[0034] Embodiment 1

[0035] This embodiment is applicable to gas transportation. The main components of the gas are propane, butane and a small amount of pentane. The molecular weight of these components is much larger than that of air. Therefore, the gas is slightly heavier than air and "sinks" in the air.

[0036] Some fuel gases are relatively clean and can be burned directly without additional filtering. However, some fuel gases contain more dust and other impurities before filtration, which is not conducive to subsequent combustion and needs to be filtered in advance. If the fuel gases are filtered indiscriminately, on the one hand, filtration takes time and cannot meet the use requirements. On the other hand, filtering all of them will accelerate the loss of filtration equipment and increase filtration costs.

[0037] This embodiment reduces the floor space and related supports, saves construction expenses, and integrates the switching device and the filter into one.

[0038] See also Figure 1 This embodiment provides a filtering device, which includes a housing 100, a partition 200, a filtering assembly 300 and a lifting assembly 400.

[0039] In this embodiment, the housing 100 includes a bottom plate 110, a top plate 120, and four side plates respectively vertically adjacent to the top plate 120 and the bottom plate 110, and the four side plates are respectively defined as a first side plate 130, a second side plate 140, a third side plate and a fourth side plate, wherein the first side plate 130 is arranged parallel to the second side plate 140, the third side plate is respectively vertically adjacent to the first side plate 130 and the second side plate 140, and the fourth side plate is arranged parallel to the third side plate.

[0040] The housing 100 is provided with an air inlet 131 and an air outlet 141 . The air inlet 131 is located at the lower portion of the first side plate 130 , and the air outlet 141 is located at the upper portion of the second side plate 140 .

[0041] In some embodiments, the housing 100 is further provided with an inspection port 121 , which is opened on the surface of the housing 100 . Specifically, the inspection port 121 is located on the top plate 120 , which is convenient for operators to perform maintenance work.

[0042] In this embodiment, the filter device is separated from the outside world by the housing 100, so that this embodiment has good mobility and is easy to carry and move.

[0043] The partition 200 is installed in the housing 100, and is provided with an air port 211 and a mounting port 222. The air port 211 extends along a first direction and is circular, and the mounting port 222 also extends along the first direction and is circular. The first direction here is configured as a vertical direction.

[0044] The air inlet 131 is connected to the air outlet 141 through the air outlet 211 .

[0045] Please refer to Figure 1 and Figure 2In some embodiments, the partition 200 includes a first isolation portion 210, a second isolation portion 220 and a third isolation portion 230, the first isolation portion 210 is provided with the above-mentioned air outlet 211, the second isolation portion 220 is provided with the above-mentioned installation port 222, and the first isolation portion 210 and the second isolation portion 220 are respectively horizontally arranged in the shell, and the third isolation portion 230 is respectively vertically adjacent to the first isolation portion 210 and the second isolation portion 220.

[0046] The first isolating portion 210, the second isolating portion 220 and the third isolating portion 230 are in a Z-shaped structure, and the first isolating portion 210, the second isolating portion 220 and the third isolating portion 230 together divide the outer shell 100 into an air inlet chamber 201 and an air outlet chamber 202, the air inlet chamber 201 is located below the outer shell 100, and the air outlet chamber 202 is located above the outer shell 100, that is, the air outlet chamber 202 is located above the air inlet chamber 201. Since the density of the fuel gas is slightly smaller than the density of the air, the fuel gas will not rise freely in the air inlet chamber 201, but needs to continuously introduce fuel gas to generate a certain air pressure to push the fuel gas upward and then be discharged from the air outlet chamber 202. In this embodiment, the air outlet chamber 202 is arranged above the air inlet chamber 201 after the inventor's thinking.

[0047] The filter assembly 300 is located in the air inlet chamber 201, and the filter assembly 300 includes at least one filter element 310. One filter element 310 is installed at a corresponding installation port 222, and the filter element 310 has a preset resistance value, and the filter outlet of each filter element 310 is connected to the air inlet 131; it can be understood that since the rise of the gas requires a certain air pressure, combined with the preset resistance value of the filter element 310, the gas needs to meet certain conditions when passing through the filter element 310, that is, simultaneously satisfying the air pressure condition and the condition of resisting the preset resistance value. Here, these two conditions are used as automatic switching conditions of the filtering device to improve the simplicity and flexibility of this embodiment.

[0048] In some embodiments, the filter assembly 300 includes a plurality of filter elements 310 arranged in an array, and the number of the mounting openings 222 is the same as and corresponds to the number of the filter elements 310. By providing a plurality of filter elements 310, the efficiency of gas filtering can be greatly improved, and the filtering effect can be ensured.

[0049] In actual use, the filter element 310 has a certain service life and needs to be replaced and maintained regularly. As mentioned above, an inspection port 121 is opened on the top plate 120 to facilitate operators to replace and maintain the filter element 310.

[0050] In some embodiments, the filter assembly 300 further includes a filter element pressure plate, a pressure strip, and a sealing element.

[0051] See also Figure 2 , Figure 3 and Figure 4 The lifting assembly 400 includes a valve plate 410, which is located in the air outlet chamber 202. The valve plate 410 moves along a first direction relative to the housing 100 to open or close the air outlet 211. When the valve plate 410 moves upward, the valve plate 410 leaves the first isolation portion 210, thereby opening the air outlet 211. When the valve plate 410 moves downward, the valve plate 410 abuts against the first isolation portion 210, thereby closing the air outlet 211.

[0052] In some embodiments, the movement of the valve plate 410 can be realized by a cylinder 430 or a screw nut or other element with telescopic function to realize the lifting function of the valve plate 410, that is, the upward and downward movement of the valve plate 410. This embodiment takes the cylinder 430 as an example to illustrate as follows:

[0053] The lifting assembly 400 further includes a cylinder fixing seat 420 and a cylinder 430 .

[0054] The cylinder fixing seat 420 is installed on the housing 100 . Specifically, the cylinder fixing seat 420 includes a base 421 and a support 422 . The base 421 is fixedly connected to the top plate 120 , and the support 422 is fixedly connected to the base 421 . The support 422 is located at one end of the base 421 away from the valve plate 410 .

[0055] The cylinder 430 is mounted on the cylinder fixing seat 420. In this embodiment, the cylinder 430 is mounted on the support 422, and the cylinder 430 is provided with a piston rod 431 that moves along a first direction, and the valve plate 410 is located at an end of the piston rod 431 away from the cylinder fixing seat 420. In this embodiment, the downward movement of the valve plate 410 is achieved by extending the piston rod 431, and the upward movement of the valve plate 410 is achieved by retracting the piston rod 431.

[0056] In some embodiments, the lifting assembly 400 also includes a fastener 440, and the cylinder 430 is also provided with a limit block 432, the limit block 432 is installed on the piston rod 431, and the limit block 432 is provided with a limit hole, and the cylinder fixing seat 420 is provided with a first through hole 4221 and a second through hole 4222. In this embodiment, the first through hole 4221 and the second through hole 4222 are located on the support 422, and the second through hole 4222 is arranged at intervals with the first through hole 4221 along the first direction, and the fastener 440 is passed through the first through hole 4221 and the limit hole, or, the fastener 440 is passed through the second through hole 4222 and the limit hole.

[0057] The first through hole 4221 is arranged close to the valve plate 410 relative to the second through hole 4222 . When the limiting hole is aligned with the first through hole 4221 , the valve plate 410 closes the air outlet 211 . When the limiting block 432 is aligned with the second through hole 4222 , the valve plate 410 opens the air outlet 211 .

[0058] Specifically, the piston rod 431 extends to drive the limiting block 432 to move downward until the limiting hole is aligned with the first through hole 4221 , and the fastener 440 is inserted through the first through hole 4221 and the limiting hole to keep the air outlet 211 closed.

[0059] The piston rod 431 retracts, driving the limiting block 432 to move upward until the limiting hole is aligned with the second through hole 4222 , and the fastener 440 is passed through the second through hole 4222 and the limiting hole to keep the air outlet 211 in an open state.

[0060] It can be understood that the movement stroke of the piston rod 431 is equal to the movement stroke of the limit block 432 , and the movement stroke of the limit block 432 is equal to the distance between the first through hole 4221 and the second through hole 4222 .

[0061] In this embodiment, the fastener 440 is used to maintain the open or closed state of the air outlet 211, which can avoid the occurrence of erroneous operation and improve the reliability of switching.

[0062] The cylinder fixing seat 420 is also provided with a guide groove 4223, which extends in a second direction perpendicular to the first direction, and the limit block 432 is slidably arranged in the guide groove 4223 along the first direction. Specifically, the guide groove 4223 is located on the support 422, plays a guiding role, and can prevent the piston rod 431 from deviating and moving.

[0063] Please continue reading Figure 1 and Figure 2 When the air vent 211 is in an open state, since the gas needs to meet the air pressure conditions and resist the preset resistance value conditions at the same time to pass through the installation port 222, the gas will be automatically transported directly from the air vent 211 to the air outlet chamber 202. When the air vent 211 is in a closed state, the gas cannot be output from the air vent 211 and can only be transported from the filter element 310 to the air outlet chamber 202.

[0064] The present application realizes the filtering switching of the filtering device through the lifting component 400. When the air port 211 is opened by the valve plate 410, the air inlet 131 is connected with the air outlet 141 through the air port 211 to realize the direct delivery of the gas. When the air port 211 is closed by the valve plate 410, the air inlet 131 is connected through the air outlet 141 to realize the filtering and delivery of the gas. The switching method is fast and effective, which improves the switching efficiency, reduces the configuration cost, and reduces the floor space, making it more convenient to use.

[0065] In some embodiments, the filtering device also includes a lower ash hopper 500, the opening of which is arranged toward the multiple filter elements 310. When the dust on the filter elements 310 accumulates to a certain amount, it will automatically fall into the lower ash hopper 500 due to gravity, or the operator can shake the filter elements 310 through the inspection port 121 to shake the dust into the lower ash hopper 500. This embodiment can simplify the maintenance work of the filtering equipment by centrally collecting and processing the dust through the lower ash hopper 500.

[0066] See also Figure 1 , Figure 5 and Figure 6 Based on the above content, the method for using the filtering device is further described in this embodiment as follows:

[0067] S100. Gas is introduced from the air inlet 131.

[0068] S200 . Start the lifting assembly 400 to move the valve plate 410 along a first direction relative to the housing 100 to open or close the air port 211 .

[0069] Start the cylinder 430 of the lifting assembly 400, and the cylinder 430 drives the piston rod 431 to extend, thereby driving the limit block 432 to move downward until the limit hole is aligned with the first through hole 4221, and the fastener 440 is inserted into the first through hole 4221 and the limit hole to keep the air outlet 211 in a closed state.

[0070] Start the cylinder 430 of the lifting assembly 400, the cylinder 430 drives the piston rod 431 to retract, and drives the limit block 432 to move upward until the limit hole is aligned with the second through hole 4222, and the fastener 440 is inserted into the second through hole 4222 and the limit hole to keep the air outlet 211 in an open state.

[0071] S300. When the air vent 211 is opened, the gas is directly output from the air outlet 141 through the air vent 211 . When the air vent 211 is closed, the gas is filtered and output from the air outlet 141 after passing through the filter element 310 .

[0072] When the air vent 211 remains in an open state, since the gas needs to meet both the air pressure condition and the condition of resisting the preset resistance value to pass through the filter outlet of the filter element 310, the gas is automatically transported directly from the air vent 211 to the air outlet 141.

[0073] When the air vent 211 remains in a closed state, the gas cannot be output from the air vent 211 and can only be delivered from the filter element 310 to the air outlet 141 .

[0074] This embodiment realizes rapid switching of the gas flow route by rising or falling the valve plate 410. The switching method is simple and fast, and no additional pipelines are required, which reduces the configuration cost, reduces the floor space, and is convenient for operators to use.

[0075] Embodiment 2

[0076] See also Figure 1 Based on the first embodiment, this embodiment provides a filtering system, and the filtering system includes the filtering device of the first embodiment.

[0077] Furthermore, the filtration system further comprises a gas input pipeline and a gas output pipeline, wherein the gas input pipeline is connected to the air inlet 131 of the filtration device, and the gas output pipeline is connected to the air outlet 141 of the filtration device. This embodiment is suitable for working conditions where the gas input pipeline has a large flow rate and a low pressure.

[0078] It can be understood that the gas input pipeline is connected to the external gas source, and the gas output pipeline is connected to the external gas using equipment, so that the gas can be switched to unfiltered or filtered as needed, thereby increasing the service life of the filtering equipment and improving the filtering efficiency.

[0079] Since this embodiment is implemented based on the first embodiment, this embodiment has all the advantages of the first embodiment.
