Problems solved by technology

[0003] At present, the commonly used centrifuges are separated and reassembled by the drive device (mainly the motor) and the solid-liquid separation device (mainly the liquid collection chamber and the driven centrifugal unit). Functions are the same) are mechanically fixed on the drive shaft, resulting in difficulties in the disassembly and assembly of the centrifugal drum and the cleaning verification of the centrifugal equipment, and the equipment is too complicated and heavy, the noise and vibration are too large, the manufacturing process is complicated, and the maintenance is inconvenient. However, it cannot fully meet the needs of the complete separation of solid-liquid mixtures in laboratory experiments and pilot experiments.

Embodiment 1

[0169] This embodiment is a rotating part of a fluid channel, which adopts figure 2 Rotor unit support with flow holes shown.

[0170] The integrally molded rotor unit support with guide flow holes (102) includes a cylindrical main body (101+107) carrying the rotor unit and a bottom part of the bottom of the semi-closed main body, in which the fluid passage rotates The bottom has: the mounting bracket fixing hole (201), the material-liquid distribution plate located in the center of the bottom, the annular boss A (203) located at the junction of the liquid collection chamber wall and the bottom, and the guide flow hole (102) on it And a positioning protrusion (204) located outside the wall of the liquid collection cavity that prevents the rotor unit from producing circumferential movement.

[0171] After the rotor unit is injection molded and magnetized, the surface facing the air gap is sprayed to form an electrical insulation layer, and then this component is fixed through...

Embodiment 2

[0173] This embodiment is a fluid channel rotating part, using the first metal part (1106) and the second metal part (1101) shown in Fig. 13 .

[0174] Such as Figure 13B As shown, the second metal component (1101) has a second connecting arm (1102) extending radially inward, an axial protrusion (1301) located at the end of the second connecting arm and a through hole located on the axial protrusion (1302); the first metal component (1106) has a first connecting arm (1104) extending radially outward and a through hole (1105) on the first connecting arm.

[0175] After inserting the axial protrusion (1301) at the end of the second connecting arm into the through hole (1105) on the first connecting arm (the two are not in contact), place it in the mold together with the rotor unit and after positioning (the rotor unit and the first connecting arm A metal part is not in contact), and injection molding is generally shown in Figure 6 as a fluid channel rotating part with a guide ...

Embodiment 3

[0177] This embodiment is a rotating part of a fluid channel, which adopts Figure 7-1 Shown is a first metal part with a guide through-hole structure, which has the entire bottom of the rotor unit support.

[0178] The integrally molded first metal part with a guide hole structure has: a conical boss (105) with a motor shaft mounting hole (104) located in the center of the first metal part, and a static part A of the fluid passage Corresponding to the annular concave cavity, the circular boss (701) with the center line of the motor shaft as the axis and the conduction holes (102) distributed at equal intervals along the circumferential direction on the circular boss are located at the first A card slot (702) on the edge of a metal component, a card-shaped protrusion forming the card slot, and a positioning hole (703) on the card-shaped protrusion.

[0179] After the rotor unit and the first metal part (the two are not in contact) are placed in the mold and positioned, inject...

Abstract

The present invention relates to a fluid channel and its solid-liquid separation device, which is characterized in that the solid-liquid separation device at least includes a fluid channel rotating part, a fluid channel static part, a driven centrifugal unit, a stator assembly and a rotating support unit, wherein an electrical insulation The fluid channel rotation part of the measure comprises a centrifuged liquid collection cavity, a rotor unit support and at least one rotor unit. The advantages of the present invention are: the solid-liquid centrifugal separation of the equipment and the collection and delivery of the liquid are integrated with the electrical insulation design of the motor rotor and / or stator, the equipment has high safety, and its manufacture, use and cleaning verification are very simple. Moreover, when the liquid flows out of the solid-liquid separation equipment, it will not be disturbed by centrifugal force, which can overcome various defects or disadvantages existing in the existing solid-liquid separation equipment.

Description

technical field [0001] The invention relates to a fluid channel and a direct-drive solid-liquid separation device thereof, and the solid-liquid separation device belongs to the field of centrifuges. Background technique [0002] In the research process of small laboratory test and pilot test, the most commonly used solid-liquid separation equipment is mainly the combination of Buchner funnel and suction filter bottle and centrifuges of various specifications, and the combination of Buchner funnel and suction filter bottle is only suitable for In laboratory research, in order to simulate the actual situation in production and provide necessary centrifuge operation data for production, centrifuges are more recommended. [0003] At present, the commonly used centrifuges are separated and reassembled by the drive device (mainly the motor) and the solid-liquid separation device (mainly the liquid collection chamber and the driven centrifugal unit). Functions are the same) are me...
