Method and apparatus for loading and conditioning materials
View Patent ↗A method and apparatus for optimally loading and conditioning materials for transport is provided. Specially, the invention, in a preferred embodiment, relates to loading ash-like materials which require treatment prior to loading onto a truck or vehicle to avoid slurry spillage, overload or airborne particulate during loading or transport. The system conditions the ash-like materials by liquid additions proportional to material flow rate, truck information, slump height and/or slump weight. The system further includes a slump height or weight indicator and a communication and integration system.
1. A method of loading and conditioning a material during loading comprising the steps of:
adding liquid material and dry material as the loading begins;
sensing speed and slump progression through the use of a radar detector;
calculating a mix shift level based on the speed and the slump progression; and
restricting flow of the dry material as the loading reaches a target weight to form a gradient of liquid concentration to be loaded across each slump with respect to slump height.
2. The method of claim 1 , wherein the sensing is accomplished by means of a radar detector.
3. The method of claim 2 , wherein the radar detector senses slump weight and reaches the mix shift level and the loading continues with liquid added to a regular mix proportion.
4. The method of claim 1 , wherein the material is an ash-like material.
5. The method of claim 1 , further comprising a step of mounting a dry flow measuring device in line with a vertical drop of the material below a material control valve, and dynamically controlling liquid density of the material to suppress dust and prevent formation of slurry.
6. The method of claim 1 , further comprising a step of adding a wet blanket of the material on top of each the slump to allow a bottom of each the slump to be initially drier, to prevent the material from becoming airborne during transport and to prevent slurry formation.
7. The method of claim 1 , further comprising a step of indicating to a driver a percentage of slump height during the loading.
