Description

technical field [0001] The invention relates to the field of machine tool cooling systems and workshop temperature regulation, and more specifically relates to an intelligent low-temperature gas cooling safety monitoring temperature regulation circulation system. Background technique [0002] At present, most of the machining equipment in the prior art uses coolant for cooling during the processing process, which has the disadvantages of polluting water resources and air; or uses low-temperature gas instead of coolant, but there is a greater safety hazard in the use of low-temperature gas. Hidden danger. At the same time, due to the principle of thermal expansion and cold contraction, in order to ensure the accuracy of processing, it is usually necessary to ensure a constant temperature in the processing workshop. Based on the cooling liquid and low-temperature gas and the need to ensure the temperature of the processing workshop, the following defects exist in the existing...

AI Technical Summary

Problems solved by technology

[0003] 1. The use of low-temperature gas for cooling in the prior art has great potential safety hazards. If the low-temperature gas is used improperly, it will cause frostbite to the processing equipment operator and the frostbite is irreversible;

[0004] 2. Cool the low-temperature gas in a closed space. Since the low-temperature gas will expand more than 20 times when it becomes normal temperature, the oxygen content in the space will be reduced. If the oxygen content is lower than 18%, the operator in the space will feel uncomfortable. , further discharge of low-temperature gas will cause suffocation hazard;

[0005] 3. At present, the cooling of low-temperature gas is limited to cooling when processing workpieces. For the spindle of processing equipment, traditional oil coolers or compressed air are cooled by refrigeration equipment to form cold air for cooling;

[0006] 4. When the temperature in the processing workshop is high, it needs to cool down, and a large central air conditioner will be used, which requires a lot of electric energy, resulting in a waste of energy

[0007] The above defects will cause major safety accidents, environmental pollution, or large-scale use of energy will also cause environmental pollution, which is contrary to the policy of protecting the environment and saving energy, making mechanical processing and manufacturing not green and environmentally friendly.
