Description

Technical Field

[0001] This application relates to the field of bag filter technology, and in particular to an anti-clogging dust removal device for bag filters. Background Technology

[0002] After a baghouse dust collector has been operating for a period of time, the dust layer on the surface of the filter bags thickens, increasing the collector's resistance and reducing its filtration efficiency. A common solution is to use pulse-jet cleaning, injecting high-speed, high-pressure compressed air vertically into the filter bags. This compressed air then back-blown inside the bags, effectively cleaning the surface dust. However, this cleaning method is only effective on the lower and middle parts of the bags. Dust adhering to the base of the bags near the tube sheet is generally difficult to remove completely. Over time, the dust at the base of the bags accumulates, eventually forming a hardened layer. When replacing the bags later, this hardened layer at the base can cause blockages, making it difficult to remove the bags. Sometimes, workers even need to use mechanical methods to destructively pull out the bags, which often damages the bag frame and even the tube sheet of the baghouse dust collector. Utility Model Content

[0003] This application provides an anti-clogging dust removal device for filter bags, which can specifically clean the dust at the base of the filter bags in a baghouse dust collector, making it easier to remove the filter bags and frame and quickly replace the filter bags.

[0004] The above-mentioned objective of this application is achieved through the following technical solution: A bag filter anti-clogging dust removal device includes a device body, an electromagnetic pulse valve is installed at the upper end of the device body, and an air source connector is provided on one side of the device body, through which compressed air can be supplied to the inside of the device body. The lower end of the device body is provided with an air outlet, and a detachable gas nozzle is installed at the air outlet of the device body. The gas nozzle can eject radial airflow; When the electromagnetic pulse valve is activated, it can generate a pulsed airflow through the gas nozzle.

[0005] Furthermore, the gas source connector is a quick-connect type gas source connector.

[0006] Furthermore, the air source connector is connected to the air bag at the top of the bag filter via a flexible rubber hose.

[0007] Furthermore, the diameter of the device body is larger than the diameter of the bag opening, while the diameters of the gas nozzle and the gas outlet are both smaller than the diameter of the bag opening.

[0008] Furthermore, a hand handle is fixedly welded to one of the opposite sides of the upper end of the device body.

[0009] Furthermore, the gas nozzle is connected to the gas outlet via a threaded connection, and an O-ring rubber gasket is provided at the connection between the gas nozzle and the gas outlet for sealing.

[0010] Furthermore, the gas nozzle is conical in shape, smaller at the bottom and larger at the top; the interior of the gas nozzle near its outlet is also conical, but its shape is larger at the bottom and smaller at the top.

[0011] Furthermore, the electromagnetic pulse valve is a right-angle electromagnetic pulse valve.

[0012] In summary, this application includes at least one of the following beneficial technical effects: The dust removal device of this application can introduce compressed air into the device body through an air source connector. Under the control of the electromagnetic pulse valve at the top of the device body, the compressed air can intermittently generate instantaneous high-speed, high-pressure compressed air, which is sprayed radially from the gas nozzle to the root of the filter bag. This causes repeated expansion and contraction changes at the root of the filter bag, thereby promoting the removal of the accumulated dust and ash adhering to the root of the filter bag, so that the filter bag and frame can be easily pulled out from the dust collector tube sheet, and the filter bag replacement operation can be completed quickly. The dust removal device of this application can also be used to clean the root of the dust collector filter bag at irregular intervals, so that the filter bag can restore the overall filtration effect of the filter bag during use.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0017] like Figure 1 and Figure 2 As shown, this application discloses an anti-clogging dust removal device for filter bags, comprising a device body 1, an electromagnetic pulse valve 2 installed at the upper end of the device body 1, an air source connector 3 provided on one side of the device body 1, through which compressed air can be supplied to the inside of the device body 1; an air outlet 4 provided at the lower end of the device body 1, and a gas nozzle 5 detachably installed at the air outlet 4 of the device body 1; the gas nozzle 5 can spray radial airflow; after the electromagnetic pulse valve 2 is activated, a pulse airflow can be generated through the gas nozzle 5.

[0018] In the above embodiments, the electromagnetic pulse valve 2 is prior art. The electromagnetic pulse valve 2 controls the opening and closing of the unloading orifice through a millisecond-level electrical signal, which can change the air pressure on both sides of its internal diaphragm, thereby achieving the instantaneous blowing effect of high-pressure gas. The device body 1 of this application has an overall cylindrical shape. The electromagnetic pulse valve 2 is installed at the upper end of the device body 1. The interior of the cylindrical device body 1 is provided with a channel for installing the electromagnetic pulse valve 2 and its pipeline. The air outlet 4 at the lower end of the device body 1 is connected to the air outlet of the electromagnetic pulse valve 2, and the air source connector 3 on one side of the device body 1 is connected to the air inlet of the electromagnetic pulse valve 2.

[0019] The dust removal device of this application can introduce compressed air into the device body 1 through the air source connector 3. Under the control of the electromagnetic pulse valve 2 at the top of the device body 1, the compressed air can intermittently generate instantaneous high-speed, high-pressure compressed air, which is sprayed radially from the gas nozzle 5 to the root of the filter bag. This causes repeated expansion and contraction changes at the root of the filter bag, thereby promoting the removal of the accumulated dust and ash adhering to the root of the filter bag, so that the filter bag and frame can be easily pulled out from the dust collector tube sheet, and the filter bag replacement operation can be completed quickly. The dust removal device of this application can also be used to clean the root of the dust collector filter bag at irregular intervals, so that the filter bag can restore the overall filtration effect of the filter bag during use.

[0020] Furthermore, such as Figure 2 As shown, the air source connector 3 is a quick-connect type air source connector 3.

[0021] In the above embodiments, the quick-connect gas source connector 3 is a standard part. After being installed on the device body 1 of this application, it will be very convenient to disassemble and assemble the gas transmission pipeline.

[0022] Furthermore, the air source connector 3 is connected to the air bag at the top of the bag filter via a flexible rubber hose.

[0023] In the above embodiments, an air tank is usually installed at the top of the bag filter, which mainly provides compressed air for the existing bag cleaning equipment. The air source connector 3 of this application can be connected to the existing air supply equipment - air tank - on the bag filter through a flexible rubber hose to provide compressed air to the dust cleaning device of this application. As for the length of the flexible rubber hose, the user can flexibly adjust it according to the size of the dust collector bags in actual production.

[0024] Furthermore, the diameter of the device body 1 is larger than the diameter of the bag opening, while the diameters of the gas nozzle 5 and the gas outlet 4 are smaller than the diameter of the bag opening.

[0025] In the above embodiments, the diameters of the gas nozzle 5 and the outlet port 4 are both smaller than the diameter of the bag opening, which facilitates the insertion of the gas nozzle 5 and the outlet port 4 into the base of the bag. The diameter of the device body 1 is larger than the diameter of the bag opening, so that when the gas nozzle 5 is inserted into the base of the bag, the device body 1 can achieve a positioning effect, allowing the gas nozzle 5 to be quickly inserted into place. At the same time, the lower end of the device body 1 can cover the upper port of the bag to provide a sealing effect.

[0026] Furthermore, such as Figure 1 and Figure 2 As shown, a hand handle 6 is fixedly welded to one of the opposite sides of the upper end of the device body 1.

[0027] In the above embodiments, the hand handle 6 provided on the device body 1 is used by the worker to operate the device by hand. When it is necessary to insert its air outlet (gas nozzle 5) into the cloth bag, the worker can press the entire device tightly at the opening of the cloth bag by holding the handle 6 to prevent the device from rebounding due to the impact of the high-pressure airflow.

[0028] Furthermore, such as Figure 1 As shown, the gas nozzle 5 is connected to the gas outlet 4 by a threaded connection, and an O-ring rubber gasket 7 for sealing is provided at the connection between the gas nozzle 5 and the gas outlet 4.

[0029] In the above embodiments, the gas nozzle 5 and the gas outlet 4 of this application are connected by a threaded connection. In this way, the gas nozzle 5 and the gas outlet 4 can be quickly disassembled and assembled as needed during use. The "O"-shaped rubber gasket 7 added at the connection area between the gas nozzle 5 and the gas outlet can improve the sealing performance after they are connected.

[0030] Furthermore, the gas nozzle 5 is conical in shape, smaller at the bottom and larger at the top; the interior of the gas nozzle 5 near its outlet is also conical, but its shape is larger at the bottom and smaller at the top.

[0031] In the above embodiments, the gas nozzle 5 of this application is configured in the manner described above, so that the ejected airflow is radial at the root of the bag, thereby better acting on the inner surface of the bag located to the side of the gas nozzle 5. In reality, nozzles that can achieve the radial ejection effect of the medium are existing technologies, and the specific structural details of such nozzles will not be described in detail here.

[0032] Furthermore, the electromagnetic pulse valve 2 is a right-angle electromagnetic pulse valve 2.

[0033] In the above embodiments, the electromagnetic pulse valve 2 of this application is preferably a right-angle electromagnetic pulse valve 2, which can not only meet the specific structural requirements of the dust removal device of this application, but also generate instantaneous high-speed and high-pressure airflow during use.

[0034] To improve the safety of the dust removal device in this application during use, a pressure gauge 9 can be installed on the device body 1 to detect the real-time internal pressure of the device during use.

[0035] The implementation principle of this embodiment is as follows: When using the dust removal device, one end of a flexible rubber hose connects the air source plug on the device body 1 to the air tank at the top of the dust collector. The worker holds the handles 6 with both hands and inserts the gas nozzle 5, located at the lower end of the device body 1, into the filter bag. To prevent airflow impact and rebound, the worker needs to press the entire device firmly against the filter bag opening using the handles 6. The electromagnetic pulse valve 2 in this application is a right-angle electromagnetic pulse valve 2, whose terminals are connected to the plant's power supply equipment via cable 8. After the electromagnetic pulse valve 2 is activated, it can generate a high-speed, high-pressure airflow inside the filter bag. The gas nozzle 5 allows the radial airflow to act on the root area of ​​the filter bag, causing the filter bag to repeatedly expand and contract, thereby promoting the removal of accumulated dust and ash from the root of the filter bag. This facilitates easy removal of the filter bag and frame during subsequent filter bag replacement, achieving a rapid filter bag replacement effect. In addition, this technology can also be used for periodic dust removal of the filter bag root to restore the overall filtration effect of the filter bag. The dust removal device of this application is a handheld operating tool that is not only simple in structure, easy to carry and move, and convenient to operate, but also has a large impact force on the cloth bag during use, has an obvious dust removal effect, and does not damage the cloth bag during dust removal.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
