Problems solved by technology

Adding liquid pipetting tools (such as droppers, pipettes, etc.) will disturb or destroy the precipitation interface when improperly operated, and will also increase the risk of sample contamination, and the extensive use of disposable droppers and drippers will also affect the quality of the sample. The environment brings pollution

Embodiment 1

[0020] like Figures 1 to 3 As shown, a micro-pressure differential precipitation separation device includes a settling tube assembly and a settling tube holder. The settling set includes a settling tube 1, a manifold 2 and a dripper 3. Above the settling tube 1 is a One end of the manifold 2 communicates with the side of the sedimentation pipe 1, and the other end connects with the dripper 3. Manifold 2 is a bent pipe drawn from the side wall of sedimentation pipe 1. The angle ∠A between manifold 2 and sedimentation pipe 1 is 60°. Manifold 2 has a bend. The angle at this bend ∠B=∠ a. The diameter of the manifold 2 is smaller than that of the settling pipe 1; the diameter of the dripper 3 is smaller than that of the manifold 2. The connection between the manifold 2 and the settling pipe 1 is located at 1 / 5 of the bottom of the settling pipe 1 upward. When the settling tube 1 is placed vertically, the intersection point of the manifold 2 and the settling tube 1 is on the sam...

Embodiment 2

[0028] The included angle ∠A between the manifold 2 and the sedimentation pipe 1 is 30°, and the connection between the manifold 2 and the sedimentation pipe 1 is located at 1 / 2 of the bottom of the sedimentation pipe 1. All the other are with embodiment 1.

Description

technical field [0001] The invention relates to a separation device, in particular to a micro-pressure differential sedimentation separation device. Background technique [0002] Solid-liquid separation is one of the most common operations in chemical, chemical, pharmaceutical, metallurgy, environmental protection and other industries. It is an important part of heterogeneous phase separation. In many experimental operations and production units, filtration and separation devices are the most important factors that affect the experimental results. and an important part of product quality. According to literature, the current solid-liquid separation process can be divided into sedimentation separation and filtration separation, among which sedimentation separation can be divided into gravity sedimentation, centrifugal force sedimentation and electromagnetic force sedimentation according to the driving force; filtration separation can be divided into gravity filtration, vacuum...
