Description

Technical Field

[0001] The utility model belongs to the technical field of ferrous sulfate heptahydrate production, in particular to a filtering device for ferrous sulfate heptahydrate production. Background Art

[0002] Ferrous sulfate heptahydrate, commonly known as green vitriol, is a common inorganic compound that appears as blue-green monoclinic crystals or particles and is odorless. It is widely used in water treatment, agriculture, medicine and industry. Ferrous sulfate heptahydrate is widely used in wastewater, sewage or sludge treatment, mainly based on its chemical properties such as flocculation and oxidation-reduction. It can make harmful chemicals harmless or reduce their harm by producing chemical changes in substances. In the production reaction of ferrous sulfate heptahydrate, there may be unreacted solid raw materials remaining. For example, when ferrous sulfate heptahydrate is prepared by reacting iron filings with sulfuric acid, there may still be unreacted iron filings after the reaction. Filtration can separate these solids from the post-reaction solution, so that the subsequent ferrous sulfate heptahydrate crystals are purer.

[0003] For example, the Chinese utility model provides a "filter device for the production of ferrous sulfate" with patent number: 202121271184.7, which includes a device body and an adjustment mechanism. The adjustment mechanism includes a mounting plate, a filter barrel is provided on the lower surface of the mounting plate, and two fixing columns are provided on the upper surface of the filter barrel. The inner cavity of the filter barrel is provided with a filter device. The electric telescopic rod is extended to drive the adjustment mechanism to rise and move out of the inner cavity of the device body. The filter device can be removed from the adjustment mechanism by adjusting the adjustment mechanism, and the filter device can be cleaned;

[0004] Although the above document solves the problem that the existing filtration device for ferrous sulfate production generally installs the filter layer inside the filtration device, which makes it inconvenient to clean the filter, there is still a disadvantage that the filter cleaning is not convenient enough. When cleaning the filter, the above patent needs to stop the machine and take out the filter through the driving mechanism for cleaning. Not only is the cleaning process troublesome, but it also affects the normal filtration efficiency. For this reason, we provide a filtration device for ferrous sulfate heptahydrate production to solve the above problems. Utility Model Content
