Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of kilns, and in particular to a kiln cooling system. Background Art
[0002] In the field of battery powder manufacturing, the kiln is an important production equipment. After the material is sintered at high temperature in the kiln, a cooling zone needs to be set up at the tail of the kiln to cool the material and sagger to avoid damage to personnel and equipment.
[0003] Among traditional cooling technologies, water cooling is a relatively efficient cooling method. Conventional water cooling is to directly connect chilled water to the cooling zone pipe for heat exchange and cooling. Chilled water is produced by the chiller through refrigeration, and its temperature is 7℃-10℃. However, such low-temperature chilled water is not required to cool the kiln, so there is a waste of energy. In addition, too low chilled water temperature will also cause condensation in the kiln. If condensation drips into the material, it will cause quality accidents. In addition, the valves supporting chilled water are often manual ball valves. When the temperature in the kiln is too low, it cannot be accurately regulated, and the adjustment time is relatively long. Utility Model Content

When the temperature sensor 7 detects that the temperature is not within the set temperature range, the control unit 5 adjusts by controlling the chilled water in the first water storage tank 1 to achieve automatic temperature adjustment, reduce the work of on-site personnel, and avoid the problem of long adjustment time; a cooling tower 4 is used to cool the water after heat exchange, and heat is dissipated through the flow and evaporation of water, which greatly reduces the loss of power consumption. In the prior art, a chiller is used, and a compressor is required for cooling. The compressor has a large power of about 263kW;

The function of the spare pipe 15 is to directly transport water to the kiln cooling pipe 2 through the spare pipe 15 for cooling when the first water pump 9 is damaged for maintenance, so as to ensure the normal operation of the system.
