The invention discloses a deep sea cobalt crust shattering method and a device thereof; the method adopts mechanical tooth and water jet to shatter deep sea cobalt crust in a combining way, and high pressure water flow is jetted to impact a stress area of the deep sea cobalt crust to assist to shatter the deep sea cobalt crust when mechanical force is applied by the mechanical tooth to shatter the deep sea cobalt crust. The device comprises a mechanical crushing device and a water injector which are used for acting on the deep sea cobalt crust together; the water injector includes a water tank, a high pressure pump, a first valve, an energy accumulator, a second valve, a controller and a nozzle; wherein, the water tank, the high pressure pump and a check valve are sequentially connected with each other in series and then are connected with the energy accumulator which is also connected with the nozzle by the second valve. The invention can reduce the impact load acting on a shattering head in the crushing process of the cobalt crust, and improve the travelling speed of a mining machine.

The invention relates to a mechanism which can replace manpower for moving ropes, in particular to a numerical-control rope moving mechanism used for achieving automation of a rope moving procedure in the assembling process of steel wire rope vibration isolators. The numerical-control rope moving mechanism comprises a base. A connecting plate is fixedly arranged on the front end portion of the base, a stepping motor is fixedly arranged on the connecting plate, a small synchronous pulley is connected at the output end of the stepping motor, linear guide rails are arranged on the two sides of the upper end portion of the base in the width direction respectively, a ball screw is arranged between the two linear guide rails, a large synchronous pulley is fixedly connected to the end portion of one side, close to the connecting plate, of the ball screw, and the large synchronous pulley and the small synchronous pulley are connected through a synchronous belt. According to the numerical-control rope moving mechanism, manpower is replaced by mechanical force for moving the ropes, and labor intensity of operators is reduced. Meanwhile, the problem that two or more people are needed for carrying out rope moving operations in the assembling process of the large-size steel wire rope vibration isolators is solved, manpower is saved, and cost is reduced.

The invention relates to a method for carrying out mechanical activating high-concentration pulp grinding in a wet state. The specific steps comprise: adding a weighed pulp into a beaker containing water, adjusting to achieve a to-be-grinded raw material with a concentration of 1-5%, and uniformly stirring for 10 min at a room temperature; and placing the blended raw material and a grinding mediumaccording to a ratio of 100 g:150-250 g into a ball mill, inflating with CO2 gas with a pressure of 0-2 MPa, and grinding for 0.5-3 h at a temperature of 40-120 DEG C to form a pulp, wherein the process after the pulp preparing is the same as the original papermaking process. According to the present invention, the plant pulp is mechanically activated by the high energy ball mill to replace the traditional pulp grinding method, such that the squeezing, rubbing and cross-linking among the plant fibers is performed through the mechanical force so as to improve the pulp refining degree and the fiber kinking index, increase the hydration reaction interface, reduce the water consumption, and significantly improve the cohesion, the folding resistance and the tensile strength of the paper.
