Description

Technical Field

[0001] This utility model relates to the technical field of baghouse dust collectors, specifically a combined baghouse dust collector with multi-directional access and equal flow. Background Technology

[0002] Common baghouse dust collectors often employ a single-inlet design, with dust-laden gas entering from a single direction. This causes the airflow inside the collector to concentrate in the area near the inlet, making it difficult to evenly diffuse throughout the entire filtration space. This uneven airflow distribution results in significant differences in the airflow impact experienced by the filter bags within the filtration area. Filter bags near the inlet are subjected to constant scouring by high-speed airflow, leading to severe wear of the filter media and premature damage or perforation. This greatly shortens the service life of the filter bags and increases the frequency of replacement and maintenance costs. Meanwhile, filter bags farther from the inlet suffer from insufficient filtration load due to the difficulty in reaching them with airflow. Consequently, the overall filtration capacity of the equipment is not fully utilized, resulting in low dust collection efficiency. Utility Model Content

[0003] The purpose of this invention is to solve the problem that the dust-laden airflow is concentrated near the inlet in the single-inlet design of common baghouse dust collectors, making it difficult to diffuse evenly. This invention provides a combined baghouse dust collector with multi-directional access and flow equalization.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A multi-directional access and flow equalization combined baghouse dust collector includes a dust collector housing. An inlet pipe is installed through the upper left sidewall of the dust collector housing. A filter pipe is fixedly connected to the inlet pipe inside the dust collector housing. An airflow equalization pipe is installed around the sidewall of the filter pipe. Multiple sets of airflow equalization pipes are arranged evenly. A tube sheet is installed below the airflow equalization pipes. A funnel is fixedly connected to the bottom side of the tube sheet. A dust removal assembly is installed on the front and rear sides of the bottom of the funnel. The dust removal assembly includes a rotary motor, a rotating shaft, and a rotating plate. The dust removal assembly penetrates the sidewall of the dust collector housing. A dust collector bag is fixedly connected to the bottom of the funnel. The inner sidewall of the dust removal assembly is rotatably connected to the front and rear outer sidewalls of the dust collector bag. A dust discharge assembly is installed at the bottom of the dust collector housing, directly below the dust collector bag.

[0006] Furthermore, a gas conveying component is provided on the side wall of the ash discharge component, a clean air chamber is provided on the right side inside the dust collector housing, the top outlet of the gas conveying component is connected to the bottom of the clean air chamber, an exhaust port is provided at the top right end of the clean air chamber, a controller is provided on the left side of the dust collector housing, and a bracket is fixedly connected to the bottom of the dust collector housing.

[0007] Furthermore, the sidewall of the rotating plate strikes the outer sidewall of the dust collector bag, causing the dust adhering to the dust collector bag to fall off.

[0008] Furthermore, the output end of the rotary motor is fixedly connected to the left end of the rotating shaft, and the rotating plate is disposed on the side wall of the rotating plate. When the rotary motor is started, its output end drives the rotating shaft to rotate, and the rotating plate on the rotating shaft rotates accordingly.

[0009] Furthermore, the ash discharge assembly includes an ash discharge port and a cover. The cover is movably connected to the bottom side of the ash discharge port. The left end of the gas conveying assembly penetrates the side wall of the ash discharge port. When ash discharge is required, the cover is opened, and the dust can be discharged from the dust collector through the ash discharge port.

[0010] Furthermore, the gas delivery assembly includes a gas delivery pipe and an exhaust fan. The exhaust fan is located at the right end of the gas delivery pipe, and the top outlet of the right end of the gas delivery pipe is connected to the bottom inlet of the clean air chamber. When the exhaust fan in the gas delivery assembly is activated, clean gas will enter the clean air chamber through the gas delivery pipe.

[0011] Furthermore, an inspection assembly is provided on the top of the dust collector housing. The inspection assembly includes an inspection cover and a pressure sensor. The pressure sensor is located on the left side of the top inside the dust collector housing. The movable cover of the pressure sensor is connected to the top left end of the dust collector housing for real-time monitoring of the pressure changes inside the dust collector.

[0012] Compared with the prior art, this utility model provides a combined bag filter dust collector with multi-directional access and flow equalization, which has the following beneficial effects:

[0013] This multi-directional, flow-equalizing combined baghouse dust collector effectively filters large particles and ensures the safe operation of downstream equipment through gas introduction and distribution. It also provides an efficient channel for gas entry. Multiple sets of airflow distribution pipes, evenly arranged around the sidewalls of the filter tubes, overcome the limitations of traditional single-inlet airflow, which tends to concentrate and distribute unevenly. This allows dust-laden gas to enter the filtration area comprehensively and evenly, greatly improving filtration efficiency. It avoids premature wear or insufficient filtration of localized filter bags due to excessive or insufficient airflow impact, extending the overall filtration system's lifespan, significantly improving dust collection efficiency and quality, enhancing equipment stability, and reducing maintenance costs.

[0021] 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. Example:

[0022] like Figures 1-6As shown, a multi-directional access and flow equalization combined baghouse dust collector includes a dust collector housing 1. An inlet pipe 2 is installed through the upper left side wall of the dust collector housing 1. A filter pipe 3 is fixedly connected to the inlet pipe 2 inside the dust collector housing 1. Airflow equalization pipes 4 are installed around the side wall of the filter pipe 3. Multiple sets of airflow equalization pipes 4 are arranged evenly. A tube sheet 5 is installed below the airflow equalization pipes 4. A funnel 6 is fixedly connected to the bottom side of the tube sheet 5. Cleaning components 7 are installed on the front and rear sides of the bottom of the funnel 6. The cleaning components 7 penetrate the side wall of the dust collector housing 1. A dust collector bag is fixedly connected to the bottom of the funnel 6. 8. The inner side wall of the dust removal component 7 is rotatably connected to the front and rear outer side walls of the dust collector bag 8. The bottom of the dust collector housing 1 is located directly below the dust collector bag 8 and a dust discharge component 9 is provided. A gas conveying component 10 is provided on the side wall of the dust discharge component 9. A clean air chamber 11 is provided on the right side inside the dust collector housing 1. The top outlet of the gas conveying component 10 is connected to the bottom of the clean air chamber 11. An exhaust port 12 is provided at the top right end of the clean air chamber 11. A controller 13 is provided on the left side of the dust collector housing 1. An inspection component 14 is provided on the top of the dust collector housing 1. A bracket 15 is fixedly connected to the bottom of the dust collector housing 1.

[0023] like Figure 6 As shown, the dust removal assembly 7 includes a rotary motor 701, a rotating shaft 702, and a rotating plate 703. The side wall of the rotating plate 703 beats against the outer side wall of the dust collector bag 8. The output end of the rotary motor 701 is fixedly connected to the left end of the rotating shaft 702. The rotating plate 703 is located on the side wall of the rotating plate 703. When the rotary motor 701 in the dust removal assembly 7 is started, its output end drives the rotating shaft 702 to rotate. The rotating plate 703 on the rotating shaft 702 rotates accordingly. The side wall of the rotating plate 703 continuously beats against the outer side wall of the dust collector bag 8, causing the dust adhering to the dust collector bag 8 to fall off.

[0024] like Figure 3 As shown, the ash discharge assembly 9 includes an ash discharge port 901 and a cover 902. The cover 902 is movably connected to the bottom side of the ash discharge port 901. The left end of the gas conveying assembly 10 passes through the side wall of the ash discharge port 901. When ash discharge is required, the cover 902 is opened, and the dust can be discharged from the dust collector through the ash discharge port 901, thus completing the entire dust collection process.

[0025] The gas delivery assembly 10 includes a gas delivery pipe 1001 and an exhaust fan 1002. The exhaust fan 1002 is located at the right end of the gas delivery pipe 1001. The top outlet of the right end of the gas delivery pipe 1001 is connected to the bottom inlet of the clean air chamber 11. When the exhaust fan 1002 in the gas delivery assembly 10 is started, clean gas will enter the clean air chamber 11 through the gas delivery pipe 1001.

[0026] like Figure 5As shown, the inspection component 14 includes an inspection cover 1401 and a pressure sensor 1402. The pressure sensor 1402 is located on the top left side of the dust collector housing 1. The movable cover of the pressure sensor 1402 is connected to the top left end of the dust collector housing 1. It is used to monitor the changes in air pressure inside the dust collector in real time. When the air pressure is abnormal, it may indicate that the dust collector bag 8 is blocked or other components are malfunctioning. At this time, the inside of the dust collector can be inspected and repaired by opening the inspection cover 1401.

[0027] Working principle: such as Figures 1-6 As shown, the dust-laden gas is introduced and evenly distributed: the dust-laden gas enters the dust collector through the inlet pipe 2 on the upper left side wall of the dust collector shell 1. The inlet pipe 2 is connected to the filter pipe 3. After entering the filter pipe 3, the dust-laden gas is introduced from multiple directions through multiple sets of airflow distribution pipes 4 evenly arranged around its side wall. The function of the airflow distribution pipes 4 is to make the dust-laden gas evenly distributed in the dust collector, avoid local airflow speeds that are too fast or too slow, thereby improving the subsequent dust removal effect.

[0028] Dust removal process: The dust-laden gas flows downward to the tube sheet 5 after being uniformly distributed. The tube sheet 5 acts as a separator, allowing the gas to pass only through the dust collector bags 8 below it. When the dust-laden gas passes through the filter bags, the dust is trapped on the side wall of the dust collector bags 8. The exhaust fan 1002 in the gas conveying assembly 10 is started, and the clean gas will enter the clean air chamber 11 through the gas conveying pipe 1001.

[0029] Clean gas discharge: The clean gas after dust removal is collected in the clean air chamber 11 and then discharged from the dust collector through the exhaust port 12 at the top right end of the clean air chamber 11.

[0030] Dust removal process: As the dust removal process proceeds, dust will gradually accumulate on the side wall of the dust collector bag 8. At this time, the dust removal assembly 7 starts to work; the rotary motor 701 in the dust removal assembly 7 starts, and its output end drives the rotating shaft 702 to rotate. The rotating plate 703 on the rotating shaft 702 rotates accordingly. The side wall of the rotating plate 703 continuously beats the outer side wall of the dust collector bag 8, causing the dust attached to the dust collector bag 8 to fall off. The fallen dust falls into the dust discharge assembly 9 below.

[0031] Ash removal process: Ash removal component 9 includes ash removal port 901 and cover 902. When ash removal is required, the cover 902 is opened and the dust can be discharged from the dust collector through the ash removal port 901, thus completing the entire dust collection process.

[0032] Monitoring and maintenance: During the operation of the dust collector, the inspection component 14 plays a monitoring and maintenance role. The air pressure sensor 1402 is set on the top left of the inside of the dust collector housing 1 to monitor the air pressure changes inside the dust collector in real time. When the air pressure is abnormal, it may indicate that the dust collector bag 8 is blocked or other components are malfunctioning. At this time, the inside of the dust collector can be inspected and repaired by opening the inspection cover 1401.

[0033] Equipment control: The operation of various components of the dust collector (such as the rotary motor 701, the exhaust fan 1002, etc.) is controlled and coordinated by the controller 13 on the left side of the dust collector housing 1.
