DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 In this embodiment, a filtering gas pressure pipeline connector includes an air pipe 1. The top of the air pipe 1 is threadedly connected to a filter mechanism 3 that penetrates into the interior thereof. The filter mechanism 3 is used to filter impurities in the gas. The outer surface of the filter mechanism 3 is detachably connected to a connecting seat 4. It should be noted that an external thread is fixed on the outer surface of the connecting seat 4, and the external thread can be connected to the air supply pipeline. A first mounting portion and a second mounting portion are fixed on the outer surface of the connecting seat 4. The first mounting portion and the second mounting portion can be respectively connected to two pipes of different diameters, which is convenient for splicing and air supply.

[0021] In addition, the outer surface of the trachea 1 is threadedly connected to a stabilizing sleeve 2 that is threadedly connected to the outer surface of the connecting seat 4. The stabilizing sleeve 2 can tightly fix the connecting seat 4 and the trachea 1 and can be disassembled in the reverse direction. A plurality of exhaust holes 5 are provided on the top of the trachea 1, and the exhaust holes 5 can discharge gas. A connecting head 6 is fixed on the top of the trachea 1. It should be noted that an internal thread is fixed on the inner surface of the connecting head 6, and the internal thread can be connected to a gas transmission pipeline. The inner cavity of the connecting head 6 is provided with a first mounting groove and a second mounting groove. The first mounting groove and the second mounting groove can respectively connect to two pipelines of different diameters, which is convenient for inputting and filtering the gas.

[0022] In addition, a non-return mechanism 7 is fixed on the inner surface of the connector 6. The non-return mechanism 7 can reproduce the adverse effects of gas backflow. It should be noted that the non-return mechanism 7 includes a non-return tube fixed on the inner surface of the connector 6. A non-return ring is fixed on the inner surface of the non-return tube. The non-return ring can limit the passage of airflow and accelerate the airflow to rush upward. The left and right side walls on the inner side of the non-return tube are hinged with hollow rods. The hollow rods are hollow structures, and the interior of the solid rods can accommodate reciprocating sliding of the solid rods.

[0023] It needs to be further explained that the inner surface of the hollow rod is slidably connected to the solid rod. After being squeezed, the solid rod slides into the inner cavity of the hollow rod, shortening the total length of the two, thereby changing their total length. A limit plate is fixed on the top of the solid rod, and the limit plate can limit the sliding of the solid rod to prevent the solid rod from completely sliding out of the inner cavity of the hollow rod. A check plate is hinged on the opposite side of the two solid rods, and the position of the check plate can be changed by the impact of airflow. A check plug matching the check ring is fixed to the bottom of the check plate, and the size of the check plug matches the check ring, so that the check plug can be stuck into the inner surface of the check ring.

[0024] During operation, the gas transmission pipe and the gas delivery pipe are fixed to the connecting seat 4 and the connecting head 6 respectively, and the gas is introduced into the filtering mechanism 3, through which impurities and dust are filtered out, and then discharged upward through the non-return mechanism 7.

[0025] See also Figure 2-3 In order to filter out impurities in the gas, the filtering mechanism 3 in this embodiment includes a filter cartridge 301 which is threadedly connected to the bottom of the air pipe 1 and penetrates into the interior thereof. A dust hopper 302 is fixed to the inner surface of the filter cartridge 301. The dust hopper 302 can create a windproof area through its structural enclosure after the gas enters the filter cartridge 301, so that dust falls into it and accumulates. The top of the filter cartridge 301 is detachably connected with a filter tube 303 which penetrates into the outside thereof. The filter tube 303 can be fixed with a gas separator 304 at the bottom of the filter tube 303. The gas separator 304 can impact and separate the gas filled in the filter cartridge 301 through its conical outer surface.

[0026] Furthermore, a plurality of air holes 305 are provided on the outer surface of the filter tube 303, and a filter assembly 306 is fixed on the inner surface of the filter tube 303. It should be noted that the filter assembly 306 includes a fixing seat 3061 fixed on the inner surface of the filter tube 303, and a filter plate 3062 is fixed on the inner surface of the fixing seat 3061. The filter plate 3062 plays a supporting role, and the activated carbon tube 3064 and the filter cotton tube 3065 inside are separated by the filter plate 3062, and filtering is performed in sequence.

[0027] It should also be noted that a plurality of filter holes 3063 are provided on the top of the filter plate 3062, and the gas enters the activated carbon tube 3064 from the filter cotton tube 3065 through the filter holes 3063. The activated carbon tube 3064 and the filter cotton tube 3065 are respectively fixed to the top and bottom of the filter plate 3062. If there is dust or metal debris in the pipeline, it can be filtered out by the filter cotton tube 3065 and enter the activated carbon tube 3064 through the multiple filter holes 3063, so that the activated carbon tube 3064 further adsorbs and filters the gas and absorbs other volatile components mixed in.

[0028] In general, the gas introduced into the filter cartridge 301 is dispersed by the gas distributor 304 and falls into the variable groove of the dust collector 302, and the gas enters the filter tube 303 through multiple air holes 305, filters out impurities through the filter cotton tube 3065, and is introduced into the activated carbon tube 3064 through the filter hole 3063, and is discharged after the volatile gas impurities are adsorbed and filtered out.

[0029] The working principle of the above embodiment is:

[0030] (1) During the installation process, the filter cartridge 301 is inserted into the air pipe 1, and its bottom is connected to the connecting seat 4. The stabilizing sleeve 2 is twisted by threads to move it downward, and is threadedly connected to the connecting seat 4 to fix it firmly. It can be removed by reverse operation. No other parts need to be assembled, and disassembly and assembly are convenient.

[0031] (2) During use, the gas can be introduced into the filter cartridge 301 by fixing the gas transmission pipe and the air delivery pipe to the connecting seat 4 and the connecting head 6 respectively. The gas is dispersed by the gas distributor 304, and some dust falls into the dust collecting area of ​​the dust hopper 302. The gas enters the filter tube 303 through multiple air holes 305, and the impurities are filtered out through the filter cotton tube 3065. The gas is introduced into the activated carbon tube 3064 through the filter hole 3063. After the volatile gas impurities are adsorbed and filtered out, the gas is impacted upward through the check plug, and the solid rod is affected by the check plate to change its hinge angle and slide into the hollow rod under force. The gas is discharged upward and cannot flow back due to the resistance. The impurities in the gas can be filtered out efficiently, making the experimental data more accurate.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
