Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of filter bags, in particular to a special filter bag for industrial gases. Background Art
[0002] As a key component in a dust collector, the filter bag plays a crucial role. The filter bag can effectively capture dust and pollutants in the gas, filter particulate matter or droplets in the gas through the filter material, so as to achieve the purpose of purification. In the production processes of different industries, selecting a suitable filter bag can improve product quality.
[0003] In the prior art, the patent application number "CN202321132825.X" is disclosed, which is a high-efficiency filter bag for a gas purifier. It includes a mounting plate, a connecting plate is installed at the bottom end of the mounting plate, a filter bag is installed at the bottom end of the connecting plate, and a filter screen is installed inside the mounting plate. The filter screen first filters out larger particles and corrosives in the gas, reduces the blockage of the filter bag and the attachment of corrosives, prolongs the service life of the device, and by adjusting the height of the filter bag, it is applicable to different gas purifiers, increasing the compatibility of the device.
[0004] This filter bag can only adjust the height of the filter bag. In actual use, the filter bag itself is relatively soft, so the inside of the filter bag cannot be supported and unfolded, resulting in the filter bag being prone to wrinkles and unable to effectively carry out the filtering work, thus affecting the filtering effect of the waterproof environmental protection filter bag and being inconvenient to use.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0026] As Figures 1 to 5 shown, a special filter bag for industrial gases includes a filter bag body 1. A first connecting steel ring 66 is fixedly provided on the upper side of the filter bag body 1. A first mounting ring 2 is slidably connected inside the filter bag body 1. A vertically arranged vertical plate 9 is installed on the lower side of the first mounting ring 2. A second mounting ring 10 for telescopic adjustment is slidably connected to the lower side of the vertical plate 9. An array of second springs 11 is installed between the vertical plate 9 and the second mounting ring 10;
[0027] A second connecting rigid ring 6 is fixedly provided on the lower side of the filter bag body 1, and a bottom bag 7 is fixedly connected to the lower side of the second connecting rigid ring 6. The outer surfaces of the first mounting ring 2 and the second mounting ring 10 are both slidably connected with an array of movable positioning rods 3. Through the arrangement of the movable positioning rods 3, the elastic movable positioning rods 3 can position the two mounting rings so as to support the filter bag. A first spring 4 is connected between the movable positioning rods 3 and the first mounting ring 2 and the second mounting ring 10 respectively. Rubber round pads 8 are arrayedly connected to the outer surfaces of the first mounting ring 2 and the second mounting ring 10. Through the arrangement of the rubber round pads 8, the first mounting ring 2 and the second mounting ring 10 can be squeezed and fixed at the two connecting rigid rings, so as to stably position the two mounting rings and improve the stability of supporting the filter bag.
[0028] One side of the vertical plate 9 is fixedly connected with a support plate 12, and a first soft brush 13 is installed on one side of the support plate 12.
[0029] Arc plates 14 are fixedly installed on one side of the first mounting ring 2 and the second mounting ring 10 in an array, and a second soft brush 15 is installed on one side of the arc plates 14.
[0030] The inner sides of the movable positioning rods 3 respectively penetrate through the first mounting ring 2 and the second mounting ring 10 and extend to the inside of the first mounting ring 2 and the second mounting ring 10. A fixed grip 5 for moving the movable positioning rods 3 is fixedly installed on the inner sides of the movable positioning rods 3.
[0031] Arrayed embedding grooves 111 are formed inside the first mounting ring 2 and the second mounting ring 10. The embedding grooves 111 are adapted to the movable positioning rods 3. One side of the movable positioning rods 3 is slidably clamped with the inside of the first mounting ring 2 and the second mounting ring 10 respectively through the embedding grooves 111.
[0032] Arrayed limiting grooves 222 are formed inside the first mounting ring 2 and the second mounting ring 10. The limiting grooves 222 are adapted to the rubber round pads 8. One side of the rubber round pads 8 is clamped with the inside of the first mounting ring 2 and the second mounting ring 10 respectively through the limiting grooves 222.
[0033] The working principle of a special filter bag for industrial gases provided by the utility model is as follows:
[0034] By first pulling the fixed grip 5 at the second mounting ring 10, the fixed grip 5 will drive the movable positioning rod 3 equipped with the first spring 4 to contract. Then, place the second mounting ring 10 into the interior of the filter bag body 1 until the first mounting ring 2 is mounted above the filter bag body 1. Next, pull the fixed grip 5 again to make the movable positioning rod 3 equipped with the first spring 4 at the first mounting ring 2 also contract. Then, snap the first mounting ring 2 into the interior of the filter bag body 1. Subsequently, release the fixed grip 5. In this way, the elastic movable positioning rod 3 can be snapped into the embedding grooves 111 of the first connecting rigid ring 66 and the second connecting rigid ring 6 to fix the first mounting ring 2, so that the vertical plate 9 at the first mounting ring 2 and the second mounting ring 10 can support inside the filter bag, enabling the industrial gas special filter bag to be fully unfolded for effective filtering work and improving the filtering effect on industrial gas.
[0035] By pulling upward the first mounting ring 2 equipped with the second spring 11 at the second mounting ring 10, the elastic first mounting ring 2 can be adjusted and moved upward, so that the first mounting ring 2 can be flexibly adjusted to support filter bags of different sizes and heights, improving the supporting effect on the industrial gas special filter bag. Then, pull the fixed grips 5 at the second mounting ring 10 and the first mounting ring 2 together to release the limit fixation on the first connecting rigid ring 66 and the second connecting rigid ring 6, allowing the second mounting ring 10 and the first mounting ring 2 to move upward. Subsequently, the entire mounting ring can be rotated, so that the first soft brush 13 at the support plate 12 can continuously clean the interior of the filter bag. At the same time, when the entire mounting ring is removed, it will also drive the second soft brush 15 at the arc plate 14 to clean the interior of the filter bag once to effectively clean the particulate matter and improve the cleaning efficiency of the industrial gas special filter bag.
[0036] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
