There will be some troubles in heat pump dryer after long use. The following summarizes the common troubles and solutions of the dryer:

1. One-time drying of raw materials: the reason is that the dryer is too small, and the raw materials in the dryer are too much; it is also possible that the calculation of wind pressure and flow in the wind network is incorrect and incorrect; another reason is that the dryer operator is not familiar with the dryer, resulting in the improper use of the dryer. For the first reason, the dryer can be replaced with a larger capacity; it can also be loaded less each time; it can also increase the temperature of the dryer, but this method can easily cause fire in the dryer, so the dryer can also be changed. For the second reason and the third reason, it can be solved by contacting the drying equipment manufacturer. The former can require the dryer manufacturer to recalculate the air pressure and heat pump dryer flow, and then provide the design change plan according to the actual situation; the latter can consult with the dryer manufacturer to obtain the equipment instruction and learn the correct way to use the dryer.

2. The uneven drying and wetting of materials may be the improper use of drying equipment, or the material of dryer may be affected by low temperature into clusters. For the former, it is necessary to strengthen the technical training of operators so that they can master the operation skills skillfully. If the raw materials are clustered, they need to break up the drying raw materials and then dry them.

3. The material of the dryer can not be sucked away: the first reason is that the equipment of the dryer is improperly installed, the dryer leaks air or is incorrectly installed; the second reason is the design of the equipment of the dryer and the insufficient air pressure of the dryer. The former is to check whether the installation is correct by referring to the installation drawings, check whether the pipeline interface is leaking, and then solve the problem accordingly. The dryer manufacturers should bear the corresponding responsibility for the design of the dryer itself.

4. Fuel waste in drying equipment: If the heat preservation of equipment is poor, it needs to improve its heat preservation performance. It can be a layer of heat preservation material. If there is a problem in the design of dryer or heat pump dryer stove, it needs to be solved with the manufacturer.

5. Dryer raw material ignition: raw materials can not be sucked away, resulting in a fire in the dryer; it may also be that the dryer equipment is too small to achieve the drying effect and forced heating, resulting in fire; it may be that the dryer equipment is improperly used; furthermore, there is a problem in the design principle of dryer equipment. For the first reason, it is necessary to check whether the dryer equipment is installed correctly, whether it leaks air or increases air pressure; for the second reason, the dryer can be reformed or replaced with a larger capacity dryer; for operators who do not understand, they can be familiar with the dryer again and learn the operating precautions of the dryer again; for the problem of the equipment itself, the manufacturer should be required to replace or reform it. Repair the dryer.

6. Fire of heat pump dryer: This may be because the temperature of the dryer is too high, which causes fire and combustion in the drying equipment; it may also be due to the blockage of the dryer. For the former, the temperature of the dryer should be lowered, and for the latter, the dryer equipment should be cleaned to keep the dryer unblocked.
