Abstract
The invention relates to a Roots gas mixing device. The device consists of a main Roots fan, a gas mixing Roots fan and a mixing gas tank, wherein the main Roots fan is provided with a main gas inlet and a main gas outlet; the gas mixing Roots fan is provided with a mixed gas inlet and a mixed gas outlet; the main gas outlet of the main Roots fan and the mixed gas outlet of the gas mixing Roots fan are respectively communicated with the mixing gas tank and main gas and mixed gas enter the mixing gas tank for mixing; the mixing gas tank is provided with a mixing gas outlet; and a Roots rotor of the main Roots fan is connected with a Roots rotor of the gas mixing Roots fan through a coupler. The Roots gas mixing device has the advantages of simple structure, easy implementation, low cost, economy and applicability, and can realize accurate gas mixing and ensure safe and reliable running.
Description
(1) technical field
The present invention relates to gas mixing device, particularly a kind of Roots's gas mixing device.
(2) background technology
Use after in industrial production, usually needing two kinds of gases to mix, for example will utilize liquefied gas and air to mix the mixed air of formation liquefied gas and come instead of natural gas at gas industry; Utilize nitrogen and argon gas to mix the protective gas that carries out gas; Utilize natural gas and medicaments to mix and form the Modern Shipbuilding cutting.The device that mixes for two kinds of gases at present is varied, but all has some problems, as complex structure, cost height, poor stability, metering is not inaccurate or easy to operate etc., needs a kind of simple and practical device accurately to mix gas especially.
(3) summary of the invention
The objective of the invention is at above-mentioned existing problems, a kind of Roots's gas mixing device is provided, simple, the enforcement easily of this apparatus structure, cost is low, economic and practical; Can realize accurately mixing gas, guarantee safe and reliable to operation.
Technical scheme of the present invention:
A kind of Roots's gas mixing device, form by main roots blower, mixed gas roots blower and mixed gas tank, main roots blower is provided with main gas access and main gas vent, mixing the gas roots blower is provided with by mixed gas access with by mixed gas vent, the mixed gas vent of the main gas vent of main roots blower and the quilt of mixed gas roots blower is connected and is entered the mixed air jar with mixed gas tank respectively and mixes, mixed gas tank is provided with the mixed air outlet, and a roots rotor of main roots blower is connected by shaft joint with a roots rotor of mixed gas roots blower.
Operation principle of the present invention:
Roots blower be gas through two 8 opposite font rotors, be in the firm measuring room, make rotor keep correct relative through precision machined adjustment gear.Between rotor, keep best gap, the continuous contactless sealing that this gap provides between rotor and housing, gland.When gas enters roots blower, will promote rotor rotation, whenever rotate a circle just to have and decide volume flow and discharge, Here it is Roots's operation principle from outlet.The rotation of main roots blower drives mixed gas roots blower by shaft joint and rotates synchronously, and the volume of the gas that passes through is certain.Enter the pressure of two roots blower gases by adjusting, can determine to mix the actual ratio of gas, thereby reach the purpose of accurately mixing gas.
Advantage of the present invention is: simple, the enforcement easily of this apparatus structure, and cost is low, economic and practical; Can realize accurately mixing gas, guarantee safe and reliable to operation.
(4) description of drawings
Accompanying drawing is looked schematic diagram for this Roots's gas mixing device master.
Among the figure: 1. main roots blower 2. mixes gas roots blower 3. mixed gas tanks
4. main gas access 5. main gas vents 6. are mixed the gas access
7. mixed gas vent 8. mixed airs and exported 9. shaft joints
(5) specific embodiment
Embodiment:
A kind of Roots's gas mixing device, form by main roots blower 1, mixed gas roots blower 2 and mixed gas tank 3, main roots blower 1 is provided with main gas access 4 and main gas vent 5, mixing gas roots blower 2 is provided with by mixed gas access 6 with by mixed gas vent 7, the mixed gas vent 7 of the main gas vent 5 of main roots blower 1 and the quilt of mixed gas roots blower 2 is connected and is entered mixed air jar 3 with mixed gas tank 3 respectively and mixes, mixed gas tank 3 is provided with mixed air outlet 8, and a roots rotor of main roots blower 1 is connected by shaft joint 9 with a roots rotor of mixed gas roots blower 2.
Claims (1)
1. Roots's gas mixing device, it is characterized in that: form by main roots blower, mixed gas roots blower and mixed gas tank, main roots blower is provided with main gas access and main gas vent, mixing the gas roots blower is provided with by mixed gas access with by mixed gas vent, the mixed gas vent of the main gas vent of main roots blower and the quilt of mixed gas roots blower is connected and is entered the mixed air jar with mixed gas tank respectively and mixes, mixed gas tank is provided with the mixed air outlet, and a roots rotor of main roots blower is connected by shaft joint with a roots rotor of mixed gas roots blower.
