Welcome to AAC!
Unless this is for educational purposes it will almost certainly be preferable and a lot cheaper to buy a ready-made module.

 

Yes, I know I need a k type thermocouple, amplifier, mircoconntor and display.

You need to show us your initial design.

 

I Seriously suggest that you have a look at this chip:
