Description

Technical Field

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

[0002] Baghouse dust collection systems are widely used in metallurgy, chemical industry, power generation, and many other fields due to their high dust removal efficiency. This system primarily filters dust-laden gas through filter bags, trapping dust on the surface of the filter bags to purify the gas. However, over time, dust accumulates on the filter bag surface, increasing filter bag resistance, gradually reducing airflow, and consequently affecting dust removal efficiency and the normal operation of the system.

[0003] Currently, existing baghouse dust collection systems mostly rely on manual periodic inspection and replacement of filter bags to address the problem of reduced airflow due to excessive dust in the filter bags. This method not only requires a significant investment of manpower, but also, due to the time intervals between manual inspections, it is difficult to detect filter bag blockage in a timely manner, easily leading to a decrease in dust collection efficiency and even affecting the continuity of the entire production process. In view of this, this utility model proposes a baghouse monitoring and compensation dust collection system. Utility Model Content

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] Example

[0038] As Figure 1 shown, the bag - type monitoring compensation dust removal system proposed by the utility model includes a bottom plate 1, a vacuum pump 2 installed on the bottom plate 1. The air inlet end of the vacuum pump 2 is connected with a connecting pipe 21. The connecting pipe 21 is used to connect the vacuum pump 2 and the dust removal module 3 to ensure that gas can be stably transported to the vacuum pump 2 for subsequent processing.

[0039] Furthermore, please refer to Figures 1 to 3 , the above - mentioned dust removal system includes a dust removal module 3 connected to the end of the connecting pipe 21 far from the vacuum pump 2. Four groups of dust removal bags 4 are arranged in the dust removal module 3 to filter gas. The dust removal module 3 includes a fixed box 31, and a side cover 32 is installed on the side of the fixed box 31. The fixed box 31 and the side cover 32 are connected by bolts and nuts, and a sealing rubber ring is arranged at the connection position. This connection method ensures the tightness of the filter cavity, allowing air to enter through the only inlet and exit through the only outlet. At the same time, the inlet and outlet positions correspond, facilitating the rapid flow of air and passing through the filtration of the dust removal bags 4. The four groups of dust removal bags 4 are all located in the filter cavity formed between the fixed box 31 and the side cover 32. An air inlet pipe 33 is installed on the side of the fixed box 31 far from the vacuum pump 2. Both the air inlet pipe 33 and the connecting pipe 21 are connected to the filter cavity, and the air inlet pipe 33 and the connecting pipe 21 are coaxial, facilitating air to directly pass through the dust removal bags 4 between the air inlet pipe 33 and the connecting pipe 21. The dust in the gas is efficiently filtered through the dust removal bags 4 to ensure that the purified gas meets the emission requirements. One end of the suction pipe 6 is sleeved on the air inlet pipe 33. After the vacuum pump 2 is started, external gas sequentially passes through the suction pipe 6, the air inlet pipe 33, and the connecting pipe 21 and enters the vacuum pump 2. The sleeved connection method of the suction pipe 6 and the air inlet pipe 33 is convenient for disassembly and installation, facilitating equipment maintenance. A fixed frame 34 is installed on the top of the bottom plate 1. The fixed frame 34 is set in a "冂" shape. The fixed box 31 is fixed to the bottom of the fixed frame 34 through a mounting bracket, making the position of the fixed box 31 stable and effectively preventing the dust removal module 3 from shaking during operation and affecting the dust removal effect.

[0040] Even further, as Figures 2 to 5As shown, the dust removal system also includes a fixing component 5 installed in the dust removal module 3. The fixing component 5 is used to fix four sets of dust collector bags 4. The fixing component 5 includes a rotating sleeve 51 rotatably connected to the fixing box 31. The two ends of the rotating sleeve 51 are interference-fitted with the fixing box 31 to increase the friction when the rotating sleeve 51 and the rotating shaft 71 rotate, thereby preventing the helical gear 72 from rotating in the opposite direction and ensuring the stability of the fixing component 5 during operation. An installation frame 52 is installed on the outer ring of the rotating sleeve 51. Multiple sets of installation rings 53 are connected to the rotating sleeve 51 through the installation frame 52. When the rotating sleeve 51 rotates, it drives the installation rings 53 to perform circumferential motion through the installation frame 52, thereby switching the position of the dust collector bags 4. The number of installation rings 53 corresponds to the number of dust collector bags 4. A retaining ring 54 is fixedly connected to the side of the installation ring 53 away from the air inlet pipe 33. The retaining ring 54 has a right-angled triangular cross section. One end of the dust collector bag 4 is fitted onto the outer ring of the retaining ring 54 and contacts the inclined surface of the retaining ring 54. This structural design can play a preliminary positioning role for the dust collector bags 4. A pressure ring 55 is provided on the side of the retaining ring 54 away from the mounting ring 53. When the pressure ring 55 approaches the mounting ring 53, it works with the retaining ring 54 to squeeze one end of the dust collector bag 4, thus firmly fixing the dust collector bag 4 and preventing it from falling off during filtration. Multiple sets of first connecting blocks 56 are fixedly connected to the outer ring of the pressure ring 55. A screw 57 is threaded through each first connecting block 56, and one end of the screw 57 is threaded to a second connecting block 58. All sets of second connecting blocks 58 are fixedly connected to the outer ring of the mounting ring 53. When the screw 57 is tightened, the pressure ring 55 approaches the retaining ring 54 to squeeze and fix the dust collector bag 4. This adjustable connection method facilitates the installation and removal of dust collector bags 4 of different specifications.

[0041] Furthermore, the dust removal system also includes a suction pipe 6 connected to the side of the dust removal module 3. The suction pipe 6 can be a flexible hose such as a corrugated pipe to improve the flexibility of suction and adapt to the gas suction needs under different working conditions.

[0042] For details, please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 6The dust removal system also includes a replacement mechanism 7 installed in the dust removal module 3. The replacement mechanism 7 is used to switch the filter bags 4. The replacement mechanism 7 includes a rotating shaft 71 fixedly connected to a rotating sleeve 51. When the rotating shaft 71 rotates, it drives the rotating sleeve 51 to rotate, providing power transmission for switching the filter bags 4. One end of the rotating shaft 71 is rotatably connected to the fixed box 31, and the rotating shaft 71 remains in its original position to ensure rotational stability. The other end of the rotating shaft 71 passes through the fixed box 31 and is fitted with a helical gear 72. When the helical gear 72 rotates, it drives the rotating shaft 71 to rotate, achieving effective power transmission. A helical rack 73 is provided on one side of the helical gear 72, meshing with it in one direction. This ensures that when the helical rack 73 moves, it can only drive the helical gear 72 to rotate in one direction, preventing misoperation during the switching of the filter bags 4. A moving block 74 is slidably connected to the outside of the helical rack 73. When the moving block 74 moves, it drives the helical rack 73 to move synchronously, ensuring accurate transmission. A limiting block 75 is fixedly connected to the outer ring of the helical rack 73. The limiting block 75 is slidably connected to the moving block 74. Multiple sets of limiting rods 76 are fixedly connected to the side of the helical rack 73 away from the helical gear 72. The limiting rods 76 are slidably connected to the moving block 74. Through the setting of the limiting block 75 and the limiting rods 76, the helical rack 73 slides smoothly in the moving block 74, improving the reliability of the replacement mechanism 7. A spring 77 is sleeved on the outer ring of the limiting rod 76. The elastic force of the spring 77 keeps the helical rack 73 in contact with the helical gear 72. When the helical rack 73 moves in a direction that can drive the helical gear 72 to rotate, the spring 77 ensures that the helical rack 73 meshes with the helical gear 72. When the helical rack 73 moves in a direction that cannot drive the helical gear 72 to rotate, the helical rack 73 slides into the moving block 74 under the influence of the inclined surface of the helical gear 72, while simultaneously compressing the spring 77. The elastic force of the spring 77 facilitates the reset of the helical rack 73, ensuring the stable cyclic operation of the replacement mechanism 7. The replacement mechanism 7 also includes a push rod motor 78 installed on the side of the fixed box 31. The output end of the push rod motor 78 is fixedly connected to the moving block 74. After the push rod motor 78 is started, it drives the moving block 74 to move, thereby driving the helical rack 73 to move, providing stable power for the switching of the dust collector bag 4. Two sets of sliding rods 79 are fixedly connected to the end of the moving block 74 away from the push rod motor 78. Sliding sleeves 710 are slidably connected to the sliding rods 79 and are fixedly connected to the fixed box 31. The position of the sliding sleeves 710 is fixed, and they work with the sliding rods 79 to limit the movement of the moving block 74, ensuring smooth movement and further improving the operating accuracy of the replacement mechanism 7. A spring-loaded sensor 711 is installed between the two sets of sliding rods 79 on the side of the fixed box 31. When the moving block 74 contacts the spring-loaded sensor 711, it sends a signal, allowing the push rod motor 78 to be stopped to prevent excessive extension. Simultaneously, it records that the dust collector bag 4 has been replaced, thus automating the dust collector bag 4 replacement process.

[0043] Furthermore, such as Figure 1 and Figure 2 As shown, the dust removal system also includes a sensing component 8 installed in the connecting pipe 21. The sensing component 8 is used to determine whether the dust collector bag 4 needs to be replaced. The sensing component 8 includes a hollow monitoring box 81 installed in the connecting pipe 21. The monitoring box 81 is fixed by a mounting bracket to ensure the stability of the sensing component 8. The connecting pipe 21 is connected to the monitoring box 81. A rotating rod 82 is rotatably connected in the monitoring box 81. A connecting plate 83 is fixedly connected to the outer ring of the rotating rod 82. The rotating rod 82 is connected to multiple rotating parts 84 through multiple sets of connecting plates 83. The rotating parts 84 are bowl-shaped. The axis of the connecting pipe 21 is tangent to the circular motion trajectory of the center of the rotating parts 84. This allows the airflow flowing towards the vacuum pump 2 through the connecting pipe 21 to directly impact the rotating parts 84 after the vacuum pump 2 is started, thereby driving the multiple rotating parts 84 to perform circular motion. The rotation speed of the rotating rod 82 reflects the flow velocity in the connecting pipe 21, thus accurately determining the ventilation rate of the dust collector bag 4 and providing a reliable basis for replacing the dust collector bag 4. One end of the rotating rod 82 passes through the monitoring box 81. A speed sensor 85 is installed on the side of the monitoring box 81 through which the rotating rod 82 passes. The speed sensor 85 monitors the rotation speed of the rotating rod 82 in real time to ensure the timeliness and accuracy of the judgment.

[0044] Finally, the aforementioned dust removal system also includes a control box 9 installed on the top of the base plate 1. The vacuum pump 2, push rod motor 78, spring-loaded sensor 711, and speed sensor 85 are all electrically connected to the control box 9, which controls the start and stop of the vacuum pump 2 and push rod motor 78. When the rotation speed of the rotating rod 82 detected by the speed sensor 85 is lower than the preset value, the vacuum pump 2 is briefly stopped, and the push rod motor 78 is extended. After the spring-loaded sensor 711 is triggered, it receives a signal to stop the extension operation of the push rod motor 78, and the vacuum pump 2 is restarted, realizing the automatic replacement of the dust collector bag 4 without manual intervention, which greatly improves the automation level and operating efficiency of the dust removal system. After the spring-loaded sensor 711 is triggered three times, the spare dust collector bags 4 in the dust removal module 3 are all used up. The remote control module in the control box 9 sends a warning signal to the control console, or sends a warning signal through the warning light and buzzer to remind the staff to remove the side cover 32 in time to replace the dust collector bags 4, ensuring the continuous and stable operation of the dust removal system.

[0045] In this embodiment, after the vacuum pump 2 is started, the outside gas enters the filter chamber of the dust removal module 3 through the suction pipe 6 and the air inlet pipe 33 in sequence under its suction force. After being filtered by the dust removal bag 4, the dust is intercepted on the surface of the bag. The purified gas enters the vacuum pump 2 through the connecting pipe 21 to complete the dust removal process.

[0046] During operation, the rotating part 84 inside the monitoring box 81 is driven by the airflow to rotate the rotating rod 82, and the speed sensor 85 monitors its speed in real time. When the dust collector bag 4 accumulates too much dust, resulting in a decrease in the air intake, the airflow velocity in the connecting pipe 21 decreases, and the speed of the rotating rod 82 decreases accordingly. When the speed is lower than the preset value, the speed sensor 85 transmits a signal to the control box 9. After receiving the signal, the control box 9 first controls the vacuum pump 2 to pause briefly, and then starts the push rod motor 78. The push rod motor 78 drives the moving block 74 to move, and the moving block 74 drives the helical rack 73 to move through the limit block 75 and the limit rod 76. The helical rack 73 meshes with the helical gear 72 in one direction, driving the helical gear 72 to rotate, which in turn causes the rotating shaft 71 and the rotating sleeve 51 to rotate. The rotating sleeve 51 drives the mounting ring 53 to perform circumferential motion through the mounting frame 52, realizing the switching of the dust collector bag 4, removing the blocked bag, and using a new bag to continue filtering. When the moving block 74 triggers the spring-loaded sensor 711, the sensor sends a signal to the control box 9. The control box 9 then controls the push rod motor 78 to stop extending and restarts the vacuum pump 2 to resume dust removal. Afterwards, the push rod motor 78 retracts, and the helical rack 73 slides into the moving block 74 under the influence of the inclined surface of the helical gear 72, simultaneously compressing the spring 77. The spring force of the spring 77 facilitates the reset of the helical rack 73, ensuring the stable cyclic operation of the replacement mechanism 7.

[0047] When the spring-loaded sensor 711 is triggered three times, it means that all the spare dust collector bags 4 in the dust removal module 3 have been used. At this time, the control box 9 sends a warning signal to the control console through the remote control module, or reminds the staff through the warning light and buzzer, that the side cover 32 needs to be removed to replace the dust collector bags 4 as a whole, so as to ensure the continued stable operation of the dust removal system.

[0048] The above specific embodiments are merely optional embodiments of this utility model.
