Problems solved by technology

[0003] However, the centrifuges commonly used at present are all separated and reassembled by the drive device (mainly the motor) and the solid-liquid separation device (mainly the liquid collection chamber and the centrifugal drum). Too complex and bulky, too much noise and vibration, too high energy consumption, complex manufacturing process, inconvenient maintenance, difficult equipment cleaning verification and other defects or disadvantages, cannot fully meet the requirements of solid-liquid in laboratory tests and pilot tests. The need for thorough separation of the mixture

Embodiment 1

[0065] This embodiment is a motor stator with a static part of the fluid channel, and the attached Figure 4 The static part of the fluid channel.

[0066] The integrally molded fluid channel stationary part includes: a cylindrical motor housing (409) and a yoke positioning protrusion (401) located inside the housing for positioning the stator unit; an outer ring (404) and the inner ring (406) form a bottomed annular cavity, the annular cavity and the pipeline (405) at the bottom of the annular cavity constitute the static part (407) of the fluid channel; the inner ring of the annular cavity is a bearing chamber The motor shaft mounting hole (408), the outer ring of the annular cavity extending outwards for connecting the motor casing has a ventilation hole (403) and a positioning through hole (402).

[0067] Insert the stator unit into the motor casing, and the injection-molded motor stator with fluid channel static part is roughly as attached Figure 5 As shown, the top ha...

Embodiment 2

[0069] This embodiment is a motor stator with a static part of the fluid channel, and the attached Figure 8 The static part of the fluid channel.

[0070] The integrally molded fluid channel static part includes: a bottomed annular cavity formed by an outer ring and an inner ring, and a fluid channel static part ( 407); the inner side of the inner ring of the annular cavity is a motor shaft mounting hole (408) with a bearing chamber, and the outer ring of the annular cavity extends outwards to fix the electronic unit with ventilation holes (403) and stator unit positioning holes (801 ).

[0071] After the stator unit is fixed in the positioning hole (801) of the stator unit by fixing screws or other methods, the injection molded motor stator with a static part of the fluid channel is roughly as attached Figure 5 As shown, the top has a liquid blocking boss (503) to prevent liquid from flowing in, and the bottom has a base (501) to increase the contact surface.

Embodiment 3

[0073] This embodiment is a motor rotor with a fluid channel rotating part, using the attached figure 1 , 2 , 3 fluid channel rotating part.

[0074] The integrally molded fluid channel rotating part includes: a guide ring surrounded by an outer ring (201) and an inner ring (202); a circular spacer plate ( 110), the center of the circular spacer plate is a conical boss (107) with a motor shaft mounting hole (106), and at least one circle with the motor shaft as the centerline includes an inner edge through hole (105) and an outer edge through hole The liquid outflow channel of (104) is positioned on the circular spacer plate between the conical boss (107) and the bottom of the liquid collection cavity inner wall (102); The radius of the edge is greater than the radius of the outer edge of the liquid blocking boss (503) on the top of the motor stator to prevent liquid from flowing in, and the end surface (103) has a positioning hole (101). The outer wall (109) of the liquid...

Abstract

The invention relates to a fluid channel, a motor with the same and a solid-liquid separation system with the motor. The fluid channel is characterized in that the fluid channel at least comprises a rotary portion and a static portion, the rotary portion at least comprises a liquid collection cavity, a flow guide ring, a spacer plate and at least one circle of through holes which have different functions, are connected with each other and take a motor shaft as a central shaft, the static portion comprises an annular cavity and a pipeline, liquid flows to a collection bottle through the pipeline, and an upper opening of the static portion is hermetically connected with a lower opening of the flow guide ring of the rotary portion. The system has the advantages that the liquid more smoothly flows out of the pipelines of the solid-liquid separation system without interference of centrifugal force, the system integrally designs liquid collection and transportation after solid-liquid separation, a motor rotor and a stator, manufacture and assembly technology is simplified, various defects or disadvantages of existing various solid-liquid separation devices can be overcome, manufacture and maintenance are facilitated, energy is saved, consumption is reduced, and cleaning validation is easily realized.

Description

technical field [0001] The invention relates to a fluid passage, a motor with the fluid passage and a solid-liquid separation system with the motor. The solid-liquid separation system belongs to the field of centrifuges. Background technique [0002] In the research process of laboratory small test and pilot test, the most commonly used solid-liquid separation equipment is mainly a combination of centrifuges of various specifications or a Buchner funnel plus a suction filter bottle, and the combination of a Buchner funnel plus a suction filter bottle is used in small It is more commonly used in experimental research. In order to simulate the actual situation in production and provide necessary centrifuge operation data for production, centrifuges are more recommended. [0003] However, the centrifuges commonly used at present are all separated and reassembled by the drive device (mainly the motor) and the solid-liquid separation device (mainly the liquid collection chamber...
