the connecting plate 811 is rotatably connected to the connecting rod 6. A connecting seat is rotatably installed on the outer side of the connecting plate 811, and a limit rod 10 is rotatably installed at the rear end of the connecting seat. The limit rod 10 is located on the rear side of the connecting rod 6. A limit hole is opened on the connecting rod 6, and a limit pin 14 is movably installed on the limit rod 10. The front end of the limit pin 14 is movably located in the limit hole. A limit ring 12 is fixedly installed on the outer side of the limit pin 14, and a spring 13 groove is opened in the limit rod 10. The limit ring 12 is movably located in the spring 13 groove, and a spring 13 is installed in the spring 13 groove. The spring 13 is located on the outer side of the limit pin 14; the front and rear ends of the spring 13 are connected to the limit ring 12 and the spring 13 groove, respectively.

[0025] The front of the upper end face of the connecting rod 6 is an arc-shaped structure, and the rear of the upper end face of the connecting rod 6 is a flat structure. The flat structure of the rear of the upper end face of the connecting rod 6 fits against the lower surface of the rear end of the pressure rod 7. Through the above structure, when the pressure rod 7 is horizontally unfolded, the rear end of the pressure rod 7 is limited by the flat structure of the rear of the upper end of the connecting rod 6, preventing it from continuing to rotate backward, thus limiting the rotation angle of the pressure rod 7. At the same time, the arc-shaped structure at the front of the upper end face of the connecting rod 6 can prevent rotational interference between the structures when the pressure rod 7 rotates.

[0026] The pressure rod 7 mechanism includes a pressure rod 7, which is movable up and down on the connecting rod 6. The rear end of the pressure rod 7 is connected to a lifting block 16. A lifting groove is provided on the connecting rod 6. The lifting block 16 is movable up and down in the lifting groove. A rotating rod 15 is rotatably provided on the upper end of the lifting block 16. The upper end of the rotating rod 15 is threaded through the upper end of the connecting rod 6.

[0027] When using this utility model, the device is fixed on the ground, and the outer end of the filter bag is fixed on the support rod 5 mechanism (two parallel support rods 5 are provided to wrap and squeeze the outer end of the filter bag onto the two support rods 5, thereby fixing the filter bag); the controller 2 controls the drive structure to rotate, which in turn drives the turntable 3 to rotate. When the turntable 3 rotates, it drives the extension rod 4 and the connecting rod 6 to rotate, thereby wrapping the filter bag around the support rod 5 and the pressure rod 7, and then pulling the filter bag out of the dust collector and wrapping it onto this device.

[0028] After the filter bag is wound (i.e. pulled out of the dust collector), the controller 2 controls the drive mechanism 9 to stop rotating. Then, the pressure rod 7 is rotated inward (i.e., the limit pin 14 is pulled backward, at which point the limit pin 14 disengages from the limit hole, the spring 13 is compressed, and the limit rod 10 and the connecting rod 6 are released from their respective limits. Then, the limit rod 10 is rotated so that the front side of the limit rod 10 does not fit or interfere with the rear side of the connecting rod 6. Then, the pressure rod 7 is rotated so that the pressure rod 7 rotates inward along the axis between the connecting plate 811 and the connecting rod 6). The internal limit on the wound filter bag is released, so that the wound filter bag can shrink inward, releasing the tension of the wound filter bag. Then, the wound filter bag is pulled outward, so that the wound filter bag is detached from the support rod 5 and the pressure rod 7, completing the removal of the filter bag from the dust collector and simultaneously completing the winding and unwinding of the filter bag.

[0029] Example 1, as Figure 4 As shown, after the filter bag is wound (i.e. pulled out of the dust collector), the controller 2 controls the drive mechanism 9 to stop rotating, and then moves the pressure rod 7 inward (i.e., rotates the rotating rod 15 to make the pressure rod 7 move downward along the lifting groove); the internal limit of the wound filter bag is released, so that the wound filter bag can shrink inward, release the tension of the wound filter bag, and then pull the wound filter bag outward, so that the wound filter bag is detached from the support rod 5 and the pressure rod 7, completing the removal of the filter bag from the dust collector, and at the same time completing the winding and closing of the filter bag.
