Abstract

The invention belongs to the technical field of chemical engineering filter devices, and particularly relates to a filter device for a chemical engineering experiment. Filter modules are arranged in atank body; the filter modules are provided with filter nets in sequence from top to bottom; the filter nets are mounted on electromagnetic locating blocks; liquid level sensors are used for recordingliquid level heights of filter layers and liquid discharging layers; ventilating holes are formed in the electromagnetic locating blocks; a pneumatic control module is connected with the ventilatingholes; when the liquid level sensors detect that the liquid level heights of the filter layers reach set values, a suction pump performs pulse inflation on the filter layers, and then extracts air from the filter layers till normal pressure or negative pressure is realized to achieve a forced filter effect on the filter layers. The filter device is mainly used for filtering viscous liquid for chemical engineering production and a chemical engineering experiment; meanwhile, the filter device is applicable to connection of different flange plates, is wide in application range, and brings great convenience to the chemical engineering production and the chemical engineering experiment.

Description

technical field [0001] The invention belongs to the technical field of chemical filter devices, in particular to a filter device used in chemical experiments. Background technique [0002] There are many kinds of chemical raw materials and their uses are very wide. There are as many as 5 to 7 million kinds of chemicals in the world, and more than 100,000 kinds have been sold and circulated in the market, and more than 1,000 new chemicals come out every year. In order to obtain relatively pure ingredients for so many chemicals, most of them need to be filtered with the help of filter devices. However, most of the existing filter devices have certain defects in the structure, poor filtering effect and low filtration efficiency, which seriously affect meet the large-scale production needs of the chemical industry. [0003] In the prior art, there are also some technical solutions for chemical engineering used for filtering devices. For example, a Chinese patent with applicatio...
