And through the design of mechanical structures such as the sliding blocks and the connecting rods, flexible adjustment and stable supporting of the heat dissipation outer ring are achieved, the heat dissipation efficiency is improved, and the stability of the structure is enhanced.

The utility model relates to the technical field of display screen recovery, in particular to a multifunctional fragment sorting device for waste CRT display screen recovery, which comprises a first sorting mechanism and a second sorting mechanism, the first sorting mechanism is mounted on the second sorting mechanism, and the discharge side of the first sorting mechanism is communicated with the inside of the second sorting mechanism; the first sorting mechanism comprises a sorting cylinder and a magnetic sorter arranged in the sorting cylinder. Various metal substances in the CRT display screen fragments are separated and collected through the first sorting mechanism and the second sorting mechanism, iron metal in the CRT display screen fragments is separated and obtained through the first sorting mechanism, and then non-iron conductive metal in the CRT display screen fragments is separated and obtained through the second sorting mechanism. And efficient and rapid separation of various metals is realized.

The invention relates to the technical field of liquid crystal screens, in particular to a liquid crystal screen structure simulating a crt kinescope and an optimized display method of the liquid crystal screen structure, and solves the problems that when an existing liquid crystal display is used for displaying images, light rays are generally perpendicular to the surface of the display, so that pictures cannot be clearly watched from a lateral view angle, and the stereoscopic impression of the pictures is limited. Comprising a liquid crystal display mechanism, the liquid crystal display mechanism comprises a liquid crystal screen body, a light guide arrangement unit is installed on the rear end face of the liquid crystal screen body, the light guide arrangement unit is composed of a liquid crystal layer, a light-transmitting installation substrate, a light deflection frame strip and a light perpendicular incidence plate, and the light-transmitting installation substrate is fixedly installed on the front end face of the liquid crystal layer. A light perpendicular incidence plate is installed in the middle of the front end face of the light-transmitting installation substrate, and a plurality of light deflection frame strips are installed on the outer side of the light perpendicular incidence plate. The crt kinescope is simulated through the liquid crystal screen, the visual angle of the liquid crystal screen can be effectively increased, and the stereoscopic impression of a picture is higher.

The application relates to the field of display recycling, in particular to a CRT display device disassembling and separating equipment. The equipment comprises an isolation box, a power gear is rotationally installed on the top wall of the isolation box, an adjusting block is fixedly installed at the bottom end of the power gear, and a sucking disc clamping device is rotationally installed at the bottom end of the adjusting block. The sucking disc clamping device is arranged. In working, the cut CRT screen is divided into a plane glass at the upper part and a conical glass at the lower part. The upper sucking disc and the bottom sucking disc are used for realizing classified clamping and conveying of the cut CRT screen. The fluorescent powder suction nozzle in the dust suction device moves up and down in the moving groove, realizes cleaning and collection of the fluorescent powder in the CRT screen, reduces the splashing degree of the fluorescent powder in the CRT screen when workers disassemble the CRT screen, and reduces the radiation to the workers.

The utility model relates to the technical field of CRT (cathode ray tube) display recycling, in particular to waste CRT display glass cleaning equipment with an automatic feeding function, which comprises a material carrying frame, a conveying cleaning mechanism is mounted at the top of an inner cavity of the material carrying frame, and a driving motor is arranged on the front side of the material carrying frame. A sponge bearing roller is movably installed in the inner cavity of the material carrying frame and located at the bottom of the conveying cleaning mechanism, a positioning frame is fixedly connected to the bottom of the inner cavity of the material carrying frame, conveying grooves are formed in the tops of the left side and the right side of the material carrying frame, and the bottoms of the left side and the right side of the inner cavity of the material carrying frame communicate with blow-off pipes. Through the arrangement of the driving motor, the conveying and cleaning mechanism, the sponge bearing rollers and the positioning frame, the display glass feeding device has the advantages of uniform cleaning and feeding conveying, and the display glass can be conveyed rightwards for feeding through synchronous rotation of the multiple driving rollers; and meanwhile, the elastic cleaning brush is used for brushing the glass, and the actual machining requirement is better met.
