For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] A filtering detection device according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0032] Reference Figure 1 , Figure 2 and Figure 3 A filtering detection device according to an embodiment of the utility model includes a frame 100, a gas generator to be tested, a gas input pipe 120, a gas receiving pipe 130, a gas detector 140 and a lifting mechanism 150.

[0033] The gas generator 110 to be filtered is disposed on the frame 100 , and the gas generator 110 to be filtered is used to produce and output the gas to be filtered.

[0034] The gas input pipe 120 is arranged on the frame 100, one end of the gas input pipe 120 is used to receive the gas to be filtered from the gas generator 110 to be filtered, and the other end of the gas input pipe 120 is used to seal one end of the tank opening of the filter tank and input the gas to be filtered into the filter tank.

[0035] In some specific embodiments, a first rubber ring 200 is provided at one end of the gas input pipe 120 close to the gas receiving pipe 130, and the first rubber ring 200 is used to abut the tank mouth of the filter tank, so that the first rubber ring 200 can seal the tank mouth of the filter tank, and further, the filtering detection device has a better sealing effect on the tank mouth of the filter tank.

[0036] In some specific embodiments, a switch assembly 210 is provided in the gas input pipe 120, and the switch assembly 210 is used to open or block the gas input pipe 120 from delivering gas to the filter tank. The switch assembly 210 includes a first plate 220 and a second plate 230. The first plate 220 is fixed in the gas input pipe 120 and divides the gas input pipe 120 into an air inlet chamber 240 and an air outlet chamber 250. The air inlet chamber 240 is used to receive the gas to be filtered from the gas generator 110 to be filtered, and the air outlet chamber 250 is used to connect to the filter tank. The first plate 220 has a first air hole 260 connecting the air inlet chamber 240 and the air outlet chamber 250. The second plate 230 is movably arranged on one side of the first plate 220, and the second plate 230 is movable to close or open the first air hole 260.

[0037] It can be understood that by making the second plate 230 movable to close or open the first air hole 260, when the second plate 230 opens the first air hole 260, the gas to be detected can be transported to the filter tank through the first air hole 260. When the detection is completed, the first air hole 260 can be closed by the second plate 230, so that the gas delivery pipe stops transporting the gas to be detected, thereby avoiding the gas to be detected from being released from the gas input pipe 120 to the external polluted environment when the filter tank is disassembled and replaced.

[0038] Furthermore, the second plate 230 is connected to the first plate 220 by sliding up and down, and the switch assembly 210 also includes a first cylinder 270, which is fixed on the top of the gas input pipe 120, and the telescopic rod of the first cylinder 270 passes through the gas input pipe 120 and is connected to the second plate 230, and the first cylinder 270 is used to drive the second plate 230 to rise and fall, and the second plate 230 rises and falls to close or open the first air hole 260, thereby making the filtering detection device more automated in driving the second plate 230.

[0039] The gas receiving tube 130 is movably arranged on the frame 100, and the gas receiving tube 130 can be close to and away from the gas input tube 120. A filter tank is accommodated between the gas receiving tube 130 and the gas input tube 120. One end of the gas receiving tube 130 is used to seal the end of the filter tank away from the gas input tube 120 and receive the gas filtered by the filter tank.

[0040] In some specific embodiments, an exhaust fan 280 is provided in the gas receiving tube 130, and the exhaust fan 280 is used to draw the gas in the filter tank to the gas receiving tube 130, thereby accelerating the flow rate of the gas in the filter tank, making the filtering speed of the filter tank faster, and further improving the efficiency of the filtering detection device.

[0041] Furthermore, the exhaust fan 280 is located at one end of the gas receiving tube 130 close to the filter tank, so that the exhaust fan 280 can be closer to the filter tank, and further, the exhaust fan 280 has a better suction effect on the gas in the filter tank.

[0042] In some specific embodiments, at least two parallel guide rails 290 are provided on the frame 100, and a plurality of rollers 300 are provided at the bottom of the gas receiving tube 130. The rollers 300 roll on the guide rails 290, thereby reducing the resistance of the gas receiving tube 130 during movement and making the movement of the gas receiving tube 130 smoother.

[0043] Furthermore, a second cylinder 310 is also provided on the frame 100, and the second cylinder 310 is used to drive the gas receiving tube 130 to approach and move away from the gas input tube 120, so that the second cylinder 310 can apply pressure to the filter tank when the filter tank filters the gas, and then, the filter detection device can keep the tank mouth of the filter tank sealed when the filter tank filters the gas, thereby avoiding gas leakage from the filter tank.

[0044] In some specific embodiments, a second rubber ring is provided at one end of the gas receiving tube 130 close to the gas input tube 120, and the second rubber ring is used to abut the tank mouth of the filter tank, so that the second rubber ring can seal the tank mouth of the filter tank, and further, the filtering detection device has a better sealing effect on the tank mouth of the filter tank.

[0045] In some specific embodiments, the gas receiving tube 130 has an exhaust port at one end away from the gas input tube 120 , and the exhaust port is provided with an exhaust switch, which is used to seal and open the exhaust port, thereby facilitating rapid exhaust of the gas receiving tube 130 .

[0046] The gas detector 140 is used to detect the content of toxic substances in the gas in the gas receiving tube 130 .

[0047] In this embodiment, a gas generator 110 to be filtered, a gas input pipe 120, a gas receiving pipe 130 and a gas detector 140 are arranged on a frame 100. It can be understood that the gas receiving pipe 130 can be close to and away from the gas input pipe 120, so that the gas receiving pipe 130 and the gas input pipe 120 can cooperate to clamp and release the filter tank, thereby facilitating the clamping and disassembly of the filter tank. In addition, the gas to be filtered produced by the gas generator 110 to be filtered is input into the filter tank through the gas input pipe 120 for filtration, and then the filtered gas flows into the gas receiving pipe 130. The gas detector 140 detects the filtering effect of the filter tank by detecting the content of toxic substances in the gas in the gas receiving pipe 130, thereby realizing the detection of the filtering effect of the filter tank by the filtering detection device.

[0048] As for the lifting mechanism 150, the lifting mechanism 150 is arranged between the gas input pipe 120 and the gas receiving pipe 130. The lifting mechanism 150 includes a support frame 160 that is slidably arranged on the frame 100 up and down, and a first screw 170 that drives the support frame 160 to rise and fall. The first screw 170 is rotatably connected to the frame 100, and the first screw 170 is threadedly connected to the support frame 160. The support frame 160 is used to support and lift the filter tank. The support frame 160 has an avoidance space, and the avoidance space is used to avoid the transporting tools for transporting the filter tank.

[0049] It is understandable that when a transport tool is used to transport the filter tank to the filter detection device, the avoidance space can avoid the transport tool, so that the filter tank can be transported between the gas input pipe 120 and the gas receiving pipe 130, and then the first screw 170 drives the support frame 160 to rise, so that the support frame 160 drives the filter tank to rise to the installation height to align the gas input pipe 120 and the gas receiving pipe 130, and then the gas receiving pipe 130 is close to the gas input pipe 120, so that the gas receiving pipe 130 cooperates with the gas input pipe 120 to clamp the filter tank, thereby, when aligning and clamping the filter tank, it is unnecessary to carry it manually or adjust the height of the filter tank with the help of external tools, so that the clamping operation of the filter tank is easier.

[0050] In some specific embodiments, the support frame 160 includes a crossbeam 180 and two support arms 190 arranged on one side of the crossbeam 180. The crossbeam 180 is slidably connected to the frame 100 up and down. The two support arms 190 cooperate to support the filter tank, and an avoidance space is formed between the two support arms 190.

[0051] It is understandable that by providing two support arms 190 on one side of the crossbeam 180 , it is possible to avoid the crossbeam 180 interfering with the transport tool and the filter tank, thereby making the structural arrangement of the support frame 160 more reasonable.

[0052] In some specific embodiments, two gas input pipes 120 are provided, and the two gas input pipes 120 are respectively provided on both sides of the gas generator to be filtered 110, and two gas receiving pipes 130, gas detectors 140 and lifting mechanisms 150 are correspondingly provided. A shunt pipe 320 is provided between the gas generator to be filtered 110 and the two gas input pipes 120, and the shunt pipe 320 includes a main pipe part 330 and two U-shaped pipe parts 340 connected to the main pipe part 330, the main pipe part 330 is connected to the gas generator to be filtered 110, and the two U-shaped pipe parts 340 are respectively connected to the two gas input pipes 120.

[0053] It can be understood that, by enabling one gas generator 110 to supply gas to two gas input pipes 120, the filter detection device can detect two filter tanks at the same time, thereby improving the detection efficiency.

[0054] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0055] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
