Description

Technical Field

[0001] This invention relates to the field of baghouse dust collector technology, specifically to a dust removal module of a baghouse dust collector and its usage method. Background Technology

[0002] A baghouse dust collector (also known as a bag filter) is a high-efficiency dry dust collection device that uses fiber filter bags to capture dust particles in gas. Its working principle is as follows: when dust-laden gas passes through the filter bags, the dust is trapped on the surface of the filter bags, while clean gas passes through and is discharged. As the dust layer thickens, the system periodically removes the accumulated dust from the filter bags through a cleaning mechanism to maintain stable operation.

[0003] The main structure of a baghouse dust collector includes a filter bag system, a housing structure, a dust removal module, and an inlet / outlet air system. The dust removal module is divided into pulse cleaning and reverse air cleaning depending on the actual application scenario. Pulse cleaning is suitable for applications with large dust levels and filter bag lengths less than 8 meters. However, pulse cleaning is ineffective for filter bags longer than 8 meters, and the instantaneous airflow expansion during pulse cleaning can damage the filter bags. This application aims to improve the existing reverse air system. The reverse air system in the existing dust removal module mainly consists of a high-pressure pump and pipelines. The high-pressure pump provides high-speed airflow that enters from the inside of the filter bag, blowing off the dust adhering to the outside of the bag, causing the dust to fall to the bottom of the housing and be collected and removed. This is the technical principle of the existing technology. However, in actual operation, some damp dust condenses in the gaps of the filter bag, and simple reverse air cleaning cannot effectively remove it. To address this technical problem, those skilled in the art have proposed a dust removal module for a baghouse dust collector and its usage method. Summary of the Invention

[0004] The purpose of this invention is to improve the dust removal reverse blowing module of a bag filter dust collector, enabling it to clean dust condensed in the gaps of the filter bag. This invention provides a dust removal module for a bag filter dust collector and its usage method.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution: A dust removal module for a baghouse dust collector and its usage method include a box threaded connection, a high-pressure air pump threaded connection, a dust collector bag threaded connection, an air supply system threaded connection, and a control system for the baghouse dust collector. The high-pressure air pump threaded connection is electrically connected to the control system of the baghouse dust collector and controls the air speed thereon. The high-pressure air pump threaded connection is installed on the side wall of the box threaded connection and its outlet threaded connection is connected to the air supply system threaded connection. The end of the air supply system threaded connection is connected to a conversion pipeline threaded connection. An air knife threaded connection that extends into the bag cage and performs circumferential air blowing on the bag is rotatably connected to the conversion pipeline threaded connection. The device also includes a sealing device threaded connection that seals the inner opening of the dust collector bag threaded connection.

[0006] Furthermore, the conversion pipeline threaded connection is horizontally arranged and spans the top of multiple dust collector bag threaded connections. The conversion pipeline threaded connection is connected and fixed to the connecting pipeline threaded connection in the axial direction of the dust collector bag threaded connection. The air knife threaded connection includes an air duct threaded connection that is concentrically and rotatably installed with the connecting pipeline threaded connection. An air outlet threaded connection for air outlet is opened on the side wall of the air duct threaded connection. The air outlet threaded connection is long and strip-shaped with a trapezoidal cross-section.

[0007] Furthermore, it also includes a power component threaded connection that drives the duct threaded connection to rotate in an annular shape. The power component threaded connection includes a gear threaded connection fixed to the upper end of the duct threaded connection and a chain threaded connection that connects and meshes with the gear threaded connections on adjacent duct threaded connections. It also includes a servo motor threaded connection fixed to the side wall of the hopper threaded connection and electrically connected to the bag filter dust collector. The output shaft of the servo motor threaded connection is fixed to the gear threaded connection and the gear threaded connection on the duct threaded connection at the end is connected to it via a chain threaded connection. The servo motor threaded connection is also covered by a sealing threaded connection fixed to the outer wall of the hopper threaded connection.

[0008] Furthermore, the threaded connection of the sealing device includes a threaded connection constructed on the outer wall of the duct threaded connection and a sealing plate threaded connection that is threaded to the duct threaded connection. The inner opening of the bag cage is flared. The sealing plate threaded connection is used to seal the lower end of the inner opening of the bag cage and the upper surface of the sealing plate threaded connection is covered with a rubber pad threaded connection. It also includes a guide component threaded connection that guides the sealing plate threaded connection to move up and down.

[0009] Furthermore, the threaded connection of the guide assembly includes a pair of threaded connections of guide rods fixed to the inner opening of the bag cage. The threaded connections of the guide rods slide through the threaded connection of the sealing plate. The other ends of the two threaded connections of the guide rods are fixed to the same threaded connection of the ring sleeve, which is sleeved on the outside of the threaded connection of the air duct.

[0010] Furthermore, the threaded connection on the duct threaded connection is a partial structure, and its range is located at the lower edge when the ring threaded connection to the sealing plate threaded connection is used for sealing.

[0011] Furthermore, it also includes a wireless limit switch threaded connection electrically connected to the control system of the bag filter, wherein the operating head of the wireless limit switch threaded connection is fixed to the lower bottom of the sealing plate threaded connection, and the switch core of the wireless limit switch threaded connection is correspondingly fixed to the upper part of the ring threaded connection.

[0012] Furthermore, the threaded connection of the air supply system includes a main pipeline threaded connection that connects to the threaded connection end of the high-pressure air pump and multiple branch pipeline threaded connections. A solenoid valve threaded connection is installed between the branch pipeline threaded connection and the main pipeline threaded connection, and the other end of the solenoid valve threaded connection is connected to the conversion pipeline threaded connection. The solenoid valve threaded connection is electrically connected to the control system of the bag filter dust collector.

[0013] Furthermore, one end of the conversion pipeline threaded connection is connected to the branch pipeline threaded connection through a quick-press flange threaded connection, and the other end is welded and fixed with a fixing plate threaded connection. The fixing plate threaded connection bolts are fastened to the box bar of the box threaded connection.

[0014] A method for using the dust removal module of a bag filter dust collector includes the following steps: S1. The control system of the bag filter starts the high-pressure air pump threaded connection, solenoid valve threaded connection and servo motor threaded connection. At this time, the servo motor threaded connection rotates in the forward direction and drives the air duct threaded connection to rotate through the gear threaded connection and chain threaded connection. The sealing plate threaded connection moves upward under the guidance of the guide rod threaded connection until it disengages from the threaded connection and seals the bottom of the inner opening of the bag cage. S2. High-speed airflow is ejected from the threaded connection of the air duct, forming a sweeping airflow on the inner wall of the bag, causing the dust adhering to the outer wall of the bag to fall off. The movement time of the sealing plate threaded connection at the inner opening of the bag cage is a fixed value. During this time period, the airflow ejected from the threaded connection of the air duct will cause the swept area of ​​the inner wall of the bag to bulge outward and then return to its original position, which has a kneading effect. After this time, the sealing plate threaded connection seals the opening of the bag cage. At this time, the air pressure inside the bag increases, and the bag will bulge. The bulging bag can tear apart or blow away the dust clumps condensed on the outside of the bag. This process lasts for a fixed time. S3. After the bag filter has been inflated for a period of time, the control system of the bag filter decelerates and rotates in the opposite direction. At this time, the sealing plate opens the opening of the bag cage, the internal air pressure decreases, the bag recovers, and the air outlet of the duct continues to blow out airflow, blowing away any remaining dust clumps. S4. As the sealing plate threaded connection returns downward to the ring threaded connection, the wireless limit switch threaded connection is triggered. The control system of the bag filter dust collector, upon receiving the signal, controls the servo motor threaded connection, solenoid valve threaded connection, and high-pressure air pump threaded connection to close, completing a dust removal process.

[0015] The beneficial effects of this invention are as follows: This invention features a rotating connection between the duct and the connecting pipe, with an air outlet on the side for spraying air. This allows air to be sprayed onto the inside of the dust collector bag to clean the dust. When the duct rotates in a ring, the sprayed air causes the swept areas of the bag's inner wall to bulge outwards and then return to their original shape, creating a kneading and shaking effect.

[0016] This invention constructs threaded teeth on the upper part of the air duct. The sealing plate moves upward under the guidance of the guide rod until it disengages from the threaded teeth and seals the lower part of the inner opening of the bag cage. This increases the air pressure inside the dust collector bag, causing the bag to bulge. The bulging bag can tear apart or blow away the dust clumps that have condensed on the outside of the bag.

[0017] This invention connects one end of the conversion pipeline with a quick-press flange and the other end with a fixing plate and bolts, making disassembly convenient during duct maintenance. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] This embodiment provides a dust removal module for a bag filter dust collector, mainly used to improve the dust removal reverse air module of the bag filter dust collector, enabling it to clean dust condensed in the gaps of the filter bags. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-12 Please provide a detailed explanation: Example 1: A dust removal module for a baghouse dust collector includes a hopper 1, a high-pressure air pump 2, dust collector bags 3, an air supply system 4, and a control system for the baghouse dust collector. Please refer to [link / reference needed]. Figure 2 It should be explained here that the improved dust removal module of this application is installed on a bag filter dust collector. Therefore, all relevant structures of the existing bag filter dust collector should be included in the prior art, such as the control system of the bag filter dust collector mentioned here and the bag cage mentioned later. The details are as follows: the high-pressure air pump 2 is electrically connected to the control system of the bag filter dust collector and the air speed is controlled by it. In the prior art, the control system of the bag filter dust collector is a programmable control system. Therefore, the speed control of the high-pressure air pump 2 is the prior art that can be understood by those skilled in the art and will not be elaborated here. The high-pressure air pump 2 is installed on the side wall of the box 1 and the air outlet 602 is connected to the air supply system 4. The end of the air supply system 4 is connected to the conversion pipe 5. The conversion pipe 5 is rotatably connected to the air knife 6, which extends into the bag cage and blows air around the bag. The air knife 6 can spray the vertical airflow of the dust collector bag 3, and the circular movement of the overlapping air knife 6 can blow air to clean the inner part of the dust collector bag 3. It also includes a sealing device 7 to close the inner opening of the dust collector bag 3.

[0021] Please see Figure 4 and Figures 10 to 12The conversion pipe 5 is horizontally arranged and spans the top of multiple dust collector bags 3. The conversion pipe 5 is connected to and fixed with the connecting pipe 8 along the axial direction of the dust collector bags 3. Please refer to [link / reference]. Figure 10 The air knife 6 includes an air duct 601 that is rotatably mounted concentrically with the connecting pipe 8. The rotatable connection between the air duct 601 and the connecting pipe 8 can be seen from the upper part of the figure. The two are rotatably connected via bearings, and the gap is treated with a dynamic seal. Dynamic sealing technology is existing technology and will not be elaborated further here; please refer to [reference needed]. Figure 12 The bottom of the duct 601 has a bearing installed at the bottom of the filter bag cage. To create a vertical airflow that ejects air from the dust collector bags 3, an air outlet 602 is provided on the side wall of the duct 601. Figure 11 As can be seen, the air vent 602 is long and narrow with a trapezoidal cross-section. The trapezoidal shape is designed to accelerate the airflow. In this application, the air duct 601 is rotatably connected to the connecting pipe 8, and the air vent 602 is opened on the side to spray airflow. This allows airflow to be sprayed out to clean the inside of the dust collector bag 3. When the air duct 601 rotates in a ring, the sprayed airflow will cause the swept area of ​​the bag to bulge outward and then return to its original position, which has the effect of kneading and shaking.

[0022] Please see Figure 4 To achieve the axial rotation of the duct 601, a power assembly 9 is also included to drive the duct 601 to rotate in a ring. The power assembly 9 includes a gear 901 fixed to the upper end of the duct 601 and a chain 902 that connects and meshes with the gear 901 on adjacent ducts 601. When the chain 902 rotates, it can drive the adjacent ducts 601 to rotate synchronously. It also includes a servo motor 903 fixed to the side wall of the chamber 1 and electrically connected to the bag filter. The output shaft of the servo motor 903 is fixed to the gear 901, which is located on the end of the duct 601 and is connected to it by the chain 902. The rotation of the servo motor 903 drives the gear 901 to drive the chain 902 to drive the duct 601 to rotate. In order to ensure the airtightness of the chamber 1, the servo motor 903 is also covered with a cover 904 fixed to the outer wall of the chamber 1.

[0023] Example 2: This embodiment adds the following technical solution based on embodiment 1: the sealing device 7 includes a thread 701 formed on the outer wall of the air duct 601 and a sealing plate 702 connected to the thread 701 of the air duct 601. The inner opening of the bag cage is funnel-shaped. The sealing plate 702 is used to seal the lower end of the inner opening of the bag cage. When the sealing plate 702 closes the inner opening of the bag cage, the air pressure inside the bag increases and the bag bulges. At the same time, in order to ensure the sealing, the upper surface of the sealing plate 702 is covered with a rubber pad 10. It also includes a guide component 703 to guide the sealing plate 702 to move up and down.

[0024] Specifically, the guide assembly 703 includes a pair of guide rods 7031 fixed to the inner opening of the bag cage. The guide rods 7031 slide through the sealing plate 702. The other ends of the two guide rods 7031 are fixed to the same ring 7032. The ring 7032 is sleeved on the outside of the air duct 601. When the air duct 601 rotates, the sealing plate 702 connected to it by its thread 701 will move upward along the air duct 601 under the guidance of the guide rods 7031 until it closes the lower end of the inner opening of the bag cage.

[0025] In this embodiment, please refer to Figure 9 Considering that the sealing plate 702 cannot always move upwards, the thread 701 on the duct 601 is a partial structure, its range being from the ring 7032 to the lower edge of the sealing plate 702 when it is sealing. Figure 9 As can be seen, the sealing plate 702 is located at the ring 7032 at this time. When the air duct 601 rotates in the forward direction, the sealing plate 702 moves upward until it disengages from the thread 701. At this time, the rubber pad 10 on the upper surface of the sealing plate 702 can seal the lower end of the inner opening of the bag cage. Because the air duct 601 rotates in the forward direction, the sealing plate 702 cannot fall down. When the air duct 601 rotates in the reverse direction, the sealing plate 702, under the action of gravity, will re-engage with the thread 7032. 1. The threads engage and move downward under the action of the guide rod 7031 until they contact the ring 7032. In this embodiment, the upper part of the air duct 601 is constructed with threads 701. The sealing plate 702 moves upward under the guidance of the guide rod 7031 until it disengages from the threads 701 and seals the lower part of the inner opening of the bag cage. This increases the air pressure inside the dust collector bag 3, causing the bag to bulge. The bulging bag can tear apart or blow away the dust clumps condensed on the outside of the bag.

[0026] In this embodiment, to confirm when to stop working, a wireless limit switch 11 electrically connected to the control system of the bag filter is also included. The operating head of the wireless limit switch 11 is fixed to the bottom of the sealing plate 702, and the switch core of the wireless limit switch 11 is fixed above the ring 7032. When the control system of the bag filter operates to inflate the bag for a period of time, it controls the servo motor 903 to decelerate and rotate in the opposite direction. At this time, the sealing plate 702 opens the opening of the bag cage, the internal air pressure decreases, the bag recovers, and the airflow continues to blow out from the air outlet 602 of the air duct 601, blowing away any remaining dust clumps.

[0027] Example 3: To further enhance the feasibility of this solution, the air supply system 4 includes a main pipeline section 401 connected to the high-pressure air pump 2 and multiple branch pipeline sections 402. A solenoid valve 403 is installed between the branch pipeline section 402 and the main pipeline section 401, and the other end is connected to the conversion pipeline 5. The solenoid valve 403 is electrically connected to the control system of the bag filter. Adding the solenoid valve 403 allows the cleaning of the dust collector bag 3 to achieve the function of partial cleaning and partial operation according to the actual situation. One end of the conversion pipeline 5 is connected to the branch pipeline section 402 through a quick-press flange 12, and the other end is welded and fixed with a fixing plate 13. The fixing plate 13 is bolted to the box bar of the box 1. By connecting one end of the conversion pipeline 5 with a quick-press flange 12 and the other end with a fixing plate 13 and bolts, disassembly can be convenient when maintaining the air duct 601.

[0028] A method for using the dust removal module of a bag filter dust collector includes the following steps: S1. The control system of the bag filter starts the high-pressure air pump 2 (threaded 701 connection), the solenoid valve 403 (threaded 701 connection), and the servo motor 903 (threaded 701 connection). At this time, the servo motor 903 (threaded 701 connection) rotates in the forward direction, driving the air duct 601 (threaded 701 connection) to rotate through the gear 901 (threaded 701 connection) and the chain 902 (threaded 701 connection). The sealing plate 702 (threaded 701 connection) moves upward under the guidance of the guide rod 7031 (threaded 701 connection) until it comes out of the thread 701 (threaded 701 connection) and seals the bottom of the inner opening of the bag cage. S2. High-speed airflow is ejected from the air outlet 602 connected to the air duct 601 thread 701, forming a sweeping airflow on the inner wall of the filter bag, causing the dust adhering to the outer wall of the filter bag to fall off. The movement time of the sealing plate 702 thread 701 connected to the inner opening of the filter bag cage is a fixed value (this fixed value is actually determined by the speed of the servo motor 903, and the control system of the filter bag dust collector can control the actual speed of the servo motor 903, so the actual speed of the servo motor 903 can be modified according to the specific working conditions). During this time period, the airflow ejected from the air outlet 602 thread 701 will cause the swept area of ​​the filter bag to bulge outward and then recover, which has a kneading effect. After this time, the sealing plate 702 thread 701 connects to seal the opening of the filter bag cage. At this time, the air pressure inside the filter bag increases, and the filter bag will bulge. The bulging filter bag can tear or blow away the dust clumps condensed on the outside of the filter bag. This process lasts for a fixed time, and the parameters can be modified on the control system of the filter bag dust collector according to the actual situation. S3. After the bag filter dust collector operates for a period of time, the control system controls the servo motor 903 (threaded 701) to decelerate and rotate in the opposite direction. At this time, the sealing plate 702 (threaded 701) opens the opening of the bag cage, the internal air pressure decreases, the bag recovers, and the air outlet 602 (threaded 701) of the air duct 601 (threaded 701) continues to blow out airflow, blowing away any remaining dust clumps. S4. As the sealing plate 702 thread 701 connection moves downward back to the ring sleeve 7032 thread 701 connection, the wireless limit switch 11 thread 701 connection is triggered. The control system of the bag filter dust collector, upon receiving the signal, controls the servo motor 903 thread 701 connection, the solenoid valve 403 thread 701 connection, and the high-pressure air pump 2 thread 701 connection to close, completing a dust removal process.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
