This machine is a four-stage treatment with circulating cold water cooling. The first section of the equipment uses hot water to spray the thermos bottle at a temperature of 74 ℃ for 4-5min. The second and third sections of the cooling tower use circulating water and tap water for spray cooling. The fourth section uses pure water to wash the bottle body to prevent stains on the bottle body. The equipment is equipped with an automatic chlorination pump, which can adjust the chlorination amount according to the water replenishment amount.
The design inlet temperature is 65 ℃, and the outlet temperature is lower than 40 ℃. The machine is composed of four parts: running chain plate, machine body, water circulation pipeline system and electrical control system. The frequency conversion motor drives the driving square shaft to rotate through the cycloid pin wheel reducer, and the sprocket on the square shaft drives the plastic chain plate to move, forming the chain plate mechanism. As long as the cooled material bottle (tank) enters the plastic chain plate, it will be pulled into the first cooling section by the chain plate, and it will be automatically crowded and arranged in order. The atomizing nozzle is arranged orderly on the top of the cooling area by the spray pump 1 The water is supplied to the thermos bottle, the bottle (tank) is heated, and the cooled water flows into the lower water tank, which is sent to the cooling device by the circulating pump for cooling, for the circulating use of the second and third cooling areas. After spraying, the pure water flows into the downcomer, so the fourth section of cooling water does not need to enter the cooling device. The fourth tank is self circulation. When the tank is full, the water will flow into the third and second tanks.
The fourth section is pure water spray device, which aims to make the cooled bottle (tank) dry without water mark. The cooling tunnel chain plate is a product of Rexnord company in the United States. The speed of conveyor belt is regulated by frequency converter. All spray pipes and nozzle heads are made of stainless steel, and each nozzle sprays water evenly. The water collecting tank of the cooling tunnel is made of stainless steel, and is equipped with high and low liquid level control and alarm functions. The spray cooling tunnel is equipped with spray circulating water pump and dosing pump.
