Description

Technical Field

[0001] The utility model relates to the technical field of industrial wastewater processing, in particular to industrial wastewater softening equipment. Background Art

[0002] Industrial wastewater softening equipment is a kind of equipment used to treat industrial wastewater. Its main function is to remove hardness ions in wastewater, such as calcium and magnesium, to reduce the hardness of water. The following are some common industrial wastewater softening equipment; sodium ion exchanger: through sodium ion exchange resin, calcium and magnesium ions in water are exchanged with sodium ions in resin to achieve the purpose of softening water. This equipment is suitable for treating wastewater with high hardness, but it is necessary to regenerate the resin regularly; reverse osmosis equipment: using the semi-permeability of reverse osmosis membrane, the wastewater is filtered to remove salt and impurities in the water. The water quality of reverse osmosis equipment is high, but the equipment cost is relatively high; electrodialysis equipment: under the action of electric field, the ions in the water are migrated through the ion exchange membrane to achieve the purpose of softening water. Electrodialysis equipment is suitable for treating wastewater with high salt content, but the energy consumption is high; lime softening method: adding lime to wastewater, so that calcium and magnesium ions react with lime to form precipitates, thereby reducing the hardness of water. This method is simple and easy, but it will produce a lot of waste residue, which needs to be treated later. When choosing industrial wastewater softening equipment, you need to consider factors such as wastewater quality, treatment volume, and treatment cost, and choose the appropriate equipment according to the actual situation. At the same time, in order to ensure the normal operation and treatment effect of the equipment, it is also necessary to regularly maintain and service the equipment.

[0003] For example, the utility model with application number 201922254452.3 discloses a double alkali method high-density tank softening equipment for industrial wastewater, in which the second pulley is driven to rotate by the output end of the second driving motor, and the second pulley drives the first pulley to rotate through the belt, and the first pulley drives the conveyor belt to rotate through two rollers, so that the conveyor belt drives the scraper to move, and the sludge can be discharged from the sewage outlet into the separation area through the movement of the scraper, and the spiral blade is driven to rotate by the output end of the first driving motor, so that the spiral blade discharges the sludge scraped off by the scraper from the sewage pipe to the high-density tank. This device can discharge the sludge from the high-density tank in time, and can effectively improve the sewage treatment effect of the high-density tank.

[0004] Similar to the above application, there are still some shortcomings:

[0005] This type of industrial wastewater double-alkali high-density tank softening equipment mixes industrial wastewater with reactants and then uses a scraper to transport the sludge. However, when discharging the sludge, the water in the tank must be drained before the scraper can be operated to discharge the sludge into the separation area. Discharging the sludge during the reaction process will result in incomplete separation of water and solid, affecting the treatment of wastewater.

[0006] Therefore, an industrial wastewater softening equipment is designed to optimize the above problems. Utility Model Content

The use of a linkage mechanism to drive the stirring blades to rotate reduces production costs, thereby meeting different usage requirements. BRIEF DESCRIPTION OF THE DRAWINGS
