Analysis of the hazards of the outlet lock failure of the double-cylinder dryer equipment and how to solve it

How to solve the problem of the outlet lock failure of the double cylinder dryer drying system? Since the twin-tuber dryer equipment was put into production, the clay mine contains a large amount of sandstone, and the particle size is sometimes larger than 200mm, which causes the outlet of the double-barrel dryer to fail. How to solve the problem of the outlet lock failure of the double cylinder dryer drying system? Since the twin-tuber dryer equipment was put into production, the clay mine contains a large amount of sandstone, and the particle size is sometimes larger than 200mm, which causes the outlet of the double-barrel dryer to fail. As a result, four major hazards are brought about: First, the condensation of the flue gas into the electric precipitator causes corrosion of the plates and reduces the efficiency of dust collection. The emission concentration reaches 76.95g/m3), which is not only wasteful, but also has serious pollution, directly affecting the production environment and the physical and mental health of the workers. Second, the ventilation in the double-cylinder dryer is insufficient, the heat transfer is poor, the thermal efficiency is low, and the production is not High, the third is that the finished screw conveyor often has large sandstone stuck, which causes the conveyor to break the shaft and burn the motor, and the fourth is due to the unreasonable structure of the bucket hoist in the storage chain, the finished reamer and the bottom of the hoist Insufficient height difference limits delivery capacity. The bottom of the ash is accumulated, the tensioning device of the hoist has little effect, the swinging amplitude of the hopper is large and the material is unloaded, and the unloading of the material is not clean, and serious accidents such as pulling, grooving or even breaking the chain and falling the frame often occur. Due to frequent accidents in the clay system, the number of stops is increasing, the production is extremely abnormal, and the supply of soil materials is insufficient, which also adversely affects the normal production of the raw material grinding system. In response to the above problems, the relevant engineering and technical personnel of our company have taken the following measures:
1. Change the original hoist shallow bucket to deep fight;
2. A feeding plate is added at the discharge port of the hoist, and the rotation speed is adjusted several times at the same time;

3. At the outlet of the double-cylinder dryer, a purlin is added at the interface between the nozzle and the reaming knife to block the large sandstone, but the final effect is not satisfactory, and the problem is still not completely solved. Zhengzhou Hengxing Equipment Co., Ltd. has domestic first-class production equipment and sophisticated testing instruments. Every step of the double-tuber dryer products has undergone rigorous testing to ensure that the products meet the highest standards at the factory.
