The invention discloses a waste lithium battery black powder crushing and sorting device and a recovery process in the technical field of waste lithium battery black powder recovery, and the waste lithium battery black powder crushing and sorting device comprises a feeding unit, an electrode material dissociation unit and a sorting and enriching unit which are sequentially arranged along the material flow direction, comprising an active material collection system, a metal current collector separation system and an electrode active material purification system, and inert gas protection and temperature monitoring are introduced in the core link of crushing and dissociation, so that the risk of combustion explosion is eradicated fundamentally, the chemical stability of an electrode material is guaranteed, and the service life of the electrode material is prolonged. Secondly, shearing and crushing are adopted to optimize the dissociation effect, pneumatic separation, eddy current and magnetic separation multi-stage and precise separation technologies are combined, a returned material crushing closed circuit is innovatively introduced, the black powder collection rate and the separation purity and total recovery rate of copper and aluminum metal are greatly improved, and finally, the recovery rate of the copper and aluminum metal is increased. All the units are integrated into a continuous automatic system, and maximum utilization of resources is achieved.

This invention relates to the field of in-situ asphalt pavement recycling technology, specifically a high-frequency vibration scraping device, including a traveling vehicle, a blade holder, and an impact blade. A support frame is located at the front of the traveling vehicle, and a rotation adjustment component is provided between the support frame and the blade holder. A depth adjustment component is mounted on the rotation adjustment component. A high-frequency hydraulic impact device is mounted on the blade holder, and the impact blade is located at the front end of the high-frequency hydraulic impact device. A limiting seat for guiding the impact blade is provided on the blade holder. This high-frequency vibration scraping device allows workers to flexibly adjust the tilt angle of the blade holder and blade during asphalt pavement removal by rotating the adjustment component. This enables the device to adapt to the scraping angle required for removing different pavements, achieving precise and highly adaptable removal operations. The depth adjustment component precisely controls the cutting depth of the blade through a screw mechanism, which facilitates the separation of the surface layer material from other layers.

This application relates to the field of municipal road construction technology, and in particular to a hydraulic ring-cutting road surface demolition device that adapts to different manhole cover sizes. The device includes a frame, a power lifting assembly, a hydraulic breaker assembly, and a clamping assembly. The frame includes a fixing plate with a circular through hole on its upper surface, and two inclined supports are fixedly connected to the upper surface of the fixing plate. By setting up the hydraulic breaker assembly, this application utilizes four hydraulic telescopic rods arranged in a cross shape to drive the adjusting block, which in turn drives the breaker head to extend and retract radially. This allows for precise adaptation to various sizes of conventional municipal manhole covers, solving the problem that traditional equipment can only adapt to fixed-size manhole covers and cannot meet the needs of concentrated operations with multiple types of manhole covers in old residential areas. This significantly expands the applicability of the equipment. It achieves neat ring-cutting of the road surface around the manhole cover, resulting in a smooth cut, avoiding excessive damage and road surface cracking, reducing the workload and cost of subsequent road repair, and meeting the asphalt pavement smoothness requirements after the renovation of old residential areas.

The crushing device comprises a top plate, side plates are fixedly connected to the two sides of the bottom of the top plate, a material box is arranged in the center of the lower end of the top plate, a sieve plate is fixedly installed at the position, close to the top, in the material box, and an air cylinder is fixedly installed in the center of the top of the top plate; a hollow plate is arranged at the position, close to the top, between the two side plates. According to the grinding device for chilli sauce production, through the design of the material box, the sieve plate, the air cylinder, the reciprocating lead screw, a motor, a first gear, a second gear, a hollow cylinder, a spring, an elastic block, an extension rod and a grinding roller, during grinding operation, motor driving is matched with reciprocating lead screw transmission, and the grinding roller efficiently and uniformly reciprocates in the material box; and meanwhile, the air cylinder drives the crushing roller to ascend and descend, all-around rolling is conducted on the chilies, the rapid and thorough crushing effect is achieved, the production efficiency is greatly improved, and in the crushing process, the spring assemblies endow the crushing roller with the excellent self-adaptive capacity.
