Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a centrifugal dehydration device for waste liquid containing calcium hypochlorite. Background Art

[0002] Calcium hypochlorite is an inorganic compound, commonly known as chlorinated lime, bleaching powder or bleaching essence. Calcium hypochlorite is a strong oxidant. It can generate heat and spontaneous combustion when mixed with organic matter and flammable liquids. It can explode when exposed to high heat. When exposed to air, it easily absorbs water and carbon dioxide and decomposes to release hypochlorous acid and chlorine. Hypochlorous acid then decomposes to produce hydrogen chloride and nascent oxygen. The nascent oxygen has a strong oxidizing power and has the ability to destroy pigment clusters, causing colored substances to fade and achieve a bleaching effect. Waste liquid containing calcium hypochlorite mainly comes from the process of using calcium hypochlorite as a bleaching agent, disinfectant or industrial raw material. This waste liquid has certain chemical properties and potential environmental risks, so it needs to be properly handled.

[0003] After searching, the Chinese patent with application number CN202320017360.7 discloses a centrifugal dehydration device. In view of the fact that during the production of calcium formate, the solid mixture needs to be evenly fed into the centrifuge to separate the mother liquor and the crystals, the crystals will fall off simultaneously while the mother liquor is thrown out. Once the crystals adhere to the water outlet at the bottom under the action of gravity, it will affect the dehydration efficiency of the device over time and there are defects. Therefore, in the process of using the centrifugal dehydration equipment body, in order to avoid the crystals sticking to the water outlet at the bottom of the dehydration barrel during the dehydration of calcium formate, a cleaning structure can be installed to avoid the crystals from clogging the bottom of the dehydration barrel. The rubber nails at the top of the cleaning structure can guide the floating medium in the dehydration barrel inside the dehydration barrel, and the adjustment structure can adjust the angle of the arc plate. Therefore, it is convenient to disassemble the cleaning structure, so as to clean it for the next use.

[0004] The centrifugal dehydration device is convenient for cleaning the bottom of the dehydration barrel during use. However, when the existing dehydration device is used to dehydrate the waste liquid containing calcium hypochlorite, the waste liquid contains a lot of impurities and particulate matter, and the impurities in the dehydrated waste liquid are easy to adhere to the inner wall of the centrifugal barrel. Since the barrel wall is deep, it is difficult for the staff to clean out the impurities, and manual scraping is required, which makes the cleaning process more difficult and troublesome, reduces the efficiency of cleaning the impurity particles, and thus delays the next use of the dehydration device.
