Description

Technical Field

[0001] The utility model relates to the field of filter tanks of air separation equipment, in particular to a tank for a filter device which is easy to maintain. Background Art

[0002] Air separation equipment is a gas separation equipment that liquefies, distills and finally separates air into oxygen, nitrogen and other useful gases. The SMN nitrogen membrane system is a common air separation equipment. The SMN nitrogen membrane system consists of an air compressor, a filter and an SMN membrane separation nitrogen production device. The filter is a very important processing equipment. Its main function is to filter out solid, liquid and gas impurities in the air, thereby ensuring that the generated chlorine has a higher purity. At the same time, the filter can also filter out oil droplets, moisture, particulate matter and other adhesions in the gas, thereby ensuring the cleanliness and dryness of the gas.

[0003] The filter is installed inside the filter tank. The filter tank can ensure the sealing of the entire filtering process and ensure a higher gas purification rate. Therefore, the filter tank needs to be maintained regularly. However, the size of the tank body is different for different production lines. The filter tank with a higher height is more inconvenient to maintain. You can choose to place it horizontally. However, the traditional tank body is stabilized by several supporting legs at the bottom. Therefore, the tank body is easy to roll during maintenance, which is inconvenient for staff to operate.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-4 As shown, a tank body for a filtering device that is easy to maintain includes a filter tank 1, a sealing cover 2 is installed on the top of the filter tank 1, and flanges 3 are installed at the connecting positions of the sealing cover 2 and the filter tank 1, and the flanges 3 are installed and fixed by welding. A non-circular mounting plate 4 is fixedly installed on the surface of the filter tank 1. In the present embodiment, the mounting plate 4 is set to be rectangular, and of course, a triangle or other polygon can also be set. A movable plate 5 is movably sleeved on the surface of the filter tank 1, and the movable plate 5 can extend the axial direction of the filter tank 1 to move. The movable plate 5 has the same shape and size as the mounting plate 4, and the mounting method completely overlaps in the longitudinal direction. A plurality of support rods 6 are fixedly installed on the lower surface of the movable plate 5. In the basic embodiment, the number of support rods 6 is set to four, which are respectively located at the four corners of the mounting plate 4. A through groove 7 is opened at the corresponding position of the surface of the mounting plate 4, and the support rod 6 movably passes through the through groove 7 and is supported on the ground, and a connecting component is provided between the movable plate 5 and the mounting plate 4.

[0020] During installation, the movable plate 5 is sleeved on the surface of the filter tank 1, and the mounting plate 4 is directly fixed by welding. Then the support rod 6 is passed through the inside of the through groove 7. At this time, the support rod 6 has a certain guiding effect, which can ensure that the installation position of the movable plate 5 is correct. Finally, the movable plate 5 and the mounting plate 4 are fixed by the connecting assembly to ensure that the support rod 6 is supported on the ground. At this time, it can be used normally. When it needs to be placed horizontally for maintenance, the connecting assembly is unlocked, and the movable plate 5 is moved on the surface of the filter tank 1 until it moves to the surface of the flange 3. At this time, the filter tank 1 is laid down. Since the movable plate 5 and the mounting plate 4 are in contact with the ground as flat surfaces, the filter tank 1 can be prevented from rolling, which is convenient for staff to maintain.

[0021] The connecting assembly includes a plurality of mounting holes 8. In the present embodiment, there are four mounting holes 8, which are opened on the surfaces of the support plate 9 and the movable plate 5. Bolts 10 are movably inserted inside the mounting holes 8, and nuts 11 are threadedly sleeved on the surfaces of the bolts 10. The heads of the bolts 10 abut against the surface of the movable plate 5, and the nuts 11 abut against the surface of the mounting plate 4. The position of the movable plate 5 is fixed by the cooperation of the bolts 10 and the nuts 11, and the mounting structure is simple and highly stable.

[0022] The outer diameter of the flange 3 is greater than the inner diameter of the movable plate 5 , so as to prevent the movable plate 5 from falling off the surface of the filter tank 1 when in use.

[0023] A limiting plate 12 is fixedly installed at the bottom of the support rod 6, and the diameter of the limiting plate 12 is larger than the inner diameter of the through groove 7. The support rod 6 is configured to be retractable. When the movable plate 5 moves, the support rod 6 can be elongated and will not fall off from the inside of the through groove 7. At this time, during the movement of the movable plate 5, the installation of the movable plate 5 will not be rotated to change, thereby ensuring that the movable plate 5 and the mounting plate 4 are in an overlapping state in the axial direction of the filter tank 1, thereby ensuring the stability of the filter tank 1 when it is placed horizontally.

[0024] The support rod 6 includes an inner rod 13 and a plurality of sleeves 14 with different inner and outer diameters. The inner rod 13 is movably installed inside the innermost sleeve 14. The plurality of sleeves 14 are movably sleeved and installed. A slide groove 15 is provided on the surface of the inner rod 13 and the sleeve 14. The inner side of the sleeve 14 is fixedly installed and is supported by a slider 16. The slider 16 is installed inside the slide groove 15. The top of the outermost sleeve 14 is fixed on the surface of the movable plate 5. The movement of the slider 16 in the slide groove 15 during the movement of the movable plate 5 can prevent the sleeve 14 from falling off.

[0025] It should be noted that the utility model is a tank body for a filtering device that is easy to maintain. When in use, the movable plate 5 is sleeved on the surface of the filter tank 1, and the mounting plate 4 is directly fixed by welding. Then the support rod 6 is passed through the inside of the through groove 7. At this time, the support rod 6 has a certain guiding effect, which can ensure that the installation position of the movable plate 5 is correct, and finally it is fixed with bolts 10 and nuts 11. When it needs to be placed horizontally for maintenance, the bolts 10 and nuts 11 are loosened, and the movable plate 5 is moved on the surface of the filter tank 1. The support rod 6 can be stretched and will not fall off from the inside of the through groove 7. At this time, in the process of moving the movable plate 5, it will not rotate to change the installation of the movable plate 5, ensuring that the movable plate 5 and the mounting plate 4 are in an overlapping state in the axial direction of the filter tank 1, ensuring the stability of the filter tank 1 when it is placed horizontally.

[0026] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
