Problems solved by technology

However, the diffusion tube currently used in equipment such as compact spinning or compact spinning, because it is installed at the lower part of the gap between the two rows of roving spindles or supporting spindles on the spinning locomotive, has a small space and cannot pass the diffusion length H. 1 To achieve continuous, uniform and stable fluid, if not solved, it will directly affect the output and quality of the final product

Embodiment Construction

[0013] A new type of flow field uniform diffuser placed in the lower part of the gap between two rows of roving spindles or supporting spindles on the compact spinning or compact spinning equipment. 2.50 meters, the height c of the diffusion pipe 23 is 0.20 to 5.00 meters, and there are air inlets 21 and air outlets 22. The first equalizer A with rectangular holes is arranged in the diffusion pipe 23, and the first equalizer A with rectangular holes is arranged in the diffusion pipe 23. The length a of an equalizer plate A 1 0.30 to 25.50 meters, the width b of the first equalizer A with rectangular holes 1 0.10 to 2.50 meters, the thickness w of the first equalizer A with rectangular holes 1 0.50-1.50 mm, the height c of the first equalizer plate A with a rectangular hole from the upper surface of the diffuser pipe 23 1 It is 0.10 to 2.50 meters, and its periphery is connected with the inner wall of the diffuser tube 23; in the diffuser tube 23, there are also 4 steel wires...

Abstract

This invention discloses a new type of flow field uniform diffuser. Apart from the new design to the diameter of the tube, it utilizes the turbulent flow diffusion theory of the flow field to build up an idea of setting a first and a second uniform flow boards with rectangular holes in the diffusion tube on the basis of the current inlet, outlet and diffusion tubes which has the advantages of short uniform flow length, uniform flows and small occupied space.

Description

Technical field: [0001] The invention belongs to the application field of textile fluid mechanics, and relates to a novel flow field uniform diffuser. technical background: [0002] In many workplaces, the stability of the flow field directly affects the stability of the working state. The change of the fluid state of the existing uniform flow field diffuser 1 is by extending the diffusion length H of the diffuser pipe 13 1 To achieve uniform and continuous stability of the flow field, such as figure 1 As shown, the usual diffuser length H 1 It is three times the equivalent diameter of the diffusion area. However, the diffusion tube currently used in equipment such as compact spinning or compact spinning, because it is installed at the lower part of the gap between the two rows of roving spindles or supporting spindles on the spinning locomotive, has a small space and cannot pass the diffusion length H. 1 To achieve continuous, uniform and stable fluid, if not solved, it...
