Chemical filtering device

Abstract

The invention discloses a chemical filtering device. The chemical filtering device comprises a filtering tank. The filtering tank is a three-layer structure and comprises a first filtering zone, a second filtering zone and a third filtering zone. A primary filter is arranged between the first filtering zone and the second filtering zone. A re-filter is arranged between the second filtering zone and the third filtering zone. A stirring device is arranged in the first filtering zone. The stirring device comprises multiple propellers. Each one of the propellers comprises multiple blades which can cut and crush particles in the waste liquid so that filter and material outlet blocking is preliminary prevented. Through combination of the primary filter and the re-filter, waste blocks or particles in the waste liquid are well separated from the water liquid and material outlet blocking caused by wastes in the waste liquid is effectively prevented. The chemical filtering device has very good use effects in waste water treatment in the chemical industry.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a filter device used in the chemical industry. Background technique [0002] In the chemical industry, many reactions are carried out in reactors, and the products after the reactions need to be treated, so a large amount of wastewater will be generated, which often contain lumps or particles of different sizes and particle sizes. If the wastewater reaches the standard, it is often treated with a filter device. The traditional filter device is a layer of filter screen or filter plate set in the filter bucket, the filtering effect is not good, and the outlet of the filter bucket and the filter screen or filter plate are often blocked. Leak holes not only significantly affect the filtering effect, but also need to frequently replace these water outlets and filter screens or filter plates, resulting in waste of enterprise costs. And the water that seeps through from filter screen o...

[0002] In the chemical industry, many reactions are carried out in reactors, and the products after the reactions need to be treated, so a large amount of wastewater will be generated, which often contain lumps or particles of different sizes and particle sizes. If the wastewater reaches the standard, it is often treated with a filter device. The traditional filter device is a layer of filter screen or filter plate set in the filter bucket, the filtering effect is not good, and the outlet of the filter bucket and the filter screen or filter plate are often blocked. Leakage holes not only significantly affect the filtering effect, but also need to replace these water outlets and filter screens or filter plates frequently, resulting in waste of enterprise costs

Moreover, the water permeated from the filter screen or filter plate often causes a violent impact on the water outlet, making the water outlet parts more easily damaged, which greatly affects the normal production of the chemical plant.
