Description

Technical Field

[0001] This application relates to the field of bag filter cleaning technology, and in particular to a mobile pulse cleaning device for bag filters. Background Technology

[0002] Based on the filtration direction of the filter bags, baghouse dust collectors can be divided into two categories: internal filtration and external filtration. In external filtration dust collectors, dust-laden gas flows from the outside of the filter bag to the inside, with dust trapped on the outer surface of the bag, while clean gas escapes through the gaps in the bag. Over time, the dust layer on the outer surface of the filter bag thickens, increasing the resistance and reducing the airflow capacity. At this point, cleaning is necessary.

[0003] The current dust removal methods in the industry mainly rely on pulse-jet cleaning. Depending on the arrangement of the filter bags, a certain number of air manifolds, pulse valves, and pulse tubes are required. The larger the dust collector, the more air manifolds, pulse valves, and pulse tubes are needed, significantly increasing production costs. Furthermore, replacing the filter bags requires removing the pulse tubes, causing considerable inconvenience for subsequent filter bag replacements. In other words, the existing dust removal technology has a fixed setup; the larger the dust collector, the more dust removal devices need to be installed. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] The following is in conjunction with the appendix Figure 1-3This application will be further described in detail below. An embodiment of this application discloses a mobile pulse cleaning device for a bag filter. It includes an air reservoir 1, which is connected to a pulse valve (not shown in the figure). The pulse valve is connected to a pulse pipe 2, and air is sprayed through the end port of the pulse pipe 2 to clean the filter bags of the bag filter.

[0024] An air tank 1 is connected to a motor 3, which in turn is connected to a drive shaft 4. Rollers 5 are connected to both ends of the drive shaft 4. Two tracks 6 are provided corresponding to the two rollers 5. Each track 6 is equipped with a workstation positioning device 7. The air tank 1 is connected to a workstation monitoring device 8 that monitors the workstation positioning device 7. In such cases… Figure 1 In the illustrated embodiment, track 6 is positioned above the bag filter, and the track 6 determines the direction or position of movement of roller 5. The relative position of track 6 to the bag filter is determined by station positioning device 7, and the relative position of air tank 1 to the bag filter is determined by station monitoring device 8 monitoring station positioning device 7. Finally, the position of pulse tube 2 relative to the bag filter is determined. By connecting motor 3, station monitoring device 8, and external processing core electrical signals, the position of pulse tube 2 relative to the bag filter can be automatically determined, and then motor 3 can control the movement of pulse tube 2 relative to the bag filter.

[0025] Furthermore, the workstation positioning device 7 and the workstation monitoring device 8 can be any conventional existing equipment. In this embodiment, the workstation positioning device 7 is a positioning plate spaced apart along the extension direction of the track 6, and the workstation monitoring device 8 is a proximity switch sensor that probes the workstation positioning plate. The slots created by the spaced arrangement of the positioning plate allow the proximity switch sensor, which serves as the workstation monitoring device 8, to detect both slotted and non-slotted monitoring information. One of the monitoring information is set as the workstation information for the pulse tube 2 to perform the dust removal operation, based on the actual situation. By reasonably setting the slots of the positioning plate, for example, with each slot corresponding to a workstation position requiring dust removal, the air tank 1 can determine, through the workstation monitoring device 8, that it has reached the dust removal workstation when it moves to the slot position of the positioning plate, and then perform dust removal through the pulse tube 2.

[0026] Furthermore, the positioning plate of the workstation positioning device 7 can be set at any position relative to the track 6. When the positioning plate is set above the track 6, in order to prevent the positioning plate from obstructing the rotation of the roller 5, the distance between the workstation positioning device 7 and the track 6 is greater than the diameter of the roller 5.

[0027] Furthermore, when the location of the workstation positioning device 7 is not convenient for the workstation monitoring device 8, which is directly connected to the air tank 1, the workstation monitoring device 8 is connected to the air tank 1 through the workstation monitoring bracket, and the workstation monitoring device 8 is extended to a location that is convenient for monitoring the workstation positioning device 7.

[0028] Furthermore, it also includes a derailment positioning device 9 and a derailment monitoring device 10. The derailment positioning device 9 is a straight plate arranged along the extension direction of the track 6, and the derailment monitoring device 10 is a proximity switch sensor that detects the straight plate. By using the proximity switch sensor, which functions as the derailment monitoring device 10, to detect the straight plate, which functions as the derailment positioning device 9, a definite monitoring information is obtained as the on-track information. When the derailment monitoring device 10 detects monitoring information that does not conform to the on-track information, it can determine that the roller 5 has derailed from the track 6. Combined with the externally connected processing core, it can control the motor 3 to stop or issue an alarm, etc.

[0029] Furthermore, the position of the straight plate, which serves as the derailment positioning device 9, can be set at any position relative to the track 6. When the straight plate is set above the track 6, in order to prevent the straight plate from obstructing the rotation of the roller 5, the distance between the derailment positioning device 9 and the track 6 is greater than the diameter of the roller 5.

[0030] Furthermore, when the location of the derailment positioning device 9 is not convenient for the derailment monitoring device 10, which is directly connected to the air tank 1, to detect it, the derailment monitoring device 10 is connected to the air tank 1 through a derailment monitoring bracket, and the derailment monitoring device 10 is extended to a location that is convenient for monitoring the derailment positioning device 9.

[0031] Furthermore, the rollers 5 and the track 6 can also be conventional, existing equipment. In this embodiment, the rolling surfaces of the rollers 5 are all provided with teeth, and the track 6 is a rack that meshes with the teeth of the rollers 5. The rack divides the overall length of the track 6 into equal segments, and while the teeth of the rollers 5 precisely control the movement distance, the meshing state of the teeth and the rack also keeps the air bag 1 in a fixed state relative to the track 6, preventing slippage or other situations that may lead to displacement.

[0032] Furthermore, the pulse tube 2 includes a pulse main tube, which is provided with one or more pulse nozzles, thereby expanding the working area for dust removal by providing more pulse nozzles.

[0033] Furthermore, limiting devices are provided at both the beginning and end of track 6 to prevent the roller 5 from moving out of the track 6's range. These limiting devices can be independent. For example, baffles can be installed at the beginning and end of track 6 to directly block the roller 5's movement, thus preventing the motor 3 from rotating. When the motor 3 stops rotating, it is determined that the air tank 1 has moved to the end of track 6. Alternatively, proximity switch sensors that can be electrically connected to the motor 3 can be installed at the beginning and end of track 6. When the air tank 1 moves to the end of track 6, the proximity switch sensor detects the signal from the air tank 1, indicating that the air tank 1 has moved to the end of track 6. The limiting devices can also be used in conjunction with other monitoring devices, such as... Figure 2In the illustrated embodiment, the positioning plate of the workstation positioning device 7 and the straight plate of the derailment positioning device 9 are the same plate, and the workstation monitoring device 8 and the derailment monitoring device 10 are both mounted on the same bracket. The workstation monitoring device 8 determines the dust removal workstation by monitoring the workstation positioning device 7, and the derailment monitoring device 10 monitors the derailment positioning device 9 to determine whether the roller 5 has disengaged from the track 6. The bracket is also connected to two proximity switch sensors as limit devices, serving as a track head limit device for monitoring the head end of the track 6 and a track end limit device for monitoring the tail end of the track 6. Corresponding monitored structures are set at the head and tail ends of the track 6. When the head limit device detects the monitored structure at the head end of the track 6, it can determine that the air tank 1 has moved to the head end of the track 6; when the tail limit device detects the monitored structure at the tail end of the track 6, it can determine that the air tank 1 has moved to the tail end of the track 6.

[0034] Working Principle: The pulse valve, motor 3, and station monitoring device 8 are electrically connected to the processing core or manual controller. The track 6 is positioned above the bag filter, and the rollers 5 are placed on the track 6. A preset program is set in the processing core or manual controller, including signals to start the station monitoring device 8 corresponding to the pulse valve, the preset duration of pulse valve start, and signals to start and stop the motor 3 corresponding to the station monitoring device 8. For example, when the proximity switch sensor acting as the station monitoring device 8 detects the set dust removal station information, the motor 3 stops. At this time, the processing core automatically starts the pulse valve spraying for the preset time, or the manual controller actively starts the pulse valve spraying for the preset time. After the pulse valve spraying is completed, the processing core automatically or the manual controller actively starts the motor 3 to continue moving the air tank 1 until the station monitoring device 8 detects the next stop signal. When the rollers 5 disengage from the track 6, the derailment monitoring device 10 will detect the derailment signal and can issue an alarm for timely manual handling or control the motor 3 to stop through the preset program built into the processing core.
