Unfortunately there's no way to do this. However in the location where your project is saved there should be a folder called: Adobe After Effects Auto-Save If you have a version of the project in there that saved before you deleted the animation and saved then you can open that and have your animation back (or at least maybe some of it). As soon as you open this project (if you find it) you should rename it and save it outside the auto-save folder.
For future reference when doing something like what you did, rather than deleting the animation and then saving. First save the project under a new name (like "animation version02") then make the new animation in that project. That way you'll have a separate project for each version of the animation.
By the way the settings for auto-save are under Preferences > Auto-Save. There you set the frequency and location of your auto saves.
