4results about How to "Purify the working environment" patented technology

This invention relates to the field of fiber processing equipment, specifically to a high-efficiency, low-dust fiber slicing device and method, comprising a frame and a slicing table. The slicing table is horizontally positioned at the bottom of the frame. An air collection hood, flush with and fitted to the bottom of the slicing table, is located inside the frame. A cutting section is positioned above the slicing table, and a transverse moving frame is fixed to the bottom of the frame. A longitudinal moving frame, supporting the cutting section, is horizontally positioned at the top of the transverse moving frame. The transverse and longitudinal moving frames form a sliding platform supporting the transverse and longitudinal movement of the cutting section. Vertically penetrating fixed air holes are densely distributed on the top side of the slicing table. The air collection hood includes a horizontally extending air box. The beneficial effects are: this invention employs a negative pressure adsorption flexible conveying structure, utilizing negative pressure holes on the roller surface to periodically adsorb and lift the fiber roll to complete material feeding, avoiding compaction and deformation of the fiber material, preserving the loose porous structure of the material, and improving the processing quality of the finished slicing product.

This utility model belongs to the technical field of ultrasonic spraying equipment, and aims to provide an ultrasonic spraying device for high-temperature pyrolysis. It includes an outer frame with an opening door on the front and a control computer on the side, with an electrical control chamber below the control computer. A heating module is located at the bottom of the outer frame, and a drive power supply is located on the side of the heating module. Inside the outer frame, a water-cooled ultrasonic spraying assembly and an integrated ventilation system are installed. The water-cooled ultrasonic spraying assembly is connected to a three-axis motion module. A liquid supply assembly is located at the upper end of the outer frame, connected to the water-cooled ultrasonic spraying assembly, supplying spraying solution to the assembly. This utility model features a compact structure, small size, suitability for high-temperature spraying environments, convenient installation and disassembly of the heating module, and good residual gas ventilation. It can be widely used in the field of ultrasonic spraying production technology in high-temperature environments.

The utility model discloses a kind of surface treatment devices of hydraulic oil cylinder production, comprising: workbench;Vertical plate, vertical plate is fixedly arranged on the upper side wall of workbench;Cylinder, cylinder is fixedly arranged on the side wall of vertical plate, the output shaft of cylinder passes through vertical plate and is fixedly connected with motor box, motor box is installed with motor, the output shaft of motor passes through motor box and is fixedly connected with turntable, away from the side wall of vertical plate, compared with prior art, by the positioning mechanism set, it can be tensioned positioning from oil cylinder inside, so that oil cylinder surface is completely exposed in the action range of arc polishing plate, thoroughly eliminates polishing dead angle, can realize the all-around, no missing polishing to oil cylinder surface, significantly improve polishing efficiency and surface treatment quality;By setting dust hood, by air pipe and dust collector are connected, in polishing process, dust hood can timely suck away the dust generated, effectively purify working environment, greatly reduce the harm of dust to operator health.

This utility model relates to the field of laser cutting technology for waste batteries, and discloses a laser cutting device for waste battery recycling, including a conveyor belt on which multiple sets of batteries are equidistantly distributed. Cutting frames are fixedly installed at both ends of one side of the conveyor belt, and a laser cutting machine is fixedly installed at the top center of the cutting frames. A laser cutting head is connected to the bottom of the laser cutting machine. In this utility model, the clamping and rotating assembly, when driven, drives the first gear to rotate. Since a driving arm is rotatably installed on the side wall of the first gear, and the other end of the driving arm is rotatably installed with a pressing rod, it can drive a sealing plug installed at the other end of the pressing rod to reciprocate within a sealed container. When the sealing plug moves to the right within the sealed container, a negative pressure is created in the cavity between the sealed container and the sealing plug. This negative pressure is then transported through the air inlet pipe and the smoke extraction pipe to the smoke hood, absorbing the fumes generated by the laser cutting machine and greatly purifying the working environment.
