Description

Technical Field

[0001] This utility model relates to the field of dust collector filter bag technology, specifically a dust collector filter bag that can be installed quickly. Background Technology

[0002] Dust collector filter bags are a type of high-efficiency dust collection filter material. They have good air permeability, high dust collection efficiency, and certain resistance to acids, alkalis, and heat. Dust collector filter bags are the heart of baghouse dust collectors during operation. Typically, cylindrical dust collector filter bags are vertically suspended on the tube sheet of the dust collector. Dust-laden gas enters the dust collector through the inlet and passes through the guide plate in the ash hopper, where some of the large dust particles in the gas are separated by inertial force and fall directly into the ash hopper.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN215232822U) discloses a dust collector filter bag capable of rapid installation and disassembly. The bag includes a filter bag body, an annular elastic sleeve fitted over the outside of the filter bag body, a camshaft, and a rotating rod. The elastic sleeve has a through tension groove along its axial direction on its side, and a first and second locking groove are formed on its top surface opposite the tension groove. The camshaft is rotatably disposed within the tension groove, with its side contacting both sides of the groove to change its width. The rotating rod is rotatably connected to the top of the camshaft, driving its rotation and capable of flipping relative to the camshaft axis to engage in the first or second locking groove. The elastic sleeve of this utility model expands in outer diameter or elastically retracts to its original size as the camshaft rotates within the tension groove. During use, simply rotating the rotating rod controls the tightening or loosening of the elastic sleeve, enabling rapid installation and disassembly of the dust collector filter bag in dust collection equipment.

[0004] Although the aforementioned patent achieves installation and disassembly by expanding or contracting the outer diameter of the elastic sleeve, the slots on the elastic sleeve create a gap when the dust collector filter bag is inserted into the dust collector tube sheet, which can easily lead to dust leakage and compromise the sealing of the installation. Furthermore, while traditional filter bags achieve a sealed installation, they use an elastic plate built into the filter bag opening to abut against the inner wall of the dust collector tube sheet mounting hole. Although this ensures a seal, the built-in elastic plate makes the locking and unlocking operation somewhat inconvenient, and the elastic plate may break due to improper force during locking, posing a certain operational risk.

[0005] Therefore, this utility model provides a quick-installing dust collector filter bag to solve the above problems. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1-5 As shown, this utility model provides a quick-installation dust collector filter bag, including a bag body 1, a lower support plate 11 fixedly connected to the top of the bag body 1, an upper support plate 13 fixedly connected to the top of the lower support plate 11, and a rubber sealing ring 12 fixedly connected to the lower surface of the lower support plate 11; a locking assembly 3, which includes a drive ring 31, and the drive ring 31 is rotatably connected to the lower support plate 11 and the upper support plate 13. A gear ring 32 is fixedly connected to the inner wall of the drive ring 31, and a gear 33 meshes inside the gear ring 32. A main shaft 34 is fixedly connected to the center of the gear 33, and the main shaft 34 is rotatably connected to the lower support plate 11. A clamping plate 35 is fixedly connected to the bottom of the main shaft 34; a pressure plate 2, and a cage frame 21 and a pin 22 are fixedly connected to the bottom of the pressure plate 2. 1. Insert the bag body 1 into the interior. When installing and positioning the bag body 1, first insert the bag body 1 through the mounting hole below the dust collector tube sheet, so that the rubber sealing ring 12 abuts against the upper surface of the dust collector tube sheet. By pressing down the entire locking assembly 3, the rubber sealing ring 12 is compressed and contracted. At this time, the locking plate 35 can descend to the lower surface of the dust collector tube sheet. Further, by rotating the drive ring 31, the main shaft 34 and the locking plate 35 can be rotated through the meshing transmission of the gear ring 32 and the gear 33. After the locking plate 35 rotates to the lower surface of the dust collector tube sheet, release the pressure on the locking assembly 3. At this time, the rubber sealing ring 12 returns to its elasticity, so that the locking plate 35 abuts against the lower surface of the dust collector tube sheet. The compressed state of the rubber sealing ring 12 ensures the sealing performance of its installation.

[0031] Furthermore, the outer diameter of the rubber sealing ring 12 is equal to the outer diameter of the lower support plate 11, and the inner diameter of the rubber sealing ring 12 is greater than the inner diameter of the lower support plate 11. The toothed ring 32 and the gear 33 are located between the lower support plate 11 and the upper support plate 13. The setting of the rubber sealing ring 12 can improve the sealing performance of the device installation and avoid dust leakage during installation.

[0032] Furthermore, the drive ring 31 has an L-shaped cross-section, and a rotating ring is provided between the drive ring 31 and the lower support plate 11 and the upper support plate 13. The toothed ring 32 is fixedly connected to the inner wall of the rotating ring. In order to ensure the smooth rotation of the drive ring 31 under pressure, a thrust bearing can be installed between the contact surfaces of the drive ring 31 and the upper support plate 13 or the drive ring 31 and the lower support plate 11 to ensure the smooth rotation between the drive ring 31 and the lower support plate 11 and the upper support plate 13 under pressure, and to avoid mutual squeezing and friction between the two, which would affect the rotation of the drive ring 31.

[0033] Furthermore, there are eight sets of gears 33, main shafts 34 and clamping plates 35 evenly distributed around the circumference. The main shafts 34 are distributed between the inner diameter of the lower support plate 11 and the inner diameter of the rubber sealing ring 12. The outer wall of the main shaft 34 is rotatably connected to the lower support plate 11 through ball bearings. The distribution of the clamping plates 35 in multiple positions improves the stability of the dust collector tube sheet engagement and provides uniform pressure to the rubber sealing ring 12, ensuring the uniformity of the seal of the rubber sealing ring 12.

[0034] Furthermore, the drive ring 31 is provided with positioning holes, and the upper support plate 13 is provided with adjustment holes on both sides corresponding to the main shaft 34. A pin 22 is inserted between the positioning hole and the corresponding adjustment hole. The insertion and positioning of the drive ring 31 in the locked state is achieved by the insertion of the pin 22, which can ensure the stability of the locked state and prevent the drive ring 31 from rotating due to external forces such as vibration, which would cause it to fall off.

[0035] Furthermore, the dust collector tube sheet is sandwiched between the clamping plate 35 and the rubber sealing ring 12, and the thickness of the dust collector tube sheet is not less than the distance between the rubber sealing ring 12 and the clamping plate 35 under normal conditions. This allows the clamping plate 35 to be clamped under the dust collector tube sheet when the rubber sealing ring 12 is under pressure, thereby improving its installation sealing performance.

[0036] Working principle: During installation and use, first, insert the bag body 1 through the bottom of the dust collector tube sheet, ensuring that the rubber sealing ring 12 is in contact with the upper surface of the dust collector tube sheet. Then, press down on the drive ring 31, causing the pressure plate 2 to move downwards under the compressed state of the rubber sealing ring 12. At this time, rotate the drive ring 31, and drive the main shaft 34 and the clamping plate 35 to rotate through the meshing transmission of the gear ring 32 and gear 33. After the clamping plate 35 rotates to the bottom of the dust collector tube sheet, release the pressure on the drive ring 31. Under the elastic recovery of the rubber sealing ring 12, the clamping plate 35 engages and abuts against the bottom of the dust collector tube sheet. The clamping of the clamping plate 35 and the compressed rubber sealing ring 12 ensures the stability and sealing of the device installation. Finally, insert the cage frame 21 into the inside of the bag body 1, and insert it between the upper support plate 13 and the drive ring 31 through the pin 22, completing the auxiliary support of the bag body 1 while realizing the insertion and positioning of the drive ring 31.

[0037] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
