Embodiment 1

[0039] Such as figure 1 As shown, a magnetorheological fluid recovery device based on centrifugal separation in this embodiment includes an outer barrel body 1 , an inner barrel body 2 , an adsorption tube 3 and a filter screen 4 . Wherein, the inner barrel body 2 is installed in the outer barrel body 1 through bearing rotation, specifically in this embodiment, the bottom of the inner barrel body 2 and the outer barrel body 1 are supported and connected by a thrust bearing 5, and the outer side wall of the inner barrel body 2 A lateral bearing is installed between the inner wall of the outer barrel body 1, the thrust bearing 5 supports the rotation of the inner barrel body 2, and the lateral bearing ensures the rotation stability of the inner barrel body 2, effectively reducing the damage caused by uneven force and vibration of the inner barrel body 2. The resulting vibration and noise of the whole machine also improves the structural strength of the whole machine. The inner ...

Embodiment 2

[0046] A magnetorheological fluid recovery device based on centrifugal separation in this embodiment is further optimized and improved on the basis of Embodiment 1. We know that during the rotation of the inner barrel body 2, the magnetic substance has a tendency to approach the filter screen 4 under the action of centrifugal force, so that under the action of the magnetic field force, the magnetic substance needs to overcome the centrifugal force and approach the adsorption tube 3, so it must be ensured that the magnetic substance is under the influence of centrifugal force. The magnetic field force is greater than the centrifugal force, so that the magnetic substance will not stick to the filter screen 4, but it is limited by the comprehensive factors such as the limitation of the magnetic field size, the small rotating speed, the ineffective separation of the magnetic substance and the carrier liquid, the magnetic saturation of the magnetic substance, and the processing effic...

Embodiment 3

[0048] This embodiment provides a method for recycling magnetorheological fluid. The magnetorheological fluid recovery device based on centrifugal separation in Example 2 is used to treat the magnetorheological fluid, and the diameter of the filter hole 201 is specifically limited to 2mm. The mesh number of net 4 is at 2400 mesh. The magnetorheological fluid to be treated is a magnetorheological fluid with oleic acid as the main component of the surfactant, the main dispersed particles are hydroxyl iron powder, the magnetic saturation is 2.5T, and the carrier liquid is dimethyl silicone oil; and in this embodiment The magnetorheological fluid waste to be treated is the solution after its use exceeds its shear fatigue life, and at this time, the variation of its zero-shear viscosity and adjustable multiple exceeds ±10% during the inspection process. The specific operation steps are as follows:

Abstract

The invention discloses a magnetorheological fluid recovery device and method based on a centrifugal separation effect, belonging to the field of magnetic waste liquid recovery equipment. The recovery device comprises an outer barrel, an inner barrel, an adsorption pipe and a filter net, wherein the inner barrel is installed in the outer barrel in a rotating manner by virtue of a bearing and is driven by a motor, and a filter hole communicating the inside and outside of the inner barrel is formed in the side wall of the inner barrel; the adsorption pipe is arranged in the middle of the inner barrel, and a coil is arranged in the adsorption pipe; the filter net is arranged on the inner side wall of the inner barrel and covers the filter hole; and the outer wall of the outer barrel is provided with a recovery check valve. The method utilizes the recovery device to allow carrier liquid and magnetic substances to make reverse motion under the dual effect of a centrifugal force and a magnetic field, so that the carrier liquid and the magnetic substances can be separated and recovered. By adopting the magnetorheological fluid recovery device and method, the magnetic substances of magnetorheological fluid can be separated and recovered from the carrier liquid. The magnetorheological fluid recovery device is simple in structure, easy to operate, high in recovery efficiency of the magnetic substances and also capable of reducing the subsequent treatment difficulty of the carrier liquid.

Description

technical field [0001] The invention belongs to the field of magnetic waste liquid recycling and processing equipment, and more specifically relates to a magnetorheological fluid recycling device based on centrifugal separation and a method thereof. Background technique [0002] Magnetorheological Fluid (MR fluid for short) is a controllable fluid, which is an emerging intelligent material. It is mainly composed of magnetic particles, carrier liquid and stabilizer. Suspension liquids with characteristic non-colloidal properties. Magnetorheological fluid can produce obvious magnetorheological effect under a magnetic field, and can realize rapid and reversible conversion between liquid and solid or semi-solid. During this process, the viscosity of magnetorheological fluid keeps changing continuously, and the entire conversion process is extremely fast. And controllable, has the characteristics of extremely small energy consumption, convenient preparation, wide temperature app...
