Description

Technical Field

[0001] The present invention relates to the technical field of dust removal filter bags, and in particular to a dust removal filter bag which is easy to install and maintain based on digital management. Background Art

[0002] The dust bag is the heart of a bag filter, often referred to as a filter bag, dust filter bag, dust collection bag, dust collection bag, dust collector bag, or dust collector bag. The dust bag is a critical component of bag filter operation. Typically, cylindrical filter bags are suspended vertically within the dust collector. A dust collector, or dust removal equipment, is a device that separates dust from flue gas. A bag filter, also known as a filter dust collector, is a dry, high-efficiency dust collector that utilizes a woven fiber bag filter element to capture solid particles in dust-laden gas. Its function is that dust particles, as they pass around the filter cloth fibers, collide with them due to inertial forces and are intercepted. In pulse and airbox pulse dust collectors, dust adheres to the outer surface of the filter bag. As dust-laden gas passes through the dust collector, it is trapped on the outer surface of the filter bag, while clean gas passes through the filter media and enters the bag interior. The cage within the filter bag supports the bag, preventing it from collapsing and facilitating the removal and redistribution of dust cake.

[0003] In the existing technology, multiple groups of dust filter bags need to be installed on the mounting plate of the dust removal equipment. However, the bottom structure of the current dust filter bag is fixed by connecting the mounting plate with a flange at the bottom of the cage, and then the filter bag is combined with the cage through a clamp on the surface, which makes it inconvenient to dismantle and maintain. It cannot adapt to the existing digital management and disassembly, and it takes a long time to dismantle. In addition, the centralized detection of the flue gas sensor cannot know the status of each filter bag, so it is impossible to perform accurate digital management and accurate dismantling and maintenance, which reduces maintenance efficiency.

[0023] See also Figure 1 , Figure 1 It is a structural schematic diagram of the present invention.

[0024] The dust filter bag which is easy to install and maintain based on digital management includes a mounting base 1, a dust filter bag 2 mounted on the top of the mounting base 1 and a controller 3 fixedly mounted on one side of the mounting base 1. An elastic snap-fit component 4 is fixedly mounted on the bottom of the dust filter bag 2. A mounting hole 5 located at the bottom of the dust filter bag 2 is opened on the top of the mounting base 1. Mounting grooves 6 are opened on both sides of the bottom inner wall of the bottom of the mounting hole 5. An electric quick-release mechanism 7 is arranged inside the mounting groove 6. A sealing cover 8 is detachably mounted on the top of the mounting base 1 by bolts. An electric flue gas isolation mechanism 9 located next to the dust filter bag 2 is fixedly mounted on the top of the sealing cover 8 and the bottom of the mounting base 1. A partition 10 is welded on the top of the mounting base 1. A flue gas sensor 11 located on one side of the mounting hole 5 is fixedly mounted on the top of the mounting base 1. The flue gas sensor 11 is electrically connected to the controller 3. An inspection cover 12 is welded on the top of the sealing cover 8. An inspection door 13 is movably mounted on one side of the inspection cover 12 through a hinge. The surface of the inspection door 13 is provided with a sealing ring which seals with the inspection cover 12.

[0025] See also Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , Figure 2 It is a partially cutaway perspective schematic diagram of the present invention; Figure 3 A partially half-cut exploded perspective view of the mounting base of the present invention; Figure 4 An exploded perspective view of the dust filter bag of the present invention; Figure 5 is a schematic perspective cross-sectional view of a partial substrate of the present invention; Figure 6 for Figure 5 A magnified view of center.

[0026] The elastic clamping assembly 4 includes an annular cone 401, a clamping seat 402 is fixedly installed at the bottom of the annular cone 401, an elastic cylinder 403 is slidably installed on the top of the inner wall of the mounting hole 5, and an annular cone surface is provided on the top of the elastic cylinder 403 to cooperate with the annular cone 401. A spring 404 is fixedly installed at the bottom of the elastic cylinder 403, and the other end of the spring 404 is fixedly installed on the bottom of the inner wall of the mounting hole 5. After the top surface of the annular cone 401 and the elastic cylinder 403 are pressed together, the sealing area can be increased. At the same time, the spring 404 at the bottom can use the elastic force to make the elastic cylinder 403 and the annular cone 401 tightly pressed against each other for sealing, and eliminate the sealing gap through the elastic force.

[0027] The electric quick-release mechanism 7 includes an electromagnetic push rod 701, and a pin 702 is fixedly installed at the output end of the electromagnetic push rod 701. The pin 702 is plugged into the clamping seat 402. A protective plate 703 is provided at the bottom of the inner wall of the installation groove 6. The four corners of the bottom of the protective plate 703 are screwed to the installation groove 6 by bolts. The electromagnetic push rod 701 is electrically connected to the controller 3 through a wire. After the electromagnetic push rod 701 is closed, the pin 702 can be popped out through the internal elastic structure to plug into the clamping seat 402 to complete the plug-in limit fixation. The protective plate 703 can prevent particles in the flue gas from colliding and damaging the electromagnetic push rod 701. After being electrically connected to the controller 3, it can be quickly and conveniently disassembled through signals, and maintenance personnel do not need to enter the dust removal equipment to replace it.

[0028] The electric flue gas isolation mechanism 9 includes a servo 901, which is respectively embedded and fixed on the bottom of the mounting base plate 1 and the top of the sealing cover 8. An isolation plate 902 is fixedly installed at the output end of the servo 901, and a frustum sealing gasket 903 is fixedly installed on the side of the isolation plate 902 close to the dust filter bag 2. A smoke exhaust replacement hole 904 used in conjunction with the isolation plate 902 is opened on the top of the sealing cover 8. The servo 901 can control the isolation plate 902 to rotate and open and close, so that the isolation plate 902 cooperates to seal and open the smoke exhaust replacement hole 904 and the mounting hole 5. At the same time, the frustum sealing gasket 903 can be adapted to seal the inner wall of the smoke exhaust replacement hole 904 and the mounting hole 5 to prevent smoke leakage.

[0029] The dust filter bag 2 includes a filter cage 14 and a cloth bag 15 mounted on the surface of the filter cage 14. An adsorption block 16 is fixedly embedded on the top of the inner wall of the filter cage 14. The filter cage 14 limits the expansion of the cloth bag 15 to ensure the dust removal area. At the same time, the adsorption block 16 can cooperate with maintenance personnel to quickly remove the dust filter bag 2.

[0030] The outer surface of the elastic tube 403 is coated with a sealing layer, and the surface of the elastic tube 403 is sealed with the inner wall of the installation hole 5. The top conical surface of the elastic tube 403 is sealed with the bottom of the annular conical tube 401. The sealing layer can ensure that the surface of the elastic tube 403 that moves up and down is sealed with the installation hole 5, preventing smoke leakage and improving the sealing performance of the dust filter bag after installation.

[0031] A proximity sensor 17 is fixedly embedded on the top of the mounting base plate 1. The proximity sensor 17 is located on one side of the mounting hole 5. The proximity sensor 17 is electrically connected to the controller 3 through a wire. The proximity sensor 17 is used in conjunction with the isolation plate 902. The proximity sensor 17 can detect whether the isolation plate 902 is closed each time, thereby avoiding the situation where smoke leakage is caused by the isolation plate 902 not being reset and not being noticed.

[0032] A replaceable electromagnetic suction block 18 is provided on the top of the sealing cover 8. The top of the electromagnetic suction block 18 is electrically connected to a conductive wire 19. The surface of the conductive wire 19 is wrapped with a heat insulation protective cover 20. The electromagnetic suction block 18 is used in conjunction with the adsorption block 16. The electromagnetic suction block 18 cooperates with the conductive wire 19 to control the opening and closing of the magnetic force after being connected to an external power supply. After opening the upper isolation plate 902, the magnetic force of the electromagnetic suction block 18 is turned off, and the top of the dust filter bag 2 is placed and then the electromagnetic suction block 18 is started to attract the adsorption block 16. At this time, the electric quick-release mechanism 7 is cooperated to make the dust filter bag 2 lose its clamping force, which makes it convenient for maintenance personnel to extract the dust filter bag 2 upward for replacement and maintenance.

[0033] Working principle: When performing flue gas detection, the bottom isolation plate 902 is opened by the servo 901 to facilitate the flue gas to enter the dust filter bag 2 for filtration, and the flue gas is grouped by the partition 10 to facilitate the detection of different filtration conditions. When the detection data of one group of dust filter bags 2 is abnormal, the corresponding servo 901 at the bottom can be started in time by the controller 3 to twist the isolation plate 902 to the corresponding installation hole 5 and the smoke exhaust replacement hole 904 for sealing to prevent the damaged dust filter bag 2 from continuing to filter and causing the flue gas filtration effect to deteriorate. When the maintenance personnel have time, they can open the maintenance door 13 and start the corresponding servo 901 at the top to unfold the isolation plate 902. Then the maintenance personnel control the opening and closing of the magnetic force by holding the electromagnetic suction block 18 and connecting it with the conductive wire 19 to the external power supply, turn off the magnetic force of the electromagnetic suction block 18, put it into the top of the dust filter bag 2, and then start the electromagnetic suction block 18 and the suction The auxiliary block 16 is attracted, and at this time the electromagnetic push rod 701 is started to move the pin 702 to the side away from the clamping seat 402, so that the clamping seat 402 loses its clamping force. After the dust filter bag 2 loses its clamping force, it is convenient for maintenance personnel to extract the dust filter bag 2 upward for replacement and maintenance, thereby improving the efficiency of rapid maintenance. After the electromagnetic suction block 18 is connected to the external power supply in conjunction with the conductive wire 19, the magnetic force is controlled to put in a new dust filter bag 2. After closing the electromagnetic push rod 701, the internal elastic structure pops out the pin 702 and plugs it into the clamping seat 402 at the bottom of the dust filter bag 2 to complete the plug-in limit fixation. Then the magnetic force is disconnected and the electromagnetic suction block 18 is taken out. Subsequently, the servo 901 is started to move the top isolation plate 902 to the smoke exhaust replacement hole 904, and the closing signal is obtained through the proximity sensor 17. After confirming the closure, the maintenance personnel close the inspection door 13 to complete the inspection and replacement operation, thereby improving the replacement efficiency.
