Sludge purification treatment device for preparing ceramsite

The sludge purification treatment device comprises a sludge treatment box and a U-shaped fixing frame, the U-shaped fixing frame is installed and connected to the top end of the sludge treatment box, in the sludge purification treatment device, when the sludge purification treatment device is used, impurities in sludge can be filtered through a filtering assembly structure, so that the impurities in the sludge can be filtered out conveniently when the ceramsite is prepared subsequently; the ceramsite quality can be improved, a first positioning rod is held by hand, a fixing frame is inserted into an opening in the side edge of the sludge treatment box, and the first positioning rod is inserted and fixed into a positioning hole in the side edge of the sludge treatment box, so that falling during use is prevented, and during use, through a filter screen plate on the inner side of the fixing frame, the ceramsite quality is improved. According to the device, impurities such as branches and garbage bags doped in s
