Precautions and skills to avoid caking of sludge low temperature dryer

The reason why the sludge with high humidity and high viscosity is difficult to dry is because during the operation of the sludge low-temperature dryer, the high humidity and viscosity sludge is easy to adhere and agglomerate. If the sludge sticks to the cylinder wall, it will not only affect the drying quality, but also affect the service life of the sludge low-temperature dryer. So what do you need to do to avoid the problem of sludge low-temperature dryer caking? Next, I will introduce.

1. Upgrade drying process

The traditional single drum dryer process is relatively simple, hot air and materials directly in and out, suitable for drying materials with little difficulty. In view of the high humidity and high viscosity sludge, if we want to solve the caking problem of sludge low-temperature dryer, we need to reform and upgrade the equipment. ZJN sludge low-temperature dryer adopts a three-layer sleeve structure. The materials and hot air move in the order of inner cylinder, middle cylinder and outer cylinder, which greatly increases the material travel, increases the utilization rate of heat energy and speeds up the drying speed.

In addition, in ZJN sludge low-temperature dryer, the "rotary rake crushing" breaking device and the intertwined distribution lifting device are also set up in the cylinder. The reformed cylinder structure greatly increases the contact area between the wet sludge and the hot air flow, so that the sludge is largely dispersed and continuously lifted and scattered, which is in the high-speed operation activities, effectively avoiding the sludge sticking and agglomeration.

2. Choose professional manufacturers

In general, when purchasing the sludge low-temperature dryer, we should choose a professional manufacturer. In this way, not only the raw materials, structure, process and quality of the equipment are guaranteed, but also the after-sales service is better. The failure rate of such equipment in the use process is low and the service life is relatively long.

3. Proper use of equipment

The operators shall work after training. When operating the equipment, they shall pay attention to the operation according to the regulations, correctly switch on and off the machine, pay attention to the barrel temperature, feeding speed and feed rate, so as to prevent the equipment from overload operation. If there is overload phenomenon in the normal operation of the sludge low-temperature dryer, it will not only affect the drying quality of the materials, but also cause the material sticking in the cylinder, which will affect the service life of the equipment for a long time.
