Mixing material separation and dust-reduction device and application thereof

Abstract

The invention discloses a mixing material separation and dust-reduction device and application scenarios thereof. The device comprises a multi-channel bionic swirler and an ejector, wherein the multi-channel bionic swirler comprises an overflow tube, a swirl chamber, a shrinking hopper and a sample discharge tube, which are fixedly connected with each other from top to bottom; bionic non-smooth units are distributed on the inner wall surface of the multi-channel bionic swirler; an inlet channel is disposed at the upper end of a side wall of the swirl chamber; the ejector comprises a spray nozzle, a mixing chamber, a throat tube and a diffusion chamber; one end of the spray nozzle is connected with a high-pressure pump, and the other end of the spray nozzle stretches into the interior of the mixing chamber; the mixing chamber is connected with the overflow tube in a closing manner; two ends of the throat tube are respectively connected with the mixing chamber and the diffusion chamber in a closing manner; and the diffusion chamber is connected with a dust-reduction box through a pipeline. The device is mainly used in scenarios in which a large amount of dust is generated such as drilling, geotechnical engineering, grouting engineering, geological disaster control engineering, mining, tunnel piercing and the like, and is capable of solving the technical problems that the existingdevice is low in separation efficiency on mixing materials, unsatisfactory in dust-reduction effect, serious in abrasion, short in service life and the like.

Description

technical field

[0001] The invention belongs to the technical field of mixed material and dust reduction treatment equipment, and in particular relates to a mixed material separation and dust reduction device. Background technique

[0002] The cyclone (Swirler) is a common sample separation device, and its working principle is mainly based on centrifugal sedimentation and the density difference between different materials. In petroleum engineering, the cyclone mainly includes a cyclone desander and a cyclone desilter, which are used to remove solid phases such as sand and mud mixed into the drilling fluid during oil drilling, so as to ensure the normal rheological properties of the drilling fluid ; In the construction of geotechnical engineering, such as the stabilizing liquid that needs to be used during the construction of the underground diaphragm wall, the waste liquid generated after the construction cannot be discharged directly, but the waste liquid needs to be treate...
