Cooling tank used for transferring potassium nitrate and provided with anti-blocking mechanism

The utility model discloses a cooling tank used for transferring potassium nitrate and provided with an anti-blocking mechanism, which relates to the field of potassium nitrate production and comprises a base, the top of the base is connected with a base supporting column, the top of the base supporting column is connected with a tank body, the top of the tank body is provided with a motor, and the bottom of the motor is connected with a rotating shaft. And the rotating shaft penetrates through the tank body and is provided with a scraper in the tank body. According to the potassium nitrate crystal cooling device, potassium nitrate crystals on the inner wall of the cooling tank are scraped into the discharging opening through the scraper, and then the potassium nitrate crystals accumulated at the discharging opening are conveyed out of the device under the action of the transmission threaded shaft, so that the phenomenon that the discharging amount of the discharging opening is small due to the fact that the
