Description

Technical Field

[0001] This utility model relates to a liquid separator, and more particularly to a liquid separator for solid-liquid mixtures. Background Technology

[0002] Traditional liquid separators often employ static screens or centrifugal separation structures, but these have significant drawbacks when handling mixtures containing solid particles. Static separators are prone to pipe blockage due to solid deposition after prolonged use, requiring frequent shutdowns for cleaning and impacting efficiency. While centrifugal devices can separate solids and liquids, their complex structure, high energy consumption, and difficulty in achieving uniform liquid distribution across multiple outlets are problematic. Existing technologies generally lack solid crushing capabilities; insufficiently crushed particles easily cause blockages in subsequent pipelines, resulting in poor liquid distribution stability. Furthermore, uneven pressure distribution in multi-outlet liquid separation can lead to significant flow deviations at some outlets. Although some improvements have been made (such as multi-stage flow division or the inclusion of stirring components), they still suffer from structural weaknesses and an inability to simultaneously address both solid crushing and pressure equalization. Therefore, there is an urgent need for a liquid separator that can actively crush solids, equalize liquid distribution pressure, and has a compact structure to solve the pain points of high blockage risk, high energy consumption, and uneven liquid distribution in existing technologies. Utility Model Content

[0003] To achieve the above objectives, this utility model provides a solid-liquid mixture separator, comprising: a stator outer tube with multiple discharge pipes distributed along its length, each discharge pipe being spaced apart circumferentially on the stator outer tube; a rotor inner tube coaxially sleeved within the stator outer tube, with multiple rows of openings distributed along its length, each row of openings being spaced apart circumferentially on the rotor inner tube; the rotor inner tube having protruding cutting edges on the outer side of the openings and concave fins on the inner side; and a driving mechanism for driving the rotor inner tube to rotate relative to the stator outer tube.

[0004] Furthermore, the cutting blade has a spiral or serrated structure, used to cut solid particles flowing through the opening.

[0005] Furthermore, the fins extend axially from the inside of the opening toward the inner tube of the rotor to accelerate the axial flow and pressure equalization of the solid-liquid mixture.

[0006] Furthermore, the liquid outlet pipe of the stator outer tube and the opening of the rotor inner tube are distributed correspondingly in the axial and / or circumferential directions.

[0007] Furthermore, the drive mechanism includes a motor, which is connected to the inner tube of the rotor.

[0008] Furthermore, the rotation direction of the inner tube of the rotor is adapted to the tilt direction of the fins to create a pressure difference that promotes the flow of the solid-liquid mixture.

[0009] Technical effect

[0010] 1. More compact structure: The stator and rotor adopt a coaxial sleeve design, integrating liquid separation and slag crushing functions, eliminating separate components and reducing size. 2. Integrated anti-clogging liquid separation: The cutting edge at the rotor opening directly crushes solids, preventing particles from clogging the outlet and reducing reliance on additional crushing equipment. 3. More uniform liquid separation: Multiple discharge pipes and openings work in conjunction with rotor rotation to agitate the mixture, ensuring even pressure and stable flow from multiple outlets. 4. Self-cleaning capability: The continuous rotation of the rotor drives the cutting edge, automatically cleaning residue from the opening and reducing downtime for maintenance.

[0011] The following will further explain the concept, specific structure and technical effects of this utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of this utility model. Attached Figure Description

[0017] The following description, with reference to the accompanying drawings, illustrates several preferred embodiments of the present invention to make its technical content clearer and easier to understand. The present invention can be embodied in many different forms, and the scope of protection of the present invention is not limited to the embodiments mentioned herein.

[0018] In the accompanying drawings, components with the same structure are indicated by the same numerical designation, and components with similar structures or functions are indicated by similar numerical designations. The dimensions and thicknesses of each component shown in the drawings are arbitrary, and this invention does not limit the dimensions and thicknesses of each component. To make the illustrations clearer, the thickness of some components has been appropriately exaggerated in the drawings.

[0019] like Figure 1-2As shown, the solid-liquid mixture separator according to this utility model includes a stator outer tube 1 and a rotor inner tube 2. The stator outer tube 1 is sleeved outside the rotor inner tube 2. Multiple rows of tube groups are arranged along the length of the stator outer tube 1, and each row of holes includes multiple outlet tubes 11 arranged in the circumferential direction of the stator outer tube 1. Multiple rows of holes are arranged along the length of the rotor inner tube 2, and each row of holes includes multiple openings 21 arranged in the circumferential direction of the rotor inner tube 2.

[0020] See also Figure 3 and 4 A protruding cutting blade 22 is provided on the outside of each opening 21 of the rotor inner tube 2, while a concave fin 23 is provided on the inside of each opening 21 of the rotor inner tube 2.

[0021] See also: Figure 5 During operation, the solid-liquid mixture flows in through inlet 4, which is connected to the stator outer tube 1 via flanges 41 and 12. Meanwhile, the rotor inner tube 2 rotates under the drive of the motor 3. The fins 23 of the rotor inner tube 2 accelerate the transport of the solid-liquid mixture towards the opening 21, while also agitating the liquid within the tube to ensure uniform pressure throughout. Depending on the arrangement of the opening 21, the fins 23 can be set at different angles to guide the liquid in different directions, creating more thorough turbulence within the cavity and stabilizing the liquid pressure. The solid-liquid mixture flowing out of the opening 21 enters the interlayer between the stator outer tube 1 and the rotor inner tube 2, where it is shredded by the cutting blades 22 on the rotor inner tube 2, and then discharged through the drain pipe 11 on the stator outer tube 1. The design of multiple openings and drain pipes allows for intermittent cyclic discharge of liquid from the outlet, ultimately ensuring a more uniform discharge from each drain pipe.

[0022] The liquid dispenser of this invention has a more compact structure and a function of chopping solids, which can evenly distribute the liquid delivered from the inlet to multiple outlets.

[0023] The preferred embodiments of this utility model have been described in detail above. The blade form is not limited to that described in the embodiments; similar open-type, multi-blade agitation methods can achieve the same technical effect. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
