Analysis of the causes of the failure of the vegetable dryer

2020-03-04

1. The vegetable dryer is heated by stopping the conversion of airflow in the heating chamber to evaporate the moisture, so the heating chamber must have a good seal. If the heating chamber of the dryer is found to be tight, we can turn the head tube After the body and dryer cylinders are all corrected, they are welded, and then the split material retaining ring is bolted to the simplified head. Next, the sealing flange is placed in a proper position, fixed with the frame of the boiling furnace, and filled with the furnace brick of the sealed outer ring. Then use the pressure block to install the spring leaf. In order to prevent the spring plate from being abraded, a section of ordinary steel tube jacket with a thickness of 8mm is specially installed on the cylinder body 7 and a wire rope is used to hang the weight around the spring plate. After this treatment, the tightness of the heating chamber can be guaranteed.

2. The cylinder is oscillating when the dryer is in operation. The reason is that the side of the concave joint of the rolling ring is not clamped. The elimination method is to use a pad to keep the rolling ring and the concave joint uniform and properly clamped. Prone to accidents.

3. The chain of the dryer is broken, which is mainly due to the excessive load on the scraper in the work, and the corrosion of the chain by the water in the tank, which will reduce the chain and cause another one. The chain also broke. Of course, if manufacturers want to reduce consumption costs, increase profits, and reduce the quality of chain manufacturing, they will also cause chain breaks. However, friends of the users must pay attention to the maintenance of the chain in the process of using the dryer, and properly increase the material to prevent the chain from overloading.

4. The material does not make "reciprocating motion" in the dryer drum. Because the "reciprocating motion" and "block multi-loop motion" of the material in the dryer are two different concepts of the process flow, the material in the drum is very It will be drawn away by the wind soon. As a result, the storage amount of the material in the drum is too low, and the dynamic and static contact area of ​​the material and the hot air is reduced.

5. The reason why the temperature inside the dryer does not go up: The air outlet is opened too large, and the exhaust is too fast. Cleaning method: Cover the filter with half a piece of cardboard and half close the damper.

6. Reasons for the low rotation speed of the drum of the dryer drum: The tension of the triangle tape is not enough. Cleaning method: Adjust the adjustable parts to increase the tension.
