Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a highly waterproof industrial filtering bag. Background Art

[0002] Filter bag is a common filtering equipment, widely used in the filtration and purification of gas or liquid. Its working principle is to filter the particles or droplets in the gas or liquid through the filter material to achieve the purpose of purification. The material of the filter bag is usually made of fiber material, which has a certain porosity and pore size inside. When the gas passes through the filter bag, the particles or droplets will be captured by these pores and pores, and the clean gas can be discharged through the filter bag. The use scenarios of filter bags are very wide, so it is necessary to optimize the installation of filter bags.

[0003] For example, a water-removing and corrosion-resistant bag filter is disclosed in a Chinese utility model patent with announcement number CN219744277U. In the above-mentioned prior art, although water vapor will condense on the air inlet surface of the filter cotton to form droplets when the equipment is running, and then drip along the inner wall of the filter bag to the bottom of the filter for waterproofing, the filter bag will gradually be penetrated by water vapor during long-term use, causing the filter holes of the filter bag to be blocked, resulting in reduced filtering effect and poor air circulation. Therefore, the filter bag needs to be replaced and maintained at regular intervals, and the filter bag is sealed and installed on the mounting plate. It is difficult to seal and install a new filter bag on the mounting plate after removing the filter bag. Therefore, each replacement requires replacing the mounting plate together with the filter bag, which is a great waste of resources. Therefore, it is necessary to design a filtering device that can remove the filter bag that needs to be replaced separately and seal and install the new filter bag when the filter bag needs to be replaced after long-term waterproof filtration. Utility Model Content

[0004] In order to solve the technical problem that each time the filter bag is replaced, the mounting plate must be replaced together with the filter bag, which is a great waste of resources, the utility model provides a highly waterproof industrial filter bag.

[0005] The utility model is implemented by the following technical scheme: a highly waterproof industrial filter bag, including a mounting plate, one side of the mounting plate is provided with a plurality of filter ports for filtering, one side of each of the filter ports is provided with a filter component for filtering water vapor in the air and preventing water from flowing, one side of each of the filter components is provided with a replacement component for facilitating replacement of the filter component, and both sides of each of the filter components are provided with fixing components for facilitating installation and fixing after the filter component is replaced.

[0006] Through the above technical solution, when the filter bag has been waterproofing for a long time, the waterproof filter bag can be replaced using the replacement component and the fixing component.

[0007] As a further improvement of the above solution, the filter assembly includes a water vapor filter bag arranged at one side of the filter port for filtering water vapor in the air and a waterproof filter bag arranged inside the water vapor filter bag for blocking water flow.

[0008] Through the above technical solution, the water vapor filter bag blocks and filters the moisture in the air, and the waterproof filter bag directly blocks and filters the water droplets or small water droplets.

[0009] As a further improvement of the above scheme, a sealing bag is fixedly provided on the bottom outer surface of the water vapor filter bag to prevent water droplets from penetrating, and a plurality of connecting belts are provided inside the waterproof filter bag, and both sides of the plurality of connecting belts are fixedly installed on both sides of the inside of the waterproof filter bag.

[0010] Through the above technical solution, when the filter bag has been waterproofed for a long time, the accumulated water droplets will penetrate the filter bag and be collected by the sealing bag.

[0011] As a further improvement of the above scheme, the replacement component includes a first fixing plate fixedly installed at the opening of the water vapor filter bag and a second fixing plate fixedly installed at the opening of the waterproof filter bag, the first fixing plate is provided with a fixing groove adapted to the second fixing plate, one side of the second fixing plate is provided with a flow port adapted to the filter port, the outer surface of the first fixing plate is fixedly sleeved with a sealing strip for sealing the gap between the first fixing plate and the installation groove, and one side of the installation plate is provided with an installation groove adapted to the sealing strip.

[0012] Through the above technical solution, the waterproof filter bag cooperates with the second fixing plate and is installed inside the water vapor filter bag.

[0013] As a further improvement of the above scheme, the fixing assembly includes two limit plates arranged on one side of the water vapor filter bag and having sliding grooves, and a limit block slidably arranged inside each sliding groove, and one side of each limit block extends through the sliding groove to one side of the first fixing plate and fits with the first fixing plate.

[0014] Through the above technical solution, after the filter bag is replaced, the sliding limit block can fix the first fixing plate to prevent the filter bag from loosening.

[0015] As a further improvement of the above solution, a push plate for moving the two limit blocks is fixedly installed on one side of the two limit blocks, a push spring is fixedly installed on one side of the push plate, and a baffle fixedly installed on one end of the push spring is fixedly installed on the mounting plate.

[0016] Through the above technical solution, the push spring can keep the push plate stationary, preventing the push plate from moving and causing the two limit blocks to move, causing the filter bag to loosen.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model provides a filter assembly, a replacement assembly and a fixing assembly, so that when the filter assembly needs to be replaced after long-term waterproof filtration, the fixing effect of the fixing assembly on the replacement assembly is released, and the filter assembly and the replacement assembly are removed from the mounting plate. If it is necessary to replace the water vapor filter bag or the waterproof filter bag separately, the two filter bags are disassembled and replaced and assembled using the replacement assembly, and then they are reinstalled back on the mounting plate and the replacement assembly is fixed using the fixing assembly to complete the replacement. After long-term waterproof filtration of multiple filter assemblies on the mounting plate, a certain filter assembly can be quickly replaced separately, avoiding the waste caused by replacing the entire mounting plate and multiple filter assemblies together.

[0026] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0027] Please combine Figure 1-Figure 5A highly waterproof industrial filter bag of the present embodiment includes a mounting plate 1, a plurality of filter ports for filtering are provided on one side of the mounting plate 1, a filter component for filtering water vapor in the air and preventing water from flowing is provided on one side of each filter port, a replacement component for facilitating replacement of the filter component is provided on one side of each filter component, and fixing components for facilitating installation and fixing after the filter component is replaced are provided on both sides of each filter component.

[0028] Combination Figure 5 The filter assembly includes a water vapor filter bag 201 arranged at one side of the filter port for filtering water vapor in the air and a waterproof filter bag 202 arranged inside the water vapor filter bag 201 for blocking water flow. A sealing bag 5 is fixedly sleeved on the bottom outer surface of the water vapor filter bag 201 to prevent water droplets from penetrating. A plurality of connecting belts 6 are arranged inside the waterproof filter bag 202. Both sides of the plurality of connecting belts 6 are fixedly installed on both sides of the waterproof filter bag 202. The water vapor filter bag 201 blocks and filters moisture in the air, and the waterproof filter bag 202 directly blocks and filters water droplets or large water molecules.

[0029] Combination Figure 2 and Figure 4 The replacement component includes a first fixing plate 301 fixedly installed at the opening of the water vapor filter bag 201 and a second fixing plate 302 fixedly installed at the opening of the waterproof filter bag 202. The first fixing plate 301 is provided with a fixing groove adapted to the second fixing plate 302, and one side of the second fixing plate 302 is provided with a flow port adapted to the filter port. The outer surface of the first fixing plate 301 is fixedly sleeved with a sealing strip 7 for sealing the gap between the first fixing plate 301 and the installation groove, and one side of the installation plate 1 is provided with an installation groove adapted to the sealing strip 7. The waterproof filter bag 202 cooperates with the second fixing plate 302 and is installed inside the water vapor filter bag 201.

[0030] Combination Figure 2-Figure 4 The fixing assembly includes two limit plates 401 arranged on one side of the water vapor filter bag 201 and having sliding grooves, and a limit block 402 slidably arranged inside each sliding groove, one side of each limit block 402 extends through the sliding groove to one side of the first fixed plate 301 and fits with the first fixed plate 301, one side of the two limit blocks 402 is fixedly installed with a pushing plate 8 for moving the two limit blocks 402, one side of the pushing plate 8 is fixedly installed with a pushing spring 9, and one end of the pushing spring 9 is fixedly installed with a baffle 10 fixedly installed with the mounting plate 1, after the filter bag is replaced, the sliding limit block 402 can fix the first fixed plate 301 to prevent the filter bag from loosening.

[0031] The implementation principle of a highly waterproof industrial filter bag in the embodiment of the present application is as follows: when waterproof filtering is performed, the humidity in the air is high, and the waterproof filter bag 202 will block the larger water molecules in the air in advance to avoid only one water vapor filter bag 201 filtering and affecting the filtering effect. The smaller water molecules in the air can pass through the waterproof filter bag 202, but most of the smaller water molecules will be blocked and filtered by the water vapor filter bag 201, so that the air with high humidity can only carry a small amount of water vapor through the water vapor filter bag 201 to maintain normal humidity in the air. After the waterproof filter bag 202 and the water vapor filter bag 201 have been working for a long time in waterproof filtering, the filter bag itself will need to be replaced. At this time, the sliding push plate 8 is used to move the four limit blocks 402 on both sides of the water vapor filter bag 201. The fixing effect of the first fixing plate 301 is lost, so that the first fixing plate 301 can be removed from the fixing groove of the mounting plate 1, and the waterproof filter bag 202 or the water vapor filter bag 201 can be replaced separately, or they can be replaced together. For replacement separately, the second fixing plate 302 needs to be disassembled from the first fixing plate 301, so that the water vapor filter bag 201 and the waterproof filter bag 202 can be separated, and the new filter bag can be reinstalled, and then the first fixing plate 301 is pressed into the fixing groove with the sealing strip 7, and the pushing spring 9 is released, and the pushing plate 8 will push the limit block 402 again to fix the first fixing plate 301, thereby completing the replacement of a single filter bag and avoiding the waste caused by the need to disassemble and replace the entire device because of the need to replace one filter bag.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
