Abstract
Description
Technical Field
[0001] This utility model relates to a rinsing device for iron oxide pigments. Background Technology
[0002] Iron oxide pigments are produced using ferrous sulfate, iron filings, and liquid alkali as main raw materials through a wet sulfate oxidation process. The entire oxidation process involves a three-phase reaction of gas, liquid, and solid. After the oxidation reaction, the iron oxide pigment needs to be filtered to remove large particles. The iron oxide pigment solution is then sent to a membrane filter for rinsing, which requires a large amount of clean water. Currently, the rinsed water is directly discharged into the subsequent wastewater treatment system, resulting in a significant waste of water resources and placing enormous pressure on the wastewater treatment system. Utility Model Content
[0003] To address the aforementioned problems, this invention provides a rinsing device for iron oxide pigments, effectively solving the issues mentioned in the background art.
[0004] The technical solution adopted in this utility model is:
[0005] A rinsing device for iron oxide pigment includes a diaphragm filter. The feed pipe of the diaphragm filter is connected to a pigment feed pipe and a rinsing pipe. The pigment feed pipe is equipped with a feed pump and a feed valve. The other end of the rinsing pipe relative to the feed pipe is connected to a clean water pipe and a circulating water pipe. The clean water pipe is equipped with a clean water valve, and the circulating water pipe is equipped with a circulating valve. The drain pipe of the diaphragm filter is connected to a circulating water tank. The circulating water tank is equipped with a circulating water pump, and the outlet of the circulating water pump is connected to the circulating water pipe.
[0006] Preferably, the feed pipe is equipped with a booster pump.
[0007] If the flow rate in the feed pipe is insufficient during use, the booster pump can be turned on to increase the flow rate. The booster pump is installed on the feed pipe and can be used to boost the pressure of pigments, circulating water and clean water at the same time.
[0008] Preferably, the circulating water in the circulating water pipe is used for the initial rinsing of the diaphragm filter, and the clean water in the clean water pipe is used for the final rinsing of the diaphragm filter.
[0009] The circulating water is used for the initial rinsing of the diaphragm filter, while the clean water is used for the final rinsing. Since the final rinsing is done with clean water, the rinsing quality is guaranteed, and the circulating water is only used for the initial rinsing, so it does not reduce the rinsing quality.
[0010] This invention connects a clean water pipe and a circulating water pipe in parallel on the rinsing pipe. The circulating water pipe is used to reuse the wastewater discharged from the diaphragm filter for rinsing the diaphragm filter. This improves water utilization and reduces the pressure on the subsequent wastewater treatment system while ensuring rinsing quality. Attached Figure Description
