Description

Technical Field

[0001] The utility model relates to the technical field of sludge purification, and more specifically to a feeding device for adding calcium hypochlorite to sludge. Background Art

[0002] Calcium hypochlorite, commonly known as bleaching agent, is often used in the bleaching process of chemical production. It occupies an important position in industrial production due to its rapid onset and outstanding bleaching effect. Calcium hypochlorite is mainly used for bleaching of pulp in the papermaking industry and bleaching of cotton, linen and silk fiber fabrics in the textile industry. It is also used for sterilization and disinfection of urban and rural drinking water, swimming pool water, etc.; in the chemical industry, it is used for the purification of acetylene, the manufacture of chloroform and other organic chemical raw materials, and can be used as wool shrinkage-proof agent, deodorant, etc.

[0003] When existing calcium hypochlorite is used in sewage purification, workers are required to add calcium hypochlorite to the sewage to react with the sewage. However, each time the workers manually add calcium hypochlorite, they mostly add it in a certain area, so that the sewage in the purification tank does not react completely with the calcium hypochlorite, resulting in poor purification effect.

[0004] After searching, a Chinese patent with application number CN202221761009.0 discloses a calcium hypochlorite spraying device for sewage treatment. The utility model sprays evenly in all directions through a sprinkling opening, and the sprinkling rod rotates, driving the worm gear to rotate, causing the rotating rod to rotate, driving the moving gear to rotate, causing the moving gear to move left and right on the tooth plate, driving the moving plate to move left and right, causing the sprinkling rod to move left and right, and spraying calcium hypochlorite evenly in the purification tank, so that the sewage and calcium hypochlorite react more thoroughly, thereby improving the purification effect of the device.

[0005] However, when the above-mentioned spraying device is actually used, when calcium hypochlorite is added to the sludge, the calcium hypochlorite will be added to the surface of the sludge, and repeated stirring is required to mix the calcium hypochlorite and the sludge to a certain extent, which greatly affects the reaction efficiency of the calcium hypochlorite and the sludge.
