The application discloses a dry-type hollow shunt reactor overvoltage protection device and belongs to the technical field of overvoltage protection of power transmission and transformation equipment. When system operation overvoltage occurs, the frequency absorption unit can reduce the oscillation frequency of overvoltage, slow down the rising front of overvoltage, solve the damage of high-frequency components to the reactor winding, and inhibit the overvoltage peak value. When the frequency absorption unit cannot inhibit the overvoltage peak value, the overvoltage absorption unit plays a role in limiting the overvoltage peak value, and the insulation level of the reactor is enhanced. Through the application of the voltage monitoring and conversion unit, when the reactor is normally operated or the overvoltage is lower than the operation threshold value, the high-speed control switch is turned on, the explosion-proof separation unit is short-circuited and bypassed, and the frequency inhibition absorption unit and the overvoltage absorption unit bear the main protection task. When the monitored voltage exceeds the set threshold value or the absorption unit fails or is subjected to thermal breakdown, the high-speed control switch is turned off, the explosion-proof separation unit is connected to the circuit, the faulty unit is timely removed, and the fault expansion is prevented.

This invention belongs to the field of engineered wood products manufacturing, specifically a method for preparing low-formaldehyde finger-jointed boards based on bio-based modified adhesives. The method includes preparing an adhesive composed of modified soybean protein, non-formaldehyde crosslinking agents, micro / nano cellulose, nano-silica, and epoxidized vegetable oil elastomers; pre-treating the wood and cutting the finger joints; applying a sealing liquid via atomization for end-face damping treatment; performing quantitative adhesive application and stepped butt joint molding; and employing a multi-stage hot-pressing process involving preheating penetration, high-temperature curing, and cooling and pressure holding. Through the above technical solution, this application can achieve the formation of a dense adhesive film at the finger joint interface, significantly improving bonding strength and stability while reducing formaldehyde release.

This invention relates to the field of wet lithium battery recycling technology, specifically to an ultrasonic-assisted wet stripping device for waste lithium battery black powder. The device includes a reaction vessel, a drive mechanism, and a stripping mechanism. The stripping mechanism comprises a stator unit and a rotor unit. The rotor unit includes a filter cylinder and grinding media. The bottom of the filter cylinder has a feed inlet and a spiral blade. The stator unit includes an ultrasonic component and a turbulence component. By constructing a stripping mechanism with the stator and rotor units coaxially nested, the device utilizes the microscopic cavitation effect of ultrasound and the gentle mechanical scrubbing of the grinding media to replace the harsh blade cutting. This solves the problems of insufficient microscopic adhesion and incomplete stripping caused by relying solely on mechanical cutting in existing technologies. Simultaneously, it avoids the problem of excessive pulverization of the current collector, which contaminates the black powder, thus achieving efficient and complete stripping of the black powder and lossless recovery of the current collector.
