The filtering device 100 can simultaneously realize two functions of gas conveying and gas filtering, and the two functions are independent and do not interfere with each other, so that the pollution of gas is effectively avoided, and the filtering effect is improved. Wherein usable gas delivery function of filter equipment 100 is to the gas transmission apparatus conveyor gas such as puncture ware to and is received the smog that gas transmission apparatus collector of discharging fume, realizes filtering for the first time through gas filtering function, and the gaseous process after the first filtration accessible filter equipment 100 carries once more to realize endless effect, thereby promote the ability of gas recovery, reach reduce cost's purpose, and prevent to have the smog of a large amount of cell pieces and virus, its direct row causes the potential safety hazard in the operating room. The filter device 100 of the present embodiment can be applied to a cavity mirror smoke circulating system, but is not limited thereto, and the details of the filter device will be described below by taking the cavity mirror smoke circulating system as an example.
First embodiment
As shown in fig. 1 to 4, the filtering apparatus 100 includes:
a filter housing 110, said filter housing 110 having a filter gas transmission chamber 1101 and a filter smoke exhaust chamber 1102 isolated from each other;
a first connection assembly 120, said first connection assembly 120 being disposed at one end of said filter housing 110 and having a gas delivery outlet portion 1201 and a smoke exhaust inlet portion 1202, said gas delivery inlet portion 1201 communicating with said filter gas delivery chamber 1101, said smoke exhaust inlet portion 1202 communicating with said filter smoke exhaust chamber 1102;
a second connecting assembly 130, said second connecting assembly 130 being arranged at the other end of said filter housing 110, facing away from said first connecting assembly 120, and having a gas inlet portion 1301 and a smoke outlet portion 1302, said gas inlet portion 1301 communicating with said filter gas chamber 1101, said smoke outlet portion 1302 communicating with said filter smoke chamber 1102;
at least one filter element 140, said filter element 140 being arranged within said filter smoke evacuation chamber 1102, wherein at least one said filter element 140 is connected to said smoke evacuation outlet portion 1302 remote from said smoke evacuation inlet portion 1202 such that a gap exists between said filter element 140 and said smoke evacuation inlet portion 1202.
The gas enters the filtering gas transmission chamber 1101 through the gas transmission inlet part 1301, and then is introduced into the gas transmission smoke exhaust device for use through the gas transmission outlet part 1201, wherein the gas to be transmitted can be pure CO2 gas. The smoke collected by the gas delivery and smoke evacuation apparatus enters the filtering and smoke evacuation chamber 1102 through the smoke evacuation inlet portion 1202, is primarily filtered by the filter element 140, and is then exhausted through the smoke evacuation outlet portion 1302, thereby performing both gas delivery and gas filtration functions. In addition, since the filter element 140 is disposed away from the smoke exhaust inlet portion 1202, the introduced smoke firstly enters the filtering smoke exhaust chamber 1102 and then is filtered by the filter element 140 until the introduced smoke is exhausted from the smoke exhaust outlet portion 1302, the reaction time of the smoke and the filter element 140 is prolonged, the filtering effect is further improved, and the safety of gas circulation is further ensured.
As can be seen from the above, the smoke inlet portion 1202 and the smoke outlet portion 1302 are disposed at two ends of the filtering smoke evacuation chamber 1102 and are connected to each other. The gas transmission outlet part 1201 and the gas transmission outlet part 1201 are arranged at two ends of the filtering gas transmission chamber 1101 and are communicated with each other. The filtering gas transmission chamber 1101 only serves to transmit gas, such as pure CO2 gas, but sheet-shaped filter elements may be disposed on the gas transmission outlet portion 1201 and the gas transmission outlet portion 1201 to further ensure the purity of the gas transmitted through the filtering gas transmission chamber 1101.
As shown in fig. 1, 4 and 5, the filter housing 110 includes a filter tube 111, a first cover plate 112, a second cover plate 113 and a partition plate 114, the filter tube 111 is hollow, the first cover plate 112 and the second cover plate 113 are hermetically connected to both ends of the filter tube 111, and the partition plate 114 is disposed on the filter tube 111 to divide the inside of the filter tube 111 into the filter gas transmission chamber 1101 and the filter smoke discharge chamber 1102.
Specifically, the partition plate 114 extends in the axial direction of the filtering pipe 111, and two ends of the partition plate 114 are flush with two ends of the filtering pipe 111, so that when the first cover plate 112 and the second cover plate 113 are connected to two ends of the filtering pipe 111 in a closed manner, the filtering gas transmission chamber 1101 and the filtering smoke exhaust chamber 1102 are independent and isolated from each other, thereby preventing gas streaming and causing pollution. Wherein the partition plate 114 can be integrally formed with the filtering pipe 111 or detachably connected thereto, and the first cover plate 112 and the second cover plate 113 can be connected to both ends of the filtering pipe 111 by fastening, screwing or integrally forming, so that the assembly is convenient and fast, and the filtering casing 110 has a simple structure and is easy to form.
More specifically, since the cross section of the filtering pipe 111 is circular, the cross section of the filtering gas transmission chamber 1101 and the cross section of the filtering smoke discharge chamber 1102 which are formed by dividing are both semicircular, referring to fig. 6. Since the filter element 140 and the like are required to be disposed in the filtering and exhausting chamber 1102, it needs enough space to filter impurities, and the filtering and gas-transferring chamber 1101 is only used for transferring gas, it can be seen that the volume of the filtering and exhausting chamber 1102 is larger than that of the filtering and gas-transferring chamber 1101, and preferably, the ratio of the volume of the filtering and exhausting chamber 1102 to that of the filtering and gas-transferring chamber 1101 is larger than 3: 1.
As shown in fig. 1 and 2, the first connection assembly 120 is disposed on the first cover plate 112, and includes a connection inner tube 121 and a connection outer tube 122 arranged from inside to outside, and the connection inner tube 121 and the connection outer tube 122 may be concentrically disposed. Wherein the smoke inlet portion 1202 is located in the area enclosed by the inner connecting tube 121, and the gas delivery outlet portion 1201 is located in the area enclosed between the inner connecting tube 121 and the outer connecting tube 122, i.e. the gas delivery outlet portion 1201 is located outside the smoke inlet portion 1202. By arranging the connecting inner pipe 121 and the connecting outer pipe 122 to separate the gas delivery outlet part 1201 and the smoke exhaust inlet part 1202, not only is pipeline connection facilitated, but also the situation of connection errors is effectively prevented, so that the reliability and safety of gas delivery are improved. In addition, the inner connecting tube 121 and the outer connecting tube 122 may be provided with a first connecting plug 123, so that when the filter device 100 is not in use, the gas delivery outlet 1201 and the smoke exhaust inlet 1202 are sealed by the first connecting plug 123, thereby maintaining the sanitation of the interior of the filter device 100.
With continued reference to fig. 2, the gas delivery outlet 1201 and the smoke exhaust inlet 1202 are disposed on both sides of the partition 114 while being offset from the center of the first connection assembly 120 such that the gas delivery outlet 1201 and the smoke exhaust inlet 1202 are separated, further preventing a connection error.
As shown in fig. 2, 4 and 5, the filtering shell 110 further includes an air blocking connection block 115, the air blocking connection block 115 is connected to the partition 114 and disposed in the filtering and smoke exhausting chamber 1102, an air blocking and smoke exhausting port 11511 communicating the filtering and smoke exhausting chamber 1102 with the smoke exhausting inlet portion 1202 is opened on the air blocking connection block 115, and an air blocking and gas transferring port 11521 communicating the filtering and gas transferring chamber 1101 with the gas transferring outlet portion 1201 is opened on the air blocking connection block 115.
