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] The flow field uniform diffuser placed in the lower part of the gap between the two rows of roving spindles or spindle holders on the compact spinning or compact spinning equipment, the length a of the diffuser tube 23 is 0.30-25.50 meters, and the width b of the diffuser tube 23 is 0.10-2.50 meters m, the height c of the diffusion pipe 23 is 0.20 to 5.00 meters, and there is an air inlet 21 and an air outlet 22, and the first equalizer A with a rectangular hole is arranged in the diffusion pipe 23, and the first equalizer A with a rectangular hole is arranged in the diffusion pipe 23. The length of equalizer A is 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 connec...

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 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 will ...
