Description

Novel centrifugal machine

Technical Field

The invention relates to the field of centrifuges, in particular to a tripodia type centrifuge.

Background

The three-leg centrifuge is named because the bottom support is three column feet which are arranged in an evenly-divided triangular mode. The three-leg centrifuge is a solid-liquid separation device, and is mainly used for separating and removing solids in liquid or separating out liquid in the solids. The three-leg centrifuge is the centrifuge with the most extensive application, is widely applied to various industries from the first centrifuge, is popular all over the world today, and has the advantages of low manufacturing cost, good shock resistance, simple structure and convenient operation.

When the existing centrifugal machine is used, filter bags with different meshes need to be replaced for materials with different particle sizes. The filter cloth is easy to block, the replacement and the cleaning are troublesome, and the cloth filter bag has the problem of damage, so that the material leakage is easy to cause. The rotary drum of the centrifugal machine is made of all stainless steel, so that the inertia is large due to the large mass of the rotary drum, and the time required for starting and stopping is long. Therefore, the quality of the rotary drum is reduced, and a better filtering material is provided, so that the use efficiency of the three-leg centrifuge is improved.

The plate-type titanium filter element is prepared by using industrial high-purity titanium powder (99.4%) as a raw material, performing screening and cold isostatic pressing, and then sintering at high temperature and high vacuum. It has the following components: uniform pore diameter (0.2-100 um), high porosity (28-50%), small filtration resistance, high permeation efficiency, high temperature resistance, acid and alkali corrosion resistance (pH 2-12), no particle shedding, easy cleaning, long service life (several times of that of a membrane filter element generally), no magnetism and no toxicity. Is very suitable for the fields of medicine industry, water treatment industry, food industry, biological engineering, chemical industry, petrochemical industry, metallurgical industry and gas purification.
