The application provides a front and rear and lifting adjustable calender glass baffle device, which is installed on both sides of a calender glass overflow port and comprises a lifting baffle assembly, which is installed at both ends of a lip brick in a front and rear adjustable mode; and a sealing brick group, which is installed at both ends of a tail brick and follows the displacement of the lifting baffle assembly. The lifting baffle assembly is installed with a waist-shaped hole in the base, so that the lifting baffle assembly can move up and down and front and rear on the calender to freely adjust the position of the calender to balance the temperature of the upper and lower calender rollers and keep the distance between the lower calender roller and the lip brick. The front and rear expansion of the sealing brick group can compensate the gap caused by the front and rear movement of the lifting baffle assembly, prevent the overflow of glass liquid between the baffle assembly and the sealing brick group, and solve the problem of the unbalanced temperature of the upper and lower calender rollers in the calender glass production process.

The utility model belongs to pipe belt machine technical field, concretely relates to a pipe belt machine truss and pipe belt machine, including truss body and set up a plurality of support frame on truss body, each support frame sets up the roller mechanism, each roller mechanism has a plurality of the roller that can rotate around own axis line and the passage that is used for the pipe belt machine's conveyor belt to pass through and is formed between a plurality of rollers, the truss still includes a plurality of limiting mechanisms that set up on the truss body, each limiting mechanism forms the limiting hole for limiting the activity of traction rope, so that when traction rope pulls the conveyor belt, traction rope is located in the limiting hole, further make traction rope pass through the passage when away from the roller, the utility model in the process that traction rope pulls the conveyor belt, traction rope is limited in the limiting hole, so that in the traction process, traction rope and equipment always keep a certain distance, traction rope is away from the roller and truss body, can avoid traction rope to damage the surface of roller, need not manual intervention, greatly improve traction rate.

The invention relates to the technical field of wafer manufacturing equipment, in particular to a heat shield radiation device for improving the crystallization rate of heavily doped red phosphorus single crystals, which comprises a support ring, an upper heat insulation material mounted at the top of the support ring, and an outer heat shield assembly mounted at the bottom of the support ring, the outer heat shield assembly comprises a heat shield outer cover and a heat shield inner cover, the heat shield outer cover and the heat shield inner cover are both of an annular structure and are connected with each other, a cavity is formed between the inner cover and the outer cover, and the cavity is filled with an inner heat insulation material; the heat shield inner cover is composed of an inner upper cover, an inner lower cover and an inner upper molybdenum cylinder, the inner upper cover and the inner upper molybdenum cylinder are both of a V-shaped structure, the inner upper molybdenum cylinder is arranged on the inner wall of the inner upper cover, and the inner lower cover is of a splayed structure and is in butt joint with the inner upper cover.
