2results about How to "Increase product yield" patented technology

This disclosure relates to the field of winding machine drum replacement fixture technology. One embodiment of this disclosure provides a winding machine drum replacement fixture, which includes a fixed base, multiple fixing screws on both sides of the fixed base, a V-shaped bracket, a clamping frame, a clamping plate, a clamping mechanism, a connecting frame, and a buffer-type pressing assembly. The V-shaped bracket is installed on the upper side of the fixed base and is used to support the drum. Multiple clamping frames are installed on the inner side of the V-shaped bracket, and the multiple clamping frames are symmetrically arranged. The clamping plate is inserted into the inside of the clamping frame and can move vertically inside the clamping frame. The clamping plate is used to limit the movement of the drum. The clamping mechanism is installed on the outer side of the clamping frame and is used to clamp the clamping plate. The connecting frame is installed on the upper side of the clamping plate and moves synchronously with the clamping plate. The above technical solution is used to solve the technical problem of excessively long maintenance and repair time in the winding area of ​​the prior art.

The utility model discloses high-purity quartz sand oxygen-free chlorination roasting equipment which comprises a roasting section provided with a heat preservation furnace body and a heater, the heat preservation furnace body is arranged on the periphery of the heater in a sleeved mode, the two ends of the heater are respectively provided with a ventilation connector which reacts with sand inside the heater, and the heater maintains an internal oxygen-free environment through the ventilation connectors. Relates to the technical field of quartz sand oxygen-free chlorination roasting. Compared with traditional high-temperature chloridizing roasting equipment, the high-temperature chloridizing roasting equipment has the advantages of being high in heating speed, high in heating efficiency, capable of saving electricity and energy, even in heating, capable of achieving selective heating, good in environmental protection, capable of improving labor conditions, small in occupied area, capable of saving investment, low in maintenance cost and the like, and meanwhile the yield, quality and grade of products can be improved. Meanwhile, new impurities can be prevented from being introduced in the reaction process, and oxidation reaction is avoided.
