Overturning and discharging device

Abstract

The invention relates to an overturning and discharging device for a baked graphite electrode saggar. The device comprises an upper cover rotating part (3), a lower cover rotating part (5), an overturning part (4), a hydraulic system (14), a coupling (1), a power shaft (8), a main shaft support frame (7), a support shaft (6), a support device (9) and the like, and is characterized in that: the support shaft (6) of the overturning part (4) is connected with the power shaft (8); a power hydraulic cylinder (15) is connected to the power shaft (8) by the coupling (1); the upper cover rotating part (3) and the lower cover rotating part (5) are provided with lateral hydraulic cylinders (2); the overturning part (4) is connected with the support device (9) by the support shaft (6); and ground nails (10) are arranged on a ground base by the support device (9). By the overturning and discharging device provided by the invention, the damage of dust generated by the conventional discharging method to workers can be greatly reduced, the work efficiency can be improved, and both waste of filling materials and cost can be reduced.

Description

technical field [0001] The invention relates to an overturning and unloading device, in particular to an overturning and unloading device for firing graphite electrode cauldrons. The invention can also be used in other industries. Background technique [0002] In the production of graphite electrodes, when tunnel kilns or car bottom furnaces are used to roast products, the method of roasting containers is mainly used for production. The roasting containers are generally made of steel or refractory materials. Filling materials are added to protect the product, and then sent to the kiln for roasting. The filler generally adopts quartz sand or metallurgical coke. The purpose of using the filler is to reduce the air oxidation of the product during the roasting process and prevent the product from being deformed during the heating stage. At present, when tunnel kilns or car bottom furnaces are used to roast graphite electrode products, the main unloading method is manual unloadi...

AI Technical Summary

Problems solved by technology

[0004] 1. The cauldron is easily deformed under the dual effects of high temperature and pressure during roasting, and accidents such as the cauldron dumping are easily caused during the transportation and overturning of the cauldron; Falling under the action of gravity is easy to cause damage to roasted products

[0005] 2. The separation of fillers and roasted products and the recovery of fillers require manual operations, resulting in low production efficiency and high labor intensity. In order to ensure that the fillers can be recycled, some resources will be wasted in the recycling process

[0006] 3. In addition, more dust is generated during the separation process of filling materials and roasted products from the sintering box, while the existing technology requires manual on-site operation, which is harmful to the health of workers and has hidden dangers of safety accidents
