Description

Technical Field

[0001] The utility model belongs to the technical field of gas mixing, in particular to a gas mixing device. Background Art

[0002] A mixed gas is a gas containing two or more active components, or a non-active component whose content exceeds a specified limit. Mixtures of several gases are commonly used as working fluids in engineering. Mixed gases are often studied as ideal gases. Mixing two gases requires a gas mixing device.

[0003] In the prior art, a gas mixing device with the announcement number CN214319828U includes a bottom plate, support plates are vertically installed at both ends of the top of the bottom plate, a mixing cylinder is horizontally installed between the two support plates, an air intake mechanism is provided at the top of the mixing cylinder, an exhaust mechanism is provided at the bottom of the mixing cylinder, and a rotating shaft is installed horizontally inside the mixing cylinder. One end of the rotating shaft passes through the mixing cylinder and the support plate in sequence, and a motor is fixedly installed at the end. Pushing mechanisms are symmetrically arranged on the outside of both ends of the rotating shaft. The utility model can drive two mutually symmetrical pushing mechanisms to circulate and push the gas inside the mixing cylinder by providing a motor and a rotating shaft, thereby improving the mixing efficiency and mixing uniformity between the gases. The gas mixing device solves the problem of low mixing efficiency.

[0004] Although the above utility model patent solves the problem of low mixing efficiency, it does not have the function of filtering the gas, does not have the function of facilitating the cleaning of impurities on the filter plate, and does not have the function of increasing the mixing area. During use, the gas may contain some impurities. If the gas cannot be filtered, the mixed gas will be impure, resulting in poor mixing effect of the device. After long-term use, more impurities will accumulate on the filter plate. If the impurities on the filter plate are not cleaned for a long time, the impurities will accumulate and clog the filter plate, making the filter plate unable to be used normally or the filtration efficiency will be reduced, making the practicality of the device poor. If the mixing area between the gases cannot be increased, the gases may not be mixed evenly, resulting in poor mixing effect of the device. The patent also does not have the function of controlling the gas flow rate. During use, appropriately increasing the gas flow rate can enhance the turbulence between the gases, thereby promoting wider mixing. If the gas flow rate cannot be controlled, uneven gas mixing may occur, resulting in poor mixing effect of the device. Utility Model Content

During use, the gas is filtered by the arranged filter plate, and the impurities on the filter plate are cleaned by starting the motor to drive the push plate to move. The flow path of the gas is changed by the arranged guide plate, and the collision and contact opportunities between the gases are increased, which can avoid the situation that the mixed gas is impure due to the inability to filter the gas, thereby ensuring the mixing effect of the equipment, and also avoid the situation that the impurities on the filter plate are not cleaned for a long time, resulting in the accumulation and clogging of the filter plate, thereby making the filter plate unable to be used normally or the filtration efficiency lowered, thereby ensuring the practicability of the equipment, and also avoid the situation that the gases are not evenly mixed due to the inability to increase the mixing area between the gases, thereby ensuring the mixing area of the equipment.

[0018] The utility model can achieve the effect of appropriately increasing the gas flow rate by setting the flow rate control mechanism. During use, by starting the blower, the blower sucks the gas inside the shell into the pipe and then discharges it from the other end of the pipe, thereby controlling the gas flow rate. This can avoid the situation where uneven gas mixing may occur due to the inability to control the gas flow rate, thereby ensuring the mixing effect of the equipment.
