Description

Technical Field

[0001] The present invention relates to a liquid distributor, and particularly to a solid-liquid mixture liquid distributor. Background Art

[0002] Traditional liquid separation devices often use static sieves or centrifugal separation structures, but there are obvious defects when dealing with mixtures containing solid particles. After long-term use, the static liquid distributor is prone to pipeline blockage due to solid deposition and requires frequent shutdown for cleaning, affecting efficiency; although centrifugal devices can separate solids and liquids, they have complex structures and high energy consumption, and it is difficult to achieve uniform liquid distribution at multiple outlets. Existing technologies generally lack the function of solid crushing, and the uncrushed particles are likely to cause blockage of subsequent pipelines and poor liquid separation stability. In addition, when distributing liquid at multiple outlets, due to uneven pressure distribution, there is often a problem of large flow deviation at some outlets. Although there are some improvement schemes (such as multi-stage shunting or configuring stirring components), there are still shortcomings such as loose structures and inability to balance slag crushing and pressure equalization. Therefore, there is an urgent need for a liquid distributor that can actively crush solids, balance 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 the existing technology. Summary of the Invention

[0003] To achieve the above object, the present invention provides a solid-liquid mixture liquid distributor, including: a stator outer tube, with multiple rows of liquid outlet tubes distributed along the length direction of its tube body, and each row of liquid outlet tubes is circumferentially spaced on the stator outer tube;

[0004] a rotor inner tube, coaxially sleeved inside the stator outer tube, with multiple rows of openings distributed along the length direction of its tube body, and each row of openings is circumferentially spaced on the rotor inner tube; an outer convex cutting edge is provided outside the openings of the rotor inner tube, and an inner concave fin is provided inside; a driving mechanism for driving the rotor inner tube to rotate relative to the stator outer tube.

[0005] Further, the cutting edge is in a spiral or serrated structure for chopping solid particles flowing through the openings.

[0006] Further, the fin extends axially from the inside of the opening towards the rotor inner tube, for accelerating the axial flow and pressure equalization of the solid-liquid mixture.

[0007] Further, the liquid outlet tubes of the stator outer tube and the openings of the rotor inner tube are correspondingly distributed axially and / or circumferentially.

[0008] Further, the driving mechanism includes a motor, and the motor is connected to the rotor inner tube.

[0009] Further, the rotation direction of the rotor inner tube is adapted to the inclination direction of the fin to form a pressure difference to promote the flow of the solid-liquid mixture.

[0010] Technical Effects

[0011] 1. More compact structure: The stator and rotor are coaxially sleeved, integrating the liquid separation and slag crushing functions, eliminating independent components and reducing the volume. 2. Anti-blocking and integrated liquid separation: The cutting edge at the opening of the rotor directly crushes solids, avoiding particle blockage at the outlet and reducing the dependence on additional crushing equipment. 3. More uniform liquid separation: Multiple discharge pipes cooperate with the openings and the rotation of the rotor to stir the mixed liquid, equalize the pressure, and ensure stable flow at multiple outlets. 4. Self-cleaning ability: The continuous rotation of the rotor drives the cutting edge to automatically clean the residues at the orifice, reducing the frequency of shutdown for maintenance.

[0018] The following introduces multiple preferred embodiments of the present invention with reference to the accompanying drawings of the specification to make its technical content clearer and easier to understand. The present invention can be embodied in many different forms of embodiments, and the protection scope of the present invention is not limited to the embodiments mentioned in the text.

[0019] In the accompanying drawings, components with the same structure are denoted by the same reference numerals, and components with similar structures or functions are denoted by similar reference numerals. The size and thickness of each component shown in the drawings are arbitrarily shown, and the present invention does not limit the size and thickness of each component. For the sake of clarity of the illustration, the thickness of some components in the drawings is appropriately exaggerated.

[0020] As Figure 1-2As shown in the figure, the solid-liquid mixture dispenser according to the present invention 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. A plurality of rows of tube groups are arranged in the longitudinal direction of the body of the stator outer tube 1, and each row of hole groups includes a plurality of liquid outlet tubes 11 arranged circumferentially on the stator outer tube 1. A plurality of rows of hole groups are arranged in the longitudinal direction of the body of the rotor inner tube 2, and each row of hole groups includes a plurality of openings 21 arranged circumferentially on the rotor inner tube 2.

[0021] See also Figure 3 and 4 , outside each opening 21 of the rotor inner tube 2, there is a convex cutting edge 22 provided, and at the same time, inside each opening 21 of the rotor inner tube 2, there is a concave fin 23 provided.

[0022] See also, for example, Figure 5 , during operation, the solid-liquid mixture flows in through the inlet 4 connected to the stator outer tube 1 through the flanges 41 and 12. At this time, the rotor inner tube 2 rotates under the drive of the motor 3. The fins 23 of the rotor inner tube 2 can accelerate the conveyance of the solid-liquid mixture in the tube towards the openings 21, and at the same time, can also agitate the liquid in the tube to make the pressure at all positions inside it uniform. According to the arrangement of the openings 21, the fins 23 can be set at different angles to deflect the liquid to different directions, so that the liquid forms a more sufficient disturbance inside the cavity, and the liquid pressure inside the cavity tends to be balanced. The solid-liquid mixture flowing out of the openings 21 enters the sandwich layer between the stator outer tube 1 and the rotor inner tube 2, and the solids in the solid-liquid mixture are shredded by the cutting edges 22 on the rotor inner tube 2, and then discharged through the liquid outlet tubes 11 on the stator outer tube 1. The design of a plurality of openings and liquid outlet tubes can make the outlet discharge the liquid intermittently in a cycle, so that the liquid discharged from each liquid outlet tube finally tends to be balanced.

[0023] The dispenser of the present invention has a more compact structure and has the function of shredding solids, and can evenly distribute the liquid transported in from the inlet to a plurality of outlets.

The form of the blades is not limited to the form described in the embodiments, and the open-type and multi-blade agitation methods similar to those described in the embodiments can achieve the same technical effects. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field according to the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
