The invention relates to a plant for separating grinding slurry originating from grinding machines into metal chips and grinding oil. According to the invention, a carrier bowl (3) in a frame (1) is filled with a divided volume of the grinding slurry (10). The carrier bowl (3) has a perforated plate (4) having an edge (5) as a floor and a sieve-like intermediate floor (8). By means of a lifting device (2), the carrier bowl (3) is moved to the effective region of an inductor plate (9) serving as a heater. The induction heat heats the ferromagnetic steel or iron particles present in the grinding slurry (10). Said heating effects a reduction in viscosity of the grinding oil in the grinding slurry (10), from which substantial portions flow downward through the openings (6) or (7). In certain cases, the effect can be improved by placing a steel plate on the free surface (16) of the grinding slurry layer (10).

A process for breaking the wall of ganoderma spora with high wall-breaking rate (more than 99%) includes such steps as choosing pearl particles with different diameters from 2 mm to 5 mm, proportionally mixing them with ganoderma spora and water, ball grinding, separating pearl particles from wall-broken spora, drying and pulverizing.

The invention discloses a method for preparing a nitrogen-rich carbon-coated cobalt-containing compound without a solvent. The method comprises grinding and mixing a cobalt-containing compound and a nitrogen-containing ligand, then placing the mixture in a high-pressure reactor, carrying out a reaction process at a temperature of 140 to 350 DEG C to obtain a precursor, and carbonizing the precursor at a temperature of 300 to 1000 DEG C in a protective atmosphere to obtain the nitrogen-rich carbon-coated cobalt-containing compound having a high specific surface area and a mesoporous and microporous structure. The method has simple processes, is free of a solvent, realizes a high yield and control of nitrogen content and carbon content, greatly reduces a production cost and is conducive to industrial production.

The invention relates to an automobile coating parallel mechanism conveyer, which comprises two functional parts: a traveling mechanism and a lifting and turning mechanism. The traveling mechanism finishes the traveling and transporting functions of the conveyer; the lifting and turning mechanism consists of one or more parallel mechanisms; the body of the automobile or other objects to be conveyed are arranged on a moving platform of the parallel mechanism; and the parallel mechanism is driven to finish the lifting and turning of the object to be conveyed. The movement of the traveling mechanism is combined with that of the parallel mechanism; the body is driven to realize advancing and retreating, lifting, tilting or composite movement thereof so as to be fully stirred in an electrophoresis tank to achieve the purpose of completely eliminating bubbles on the top of the automobile body during the electrophoresis. Because the parallel mechanism is adopted by the conveyer, the bearing capacity of the conveyer is increased so as to be suitable for conveying the bodies of different types or sizes, and the flexibility of the conveyer is also increased; and because the suspending and conveying system has a gantry structure, the conveyer successfully overcomes the defect of dropping liquid pollution and is therefore an environment-friendly conveyer on the automobile coating production line.

The invention relates to an on-line monitoring oil-gas separation device for a transformer, and belongs to the technical field of power engineering. The device comprises an oil-gas separation chamber, a vacuum pump, an ultrasonic vibrator, a scavenge oil pump, a PLC control module, an electromagnetic valve, a liquid level detector, an oil-gas filter, a throttle valve and a connecting pipe. All electric parts are controlled by the PLC module to cooperate with each other to work in real time. The device utilizes a method of combining the vacuum pumping and the sonic oscillation principle for the oil-gas separation, so that the degassing efficiency is higher and the degassing process is faster; and moreover, the device also has the advantages of high automaticity, small volume and convenientarrangement, and is quite suitable for detecting faults based on dissolved gas in the oil of oil immersed type equipment such as a transformer and the like.

The invention relates to the field of waste recycling, and particularly relates to a production method of a reclaimed rubber. The production method of the reclaimed rubber comprises the following steps: collecting scrapped rubber materials; crushing the rubber materials so as to obtain granular raw materials; desulfurizing the granular raw materials so as to obtain activated rubber powder; milling the activated rubber powder so as to obtain the reclaimed rubber. The production method of the reclaimed rubber disclosed by the invention can be used for better overcoming the defect that in the prior art, large amounts of scrapped rubber products are directly discarded or collectively collected and then burned, so that the waste of raw materials and the environmental pollution are caused.
