AI Technical Summary
Existing gas mixers are expensive and difficult to manufacture, and the irregular shape of the Venturi device makes manufacturing difficult.
The inner tube and the outer tube form a jacket structure, which, together with the sealing plate, flow equalization plate and guide fluid, ensures that the gas is uniformly mixed on the outside of the inner tube, and the mixed gas is guided into the jacket by the guide fluid to enhance the mixing uniformity.
This achieves uniform gas mixing and simplifies the manufacturing process, reducing production costs.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to gas mixing field, concretely relates to a gas mixing equipment technology. BACKGROUND
[0002] Gas mixer is a kind of gas mixing device widely used in various fields;Common such as natural gas and air, propane and oxygen etc.;At present, gas mixer mainly adopts venturi injection;But this structure needs larger long neck ratio, and venturi device shape is irregular and not easy to make. SUMMARY
[0003] The utility model provides a new gas mixing device, to solve the technical problem of current technology high production cost, production difficulty etc.
[0004] Gas mixer includes inner tube 1, sleeve 2, flow guide 3, connector 4, inner tube 1 outside still is connected with the baffle 11, the flow equalizing plate 12, the nozzle 13;Wherein inner tube 1 and sleeve 2 form the jacket, and by the baffle 11 to the both ends of jacket sealing, prevent the jacket leakage to outside;In the jacket, between two baffle 11 still be equipped with the flow equalizing plate 12, its function is to make the gas that connector 4 is introduced in the outer side of inner tube 1 flow equalizing, make this gas can pass through the nozzle 13 and another gas more evenly mix.
[0005] Flow guide 3 is equipped in the jacket rear end formed by inner tube 1 and sleeve 2, and flow guide is composed of cylindrical body 32 and the flow guide cone 31 at both ends, and the flow guide fin 33 in the periphery;When two kinds of gas are initially mixed in inner tube 1, mixed gas will be guided to the interlayer between flow guide 3 and sleeve 2 by flow guide 3, and flow through flow guide fin 33, make the mixing of two kinds of gas more evenly.
[0006] This gas mixing device gas mixing stroke proportion is long, simultaneously through the structure guaranteeing the uniformity of gas distribution, increase airflow disturbance, guarantee the uniformity of gas mixing;Meanwhile, the device is composed of common material, no special structure;Therefore, the device is simple to manufacture, and the production cost is low. BRIEF DESCRIPTION OF DRAWINGS
[0007] Figure 1 It is the sectional view of the utility model gas mixing device, and the serial number in the drawing is: 1-inner tube, 2-sleeve, 3-flow guide, 4-connector, 11-baffle, 12-flow equalizing plate, 13-nozzle, 13-cone, 32-cylindrical body, 33-flow guide fin. DETAILED DESCRIPTION
[0008] The technical scheme in the utility model embodiment will be described clearly and completely below. Figure 1 The technical scheme in the utility model embodiment will be described clearly and completely below.
[0009] As shown in the accompanying Figure 1 The gas mixing device is used to mix two different gases.
[0010] The gas mixer comprises an inner tube 1, a sleeve 2, a flow guide 3, a connecting pipe 4, and the inner tube 1 is further connected with a sealing plate 11, a flow equalizing plate 12 and a nozzle 13; wherein the inner tube 1 and the sleeve 2 form a jacket, and the jacket is sealed at both ends by the sealing plate 11 to prevent gas leakage.
[0011] The flow equalizing plate 12 is further arranged between the two sealing plates 11 in the jacket, which is used to make the gas introduced by the connecting pipe 4 flow evenly outside the inner tube 1, so that the gas can enter another gas for mixing more evenly through the nozzle 13; in order to ensure the flow equalizing effect, the flow equalizing plate 12 can be provided with one or more plates, or can not be provided if the space is limited; in addition, the nozzles 13 are also arranged on the circumference of the inner tube 1 at intervals, and the direction of the nozzles can be perpendicular to the axis of the inner tube 1, or the gas can be obliquely sprayed into the inner tube 1 along the inner wall of the inner tube 1; in order to further reduce the difficulty and cost of production, the nozzles 13 can be cancelled and replaced by holes; the direction of the holes is the same as that of the nozzles 13, which can be perpendicular to the axis of the inner tube 1, or can be obliquely arranged along the inner wall of the inner tube 1.
[0012] The flow guide 3 is arranged at the rear end of the jacket formed by the inner tube 1 and the sleeve 2, and the flow guide 3 is composed of a cylindrical body 32, two flow guide cones 31 at both ends, and a flow guide fin 33 on the periphery; after the two gases are preliminarily mixed in the inner tube 1, the mixed gas will be guided into the interlayer between the flow guide 3 and the sleeve 2 by the conical body 31, so that the flow rate of the mixed gas is increased and the thickness is reduced, which is beneficial to the full mixing of the two gases; at the same time, when the mixed gas flows through the flow guide fin, the degree of disorder of the mixed gas will be further increased, so that the mixing of the two gases is more uniform; the flow guide 3 should be arranged at the rear end of the jacket formed by the inner tube 1 and the sleeve 2, if it is arranged in the inner tube 1, the flow rate of the mixed gas will be further increased, and the resistance loss will also continue to increase; if the flow rate is ensured in the inner tube 1, the size of the device will be further increased; therefore, it is a more reasonable method to arrange the flow guide 3 at the rear of the jacket; further, the included angle α between the flow guide fin 33 on the periphery of the flow guide 3 and the axis of the cylindrical body 32 satisfies 0°<α<90°.
[0013] The above description is only the preferred embodiment of the present disclosure and the explanation of the applied technical principles; those skilled in the art should understand that the range of the utility model disclosed in the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or equivalent features without departing from the concept of the utility model.
