Embodiment 1

[0022] Such as figure 1 As shown, the conical air inducer includes a conical inducer 1, a spherical casing 2, a connecting frame 3 and an air intake pipe 4.

[0023] The conical inducer 1 is conical, with a Coanda curved surface 11 on its side wall, and a convex curved surface 12 on its bottom surface. The curved surface 12 and the Coanda curved surface 11 transition smoothly.

[0024] One end of the spherical case 2 is provided with an air inlet, and the other end is provided with an air outlet. The spherical case 2 is connected to the conical inducer 1 through a connecting frame 3, and its air outlet is facing the arc surface of the conical inducer 1, and is connected with the conical inducer 1. An annular air outlet 10 is formed between the conical inducers.

[0025] Connector 3 comprises main rod 31, branch rod 32 and connecting plate 33; A plurality of branch rods 32 are circularly evenly distributed around the center line of main rod 31 and welded on one end of main rod...

Embodiment 2

[0029] Such as Figure 4 As shown, the only difference between this embodiment and Embodiment 1 is that the conical air inducer also includes a fan 6, and the fan 6 is installed in the intake pipe 4 through a bracket.

[0030] In this embodiment, the intake pipe 4 can be designed as a straight pipe or a curved pipe according to actual needs. When the air intake pipe 4 is a straight pipe, it can be used independently as an air induction device. see Figure 5 , when the inlet pipe 4 is an elbow, it is used for gas drainage in the pipeline, the inlet end of the inlet pipe 4 bends and passes through the pipeline 9 walls, and the bending angle of the inlet pipe 4 is a, and a is 90°.

[0031] The principle of the present invention is: under the action of the fan or high-pressure air source, the gas enters the spherical casing 2 from the inlet pipe 4, and finally forms a high-speed air flow area at the air outlet 10; The negative pressure zone is created, so that the surrounding g...

Abstract

The invention discloses a conical air inducing machine. The conical air inducing machine comprises a conical inducing body, a spherical cover shell, a connecting frame and an intake pipe; the conicalinducing body is conical; a Kornda curved surface is arranged on the side wall surface of the conical inducing body; the bottom surface of the conical inducing body is an arc surface outwards projected; the arc surface is smoothly transited with the Kornda curved surface; an air inlet is formed in one end of the spherical cover shell, and an air outlet is formed in the other end; the spherical cover shell is connected to the conical inducing body through the connecting frame; the air outlet thereof is aligned to the arc surface of the conical inducing body; an annular air outlet is formed between the spherical cover shell and the conical inducing body; one end of the intake pipe is an air inlet end, and the other end is an air outlet end; and the air outlet end is connected to the air inlet of the spherical cover shell. When the conical air inducing machine based on the Kornda effect is used as an independent air inducing device in space, low-flow and low-power induced exhausting can be realized; the inducing rate is high up to 10-15 times; and surrounding air can be centralized in a front edge columnar area of the conical inducing body 1 for ejection, so that the flow of air currents on this straight line can be greatly improved.

Description

technical field [0001] The invention relates to the fields of fluid machinery and fluid distribution, in particular to a conical air inducer. Background technique [0002] At present, the injection in the pipeline is a very mature technology, but the pipeline air inducer that can concentrate the flow on a straight line is still relatively rare. The airflow in the pipeline is usually guided by the fan. On the premise that the shape of the pipeline is determined, the power of the fan determines the flow rate of the airflow in the pipeline. In the application scenario with a fast flow rate, a high-power fan is usually used for drainage to achieve the required airflow velocity in the pipe, and the power consumption of a high-power fan is relatively large. 2. The air inlet and outlet of the fan are directly connected to the inner cavity of the pipe. In some application scenarios, high temperature, high humidity or polluted gas (such as gas containing oily smoke or dust) circulat...
