Description

Technical Field

[0001] The present invention belongs to the technical field of bag dust removal, and specifically relates to a bag dust removal filter bag that is convenient for installation. Background Art

[0002] Bag dust collectors are suitable for capturing fine, dry, and non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, and the fibrous fabric is used to filter the dust-containing gas. When the dust-containing gas enters the bag dust collector, the dust with large particles and high specific gravity falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, and the gas is purified.

[0003] Most of the existing bag dust collector filter bags are sewn into a cylindrical shape, and a coil spring bracket is sewn inside the top opening to ensure that the filter bag can be stably placed in the slot hole, and then the skeleton is inserted into the filter bag to keep it in a fixed shape. However, when replacing and installing the filter bag, the used filter bag needs to be removed. During this period, the following problems exist. Since the filter bag is squeezed by the air flow for a long time, most of its surface will have depressions at the gaps of the skeleton under the support of the skeleton. When installing and replacing the filter bag and removing the skeleton, the depression will affect and block the skeleton, making it difficult to remove the skeleton. Therefore, it is necessary to develop a new type of bag dust collector filter bag that is convenient for installation and replacement. Summary of the Invention

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] As Figures 1 to 6 shown, the present invention provides a bag-type dust removal filter bag that is convenient for installation, including a filter bag body 1. A skeleton component 2 is arranged inside the filter bag body 1, and an attached support member is arranged inside the filter bag body 1 and the skeleton component 2;

[0030] The skeleton component 2 includes a bottom support plate 21 movably sleeved inside the filter bag body 1. A plurality of support rods 22 evenly distributed are fixedly connected to the top of the bottom support plate 21. A waist support ring 23 is arranged above the bottom support plate 21. The outer side of the waist support ring 23 is fixedly connected to one side of the surfaces of the plurality of support rods 22 close to the axis of the filter bag body 1. A rolling sleeve 24 is movably sleeved outside the support rods 22 and is located at the top of the bottom support plate 21 and the waist support ring 23. The rolling sleeve 24 rolls and fits on the inner wall of the filter bag body 1; due to the arrangement of the skeleton component 2, it can be hung and supported inside the filter bag body 1 in cooperation with the filter bag body 1 and the support plate 3, which can not only support the filter bag body 1, but also facilitate its removal; furthermore, due to the arrangement of the rolling sleeve 24, rotating the support plate 3 can make the rolling sleeve 24 roll and press the inner wall of the filter bag body 1, so as to eliminate the depression on the inner wall of the filter bag body 1, thereby achieving the effect of facilitating disassembly and replacement for installing a new filter bag.

[0031] As Figure 2 shown, a first spring ring 4 is sleeved outside the filter bag body 1, and the first spring ring 4 is sutured to the upper end of the filter bag body 1; due to the arrangement of the first spring ring 4, it can not only improve the rigidity of the upper end of the filter bag body 1, so that the end of the filter bag body 1 can be pressed and installed inside the slot hole by the support plate 3, but also facilitate the staff to pull out the filter bag body 1 from the slot hole through the first spring ring 4.

[0032] As Figure 2 shown, the upper ends of the plurality of support rods 22 extend above the filter bag body 1 and are fixedly connected to a support plate 3, and the support plate 3 is pressed and installed on the top of the filter bag body 1.

[0033] As Figure 2As shown, the length dimension of the skeleton component 2 is smaller than the depth dimension of the filter bag body 1. Inside the filter bag body 1, there is a dust collection bag 5 fixedly connected to the bottom of the bottom support plate 21. At the upper end of the side of the dust collection bag 5, there are several air permeable windows 6 opened. Outside the dust collection bag 5, there is a second spring ring 7 fixedly sleeved at the bottom of the air permeable windows 6. Due to the setting of the dust collection bag 5, with the cooperation of the bottom support plate 21, the dust falling inside the filter bag body 1 can be collected in the dust collection bag 5, which can avoid the blockage of the inner wall of the filter bag body 1 and affect the filtering effect of the filter bag body 1, thereby achieving the effect of extending the service life of the filter bag body 1.

[0034] As Figure 4 shown, the dust collection bag 5 is an inverted frustum structure. The inner diameter dimension of the upper end of the dust collection bag 5 is larger than the inner diameter dimension of the bottom support plate 21, and the outer diameter dimension of the upper end of the dust collection bag 5 is smaller than the outer diameter dimension of the bottom support plate 21.

[0035] As Figure 2 shown, the inside of the dust collection bag 5 communicates with the filter bag body 1 through the air permeable windows 6. The inner diameter dimension of the inner cavity of the dust collection bag 5 at the bottom edge of the air permeable windows 6 is larger than the inner diameter dimension of the bottom support plate 21. Due to the setting of the air permeable windows 6, it will neither affect the dust inside the filter bag body 1 from falling into the dust collection bag 5, nor affect the filtering and ventilation function of the part below the bottom support plate 21 of the filter bag body 1.

[0036] As Figure 2 shown, the attached support member includes an inner support plate 9 movably sleeved inside the filter bag body 1 and below the dust collection bag 5. At the top of the inner support plate 9, there is a disassembly and positioning rod 10 fixedly connected. The upper end of the disassembly and positioning rod 10 penetrates into the inside of the dust collection bag 5. Due to the setting of the attached support member, under its own weight, the inner support plate 9 can continuously press down the filter bag body 1. Furthermore, with the cooperation of the skeleton component 2 and the first spring ring 4, the filter bag body 1 can be supported in a cylindrical shape. The setting of the disassembly and positioning rod 10 can limit the movement of the inner support plate 9 with the cooperation of the dust collection bag 5 to ensure that it can continuously and stably support the bottom of the filter bag body 1.

[0037] As Figure 2 shown, there are several ash scraping components 8 arranged on the top of the bottom support plate 21. The upper ends of the ash scraping components 8 are connected to the support plate 3, and the outer sides of the ash scraping components 8 are attached to the inner wall of the filter bag body 1.

[0038] As Figure 3 and Figure 6As shown, the ash scraping component 8 includes an ash scraping plate 81 disposed between the bottom support plate 21 and the supporting plate 3. A positioning shaft 82 is movably sleeved inside the ash scraping plate 81. A connection cavity 83 is formed on the side surface of the positioning shaft 82. A clockwork spring 84 is disposed inside the connection cavity 83. Both ends of the clockwork spring 84 are fixedly connected to the inner wall of the ash scraping plate 81 and the connection cavity 83 respectively. Due to the arrangement of the ash scraping component 8, under the elastic force of the clockwork spring 84, the ash scraping plate 81 is always in close contact with the inner wall of the filter bag body 1. Further, driven by the framework component 2, the tip of the ash scraping plate 81 can move along the surface of the filter bag body 1, thereby achieving the effect of scraping the dust on the inner wall of the filter bag body 1.

[0039] As Figure 6 shown, the end of the side surface of the ash scraping plate 81 is a tip, and the tip is in close contact with the inner wall of the filter bag body 1. Both ends of the positioning shaft 82 penetrate through the ash scraping plate 81 and are fixedly connected to the bottom support plate 21 and the supporting plate 3.

[0040] The working principle and usage process of the present invention:

[0041] During installation, first, the lower end of the filter bag body 1 is placed into the flower plate slot hole from top to bottom through the first spring ring 4 and gradually moved downward until the upper end of the filter bag body 1 fits against the top of the slot hole under the cooperation of the first spring ring 4. Then, the attached support member is inserted into the filter bag body 1 from top to bottom. Finally, the framework component 2 is inserted into the filter bag body 1 from top to bottom, and at the same time, the disassembly positioning rod 10 penetrates through the ash receiving bag 5. Finally, the supporting plate 3 presses the upper end of the filter bag body 1 and the first spring ring 4.

[0042] During disassembly, first, the framework component 2 is rotated back and forth to make the roller 24 roll along the inner wall of the filter bag body 1 until the surface of the filter bag body 1 is flat and sunken. At this time, the framework component 2 is moved upward to be pulled out from the filter bag body 1. Finally, the filter bag body 1 is pulled out.

[0043] During daily maintenance, the supporting plate 3 is rotated back and forth to drive the roller 24 to roll along the inner wall of the filter bag body 1, reducing the degree of surface depression of the filter bag body 1. At the same time, several ash scraping components 8 can be driven to move along the inner wall of the filter bag body 1. Further, due to the restriction of the positioning shaft 82, the end of the moving ash scraping plate 81 can scrape the dust on the inner wall of the filter bag body 1 under the elastic force of the clockwork spring 84 and fall into the ash receiving bag 5 under the action of gravity.

[0044] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
