Specific embodiment
For the purpose of this utility model, technical solution and advantage is more clearly understood, below in conjunction with attached drawing to this The embodiment of utility model is described in detail.It should be noted that in the absence of conflict, embodiment in the application and Feature in embodiment can mutual any combination.
Embodiment one
A kind of gas mixer, including shell 1 and partition 2 are present embodiments provided, is provided with multiple through-holes on partition 2 21, shell 1 is divided by partition 2 for a mixing chamber 11 and multiple inlet chambers 12 being connected with mixing chamber 11, on mixing chamber 11 It is provided with gas outlet 114, air inlet 121 is provided on inlet chamber 12.
Gas mixer provided in this embodiment includes shell 1 and partition 2, and multiple through-holes 21 are provided on partition 2, is led to The setting in hole 21 makes gas be divided into more parts and enters mixing chamber 11, keeps two or more gases more fully mixed in mixing chamber 11 It closes, shell 1 is divided by partition 2 for a mixing chamber 11 and multiple inlet chambers 12 being connected with mixing chamber 11, on mixing chamber 11 It is provided with gas outlet 114, air inlet 121, gas mixer provided by the embodiment of the utility model are provided on inlet chamber 12 Structure is simple, easy to use, manufacture and use cost are low.
Specifically, as shown in Figure 1, the spacing between adjacent through-holes 21 is equal.
Spacing between adjacent through-holes 21 is equal, so that gas is uniformly passed through partition 2 and flows into mixing chamber 11, and then gas is made to exist The mixing of mixing chamber 11 is more uniform sufficiently.
Further, 2 rows are at least arranged in through-hole 21.
2 rows are at least arranged in through-hole 21 on partition 2, avoid 21 negligible amounts of through-hole from increasing gas flow resistance, influence gas Body mixing efficiency, the through-hole 21 on partition 2, which is set as multirow, can improve the mixed effect of gas.
Preferably, the through-hole 21 on opposite partition 2 is dislocatedly distributed.
Through-hole 21 on opposite partition 2 is dislocatedly distributed, and 21 face of through-hole on opposite partition 2 is avoided, to avoid The gas of opposite inlet chamber 12 generates biggish gas-flow resistance when from aperture entering mixing chamber 11, is conducive to improve gas mixed The efficiency of conjunction.
Further, partition 2 is removably mounted in shell 1.
Partition 2 is removably mounted in shell 1, quantity, aperture and the arrangement side of through-hole 21 on the partition 2 of different size Formula is different, and user can increase gas mixing dress according to the partition 2 of the mixed gas selection different size of different needs The practicability set.
Further, as depicted in figs. 1 and 2, baffle 113 is provided in mixing chamber 11.
Baffle 113 is provided in mixing chamber 11, the setting of baffle 113 is so that flowing of the gas in mixing chamber 11 is hindered Hinder, the flow velocity of gas reduces, and increases incorporation time of the gas in mixing chamber 11, and the inhibition of baffle 113 also makes simultaneously Gas more contacts with each other mixing, improves the effect of gas mixing.
Further, as shown in Figure 1, the not ipsilateral of shell 1 is arranged in gas outlet 114 in air inlet 121.
The not ipsilateral of shell 1 is arranged in gas outlet 114 in air inlet 121, and the two is apart from each other, and this setup is kept away After having exempted from gas from inlet chamber 12 into mixing chamber 11, do not mix in mixing chamber 11 just from the outlet near air inlet 121 sufficiently Mouth 114 exports, to improve the effect of gas mixing.
Further, the shell of gas mixer is metal plate weldment.
The shell of gas mixer keeps device self seal good, no for metal plate weldment using metal plate welding technique It needs additionally to be sealed device, reduces the manufacturing cost of device.
