Abstract

A melter, mixer and applicator system for applying coating or sealing compositions is disclosed. An internal combustion engine, such as a diesel engine, is used to provide the motive force necessary to operate many or all of the components of the system. A tank surrounded by an internal heating system is provided for melting a first material, such as asphalt. An insulated cabinet is provided and heated from heat generated by the internal heating system. The plumbing configuration for the system is disposed within the heated cabinet for mixing the material heated within the tank with an additional material fed to the plumbing configuration by a proportioner pump. The output of this mixture serves, through a heated hose, as one of the inputs to the applicator, which is preferably a plural component spray gun. The other input to the applicator is another material fed directly from the proportioner pump. The proportioner, preferably provides the two materials running through it in a predetermined ratio amount with respect to each other. A pre-heater assembly can be disposed within the heated cabinet for heating the material fed from the proportioner prior to its mixing with the material from the tank.

Claims

1. An applicator system for melting, mixing and applying a composition consisting of one or more materials, said applicator system comprising:

a tank having a material receiving area;

means for heating said tank to sufficiently melt a material disposed within the material receiving area;

a cabinet receiving heat from said means for heating;

means for removing melted material from said tank;

means for supplying a second material and a third material;

means for mixing the second material with the melted material; and

an applicator receiving the mixed second material and melted material from said means for mixing and the third material from said means for supplying.

2. The applicator system of claim 1 wherein said applicator is a plural component spray gun.

3. The applicator system of claim 1 wherein said means for supplying is a proportioner which supplies the second material and the third material in a predetermined ratio.

4. The applicator system of claim 1 wherein said means for mixing comprises:

a preheater disposed within said cabinet, said preheater having an inlet and an outlet, said preheater communicating with said proportioner through a first line connected between the inlet of said preheater and a first outlet of said proportioner;

a mixing block in communication with said preheater through a second line connected between the outlet of said preheater and an inlet of said mixing block, said mixing block also in communication with said means for removing, said mixing block receiving and mixing the melted material received from said mean for removing and the second material received through said preheater; and

a static mixer in communication with an outlet of said mixing block for transporting the mixed material;

wherein said static mixer, said mixing block and said preheater are all disposed within an interior area of said cabinet.

5. The applicator system of claim 3 wherein the mixed material is transported from said static mixer to the applicator through a heated hose connected to one end of said static mixer and to an inlet of said applicator.

6. The applicator system of claim 3 wherein the second line includes a check valve to prevent the melted material from entering the second line.

7. The applicator system of claim 3 wherein said mixing block includes a check valve to prevent the second material from entering said means for removing.

8. The applicator system of claim 3 wherein said preheater is a series of tubes in communication with each other.

9. The applicator system of claim 1 further including means for controlling the amount of heat received within said cabinet.

11. The applicator system of claim 1 wherein said applicator is a plural component spray gun.

10. An applicator system for melting, mixing and applying a composition consisting of one or more materials, said applicator system comprising:
