Abstract

A machine for smashing thermosetting materials includes a high-pressure direct drive pump assembly, a mixing tank, a chemical solution tank, a hydraulic-control solenoid valve, a low-pressure auxiliary pump, a directional valve set and a controller. The controller, connected signally with the high-pressure direct drive pump assembly, the mixing tank, the chemical solution tank, the hydraulic-control solenoid valve, the low-pressure auxiliary pump and the directional valve set, is used to control opens and closes of the first directional valve, the second directional valve, the third directional valve and the hydraulic-control solenoid valve so as to supply the chemical solution in the chemical solution tank to the mixing tank.

Claims (11)

1 . A machine for smashing thermosetting materials, comprising:

a high-pressure direct drive pump assembly;

a mixing tank;

a chemical solution tank;

a hydraulic-control solenoid valve, connected spatially between the chemical solution tank and the mixing tank;

a low-pressure auxiliary pump;

a directional valve set, including a first directional valve, a second directional valve and a third directional valve, the first directional valve being configured to connect spatially between the high-pressure direct drive pump assembly and a nozzle, the second directional valve being configured to connect spatially between the high-pressure direct drive pump assembly and the mixing tank, the third directional valve being configured to connect spatially between the chemical solution tank and the mixing tank; and

a controller, connected signally with the high-pressure direct drive pump assembly, the mixing tank, the chemical solution tank, the hydraulic-control solenoid valve, the low-pressure auxiliary pump and the directional valve set,

wherein the controller is configured to control opens and closes of the first directional valve, the second directional valve, the third directional valve and the hydraulic-control solenoid valve.

2 . The machine for smashing thermosetting materials of claim 1 , further including a chemical-solution refill barrel connected signally with the controller, the directional valve set further including a fourth directional valve connected spatially with the chemical solution tank and the chemical-solution refill barrel, the controller being configured to control open and close of the fourth directional valve.

3 . The machine for smashing thermosetting materials of claim 1 , wherein the high-pressure direct drive pump assembly includes a solution tank, a direct drive pump and a boost source connected between the solution tank and the direct drive pump.
