Description

Technical Field

[0001] This utility model relates to a fault detection device, and more particularly to a fault detection device for a dust collector pulse valve. Background Technology

[0002] A baghouse dust collector is a highly efficient gas purification device that primarily uses filter cloth to capture solid particles from dust-laden gas. During the dust collection process, dust-laden gas enters the dust collector, where dust particles are intercepted, adsorbed, or deposited by the fibers on the filter cloth surface. The purified gas then passes through the filter cloth and is discharged. Baghouse dust collectors offer advantages such as high dust collection efficiency, strong adaptability, and stable operation, and are widely used in dust control across various industrial sectors.

[0003] After prolonged operation, dust accumulates thicker and thicker on the filter cloth of a baghouse dust collector, increasing the resistance to airflow and affecting the normal operation of the device. Therefore, the filter cloth needs to be cleaned regularly. The common cleaning method is pulse cleaning. However, when this method malfunctions, workers need to check the condition of each pulse valve one by one until the faulty pulse valve is found. This increases the maintenance burden on workers, consumes a lot of time, and seriously affects the progress of the filtration work.

[0004] Therefore, it is necessary to design a fault detection device for dust collector pulse valves. Utility Model Content

[0005] In order to overcome the shortcomings of traditional baghouse dust collectors, which cannot quickly diagnose faulty pulse valves and rely heavily on manual inspection, resulting in low efficiency, the purpose of this utility model is to provide a dust collector pulse valve fault detection device.

[0006] The technical solution of this utility model is as follows: a dust collector pulse valve fault detection device, including a housing, a controller, an air inlet, a blower air manifold, a pressure sensor, a pulse valve, a blower pipe, and a purification mechanism. The housing is equipped with a purification mechanism for filtering dust gas. A blower pipe is fixedly connected inside the housing. A blower air manifold is installed on one side of the housing. An air inlet is provided at the bottom of the blower air manifold. A pulse valve is provided at the air outlet of the blower air manifold. One end of the pulse valve extends into the housing and is connected to the blower pipe. A pressure sensor is installed at one end of the blower air manifold. The sensing end of the pressure sensor extends into the blower air manifold. A controller is fixedly connected to one side of the housing. The controller is electrically connected to the pressure sensor and the pulse valve.

[0007] In one embodiment, the air purification mechanism includes an air inlet pipe, a dust discharge port, an air outlet pipe, and a filter bag. An air inlet pipe is fixedly connected to one side of the housing, and an air outlet pipe is fixedly connected to the side of the housing opposite to the air inlet pipe. The air inlet pipe is located below the air outlet pipe. A filter bag is movably connected inside the housing via a connecting plate, and a dust discharge port is provided at the bottom of the housing.

[0008] In one embodiment, a signal light is mounted on top of the controller and is electrically connected to the controller.

[0009] In one embodiment, an access port is provided on the top of the housing, and an access door for sealing the access port is movably connected to the access port.

[0010] In one embodiment, one end of the air intake pipe extends into the machine housing and is fixedly connected to an ash hopper, and a swirl plate is rotatably connected inside the ash hopper.

[0011] In one embodiment, an electrically controlled valve for opening and closing the ash hopper neck is installed at the hopper neck.

[0012] The beneficial effects are: 1. This utility model uses a controller to perform two or more consecutive blowing tests on the pulse valve, and by comparing the test data, it can accurately determine whether the pulse valve has a fault, while reducing manual intervention and improving detection efficiency.

[0013] 2. During the testing process, the controller of this utility model issues a warning by activating the signal light, effectively reminding staff to avoid sending dust gas to the dust collector during the testing period, thus ensuring the smooth progress of the testing work and the safety of personnel.

[0014] 3. This utility model uses a swirl plate design to create a spiral flow of dust and gas during the upward process, which increases the contact area between the dust and gas and the filter bag, thereby improving dust removal efficiency and ensuring the quality of dust removal work.

Detailed Implementation

[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] Example: A dust collector pulse valve fault detection device, such as... Figures 1-3 As shown, the device includes a housing 1, a controller 3, an air inlet 8, a blow-through air manifold 9, a pressure sensor 10, a pulse valve 11, a blow-through pipe 12, and a purification mechanism. The housing 1 houses the purification mechanism for filtering dust and gas. The blow-through pipe 12 is fixedly connected inside the housing 1. The blow-through air manifold 9 is installed on one side of the housing 1, with an air inlet 8 at its bottom. A pulse valve 11 is installed at the air outlet of the blow-through air manifold 9, with one end extending into the housing 1 and connected to the blow-through pipe 12. A pressure sensor 10 is installed at one end of the blow-through air manifold 9, with its sensing end extending into the manifold 9. The controller 3 is fixedly connected to one side of the housing 1, and is electrically connected to the pressure sensor 10 and the pulse valve 11. The controller 3 has a detection program that allows it to control each pulse valve 11 to operate independently. By performing two or more consecutive blow-through tests on the pulse valves and comparing the test data, the controller can determine if any pulse valves are faulty.

[0022] like Figures 1-2 As shown, the air purification mechanism includes an air inlet pipe 2, a dust discharge port 5, an air outlet pipe 6, and a filter bag 13. The air inlet pipe 2 is fixedly connected to one side of the housing 1, and the air outlet pipe 6 is fixedly connected to the side of the housing 1 opposite to the air inlet pipe 2. The air inlet pipe 2 is located below the air outlet pipe 6. The filter bag 13 is movably connected inside the housing 1 through a connecting plate. The dust discharge port 5 is opened at the bottom of the housing 1. Here, the dusty air enters the housing 1 from the air inlet pipe 2 and is lifted by its own properties. During the rise, the dusty air passes through the filter bag 13. The filter bag 13 filters the dust in the dusty air, so that the dust in the dusty air adheres to the filter bag 13. Finally, the filtered dusty air is discharged from the air outlet pipe 6.

[0023] like Figures 1-2 As shown, a signal light 4 is installed on the top of the controller 3. The signal light 4 is electrically connected to the controller 3. Here, when the device is performing testing, the controller 3 controls the activation of the signal light 4, which emits a warning light to remind the staff to avoid sending dust gas to the dust collector during the testing period, thus ensuring the stable operation of the testing work.

[0024] like Figures 1-2 As shown, an inspection port is provided on the top of the housing 1, and an inspection door 7 is movably connected to the inspection port of the housing 1 for sealing the inspection port. Here, the design of the inspection door 7 makes it convenient for users to enter the device to replace or repair the cloth bag 13, thereby improving the flexibility and practicality of the device.

[0025] like Figure 4As shown, one end of the air inlet pipe 2 extends into the inside of the housing 1 and is fixedly connected to the dust hopper 15. The dust hopper 15 is rotatably connected to the vortex plate 14. Here, the design of the dust hopper 15 can guide the dust gas, so that the dust gas rises rapidly after entering the inside of the housing 1. At the same time, as the dust gas flows upward, the dust gas drives the vortex plate 14 to rotate, so that the vortex plate 14 agitates the dust gas, causing the dust gas to rise in a spiral, thereby increasing the contact surface between the dust gas and the filter bag 13 and improving the filtration effect of the device.

[0026] like Figure 4 As shown, an electrically controlled valve 16 for opening and closing the neck of the ash hopper 15 is installed at the neck of the ash hopper 15. Here, when cleaning the filter bag 13, the electrically controlled valve 16 is activated, and the electrically controlled valve 16 no longer closes the neck of the ash hopper 15, so that the dust above the ash hopper 15 can fall into the ash discharge port 5 through the neck, preventing dust from accumulating in the dust and avoiding blockage of the air inlet pipe 2.

[0027] This device is used to detect the operating status of the pulse valve of a dust collector. When the pulse valve malfunctions, the device starts and troubleshoots the valve. Air is continuously injected into the jet air manifold 9, creating compressed air within it. Pressure sensor 10 senses the pressure change within the jet air manifold 9 and transmits the data to controller 3. Controller 3 receives the data from pressure sensor 10 and records the pressure value within the jet air manifold 9. Then, controller 3 controls a pulse valve 11 in the dust collector to open, removing the blockage from the jet air manifold 9 and allowing the compressed gas within it to flow through the valve to the corresponding jet pipe 12, thus performing a jetting test. Simultaneously, when controller 3 opens pulse valve 11, pressure sensor 10 again senses the pressure value within the jet air manifold 9 and transmits the data back to controller 3. 3. The controller 3 compares the data obtained from the two tests. If there is no significant change between the two tests, it indicates that the pulse valve 11 may be faulty. The above operation is then repeated to perform a second test on the pulse valve 11. If the result of the second test is the same as the result of the previous test, it proves that the pulse valve 11 is faulty. Subsequently, the controller 3 displays the operating status of the pulse valve 11 on its display screen to help the staff understand the fault situation of the pulse valve 11. When the result of the second test is different from the result of the previous test, the controller 3 repeats the above operation to perform a second comparison. If the comparison result is different, the next comparison is performed until two consecutive comparison results are the same. The controller 3 obtains the final test result based on the test comparison results and displays it to the staff. Then, the subsequent pulse valves 11 are tested one by one according to the above method, thus completing the troubleshooting work of the pulse valve 11.
