Description

Technical Field

[0001] The present application relates to the field of dust removal, and in particular to a filter bag dust collector with a damage alarm function and easy to maintain. Background Art

[0002] The filter bag dust collector is a common dust removal equipment, which mainly relies on the filter bag for dust removal. The airflow containing dust enters from the opening of the filter bag and comes out of the bag tube of the filter bag, which is called internal filtration, or enters from the bag tube of the filter bag and comes out of the opening of the filter bag, which is called external filtration, thereby achieving dust removal of the airflow. Based on this dust removal method, the wind-exposed area of the filter bag and the material of the filter bag itself play a decisive role in the dust removal effect. In addition, since the operating environment of the dust filter bag is often high temperature, and some are charged airflow environments, the environment in which the filter bag is actually located is very harsh. The filter bag needs to be cleaned after a period of use, and some need to be replaced and maintained. If the filter bag is damaged, the dust removal effect will be greatly reduced, causing air pollution. However, the existing filter bag dust collector is generally not easy to repair when the device is not turned on. Therefore, the following situation may occur: a filter bag is actually damaged, but it is not discovered in time. When it is next inspected, it is found that the filter bag has been running in a damaged state for a long time. Because the time interval between manual inspections is often relatively long, the actual use effect of the dust filter bag is actually relatively poor, and even the air after actual dust removal does not meet the emission standards at all. Summary of the Invention

[0003] Purpose of the invention: This application aims to overcome the defects of the prior art and provide a filter bag dust collector that is easy to maintain and has a damage alarm function.

[0004] Technical solution: A filter bag dust collector comprises an upper base plate, a lower base plate and multiple dust filter bags, the upper base plate has multiple upper filter bag mounting holes, the lower base plate has multiple lower filter bag mounting holes, the number of upper filter bag mounting holes, lower filter bag mounting holes and dust filter bags is equal, each dust filter bag passes through an upper filter bag mounting hole and a lower filter bag mounting hole; the dust filter bag comprises a cage frame and a filter bag unit, the cage frame comprises multiple support rings and multiple vertical rods, the top of each vertical rod is fixed with an end support block, the filter bag unit comprises a bag barrel and a circular folded edge at the top of the bag barrel, each upper filter bag mounting hole is installed with a circular pressure ring, and the circular folded edge is pressed between the upper base plate and the corresponding pressure ring.

[0005] Therefore, the dust filter bag and the upper base plate are easy to disassemble and assemble, and the lower base plate makes the installation of the dust filter bag more stable due to the limitation of the lower filter bag installation hole, and ensures that the detection space formed by the upper base plate and the lower base plate is clean.

[0006] Furthermore, a sealing ring is fixed at the lower filter bag installation hole, and the sealing ring abuts and seals against the outer side wall of the bag tube.

The circular ring portion 6.3.2 and the plurality of spacers 6.3.1 of the sealing gasket unit 6.3 are integrally formed. The sealing gasket unit 6.3 has six spacers 6.3.1.

[0046] As shown in the figure, the filter bag of the present application is mounted on the upper base plate, and the lower base plate and the dust filter bag are sealed against each other, limiting the position of the dust filter bag. This prevents the dust filter bag from tilting even in strong airflow, minimizing the impact on the dust filter bag. Furthermore, the upper base plate, lower base plate, and surrounding frame form a clean detection space.

[0047] The detection principle is as follows: air flows from around the bag tube into the filter bag. After dust removal, clean air exits the opening of the dust filter bag. A portion of this airflow enters the detection box and impacts one of the detection areas of the detection disc. In theory, since the airflow impacting the detection area is clean, it will cause little contamination to the detection area. However, if the dust filter bag is damaged, the air will not be clean, which will contaminate the detection area. Images captured by the image acquisition device can be used to determine whether the filter bag is damaged. Furthermore, during actual dust removal, the airflow passing through the filter bag is not 100% clean and still contains a certain amount of dust, which will actually contaminate the detection area. Over time, the actual duration that each detection area can be used for detection is limited. After a period of time, the detection area is effectively unusable. Therefore, the detection disc of the present application actually has six detection areas, which are allocated to each group of two dust filter bags. Each dust filter bag corresponds to three detection areas. Thus, the three detection areas are used in sequence. When one detection area becomes unusable, the next detection area is used. This allows a detection disc to be used for a long time without replacement.

[0048] More specifically, the motor drives the screw to rotate, thereby driving the slide to rotate, and the rack of the slide drives the gear to rotate, thereby driving the detection disc to rotate, and the rotation of the driving gear drives another slide to rotate, thereby driving each detection area of the rotating disc to be located at the corresponding detection box position. And the filter bag dust collector of the present application, during non-detection time, such as Figure 2 As shown, each sealing plate seals the detection box, so that the airflow is blocked by the sealing plate and will not pollute the detection area. When detection is required, first, an image is collected to obtain an image of the detection area to be used; then, as shown in FIG. Figure 3 As shown, open the closing plate, then Figure 4 As shown, when the closing plate is open, continue to drive the screw rod to rotate the detection area required by the detection disc into the detection box (at this time, the side plate of the detection box abuts against the end limit plate and cannot move, but the slide plate can still slide, but the spring on one side is stretched and the spring on the other side is compressed. The continued sliding of the slide plate can drive the gear to rotate, thereby driving the detection disc to rotate), and keep the detection area used in the detection box after the set time; Figure 5As shown, the slide can be made to slide so that the closing plate is closed, and when the closing plate is closed, the detection area just used is rotated to the position for image acquisition (preferably the same as the position for the initial image acquisition (at this time, the slider is abutting the side plate of the detection box and is limited and cannot move, but the slide can still continue to slide, but the spring on one side is stretched and the spring on the other side is compressed. The continued sliding of the slider can drive the gear to rotate, thereby driving the detection disc to rotate). Therefore, by having springs on both sides of the above-mentioned slider, the closing plate can be limited by the end limiting plate and the slider, so that after the closing plate is limited, the slider can still slide, thereby driving the detection area used on the detection disc to be located in the detection box for detection, or to be located at the image acquisition position for image acquisition. The design is more reasonable, so that the closing plate can close the detection box when the detection box does not need airflow to impact the detection area. Although the present invention is illustrated and described with respect to the preferred embodiment, those skilled in the art should understand that various changes and modifications can be made to the present invention as long as they do not exceed the scope defined by the claims of the present invention.
