Microfiltration-ultrafiltration experimental device

This device is a small membrane filtration device for laboratory, which can be widely used in solution or gas material separation, concentration and purity (polymer, cells, microorganisms, viruses, water colloids, impurities, rust, bacteria, algae, etc. To. It uses a thin film with ability to separate the medium, and the membrane wall densely distributes micropores. Under a cert--n pressure, the raw solution is filtered by the side of the membrane, the solvent, and the small molecule of the small molecule, and the large molecular solution is cut off by the membrane, so as to achieve the purpose of material separation and concentration. The membrane separation process is the dynamic filtering process. The solution of the macromolecular solution is blocked by the membrane wall. As the concentrated liquid flows out of the membrane component, the membrane is not easily blocked and can be used continuously for a long time. The filtering process can be run at room temperature and low pressure, with no phase change and efficient energy saving.

1. Experimental device composition

The experimental device consists of the experimental workbench, the hydraulic pumping station, the commonly used hydraulic element, the electrical control unit, and the data collection system.

1. Experiment workbench

The experimental workbench is composed of experimental installation panels (aluminum alloy profiles) and experimental operation table. The installation panel is an aluminum alloy profile structure with the "T" groove. It can be convenient and freely installed with hydraulic components to match the experimental circuit.

2. Auxiliary platform structure

It is made of static spraying on the surface of the cold -rolled steel plate. The countertop has a "T" groove profile. It is convenient for experiments. The interior of the hydraulic circuit is divided into two parts of the structure. (The experiment is completed, and it is convenient to place the hydraulic element.) Half of the hydraulic components are the oil pipe stent, and the bottom has a steel oil filter mesh. There are four universal foot wheels at the bottom of the auxiliary platform for easy placement.

3. Common hydraulic components

Focusing on the domestically produced Lixiang series hydraulic valve components (Beijing Huade), please refer to the configuration list for det--ls;

Each hydraulic element is equipped with an oil circuit transition bottom plate, which can be convenient and freely placed on the experimental panel (aluminum alloy profile).

The oil circuit overlap adopts an open and closed fast -changing joint, which is convenient for disassembly and does not leak oil.
